Description

Technical Field

[0001] The utility model relates to a lower wire guide reinforcement structure of a wire storage rack. Background Art

[0002] ‌A wire storage rack is a device used to store and manage wires, cables, and other wires. It is mainly used to maintain the tension and neat arrangement of the wires to avoid confusion.‌

[0003] In the prior art, the bottom of the wire storage rack is a lower wire guide that can adaptively rise and fall. The lower wire guide includes a wire roller shaft. The periphery of the wire roller shaft is uniformly distributed along the axial direction with a plurality of coaxially arranged annular grooves. Circular retaining walls are coaxially embedded in the annular grooves. A winding ring groove is formed on the periphery of the wire roller shaft between two adjacent annular retaining walls. The cable is wound around the lower half of the winding ring groove. The prior art has the following deficiencies:

[0004] Since the annular retaining wall is mostly made of plastic and is relatively thin, it is easily deformed by external forces. In addition, the width of the annular groove needs to be slightly larger than the thickness of the annular retaining wall so that the inner ring of the annular retaining wall can be smoothly inserted into the annular groove. Therefore, when the cable in the winding groove deflects in the axial direction, the deflected cable easily generates an axial extrusion force F on the annular retaining wall, causing the extruded part of the annular retaining wall to be locally twisted and deformed in the axial direction. A gap B ( Figure 3 As shown in the black filled area in the figure), the thin cable can easily get stuck in gap B, causing cable obstruction. Utility Model Content

[0005] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a lower wire guide reinforcement structure for a wire storage rack.

[0006] In order to solve the above technical problems, the technical solution of the utility model is: a wire guide reinforcement structure under a wire storage rack, including a wire passing roller, and a plurality of coaxially arranged circular grooves are evenly distributed on the circumference of the wire passing roller along the axial direction, and circular retaining walls are coaxially embedded on the circular grooves. A winding ring groove is formed on the circumference of the wire passing roller between two adjacent circular retaining walls, and pads are provided on the inner top and inner bottom of the winding ring groove, and the axial ends of the pads are supported between the corresponding two adjacent circular retaining walls.

[0007] Preferably, the outer diameter of the annular retaining wall is larger than the outer diameter of the line-passing roller.

[0008] Preferably, the shape of the cushion blocks is an arc, the outer diameter of the cushion blocks is equal to the outer diameter of the annular retaining wall, and the inner diameter of the cushion blocks is greater than the outer diameter of the line roller.

[0009] Preferably, the annular retaining wall is provided with a plurality of mounting through holes along its circumference in the portion located beside the outer periphery of the line-passing roller shaft, and the pad is also provided with mounting through holes at positions corresponding to the mounting through holes of the annular retaining wall. All the annular retaining walls and the pad are locked together by screws passing through the mounting through holes and nuts threaded at both ends of the screws.

[0010] Preferably, countersunk holes are provided on the mounting through holes on the outer end surfaces of the annular retaining walls at both ends of the line-passing roller shaft, and the ends of the screw rod and the nut are both located inside the countersunk holes.

[0011] Preferably, the spacer is located in the area between two vertical sections of the cable wound around the wire roller.

[0012] Compared with the prior art, the present invention has the following beneficial effects: the wire guide reinforcement structure under the wire storage rack is provided with pads on the top and the inner bottom of the winding ring groove, and both axial ends of the pads are supported between the corresponding two adjacent circular retaining walls, which can improve the overall axial lateral support performance of the circular retaining wall, thereby improving the rigidity of the circular retaining wall. Under the support and reinforcement of the pads, the circular retaining wall is less likely to be twisted and deformed than the prior art, and gap B is less likely to be generated.

[0022] like Figures 1 to 5 As shown, this embodiment provides a wire guide reinforcement structure under the wire storage rack, including a wire passing roller 1, and a plurality of coaxially arranged circular grooves 2 are evenly distributed on the circumference of the wire passing roller along the axial direction, and circular retaining walls 3 are coaxially embedded on the circular grooves. A winding ring groove 4 is formed on the circumference of the wire passing roller between two adjacent circular retaining walls, and pads 5 are provided on the inner top and inner bottom of the winding ring groove, and the axial ends of the pads are supported between the corresponding two adjacent circular retaining walls.

[0023] In an embodiment of the present invention, the outer diameter of the annular retaining wall is greater than the outer diameter of the line-passing roller.

[0024] In the embodiment of the present invention, the shape of the cushion blocks is arc-shaped, the outer diameter of the cushion blocks is equal to the outer diameter of the annular retaining wall, and the inner diameter of the cushion blocks is greater than the outer diameter of the line roller.

[0025] In an embodiment of the present utility model, the annular retaining wall is provided with a plurality of mounting through holes 6 along its circumference at the portion located beside the outer periphery of the line-passing roller shaft, and the pad is also provided with mounting through holes at positions corresponding to the mounting through holes of the annular retaining wall. All the annular retaining walls and the pad are locked together as a whole through screws 7 passing through the mounting through holes and nuts 8 screwed at both ends of the screws.

[0026] In the embodiment of the present invention, countersunk holes 9 are provided on the mounting through holes on the outer end surfaces of the annular retaining walls at both ends of the line-passing roller shaft, and the ends of the screw rod and the nut are both located inside the countersunk holes.

[0027] In the embodiment of the present invention, the span of the spacer is located in the area between two vertical sections of the cable 10 wound around the wire roller.

[0028] In an embodiment of the present invention, the wire guide reinforcement structure under the wire storage rack is achieved by arranging pads on the top and the inner bottom of the winding ring groove, and both axial ends of the pads are supported between the corresponding two adjacent circular retaining walls.
