Description

Technical Field

[0001] The present invention relates to the technical field of anti-theft equipment, in particular to a safe with an inner side sliding and side opening door. Background Art

[0002] The doors of existing safes are mostly side-opening. When the side-opening door is opened, the door leaf flips directly outward from the cabinet body. To facilitate the side-opening of the door, the cabinet body cannot block the door. A gap must be reserved between the door and the cabinet body. This gap can easily be exploited by illegal personnel to insert prying tools and damage the door, posing a significant safety hazard. Therefore, it is necessary to provide a new safe to solve the above technical problems. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a safe with an inner side sliding and side opening door, which has the advantages of good anti-pry and sealing effects, simple structure and easy use.

[0004] The present invention adopts the following technical scheme: an inward-moving and side-opening door safe, comprising a cabinet body and a cabinet door, the cabinet door being provided with a door lock and a lock bolt linkage assembly, the cabinet body being provided with a door frame opening, and the side of the door frame opening corresponding to the lock bolt linkage assembly being provided with a lock bolt baffle, characterized in that: the cabinet door is mounted on the cabinet body by an eccentric swing shaft, and both sides of the cabinet door are provided with extended door edges; both sides of the door frame opening are provided with vertically distributed anti-theft door edges, the eccentric swing shaft is located on one side of the cabinet door, and the side of the lock bolt baffle facing the outside of the cabinet door is provided with an inclined slot, and when the cabinet door is closed, the extended door edge of the cabinet door adjacent to the lock bolt baffle is inserted into the inclined slot, and the anti-theft door edge is covered on the outside of the extended door edge; the eccentric swing shaft The shaft includes a linkage shaft and positioning shaft heads located at both ends of the linkage shaft; the positioning shaft heads are respectively installed on the top plate and the bottom plate of the cabinet through fixed shaft sleeves, and the positioning shaft heads can rotate in the fixed shaft sleeves; the linkage shaft and the positioning shaft heads are connected by a swing arm, and the linkage shaft and the positioning shaft heads are staggered to form a crank-type connection structure; the linkage shaft is installed on the cabinet door through a sleeve, and the linkage shaft can rotate in the sleeve. A fixed pull tab is provided in the middle of the linkage shaft, and the outer end of the pull tab is connected to the door lock handle through a connecting rod; rotating the door lock handle drives the connecting rod to move, and the connecting rod pulls the pull tab. Under the action of the above-mentioned crank-type connection structure, the pull tab drives the linkage shaft to swing, and then drives the cabinet door to move to the side rear or side front through the linkage shaft.

[0005] Furthermore, the anti-theft door edge is inclined toward the inner side of the cabinet, the extended door edge is inclined toward the outer side of the cabinet, and the inclined surface of the inclined slot is consistent with the inclined direction of the extended door edge.

[0006] Furthermore, door side baffles are provided on the upper and lower sides of the door frame opening, and latch openings are provided on the door side baffles. U-shaped latches corresponding to the latch openings are provided on the upper and lower sides of the inner side of the cabinet door, and a notch for inward movement of the cabinet door is provided on the door side baffle near one end of the eccentric swing shaft.

[0007] Furthermore, the outer end of the pull tab is connected to the connecting rod by a ball head sleeve.

[0008] The present invention has the following beneficial effects: The present invention utilizes the anti-theft door edge to cover the outer side of the extended door edge, thereby realizing a fully covered and hidden design of the gaps on both sides of the cabinet door, thereby improving the anti-theft effect of the cabinet door. When the cabinet door does not move to the side and rear, the cabinet door cannot be opened outward, thereby improving the anti-theft performance of the safe.

[0009] The present invention utilizes an eccentric swing shaft linked to the door lock handle. To open the door, first rotate the door lock handle. This eccentric swing shaft drives the entire cabinet door to move laterally and rearward, so that the anti-theft door edge no longer covers the extended door edge. The lock bolt linkage assembly disengages from the door frame opening. The door lock handle is then pulled outward, causing the cabinet door to rotate laterally around the positioning shaft head, thereby opening the cabinet door. To close the cabinet door, simply reverse these steps. A single rotation of the door lock handle simultaneously achieves multiple actions: opening the lock bolt and moving the cabinet door laterally and rearward. This is simple and convenient to operate.

[0010] The anti-theft door edge of the present invention is inclined toward the inner side of the cabinet body, and the extended door edge is inclined toward the outer side of the cabinet body, so that tools for prying the door cannot be inserted, thereby further improving the anti-theft effect of the cabinet door.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] Example 1: Please refer to Figures 1-8As shown, the present invention provides an inside-moving and side-opening door safe, comprising a cabinet body 1 and a cabinet door 2, the cabinet door 2 being provided with a door lock 3 and a lock bolt linkage assembly 4, the cabinet body 1 being provided with a door frame opening, and a lock bolt baffle 18 being provided on the side of the door frame opening corresponding to the lock bolt linkage assembly 4, the cabinet door 2 being mounted on the cabinet body by an eccentric swing shaft, and both sides of the cabinet door 2 being provided with an extended door edge 5; both sides of the door frame opening being provided with a vertically distributed anti-theft door edge 6, the eccentric swing shaft being located on one side of the cabinet door 2, and a side of the lock bolt baffle 18 facing the outside of the cabinet door being provided with an inclined slot 19, when the cabinet door is closed, the extended door edge of the cabinet door 2 adjacent to the lock bolt baffle 18 is inserted into the inclined slot 19, and the anti-theft door edge 6 is covered on the outside of the extended door edge 5; the eccentric swing shaft comprising a linkage shaft 7, a linkage shaft located at both ends of the linkage shaft Positioning shaft head 8; the positioning shaft head 8 is respectively mounted on the top and bottom plates of the cabinet body 1 via fixed sleeves (not shown), and the positioning shaft head 8 is rotatable within the fixed sleeves. The linkage shaft 7 is connected to the positioning shaft head 8 by a swing arm 9, and the linkage shaft 7 and the positioning shaft head 8 are staggered to form a crank-type connection structure. The linkage shaft 7 is mounted on the cabinet door via a sleeve 17, and the linkage shaft 7 is rotatable within the sleeve 17. The sleeve 17 is welded to the cabinet door. A fixed pull tab 10 is provided in the middle of the linkage shaft 7, and the outer end of the pull tab 10 is connected to the door lock handle via a connecting rod 11. Turning the door lock handle drives the connecting rod 11 to move, and the connecting rod pulls the pull tab 10. Under the action of the above-mentioned crank-type connection structure, the pull tab 10 drives the linkage shaft 7 to swing, and then drives the cabinet door 2 to the side and rear or side and front through the linkage shaft 7. The anti-theft door edge 6 is inclined toward the inside of the cabinet body, and the extended door edge 5 is inclined toward the outside of the cabinet body. The inclined surface of the inclined slot 19 is consistent with the inclination direction of the extended door edge 5. The upper and lower sides of the door frame opening are provided with door side baffles 12, and the door side baffles 12 are provided with latch holes 13. The upper and lower sides of the inner side of the cabinet door are provided with U-shaped latches 14 corresponding to the latch holes. The door side baffle is provided with a notch 16 for inward movement of the cabinet door at one end near the eccentric swing axis; the outer end of the pull tab 10 is connected to the connecting rod 11 by a ball head shaft sleeve 15.

[0022] The operating principle of the present invention is as follows: when opening the door, first rotate the door lock handle, the door lock handle drives the connecting rod 11 to move, and the connecting rod 11 pulls the pull tab 10. Under the action of the crank-type connection structure of the eccentric swing shaft, the pull tab 10 drives the linkage shaft 7 to swing, and then drives the cabinet door 2 to move parallel to the right rear through the linkage shaft 7, so that the anti-theft door edge 6 no longer forms an obstacle to the outward extended door edge 5. The lock bolt linkage assembly 4 moves synchronously with the cabinet door to disengage from the door frame opening, and the U-shaped pin 14 disengages from the pin opening 13. At this time, pull the door lock handle outward again, driving the cabinet door 2 to rotate sideways with the positioning shaft head 8 as the axis center. When the cabinet door rotates, the side close to the eccentric swing shaft will gradually enter the cabinet body, and the side where the lock bolt linkage assembly 4 is installed will gradually flip outside the cabinet body. When the cabinet door rotates 90 degrees and is parallel to the side of the cabinet body, the cabinet door opening action is completed. When closing the cabinet door, first flip the cabinet door to a position parallel to the door edge baffle 12, then turn the door lock handle, which drives the linkage shaft 7 to swing through the connecting rod 11 and the pull tab 10, causing the cabinet door to move to the left and front. The U-shaped latch 14 is gradually inserted into the latch opening 13, and the lock linkage assembly 4 is snapped into the inner side of the lock baffle 18. The extended door edge 5 is completely moved into the coverage range of the anti-theft door edge 6. The extended door edge 5 close to the lock linkage assembly 4 is inserted into the inclined slot on the outside of the lock baffle 18 along its own tilt angle, completing the closing of the cabinet door. The lock baffle 18 can form a limit for the extended door edge 5 on one side of the cabinet door. In addition, when the door lock 3 is not opened, the lock handle cannot be rotated, and the eccentric swing shaft will not swing. The eccentric swing shaft forms a limit for the other side of the cabinet door, preventing the cabinet door from moving inward. The anti-pry door edge is wrapped around the outside of the extended door edge, achieving a fully covered and concealed design for the gaps on both sides of the cabinet door, thereby improving the cabinet door's anti-pry effect. Without moving the cabinet door to the side and rear, the cabinet door cannot be opened outward, thereby improving the safe's anti-theft performance. A single turn of the door lock handle of the present invention can simultaneously achieve multiple actions: opening the lock bolt and moving the cabinet door to the side and rear, making it simple to operate and easy to use. The anti-pry door edge of the present invention is tilted toward the inside of the cabinet body, and the extended door edge is tilted toward the outside of the cabinet body, making it impossible to insert prying tools, further improving the cabinet door's anti-pry effect.

[0023] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
