[0033] See Figure 1 as shown in
[0034] A wiring device for high-speed rail vehicles, comprising: a mounting table 1, a connecting plate 2, a U-shaped frame 3, an adjusting mechanism 4, a limiting mechanism 5, a placing pad 6, a card slot 7, a pressing plate 8;
[0035] At both ends on one side of the mounting table 1, connection grooves are provided, and the connecting plate 2 is slidably connected through the connection grooves. The two connecting plates 2 are symmetrically arranged. The ends of the two connecting plates 2 are exposed outside the mounting table 1, and U-shaped frames 3 are fixedly connected to the ends of the two connecting plates 2. The telescopic sliding of the connecting plate 2 can drive the displacement of the U-shaped frame 3. When the U-shaped frame 3 moves, the connecting plate 2 can assist in guiding and supporting the movement of the U-shaped frame 3, so that it moves stably. An adjusting mechanism 4 is arranged on the outer surface of the mounting table 1;
[0036] See Figure 2 as shown in
[0037] The adjusting mechanism 4 includes a component cavity 401;
[0038] The inner wall of the component cavity 401 is provided inside the mounting table 1. Two symmetrically arranged sliding grooves 402 are provided on the inner wall of the component cavity 401, and two through holes 403 are provided on the inner wall of the component cavity 401 corresponding to the ends of the sliding grooves 402. The component cavity 401 is slidably connected with a rack 404 through the two sliding grooves 402. The rack 404 passes through the through holes 403, and the end of the rack 404 is exposed outside the mounting table 1, and the end of the rack 404 is fixedly connected with the U-shaped frame 3. In this structure, the rack 404 slides directionally in the groove of the sliding groove 402, thereby driving the U-shaped frame 3 to move stably;
[0039] A first rotating shaft 405 is rotatably connected to the bottom wall of the component cavity 401 at the middle position between the two racks 404. A gear 406 is fixedly connected to the first rotating shaft 405. The gear 406 is synchronously engaged with the two racks 404. The top end of the first rotating shaft 405 penetrates the upper surface of the mounting table 1, and a rotating handle 408 is fixedly connected to the top end of the first rotating shaft 405. Anti-slip lines are provided on the surface of the rotating handle 408 to increase the friction force during hand rotation and avoid the phenomenon of hand slipping when rotating the rotating handle 408.
[0040] See Figure 1 and 3 as shown in
[0041] A limiting mechanism 5 is arranged on the upper surface of the mounting table 1;
[0042] The limiting mechanism 5 includes a frame 501, the bottom surface of the frame 501 is fixedly connected to the upper surface of the mounting table 1, an arc-shaped groove 502 is formed on the upper surface of the frame 501, and a guiding groove 503 is formed on the bottom surface of the frame 501.
[0043] A moving ring 504 is slidably connected to the frame 501 through the guiding groove 503. Among them, a gear 406 is fixedly connected to the first rotating shaft 405, and a chuck 407 is fixedly connected to the upper part of the first rotating shaft 405. Among them, the guiding groove 503 can guide the movement of the moving ring 504, so that the moving ring 504 drives the friction pad 505 to stably abut against the groove of the chuck 407, thereby limiting the chuck 407. A friction pad 505 is fixedly connected to the inner wall of the engaging end of the moving ring 504;
[0044] An arc-shaped groove 502 is formed on the upper surface of the frame 501 for slidably connecting with the third rotating shaft 508. A spring 510 for driving the moving ring 504 to disengage from the chuck 407 and a rotating structure connected to the third rotating shaft 508 are further installed inside the frame 501;
[0045] The rotating structure includes a second rotating shaft 506 and a convex block 507. The second rotating shaft 506 is rotatably connected to the frame 501, a convex block 507 is movably connected between the second rotating shaft 506 and the third rotating shaft 508, and a handle 509 is fixedly connected to the top end of the third rotating shaft 508;
[0046] During use, the third rotating shaft 508 moves along the track of the arc-shaped groove 502. When the third rotating shaft 508 moves to the A-end extreme point of the arc-shaped groove 502, at this time, the convex block 507 can push the moving ring 504 to move, so that the moving ring 504 drives the friction pad 505 to stably abut against the groove of the chuck 407, thereby limiting the chuck 407. Two springs 510 are fixedly connected to the outer surface of the moving ring 504, and the end of the spring 510 far from the outer surface of the moving ring 504 is fixedly connected to the inner wall of the frame 501. The state of the spring 510 is always in a compressed state. When the third rotating shaft 508 moves to the B-end extreme point of the arc-shaped groove 502, at this time, the spring 510 extends, pushing the moving ring 504 to move so that the friction pad 505 releases the abutment against the chuck 407, thereby automatically releasing the limit on the adjusting mechanism 4.
[0047] Placing pads 6 are fixedly connected to the inner bottom walls of both of the two U-shaped frames 3. The material of the placing pads 6 is preferably rubber material. At this time, after the cable is squeezed and fixed, its material characteristics can protect the cable and prevent the cable from being damaged due to extrusion. Card slots 7 are symmetrically formed on the two inner side walls of the two U-shaped frames 3. The pressing plates 8 are inserted and removed through the card slots 7 so that the U-shaped frames 3 form a closed annular structure, thereby fixedly connecting the cable.
[0048] In the above technical solution, a wiring device for high-speed rail vehicles provided by the present utility model;
[0049] Working principle:
[0050] When using this device, first, place the cable on the placement pad 6 inside the U-shaped frame 3, then press the pressing plate 8 against the cable, and then insert it according to the corresponding card slot 7 to squeeze and fix the cable.
[0051] Secondly, manually rotate the rotating handle 408 to drive the first rotating shaft 405 and the gear 406 to rotate. Then, the rotation of the gear 406 can drive the rack bars 404 engaged on both sides to move outward synchronously. At this time, the movement of the rack bars 404 can push the U-shaped frames 3 on both sides to move, thereby finely adjusting the fixed cable.
[0052] Finally, after the position of the cable is adjusted, hold the handle 509 to drive the third rotating shaft 508 to move along the track of the arc-shaped groove 502. While the third rotating shaft 508 is moving, the convex block 507 rotates around the second rotating shaft 506 as the center. When the third rotating shaft 508 moves to the A-end extreme point of the arc-shaped groove 502, at this time, the convex block 507 can push the moving ring 504 to squeeze the spring 510, and while the moving ring 504 is moving, it drives the friction pad 505 to squeeze the chuck 407, thereby making the first rotating shaft 405 unable to rotate, and thus making the U-shaped frame 3 unable to move;
[0053] This wiring device is simple and convenient to operate, can quickly fix the cable, and the device can be reused, effectively avoiding waste of auxiliary materials and saving production costs.
[0054] Only some exemplary embodiments of the present utility model have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
