Abstract
Description
Technical Field
[0001] This utility model relates to a dual-degree-of-freedom concealed hook structure, belonging to the field of multi-functional terminal readers. Background Technology
[0002] A POS machine is also a multi-functional terminal reader, which is a terminal reader equipped with barcode or OCR code technology. It has cash or barter credit card disbursement functions. It is installed in credit card merchants and acceptance outlets and connected to a computer network. When using a POS machine, you can hold the POS machine itself or attach it to a POS machine base and place it on the cashier counter.
[0003] POS machine stands are divided into universal stands and locking stands. Universal stands are traditional charging stands, where the POS machine can be freely removed. This design emphasizes convenience. However, due to the flexible structure, the connection between the POS machine and the stand is weak, and the POS machine may fall off the stand due to shaking or collision, resulting in a drop. Locking stands, on the other hand, fix the POS machine to the stand and prevent it from being freely removed. They are used as desktop stands. Because locking stands have an additional fixed interface compared to universal stands, they are generally only suitable for scenarios where the POS machine cannot be freely removed, and cannot accommodate the flexible or convenient switching between the two scenarios.
[0004] Therefore, this utility model provides a dual-degree-of-freedom hidden hook structure that improves the flexibility and ease of adjustment between the POS machine base and the POS machine. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide a two-degree-of-freedom concealed hook structure to solve the above problems.
[0006] This utility model is implemented as follows:
[0007] A dual-degree-of-freedom concealed hook structure includes a POS machine base, a POS machine, and a hook. The POS machine base is provided with an inclined receiving groove for placing the POS machine. A first sliding groove is opened in the middle part or at the bottom of the receiving groove in the POS machine base. The hook moves in the first sliding groove so that the POS machine can be detachably and fixedly connected in the receiving groove.
[0008] As a further improvement, this utility model also includes a spring, a carrier, a cover plate, and a ramp block. The cover plate is located on the back of the POS machine base, and a ramp block is provided on the back of the POS machine base. The upper and lower end faces of the carrier are respectively slidably engaged with the back of the POS machine base and the cover plate. One end of the hook is exposed in the receiving groove, and the other end is connected to the carrier by a spring.
[0009] As a further improvement, a sliding button is fixed at the bottom of the carrier, and a second sliding groove is provided on the cover plate. The free end of the sliding button passes through the second sliding groove and is exposed outside the POS machine base.
[0010] When the slider is moved to one side, the carrier moves the hook to that side, the hook is guided to the bottom of the ramp block and is in a hidden state, the spring is in a compressed state, and the POS machine is in a free state in the POS machine base;
[0011] Alternatively, by moving the slider to the other side, the carrier moves the hook to that side, guiding the hook to a raised position on the top of the ramp block, where the spring is extended. The hook then engages with the POS machine to achieve a locking state between the POS machine and its base.
[0012] As a further improvement, the carrier includes a vertical section and two elastic arms arranged in parallel, with one end of each elastic arm fixed to the top of the vertical section.
[0013] As a further improvement, the first slide groove on the back of the POS machine base is provided with limiting ribs on both sides, and the elastic arm cooperates with the limiting ribs.
[0014] As a further improvement, the carrier and the cover plate are slidably fitted together by a sliding structure.
[0015] As a further improvement, the sliding structure includes a third groove and a protrusion corresponding to the outer contour of the third groove, the third groove sliding horizontally on the protrusion so that the carrier and the cover plate slide together.
[0016] As a further improvement, the sliding structure includes a second protrusion and a fourth sliding groove formed by two parallel second protrusions, wherein the second protrusion slides horizontally in the fourth sliding groove so that the carrier and the cover plate slide together.
[0017] As a further improvement, the third sliding groove is provided on the bottom end face of the carrier, and a protrusion is provided on one end face of the cover plate. The third sliding groove slides on the protrusion so that the carrier and the cover plate slide together.
[0018] Alternatively, the third sliding groove is provided on one end face of the cover plate, and the bottom end face of the carrier is provided with a protrusion. The third sliding groove slides on the protrusion so that the carrier and the cover plate slide together.
[0019] As a further improvement, the second protrusion is provided on the bottom end face of the carrier, and the fourth sliding groove is provided on one end face of the cover plate. The second protrusion slides horizontally in the fourth sliding groove so that the carrier and the cover plate slide together.
[0020] Alternatively, the second protrusion is located on one end face of the cover plate, and the fourth sliding groove is located on the bottom end face of the carrier. The second protrusion slides horizontally in the fourth sliding groove so that the carrier and the cover plate slide together.
[0021] The beneficial effects of this utility model are as follows: The hook of this utility model can be set in the middle part of the POS machine base or the bottom has a first sliding groove. It can fix the POS machine on the POS machine base and use it as a desktop computer. The POS machine is removed from the POS machine base less frequently, which improves the stability of the POS machine base for charging or communication.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0036] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0037] Example 1
[0038] Reference Figures 1 to 6 As shown, this embodiment provides a specific implementation of a dual-degree-of-freedom hidden hook structure, including a POS machine base 10, a POS machine 20, and a hook 30. The POS machine base 10 is provided with an inclined receiving groove 101 for placing the POS machine 20. The bottom of the receiving groove 101 in the POS machine base 10 has a first sliding groove 102. The hook 30 moves in the first sliding groove 102 so that the POS machine 20 can be detachably and fixedly connected in the receiving groove 101.
[0039] In the above technical solutions, this utility model can not only fix the POS machine 20 on the POS machine base 10 through the hook 30 to be used as a desktop computer, but also reduce the frequency of taking the POS machine off the POS machine base 10, thereby improving the stability of charging or communication of the POS machine base 10. In addition, the hook 30 can be hidden, making it more convenient to take the POS machine off the POS machine base 10. In other words, this utility model combines multiple bases into one adjustable POS machine base 10, which greatly reduces costs and improves convenience.
[0040] In this embodiment, the specific structure and principle of the POS machine 20 being detachably and fixedly connected to the POS machine base 10 are as follows:
[0041] The present invention also includes a spring 40, a carrier 50, a cover plate 60, and a ramp block 70. The cover plate 60 is located on the back of the POS machine base 10, and the ramp block 70 is provided on the back of the POS machine base 10. The upper and lower end faces of the carrier 50 are respectively slidably engaged with the back of the POS machine base 10 and the cover plate 60. One end of the hook 30 is exposed in the receiving groove 101, and the other end is connected to the carrier 50 by the spring 40.
[0042] Furthermore, a sliding button 501 is fixed at the bottom of the carrier 50, and a second sliding groove 601 is provided on the cover plate 60. The free end of the sliding button 501 passes through the second sliding groove 601 and is exposed outside the POS machine base 10.
[0043] So that when the slider 501 is moved to one side, the carrier 50 drives the hook 30 to move to that side, the hook 30 is guided to the bottom of the ramp block 70 and is in a hidden state, the spring 40 is in a compressed state, and the POS machine is in a free state in the POS machine base 10.
[0044] Alternatively, by moving the slider 501 to the other side, the carrier 50 moves the hook 30 to that side, and the hook 30 is guided to the top of the ramp block 70 in a raised state, the spring 40 is in an extended state, and the hook 30 cooperates with the POS machine 20 to achieve the locking state of the POS machine 20 and the POS machine base 10.
[0045] In the above technical solution, the free state and locked state of the hook 30 can be switched by moving the slider 501 left and right. The operation is simple and the state switching is also quick.
[0046] In this embodiment, the carrier 50 includes a vertical part 503 and elastic arms 502. There are two elastic arms 502 arranged in parallel, and one end of each elastic arm 502 is fixed to the top of the vertical part 503.
[0047] Furthermore, the first slide groove 102 on the back of the POS machine base 10 is provided with limiting ribs 103 on both sides, and the elastic arm 502 cooperates with the limiting ribs 103.
[0048] In the above technical solution, when the hook 30 is at one end of the first slide groove 102, that is, the extreme position, the elastic arm 502 and the limiting rib 103 have motion interference to ensure that the hook is in a stable state when the sliding button is not operated. However, as long as a force is applied to the sliding button 501, the elastic arm 502 of the carrier 50 deforms and slides past the limiting rib 103, causing the hook 30 to move to another state.
[0049] In this embodiment, the carrier 50 and the cover plate 60 are slidably engaged through a sliding structure. There are two types of sliding structures, and in practical applications, either one can be used, as long as it allows the carrier 50 and the cover plate 60 to slide and engage with each other.
[0050] The first type of sliding structure includes a third sliding groove 504 and a protrusion 602 corresponding to the outer contour of the third sliding groove 504. The third sliding groove 504 slides horizontally on the protrusion 602 so that the carrier 50 and the cover plate 60 slide together.
[0051] Specifically, the third sliding groove 504 is provided on the bottom end face of the carrier 50, and a protrusion 602 is provided on one end face of the cover plate 60. The third sliding groove 504 slides on the protrusion 602 so that the carrier 50 and the cover plate 60 are slidably engaged; or, the third sliding groove 504 is provided on one end face of the cover plate 60, and a protrusion 602 is provided on the bottom end face of the carrier 50. The third sliding groove 504 slides on the protrusion 602 so that the carrier 50 and the cover plate 60 are slidably engaged.
[0052] The second sliding structure includes a second protrusion 603 and a fourth sliding groove 505 formed by two parallel second protrusions 603. The second protrusion 603 slides horizontally in the fourth sliding groove 505 so that the carrier 50 and the cover plate 60 slide together.
[0053] Specifically, the second protrusion 603 is disposed on the bottom end face of the carrier 50, and the fourth sliding groove 505 is disposed on one end face of the cover plate 60. The second protrusion 603 slides horizontally in the fourth sliding groove 505 so that the carrier 50 and the cover plate 60 are in sliding engagement; or, the second protrusion 603 is disposed on one end face of the cover plate 60, and the fourth sliding groove 505 is disposed on the bottom end face of the carrier 50. The second protrusion 603 slides horizontally in the fourth sliding groove 505 so that the carrier 50 and the cover plate 60 are in sliding engagement.
[0054] Example 2
[0055] See Figures 7 to 11 As shown, the difference from Embodiment 1 is that the installation position of the hook is different. In this embodiment, the hook is installed in the middle part of the receiving groove 101 in the POS machine base 10 or in the bottom where the first sliding groove 102 is opened. The hook 30 moves in the first sliding groove 102 so that the POS machine 20 can be detachably and fixedly connected to the receiving groove 101. The cover plate 60 is located on the back of the POS machine base 10. The installation position of the hook can be selected according to the requirements.
[0056] It should be noted that this embodiment is the same as the first embodiment in terms of implementation principle and technical effect. For the sake of brevity, the implementation form and structure of the remaining structures of this embodiment are roughly the same as those of the first embodiment, and will not be repeated here.
[0057] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
