Description

Technical Field

[0001] This utility model relates to the field of high-altitude operation safety protection technology, and in particular to a safety buckle for connecting with a fall arrestor. Background Technology

[0002] When working at heights, it is often necessary to use a combination of fall arrestors and safety buckles to ensure the personal safety of the operators. Currently, safety buckles are generally metal or high-strength non-metallic ring connectors with self-locking doors, used to connect the operator's safety rope and fall arrestor together.

[0003] While these safety buckles can protect operators, they are generally push-button type and have relatively low strength. In the event of a sudden fall, the connection between the safety buckle and the fall arrestor may break. Furthermore, the existing safety buckles have a weak ability to prevent the safety rope from shifting. When connected to the operator, the safety rope can slide, potentially causing it to shift and break due to friction. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a safety buckle for connection with a fall arrestor. To achieve the above objectives, this utility model adopts the following technical solution: A safety buckle for connection with a fall arrestor includes a locking mechanism that is fitted onto and fixed to the fall arrestor, and a guiding mechanism connected to the locking mechanism that allows guidance of the safety rope and limits its movement. The locking mechanism includes a fixing part and a receiving part disposed on the fixing part. The receiving part includes a first connecting plate that is disposed on the fixing part and extends horizontally, and a second connecting plate that is connected to the first connecting plate and extends towards each other. The first connecting plate and the second connecting plate together form a cavity for accommodating the fall arrester. Meanwhile, the safety buckle also includes a limiting mechanism disposed on the second connecting plate for selectively opening the cavity.

[0005] Furthermore, the second connecting plate is configured as a hollow structure, and the limiting mechanism includes a limiting plate disposed within the second connecting plate and allowing vertical movement along the second connecting plate, a reinforcing plate disposed on the limiting plate and extending horizontally outward, and a threaded fastener passing through the reinforcing plate and capable of connecting the reinforcing plates together in a fixed manner.

[0006] Furthermore, the limiting mechanism also includes an elastic portion disposed within the second connecting plate, the elastic portion being configured to abut against the limiting plate to continuously actuate the limiting plates toward each other to keep the cavity closed.

[0007] Furthermore, the elastic part is configured as a spring, and the extension length of the spring is less than the vertical length of the second connecting plate, so as to prevent the limiting plate from separating from the second connecting plate under the action of the spring.

[0008] Furthermore, a connecting post is provided on one limiting plate, and a receiving post is provided on the other limiting plate, the receiving post being configured to allow them to fit together in a manner that accommodates the connecting post.

[0009] Furthermore, the fixing part is configured as a hollow structure, and a first channel and a second channel are respectively opened on its adjacent two sides for the safety rope to pass through, and the guiding mechanism extends along the second channel.

[0010] Furthermore, the guiding mechanism includes a support frame that is fixed to the fixing part and extends horizontally. A first guide wheel is arranged on the support frame in a relatively opposite manner. The first guide wheel is rotatably connected to the support frame, and together they form a path for the safety rope to pass through in order to limit the safety rope.

[0011] Furthermore, the support frame includes at least four support rods that are fixedly mounted on the fixed part in pairs and extend horizontally, and a support seat that is disposed at the end of the support rod and fixed to the support rod relative to it. The first guide wheel is rotatably mounted on the support seat.

[0012] Furthermore, the support frame also includes reinforcing plates disposed on the fixing part and surrounding each support rod to strengthen the connection between the support rod and the fixing part.

[0013] Furthermore, the guiding mechanism also includes a second guide wheel that is rotatably disposed within the fixed part, and the safety rope is configured to pass around the second guide wheel and extend to the first guide wheel, so as to convert the sliding friction between the safety rope and the fixed part into rolling friction.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model includes a locking mechanism that is sleeved on and fixed to a fall arrester. The locking mechanism includes a fixing part and a receiving part disposed on the fixing part. The receiving part includes a first connecting plate horizontally extending and disposed on the fixing part, and a second connecting plate connected to the first connecting plate and extending towards it. The first and second connecting plates together form a cavity for accommodating the fall arrester. The safety buckle also includes a limiting mechanism disposed on the second connecting plate for selectively opening the cavity. In this way, the fall arrester can be positioned within the cavity and blocked by the limiting mechanism within the cavity. This improves its connection strength.

[0015] 2. This utility model also includes a guiding mechanism, which is connected to the locking mechanism to guide and limit the safety rope. This prevents the safety rope from slipping due to operator movement during use, which could lead to rope deviation and friction breakage. Attached Figure Description

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] To better understand the purpose, structure, and function of this utility model, the following detailed description, in conjunction with the accompanying drawings, describes a safety buckle for connecting with a fall arrestor.

[0020] Figure 1 The schematic diagram illustrates the overall structure of a safety buckle according to the present invention for connection with a fall arrestor. In such a way... Figure 1 In the embodiment shown, the safety buckle 100 for connection with the fall arrester includes a locking mechanism 1 configured to allow it to be fitted onto the fall arrester (not shown) and connected to the fall arrester in a relatively fixed manner.

[0021] At the same time, such as Figure 1 , 2 As shown, a guide mechanism 2 is also provided on the locking mechanism 1. The guide mechanism 2 is used to form the path of movement of the safety rope 10 and allows for restriction of the radial movement of the safety rope 10. In the illustrated embodiment, the locking mechanism 1 includes a fixing part 11 and a receiving part 12 provided on the fixing part 11.

[0022] Among them, such as Figure 2 As shown, the receiving part 12 includes a first connecting plate 121, which is fixedly disposed on the fixing part 11 and extends in the horizontal direction, and a second connecting plate 122 which is connected to the first connecting plate 121 and extends towards each other. The first connecting plate 121 and the second connecting plate 122 together form a cavity 13 for receiving the fall arrester.

[0023] At the same time, such as Figure 1 As shown, the safety buckle 100 also includes a limiting mechanism 3 disposed on the second connecting plate 122 for selectively opening the cavity 13. In this configuration, during use, the limiting mechanism 3 is first opened, thereby opening the cavity 13. At this time, the fall arrestor (not shown in the figure) is placed inside the cavity 13, and the limiting mechanism 3 is closed, thereby connecting the fall arrestor and the locking mechanism together.

[0024] Then, the safety rope located on the fall arrestor is passed around the guide mechanism 2, and the guide mechanism 2 restricts the radial movement of the safety rope 10, thereby preventing the safety rope 10 from deviating during use. This achieves the purpose of protecting the operator.

[0025] In one embodiment, such as Figure 2 As shown, the second connecting plate 122 is configured as a hollow structure. The limiting mechanism 3 includes a limiting plate 31 disposed within the second connecting plate 122, the limiting plate 31 being configured to allow vertical movement along the second connecting plate 122 to close the cavity 13. Simultaneously, a horizontally extending reinforcing plate 32 is also disposed on the limiting plate 31.

[0026] In addition, such as Figure 2 As shown, the limiting mechanism 3 also includes a threaded fastener 33 passing through the reinforcing plate 32, the threaded fastener 33 being configured to allow the reinforcing plates 32 to be connected together in a fixed manner. In this way, a stable closure of the cavity 13 is achieved.

[0027] According to a preferred embodiment of the present invention, such as Figure 3As shown, the limiting mechanism 3 also includes an elastic part 34, which is disposed in the second connecting plate 122 and abuts against the limiting plate 31. It is used to continuously apply force to the limiting plate 31, thereby causing the limiting plates 31 to move towards each other to keep the cavity 13 continuously closed.

[0028] In this embodiment, as Figure 3 As shown, the elastic part 34 is configured as a spring, and the extension length of the spring is configured to be less than the vertical length of the second connecting plate 122. In this way, the limiting plate 31 is prevented from disengaging from the second connecting plate 122 under the force of the spring.

[0029] In this configuration, during use, a force is first applied to the reinforcing plate 32, causing it to move in directions away from each other. During this process, the force is transmitted along the reinforcing plate 32 to the limiting plate 31, and then through the limiting plate 31 to the elastic part 34, thereby compressing the elastic part 34 to cause elastic deformation, which in turn causes the cavity 13 to be in an open state.

[0030] Simultaneously, the fall arrestor is placed in the cavity 13, and the force applied to the reinforcing plate 32 is removed. During this process, the deformable part 34 will recover its elastic deformation and continuously apply a force to the limiting plate 31 to move in opposite directions. During this process, the limiting plate 31 will drive the reinforcing plate 32 to move in opposite directions until the limiting plates 31 abut against each other.

[0031] At this point, threaded fasteners 33 are inserted into the reinforcing plates 32, and the oppositely positioned reinforcing plates 32 are connected together by the threaded fasteners 33. This achieves stable closure of the cavity 13, thereby allowing the fall arrestor to be stably installed in the cavity 13.

[0032] It should be noted that, as Figure 2 , 3 As shown, the threaded fastener 33 is configured with a bolt and nut engaging with each other, and the reinforcing plate 32 has a through hole for accommodating the bolt. This configuration allows the bolt to be placed in the through hole, and the reinforcing plate 32 to be locked together by the nut. However, the operation of engaging the bolt and nut with the reinforcing plate 32 and fixing it is well known to those skilled in the art. Therefore, it will not be described in detail here.

[0033] According to a preferred embodiment of the present invention, such as Figure 3As shown, a connecting post 311 is also provided on one limiting plate 31. Meanwhile, a receiving post 312 is also provided on the other limiting plate 31. In the illustrated embodiment, the receiving post 312 is configured to allow it to mate with the connecting post 311. Specifically, the receiving post 312 is configured as a hollow structure to accommodate the connecting post 311. In this way, a stable cavity 13 can be further formed.

[0034] In one embodiment, such as Figure 2 As shown, the fixing part 11 is configured as a hollow structure, and a first channel 111 and a second channel 112 are respectively opened on its adjacent two sides for the safety rope 10 to pass through. The guiding mechanism 2 extends along the second channel 112. In the illustrated embodiment, the guiding mechanism 2 and the limiting mechanism 3 are arranged in a relative manner. In this way, the forces acting on the limiting mechanism 3 and the guiding mechanism 2 are in a straight line, thereby improving their force-bearing performance.

[0035] In the illustrated embodiment, such as Figure 1 As shown, the guiding mechanism 2 includes a support frame 21, which is fixed to the fixing part 11 and extends horizontally. Meanwhile, a first guide wheel 22 is arranged opposite to the support frame 21, and the first guide wheel 22 is rotatably connected to the support frame 21, forming a path for the safety rope 10 to pass through.

[0036] It should be noted that, as Figure 1 , 4 As shown, the first guide wheel 22 is configured as a pulley, and the relative distance between its sliding edges is approximately equal to the diameter of the safety rope. This limits the movement of the safety rope 10, thereby preventing it from shifting during movement.

[0037] In one embodiment, such as Figure 1 , 4 As shown, the support frame 21 includes at least four support rods 211 that are fixedly mounted on the fixing part 11 in pairs and extend horizontally, and a support seat 212 that is disposed at the end of the support rods 211 and fixed together with the support rods 211. The first guide wheel 22 is rotatably mounted on the support seat 212.

[0038] According to a preferred embodiment of the present invention, such as Figure 1 As shown, the support frame 21 also includes a reinforcing plate 213, which is disposed on the fixing part 11 and surrounds each support rod 211 to strengthen the connection between the support rod 211 and the fixing part 11.

[0039] In one embodiment, such as Figure 4As shown, the guiding mechanism 2 also includes a second guide wheel 23, which is rotatably disposed within the fixing part 11. Meanwhile, the safety rope 10 is configured to pass over the second guide wheel 23 and extend between the opposing first guide wheels 21. In this way, the sliding friction between the safety rope 10 and the fixing part 11 is converted into rolling friction, thereby improving the service life of the safety rope 10.

[0040] The operation of the safety buckle 100, which is used to connect with the fall arrestor according to this utility model, is as follows.

[0041] First, a force is applied to the reinforcing plate 32, causing it to move in a direction away from each other. During this process, the force is transmitted along the reinforcing plate 32 to the limiting plate 31, and then through the limiting plate 31 to the elastic part 34, thereby compressing the elastic part 34 to undergo elastic deformation, which in turn causes the cavity 13 to be in an open state.

[0042] Simultaneously, the fall arrestor is placed in the cavity 13, and the force applied to the reinforcing plate 32 is removed. During this process, the deformable part 34 will recover its elastic deformation and continuously apply a force to the limiting plate 31 to move in opposite directions. During this process, the limiting plate 31 will drive the reinforcing plate 32 to move in opposite directions, thereby causing the connecting post 311 and the receiving post 312 located on the limiting plate 31 to cooperate with each other, thereby further strengthening the connection between the limiting plates 31.

[0043] Next, threaded fasteners 33 are inserted into the reinforcing plates 32, and the oppositely positioned reinforcing plates 32 are connected together by the threaded fasteners 33. This achieves stable closure of the cavity 13, thereby allowing the fall arrestor to be stably installed in the cavity 13.

[0044] Then, the safety rope 10 located on the fall arrestor is passed through the first channel 111 and, after passing over the second guide pulley 23, runs along the path between the first guide pulley 22 and the second guide pulley 23. This causes the safety rope 10 to be limited by the first guide pulley 22 and the second guide pulley 23.

[0045] Finally, the operator and the end of the safety rope 10 are connected together. This completes the arrangement of the device 100. In this way, during use, the safety rope 10 is limited by the first guide wheel 22 and the second guide wheel 23, and the locking mechanism 1, the limiting mechanism 3 and the fall arrestor are stably connected together, thereby ensuring the personal safety of the operator.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
