Description

Battery cover for preventing children from disassembling TECHNICAL FIELD

[0001] The present application belongs to the technical field of sighting devices, in particular to a battery cover for preventing children from disassembling. BACKGROUND

[0002] Most laser sighting devices use lithium batteries as power supply, and generally adopt a battery cover to block the button lithium battery in the battery compartment. The most common way is to connect the battery cover and the battery compartment by threads. This way is simple in process and convenient to disassemble and assemble, but its defects are also very prominent and obvious. That is, under proper rotating force, the battery cover can be easily opened and the button battery can be easily taken out. For children who can easily access the sighting device, it is very easy to unscrew the battery cover. Out of curiosity, children will disassemble the battery with bare hands. During the disassembly process, there is an inevitable risk of accidental injury to children. For this reason, people have developed an embedded buckle connection battery cover connection structure. However, under the premise of proper external force, this structure can also be opened by children with bare hands. The accidental injury to children caused by disassembling the battery cover with bare hands cannot be avoided. SUMMARY

[0003] The purpose of the present application is to provide a battery cover that is firmly connected and not easy to open with bare hands, so as to avoid accidental injury caused by opening the battery cover with bare hands.

[0005] A threaded connecting column with external threads is arranged on the inner side of the cover body and located in the inner circle of the circumferential side wall.

[0006] A tool insertion port is arranged on the outer side of the cover body.

[0007] As a further improvement, a recessed ring is arranged at the axial outer end and inner end of the circumferential outer side wall, and a protruding ring that can be buckled into the recessed ring is arranged on the abutting and surface of the circumferential side wall of the sliding sleeve.

[0008] As a further improvement, an inner recessed buckle is arranged at the axial outer end and inner end of the circumferential outer side wall, and a protrusion that can be buckled into the inner recessed buckle is arranged on the abutting and surface of the circumferential side wall of the sliding sleeve.

[0009] As a further improvement, an inner recessed buckle or an inner recessed ring is arranged on the axial center line of the circumferential outer side wall, and a clamping block that can be buckled into the inner recessed buckle or the inner recessed ring is arranged on the abutting and surface of the circumferential side wall of the sliding sleeve.

[0010] As a further improvement, the tool insertion opening is a slot or a cross.

[0011] As a further improvement, a plurality of vertical anti-skid edges are arranged on the outer circumferential side wall of the sliding sleeve.

[0012] The present application has the advantages of simple structure, convenient operation and maintenance, and good anti-disassembly and safety performance. BRIEF DESCRIPTION OF DRAWINGS
