Description

Technical Field

[0001] The utility model relates to the technical field of suspended low-voltage switch cabinets, in particular to a low-voltage switch cabinet for indoor use. Background Art

[0002] Low-voltage switch cabinets are divided into fixed and withdrawable types. Fixed switch cabinets can meet the requirements of reliably fixing various electrical components in a certain position in the cabinet. The cabinet is generally cubic in shape, such as screen type, box type, etc., and there are also prisms such as table type, etc. This type of cabinet has a single row or an array; the withdrawable switch cabinet is composed of a fixed cabinet and a removable device part equipped with switches and other main electrical components. The removable part should be easy to move and reliably positioned after being moved in, and drawers of the same type and specification can be reliably interchanged. The processing method of the cabinet part in the withdrawable type is basically similar to that of the fixed type.

[0003] Current indoor low-voltage switch cabinets include vertical and suspended types. When installing the suspended low-voltage switch cabinet, the placement base is first fixed to the wall by bolts, and then the switch cabinet is fixed to the placement base by bolts. When the switch cabinet is connected to the placement base, the installer needs to first move the switch cabinet as a whole to the placement base, and then use one hand to assist in limiting the switch cabinet, and use the other hand to use tools to fix the bolts to the bolt holes in sequence. Since the bolts are fixed with one hand and the bolts are small in size, during the rotation of the bolts, the angle deviation causes the bolts to pop out of the bolt holes, that is, fall to the ground, and the user needs to pick up the bolts again. This process is time-consuming and labor-intensive, affecting the connection efficiency of the switch cabinet to the placement base. Conversely, when disassembling the switch cabinet, the steps are relatively cumbersome. For this reason, a low-voltage switch cabinet for indoor use is provided. Utility Model Content

[0030] See also Figure 3The interior of the horizontal plate 403 is sleeved with a limiting column 4031, and the top and bottom ends of the limiting column 4031 are fixedly connected to the inner wall of the placement seat 1 by bolts.

[0031] See also Figure 2 The bottom end of the block 401 is fixed with a moving rod 4011 by bolts, and the moving rod 4011 is sleeved inside the spring 402, and the bottom end of the moving rod 4011 passes through the bottom of the placement seat 1, and the bottom end of the moving rod 4011 is fixed with a pull rod 4012 by bolts. The moving rod 4011 and the pull rod 4012 are used to release the engagement between the block 401 and the first slot 201, and the engagement between the column 407 and the second slot 202, thereby facilitating the rapid disassembly of the placement seat 1 and the switch cabinet body 2. It can be further explained that the movement of the pull rod 4012 drives the moving rod 4011 to move, and the movement of the moving rod 4011 drives the block 401 to move, and the block 401 moves downward and drives the column 407 and the protrusion on the outer wall of the column 407 to rotate through mechanical transmission. At this time, the block 401 is separated from the first slot 201, and the protrusion on the outer wall of the column 407 is separated from the rotating slot 2021, so that the placement seat 1 can be separated from the switch cabinet body 2.

[0032] Working principle: when in use, first place the switch cabinet body 2 on one end of the placement seat 1, then move the switch cabinet body 2 horizontally, and make the bottom end of the switch cabinet body 2 and one end of the card block 401 at the same horizontal height, then push the switch cabinet body 2, the switch cabinet body 2 moves toward the end close to the card block 401, and one end of the switch cabinet body 2 contacts one end of the card block 401. Since one end of the card block 401 is set in an inclined shape, one end of the switch cabinet body 2 squeezes the card block 401 to move downward, and the spring 402 is squeezed by force. When the card block 401 and the first card slot 201 are in the same vertical position, the spring 402 returns to its original state and drives the card block 401 to move, and the card block 401 is engaged in the first card slot 201, and the placement seat 1 is connected and fixed to the switch cabinet body 2;

[0033] Secondly, as the block 401 moves downward, it drives the horizontal plate 403 to move downward, the movement of the horizontal plate 403 drives the rack 404 to move downward, the movement of the rack 404 drives the first spur gear 405 to rotate counterclockwise, the counterclockwise rotation of the first spur gear 405 drives the second spur gear 406 to rotate clockwise, the rotation of the second spur gear 406 drives the clamping column 407 to rotate clockwise, and when the block 401 moves to the interval inside the placement seat 1, the clamping column 407 rotates ninety degrees. The protrusion on the outer wall of the clamping column 407 changes from a horizontal shape to a vertical shape, and in the process of horizontal movement of the switch cabinet body 2, the protrusion on the outer wall of the clamping column 407 passes through the second clamping groove 202 and enters the rotating clamping groove 2021. When the spring 402 returns to its original state, the clamping block 401 resets and drives the clamping column 407 to reset and rotate through mechanical transmission. The clamping column 407 rotates counterclockwise and drives the protrusion on the outer wall to rotate counterclockwise. At this time, the protrusion on the outer wall of the clamping column 407 is engaged with the inner wall of the rotating clamping groove 2021.

[0034] Afterwards, when disassembling the placement seat 1 and the switch cabinet body 2, the installer only needs to pull the pull rod 4012 downward, the movement of the pull rod 4012 drives the moving rod 4011 to move, the movement of the moving rod 4011 drives the clamping block 401 to move, the clamping block 401 moves downward and drives the clamping column 407 and the protrusion on the outer wall of the clamping column 407 to rotate through mechanical transmission, at this time, the clamping block 401 is separated from the first clamping groove 201, and the protrusion on the outer wall of the clamping column 407 is separated from the rotating clamping groove 2021, and the placement seat 1 can be separated from the switch cabinet body 2;

[0035] Finally, by setting the clamping block 401 and the first clamping slot 201, it is convenient to carry out the first stage of connection and fixation between the placement seat 1 and the switch cabinet body 2, and fix the bottom end of the switch cabinet body 2 to the placement seat 1. By setting the outer wall protrusion of the clamping column 407 and the rotating clamping slot 2021, it is convenient to carry out the second stage of connection and fixation between the placement seat 1 and the switch cabinet body 2, and fix one end of the switch cabinet body 2 to the placement seat 1. Compared with the traditional method of fixing with bolts, the connection efficiency of the placement seat 1 and the switch cabinet body 2 is improved. At the same time, the locking part of the placement seat 1 and the switch cabinet body 2 can be unlocked by pulling the pull rod 4012 downward, which is convenient for the quick disassembly of the placement seat 1 and the switch cabinet body 2.
