In a modernized version of the tent "LOTOS Cube Professional M" The following changes and additions have been made:

The mechanism for folding the frame arcs (hub) is made of aluminum alloy. The cast aluminum “hub”, with its high rigidity, has a fairly high fragility, which is fraught with breakdowns of this element under increased loads. If the “hub” design is made thicker, this will not lead to a noticeable improvement in strength (voids form in thick-walled cast elements), but will only increase the dimensions and weight of the product.
In order to maximize the strength of this “hub”, it was decided to combine manufacturing materials. The upper part of the “hub”, which bears the maximum load, is reinforced with a 3.0 mm steel plate, this combination creates maximum effect rigidity and strength.
The reinforced “Hub” withstands very high mechanical and temperature loads and becomes one of the strongest, most reliable and durable elements in the tent.

How to upgrade the first version of the LOTUS Cube Professional tent? (production until 02.2015)

A feature of all improvements is full compatibility updated elements with the first 2014 model. This allows users who purchased the first version to replace the necessary components, while the cost of all replaced elements will not be more difference in cost between the modernized LOTOS Cube Professional M and the first basic version of 2014.

In order to replace the “12 mm tube with spring” element with a new “14 mm tube with spring” you must:

• Remove the old tube from the tent. To do this, you first need to pull the rod out of the tube as shown in the video. Then disconnect the tube from the awning by drilling or cutting off (with wire cutters) the rivet holding the tube in the awning sleeve.

• Attach the new tube to the canopy sleeve using a wire clip secured to the tube. In this case, the tube must be inserted into the tent sleeve as far as it will go.

• Insert the rod into the tube as shown in the video.

In order to strengthen the “hubs”, it is enough to secure the plate as shown in Figure No. 3.
When installing the plate on the “hub”, it is necessary to press it very tightly to the surface of the “hub” with a fixing nut. There should be no gap left between the plate and the hub. To securely fix the nut, it is recommended to use a second locknut.

• designed to create reliable connections for furniture pipes.
• They are used for fixing pipe connections for both round and profile pipes.
• They have a wide variety of sizes, one or two buttons.
• Can be used for pipes with outer diameters from 4 to 60 mm with different wall thicknesses.
• Springs with locking button very easy to use.
• Based on the material used, there are two options:
  1. Springs made of structural spring steel coated with 65MnNickel Plated;
  2. Springs from of stainless steel;
• Stainless steel springs are used in products that come into contact with river or sea water - in the manufacture of parts for boats, catamarans, etc. In all other cases, it is recommended to use nickel-plated steel springs. They have a weather-resistant coating.
• The possible sizes of springs with a button can be found in the table on the website page.

For reference

Steel grade 65Mn (65MN Carbon steel) - analogous to 65G. This is tool carbon steel. Has the ability to withstand shock loads. The hardness of steel 65Mn is 50-53HRC.
Class: structural spring steel.
Use in industry: springs, springs, thrust washers, brake bands, friction discs, gears, flanges, bearing housings, clamping and feed collets and other parts that require increased wear resistance.
Nickel Plated is a coating, literally - galvanic nickel or nickel applied by galvanic means. Nickel coatings have high corrosion resistance, high hardness and good decorative properties.

Springs with a button are used for fixing pipe structures, as well as in structures that require height adjustment.
Flat springs are indispensable in any pipe structures that should not be “accidentally” disassembled.

Suitable for use with pipes with outer diameters from 10 to 60 mm. Single-sided and double-sided spring-loaded snap buttons are available.

Spring button latches can be manufactured depending on their environment further use, or from structural spring steel with nickel electroplated coated or stainless steel. At the same time, stainless steel spring buttons must be used in products that will come into contact with sea water - oars, masts for yachts, etc. In all other cases, it is recommended to use spring steel fasteners.

Advantages of using push-button clamps for pipe connections:

• the issue of connecting pipe structures without the use of special tools is resolved
• pipe connection using push-button springs - very reliable, with a non-opening guarantee
• spring push-button latches can be used not only for round, but also for square pipe
• the button spring is non-removable and remains in the pipe, thus eliminating the possibility of losing hardware

If you have doubts or questions about how to choose the optimal spring push-button clamp for connecting pipes that best suits your goals and objectives, then you can use our table.

Table of types and sizes of spring push-button clamps for connecting pipes

Demountable connection of two pipes using a locking button. Scope of application.

The areas of use of the method of connecting pipes of different diameters using spring push-button clamps are very extensive.

For example, when using thin-walled furniture pipes in a wide variety of designs and furniture - bunk beds,

chairs, ladders, tables, cots, all kinds of fences and barriers, tents and canopies, sports and medical equipment,

rehabilitation equipment, in the form of handles and stands for industrial and household appliances, springs with a button are indispensable in work.

REFERENCE: Reduction is the process of reducing the diameter of a pipe through plastic deformation.

A radial press (crimping machine) is used for this purpose. The design of the machine allows you to adjust the degree of pipe compression with an accuracy of 0.1 mm,which makes it possible to obtain the required density of entry of a pipe of a smaller diameter into a pipe with a larger diameter on the samecomplete set of tools, at no additional cost.

In pipes of smaller and larger diameters, one is drilled at a distance of 20-40 mm from the edge, if a spring with one button is used,or two - in the case of using a spring with two buttons, a hole with a diameter of 0.1-0.2 mm larger than the diameter of the button of the spring used.

The spring is inserted into a pipe of smaller diameter, so that the button looks out of the hole.Next, a pipe with a larger diameter is put on a pipe of a smaller diameter. We press the spring button and press it down, aligning the holes of both pipes.

Attention!

Beware of cheap Chinese analogues! Low production quality, as well as the use of cheap raw materials in production, can lead to the destruction of the retainer at the most inopportune moment! Under prolonged static load, the spring plate will simply burst and your structural element will collapse, which can lead to quite unpleasant consequences.
