Abstract
The utility model discloses a device for locking a bicycle or a bike, which resists strong impact. The fastening point of the front end of a bolt and a groove of the end of a lock beam is made into an inclined plane, the included angle of the inclined plane and the axial line of the bolt is larger than 8 DEG and smaller than 25 DEG, and the bolt and the lock beam are interlocked with each other. The resistance of the utility model exceeds the self inertial mass of the bolt, and the utility model can effectively resist illegal unlocking caused by strong impact.
Description
The utility model belongs to the technical field of lock.
In the prior art, be used for motorcycle, the convertible lock of the casting lock body of bicycle etc., the lock mode of closing of big padlock are after the lock bridge termination enters hole of button, and the door bolt gyrus lingulais that promotes in the lock body cross-drilled hole is contracted, when the groove of lock bridge termination was relative with the door bolt tongue, the door bolt tongue was promoted to enter groove by spring and is interlocked.Its shortcoming is: when lock body is subjected to when fastening the axially consistent brute force impact of tongue with a bolt or latch, the inertia mass of door bolt tongue will overcome spring force and return dropout, and lock is illegally opened, if increase spring force, then make and close when lock lock bridge termination and enter the resistance that keyhole promotes the door bolt tongue and increase greatly, cause and use inconvenience.
The purpose of this utility model is that a kind of spring force and anti-powerful locking system that impacts of must not increasing will be provided.
The utility model is realized by the following technical solutions: the inclined-plane of ganging up with is mutually made at the fastening place of door bolt tongue front end and lock bridge end groove, and this inclined-plane is spent, is spent less than 25 greater than 8 with the angle of door bolt tongue axis.When lock body was subjected to powerful the impact, door bolt tongue and lock bridge can move toward the direction of unblanking to thread off simultaneously, because the inclined-plane that door bolt tongue and lock bridge end groove are ganged up with mutually forms interlocking, the resistance that the door bolt tongue is moved substantially exceeds its inertia mass, and lock can not be opened.
The advantage that the utility model compared with prior art has is, under the prerequisite that does not increase part and cost, the inclined-plane that the plane contact at door bolt tongue and lock bridge fastening place is made into to gang up with mutually and form interlocking has improved the impact resistance of locking greatly.
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is a sectional view of the present utility model.
Fig. 2 is the lock bridge partial sectional view of embodiment 2.
Spring (1) and door bolt tongue (3) are loaded on left end, the lock core (2) of the cross-drilled hole (6) of lock body (8) top and place restrictions on the stroke that door bolt tongue (3) moves right, and the eccentric rotary of lock core (2) moves to left door bolt tongue (3) and unblanks.The termination of closing when lock lock bridge (5) enters keyhole (7) back, promote door bolt tongue (3) moves to left, when the groove of lock bridge (5) end is relative with door bolt tongue (3), bullet Huang (1) promotion fastens the groove that tongue (3) enters lock bridge (5) end with a bolt or latch.The inclined-plane (4) of ganging up with is mutually made at the below of door bolt tongue (3) end and the fastening place of lock bridge (5) end recesses, and this inclined-plane is spent, spent less than 25 greater than 8 with the angle of door bolt tongue axis.Embodiment 2 makes and fastens with a bolt or latch the annular groove (9) that tongue (3) end chamfer is ganged up with mutually with the groove of lock bridge end.When lock body (8) is subjected to the brute force axially consistent with fastening tongue (3) with a bolt or latch and impacts, door bolt tongue (3) is because of effect of inertia will be moved to the left, lock bridge (5) also moves up, intersects because of both directions of motion become 90 degree simultaneously, the inclined-plane at its fastening place (4) just forms interlocking, and the resistance of generation is highly resistant to brute force illegally unblanking when impacting.
Claims (2)
1. locking system by lock body with place lock bridge, spring, door bolt tongue and lock core in the lock body to form, is characterized in that: the fastening place beveling of door bolt tongue front end and lock bridge end recesses, this inclined-plane is spent, is spent less than 25 greater than 8 with the angle of door bolt tongue axis.
2. a kind of locking system according to claim 1 is characterized in that the inclined plane groove of lock bridge end both can be made breach shape, also can make annular groove.
