Description

Technical Field

[0001] The utility model relates to the technical field of square tubes, in particular to a high-strength square tube with high toughness. Background Art

[0002] Square tube is a name for square tube and rectangular tube, that is, tube with equal and unequal side lengths. There are many square tubes of various profiles on the market, such as plastic square tube and steel square tube. For current plastic square tubes, they are divided into two categories: thermoplastic plastic tube and thermosetting plastic tube. Thermoplastic ones include polyvinyl chloride tube, polyethylene tube, polypropylene tube, polyoxymethylene tube, etc., and thermosetting ones include phenol plastic tube, etc. They are generally used in some ventilation ducts to play the role of ventilation ducts.

[0003] When connecting the rectangular square tubes of the transmission, screws are generally used to connect two adjacent tube bodies. With this connection method, the connection speed is slow and various tools are required, which is troublesome to operate. In addition, after the existing plastic square tube is connected to the mounting frame, it is easy to cause the tube body to vibrate during ventilation. This force directly acts on the mounting frame. Especially when the installation is loose, the two are in hard contact, which can easily cause damage to the tube body. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a high-strength square tube with high toughness. The square tube can be protected by a rubber ring to ensure its actual toughness. In addition, compared with the prior art, the installation and disassembly are relatively convenient.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A high-strength square tube with very high toughness comprises a square tube body, a first connecting ring is fixedly connected to the left side of the square tube body, a second connecting ring is fixedly connected to the right side of the square tube body, and a rectangular groove is provided on the right side of each of the first connecting rings; a limiting mechanism, the limiting mechanism comprises two through-holes penetrating the upper end of the second connecting ring, each of the through-holes is penetrated by a vertical bar, the upper ends of the two vertical bars are fixedly connected to a transverse bar, and the lower ends of the two transverse bars are fixedly connected to the upper end of the second connecting ring through a plurality of springs; a protective mechanism, the protective mechanism is located on the outer side of the square tube body.

[0007] Preferably, the first connecting ring and the second connecting ring are both rectangular rings.

[0008] Preferably, the upper end of the second connecting ring is symmetrically fixedly connected with two slots.

[0009] Preferably, each of the slots cooperates with a corresponding vertical bar.

[0010] Preferably, the protection mechanism comprises a plurality of annular grooves formed on the outer side of the square tube body, and a rectangular ring is disposed on the outer side of each of the annular grooves.

[0011] Preferably, each of the rectangular rings is a rubber ring.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] Springs, transverse bars and vertical bars are provided. When installing and disassembling, the operation can be completed by pulling the transverse bar and then loosening the transverse bar. Compared with the prior art, the operation is more convenient and does not require any tools, which improves the convenience of disassembly and installation. In addition, a rectangular ring is provided. When the square tube body vibrates subsequently, the force generated will be buffered by the rectangular ring and then transmitted to the mounting frame, reducing the interaction force and improving the toughness of the square tube body. Since the rubber ring itself has greater elasticity, it can be easily replaced even if it is damaged alone. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0020] Reference Figure 1-Figure 3A high-strength square tube with high toughness comprises a square tube body 1, the square tube body 1 is made of plastic, a first connecting ring 2 is fixedly connected to the left side of the square tube body 1, and a second connecting ring 3 is fixedly connected to the right side of the square tube body 1. A rectangular groove 6 is provided on the right side of each first connecting ring 2, and the first connecting ring 2 and the second connecting ring 3 are both rectangular rings;

[0021] Among them, it also includes a limiting mechanism, which includes two through-holes 11 penetrating the upper end of the second connecting ring 3, each through-hole 11 is penetrated by a vertical bar 5, the upper ends of the two vertical bars 5 are fixedly connected to a horizontal bar 4, the lower ends of the two horizontal bars 4 are fixedly connected to the upper end of the second connecting ring 3 through a plurality of springs 7, and the upper end of the second connecting ring 3 is symmetrically fixedly connected to two slots 10, each slot 10 is matched with the corresponding vertical bar 5;

[0022] It also includes a protection mechanism, which is located on the outside of the square tube body 1. The protection mechanism includes a plurality of annular grooves 8 opened on the outside of the square tube body 1. A rectangular ring 9 is arranged on the outside of each annular groove 8, and each rectangular ring 9 is a rubber ring.

[0023] In the utility model, when the two square tube bodies 1 need to be connected during use, it is only necessary to first pull the horizontal bar 4 upward to stretch the spring 7, and the horizontal bar 4 will drive the two vertical bars 5 upward to move away from the two slots 10. At this time, the first connecting ring 2 of the other square tube can be inserted into the corresponding rectangular groove 6, and then the horizontal bar 4 can be loosened. The horizontal bar 4 will move downward and drive the vertical bars 5 to be inserted into the slots 10 to complete the limit. When disassembly is required, it is only necessary to move the horizontal bar 4 upward to release the limit, and the two square tube bodies 1 can be separated. Compared with the prior art, the efficiency of disassembly and installation is effectively improved.

[0024] In addition, by using the rectangular ring 9, when the square tube body 1 is installed on the mounting frame, it is only necessary to make the mounting frame contact and connect with the rectangular ring 9. In this way, even if the tube body vibrates later, the generated force will be buffered by the rectangular ring 9 and then transmitted to the mounting frame, thereby reducing the interaction force and improving the toughness of the square tube body 1.

[0025] It should be noted that the rectangular ring 9 is a rubber ring with good elasticity, so when the rectangular ring 9 is damaged, the staff can replace it separately.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
