Abstract
The lock body with double fast functions is characterized in that the linkage plate is provided with an avoidance opening at the right side of the upper end of the lower guide straight groove, the linkage plate is provided with an elastic piece capable of enabling the linkage plate to swing towards the lock cylinder, when people rotate a knob in a house to drive a thumb wheel of the lock cylinder to rotate so as to push a lock tongue assembly to lock a door or open the door, the knob is further rotated slightly so as to enable the thumb wheel to return, even if the thumb wheel can touch the linkage plate, the thumb wheel can act on the linkage plate so as to enable the thumb wheel to swing clockwise by an angle after overcoming the acting force of the elastic piece, and at the moment, the lower guide post slides into the avoidance opening, so that the linkage plate can not prevent the thumb wheel from rotating and returning, and the linkage plate can not lock the lock cylinder; when the pushing of the shifting wheel to the linkage plate is released, the linkage plate can be automatically adjusted, so that the lifting of the linkage plate is not influenced to link the world pin, and the structure of the invention is more reasonable and the use is more reliable.
Description
Technical Field
The invention belongs to a lock body with double quick functions.
Background
It is known that, whether a mechanical lock body or an electronic lock body is provided with a latch assembly, a square tongue assembly, a top-bottom pin, a linkage plate and the like, people push the top-bottom pin out of the lock door or pull back into the shell to open the door through the linkage plate when operating a handle or a key to latch the latch assembly and push out of the lock door or pull back into the shell to open the door. In addition, people can rotate the knob in the house, the knob drives the thumb wheel on the lock core to open and lock the door, once the door opening and the door locking are completed, the knob also needs to be manually rotated to reset the thumb wheel on the lock core, otherwise, when the door is locked or opened at the back, the thumb wheel possibly locks the lock tongue. When the current lock body rotates the thumb wheel to reset, the linkage plate can sometimes block the thumb wheel to influence the reset. To this end, the applicant has improved the current lock body.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide the lock body with the double-quick functions, which has more reasonable structure and more reliable use.
In order to solve the technical problems, the invention adopts the following technical scheme:
a lock body with double quick functions comprises a shell, a lock tongue assembly, a top-bottom pin, a lock cylinder with a thumb wheel and a linkage plate for driving the top-bottom pin to vertically lift, wherein the lock tongue assembly, the top-bottom pin and the lock cylinder with the thumb wheel are arranged in the shell; the lock tongue assembly comprises a lock tongue and a lock tongue plate; the lock cylinder is characterized in that an upper guide straight groove and a lower guide straight groove are formed in the linkage plate, an upper guide column and a lower guide column which respectively penetrate through the upper guide straight groove and the lower guide straight groove are formed in the shell, an avoidance opening is formed in the right side of the upper end of the lower guide straight groove of the linkage plate, and an elastic piece capable of enabling the linkage plate to swing towards the lock cylinder is arranged on the linkage plate.
In an improvement scheme of the lock body with the double-quick function, the elastic piece is a tension spring, and two ends of the elastic piece are respectively connected to the linkage plate and the tongue locking plate.
Compared with the prior art, the invention has the beneficial effects that: because the linkage plate is provided with the avoiding opening on the right side of the upper end of the lower guide straight groove, the linkage plate is provided with the elastic piece which can enable the linkage plate to swing towards the lock cylinder, when people rotate the knob in a house to drive the thumb wheel of the lock cylinder to rotate so as to push the lock tongue assembly to lock the door or open the door, the knob is still further rotated slightly so as to enable the thumb wheel to return, even if the thumb wheel can touch the linkage plate, the thumb wheel can act on the linkage plate so as to slightly swing by an angle clockwise after overcoming the acting force of the elastic piece, and at the moment, the lower guide column slides into the avoiding opening, so that the linkage plate can not prevent the thumb wheel from rotating and returning, and the linkage plate can not lock the lock cylinder; when the pushing of the shifting wheel to the linkage plate is released, the linkage plate can be automatically adjusted, so that the lifting of the linkage plate is not influenced to link the world pin, and the structure of the invention is more reasonable and the use is more reliable.
The invention is described in further detail below with reference to the attached drawings and detailed description:

Fig. 1 is a perspective view (door-open state) of an embodiment of the present invention;
FIG. 2 is a front view of FIG. 1;
FIG. 3 is a front view of an embodiment of the present invention when a lock cylinder is rotated to lock a door;
fig. 4 is a schematic diagram illustrating the assembly and disassembly of the linkage plate according to the embodiment of the present invention.
[ detailed description ] of the invention
1-4, a lock body with double quick functions comprises a shell 1, a lock tongue assembly 2, a top and bottom pin 3, a lock cylinder 4 with a thumb wheel 41 and a linkage plate 5 for driving the top and bottom pin 3 to vertically lift, wherein the lock tongue assembly 2, the top and bottom pin 3 and the lock cylinder 4 with a thumb wheel 41 are arranged in the shell 1; the latch bolt assembly 2 comprises a latch bolt 21 and a latch bolt plate 22; the linkage plate 5 is provided with an upper guide straight groove 51 and a lower guide straight groove 52, the shell 1 is provided with an upper guide post 6 and a lower guide post 7 which respectively penetrate through the upper guide straight groove 51 and the lower guide straight groove 52, and the structures are consistent with the current lock body, and are not described in detail herein, except that: the right side of the upper end of the lower guide straight groove 52 of the linkage plate 5 is provided with a avoidance opening 53, the linkage plate 5 is provided with an elastic piece 8 which can enable the linkage plate 5 to swing towards the lock cylinder 4, when people rotate a knob in a house to drive a thumb wheel 41 of the lock cylinder 4 to rotate to push a lock tongue assembly 2 to lock a door or open the door, the knob is further rotated slightly to enable the thumb wheel to return, even if the thumb wheel can touch the linkage plate, the thumb wheel 41 can act on the linkage plate 5 to enable the thumb wheel to swing clockwise by an angle after overcoming the acting force of the elastic piece 8, and then the lower guide post 7 slides into the avoidance opening 53, so that the linkage plate can not prevent the thumb wheel from rotating to return, and the linkage plate can not lock the lock cylinder; when the pushing of the linkage plate is released by the shifting wheel, the linkage plate 5 is adjusted under the action of the elastic piece, so that the lifting of the linkage plate is not influenced to link the world pin, and the structure of the invention is more reasonable and the use is more reliable.
In this embodiment, the elastic member 8 is a tension spring, and two ends thereof are respectively connected to the linkage plate 5 and the latch plate 22; of course, it may also be a compression spring, torsion spring, etc.
