Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, technical solution of the present invention will be carried out below
Detailed description.Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Base
Embodiment in the present invention, those of ordinary skill in the art are obtained all without making creative work
Other embodiment belongs to the range that the present invention is protected.
As shown in Figure 1, lock body includes shell, shell side is connected with bolt plate 3, and shell is made of pedestal 1 and cover board 2,
It is formed with dead bolt hole 31 in bolt plate 3, is equipped with lock tongue 4 in the shell, lock tongue 4 can stretch out or retract the dead bolt hole 31
It is interior.
As in Figure 2-4, resetting-mechanism 5 is equipped in the pedestal of the lock body 1, resetting-mechanism 5 is connected with the lock tongue 4,
And when lock tongue 4 retracts in dead bolt hole 31, resetting-mechanism 5, which can act on lock tongue 4, makes it pop up dead bolt hole 31.Above-mentioned lock tongue
4 include one portion 41, is connected to the front end of resetting-mechanism 5 by body portion 41, and can be rotated relative to resetting-mechanism 5,
4 face of side lock tongue in body portion 41 is the first locking surface 42, and lock tongue 4 face in the other side is the second locking surface 43, is locked as shown in Figure 3
4 state of tongue, end slope of first locking surface 42 relative to bolt plate 3, and end face of second locking surface 43 relative to bolt plate 3
Vertically, when the lock body being located in door is closed towards door, the second locking surface 43 and door frame contact, the rotation commutation of lock tongue 4, the first lock
Only face 42 becomes vertical with the end face of bolt plate 3, and the second locking surface 43 becomes the end slope with bolt plate 3, passes through second
The characteristic for favouring doorframe of locking surface 43, during the two mutual extrusion, lock tongue 4 is extruded into dead bolt hole 31, and
When final lock body is docked with the button box on doorframe, lock tongue 4 is sprung into button box.Similarly, as shown in figure 4, before enabling, first
Locking surface 42 is vertical with the end face of bolt plate 3, when Jiang Men is won over, the first locking surface 42 and door frame contact, and the first locking surface
42 become inclined in the end face of bolt plate 3, and in door opening process, lock tongue 4 is squeezed in compression and back dead bolt hole 31, realize opening door
It opens, after door is opened, lock tongue 4 pops up dead bolt hole 31 under the action of resetting-mechanism 5 again.
Further, the tail end of the first locking surface 42 and the second locking surface 43 is arc-shaped, due to opening the door and at closing time, locking
Tongue 4 can rotate, and to avoid lock tongue 4 in rotation, it is dry that the first locking surface 42 and the second locking surface 43 can encounter dead bolt hole 31
The rotation of lock tongue 4 is disturbed, so that the tail end of the first locking surface 42 and the second locking surface 43 is arc-shaped, this can be preferably solved and ask
Topic.
As it can be seen in figures 5 and 6, the resetting-mechanism 5 includes the ram seat 11 on pedestal 1, formed in ram seat 11
There is a groove, a push rod 51 is set up in groove, push rod 51 is limited in groove and can be along the direction straight line towards dead bolt hole 31
Movement, the lock tongue 4 are connected to the front end of push rod 51 by shaft 52, allow to rotate relative to push rod 51, in addition push away
The first spring 53 is cased on bar 51,53 meeting of the first spring is so that lock tongue 4 has the trend of pop-up dead bolt hole 31 always, as long as locking
For tongue 4 not in the case where by external force, lock tongue 4 will be ejected dead bolt hole 31, so that lock tongue 4 is located at buckleing for doorframe when in door closure
When in box, lock tongue 4 can be matched with button box, prevent door from opening easily.
As shown in fig. 7, the front end of the push rod 51 is also formed with mandril 54, shaft 52 is set on the mandril 54, is locking
Cavity 411 is equipped in the body portion 41 of tongue 4, the mandril 54 on push rod 51 extend into inside cavity, and the inside one of cavity contradicts
Face 541, entirety is in arcuation, corresponding, and the front end of mandril 54, which is formed with, contradicts end 541, contradicts end 541 and 412 phase of resistance surface
It connects and forms certain frictional force between the two, avoid lock tongue 4 that from can arbitrarily rotating relative to push rod 51.
Further, as shown in figure 8, being also formed with spring cavity 413, spring cavity 413 and cavity in the body portion 41 of lock tongue 4
411 are connected, and second spring 6 is equipped in spring cavity 413, and the side of second spring 6 is connected with steel ball 7, steel ball 7 and conflict end
541, which offset, is limited in spring cavity 413, so that, need to be by contradicting end 541 when each lock tongue 4 will rotate and change direction
First steel ball 7 is pressed in meeting spring cavity 413, resistance surface 412 could be moved with respect to end 541 is contradicted, and realize the rotation of lock tongue 4.
Further, as shown in figure 9, being formed with limit end face 542, the first locking surface of lock tongue 4 in the two sides of mandril 54
42 and second locking surface 43 tail end formed stop bit end 44, stop bit end 44 and limit end face 542 between cooperate, when lock tongue 4
When turning to certain angle, stop bit end 44 can be butted on limit end face 542, so that lock tongue 4 can not be rotated further.
As shown in Figure 10, it is also connected on pedestal 1 and locks slide 8, lock the side that slide 8 can be moved along push rod 51
To movement, the lower section locked slide 8 equipped with one piece of top plate 82, and lock slide 8 is equipped with lock core and protrudes into mouth 81, generally in shell
Body is equipped with lock core and protrudes into mouth 81, when user is rotated the shifting block on lock core by the knob in key or door, shifting block
It can squeeze into and lock the lock core of slide 8 and protrude into mouth 81, the top plate 82 locked on slide 8 be withstood on to the tail end of push rod 51, so that lock
Tongue 4 can not be retracted to dead bolt hole 31 when by external force.
Further, as depicted in figs. 11-12, it is equipped with sliding slot 12 on pedestal, locks slide 8 and is equipped with sliding slot 12 relatively
Traveller 83, lock slide 8 by the traveller 83 realize pedestal 1 12 interior orientation of sliding slot move, in addition, being connected on traveller
There is torsional spring, the torsional spring other end is fixed on the pin taken shape on pedestal, so that locking the case where slide 8 is not by external force
Under, so that it is kept existing state by torsional spring 9.
As shown in figure 11, the rear end sides in the body portion 41 are formed with the first stop surface 42 and the second stop surface 43, are locking
When tongue 4 turns to side, the first stop surface 45 can connect with cover board 2, to limit the further rotation of lock tongue 4, opposite, In
On other direction, the second stop surface 46 meeting pedestal 1 connects.
Further, it is equipped with limit closing piece 47 at the position that the first stop surface 42 and the second stop surface 43 connect, locked
The side of slide 8 towards lock tongue 4 be formed with limit jacking block 84, lock slide 8 by top plate 82 push rod 51 is withstood when, thereon
Limit jacking block 84 can also withstand on limit closing piece 47 one end so that lock tongue 4 can not rotate.
Above-described embodiment is only presently preferred embodiments of the present invention, is not limited the scope of the invention according to this, therefore: it is all according to
The equivalence changes that structure of the invention, shape, principle are done, should all be covered by within protection scope of the present invention.
