Description

Technical Field

[0001] This utility model belongs to the technical field of battery compartment locking devices, specifically relating to a battery compartment opening and closing device. Background Technology

[0002] When police officers are on duty on the road, they usually carry equipment such as roadblocks to stop vehicles. Some roadblocks need to be powered by portable batteries. Currently, the battery covers of existing portable batteries are directly installed by screws, so special tools such as screwdrivers are needed to open the battery covers. This is very inconvenient for officers on duty outdoors to carry and operate on site.

[0003] This case arose in response to the aforementioned technical issues. Summary of the Invention

[0004] The purpose of this invention is to provide a battery compartment opening and closing device that allows for easy opening and locking of the battery compartment cover by hand.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a battery compartment opening and closing device, which consists of a battery compartment cover and a locking device, characterized in that the locking device includes a quick-release screw that latches onto the battery compartment cover and a retaining spring that engages with the quick-release screw and the battery compartment cover, wherein the head end of the quick-release screw is provided with a movable and foldable lifting ring.

[0006] The quick-release screw head end surface is also provided with a slot, and the lifting ring is composed of a semi-circular ring. The lifting ring spans both sides of the quick-release screw head end and is installed on the two side walls of the head end through a rotating shaft.

[0007] Compared with the prior art, the beneficial effects of this utility model are: This utility model locks the battery compartment cover onto the battery compartment with a quick-release screw, and after a lifting ring is attached to the head end of the quick-release screw, the screw can be tightened and loosened by manually rotating the lifting ring. No additional screwdriver or other tools are required, and the battery compartment cover can be opened by hand. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] This invention addresses the shortcoming of existing battery boxes where the battery cover cannot be unscrewed by hand and requires a special tool.

[0020] Please see Figures 1 to 9 As shown in Embodiment 1, a battery compartment opening and closing device consists of a battery compartment cover 1 and a locking device. The locking device includes a quick-release screw 2 that is locked onto the battery compartment cover 1 and a retaining spring 3 that engages with the quick-release screw 2 and the battery compartment cover 1. The retaining spring 3 is specifically fitted onto the threaded end of the quick-release screw. The retaining spring 3 is used to prevent the quick-release screw 2 from falling out of the screw hole. The head end of the quick-release screw 2 is provided with a movable and foldable lifting ring 201. The lifting ring can be stood up and placed close to the battery compartment cover for easy manual rotation and force application.

[0021] like Figure 6 and Figure 7 As shown, the quick-release screw 2 is also provided with a slotted groove 202 on the head end surface (so that a screwdriver can be used to unscrew it if the lifting ring is damaged). The lifting ring 201 is a semi-circular ring. The lifting ring 201 spans the two sides of the head end of the quick-release screw 2 and is installed on the two side walls of the head end through a rotating shaft. The tail of the quick-release screw 2 is provided with an external threaded rod.

[0022] The specific installation method is as follows: the threaded rod of the quick-release screw 2 is inserted into the screw hole on the battery compartment cover. On the reverse side of the battery compartment cover, the retaining ring 3 is placed on the quick-release screw 2 to prevent the quick-release screw from falling out of the screw hole. After the battery compartment cover 1 is placed on the battery compartment, it is further locked by the quick-release screw 2. The lifting ring 201 is manually rotated to tighten the quick-release screw. Opening the battery compartment cover is also done by manually rotating the lifting ring to loosen the quick-release screw. It can be done by hand without any tools.

[0023] The main problem this invention solves is: to easily open the battery compartment cover by unscrewing the screws by hand.
