Referring to fig. 1 and 2, a hinge portion dust-proof member is illustrated, which includes a strip-shaped body 1 made of a flexible material, the strip-shaped body 1 is vertically disposed, and has a first groove 2 on an outer surface thereof, and the first groove 2 is distributed along a length direction of the outer surface of the strip-shaped body 1, and the main function of the dust-proof member is to facilitate accommodating a binding member when the hinge portion is sealed by using the dust-proof member, and the binding member is placed in the first groove 2 to facilitate fixing of the dust-proof member and prevent the dust-proof member and the binding member from falling off. The binding component can adopt a clamping ring or a clamping hoop. Since the dustproof member of the hinge part of the present invention is a strip-shaped structure, it can be cut according to the required length, so that the dustproof ring needs to be fixed on the installation part by other parts when in use. Meanwhile, the strip-shaped dustproof piece can be cut according to the required length, so that the dustproof piece is convenient and quick to use and replace, and the problem that the pin shaft is required to be detached when the traditional annular sealing ring is replaced, and time and labor are wasted is solved.

The inner surface of the strip-shaped body 1 is provided with strip-shaped sealing parts 3 along the length direction, the end parts of the sealing parts 3 are of a forked structure, and strip-shaped fork openings 4 are formed and distributed along the length direction of the strip-shaped body 1. Referring to fig. 3, the sealing part 3 of the bifurcated structure mainly functions to be squeezed in the fourth groove 7 between the first hinge part 8 and the second hinge part 9 to be sealed, so that the hinge part is radially sealed, and the dustproof effect is improved. And the bifurcation can make sealing part 3 more easily extruded and get into fourth recess 7 at sealed in-process, and the bifurcation position of extrusion back sealing part 3 has the trend that the bullet opened and resets, consequently can support tightly at the upper and lower surface of fourth recess 7, makes dustproof effect better. Based on this, it should be understood that the end shape of the sealing portion 3 may be selected from any one of the shapes including, but not limited to, "U" -shaped branch, "Y" -shaped branch, "V" -shaped branch, "W" -shaped branch, "C" -shaped branch, "K" -shaped branch, and the like. It should be noted that the sealing portion 3 having simple modifications, replacements, and the like similar to the above technical idea is included in the scope of the present invention.

With continued reference to fig. 2, in another preferred embodiment, the strip-shaped body 1 has second grooves 5 on its upper surface, the second grooves 5 are distributed along the length direction of the strip-shaped body 1, and the second grooves 5 are distributed on one side or both sides of the sealing part 3. The main function of the second groove 5 is to improve the radial sealing effect and the dirt holding capacity.

With continued reference to figure 2, in another preferred embodiment, between the root of said seal 3 and the upper surface of the strip-like body 1 there are third grooves 6, the third grooves 6 being distributed along the length of the strip-like body 1. The main function of the third groove 6 is to improve the axial sealing effect and the dirt holding capacity.

In another preferred embodiment, the material of the dust-proof part at the hinge part is selected from polyurethane, and compared with a rubber material, the polyurethane has better oil resistance, wear resistance and aging resistance, and is beneficial to prolonging the service life of the dust-proof part.

Finally, it should be understood that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention. Although the embodiments of the present invention have been described with reference to the accompanying drawings, it is not intended to limit the scope of the present invention, and it should be understood by those skilled in the art that various modifications and variations can be made without inventive efforts by those skilled in the art based on the technical solution of the present invention.
