Description

A kind of improved battery case of structure

Technical field

The utility model relates to battery case field technologies, refer in particular to a kind of improved battery case of structure.

Background technique

Battery case is mainly used for storing battery and power outward.Existing battery case is mainly in the form of rectangular, seperated buckle etc. Either to realize installation and up to waterproof effect in such a way that straight card plus bolt tighten, or it is round but use battery Or battery folders are mounted on inside, come in such a way that screw thread rotation tightens it is closed reach waterproof effect, the shortcomings that this structure, is: making It is easily broken off with buckle and causes product bad, accessory is more, and structure is complicated, and volume is big, and uses the method for screw tightening excessively general Logical no novelty, waterproof effect are also bad.

Utility model content

In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide a kind of structure and changes Into battery case, can effectively solve the problem that existing battery case accessory is more, structure is complicated, volume is big, waterproof effect is bad.

To achieve the above object, the utility model is using following technical solution:

A kind of improved battery case of structure, includes box body and lid；The box body has an appearance for being used for placing battery Chamber is set, which covers the opening of accommodating cavity, positive conductive part and negative conductive part is provided in lid and box body, the accommodating The cross section of chamber is circle, and the opening of accommodating cavity, which is extended, round bayonet part, which is sheathed on outside round clamping part simultaneously It is fixed with round clamping part rotary fastening.

Preferably, the circumferential lateral surface of the round clamping part is convexly equipped with multiple first arc buttons, multiple first arc button It is intervally arranged, accordingly, is provided with multiple second arc buttons in the lid, multiple second arc deduction of points is not with corresponding first Arc button is rotary shifted to be fastened.

Preferably, the lateral margin of the lid, which is extended, fixed ear, offers fixation hole in the fixed ear.

The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology Known to scheme:

This product is designed using circular configuration, does not use the accessories such as screw, buckle in the case where capable of installing multiple batteries, no The mode airtight waterproof tightened using screw thread, can make every batteries completed in the case where arrangement precise positioning and realize series connection and Parallel circuit, to realize newest better using effect.

For the structure feature and effect for more clearly illustrating the utility model, come with reference to the accompanying drawing with specific embodiment pair The utility model is described in detail.

Detailed description of the invention

Fig. 1 is that the decomposition diagram of the preferred embodiment of the utility model is intended to.

Description of drawing identification:

10, box body 11, accommodating cavity

12, round bayonet part 13, the first arc button

20, lid 21, fixed ear

30, battery.

Specific embodiment

It please refers to shown in Fig. 1, it to include box body 10 that show the specific structures of the preferred embodiment of the utility model And lid 20.

The box body 10 has an accommodating cavity 11 for being used for placing battery 30, and accommodating cavity 11 can place three sections and the above battery 30, to realize power supply, the appearance profile of box body 10 is cylindrical in class, which covers the opening of accommodating cavity 11,20 He of lid Positive conductive part (not shown) and negative conductive part (not shown), the cross section of the accommodating cavity 11 are provided in box body 10 For circle, the opening of accommodating cavity 11, which is extended, round bayonet part 12, the lid 20 be sheathed on round clamping part 12 it is outer and with Round 12 rotary fastening of clamping part is fixed.

The circumferential lateral surface of the circle clamping part 12 is convexly equipped with multiple first arc buttons 13, between multiple first arc button 13 Every arrangement, accordingly, be provided with multiple second arc button (not shown) in the lid 20, multiple second arc deduction of points not with Corresponding first arc button 13 is rotary shifted to be fastened.

And the lateral margin of the lid 20 is extended fixed ear 21, offers fixation hole (in figure not in the fixed ear 21 Show), to be fixedly mounted with outside.

The working principle that the present embodiment is described in detail is as follows:

It is when production, 11 Design Orientation of accommodating cavity on box body 10 is good, by the circuit design above lid 20 and lid 20 It is good, positive conductive part and negative conductive part are also had good positioning, then box body 10 and lid 20 are aligned, does small angle rotation, clamping It is closed to reach waterproof effect.In use, lid 20 is removed, battery 30 is placed in accommodating cavity 11, so that the positive and negative anodes of battery Conducting is contacted with positive conductive part and negative conductive part respectively, 30 positive and negative anodes of battery are anti-loaded when battery 30 is installed does not turn on electricity Road accomplishes to protect the effect of battery 30 then to cover lid 20 very well.

The design focal point of the utility model is: this product is designed using circular configuration, in the case where capable of installing multiple batteries Without using accessories such as screw, buckles, the mode airtight waterproof tightened without using screw thread can make every batteries in the case where arrangement It completes precise positioning and realizes series connection and parallel circuit, to realize newest better using effect.

Technical principle of the utility model has been described above with reference to specific embodiments.These descriptions are intended merely to explain this reality With novel principle, and it cannot be construed to the limitation to scope of protection of the utility model in any way.Based on the explanation herein, Those skilled in the art, which does not need to pay for creative labor, can associate with other specific implementation modes of this utility model, These modes are fallen within the protection scope of the utility model.
