[0002] High-speed rail dust covers are protective structures used to protect the shock absorbers of high-speed trains. The main functions of dust covers are to prevent wind and dust, water, oil, and acid and alkali, while also having corrosion resistance and tensile strength. Dust covers are usually made of materials such as rubber, plastic cloth, three-proof cloth, and polyurethane sheets, and are shaped by high-frequency heat sealing or compression.

[0003] In actual use, the existing high-speed rail dust covers are fitted and fixed to the shock absorbers, lacking a limiting and protective structure, resulting in poor stability and inadequate sealing at the bottom. This paper proposes a high-speed rail dust cover with better installation stability to solve the above problems. Utility Model Content

[0004] In view of the shortcomings and defects in the existing technology, this utility model proposes a high-speed rail dust cover with good installation stability, which solves the technical problems in the background technology that the dust cover of the existing high-speed rail dust cover is sleeved and fixed on the shock absorber during actual use, lacks a limiting and protective structure, has poor stability, and has poor sealing effect at the bottom of the dust cover.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-speed rail dust cover with good installation stability includes a dust cover body. The lower end of the dust cover body is provided with an annular base. Two bolts are inserted through the annular inner wall of the annular base. Each of the two bolts is provided with a clamping block at one end inside the annular base. The bolts and clamping blocks are movably engaged. Buffer components are provided on the opposite side walls of the two clamping blocks. Several arc-shaped limiting protrusions are fixedly connected to the annular inner wall of the annular base near the lower end.

[0007] Preferably, the annular base has two symmetrically distributed threaded holes on its annular inner wall, and the two bolts are threaded through the two threaded holes respectively.

[0008] Preferably, each of the two clamping blocks has a circular slot on the side wall opposite the bolt, and each of the two circular slots has a rectangular protrusion on the inner wall opposite the bolt. Each of the two bolts has a rectangular slot at one end located inside the annular base. The two bolts are respectively inserted into the two circular slots, and the two rectangular protrusions are respectively inserted into the two rectangular slots.

[0009] Preferably, the rectangular protrusion and the clamping block are integrally formed.

[0010] Preferably, the buffer assembly includes arc-shaped buffer pads fixedly connected to the opposite sidewalls of two clamping blocks, each of the two arc-shaped buffer pads having a cavity, and the arc-shaped buffer pads being wear-resistant rubber products.

[0019] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3 A high-speed rail dust cover with good installation stability includes a dust cover body 1. The lower end of the dust cover body 1 is provided with an annular base 2. Two bolts 3 are provided through the annular inner wall of the annular base 2. Two threaded holes 6 are provided on the annular inner wall of the annular base 2. The two bolts 3 are respectively threaded through the two threaded holes 6. Tightening the bolts 3 in conjunction with the threaded holes 6 causes the clamping block 4 to move.

[0022] Each of the two bolts 3 has a clamping block 4 at one end inside the annular base 2. The bolts 3 and the clamping blocks 4 are movably engaged. Each of the two clamping blocks 4 has a circular slot 7 on the side wall opposite to the bolts 3. Each of the two circular slots 7 has a rectangular protrusion 8 on the inner wall opposite to the bolts 3. Each of the two bolts 3 has a rectangular groove 9 at one end inside the annular base 2. The two bolts 3 are respectively inserted into the two circular slots 7, and the two rectangular protrusions 8 are respectively inserted into the two rectangular grooves 9. The rectangular protrusions 8 and the clamping blocks 4 are integrally formed. The two clamping blocks 4 are respectively connected to the two bolts 3, so that the two bolts 3 are respectively inserted into the circular slots 7 on the two clamping blocks 4, and the rectangular protrusions 8 are inserted into the rectangular grooves 9. This effectively clamps and positions the clamping blocks 4 on the bolts 3. The structure is simple and easy to replace.

[0023] Both clamping blocks 4 have buffer components on their opposite sidewalls. Each buffer component includes an arc-shaped buffer pad 10 fixedly connected to the opposite sidewalls of the two clamping blocks 4. Each arc-shaped buffer pad 10 has a cavity 11. The arc-shaped buffer pad 10 is made of wear-resistant rubber. The dust cover body 1 is fitted onto the high-speed rail shock absorber. Tightening the two bolts 3, which engage with the threaded holes 6, causes the two clamping blocks 4 to press against and tighten against the high-speed rail shock absorber. This allows the arc-shaped buffer pads 10 on the two clamping blocks 4, in conjunction with the cavities 11, to press and position the high-speed rail shock absorber, effectively... The arc-shaped buffer pad 10 provides limiting protection and improves structural stability. Several arc-shaped limiting protrusions 5 are fixedly connected to the inner wall of the annular base 2 near the lower end. The four arc-shaped limiting protrusions 5 are arranged in a cross shape. The arc-shaped limiting protrusions 5 and the annular base 2 are integrally formed. When the inner wall of the dust cover body 1 is close to the high-speed rail shock absorber, the four cross-shaped arc-shaped limiting protrusions 5 abut against and press against the high-speed rail shock absorber and move closer to each other, effectively sealing the bottom of the dust cover body 1 and improving the sealing effect.

[0024] In use, the two clamping blocks 4 are respectively connected to the two bolts 3, so that the two bolts 3 are respectively inserted into the circular slots 7 on the two clamping blocks 4, and the rectangular protrusions 8 are inserted into the rectangular slots 9. The dust cover body 1 is sleeved on the high-speed rail shock absorber. Tightening the two bolts 3 in conjunction with the threaded holes 6 causes the two clamping blocks 4 to abut and press against the high-speed rail shock absorber, so that the arc-shaped buffer pads 10 on the two clamping blocks 4, together with the cavity 11, press and position the high-speed rail shock absorber, effectively providing limiting protection for the arc-shaped buffer pads 10 and improving structural stability. When the inner wall of the dust cover body 1 is close to the high-speed rail shock absorber, the four cross-shaped arc-shaped limiting protrusions 5 abut against and press against the high-speed rail shock absorber and move closer to each other, effectively providing a seal to the bottom of the dust cover body 1 and improving the sealing effect.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
