Description

Technical Field

[0001] The utility model relates to the technical field of the assembly and processing of hexagonal self-drilling chain screws, specifically to a hexagonal self-drilling chain belt. Background Technique

[0002] With the acceleration of the modern industrialization process, the performance requirements for fasteners are constantly increasing. As a fastener with a special structure and powerful functions, the hexagonal self-drilling screw is widely used in various occasions due to its good fixing effect, strong adhesion, high safety factor and other advantages. However, the traditional single-shot hexagonal self-drilling screw needs to be installed one by one during use, which not only has low efficiency but also increases the labor cost. To overcome this problem, the chain belt of the hexagonal self-drilling screw came into being.

[0003] The chain belt of the hexagonal self-drilling screw realizes the function of continuous installation by connecting multiple hexagonal self-drilling screws with a special nail belt. This innovative design greatly improves the construction efficiency, reduces the labor intensity, and at the same time reduces the problem of screws being scattered and lost. Specifically, the chain belt of the hexagonal self-drilling screw adopts an integrated design concept, connecting multiple hexagonal self-drilling screws together through a precise mechanical structure to form a compact and easy-to-operate chain belt.

[0004] However, most of the existing chain belts are used in cooperation with a nail gun. After the nail gun completes the fixation of the screw, due to the ejection of the screw, the bottom limit position of the screw on the chain belt will be irreversibly damaged, making the chain belt unable to be reused. In the long run, this will cause a large amount of resource waste and increase the long-term use cost. Content of the Utility Model

[0005] The purpose of the utility model is to provide a hexagonal self-drilling chain belt to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the hexagonal self-drilling chain belt provided by the utility model includes a retaining block. A circular through groove is opened at the middle position of the top surface of the retaining block. Two arc-shaped retaining pieces are fixedly installed on the bottom surface of the retaining block. An installation block is arranged at the bottom end of the retaining block. A limiting sleeve is installed at the bottom of the installation block. A guiding limiting column is arranged on the side of the arc-shaped retaining piece close to the limiting sleeve. A return spring is arranged between the limiting sleeve and the arc-shaped retaining piece.

[0007] Furthermore, an installation groove is opened on the side wall of the arc-shaped retaining piece close to the limiting sleeve, and the guiding limiting column is fixedly installed on the side wall of the installation groove.

[0010] Further, a plurality of limiting pieces are fixedly installed on the top surface of the retaining block. The plurality of limiting pieces are arranged in a circumferential array, and the specific materials of the plurality of limiting pieces and the limiting sleeve are both thermoplastic polyurethane.

[0011] Further, the guiding limiting post is adapted to the limiting sleeve. In the initial state, the guiding limiting post is inside the limiting sleeve.

[0012] Further, the chain belt is composed of a plurality of retaining blocks. A first docking piece is fixedly installed on the side wall of the retaining block at one side edge position, and a second docking piece is fixedly connected to the side wall of the retaining block at the other side edge position.

[0013] Further, a plugging groove is formed on the top surface of the first docking piece, a cylinder is fixedly installed on the top surface of the second docking piece, and a rotatable plugging limiting block is installed on the top surface of the cylinder. The plugging limiting block is adapted to the plugging groove.

[0025] Embodiment 1

[0026] Refer to Figures 1-4 , a hexagonal drill tail chain belt, including a retaining block 6, a circular through slot 7 is opened in the middle position of the top surface of the retaining block 6, two arc-shaped retaining pieces 10 are fixedly installed on the bottom surface of the retaining block 6, an installation block 9 is arranged at the bottom end of the retaining block 6, a limit sleeve 11 is installed at the bottom of the installation block 9, a guide limit post 13 is arranged on one side of the arc-shaped retaining piece 10 close to the limit sleeve 11, and a return spring 14 is arranged between the limit sleeve 11 and the arc-shaped retaining piece 10.

[0027] Furthermore, a mounting groove 12 is opened on the side wall of the arc-shaped retaining piece 10 on the side close to the limiting sleeve 11, and the guide limiting column 13 is fixedly installed on the side wall of the mounting groove 12. By setting the mounting groove 12 and setting the guide limiting column 13 fixedly installed on the side wall of the mounting groove 12, the installation of the guide limiting column 13 is more stable and simple. One end of the reset spring 14 is fixedly connected to the side wall of the limiting sleeve 11, and the other end is fixedly connected to the side wall of the mounting groove 12. By setting the two ends of the reset spring 14 to connect the limiting sleeve 11 and the side wall of the mounting groove 12 respectively, the reset spring 14 will be compressed when the arc-shaped retaining piece 10 approaches the limiting sleeve 11, and will be reset by the elastic force of the reset spring 14 after the pressure is lost.

[0028] Furthermore, the guide limit post 13 is adapted to the limit sleeve 11, and in the initial state, the guide limit post 13 is located inside the limit sleeve 11. By setting the guide limit post 13 to be adapted to the limit sleeve 11, and setting the guide limit post 13 to be located inside the limit sleeve 11 in the initial state, the arc-shaped retaining plate 10 is limited by the guide limit post 13 and the limit sleeve 11 when being interfered, and can only move in a fixed direction.

[0029] In addition, clamping blocks 15 are fixedly installed on the inner walls of the two arc-shaped retaining plates 10, and the edge positions of the clamping blocks 15 are provided with rounded corners. By providing the edge positions of the clamping blocks 15 with rounded corners, the hexagonal drill screws can pass through the clamping blocks 15 more smoothly without causing excessive damage to the arc-shaped retaining plates 10 and the clamping blocks 15.

[0030] A plurality of limit plates 8 are fixedly installed on the top surface of the retaining block 6, and the plurality of limit plates 8 are arranged in a circular array. The specific material of the plurality of limit plates 8 and the limit sleeve 11 are thermoplastic polyurethane. By setting a plurality of limit plates 8, and setting the specific material of the plurality of limit plates 8 to be thermoplastic polyurethane, the edge position of the nut of the hexagonal self-drilling screw cannot be easily detached after passing through the plurality of limit plates 8, thereby realizing bidirectional limiting of the hexagonal self-drilling screw.

[0031] During specific implementation, the user needs to first place the hexagonal drill screw in the circular through groove 7. When the hexagonal drill screw is in the circular through groove 7, it is limited by the limiting plate 8, the arc-shaped retaining plate 10 and the clamping block 15 so that the hexagonal drill screw will not move easily. After the placement is completed, the user can use the chain belt in conjunction with the nail gun. When the nail gun pushes the hexagonal drill screw out from the bottom of the retaining block 6, the largest part of the hexagonal drill screw will push the two arc-shaped retaining plates 10 to both sides.

[0032] Under normal conditions, the arc-shaped retaining piece 10 is mostly fixedly connected, and directly loses its original limiting effect after the hexagonal self-drilling screw passes through, and cannot be reused.

[0033] In this utility model, when the two arc-shaped retaining pieces 10 are pushed against and moved to both sides, they will drive the guiding and limiting posts 13 to move inside the limiting sleeves 11, and during the movement, the return springs 14 are compressed. After the hexagon drill tail screw passes through the arc-shaped retaining pieces 10, the two return springs 14 are reset simultaneously, which can push the arc-shaped retaining pieces 10 back to their original positions, so that the two arc-shaped retaining pieces 10 can still limit and fix the new hexagon drill tail screw, thereby realizing the reuse of the retaining block 6.

[0034] By setting the arc-shaped retaining pieces 10, the limiting sleeves 11, the guiding and limiting posts 13 and the return springs 14, the retaining block 6 can be reused. Through repeated use, the consumption of new materials is reduced, which helps to save resources, avoids the cost of frequently purchasing new chain belts, reduces the long-term use cost, reduces the generation of waste, conforms to the environmental protection concept, and helps to achieve sustainable development.

[0035] Embodiment 2

[0036] On the basis of Embodiment 1, please refer to Figures 1-4 , the hexagon drill tail chain belt, wherein the chain belt is composed of a plurality of retaining blocks 6. A first docking piece 1 is fixedly installed on the side wall of the retaining block 6 at one side edge position, and a second docking piece 2 is fixedly connected to the side wall of the retaining block 6 at the other side edge position. A plugging groove 3 is formed on the top surface of the first docking piece 1, a cylinder 4 is fixedly installed on the top surface of the second docking piece 2, and a rotatable plugging limiting block 5 is installed on the top surface of the cylinder 4. The plugging limiting block 5 is adapted to the plugging groove 3.

[0037] During specific implementation, during the use of the chain belt, it is often necessary to use the chain belt for a long time. At this time, a single chain belt cannot meet the use requirements. During the long-term use process, it is necessary to frequently replace the chain belt to complete the continuous use of the chain belt.

[0038] In this utility model, the user can align the first docking piece 1 and the second docking piece 2 of the two chain belts. After alignment, insert the plugging limiting block 5 into the plugging groove 3, and then rotate the plugging limiting block 5 to complete the connection of the two sections of the chain belt. Using this method, the user can quickly complete the connection between the chain belts and can also freely determine the number of connections.

[0039] By setting the first docking piece 1, the second docking piece 2, the plugging groove 3 and the plugging limiting block 5, the two sections of the chain belt can be quickly spliced, so that the chain belt can meet different use conditions and increases the applicable range of the chain belt.

[0040] Working principle: the user needs to place the hexagonal self-drilling screw into the circular through groove 7 first. When the hexagonal self-drilling screw is in the circular through groove 7, it is limited by the limiting piece 8, the arc-shaped retaining piece 10 and the clamping block 15 so that the hexagonal self-drilling screw will not move easily. After the placement is completed, the user can use the chain belt in conjunction with the nail gun. When the nail gun pushes the hexagonal self-drilling screw out from the bottom of the retaining block 6, the largest part of the hexagonal self-drilling screw will push the two arc-shaped retaining pieces 10 to both sides.

[0041] Under normal conditions, the arc-shaped retaining piece 10 is mostly fixedly connected, and directly loses its original limiting effect after the hexagonal self-drilling screw passes through, and cannot be reused.

[0042] In the present invention, after the two arc-shaped retaining plates 10 are resisted and moved to both sides, they will drive the guide limit column 13 to move inside the limit sleeve 11, and compress the reset spring 14 during the movement. After the hexagonal self-drilling screw passes through the arc-shaped retaining plate 10, the two reset springs 14 are reset at the same time to push the arc-shaped retaining plate 10 to reset, so that the two arc-shaped retaining plates 10 can still form a limit fixation for the new hexagonal self-drilling screw, thereby realizing the reuse of the retaining block 6.

[0043] During the use of the chain belt, it is often necessary to use the chain belt for a long time. At this time, the chain belt alone cannot meet the use needs. During long-term use, the chain belt needs to be replaced frequently to complete the continuous use of the chain belt.

[0044] In the present invention, the user can align the first docking piece 1 and the second docking piece 2 of the two chain belts, and then insert the plug-in limit block 5 into the plug-in slot 3, and then rotate the plug-in limit block 5 to complete the connection of the two chain belts. In this way, the user can quickly complete the connection between the chain belts and can freely decide the number of connections.

[0045] By providing an arc-shaped retaining plate 10, a limiting sleeve 11, a guide limiting column 13 and a return spring 14, the retaining block 6 can be reused. Through reuse, the consumption of new materials is reduced, which helps to save resources, avoids the cost of frequent purchase of new chain belts, reduces the cost of long-term use, reduces waste generation, complies with environmental protection concepts, and contributes to sustainable development.

[0046] By providing the first butt joint piece 1, the second butt joint piece 2, the plug-in groove 3 and the plug-in limit block 5, the two sections of the chain belt can be quickly spliced, so that the chain belt can meet different usage conditions and the application range of the chain belt is increased.

[0047] The above are only the preferred embodiments of the present utility model, and do not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with the preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present utility model, may make some changes or modifications using the technical content prompted above as equivalent embodiments of equivalent changes. The implementation schemes in the above embodiments can also be further combined or replaced. However, as long as the content does not depart from the technical solution of the present utility model, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still fall within the scope of the present utility model's solution.
