DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] The present invention provides a central air-conditioning energy-saving control cabinet with strong and weak electricity integration, such as Figures 1 to 9 As shown, it includes a cabinet 1, a bracket 2 is fixedly installed inside the cabinet 1, a cable management rack 3 is fixedly installed on the inner side of the bracket 2 at equidistant intervals from top to bottom, a carrier plate 4 is fixedly installed inside the bracket 2 and between adjacent cable management racks 3, a rectangular shell 5 is fixedly installed on the rear side of the carrier plate 4 at equidistant intervals, a slide bar 6 is slidably installed inside the rectangular shell 5, and a limiting component for limiting the position of the slide bar 6 is provided on the outside of the slide bar 6, a first spring 7 is provided at the end of the slide bar 6 away from the carrier plate 4, a groove corresponding to the slide bar 6 is opened on the front side of the carrier plate 4, a ball head 8 is fixedly installed in the groove at the end of the slide bar 6 close to the carrier plate 4, a mounting plate 11 is sleeved on the outside of the ball head 8, a connecting plate 9 is fixedly sleeved on the outside of the slide bar 6, a second spring 10 is sleeved on the outside of the slide bar 6 and located between the connecting plate 9 and the mounting plate 11, and two ends of the second spring 10 are fixedly connected to the mounting plate 11 and the connecting plate 9 respectively, a device 12 is fixedly installed on the front side of the mounting plate 11, and a positioning component for limiting its movement is provided on the mounting plate 11.

[0029] During use, when it is necessary to repair the device 12, the limit of the slide bar 6 by the limit assembly is cancelled. At this time, the compressed first spring 7 releases the force to move the slide bar 6, the ball head 8, the mounting plate 11, and the device 12 in a direction away from the carrier plate 4, so that the device 12 leaves its adjacent device 12 and can extend beyond the adjacent device 12. At this time, due to the extension of the device 12, the device 12 will not be affected by the adjacent device 12 when being repaired, which is convenient for operation. The restriction of the positioning assembly on the mounting plate 11 can be cancelled. At this time, the mounting plate 11 can be rotated. The mounting plate 11 is rotated relative to the ball head 8. During the rotation process, the second spring 10 is deformed by the force brought by the mounting plate 11. When it is necessary to fix the mounting plate 12, the second spring 10 is deformed. The plate 11 is then released, and the restriction on the mounting plate 11 by the positioning assembly is restored. At this time, the mounting plate 11 cannot move and maintains the required state, which is convenient for maintenance. Through the movement of the mounting plate 11, the device 12 can be moved with it, and then the maintenance angle of the device 12 can be adjusted to improve the convenience of maintenance. After the maintenance is completed, the restriction on the mounting plate 11 is cancelled, and the deformed second spring 10 releases the force to restore the mounting plate 11. Then, the positioning of the mounting plate 11 by the positioning assembly can be restored, and the mounting plate 11 can be pressed to restore it with the ball head 8 and the slide rod 6. The slide rod 6 compresses the first spring 7 to deform it and generate a force. Then, the slide rod 6 can be limited by the limiting assembly to fix the slide rod 6 to complete the reset of the device 12.

[0030] like Figure 6 to Figure 7 As shown, the limit assembly includes a rectangular plate 13 fixedly mounted on the end of the slide rod 6 away from the carrier plate 4, a rectangular rod 14 is slidably inserted through the rear side of the carrier plate 4, the top of the rectangular rod 14 is fixedly connected with a clamping block 17 through a cross plate 16, a third spring 15 is sleeved on the outside of the rectangular rod 14, the two ends of the third spring 15 are respectively fixedly connected to the cross plate 16 and the carrier plate 4, the top of the clamping block 17 is provided with an inclined surface facing the carrier plate 4, the top of the clamping block 17 extends to the inside of the rectangular shell 5, the bottom end of the rectangular rod 14 is fixedly connected with a pull rope 18, and the end of the pull rope 18 away from the rectangular rod 14 is fixedly connected with a pull ring 19.

[0031] Pull the pull ring 19 to cooperate with the pull rope 18 to bring the rectangular rod 14, the horizontal plate 16, and the block 17 down, so that the third spring 15 is compressed and deformed to generate a force, and the block 17 is lowered to separate from the rectangular plate 13. At this time, the compressed first spring 7 releases the force to bring the rectangular plate 13, the slide bar 6, the ball head 8, the mounting plate 11, and the device 12 away from the carrier plate 4. When the rectangular plate 13 is separated from the block 17, the pull ring 19 is released, and the compressed third spring 15 releases the force to bring the horizontal plate 16 , the block 17 rises and resets. When the slide bar 6 and the rectangular plate 13 are reset, the rectangular plate 13 conflicts with the inclined surface of the block 17, and the inclined surface squeezes the block 17 to make it fall. Similarly, the third spring 15 is compressed and deformed to generate a force. When the rectangular plate 13 is reset and separated from the top of the block 17, the compressed third spring 15 releases the force to realize the rising and resetting of the block 17, so that the block 17 conflicts with the rectangular plate 13, restricts the rectangular plate 13, and makes it unable to move, thereby completing the reset of the device 12.

[0032] like Figure 6 and Figure 8 As shown, the positioning assembly includes a pair of clamps 29, and the outside of the mounting plate 11 is symmetrically provided with sliding grooves, which are connected to the area where the ball head 8 is located. The clamps 29 are slidably set in the sliding grooves, and a rubber pad is provided on the side of the clamps 29 close to the ball head 8, and the side of the clamps 29 away from the ball head 8 is set as an arc surface. The outside of the mounting plate 11 is symmetrically provided with vertical grooves, and a pressure plate 30 is slidably installed in the vertical grooves. The bottom of the pressure plate 30 is fixedly connected to the bottom wall of the vertical groove by a fourth spring 31, and a circular ring is provided at the bottom of the pressure plate 30, and the top of the pressure plate 30 is in contact with the arc surface.

[0033] Pulling a pair of pressure plates 30 to make them descend compresses the fourth spring 31, causing its deformation to generate a force, causing the pressure plate 30 to leave the center of the arc surface. At this time, the pressure plate 30 cancels the squeezing of the clamping plate 29. At this time, the ball head 8 and the mounting plate 11 can move relative to each other. Release the pressure plate 30, and the compressed fourth spring 31 releases the force to carry the pressure plate 30 up and reset, so that the arc surface of the clamping plate 29 squeezes the clamping plate 29, so that the clamping plate 29 cooperates with the rubber pad to squeeze the ball head 8. Through the friction between the rubber pad and the ball head 8, the mounting plate 11 cannot move relative to the ball head 8, thereby realizing the positioning of the mounting plate 11.

[0034] like Figure 6 and Fig. 9 As shown, the top and bottom of the cable management rack 3 are equidistantly provided with cover plates 20, the top of the cover plate 20 is symmetrically provided with threading holes, a clamp ring 21 is slidably installed in the threading hole, a rubber ring is provided on the inner side of the clamp ring 21, and an extrusion component for driving it to move away from the cable management rack 3 is provided on the outside of the cover plate 20, and the rubber ring is an annular rubber airbag.

[0035] Since the wiring harness of the device 12 is in a rigid state, and most of it is in the wire management rack 3, and the wiring harness outside the wire management rack 3 is in a vertical state, when the angle of the mounting plate 11 is adjusted, the device 12 will move with it and pull the wiring harness excessively, causing the connection between the wiring harness and the device 12 to easily fall off, and due to the rigidity of the wiring harness itself, it is very laborious to adjust the angle of the mounting plate 11. When the wiring harness below the device 12 is being managed, the wiring harness is passed through the rubber ring, and the rest of the wiring harness is placed in the wire management rack 3. After the wiring harness is arranged in a vertical state, the rubber ring can be inflated to expand it, thereby squeezing it tightly and fixing it. When the device 12 moves away from the carrier plate 4, the wiring harness moves with it. Since the wiring harness is in a rigid state, the wiring harness moves with it against the clamp ring 21. The wiring harness in the vertical state will not contact the wiring harness on the device 12 next door, so it will not be hindered. To ensure that the device 12 can move outward smoothly, when the device 12 leaves the adjacent device 12, the extrusion assembly extrudes the cover plate 20 to move in the direction close to the device 12, and the cover plate 20 moves with the clamp ring 21 and the rubber ring, so that the wire harness moves with the friction force, so that the wire harness is bent, so that when the position of the mounting plate 11 is subsequently adjusted, the connection between the device 12 and the wire harness will not be excessively pulled by the wire harness, and the connection between the device 12 and the wire harness is protected, ensuring that the mounting plate 11 can be easily adjusted for angles. When the mounting plate 11 is reset, the device 12 moves accordingly, and the extrusion assembly cancels the extrusion of the cover plate 20, and the cover plate 20 is reset, so that the clamp ring 21 and the rubber ring are used to straighten the wire harness, and then the wire harness is reset. During the reset process, the wire harness is in a straightened state, so it will not conflict with the wire harness on the adjacent device 12, and will not be hindered, ensuring the smooth reset of the device 12.

[0036] like Figure 6 As shown, the extrusion assembly includes a push rod 28 symmetrically fixedly installed on the rear side of the cover plate 20, round rods 22 are fixedly installed on the four corners of the side of the cover plate 20 close to the cable management frame 3, and a round plate 23 is fixedly installed on the end of the round rod 22 away from the cover plate 20. A cavity corresponding to the round plate 23 is opened on the cable management frame 3, and the round plate 23 and the round rod 22 are slidably arranged in the cavity. A fifth spring 24 is sleeved on the outside of the round rod 22, and the two ends of the fifth spring 24 respectively contact the round plate 23 and the inner wall of the cavity, a connecting rod 25 is fixedly installed on the end of the rectangular plate 13 away from the carrier plate 4, and the end of the connecting rod 25 away from the carrier plate 4 extends to the outside of the rectangular shell 5 and is symmetrically fixedly installed with an extrusion plate 26, and a wedge-shaped surface 27 facing the carrier plate 4 is provided on the side of the extrusion plate 26 close to the push rod 28.

[0037] When the slide bar 6 moves with the ball head 8, the mounting plate 11, and the device 12 in the direction away from the carrier plate 4, the connecting rod 25 and the squeezing plate 26 move accordingly. When the device 12 is separated from the adjacent device 12, the wedge surface 27 contacts the end of the push rod 28 to squeeze the push rod 28 so that it moves with the cover plate 20 in the direction close to the device 12. The cover plate 20 moves with the round rod 22 and the round plate 23 and cooperates with the cavity to compress the fifth spring 24 to deform it and generate a force. When the slide bar 6 returns to its original position with the ball head 8, the mounting plate 11, and the device 12, the squeezing plate 26 moves accordingly, the wedge surface 27 is separated from the push rod 28, and the compressed fifth spring 24 releases its force to return the round plate 23, the round rod 22, and the cover plate 20 to their original position.

[0038] like Figure 6 and Fig. 9 As shown, a cable passing hole is provided on the cover plate 20 below the pull rope 18 , and the pull rope 18 passes through the cable passing hole. The pull ring 19 is located in front of the cable management frame 3 .

[0039] This makes it easy to position the drawstring 18 and to pull the drawstring 18 in cooperation with the pull ring 19 .

[0040] like Figure 4 As shown, the threading openings on the cover plate 20 are symmetrically arranged on both sides of the device 12 , and the position and number of the cover plate 20 correspond to those of the device 12 .

[0041] This makes it easier to carry out the wiring installation of the wiring harness of the device 12 .

[0042] like Figure 4 As shown, an operation opening is provided on the front side of the cable management frame 3, and a closing plate is provided in the operation opening.

[0043] The closing plate is connected to the cable management frame 3 by screws. The screws can be removed, the closing plate can be removed, and the operation port can be opened to organize the internal wire harness.

[0044] Working principle: When in use, when the device 12 needs to be repaired, the pull ring 19 is pulled to cooperate with the pull rope 18 to bring the rectangular rod 14, the horizontal plate 16, and the block 17 down, so that the third spring 15 is compressed and deformed to generate a force, and the block 17 is lowered to separate from the rectangular plate 13. At this time, the compressed first spring 7 releases the force to bring the rectangular plate 13, the slide bar 6, the ball head 8, the mounting plate 11, and the device 12 to move away from the carrier plate 4. When the rectangular plate 13 is separated from the block 17, the pull ring 19 is released, and the compressed third spring 15 releases the force to bring the horizontal plate 16 and the block 17 up and reset. As the device 12 moves, the device 12 is separated from its adjacent device 12, so that it can stretch The device 12 is extended out of the adjacent device 12. At this time, due to the extension of the device 12, the device 12 will not be affected by the adjacent device 12 when being repaired, which is convenient for operation. The pair of pressure plates 30 are pulled down to compress the fourth spring 31, so that its deformation generates a force, so that the pressure plate 30 leaves the center of the arc surface. At this time, the pressure plate 30 cancels the squeezing of the clamping plate 29. At this time, the ball head 8 and the mounting plate 11 can move relative to each other. At this time, the mounting plate 11 can be rotated. The mounting plate 11 is rotated to rotate relative to the ball head 8. During the rotation process, the second spring 10 is deformed by the force brought by the mounting plate 11. When the mounting plate 11 needs to be fixed, the pressure plate 3 is released. 0, the compressed fourth spring 31 releases its force and brings the pressure plate 30 up and back to its original position, so that the arc surface of the matching clamping plate 29 squeezes the clamping plate 29, so that the clamping plate 29 cooperates with the rubber pad to squeeze the ball head 8 tightly, and the friction between the rubber pad and the ball head 8 makes the mounting plate 11 unable to move relative to the ball head 8, thereby realizing the positioning of the mounting plate 11. At this time, the mounting plate 11 cannot move and maintains the required state, which is convenient for maintenance. Through the movement of the mounting plate 11, the device 12 can be moved with it, and then the maintenance angle of the device 12 can be adjusted, thereby improving the convenience of maintenance. After the maintenance is completed, the restriction on the mounting plate 11 is cancelled again as above, and the deformed second spring 10 The force is released to reset the mounting plate 11, and then the restriction on the mounting plate 11 is restored. The mounting plate 11 is pressed to reset it with the ball head 8 and the slide bar 6. The slide bar 6 compresses the first spring 7 to deform it and generate a force. When the slide bar 6 and the rectangular plate 13 are reset, the rectangular plate 13 contacts the inclined surface of the block 17, and the block 17 is squeezed by the inclined surface to make it fall. Similarly, the third spring 15 is compressed and deformed to generate a force. When the rectangular plate 13 is reset and separated from the top of the block 17, the compressed third spring 15 releases the force to realize the upward reset of the block 17, so that the block 17 contacts the rectangular plate 13, restricts the rectangular plate 13, and makes it unable to move, thereby completing the reset of the device 12.Since the wire harness of the device 12 is in a rigid state and most of it is in the wire management rack 3, the wire harness outside the wire management rack 3 is in a vertical state. When the angle of the mounting plate 11 is adjusted, the device 12 will move with it and pull the wire harness excessively, causing the connection between the wire harness and the device 12 to fall off easily. In addition, due to the rigidity of the wire harness itself, it is very laborious to adjust the angle of the mounting plate 11. When the wire harness under the device 12 is being managed, the wire harness is passed through the rubber ring, and the rest of the wire harness is placed in the wire management rack 3. After the wire harness is managed in a vertical state, it can be moved to the rubber ring. The ring is inflated to expand, so that it is squeezed tightly with the wire harness and fixed. When the device 12 moves away from the carrier plate 4, the wire harness moves with it. Since the wire harness is in a rigid state, the wire harness moves with it against the clamp ring 21. The wire harness in the vertical state will not contact the wire harness on the device 12 next door, so it will not be hindered, ensuring that the device 12 can move outward smoothly. When the slide bar 6 moves with the ball head 8, the mounting plate 11, and the device 12 away from the carrier plate 4, the connecting rod 25 and the squeezing plate 26 move with it. When the device 12 leaves the adjacent After the device 12 is installed, the wedge-shaped surface 27 contacts the end of the push rod 28, so that the push rod 28 is squeezed to make it move with the cover plate 20 in the direction close to the device 12, and the cover plate 20 moves with the round rod 22 and the round plate 23, and the cavity compresses the fifth spring 24 to deform it and generate a force, and the cover plate 20 moves with the clamp ring 21 and the rubber ring, so that the wire harness moves with the friction force, so that the wire harness is bent, so that when the position of the mounting plate 11 is adjusted later, the connection between the device 12 and the wire harness will not be excessively pulled by the wire harness, thereby protecting the device 12. At the connection with the harness, the mounting plate 11 is ensured to be easy to adjust the angle. When the mounting plate 11 is reset, the device 12 moves accordingly. At this time, the squeeze plate 26 moves accordingly, the wedge surface 27 is separated from the top rod 28, and the compressed fifth spring 24 releases the force to reset the circular plate 23, the round rod 22, and the cover plate 20, so that the clamp ring 21 and the rubber ring straighten the harness, and then the harness is reset. During the reset process, the harness is in a straightened state, so it will not conflict with the harness on the adjacent device 12, and will not be hindered, ensuring the smooth reset of the device 12. ;

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
