Description

Technical Field

[0001] This utility model relates to the field of construction safety protection technology, and in particular to a safety net connection buckle for construction. Background Technology

[0002] Construction safety nets are indispensable safety protection facilities at construction sites. They are usually composed of netting, edge ropes, and tie ropes. They are mainly used to prevent people or objects from falling, avoid injury to personnel and equipment below caused by falling objects, protect the lives of construction workers, and also reduce the spread of construction dust, thus playing a certain role in environmental protection.

[0003] In actual construction, safety nets for buildings need to be laid over a large area. Since the size of a single safety net is limited, multiple safety nets need to be connected to each other. Connecting clips are components specifically used to fix and connect safety nets. Their function is to firmly connect adjacent safety nets together, ensuring the stability and reliability of the overall structure of the safety net, so that it will not easily separate or fall off during the protection process.

[0004] The existing safety net connection clip for construction has the following shortcomings:

[0005] Existing safety net connection clips for construction mostly adopt simple hook or clamp structures. These clips rely on a single application of force for fixation and lack a stable locking mechanism. During long-term use, the hook structure is prone to loosening due to external forces such as wind and personnel collisions, and the clamp structure may also experience a decrease in clamping force due to deformation. This can cause gaps or even separation at the connection points of the safety net, posing a significant safety hazard. Furthermore, existing clips are usually designed in a single specification, making it difficult to adapt to safety net ropes of different thicknesses and materials. Moreover, installation requires repeated adjustments to position and force, and disassembly requires the assistance of tools, making the operation cumbersome and seriously affecting construction efficiency. Utility Model Content

[0006] This utility model proposes a safety net connection buckle for construction, which features stable locking, convenient installation, and high adaptability, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a safety net connecting buckle for construction, comprising two connecting plates, wherein a U-shaped reinforcing plate is slidably sleeved on both the front and rear sides of the outer surface of the two connecting plates.

[0008] Both of the two connecting plates have semi-cylindrical grooves extending through the front and rear sides. The left side of the lower surface of the top connecting plate and the right side of the upper surface of the bottom connecting plate are provided with insertion grooves. A rotating groove is provided on the side of the inner wall of the insertion groove away from the outer surface of the connecting plate. Clamping components are provided on the right side of the lower surface of the top connecting plate and the left side of the upper surface of the bottom connecting plate.

[0009] The clamping assembly includes a knob, a transmission screw is fixedly connected to the side of the knob near the connecting plate, a sliding groove is provided inside the connecting plate, the end of the transmission screw away from the knob passes through the interior of the sliding groove and is fixedly connected to a drive wheel, a driven wheel is engaged with the outer surface of the drive wheel, a rotating column is fixedly connected to one side of the driven wheel, the end of the rotating column away from the driven wheel passes through the insertion groove in another adjacent connecting plate and is fixedly connected to a rotating plate, the rotating plate being rotatably engaged in the interior of the rotating slot in another adjacent connecting plate.

[0010] Preferably, the driven wheel is rotatably connected to the inner surface of the sliding groove on the side away from the transmission screw.

[0011] Preferably, a cylindrical protrusion is provided in the middle of the opposite side of each of the two connecting plates, and a groove is formed in the middle of the cylindrical protrusion, and the knob is rotatably connected inside the groove.

[0012] Preferably, the upper and lower ends of the U-shaped reinforcing plate are provided with arc-shaped grooves, and the inner surface of the arc-shaped grooves is in contact with the outer surface of the cylindrical protrusion.

[0013] Preferably, the outer surface of the transmission screw is threadedly connected to a threaded slide plate, and the outer surface of the threaded slide plate is slidably connected to the inner surface of the sliding groove.

[0014] Preferably, the threaded slide plate has four fixed corners on the side near the U-shaped reinforcing plate, and the U-shaped reinforcing plate has two through-hole fixing slots on both the upper and lower sides, with the end of the fixing block away from the threaded slide plate extending through to the inner surface of the fixing slot.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0016] 1. In this utility model, a gear-driven locking structure is formed through the mutual cooperation between the knob, transmission screw, driving wheel, driven wheel, rotating column, and rotating locking plate. When the knob is turned, the transmission screw drives the driving wheel to rotate, and the driven wheel rotates accordingly, thereby driving the rotating column to make the rotating locking plate engage with the rotating locking slot. This structure utilizes the stable characteristics of gear transmission to make the rotating locking plate form a stable lock under multi-directional force. Compared with traditional hooks or clips, it can effectively resist external pulling, vibration and other forces, greatly improving the firmness and reliability of the safety net connection.

[0017] 2. In this utility model, the rapid reinforcement function is achieved through the cooperation of the U-shaped reinforcing plate, the threaded sliding plate, the fixing block, and the fixing slot. After the two connecting plates are connected, the U-shaped reinforcing plate is placed on the outside, and the knob is turned to rotate the transmission screw. Under the action of the screw, the threaded sliding plate drives the fixing block to insert into the fixing slot, thus completing the rapid fixing of the U-shaped reinforcing plate. This double fixing design not only enhances the overall structural strength of the buckle, but also makes the knob operation simple and convenient, requiring no additional tools, which greatly shortens the installation and disassembly time. Furthermore, the semi-cylindrical slot can be adapted to different thicknesses of net rope, significantly improving construction efficiency and the versatility of the buckle.

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution: it includes two connecting plates 1, with a U-shaped reinforcing plate 2 slidably fitted on both the front and rear sides of the outer surfaces of the two connecting plates 1. Semi-cylindrical grooves 11 extending through the front and rear sides of the opposite faces of the two connecting plates 1 are provided. Insertion grooves 12 are provided on the left side of the lower surface of the top connecting plate 1 and the right side of the upper surface of the bottom connecting plate 1. A rotating groove 13 is provided on the inner wall of the insertion groove 12 away from the outer surface of the connecting plate 1. A clamping assembly 14 is provided on the right side of the lower surface of the top connecting plate 1 and the left side of the upper surface of the bottom connecting plate 1. The clamping assembly 14 includes a knob 141, with a transmission screw 142 fixedly connected to the side of the knob 141 near the connecting plate 1. A sliding groove is provided inside the connecting plate 1 for transmission... The end of the screw 142 away from the knob 141 passes through the interior of the sliding groove and is fixedly connected to the drive wheel 143. The outer surface of the drive wheel 143 is meshed with the driven wheel 144. A rotating column 145 is fixedly connected to one side of the driven wheel 144. The end of the rotating column 145 away from the driven wheel 144 passes through the insertion slot 12 in the adjacent connecting plate 1 and is fixedly connected to the rotating plate 146. The rotating plate 146 is rotatably engaged in the interior of the rotating slot 13 in the adjacent connecting plate 1. The driven wheel 144 is rotatably connected to the inner surface of the sliding groove away from the drive screw 142. A cylindrical protrusion 15 is provided in the middle of the opposite side of the two connecting plates 1. A groove is provided in the middle of the cylindrical protrusion 15. The knob 141 is rotatably connected in the interior of the groove.

[0026] The effect achieved by the entire embodiment 1 is as follows: When connecting two safety nets, the net ropes of the two safety nets are first placed in the semi-cylindrical grooves 11 on opposite sides of the two connecting plates 1. The semi-cylindrical grooves 11 are used to initially position and limit the net ropes. Then, the two connecting plates 1 are joined together. At this time, the rotating plate 146 passes through the insertion groove 12 and enters the rotating groove 13. Then, the knob 141 is rotated. The knob 141 drives the transmission screw 142 to rotate. The transmission screw 142 drives the driving wheel 143 to rotate. The driving wheel 143 drives the driven wheel 144 to rotate through the meshing relationship. The driven wheel 144 then drives the rotating column 145 to rotate, so that the rotating plate 146 rotates and locks in the rotating groove 13, realizing a firm lock between the two connecting plates 1. This ensures that the net rope is tightly clamped in the semi-cylindrical groove 11, preventing the net rope from loosening and ensuring the stability of the safety net connection.

[0027] Example 2: As Figure 3 and Figure 4 As shown, this utility model provides a technical solution: the upper and lower ends of the U-shaped reinforcing plate 2 are provided with arc-shaped grooves 21, the inner surface of the arc-shaped grooves 21 is in contact with the outer surface of the cylindrical protrusions 15, the outer surface of the transmission screw 142 is threadedly connected to a threaded sliding plate 147, the outer surface of the threaded sliding plate 147 is slidably connected to the inner surface of the sliding groove, and the four corners of the threaded sliding plate 147 near the U-shaped reinforcing plate 2 are fixedly connected with fixing blocks 148. The upper and lower sides of the U-shaped reinforcing plate 2 are provided with two vertically penetrating fixing slots 22, and the end of the fixing block 148 away from the threaded sliding plate 147 penetrates to the inner surface of the fixing slot 22.

[0028] The effect achieved by the entire embodiment 2 is as follows: After the initial docking and locking of the two connecting plates 1 is completed, the U-shaped reinforcing plate 2 is slidably sleeved along the outer surface of the connecting plate 1, so that the arc grooves 21 at the upper and lower ends of the U-shaped reinforcing plate 2 fit with the cylindrical protrusions 15 on the connecting plate 1, realizing the quick positioning and installation of the U-shaped reinforcing plate 2. At this time, when the knob 141 is turned, the transmission screw 142 rotates. Since the threaded sliding plate 147 is threadedly connected to the transmission screw 142 and the threaded sliding plate 147 slides with the sliding groove, the threaded sliding plate 147 will move along the sliding groove under the drive of the transmission screw 142. When the threaded sliding plate 147 moves, it drives the fixing block 148 to insert into the fixing slot 22 on the U-shaped reinforcing plate 2, firmly fixing the U-shaped reinforcing plate 2 to the outside of the connecting plate 1, further enhancing the stability of the connection between the two connecting plates 1, preventing the connecting plates 1 from loosening and separating during use, and also improving the fixing strength of the entire buckle to the safety net.

[0029] The working principle of the entire device is as follows: When it is necessary to connect two safety nets, the net ropes of the two safety nets are first embedded into the semi-cylindrical grooves 11 on opposite sides of the two connecting plates 1. The arc-shaped structure of the semi-cylindrical grooves 11 can fit tightly with the net ropes, which plays a good role in positioning and initial fixing of the net ropes. Then, the two connecting plates 1 are joined together, so that the rotating plate 146 of the top connecting plate 1 is aligned with the rotating groove 13 of the bottom connecting plate 1, and the rotating plate 146 of the bottom connecting plate 1 is aligned with the rotating groove 13 of the top connecting plate 1, thus achieving initial splicing.

[0030] Next, the construction worker rotates the knob 141, which drives the transmission screw 142, which is fixedly connected to it, to rotate. Since the transmission screw 142 is fixedly connected to the drive wheel 143, the drive wheel 143 rotates synchronously with the transmission screw 142. The drive wheel 143 drives the driven wheel 144 to rotate through the meshing relationship. When the driven wheel 144 rotates, it drives the rotating column 145 to rotate. The rotating column 145 then drives the rotating plate 146 to rotate in the rotating slot 13 until the rotating plate 146 is fully engaged in the appropriate position of the rotating slot 13, forming a multi-directional force-bearing locking state, which firmly fixes the two connecting plates 1 together, thereby achieving a firm clamping of the safety net rope.

[0031] While locking the connecting plate 1, the U-shaped reinforcing plate 2 is slidably fitted along the front and rear sides of the outer surface of the connecting plate 1. The arc groove 21 of the U-shaped reinforcing plate 2 fits against the cylindrical protrusion 15 of the connecting plate 1, achieving rapid positioning. Simultaneously with rotating the knob 141, the transmission screw 142 continues to rotate. Since the threaded sliding plate 147 is threadedly connected to the transmission screw 142, under the action of the threaded transmission, the threaded sliding plate 147 moves along the sliding groove towards the U-shaped reinforcing plate 2. During the movement of the threaded sliding plate 147, the fixing blocks 148 at its four corners gradually insert into the fixing slots 22 on the U-shaped reinforcing plate 2, thus securing the U-shaped reinforcing plate 2. The U-shaped reinforcing plate 2 is firmly fixed to the outside of the connecting plate 1. The U-shaped reinforcing plate 2 and the connecting plate 1 form a double fixing structure, which greatly enhances the overall structural strength and stability of the buckle, effectively resists external forces such as wind and personnel collisions, and ensures the firmness and reliability of the safety net connection. At the same time, the knob operation is simple and convenient, without the need for additional tools, which improves construction efficiency. When disassembling, the knob 141 is rotated in the opposite direction to make the fixing block 148 disengage from the fixing slot 22, and the U-shaped reinforcing plate 2 can be easily removed. At the same time, the rotating plate 146 will also disengage from the rotating slot 13, thus separating the two connecting plates 1 and realizing the disassembly of the safety net.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
