Description

Technical Field

[0001] This utility model relates to the field of needle life testing technology, specifically a needle life tester for clothing anti-theft buckles. Background Technology

[0002] Anti-theft tags, widely used security devices in the retail industry, are commonly found in various clothing stores. Their structure generally consists of a lock cylinder, steel balls, springs, and other components. They are firmly fixed to clothing through special mechanical principles. When clothing with anti-theft tags passes through the security gate of a shopping mall without being unlocked, the tags will trigger an alarm to prevent theft. The needle is a tool specifically used to open anti-theft tags. It usually consists of a slender needle and a handle that is easy to grip. The tip of the needle is ingeniously designed to accurately insert into the lock cylinder of the anti-theft tag. Through specific operations, it pushes open the steel balls and compresses the spring, thereby unlocking the anti-theft tag.

[0003] Currently available pins on the market often experience wear, deformation, or even breakage during frequent use due to factors such as materials and structural design. This prevents the pins from properly opening the anti-theft tag, causing inconvenience to both merchants and consumers. Merchants need to regularly inspect and replace the pins, which undoubtedly increases operating costs and manpower. However, current methods for testing the lifespan of pins are extremely limited. In most cases, employees can only rely on their experience to judge whether the pins are damaged by observing whether there is obvious wear or deformation on the appearance of the pins, or by feeling whether the pins open the anti-theft tag smoothly during actual operation. This method is highly subjective, has low accuracy, and makes it difficult to accurately determine the actual lifespan of the pins or quantify their number of uses. In view of this, we propose a pin lifespan tester for clothing anti-theft tags. Utility Model Content

The lifting rod moves up and down under the action of the screw, realizing the repeated insertion and removal of the needle. At the same time, the cooperation of the counter, photoelectric sensor, LED light and light shield achieves the effect of accurately counting the number of needle insertion and removal, so as to accurately test the life of the needle. There is no need to manually insert and remove the needle for life testing, which saves time and effort.

[0018] 3. This utility model achieves stable support for the entire testing instrument through the setting of support columns, support plates and anti-slip plates.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-9 This utility model provides a technical solution: a needle removal life tester for clothing anti-theft buckles, including a working plate 1, an anti-theft buckle 5, and a needle removal device 7. Several support columns 2 are fixed to the bottom of the working plate 1. A control panel 9 is installed on the top surface of the working plate 1. The anti-theft buckle 5 is placed in the middle of the top surface of the working plate 1. A clamping mechanism 6 for limiting the anti-theft buckle 5 is provided on the top surface of the working plate 1. The clamping mechanism 6 includes two fixed plates 61 fixed to the top surface of the working plate 1 near the rear end, two connecting columns 62 rotatably connected to the fixed plates 61 on the same side, a bidirectional lead screw 63 coaxially fixed between the two connecting columns 62 and arranged laterally, two clamping plates 64 threadedly connected to the bidirectional lead screw 63 and used to clamp the anti-theft buckle 5, and a clamping motor 67 installed on the surface of one of the fixed plates 61 away from the bidirectional lead screw 63, with its output shaft coaxially connected to the connecting column 62 on the same side. The two clamping plates 64 are symmetrical to each other and are slidably connected to the top surface of the working plate 1. The device also includes:

[0032] Test mechanism 8, set on the top surface of work plate 1, is used to test the lifespan of needle retrieval 7. Test mechanism 8 includes a frame 81 fixed to the top surface of work plate 1 and arranged horizontally, a rotating column 82 rotatably connected to the horizontal end of frame 81, a rotating roller 83 rotatably connected to the top surface of work plate 1, a screw 84 coaxially fixed between rotating roller 83 and rotating column 82 and arranged vertically, a lifting rod 85 threaded to screw 84 and shaped like an L, and a mounting plate 87 fixed to the bottom surface of the vertical end of lifting rod 85. Needle retrieval 7 is compatible with anti-theft buckle 5 and detachably mounted on the bottom surface of mounting plate 87. Lifting rod 85 is slidably connected to the right outer wall of the left vertical end of frame 81. A counter 813 and a photoelectric sensor 814 are installed on the left outer wall of the right vertical end of frame 81, arranged from top to bottom. An LED light 815 corresponding to the position of photoelectric sensor 814 is installed on the right surface of the left vertical end of frame 81. The front surface of the test mechanism 8 is fixed with a light shield 816 to block the light emitted by the LED light 815. The test mechanism 8 also includes a test motor 810 mounted on the top surface of the horizontal plate of the frame 81 to drive the rotating column 82 to rotate. Through the clamping mechanism 6 on the work plate 1, a stable clamping and limiting of the anti-theft buckle 5 is achieved. Specifically, the clamping motor 67 drives the bidirectional lead screw 63 to rotate, causing the two clamping plates 64 to move closer or further apart, thus adapting to anti-theft buckles 5 of different sizes. This improves the stability of the anti-theft buckle 5 during testing and ensures the accuracy of the test data. The test mechanism 8 enables the detachable installation of the needle retrieval 7 and its repeated lifting and lowering. The test motor 810 drives the rotating column 82 to rotate via gear 89, which in turn rotates the screw 84. The lifting rod 85 moves up and down under the action of the screw 84, realizing the repeated insertion and removal of the needle retrieval 7. Simultaneously, the counter 813, photoelectric sensor 814, and LED... The combination of lamp 815 and light shield 816 achieves the effect of accurately counting the number of times the needle 7 is inserted and removed, thus enabling accurate testing of the lifespan of the needle 7 without the need for manual insertion and removal for lifespan testing, saving time and effort.

[0033] In this embodiment, the testing mechanism 8 also includes a rotating rod 88 coaxially fixed on the top surface of the rotating column 82, two gears 89 located above the horizontal plate end of the frame 81 and meshing with each other, and a rotating shaft 811 coaxially connected to the output shaft of the testing motor 810. The two gears 89 are respectively coaxially fixed on the outer circumference of the rotating shaft 811 and the rotating rod 88, so that the testing motor 810 can stably drive the rotating column 82 to rotate through the transmission of the rotating shaft 811 and the gears 89, thus ensuring the stability of the operation of the testing mechanism 8.

[0034] In addition, a guide groove is provided on the right side surface of the left vertical plate end of the frame 81, and a guide block 86 is fixed on the left side surface of the horizontal bar end of the lifting rod 85, which is slidably connected to the guide groove on the outer wall of the left vertical plate end of the frame 81. A horizontally arranged sliding groove is provided on the top surface of the working plate 1. The clamping plate 64 is L-shaped, and a slider 65 is fixed on the bottom surface of the vertical plate end of the clamping plate 64, which is slidably connected to the sliding groove on the top surface of the working plate 1. By providing a guide groove on the right side surface of the left vertical plate end of the frame 81 and fixing a guide block 86 slidably connected to the guide groove on the left side surface of the horizontal bar end of the lifting rod 85, the lifting rod 85 can slide stably along the guide groove during the lifting process, thus improving the stability of the lifting rod 85. By providing a sliding groove on the top surface of the working plate 1 and fixing a slider 65 slidably connected to the sliding groove on the bottom surface of the vertical plate end of the clamping plate 64, the clamping plate 64 can slide stably along the sliding groove when clamping the anti-theft buckle 5, thus improving the stability of the movement of the clamping plate 64.

[0035] Furthermore, the needle retrieval 7 includes a needle 71 located directly above the anti-theft buckle 5. The bottom end of the needle 71 is fixed with a needle tube 72 that corresponds to the position of the anti-theft buckle 5 and is adapted in size. The bottom surface of the mounting plate 87 is provided with a threaded hole, and the outer circumference of the needle 71 is provided with an external thread that is adapted to the threaded hole on the bottom surface of the mounting plate 87. The needle 71 is threadedly connected to the threaded hole on the bottom surface of the mounting plate 87, and the position of the light shield 816 corresponds to the position of the LED light 815 and is adapted in size, so that the needle retrieval 7 can be easily installed on the bottom surface of the mounting plate 87, realizing the detachable installation of the needle retrieval 7, which facilitates the replacement of different needle retrieval 7s. The light shield 816 can accurately block the light emitted by the LED light 815, ensuring that the photoelectric sensor 814 can accurately detect the number of times the lifting rod 85 is raised and lowered, so that the counter 813 can accurately count.

[0036] Specifically, a support plate 3 is fixed to the bottom of the support column 2, and an anti-slip plate 4 that matches the shape of the support plate 3 is fixed to the bottom of the support plate 3. The thickness of the anti-slip plate 4 is 2-5cm, preferably 3cm in this paper, so that the tester is more stable when placed on a flat surface, preventing the tester from sliding and improving the safety and stability of the tester during use.

[0037] It is worth noting that a placement groove is provided in the middle of the top surface of the working plate 1. A placement pad 10 of the same size is fixed inside the placement groove on the top surface of the working plate 1. The anti-theft buckle 5 is located on the top surface of the placement pad 10. Protective plates 66 are fixed on the opposite sides of the horizontal ends of the two clamping plates 64. The side surface of the protective plate 66 away from the clamping plate 64 on the same side is in close contact with the outer wall of the anti-theft buckle 5 on the same side. By setting a placement groove in the middle of the top surface of the working plate 1 and fixing the placement pad 10, the anti-theft buckle 5 can be placed on the placement pad 10, which plays a certain protective role for the anti-theft buckle 5. By fixing the protective plate 66 on the opposite sides of the horizontal ends of the two clamping plates 64, and the side surface of the protective plate 66 away from the clamping plate 64 on the same side is in close contact with the outer wall of the anti-theft buckle 5 on the same side, the protective plate 66 can protect the anti-theft buckle 5 from being pinched by the clamping plate 64 when the anti-theft buckle 5 is clamped, thus further protecting the anti-theft buckle 5.

[0038] It is worth noting that the clamping mechanism 6 also includes a motor box 68 fixed to the surface of one of the fixed plates 61 away from the bidirectional lead screw 63. The clamping motor 67 is located inside the motor box 68. The testing mechanism 8 also includes a protective box 812 fixed to the top surface of the horizontal plate end of the frame 81. The testing motor 810 is located inside the protective box 812, and the rotating shaft 811 passes through the top surface of the protective box 812, which protects the clamping motor 67 and prevents dust and other impurities from entering and affecting the normal operation of the clamping motor 67. At the same time, it also protects the testing motor 810 and prevents the testing motor 810 from being affected by external factors, thus ensuring the normal operation of the testing motor 810.

[0039] It is worth emphasizing that the cross-sectional shape of the guide groove on the right side surface of the left vertical plate end of the frame 81 is convex, and the shape of the guide block 86 is convex, which matches the shape of the guide groove on the outer wall of the left vertical plate end of the frame 81. This makes the guide block 86 more stable when sliding in the guide groove, prevents the guide block 86 from falling out of the guide groove, and further improves the stability of the lifting rod 85.

[0040] It should be added that the clamping motor 67, the test motor 810, the counter 813, the photoelectric sensor 814, and the LED light 815 are all electrically connected to the control panel 9 via wires. The clamping motor 67, the test motor 810, the counter 813, the photoelectric sensor 814, and the LED light 815 are all electrically connected to an external power supply via wires, and the control panel 9 is also electrically connected to an external power supply via wires.

[0041] Finally, it should be noted that the clamping motor 67, test motor 810, counter 813, photoelectric sensor 814, LED light 815, control panel 9, anti-theft buckle 5, needle retrieval 7, and other components involved in this utility model are all general standard parts or components known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0042] In this embodiment, during the actual use, the anti-theft buckle 5 is first placed on the placement pad 10 in the placement groove in the middle of the top surface of the work plate 1. The placement pad 10 can play a certain protective role for the anti-theft buckle 5. The needle 71 of the needle 7 is threadedly connected to the threaded hole on the bottom surface of the mounting plate 87 through the external thread of its outer circumference, so that the needle 7 can be detachably installed on the mounting plate 87. The needle tube 72 of the needle 7 corresponds to the anti-theft buckle 5 in position and is adapted in size.

[0043] Next, the operator starts the clamping motor 67 via the control panel 9. The output shaft of the clamping motor 67 drives the connecting column 62, which is coaxially connected to it, to rotate. The connecting column 62 drives the bidirectional lead screw 63 to rotate. Since the two clamping plates 64 are threadedly connected to the bidirectional lead screw 63, and the slider 65 on the bottom surface of the vertical plate end of the clamping plate 64 slides in the groove on the top surface of the work plate 1, the rotation of the bidirectional lead screw 63 causes the two clamping plates 64 to move closer to each other along the groove until the protective plate 66 on the opposite side of the horizontal plate end of the clamping plate 64 tightly abuts against the outer wall of the anti-theft buckle 5, thereby clamping and limiting the anti-theft buckle 5. The protective plate 66 can prevent the anti-theft buckle 5 from being pinched and damaged.

[0044] Then, the operator starts the test motor 810, counter 813, photoelectric sensor 814 and LED light 815 through the control panel 9. The output shaft of the test motor 810 drives the rotating shaft 811 to rotate. The gear 89 on the rotating shaft 811 meshes with the gear 89 on the rotating rod 88, thereby driving the rotating rod 88 and the rotating column 82 fixed on the same axis to rotate. When the rotating column 82 rotates, it drives the screw 84 fixed on the same axis to rotate. The screw 84 is threadedly connected to the lifting rod 85, and the guide block 86 on the left side of the horizontal end of the lifting rod 85 slides in the guide groove on the right side of the left vertical plate end of the frame 81. The convex design of the guide groove and the guide block 86 ensures the stability of the lifting rod 85. The rotation of the screw 84 causes the lifting rod 85 to move up and down along the guide groove. The lifting rod 85 drives the mounting plate 87 and the needle retrieval 7 to move up and down, so that the needle retrieval 7 repeatedly inserts and pulls out the anti-theft buckle 5, simulating the working situation of the needle retrieval 7 in actual use.

[0045] During the lifting and lowering process of the lifting rod 85, the light shield 816 on the front surface of its vertical end moves with the lifting rod 85. When the light shield 816 passes the LED light 815, it blocks the light emitted by the LED light 815. The photoelectric sensor 814 detects the change in light and transmits the signal to the counter 813. The counter 813 counts once. As the needle 7 is repeatedly inserted and removed, the light shield 816 continuously blocks and releases the light of the LED light 815, and the counter 813 continues to count, thereby recording the number of insertions and removals of the needle 7. When the preset number of test times is reached or the needle 7 is damaged, the operator can stop the test motor 810 and the clamping motor 67 through the control panel 9, release the clamp 64, remove the anti-theft buckle 5 and the needle 7, and evaluate the life of the needle 7 based on the number of times recorded by the counter 813.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
