Problems solved by technology

Although this method is fastened, it occupies a part of the space due to the existence of rivet heads or bolt heads. Therefore, some structures that require sliding elements to be close to each other when shrinking (such as the PVC skeleton in the leather cavity) shrink too much, reaching less than design-required, and thus cannot be used

Embodiment Construction

[0022] The structure and application of the present invention will be described in detail below by taking the sliding friction slider made of wear-resistant plastic as an example.

[0023] see figure 1 , where 1 is the bottom edge of the slider, 2 is the side wall of the slider, and 3 is the cylindrical pin. The plastic sliding friction slider is a one-piece structure formed by wear-resistant plastic injection molding process, and its basic shape is U-shaped. A cylinder-shaped pin 3 perpendicular to the side walls is provided on the inner sides of the two side walls 2 of the slider. For the need of demoulding, a gap of corresponding size is opened on the side wall 2 opposite to the pin 3, and the pins 3 are arranged staggeredly on the inner surface of the two side walls 2 of the slider at a certain interval, and a section of intact space is left between the pins 3. Side wall 2 to maintain the clamping force of the two walls of the slider. The pins 3 can also be evenly arran...

Abstract

The sliding rubbing block includes two bottom and two perpendicular side walls constituting one U-shaped sliding chute. The U-shaped sliding chute features that its one or two side walls are provided with columnar pins to lock the sliding element. The columnar pins are perpendicular to the side walls, have height greater than the interval between the two side walls, and are corresponding to notches in the opposite side wall. The present invention is one self-locking structure and is convenient in installation and replacement and reliable.

Description

technical field [0001] The invention belongs to the contact type sliding friction protection parts, especially the flexible protection device installed on the machinery and instruments, which is a leather cavity (commonly known as a leather tiger) and a telescopic steel protection cover whose sheet-shaped support skeleton is in contact with the track or sliding surface. Sliding friction sliders on the sides. Background technique [0002] Sliding friction In the mechanical structure, there are often contact sliding frictions between two mechanical elements, one static and one dynamic or relative movement. Especially in the flexible protective device of machinery and instrument, the leather cavity (commonly known as the leather tiger) and the telescopic steel protective cover are all designed and manufactured in the contact sliding friction mode. In this way, the following movement modes appear: one or several thin-plate elements (usually PVC supporting frame or aluminum allo...
