Description

Technical Field

[0001] This utility model relates to the technical field of guide pin devices, specifically to an external four-way guide pin for automobiles. Background Technology

[0002] In the automotive industry, guide pins, as key components for positioning and connecting parts, directly impact the assembly efficiency and long-term operational reliability of related automotive systems due to their ease of assembly, sealing performance, and the durability of their cushioning components. However, existing guide pins suffer from the following significant problems in practical applications:

[0003] like Figure 5 As shown, traditional guide pins often adopt the assembly method of "guide pin screw 6 engaging and fixing to sleeve end 3". During assembly, the guide pin body and external equipment must be precisely aligned first. During the alignment process, the alignment is prone to failure due to the displacement of the component position. Subsequently, additional operation of the guide pin screw is required to complete the fixing. This not only increases the assembly steps and prolongs the assembly time, but also increases the complexity of manual operation, making it difficult to meet the needs of efficient assembly in automobile production.

[0004] Although some guide pins are equipped with a buffer structure, the connection method between the buffer component and the guide pin body is unreasonable. Traditional connection methods often do not consider the impact of rotational stress on the buffer component. During the use of the guide pin, the buffer component is prone to surface stress due to rotation, which can lead to problems such as breakage and wrinkles. This significantly reduces the buffering effect and service life of the buffer component, and increases the maintenance cost and replacement frequency of automotive parts. Utility Model Content

[0005] Technical problems to be solved

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an external four-way guide pin for automobiles, which can effectively solve the problems in the existing technology.

[0007] Technical solution

[0008] This utility model provides an external four-sided guide pin for automobiles, including a guide pin rod and an integrally fixed sleeve end. The guide pin rod includes a middle section of a square column and two end sections of a cylindrical structure. A buffer rubber sleeve is sleeved on the outer side of the middle square column section. A placement groove is opened at the top of the sleeve end, and a threaded rod is fixed in the placement groove. A nut is sleeved on the outer side of the threaded rod. A mating groove is opened on the outer wall of the square column. Multiple sets of protrusions that are fixedly engaged with the mating groove are fixed on the inner side of the buffer rubber sleeve.

[0009] Furthermore, the sleeve end is a square structure with rounded corners, and the size of the mating groove is adapted to the size of the washer.

[0010] Furthermore, the docking grooves are provided in two sets, one above the other, on each side of the square column.

[0011] Furthermore, the docking groove has a circular annular structure.

[0012] Furthermore, the outer side of the buffer rubber tube is provided with multiple sets of groove structures at equal intervals, and the interior of the buffer rubber tube is provided with a square groove structure.

[0013] Beneficial effects

[0014] In this invention, a placement groove structure is provided at the top of the sleeve end, and a threaded rod structure is fixed therein. Therefore, the nut structure can be directly engaged and fixed with the threaded rod through a washer. The washer is set in the placement groove. Compared with the existing method of engaging and fixing the sleeve end with a guide pin screw, in use, the exposed threaded rod structure can be pre-connected with the external equipment, the interface is sealed by the washer, and then fixed to the outside of the external equipment by the nut to achieve the function of fastening. This avoids the current situation of first aligning and then using a guide pin screw to fix the connection.

[0015] In this device, the multiple sets of docking grooves on the outer side of the square column can be fixedly engaged with the protruding structure in the buffer rubber cylinder structure to achieve the connection and fixation between the two. The outer side of the square column can be sleeved with the buffer rubber cylinder. The square docking method can reduce the surface stress caused by rotation on the buffer rubber cylinder, thereby reducing the occurrence of damage and wrinkles caused by this stress.

[0023] 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example: An external four-way guide pin for automobiles, see attached document. Figure 1 - Appendix Figure 4 The guide pin part 1 includes a guide pin rod part 1 and an integrally fixed sleeve end 3. The guide pin rod part 1 includes a middle section of a square column 11 and two end sections of a cylindrical structure. A buffer rubber tube 2 is sleeved on the outer side of the middle square column 11 section. A placement groove 31 is opened at the top of the sleeve end 3. A threaded rod 4 is fixed in the placement groove 31. A nut 5 is sleeved on the outer side of the threaded rod 4. A mating groove 12 is opened on the outer wall of the square column 11. Multiple sets of protrusions 21 structures that are fixedly engaged with the mating groove 12 are fixed on the inner side of the buffer rubber tube 2.

[0026] The sleeve end 3 is a square structure with rounded corners, and the size of the mating groove 12 is adapted to the size of the washer 51. Multiple sets of groove structures are equidistantly opened on the outer side of the buffer rubber tube 2, and a square groove structure is opened through the inside of the buffer rubber tube 2. A placement groove 31 structure is opened at the top of the sleeve end 3, and the threaded rod 4 structure is fixed in it. Therefore, the nut 5 structure can be directly engaged and fixed with the threaded rod 4 through the washer 51. The washer 51 is set in the placement groove 31. Compared with the existing method of engaging and fixing the sleeve end 3 with the guide pin screw 6, when this device is used, the exposed threaded rod 4 structure can be pre-connected with the external equipment, the interface is sealed by the washer 51, and then fixed to the outside of the external equipment by the nut 5 to achieve the function of fastening. This avoids the current situation of first aligning and then using the guide pin screw 6 to fix the connection.

[0027] Two sets of docking grooves 12 are provided on each side of the square column 11, one above the other. The docking grooves 12 are circular ring structures. In this device, the multiple sets of docking grooves 12 on the outer side of the square column 11 can be fixedly engaged with the protrusions 21 in the buffer tube 2 structure to achieve the connection and fixation between the two. The outer side of the square column 11 can be sleeved with the buffer tube 2. The square docking method can reduce the surface stress caused by rotation on the buffer tube 2, thereby reducing the occurrence of damage and wrinkles caused by this stress.

[0028] 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 the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
