Description

Technical Field

[0001] The utility model relates to the technical field of retail cabinet monitoring, in particular to a monitoring device for unmanned retail cabinets. Background Art

[0002] With the development of intelligence, traditional closed vending machines have gradually become open-type unmanned vending cabinets. Intelligent unmanned vending cabinets use RFID technology. Electronic tags are attached to commodities, and the tags contain relevant information of the commodities. Users can open the cabinet door by scanning the code through the terminal, and then can freely select commodities. After closing the door, the RFID identification technology can be used to intelligently identify the content of the commodities taken.

[0003] Since vending machines are unmanned on-site controlled machines, there will be cases where criminals steal goods in vending machines. Generally, in order to prevent theft, monitoring is used to remotely control vending machines. The power cords of existing monitoring devices are relatively long and are suspended in the air. If accidentally pulled by someone, the power cords may break or be physically damaged, resulting in damage to the power cords and the monitoring equipment being unable to operate normally.

[0028] The following further explains and illustrates the present utility model in conjunction with specific embodiments.

[0029] As Figures 1-5 shown, a monitoring device for an unmanned retail cabinet provided in this embodiment includes a U-shaped frame 1 and a camera 3 located inside the U-shaped frame 1. Both ends of the camera 3 are fixedly connected with positioning shafts 4, and the ends of the positioning shafts 4 are rotatably inserted into the U-shaped frame 1. A power cord 8 is fixedly connected to the top of the camera 3. A horizontally arranged support plate 12 is fixedly connected to the U-shaped frame 1, and two positioning rods 10 are fixedly connected to the top of the support plate 12. The power cord 8 is wound around the two positioning rods 10, that is, the power cord 8 is wound in a circle from the outside of the two positioning rods 10, so as to achieve the purpose of storing the power cord 8, prevent the power cord 8 from loosening into the air, and avoid damage to the power cord 8 caused by accidental pulling.

[0030] In order to fix the wound power cord 8, a pressing member 9 is provided on the top of the support plate 12. The pressing member 9 is located between the two positioning rods 10, and two jacks 1201 are opened on the top of the support plate 12. The pressing member 9 is cooperatively connected with the jacks 1201.

[0031] Specifically, the pressing member 9 includes a positioning frame 91 and two fixing sleeves 93 fixed to the inner top wall of the positioning frame 91. A plug rod 94 is movably inserted into the fixing sleeve 93. The lower ends of the plug rods 94 are commonly fixedly connected with a pressing plate 96. A spring 95 is fixedly connected between the pressing plate 96 and the fixing sleeve 93. The spring 95 is sleeved on the plug rod 94. Two symmetrically distributed pins 92 are fixedly connected to the bottom of the positioning frame 91. The lower ends of the pins 92 are inserted into the jacks 1201. The pins 92 are of a cylindrical pin structure. The design of the cylindrical pin enables it to provide a very stable connection; once the pins 92 are inserted into the jacks 1201, the cylindrical pins are usually not easily loosened due to shaking or external forces, ensuring the reliability of the connection. The pins 92 are positioned by inserting into the jacks 1201, and the installation and disassembly are relatively simple, with accurate positioning and convenience.

[0032] Two limiting blocks 11 are rotatably connected to the support plate 12. When the positioning frame 91 is fixed, the limiting blocks 11 are pressed against the positioning frame 91. The two limiting blocks 11 press and fix the pressing member 9 to ensure that the pressing member 9 can press and fix the power cord 8.

[0033] During specific operation, wind the power cord 8 around the two positioning rods 10, then insert the plug 92 at the bottom of the positioning frame 91 into the jack 1201, so that the pressing plate 96 is in contact with the surface of the power cord 8, and at this time, the bottom of the positioning frame 91 is in contact with the support plate 12. Rotate the two limit blocks 11 so that the limit blocks 11 are in pressing contact with the positioning frame 91, and at this time, the purpose of fixing the positioning frame 91 is achieved; since the spring 95 is compressed at this time, the spring 95 has elastic potential energy at this time, so that the pressing plate 96 can firmly press and fix the power cord 8; by storing the power cord 8, it is avoided that the power cord 8 is damaged due to accidental pulling.

[0034] In addition, a worm gear 5 is fixedly connected to one end of the positioning shaft 4, and a driving component is fixedly installed on the side wall of the U-shaped frame body 1.

[0035] The driving component includes a motor 7 fixed to the side wall of the U-shaped frame body 1, and a worm 6 is fixedly connected to the output end of the motor 7. The worm 6 is meshed with the worm gear 5.

[0036] Start the motor 7 to drive the worm 6 to rotate. The worm 6 drives the worm gear 5 to rotate. The worm gear 5 drives the camera 3 to rotate through the positioning shaft 4, so as to finely adjust the monitoring range and angle and improve the monitoring effect.

[0037] Furthermore, a bracket 2 is fixedly connected to one end of the U-shaped frame body 1 for connecting to the top of the retail cabinet.

[0038] One end of the bracket 2 away from the U-shaped frame body 1 is provided with a mounting hole. By arranging fasteners in the mounting hole, it is connected to the preset screw holes at the top of the retail department.

[0039] The pressing plate 96 is of a flat plate structure, and a rubber pad is arranged at the bottom of the pressing plate 96. The rubber pad can effectively fix the position of the power cord 8. The rubber material can relieve the friction on the power cord 8 to a certain extent, thereby prolonging the service life of the power cord 8 and avoiding damage to the wire due to friction.

[0040] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
