Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Example 1: Please refer to Figures 1-8As shown, this utility model provides an inward-sliding, side-opening safe, including a cabinet body 1 and a cabinet door 2. The cabinet door 2 is equipped with a door lock 3 and a bolt linkage assembly 4. The cabinet body 1 has a door frame opening, and a bolt baffle 18 is provided on the side of the door frame opening corresponding to the bolt linkage assembly 4. The cabinet door 2 is mounted on the cabinet body using an eccentric swing shaft. Extended door edges 5 are provided on both sides of the cabinet door 2. Vertically distributed anti-pry door edges 6 are provided on both sides of the door frame opening. The eccentric swing shaft is located on one side of the cabinet door 2. The side of the bolt baffle 18 facing the outside of the cabinet door has a beveled slot 19. When the cabinet door is closed, the extended door edge of the cabinet door 2 adjacent to the bolt baffle 18 is inserted into the beveled slot 19, and the anti-pry door edge 6 covers the outside of the extended door edge 5. The eccentric swing shaft includes a linkage shaft 7, located at both ends of the linkage shaft. The positioning shaft head 8 is installed on the top and bottom plates of the cabinet 1 via fixed bushings (not shown). The positioning shaft head is rotatable within the fixed bushings. The linkage shaft 7 is connected to the positioning shaft head 8 via a swing arm 9. The linkage shaft 7 and the positioning shaft head 8 are staggered to form a crank-type connection structure. The linkage shaft 7 is installed on the cabinet door via a sleeve 17. The linkage shaft 7 is rotatable within the sleeve 17. The sleeve 17 is welded to the cabinet door. A pull tab 10 is fixedly installed in the middle of the linkage shaft 7. The outer end of the pull tab 10 is connected to the door lock handle via a connecting rod 11. Rotating the door lock handle moves the connecting rod 11, which pulls the pull tab 10. Under the action of the crank-type connection structure, the pull tab 10 drives the linkage shaft 7 to swing, thereby driving the cabinet door 2 to move to the side rear or side front via the linkage shaft 7. The anti-pry door edge 6 is inclined towards the inside of the cabinet, and the outer door edge 5 is inclined towards the outside of the cabinet. The inclined surface of the inclined slot 19 is consistent with the inclined direction of the outer door edge 5. Both the upper and lower sides of the door frame opening are provided with door edge baffles 12, and the door edge 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 edge baffles are provided with cabinet door inward displacement notches 16 at the end near the eccentric swing shaft. The outer end of the pull tab 10 is connected to the connecting rod 11 by a ball head bushing 15.
[0023] The operating principle of this utility model is as follows: When opening the door, first turn the door lock handle. The door lock handle drives the connecting rod 11 to move. The connecting rod 11 pulls the pull plate 10. Under the action of the crank-type connection structure of the eccentric swing shaft, the pull plate 10 drives the linkage shaft 7 to swing. Then, through the linkage shaft 7, the cabinet door 2 moves parallel to the right rear, so that the anti-pry door edge 6 no longer blocks the outer edge 5. The bolt linkage component 4 moves synchronously with the cabinet door and disengages from the door frame. The U-shaped pin 14 disengages from the pin opening 13. At this time, pull the door lock handle outward, causing the cabinet door 2 to rotate to the side around the positioning shaft head 8. When the cabinet door rotates, the side closer to the eccentric swing shaft will gradually enter the cabinet body, and the side with the bolt linkage component 4 will gradually flip out of 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, the first person flips the cabinet door to a position parallel to the door edge baffle 12, then turns the door lock handle. This causes the linkage shaft 7 to swing via the connecting rod 11 and the pull plate 10, moving the cabinet door to the left and forward. The U-shaped bolt 14 gradually inserts into the bolt slot 13, and the bolt linkage assembly 4 engages inside the bolt baffle 18. The outer door edge 5 moves completely into the coverage area of the anti-pry door edge 6. The outer door edge 5 near the bolt linkage assembly 4 inserts into the inclined slot on the outside of the bolt baffle 18 along its own tilt angle, completing the closing action of the cabinet door. The bolt baffle 18 can limit the outer door edge 5 on one side of the cabinet door. In addition, when the door lock 3 is not open, the bolt handle cannot be turned, and the eccentric swing shaft will not swing. The eccentric swing shaft limits the other side of the cabinet door, preventing the cabinet door from moving inward. The anti-pry door edge covers the outer side of the extended door edge, achieving a fully covered and concealed design of the gaps on both sides of the cabinet door, improving the anti-pry effect of the cabinet door. The cabinet door cannot be opened outwards unless it moves to the side and rear, thus enhancing the anti-theft performance of the safe. This utility model allows for multiple actions simultaneously—opening the bolt and moving the cabinet door to the side and rear—with a single turn of the door lock handle, making operation simple and convenient. The anti-pry door edge of this utility model is inclined inwards towards the cabinet body, and the extended door edge is inclined outwards towards the cabinet body, preventing the insertion of prying tools and further improving the anti-pry effect of the cabinet door.
[0024] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
