AI Technical Summary
The existing low-voltage metering box circuit breaker mounting brackets are inconvenient to adjust, have low adjustment efficiency, and poor fixing stability, resulting in low circuit breaker installation efficiency and affecting the efficiency of emergency repair work.
The circuit breaker mounting bracket adopts a combination structure of fixed bracket and sliding bracket. Through the matching setting of locking rod and locking groove, the height of the circuit breaker mounting bracket can be quickly adjusted and stably fixed. The sliding bracket can be unlocked and locked by the forward and backward movement of the locking rod, and the return spring can be used to improve the convenience of operation.
It achieves stable and adjustable height of the circuit breaker mounting bracket, adapts to different specifications of circuit breakers, is easy to operate, has high adjustment efficiency, ensures stable installation of circuit breakers, and improves installation efficiency.

Abstract
Claims
1. A low pressure meter box circuit breaker mounting bracket comprising a fixed bracket and a sliding bracket slidably mounted with the fixed bracket, characterized in that: The fixed bracket is a frame structure, including a base plate connected to the metering box and at least two support plates extending longitudinally perpendicular to the base plate. At least one support plate is provided with a longitudinal groove, and locking grooves perpendicular to the longitudinal groove are provided at intervals on the longitudinal groove. The sliding bracket is a frame structure that is adapted to the shape of the fixed bracket and is slidably inserted. The sliding bracket includes a top panel and a side panel for installing the circuit breaker. At least one side panel is provided with a locking rod adapted to the longitudinal groove and locking groove on the support plate of the fixed bracket.
2. The low pressure meter box circuit breaker mounting bracket of claim 1, wherein: The locking rod includes a locking tongue that engages with the locking groove of the fixed bracket in the axial direction, and a pressing part that slides with the longitudinal groove. The locking rod is locked or unlocked by moving it forward or backward.
3. The low pressure meter box circuit breaker mounting bracket of claim 2, wherein: The support plate with a longitudinal groove has a longitudinal groove on the side near the sliding bracket. The size of the latch in the left-right direction is smaller than the size of the groove in the left-right direction, so that when the latch is pushed into the groove, the longitudinal groove forms a clearance space for the latch to move in the longitudinal direction.
4. The low pressure meter box circuit breaker mounting bracket of claim 2, wherein: The sliding bracket is provided with clearance space to avoid the bolt moving in the left and right directions.
5. The low pressure meter box circuit breaker mounting bracket of claim 4, wherein: The sliding bracket has a sliding bracket support plate that is in close contact with the support plate of the fixed bracket, and the sliding bracket support plate is provided with a clearance groove for avoiding the locking tongue.
6. The low pressure meter box circuit breaker mounting bracket of any one of claims 1 to 5, wherein: A guide rod is fixed inside the frame structure of the sliding bracket. The guide rod is perpendicular to the side plate with the locking rod. A pressure plate is fitted on the guide rod. A return spring is fitted on the guide rod between the pressure plate and the vertical plate on the opposite side of the sliding bracket. The other side of the pressure plate is connected to the locking rod.
7. The low pressure meter box circuit breaker mounting bracket of any one of claims 1 to 5, wherein: The top of the sliding bracket is provided with threaded holes for mounting circuit breakers or circuit breaker mounting rails.
8. The low pressure meter box circuit breaker mounting bracket of any one of claims 1 to 5, wherein: The bottom of the fixed bracket is provided with vertically extending screws for connecting to the metering box.
9. The low pressure meter box circuit breaker mounting bracket of any one of claims 1 to 5, wherein: The fixed bracket has two parallel supporting plates, forming an installation space between the two supporting plates for installing two sliding brackets. Each supporting plate is used to cooperate with a sliding bracket through a locking rod and a locking tongue. A partition is also provided in the middle between the two supporting plates to separate the two sliding brackets. The plate surface of the partition opposite to each supporting plate and the plate surface of each supporting plate opposite to the partition are used to form the slide rail of the sliding bracket.
