Description

Technical Field

[0001] This utility model relates to the field of pin structure technology, and in particular to a pin structure with radial impact resistance function. Background Technology

[0002] Pins are a common type of connector with wide applications. They are standardized fasteners that can provide both static fixation and relative movement with the connected parts. They are primarily used at the hinge points of two parts to form a hinge connection. Pins are typically locked with cotter pins, ensuring reliable operation and easy disassembly.

[0003] Currently, the pin structure is relatively simple, mainly consisting of a pin body, a shaft hole, a pin, and a retaining ring. The pin body is mainly used as the main force-bearing element.

[0004] However, the pin shafts in the above-mentioned pin structures are mostly integrally formed and cylindrical in shape. Since they do not have a reinforcing structure, their overall stress performance is generally poor when facing some radial impact forces, and they may bend. Therefore, we propose a pin structure with radial impact resistance. Utility Model Content

By setting a reinforcing structure, it is convenient to use the cooperation of the filling component and the reinforcing core, so that the entire pin structure has good radial impact resistance performance. By using the cooperation of the docking component and the locking component, it is convenient to assemble the filling component and the reinforcing core.

[0011] A locking assembly is threaded to an end within a circular cavity and is used to secure the filling assembly and the reinforcing core.

[0012] Preferably, the reinforcing core post includes:

[0013] Strengthening column;

[0014] Multiple reinforcing ribs are fixedly connected at equal intervals to the outer surface of the reinforcing column, and the cross-sectional profile of each reinforcing rib is triangular.

[0015] Preferably, the filling component includes a retaining sleeve and a plurality of inner grooves formed inside the retaining sleeve, and the internal contour dimensions of each inner groove are adapted to the external contour dimensions of the corresponding reinforcing rib.

[0016] Preferably, a first rubber sleeve is fixedly connected to the outer surface of the retaining sleeve, and a second rubber sleeve is fixedly connected to the outer surface of the reinforcing core, and the outer contour of the second rubber sleeve changes with the outer contour of the reinforcing core.

[0017] Preferably, the docking assembly includes a docking block fixedly connected to the inner wall of the circular cavity and a docking groove formed on the end face of the reinforcing column, and the docking block and the docking groove are inserted into each other, and the docking block is specifically a conical triangular block.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides, for example Figure 1-4 The diagram shows a pin structure with radial impact resistance.

[0028] Example 1

[0029] The device includes a pin body 1 and a pin hole 2 formed on the pin body 1. The pin body 1 is provided with a reinforcing structure, which includes: a circular cavity 3, which is formed inside the pin body 1; a filling component 4, which is inserted into the circular cavity 3; a reinforcing core 5, which is inserted into the filling component 4, and the filling component 4 and the reinforcing core 5 cooperate to support the pin body 1; a docking component 8, which is disposed between the circular cavity 3 and the reinforcing core 5, and is used for docking the reinforcing core 5 with the pin body 1; and a locking component 9, which is threaded to the end of the circular cavity 3. The locking component 9 is used to fix the filling component 4 and the reinforcing core 5. The filling component 4 is inserted into the reinforcing core 5, and then the reinforcing core 5 is inserted into the cavity 3. The docking component 8 is used to quickly dock the reinforcing core 5 with the cavity 3 and limit the reinforcing core 5. Then the locking component 9 is screwed into the cavity 3 to fix the filling component 4 and the reinforcing core 5. This design uses the cooperation of the filling component 4 and the reinforcing core 5 to make the entire pin structure have good radial impact resistance performance. The overall structure is simple and easy to assemble and replace later.

[0030] Furthermore, the reinforcing core 5 includes: a reinforcing column 501; and multiple reinforcing ribs 502, which are equidistantly fixed to the outer surface of the reinforcing column 501, and the cross-sectional profile of each reinforcing rib 502 is triangular. By utilizing the cooperation between the equidistantly distributed triangular reinforcing ribs 502 and the reinforcing column 501, it has good impact resistance when facing radial impact force, and thus will not be easily bent.

[0031] Furthermore, the filling component 4 includes a retaining sleeve 401 and a plurality of inner grooves 402 formed inside the retaining sleeve 401, and the internal contour dimensions of each inner groove 402 are adapted to the external contour dimensions of the corresponding reinforcing rib 502; this facilitates the insertion of the reinforcing rib 502 into the inner groove 402, thereby facilitating the assembly and mutual positioning of the reinforcing core 5 and the filling component 4. At the same time, the design of the retaining sleeve 401 and the inner groove 402 also has good resistance to radial impact.

[0032] Furthermore, the docking assembly 8 includes a docking block 801 fixedly connected to the inner wall of the circular cavity 3 and a docking groove 802 opened on the end face of the reinforcing column 501. The docking block 801 is inserted into the docking groove 802. Specifically, the docking block 801 is a conical triangular block. By inserting the docking groove 802 on the reinforcing column 501 into the docking block 801, the conical triangular block-shaped docking block 801 can be quickly docked with the docking groove 802 and can limit the reinforcing core column 5, thereby preventing the reinforcing core column 5 from rotating after installation.

[0033] Furthermore, the locking assembly 9 includes a locking block 901 threadedly connected to the inner wall of the cavity 3 and an internal hexagonal groove 902 formed on one side of the locking block 901. The end face of the locking block 901 is in close contact with the end face of the corresponding filling assembly 4 and the end face of the corresponding reinforcing core 5. By inserting an internal hexagonal wrench into the internal hexagonal groove 902, the locking block 901 is rotated, causing the locking block 901 to be screwed into the cavity 3, thereby squeezing the reinforcing core 5 and the filling assembly 4, thus fixing the filling assembly 4 and the reinforcing core 5.

[0034] Example 2

[0035] Example 2 further discloses, based on Example 1, that: a first rubber sleeve 6 is fixedly connected to the outer surface of the retaining sleeve 401, and a second rubber sleeve 7 is fixedly connected to the outer surface of the reinforcing core 5, and the outer contour of the second rubber sleeve 7 changes with the outer contour of the reinforcing core 5; by setting a thin layer of the first rubber sleeve 6 and the second rubber sleeve 7, the retaining sleeve 401 can be more tightly connected to the cavity 3 on the pin body 1, and the retaining sleeve 401 can be more tightly connected to the reinforcing core 5, thereby avoiding loosening and thus preventing the radial impact force from being distributed better.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
