Background Art

[0002] In the existing technology, coins have the advantages of being easy to use, wear-resistant, and having a long circulation life. In order to meet the needs of various self-service devices such as coin ticket purchase, safe and convenient coin circulation, recycling and turnover, etc., coin recycling boxes are one of the necessary devices. At present, general coin recycling boxes do not have a safety function. When operators take them out of the cabinet and go to the management office, they can easily touch the coins, which brings loopholes to revenue management. There is also a coin recycling box with a double lock safety design, but because the box structure and linkage mechanism design are relatively complicated, the lock machine takes up a lot of space, which seriously reduces the effective volume of the box. Based on the above two reasons, it is very necessary to develop a set of coin recycling box door locks with a simple structure and a safety function. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the defects existing in the above-mentioned prior art and provide a coin recovery box door lock device, which aims to solve the problem of the coin recovery box obtaining a safety function while adopting a compact linkage structure to reduce the space occupied by the lock machine and improve the effective utilization rate of the box volume.

[0004] The present invention adopts the following technical solutions to solve its technical problems: a coin collection box door lock device, comprising a cover body capable of accommodating a lock. The cover body is composed of an upper cover body, a middle cover body and a lower cover body connected to each other. The upper cover body is fixed with a lock body, which includes a lock core and a lock tongue fixedly connected to the lock core and extending downward; a coin outlet is provided at the bottom of the lower cover body, and a sliding door that can be moved back and forth to open or close the coin outlet is provided above the coin outlet. An upward hook lock bracket is fixedly connected to one side of the sliding door, and a tension spring is provided on the hook lock bracket to act on the sliding door to reset after it is opened. A hook lock plane extends from the upper part of the hook lock bracket and is parallel to the sliding door surface. A lock opening that can fall into the hook lock roller is provided at one end of the lock plane, and a mounting seat is fixedly provided at the bottom of the lower cover body. The mounting seat is rotatably connected to a linkage rod, and the upper end of the linkage rod extends to the upper cover body and is inserted into it by a lock tongue. A vertical dial column that can act on one end of a swing rod is fixed at the lower end of the linkage rod. The swing rod is rotatably connected to the mounting seat through a torsion spring and a rotating shaft, and a hook lock roller is rotatably provided at the other end of the swing rod. In addition, a convex-concave surface is extended to one side from the lock opening of the hook lock plane, and the notch of the convex-concave surface can allow the hook lock roller to fall into it after being unlocked.

[0005] Compared with the traditional coin recovery box, the present invention has the following advantages:

DETAILED DESCRIPTION

[0018] The present invention is further described below with reference to the accompanying drawings and embodiments.

[0019] Reference Figure 1The present invention includes a cover body capable of accommodating a lock, which is composed of an upper cover body 1, a middle cover body 2 and a lower cover body 3 connected to each other. The upper cover body 1 and the middle cover body 2 are rotatably connected by a hinge 4, and the middle cover body 2 and the lower cover body 3 are fixedly connected.

[0020] Reference Figure 2 The upper cover 1 is fixed with a lock body 5, which includes a lock core 5.1 and a lock tongue 5.2 fixedly connected to the lock core 5.1 and extending downward.

[0021] The lock body 5 of the upper cover 1 is also provided with a lock arm 5.3 which is fixedly connected to the lock cylinder 5.1 and the lock tongue 5.2 and can rotate synchronously. The side wall of the middle cover 2 is fixed with a lock buckle 5.4 which can be locked by the lock arm 5.3 (refer to Figure 1 ).

[0022] Reference Figures 3 to 5 A coin outlet 6 is provided at the bottom of the lower cover body 3, and a sliding door 7 is provided above the coin outlet 6, which can be moved back and forth to open or close the coin outlet 6. One side of the sliding door 7 is fixedly connected to an upward hook lock bracket 8, and a tension spring 9 is provided on the hook lock bracket 8 to act on the sliding door 7 to reset after opening. A hook lock plane 10 parallel to the surface of the sliding door 7 extends from the upper part of the hook lock bracket 8, and a lock port 11 that can fall into the hook lock roller 18 is provided at one end of the hook lock plane 10.

[0023] A mounting base 12 is also fixed at the bottom of the lower cover body 3, and the mounting base 12 is rotatably connected to a linkage rod 13. The upper end of the linkage rod 13 extends to the upper cover body 1 and is inserted into the locking tongue 5.2. A vertical dial column 15 that can act on one end of the rocker arm 14 is fixed at the lower end of the linkage rod 13.

[0024] The rocker arm 14 is rotatably connected to the mounting base 12 via a torsion spring 16 and a rotating shaft 17. A hook lock roller 18 is rotatably mounted on the other end of the rocker arm 14. In addition, a convex-concave surface 19 extends to one side from the lock opening 11 of the hook lock plane 10. The notch 19.1 of the convex-concave surface 19 enables the hook lock roller 18 to fall into it after being unlocked.

[0025] A cover shell 20 is fixedly disposed in the lower cover 3 to facilitate the entry of coins and to shield the sliding door 7 .

[0026] A socket 22 is provided on one side of the lower cover 3 for inserting a latch 21 to push the hook lock bracket 8 .

[0027] The present invention is only a door lock device for the upper cover of the recycling box, and when used, it should also be combined with the recycling box body (not shown in the figure). The present invention only needs one lock to complete the upper and lower locking linkage to realize the safety function of the coin recycling box.

[0028] Specifically, when the key is inserted into the lock body 5 and rotated to unlock it, the lock arm 5.3 is disengaged from the lock catch 5.4, and the upper cover body 1 is connected to the middle cover body 2 through the hinge 4. At this time, the upper cover body 1 can be flipped open.

[0029] The middle cover 2 and the lower cover 3 are fixed by screws. There are four inclined surfaces on the bottom to guide coins to the coin outlet 6. In addition, there is a triangular avoidance area in one corner of the box, which is used to make necessary space for the linkage rod 13.

[0030] The lower cover 3 is the key to the locking linkage mechanism. When the key is used to unlock the lock body 5 of the upper cover 1, the key is unlocked and rotated, and the lock tongue 5.2 also rotates and drives the inserted linkage rod 13 to rotate synchronously.

[0031] At this time, the vertical lever 15 on the linkage rod 13 in the lower cover body 3 acts on one end of the rocker 14, and the rocker 14 rotates counterclockwise, so that the hook lock roller 18 on the rocker 14 moves out of the lock hole 11 at one end of the hook lock plane 10 and falls into the notch 19.1 of the convex-concave surface 19 extending on one side to wait for further action (refer to Figure 6 ), at this time, the sliding door 7 has been unlocked, but is still in a closed state.

[0032] When the recycling box is placed in the device, the special latch 21 is inserted into the socket 22 of the lower cover 3 to push the hook lock bracket 8 to move. At this time, the hook lock roller 18 moves out of the recess 19.1, passes over the convex surface of the convex-concave surface 19 and falls on the flat surface on the side of the hook lock plane 10. The sliding door 7 is opened and the recycled coins can fall into the recycling box (refer to Figure 7 ).

[0033] When the recycling box reaches the storage capacity, the recycling box is taken out of the device, the latch 21 is withdrawn from the socket 22 of the lower cover 3, and the sliding door 7 is closed under the action of the tension spring 9. At this time, the hook lock roller 18 falls into the lock hole 11 at one end of the hook lock plane 10 (refer to Figure 8 ), the sliding door 7 is locked and cannot be opened again.

[0034] Therefore, the present invention can unlock the upper cover 1 and the coin slot sliding door 7 in the lower cover 3 at the same time, and the coin slot sliding door 7 cooperates with the linkage rod 13 and other components to form a single-use unlocking mechanism.

[0035] The present invention is not limited to this specific embodiment. For those skilled in the art, simple copying and modification without creative work fall within the scope of protection of the claims of the present invention.
