Model utility content:
The purpose of this utility model is the deficiency existing for prior art, a kind of magnetic lock latch is provided, it not only can realize two flexible connections between individual components, and go for multiple parts simultaneously with being flexibly connected of other parts, there is registration, feature that joint efficiency is high.
For achieving the above object, magnetic lock latch of the present utility model is made up of locking device and positioning device, wherein, locking device has a shell, outer casing bottom has a up big and down small steel ball chute, in steel ball chute, be provided with steel ball, in shell, be provided with steel ball briquetting and the locking spring that can coordinate with magnetic patch in the upper end of steel ball chute, locking spring is pressed on steel ball in steel ball chute by steel ball briquetting; Positioning device includes locating stud, removable insole pieces, retaining spring and fixed block, wherein, locating stud front end is can be through the locking section of steel ball chute, locking section middle part forms the arc groove coordinating with steel ball, removable insole pieces and retaining spring are set on locating stud, and fixed block is connected with the rear end of locating stud.
As technique scheme preferably, described steel ball briquetting can slide in the enclosure, its middle part offers spring locating slot and locating stud pilot hole.
As technique scheme preferably, described locking spring is volute spring, its upper end is against on the inner top surface of shell, lower end is against on the bottom surface of spring locating slot.
As technique scheme preferably, the position of the described corresponding steel ball chute in steel ball briquetting bottom forms taper bump.
As technique scheme preferably, described locating stud forms positioning step in a locking section rear end.
As technique scheme preferably, described locating stud rear end is thread section, fixed block is and the locking nut of thread section screw-thread fit.
As technique scheme preferably, described shell lower end is provided with connecting plate.
The beneficial effects of the utility model are: locking device and positioning device can be separately positioned on two individual components, in the time that needs link together two parts, locating stud is aimed to steel ball chute to be inserted in shell and can locate and locking by realizing steel ball and coordinating of arc groove, and need to be by two isolation of components time, only need apply magnetic force by the steel ball briquetting in shell, make it overcome the elastic force of locking spring and remove the pressuring action to steel ball, steel ball leaves after arc groove, locating stud can exit steel ball chute under the elastic force effect of retaining spring, thereby two parts that link together are separated.Because the connection of locking device and positioning device has feature fast, accurately, go for multiple parts simultaneously with being flexibly connected of other parts, joint efficiency is very high.
Accompanying drawing explanation:
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is sectional structure schematic diagram of the present utility model;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1;

Embodiment:
Therefore the following stated only, for embodying the preferred embodiment of the utility model principle, does not limit protection domain of the present utility model.
See shown in Fig. 1 to Fig. 3: magnetic lock latch of the present utility model is made up of locking device 10 and positioning device 20, wherein:
For facilitate locking device 10 and other parts be connected and fixing, shell 11 lower ends are provided with connecting plate 16, connecting plate 16 peripheries can be offered tapped hole or riveted holes.
Locating stud 21 forms positioning step 213 in locking section 211 rear ends, and positioning step 213 can play position-limiting action to removable insole pieces 22.In addition, locating stud 21 rear ends are thread section 214, and fixed block 24 is and the locking nut of thread section 214 screw-thread fit.Locking nut is flexibly connected with locating stud 21, not only can facilitate the installation of retaining spring 23, and can regulate the elasticity of retaining spring 23.
Working principle of the present utility model is as follows: in the time that the locking section 211 of locating stud 21 front ends is inserted in steel ball chute 12, locking section 211 is backed down two steel balls 13, force steel ball 13 to separate to the left and right sides in steel ball chute 12, until steel ball 13 blocks the arc groove 212 at locking section 211 middle parts; Now, insert in the process of shell 11 in locking section 211, removable insole pieces 22 runs into and makes retaining spring 23 compressions produce spring-back force for the base plate of fixing and locking device 10 stops, spring-back force produces locking section 211 trend that exit from steel ball chute 12 that make, but because steel ball 13 is subject to the impacting force that locking spring 15 applies by steel ball briquetting 14, forcing steel ball 13 to be stuck in arc groove 212 cannot leave, locking section 211 also just cannot exit from steel ball chute 12, makes locating stud 21 be achieved self-locking and location.In the time that steel ball briquetting 14 is subject to strong magnetic attachment and magnetic force and is greater than the elastic force of locking spring 15, steel ball briquetting 14 overcomes the elastic force of locking spring 15 and removes the pressuring action to steel ball 13, steel ball 13 leaves arc groove 212, now, locking section 211 exits under the spring-back force effect of retaining spring 23 from steel ball chute 12, thereby realizes separating of locking device 10 and positioning device 20.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
