Description

Technical Field

[0001] This utility model relates to the field of POS machine bracket technology, and in particular to an adjustable telescopic rod structure for POS machine brackets. Background Technology

[0002] In retail and restaurant payment scenarios, POS machines, as core payment devices, need to be positioned to accommodate operators of different heights, different counter layouts, and diverse interaction needs. Traditional POS machine stands are mostly fixed structures, unable to adjust their height and angle according to actual usage scenarios. This forces operators to bend over or raise their arms for extended periods, easily causing fatigue. Furthermore, they are difficult to adapt to the different scanning distances of consumers who are standing or sitting during QR code payments, reducing payment efficiency and user experience.

[0003] To address the limitations of fixed brackets, POS machine brackets with telescopic rods have gradually appeared on the market. However, existing adjustable telescopic rod structures have obvious defects. Most telescopic rods use a threaded adjustment method. Threaded adjustment requires turning the screw block to loosen the telescopic rod. After adjusting to the desired position, the screw block is tightened. The adjustment operation is cumbersome, and after long-term use, it is prone to loosening due to wear, affecting the stability of the bracket. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable telescopic rod structure for a POS machine bracket.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The POS machine bracket has an adjustable telescopic rod structure, including an outer rod. An inner rod is slidably fitted inside the outer rod. A connecting ring is fixedly connected to the inner side of the inner rod near the bottom. A rotating cylinder is fixedly connected to the top center of the connecting ring. A fixing ring is fixedly connected to the top of the rotating cylinder. A thin cylinder is fixedly connected to the top center of the fixing ring. Fixing rods are fixedly connected to both sides of the outer circumference of the thin cylinder. Tension springs are provided on the outer sides of both fixing rods. Two protruding rods are fixedly connected to the inner wall of the inner rod near the tension springs. The other end of each tension spring is connected to the adjacent protruding rod. The tension springs allow the rotating cylinder to quickly return to its original position after rotation and when the hollow button is released. Hollow buttons are slidably fitted on both sides of the top of the inner rod near the thin cylinder. The inner rod has square holes that fit the hollow buttons. One end of each hollow button located inside the inner rod is rotatably connected to an arc-shaped connecting rod. The other ends of the two arc-shaped connecting rods are rotatably connected to the middle of adjacent fixing rods.

[0007] Preferably, the curvature of both of the curved connecting rods is adapted to the thin cylinder.

[0008] Preferably, two first arc-shaped holes are symmetrically opened on the connecting ring, and L-shaped sliding rods are fixedly connected to the bottom of the outer wall of the rotating cylinder near the two first arc-shaped holes.

[0009] Preferably, the inner wall of the inner sleeve rod is symmetrically fixedly connected to a rectangular frame at the bottom of the connecting ring, and a locking block is slidably connected to each of the rectangular frames.

[0010] Preferably, each of the rectangular frames is provided with a second arc-shaped hole, and each card block is provided with an oblique hole. The bottom of each L-shaped slide rod is slidably connected in the adjacent second arc-shaped hole and oblique hole. The card block can be extended or retracted by rotating the L-shaped slide rod.

[0011] Preferably, limit strips are fixedly connected to both sides of the inner wall of the outer sleeve rod, and two slots are symmetrically opened on the inner wall of the outer sleeve rod. Each slot has multiple grooves from top to bottom, and the slots are adapted to the locking blocks.

[0012] Preferably, the outer wall of the inner sleeve rod has two symmetrically arranged limiting grooves, and the limiting grooves are adapted to the limiting strip. The top of the inner sleeve rod is provided with a connector, which can be connected to the clamp of the POS machine. The bottom of the outer sleeve rod is fixedly connected with a base.

[0013] The beneficial effects of this utility model are as follows:

[0014] By employing technologies such as a rotating cylinder, L-shaped slide bar, locking blocks, hollow buttons, curved connecting rods, tension springs, and fixing rods, pressing the hollow button rotates the rotating cylinder, causing the two locking blocks to retract and separate from the slots. This allows the inner sleeve rod to slide freely inside the outer sleeve rod, and releasing it locks it in place. This effectively solves the problems mentioned in the background technology, eliminating the need for cumbersome threaded rotation or being limited by fixed buckle positions. Simply pressing the hollow button unlocks the inner sleeve rod, and releasing it locks it in place. It can be precisely positioned at any height, perfectly adapting to the height requirements of operators of different heights and usage scenarios. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-7The POS machine bracket has an adjustable telescopic rod structure, including an outer rod 1. An inner rod 3 is slidably sleeved on the inner side of the outer rod 1. A connecting ring 6 is fixedly connected to the inner side of the inner rod 3 near the bottom. A rotating cylinder 5 is fixedly connected to the top center of the connecting ring 6. A fixing ring 501 is fixedly connected to the top of the rotating cylinder 5. A thin cylinder 502 is fixedly connected to the top center of the fixing ring 501. Fixing rods 503 are fixedly connected to both sides of the outer circumference of the thin cylinder 502. Tension springs 504 are provided on the outer sides of both fixing rods 503. Two protruding rods are fixedly connected to the inner wall of the inner rod 3 near the tension springs 504. 505, the other end of each tension spring 504 is connected to a protruding rod 505 that is close to it. Hollow buttons 4 are slidably fitted on both sides of the top of the inner sleeve rod 3 near the thin cylinder 502. The hollow buttons 4 are provided with protrusions inside the inner sleeve rod 3 to prevent the hollow buttons 4 from popping out of the inner sleeve rod 3. The inner sleeve rod 3 is provided with square holes that fit the hollow buttons 4. One end of each of the two hollow buttons 4 inside the inner sleeve rod 3 is rotatably connected to a curved connecting rod 401. The other ends of the two curved connecting rods 401 are rotatably connected to the middle of the fixed rods 503 that are close to each other.

[0025] In this invention, the curvature of the two curved connecting rods 401 is adapted to the thin cylinder 502. The curvature of the curved connecting rods 401 allows the thin cylinder 502 to rotate to a greater angle when the hollow button 4 is pressed.

[0026] In this utility model, two first arc-shaped holes 601 are symmetrically opened on the connecting ring 6. An L-shaped slide rod 7 is fixedly connected to the bottom of the outer wall of the rotating cylinder 5 near the two first arc-shaped holes 601. The first arc-shaped holes 601 provide space for the movement of the L-shaped slide rod 7.

[0027] In this utility model, rectangular frames 8 are symmetrically fixedly connected to the inner wall of the inner sleeve rod 3 at the bottom of the connecting ring 6. Each rectangular frame 8 is slidably connected to a locking block 802, and the inner sleeve rod 3 has holes for the locking blocks 802.

[0028] In this utility model, each rectangular frame 8 is provided with a second arc-shaped hole 801, and each locking block 802 is provided with an oblique hole 803. The bottom of each L-shaped slide rod 7 is slidably connected in the adjacent second arc-shaped hole 801 and oblique hole 803. The arrangement of the second arc-shaped hole 801 and oblique hole 803 allows the locking block 802 to move in the rectangular frame 8 when the L-shaped slide rod 7 slides in the second arc-shaped hole 801, thereby achieving the purpose of controlling the extension and retraction of the locking block 802.

[0029] In this utility model, limit strips 101 are fixedly connected to both sides of the inner wall of the outer sleeve rod 1. Two slots 102 are symmetrically opened on the inner wall of the outer sleeve rod 1. Each slot 102 is provided with multiple grooves from top to bottom, and the slots 102 are adapted to the locking blocks 802. Through the cooperation between the locking blocks 802 and the slots 102, the inner sleeve rod 3 can be fixed at any position.

[0030] In this utility model, two limiting grooves 301 are symmetrically opened on the outer wall of the inner sleeve rod 3, and the limiting grooves 301 are adapted to the limiting strip 101. A connector 302 is provided at the top of the inner sleeve rod 3, and a base 2 is fixedly connected to the bottom of the outer sleeve rod 1.

[0031] Working Principle: The base 2, inner sleeve rod 3, outer sleeve rod 1, rotating cylinder 5, and connecting ring 6 of this bracket are all hollow structures, facilitating the passage of wires. The top connector 302 can be connected to the clamp of the POS machine. When the height of the bracket needs to be adjusted, there is no need for traditional tightening, which loosens and tightens the outer sleeve rod 1 and inner sleeve rod 3. Simply press the two hollow buttons 4 with one hand. After being pressed, the two hollow buttons 4 will move closer to the inner sleeve rod 3. Through the push of the curved connecting rod 401, the fixing rod 503, the thin cylinder 502, and the entire rotating cylinder 5 will rotate. At the same time, the two tension springs 504 are stretched. When the hollow buttons 4 are pressed, the rotating cylinder 5 rotates. At this time, the two L-shaped sliding rods 7 at the bottom of the rotating cylinder 5 also rotate. Since the bottom of the L-shaped sliding rod 7 rotates in the second arc hole 801 and the inclined hole 803, when the L-shaped sliding rod 7 rotates along the second arc hole 801, due to the restriction of the inclined hole 803, the locking block 802 retracts into the inner sleeve rod 3, causing the locking block 802 to separate from the slot 102. At this time, the inner sleeve rod 3 can be lifted up or moved down. When the required height is reached, the hollow button 4 is released. Under the reset of the tension spring 504, the two locking blocks 802 can be locked onto the slot 102 again, achieving locking. Compared with the traditional operation of loosening and tightening, this mechanism can be completed with one hand, which is convenient and fast.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
