After installation, rotate and close the cabinet door 2, and engage the locking member 11 inside the cabinet door 2 with the abutting block 3

[0034] Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above Embodiment 1. After the existing door lock is used for a long time, in order to ensure its stability and safety, regular maintenance is required. When disassembling and reassembling, it is easier to damage or lose components, increasing the maintenance cost and time. This technical solution is as Figures 1-4 and Figure 8 、 Figure 9As shown, an installation component of a switch cabinet is disclosed. A fixing member 4 is fixedly connected inside a cabinet door 2. A through slot 401 is formed in the middle of the fixing member 4. A limiting hole 402 is formed in the inner wall of the slot 401. A base 5 is arranged in the slot 401. The base 5 and the fixing member 4 are connected by a connecting mechanism 6. The connecting mechanism 6 includes a fixing block 601. The fixing block 601 is fixedly arranged in the slot 401. Two fixing blocks 601 are symmetrically arranged with respect to the slot 401. The connecting mechanism 6 further includes a bolt 602, a cam 603, an auxiliary spring 604 and a limiting post 605. The bolt 602 is slidably arranged in the base 5. An auxiliary spring 604 is sleeved outside the bolt 602. One end of the auxiliary spring 604 is fixedly connected to the side wall of the cam 603. The other end of the auxiliary spring 604 is fixedly connected to the inner wall of the base 5. The cam 603 is fixedly connected to the bolt 602. The limiting post 605 is slidably arranged in the base 5. An inclined surface is formed at the bottom end of the limiting post 605. The inclined surface at the bottom end of the limiting post 605 is in contact with the cam 603. Two bolts 602 are symmetrically arranged with respect to the base 5. One ends of the two bolts 602 are aligned with the fixing block 601. A slot 6001 is formed at one end of the two bolts 602 close to the fixing block 601. The diameter of the slot 6001 is slightly larger than the diameter of the fixing block 601. Two limiting posts 605 are symmetrically arranged with respect to the base 5. One ends of the two limiting posts 605 far from the cam 603 are aligned with the limiting hole 402. A compression spring 17 is connected between the limiting post 605 and the base 5. The limiting post 605 and the base 5 form an elastic telescopic structure through the compression spring 17.

[0035] In this technical solution, as Figures 1-4 shown, by using the fixing block 601 and the bolt 602, when the bolt 602 is pressed, the fixing block 601 enters the slot 6001. When the bolt 602 is rotated, the engagement connection with the fixing block 601 is completed, reducing the operation difficulty and improving the work efficiency. At the same time, the bolt 602 will drive the cam 603 to rotate, so that the cam 603 squeezes the limiting post 605 to slide and insert into the slot 401 for secondary fastening, improving the connection stability and having strong practicability.

[0036] It adopts the technical solution as Figure 8 、 Figure 9 shown.

Press the pin 602 so that the pin 602 squeezes the auxiliary spring 604 to contract. At the same time, the fixing block 601 will enter the slot 6001. At this time, rotate the pin 602, and the pin 602 will drive the slot 6001 to rotate synchronously, so that the fixing block 601 engages with the slot 6001. Immediately release the pin 602, and the pin 602 will reset and move under the elastic force of the auxiliary spring 604, so as to closely adhere to the fixing block 601. When the pin 602 rotates, it will drive the cam 603 to rotate synchronously. The cam 603 will squeeze the limit post 605, so that the limit post 605 slides along the inner wall of the base 5 while squeezing the compression spring 17 to contract. At this time, the protruding end of the limit post 605 will extend into the slot 401 to perform secondary engagement between the base 5 and the fixing member 4, preventing the base 5 from falling off, and thus completing the rapid installation of the base 5.

[0038] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned Embodiment 1 and Embodiment 2. When performing maintenance, in case of an emergency, the door opening is slow and it affects the accident handling.

A slider 9 is slidably connected inside the rotating column 8. A moving ring 10 is fixedly connected to the side of the slider 9. A second clamping block 1001 is fixedly connected to the side of the moving ring 10. A sleeve 12 is fixedly connected to the end of the rotating column 8 away from the slider 9. A ejector rod 13 is slidably connected inside the sleeve 12. A chute 1201 is provided on the sleeve 12. A first threaded hole 1202 is provided inside the sleeve 12 below the chute 1201; A handle 14 is sleeved outside the sleeve 12. A circular groove 1401 is provided inside the handle 14. A movable rod 15 is movably connected to the middle of the circular groove 1401. Raised blocks 16 are fixedly arranged on the inner walls of the circular groove 1401 at the upper and lower ends of the movable rod 15. A through second threaded hole 1402 is provided inside the handle 14 above the raised block 16. A plurality of first clamping blocks 701 are arranged in a circumferential array with respect to the center point of the fixed ring 7. An inclined surface is provided on the side of the first clamping block 701. A first spring 901 is fixedly connected to the side wall of the slider 9. The end of the first spring 901 away from the slider 9 is fixedly connected to the rotating column 8. A plurality of second clamping blocks 1001 are arranged in a circumferential array with respect to the center point of the moving ring 10.

The first threaded hole 1202 on the sleeve 12; is aligned with the second threaded hole 1402. The raised block 16 is slidably connected to the chute 1201. The movable rod 15 is aligned with the ejector rod 13. The end of the ejector rod 13 away from the movable rod 15 is fixedly connected to the slider 9.

[0039] In this technical solution, as Figure 5 shown, by the arrangement of the first clamping block 701 and the second clamping block 1001, the second clamping block 1001 can be driven by the slider 9 to achieve one-way rotation. When rotating in the reverse direction, the first clamping block 701 will limit the second clamping block 1001, that is, rotation is locked. The operation is simple and the adaptability is strong.

[0040] It adopts the technical solution as Figure 6 and Figure 7 shown. Align the raised block 16 on the handle 14 with the chute 1201. Then push the handle 14, so that the handle 14 drives the raised block 16 to slide along the chute 1201. After the raised block 16 abuts against the chute 1201, at this time the first threaded hole 1202 is aligned with the second threaded hole 1402. Pass the bolt through the first threaded hole 1202 and the second threaded hole 1402 at the same time, thereby completing the installation of the handle 14. The structure is simple and the installation efficiency is high. Then rotate the handle 14. The handle 14 will drive the sleeve 12 to rotate, so that the sleeve 12 drives the rotating column 8 to rotate. The rotating column 8 will drive the locking member 11 to rotate, so that the locking member 11 abuts against the abutting block 3, thereby completing self-locking;

[0041] When rotating the rotating column 8, the rotating column 8 will drive the slider 9 to rotate, and the slider 9 drives the moving ring 10 to rotate, so that the second clamping block 1001 on the side of the moving ring 10 slides along the surface of the first clamping block 701. Since the first clamping block 701 is fixed, the second clamping block 1001 presses the moving ring 10, the moving ring 10 presses the slider 9, and the slider 9 slides along the inner wall of the rotating column 8 while pressing the first spring 901 to contract, thereby driving the locking member 11 to abut against the abutting block 3. Since the first clamping block 701 is fixed, when the handle 14 is rotated in the reverse direction, the second clamping block 1001 will be in close contact with the first clamping block 701 under the action of the elastic force of the first spring 901, so that the first clamping block 701 limits the second clamping block 1001, and then locks the handle 14 so that it can only rotate in one direction. When it is necessary to open the cabinet door 2, only need to press the movable rod 15, so that the movable rod 15 presses the ejector rod 13, and the ejector rod 13 will push the slider 9 to slide, so that the slider 9 drives the moving ring 10 to move, and the second clamping block 1001 can be separated from the first clamping block 701.
