Description

Technical Field

[0001] This utility model belongs to the field of vending equipment technology, and specifically relates to an anti-tilt fixing base for vending machines. Background Technology

[0002] A vending machine, also known as an automatic vending machine, is a retail device that uses automation technology to display, select, pay for, and dispense goods. Vending machines typically include a currency recognition module, a cooling / heating module, a user operation module, a counterweight module, and a fixed base.

[0003] In the existing technology, vending machines have a relatively high center of gravity due to their height, especially spiral vending machines, where the center of gravity is even higher when goods are placed at the top of the machine, and they are prone to jamming.

[0004] When a product gets stuck, some users will push or shake the vending machine in hopes that the product will fall, instead of contacting customer service first. This causes the vending machine's springs to twist or the gaps in the product channel to change after being shaken, making the product stuck or unable to fall smoothly. This increases the chance of product getting stuck, leading to more frequent shaking by users and a significant increase in the failure rate.

[0005] The tilting caused by shaking will generate additional friction at the mechanical connection, which will accelerate gear wear and shorten service life over time.

[0006] Meanwhile, the internal circuitry of precision devices such as barcode scanners and coin acceptors is prone to loosening due to shaking and tilting, leading to payment failures or incorrect amounts, thus reducing the user experience. Utility Model Content

[0007] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-tilt fixing base for vending machines.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a vending machine anti-tilt fixing base, comprising a vending body, the vending body including a base, the base being disposed at the bottom end of the vending body, a base component fixed to the inner wall of the base, a worm gear rotatably connected to the top of the inner wall of the base component, the worm gear teeth meshing with multiple worm wheels, the worm wheels being rotatably connected to the inner wall of the base component, transmission rods fixed to both sides of the worm wheels, moving rods fixed to both ends of the transmission rods, and a support foot slidably connected to one end of the moving rod; multiple rectangular sliding grooves are formed on the inner wall of the base, and the inner wall of the rectangular sliding grooves is slidably connected to the side of the support foot.

[0009] Preferably, a sealing groove is provided at the rectangular sliding groove of the base, and a sealing plate is slidably connected to the inner wall of the sealing groove; the side of the support leg is fixed to the surface of the sealing plate.

[0010] Preferably, a reinforcing rib is fixed to the bottom of the sealing plate, and one side of the reinforcing rib is fixed to the side of the support leg.

[0011] Preferably, the worm gear is driven by a starter motor, which is located below the base component, and the bottom base below the starter motor is provided with an inspection port.

[0012] Preferably, a frustum is fixed to the bottom end of the support leg, the height of the frustum is not greater than one-fifth of the support leg, and the bottom edge of the sealing groove is set as a chamfered edge.

[0013] Preferably, the inner wall of the base is provided with a linkage groove, the inner wall of the linkage groove intersects with the inner walls of the multiple sealing grooves; a connecting plate is slidably connected to the inner wall of the linkage groove, and the two ends of the connecting plate are respectively fixed to the sides of different support legs.

[0014] Preferably, a protrusion is provided on one side of the front of the vending body, a side protrusion is fixed on one side of the protrusion, and an L-shaped corner protrusion is fixed at the diagonal of the side protrusion of the vending body; heat dissipation holes are provided on one side of the side protrusion and one side of the L-shaped corner protrusion.

[0015] Preferably, rubber pads are glued to the bottom of both the side protrusion and the L-shaped corner protrusion.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model uses a starter motor to drive a worm gear to rotate and engage a worm wheel, allowing the operator to adjust the outriggers to move downwards or upwards. When the operator needs to move the vending machine, moving the outriggers downwards supports the vending machine, increasing the distance between the vending machine and the ground. The operator can then place a pallet jack under the vending machine for easy dragging and moving. When the vending machine is transported to a suitable position, the operator can control the starter motor to reverse the worm gear, raising the outriggers and significantly reducing the distance between the vending machine and the ground. This lowers the center of gravity of the vending machine, and when the vending machine is shaken, a slight change in the angle of the vending machine will cause the base to contact the ground, providing support and effectively preventing the vending machine from swaying and tipping over.

[0018] 2. This utility model uses a sealing plate to allow the vending body to directly contact the sealing plate and the bottom base after it is lowered. The contact between the sealing plate and the bottom base provides support, distributes the stress at the worm gear and worm, and prevents damage to them. At the same time, since there is a lot of food on the inner wall of the vending body, the cooperation between the sealing plate and the sealing groove, as well as the tight fit brought by the support, can prevent rats and insects from entering, thus effectively preventing the food on the inner wall from being damaged.

[0019] 3. This utility model increases the response speed of contact with the ground through the protrusion, side protrusion and L-shaped corner protrusion. When slightly tilted, the protrusion, side protrusion or L-shaped corner protrusion will contact the ground and provide support, further preventing tipping and shaking. At the same time, the rubber pad contacts the ground when the vending machine shakes to provide cushioning, prevent damage, and provide rebound to help the vending machine return to its original position and maintain stability.

[0035] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0036] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0037] Example 1:

[0038] refer to Figures 1-5 A vending machine anti-tilt fixing base includes a vending body 1, which includes a base 101 located at the bottom of the vending body 1. A base component 2 is fixed to the inner wall of the base 101. A worm gear 201 is rotatably connected to the top of the inner wall of the base component 2. Multiple worm wheels 202 are meshed with the tooth grooves of the worm gear 201. The worm wheels 202 are rotatably connected to the inner wall of the base component 2. A transmission rod 203 is fixed to both sides of the worm wheel 202. A moving rod 204 is fixed to both ends of the transmission rod 203. A support foot 205 is slidably connected to one end of the moving rod 204. Multiple rectangular sliding grooves 206 are opened on the inner wall of the base 101. The inner wall of the rectangular sliding grooves 206 is slidably connected to the side of the support foot 205.

[0039] Specifically, by starting the motor 3 to drive the worm gear 201 to rotate and engage the worm wheel 202, the operator can adjust the support leg 205 to move downwards or upwards. When the operator needs to move the vending machine 1, the support leg 205 moves downwards to support the vending machine 1, increasing the distance between the vending machine 1 and the ground. The operator can then place the pallet jack under the vending machine 1 for easy dragging and moving. When the vending machine 1 is transported to a suitable position, the operator can control the starting motor 3 to reverse the worm gear 201, raising the support leg 205 and significantly reducing the distance between the vending machine 1 and the ground. This lowers the center of gravity of the vending machine 1, and when the vending machine 1 is shaken, a slight change in the angle of the vending machine 1 will cause the base 101 to contact the ground and provide support, thus effectively preventing the vending machine 1 from shaking or tipping over.

[0040] A sealing groove 501 is provided at the rectangular sliding groove 206 of the base 101, and a sealing plate 5 is slidably connected to the inner wall of the sealing groove 501; the side of the support leg 205 is fixed to the surface of the sealing plate 5.

[0041] Specifically, the sealing plate 5 allows the vending body 1 to directly contact the bottom base 101 after it is lowered. The contact between the sealing plate 5 and the bottom base 101 provides support force, distributing the stress at the worm gear 202 and worm 201 and preventing damage to them. At the same time, since there is a large amount of food on the inner wall of the vending body 1, the cooperation between the sealing plate 5 and the sealing groove 501, as well as the tight fit brought by the support, can prevent rats and insects from entering, thus effectively preventing damage to the food on the inner wall.

[0042] A reinforcing rib 6 is fixed to the bottom of the sealing plate 5, and one side of the reinforcing rib 6 is fixed to the side of the support leg 205.

[0043] Specifically, when the reinforcing rib 6 makes the sealing plate 5 contact the base 101 to provide support, the reinforcing rib 6 improves the strength of the sealing plate 5 through its own stable triangular structure, so that the sealing plate 5 always maintains stability and prevents deformation of the sealing plate 5, thereby improving the service life of the sealing plate 5.

[0044] The worm gear 201 is driven by the starter motor 3, which is located below the base 2. The bottom base 101 below the starter motor 3 is provided with an inspection port.

[0045] Specifically, by placing the starter motor 3 below the base 2, the starter motor 3 is made closer to the bottom of the base 101. This makes it easier for staff to inspect the starter motor 3 through the inspection port, and also facilitates the heat dissipation arrangement of the starter motor 3, thereby making it easier for staff to operate and improving the user experience.

[0046] A frustum 4 is fixed to the bottom of the support leg 205. The height of the frustum 4 is no more than one-fifth of the support leg 205. The bottom edge of the sealing groove 501 is set as a chamfered edge 401.

[0047] Specifically, the contact area between the support leg 205 and the ground is increased by the frustum component 4. While increasing the contact area, less material is used, reducing production costs. At the same time, the frustum component 4 has a stable triangular cross-section, which reduces the tilt angle when shaking, increases the difficulty of shaking, and improves the service life of the vending body 1.

[0048] The inner wall of the base 101 is provided with a linkage groove 7, and the inner wall of the linkage groove 7 intersects with the inner wall of multiple sealing grooves 501; a connecting plate 701 is slidably connected to the inner wall of the linkage groove 7, and the two ends of the connecting plate 701 are respectively fixed to the side of different support legs 205.

[0049] Specifically, by setting the connecting plate 701, the movement between multiple support legs 205 is kept synchronized. When the operator uses the pallet jack, the connecting plate 701 moves downward away from the linkage groove 7 to block the gap between the support legs 205, thereby preventing the pallet jack from shifting its position when sliding and inserting into the gap between the support legs 205. The blocking effect of the connecting plate 701 makes it easier for the operator to operate the pallet jack.

[0050] A protrusion 8 is provided on one side of the front of the vending body 1. A side protrusion 801 is fixed to one side of the protrusion 8. An L-shaped corner protrusion 802 is fixed at the diagonal of the side protrusion 801 of the vending body 1. Heat dissipation holes are provided on one side of the side protrusion 801 and one side of the L-shaped corner protrusion 802. Rubber pads 9 are glued to the bottom of the side protrusion 801 and the bottom of the L-shaped corner protrusion 802.

[0051] Specifically, the response speed to ground contact is increased by the protrusion 8, side protrusion 801, and L-shaped corner protrusion 802. When slightly tilted, the protrusion 8, side protrusion 801, or L-shaped corner protrusion 802 will contact the ground and provide support, further preventing tipping and shaking. At the same time, the rubber pad 9 contacts the ground when the vending machine body 1 shakes, thereby providing cushioning to prevent damage and providing rebound to help the vending machine body 1 return to its original position and maintain stability. Meanwhile, the heat dissipation vents of the vending machine body 1 are changed from being directly facing the wall or venting outwards to facing the side of the vending machine body 1. The side space is generally open enough and unobstructed. After hot air is exhausted, it can rise and diffuse naturally along the open space on the side, and will not be immediately bounced back to the machine by the wall. Cold air is more easily drawn in from other parts of the machine, which significantly improves the heat dissipation efficiency. This allows the vending machine body 1 to be directly attached to the wall without the need to leave a heat dissipation distance from the wall, further preventing others from shaking or tilting the vending machine body 1.

[0052] Example 2:

[0053] refer to Figures 1-5 Staff members used the structure disclosed in this utility model in a chain supermarket. During nighttime equipment maintenance, technicians operated a smart vending machine (model: VM-4500H) equipped with the structure disclosed in this utility model.

[0054] The vending machine weighs 680kg, and its total weight reaches 1.2 tons after loading 320 bottles of beverages. After the technician pressed the lifting button on the control panel, the SEW R37DT90L4 750W geared motor (rated torque 350N·m) drove four sets of 42CrMo steel worm gears (module 3, transmission ratio 1:40) through a Φ28mm worm gear, causing the four Φ45×5mm seamless steel pipe legs to simultaneously descend 150mm from the base's rectangular sliding groove. As the polyurethane frustum components (bottom surface 120×120mm) at the bottom of the legs contacted the warehouse epoxy floor, the lifting clearance of the machine increased from 30mm to 180mm. At this point, the forks of the Noli CB20 pallet jack (rated load 2 tons) smoothly inserted into the space below the base.

[0055] Once the equipment is moved to the designated location in the A3 aisle of the store, the staff controls the motor to reverse, causing the support legs to retract. The base (Q235 steel plate, 8mm thick) is lowered to a 5mm clearance from the ground, while four 304 stainless steel sealing plates (2mm thick) completely seal the moving groove, forming a 0.5mm gap with the bottom rubber strip for insect prevention. After technicians used a laser level to check that the machine's tilt was ≤0.3°, they initiated a self-test program. Workers simulated a lateral impact. The 80 Shore A hardness nitrile rubber pads (15mm thickness) at the bottom of the front side protrusion (200×150×20mm) and the diagonal L-shaped protrusion (150×150×20mm) of the base first contacted the terrazzo floor, absorbing kinetic energy through an 8mm deformation. Simultaneously, a 2° tilt triggered the grounding of the base's chamfered edge (45° bevel), which, together with the sealing plate supported by reinforcing ribs (50×50×5mm angle steel), formed an auxiliary fulcrum, controlling the sway within ±1.5°. Heat dissipation was achieved through 12 Φ10mm honeycomb holes on the side protrusions and 9 8×40mm slots on the L-shaped parts, maintaining the condenser (Emerson ZF33KA) intake air temperature ≤35℃ even when installed flush against a wall. The entire installation process took 23 minutes, a significant improvement in efficiency compared to traditional bolt-fixing methods.

[0056] The working principle of this utility model is as follows: When the operator starts the motor 3 to drive the worm 201 to rotate, the tooth groove of the worm 201 meshes with the four worm wheels 202 and rotates synchronously. The transmission rods 203 on both sides of the worm wheels 202 drive the moving rod 204 to push the support leg 205 to slide vertically along the rectangular sliding groove 206 of the base 101.

[0057] When the support leg 205 descends, the bottom frustum piece 4 contacts the ground and lifts the main body 1 of the sales unit, so that the pallet jack fork arm can be inserted under the base 101 for movement; after the transport is in place, the motor 3 is started to reverse, the support leg 205 retracts and the base 101 descends, getting closer to the ground. At this time, the sealing plate 5 completely seals the sealing groove 501 to form a rodent and insect barrier, and at the same time the connecting plate 701 slides in the connecting groove 7 to ensure that the movement of the support leg 205 is synchronized.

[0058] When the vending machine is shaken by an external force, the protrusion 8 on the edge of the base 101 and the rubber pad 9 at the bottom of the diagonal L-shaped protrusion 802 will contact the ground first. The rubber pad 9 will absorb the impact force, and the heat dissipation holes of the side protrusion 801 will maintain the heat dissipation efficiency of the equipment. The whole mechanism will trigger the support when the vending machine tilts at a small angle, effectively preventing the product channel from getting stuck and the precision parts from loosening.

[0059] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

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.
