[0022] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a POS machine for preventing accidental button presses of the present utility model with reference to the accompanying drawings.

[0023] As Figures 1-3As shown in the figure, an embodiment of the present utility model for a POS machine that prevents accidental touch of buttons includes a POS machine body 1 and a mounting block 2 fixedly arranged on the POS machine body 1. A pair of mounting blocks 2 are fixedly arranged on the left and right sides of the POS machine body 1 by bolts. Among them, a rotating shaft 3 with an axially horizontal arrangement is rotatably provided on the mounting block 2. An active frame 5 is provided at the button of the POS machine body 1, and the active frame 5 is fixedly arranged with the rotating shaft 3 through a connecting block 4. The active frame 5 is provided with a transparent plate 6 for protecting the buttons of the POS machine body 1. The transparent plate 6 covers the button of the POS machine body 1 to protect the button. When it is necessary to use the button of the POS machine body 1, apply force to the active frame 5 to rotate it to the display screen of the POS machine body 1 through the rotating shaft 3. In addition, an anti-peeping film 7 is provided on the side of the transparent plate 6 close to the button of the POS machine body 1. When it is necessary to use the POS machine body 1, apply force to the active frame 5 to rotate the active frame 5, the transparent plate 6 and the anti-peeping film 7 to the display screen of the POS machine body 1 to cover the display screen. The anti-peeping film 7 will be on the side of the transparent plate 6 away from the POS machine body 1. After the rotation is completed, the POS machine body 1 can be used. And under the action of the transparent plate 6 and the anti-peeping film 7, it is possible to prevent others from peeping at the screen. Additionally, anti-slip members 8 are provided on both sides of the active frame 5 to facilitate better picking up of the active frame 5 when applying force to the active frame 5. In addition, a locking mechanism 9 for locking the active frame 5 is provided on the POS machine body 1. When the active frame 5 is at the button of the POS machine body 1, it is locked by the locking mechanism 9 to prevent the active frame 5 from opening after accidental touch. A positioning mechanism 10 for clamping the rotating shaft 3 is also provided on the POS machine body 1. When the active frame 5 rotates to the display screen of the POS machine body 1, the positioning mechanism 10 clamps the rotating shaft 3 to prevent the active frame 5 from rotating when using the POS machine body 1.

[0024] As Figure 4As shown in the figure, the locking mechanism 9 includes a sliding block 903 and a guiding groove 901 provided on the side of the POS machine body 1. A guiding rod 902 arranged horizontally in the axial direction is provided in the guiding groove 901. One end of the sliding block 903 is slidably arranged on the guiding rod 902, and a stop block 904 is fixedly provided at the other end. Under the action of the guiding rod 902, the sliding block 903 and the stop block 904 slide on the POS machine body 1. In addition, in order to enable the sliding block 903 to automatically reset, a first spring 906 for applying force to the sliding block 903 is wound around the guiding rod 902. When force is applied to the sliding block 903 to slide on the guiding rod 902, the first spring 906 is compressed. When the force applied to the sliding block 903 stops, under the action of the compressed first spring 906, the sliding block 903 automatically resets, driving the stop block 904 to reset together. On one side of the movable frame 5 close to the sliding block 903, a clamping block 905 for being locked by the stop block 904 is provided. The stop block 904 and the clamping block 905 are in interference fit, so that the stop block 904 locks the clamping block 905. When unlocking is required, force is applied to the sliding block 903, and the sliding block 903 slides on the guiding rod 902. The sliding block 903 drives the stop block 904 to disengage from the clamping block 905, completing the unlocking of the movable frame 5.

[0025] As Figures 5-6 shown in the figure, the positioning mechanism 10 includes a support frame 1001 fixedly arranged on the POS machine body 1 and a rotating block 1002 fixedly arranged on the rotating shaft 3. The rotating block 1002 is placed inside the support frame 1001, and a clamping groove 1003 is provided on the side of the rotating block 1002 away from the display screen of the POS machine body 1. When the movable frame 5 rotates, the rotating shaft 3 drives the rotating block 1002 to rotate together. Among them, a sliding groove rod 1004 is fixedly arranged on the inner side wall of the support frame 1001. A sliding chamber is provided inside the sliding groove rod 1004. One end of a clamping rod 1005 for clamping the clamping groove 1003 is slidably arranged in the sliding chamber, and the other end is in contact with the surface of the rotating block 1002. And a second spring 1006 for applying force to the clamping rod 1005 is provided in the sliding chamber of the sliding groove rod 1004. Specifically, when the clamping rod 1005 is in contact with the surface of the rotating block 1002, the second spring 1006 is in a compressed state. When the movable frame 5 rotates, the rotating shaft 3 drives the rotating block 1002 to rotate together, and the clamping groove 1003 also rotates together. When the movable frame 5 rotates to the display screen of the POS machine body 1 and covers it, the clamping rod 1005 is clamped into the clamping groove 1003 under the action of the spring force, clamping the rotating block 1002 tightly, thereby also achieving the effect of clamping the rotating shaft 3 tightly. When resetting is required, after applying force to the movable frame 5, the clamping rod 1005 can automatically disengage from the clamping groove 1003.

[0026] In summary, the specific working principle is as follows: When the POS machine main body 1 needs to be used, a force is applied to the sliding block 903, and the sliding block 903 slides to the right. The sliding block 903 drives the stopper 904 to disengage from the clamping block 905, completing the unlocking of the movable frame 5. After unlocking, the movable frame 5 can be rotated and rotated to the display screen of the POS machine main body 1. The anti-peeping film 7 will be on the side of the transparent plate 6 away from the POS machine main body 1. Under the action of the transparent plate 6 and the anti-peeping film 7, others are prevented from peeping at the screen. After the rotation is completed, the clamping rod 1005 is clamped into the clamping groove 1003 under the action of the spring force, and the rotating block 1002 is clamped tightly, thereby also achieving the effect of clamping the rotating shaft 3. When the POS machine main body 1 does not need to be used, a force is applied to the movable frame 5, and the clamping rod 1005 can automatically disengage from the clamping groove 1003. The movable frame 5 and the transparent plate 6 cover the button part of the POS machine main body 1 again. After applying a force to the sliding block 903, the stopper 904 locks the clamping block 905 to prevent the movable frame 5 from opening after accidental contact.
