Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a CPS load force drag chain is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A CPS load force drag chain includes two connecting plates installed at both ends of the drag chain main body. Three PVC pipe conduits are fixedly connected in sequence between the two connecting plates, and all three PVC pipe conduits are laid in the drag chain main body;

[0007] Cables adapted to each other are provided in all three PVC pipe conduits. Protective shells are fixedly connected to both connecting plates, and an anti-detachment structure and a heat dissipation structure are provided in both protective shells;

[0008] The anti-detachment structure includes three centering and clamping components distributed at equal distances, a transmission shaft rotatably installed in the protective shell, and a guiding shaft fixedly connected in the protective shell.

[0009] As a preferred one, the centering and clamping component includes a bidirectional thread unit arranged on the transmission shaft, two centering rods symmetrically screwed on two opposite thread ends of the bidirectional thread unit, and two C-shaped clamps symmetrically fixed on the outer walls of adjacent sides of the two centering rods.

[0010] As a preferred one, guiding holes are opened on both centering rods, and the inner walls of the two guiding holes are slidably connected to the outer wall of the guiding shaft.

[0011] As a preferred one, an anti-slip rotating cap is fixedly connected to the outer wall of one end of the transmission shaft.

[0012] As a preferred embodiment, the heat dissipation structure includes three micro heat dissipation fans installed on the top of the protective shell and distributed at equal intervals, and a plurality of heat dissipation openings opened on one side of the protective shell and distributed at equal intervals.

The upper ends of three cables respectively penetrate through the three wire passing holes located above, and the lower ends of the three cables respectively penetrate through the three wire passing holes located below.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. An anti - detachment structure is provided. By operating the drive shaft through the anti - slip cap, the three bidirectional thread units on the drive shaft will rotate. Under the guidance of the guide shaft, the three groups of centering rods connected by threads will drive the three groups of C - type clamps to move closer to the center. This facilitates clamping three cables at one time and can effectively reduce the situation that the cable connections are prone to looseness and detachment due to unexpected circumstances.

[0016] 2. A heat dissipation structure is provided. The heat generated inside the protective shell is discharged to the outside from the heat dissipation opening area by the wind generated by the operation of the three micro heat dissipation fans, so as to achieve the effect of cooling the cables.
