DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 4 As shown, a lock for a safety box includes: an upper fixing seat 1, a lower fixing seat 2, a pressing buckle plate 3, a locking plate 4 and a lock buckle 5.

[0025] The upper fixing seat 1 is correspondingly arranged above the lower fixing seat 2. When in use, the upper fixing seat 1 and the lower fixing seat 2 are respectively fixed to the hinged upper and lower halves of the safety box, and the positions are corresponding. When the safety box is closed, the bottom surface of the upper fixing seat 1 is close to the top surface of the lower fixing seat 2.

[0026] like Figure 4 As shown, the top of the pressing buckle plate 3 is hinged to the upper fixing seat 1, and the bottom extends to the lower fixing seat 2, so that the upper and lower fixing seats can be connected together. Figure 1 and Figure 2 As shown, the middle parts of the upper fixing seat 1 and the lower fixing seat 2 are concave to form a mounting groove, and the pressing buckle plate 3 is arranged in the mounting groove.

[0027] A through hole is provided in the middle of the pressing buckle plate 3. The lock buckle 5 is fixedly arranged in the through hole. A keyhole is provided at one end of the lock buckle 5, and a locking key 6 is provided at the other end. The locking key 6 can cooperate with the lower fixing seat 2 to fix the pressing buckle plate 3. The locking key 6 is controlled to move by the key inserted into the keyhole, and can be locked or unlocked with the lower fixing seat 2. Specifically, a lock hole 8 is provided at the position of the lower fixing seat 2 corresponding to the lock buckle 5, and a locking protrusion 9 is provided in the lock hole 8. The locking key 6 is placed in the lock hole 8, and it can be rotated to cooperate with the locking protrusion 9 under the drive of the key. The lock hole 8 is circular, and the locking protrusion 9 extends a short distance inward from the edge of the circular lock hole 8. When the end of the locking key 6 rotates to the locking protrusion 9, locking is achieved, and when the end of the locking key 6 rotates out of the locking protrusion 9, unlocking is achieved.

[0028] like Figure 4 and Figure 7 As shown, the locking plate 4 is arranged between the pressing buckle plate 3 and the lower fixing seat 2, and is elastically hinged on the pressing buckle plate 3. The elastic hinge means that the locking plate 4 maintains a relative position with the pressing buckle plate 3 under the action of the elastic member, and the locking plate 4 can rotate relatively under the action of an external force. After the external force is lost, the locking plate 4 returns to its original position under the action of the elastic member.

[0029] like Figure 6 and Figure 7 As shown, a locking hook 15 is provided at the bottom of the locking plate 4, and the locking hook 15 cooperates with the locking hole 7 opened on the lower fixing seat 2 to realize the relative fixation of the pressing plate 3 and the lower fixing seat 2. The cooperation between the locking hook 15 and the locking hole 7 can be released by rotating the locking plate 4.

[0030] The first end of the locking plate 4 is hinged to the pressing plate 3, and the second end extends to the outside of the pressing plate 3 so that the operator can press it. The locking plate 4 is provided with a groove, and a spring sheet 10 is arranged in the groove. One end of the spring sheet 10 abuts against the pressing plate 3, so that the locking plate 4 is elastically hinged to the pressing plate 3. The bottom surface of the lock hook 15 is an arc structure, so that the lock hook 15 is automatically embedded in the locking hole 7 when pressed.

[0031] like Figure 4 As shown, the end surface of the lower fixing seat 2 facing the upper fixing seat 1 is provided with a positioning protrusion 11. There are two positioning protrusions 11, which are arranged near both sides of the lower fixing seat 2. The end surface of the upper fixing seat 1 facing the lower fixing seat 2 is provided with a positioning groove 12. There are two positioning grooves 12, which are arranged near both sides of the upper fixing seat 1. The positioning protrusion 11 is adapted to the positioning groove 12 for positioning.

[0032] The two side surfaces of the upper fixing seat 1 are concave to form recessed portions 13 so that the upper fixing seat 1 can be grasped by fingers.

[0033] like Figure 2 and Figure 5 As shown, a sealing plate 14 is provided on the back of the upper fixing seat 1. A gap is provided at the hinge between the upper fixing seat 1 and the pressing buckle plate 3. In order to cover the gap and improve the integrity and aesthetics of the lock, a sealing plate 14 is provided on the upper fixing seat 1. An opening is provided on the sealing plate 14. An anchor-type fixing pin is provided on the back of the upper fixing seat 1, and the anchor-type fixing pin is inserted into the opening to achieve a fixed connection between the sealing plate 14 and the upper fixing seat 1.

[0034] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
