Description

Technical Field

[0001] The utility model relates to the technical field of automatic vending machines, in particular to a limiting mechanism of a pickup basket and an automatic vending machine. Background Art

[0002] Vending machines are commonly used equipment in commercial automation. They are not restricted by time and place, can save manpower and facilitate transactions. They are a new form of commercial retail, also known as 24-hour mini supermarkets.

[0003] Existing vending machines include those that use a drop-type dispensing mechanism, as well as those that utilize a hopper, basket, or lifting platform to receive and dispense goods. Existing vending machines include the Chinese utility model patent application number CN201920556249.9, titled "A hopper and vending machine with anti-theft function," and the Chinese utility model patent application number CN201921337333.8, titled "A lifting platform." Both use a hopper to dispense goods, and a shielding mechanism, such as a roller shutter or mesh belt, is installed on the basket's track. When the basket moves to the aisle to retrieve goods, the shielding mechanism rotates within the track to the outlet, shielding the outlet. After the basket has retrieved the goods, it moves to the vending machine's outlet, shielding the inlet and providing a theft-proof function. Both of the above patents set the shielding mechanism in the track of the picking basket for sliding, thereby improving the space utilization of the picking basket and reducing the volume of the limiting mechanism of the picking basket.

[0004] The existing picking basket uses a micro switch to limit the movement of the shielding mechanism, that is, two micro switches are respectively set at the extreme ends of the movement of the shielding mechanism, and the sensing end of the micro switch is set on the track. When the shielding mechanism touches the sensing end of the micro switch, it stops moving. Since the shielding mechanism moves back and forth between the picking port and the feeding port, it will often rub the sensing end of the micro switch. Over time, the sensing end of the micro switch will wear out, shortening the service life of the micro switch.

[0005] In view of this, it is necessary to propose a new technical solution to solve the above technical problems. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a limiting mechanism for a pickup basket and an automatic vending machine to solve the problems raised in the background technology.

[0007] To achieve the above object, in a first aspect, the present utility model provides a limiting mechanism for a picking basket, including a microswitch installed on the picking basket body, including a limiting member. The limiting member is slidably or rotatably installed on the body. The first end of the limiting member extends into the track of the body, and the second end of the limiting member is located on one side of the sensing end of the microswitch; when the shielding mechanism presses the first end of the limiting member in the track, the second end of the limiting member moves away from the sensing end of the microswitch.

[0008] In a further technical solution, it further includes a mounting seat and an elastic member. The mounting seat is installed on the body. The first end of the elastic member abuts against the mounting seat, and the second end of the elastic member abuts against the first end of the limiting member, for pushing the limiting member into the track of the body. When the shielding mechanism presses the first end of the limiting member in the track, the elastic member contracts.

[0009] In a further technical solution, the limiting member is provided with a mounting cavity for accommodating the elastic member, and the second end of the elastic member abuts against the bottom of the mounting cavity.

[0010] In a further technical solution, a fixing member is arranged in the mounting cavity. The fixing member is in the shape of a hollow cylinder, and the second end of the elastic member is installed in the fixing member.

[0011] In a further technical solution, the elastic member is selected as a spring.

[0012] In a further technical solution, the mounting seat protrudes upward to form a slider, and a chute is recessed inward on one side of the limiting member. The limiting member is slidably installed on the slider through the chute.

[0013] In a further technical solution, the top of the limiting member is trapezoidal.

[0014] In a further technical solution, the limiting member is provided with a mounting hole, and a rotating shaft is installed in the mounting hole. The rotating shaft is installed on the body, and the limiting member rotates on the body through the rotating shaft.

[0015] In a further technical solution, the second end of the limiting member is provided with a reinforcing rib.

[0016] In a second aspect, the present utility model further provides a vending machine, including a limiting mechanism for a picking basket.

[0017] Compared with the prior art, the present utility model brings the following technical effects:

[0018] The limit mechanism of the goods pickup basket of the present utility model touches the sensing end of the microswitch through the setting of the limiting member, avoiding repeated friction of the sensing end of the microswitch by the shielding mechanism, reducing the wear of the microswitch, prolonging the service life of the microswitch, with a simple structure and strong practicability.

[0019] The vending machine of the present utility model includes all the technical features and technical effects of the limit mechanism of the goods pickup basket, so it will not be elaborated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Embodiment 1

[0038] See Figures 1-5 As shown, the limiting mechanism of the pick-up basket includes a microswitch 2 installed on the pick-up basket body 1, including a limiting member 3. The limiting member 3 is slidably or rotatably installed on the body. The first end of the limiting member 3 extends into the track of the body, and the second end of the limiting member 3 is located on one side of the sensing end of the microswitch 2. When the shielding mechanism presses the first end of the limiting member 3 in the track, the second end of the limiting member 3 moves away from the sensing end of the microswitch 2.

[0039] By arranging the limiting member 3 to touch the sensing end of the microswitch 2, it is avoided that the shielding mechanism repeatedly rubs the sensing end of the microswitch 2, reducing the wear of the microswitch 2 and prolonging the service life of the microswitch 2. The structure is simple and the practicability is strong. It should be noted that the contact end of the limiting member 3 and the limit switch of this embodiment are far away from each other when in the limiting state.

[0040] In a further specific embodiment, it further includes a mounting seat 4 and an elastic member 5. The mounting seat 4 is installed on the body. The first end of the elastic member 5 abuts against the mounting seat 4, and the second end of the elastic member 5 abuts against the first end of the limiting member 3, for pushing the limiting member 3 into the track of the body. When the shielding mechanism presses the first end of the limiting member 3 in the track, the elastic member 5 contracts. As a preferred embodiment, the elastic member 5 of this embodiment is selected as a spring.

[0041] By arranging the elastic member 5 and the mounting seat 4, the limiting member 3 is always subjected to an upward force. It can be understood that when the elastic member 5 extends and pushes the first end of the limiting member 3 into the track, the second end of the limiting member 3 touches the sensing end of the microswitch 2. When the shielding mechanism presses the first end of the limiting member 3 in the track, the elastic member 5 is stressed and contracts, and the second end of the limiting member 3 moves away from the sensing end of the microswitch 2.

[0042] In a further specific embodiment, the limiting member 3 is provided with a mounting cavity 31 for accommodating the elastic member 5, and the second end of the elastic member 5 abuts against the bottom of the mounting cavity 31. Through the arrangement of the mounting cavity 31, the second end of the elastic member 5 is limited, avoiding the deviation of the elastic member 5 during the contraction and extension process.

[0043] In a further specific embodiment, a fixing member 311 is arranged in the mounting cavity 31. The fixing member 311 is in the shape of a hollow cylinder, and the second end of the elastic member 5 is installed in the fixing member 311.

[0044] Through the arrangement of the fixing member 311, the second end of the elastic member 5 can be better limited, so that the elastic member 5 is always located in the fixing member 311, further strengthening the stability of the elastic member 5 and avoiding deviation.

[0045] In a further specific embodiment, a slider 41 protrudes upward from the mounting base 4, and a chute 32 is recessed inwardly on one side of the limiting member 3. The limiting member 3 is slidably mounted on the slider 41 through the chute 32.

[0046] Through the arrangement of the chute 32 and the slider 41, the movement of the limiting member 3 is guided to prevent the limiting member 3 from shifting when pushed by the shielding mechanism.

[0047] In a further specific embodiment, the top of the limiting member 3 is trapezoidal in shape. The trapezoidal limiting member 3 enables the shielding mechanism to receive a buffering and transitional force when contacting the limiting member 3, reducing the impact received.

[0048] In a further specific embodiment, a reinforcing rib 33 is provided at the second end of the limiting member 3. The strength of the second end of the limiting member 3 is strengthened by the reinforcing rib 33, delaying the service life.

[0049] Embodiment 2

[0050] The difference between this embodiment and Embodiment 1 is only that: "a mounting hole is formed in the limiting member 3, a rotating shaft is installed in the mounting hole, the rotating shaft is installed on the body, and the limiting member 3 rotates on the body through the rotating shaft." Others are not elaborated. Through the arrangement of the rotating shaft, the first end and the second end of the limiting member 3 can rotate around the rotating shaft. Therefore, when the shielding mechanism touches the first end of the limiting member 3 and presses down the limiting member 3, the second end of the limiting member 3 moves upward to touch the microswitch 2, thereby completing the limiting. It should be noted that in this embodiment, the sensing end of the limiting member 3 and the microswitch 2 are in contact state during limiting.

[0051] Embodiment 3
