Embodiment
The utility model will be further described below in conjunction with embodiment.
As shown in Figure 1 and Figure 2, a kind of battery compartment lid clamping device, battery compartment cap body 1 is installed on the casing housing 2 and with casing housing battery compartment opening and matches, and a side of described battery compartment cap body 1 is provided with a slice inserted sheet 103 at least, the corresponding slot 201 that equal number is set on the described housing 2; The opposite side of lid 1 is provided with a hook 101 at least, one slide plate 4 is installed on housing 2 inwalls, slide plate 4 corresponding lid hook places are provided with a trip 401, trip 401 matches with hook 101, one push button 3 is set on the slide plate 4, push button 3 is provided with an elasticity reset device 5 by outside the 206 outstanding housings of the groove on the housing on the housing, an end of elasticity reset device 5 is connected with slide plate 4.Slide plate 4 can move in the restriction moving range relative to housing 2, and it moves to making moving back and forth of trip 401 lockings or the hook 101 that gets loose.
For the misoperation of anti-limited slip plate 4, a locking device is installed on the described housing 2, an end of this locking device is emerging in outside the housing, and the other end is arranged on the slide plate.Locking device can adopt various ways, as the mode that present embodiment adopted, described locking device comprises fixed head 6, screw 7, one end of fixed head 6 is provided with a nut seat 604, one screw 207 is set on the housing, the central axes of the central axis of screw 207 and nut 604, as shown in Figure 4.Propping up slide plate 4 by screw 7 can not slide slide plate.Described locking device also comprises E type snap ring 8, and E type snap ring 8 is stuck in neck 701 places of screw.E type snap ring 8 prevents that screw 7 from getting loose and lose from housing.
Locking device also can be other modes.Described locking device is a bayonet lock, and an end of bayonet lock is emerging in outside the housing by the through hole on the housing, and the other end can insert the locking hole (groove) of corresponding setting on the slide plate or prop up the edge of slide plate.Bayonet lock pins slide plate.When opening, cocked bayonet lock, slide plate 4 slidably promote slide plate 4 by push button 3, and trip 401 is thrown off with hook 101, and lid 1 is separable with housing 2.
Elasticity reset device also has multiple mode can supply to adopt.Elasticity reset device makes slide plate 4 remain on locking-in state.As shown in Figure 3, described elasticity reset device is a spring 5, and an end of spring 5 is installed on the spring fixed seat 209 of housing, and the other end is enclosed within on the spring fixed axis 407 of slide plate.
Another form of elasticity reset device, described elasticity reset device are shell fragment, and an end of shell fragment is fixed on the housing, and the other end props up the edge of slide plate.
Be provided with one as described in Figure on the slide plate 4 and eject shell fragment 403.Eject shell fragment 403 and withstand on the inwall of battery cover lid 1, after hook 101 gets loose from trip 401, eject shell fragment 403 lid 1 is backed down, be convenient to the user and open battery cover, as shown in Figure 5.The shell fragment 403 that ejects of present embodiment is installed in the slotted hole groove 205.
As shown in Figure 4, on the described trip 401 inclined-plane is set, an inclined-plane that matches is set on the hook 101.The design on inclined-plane allows battery cover when closing, and the ramp effect of hook 101 promotes slide plate 4 forward on the inclined-plane of trip 401, and after hook 101 put in place, the effect trip 401 by elasticity reset device was stuck on the hook 101, and battery cover is locked.
As Fig. 1, Fig. 2 and shown in Figure 4, the battery cover 1 of present embodiment has two inserted sheets 103, insert in housing 2 stopper slots 201, promote battery cover 1, its hook 101 inclined-planes promote slide plate trip 401 inclined-planes, slide plate moves right, and installs to the position until battery cover 1, and back-moving spring 5 promotes the slide block 4 slide block 4 upper clamping hooks 401 locking battery door that reset left.Slip hole slot 405 is set on the slide plate 4, and correspondence is provided with fixed leg 208 on the housing 2.Slide plate 4 is enclosed within on the fixed leg 208 by slip hole slot 405, and fixed head 6 is fixed on the fixed leg 208 by through hole 601 by screw, and fixed head 6 limits moving axially along fixed leg of slide plates 4.The threaded portion 702 of screw 7 is tightened in the nut 603 of slide plate fixed head 6, and the plates 408 of slide plate 4 are blocked in the terminal pin of screw position 703, and slide block 4 can not be moved right, thereby the battery cover 1 that links closely, and battery cover can not get loose.When opening, unscrew screw 7, snap ring 8 is in the neck 701 of the inboard fixed screw 7 of housing, and screw 7 pines and not taking off can promote push button 3 this moment, and push button 3 is fixed in the groove 404 of slide block 4, puts in place when slide block 4 moves right, and gets loose with battery cover hook 101.Eject shell fragment 403 on the slide block and eject battery cover, at this moment dismantled and assembled battery.
