Description

Technical Field

[0001] This invention relates to the field of clamping technology, and specifically to a clamping fixture for fixing the edge of a roof safety net. Background Technology

[0002] In the construction industry, safety nets need to be installed below the work surface to prevent construction workers from falling from heights and building materials from falling.

[0003] Currently, most roof safety nets are secured using wire binding, a process that is not only cumbersome but also inefficient. Construction workers must manually wrap the wire and tie knots one by one, which is time-consuming and labor-intensive. Furthermore, the wire bindings are difficult to remove, easily damage the safety net, and hinder its reuse.

[0004] To address this, we propose a roof safety net edge fixing clamp. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a roof safety net edge fixing clamp.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a roof safety net edge fixing clamp, comprising multiple clamping blocks disposed between the steel profile and the edge of the safety net, including a snap-fit ​​mechanism, comprising multiple slots formed on the steel profile, a snap-fit ​​block fixed on the inner wall of the top of the clamping block and slidingly engaged with the adjacent slots for installing the clamping block on the steel profile, and a slider sliding inside the clamping block and abutting against the steel profile. The side of the clamping block away from the steel profile is provided with an installation block inserted into the mesh of the safety net for fixing the safety net on the clamping block. The clamping block is provided with a connecting mechanism for connecting the installation block. Through the operation of the above components, the safety net can be fixed on the steel profile.

[0007] Furthermore, the connecting mechanism includes a sliding groove on the top of the clamping block, a sliding block that slides inside the sliding groove, and a connecting block fixed between the sliding block and the clamping block. The side of the steel section closest to the safety net is provided with an insert block. The mounting block has a slot, and the insert block is slidably inserted into the slot. The mounting block has a threaded hole. The side of the clamping block away from the steel section is threadedly connected with a bolt that is threaded into the threaded hole to fix the mounting block on the clamping block. The insert block has multiple threaded holes, and the bolts are threadedly connected inside adjacent threaded holes. Through the operation of the above components, the installation method of the clamp can be easily adjusted by the construction personnel.

[0008] Furthermore, the length of the sliding block is greater than the length of the sliding groove opening, and the connecting block is slidably inserted into the sliding groove opening. By using a sliding block with a length greater than the length of the sliding groove opening, the sliding block can be prevented from sliding out of the sliding groove.

[0009] Furthermore, a fixing block is fixed to the inner wall of the top of the mounting block, and a loading groove is provided on the side of the fixing block near the mounting block. A limiting block for limiting the safety net inside the mounting block is hinged inside the loading groove. The edge of the safety net can be limited inside the mounting block by the limiting block.

[0010] Furthermore, a plurality of springs with their tail ends fixed to the inner wall of the top side of the mounting block are fixed on the side of the limiting block away from the steel profile for pushing the limiting block to reset deflection. Through the springs, the deflected limiting block can be pushed to reset deflection.

[0011] Furthermore, the end of the slider away from the profile steel is threaded with a threaded post that is rotatably connected inside the clamping block to drive the slider to make vertical displacement. The outer wall of the threaded post is threaded with a gear located below the slider. The outer side of the gear is meshed with a rack plate fixed on the mounting block to drive the gear to rotate. Through the operation of the above components, the slider can be driven to make vertical displacement.

[0012] Furthermore, the mounting block is an L-shaped block, and the clamping block is a concave block. The concave clamping block can be snapped onto the outside of the steel profile.

[0013] Furthermore, the clamping block is provided with a sliding groove, and the rack plate is slidably inserted into the sliding groove. Through the sliding groove, the clamping block can be prevented from interfering with the displacement of the rack plate.

[0014] Furthermore, the slot is a rectangular slot and the block is a rectangular block. By using slots and blocks, both of which are rectangular structures, the stability of the external clamping block of the steel profile can be improved.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention helps construction workers fix the edges of safety nets to steel profiles, avoiding the need for workers to manually wrap wires and tie knots one by one. It is easy to use, and the position of the clamps can be flexibly adjusted according to installation requirements, making it convenient for construction workers to fix the clamps to the steel profiles. The safety nets on the clamps can be confined, improving the stability of the safety nets on the clamps and ensuring high safety performance.

[0016] 2. The present invention allows for adjustment of the installation method of the clamps according to the installation environment. Multiple clamps can be quickly fixed to the steel profile, and individual clamps can also be fixed to the steel profile. The installation method is flexible, and it is convenient for construction personnel to remove the clamps from the steel profile and recycle the clamps, thus saving costs.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Combination Figure 1 and Figure 6 This embodiment of a roof safety net edge fixing clamp includes multiple clamping blocks 3 disposed between the edges of a steel profile 1 and a safety net 2. It includes a snap-fit ​​mechanism, including multiple slots 4 formed on the steel profile 1, a snap-fit ​​block 5 fixed on the inner wall of the top of the clamping block 3 and slidingly engaged with the adjacent slots 4 for mounting the clamping block 3 on the steel profile 1, and a slider 6 sliding inside the clamping block 3 and abutting against the steel profile 1. The side of the clamping block 3 away from the steel profile 1 is provided with an installation block 7 inserted into the mesh of the safety net 2 for fixing the safety net 2 on the clamping block 3. The clamping block 3 is provided with a connecting mechanism for connecting the installation block 7.

[0021] The implementation principle of the roof safety net edge fixing clamp in this embodiment is as follows: When it is necessary to fix the edge of the roof safety net to the steel section 1, the clamping block 3 can be clamped to the outside of the steel section 1, the clamping block 5 on the clamping block 3 is aligned with the slot 4, the clamping block 3 is pressed, and the clamping block 3 and the clamping block 5 on the clamping block 3 are moved vertically. When the clamping block 5 is inserted into the slot 4, the slider 6 is moved vertically. When the slider 6 abuts against the steel section 1, the clamping block 3 is fixed to the outside of the steel section 1. Then the mesh at the edge of the safety net 2 can be fitted onto the outside of the mounting block 7, and the safety net 2 is fixed to the steel section 1.

[0022] Example 2: Combination Figure 2 , Figure 3 , Figure 4 and Figure 5 This embodiment, based on embodiment 1, further improves upon the following: the connecting mechanism includes a sliding groove 12 on the top of the clamping block 3, a sliding block 13 sliding inside the sliding groove 12, and a connecting block 14 fixed between the sliding block 13 and the clamping block 3. A plug 19 is provided on the side of the steel profile 1 closest to the safety net 2. A slot 18 is provided on the mounting block 7, and the plug 19 is slidably inserted into the slot 18. A threaded hole 21 is provided on the mounting block 7. A bolt 20, threadedly engaged with the threaded hole 21, is provided on the side of the clamping block 3 away from the steel profile 1 to fix the mounting block 7 onto the clamping block 3. Multiple threaded holes 22 are provided on the plug 19, and the bolt 20 is threadedly connected to adjacent threaded holes 22. A threaded post 15, rotatably connected inside the clamping block 3, is threaded through the end of the slider 6 away from the steel profile 1 to drive the slider 6 to make vertical displacement. A gear 16 located below the slider 6 is threadedly sleeved on the outer wall of the threaded post 15. A gear 16 meshes with a fixed part on the outer side of the gear 16. The rack plate 17 on the mounting block 7 is used to drive the gear 16 to rotate. When it is necessary to install the clamping block 3 on the outside of the steel profile 1, the corresponding number of clamping blocks 3 can be inserted into the outside of the insert block 19 according to the installation requirements. Then, the corresponding number of clamping blocks 3 are snapped into the outside of the steel profile 1. The snapping block 5 on the clamping block 3 is aligned with the snapping slot 4. The clamping block 3 is pressed, which drives the clamping block 3 and the snapping block 5 on the clamping block 3 to move vertically. When the snapping block 5 is inserted into the snapping slot 4, the mounting block 7 is pushed, which drives the mounting block 7 to move, drives the rack plate 17 to move, drives the gear 16 to rotate, drives the threaded column 15 to rotate, and drives the slider 6 to move vertically through the threaded engagement of the threaded column 15 and the slider 6. When the slider 6 abuts against the steel profile 1, the mounting block 7 has a threaded hole 21. The bolt 20 is passed through the threaded hole 21 on the mounting block 7 and through the threaded holes 22 located at both ends of the insert block 19, and screwed into the inside of the clamping block 3. At this time, the clamping block 3 is fixed to the outside of the steel profile 1.

[0023] When construction workers need to install a small number of clamping blocks 3 on the outside of the steel profile 1 during the installation of clamping blocks 3, they can directly clamp a single clamping block 3 onto the outside of the steel profile 1, align the clamping block 5 on the clamping block 3 with the slot 4, press the clamping block 3, and drive the clamping block 3 and the clamping block 5 on the clamping block 3 to move vertically. When the clamping block 5 is inserted into the slot 4, push the mounting block 7, drive the mounting block 7 to move, drive the rack plate 17 to move, drive the gear 16 to rotate, drive the threaded column 15 to rotate, and through the threaded engagement between the threaded column 15 and the slider 6, drive the slider 6 to move vertically. When the slider 6 abuts against the steel profile 1, the clamping block 3 is fixed to the outside of the steel profile 1. Then, screw the bolt 20 through the threaded hole 21 on the mounting block 7 into the inside of the clamping block 3, and the clamping block 3 is fixed to the outside of the steel profile 1.

[0024] The length of the sliding block 13 is greater than the length of the groove opening of the sliding groove 12. The connecting block 14 is slidably inserted into the groove opening of the sliding groove 12. By using the sliding block 13, which is longer than the length of the groove opening of the sliding groove 12, the sliding block 13 can be prevented from sliding out of the sliding groove 12.

[0025] Example 3: Combination Figure 7 This embodiment is further improved on the basis of embodiment 1 as follows: a fixing block 8 is fixed to the inner wall of the top of the mounting block 7. A loading groove 9 is opened on the side of the fixing block 8 near the mounting block 7. A limiting block 10 for limiting the safety net 2 inside the mounting block 7 is hinged inside the loading groove 9. Multiple springs 11 with their tails fixed to the inner wall of the top side of the limiting block 7 for pushing the limiting block 10 to reset and deflect. When it is necessary to attach the edge of the safety net 2 to the outside of the mounting block 7, the mesh of the edge of the safety net 2 can be placed on the outside of the mounting block 7 and the limiting block 10. Pulling the safety net 2 will cause the limiting block 10 to deflect. When the mesh of the safety net 2 is inside the mounting block 7, the spring 11 pushes the deflected limiting block 10 to reset. At this time, the edge of the safety net 2 is installed inside the mounting block 7.

[0026] The mounting block 7 is an L-shaped block, and the clamping block 3 is a concave block. The clamping block 3 with its concave structure can be snapped onto the outside of the steel section 1.

[0027] The clamping block 3 has a sliding groove, and the rack plate 17 is slidably inserted into the sliding groove. The sliding groove can prevent the clamping block 3 from interfering with the displacement of the rack plate 17.

[0028] The slot 4 is a rectangular slot, and the block 5 is a rectangular block. By using the slot 4 and the block 5, which are both rectangular structures, the stability of the external clamping block 3 of the steel profile 1 can be improved.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
