Description

Technical Field

[0001] This utility model relates to the technical field of hook connection components, and in particular to a hook connection component for use on a differential gear. Background Technology

[0002] A fall arrestor, also known as a speed differential, is a protective device. It can quickly brake and lock a falling object within a limited distance, making it suitable for cargo hoisting, protecting the lives of ground personnel and preventing damage to the hoisted object. Currently, speed differentials are connected to hooks via a connecting assembly. Existing connecting assemblies consist of a hanging ring and a connector. The rope in the speed differential connects to the hanging ring, and the connector connects to the hook. However, this type of connecting assembly can only be used with one type of hook, leading to high inventory pressure for manufacturers, high production and operating costs, and an unreasonable structural design. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hook connection component for a differential gear, which not only reduces the manufacturer's production and operation costs, but also reduces inventory pressure, has very good practicality, and has a reasonable overall structural design.

[0004] The technical solution adopted by this utility model to solve its technical problem is a hook connection assembly for a differential gear. The connection assembly includes a hook ring body, a first connector, a first indicator, and a second connector. The bottom of the hook ring body is provided with a hook ring seat, and the hook ring seat is provided with a cavity. A first axial hole is provided through the cavity. The first connector is provided with a first connecting part, which is tightly inserted into the first axial hole. The lower end of the first connecting part extends out of the first axial hole. The first indicator is installed on the first connecting part and is positioned opposite to the first axial hole. When the first connector is subjected to a destructive force, the first indicator moves down to outside the first axial hole. The second connector is provided with a second connecting part and a third connecting part at the top and bottom. The second connecting part is detachably connected to the lower end of the first connecting part, and both the first connecting part and the third connecting part can be connected to the corresponding hook.

[0005] The advantages of the above technical solution are as follows: By setting a first connecting part on the first connector and a second connecting part on the second connector, and making the first connecting part and the second connecting part detachably connected, and both the first connecting part on the first connector and the third connecting part on the second connector can be connected to hooks, the connection of the connecting component with different types of hooks can be achieved simply by installing or removing the second connecting part. This effectively reduces the production quantity requirement of the hanging ring body, thereby reducing the manufacturer's production and operating costs and reducing inventory pressure. Furthermore, when the first connecting part is subjected to a destructive force, it will move downwards, causing the first indicator to move outside the first axial hole. The user can clearly identify the status change of the connecting component, thereby achieving the purpose of providing a prominent reminder of the usage status. The overall structural design is reasonable and has excellent practicality.

[0006] Furthermore, the second connecting part is a second axial hole, the lower end of the first connecting part is inserted into the second connecting part, and the first connecting part and the second connecting part are detachably connected and engaged through a first connecting shaft.

[0007] The advantages of adopting the above technical solution are: by setting the second connecting part as the second axial hole, the structural design of each component of the connecting assembly is reasonable while ensuring connection stability. Furthermore, by adopting the first connecting shaft, the connection stability of the first connecting part and the second connecting part is higher, and the performance is better.

[0008] Furthermore, the first connecting part is provided with a through first radial hole, and the second connecting part is provided with a through second radial hole. The first radial hole and the second radial hole cooperate with the first connecting shaft, and a threaded connection structure is provided between the first connecting shaft and the first radial hole or the second radial hole.

[0009] The advantages of the above technical solution are as follows: by adopting the design of the first radial hole and the second radial hole, the installation of the first connecting shaft is realized. In addition, the design of the threaded connection structure enables the first connecting piece and the second connecting piece to achieve a double fixed connection, which ensures the reliability of use.

[0010] Furthermore, there are two second radial holes, which are symmetrically arranged on the second connecting part, and the threaded connection structure is located between the lower end of the first connecting shaft and the corresponding second radial hole.

[0011] The advantages of the above technical solution are: by using the design of two second radial holes and the design of setting the threaded connection structure at the lower end of the first connecting shaft, the installation of the first connecting shaft is more stable, and the connection and fixation of the first connecting piece and the second connecting piece are more reasonable.

[0012] Furthermore, the lower end of the first connecting shaft is provided with a shaft protrusion, which extends out of the second connecting member. The shaft protrusion is provided with a retaining element, and the retaining element is detachable.

[0013] The advantages of the above technical solution are as follows: by setting a shaft protrusion at the lower end of the first connecting shaft and by setting a detachable clip on the shaft protrusion, the first connecting shaft will not come out while ensuring that the first connecting piece and the second connecting piece are detachable. The installation of the first connecting shaft is more stable and the structural design is reasonable.

[0014] Furthermore, the third connecting part is a groove, and the left and right sides of the third connecting part are through-connected. The third connecting part is also provided with two third radial holes, which are used to install the second connecting shaft.

[0015] The advantages of the above technical solution are as follows: During installation, the corresponding hook is inserted into the third connecting part, the mounting radial hole on the hook and the third radial hole are aligned, and the hook is positioned by the second connecting shaft. The third connecting part is set as a groove, which provides reliable reinforcement for the installation of the hook. The connection stability between the second connecting part and the hook is higher, and the stress on the connecting component is also relatively reasonable.

[0016] Furthermore, the first connector is also provided with a limiting stop, which is connected to the lower end face of the limiting stop. The limiting stop is used to form a limiting fit with the cavity.

[0017] The advantages of adopting the above technical solution are: by setting a limiting stop, the first connecting piece will not fall out after being subjected to a destructive force and moving downwards, thus ensuring the safety of use.

[0018] Furthermore, the connecting assembly also includes a second indicator, which is disposed between the limiting stop and the first indicator, and the second indicator is at least partially located outside the cavity.

[0019] The advantages of adopting the above technical solution are: by setting a second indicator, the second indicator can display the normal use status of the connecting device, the usage status reminder of the connecting components is better, and the use is more reasonable.

[0020] Furthermore, the second indicator is made of a flexible non-metallic material, and both ends of the second indicator are connected to the limiting stop and the cavity, respectively.

[0021] The advantages of the above technical solution are: when the first connecting part moves, the second indicator will be compressed by the limiting stop and the cavity. Therefore, the second indicator is made of flexible non-metallic material, which can avoid the phenomenon of the second indicator being compressed, broken and flying out, making it safer to use.

[0025] Please see Figures 1 to 6As shown, a hook connection assembly for a differential gear includes a hook body 1, a first connector 2, a first indicator 3, and a second connector 4. The hook body 1 has a hook seat 5 at its bottom, and a cavity on the hook seat 5. A first axial hole 6 is provided through the cavity, located at the center of the bottom of the cavity. The first connector 2 has a first connecting portion 7, which is tightly inserted into the first axial hole 6. It should be noted that a certain amount of tightening force is formed between the first connecting portion 7 and the first axial hole 6. The lower end of the first connecting portion 7 extends out of the first axial hole 6. An indicator 3 is installed on the first connecting part 7 and positioned opposite the first axial hole 6. A mounting ring groove is formed on the first connecting part 7 opposite the first axial hole 6. The first indicator 3 cooperates with the mounting ring groove. When the first connecting part 2 is driven by a destructive force, the first indicator 3 moves down to the outside of the first axial hole 6. Under normal conditions, the first indicator 3 is covered by the hanging ring seat 5. The second connecting part 4 is provided with a second connecting part 8 and a third connecting part 9 at the top and bottom. The second connecting part 8 is detachably connected to the lower end of the first connecting part 7, and both the first connecting part 7 and the third connecting part 9 can be connected to the corresponding hook 20.

[0026] In the above structure, a first connecting part 7 is provided on the first connecting member 2, and a second connecting part 8 is provided on the second connecting member 4, and the first connecting part 7 and the second connecting part 8 are detachably connected. Furthermore, both the first connecting part 7 on the first connecting member 2 and the third connecting part 9 on the second connecting member 4 can connect to the hook 20. That is, when the first connecting member 2 and the hanging ring body 1 are used together, the first connecting member 2 serves to connect the hook 20 and the hanging ring body 1. When the second connecting member 4 is used together with the first connecting member 2 and the hanging ring body 1, the first connecting member 2 connects the second connecting member 4 and the hanging ring body. The function of the first connector 2 is that the second connector 4 also serves as a hook 20. Therefore, by simply installing or removing the second connector 4, the connection between the connecting component and different types of hooks 20 can be achieved, which effectively reduces the production quantity requirement of the hanging ring body 1 and achieves the purpose of reducing the manufacturer's production and operating costs and reducing inventory pressure. Furthermore, when the first connector 2 is subjected to a destructive force, it will move downward, causing the first indicator 3 to move outside the first axial hole 6. The user can clearly identify the status change of the connecting component, thereby achieving the purpose of providing a prominent reminder of the usage status. The overall structural design is reasonable and has very good practicality.

[0027] In this embodiment, the second connecting part 8 is a second axial hole, the lower end of the first connecting part 7 is inserted into the second connecting part 8, and the first connecting part 7 and the second connecting part 8 are detachably connected and engaged through the first connecting shaft 10. In the above structure, the second connecting part 8 is set as a second axial hole. Under the premise of ensuring connection stability, the structural design of each component of the connecting assembly is reasonable. Furthermore, by adopting the first connecting shaft 10, the connection stability of the first connecting part 2 and the second connecting part 4 is higher, and the use effect is better.

[0028] In this embodiment, the first connecting part 7 is provided with a through first radial hole 11, and the second connecting part 8 is provided with a through second radial hole 12. The first radial hole 11 and the second radial hole 12 cooperate with the first connecting shaft 10, and a threaded connection structure 13 is provided between the first connecting shaft 10 and the first radial hole 11 or the second radial hole 12. In the above structure, by adopting the design of the first radial hole 11 and the second radial hole 12, the installation of the first connecting shaft 10 is realized. Furthermore, by adopting the design of the threaded connection structure 13, the first connecting member 2 and the second connecting member 4 achieve a double fixed connection, ensuring the reliability of use.

[0029] In this embodiment, two second radial holes 12 are provided and symmetrically arranged on the second connecting part 8. That is to say, the second radial holes 12 are also arranged to penetrate the second connecting member 4, and the threaded connection structure 13 is provided between the lower end of the first connecting shaft 10 and the corresponding second radial hole 12. In this way, the connection between the first connecting shaft 10 and the second connecting member 4 is more complete. In the above structure, by adopting the design of two second radial holes 12 and the design of setting the threaded connection structure 13 at the lower end of the first connecting shaft 10, the installation of the first connecting shaft 10 is more stable, and the connection and fixation of the first connecting member 2 and the second connecting member 4 is more reasonable.

[0030] In this embodiment, the lower end of the first connecting shaft 10 is provided with a shaft protrusion 14, which extends out to the outside of the second connector 4. A retaining member 15 is provided on the shaft protrusion 14, and the retaining member 15 is detachable. It should be noted that a retaining ring groove is provided on the shaft protrusion 14, and the retaining member 15 cooperates with the retaining ring groove. In the above structure, by providing a shaft protrusion 14 at the lower end of the first connecting shaft 10 and by providing a detachable retaining member 15 on the shaft protrusion 14, the first connecting shaft 10 will not come out while ensuring that the first connector 2 and the second connector 4 are detachable. The installation of the first connecting shaft 10 is more stable, and the structural design is reasonable.

[0031] In this embodiment, the third connecting part 9 is a groove, and the left and right sides of the third connecting part 9 are through-connected. Two third radial holes 16 are also provided through the third connecting part 9. That is to say, the third radial holes 11 are also provided through the second connecting member 4. The third radial holes 11 are used to install the second connecting shaft 17. The second connecting shaft 17 can be a riveted pin. In the above structure, during installation, the corresponding hook 20 is inserted into the third connecting part 9, the mounting radial holes on the hook 20 and the third radial holes 16 are aligned, and the second connecting shaft 17 is used to limit the position of the hook 20. The third connecting part 9 is set as a groove, thereby providing reliable reinforcement for the installation of the hook 20. The connection stability between the second connecting member 4 and the hook is higher, and the stress on the connecting component is also relatively reasonable.

[0032] In this embodiment, the first connector 2 is further provided with a limiting stop 18. The first connector 7 is connected to the lower end face of the limiting stop 18. The limiting stop 18 is used to form a limiting fit with the cavity. In the above structure, by setting the limiting stop 18, the first connector 2 will not fall out after being subjected to a destructive force and moving downward, thus ensuring the safety of use.

[0033] In this embodiment, the connecting component further includes a second indicator 19, which is disposed between the limiting stop portion 18 and the first indicator 3. The second indicator 19 is at least partially located outside the cavity. In the above structure, by providing the second indicator 19, the second indicator 19 can display the normal use status of the connecting device, and the usage status reminder effect of the connecting component is better and the use is more reasonable.

[0034] In this embodiment, the first indicator 3 is a red indicator and the second indicator 19 is a blue indicator, so that the user can intuitively understand the usage status of the connection component through the first indicator 3 and the second indicator 19.

[0035] In this embodiment, both the first indicator 3 and the second indicator 19 are made of flexible non-metallic material, and the two ends of the second indicator 19 are connected to the limiting stop 18 and the cavity, respectively. That is, the upper end of the first indicator 3 interacts with the lower surface of the limiting stop 18, and the lower end of the first indicator 3 interacts with the bottom surface of the cavity. In the above structure, when the first connecting member 2 moves, the second indicator 19 will be compressed under the action of the limiting stop 18 and the cavity. Therefore, the second indicator 19 is made of flexible non-metallic material, which can prevent the second indicator 19 from being compressed, broken, and flying out, making it safer to use.

[0036] In this embodiment, when the first connector 2 and the hanging ring body 1 are used together, the first radial hole 11 on the first connecting part 7 is also used to install the second connecting shaft 17. It should be noted that the hook 20 of this type has an integrally formed connecting seat, so there is no need to install the second connector 4. An axial hole is provided on the connecting seat, and a radial hole is provided through the axial hole. During installation, the first connecting part 7 is inserted into the axial hole on the hook 20, the radial hole on the hook 20 and the first radial hole 11 are aligned, and the second connecting shaft 17 is used to define the position of the hook 20.
