[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0031] Refer to Figure 1 - Figure 3 In one embodiment provided by the present utility model: An installation mechanism for a square pipe fastener includes a pipe fitting 1, which serves as a basic structure and provides an installation position for nuts and fixed columns 2. Nuts are provided on the inner wall of the pipe fitting 1 and cooperate with bolt 1 5 to fix the square pipe fastener 3. A fixed column 2 is fixedly connected to the front side of the pipe fitting 1 and cooperates with the square pipe fastener 3 to improve the stability of the square pipe fastener 3. A square pipe fastener 3 is provided on the front side of the pipe fitting 1, and two groups of aluminum alloy cross bars 4 are provided thereon. The left group of aluminum alloy cross bars 4 is arranged at an angle of 45 degrees. The aluminum alloy cross bar 4 is fixedly installed on the front side of the square pipe fastener 3 through bolt 2. A bolt 1 5 is provided on the inner wall of the front side of the square pipe fastener 3, and the nut cooperates with bolt 1 5 to fix the square pipe fastener 3.
[0032] Furthermore, a fixing component is provided on the inner wall of the square pipe fastener 3. The fixing component includes a moving plate 51, which moves forward under extrusion during the tightening process of bolt 1 5, driving the rear extrusion plate 53 and card plate 54 to move, realizing the clamping and fixing with the fixed column 2. The moving plate 51 is slidably connected to the inner wall of the square pipe fastener 3. The rear side of the moving plate 51 is elastically connected to the square pipe fastener 3 through a compression spring 52, providing an elastic restoring force forward for the moving plate 51. The rear side of the moving plate 51 is fixedly connected to an extrusion plate 53, whose function is to push the card plate 54 towards the card slot 56 when the moving plate 51 moves, realizing the clamping with the fixed column 2.
[0033] Refer toFigure 2 And Figure 3 , a clamping plate 54 is slidably connected to the rear side of the extrusion plate 53. Under the push of the extrusion plate 53, it is inserted into the card slot 56 of the fixing column 2, realizing the fixed connection between the square pipe fastener 3 and the pipe fitting 1. A slot 55 is opened at the rear side of the square pipe fastener 3 for inserting the fixing column 2. The fixing column 2 is inserted into the inner wall of the slot 55. There are two groups of fixing columns 2. A card slot 56 is opened on the opposite side of the two groups of fixing columns 2, which can cooperate with the clamping plate 54 to further fix the square pipe fastener 3 and improve its stability. The clamping plate 54 is inserted into the inner wall of the card slot 56. There are two groups of compression springs 52, extrusion plates 53 and clamping plates 54. The two groups of compression springs 52, extrusion plates 53 and clamping plates 54 are symmetrically arranged with the center line of the moving plate 51 as the axis of symmetry, which is used to improve the stability of the fixation. The contact surface between the extrusion plate 53 and the clamping plate 54 is set as an inclined surface, which is convenient for converting the horizontal movement of the moving plate 51 into the vertical movement of the clamping plate 54.
[0034] Refer to Figure 1 And Figure 4 , an anti-loosening component is arranged on the inner wall of the square pipe fastener 3. The anti-loosening component includes a limit groove 61 and a limit plate 62 for cooperation to prevent the first bolt 5 from loosening. The limit groove 61 is opened on the outer side of the first bolt 5. A limit plate 62 is slidably connected to the inner wall of the square pipe fastener 3. When the first bolt 5 is tightened, it is inserted into the limit groove 61 to prevent the first bolt 5 from loosening. The bottom end of the limit plate 62 is elastically connected to the square pipe fastener 3 through a return spring 63, providing an upward elastic restoring force for the limit plate 62. When the first bolt 5 loosens, it pushes the limit plate 62 to move upward, so that the limit plate 62 maintains a clamped state with the limit groove 61 to prevent the first bolt 5 from loosening. A baffle is fixedly connected to the front side of the limit plate 62 close to the return spring 63. The baffle is slidably connected to the inner wall of the square pipe fastener 3. The baffle can prevent impurities from entering and affecting the normal operation of the return spring 63. The limit plate 62 is set in an L shape for convenient operation.
[0035] Working principle: When in use, the first bolt 5 is passed through the square pipe fastener 3 and screwed into the nut on the inner wall of the pipe fitting 1. As the first bolt 5 is gradually tightened, the end of the first bolt 5 begins to press the moving plate 51 on the inner wall of the square pipe fastener 3. The moving plate 51 moves forward, driving the compression spring 52 to be compressed. At the same time, it drives the extrusion plate 53 to move together with the moving plate 51. Due to the contact surface between the extrusion plate 53 and the clamping plate 54 being set as an inclined surface, when the extrusion plate 53 moves, it pushes the clamping plate 54 to move to both sides, so that the clamping plate 54 is clamped with the card slot 56 on the fixing column 2, realizing the further fixation of the square pipe fastener 3 and the pipe fitting 1.
[0036] When the bolt 5 is tightened to a certain extent, the limit plate 62 is inserted into the limit groove 61 under the action of the elastic restoring force of the return spring 63, which can prevent the bolt 5 from loosening during use. The limit plate 62 will always maintain the clamped state with the limit groove 61 under the push of the return spring 63, thereby preventing the bolt 5 from loosening.
[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
