Abstract
The utility model provides a lock which is simple in structure, easy to open and close, and low in locking accuracy. The lock structurally comprises a lock hook and two elastic clamping jaws fixed on a lock plate, wherein one end of each of the two elastic clamping jaws is hinged via a return spring, and the other end of each of the two elastic clamping jaws is fixed with a pulley; the two pulleys of the two elastic clamping jaws are tangential during the closing of the lock; and the two elastic clamping jaws are encircled to form a clamping area for accommodating the lock hook. The lock hook is seized by the elastic clamping jaws to realize locking, in case of the need of locking, the lock hook only needs to penetrate through the two tangential pulleys, and after the lock hook penetrates through the pulleys and enters in the clamping area, the pulleys are returned under the return action of the elastic clamping jaws, thus finishing locking; similarly, the opening process of the lock is equally simple; additionally, because the lock hook only needs to be aligned with an area in front of the tangential points of the two pulleys, a requirement on the locking accuracy is low, and the case that locking is difficult due to the dislocation of the lock hook caused by the loosing of furniture after being used for a long time is avoided.
Description
Technical field
The utility model relates to the furniture technical field, is specifically related to a kind of lock.
Background technology
Existing family has a lot of places and need use and open and closure simple magnetic lock all, but magnetic is locked owing to the easy loss of excitation of magnet is not durable.The magnetic lock has more existing use in the near future owing to the folding number of times frequently causes closed hypodynamic situation at present.In addition and since a lot of furniture are long-term use after, owing to reasons such as hinge are soft, can cause lock-bit not align and influence the folding of lock.
Summary of the invention
The purpose of this utility model is that proposition is a kind of simple in structure, and folding is easy, the lock that sealed required precision is low.
The lock that provides according to the utility model, key is to comprise latch hook and two elastic card claws that are fixed on the jam plate, one end of described two elastic card claws is hinged by back-moving spring, the other end is all fixed a pulley, two pulleys of described two elastic card claws are fashionable tangent at locking, and two elastic card claws surround the clamping zone that can hold described latch hook.
Lock of the present utility model is bitten latch hook by elastic card claw and is realized sealedly, needs when sealed, latch hook only need pass two tangent pulleys and get final product, after the lock structure passed pulley and enters clamping zone, pulley is return under the reset response of elastic card claw, has just finished sealed; In like manner, the opening process of lock is simple equally; In addition, because the front region that latch hook only need be aimed at the points of tangency of two pulleys when sealed get final product, so sealed required precision is low, avoids appearing at furniture and use for a long time and afterwards softly cause not contraposition of latch hook and be difficult to sealed situation.
Further, described back-moving spring is fixed on the jam plate by riveted.Can adjust the back-moving spring position to adjust the pulley points of tangency by firm power latch hook occurring not during alignment situation like this.
Further, described back-moving spring is fixed by welding on the jam plate, to reduce cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and operating principle etc. are described in further detail.
Embodiment 1:
As Fig. 1, lock of the present utility model comprises latch hook 1 and two elastic card claw 21 and elastic card claws 22 that are fixed on the jam plate 2, one end of elastic card claw 21 and elastic card claw 22 is hinged by back-moving spring 3, other end fixed block 210 and pulley 220, two pulleys 210 and the pulley 220 of elastic card claw 21 and elastic card claw 22 are fashionable tangent at locking, and two elastic card claws 21 and elastic card claw 22 surround the clamping zone A that can hold latch hook 1.Back-moving spring 3 can be to be fixed on the jam plate 2 by riveted, can adjust back-moving spring 3 positions to adjust the points of tangency of pulley 210 and pulley 220 by firm power latch hook 1 occurring not during alignment situation; Also can be to be fixed by welding on the jam plate 2, to reduce cost.
