Description

Technical Field

[0001] The present invention relates to the technical field of protective devices, in particular to an inlet and outlet protection structure for a power distribution cabinet. Background Art

[0002] The inlet and outlet protection structure of the distribution cabinet usually refers to a design or device used to protect the inlet and outlet parts of the distribution cabinet. Since the inlet and outlet positions of the distribution cabinet are prone to wire entanglement, and when the length of the wire is not reserved at the inlet and outlet positions, the wire is slightly stretched from the outside, causing the connection end of the wire inside the distribution cabinet to fall off. Therefore, special protective covers or partitions are set at the inlet and outlet parts of the distribution cabinet to play a role in safety protection and anti-pulling, to prevent people from accidentally touching and causing electric shock.

[0003] In the existing patent literature, there is a patent with publication number CN 214798745 U and the name of “A protection structure for incoming and outgoing lines of a distribution cabinet”. This patent mainly pushes the wires through an elastic push head to increase the length of the wires reserved inside the push head, thereby preventing the wires from being slightly pulled; however, when the wires are excessively pulled, the tension of the wires will compress the push head. As the push head is completely compressed, the length of the wires reserved inside the push head has been used up. In this case, if the wires continue to be pulled, the connection end of the wires and the distribution cabinet will still fall off, resulting in the inability to completely avoid the risk of the connection end of the wires and the distribution cabinet falling off. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a distribution cabinet inlet and outlet wire protection structure. When the wires are stretched, two elastic wire pushing mechanisms will be compressed under the action of the wire tension. Before the elastic wire pushing mechanisms are not completely compressed, the two wire locking mechanisms will be driven to move closer to the location of the wires. Then, the two wire locking mechanisms can pass through the elastic wire bundling mechanism to clamp the wires, thereby locking the wires and preventing the wires from being continuously affected by the tensile force and causing the connection with the distribution cabinet to be interrupted, thereby better protecting the wires.

[0005] To solve the above technical problems, the technical solution of the present invention is achieved as follows:

[0006] A power distribution cabinet inlet and outlet line protection structure, comprising a protection shell, the left and right ends of the protection shell are respectively fixed with wire tubes, the front side of the protection shell is detachably fixed with a side cover, and two sets of anti-pull type cable harness components with completely opposite setting directions are installed inside the protection shell;

[0007] The anti-pull type wire harness assembly includes an elastic wire pushing mechanism, an elastic wire harness mechanism and a wire locking mechanism. The elastic wire pushing mechanism is located on the left and right sides of the protective housing and close to where the wire tube is located. The elastic wire harness mechanism and the wire locking mechanism are both located in the middle position of the protective housing. The wire locking mechanism is fixed on the elastic wire pushing mechanism and moves synchronously with the elastic wire pushing mechanism.

[0008] The elastic wire pushing mechanism comprises a pushing seat, the inner part of which is rotatably connected to a wire pushing roller, the pushing seat is fixedly connected to two guide rods penetrating outside the protective shell, and the guide rods are sleeved with a spring for pushing the pushing seat to move;

[0009] The elastic cable tie mechanism includes a cable tie frame, on which cable tie frames are rotatably connected cable tie rollers distributed in a linear array, one end of the cable tie frame away from the push seat is slidably connected to a second guide rod fixed inside the protective shell, and a second spring for pushing the cable tie frame to move is sleeved on the second guide rod, and an avoidance opening located on the cable tie frame is opened between each two adjacent cable tie rollers;

[0010] The thread locking mechanism comprises an L-shaped thread locking line, which is fixedly connected to the push seat, and a thread locking head penetrating the avoidance opening is fixed at one end of the L-shaped thread locking line away from the push seat;

[0011] The inlet and outlet line protection structure of the distribution cabinet is applied to the distribution cabinet. The linear array of the inlet and outlet line protection structure of the distribution cabinet is distributed and fixed at the bottom of one side of the distribution cabinet. The wires used to supply power to the distribution cabinet pass through the wire tube, the elastic wire pushing mechanism, two elastic wire bundling mechanisms, the elastic wire pushing mechanism and the wire tube in sequence, and then the wires are connected to various control switches in the distribution box.

[0012] This solution is adopted to restrain the wires by arranging two sets of anti-pull type wire harness components, and the two elastic wire pushing mechanisms push the wires in the upward and downward directions respectively, thereby increasing the reserved length of the wires in the protective shell. When the wires are stretched from outside the protective shell, the two elastic wire pushing mechanisms will be compressed under the action of the wire tension. Before the elastic wire pushing mechanisms are not completely compressed, the two wire locking mechanisms will be driven to move closer to the wires. Then, the two wire locking mechanisms can pass through the elastic wire harness mechanism to clamp the wires, thereby locking the wires and preventing the wires from being continuously affected by the tensile force and causing the connection with the distribution cabinet to be interrupted, thereby better protecting the wires.

[0013] As a preferred implementation of the inlet and outlet protection structure of a power distribution cabinet, an annular wire harness groove 1 is provided on the wire pushing roller, and the cross-section of the annular wire harness groove 1 is a triangular groove.

[0014] With this solution, in order to better restrain the wires, when the wire pushing roller pushes the wires, the wires will be confined in the annular wire harness groove 1, thereby reducing the risk of the wires falling off the wire pushing roller.

[0015] As a preferred implementation of the inlet and outlet protection structure of a power distribution cabinet, a pull handle is fixedly connected to one end of a guide rod away from a push seat, and the pull handle is located outside the protective shell.

[0016] By adopting this solution, in order to facilitate the installation of the wire on the wire pushing roller, the handle 1 can be pulled outward, and the push seat will compress the spring 1, so that the wire can be installed in the annular wire groove 1 of the wire pushing roller.

[0017] As a preferred implementation of the inlet and outlet protection structure of a power distribution cabinet, a second annular wire harness groove is provided on the wire harness roller, and the cross-section of the second annular wire harness groove is a triangular groove.

[0018] By adopting this solution, in order to better restrain the wires, when the wire bundling roller presses the wires, the wires will be confined in the second annular wire bundling groove, thereby reducing the risk of the wires falling off the wire bundling roller; because the two elastic wire bundling mechanisms are located between the two elastic wire pushing mechanisms, the wires are constrained by the two elastic wire bundling mechanisms, thereby guiding the wires to be pushed between the two elastic wire pushing mechanisms, thereby improving the stability and reliability of the wires on the elastic wire pushing mechanisms.

[0019] As a preferred implementation of the inlet and outlet protection structure of a distribution cabinet, a connecting rod is fixedly connected to the cable tie rack and extends to the outside of the protective shell. A pull handle is fixedly connected to one end of the connecting rod away from the cable tie rack, and the pull handle is located outside the protective shell.

[0020] With this solution, in order to facilitate the installation of the wires on the cable roller, the second handle can be pulled outward, and the push seat will compress the second spring to facilitate the installation of the wires in the second annular cable groove of the cable roller.

[0021] As a preferred implementation of the inlet and outlet protection structure of a distribution cabinet, a wire locking groove is provided at the end of the wire locking head, and the cross-section of the wire locking groove is a triangular groove; wherein the surface of the wire locking groove is provided with uneven anti-slip patterns.

[0022] This solution is adopted to improve the clamping and fixing effect of the wire locking head on the wire. A wire locking groove is provided to tighten the wire through the wire locking groove, and the anti-slip pattern can further improve the stability after clamping.

[0023] As a preferred implementation of the inlet and outlet cable protection structure of a distribution cabinet, a linear cable trough is provided at one end of the L-shaped lock line close to the push seat, and an inlet is provided on one side of the linear cable trough. A cable switch is connected to the inlet through a rotating shaft; the cable switch can only rotate in one direction with the rotating shaft as the center, and a damper is provided at the connection between the cable switch and the rotating shaft.

[0024] By adopting this scheme, in order to further restrain the wires, the wires can be placed in the linear wire trough after passing through the wire inlet, and then the wires can be installed on the wire pushing roller. Finally, the wire inlet can be closed through the wire harness switch. This can ensure that the wires will not fall off the wire pushing roller, thereby ensuring the reliability of the wire pushing roller.

[0025] After adopting the above technical solution, the beneficial effects of the present invention are:

[0026] 1. Two sets of anti-pull cable assemblies are provided to restrain the wires. Two elastic wire pushing mechanisms push the wires in the upward and downward directions respectively, thereby increasing the reserved length of the wires in the protective shell. When the wires are stretched from outside the protective shell, the two elastic wire pushing mechanisms will be compressed under the action of the wire tension. Before the elastic wire pushing mechanisms are not completely compressed, the two wire locking mechanisms will be driven to move closer to the location of the wires. Then, the two wire locking mechanisms can pass through the elastic cable binding mechanism to clamp the wires, thereby locking the wires and preventing the wires from being continuously affected by the tensile force and causing the connection with the distribution cabinet to be interrupted, thereby better protecting the wires.

[0027] 2. In order to better restrain the wires, when the wire pushing roller pushes the wires, the wires will be confined in the annular wire groove 1, thereby reducing the risk of the wires falling off the wire pushing roller; in order to better restrain the wires, when the wire bundling roller presses the wires, the wires will be confined in the annular wire bundling groove 2, thereby reducing the risk of the wires falling off the wire bundling roller; since the two elastic wire bundling mechanisms are located between the two elastic wire pushing mechanisms, the wires are constrained by the two elastic wire bundling mechanisms, thereby guiding the wires to be pushed between the two elastic wire pushing mechanisms, so as to improve the stability and reliability of the wires on the elastic wire pushing mechanisms.

[0028] 3. In order to improve the clamping and fixing effect of the wire locking head on the wire, a wire locking groove is set to tighten the wire through the wire locking groove, and the anti-slip pattern can further improve the stability after clamping.

[0029] 4. In order to further restrain the wires, the wires can be placed in the linear cable trough after passing through the cable inlet, and then the wires can be installed on the wire pushing roller. Finally, the cable inlet can be closed through the cable switch. This can ensure that the wires will not fall off the wire pushing roller, thereby ensuring the reliability of the wire pushing roller.

[0046] The anti-pull type wire harness assembly includes an elastic wire pushing mechanism 4, an elastic wire harness mechanism 5 and a wire locking mechanism 6. The elastic wire pushing mechanism 4 is located on the left and right sides of the protective housing 1 and close to the location of the wire tube 2.

The wire locking mechanism 6 is fixed on the elastic wire pushing mechanism 4 and moves synchronously with the elastic wire pushing mechanism 4.

[0047] The elastic wire pushing mechanism 4 includes a pushing seat 401, the pushing seat 401 is internally rotatably connected with a wire pushing roller 402, the pushing seat 401 is fixedly connected with two guide rods 403 penetrating to the outside of the protective shell 1, and the guide rods 403 are sleeved with a spring 404 for pushing the pushing seat 401 to move;

[0049] The thread locking mechanism 6 includes an L-shaped thread locking line 601, which is fixedly connected to the push seat 401, and a thread locking head 602 that penetrates the avoidance opening 505 is fixed at one end of the L-shaped thread locking line 601 away from the push seat 401;

[0050] The inlet and outlet line protection structure of the distribution cabinet is applied to the distribution cabinet 7. The linear array of the inlet and outlet line protection structure of the distribution cabinet is distributed and fixed at the bottom of one side of the distribution cabinet 7. The wires 8 used to supply power to the distribution cabinet 7 pass through the wire tube 2, the elastic wire pushing mechanism 4, two elastic wire bundling mechanisms 5, the elastic wire pushing mechanism 4 and the wire tube 2 in sequence, and then the wires 8 are connected to various control switches in the distribution box.

[0051] The wires 8 are constrained by providing two sets of anti-pull wire harness components, and the two elastic wire pushing mechanisms 4 push the wires in the upward and downward directions respectively, thereby increasing the reserved length of the wires 8 in the protective shell 1. When the wires 8 are stretched from outside the protective shell 1, the two elastic wire pushing mechanisms 4 will be compressed under the action of the tension of the wires 8. Before the elastic wire pushing mechanisms 4 are not completely compressed, the two wire locking mechanisms 6 will be driven to move closer to the location of the wires 8. Then, the two wire locking mechanisms 6 can pass through the elastic wire harness mechanism 5 to clamp the wires 8, thereby locking the wires 8 and preventing the wires 8 from being continuously affected by the tensile force and causing the connection with the distribution cabinet 7 to be interrupted, thereby better protecting the wires 8.

[0052] like Figures 7 and 8 As shown, the wire pushing roller 402 is provided with an annular wire beam groove 405, and the cross section of the annular wire beam groove 405 is a triangular groove.

[0053] In order to better restrain the wire 8 , when the wire pushing roller 402 pushes the wire 8 , the wire 8 will be confined in the annular wire harness groove 1 405 , thereby reducing the risk of the wire 8 falling off the wire pushing roller 402 .

[0054] like Figures 7 and 8 As shown, one end of the guide rod 403 away from the push seat 401 is fixedly connected to a pull handle 406 , and the pull handle 406 is located outside the protective shell 1 .

[0055] In order to facilitate the installation of the wire 8 on the wire pushing roller 402, the handle 406 can be pulled outward, and the push seat 401 will compress the spring 404 to facilitate the installation of the wire 8 in the annular wire groove 405 of the wire pushing roller 402.

[0056] like Figures 9 and 10 As shown, the cable tie roller 502 is provided with a second annular cable tie groove 506 , and the cross section of the second annular cable tie groove 506 is a triangular groove.

[0057] In order to better restrain the wire 8, when the wire bundling roller 502 presses the wire 8, the wire 8 will be confined in the annular wire bundling groove 2 506, thereby reducing the risk of the wire 8 falling off the wire bundling roller 502; because the two elastic wire bundling mechanisms 5 are located between the two elastic wire pushing mechanisms 4, the wire 8 is constrained by the two elastic wire bundling mechanisms 5, so as to guide the wire 8 to be pushed between the two elastic wire pushing mechanisms 4, so as to improve the stability and reliability of the wire 8 on the elastic wire pushing mechanisms 4.

[0058] like Figures 9 and 10 As shown, a connecting rod 507 penetrating to the outside of the protective shell 1 is fixedly connected to the cable tie rack 501 , and a second pull handle 508 is fixedly connected to one end of the connecting rod 507 away from the cable tie rack 501 . The second pull handle 508 is located outside the protective shell 1 .

[0059] In order to facilitate the installation of the wire 8 on the wire bundling roller 502 , the second pull handle 508 can be pulled outward, and the push seat 401 will compress the second spring 504 to facilitate the installation of the wire 8 in the second annular wire bundling groove 506 of the wire bundling roller 502 .

[0060] like Figure 11 to Figure 12 As shown, a thread locking groove 603 is provided at the end of the thread locking head 602, and the cross section of the thread locking groove 603 is a triangular groove; wherein, the surface of the thread locking groove 603 is provided with uneven anti-slip patterns.

[0061] In order to improve the clamping and fixing effect of the wire locking head 602 on the wire 8, a wire locking groove 603 is provided, and the wire 8 is tightened by the wire locking groove 603, and the anti-slip pattern can further improve the stability after clamping.

[0062] like Figure 11 to Figure 12 As shown, a linear cable groove 604 is provided at one end of the L-shaped lock line 601 close to the push seat 401, and a cable inlet 605 is provided on one side of the linear cable groove 604. A cable switch 607 is rotatably connected to the cable inlet 605 via a rotating shaft 606; wherein the cable switch 607 can only rotate in one direction around the rotating shaft 606, and a damper is provided at the connection between the cable switch 607 and the rotating shaft 606.

[0063] In order to further restrain the wire 8, the wire 8 can be placed in the linear wire groove 604 after passing through the wire inlet 605, and then the wire 8 can be installed on the wire pushing roller 402. Finally, the wire inlet 605 can be closed through the wire binding switch 607. This can ensure that the wire 8 will not fall off the wire pushing roller 402, thereby ensuring the reliability of the wire pushing roller 402.

[0064] Working principle of the present invention:

[0065] When in use, the linear array of the inlet and outlet line protection structure of the distribution cabinet is distributed and fixed at the bottom of one side of the distribution cabinet 7. The wires 8 used to supply power to the distribution cabinet 7 pass through the wire tube 2, the elastic wire pushing mechanism 4, two elastic wire bundling mechanisms 5, the elastic wire pushing mechanism 4 and the wire tube 2 in sequence, and then the wires 8 are connected to various control switches in the distribution box.

[0066] Since the two elastic wire pushing mechanisms 4 push the wire 8 in the upward and downward directions respectively, the reserved length of the wire 8 in the protective shell 1 can be increased. When the wire 8 is stretched from outside the protective shell 1, the two elastic wire pushing mechanisms 4 will be compressed under the action of the tension of the wire 8. Before the elastic wire pushing mechanism 4 is not completely compressed, the two wire locking mechanisms 6 will be driven to move closer to the location of the wire 8. Then, the two wire locking mechanisms 6 can pass through the elastic wire bundling mechanism 5 to clamp the wire 8, thereby locking the wire 8 and preventing the wire 8 from being continuously affected by the tensile force and causing the connection with the distribution cabinet 7 to be interrupted, thereby better protecting the wire 8.

[0067] Among them, when the wire 8 passes through the elastic wire pushing mechanism 4, the wire 8 should be installed in the annular wire groove 405 of the wire pushing roller 402. When the wire pushing roller 402 pushes the wire 8, the wire 8 will be confined in the annular wire groove 405, thereby reducing the risk of the wire 8 falling off the wire pushing roller 402.

[0068] Among them, when the wire 8 passes through the elastic wire bundling mechanism 5, the wire 8 should be installed in the annular wire bundling groove 2 506 of the wire bundling roller 502. When the wire bundling roller 502 presses the wire 8, the wire 8 will be confined in the annular wire bundling groove 2 506, thereby reducing the risk of the wire 8 falling off the wire bundling roller 502; because the two elastic wire bundling mechanisms 5 are located between the two elastic wire pushing mechanisms 4, the wire 8 is constrained by the two elastic wire bundling mechanisms 5, so as to guide the wire 8 to be pushed between the two elastic wire pushing mechanisms 4, so as to improve the stability and reliability of the wire 8 on the elastic wire pushing mechanisms 4.

[0069] Among them, when the wire 8 passes through the wire locking mechanism 6, the wire 8 should be installed in the linear wire harness groove 604. The wire 8 can be placed in the linear wire harness groove 604 after passing through the wire inlet 605, and then the wire 8 can be installed on the wire pushing roller 402. Finally, the wire inlet 605 can be closed through the wire harness switch 607. This can ensure that the wire 8 will not fall off the wire pushing roller 402, thereby ensuring the reliability of the wire pushing roller 402.

[0070] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
