Description

Technical Field

[0001] This utility model relates to the field of POS machine equipment technology, specifically a retractable wall-mounted POS machine. Background Technology

[0002] POS machines, as common commercial payment terminals, are widely used in retail, catering, and other venues. Currently, there are two main types of POS machines on the market: desktop POS machines and wall-mounted POS machines. Existing wall-mounted POS machines are exposed to the elements for extended periods and cannot be stored away when not in use. This not only occupies wall space but is also susceptible to dust accumulation and accidental impacts, leading to equipment damage or wear and tear, shortening their lifespan. Furthermore, the angle of the display screen and control panel of wall-mounted POS machines is often fixed, making it impossible to flexibly adjust according to the operator's height, usage habits, or transaction scenario (such as standing or sitting operation), which can easily lead to visual fatigue and reduce transaction efficiency.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 6 This utility model provides a technical solution: a retractable wall-mounted POS machine, including a wall-mounted base 1, a storage frame 2 fixedly connected to the front side of the wall-mounted base 1, a POS machine body 3 placed inside the storage frame 2, a closing cover 4 provided on one side plate at the opening of the storage frame 2, an installation block 5 provided inside the storage frame 2 on the back side of the POS machine body 3, an adjustment component 6 provided between the installation block 5 and the bottom wall of the wall-mounted base 1, an L-shaped movable clamp 7 overlapping the POS machine body 3 on the upper side of the installation block 5, and a fixed support plate 8 fixedly connected below the installation block 5 and overlapping the bottom of the POS machine body 3.

[0024] In this embodiment, connecting posts 9 are fixedly connected to both sides of the fixed support plate 8, and grooves 10 are provided on both sides of the POS machine body 3. The connecting posts 9 rotate and slide in the inner wall of the grooves 10. A connecting groove 11 is provided downward on the upper side of the mounting block 5. The longitudinal plate of the L-shaped movable clamping block 7 slides in the inner wall of the connecting groove 11. A tension spring 12 is fixedly connected between the bottom of the longitudinal plate of the L-shaped movable clamping block 7 and the bottom wall of the connecting groove 11. A storage groove 13 is provided inward on the outer side of one side plate of the opening of the storage frame 2. The closing cover 4 slides in the inner wall of the storage groove 13. A limit strip 14 slides in the inner wall of the storage groove 13. Two fixing blocks 15 are fixedly connected to one side of the limit strip 14. Rotating shafts 16 that rotate in cooperation with the two fixing blocks 15 are fixedly connected to the upper and lower sides of one side of the closing cover 4. A torsion spring is provided at the rotation point between the rotating shaft 16 and the fixing blocks 15.

[0025] Specifically, when the POS machine is needed, the closing cover 4 is pulled outward from the storage slot 13. The closing cover 4 rotates around the fixed block 15 via the rotating shaft 16, and at the same time drives the limiting strip 14 to slide along the storage slot 13. Since there is a torsion spring at the rotation point of the rotating shaft 16 and the fixed block 15, the torsion spring stores elastic potential energy during the rotation of the closing cover 4. When the closing cover 4 rotates to a position perpendicular to the opening of the storage frame 2, the limiting strip 14 slides to the limit position in the storage slot 13, thus limiting the closing cover 4. At this time, the closing cover 4 remains open and does not obstruct the display screen and operation panel of the POS machine body 3. The operator can perform transaction operations such as swiping cards and entering passwords normally.

[0026] In this embodiment, the adjustment component 6 includes a connecting block 601 disposed on the rear side of the mounting block 5. Slide grooves 602 are provided on both the upper and lower sides of the bottom wall of the storage frame 2. Sliding sliders 603 are slidably fitted onto the inner walls of both slide grooves 602. Connecting brackets 604 are respectively provided between the two sliders 603 and the upper and lower sides of the connecting block 601. One end of the connecting bracket 604 is rotatably fitted with the slider 603, and the other end is rotatably fitted with one side of the connecting block 601. A bidirectional screw 605 is rotatably fitted onto the outer side of the bottom edge of the storage frame 2, penetrating into the two slide grooves 602. The two threads of the screw 605 are respectively located in the two sliding grooves 602 and are threadedly engaged with the slider 603 inside them. The back side of the mounting block 5 is provided with a ball socket groove 606. The front side of the connecting block 601 is fixedly connected with a connecting ball 607 that is movably engaged in the ball socket groove 606. The inner wall of the ball socket groove 606 is provided with a downward stroke groove 608. The inner wall of the stroke groove 608 is slidably engaged with an abutment block 610 that overlaps with the surface of the connecting ball 607. The lower side of the abutment block 610 is fixedly connected with a positioning screw 609 that is threadedly engaged with the mounting block 5 and extends through to the outside of it.

[0027] Specifically, when it is necessary to adjust the forward and backward tilt angle of the POS machine body 3 according to the operator's height or operating posture, rotate the bidirectional screw 605 on the outside of the bottom edge of the storage frame 2. Since the two threaded sections of the bidirectional screw 605 are respectively threadedly engaged with the sliders 603 in the two slide grooves 602, when the bidirectional screw 605 rotates, it will drive the two sliders 603 to slide in opposite directions along the slide grooves 602; the sliders 603 drive the connecting block 601 to move back and forth through the connecting bracket 604, and the connecting ball 607 on the front side of the connecting block 601 moves synchronously in the ball socket 606 on the back side of the mounting block 5, thereby pushing the mounting block 5 to tilt back and forth; the mounting block 5 drives the POS machine body 3 to tilt back and forth synchronously through the fixed support plate 8 and the L-shaped movable clamp 7 until the appropriate angle is adjusted. If it is necessary to fine-tune the left and right tilt angle of the POS machine body 3, first loosen the positioning screw 605. 9. The positioning screw 609 drives the abutment block 610 to slide downward along the travel groove 608, releasing the clamping and fixing of the abutment block 610 on the connecting ball 607. At this time, the connecting ball 607 can rotate flexibly in the ball socket groove 606, pushing the mounting block 5 to tilt left and right, thereby driving the POS machine body 3 to make slight adjustments to the angle left and right. After the angle adjustment is completed, tighten the positioning screw 609. The positioning screw 609 pushes the abutment block 610 to slide upward along the travel groove 608 until the abutment block 610 is tightly attached to the surface of the connecting ball 607. The friction force fixes the connecting ball 607 in the current position, thereby locking the left and right tilt angle of the POS machine body 3 and ensuring that the angle is stable and does not deviate.

[0028] The complete workflow of this retractable wall-mounted POS machine is as follows: First, the equipment is installed and initially fixed. The wall-mounted base 1 is fixed to the preset position on the wall using expansion bolts and other fasteners to ensure stable support. Then, the POS machine body 3 is placed in the storage frame 2, with its bottom overlapping the fixed support plate 8. At the same time, the connecting posts 9 on both sides of the fixed support plate 8 are embedded into the grooves 10 on both sides of the POS machine body 3. At this time, under the tension of the tension spring 12, the horizontal plate of the L-shaped movable clamping block 7 overlaps the top of the POS machine body 3, and the vertical plate slides down along the connecting groove 11, cooperating with the fixed support plate 8 to initially clamp and fix the POS machine body 3 from the top and bottom sides to prevent shaking. Then, the angle is adjusted as needed. When adjusting the front and rear tilt angle, the bidirectional screw 605 on the outside of the bottom edge of the storage frame 2 is rotated. This drives the two sliders 603 to slide in opposite directions along the slide groove 602. The sliders 603 drive the connecting block 601 to move back and forth through the connecting frame 604. The connecting ball 607 on the front side of the connecting block 601 moves in the ball socket 606 of the mounting block 5, pushing the mounting block 5. Tilt the mounting block 5 and POS machine body 3 back and forth to a suitable angle; when fine-tuning the left and right tilt angle, first loosen the positioning screw 609, so that it drives the abutment block 610 to slide down along the travel groove 608, releasing the fixation of the connecting ball 607, and rotate the connecting ball 607 to drive the mounting block 5 and POS machine body 3 to make slight left and right adjustments. After adjustment, tighten the positioning screw 609, push the abutment block 610 to slide up and press the connecting ball 607 to lock the angle; when in use, pull the closing cover 4 outward of the storage slot 13, so that it rotates around the fixed shaft 16. When block 15 rotates, it causes the limiting strip 14 to slide along the storage groove 13. The torsion spring stores elastic potential energy. When the closing cover 4 rotates to be perpendicular to the opening of the storage frame 2 and the limiting strip 14 slides to the limit position, the closing cover 4 remains open, and the operator can carry out normal transaction operations. After use, push the closing cover 4 inward to the storage groove 13 so that it overcomes the torsion spring force and rotates in the opposite direction, causing the limiting strip 14 to slide back to the initial position. When the closing cover 4 is fully embedded in the storage groove 13, the opening of the storage frame 2 is closed, and the storage of the POS machine body 3 is completed.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
