Description

Technical Field

[0001] The utility model relates to the technical field of adjusting bolt devices, and particularly relates to an adjusting bolt for an automobile braking system. Background Art

[0002] A bolt is a mechanical component, a cylindrical threaded fastener used in conjunction with a nut. It is a type of fastener consisting of a head and a screw rod, which needs to cooperate with a nut to be used for fastening and connecting two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so bolt connection belongs to detachable connection. However, the diameters of existing bolts are all fixed and cannot meet the hole diameters of fixed objects of different sizes. At present, there is no adjusting bolt for an automobile braking system with a reasonable structural design. Content of the Utility Model

[0003] In view of the above-mentioned drawbacks of the prior art, the utility model provides an adjusting bolt for an automobile braking system, which can effectively solve the problem that the hole diameters of fixed objects of different sizes cannot be met in the prior art.

[0004] To achieve the above object, the utility model is realized through the following technical solutions:

[0005] The utility model provides an adjusting bolt for an automobile braking system, including a rod portion. A plurality of groups of rotating plates are fixed on the outer side of the rod portion. The rotating plates have a structure with one end higher and one side lower. A contact panel is arranged on the outer side of the rotating plates. The rotating plates have the style feature of one side lower and one side higher. A plurality of groups of rib strips are fixed on the outer side wall of the rotating plates, and the outer side surfaces of the rib strips are in contact with the inner side wall of the contact panel.

[0006] Further, the rib strip structure has the same shape as the rotating plate. Its lower side is point C and its higher side is point D. In the contact panel, the lower side is point B and the higher side is point A. The arc from point B to point A is flatter than the arc from point C to point D.

[0007] Further, a threaded structure is arranged on the outer side of the contact panel.

[0008] Further, the outer diameter of the contact panel and the rod portion are concentric structures.

[0009] Further, a baffle is arranged at D of the rotating plate, and the height of the baffle is less than the height of point A of the contact panel.

[0010] Further, a plurality of groups of rib strips are arranged on the rotating plate at equal intervals, and the height of each group of rib strips at D is less than the height of the rotating plate at D.

[0011] The technical solution provided by the present utility model has the following beneficial effects compared with the known public technologies:

[0012] By providing a contact panel structure with a threaded structure, during use, the contact panel can be placed outside the rotating plate and engaged and fixed with a preset threaded hole. By rotating the rod portion structure, the rotating plate and the rib are driven to rotate. During the rotation, since the C-D portion of the rib is higher than the B-A portion, the outer side of the rib can gradually press the contact panel structure outward, driving the contact panel to rotate, and then engaging with the threaded structure in the threaded hole until the D point moves to the A point, reaching the maximum pressure value of the crimping. Therefore, during on-site use, according to threaded holes with different inner diameters, the contact panel structure can be engaged and fixed with the threaded hole, and through the methods of rotational engagement and pressurization, the adjustment function can be achieved to meet the on-site installation requirements.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model will be further described below with reference to the embodiments.

[0022] Embodiment: An adjusting bolt for an automotive braking system, referring to the attached Figure 1 - attached Figure 5 , including a rod portion 1. A plurality of rotating plates 3 are fixedly arranged on the outer side of the rod portion 1. The rotating plates 3 have a structure with one end higher and one side lower. A contact panel 2 is arranged on the outer side of the rotating plates 3. The rotating plates 3 have the style feature of one side lower and one side higher. A plurality of rib strips 4 are fixedly arranged on the outer side wall of the rotating plates 3. The outer side surface of the rib strips 4 contacts the inner side wall of the contact panel 2.

[0023] The structure of the rib strips 4 is the same as the shape of the rotating plates 3. Its lower side is point C and its higher side is point D. In the contact panel 2, its lower side is point B and its higher side is point A. The arc from point B to point A is flatter than the arc from point C to point D. During the rotation process, since the C-D part of the rib strips 4 is higher than the B-A part, the outer side surface of the rib strips 4 can gradually press the contact panel 2 structure outwards, driving the contact panel 2 to rotate, and then meshing with the thread structure in the threaded hole until point D moves to point A, reaching the maximum pressure value of the crimping. Therefore, during on-site use, according to threaded holes with different inner diameters, the contact panel 2 structure can be meshed and fixed with the threaded hole, and through the methods of rotational meshing and pressurization, the adjustment function can be achieved to meet the on-site installation requirements.

[0024] A threaded structure is arranged on the outer side of the contact panel 2; the outer diameter of the contact panel 2 and the rod portion 1 are concentric structures; a baffle 31 is arranged at D of the rotating plate 3, and the height of the baffle 31 is less than the height of the A part of the contact panel 2; a plurality of groups of rib strips 4 are arranged equidistantly on the rotating plate 3, and the height of each group of rib strips 4 at D is less than the height of the D part of the rotating plate 3. By arranging the contact panel 2 structure with a threaded structure, during use, the contact panel 2 can be placed on the outer side of the rotating plate 3 and meshed and fixed with a preset threaded hole. By rotating the rod portion 1 structure, the rotating plate 3 and the rib strips 4 are driven to rotate.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
