Abstract
Description
Technical Field
[0001] This utility model relates to the field of vending machine technology, and in particular to anti-theft devices and vending machines. Background Technology
[0002] Vending machines are commonly used equipment in commercial automation. They are not limited by time or location, save manpower, and facilitate transactions, representing a new form of commercial retail, often referred to as 24-hour mini-supermarkets. Furthermore, with market changes, vending machines have evolved into various styles, such as those equipped with anti-theft pushers.
[0003] In vending machines, there are various anti-theft devices, including rotating anti-theft devices, fixed anti-theft devices that move up and down with the elevator, and horizontally moving anti-theft pushers, among which horizontally moving anti-theft pushers are the most common. In order to save space for the anti-theft pusher, the independent module of the anti-theft pusher needs to be made "thin" and run smoothly. Dual synchronous belt drive is the most reliable, which involves the issue of synchronous belt tension. The existing synchronous belt tensioning is generally achieved by pressing with eccentric pulleys or eccentric rollers. This method is laborious to assemble and the tension of the synchronous belt cannot be adjusted later. Summary of the Invention
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-theft device and a vending machine to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, in a first aspect, this utility model provides an anti-theft device, including a mounting base, a motor, a transmission mechanism, and an anti-theft push plate;
[0006] The motor and the transmission mechanism are respectively mounted on the mounting base;
[0007] The anti-theft push plate is installed at the output end of the conveying mechanism, and the conveying mechanism is used to drive the anti-theft push plate to move.
[0008] The transmission mechanism includes a timing pulley, an adjusting pulley, a timing belt, an adjusting seat, and an adjusting assembly;
[0009] The synchronous pulley and the adjusting seat are respectively mounted on the mounting base;
[0010] The motor is connected to the synchronous pulley drive;
[0011] The adjusting wheel is mounted on the adjusting seat;
[0012] The timing belt is fitted between the timing pulley and the adjusting pulley;
[0013] The adjustment component is mounted between the mounting base and the adjustment base, and is used to adjust the distance between the adjustment wheel and the synchronous wheel;
[0014] The anti-theft push plate is installed on the synchronous belt.
[0015] Furthermore, a synchronous shaft is mounted on the mounting base, the motor is connected to the synchronous shaft for transmission, and the synchronous pulley is mounted on the synchronous shaft.
[0016] Furthermore, the transmission mechanism is provided in two sets, and the synchronous pulleys of the two sets of transmission mechanisms are respectively installed at both ends of the synchronous shaft.
[0017] Furthermore, the adjusting assembly includes a nut and a screw, the nut being mounted on the adjusting seat and passing through the mounting seat; the screw is threadedly connected to the nut and abuts against the mounting seat.
[0018] Furthermore, at least two adjustment components are provided.
[0019] Furthermore, the mounting base has a guide hole, and the adjusting base has a guide portion that extends into the guide hole.
[0020] Furthermore, a reinforcing plate is installed at the corner of the mounting base.
[0021] Furthermore, the reinforcing plate is provided with a limiting part, which is used to limit the anti-theft push plate.

[0040] Example 1
[0041] The anti-theft device includes a mounting base 1, a motor 2, a transmission mechanism 3, and an anti-theft push plate 4;
[0042] The motor 2 and the transmission mechanism 3 are respectively mounted on the mounting base 1;
[0043] The anti-theft push plate 4 is installed at the output end of the transmission mechanism 3, and the transmission mechanism 3 is used to drive the anti-theft push plate 4 to move.
[0044] The transmission mechanism 3 includes a synchronous pulley 301, an adjusting pulley 302, a synchronous belt 303, an adjusting seat 304, and an adjusting assembly 305;
[0045] The synchronous pulley 301 and the adjusting seat 304 are respectively mounted on the mounting seat 1;
[0046] The motor 2 is connected to the synchronous pulley 301 in a transmission connection;
[0047] The adjusting wheel 302 is mounted on the adjusting seat 304;
[0048] The timing belt 303 is sleeved between the timing pulley 301 and the adjusting pulley 302;
[0049] The adjustment component 305 is installed directly between the mounting base 1 and the adjustment base 304, and is used to adjust the distance between the adjustment wheel 302 and the synchronous wheel 301.
[0050] The anti-theft push plate 4 is installed on the synchronous belt 303.
[0051] In this embodiment, when installing the timing belt 303, the position of the adjusting seat 304 is first adjusted by the adjusting component 305 to bring the distance between the adjusting wheel 302 and the timing wheel 301 closer, which facilitates the installation of the timing belt 303. After the timing belt 303 is installed, the position of the adjusting seat 304 is adjusted by the adjusting component 305 to bring the distance between the adjusting wheel 302 and the timing wheel 301 further apart, and the timing belt 303 is tensioned. This tensioning method is simpler to install than the tensioning method using eccentric wheels or eccentric rollers in the prior art, and the user can adjust the tension of the timing belt 303 at any time later. The anti-theft push plate 4 has an initial position and an anti-theft position. The motor 2 drives the timing wheel 301 to rotate, thereby driving the anti-theft push plate 4 to move through the timing belt 303, so that the anti-theft push plate 4 is in the initial position or the anti-theft position.
[0052] Furthermore, a synchronous shaft 5 is mounted on the mounting base 1, the motor 2 is connected to the synchronous shaft 5 for transmission, and the synchronous pulley 301 is mounted on the synchronous shaft 5.
[0053] Furthermore, the transmission mechanism 3 is provided in two sets, and the synchronous pulleys 301 of the two sets of transmission mechanisms 3 are respectively installed at both ends of the synchronous shaft 5.
[0054] In this embodiment, by setting two sets of conveying mechanisms 3, the support for the anti-theft push plate 4 is better. Of course, in other embodiments, more sets of conveying mechanisms 3 can be set according to the width of the anti-theft push plate 4.
[0055] Furthermore, the adjusting assembly 305 includes a nut 3051 and a screw 3052. The nut 3051 is installed on the adjusting seat 304 and passes through the mounting seat 1. The screw 3052 is threadedly connected to the nut 3051 and abuts against the mounting seat 1.
[0056] Furthermore, at least two adjustment components 305 are provided.
[0057] In this embodiment, the position of the mounting base 1 is adjusted by the cooperation of the nut 3051 and the screw cap 3052. The structure is simple, and the user can adjust the tension of the timing belt 303 at any time by tightening the screw cap 3052.
[0058] Furthermore, the mounting base 1 is provided with a guide hole 101, and the adjusting base 304 is provided with a guide part 3041, which extends into the guide hole 101.
[0059] In this embodiment, by providing a guide hole 101, the guide part 3041 extends into the guide hole 101, which can guide and limit the adjustment seat 304, and prevent the adjustment seat 304 from swaying.
[0060] Furthermore, a reinforcing plate 6 is installed at the corner of the mounting base 1.
[0061] Furthermore, the reinforcing plate 6 is provided with a limiting part 601, which is used to limit the anti-theft push plate 4.
[0062] In this embodiment, the reinforcing plate 6 not only strengthens the mounting base 1, but the limiting part 601 on the reinforcing plate 6 also limits the anti-theft push plate 4. When the anti-theft push plate 4 is in the initial position, it abuts against the limiting part 601. It should be noted that when the anti-theft push plate 4 is in the anti-theft position, it abuts against the vending machine cabinet.
[0063] Furthermore, the mounting base 1 is provided with a guide rail 7, and the anti-theft push plate 4 is provided with a guide wheel 8, which cooperates with the guide rail 7.
