[0028] After some safe doors are opened, if the safe door bolt is in the open state and the door is not closed, it will cause the bolt to collide with the door frame, which will cause damage to the bolt. Therefore, it is necessary to improve the existing technology to solve the shortcomings of the existing technology. Figures 1 to 3 The utility model provides a safe door bolt anti-collision device and a safe door, and makes the following embodiments:

[0029] In some embodiments, a safe door bolt anti-collision device includes a mounting plate 100, a bolt movable component, and an anti-collision structure. The mounting plate 100 is used to mount the bolt movable component and the anti-collision structure, which can be a separate plate, which is mounted on the safe door when in use, or can be a part of the door panel of the safe door; the bolt movable component is the door lock part; the anti-collision structure prevents the bolt from colliding with the door frame, and plays a role in protecting the bolt.

[0030] The bolt movable assembly includes two bolt rods 210, the bolt rods 210 are extended left and right, the bolt rods 210 are connected with sliding pieces 360, the two sliding pieces 360 are arranged on the same connecting plate, the connecting plate is extended up and down, the mounting plate 100 is provided with four positioning columns 110, each sliding piece 360 ​​is provided with two guide holes, the guide holes are slidably sleeved on the positioning columns 110, the guide holes are extended left and right, the bolt rod 210 and the sliding piece 360 ​​slide left and right as a whole, and the left and right sliding is the sliding direction of the bolt rod 210, so the bolt rod 210 extends when sliding to the left, and retracts when sliding to the right. In some other embodiments, the number of the bolt rods 210 can be one or more, which is actually set according to the specific situation.

[0031] The anti-collision structure includes a hook plate 310, a top rod 320, a bracket 330, and a stopper 350. The stopper 350 is arranged at the right end of a sliding sheet 360. The hook plate 310 is rotatably arranged on the mounting plate 100. The hook plate 310 is movably connected to the top rod 320. The hook plate 310 is provided with a waist-shaped hole 311. The top rod 320 is provided with a connecting block 321, and the connecting block 321 is sleeved in the waist-shaped hole 311. As the top rod 320 slides left and right, the hook plate 310 rotates accordingly. The stopper 350 can be arranged on any one of the sliding sheets 360, and is specifically arranged according to other structures of the safe door. Of course, multiple anti-collision structures can also be provided to improve the anti-collision capability.

[0032] The bracket 330 is arranged on the mounting plate 100, and the bracket 330 is provided with two support plates arranged at intervals, the push rod 320 is slidably sleeved on the two support plates, the push rod 320 is provided with abutment blocks 322, and the elastic member is arranged between the abutment blocks 322 and one of the support plates. The push rod 320 extends out of the door and abuts against the door frame, and an elastic member is arranged between the push rod 320 and the bracket 330, and the elastic member provides elastic force for the push rod 320 to move so that the hook portion of the hook plate 310 is engaged with the stopper 350.

[0033] The elastic member includes a spring 340, which is sleeved on the top rod 320, and the two ends of the spring 340 are respectively on the left support plate and the abutment block 322. In this embodiment, the abutment block 322 is an abutment rod provided on the top rod 320, and in some other embodiments, the abutment block 322 is an annular step provided on the top rod 320.

[0034] In some other embodiments, the elastic member may also be an elastic member such as an elastic sheet.

[0035] After the safe door is opened, the push rod 320 lacks the contact with the door frame. The push rod 320 extends outward under the elastic force of the elastic member, driving the hook plate 310 to rotate, hooking the block 350, and the bolt rod 210 retracts into the door. At this time, when the door is closed, the bolt rod 210 will not hit the door frame to cause damage to the bolt rod 210. When the safe door is closed back into the door frame, the push rod 320 is contacted by the door frame, the push rod 320 moves, the hook plate 310 rotates and no longer hooks the block 350, and the bolt rod 210 extends outward to lock the safe door. The utility model plays a good role in protecting the bolt and has a simple structure. It should be noted that after the safe door is opened, the push rod 320 rotates accordingly with the safe door, but still contacts the door frame. Therefore, after the safe door is closed, the push rod 320 moves further to the left under the action of the door frame, releases the block, and the bolt rod 210 can be freely extended and retracted.

[0036] Furthermore, the bolt movable assembly includes a driving mechanism for driving the bolt rod 210 to move, generally including a rotating handle, a gear plate 410, and a rack 420, wherein the rack 420 is arranged on the sliding sheet 360, the rack 420 is arranged on the bolt rod 210, and the rotating handle is arranged on the gear plate 410. The rotating handle drives the bolt rod 210 to move and locks the vault door. The rotating handle is located at one end of the bolt body, so that people can hold the bolt body to open and close the door.

[0037] In some other embodiments, the pushing mechanism includes a longitudinal pushing rod and a transverse pushing block. The transverse pushing block can rotate around the pin shaft and has a pushing rod extending therefrom, which is movably connected to the longitudinal pushing rod. A roller is provided at the other end of the longitudinal pushing rod, which contacts the bottom of the slider to push the sliding bolt movable component to slide in the bolt seat. A lock body can also be provided: the core component of the bolt lock, which controls the opening and closing of the bolt by means of a key or a handle. Common types of lock bodies include cylindrical lock bodies and panel lock bodies.

[0038] The utility model also provides an embodiment of a safe door, including a safe door bolt anti-collision device as described in any one of the above items, which is installed inside the safe door. When the safe door is opened, the push rod 320 extends from the safe door under the action of the spring 340, and the door frame does not abut the push rod 320. The hook plate 310 hooks the block 350 on the sliding sheet 360 under the action of the push rod 320, and the bolt rod 210 does not extend. When the safe door is closed, the push rod 320 is abutted by the door frame, and the hook plate 310 rotates upward under the push of the push rod 320, and no longer hooks the block 350, and the bolt rod 210 extends smoothly to lock the safe door. Of course, the extension and retraction of the bolt rod 210 can be controlled by a pushing mechanism that controls the extension and retraction of the bolt rod 210. For example, the bolt rod 210 is driven to move by a toggle method, and the bolt rod 210 is further driven to move by rotating the handle.

[0039] Due to the anti-collision device, the bolt of the safe door will not be extended until the safe door enters the door frame, and the bolt is not easy to be damaged. It should be noted that the utility model is mainly applied to safe doors, but is not limited to safe doors, and can also be applied to other doors locked by bolt structures, such as warehouse doors.

[0040] The preferred implementation modes of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
