Description

Technical Field

[0001] This utility model relates to the field of wire harness winding technology, and in particular to a wire harness winding device for an electronic equipment display stand. Background Technology

[0002] A wire harness, also known as a wire bundle or cable harness, refers to a wire assembly in which multiple wires or cables are bundled together and secured as a whole by wrapping them with materials such as plastic or rubber. Wire harnesses can connect multiple devices and are an indispensable part of modern industry and transportation. A wire harness typically consists of conductors, insulation, an outer sheath, connectors, plugs, and protective sleeves. The conductors are the main body of the wire harness, the insulation layer is used to cover the conductors and protect them from external damage, and the outer sheath is used to bind and protect the entire wire harness. After the wire harness is no longer in use, a wire harness winding device is usually used to wind and protect it. Wire harness winding is a method of collecting and bundling wire harnesses. During wire harness winding, in order to accurately collect and secure the wire harness, the wire harness conductor reel needs to be disassembled and adjusted.

[0003] The above-mentioned existing technical solutions have the following drawbacks: when using wire harnesses, it is difficult to control the length of the wire harnesses, and when winding the wire harnesses, manual winding is required to achieve the purpose of recycling. Utility Model Content

[0004] The purpose of this invention is to provide a wire harness winding device for electronic equipment display stands to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A wire harness winding device for an electronic device display stand includes:

[0007] The outer shell is a cylindrical shell with its top end completely open. A wire through-hole is provided on one side of the outer shell. A cylinder integrally formed with the outer shell is provided at the center of the bottom of the outer shell. A downward through-hole is provided at the center of the top of the cylinder, and both sides of the through-hole penetrate the cylinder.

[0008] A coil spring is sleeved on a cylinder, and the positioning plate of the coil spring is embedded in the cylinder slot. A protective shell is sleeved on the outer ring of the coil spring. The coil spring is used to make the protective shell rotate axially around the axis of the cylinder. A disc is sleeved at the middle position of the outer side of the protective shell. The disc is used to divide the space between the outer side of the protective shell and the inside of the outer shell into upper and lower chambers.

[0009] The cover plate is a thin, annular sheet. The end cap is fixedly installed on the top of the outer shell. A cable is wound around the outer side of the top of the protective shell. One end of the cable passes through the cable insertion port, and the other end of the cable passes through the center of the cover plate.

[0010] By adopting the above technical solution, the wire harness enters from the wire inlet on one side of the outer shell and is wound onto the disc, and then exits from the center of the cover plate. When the wire harness reaches the target length, the coil spring will drive the disc to rotate, thereby controlling the length of the wire harness.

[0011] In a further embodiment, a locking structure is included, which is disposed inside the housing in a cavity located below the disk. The locking structure includes a sleeve fitted onto the bottom end of the housing and a locking block, one end of which is rotatably connected to the inner wall of the housing.

[0012] In a further embodiment, the inner bottom of the housing is provided with a limiting protrusion corresponding to the locking block, the limiting protrusion being used to limit the rotation range of the locking block.

[0013] In a further embodiment, the inner bottom of the outer casing is provided with a plurality of reinforcing ribs evenly distributed axially.

[0014] In a further embodiment, the protective shell is a cylindrical shell with its bottom end completely open, and a clearance groove for avoiding the cylinder is provided at the center of the inner top of the protective shell.

[0015] In a further embodiment, a raised ring corresponding to the outer ring of the coil spring is provided on the inner top periphery of the outer shell, the raised ring being used to create a gap between the top of the coil spring and the inner top of the protective shell.

[0016] By adopting the above technical solution, the wire harness winding device is placed horizontally. When the wire harness is pulled out, the coil spring stores energy, and the wire harness naturally winds up under the action of the coil spring. When the wire harness reaches the target length, it needs to be locked. At this time, the wire harness winding device is rotated 90 degrees vertically to achieve vertical placement of the wire harness winding device, with the locking block located at the top of the notch. Under the action of gravity, the bottom of the locking block is driven to engage with the inside of the notch, firmly locking the sleeve inside the outer shell, preventing the sleeve from rotating, and thus preventing the wire harness from being pulled out, achieving the purpose of locking. When it is necessary to retract the wire harness, the wire harness winding device is rotated 180 degrees vertically, and then the wire harness is stretched to facilitate the separation of the notch and the locking block. Finally, the locking block completely separates from the notch under the action of gravity, thereby achieving the purpose of winding under the action of the coil spring.

[0017] In a further embodiment, a triangular body is provided at the inlet of the cover plate, and the interior of the triangular body is a hollow structure.

[0018] By adopting the above technical solution, when the device is operating and the wires are being fed in, the triangular body guides the wire harness, thus avoiding device malfunctions caused by the wire harness being fed in too quickly.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. The ratchet locking structure maintains a locked state at a specific position, preventing reverse movement and providing a stable wire harness length adjustment function. The caliper and mounting slot notch adapt to the deformation of the coil spring and control the rotation speed. The bottom reinforcing rib enhances structural strength and disperses stress to improve performance. With the bottom-mounted coil spring and ratchet locking structure, the coil spring stores energy when the wire harness is pulled out. When the desired length is reached and the wire harness is pulled out, the shaft rotates under the action of the coil spring and is locked by the ratchet locking structure, stopping the wire harness movement. When the wire harness is finished and being wound up, the ratchet locking structure releases its stored energy, causing the shaft to wind the wire harness back. Attached Figure Description

[0028] Example 1:

[0029] like Figure 1-4 As shown, a wire harness winding device for an electronic device display stand includes:

[0030] The outer shell 1 has a completely open top and a wire-passing port on one side. A cylinder 2 integrally formed with the outer shell 1 is located at the center of the bottom of the outer shell 1. A downward-through groove is located at the center of the top of the cylinder 2, and both sides of the groove penetrate the cylinder 2. A coil spring 3 is sleeved on the cylinder 2, and the positioning piece of the coil spring 3 is embedded in the groove of the cylinder 2. A protective shell 4 is sleeved on the outer ring of the coil spring 3. The coil spring 3 is used to make the protective shell 4 rotate axially around the axis of the cylinder 2. A disc 5 is sleeved at the center of the outer side of the protective shell 4. The disc 5 is used to divide the space between the outer side of the protective shell 4 and the interior of the outer shell 1 into upper and lower chambers. A cover plate 6 is a thin, annular sheet. The cover plate 6 is fixedly installed on the top of the outer shell 1 by bolts.

[0031] like Figure 2 As shown, the coil spring 3 is sleeved on the cylinder 2, and the positioning plate of the coil spring 3 is embedded in the groove of the cylinder. The outer ring of the coil spring 3 is sleeved with a protective shell 4. The coil spring 3 is used to make the protective shell 4 rotate axially around the axis of the cylinder. A metal caliper is fixedly installed at the bottom of the ring by bolts. The metal caliper is slidably installed with the protective shell 4 of the coil spring 3. The protective shell 4 of the coil spring 3 has three notches on the outside to accommodate the deformation of the coil spring 3 and to cooperate with the metal caliper to control the rotation speed. The locking structure 7 is set in the cavity inside the outer shell 1 located on the lower side of the disc 5. The locking structure 7 includes a sleeve 71 sleeved on the bottom end of the outer shell and a locking block 72. One end of the locking block 72 is rotatably connected to the inner wall of the outer shell 1.

[0032] like Figure 2-3 As shown, the cover plate 6 is a thin, circular sheet. The cover plate 6 is fixedly installed on the top of the outer casing by bolts. When the wire harness is wound, the wire harness enters from the wire inlet on one side of the outer casing, is wound around the disc 5, and then passes out from the center of the cover plate 6 with the assistance of the coil spring 3. A triangular body 11 is provided at the wire inlet inside the cover plate 6. When the device is operating and the wire is fed in, the triangular body 11 guides the wire harness to avoid device failure caused by the wire harness entering too quickly.

[0033] like Figure 2-4 As shown, the outer shell 1 is a cylindrical shell. The bottom of the inner shell 1 is provided with a limiting protrusion 8 corresponding to the locking block 72. The limiting protrusion 8 is used to limit the rotation range of the locking block 72. Multiple reinforcing ribs 9 are evenly arranged axially on the bottom of the inner shell 1. Without affecting the normal operation of the device or increasing the wall thickness, the strength and rigidity of the device are enhanced, and the stress unevenness caused by the difference in wall thickness is overcome. By increasing the local strength and rigidity, the load-bearing capacity and stability of the overall structure are improved. The stress is effectively dispersed, avoiding local stress concentration and reducing the risk of deformation and breakage. The inner top periphery of the outer shell 1 is provided with a protruding ring 12 corresponding to the outer ring of the coil spring 3. The protruding ring 12 is used to create a gap between the top of the coil spring 3 and the inner top of the protective shell 4, so as to avoid wear during the operation of the device.

[0034] Specific implementation process: The positioning piece at the center of the coil spring 3 is embedded into the slot of the cylinder 2 at the center of the bottom of the outer casing 1. A protective shell 4 is fitted over the coil spring 3, and a ring is fitted at the middle of the outer side of the protective shell 4. The disc 5 is used to divide the space between the outer side of the protective shell 4 and the interior of the outer casing 1 into upper and lower chambers. The cover plate 6 is fixed to the top of the outer casing 1 with bolts. By adopting the above technical solution, the wire harness winding device is placed horizontally. When the wire harness is pulled out, the coil spring 3 will store energy, and the wire harness will naturally wind up under the action of the coil spring 3. When the wire harness reaches the target length, it needs to be locked. At this time, Next, rotate the wire harness winding device 90 degrees vertically to achieve vertical placement of the wire harness winding device, with the locking block 72 located at the top of the notch. Under the action of gravity, the bottom of the locking block 72 is driven to engage with the inside of the notch, firmly locking the sleeve 71 inside the outer casing 1, preventing the sleeve 71 from rotating and thus preventing the wire harness from being pulled out, achieving the locking purpose. When it is necessary to retract the wire harness, rotate the wire harness winding device 180 degrees vertically, and then stretch the wire harness to facilitate the separation of the notch from the locking block 72. Finally, the locking block 72 completely separates from the notch under the action of gravity, thereby achieving the winding purpose under the action of the coil spring 3. Because the coil spring 3 is fixedly installed inside the protective shell 4 close to the outer shell 1, a convex ring 12 corresponding to the outer ring of the coil spring 3 is provided on the inner top periphery of the outer shell 1. The convex ring 12 is used to create a gap between the top of the coil spring 3 and the inner top of the outer shell 1 to reduce friction damage to the device. The triangular body 11 provided at the wire outlet of the cover plate 6 guides the wire harness to avoid jamming.
