[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0029] According to an embodiment of the present invention, a seat belt securing device is provided, comprising:

[0030] The first mounting component 1 and the second mounting component 2 are detachably fastened to form a snap-fit ​​space at the intersection of the steel mesh.

[0031] The suspension component 3 is mounted on the first mounting component 1 or the second mounting component 2, and the suspension component 3 is provided with a buckle part suitable for hanging a safety belt.

[0032] The safety belt fixing device provided in this embodiment uses aluminum alloy for both the first mounting component 1 and the second mounting component 2. These components can be detachably fastened to form a locking space at the intersection of the reinforcing mesh. Compared to the traditional method of fixing to a single reinforcing bar at a single point, this device utilizes the multi-dimensional constraint characteristics of the reinforcing mesh intersection nodes to increase the contact area and friction, effectively preventing the device from sliding, rotating, or disengaging under external impact or vibration conditions, significantly improving stability. Simultaneously, it distributes the load to multiple nodes of the reinforcing mesh, avoiding concentrated stress at a single point, reducing the risk of reinforcing bar deformation, enhancing support capacity, and reducing displacement under dynamic loads. Furthermore, this device is adaptable to reinforcing mesh structures, compatible with reinforcing bars of different diameters without frequent component replacements, solving the problem of limited adaptability in existing devices and providing more reliable safety protection for workers operating at heights.

[0033] Furthermore, the first mounting component 1 is provided with two intersecting snap-fit ​​grooves, which are connected to form a rebar receiving area; the second mounting component 2 is provided with a snap-fit ​​plate that cooperates with the snap-fit ​​groove. When the first mounting component 1 and the second mounting component 2 are fastened together, the snap-fit ​​plate is embedded in the snap-fit ​​groove, together forming a snap-fit ​​space suitable for snapping rebar.

[0034] In simple terms, the intersecting slots and corresponding clamping plates form a clamping space that precisely wraps around the two reinforcing bars at the intersection of the steel mesh. Utilizing the perpendicular constraint of the reinforcing bars, the stability of the device is enhanced, effectively resisting slippage and rotation caused by external forces. This allows the load to be evenly distributed across the two reinforcing bars, reducing the stress on a single bar, further increasing support strength, and minimizing the risk of reinforcing bar deformation. Simultaneously, this structure has excellent compatibility with reinforcing bars of different thicknesses, adapting to various specifications without additional adjustments. This improves the versatility and installation efficiency of the device, simplifies on-site operations, and provides reliable safety assurance for high-altitude operations.

[0035] In an optional embodiment, an elastic clamp structure can be used as the first mounting component 1. The clamp is made of a flexible material with elasticity and tightens the intersection of the steel mesh through elastic contraction force. Adjustable fastening bolts are provided on the clamp, which can not only adapt to steel bars of different sizes, but also adjust the tightening force according to actual needs, thus increasing the flexibility of use.

[0036] Furthermore, the cross-section of the snap-fit ​​groove is U-shaped, the opening end of the snap-fit ​​groove is provided with a guide slope, and the edge of the snap-fit ​​plate is provided with a wedge-shaped part that cooperates with the guide slope.

[0037] It should be noted that the snap-fit ​​groove adopts a U-shaped cross-section design, which can closely fit the cylindrical surface of the reinforcing bar, increasing the contact area and thus improving friction, effectively preventing the device from sliding on the reinforcing bar and enhancing the stability of the fixation. The guide slope at the opening end of the snap-fit ​​groove cooperates with the wedge-shaped part of the edge of the snap-fit ​​plate. When the first mounting part 1 and the second mounting part 2 are engaged, the guide slope can guide the snap-fit ​​plate to quickly and accurately embed into the snap-fit ​​groove, significantly reducing installation difficulty and greatly improving installation efficiency. At the same time, the wedge-shaped part and the guide slope fit tightly together to form a wedge-shaped locking structure, making the connection between the snap-fit ​​plate and the snap-fit ​​groove more secure. Under external impact or vibration, it can also effectively prevent the snap-fit ​​plate from accidentally coming off, further ensuring the reliability of the safety belt fixing device and providing safer protection for workers at heights.

[0038] Furthermore, the axes of the two snap-fit ​​grooves are orthogonally set at 90° to form a cross-shaped snap-fit ​​structure, and the minimum inner diameter of the rebar accommodating area is adapted to the diameter of the rebar.

[0039] Intuitively, the cross-shaped locking structure formed by the two locking groove axes set at 90° orthogonal angles can precisely lock the two reinforcing bars at the intersection of the reinforcing mesh. This bidirectional constraint significantly improves the anti-slip and anti-rotation capabilities of the fixing device, enhancing stability under complex external forces compared to unidirectional fixing methods. The minimum inner diameter of the reinforcing bar accommodating area matches the diameter of the reinforcing bar, ensuring a tight fit between the device and the reinforcing bar. This avoids wobbling caused by excessive gaps and prevents excessive compression that could damage the reinforcing bar. It effectively distributes the load applied by the operator, reduces the risk of reinforcing bar deformation, and ensures fixing strength. The locking plate of the second mounting component 2 is also cross-shaped, fitting perfectly over the cross-shaped locking structure.

[0040] Furthermore, the first mounting component 1 is provided with a first locking hole 11, and the second mounting component 2 is provided with a second locking hole 21, the first locking hole 11 and the second locking hole 21 are coaxially arranged; it also includes a locking component, which passes through the first locking hole 11 and the second locking hole 21 and locks thereafter, so as to realize the detachable connection between the first mounting component 1 and the second mounting component 2.

[0041] It should be noted that during installation, workers only need to quickly insert the locking piece into the two holes to complete the connection and fixation of the installation components, improving installation efficiency and shortening construction time. In terms of connection stability, after the locking piece is fully engaged, it provides strong axial tensile force, effectively preventing accidental separation of the first and second installation components during use. This ensures stable clamping of the reinforcing steel bars within the locking space, enhancing the overall reliability of the safety belt fixing device and protecting the safety of workers operating at heights.

[0042] Furthermore, four first locking holes 11 and four second locking holes 21 are symmetrically arranged at the intersection of the cross-shaped locking structure.

[0043] It is easy to understand that the symmetrically distributed first locking hole 11 and second locking hole 21 make the locking member uniformly stressed, which can evenly disperse the tensile force generated by the first and second mounting parts, avoid local stress concentration, enhance the overall stability of the snap-fit ​​structure, and effectively prevent the device from loosening or deforming when subjected to external impact or vibration.

[0044] Of course, in other embodiments, two, three, or more first locking holes 11 and second locking holes 21 may be provided to achieve stable fixing of the device. Here, the number of first locking holes 11 and second locking holes 21 is not limited.

[0045] Furthermore, the locking element is a bolt.

[0046] Intuitively, bolted connections allow for precise control of tightening force by rotating the nut, and the clamping degree can be flexibly adjusted according to factors such as rebar specifications and working environment, ensuring that the first and second installation parts fit tightly against the rebar mesh, effectively enhancing the stability of the snap-fit ​​structure; its thread self-locking characteristic can prevent the locking parts from loosening under vibration conditions at the construction site, ensuring the long-term reliable operation of the device.

[0047] In an alternative embodiment, a pin can be used as a locking element. After the pin is inserted into the first locking hole 11 and the second locking hole 21 of the coaxial cable, it is limited by an elastic snap ring or a cotter pin to prevent the pin from coming out. This method allows for rapid installation and is suitable for emergency construction scenarios where high installation efficiency is required.

[0048] Furthermore, the four first locking holes 11 and the four second locking holes 21 are arranged in a circular array with the center of the cross-shaped snap-fit ​​structure as the center, and the central angle between two adjacent first locking holes 11 or two adjacent second locking holes 21 is 90°.

[0049] Furthermore, a fixing part 22 is provided on the side of the second mounting member 2 away from the first mounting member 1, and the suspension member 3 is a rod-type suspension member, which is suitable for insertion into the fixing part 22.

[0050] The plug-in method is simple and quick, allowing construction workers to quickly connect the suspension component 3 to the second installation component 2 without the need for complicated tools, thus improving installation efficiency. The fixing part 22 works closely with the pole-type suspension component to effectively limit the swaying and displacement of the suspension component 3, ensuring that the load is smoothly transferred to the fixing device and steel mesh when the safety belt is under force, thus ensuring the safety of high-altitude operations.

[0051] Specifically, the fixing part 22 and the second mounting part 2 can be integrally formed or welded together. The fixing part is cylindrical with an inner diameter slightly larger than the outer diameter of the rod-type suspension part to facilitate insertion. Preferably, the suspension part 3 is a 48.3*3.6 steel pipe.

[0052] In an optional embodiment, the suspension member 3 can be configured as a hook-type suspension member 3. Construction workers only need to align the hook with the hanging point of the fixing part 22 to easily complete the connection. The operation is extremely simple and can effectively shorten the installation time, making it particularly suitable for construction scenarios requiring emergency installation.

[0053] Furthermore, the fixing part 22 is provided with a first connecting hole 23, and the rod-type suspension member is provided with a second connecting hole 31; it also includes a connector, which, when the rod-type suspension member is inserted into the fixing part 22, passes through the first connecting hole 23 and the second connecting hole 31 and locks in place, so as to realize the detachable connection between the fixing part 22 and the rod-type suspension member.

[0054] It is easy to understand that both the first connecting hole 23 and the second connecting hole 31 are located near the bottom, preferably 4 cm from the bottom. The fixing part 22 and the rod-type suspension member are detachably connected through the first connecting hole 23, the second connecting hole 31, and the connector. After the connector is locked through, it can effectively restrict the axial movement and circumferential rotation of the rod-type suspension member within the fixing part 22. Compared with a simple plug-in structure, it greatly enhances the connection strength, ensuring that the suspension member 3 remains stable and does not loosen even when the worker makes large movements or is subjected to external impact, thus ensuring the reliable load-bearing capacity of the safety belt.

[0055] In an optional embodiment, a threaded connection can be used to connect the fixing part 22 and the rod-type suspension member. An internal thread is provided on the inner cavity surface of the fixing part 22, and an external thread is provided on the outer peripheral surface of the rod-type suspension member. The rod-type suspension member is rotated to screw into the fixing part 22, and a firm connection is achieved by utilizing the self-locking property of the thread.

[0056] Furthermore, the connector is a bolt.

[0057] As is easily understood, the bolt, through the tightening of the nut, can provide a strong and adjustable fastening force. Construction personnel can precisely adjust the tightening degree according to the actual working conditions to ensure that the rod-type suspension component and the fixed part 22 are tightly connected, effectively resisting external forces such as vibration and impact during high-altitude operations, and improving the stability of the connection.

[0058] In an optional embodiment, a pin can be used as the connector. A cylindrical pin or a conical pin is inserted into the first connecting hole 23 and the second connecting hole 31, and then axially limited by an elastic retaining ring or a cotter pin to prevent the pin from falling out. This connection method has a simple structure and is quick to install, making it suitable for temporary work scenarios where high installation efficiency is required.

[0059] During construction, at the intersection of the already firmly tied reinforcing bars, first install the first mounting component 1, then cover the first mounting component 1 with the second mounting component 2, and lock and tighten the locking component by passing it through the first locking hole 11 and the second locking hole 21 in sequence. Then, insert the suspension component 3 into the fixing part 22 of the second mounting component 2, and lock the connecting component by passing it through the first connecting hole 23 and the second connecting hole 31. Finally, a safety rope can be stretched between any two installed suspension components to meet the requirements for hanging a safety belt. This device can be removed before concrete pouring, or the first mounting component 1 and the second mounting component 2 can be embedded in the structure.

[0060] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
