Each limiting seat has a cable harness seat movably connected to its back side via a movable component.

[0005] The limiting seat has a guide groove at one end away from the adjacent wire harness seat. The inner sidewall of the guide groove has a sliding groove. A limiting roller is provided in the guide groove. The two ends of the limiting roller shaft are respectively engaged with the interior of the adjacent sliding groove by fixed sliders. The top ends of the two sliders are respectively connected to the inner top wall of the sliding groove by tension springs. The limiting roller is limited by an inserted stop rod. A baffle for contacting the switch is fixed at one end of the limiting seat away from the adjacent wire harness seat.

[0006] The bottom of the cable harness is provided with an arc-shaped groove that fits the bearing ring;

[0007] The front of the limiting seat is provided with a cable harness groove I for limiting the cable, and the inside of the cable harness is provided with a cable harness groove II corresponding to the cable harness groove I.

[0008] Furthermore, the movable component includes a T-shaped connecting plate fixed to the cable harness seat, and a connecting slot adapted to the connecting plate is provided at the limiting seat.

[0009] Furthermore, the stop bar is inclined downwards, and the bottom of the stop bar contacts the outer ring of the limiting roller.

[0010] Furthermore, a rubber ring is fixedly sleeved on the outer ring of the limiting roller.

[0011] Furthermore, the initial position of the limiting roller is exposed at the bottom of the limiting seat.

[0012] Furthermore, a rubber pad is fixed to the center of the bearing ring.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] After installation, this mounting structure allows for easy disassembly and maintenance without the need for additional tools. Furthermore, the angle of the switch can be adjusted during installation via the rotating bearing ring, and the cable management system, including cable management slots I and II, enables efficient cable management.

[0020] To facilitate understanding of this utility model, the device of this utility model will be described more fully below with reference to the accompanying drawings. Embodiments of the device are shown in the drawings. However, this device can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example

[0023] like Figure 1-4As shown, this embodiment provides a switching switch installation structure in a distribution box, including a bearing ring 1 fixed to the inner wall of the distribution box and two limiting seats 3 symmetrically arranged at the bearing ring 1 (four limiting seats 3 can be set as needed to achieve a better limiting effect). The back of each limiting seat 3 is movably connected to a cable tray 4 through a movable component. The movable component includes a T-shaped connecting plate 5 fixed at the cable tray 4. A connecting slot 16 adapted to the connecting plate 5 is opened at the limiting seat 3. Through the movable connection, the cable tray 4 can be removed when the internal space of the distribution box is small and it is inconvenient to install it.

[0024] The limiting seat 3 has a guide groove 6 at one end away from the adjacent cable tray 4. The inner side wall of the guide groove 6 has a sliding groove 7. The limiting roller 9 is provided in the guide groove 6, and the outer ring of the limiting roller 9 is fixedly fitted with a rubber ring to prevent wear on the switch. The two ends of the rotating shaft of the limiting roller 9 are respectively engaged with the adjacent sliding groove 7 by fixed sliders. The top ends of the two sliders are respectively connected to the inner top wall of the sliding groove 7 by tension springs 8. The initial position of the limiting roller 9 is exposed at the bottom of the limiting seat 3, so that when the switch is inserted and installed, it can contact the limiting roller 9 and push it up to pass through. Then, the rebound of the tension spring 8 makes the limiting roller 9 reset, thus completing the limiting work of the switch.

[0025] The limiting roller 9 is limited by the inserted stop rod 11. The end of the limiting seat 3 away from the adjacent wire harness seat 4 is fixed with a baffle 12 for contacting the switch. Specifically, the stop rod 11 is inclined downward. The inner wall of the guide groove 6 is provided with an inclined groove 10 that matches the stop rod 11. The stop rod 11 is inserted into the inclined groove 10 through the through opening on the front of the limiting seat 3 until it is inserted into the inclined groove 10, so as to achieve vertical limiting. The bottom of the stop rod 11 contacts the outer ring of the limiting roller 9. After the stop rod 11 is inserted, the vertical position of the limiting roller 9 can be limited, that is, the limiting function of the inserted switch can be realized.

[0026] The bottom of the cable harness 4 is provided with an arc-shaped groove 14 that matches the bearing ring 1 to prevent wear with the bearing ring 1. (When the limiting seat 3 and the cable harness 4 are installed together and then installed on the bearing ring 1 as a whole, if the arc-shaped groove 14 is missing, the cable harness 4 will block the bearing ring 1. When the two are installed together as a whole on the bearing ring 1, the arc-shaped groove 14 is placed downwards corresponding to the outer ring of the bearing ring 1 so that the cable harness 4 is sleeved on the outside of the bearing ring 1. At this time, the limiting seat 3 can be fixed to the bearing ring 1.)

[0027] The front of the limiting seat 3 is provided with a cable snagging groove I13 for limiting the cable, and the inside of the cable snagging seat 4 is provided with a cable snagging groove II15 corresponding to the cable snagging groove I13 for cable snagging.

[0028] It should be noted that the bearing ring 1 includes a damping bearing installed on the inner wall of the distribution box, and a stainless steel ring for rotation fixedly sleeved inside the damping bearing. The fixing hole 2 is opened at the stainless steel ring, and the rubber pad 17 is fixed to the inner ring of the stainless steel ring, which will not affect the normal rotation of the outer ring bearing. Its function is to provide a compression function when the switch is inserted (to clamp the switch in cooperation with the limit seat 3), and at the same time, it has the effects of insulation and anti-friction.

[0029] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
