Description

Low-voltage switch cabinet

Technical Field

The utility model belongs to the technical field of the electrical equipment technique and specifically relates to a low-voltage switchgear is related to.

Background

The existing low-voltage switch cabinet comprises a cabinet body, wherein a front door and a rear door are installed on the cabinet body. A plurality of vertical beams are installed on the inner side of the cabinet body and are made of angle iron and other materials, a plurality of cross beams are installed on the vertical beams through screw nut structures, a plurality of connecting holes are formed in each cross beam, and electrical equipment such as a low-voltage circuit breaker is installed on the connecting holes through the screw nut structures.

The above technical solution has the following disadvantages: 1. the position of the vertical beam is fixed and limited by the vertical beam, the position and the angle of the cross beam are relatively fixed, the flexibility of arranging electrical equipment such as a low-voltage circuit breaker and the like is poor, and the space utilization of the cabinet body is unreasonable; 2. traditional crossbeam needs an operating personnel to right the crossbeam when the dismouting, and another operating personnel comes dismouting screw nut, and work efficiency is low.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome above-mentioned conventional art's weak point, provide a low-voltage switchgear, increase the crossbeam and arrange the flexibility, improve crossbeam dismouting efficiency.

The purpose of the utility model is achieved through the following technical measures:

the utility model provides a low-voltage switch cabinet, includes the cabinet body, the internal two curb plates that have a plurality of jacks of installing of cabinet are equipped with the crossbeam that has a plurality of connecting holes between two curb plates, the sleeve is respectively installed to two tip of crossbeam, sliding connection has the first pin that can get into the jack in the sleeve, install the fixing device who is used for fixed first pin on the sleeve, each sliding connection of two tip of crossbeam has the movable block that can the up-and-down motion, threaded connection has the second pin that can get into another jack on the movable block.

Due to the adoption of the technical scheme, before the cross beam needs to be installed, the second pin is rotated to retreat; then, both ends of the beam are respectively held by both hands, and the first pin is poked by using the thumb to retreat.

When the cross beam needs to be installed, firstly, the cross beam is placed between two side plates, and two first pins are aligned to the jacks; then, using a thumb to poke the first pin to enable the first pin to enter the jack; and finally, operating the two movable blocks, aligning the two second pins with the jacks, and screwing the second pins and the fixing device.

When the cross beam needs to be disassembled, firstly, the second pin is rotated to enable the second pin to retreat and separate from the jack; then, two hands respectively hold two ends of the cross beam, and a thumb is used for poking the pull handle to enable the first pin to retreat and separate from the jack; and finally, taking out the cross beam.

The side surface of the first pin is connected with a pull handle, the side surface of the sleeve is provided with a strip-shaped sliding groove for the pull handle to penetrate, and one end, close to the side plate, of the sliding groove is communicated with a limiting groove which is perpendicular to the sliding groove.

Before the crossbeam needs to be installed, the pull handle is pulled by a thumb to control the first pin to rotate, and the pull handle is pulled after being separated from the limiting groove to enable the first pin to retreat. When the crossbeam needs to be installed, the pull handle is pulled by a thumb, and when the first pin enters the jack, the pull handle is pulled to control the first pin to rotate, so that the pull handle enters the limiting groove. When the crossbeam needs to be dismantled, the pull handle is pulled by the thumb to control the first pin to rotate. When the pull handle is separated from the limiting groove, the pull handle is pulled, so that the first pin retreats to be separated from the jack. The pull handle enters the limiting groove, so that the situation that the first pin retreats to separate from the jack to cause the cross beam to fall off when other parts are operated is avoided.

The fixing device comprises a bolt in threaded connection with the sleeve, and the end part of the bolt can abut against one end, far away from the side plate, of the first pin. The bolt is screwed up, and the bolt pushes forward first pin, makes first pin tip and jack bottom surface closely laminate, improves fixed effect.

The crossbeam is connected with the preceding baffle of vertical setting and the backplate of vertical setting, the movable block is located between preceding baffle and the backplate, set up the preceding through-hole that is the bar that holds the second pin and pass on the preceding baffle, set up the back through-hole that is the bar that holds the second pin and pass on the backplate. The movable block and the second pin can move up and down, and the second pin is convenient to align to the jack.

The thickness of the side plate at the edges of the front side and the rear side is smaller than that of the middle part of the side plate, and the edges of the side plate are connected with the side face of the cabinet body. The middle part of the side plate is thicker, which is beneficial to improving the strength of the side surface of the jack and improving the fixing effect.

The shape of first pin is cylindrical, the shape of second pin is cylindrical, the shape of jack cross-section is circular. The first pin and the second pin can conveniently go in and out of the jack.

The bottom surface periphery of the jack is obliquely arranged, correspondingly, the periphery of the end part of the first pin is obliquely arranged, and the periphery of the end part of the second pin is obliquely arranged. Make things convenient for first pin and second pin business turn over jack to for first pin and second pin provide radial thrust, improve fixed effect.

In conclusion, the side plates are provided with the plurality of jacks, so that the arrangement of the cross beam is more flexible; when the cross beam needs to be installed, two first pins are aligned to the jacks; use the thumb to stir first pin, make first pin get into the jack, with the crossbeam temporary erection on the curb plate, when operating other structures, need not operating personnel and right, single crossbeam dismouting can be accomplished, the dismouting is efficient.
