Detailed Description
The invention will be further described with reference to specific embodiments below:
the first embodiment is as follows:
referring to fig. 1-2, fig. 1 is a schematic structural diagram of a normal state in this embodiment, at this time, the door lock belongs to a locked state, and the top-rod hook 2 and the bottom-rod hook 3 are both unfolded outwards, so that the top-bolt and the bottom-bolt mounted on the top-rod hook 2 and the bottom-rod hook 3 are respectively clamped in the bolt grooves above and below the door frame, and locking is completed.
The structure of bolt lock includes lock body 1 as the main lock frame, and day pole drag hook 2 and ground pole drag hook 3 set up in lock body 1 to can be in 1 interior up-and-down motion of lock body, be provided with linkage 4 between day pole drag hook 2 and the ground pole drag hook 3, the middle part of linkage 4 articulates on lock body 1, both ends are connected respectively on day pole drag hook 2 and ground pole pull rod, when day pole drag hook 2 or ground pole drag hook 3 to the lateral motion, linkage 4 can drive another drag hook to opposite direction motion.
The inside actuating mechanism 5 that is used for driving day pole drag hook 2 motion that still has of lock body 1, actuating mechanism 5's structure is actuating spanner 16, driving piece 17 and drive transmission piece 18, the middle part of drive transmission piece 18 articulates on lock body 1, make it rotate around the pin joint, the both ends of drive transmission piece are connected respectively in day pole drag hook 2 and driving piece 17, driving piece 17 is connected with actuating spanner 16, it can link driving piece 17 and move together to rotate actuating spanner 16 simultaneously, the drive head 19 of driving piece 17 front end promotes the one end of drive transmission piece 18, drive through drive transmission piece 18 makes day pole drag hook 2 downstream, and simultaneously, drive ground pole drag hook 3 upward movement, and will install day lock tongue and ground lock tongue on day pole drag hook 2 and ground pole drag hook 3 and withdraw from the lock tongue groove, accomplish the unblock and open the door.
The utility model discloses a design point mainly lies in installing self-locking structure in lock body 1, drive spanner 16 is loosened after the lock is opened to the bolt lock that does not have self-locking structure often, there is the spring to reset lock door state (initial condition) with day pole drag hook 2 and ground pole drag hook 3, day spring bolt and ground spring bolt expand to both sides, this moment, because the height that highly can be higher than the spring bolt groove on ground, ground spring bolt can sustained contact to ground, use after a period, the floor can be harmd to the spring bolt, but also can produce frictional noise.
The utility model provides a from lock structure embodiment one includes screens 6 and release lockpin 7, and the middle part of screens 6 articulates in lock body 1, and screens 6 can rotate around the pin joint, and screens groove 8 has been seted up to the front end of screens 6, be provided with on the ground pole drag hook 3 with the screens round pin 9 of 8 looks adaptations in screens groove, the pin joint of screens 6 still overlaps and has a torsional spring, and the one end of torsional spring is connected on the ground pole pull rod, and the other end is connected on screens 6.
The working principle is as follows: specifically, as shown in fig. 7-8, fig. 7 is a structural diagram of the self-locking mechanism in the door locking state, and fig. 8 is a structural diagram of the self-locking mechanism in the unlocking state, when a user opens the door, the user presses down the driving wrench 16, drives the ground rod retractor 3 to move upwards through the middle connecting component, and when the ground rod retractor 3 moves, the torsion spring drives the clamping member 6 to rotate around the hinge point, so that the clamping groove 8 on the clamping member 6 gradually approaches the clamping pin 9 on the ground rod retractor 3, and when the driving wrench 16 is pressed down in place, the clamping pin 9 is clamped in the clamping groove 8, so that the resetting of the ground rod retractor 3 is limited, and therefore, after the door lock is opened, the self-locking mechanism can automatically lock the ground rod retractor 3 to prevent the resetting of the ground rod retractor, and the problem that; the unlocking pin 7 is arranged on the side edge of the lock body 1, one end of the unlocking pin extends out of the lock body 1, and the other end of the unlocking pin is positioned at the unlocking part 10 at the rear end of the clamping part 6. When the ground rod unlocking mechanism is used (see figure 8), the unlocking pin 7 is pushed from outside to inside, the unlocking part 10 is pushed by the rear end of the unlocking pin 7, the clamping groove 8 in the clamping part 6 is enabled to be withdrawn from the ground rod drag hook 3, and the reset spring 15 is arranged between the top rod drag hook 2 and the lock body 1, so that the ground rod drag hook 3 can automatically reset to an initial state when the limitation of the clamping part 6 is lost, and the door is locked, so that the use is convenient, and unnecessary operation is not needed.
The front end of the unlocking pin 7 is provided with a guide part which is arc-shaped, when the door is closed, the guide part at the front end of the unlocking pin 7 contacts the door frame, the unlocking pin 7 is naturally pushed through the inertia of the door to complete unlocking and lock the door, and the process is simple and convenient.
Example two:
the other two implementation principles are the same as the first implementation principle, and the difference is only in a self-locking structure, specifically see fig. 4-6 and 9-12, the self-locking mechanism in the second implementation example includes a locking member 20, a locking block 21, a releasing pin 7, and a return spring 15 disposed between the lock body 1 and the locking block 21, the locking member 20 is fixed on the ground rod draw hook 3, the locking member 20 moves along with the movement of the ground rod draw hook 3, the movement direction of the locking block 21 is perpendicular to the movement direction of the locking member 20, a guide port 22 is disposed in the middle of the locking member 20, a limit groove 23 is further disposed in the guide port 22, a limit pin 24 is formed on the locking block 21, and the limit pin 24 is located in the guide port 22,
the working principle is as follows: the user is when opening the door, pushes down drive spanner 16, drives ground pole drag hook 3 up-wards movement through middle coupling assembling, and when ground pole drag hook 3 moved, drive locking piece 20 downstream, when pushing down to a locating position, locking piece 21 blocked spacing pin 24 on it to spacing groove 23 (see fig. 10) through reset spring 15 to restricted reset of ground pole drag hook 3, consequently after opening the lock, self-locking mechanism can pin ground pole drag hook 3 automatically, prevents it and resets. The way of releasing the detent 7 is similar to the embodiment.
The above-mentioned embodiment is only the preferred embodiment of the present invention, and does not limit the protection scope of the present invention according to this, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
