Abstract
The utility model discloses an unexpected locking preventing door lock which is characterized by being composed of a lock tongue, a mounting hole, a spring, a pin shaft, a connecting rod, a rotating hole, a cam and a lock body, wherein the mounting hole is formed in the lock tongue; the pin shaft is arranged at one side of the lock tongue and connected with the lock tongue through the spring; the connecting rod is fixed on the lock tongue through a rotating pair, one end of the connecting rod is connected with the pin shaft, the other end of the connecting rod is connected with the cam, and the connecting rod mainly plays a role in transferring force; and the cam is arranged in the lock body and connected with the rotating hole and rotates along with the rotation of the rotating hole. When a door is needed to be closed, a handle is rotated, the pin shaft can automatically shrink, and the lock tongue is rebounded, thus the door lock is locked tightly; and if the handle is not rotated, the lock tongue can be clamped by the pin shaft and can not be rebounded, and the door lock can not be locked tightly under non-artificial factors such as wind force and the like when the door is in an opened state, so that the inconvenience caused by automatic door locking under unexpected non-artificial factors is effectively overcome.
Description
Technical field:
The utility model relates to a kind of door lock, especially a kind of anti-unexpected locking type door lock.
Background technology:
What the door lock that present market is used was generally all used is pin tumbler lock, door lock automatic locking when visit in pass, but this makes troubles also for people's life, such as: sometimes people need door be in open mode, but under the non-artificial factors such as wind-force, door lock is automatic locking also.
The utility model content:
The utility model purpose is to provide a kind of anti-unexpected locking type door lock for the deficiency that solves above-mentioned technology, and it is mainly that a bearing pin is installed on dead bolt, when needs at closing time, rotary handle, bearing pin shrink automatically, dead bolt rebounds, door lock locking; If rotary handle not, dead bolt is blocked by bearing pin, can't rebound, and door lock can't be locked.
In order to address the above problem, the utility model solves the technical scheme that its technical problem adopts and is: a kind of anti-unexpected locking type door lock is characterized in that: it by dead bolt, installing hole, spring, bearing pin, connecting rod, revolve hole, cam and lock body and form.Described installing hole is located on dead bolt; Described bearing pin is arranged on dead bolt one side, and is connected with dead bolt by spring; Described connecting rod is fixed on dead bolt by revolute pair, and the one end is connected with bearing pin, and the other end is connected with cam, and it mainly plays the effect of transmission power; Described cam is arranged in lock body and revolves hole and be connected, and rotates with the rotation of revolving hole.
The beneficial effects of the utility model are: at door, be in open mode, under the non-artificial factors such as wind-force, door lock can't automatic locking, has effectively solved door automatic locking and inconvenience of occurring under the non-artificial factor of accident.
The accompanying drawing explanation:
For the technical scheme that illustrates that more clearly the utility model is implemented, below in conjunction with accompanying drawing explanation and embodiment, the utility model is further illustrated.
Fig. 1 is the utility model structural representation.
Wherein, 1-dead bolt, 2-installing hole, 3-spring, 4-bearing pin, 5-connecting rod, 6-revolve hole, 7-cam, 8-lock body.
The specific embodiment:
As shown in Figure 1, a kind of anti-unexpected locking type door lock is characterized in that: it by dead bolt, installing hole, spring, bearing pin, connecting rod, revolve hole, cam and lock body and form.Described installing hole is located on dead bolt; Described bearing pin is arranged on dead bolt one side, and is connected with dead bolt by spring; Described connecting rod is fixed on dead bolt by revolute pair, and the one end is connected with bearing pin, and the other end is connected with cam, and it mainly plays the effect of transmission power; Described cam is arranged in lock body and revolves hole and be connected, and rotates with the rotation of revolving hole.
As shown in Figure 1, need at closing time people, rotary handle, revolve hole and cam and following handle and rotating, under the effect that cam rotates, and link motion, thereby the contraction of drive bearing pin, dead bolt rebounds, door lock locking; Under the non-artificial factor of accident, handle does not rotate, and bearing pin is in the state of stretching out under the effect of spring, and dead bolt is stuck, and can't shrink, and door lock can't be locked, and has effectively solved door automatic locking and inconvenience of occurring under the non-artificial factor of accident.
Above embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model, all should fall in the definite protection domain of claims of the present utility model.
