Description

Technical Field

[0001] This utility model relates to the technical field of self-service machines, and more specifically to a lid-opening mechanism and a self-service device having the lid-opening mechanism. Background Technology

[0002] To save labor costs and improve service quality, the use of self-service equipment is becoming increasingly widespread, such as self-service ticket machines or self-service checkout machines in supermarkets. These self-service machines are also equipped with display screens, printers, and scanners, depending on user needs. These mechanisms are generally installed inside the machine itself. Taking printers as an example, the paper trays in small self-service machines are generally small, resulting in rapid paper consumption. This necessitates frequent paper replacement by maintenance personnel. Replacement requires repeatedly opening the printer tray door or cover, and typically, the door or cover needs to be opened to allow access to the corresponding area (such as the paper roll housing) to disassemble and reinstall the paper roll. Based on design requirements (such as a better appearance compared to side-opening doors or saving side space), the compartment door or cover needs to be designed to open upwards. Common upward-opening or upward-flipping compartment door structures require support rods to maintain the open position after the cover (or door) is opened. These support rods need to be positioned after the cover is opened and retracted when the cover is closed, requiring a positioning mechanism, etc. This structure is complex, increases costs, and is not convenient to operate. This case arises from this need. Utility Model Content

[0003] The purpose of this utility model is to provide a lid-opening mechanism and a self-service device having the lid-opening mechanism, which has a simple structure and is easy to operate.

[0004] To achieve the above objectives, the solution of this utility model is:

[0005] A cover-opening mechanism is provided for opening and closing a flip cover inside a housing. The front side of the housing is connected to a flip cover that can be lifted upwards to close. The flip cover is mounted on the housing and can be opened and closed via the cover-opening mechanism.

[0006] The flip cover includes side cover plates extending rearward from both sides of the front cover plate, and the outer shell includes side cover plates extending forward from both sides of the rear plate. The opening mechanism includes a support rod and a tension spring, with the front end of the support rod pivotally connected to the side cover plate.

[0007] A strip-shaped groove runs through the support rod along its length. The groove is located behind the pivot point at the front end of the support rod. A positioning shaft is provided on the inner side of the side plate. The positioning shaft passes through and is limited in the groove so that the groove slides back and forth relative to the positioning shaft. The support rod slides outward and tilts upward with the flip cover to stand up.

[0008] The lower end of the tension spring is connected to the rear end of the support rod, and the upper end of the tension spring is connected to the rear plate of the housing. At the end of the slide groove, a positioning slot is formed in the direction of the tension spring. The support rod slides outward at an angle until the positioning shaft reaches the end of the slide groove. Then, the tension spring with tension force drives the positioning shaft to fall into the positioning slot for positioning.

[0009] Furthermore, the support rod is located on the inner side of the side cover and the side plate, the pivot point at the front end of the support rod is located above the positioning shaft, the support rod is inclined between the flip cover and the outer shell, and the tension spring is inclined in the opposite direction to the support rod.

[0010] Furthermore, the slide is L-shaped, and a limiting pin is provided on the side of the positioning slot in the support rod, with the lower end of the tension spring hooked on the limiting pin.

[0011] Furthermore, an opening mechanism is provided on one or both sides of the outer shell; when two opening mechanisms are provided, they form a symmetrical arrangement.

[0012] Furthermore, in the outer casing, a locking block is installed at the lower end of the inner side of one of the side panels. The locking block is connected to a push-button pin tumbler lock, which is installed on the outer side of the side panel. At least one positioning block is protruding from the locking block toward the outer side of the side panel. At least one positioning hole is provided on the corresponding side cover of the flip cover, which can be located outside the positioning block when the flip cover is closed. When the push-button pin tumbler lock is operated, the positioning block in the locking block pops out or is pushed outward to the positioning hole to lock the flip cover.

[0013] Furthermore, the outer casing also includes a top plate and a bottom plate, with a mounting base connected inside the casing. A connecting block extends forward from the upper end of the side plate and is located in front of the top plate. The upper ends of the two side covers of the flip cover are pivotally connected to the connecting block.

[0014] Furthermore, the top and bottom of the flip cover are respectively provided with a top cover plate and a bottom cover plate located inside the top and bottom of the two side cover plates. The connecting block is recessed downward to form an avoidance notch, and the top cover plate of the flip cover enters the avoidance notch when the flip cover is flipped up.

[0015] A self-service device includes a support assembly and a display assembly. The support assembly has a housing and a flip cover, and an opening mechanism is connected between the housing and the flip cover.

[0016] Furthermore, the housing is located at the bottom of the bracket assembly, and the printer is installed inside the housing.

[0017] With the above structure, the opening mechanism of this utility model can be applied to housings that require an upward-flipping lid. Using this mechanism, after the lid is opened, it can be positioned in the open state and maintained, facilitating post-opening operations by staff. Conversely, it can easily release the positioning, allowing the lid to close normally. The opening mechanism of this utility model has a simple structure, is easy and quick to operate, and greatly saves costs. This opening mechanism can also be used in self-service equipment to facilitate the operation of frequently opened and closed compartment doors. Attached Figure Description

[0032] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0033] Combination Figures 2 to 6 As shown, this utility model discloses a cover opening mechanism for opening and closing a flip cover 2 in a housing 1. The front side of the housing 1 is connected to a flip cover 2 that can be lifted upwards and closed. The flip cover 2 is installed on the housing 1 through the cover opening mechanism.

[0034] The flip cover 2 includes side cover plates 22 extending rearward from both sides of the front cover plate 21, and the outer shell 1 includes side plates 12 extending forward from both sides of the rear plate 11. The opening mechanism includes a support rod 3 and a tension spring 4. The front end of the support rod 3 is pivotally connected to the side cover plate 22 of the flip cover 2. A strip-shaped groove 31 is provided through the support rod 3 along its length. The groove 31 is located behind the pivot point at the front end of the support rod 3. A positioning shaft 15 is provided on the inner side of the side plate 12. The positioning shaft 15 can pass through and be limited in the groove 31 so that the groove can slide back and forth relative to the positioning shaft 15. The support rod 3, which slides outward, can tilt upward and flip up with the flip cover 2.

[0035] The lower end of the tension spring 4 is connected to the rear end of the support rod 3, and the upper end of the tension spring 4 is connected to the rear plate 11 of the outer shell 1. The end of the slide groove 31 of the support rod 3 extends toward the tension spring 4 to form a positioning groove 32. After the support rod 3 slides outward to the positioning shaft 15 reaching the end of the slide groove 31, the tension spring 4 with tension force can drive the positioning shaft 15 to fall into the positioning groove 32 for positioning, so that the flip cover 2 supported by the support rod 3 can be positioned in the open state.

[0036] like Figure 3 , Figure 4 As shown, the support rod 3 is positioned on the inner side of the side cover plate 22 and the side plate 12. The pivot point between the front end of the support rod 3 and the side cover plate 22 is located above the positioning shaft 15, so that the support rod 3 is tilted between the flip cover 2 and the outer shell 1. The tension spring 4 is tilted in the opposite direction to the support rod 3. The tension spring 4 and the support rod tilting from bottom to top towards the flip cover form an intersection near the bottom. The tension spring 4 will be appropriately stretched outward when the support rod 3 is pushed outward. When the support rod 3 tilts outward and pushes the flip cover 2 to meet a certain opening angle, the positioning shaft 15 just reaches the end of the slide groove 31. The tension spring 4, after being pulled, can drive the positioning shaft 15 to fall into the positioning groove 32 for positioning when the positioning shaft 15 reaches the positioning slot 32 at the end of the slide groove 31 (at this time, the tension spring is still in the continuous tension state). When releasing the positioning, simply press down on the support rod 3 with your hand to return the positioning shaft 15 in the positioning slot 32 to the slide groove 31. Then the positioning shaft 15 can slide along the slide groove 31, and the support rod 3 will drive the flip cover 2 to retract downwards to the closed state (at this time, it can be adjusted according to the position, and the tension spring is designed to be in a free state).

[0037] As shown in Figure 6, in this embodiment, the slide groove 31 of the support rod 3 is L-shaped, and a limiting pin 33 is provided on the side of the positioning groove 32 in the support rod 3. The lower end of the tension spring 4 can be directly hooked on the limiting pin 33.

[0038] Regarding the setting of the opening mechanism, it is sufficient to set the opening mechanism only on one side panel of the outer shell 1. Of course, it is also possible to set the opening mechanism on both sides. When there are two opening mechanisms, they form a symmetrical relationship.

[0039] Furthermore, to enable the flip cover 2 to be locked in the closed state, in this example, a locking block 51 is installed at the lower end of the inner side of one of the side panels 12 in the outer casing. The locking block 51 is connected to a push-button pin tumbler lock 52, which is installed on the outer side of the side panel 12. The locking block 51 has at least one positioning block 511 protruding outward from the side panel 12. In this embodiment, there are two positioning blocks. The corresponding side cover plate 22 of the flip cover 2 has at least one positioning hole 221, which can be located outside the positioning block 511 when the flip cover 2 is closed. When the push-button pin tumbler lock is operated, the positioning block 511 in the locking block 51 can be popped out or pushed outward to be positioned on the positioning hole 221 to lock the flip cover 2. The side cover plate 22 also has a clearance slot 222 that can avoid the push-button pin tumbler lock 52, located outside the positioning hole 221.

[0040] Additionally, the outer casing 1 may include a top plate 13 and a bottom plate 14. A mounting base 6 may be connected inside the outer casing 1, which can be used to connect or install components such as a printer. A connecting block 121 extends forward from the upper end of the side plate 12 and is located in front of the top plate. The upper ends of the two side cover plates 22 of the flip cover 2 are pivotally connected to the connecting block 121. The top and bottom of the flip cover 2 may also be provided with a top cover plate 23 and a bottom cover plate 24 located inside the top and bottom of the side cover plates 22, respectively. A clearance notch 122 is recessed downward in the connecting block 121 of the side plate 12. When the flip cover 2 is flipped upward, the top cover plate 23 can enter the clearance notch 122 to avoid interference.

[0041] In use, the flip cover 2 is pivotally connected to the outer shell. When the flip cover 2 is opened, the support rod 3 simultaneously tilts and pushes outward. As the support rod 3 continues to push outward, when the positioning shaft 15 reaches the positioning slot 32 at the end of the slide groove 31, the tension spring pulls the positioning shaft 15 into the positioning slot 32 for positioning. The flip cover 2 is then positioned in the open state, facilitating the opening operation. Conversely, when it is necessary to release the positioning of the support rod 3, simply press down on the support rod 3 with your hand to return the positioning shaft 15 from the positioning slot 32 back into the slide groove 31. Then, the positioning shaft 15 can slide along the slide groove 31, and the support rod 3 pulls the flip cover 2 downward until it closes on the front side of the outer shell 1.

[0042] like Figure 1As shown, this utility model also discloses a self-service device, which includes a support assembly A and a display assembly B. The support assembly A has the aforementioned outer shell 1 and flip cover 2, and an opening mechanism connects the outer shell 1 and the flip cover 2. The outer shell 1 can be located at the bottom of the support assembly A, and a printer is installed inside the outer shell 1. The flip cover 2 can be easily opened using the opening mechanism, facilitating paper replacement or inspection. Of course, the opening mechanism of this utility model can also be applied to many other housings that require an upward-opening flip cover.

[0043] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
