Description

Technical Field

[0001] The utility model relates to the technical field of drag chains, in particular to a bellows dust-free drag chain shell. Background Art

[0002] Drag chains, also known as cable protection drag chains, are devices that bind cables or wires or air and hydraulic pipes to facilitate their rotation and movement. Drag chains are used in reciprocating motion situations and can pull and protect built-in cables, oil pipes, air pipes, water pipes, etc. Drag chains have been widely used in CNC machine tools, electronic equipment, glass machinery, injection molding machine manipulators, handling machinery, plastic machinery, lifting equipment, woodworking machinery, automotive industry, industrial vehicles, metal processing machines, machine tools, casting machinery, port equipment, flat panel display equipment, semiconductor equipment and other industries.

[0003] Plastic drag chains are generally used in automation equipment. The advantage of using plastic drag chains is that they are light in weight and easy to move and operate automation equipment. In order to adapt to operations in clean rooms and vacuum environments, dust-free drag chains, also known as clean room drag chains, are needed. They are used in clean rooms to bear electrical connection equipment and loads. They have the characteristics of friction resistance, no gas release, no dust accumulation, acid and alkali resistance and aging resistance. They are usually sleeved on the surface of cable air pipes for sealing and dust prevention. Before installation, it is necessary to ensure that the internal cable air pipe cannot be bent, and the radius of the dust-free drag chain cannot be less than the cable diameter.

[0004] The existing dust-free drag chain housing is usually formed by buckling two upper and lower shells. When in use, when the cable air pipe is placed in the drag chain and needs to be closed, the side strips of the two shells need to be quickly buckled together. The buckle structure is generally used to achieve the side strips. When a single buckle is used for a long time, it is easy to loosen and break. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a bellows dust-free drag chain housing, aiming to solve the technical defects of at least one existing dust-free drag chain in the background technology.

[0006] In order to solve the above technical problems, the technical solution of the utility model is as follows:

[0007] The utility model provides a bellows dust-free drag chain housing, comprising an upper shell body and a lower shell body, wherein the outer sides of the upper shell body and the lower shell body are respectively provided with buckling edge strips along the length direction, and alignment posts and alignment holes are respectively provided between the two buckling edge strips that are abutted against each other, and a plurality of clips and clip holes are also evenly provided between the two buckling edge strips that are abutted against each other along the length direction, the alignment posts enter into the alignment holes, and the clips enter into the clip holes.

[0008] Furthermore, the surfaces of the upper shell and the lower shell are respectively provided with corrugated parts, and tubular cavities are formed in the upper shell and the lower shell.

[0009] Furthermore, the upper shell and the lower shell are buckled together along the length direction to form a U-shaped structure, including a curved portion, and two ends of the curved portion, at least one of which is provided with a straight portion, so that the drag chain maintains the shape of the cable in a natural state.

[0010] Furthermore, the straight portion and the curved portion are both formed by buckling the upper shell and the lower shell along the length direction, and opposite ends of the straight portion and the curved portion are respectively provided with fusion ports for connection in a melting manner.

[0011] Furthermore, the alignment posts and the alignment holes on the two mutually fitted buckling side strips correspond to each other and are arranged in an interlaced manner.

[0012] By adopting the above technical solution, the bellows dust-free drag chain housing of the utility model embodiment includes an upper shell and a lower shell. The outer sides of the upper shell and the lower shell are respectively provided with buckle side strips along the length direction. Alignment posts and alignment holes are respectively provided between the two buckle side strips that fit each other. A plurality of clips and clamping holes are also evenly provided between the two buckle side strips that fit each other along the length direction. The alignment posts enter the alignment holes, and the clips enter the clamping holes. Since the buckle side strips are provided on the outer sides of the upper shell and the lower shell, the space of the tube cavity is expanded. In addition, the use of clips and clamping holes increases a structure similar to a stapler. When used for a long time, clips are stapled in at certain intervals to prevent the drag chain from cracking during long-term use, thereby increasing the stability of the product.
