Description

Technical Field

[0001] This utility model relates to the field of bolt technology, and more specifically to a high-strength alloy wear-resistant bolt. Background Technology

[0002] Bolts used in industrial environments that require high strength and high wear resistance are generally made of special alloy materials, such as nickel-based alloys, cobalt-based alloys, or certain specific stainless steels. These materials have excellent mechanical properties and corrosion resistance and can withstand high operating temperatures and pressures.

[0003] During use, although bolts made of high-strength alloys have high wear resistance, they will still experience vibration wear due to factors such as vibration, especially at the point where the nut is tightened, where slight wobbling causes wear. To address this, existing patents, such as "a bolt for a power steering system for electric vehicles" (application number: CN201920953162.5), use anti-loosening washers at the nut as the tightening point to improve wear resistance and installation stability at that location.

[0004] However, the anti-loosening washer used only provides support and stability in the direction of the nut, which has the disadvantage of insufficient support surface and inadequate stability. Utility Model Content

[0005] The purpose of this utility model is to provide a high-strength alloy wear-resistant bolt in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] This utility model proposes a high-strength alloy wear-resistant bolt, comprising:

[0008] Bolt body and wear-reducing components installed on it;

[0009] The wear-reducing component includes;

[0010] A washer is fitted over the threaded part of the bolt body, with the top of the washer fitting against the bottom of the nut on the bolt body.

[0011] The pressure strip is fixed at the bottom of the washer and close to the opening of the washer. The ends of the pressure strip face up and down, and the side of the pressure strip facing away from the bolt body gradually moves away from the bolt body from bottom to top.

[0012] As a preferred embodiment of this utility model, the pressure strip gradually increases in size from bottom to top.

[0013] As a preferred embodiment of this utility model, the pressure strip is provided in multiple sets and is evenly distributed in a ring outside the bolt body.

[0014] As a preferred embodiment of this utility model, the wear-reducing component further includes;

[0015] Vertical strips, which are fixed to the pressure strips;

[0016] The vertical groove is located on the bolt body and is used for vertical strips to be fitted and embedded.

[0017] As a preferred embodiment of this utility model, the wear-reducing component further includes;

[0018] A horizontal bar, which is fixed to the top of the washer;

[0019] A transverse groove is provided on the nut of the bolt body, and a transverse bar is fitted and embedded in the transverse groove.

[0020] As a preferred embodiment of this utility model, one end of the horizontal bar faces the opening of the washer.

[0021] As a preferred technical solution of this utility model, the horizontal bar is provided in multiple sets and is evenly distributed in a ring around the opening of the washer.

[0022] The beneficial effects of this utility model are as follows:

[0023] By inserting the screw into the mounting hole until it contacts the pressure strip, the upward expanding shape of the pressure strip provides flexible clamping when it is inserted into the mounting hole, with the clamping force increasing as it goes deeper. When used in conjunction with the gasket, it provides clamping from multiple directions to greatly improve stability. Furthermore, the gasket fixes the pressure strip, and the installation of the pressure strip is completed when installing the gasket, making it convenient to use. The vertical bars, vertical grooves, horizontal bars, and horizontal grooves further enhance the stability of the gasket and pressure strip in their positions. Attached Figure Description

[0026] Reference numerals: Bolt body-1, wear-reducing component-2, washer-21, pressure strip-22, vertical strip-23, vertical groove-24, horizontal strip-25, horizontal groove-26. Detailed Implementation Example 1:

[0027] like Figures 1-2 As shown in this embodiment, a high-strength alloy wear-resistant bolt is proposed, comprising:

[0028] The bolt body 1 and the wear-reducing component 2 installed on it, the bolt body 1 is composed of an upper nut and a lower screw;

[0029] The wear-reducing component 2 includes:

[0030] Washer 21 is fitted around the bolt body 1, and the top of washer 21 is in contact with the bottom of the nut of bolt body 1; washer 21 is attached to the bottom of the nut, and washer 21 is surrounding the outside of the bolt body.

[0031] Pressure strip 22 is fixed at the bottom of washer 21 and is close to the opening of washer 21. The ends of pressure strip 22 face up and down. The side of pressure strip 22 facing away from the bolt of bolt body 1 gradually moves away from the bolt of bolt body 1 from bottom to top. Pressure strip 22 and washer 21 are made of flexible material (such as rubber).

[0032] When in use, the screw is inserted into the mounting hole (not shown in the figure) until the pressure strip 22 contacts it. The upward expansion shape of the pressure strip 22 provides flexible clamping when it is inserted into the mounting hole, and the clamping force increases as it goes deeper. When used in conjunction with the fit of the washer 21, it can provide clamping from multiple directions to greatly improve stability. Furthermore, the washer 21 fixes the pressure strip 22, and the installation of the pressure strip 22 can be completed when installing the washer 21, making it convenient to use.

[0033] The pressure strip 22 gradually increases in size from bottom to top, as shown in the figure. The side closer to the screw is vertical, while the side farther from the screw gradually extends upwards in a direction away from the screw. This structure can provide better support.

[0034] Among them, the pressure strip 22 is provided in multiple sets and is evenly distributed in a ring outside the bolt body 1, such as Figure 1 As shown, two sets of pressure strips 22 are symmetrically arranged on the left and right sides, which can provide balanced support when providing compression and better stability. Example 2:

[0035] like Figures 1-2 As shown, the difference between this embodiment and Embodiment 1 is that the wear reduction component 2 further includes;

[0036] Vertical bar 23 is fixed to pressure bar 22;

[0037] The vertical groove 24 is provided on the threaded rod of the bolt body 1, and the vertical strip 23 is fitted and embedded in the vertical groove 24. The vertical strip 23 is made of a flexible material (such as rubber).

[0038] like Figure 1As shown, a recessed vertical groove 24 is provided between the upper side of the screw and the bottom of the nut. By embedding the vertical groove 24 into the groove, a stable and convenient position for the washer 21 and the pressure strip 22 can be provided. At the same time, the pressure strip 22 is partially inserted into the vertical groove 24, especially the bottom end of the pressure strip 22 is completely inside the vertical groove 24, so it can be easily inserted and pressed into the hole mentioned above when in use. Example 3:

[0039] like Figures 1-2 As shown, its difference from Embodiment 1 or 2 is that: the wear reduction component 2 also includes;

[0040] A horizontal bar 25 is fixed to the top of the washer 21;

[0041] A transverse groove 26 is provided on the nut of the bolt body 1, and a transverse bar 25 is fitted and embedded in the transverse groove 26. The transverse bar 25 is made of a flexible material (such as rubber).

[0042] The horizontal bar 25 at the top of the washer 21 is inserted into the horizontal groove 26, which can provide positional limitation. When the washer 21 is subjected to rotational force during use, its position can be stabilized better.

[0043] One end of the horizontal bar 25 faces the opening of the washer 21; for example... Figure 1 As shown, the ends of the horizontal bar 25 are oriented left and right and one end is parallel to the center line of the screw, which provides good support for the washer 21 when it is subjected to rotational force and can further improve positional stability.

[0044] Among them, the horizontal bars 25 are provided in multiple sets and are evenly distributed in a ring around the opening of the washer 21. The number of bars is increased and the support positions are reasonably set to improve the support strength.
