[0033] Reference Figure 1-9 A cable protection device for wiring of an electrical cabinet provided in an embodiment of the present invention comprises a plurality of terminals 2 for being plugged into a cabinet body 1, a connecting portion 3 being provided between each of the terminals 2 and each cable; a supporting mechanism, the length of which is greater than the distance between two adjacent connecting portions 3, the supporting mechanism having a first position abutting against the connecting portion 3 for support and a second position away from the connecting portion 3; and a first power component for driving the supporting mechanism to switch between the first position and the second position.

[0034] Specifically, the electrical cabinet is usually used to store electrical equipment and control equipment to protect them from the influence of the external environment. The cable is in the shape of a wire, and the terminal 2 is the connector at both ends of the cable. The cabinet body 1 is provided with an interface adapted to the terminal 2. The signal is transmitted by plugging the terminal 2 with the interface. The connecting part 3 is arranged between the cable and the terminal 2, and the connecting part 3 is preferably made of hard plastic material. In order to prevent the terminal 2 and the connecting part 3 from being damaged, a protective shell is usually set one by one at the connecting position of the terminal 2 and the connecting part 3 to achieve the purpose of protection, thereby ensuring the normal connection of the equipment. This is a prior art and will not be repeated. One of the core innovations of the embodiment of the present invention is that a supporting mechanism is arranged below the connecting part 3.

[0035] Preferably, the supporting mechanism includes a lifting plate 4 slidably arranged on the cabinet body 1, and a plurality of vertical rods 5 are arranged on the lifting plate 4. The plurality of connecting parts 3 are respectively located on the movement range of the plurality of vertical rods 5. Specifically, a vertical groove 6 is opened on the outer wall of the cabinet body 1, and the lifting plate 4 can slide vertically along the vertical groove 6. The plurality of vertical rods 5 are arranged on the upper surface of the lifting plate 4. Through the vertical movement of the lifting plate 4, the vertical rods 5 can be driven to abut and move away from the connecting part 3, thereby facilitating the switching of the supporting mechanism between the first position and the second position.

[0036] Preferably, the first power assembly includes a cylinder 7, which is fixed to the cabinet 1, and the output end of the cylinder 7 is fixed to the lifting plate 4. By controlling the extension or contraction of the output end of the cylinder 7, the power required for the support mechanism to switch between the first position and the second position can be provided.

[0037] As another embodiment of the present invention, a self-adjusting mechanism for adaptively supporting terminals 2 of different heights is arranged between the vertical pole 5 and the cabinet body 1. Specifically, multiple vertical poles 5 are slidably arranged on the lifting plate 4. The self-adjusting mechanism can be a reciprocating drive component such as multiple electric push rods 27. The output ends of the multiple electric push rods 27 are independently connected to the multiple vertical poles 5 respectively, so as to realize independent control of the multiple vertical poles 5, thereby facilitating adaptation to terminals 2 of different heights.

[0038] As another embodiment of the present invention, the self-adjusting mechanism includes a top plate 8, a sliding seat 9 is fixedly connected to the cabinet body 1, the top plate 8 is slidably set on the sliding seat 9, a through hole 10 is opened on the top plate 8, a latch 11 is slidably set in the through hole 10, the vertical rod 5 is opened with a socket 12 adapted to the size of the latch 11, and a plurality of positioning holes 13 adapted to the size of the latch 11 are opened on the sliding seat 9, the latch 11 has a first state of being plugged into the socket 12 and a second state of being plugged into one of the positioning holes 13; and also includes a device for driving the latch 11 in the first state and the second state. The second power component for switching between states, specifically, in this embodiment, the upright rod 5 is fixedly connected to the lifting plate 4, and the connecting portion 3 is located on the movement stroke of the top plate 8, the sliding seat 9 is provided with a slide rail 14, and the top plate 8 is provided with a sliding connection portion 15, the sliding connection portion 15 is slidably connected with the slide rail 14, the through hole 10 is opened inside the top plate 8 and is arranged horizontally, the latch 11 is a cylindrical rod-shaped structure and is coaxially arranged with the through hole 10, the positioning holes 13 are evenly arranged in the vertical direction on the side wall of the sliding seat 9, and the second power component is an existing reciprocating drive component such as an electric push rod 27. The purpose of such a setting is that when the supporting mechanism (referring to the top plate 8 in this embodiment) is in the second position When the bolt 11 is in the first state, the bolt 11 is plugged into the socket 12. When the supporting mechanism switches from the second position to the first position, the cylinder 7 is started, and the output end of the cylinder 7 is extended, thereby driving the lifting plate 4 and the upright 5 to move vertically upward, and under the action of the plugging of the bolt 11 and the socket 12, the top plate 8 is driven to move upward synchronously. When one of the top plates 8 abuts against the connecting portion 3 at the lowest position, the bolt 11 corresponding to the top plate 8 is then controlled by the second power component to switch from the first state to the second state, so that the bolt 11 is connected to one of the positioning holes 13, so that the top plate 8 is connected to the sliding seat 9 as a whole (that is, in During the subsequent upward movement of the vertical pole 5, the top plate 8 will not continue to be driven to move upward), so that the top plate 8 is fixed in the first position to achieve the supporting effect, and then the remaining top plates 8 are controlled to continue to move upward by the cylinder 7. When another top plate 8 abuts against the second lowest connection part 3, the above operation will be repeated, and so on. The adaptive adjustment of the height of multiple top plates 8 can be achieved. When the vertical pole 5 moves vertically downward, when the socket 12 drops to be coaxial with the latch 11, the second power component controls the latch 11 to switch from the second state to the first state, so that the top plate 8 is connected to the vertical pole 5, and when the vertical pole 5 drops, the top plate 8 is automatically reset to prepare for the next support.

[0039] Preferably, the positioning hole 13 is configured with an opening, and the opening, that is, the entrance area of ​​the positioning hole 13 is larger than the internal area thereof, so as to facilitate the insertion of the latch 11 into the positioning hole 13 .

[0040] As another embodiment of the present invention, a support rod 16 is elastically arranged on the top plate 8, and a lifting groove 17 is opened at the top end of the top plate 8. The support rod 16 is slidably connected with the lifting groove 17. The elastic setting here is that a first spring 18 is arranged between the bottom end of the support rod 16 and the lifting groove 17, and in this embodiment, the connecting part 3 is located on the movement stroke of the support rod 16. The effect of such a setting is that in the process of the top plate 8 driving the support rod 16 to move upward, the support rod 16 will abut against the connecting part 3 to achieve a supporting effect, and the first spring 18 can buffer the force between the support rod 16 and the connecting part 3, thereby avoiding damage to the connecting part 3.

[0041] As another embodiment of the present invention, the second power component includes an elastic telescopic rod 19, an active cavity 20 is opened inside the top plate 8, a first rotating seat 21 is arranged on the inner wall of the active cavity 20, and a second rotating seat 22 is arranged on the latch 11, and both ends of the elastic telescopic rod 19 are rotatably connected with the first rotating seat 21 and the second rotating seat 22 respectively; a transmission member for driving the second rotating seat 22 to move horizontally is arranged between the support rod 16 and the second rotating seat 22, and the transmission member includes a transmission rod 23, an abutment rod 24 is rotatably arranged on the inner wall of the active cavity 20, one end of the transmission rod 23 is fixedly connected to the support rod 16, and the other end of the transmission rod 23 abuts against the abutment rod 24, and the second rotating seat 22 is located on the rotation stroke of the abutment rod 24. Specifically, the elastic telescopic rod 19 can be extended or contracted, and has the ability of automatic recovery through elastic components such as springs. force, and the elastic component is always in a compressed state. When the latch 11 is in the first state, the elastic telescopic rod 19 tilts to the left, and when the latch 11 is in the second state, the elastic telescopic rod 19 tilts to the right. In this embodiment, the latch 11 includes a first section 1101 and a second section 1102 that are slidably connected to each other, and the second rotating seat 22 is fixedly connected to the first section 1101. A second spring 25 is arranged between the first section 1101 and the second section 1102. When the latch 11 is in the first state and the second state, the second spring 25 is in a natural state. The first rotating seat 21 and the second rotating seat 22 are both provided with a rotating shaft. Both ends of the elastic telescopic rod 19 are provided with a rotating hole, and the two rotating holes are respectively rotatably connected with the two rotating shafts. The transmission rod 23 is fixedly connected to the lower surface of the support rod 16, and the transmission rod 23 penetrates into the active cavity 20. A horizontal axis 26 is arranged in the active cavity 20, and the abutment rod 24 can rotate vertically around the horizontal axis 26. Figure 8As shown, the abutment rod 24 is approximately "S"-shaped, with a horizontal portion 2401 at its top and an abutment portion 2402 at its bottom. The bottom end of the transmission rod 23 abuts against the horizontal portion 2401, and the second rotating seat 22 is located on the movement stroke of the abutment portion 2402. The horizontal axis 26 is arranged at the first inflection point position at the top of the abutment rod 24, and a torsion spring (not shown in the figure) is arranged between the abutment rod 24 and the horizontal axis 26. The elastic force of the torsion spring makes the abutment rod 24 have a tendency to rotate counterclockwise. Specifically, when the top end of the support rod 16 abuts against the connecting portion 3, the support rod 16 is forced to move downward and squeeze the first spring 18. The support rod 16 will synchronously drive the transmission rod 23 to move vertically downward, thereby driving the bottom end of the transmission rod 23 to abut against the horizontal portion 2401 of the abutment rod 24, so that the abutment rod 24 rotates around the horizontal axis 26 in the clockwise direction. The elastic telescopic rod 19 rotates clockwise, and the abutting portion 2402 of the abutting rod 24 abuts against the side wall of the second rotating seat 22, thereby pushing the second rotating seat 22 to move horizontally, and driving the elastic telescopic rod 19 to rotate clockwise around the first rotating seat 21. During the rotation process, the distance between the first rotating seat 21 and the first rotating seat 21 is first shortened and then increased, that is, when the elastic telescopic rod 19 is in the vertical state, the elastic telescopic rod 19 is in the shortest state, and the elastic component inside the elastic telescopic rod 19 is compressed to the limit value at this time. After the elastic telescopic rod 19 rotates through the vertical state, the elastic force of the elastic component inside it is instantly released, thereby driving the elastic telescopic rod 19 to extend. During the extension of the elastic telescopic rod 19, it will drive the latch 11 to be instantly inserted into the positioning hole 13, so as to realize the passive switching of the latch 11 from the first state to the second state.

[0042] Further, the second power assembly also includes a push rod 27, which is elastically arranged inside the sliding seat 9, and a plurality of push parts 28 are arranged on the push rod 27, and the plurality of push parts 28 are arranged one by one with the plurality of positioning holes 13. A first abutment block 29 is arranged on the push rod 27, and a second abutment block 30 is arranged on the lifting plate 4. The first abutment block 29 is located on the movement stroke of the second abutment block 30. Specifically, an avoidance groove 31 is opened inside the sliding seat 9, and the push rod 27 is slidably arranged in the avoidance groove 31. The elastic setting here is that a third spring 32 is arranged between the push rod 27 and the avoidance groove 31, and the elastic force of the third spring 32 has the effect of making The push rod 27 tends to move away from the positioning hole 13, and multiple pushing parts 28 are evenly arranged on the push rod 27 and penetrate into the positioning hole 13. A rectangular hole 33 is opened on the lifting plate 4, and the second abutment block 30 is arranged on the lower surface of the lifting plate 4. The first abutment block 29 is connected to the bottom end of the push rod 27 by a connecting rod, and the first abutment block 29 penetrates the rectangular hole 33 and is located below the second abutment block 30, and the first abutment block 29 and the second abutment block 30 are both provided with wedge-shaped surfaces. The effect of such a setting is that when the cylinder 7 drives the lifting plate 4 to move vertically downward, since the latch 11 is in the second state at this time, the top plate 8 will not move downward with the vertical rod 5, so that the latch 11 and the socket 12 are offset. The wedge-shaped surface of the second abutting block 30 abuts against the wedge-shaped surface of the first abutting block 29, thereby driving the push rod 27 to move in the direction of the positioning hole 13, further stretching the third spring 32, and making the plurality of pushing portions 28 synchronously inserted into the positioning holes 13, and abutting against the latch 11 inside the positioning hole 13, so that the latch 11 slides in the direction of the insertion hole 12, and driving the elastic telescopic rod 19 to automatically reset. Since the latch 11 is not coaxial with the insertion hole 12 at this time, the abutment of the pushing portion 28 and the latch 11 will make the second section 1102 abut against the side of the vertical rod 5, so that the second section 1102 slides into the first section 1101 and squeezes the second spring 25. To achieve avoidance, at this time, the latch 11 is between the pushing portion 28 and the vertical rod 5, and both ends of the latch 11 are not connected with the socket 12 and the positioning hole 13, that is, at this time, the top plate 8 is in a disconnected state with the sliding seat 9 and the vertical rod 5, and the top plate 8 moves vertically downward under the action of its own gravity. At this time, the elastic force of the first spring 18 is released, thereby driving the transmission rod 23 and the abutment rod 24 away from each other, and the abutment rod 24 automatically resets under the elastic force of the torsion spring. When the top plate 8 drives the latch 11 to move coaxially with the socket 12, the elastic force of the second spring 25 is released, thereby allowing the second section 1102 to be inserted into the socket 12, so as to realize the passive switching of the latch 11 from the second state to the first state.

[0043] The support rod 16 is elastically provided with an extrusion plate 34, and a connecting frame 35 is provided on the extrusion plate 34. The connecting frame 35 is provided with a third abutment block 36. The vertical rod 5 is provided with a fourth abutment block 37. The third abutment block 36 is located on the movement stroke of the fourth abutment block 37. Specifically, a transverse groove 38 is provided on the top of the top plate 8, and the extrusion plate 34 is slidably connected to the transverse groove 38. The elastic setting here is that a fourth spring 39 is provided between the extrusion plate 34 and the transverse groove 38. When the support rod 16 abuts against the connecting portion 3, the extrusion plate 34 is located on one side of the terminal 2, and the connecting frame 35 is sleeved on the outside of the support rod 16. The third abutment block 36 is provided on the lower surface of the connecting frame 35, and the fourth abutment block 37 is provided on the top of the vertical rod 5. The third abutment block 36 and the fourth abutment block 37 are both provided with wedge surfaces, and the wedge surface of the third abutment block 36 is located at the wedge surface of the fourth abutment block 37. In terms of the movement stroke, the fourth abutment block 37 is arranged to avoid interference with the connecting part 3 and the cable when the fourth abutment block 37 moves upward. The effect of such an arrangement is that after the top plate 8 switches from the second position to the first position, it will not continue to move upward, but the vertical rod 5 will continue to move upward under the action of the cylinder 7, so that the wedge surface of the fourth abutment block 37 abuts against the wedge surface of the third abutment block 36, so that under the action of the connecting frame 35, the extrusion plate 34 slides toward the position of the terminal 2 and stretches the fourth spring 39, thereby exerting an extrusion effect on the terminal 2, so that the terminal 2 is tightly plugged into the interface, thereby preventing the terminal 2 from falling off. When the vertical rod 5 moves vertically downward, the fourth abutment block 37 and the third abutment block 36 are driven away. At this time, the elastic force of the fourth spring 39 is released, so that the extrusion plate 34 is separated from the terminal 2, so that the extrusion plate 34 and the third abutment block 36 are automatically reset.

[0044] Furthermore, a locking rod 40 is provided on the third abutment block 36, and a plurality of locking holes 41 are provided on the support rod 16. Specifically, the locking rod 40 is fixedly connected to the surface of the third abutment block 36 close to the support rod 16, and is slidably connected to the side wall of the top plate 8. The plurality of locking holes 41 are evenly arranged in the vertical direction of the support rod 16. When the fourth abutment block 37 abuts against the third abutment block 36 and drives the connecting frame 35 to move horizontally, the locking rod 40 will be plugged into one of the locking holes 41, thereby locking the position of the support rod 16, so that the elastic support of the support rod 16 becomes a fixed support. At this time, the elastic force of the first spring 18 will not be transmitted to the connecting portion 3 to prevent the connecting portion 3 from being always in a stressed state, thereby preventing the connecting portion 3 from being damaged. After the fourth abutment block 37 is separated from the third abutment block 36, the connecting frame 35 will drive the locking rod 40 to be pulled out of the locking hole 41 under the elastic force of the fourth spring 39 to realize the automatic resetting of the locking rod 40.
