Abstract

The utility model relates to the field of energy and can be used in low-voltage package devices and switchboards of control stations. The purpose of the proposed utility model is to create a blocking mechanism for a sliding module of a low-voltage package device, which can be used without changing its design features regardless of the size and configuration of the circuit breaker shaft. The problem is solved due to the fact that the locking mechanism of the sliding module of the low-voltage complete device a shaft retainer comprises a circuit breaker driven by a rotary handle control circuit breaker, which is mounted on the front panel extension module low-voltage devices, consisting of two identical strips with different-sized grooves on both sides of each strap are connected together by means of screws.

Description

The utility model relates to the field of energy and can be used in low-voltage complete devices and switchboards of control stations.

Known low-voltage complete device for input, distribution of energy and control (see patent No. 123588 from 06.25.212) with a protection mechanism for a retractable modular unit containing a base with a guide attached to it, made in the form of a bracket, a valve fixed in the guide and moving in vertical direction through the holes made in the base and the upper part of the guide, a lever, one end of which is connected against the stop using a finger with a bolt, and the other end with a screw with a sleeve, on which clamping screw fixed rotary knob drive. Inside the guide there is a spring and a washer. The disadvantage of this design is that when changing the size or configuration of the drive of the rotary knob, you must change the sleeve or use an adapter.

The objective of the proposed utility model is to create a locking mechanism for a sliding module of a low-voltage complete device, which can be used without changing its design features regardless of the size and configuration of the circuit breaker shaft.

The problem is solved due to the fact that the locking mechanism of the sliding module of the low-voltage complete device includes a shaft lock for the circuit breaker, which is driven by the rotary handle of the circuit breaker, which is installed on the front panel of the sliding module of the low-voltage complete device, consisting of two identical strips with different-sized grooves with both sides of each bar, interconnected by screws.

The technical result is to increase the operational manufacturability of a low-voltage complete device.

The utility model is illustrated in the drawing, which shows the locking mechanism of the sliding module of the low-voltage complete device.

The locking mechanism of the sliding module of the low-voltage complete device consists of a bracket 1, mounted on the base of the sliding module of the low-voltage complete device, a valve 2 with a groove for the travel stop 3 and holes for adjusting the stroke of the circuit breaker (not shown), which moves vertically through the holes made in bracket 1 and at the base of the pull-out module of the low-voltage package device. A corner 4 is fixed on the valve 2, in the groove of which an axis 5 is mounted with the possibility of rotation, on which a lever 6 is mounted with a lock 7 of the circuit breaker shaft fixed to it. The shaft of the circuit breaker is driven by a rotary control handle of a circuit breaker (not shown) mounted on the front panel of the pull-out module of the low-voltage package device. The latch 7 of the shaft of the circuit breaker consists of two identical strips 8 with different grooves on both sides of each plank and interconnected by two screws 9. The lever 6 is connected to one of the planks by two stops 10 that provide free movement of the lever 6 along the oval hole in mute, which allows you to compensate for the variation in the angle of rotation of the circuit breaker. In turn, the grooves on the slats 8 provide the alignment of the rotary control handle of the circuit breaker, regardless of its size and configuration.

The device operates as follows.

When the circuit breaker is turned on by the rotary control handle of the circuit breaker, mounted on the front panel of the drawer module of the low-voltage package device and connected to the circuit breaker through a shaft (not shown), the shaft rotates by a predetermined angle. Through the shaft lock 7 by the circuit breaker and the axis 5 of the lever 6, an impact is made on the corner 4 with a groove, which ensures that the valve 2 moves vertically down into the groove of the base of the drawer module, blocking the possibility of sliding the drawer module of the low-voltage complete device when the circuit breaker is turned on. When the circuit breaker is turned off, the valve 2 is released from the base groove of the drawer module of the low-voltage package device, making it possible to extend the drawer module of the low-voltage package device when the circuit breaker is turned off.

Claims (1)

The locking mechanism of the pull-out module of the low-voltage complete device, characterized in that it contains a shaft lock for the circuit breaker, which is driven by the rotary handle of the circuit breaker, which is mounted on the front panel of the draw-out module of the low-voltage complete, consisting of two identical strips with equal grooves on both sides of each straps interconnected by screws.
