Problems solved by technology

[0002] The vacuum cleaner battery pack is specifically a plastic shell installed on the vacuum cleaner. The battery installed inside provides power support for the vacuum cleaner to work. The battery pack is generally equipped with a lock structure for fixing the battery after it is installed; the traditional battery pack The lock structure is generally in the form of a single buckle. A slot that matches the buckle is provided on the battery pack shell, and the locking function is realized by setting the inside of the slot through the buckle. This structure needs to be manually broken when the buckle is unlocked. When opening the buckle, if the locking force of the buckle is strong, it is difficult for the user to break open to unlock it. At the same time, the plastic buckle will wear and tear when it is moved for a long time, which will reduce the degree of engagement between the buckle and the slot. Causing the locking structure to loosen, etc.

[0029] Please combine image 3 , Figure 4 as well as Figure 5 , a rotary locking structure for a vacuum cleaner battery pack, comprising a battery pack housing 1, a locking mechanism is provided inside the battery pack housing 1, and the locking mechanism includes a buckle 2 and an assembly with the buckle 2 The matching rotating rod 3, the buckle 2 is fixed on the rotating rod 3; the rotating rod 3 is rotatably arranged inside the battery pack housing 1; the bottom of the battery pack housing 1 is provided with The card slot 4 corresponding to the buckle 2, the battery pack housing 1 is provided with a switch structure acting on the rotating rod 3; the rotating rod 3 is provided with two left-right symmetrical protrusions 7 , the side of the bump 7 is a first slope 8; the switch structure includes two left and right buttons 9 correspondingly arranged, the head of the button 9 is provided with a pressing block 10, and the surface of the pressing block 10 is the same as Th...

Embodiment approach

[0032] The fastening part of the buckle 2 is provided with an arc surface; the arc surface can increase the locking force of the entire buckle structure, and due to the rotating structure of the buckle 2, there is no need to worry about the buckle 2 and the slot 4 being stuck together. The situation that it cannot be separated after connection; at the same time, when the bottom shell of the battery pack is in contact with the buckle 2, due to the design of the arc surface, the contact between the two can be made smoother.

[0033] The lock mechanism is specifically an integrated structure composed of the rotating rod 3 and the buckle 2; the rotating rod 3 and the buckle 2 are formed by mold injection molding into an integrated structure, which does not require subsequent assembly and can be used as a battery The installation of the bag improves the portability, and at the same time, the one-piece structure can prevent the buckle 2 from loosening.

Abstract

A rotary lock catch structure of a dust collector battery pack comprises a battery pack shell, a lock catch mechanism is arranged in the battery pack shell, the lock catch mechanism comprises a buckleand a rotating rod matched with the buckle, the buckle is fixed to the rotating rod, and the rotating rod is rotatably arranged in the battery pack shell; a clamping groove corresponding to the buckle is formed in the battery pack shell, and meanwhile, a switch structure acting on the rotating rod is arranged on the battery pack shell; according to the battery pack lock catch structure designed by the scheme, the rotating rod is matched with the buckle; the buckle is rotated around the axis of the rotating rod, flexible switching between unlocking and non-unlocking of the buckle is achieved,the rotary lock catch structure is different from a traditional lock catch structure, and the buckle is made to move between the clamping position and the loosening position in a rotating mode throughingenious structural design.
