Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, specifically to a dragging auxiliary device for laying electronic wire harnesses. Background Technology

[0002] Wire harnesses are wiring components that connect various electrical devices in a circuit. They consist of insulating sheaths, terminals, wires, and insulating wrapping materials. To improve the convenience of laying wire harnesses during interior decoration, they are often placed on multiple rotating rollers for easy dragging. However, the rotating rollers do not have any limit on the wire harnesses, which can easily cause them to fall off during dragging. Moreover, when the wire harnesses need to be dragged to higher locations such as the ceiling, the rotating rollers cannot provide any assistance. Therefore, there is an urgent need for a dragging assistance device for laying electronic wire harnesses. Utility Model Content

[0011] The limiting frame consists of two frames, which are rotatably mounted on the left and right sides inside the fixed frame via shafts and bearings, respectively. A guide block is fixedly mounted on the limiting frame and is movably mounted in a guide groove on the movable frame.

Detailed Implementation

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figures 1-4 As shown, this specific embodiment adopts the following technical solution: It includes a support base 1, a support frame 2, and a first roller 3. The support frame 2 is fixedly installed on the front and rear sides of the upper part of the support base 1 by bolts. The first roller 3 is rotatably connected to the left and right sides between the two support frames 2 by shafts and bearings. Rotating rods 16 are rotatably connected to the vertical grooves opened at the corners on both sides of the support frame 2 by shafts and bearings, so as to avoid the wire harness on the first roller 3 from rubbing against the corners of the support frame 2 during the dragging process, thus preventing the wire harness from being worn.

[0026] It also includes:

[0027] Two connecting blocks 4 are respectively located above two support frames 2. A vertical rod 5 is fixedly installed at the bottom of the connecting block 4 and is movably inserted into the support frame 2. Guide rods 14 are fixedly installed on the left and right sides of the lower part of the connecting block 4 by bolts. The guide rods 14 are movably inserted into the support frame 2 and can guide the up and down movement of the connecting block 4, thereby improving the movement stability of the connecting block 4. A synchronous rod 6 is rotatably connected between the two support frames 2 by bearings. The synchronous rod 6 is located between the two No. 1 rollers 3. A reinforcing strip 13 is rotatably sleeved on the synchronous rod 6 by bearings. The reinforcing strip 13 is fixedly installed on the upper part of the support seat 1 by bolts, and the two ends of the reinforcing strip 13 are fixedly connected to the two support frames 2 respectively. The reinforcing strip 13 can not only improve the connection stability of the support frame 2 on the support seat 1, but also realize the connection between the two support frames 2, thereby further improving the support stability of the support frame 2.

[0028] Two threaded rods 7 are respectively rotatably mounted in two support frames 2 via bearings. The upper end of the threaded rod 7 is inserted into the vertical rod 5 via threads, and the lower end of the threaded rod 7 is connected to the synchronous rod 6 via a bevel gear pair.

[0029] A first connecting frame 8 is rotatably connected to the rear connecting block 4 via a hinge. A second connecting frame 9 is abutted on the front connecting block 4. A second roller 10 is rotatably connected between the first connecting frame 8 and the second connecting frame 9 via a shaft and bearing. A limiting mechanism 11 is provided on the second connecting frame 9. A connecting handle 15 is provided above the second roller 10. The two ends of the connecting handle 15 are respectively connected to the first connecting frame 8 and the second connecting frame 9. The connecting handle 15 can not only realize the connection between the first connecting frame 8 and the second connecting frame 9, improving the overall structural strength of the device, but also facilitate the ease of picking up and moving the device.

[0030] The limiting mechanism 11 includes:

[0031] The fixed frame 11-1 is fixedly mounted on the front side wall of the second connecting frame 9 by bolts. The movable frame 11-2 is movably mounted inside the fixed frame 11-1. The control rod 11-3 is movably inserted into the fixed frame 11-1, and the lower end of the control rod 11-3 is fixedly connected to the movable frame 11-2.

[0032] Limiting frame 11-4, there are two limiting frames 11-4, which are rotatably set on the left and right sides inside the fixed frame 11-1 respectively by shaft and bearing. Guide block 11-5 is fixedly set on the limiting frame 11-4, and guide block 11-5 is movably set in the guide groove 12 opened on the movable frame 11-2.

[0033] Spring 11-6, there are two springs 11-6, which are respectively fixedly installed on the left and right sides inside the fixed frame 11-1, and one end of spring 11-6 is fixedly connected to the limiting frame 11-4. The left and right sides of the front side wall of the front connecting block 4 are fixedly installed with limiting blocks 11-7 by bolts, and the limiting frame 11-4 is stuck on the limiting blocks 11-7.

[0034] When using this utility model, press down the control lever 11-3. The control lever 11-3 drives the movable frame 11-2 to move downward. The movement of the guide block 11-5 within the guide groove 12 causes the limiting frames 11-4 on both sides to simultaneously reverse and disengage from the limiting block 11-7, compressing the spring 11-6. Then, the connecting handle 15 can be used to flip the first connecting frame 8 and the second connecting frame 9 backward. At this time, the second roller 10 will also flip backward synchronously with the first connecting frame 8 and the second connecting frame 9, and the second connecting frame 9 will disengage from the front connecting block 4. The wire harness can then be placed on the two first rollers 3, and the connecting handle 15 can be used to move the first connecting frame 8 and the second connecting frame 9 forward. Flip the connector so that the second connecting frame 9 re-engages with the front connecting block 4. Then release the control lever 11-3, causing the spring 11-6 to return to its original position and push the limit frame 11-4 to flip back to its initial position. This allows the limit frame 11-4 to be locked onto the limit block 11-7, completing the limiting and fixing of the second connecting frame 9 on the front connecting block 4. Afterward, the synchronous rod 6 can be rotated, and the transmission of the bevel gear pair can be used to drive the synchronous rotation of the threaded rods 7 on both sides. This allows the vertical rod 5 to move the connecting block 4 up and down, thereby adjusting the height of the second roller 10 and adapting it to different specifications of wire harnesses. During the dragging of the wire harness, the first roller 3 and the second roller 10 can rotate together, preventing the wire harness from directly contacting and rubbing against the ground during dragging.

[0035] Compared with the prior art, the beneficial effects of this utility model are:

[0036] With the cooperation of support frame 2, connecting block 4, first connecting frame 8, second connecting frame 9, second roller 10 and limiting mechanism 11, the electronic wire harness can be limited to prevent the electronic wire harness from detaching from the device during any dragging process.

[0037] By cooperating with the vertical rod 5, the synchronous rod 6 and the threaded rod 7, the height of the second roller 10 can be adjusted according to the specifications of the wire harness, so as to adapt to different specifications of wire harnesses.

[0038] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
