Description

Technical Field

[0001] The utility model relates to the technical field of low - voltage switch cabinet locking, in particular to an interlocking mechanism for a low - voltage switch cabinet. Background Technique

[0002] A low - voltage switch cabinet is a power distribution device applicable to low - voltage power distribution systems such as power plants, petroleum, chemical industry, metallurgy, textile, high - rise buildings, etc. The low - voltage switch cabinet usually includes a cabinet body, a plurality of drawer units arranged on the cabinet body, a circuit breaker and other electrical components arranged in the drawer units, and an operating shaft connected to the circuit breaker. By swinging the operating shaft, the opening and closing of the circuit breaker can be realized, so as to realize the switching between the working state and the maintenance state of the switch cabinet.

[0003] There are certain defects in the existing low - voltage switch cabinets during use. The drawers in the switch cabinet need to be fixed to the cabinet body through a fixing device, but the accuracy and strength requirements of the fixing device are relatively high, and the existing fixing devices are prone to jamming or jamming during actual use, resulting in the drawers of the switch cabinet being unable to be pulled out normally. Moreover, there is no anti - detachment mechanism during the pulling process, and the drawer is prone to directly fall off the cabinet body during the pulling process, resulting in damage to the components in the drawer and unnecessary losses. For this reason, we propose an interlocking mechanism for a low - voltage switch cabinet. Content of the Utility Model

[0030] An installation groove is formed in the drawer body 2. A disc is rotatably connected in the installation groove. The first knob 7 passes through the drawer body 2 and is fixedly connected with the disc. Pin shafts are symmetrically installed on the disc. The pin shafts are movably connected with the movable rods 201. The movable rods 201 are movably connected with the linkage rods 202. The linkage rods 202 are fixedly connected with the telescopic rods 205. When it is necessary to pull out the drawer body 2, the first knob 7 is rotated. The rotation of the first knob 7 drives the rotation of the disc. While the disc rotates, it drives the movable rod 201 to move. While the movable rod 201 moves, the telescopic rod 205 is contracted by using the linkage rod 202.

[0031] The outer sides of the telescopic rods 205 are fixedly connected to the locking rods 204. Circular grooves are provided at both ends of the drawer body 2. The locking rods 204 are slidably connected to the circular grooves. A locking spring 203 is sleeved on the telescopic rods 205. When the telescopic rods 205 contract, the locking spring 203 is driven to contract, and then the locking rods 204 are driven to contract inward, starting to move the drawer body 2. Then, the first knob 7 is released, and the locking rods 204 are inserted into the positioning grooves. At this time, the drawer body can be conveniently pulled out of the cabinet body. Through the arrangement of the locking rods 204, the separation of the locking rods 204 from the cabinet body 1 can be effectively prevented.

[0032] Limit grooves are symmetrically provided at the lower ends of the slots 101. Threaded holes are evenly provided in the limit grooves.

By setting the gear transmission mechanism, it is possible to prevent the staff from accidentally touching the lever to open the cabinet door 6, thus facilitating use. After maintenance is completed, close the cabinet door 6, and then turn the second knob 9 in the reverse direction to insert the insertion rod 14 into the jack.

[0036] The working principle of an interlocking mechanism for a low-voltage switch cabinet provided by the present utility model is as follows: When it is necessary to draw out the drawer body 2, turn the first knob 7. The turning of the first knob 7 drives the rotation of the disc. While the disc rotates, it drives the movement of the movable rod 201. While the movable rod 201 moves, the telescopic rod 205 is contracted by using the linkage rod 202. While the telescopic rod 205 contracts, it drives the locking spring 203 to contract, and further drives the locking rod 204 to contract inward. Then start to move the drawer body 2, and then release the first knob 7. The locking rod 204 is inserted into the positioning groove. At this time, the drawer body can be conveniently pulled out from the cabinet body, which can effectively prevent the locking rod 204 from separating from the cabinet body 1.

At this time, the drawer body 2 can be conveniently disassembled from the cabinet body 1. The operation is simple and convenient. Move the lever 17 to the left. The movement of the lever 17 drives the telescopic spring 11 and the adjusting rod to move together. Turn the second knob 9. The turning of the second knob 9 drives the movement of the rack 15. The movement of the rack 15 causes the insertion rod 14 to move upward. By setting the gear transmission mechanism, it is possible to prevent the staff from accidentally touching the lever to open the cabinet door 6, thus facilitating use. After maintenance is completed, close the cabinet door 6, and then turn the second knob 9 in the reverse direction to insert the insertion rod 14 into the jack.
