Description

The trolley Series lock

The utility model relates to a kind of lock of trolley.

Employed all kinds of trolleys in present airport and the supermarket, though made things convenient for the user to put object and shopping, the anti-theft measure that the use of trolley and managerial demand are special for example needs to adopt chain and special-purpose lock locking, thereby very inconvenient.

Therefore, the purpose of this utility model provide a kind of need not antitheft, open and be fit to the trolley Series lock that use in places such as airport, supermarket easily.

For achieving the above object, trolley Series lock of the present utility model comprises: a lock housing body, with inner chamber of a bottom-open is fixedly connected on a base plate and a dead bolt that covers described inner chamber on the housing bottom; Be characterized in that described inner chamber comprises that one has cannelure, the through hole on a side and first recess of putting the coin mouth and second recess on opposite side; Described base plate is formed with a transverse concave groove and counterbore; Described dead bolt is plugged in the described cannelure movably by the described coin mouth of putting, it has vertically arrange notched puts coin recess, lock tongue slot and is arranged on two seams on the relative opposite side with described breach, is formed with recessed plane and transition inclined-plane in described lock tongue slot zone; Also comprise: be arranged on the spring-loaded mechanism between described dead bolt insertion end and inner chamber end wall; One snap close that is connected with chain, it has the handle of fixedlying connected with snap close, described snap close is plugged in the described transverse concave groove, one can be up or down by described lock tongue slot and insert described bonnet lock hole and the base plate counterbore in the snap close pin; Be arranged on one second spring-loaded mechanism of described snap close pin upper end; One is arranged on the switching mechanism that is used to lock and discharge described snap close and dead bolt in described second recess; And be arranged on a detector in described first recess.

Adopt technique scheme,, dead bolt is pushed lock housing body cannelure from putting the coin mouth, can finish the unlatching of the Series lock of trolley as long as place coin in the putting in the coin recess of dead bolt; And snap close is inserted described transverse concave groove, and snap close front end pushing tow switching mechanism moves, and dead bolt withdraws under spring action, just can make the snap close pin insert counterbore on snap close and the base plate by corresponding spring mechanism, and gets coin and finish the pass closed procedure of Series lock.Therefore manipulate very conveniently, and need not any other anti-theft measure.

Specify the trolley Series lock of the utility model one preferred embodiment below with reference to accompanying drawings, so that clearlyer understand the purpose of this utility model, characteristics and advantage.

Fig. 1 is the horizontal cross of the trolley Series lock of the utility model one preferred embodiment;

Fig. 2 is the sectional view of being got along A-A line among Fig. 1.

As shown in the figure, the trolley Series lock of the utility model one preferred embodiment comprises: a lock housing body 1, as shown in Figure 2, it has the inner chamber of a bottom-open, it comprise have the cannelure 17 of putting coin mouth 19, at the through hole on the inboard 30 and first recess 22 and second recess 18 on another inboard; One is fixedly connected on the base plate 16 that covers described inner chamber on the housing bottom, has a transverse concave groove 29 and a counterbore 41 on it; One is plugged in dead bolt 4 in the described cannelure 17 movably by the described coin mouth of putting, it have vertically arrange have a breach 40 put coin recess 20, lock tongue slot 21 and with breach 40 opposite sides on two seams 46 that form, can on arbitrary side of dead bolt 4, form according to the coin recess 20 of putting easy to use; Also comprise: be provided with a spring-loaded mechanism in the insertion end 24 of

dead bolt

4 and 25 of the end walls of cannelure 17, it is made up of two juxtaposed support springs 26 and its supporting base 27; One snap close 2 that is connected with chain 15, the end portion that it is formed with snap close pin-and-hole 42 handles 14 and snap close 2 forms one, snap close 2 can laterally be plugged in the transverse concave groove 29 by through hole 30 movably, and a snap close pin 5 can insert in described snap close pin-and-hole 42 and the counterbore 41 up or down by described lock tongue slot 21; Be arranged on one second spring-loaded mechanism of snap close pin 5 upper ends, by the counterbore 31 that forms on the snap close pin upper end, intercalation that housing 1 inner chamber upper wall forms in described counterbore 31 boss 32 and be set in the inner chamber upper wall and the shoulder of snap close pin between support spring 8; One is arranged on being used in the recess 18 locks switching mechanism with releasable catch 2 and dead bolt 4, it is by a switchboard 6 and place the spring 7 on the switchboard 6 to form, switchboard top is formed with two projectioies 34, its underpart is formed with two kidney slots 35, two projectioies 37 that formed by housing recess upper wall are embedded in the described kidney slot 35, the switchboard both sides are formed with bearing 36, and spring 7 is arranged between the sidewall 38 of bearing 36 and recess 23; And being arranged on a detector 3 in described first recess 22, it embeds cover 39 by one, is located in the connecting pin 45 in cover roof hole movably and is arranged on support spring 13 compositions between the bottom surface of second recess, 22 sidewalls and connecting pin 45.This detector 3 can be regulated by the spring that placement has different coefficient of elasticity according to the number of coins that service condition is placed; In case after adjusting, if do not place, the placement amount do not meet with the service condition that sets, then all can not opening lock catch 2.After being inserted coin recess 40, coin promotes dead bolt 4 mobile and compression spring 26 in cannelure 17, this moment dead bolt put coin part easily the connecting pin 45 by detector 3 with its jack-up and compress spring 13, when the shoulder 44 of the inclined-plane of dead bolt jack-up snap close pin 5, snap close pin 5 just rises and leaves counterbore 41, snap close pin-and-hole 42, this moment, snap close 2 was owing to throwing off with the snap close pin and ejecting under the spring action of switching mechanism, switchboard 6 moves under the effect of spring 7 to the inside, and the seam 46 of embedding dead bolt 4, this moment, spring 26 was in compressed state, dead bolt is in inner extreme position, and the trolley Series lock is just finished opening process.If do not place coin, just then connecting pin 45 snaps in breach 40 under 13 effect of spring, at this moment, just dead bolt 4 inwardly can not be promoted, thereby can not make snap close 2 throw off snap close pins 5.When snap close being inserted in the snap close groove 29, the snap close front end just withstands switchboard 6 and moves until breaking away from dead bolt, dead bolt just in its back-end spring 26 effect ejects down automatically, snap close pin 5 moves down the waist shape snap close pin-and-hole 42 that inserts snap close 2 and then inserts in the counterbore 41 under the effect of its spring 33 simultaneously, at this moment can take out coin, the trolley Series lock is just finished the pass closed procedure.When reality was used, by other hand push lock of chain 15 series connection, these hand push locks all were to be fixedly mounted on the handlebar, during the snap close shifted laterally of trolley lock, can open last adjacent hand push lock.
