Detailed Implementation Manner

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0023] Please refer to Figures 1 to 3 , the present utility model provides a technical solution: a safety protection device for a POS machine, including a POS machine body 1, a screen 11 is arranged on the front side of the POS machine body 1 and a key area 12 is located below the screen 11. A protective cover 2 with a trough-shaped cross-section is also slidably connected up and down on the front side of the POS machine body 1. Among them, chutes are opened on the front side of the protective cover 2 near both sides and are slidably connected to the protective cover 2. When the protective cover 2 is slid up and down, the protective cover can switch between the screen 11 and the key area 12.

[0024] In this technical solution, an observation tube 4 is connected to the front of the protective cover 2, and a cover 5 is fixedly connected to the top of the observation tube 4. When in use, when entering a password, the eyes are attached to the cover 5. The cover 5 is a circular tube structure, and then the keys in the key area 12 inside the protective cover 2 can be observed through the observation tube 4. This setting enables the user to obtain all the images of the key area 12, and at the same time, the protective cover 2 can provide comprehensive protection for the key area 12. Then the operator inserts the hand into the key area 12 through the gap between the lower end of the protective cover 2 and the POS machine body 1 for key operation. Among them, a circle of silica gel pads 51 are bonded to the top opening of the cover 4, and the silica gel pads 51 play a role in protecting the eyes, that is, to avoid the silica gel pads 51 playing a buffering role when the eyes are attached to the cover 4.

[0025] Furthermore, a lighting lamp 6 is provided inside the protective cover 2. Since the inside of the protective cover 2 is in an approximately closed state, the light inside the protective cover 2 is relatively dim, making it difficult to clearly obtain the image of the key area 12. Therefore, the setting of the lighting lamp 6 can solve this problem.

[0026] In this embodiment, a baffle 13 located between the screen 11 and the key area 12 is fixedly connected to the front side of the POS machine body 1. When the protective cover 2 is located directly above the key area 12, the baffle 13 blocks the gap between the front end of the protective cover 2 and the front side of the POS machine body 1. This setting can effectively prevent the password from leaking through the gap between the front end of the protective cover 2 and the front side of the POS machine body 1.

[0027] Furthermore, a rubber pad 131 is bonded to the outer periphery of the baffle 13, and the rubber pad 131 is in pressing fit with the inner peripheral wall of the protective cover 2. This setting enables the protective cover 2 to stay stably when it contacts the baffle 13, avoiding the problem of random sliding of the protective cover 2 when entering the password.

[0028] In this embodiment, a photosensitive switch 7 and a storage battery 8 are provided on one side inside the protective cover 2. The photosensitive switch 7 is electrically connected to the lighting lamp 6 and the storage battery 8. Specifically, a battery installation groove can be opened on the inner wall of the protective cover 2, the battery is placed in the battery installation groove, and then a positioning groove for installing the lighting lamp 6 and the photosensitive switch 7 is opened on the inner wall of the protective cover 2. The lighting lamp 6 and the photosensitive switch 7 are both fixedly arranged in the positioning groove on the side wall inside the protective cover 2. When the light inside the protective cover 2 becomes dim, the photosensitive switch 7 controls the lighting lamp 6 to light up, improving the clarity of the image of the key area 12 obtained by the operator through the observation tube 4.

[0029] In this embodiment, a conical cover 21 protruding outward is fixedly connected to the front side of the protective cover 2. A jack 211 is opened at the top of the conical cover 21, and the jack 211 is located at the small end of the conical cover 21. The bottom of the observation tube 4 is fixedly connected with an insertion tube 42 that is inserted and matched with the jack 211. This setting has the function of facilitating the disassembly of the observation tube 4. After the observation tube 4 is removed, at this time, no matter where the protective cover 2 is located, the operator can comprehensively obtain the image inside the protective cover 2 through the jack 211, and then can perform non-password input operations on the POS machine.

[0030] Furthermore, a slot 14 that is inserted and matched with the insertion tube 42 is opened on one side outside the POS machine body 1. The slot 14 is used to temporarily place the observation tube 4, that is, when the observation tube 4 is not in use, it can be disassembled and then inserted into the slot 14 to avoid the problem of loss of the observation tube 4.

[0031] Working principle: When in use, when a password needs to be entered, manually pull down the protective cover 2. The protective cover is located directly above the key area 12 and will be clamped with the baffle 13. At this time, the front end of the protective cover 2 is in a closed state, and the rear end is the entrance for the hand to reach into the key area 12. Then insert the insertion tube 42 on the observation tube 4 into the jack 211. At this time, bring the eye close to and fit on the silica gel pad 51 on the cover 5, and then stretch the finger from the lower end of the protective cover 2 into the keyboard area 12, and enter the password according to the image obtained by the eye. Due to the shielding effect of the hand, the photosensitive switch 7 is triggered and the lighting lamp 6 is turned on, and the light in the protective cover 2 is enhanced, which is convenient for the operator to accurately enter the password. After the password is entered, pull out the observation tube 4, and then insert the insertion tube 42 into the slot 14 to perform non-password input operations on the key area 12.
