Description

The battery latching device

Technical field

The utility model relates to a kind of battery latching device that is applied on the mobile communication equipments such as intercom.

Background technology

Mobile communication equipments such as intercom have been widely used in numerous areas, because of it needs regular mobile operating characteristic, so its product quality and durability are had higher requirement.

Mobile communication equipments such as intercom mainly are made up of main frame and battery two large divisions usually, are realized the function of communication to the main frame supply power by battery.In use, on the one hand because battery need often unload charging or change, thus being connected between battery and main frame must be movable; On the other hand,, avoid interrupting beyond the communication being connected and must having certain steadiness between battery and main frame for guaranteeing reliable connection the between battery and main frame.

The battery latching device that mobile communication equipments such as existing intercom generally adopt is as described below: it comprises to push away to buckle and push away buckles spring, push away button and push away the top that the button spring is arranged on main frame, battery and main frame snap fit are that the battery lower end directly is connected on the main frame, and the battery upper end is connected to the battery active card on the main frame by pushing away the mode of buckling down crimping.Upwards push away button, battery just can take off battery after upspringing naturally under the elastic force effect of battery connector shell fragment.The shortcoming of this mechanism is: it is bigger to take battery space, contradicts with the market demand that requires day by day to increase battery capacity; Simultaneously, it has limited the installation site of belt clamp, and belt clamp can only be installed on the battery, and can not be installed on the main frame.This all will bring bigger influence to the design and use of entire product.

Summary of the invention

The purpose of this utility model is the problems referred to above of existing at existing battery latching device, and a kind of reliable connection that not only can satisfy between battery and main frame is provided, and also can open the battery latching device of battery easily.

The purpose of this utility model be achieved in that the utility model comprise the screens that is located at the battery top and battery lower end button bit, be located at the main frame top corresponding with the battery screens draw-in groove, the battery that is located at the main frame bottom push away buckle, two battery grabs and two elastomers, described two battery grabs are positioned at the both sides that battery pushes away to buckle, described two elastomers are positioned at the outside of two battery grabs with preloading condition, battery grab pushes away with battery and buckles clamping mutually, and battery pushes away to be buckled to descend to move to make two battery grabs and inwardly close up or outwards open; The screens at described battery top is inserted in the draw-in groove at main frame top, and the button bit of battery lower end and two battery grabs are interlockingly connected.

Technique effect of the present utility model is: the utility model battery in use pushes away by battery and buckles above crimping mode active card down and be connected to and realize its locking on the main frame, so only needing downward promotion battery to push away buckles, driving two battery grabs outwards opens, the realization battery grab separates with battery lower end button bit, can easily battery be taken off from main frame; Unclamp battery and push away and buckle, battery grab inwardly rotates under elastomeric elastic force effect and closes up, and can be interlockingly connected with battery lower end button bit under this state, realizes being connected of battery and main frame, promotes battery simultaneously and pushes away to buckle upwards and reset.Present embodiment reliably is connected under the prerequisite between battery and main frame guaranteeing, has simplified design, has made things convenient for operation.

Embodiment

In order to explain technical problem to be solved in the utility model, technical scheme and beneficial effect thereof clearlyer,, it is further described in detail below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only is used to explain the utility model, and be not used in qualification the utility model.

Referring to Fig. 1 and Fig. 2, present embodiment is an intercom, and its battery 2 is installed on the main frame 1 by battery latching device of the present utility model.

Referring to Fig. 1 to Fig. 7, battery latching device among the embodiment comprises the button bit 21 of the screens that is located at battery 2 tops (indicating among the figure) and battery 2 lower ends, be located at the draw-in groove 11 at main frame 1 top, the battery that is located at main frame 11 bottoms pushes away buckles 31, two battery grabs 32 and two shell fragments 33, the upper end of battery grab 32 is " 7 " font hook, the lower end of battery grab 32 is cylindrical, be installed in the corresponding circle hole 13 of main frame 1 bottom, battery grab 32 can be around the axis swing of its cylindrical lower end, battery pushes away to be buckled 31 and comprises base plate and be located at pushing away of base plate inboard and buckle, the both sides of base plate insert in the groove of main frame 1 bottom, push away button bit between two battery grabs 32 and with they clampings mutually, the end face of phase clamping is the inclined-plane that mates mutually, cooperation by this inclined-plane, battery push away buckle 31 when moving up and down two battery grabs 32 inwardly close up or outwards open, two shell fragments 33 are installed on the outside of two battery grabs 32 with preloading condition; The screens at battery 2 tops is inserted in the draw-in groove 11 at main frame 1 top, battery 2 is connected on the main frame 1, the upper end hook that the button bit 21 of battery 2 lower ends presses down back and two battery grabs 32 is interlockingly connected, the inner arc face of battery grab 32 upper ends snaps in the spigot surface of battery 2 lower end button bits 21 for ease of it, and this arc surface matches with battery 2 lower end button bits 21 respective ramp.

During assembling, extremely shown in Figure 7 as Fig. 5, elder generation packs two shell fragments 33 in the main frame 1 bottom draw-in groove 12, again the cylindrical lower end of two battery grabs 32 is inserted in main frame 1 bottom circular aperture 13, and battery grab 32 broken into two with one's hands spacing 32 pairs of shell fragments 33 of battery grab have certain precompressed at the corresponding position of bone 14 two ends, main frame 1 bottom, battery is pushed away buckle 31 main frame 1 relevant positions of packing at last, position-limiting action is played to it in main frame 1 bottom tiltedly button 15, and battery pushes away buckle 31 and the mutual clamping in inclined-plane that is complementary of battery grab 32.

When need are installed on battery 2 on the main frame 1, earlier the screens at battery 2 tops is inserted in the main frame 1 top respective card slot 11, push battery 2 afterbodys again, in this process, the upper end arc surface of the inclined-plane extruding battery grab 32 of battery 2 lower end button bits 21, making battery grab 32 outwards rotate opens and extrusion elastic 33, when battery 2 lower end button bits 21 enter two battery grabs, 32 centres fully, the bounce of shell fragment 33 forces battery grab 32 inwardly to rotate to close up and tangles battery 2 lower end button bits 21, realization battery 2 is connected with main frame 1, and battery 2 is locked on the main frame 1.

When need with battery 2 when main frame 1 takes off, only with hand according to battery push away buckle on 31 triangle indicate shown in direction promote battery gently downwards and push away and buckle 31, battery 2 lower end button bits 21 are separated with the battery grab 32 that is arranged at main frame 1 bottom, realize the unlatching of battery 2.

Shell fragment in the foregoing description also can adopt other elastomers such as spring.

The above only is a preferable embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
