Description

Technical Field

[0001] The invention relates to the technical field of locks, in particular to an anti-pry lock for an electric meter box. Background Art

[0002] The existing meter box door lock has a simple lock core and lock tongue, which are not tightly matched and are easy to fall off and loose. In particular, the lock tongue used to fasten the meter box body is a very thin iron sheet, which is easy to deform, fall off and be pried open after locking. It has poor reliability and serious prying phenomenon, resulting in the meter box door being unable to be locked, posing serious electrical safety hazards and life safety hazards, as well as the phenomenon of private connection and electricity theft.

[0003] Most of the existing technologies are ordinary door locks, which are easy to be pried open. At the same time, the existing lock cores have poor protection capabilities. They are directly exposed to the outside world, which can easily lead to forced breaking by criminals and cause damage. Long-term exposure can easily cause the internal structure to be disturbed by the environment, causing the lock core to rust or become blocked, which is not conducive to normal use. At the same time, a single unlocking method is more easily cracked. Summary of the invention

[0004] The purpose of the present invention is to provide an anti-pry lock for an electric meter box, which solves the problems raised in the background technology.

[0005] An embodiment of the present application provides an anti-theft lock for an electricity meter box, comprising a device body, a rotating handle rotatably mounted on the device body, a lock box arranged next to the device body, a cover plate arranged on the device body, a rotating groove arranged next to the cover plate, and an operation panel arranged on the device body below the rotating groove.

[0006] In the present technical scheme, when it is necessary to open the main body of the device, the baffle is pulled. When the baffle moves, the password can be input, and at the same time, the second gear will be driven to move, so that under the action of the first rack, the second gear will be driven to rotate. When the second gear rotates, the rotating shaft will be driven to rotate, thereby driving the cleaning cloth installed thereon to rotate, so that the operation panel can be rotated to clean. At the same time, a storage slot (not shown in the figure) is provided on the main body of the device, and a spray bottle is placed in the storage slot to remove dust and fingerprints to prevent others from knowing the password. At this time, the electromagnet is powered off, and the card block is disengaged from the fixed slot on the card rod. At this time, the key body can be held by the holding part, and the opening block is inserted into the special-shaped slot to drive the rotating block to rotate, so that the cover plate can be opened, and then the key body can be inserted to open the lock body.

[0012] By adopting the above technical solution, the card rod is slidably mounted on the device body and is provided with a fixing groove. When the card rod needs to be fixed, the coil is energized so that the electromagnet becomes magnetic and the armature is squeezed upward, thereby driving the card block to move upward and get stuck in the fixing groove on the card rod. When the external force is removed, the card rod can be reset under the action of the spring so that the card rod can be opened.

[0013] Optionally, a sliding groove is provided on the device body next to the operation panel, a slider is slidably installed in the sliding groove, two groups of the slider and the sliding groove are provided and are symmetrically arranged on both sides of the operation panel, and a shielding plate is provided on the slider.

[0015] Optionally, a second gear is rotatably mounted on the shielding plate, a rotating shaft is fixedly mounted on the second gear, and a cleaning cloth is provided on the rotating shaft.

[0016] By adopting the above technical solution, when the second gear rotates, it will drive the rotating shaft to rotate, thereby driving the cleaning cloth installed thereon to rotate, so that the operation panel can be rotated to clean. At the same time, a storage slot (not shown in the figure) is provided on the device body, and a spray bottle is placed in the storage slot to remove dust and fingerprints to prevent others from knowing the password.

[0017] Optionally, a first rack is provided on the device body next to the operation panel, and the first rack and the second gear are meshed with each other.

[0018] By adopting the above technical solution, when the shielding plate moves, it will drive the second gear to move, and then drive the second gear to rotate under the action of the first rack.

[0019] Optionally, the device body is equipped with a key body, the key body is provided with a holding portion, the holding portion is provided with an opening block, and the opening block is adapted to the special-shaped groove.

[0020] By adopting the above technical solution, the key body can be held by the holding part, and the opening block can be inserted into the special-shaped groove to drive the rotating block to rotate, so as to open the cover plate, and then the key body can be inserted to open the lock body.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] 1. The present invention can protect the lock core by providing a cover plate to prevent it from being damaged from the outside by lawless elements, and at the same time can block rainwater to prevent rainwater from damaging the lock core;

[0023] 2. The present invention can shield the operation panel by setting a shielding plate, and can also be used with a spray bottle to clean dust and fingerprints on the operation panel, which is safer. BRIEF DESCRIPTION OF THE DRAWINGS
