Description

Technical Field

[0001] The present invention relates to the field of intelligent cabinets, and in particular to an unmanned intelligent cabinet and a rapid installation method thereof. Background Art

[0002] Currently, unmanned intelligent cabinets are generally applied in public places such as shopping malls, office buildings, and residential areas to display and sell refrigerated and non-refrigerated goods. In the traditional installation method, after the load cell is installed together with the weighing pan, it is directly fixed to the cabinet body using screw rigidity, which not only has low installation efficiency, high labor intensity, but also is not easy to disassemble. The present invention designs a shelf buckle, an anti-dropping buckle, and a shelf on the aluminum alloy support strips on both sides inside the cabinet, which can ensure zero faults and zero drops of the weighing pan during transportation while ensuring the accuracy of the sensor during use, and can achieve rapid and free assembly. Moreover, when the load cell fails, it increases the convenience of replacement and maintenance.

[0003] In the patent document (CN 210718328 U), a shelf support structure fixed by a buckle is disclosed, which includes a support strip and a shelf support device for supporting the shelf. The shelf support device includes a shelf support member and a locking buckle plate, and the locking buckle plate is used to lock the shelf support member in the card hole of the support strip. The shelf support frame includes a first support section, a second support section, and a third support section connected in sequence. The first support section is vertically perpendicular to the second support section and the bottom end of the first support section is connected to one end of the second support section. In Embodiment 1 thereof, the locking buckle plate is used to limit the displacement of the shelf support member in the vertical direction. In Embodiment 2, the locking buckle plate is connected to the shelf support strip through fastening screws. During transportation, when encountering bumps, there is no blocking object above the shelf, and the shelf is easily jumped out from the first support section, which is likely to cause damage to the cabinet body, and using screws for fixation also increases the complexity of the disassembly work. Summary of the Invention

[0004] In view of the above problems, the present invention provides an unmanned intelligent cabinet and a rapid installation method thereof.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

The shelf includes a shelf, a weighing sensor and a weighing pan, and is detachably and fixedly connected to the shelf fastener. The shelf fastener is detachably and fixedly connected to the support bar. The shelf fastener has a vertically upward connecting section, a fixing section and a supporting section. On each of the extending sections on the upper and lower sides of the fixing section along the vertical direction, there is a shelf fastener fixing part that can be detachably and fixedly connected to the support bar. Four universal wheels are provided at the bottom of the cabinet body. There are several support bars, which are fixedly arranged on the inner side walls of the cabinet body in parallel corresponding to each other. The support bar is provided with several holes as fixing holes. Several layers of shelves are placed inside the cabinet body. The weighing pan is arranged on the shelf, and a weighing sensor is arranged between the weighing pan and the shelf. The weighing sensor is detachably and fixedly connected to the shelf and the weighing pan respectively through a bracket. The bracket has several screw holes. The bottom wall of the shelf has several connecting holes that can be adapted to the connecting section of the shelf fastener. It also includes an anti-dropping buckle, which is detachably and fixedly connected to the support bar. The main body part of the anti-dropping buckle is a frame structure with through holes on the front and rear sides. The cross-section of the through hole is square. On each of the left and right side edges of the anti-dropping buckle, a section extends upward to form an extended edge. Chamfers are provided on the rear sides of the extended edges. A chamfer is also provided on the lower part of the front side of the anti-dropping buckle. The rear side of the top of the anti-dropping buckle has an anti-dropping buckle fixing part adapted to the fixing hole. There is an extended section between the anti-dropping buckle fixing part and the top of the anti-dropping buckle. The lower side of the anti-dropping buckle fixing part has a bent section, and a protrusion is provided on the lower side of the bent section. Chamfers are provided on the front and rear sides of the anti-dropping buckle fixing part, and the length of the front chamfer is greater than the length of the rear chamfer.

[0007] Further, the cross-sections of the fixing hole, the connecting hole and the through hole are all square.

[0008] Further, two vertical support bars are provided on each of the left and right sides of the cabinet body, and a vertical support bar is provided at the middle position of the rear side wall of the cabinet body. The support bars are parallel to each other.

[0009] Further, a total of five layers of shelves are provided, and the weighing sensors are respectively arranged at the central positions on the left and right sides of each layer of shelf.

[0010] Further, the weighing sensor is detachably and fixedly connected to the shelf and the weighing pan respectively by screws through an I-shaped bracket.

[0011] Further, the bent section extends downward from the rear side of the anti-dropping buckle fixing part and bends inward to the anti-dropping buckle, and the protrusion of the bent section is triangular.

[0012] Further, the distance between the shelf fastener and the anti-dropping buckle after they are installed on the support bar is greater than or equal to the height of the shelf and less than the sum of the height of the shelf and the connecting section.

[0013] Further, the length of the extended section and the length from the protrusion of the bent section to the square shell of the anti-dropping buckle are both equal to the thickness of the support bar.

[0014] A rapid installation method for an unmanned intelligent cabinet: The fixing part of the shelf buckle is in an inverted L-shaped structure, and the vertical length of the fixing part of the shelf buckle is less than the length of the fixing hole of the support bar. Both the front and rear sides of the fixing part of the anti-detachment buckle have chamfers, and the length of the front chamfer is greater than that of the rear chamfer. When installing the fixing part of the anti-detachment buckle, it needs to be tilted along the chamfer to avoid getting stuck with the support bar.

[0023] An unmanned intelligent cabinet and its rapid installation method, as Figure 1 shown, includes a cabinet body 1, a support bar 3, a shelf board 2, a shelf buckle 5 and an anti-detachment buckle 4. As Figure 2As shown in the figure, the shelf 2 includes a shelf 201, a weighing sensor, and a weighing pan 203. The bottom of the cabinet 1 is provided with four universal wheels, which can be freely moved according to the needs of users. On the inner walls of the left and right sides of the cabinet 1, two support bars 3 are respectively provided, and on the inner wall at the rear of the cabinet 1, one support bar 3 is provided. Each support bar is vertically corresponding and parallel to each other. The support bar 3 has screw holes and fixing holes 301. The support bar 3 is fixed on the inner side wall of the cabinet 1 through a number of screw holes. In this embodiment, the fixing hole 301 is square. Five layers of shelves 201 are placed in the cabinet 1. Weighing sensors are provided at the central positions on the left and right sides of each layer of the shelf 201. A weighing pan 203 is provided above the weighing sensor. The weighing sensor is detachably and fixedly connected to the shelf 201 and the weighing pan 203 respectively by using screws through an "I"-shaped bracket 202 with upper and lower layers. Square connecting holes are provided around the shelf 201 and at the middle position at the rear side.

[0024] Combined with Figure 3 and Figure 4 As shown in the figure, the main body of the anti-detachment buckle 4 is a frame structure with through holes on the front and rear sides. On each of the left and right edges, a section extends upward to form an extended edge 402. Chamfers with the same length are provided on the rear sides of the two extended edges 402. A chamfer is also provided at the lower part of the front side of the anti-detachment buckle 4. The chamfer has a guiding function to avoid jamming with the fixing hole 301 during installation, facilitating the quick installation or removal of the anti-detachment buckle 4. At the rear side of the top of the anti-detachment buckle 4, there is an anti-detachment buckle fixing part 403 adapted to the fixing hole 301. There is an extended section between the anti-detachment buckle fixing part 403 and the top of the anti-detachment buckle 4. A bent section 404 is provided on the lower side of the anti-detachment buckle fixing part 403. The bent section 404 extends downward from the rear side of the anti-detachment buckle fixing part 403 and bends inward to the anti-detachment buckle 4. A triangular protrusion 405 is provided on the lower side of the bent section 404. The length from the bent section protrusion 405 to the square shell 401 of the anti-detachment buckle is the same as the thickness of the support bar 3.

[0025] As Figure 5 shown in the figure, the shelf buckle 5 includes a connecting section 501 that can be adaptively connected to the connecting hole of the shelf 201, an inverted L-shaped fixing section 502, and a right-angled triangular support section 503. The connecting section 501 is vertically fixed at the front end of the horizontal position of the fixing section 502. The support section 503 is fixed in the fixing section 502 to enhance the strength of the fixing section 502 and prevent the problem of the shelf buckle 5 being bent due to the excessive weight borne by the shelf 2. On the upper and lower sides of the fixing section 502 along the vertical direction, a section extends outward respectively. The rear side of the extended section is connected with a shelf buckle fixing part 504. The shelf buckle fixing part 504 has an inverted L-shaped structure, and the shelf buckle fixing part 504 is correspondingly clamped with the fixing hole 301 of the support bar 3.

[0026] The usage method of the present invention is: Combined with Figure 6 and Figure 7As shown, according to the position of the shelf 201, a thickness of the support bar 3 is reserved by the five-layer shelf buckle 5 using the extension section, and it is snapped onto the support bar 3 through the shelf buckle fixing part 504. The square connection holes on both sides of the shelf 2 are aligned with the connection section 501 of the shelf buckle 5 and inserted. After the installation is completed, an anti-dropping buckle 4 is snapped above the shelf 201. The anti-dropping buckle 4 can tilt the chamfer on the front side into the fixing hole 301 by using the guiding function of the chamfer and avoid getting stuck with the support bar 3. Subsequently, the anti-dropping buckle 4 is pressed back to be upright. The bending section 404 is made of an elastic material and has elastic deformation. The bending section 404 uses the elastic deformation to press and snap the lower protrusion 405 into the inner side of the fixing hole 301 to fix the anti-dropping buckle 4. The bottom of the anti-dropping buckle 4 abuts against the top of the shelf 201 to fix the shelf 2. The distance between the shelf buckle 5 and the anti-dropping buckle 4 after they are installed on the support bar 3 is greater than or equal to the height of the shelf 2 and less than the sum of the height of the shelf 2 and the connection section 501. The shelf buckle 5 and the anti-dropping buckle 4 cooperate with each other to fix the shelf 2. Since the anti-dropping buckle 4 can be stably fixed on the support bar 3, the shelf buckle 5 can also be fixed on the support bar 3 and restricted from shaking up and down. When the cabinet needs to be disassembled, first, the anti-dropping buckle 4 is disassembled. When disassembling, the horizontal free end of the bending section 404 extending into the anti-dropping buckle 4 is pressed upward, so that the bending section protrusion 405 is snapped out of the fixing hole 301, and then the anti-dropping buckle 4 can be removed. Without the restriction of the anti-dropping buckle 4, the shelf 201 can be moved out of the connection section 501 of the shelf buckle 5 to complete the disassembly.

[0027] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the essence of the present invention should also fall within the protection scope of the present invention.
