Description

A kind of glass door lock

Technical field

The utility model relates to a kind of door lock, is specifically related to a kind of glass door lock.

Background technology

Door lock is an equipment indispensable in the social life now.At present, general glass door lock great majority are to carry out switch by the gear fit form on market, thereby realization is unblanked, the function of locking.This kind glass door lock utilizes the terminal control of lock core transmitting gear, and the dead bolt that has tooth hole hole clipping fiddles with, so will cause lock body stuck in case there is foreign matter to enter tooth hole hole clipping; And dead bolt is designed to 180 ° of switchings because transmitting gear is designed to 360 ° of switchings, the reason that gear ratio there are differences, if the punching press gear piece slight error or transmitting gear occur and produces in daily continual open and close with tooth hole hole clipping and wear and tear, dead bolt is easy to the phenomenon that occurs getting stuck.

The utility model content

In order to solve the deficiencies in the prior art, the purpose of this utility model be to provide a kind of need to rotate 180 ° of easy operations, the novel glass door lock of the phenomenon that can not occur getting stuck.

For achieving the above object, the technical scheme that the utility model adopted is as follows:

A kind of glass door lock comprises main lock body, auxiliary lock body and is positioned at lock core and knob on the main lock body that main lock body inside is provided with the dead bolt that connects lock core, and dead bolt is connected an end of tongue switching plate; Described dead bolt is the arc bolt, and described main lock body is provided with dead bolt hole, also is provided with dead bolt hole with main lock body position adjacent place on the described auxiliary lock body, and main lock body inside is provided with the limiting plate of restriction dead bolt scope of activities.

Described main lock body comprises procapsid and back casing, respectively is provided with a dead bolt and a dead bolt portable plate in described procapsid and the back casing, and lock core is fixed on the procapsid of main lock body, and knob is fixed on the back casing of main lock body; Auxiliary lock body comprises procapsid and back casing, and back casing and procapsid have an arc dead bolt passage between two dead bolt holes.

In the utility model, the tongue switching plate that connects with dead bolt is provided with and the consistent lock core hole of lock core shape, and the tail end of lock core is outstanding from lock core hole; The tongue switching plate that connects with knob is provided with the knob hole consistent with knob shaped, and the tail end of knob is outstanding from knob hole.

In the preferred scheme of the utility model, the procapsid of described main lock body and back casing respectively are provided with two dead bolt holes respectively; The procapsid of described auxiliary lock body and back casing also respectively are provided with two dead bolt holes respectively.

Preferably, lock core described in the utility model and knob all tighten up fixing by screw.

Preferably, described bolt plate is by tensioning screw or directly be weldingly fixed on the arc dead bolt.

Compared to existing technology, the beneficial effects of the utility model are: the utility model has utilized body mechanics's principle well, come the rotating lock tongue swinging plate for 180 ° by key turns, make the arc dead bolt that is fixed on the tongue switching plate carry out corresponding 180 ° of slips, realized the function of lock body opening and closing quickly and easily, the phenomenon that gets stuck of meshing form can not occur, thereby stop wearing and tearing used in everyday and damage, further prolong the application life of glass door lock.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 5, glass door lock of the present utility model comprises main lock body 1, auxiliary lock body 2 and is positioned at lock core 11 and knob 14 on the main lock body 1, main lock body 1 inside is provided with the dead bolt 15 that connects lock core 11, and dead bolt 15 is connected an end of tongue switching plate 16; Described dead bolt 15 is the arc bolt, and described main lock body 1 is provided with dead bolt hole, also is provided with dead bolt hole with main lock body 1 position adjacent place on the described auxiliary lock body 2, and main lock body 1 inside is provided with the limiting plate 18 of restriction dead bolt 15 scopes of activities; Described main lock body 1 comprises procapsid 12 and back casing 13, respectively is provided with a dead bolt and a dead bolt portable plate in described procapsid 12 and the back casing 13, and lock core 15 is fixed on the procapsid of main lock body 1, and knob 14 is fixed on the back casing of main lock body 1; Auxiliary lock body 2 comprises procapsid 22 and back casing 23, and back casing 23 and procapsid 22 have an arc dead bolt passage between two dead bolt holes; The tongue switching plate that connects with dead bolt 15 is provided with and the consistent lock core hole of lock core shape, and the tail end of lock core is outstanding from lock core hole; The tongue switching plate that connects with knob is provided with the knob hole consistent with knob shaped, and the tail end of knob is outstanding from knob hole.。

As shown in Figure 4, when the user inserts key and stirs lock core 11 and carry out locking, driving the lock core afterbody slides, because tongue switching plate 16 is provided with the through hole consistent with the lock core tail shape, thereby the direction activity that the arc dead bolt 15 that is fixed on the tongue switching plate 16 is started to key, arc dead bolt 15 passes the dead bolt hole 17 on the main lock body procapsid earlier, then enters the dead bolt hole 21 on the auxiliary lock body procapsid, pass by dead bolt hole 24 again, get back to the main dead bolt hole of locking 19 at last.Like this, 180 ° of key turns, just can realize the closure of arc dead bolt 15, with main lock body 1 and auxiliary lock body 2 secure lock, thereby make two glass doors split of fan locked closed safely, effective simplification the meshing structure of general 360 ° of rotations of lock core on the present market, greatly facilitate user's operation.

When the user need turn knob 14 when carrying out locking, the afterbody that rotates knob by hand slides, because the tongue switching plate is provided with the fixed hole position consistent with the knob tail shape, when knob 14 afterbodys rotate, the tongue switching plate is along with knob, driving the arc dead bolt that is fixed on the tongue switching plate simultaneously does along with the direction that the tongue switching plate rotates is done corresponding motion, dead bolt passes the dead bolt hole on the main lock body back casing earlier, two dead bolt holes that then successively enter the auxiliary lock body back casing pass the back casing of auxiliary lock body, another dead bolt hole from the main lock body back casing is got back in the main lock body at last, realizes the locking function.Like this, need only 180 ° of knob, just can realize the closure of dead bolt, main lock body 1 and auxiliary lock body 2 are locked fully, thereby make that the glass full locks of two fans are fixed closed, and because the effect of limiting plate, dead bolt the phenomenon that gets stuck can not occur in the process of whole motion.

Same principle, user's reverse operating lock core or knob can be opened lock body, open glass door.

In the preferred scheme of the utility model, the procapsid of described described main lock body and back casing respectively are provided with two dead bolt holes respectively; The procapsid of described auxiliary lock body and back casing also respectively are provided with two dead bolt holes respectively, and described dead bolt is two, fastness and safety that can the reinforced glass door lock.

Preferably, described lock core of the present utility model and knob all tighten up fixing by screw, and described bolt plate is by tensioning screw or directly be weldingly fixed on the arc dead bolt.

Above-mentioned true mode only is a preferred implementation of the present utility model; can not regard restriction as to the utility model protection domain; the distortion and the replacement of any unsubstantiality that those skilled in the art is done on basis of the present utility model all belong to protection domain of the present utility model.
