The storage box 4 is installed above the lifting mechanism 3, so that it can extend out of the receiving slot 11 or be stored in the receiving slot 11 under the drive of the lifting mechanism 3. The lifting mechanism 3 extends or contracts in the height direction, driving the storage box 4 to extend out of the receiving slot 11 to take out bills, or to be stored in the receiving slot 11 to store bills, thereby increasing the bill storage space and improving the convenience of taking bills.

[0058] In an exemplary embodiment, Figure 2 and Figure 3 As shown, the placement grooves 41 are arranged on the side walls of the storage box 4 and are evenly spaced in the height direction of the storage box 4. The size of the cross section of the placement grooves 41 is roughly the same as the size of the bill, or the width and depth of the slots of the placement grooves 41 are slightly larger than the size of the bill, so that a stack of bills can be placed in the placement grooves 41, reducing the degree of disorder of the bills in the placement grooves 41 and improving the neatness of storage.

[0059] In an exemplary embodiment, Figure 2 and Figure 3 As shown, the storage box 1 can also be a cuboid, a hexagonal prism, or a cylinder, which is not limited here. In this embodiment, the storage box 1 is a cuboid, and the receiving groove 11 is a rectangular groove. The receiving groove 11 runs through the top of the storage box 1 and forms an opening with the top of the storage box 1. The storage box 4 is used in conjunction with the receiving groove 11. When the storage box 4 is located in the receiving groove 11, the top of the storage box 4 is flush with the opening to close the opening. The bills in the placement groove 41 of the storage box 4 are stored in the storage box 4 and the storage box 1, which is convenient for carrying and moving the storage box 1, and improves the convenience of bill storage, storage and transportation.

[0060] In an exemplary embodiment, Figure 2 and Figure 3 As shown, the lifting mechanism 3 includes at least one group of lifting components 31. In this embodiment, two groups of lifting components 31 are provided. The two groups of lifting components 31 are respectively located at both ends of the storage box 4 in the lateral direction to maintain the balance of the storage box 4 so that the storage box 4 is subjected to balanced force during the process of rising or falling.

[0061] Figure 4 It is a three-dimensional schematic diagram of a lifting mechanism of a bill storage device according to an illustrative embodiment of the utility model.

[0062] In an alternative exemplary embodiment, a lifting mechanism is provided with a group of lifting components located in the middle of the storage box in the transverse direction, and the size of the lifting components in the transverse direction is smaller than the size of the storage box in the transverse direction to provide support force for the storage box and maintain balanced force on the storage box during the process of raising or lowering.

[0063] Specifically, Figure 3 and Figure 4 As shown, each lifting assembly 31 includes two connecting rods 312 and a rotating shaft 311. The rotating shaft 311 extends in the transverse direction, and the middle parts of the two connecting rods 312 are rotatably arranged to cross each other through the rotating shaft 311. The bottom ends of the two connecting rods 312 are configured to move toward or away from each other in the longitudinal direction under the drive of the driving mechanism 2, so that the lifting mechanism 3 is extended or contracted in the height direction.

[0064] According to the embodiment of the utility model, under the drive of the driving mechanism 2, when the bottom ends of the two connecting rods 312 move toward each other in the longitudinal direction, the two connecting rods 312 rotate around the rotating shaft 311, and the angle with the horizontal plane continues to increase, so that the lifting assembly 31 extends in the height direction, thereby raising the storage box 4 upward; when the bottom ends of the two connecting rods 312 move in the longitudinal direction toward the direction away from each other, the two connecting rods 312 rotate around the rotating shaft 311, and the angle with the horizontal plane continues to decrease, so that the lifting assembly 31 shrinks in the height direction, thereby driving the storage box 4 to be stored in the storage box 1, so that the storage box 4 is convenient for rising to take the bills or descending to the receiving slot 11 to store the bills, thereby improving the convenience of taking and putting the bills.

[0065] In an exemplary embodiment, Figure 3 and Figure 4 As shown, the middle parts of the two connecting rods 312 are recessed on one side facing each other to form a clearance groove 3121, which allows the two connecting rods 312 to rotate around the rotation axis 311 and reduces the width of the two connecting rods 312 in the lateral direction, thereby reducing space occupation.

[0066] In an exemplary embodiment, Figure 2 and Figure 3 As shown, the bottom of the front side wall of the storage box 1 is provided with a through hole 12 connected to the receiving groove 11, and the through hole 12 extends in the transverse direction of the storage box 1. The driving mechanism 2 is located in the through hole 12 and is slidably mounted on the storage box 1 in the longitudinal direction. The driving mechanism 2 is configured to drive the bottoms of the two connecting rods 312 to approach each other during the process of sliding into the receiving groove 11, and drive the two connecting rods 312 to move away from each other during the process of moving toward the through hole 12.

[0067] In an exemplary embodiment, Figure 2and Figure 3 As shown, the driving mechanism 2 includes a driving plate 21 and a connecting assembly 22. The driving plate 21 is located in the through hole 12 and is slidably installed in the storage box 1 in the longitudinal direction. The connecting assembly 22 is installed on the side of the driving plate 21 away from the through hole 12.

[0068] The bottom of one of the connecting rods 312 adjacent to the through hole 12 in a set of lifting components 31 is hinged to the connecting component 22, and the bottom of the other connecting rod 312 away from the through hole 12 is hinged to the inner wall of the storage box 1, so that under the drive of the driving plate 21, the bottom ends of the two connecting rods 312 are moved closer to or away from each other.

[0069] According to the embodiment of the utility model, when the driving mechanism 2 drives the two connecting rods 312 to rotate, the driving plate 21 is pushed into the through hole 12 in the longitudinal direction, and the driving plate 21 drives the bottoms of the two connecting rods 312 to move toward each other and stretch, so as to raise the storage box 4 and extend it out of the receiving groove 11. When the driving plate 21 is pulled outward in the longitudinal direction, the driving plate 21 drives the bottoms of the two connecting rods 312 to move away from each other and shrink, so that the storage box 4 is lowered and stored in the receiving groove 11, which is convenient to operate and improves the convenience of taking and storing bills.

[0070] In an exemplary embodiment, Figure 1 and Figure 3 As shown, the driving plate 21 includes two straight plate portions 211 and a bent portion 212. The two straight plate portions 211 are spaced apart in the transverse direction to form a first slot 213, and a connecting assembly 22 is respectively provided on one side of the two straight plate portions 211 away from the through hole 12, and the two connecting assemblies 22 are respectively hinged to the bottom of the connecting rod 312 of the two lifting assemblies 31 adjacent to the through hole 12.

[0071] The bent portion 212 is installed at one end of the two straight plate portions 211 adjacent to each other, and is bent into the receiving groove 11 to form a second groove 214. The width of the second groove 214 is greater than the width of the first groove 213. The second groove 214 can accommodate the operator's finger to allow the driving plate 21 to be pulled in a direction away from the receiving groove 11. The bent portion 212 is integrally formed with the straight plate portion 211, which increases the rigidity of the driving plate 21.

[0072] According to the embodiment of the utility model, in the process of pulling the driving plate 21 in the direction away from the accommodating groove 11 in the longitudinal direction, since the width of the second groove 214 is greater than the width of the first groove 213, the operator's fingers can be inserted into the second groove 214 and apply a pulling force outward, thereby driving the bottom ends of the two connecting rods 312 to move in the direction away from each other, avoiding the inconvenience of pulling out due to the friction resistance between the driving plate 21 and the storage box 1, facilitating the reciprocating movement of the driving plate 21 in the longitudinal direction, and improving the convenience of extending the storage box 4 from the accommodating groove 11 or being accommodated in the accommodating groove 11.

[0073] In a replaceable exemplary embodiment, an open slot is provided on the driving plate, and the open slot runs through the driving plate. The open slot can accommodate the fingers of an operator, so that the fingers of the operator can be inserted into the open slot and pull the driving plate outward, thereby avoiding the inconvenience of pulling out due to the friction resistance between the driving plate and the storage box, and facilitating the reciprocating movement of the driving plate in the longitudinal direction.

[0074] In an exemplary embodiment, Figure 1 As shown, guide blocks 5 are respectively provided at both ends of the driving plate 21 in the transverse direction, and the inner wall of the storage box 1 is provided with a guide groove 13 cooperating with the guide block 5. The guide groove 13 extends in the longitudinal direction to guide the driving plate 21 to slide in the longitudinal direction, thereby reducing the degree of shaking of the driving plate 21 during movement.

[0075] Figure 5 It is a three-dimensional schematic diagram of a storage box of a bill storage device according to an illustrative embodiment of the utility model.

[0076] In an exemplary embodiment, Figure 3 and Figure 5 As shown, the top ends of the two connecting rods 312 are both hinged with sliders 313 , and the bottom of the storage box 4 is provided with a slide groove 42 extending in the longitudinal direction and cooperating with the sliders 313 .

[0077] Specifically, the slider 313 includes a slide plate and a support arm. The slide plate is horizontally arranged. The support arm is installed at the bottom of the slide plate. The width of the support arm is smaller than the width of the slide plate. The slide plate and the support arm form a T-shaped slider 313.

[0078] In an exemplary embodiment, Figure 3 and Figure 5 As shown, the slide groove 42 used in conjunction with the slider 313 is T-shaped, and the slide groove 42 includes a first groove 421 and a second groove 422 from bottom to top. The width of the second groove 422 is greater than the first groove 421, the slide plate is slidably disposed in the second slide groove 42, the support arm is slidably disposed in the first groove 421, and the second groove 422 is configured to allow the slider 313 to pull the storage box 4 downward to overcome the friction resistance between the storage box 4 and the storage box 1.

[0079] According to an embodiment of the utility model, during the process of the two connecting rods 312 rotating and contracting, the slider 313 slides in the slide groove 42. Since the width of the second groove 422 is greater than the width of the first groove 421, the connecting rod 312 drives the slider to pull the storage box 4 downward to overcome the friction resistance between the storage box 4 and the storage box 1, thereby preventing the storage box 4 from getting stuck in the storage box 1.

[0080] In an exemplary embodiment, a roller (not shown in the figure) is rotatably connected to the top of the skateboard, and the roller is located in the second groove 422 , and the roller is in rolling contact with the storage box 4 .

[0081] According to an embodiment of the utility model, when the lifting assembly 31 is extended or retracted, the rollers roll in contact with the storage box 4 during the sliding of the slide plate in the second groove 422, so as to reduce the friction resistance between the slide plate and the storage box 4 and improve the smoothness of the lifting mechanism 3 driving the storage box 4 to rise or fall.

[0082] In a replaceable exemplary embodiment, a plurality of balls are embedded in the top surface of each slide plate, the plurality of balls are distributed at intervals, and the plurality of balls are in rolling contact with the storage box to reduce the friction resistance between the slide plate and the storage box 4, thereby facilitating the slide plate to slide in the second groove.
