Detailed Description

The technical solutions of the present utility model will be clearly and completely described in connection with the embodiments, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1-4, which are schematic structural views of an electric meter box convenient for maintenance according to a preferred embodiment of the present utility model, the electric meter box comprises a casing 10, a maintenance window 20 opened by overturning is provided at one side of the casing 10, a lock opening 201 is opened at the upper portion of the maintenance window 20 towards the side of the casing 10, a lock rod 202 is integrally formed in the lock opening 201, a locking structure 30 is provided on the casing 10, the locking structure 30 corresponds to the lock opening 201 of the maintenance window 20, the locking structure 30 comprises a lock body 301 and a spring 302, one end of the spring 302 is welded to the casing 10, the other end is welded to the lock body 301, a chute 3011 for sliding in the lock rod 202 is provided at two sides of the lock body 301, a counter bore 3012 is provided at one side of the chute 3011 towards the spring 302, the lock body 301 is driven by pressing the maintenance window 20 inwards, so that the lock body 301 is driven to swing by the lock body 301, and the counter bore 3012 of the lock body 301 enters the chute 3011 due to a clearance allowance between the lock rod 202 and the counter bore 3012 of the lock body 301, so that the lock body 301 gets out of the chute 3011, and the other end is welded to the casing 301, and the operator can open for maintenance window conveniently.

In this embodiment, the depth of the counter bore 3012 is greater than the depth of the chute 3011, the diameter of the lock rod 202 is smaller than the diameter of the counter bore 3012, and a clearance allowance is formed, the depth of the counter bore 3012 is greater than the depth of the chute 3011, so that the access window 20 is prevented from being accidentally opened, and the setting of the clearance allowance enables the lock rod 202 to withdraw from the counter bore 3012, so that the access window 20 is opened.
