Abstract

A battery-cover latch structure having a shell and a battery-cover is provided for a tool. The shell has a battery slot, a longitudinal slot and a plurality of lateral slots arranged in a same direction and on opposite sides of the battery slot. The battery-cover is detachably connected to the shell and covers the battery slot. The battery-cover has a pullable portion formed on a side, a longitudinal-clamping block engaged with the longitudinal slot and a plurality of lateral-clamping blocks extending in a same direction and engaged with the lateral slots. The longitudinal-clamping block extends downward from a bottom of the pullable portion and forms a notch portion with the pullable portion. When the tool abuts the notch portion and pushes the pullable portion, the longitudinal-clamping block detaches from the longitudinal slot to make the lateral-clamping blocks detach from the lateral slots.

Description

Battery cover lock structure

The present invention relates to a battery cover structure, and in particular to a battery cover latch structure.

Generally, the contents of batteries contain toxic substances. When the battery is damaged due to long-term use or external intervention, the battery contents will flow out. Therefore, in order to prevent young children from accidentally ingesting such toxic substances, the best way is to prevent young children from accessing the battery.

Therefore, some electronic devices that are easy for children to access usually use screws to fix the battery cover. The battery cover can be opened by loosening the screws, thereby preventing children from easily accessing the battery.

However, the above-mentioned fixing of the battery cover requires additional screws, and the screws will be worn out after being screwed in and removed many times, making the screws easy to fall off and be swallowed by unsuspecting children. Obviously, its safety is not good.

In view of this, the inventor has devoted himself to research on the above-mentioned existing technology and cooperated with the application of academic theory to try his best to solve the above-mentioned problems, which has become the development goal of the inventor.

The present invention provides a battery cover locking structure, which utilizes the fact that the battery cover requires the assistance of additional tools to be detached from the casing, so that the battery cover locking structure is difficult to disassemble easily.

In an embodiment of the present invention, the present invention provides a battery cover locking structure for a tool. The battery cover locking structure includes: a housing provided with a battery slot, a longitudinal locking groove, and a battery cover disposed in the battery slot. A plurality of transverse latching grooves are opened on opposite sides and in the same direction; and a battery cover is removably connected to the housing and covers the battery slot. The battery cover has a pullable portion and a latching portion formed on the side. A longitudinal clamping block connected to the longitudinal clamping groove and a plurality of transverse clamping blocks extending in the same direction and engaging in the plurality of transverse clamping grooves. The longitudinal clamping block extends downward from the bottom of the pullable part and is connected with the The pullable parts jointly form a notch part; wherein, when the tool resists the notch part and pushes the pullable part, the longitudinal retaining block will be driven away from the longitudinal retaining groove, so that the plurality of transverse The clamping block can slide out of the plurality of transverse clamping grooves.

Based on the above, when the battery cover is assembled into the casing, the longitudinal latching blocks are engaged and positioned in the longitudinal latching grooves, and the plurality of lateral latching blocks are engaged and positioned in the plurality of lateral latching grooves, so that the battery cover is not easily removed from the casing. disassembly to prevent young children from coming into contact with the battery housed between the battery cover and the casing, so that the battery cover locking structure has excellent locking ability and can improve the safety of use.

Based on the above, when the battery cover needs to be removed from the casing, the user can use a tool to resist the notch and push up the pullable portion, and drive the longitudinal holding block to disengage from the longitudinal latching groove, so that the battery cover can be relative to the casing. The body slides laterally, allowing the plurality of horizontal blocking blocks to slide out of the plurality of horizontal blocking grooves, so that the battery cover can be separated from the casing, so that the battery cover locking structure is not easy to disassemble.
