DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0029] Example 1, refer to Figures 1-5 , the first embodiment of the present application, the embodiment provides a kind of power distribution box with cable protection structure, can realize the effect of protecting cable body 3 in power distribution box housing 1, it includes power distribution box housing 1, its inside is equipped with multiple control switches 2, control switch 2 lower end is equipped with cable body 3, power distribution box housing 1 bottom is equipped with multiple openings for cable body 3 to pass through;Blocking mechanism, it is arranged in the inner wall of power distribution box housing 1, it plays a supporting role to cable body 3;Anti-loose mechanism, it is arranged in the side wall of cable body 3, it cooperates with blocking mechanism to prevent cable body 3 from loosening when pulling;Reinforcing mechanism, it is arranged in anti-loose mechanism, it is equipped with elastic friction pad 71 in arc shape, elastic friction pad 71 is extruded to further prevent cable body 3 from loosening;Adjusting mechanism, it is arranged in blocking mechanism, it adjusts blocking mechanism to adapt to different thick and thin cable body 3;Dial mechanism, it is arranged in the upper end of adjusting mechanism, it provides power for the movement of adjusting mechanism.

[0030] ​Specifically, the beam is arranged in the distribution box shell 1, and multiple control switches 2 can be fixed. The cable bodies 3 are connected between the multiple switches. Finally, several cable bodies 3 are wound from the bottom of the distribution box shell 1. The distribution box shell 1 is fixed on the wall or the formwork, so that the wires are led out from the bottom. This is the prior art, which will not be described here.

[0031] Further, the opening is provided with an elastic sealing plug 4, and the upper and lower ends of the elastic sealing plug 4 are arc-shaped. The blocking mechanism includes a ring 51 arranged in the distribution box shell 1, a plurality of mounting grooves 52 are arranged in the ring 51, and an arc-shaped block 53 is slidably connected in each of the mounting grooves 52. The ring 51 is provided with a fixing piece 54 for supporting the ring 51. The fixing piece 54 includes a connecting plate 541 fixedly connected to the ring 51, and a horizontal plate 542 fixedly connected to the connecting plate 541. The horizontal plate 542 is fixedly connected to the distribution box shell 1 by bolts 543.

[0032] Among them, the upper and lower ends of the elastic sealing plug 4 are arc-shaped, so that the cable body 3 is not easy to be stuck when threading. The mounting grooves 52 are arranged in pairs. The combination of the horizontal plate 542 and the connecting plate 541 can also be replaced by embedding the bolt 543 in the connecting plate 541, so that the connecting plate 541 is directly fixed to the inside of the distribution box shell 1. Only the connecting plate 541 needs to be fixed here, and the specific limitation is not limited.

[0033] Preferably, the anti-loose mechanism includes a mounting ring 61 arranged on the outer side of the cable body 3. The mounting ring 61 is provided with a threaded hole penetrating the mounting ring 61. A first screw 62 is threadedly connected in the threaded hole. The mounting ring 61 is provided with two accommodating grooves 63. A limiting block 64 is slidably connected in each of the accommodating grooves 63. The limiting block 64 is elastically connected to the inner wall of the accommodating groove 63 by a first spring 65. The limiting block 64 is provided with an inclined surface 66. The outer end of the first screw 62 does not extend to the outer side of the mounting ring 61. The first screw 62 is provided with a cross-shaped groove. A rubber pad 67 abutting against the cable body 3 is rotatably connected to the first screw 62.

[0034] It should be noted that the first screw 62 rotates in the threaded hole, so that the first screw 62 can move towards the cable body 3, drive the rubber pad 67 to abut against the cable body 3, and fix the mounting ring 61 and the cable body 3. The friction coefficient of the surface of the rubber pad 67 abutting against the cable body 3 is high, which prevents the cable body 3 from loosening. The outer end of the first screw 62 does not extend to the outer side of the mounting ring 61, which avoids the first screw 62 from being moved and the rubber pad 67 from loosening.

[0035] In use, when the cable body 3 is connected with the control switch 2, first, the position of the mounting ring 61 is determined according to the need, it is worth noting that when the position of the mounting ring 61 is determined, the upper end of the cable body 3 is first placed at the position of the control switch 2, then the position of the mounting ring 61 is determined according to the position of the circular ring 51, but some allowance needs to be left to ensure that the cable body 3 has a bending space after being connected to cope with thermal expansion and contraction, then the mounting ring 61 is put on the cable body 3 and slid to the specified position, then the first screw rod 62 is rotated to make the first screw rod 62 move towards the cable body 3, so that the rubber pad 67 is tightly pressed against the side wall of the cable body 3, realizing the fixation between the mounting ring 61 and the cable body 3, then the cable body 3 and the mounting ring 61 pass through the circular ring 51, when the mounting ring 61 passes through the circular ring 51, the inclined surface 66 of the limiting block 64 on the mounting ring 61 first abuts against the bottom of the arc-shaped block 53, so that the limiting block 64 moves towards the accommodating groove 63, and the first spring 65 is compressed, when the limiting block 64 passes over the arc-shaped block 53, under the action of the first spring 65, the limiting block 64 is pushed out of the accommodating groove 63, at this time, the bottom of the limiting block 64 abuts against the upper end of the arc-shaped block 53, at this time, the limiting block 64 cannot move downward, the mounting ring 61 cannot move downward, and thus the cable body 3 cannot move downward, ensuring the stability between the cable body 3 and the control switch 2, even if the cable body 3 is pulled, it will not affect the stability between the cable body 3 and the control switch 2.

[0036] In summary, by setting the blocking mechanism and the anti-loose mechanism, when the lower end surface of the limiting block 64 on the mounting ring 61 abuts against the upper end surface of the arc-shaped block 53 on the circular ring 51, even if the cable body 3 outside the distribution box shell 1 is pulled, the loosening between the cable body 3 and the control switch 2 can be avoided, and the protection of the cable body 3 is realized.

[0037] Embodiment 2, refer to Figures 1-5For the second embodiment of the present application, unlike the previous embodiment, the embodiment provides a reinforcing mechanism of the distribution box with the cable protection structure, solves the problem of how to avoid loosening between the mounting ring 61 and the cable body 3, which comprises a mounting port 72 arranged at the lower end of the limiting block 64, a top plate 73 slidably connected in the mounting port 72 and matched with the arc-shaped plate, an L-shaped slot 74 penetrating through the limiting block 64 at the upper end of the limiting block 64, a connecting slot extending into the mounting port 72 arranged on the L-shaped slot 74, an L-shaped plate 75 slidably connected in the L-shaped slot 74, a resisting block 76 penetrating through the connecting slot and fixedly connected to the L-shaped plate 75, the resisting block 76 being fixedly connected to the top plate 73, the L-shaped plate 75 being elastically connected to the inner wall of the L-shaped slot 74 through a second spring 77, the upper end of the mounting ring 61 being provided with an L-shaped supporting slot 78, the lower end of the supporting slot 78 extending into the accommodating slot 63, a first arc-shaped slot matched with the elastic friction pad 71 being arranged in the inner end of the supporting slot 78, a push plate 79 being slidably connected in the supporting slot 78, the push plate 79 being fixedly connected to the elastic friction pad 71, and a notch matched with the L-shaped plate 75 being arranged on the push plate 79.

[0038] Specifically, in the embodiment 1, the mounting port 72 is not arranged, so that the bottom of the limiting block 64 is in contact with the arc-shaped plate. In the present embodiment, the lower end surface of the top plate 73 is in abutment with the upper end surface of the arc-shaped block 53. The arrangement of the elastic friction pad 71 enables the push plate 79 to be pushed. When the push plate 79 is pushed, the elastic friction pad 71 is subjected to extrusion force, thereby preventing the cable body 3 from loosening.

[0039] In use, when the cable body 3 is installed, the lower end surface of the top plate 73 is in abutment with the upper end surface of the arc-shaped block 53. When the lower end of the cable body 3 is pulled, the top plate 73 is in abutment with the arc-shaped block 53. Since the arc-shaped block 53 cannot move up and down (because the horizontal plate 542 is fixed in height, thereby the connecting plate 541 is fixed in height, so that the arc-shaped plate is fixed in height and cannot move up and down), the top plate 73 moves upward. At this time, according to the relative motion, the limiting block 64 moves downward, so that the cable body 3 is slightly pulled. As mentioned in the embodiment 1, a surplus amount is left. At this time, the stability of the connection between the cable body 3 and the control switch 2 is not affected. When the top plate 73 moves, the resisting block 76 is pushed to move upward, the L-shaped plate 75 moves upward, and the second spring 77 is compressed. When the L-shaped plate 75 moves upward, the push plate 79 is pushed to move toward the elastic friction pad 71, so that the elastic friction pad 71 is further extruded. The extrusion force increases, the normal force increases, the friction force increases, the stability between the mounting ring 61 and the cable body 3 is ensured, and the sliding of the cable body 3 is avoided.

[0040] It is worth noting that when the lower end of the cable body 3 is pulled, the limiting block 64 moves a small distance (relative motion), which can provide a small amount of buffering, thereby avoiding the sharp pressure between the limiting block 64 and the arc-shaped block 53, and causing the loosening of the arc-shaped block 53.

[0041] In summary, by setting the reinforcing mechanism, when the lower end of the cable body 3 is pulled, the L-shaped plate 75 is also driven to push the push plate 79, so that the pressure on the elastic friction pad 71 increases, the friction force increases, and the relative movement between the cable body 3 and the mounting ring 61 is further avoided, so that the connection between the cable body 3 and the control switch 2 is more stable.

[0042] Embodiment 3, refer to Figures 1-6 Figures 1-6 , the third embodiment of the present application, different from the previous embodiment, this embodiment provides an adjusting mechanism for the distribution box with cable protection structure, solves the problem of how to adjust the position of the arc-shaped block 53, and applies to different thick and thin cable bodies 3, which comprises an annular groove 81 provided on the circular ring 51, the annular groove 81 is communicated with the mounting groove 52, the guide ring 82 is rotatably connected in the annular groove 81, a plurality of second arc-shaped grooves 83 are arranged on the guide ring 82, a guide column 84 matched with the second arc-shaped groove 83 is arranged on the limiting block 64, the number of the second arc-shaped grooves 83 is equal to the number of the arc-shaped blocks 53, and the distance between the second arc-shaped grooves 83 and the inner wall of the circular ring 51 decreases in turn along the clockwise direction of the guide ring 82; the dialing mechanism comprises an arc-shaped port 91 provided on the circular ring 51, a second screw 92 is arranged in the arc-shaped port 91, a threaded port matched with the second screw 92 is arranged on the guide ring 82, a cap 93 is fixedly connected to the second screw 92, and an anti-skid pad 94 is fixedly connected to the cap 93.

[0043] Specifically, the distance between the second arc-shaped groove 83 and the inner wall of the circular ring 51 decreases in turn along the clockwise direction (the same below, observing from the direction of the circular ring 51) of the guide ring 82, when the guide ring 82 rotates counterclockwise, the guide column 84 moves towards the inner circle of the circular ring 51, the setting of the anti-skid pad 94 avoids the self-moving of the cap 93, avoids the self-moving of the cap 93, and ensures that the arc-shaped block 53 does not self-slide.

[0044] In use, when it is necessary to protect a larger diameter cable body 3, the diameter of the mounting ring 61 increases, the position of the limiting block 64 corresponds to the larger diameter, so that the position of the arc-shaped block 53 needs to be adjusted, at this time, only need to rotate the cap 93, so that the second screw 92 rotates, the second screw 92 moves outward, the anti-skid pad 94 is separated from the upper end surface of the circular ring 51, at this time, the cap 93 is rotated clockwise, so that the second screw 92 rotates clockwise, so that the second arc-shaped groove 83 cooperates with the guide rod to drive the guide rod to move away from the inner circle of the circular ring 51, so that the arc-shaped block 53 moves towards the inside of the mounting groove 52, thereby adjusting the position of the arc-shaped block 53 to adapt to the larger diameter mounting ring 61.

[0045] In summary, by setting the adjusting mechanism and the dialing mechanism, when the larger cable body 3 needs to be protected and the arc-shaped block 53 needs to be adjusted, the second screw 92 is only needed to be dialed to make the guide ring 82 rotate clockwise, so that the arc-shaped block 53 moves into the installation groove 52 to adapt to the larger diameter installation ring 61. When the smaller diameter installation ring 61 needs to be adapted, the guide ring 82 is reversed to be dialed.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the present application, and they should be covered in the scope of the claims of the present application.
