Description

Technical Field

[0001] The utility model relates to the technical field of vending machines, in particular to an auxiliary pull rod device of a vending machine. Background Art

[0002] A vending machine is a machine that can automatically pay for goods according to the coins inserted. It is a common equipment in commercial automation and is not restricted by time or place. It is a new form of commercial retail. Since the space between the vending machine window and the material channel is relatively narrow, the falling goods are easily stuck in the space between the vending machine window and the material channel, resulting in normal delivery. Auxiliary pull rod devices are now often used to complete the blockage work. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a vending machine auxiliary pull rod device and a vending machine with a publication number of CN211044388U, comprising a pull rod, a fixed pulley, a reel, a slider, a slide rail, a pulley, a pulley support, a pulley shaft, a bearing, a nut, a reel cylinder, a first support, an outlet plate, a reel cylinder shaft, a nut, a second support and a reel base. The auxiliary pull rod is arranged in the vending machine window, and a reserved handle is arranged outside the window. When the product is stuck during the delivery process, the handle is manually pulled to make the auxiliary pull rod fall, and the product is pushed to fall and fall into the discharge port normally; consumers can eliminate the problem of the product being stuck by themselves, It avoids the loss of consumers and can reduce the maintenance work of maintenance personnel; the end of the pull rod is equipped with multiple sliders, and multiple sliders are used to cooperate with the same slide rail at the same time, so that the sliders can assist each other, improve the stability of the pull rod in the process of sliding along the track, and avoid the sliding jamming problem caused by the offset force of a single slider; a reel is used in conjunction with a torsion spring to form a self-restoring winding mechanism. When using the pull rod, the external force only needs to operate the pull rod to slide downward to push out the stuck product. The reel and the torsion spring can drive the pull rod to rise and restore the initial position, waiting for the next use, which can more conveniently meet the use needs.

[0004] The above utility model needs to set a reserved handle outside the window to facilitate consumers to hold the reserved handle with the same hand and move it down. The design of this structure needs to open a through groove structure on one side of the vending machine to reserve space for the up and down movement of the reserved handle. The design of the through groove structure makes it easy for external dust or impurities to enter the interior of the vending machine. The contact of goods with dust or impurities will affect the cleanliness and reduce the practicality of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

In this process, external dust or impurities cannot enter the interior of the vending machine casing. The right-angle plate serves to install the connecting shaft. The installation cover prevents foreign objects from contacting the first bevel gear and the second bevel gear. The vertical rod ensures the stability of the up and down movement of a group of convex sliders on the right. By setting the built-in convex slide groove and convex slider, external dust or impurities can be prevented from entering the vending machine without affecting the clearing work, thereby improving the practicality of the auxiliary pull rod device of the vending machine.

[0020] (2) The utility model adopts a lifting plate. According to the above operation, the pull rod that moves up and down can clear the stuck goods. The goods will eventually fall on the upper part of the lifting plate. The lifting plate will squeeze the two sets of telescopic springs through the two sets of connecting rods and the moving plate. When the moving plate presses the push switch, the buzzer alarm starts to work. Consumers can know through the buzzer alarm whether the blocked goods have been cleared. The two sets of filters can ensure that the sound of the buzzer alarm can be transmitted to the inside of the covering cover. The setting of the lifting plate can help consumers know whether the blocked goods have been cleared, thereby adding a prompt alarm function to the auxiliary pull rod device of the vending machine.

[0038] Working principle:

[0039] When the auxiliary pull rod device of the vending machine is actually used, the consumer holds a group of rubber columns 15 with his hands and then lifts his feet off the ground. At this time, the consumer's weight will act on this group of rubber columns 15, and this group of rubber columns 15 will drive the transmission belt 14 to rotate and move downward. During this process, the transmission belt 14 will drive the two groups of pulleys 13 to rotate, and the lower group of pulleys 13 will drive the second bevel gear 18 to rotate through the mounting shaft 10. Since the first bevel gear 17 and the second bevel gear 18 are meshed with each other, the rotating second bevel gear 18 can push the first bevel gear 17 to rotate, and the rotating first bevel gear 17 can drive the wire lever 5 to rotate through the extension shaft 16. Since the wire lever 5 and the lead screw sleeve 4 threads cooperate with each other, the rotating wire lever 5 can push the lead screw sleeve 4 to move up and down, and this group of lead screw sleeves 4 drives a group of convex sliders 3 on the left to move synchronously, and a group of convex sliders 3 on the left drive the pull rod 7 and a group of convex sliders 3 on the right to move synchronously. The pull rod 7 moving up and down can clear the stuck goods. During this process, external dust or impurities cannot enter the interior of the vending machine housing 1, and the right-angle plate 11 plays a role The function of installing the connecting shaft 12 is to install the cover 9 to prevent foreign objects from contacting the first bevel gear 17 and the second bevel gear 18. The vertical rod 6 ensures the stability of the up and down movement of a group of convex sliders 3 on the right side. Through the built-in convex slide 2 and the convex slider 3, it is possible to prevent external dust or impurities from entering the vending machine without affecting the clearing work, thereby improving the practicality of the auxiliary pull rod device of the vending machine. At the same time, according to the above operation, it can be known that the pull rod 7 moving up and down can clear the stuck goods, and the goods will eventually fall on the upper part of the lifting plate 8. The lifting plate 8 will squeeze the two groups of telescopic springs 21 through the two groups of connecting rods 23 and the moving plate 22. When the moving plate 22 presses the push switch 25, the buzzer alarm 24 starts to work. Consumers can know through the buzzer alarm 24 whether the blocked goods have been cleared. The two groups of filters 26 can ensure that the sound emitted by the buzzer alarm 24 can be transmitted to the inside of the covering cover 19. Through the provided lifting plate 8, it can help consumers know whether the blocked goods have been cleared, thereby adding a prompt alarm function to the auxiliary pull rod device of the vending machine.
