Slot A is located on the inner side of the bottom end of the upper housing, slot B is located on the inner side of the top end of the lower housing, and slot C is located on the side of the lower housing. Slot C and slot B are in communication. The block component is located inside slot A, slot B, and slot C. The elastic component is located at the connection between the top end of slot A and the top end of the block component.

[0007] Preferably, the block assembly consists of block A and block B, with block B fixed to the bottom end of block A.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a battery compartment housing for an electric tool, including an upper housing 1 disposed on the top of the lower housing 2, a locking member disposed on the top of the upper housing 1, and locking mechanisms 3 disposed on both sides of the connection between the upper housing 1 and the lower housing 2;

[0025] The locking mechanism 3 consists of a spring component 31, a locking groove A32, a locking groove B33, a block component 34, and a locking groove C35. Locking groove A32 is located on the inner bottom of the upper housing 1, locking groove B33 is located on the inner top of the lower housing 2, and locking groove C35 is located on the side of the lower housing 2. Locking groove C35 and locking groove B33 are interconnected. The block component 34 is located inside locking groove A32, locking groove B33, and locking groove C35. The spring component 31 is located at the connection between the top of locking groove A32 and the top of block component 34. This locking mechanism 3 improves upon the previous method of installing the upper housing 1 and lower housing 2 of the power tool battery compartment using a locking mechanism. During repeated disassembly and reassembly over long-term use, this locking mechanism could loosen, affecting installation stability. Qualitative impact is achieved by adding a locking mechanism 3 to the original installation of the upper housing 1 and the lower housing 2. During the installation process, the locking mechanism 3 simultaneously limits the movement of the battery compartment housing of the power tool while ensuring ease of installation. This ensures the stability of the power tool under repeated disassembly and assembly during long-term use. The block assembly 34 consists of block A341 and block B342. Block B342 is fixed to the bottom end of block A341. The fixing of block B342 to the bottom end of block A341 increases the ease of locking block B342. The cross-sectional dimension of the end of block B342 is smaller than the cross-sectional dimension of the bottom end of block A341. The side cross-section of block A341 has an L-shaped structure. The bottom mounting surface of the upper housing 1 and the top mounting surface of the lower housing 2 are in a locking state.

[0026] In this embodiment, preferably, the elastic component 31 is composed of a torsion spring 311, a crossbar 312, and a groove component 313. The groove component 313 is composed of a limiting groove 3131 and a through hole 3132. The through hole 3132 is opened on the inner side of the block A341, and the limiting groove 3131 is opened in the middle of the through hole 3132. The crossbar 312 passes through the inner side of the through hole 3132 and the limiting groove 3131. The two ends of the crossbar 312 are fixed to the inner walls of the slot A32 respectively. The torsion spring 311 is sleeved on the surface of the crossbar 312. The top of the block component 34 is movably connected to the slot A32 through the elastic component 31. The two ends of the torsion spring 311 are fixed to the inner walls of the limiting groove 3131 respectively. The crossbar 312 has a cylindrical structure, and the length of the crossbar 312 is the same as the length of the slot A32.

[0027] Example 2

[0028] Please see Figures 1 to 6 This utility model provides a technical solution: a battery compartment housing for an electric tool, including an upper housing 1 disposed on the top of the lower housing 2, a locking member disposed on the top of the upper housing 1, and locking mechanisms 3 disposed on both sides of the connection between the upper housing 1 and the lower housing 2;

[0029] The locking mechanism 3 consists of an elastic component 31, a locking groove A32, a locking groove B33, a block component 34, and a locking groove C35. Locking groove A32 is located inside the bottom end of the upper housing 1, locking groove B33 is located inside the top end of the lower housing 2, and locking groove C35 is located on the side of the lower housing 2. Locking groove C35 and locking groove B33 are interconnected. The block component 34 is located inside locking groove A32, locking groove B33, and locking groove C35. The elastic component 31 is located at the top end of locking groove A32. At the top connection of the block assembly 34, a designed locking mechanism 3 improves the original installation method of the upper shell 1 and lower shell 2 of the power tool battery compartment. Previously, these shells were installed using a locking mechanism, which could loosen during repeated disassembly and reassembly over long-term use, affecting installation stability. By adding a locking mechanism 3 to the original installation of the upper shell 1 and lower shell 2, the locking mechanism 3 simultaneously limits the movement of the shells during installation, ensuring ease of installation while reinforcing the installation of the power tool battery compartment and ensuring stability under repeated disassembly and reassembly during long-term use. The block assembly 34 consists of blocks A341 and B342. Block B342 is fixed to the bottom end of block A341. The cross-sectional dimension of the end of block B342 is smaller than that of the bottom end of block A341. The side cross-section of block A341 is L-shaped. The bottom end of the upper shell 1 is... The mounting surface and the top mounting surface of the lower housing 2 are in a snap-fit ​​state. An anti-slip component is provided on the inner side of the slot C35. The anti-slip component consists of a mounting groove 351 and a silicone seat 352. The mounting groove 351 is opened on the inner wall of the slot C35, and the silicone seat 352 is fixed to the inner side of the mounting groove 351. When the bottom end of the block component 34 is snapped into the inner side of the slot C35, the block B342 squeezes the inner wall of the silicone seat 352, so that the blocks A341 and B342 are snapped in place and further reinforced.

[0030] The working principle and usage process of this utility model are as follows: When it is necessary to install the upper shell 1 and lower shell 2 of the power tool battery compartment, the two are fixed by a snap-fit ​​and limiting method. By pushing the block components 34 set at the bottom of both sides of the upper shell 1 to the rear, the block components 34 are flipped backward with the through crossbar 312 as the center, and the torsion spring 311 is in a torsional state. Then, the mounting surfaces of the upper shell 1 and the lower shell 2 are put into contact, and the block components 34 are released simultaneously. Under the torsion of the torsion spring 311, they rebound, so that the blocks A341 and B342 are in a snap-fit ​​state with the slots A32 and C35, so that the upper shell 1 and the lower shell 2 are limited, thereby completing the snap-fit ​​and limiting installation of the upper shell 1 and the lower shell 2.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
