Abstract

The utility model belongs to lock technical field and discloses a magnetic theftproof lever lock which comprises a lock body, a lock core mounted in the lock body and a theftproof bolt connected with the lock core, a lock tongue box corresponding to the lock body, a lock tongue sleeve mounted in the lock body, a lock tongue mounted in the lock tongue sleeve, a magnet mounted in the lock tongue box corresponding to the lock tongue, a lock tongue pull rod, a reset plate, a handle shaft and a reset spring; wherein, the rear end of the lock tongue pull rod is extended out of the front end of the lock tongue sleeve, and the lock tongue pull rod is connected with the rear end of the lock tongue, the reset plate is contacted with the rear end of the lock tongue pull rod, the handle shaft is connected with the reset plate, one end of the reset spring is connected with the lock body, and the other end of the reset spring is connected with the handle shaft. The lock tongue not only cannot wear the door frame, but also cannot cause the problem that the lock tongue is extended out of the lock body all the time and collide with the lock tongue box to cause the difficult closing situation.

Description

The magnetic anti-theft hand holding lock

Technical field

The utility model belongs to the technical field of lock.

Background technology

The front end of present hand holding lock dead bolt leans out lock body, and when at closing time, dead bolt and dead bolt box bump, because the front end of dead bolt is a camber, dead bolt in the first compression and back lock bolt sleeve, springs in the dead bolt box under the pressure of dead bolt box again, finishes the process of closing the door; When opening the door, rotate the hand holding lock handle, handle drives dead bolt, and dead bolt is retracted in the lock body, finishes the process of opening the door.Because dead bolt is the state of leaning out that is in all the time, when closing, dead bolt at first contact with doorframe, in the course of time, the marking of the one deeper and deeper black that can on doorframe, rub out, the utmost point is not attractive in appearance.Dead bolt also often can not be pressed into lock body flexibly in the process of closing the door, and causes the pass hindered lift-cabin door.Long-term collision also can make dead bolt surface produce indenture, cause close the door more dumb.

Summary of the invention

For overcome that dead bolt that hand holding lock leans out at closing time and the collision of dead bolt box cause close the door dumb and dead bolt is exposed at the damage that outside the lock body doorframe is caused, just the utility model provide a kind of only under locking state dead bolt be exposed at the antitheft hand holding lock of magnetic force outside the lock body.

This magnetic anti-theft hand holding lock, comprise lock body and be contained in lock body interior lock core and the anti-theft bolt that is connected with lock core, the dead bolt box corresponding with lock body, be contained in the lock bolt sleeve in the lock body, be contained in the dead bolt in the lock bolt sleeve, be contained in the magnet in the dead bolt box corresponding with dead bolt, end stretches out lock bolt sleeve front end and the terminal dead bolt pull bar that is connected of dead bolt, with the terminal reseting plate that contacts of dead bolt pull bar, the Handle axis that is connected with reseting plate, an end is connected the return spring that the other end is connected with Handle axis with lock body.

Because dead bolt is at ordinary times in lock bolt sleeve, when only the dead bolt box is corresponding with latch bolt position after dead bolt is on the door lock, dead bolt just enters the dead bolt box by lock bolt sleeve under the gravitation of magnet, the doorframe so dead bolt neither can wear and tear can the difficult problem of closing the door not occur owing to dead bolt leans out the collision of lock body and dead bolt box all the time yet.

Description of drawings

Accompanying drawing shows embodiment of the present utility model, wherein:

Figure 1 shows that the elevational cross-sectional view of magnetic anti-theft hand holding lock;

Figure 2 shows that along the sectional view of A-A line shown in Figure 1.

The specific embodiment

Magnetic anti-theft hand holding lock as shown in the figure, comprise lock body 1 and be contained in lock core 2 and the anti-theft bolt 3 that is connected with lock core 2 in the lock body 1, the dead bolt box 4 corresponding with lock body 1 is contained in the lock bolt sleeve 5 in the lock body 1, and the axis direction of lock bolt sleeve 5 and lock body 1 vertical acutangulate.Be contained in the dead bolt 6 in the lock bolt sleeve 5, be contained in the magnet 7 in the dead bolt box corresponding with dead bolt 6, end stretches out the dead bolt pull bars 8 that lock bolt sleeve 5 front ends are connected with dead bolt 6 ends, dead bolt pull bar 8 be "

" font.With the dead bolt pull bar 8 terminal reseting plates 9 that contact, Handle axis 10, one ends that are connected with reseting plate 9 are connected the return spring 11 that the other end is connected with Handle axis 10 with lock body 1.At closing time, dead bolt enters the dead bolt box under the effect of magnet magnetic force, and dead bolt is got back in the lock bolt sleeve under the pulling force of self gravitation and handle when opening the door, and dead bolt only when locking the door, leans out lock body.
