The dustproof steel belt mounting block comprises a mounting block body, which is composed of two side surfaces and an upper top surface. The two side surfaces and the upper top surface form a groove. The side surfaces are provided with anti-skid stripes. The edges of the upper top surface and the two side surfaces are in a large R angle structure. The two ends of the groove are in a large chamfer structure. The dustproof steel belt mounting block can be integrally injection molded, and has the characteristics of small volume, simple structure, short production cycle, low cost and convenient use.

[0003] In the linear guide rail dustproof steel belt mounting block in the above-mentioned patent, in actual operation, in order to improve the stability of the connection between the two ends of the steel belt and the guide rail, a lengthening part is usually added to the two ends of the steel belt and two notches are cut. The lengthening part is provided with a mounting hole in advance, and the lengthening part is fixed to the end of the guide rail through bolts. However, there are the following technical problems. The lengthening part and the notch part are prone to bulging and gaps with the guide rail. Dust and impurities can easily enter between the guide rail and the steel belt through the bulges and gaps for a long time, resulting in a decrease in the precision of the guide rail. Therefore, it is necessary to solve the problem of easy bulging and gap between the end of the steel belt and the guide rail.
