[0015] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0016] Reference Figure 1-6 As shown, a battery compartment lock according to this embodiment includes: Casing 1; Rotating rod 2 is rotatably mounted in housing 1; Two connecting pieces 3 are provided, each with a connecting hole 33. The two ends of the rotating rod 2 are respectively inserted into the corresponding connecting holes 33 and form a rotational fit with the connecting piece 3. The housing 1 has slots 11 corresponding to the positions of each connecting piece 3, and each connecting piece 3 is inserted into the corresponding slot 11.

[0017] During installation, first, insert both ends of the rotating rod 2 into the connecting holes 33 of the two connecting pieces 3 respectively. The rotating rod 2 and the connecting pieces 3 form a rotational engagement, meaning the rotating rod 2 can rotate relative to the connecting pieces 3. Then, insert the two connecting pieces 3 into the corresponding slots 11 on the housing 1, thus completing the installation of the rotating rod 2 in the housing 1. The entire installation process requires no screws or other fasteners, nor any tools; it can be completed through simple plugging, significantly improving installation efficiency. Because the rotating rod 2 is installed through the plugging engagement of the connecting pieces 3 and the slots 11 rather than being pressed by a pressure plate, the problem of excessive rotational resistance or loosening of the rotating rod 2 due to improper pressing force is eliminated. This solves the problem in the prior art where the pressing force of the pressure plate is difficult to control, leading to loosening or inflexible rotation of the rotating rod 2.

[0018] In order to facilitate reliable positioning after the connecting piece 3 is inserted into the slot 11, in one optional scheme, the bottom of the slot 11 is provided with a positioning groove 131, and the connecting piece 3 is provided with a positioning part 31 at the position corresponding to the positioning groove 131, and the positioning groove 131 and the positioning part 31 are inserted and engaged.

[0019] The positioning groove 131 is a recess or through hole structure at the bottom of the slot 11, and the positioning part 31 is a structure at the corresponding position on the connecting piece 3. When the connecting piece 3 is pushed into the slot 11 along the insertion direction of the slot 11, the positioning part 31 moves together with the connecting piece 3. The positioning groove 131 and the positioning part 31 achieve limiting through a plug-in engagement, that is, the positioning part 31 is inserted into the positioning groove 131, thereby limiting the displacement of the connecting piece 3 and making the lock work more stably.

[0020] Furthermore, when the connecting piece 3 is inserted into the slot 11, the positioning part 31 at least partially enters the positioning groove 131.

[0021] The engagement between the positioning part 31 and the positioning groove 131 can be a partial insertion engagement, which only requires limiting the displacement and shaking of the connecting piece 3.

[0022] In one specific structure, a cover plate 4 is also included. The cover plate 4 is fixedly connected to the housing 1. A positioning groove 41 is provided on the cover plate 4. A positioning part 32 is provided on the connecting piece 3 at the position corresponding to the positioning groove 41. The positioning part 32 and the positioning groove 41 are inserted and engaged.

[0023] The cover plate 4 is fixedly connected to the housing 1 with screws. After the cover plate 4 is installed in place, the second positioning groove 41 on it engages with the second positioning part 32 on the connecting piece 3. At this time, the connecting piece 3 is simultaneously clamped from two directions by the first positioning groove 131 on the bottom and the second positioning groove 41 on the cover plate 4, forming a bidirectional positioning. This dual positioning significantly reduces the shaking of the connecting piece 3 in the slot 11, and the connecting piece 3 can remain stable even when the rotating rod 2 rotates frequently or the whole is subjected to external vibration.

[0024] For ease of processing, in one optional design, the positioning groove 131 is a through hole.

[0025] Specifically, the following methods can be selected for further optimization: the housing 1 includes a main body 12 and a base plate 13, the slot 11 is located on the main body 12, the slot 11 is a through structure, the base plate 13 is fixedly installed on the main body 12, and the positioning groove 131 is located on the base plate 13.

[0026] The shell 1 is divided into two parts: the main body 12 and the base plate 13. The slot 11 on the main body 12 has a through-hole structure, which facilitates molding. The base plate 13 is manufactured separately and fixedly installed on the main body 12. The positioning groove 131 is machined on the base plate 13, which can be machined on the base plate 13 alone before being assembled with the main body 12. This split structure reduces the manufacturing difficulty of the overall shell 1.

[0027] The design of the split shell 1 allows the three components, namely the main body 12, the base plate 13, and the cover plate 4, to be manufactured independently, reducing the complexity of each individual component.

[0028] In some options, the main body 12 is made of plastic, while the base plate 13 and cover plate 4 are made of metal.

[0029] The main body 12 is made of plastic, which can be molded in one piece through injection molding, resulting in low cost and high production capacity. The base plate 13 and cover plate 4 are made of metal, possessing high strength and rigidity. This provides stable structural support for the mating of positioning groove 131 and positioning groove 41 with their corresponding positioning parts, making the positioning grooves less prone to wear or deformation. The combination of the plastic main body 12 with the metal base plate 13 and cover plate 4 reduces overall cost while ensuring the structural strength and stability of key components, solving the problems of insufficient strength of the positioning groove when using plastic as a single piece or excessive cost when using metal as the entire piece.

[0030] In one specific structure, the positioning part 31 is a protrusion protruding outward from the connecting piece 3.

[0031] The positioning part 31 adopts a protruding structure that protrudes directly outward from the surface of the connecting piece 3, and can be a protrusion or flange integrally formed with the connecting piece 3. This structure is easy to process and can provide a simple and easy-to-form positioning part 31 implementation method.

[0032] In practical use, during installation, firstly, insert both ends of the rotating rod 2 into the connecting holes 33 of the two connecting pieces 3 respectively, forming a rotational fit between the rotating rod 2 and the connecting pieces 3; then, insert the two connecting pieces 3 into the corresponding slots 11 on the main body 12 of the housing 1 respectively, and after pushing them all the way down, the positioning part 31 on the connecting piece 3 enters the positioning groove 131 on the bottom plate 13 of the slot 11; fix the cover plate 4 to the housing 1, and the positioning groove 41 on the cover plate 4 engages with the positioning part 32 on the connecting piece 3. During operation, the rotating rod 2 rotates freely in the connecting holes 33 of the connecting piece 3 to lock or unlock. The connecting piece 3 remains stable due to the engagement of the positioning part 31 with the positioning groove 131 and the engagement of the positioning part 32 with the positioning groove 41, and will not loosen or shake due to the rotation of the rotating rod 2.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
