The utility model content
To the above-mentioned deficiency that exists in the prior art, the utility model provides a kind of more reasonable structure, and the lateral stressed balance of bolt helps parts and installs and change, and also is beneficial to the rolling-gate pick-proof automatic locking on protection ground.
The purpose of the utility model is achieved in that rolling-gate pick-proof automatic locking, comprises the lock frame, is installed in bolt, back-moving spring, lead and the latch hook of the box body of lock on the frame, lock core assembly, the left and right sides; Said lock core assembly is installed in the box body, and an end of the bolt of the left and right sides is connected with the dead bolt of said lock core assembly respectively, and the other end passes the guide pad that lock frame end portion is provided with; On the bolt that is positioned at outside the box body, spring mounting hole is set, it is interior and parallel with the length direction of said bolt that said lead is located at this spring mounting hole; Said back-moving spring is enclosed within on this lead, and an end is pressed on the sidewall of spring mounting hole, and the other end is pressed on the sidewall of said box body.
A kind of preferred version as the utility model also comprises push rod, retainer spring and push rod back-up block; Said push rod back-up block fixedly is located on the bolt near the latch hook inboard, and on the bolt inboard near latch hook, also is provided with the locating slot that push rod withdraws from bolt; Said push rod passes the through hole on the push rod back-up block, and vertical with bolt, and the top bending of push rod becomes 90 °; Said retainer spring is enclosed within on the push rod, and an end is pressed on the push rod back-up block, and the other end is pressed on the fixed stop of push rod bottom setting.
The rolling-gate pick-proof automatic locking of the utility model compared with prior art, has following advantage:
1, the rolling-gate pick-proof automatic locking of the utility model is located at the bolt middle part outside the box body with back-moving spring and lead; Make the bolt lateral balance stressed; It is more easy and convenient to unblank, and the parts in the box body are more reasonable on layout, also is convenient to the installation and the replacing of back-moving spring simultaneously.
2, push rod is installed on the bolt near the latch hook inboard, when closing rolling-gate, the bottom of push rod is on the ground box, does not contact with ground, can not damage ground or damage the ceramic tile of laying on the ground, longer service life.
Description of drawings
Fig. 1 is the structural representation of rolling-gate pick-proof automatic locking.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done to describe in further detail.
Fig. 1 is the structural representation of rolling-gate pick-proof automatic locking, and is as shown in the figure.Rolling-gate pick-proof automatic locking comprises lock frame 1, is installed in bolt 4, back-moving spring 5, lead 6, latch hook 7, push rod 9, retainer spring 10 and the push rod back-up block 11 of the box body 2 of lock on the frame 1, lock core assembly 3, the left and right sides.Lock core assembly 3 is installed in the box body 2, and an end of the bolt 4 of the left and right sides is connected with the dead bolt of said lock core assembly 3 respectively, and the other end passes the guide pad 8 that lock frame 1 end is provided with.On the bolt 4 that is positioned at outside the box body 2, spring mounting hole is set, it is interior and parallel with the length direction of said bolt 4 that lead 6 is located at this spring mounting hole.Back-moving spring 5 is enclosed within on this lead 6, and an end of back-moving spring 5 is pressed on the sidewall of spring mounting hole, and the other end of back-moving spring 5 is pressed on the sidewall of said box body 2.
