Description

Technical Field

[0001] This utility model relates to the field of banknote counting machine technology, specifically to a banknote counting machine with a banknote dispensing dust cover positioning structure. Background Technology

[0002] A banknote counter is an electromechanical device that automatically counts banknotes. It usually has a counterfeit banknote identification function and is a machine that combines counting and identifying counterfeit banknotes.

[0003] As shown in the Chinese utility model patent CN219658167U, which discloses a banknote counting machine with a dustproof device, conventional banknote counting machines have a dustproof cover at the banknote outlet. The dustproof cover is connected to the banknote outlet by shafts at both ends. When the banknote counting machine is not in use, the dustproof cover prevents dust from entering. During use, the dustproof cover is kept open by a damping connection between its two ends and the banknote outlet. However, the damping connection makes opening and closing the dustproof cover difficult. After long-term use, the connection between the dustproof cover and the banknote outlet wears down, and the damping fails. When taking out banknotes, one hand needs to hold the dustproof cover and the other hand needs to take out the banknotes, which is inconvenient. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a banknote counter with a banknote dust cover positioning structure.

[0005] The technical solution adopted by this utility model is as follows: A banknote counter with a banknote dispensing dust cover positioning structure includes a machine body, the machine body having a banknote dispensing port, a banknote dispensing dust cover being provided at the banknote dispensing port, the banknote dispensing dust cover being rotatably connected to the inner wall of the machine body on both sides via a shaft connection structure, and having a first dustproof position covering the banknote dispensing port and a first open position forming an open space with the banknote dispensing port.

[0006] The banknote dust cover has a first positioning protrusion / first positioning recess on both sides at positions different from the shaft connection structure.

[0007] Preferably, the inner wall of the machine body is also provided with a third positioning recess / third positioning protrusion corresponding to the first positioning protrusion / first positioning recess. When the banknote dust cover is rotated to the first dustproof position, at least part of the first positioning protrusion is located in the third positioning recess / at least part of the third positioning protrusion is located in the first positioning recess and restricts the rotation of the banknote dust cover.

[0008] Preferably, the banknote dust cover has a first positioning protrusion at a position on both sides opposite to the shaft connection structure, and the inner wall of the machine body has a corresponding second positioning recess and a third positioning recess.

[0009] Preferably, the first positioning protrusion has a convex arc surface on the end face corresponding to the inner wall of the machine body, and the second positioning recess and the third positioning recess are grooves provided on the inner wall of the machine body.

[0010] Preferably, the banknote dust cover has lugs on both sides that are perpendicular to its rotation axis, and the first positioning protrusion is connected to the lugs and is arranged parallel to the rotation axis of the banknote dust cover.

[0011] Preferably, the first positioning protrusion includes a hollow column connected to the lug and a positioning ball located at the end of the hollow column away from the lug, wherein the positioning ball is located outside the hollow column to form the first positioning protrusion.

[0012] Preferably, the shaft connection structure includes a rotating shaft connected to both sides of the cash dispensing dust cover / the inner wall of the machine body, and corresponding slots connected to the inner wall of the machine body / both sides of the cash dispensing dust cover to form a rotating connection with the rotating shaft, wherein the rotating shaft and the slot are in clearance fit.

[0013] The beneficial effects of this utility model are as follows: the cooperation between the first positioning protrusion / first positioning recess and the second positioning recess / second positioning protrusion not only forms a positioning mark for the banknote dust cover to turn to the first open position, but also enables it to remain in the first open position, thus facilitating the banknote retrieval operation.

Detailed Implementation

[0023] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0024] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0025] The directional and positional terms used in this utility model, such as "up," "down," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are merely for reference to the accompanying drawings. Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0026] like Figures 1 to 7 As shown in the illustration, a banknote counter with a banknote dispensing dust cover positioning structure is provided in an embodiment of this utility model. The banknote counter includes a body 1, which has a banknote dispensing port 11. A banknote dispensing dust cover 2 is provided at the banknote dispensing port 11. The banknote dispensing dust cover 2 is rotatably connected to the inner wall of the body 1 on both sides via a shaft connection structure, and rotates to have a first dustproof position covering the banknote dispensing port 11 and a first open position forming an open space with the banknote dispensing port 11.

[0027] The banknote dust cover 2 has a first positioning protrusion 21 / first positioning recess on both sides at positions different from the shaft connection structure. The inner wall of the machine body 1 has a corresponding second positioning recess 12 / second positioning protrusion. When the banknote dust cover 2 is rotated to the first open position, at least part of the first positioning protrusion 21 is located in the second positioning recess 12 / at least part of the second positioning protrusion is located in the first positioning recess and restricts the rotation of the banknote dust cover 2.

[0028] With this setting, the cooperation between the first positioning protrusion / first positioning recess and the second positioning recess / second positioning protrusion not only forms a positioning mark when the cash dispensing dust cover is turned to the first open position, but also keeps it in the first open position, making the cash dispensing operation more convenient.

[0029] The inner wall of the body 1 is also provided with a third positioning recess 13 / third positioning protrusion corresponding to the first positioning protrusion 21 / first positioning recess. When the banknote dust cover 2 is rotated to the first dust cover position, at least part of the first positioning protrusion 21 is located in the third positioning recess 13 / at least part of the third positioning protrusion is located in the first positioning recess and restricts the rotation of the banknote dust cover 2.

[0030] With this setting, the cooperation between the first positioning protrusion / first positioning recess and the third positioning recess / third positioning protrusion not only forms a positioning mark when the banknote dust cover is turned to the first dustproof position, but also makes it more stable in the first dustproof position, while avoiding accidental opening.

[0031] The banknote dust cover 2 has a first positioning protrusion 21 at the position of the shaft connection structure on both sides, and the inner wall of the machine body 1 has a second positioning recess 12 and a third positioning recess 13 respectively.

[0032] The first positioning protrusion 21 has a convex arc surface on the end face corresponding to the inner wall of the body 1, and the second positioning recess 12 and the third positioning recess 13 are grooves provided on the inner wall of the body 1.

[0033] This design ensures a stable fit between the groove and the spherical surface when the first positioning protrusion is connected to the second and third positioning recesses. It also makes the first positioning protrusion less prone to wear and reduces the need for excessive force when the banknote dust cover is rotated away from the first dustproof position and the first open position.

[0034] The banknote dust cover 2 has lugs 22 on both sides that are perpendicular to its rotation axis. The first positioning protrusion 21 is connected to the lugs 22 and is arranged parallel to the rotation axis of the banknote dust cover 2.

[0035] The first positioning protrusion 21 includes a hollow column 23 connected to the lug 22 and a positioning ball 24 located at the end of the hollow column 23 away from the lug 22. The positioning ball 24 is partially located outside the hollow column 23 to form the first positioning protrusion 21.

[0036] With this design, when a force is applied tangentially to the positioning ball, the hollow ball can rotate relative to it within the hollow column, thereby further reducing the wear on the first positioning protrusion during use. At the same time, the positioning ball and the hollow column are manufactured separately and then installed. The hollow ball can be made of a rigid material, while the hollow column is integrally formed with other structures, thereby strengthening the first positioning protrusion.

[0037] The shaft connection structure includes a rotating shaft 25 connected to both sides of the cash dispensing dust cover 2 / inner wall of the machine body 1, and a corresponding slot 14 connected to the inner wall of the machine body 1 / both sides of the cash dispensing dust cover 2 to form a rotating connection with the rotating shaft 25. The rotating shaft 25 and the slot 14 are in clearance fit.

[0038] Since stable positioning can be achieved by the cooperation of the positioning protrusion and the positioning recess, setting the rotating shaft and the slot to a clearance fit can make rotation more effortless.

[0039] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
