[0023] Please refer to Figures 1-5 , the present utility model provides a technical solution: a new type of cable sheath protector, including a box body 1, a wiring hole 2, a mounting plate 3, a fixed plate 4, a cable sheath protector 5 and a moving device 6. A plurality of groups of wiring holes 2 are opened on the surface of the box body 1. The mounting plate 3 is fixedly connected to the surface of the box body 1. The fixed plate 4 is arranged inside the box body 1. The cable sheath protector 5 is fixedly connected to the surface of the fixed plate 4. The moving device 6 is arranged on the surface of the box body 1.
[0024] Next, specifically describe the specific settings and functions of its moving device 6 and dust-proof device 7.
[0025] In this embodiment: The moving device 6 includes a rotating shaft 601. One end of the rotating shaft 601 is rotatably connected to the inner wall of the box body 1. The other end of the rotating shaft 601 penetrates the surface of the box body 1 and is fixedly connected with a rotating valve 602. The surface of the rotating shaft 601 is fixedly connected with a driving gear 603.
[0026] The effects achieved by the above components are: Rotating the rotating valve 602 causes the rotating shaft 601 to rotate, thereby driving the driving gear 603 to rotate.
[0027] Specifically, the number of driving gears 603 is two groups and they are symmetrically arranged. The surfaces of the driving gears 603 are both meshed with driven gears 604. The surface of the driven gear 604 is fixedly connected with a cylinder 605. The surface of the cylinder 605 is rotatably connected with a connecting rod 606. The other end of the connecting rod 606 is rotatably connected with a connecting column 607. One ends of the cylinder 605 and the connecting column 607 are both fixedly connected with anti-disengagement disks 608.
[0028] The effects achieved by the above components are as follows: The driving gear 603 drives the driven gear 604 to rotate, causing the cylinder 605 to rotate accordingly, and further causing the connecting rod 606 to push the connecting column 607. The anti - detachment disk 608 is provided to prevent the connecting rod 606 from detaching from the cylinder 605 and the connecting column 607.
[0029] Specifically, the other end of the connecting column 607 is fixedly connected with a connecting plate 609. The connecting plate 609 is fixedly connected to the surface of the fixed plate 4. A slider 610 is fixedly connected to the surface of the connecting plate 609. An anti - detachment block 611 is fixedly connected to the surface of the slider 610. A sliding groove 612 is formed in the inner wall of the box body 1. The slider 610 is slidably connected to the surface of the sliding groove 612. An anti - detachment groove 613 is formed in the inner wall of the box body 1. The anti - detachment block 611 is slidably connected to the surface of the anti - detachment groove 613.
[0030] The effects achieved by the above components are as follows: When the cylinder 605 is in its initial state, it is far from the fixed plate 4. When the cylinder 605 rotates half a turn, the connecting rod 606 pushes the connecting column 607 and the connecting plate 609, causing the slider 610 to slide out of the box body 1 along the sliding groove 612. At the same time, the anti - detachment block 611 slides in the anti - detachment groove 613, causing part of the cable sheath protector 5 to be exposed outside the box body 1, which is convenient for maintenance and inspection. The anti - detachment block 611 and the anti - detachment groove 613 are provided to prevent the slider 610, the connecting plate 609, and the fixed plate 4 from detaching from the box body 1.
[0031] Specifically, a ratchet wheel 614 is fixedly connected to the surface of the rotating shaft 601 outside the box body 1. A fixed platform 615 is fixedly connected to the surface of the box body 1. A central column 616 is fixedly connected to the surface of the fixed platform 615. The other end of the central column 616 is fixedly connected to the surface of the box body 1. A pawl 617 is rotatably connected to the surface of the central column 616. The pawl 617 is snap - connected to the surface of the ratchet wheel 614. A first spring 618 is fixedly connected to the surface of the fixed platform 615. The other end of the first spring 618 is fixedly connected to the pawl 617.
[0032] The effects achieved by the above components are as follows: The pawl 617 catches the ratchet wheel 614, making the rotating shaft 601 unable to rotate, so that the cable sheath protector 5 remains fixed during daily use. When it is necessary to move the cable sheath protector 5 outward, lift the pawl 617, causing the pawl 617 to rotate upward along the central column 616, and at the same time stretching the first spring 618, so that the pawl 617 disengages from the ratchet wheel 614. After losing the restriction, the rotating shaft 601 can rotate. After moving the cable sheath protector 5 to the outermost side, lower the pawl 617 so that it catches the ratchet wheel 614 again to prevent displacement during maintenance and inspection.
[0033] Specifically, a dust-proof device 7 is provided on the surface of the box body 1. The dust-proof device 7 includes a connecting platform 71 which is fixedly connected to the surface of the box body 1. A plurality of connecting holes 72 are formed on the surface of the connecting platform 71, and the positions of the connecting holes 72 correspond to those of the wiring holes 2.
[0034] The effect achieved by the above components is that the connecting platform 71 is provided to enable the circuit to pass through the connecting holes 72 before passing through the wiring holes 2, which is convenient for installing the dust-proof device 7.
[0035] Specifically, rectangular grooves 73 are formed on the surfaces of the connecting holes 72. A second spring 74 is fixedly connected to the surface of the rectangular groove 73, and the other end of the second spring 74 is fixedly connected to a sleeve 75.
[0036] The effect achieved by the above components is that when the circuit passes through the connecting hole 72, it first contacts the sleeve 75. The outer shape of the sleeve 75 is set as a semi-trumpet shape. When the circuit moves upward, it squeezes the sleeve 75 to move to both sides respectively, causing the sleeve 75 to compress the second spring 74.
[0037] Specifically, small sealing rings 76 are fixedly connected to one ends of the connecting holes 72 close to the box body 1, and large sealing rings 77 are fixedly connected to the other ends of the connecting holes 72 far from the box body 1.
[0038] The effect achieved by the above components is that while the sleeve 75 compresses the second spring 74, it also presses the large sealing ring 77, making the sleeve 75 closely attached to the large sealing ring 77 for the first layer of dust prevention. When the circuit passes through the sleeve 75, it just corresponds to the opening position of the small sealing ring 76 and can directly pass through the wiring hole 2 closely attached to the small sealing ring 76 for the second layer of dust prevention.
[0039] Working principle: By setting the moving device 6, when the cable sheath protector 5 needs to be repaired or inspected, it is only necessary to lift the ratchet 617 first, so that the ratchet 617 rotates along the central column 616 and stretches the first spring 618, thereby making the ratchet 617 disengage from the ratchet 614, and after the restriction is released, the rotating valve 602 is rotated to rotate the rotating shaft 601, thereby making the driving gear 603 drive the driven gear 604 to rotate, and the cylinder 605 on the driven gear 604 rotates accordingly, so that the connecting rod 606 Push the connecting plate 609, so that the slider 610 slides outward along the slide groove 612, and the cable sheath protector 5 slides out of the box body 1, and then the ratchet 617 is lowered to make it clamp the ratchet 614 again, which is convenient for repairing or inspecting the cable sheath protector 5. After the operation is completed, the ratchet 617 is raised again and the rotary valve 602 is turned to slide the cable sheath protector 5 into the box body 1, and finally the ratchet 617 is lowered to fix it. By setting the moving device 6, the cable sheath protector 5 can be temporarily moved out of the box body 1 and The utility model discloses that the utility model discloses a kind of utility model, and the utility model discloses a utility model, and the utility model discloses a utility model.
