[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] like Figure 1-Figure 8 As shown, the electrical equipment control cabinet of this embodiment includes a configuration frame 1, a protective cover 2 and a guide assembly 4. The configuration frame 1 is slidably connected to the protective cover 2 through the guide assembly 4. The configuration frame 1 and the protective cover 2 are combined to form a rectangular body. A locking assembly 5 is arranged inside the configuration frame 1. When the protective cover 2 is closed, the top of the locking assembly 5 is fixed to the protective cover 2.

[0035] The present invention uses a pull-out protective cover 2 to replace the switch door, and uses a locking assembly 5 to fix the protective cover 2. When the protective cover 2 is opened, there are fewer side walls blocking the surroundings, and the operator has a larger operating space.

[0036] Furthermore, the guide assembly 4 includes a limit sleeve 6, a guide rod 7 and a limit block 8, one end of the guide rod 7 is fixed to the protective cover 2, the other end of the guide rod 7 is fixed to the limit block 8, and the top of the limit block 8 is fixed to the protective cover 2; the limit sleeve 6 is sleeved on the outer periphery of the guide rod 7 and is slidably connected to the guide rod 7, and the side wall of the limit sleeve 6 is fixed to the configuration frame 1.

[0037] The limiting block 8 cooperates with the side wall of the protective cover 2 to fix the guide rod 7 , and the protective cover 2 is slidably connected to the guide rod 7 through the limiting sleeve 6 .

[0038] Furthermore, the locking assembly 5 includes a driving gear 9, a locking rod 10, a spring 12 and a knob 14. The driving gear 9 is clearance-matched with the inner wall of the configuration frame 1. The central axis of the knob 14 passes through the side wall of the configuration frame 1 and is fixed to the center of the knob 14. The locking rod 10 is L-shaped. The bottom of the locking rod 10 is fixed to the top of the spring 12, and the bottom of the spring 12 is fixed to the bottom of the inner cavity of the configuration frame 1. The side wall of the locking rod 10 is provided with meshing teeth 11. The locking rod 10 is meshed with the driving gear 9 through the meshing teeth 11. The outer wall of the locking rod 10 above the meshing teeth 11 is slidably matched with the guide sleeve 13, and the guide sleeve 13 is fixed to the inner wall of the configuration frame 1. A card slot 15 is provided at the bottom of the protective cover 2. When the configuration frame 1 and the protective cover 2 are closed, the top of the locking rod 10 is engaged with the inside of the card slot 15.

[0039] When it is necessary to operate the electronic components 16 inside the configuration frame 1, the knob 14 is turned, and the knob 14 drives the driving gear 9 to rotate. The rotating driving gear 9 drives the locking rod 10 to move downward through the meshing teeth 11, so that the upper end of the locking rod 10 is separated from the card slot 15. At this time, the protective cover 2 is pulled outward, and the second roller 17 drives the protective cover 2 to move smoothly. The protective cover 2 drives the guide rod 7 to move along the limiting sleeve 6 to separate the configuration frame 1 and the protective cover 2, so that the configuration frame 1 is exposed, which is convenient for the staff to install or repair the electrical equipment in the configuration frame 1.

[0040] After the installation or maintenance of the electronic component 16 is completed, the protective cover 2 is pushed inward so that the protective cover 2 completely covers the outside of the configuration frame 1. At this time, the knob 14 is reversed, and the knob 14 drives the locking rod 10 to move upward through the driving gear 9. At the same time, the spring 12 pushes the locking rod 10 to move upward along the guide sleeve 13 until the locking rod 10 engages with the card slot 15, fixing the configuration frame 1 and the protective cover 2 together to prevent the configuration frame 1 and the protective cover 2 from separating.

[0041] Furthermore, a first roller 3 is disposed at the bottom of the configuration frame 1 , and a second roller 17 is disposed at the bottom of the protective cover 2 .

[0042] According to the needs of use, the control cabinet can be moved to a specified position by the first roller 3, and then the first roller 3 can be locked to fix the control cabinet; the second roller 17 can assist the protective cover 2 in moving.

[0043] Furthermore, a linkage device 18 is provided inside the configuration frame 1 , one end of the linkage device 18 is connected to the driving gear 9 , and the other end of the linkage device 18 is connected to the protective cover 2 .

[0044] The locking assembly 5 and the protective cover 2 are connected by a linkage device 18 , and when the knob 14 is turned, the linkage device 18 can simultaneously drive the protective cover 2 to move.

[0045] Furthermore, the linkage device 18 includes a first linkage gear 19, a conveyor belt 20, a second linkage gear 21, a threaded sleeve 22 and a threaded column 27. The first linkage gear 19 is concentrically fixed to the top of the driving gear 9, and the second linkage gear 21 is arranged at the bottom of the inner cavity of the configuration frame 1 through a mounting frame 23. One end of the conveyor belt 20 is meshed with the first linkage gear 19, and the other end of the conveyor belt 20 is meshed with the second linkage gear 21; one end of the threaded sleeve 22 is fixed to the second linkage gear 21, and the other end of the threaded sleeve 22 is threadedly connected to the inner wall and the outer wall of one end of the threaded column 27, and the other end of the threaded column 27 is rotatably matched with the side wall of the protective cover 2.

[0046] The first linkage gear 19 is arranged concentrically with the driving gear 9. When the knob 14 is turned, the knob 14 drives the driving gear 9 to rotate, and the driving gear 9 drives the first linkage gear 19 to rotate. The first linkage gear 19 drives the second linkage gear 21 to rotate through the conveyor belt 20, and the second linkage gear 21 drives the threaded sleeve 22 to rotate. The threaded sleeve 22 drives the threaded column 27 to extend / contract inside the threaded sleeve 22, and the threaded column 27 drives the protective cover 2 to move.

[0047] Furthermore, one end of the second linkage gear 21 is fixed to the first toothed disc 25, and one end of the threaded sleeve 22 is fixed to the second toothed disc 26; the length of the threaded section of the threaded column 27 is less than the length of the guide rod 7; when the protective cover 2 is moved, the first toothed disc 25 is meshed with the second toothed disc 26, and when the protective cover 2 is located at the outermost end, the first toothed disc 25 is separated from the second toothed disc 26.

[0048] By setting the first toothed disc 25 and the second toothed disc 26, when the second linkage gear 21 rotates, the second linkage gear 21 drives the first toothed disc 25 to rotate, and the first toothed disc 25 drives the threaded sleeve 22 to rotate through the second toothed disc 26. Since the length of the threaded section of the threaded column 27 is less than the length of the guide rod 7, when the protective cover 2 is driven to move by the knob 14, the protective cover 2 will not move to the limit distance, and the first toothed disc 25 and the second toothed disc 26 are always in a meshing state; if it is necessary to perform a long-term maintenance on the inside of the configuration frame 1, the protective cover 2 can be manually pulled outward, and the first toothed disc 25 and the second toothed disc 26 are separated. When the second roller 17 is locked, it can be ensured that the protective cover 2 will not move easily; after completing the maintenance of the electronic component 16, the second roller 17 is unlocked, and the protective cover 2 is pushed back to re-engage the first toothed disc 25 and the second toothed disc 26, and the protective cover 2 can be driven to reset by reversing the knob 14, and at the same time, the top of the locking rod 10 is re-engaged in the slot 15.

[0049] Furthermore, a buffer device 24 is provided between one end of the second linkage gear 21 and the first gear plate 25 .

[0050] When the protective cover 2 is pushed back, the first toothed disc 25 and the second toothed disc 26 may collide with each other, and the buffer device 24 can offset the force generated by the collision between the first toothed disc 25 and the second toothed disc 26 .

[0051] The method for using the electrical equipment control cabinet of this embodiment includes the following steps:

[0052] The knob 14 is turned, and the knob 14 drives the top of the locking rod 10 to disengage from the slot 15 through the driving gear 9 and the meshing teeth 11 .

[0053] The driving gear 9 drives the first toothed disc 25 to rotate through the first linkage gear 19, the conveyor belt 20 and the second linkage gear 21. The first toothed disc 25 drives the threaded sleeve 22 to rotate through the second toothed disc 26. The threaded sleeve 22 drives the threaded column 27 to extend and drives the protective cover 2 to move outward; when the second linkage gear 21 rotates, the second linkage gear 21 drives the first toothed disc 25 to rotate. The first toothed disc 25 drives the threaded sleeve 22 to rotate through the second toothed disc 26. Since the length of the threaded section of the threaded column 27 is less than the length of the guide rod 7, when the protective cover 2 is driven to move by the knob 14, the protective cover 2 will not move to the limit distance, and the first toothed disc 25 and the second toothed disc 26 are always in a meshing state.

[0054] If the protective cover 2 needs to be opened for a long time, the protective cover 2 can be manually pulled outward to separate the first toothed disc 25 from the second toothed disc 26, and then the second roller 17 is locked to ensure that the protective cover 2 will not move easily.

[0055] When closing the protective cover 2, manually push the protective cover 2 back to re-engage the first toothed disc 25 and the second toothed disc 26, and then reverse the knob 14 to drive the protective cover 2 and make the top of the locking rod 10 engage with the slot 15. After the installation or maintenance of the electronic component 16 is completed, push the protective cover 2 inward to re-engage the first toothed disc 25 and the second toothed disc 26, and then reverse the knob 14 to drive the protective cover 2 to reset, and at the same time, make the top of the locking rod 10 re-engage in the slot 15 to prevent the configuration frame 1 and the protective cover 2 from separating.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
