Description

Bag lock

Technical field

The utility model relates to a kind of technical field of bag lock.

Background technology

Case and bag are products that people will often use, on case and bag, to use this lockset of bag lock, at present traditional bag lock is not because scientific and reasonable in the design, as adopt the latch hook of a hook pin to lock, so following problem of ubiquity, when you do not close case and bag fully, the lock that case and bag can occur has only one side to be lockable, and be not lockable yet on one side in addition, there is unsafe factor, when you during with the article overfill in the case and bag, may be because the article that you adorned break away from the latch hook of case and bag the shell crimp of case and bag, case and bag occur and opened by mistake and wait embarrassment and unsafe situation; When your case and bag accidentally when eminence falls and the latch hook that case and bag occur is thrown off because of external force and the awkward scene that case and bag are opened occurred.As the patent No. is that 97234629.5 Chinese patent " bag lock " discloses a kind of lockset, this lockset comprises lock housing, lock core, button, iron wedge angle piece, slide block, pulling block, push button etc., button is fixedlyed connected with iron wedge angle piece, slide block links to each other with a brute spring with pulling block, the pulling block bottom bends downwards, insert in the groove of push button behind the protruding beam on the lock housing at interval, on protruding beam, have groove, and opening is set in the relevant position on pulling block, in groove, place a steel ball, steel ball can not encase along the groove rolling but by the iron bonnet can deviate from groove, this bag lock can only be opened just putting Shi Caineng, the lock core firm and durable, and the sliding capability of slide block is good, applicable to briefcase, on the multiple case and bag such as luggage, though it has its progressive one side, it is owing to adopting single lock point to lock, so there is above-mentioned similar defective inevitably, need us to develop the bag lock that carries out multi-point fastening that makes new advances, realize that locking firmly, be not easy to become flexible, the purpose that positive opening is few.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of bag lock at prior art, and it is simple and reasonable, and assembling is produced easily, and adopt the multi-point fastening structure, and improved latching force, be not easy to become flexible, reduce the enforced opening possibility, safety is better.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this kind bag lock, it includes lock box, lock core, latch hook, springboard, slide block, spring, lock box is movably hinged with springboard by pivot pin, be provided with on the springboard lock core is installed, it is characterized in that centre position, lock box bottom is provided with the jacking block that can move forward and backward, be supported with the jacking block spring between the inboard wall of jacking block and lock box, simultaneously the jacking block top cooperates with fixed block below the springboard, and the fixed block below the springboard is movably hinged with a left side, right connecting rod, a left side, the right connecting rod lower end respectively with a left side, right slide block is movably hinged, a left side, right slide block is installed in that the position can horizontally slip under the lock box under connecting rod promotes, an and left side, be supported with sliding block spring between right slide block and the lock box, the side of lock box has three locating holes, the interfix hole is corresponding with jacking block, a left side, a right locating hole and a left side, right slide block correspondence, be equipped with latch hook simultaneously, have in the middle of the described latch hook to be inserted into and remove the pin that cooperates with jacking block in the interfix hole, about be and a left side, right slide block cooperates the hook pin for its locking, springboard is plugged with the snap close that can stretch away from the end the inside of pivot pin, be supported with latch spring between snap close and the springboard, the lockhole of the inboard face of the clasp of snap close and lock box cooperates springboard is locked on the lock box.

Above-mentioned jacking block has axis hole, and in lock box, the jacking block spring of two front and back also is through on this pivot pin simultaneously by the pivot pin positioning and fixing.

Above-mentioned left and right small end is hinged.

Above-mentioned lock box inboard forms projection and cooperates locking with shift fork on the lock core.

Compared with prior art, advantage of the present utility model is: because it adopts two hook pin on the latch hook to cooperate locking with slide block, so the lock point is many, improved latching force, make case and bag more firm, be not easy to become flexible, reduced the possibility of enforced opening, adopt jacking block to cooperate simultaneously with fixed block on the springboard, latch hook must put in place, just can lock, the springboard that closes has reduced mistake and has locked phenomenon, so this bag lock main feature is not exactly when case and bag are closed fully, the lock of case and bag can't cut out, and promptly has only when you close case and bag fully, and you just can depress the springboard of lock and case and bag are pinned; And it is half-open to have avoided lock in the past that the latch hook appearance of case and bag is partly locked, even the case and bag that pin under external force, and latch hook is failed to hook fully and caused case and bag to be opened; The embarrassment that can also avoid case and bag to be subjected to the effect of any external force and bag lock is opened, and this lock can avoid the double swerve of the last lower casing of the case and bag that pin guarantees that the article in your case and bag never are scattering into the outside after pinning; The overall structure advantages of simple, assembling is produced easily, and cost is low, is adapted at promoting the use of on the case and bag.
