Description

Technical Field

[0001] This utility model relates to the field of storage cabinets, and in particular to a storage cabinet with an automatic door opening mechanism. Background Technology

[0002] In biological laboratories, storage cabinets are used for storing and classifying materials. To ensure the safety and stability of the materials, the cabinet doors are generally kept closed. When storing or retrieving materials, staff must open the doors. The storage cabinets are divided into sections by partitions, and the contents can be observed through glass windows on the doors.

[0003] With the widespread adoption of laboratory automation, the opening and closing of storage cabinets are now accomplished by robotic arms. However, due to space requirements in automated laboratories, outward-opening cabinets, especially double-opening ones, require sufficient opening space, and the robotic arms also need ample reach, resulting in a relatively large operating space for the storage cabinets.

[0004] Existing automatic door opening mechanisms for cabinets, such as the patent "Gesture-controlled Automatic Top-Opening Wine Cabinet" with application number "202021721621.6", use an electric push rod inside the cabinet. On the one hand, this takes up too much space and is not structurally compact; on the other hand, it is inconvenient to install and disassemble. At the same time, if this door opening mechanism is installed, it will damage the existing storage cabinet or reduce the usable space of the storage cabinet. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a storage cabinet with an automatic door opening mechanism. The door can be opened and closed automatically by the door opening mechanism installed on the top of the cabinet. The door opening mechanism can be installed by sticking a non-residual adhesive, which does not damage the structure and function of the cabinet. At the same time, it is convenient to install and disassemble.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A storage cabinet with an automatic door opening mechanism includes a cabinet body and a cabinet door. The door opening mechanism is installed on the top surface of the cabinet body. The door opening mechanism includes an electric push rod. The push rod of the electric push rod is hinged to the cabinet door through a first mounting component and installed without damage. The tail of the electric push rod is hinged to the cabinet body through a second mounting component and installed without damage.

[0007] The first installation component includes a fixed column base plate, a fixed column is fixed at the center of the upper end of the fixed column base plate, and a push rod is rotatably connected to the fixed column; the fixed column base plate has two transverse elongated holes running through it on the left and right sides; a traceless sticker is pasted on the top of the corresponding cabinet door, and a screw is provided on the traceless sticker, which is engaged with the elongated holes and locked by a nut.

[0008] The second mounting assembly includes an electric push rod base plate, with a fixing post fixed at the center of the upper end of the electric push rod base plate, and an ear plate at the tail end of the electric push rod rotatably connected to the fixing post; four longitudinal elongated holes are provided on the electric push rod base plate; a traceless sticker is pasted on the corresponding cabinet, and a screw is provided on the traceless sticker, which engages with the elongated holes and is locked by a nut.

[0009] There are two sets of traceless stickers on the top of the cabinet door and four sets of traceless stickers on the cabinet body.

[0010] The fixed column includes a column body, and a shaft segment is fixed at the upper end of the column body. The shaft segment includes a lower smooth column segment and an upper threaded segment. The sleeve hole on the ear plate at the tail end of the push rod or electric push rod is freely fitted onto the smooth column segment. The nut is screwed into the threaded segment and limits the push rod or ear plate.

[0011] A photoelectric sensor is installed on the side of the top of the cabinet near the cabinet door, and a positioning plate is installed on the base plate of the fixing column; when the cabinet door is closed, the positioning plate engages with the photoelectric sensor.

[0012] For double-door storage cabinets, each door corresponds to one opening mechanism, and the two opening mechanisms are controlled independently.

[0013] The cabinet door is fitted with a glass window.

[0014] The cabinet is equipped with partitions.

[0015] The storage cabinets are the existing ones that were previously in use.

[0016] This utility model provides a storage cabinet with an automatic door opening mechanism, which has the following technical effects: 1) By installing the door opening mechanism on the top of the cabinet, it does not take up space.

[0017] 2) Install the door opening mechanism using a non-marking adhesive strip without damaging the cabinet structure.

[0018] 3) Position detection via photoelectric sensors ensures that the cabinet door is opened correctly each time. Attached Figure Description

Detailed Implementation

[0028] like Figure 1 As shown, a storage cabinet with an automatic door opening mechanism includes a cabinet body 1 and a cabinet door 2. The cabinet body 1 has internal partitions 3 for classifying and storing various materials and containers. A glass window 4 is provided on the cabinet door 2 for observing the condition of the materials inside the cabinet body 1. The cabinet door 2 can be single-opening or double-opening and is mounted to the side of the cabinet body 1 via hinges (not shown in the figure). The cabinet body 1 and cabinet door 2 are existing cabinets used in the laboratory, ensuring that the existing cabinets are not damaged and reducing costs. At the same time, to improve convenience and automation, a door opening mechanism 9 is installed on the top surface of the cabinet body 1.

[0029] like Figure 2 As shown, the door opening mechanism 9 includes an electric push rod 5. A first mounting component is arranged on the top surface of the cabinet door 2, which enables the push rod 7 of the electric push rod 5 to be hinged to the cabinet door 2. A second mounting component is arranged on the cabinet body 1, which enables the tail of the electric push rod 5 to be hinged to the cabinet body 1.

[0030] like Figure 3-4 As shown, the first installation component includes a fixed column base plate 10, with a fixed column 6 fixed at the center of the upper end of the fixed column base plate 10. The front end of the push rod 7 of the electric push rod 5 is freely fitted onto the fixed column 6 through the sleeve hole 8. Two transverse elongated holes 13 are provided through the left and right ends of the fixed column base plate 10. Two traceless stickers 11 are pasted on the top of the corresponding cabinet door 2. The traceless stickers 11 are provided with screws 12, which are set in the elongated holes 13 and locked by nuts (not shown in the figure).

[0031] The fit between the elongated hole 13 on the base plate 10 of the fixed column and the screw 12 can absorb the error when the traceless sticker 11 is applied. The application and removal of the traceless sticker 11 will not damage the cabinet body 1 itself.

[0032] like Figure 4 As shown, the fixed column 6 includes a column body 14, which is cylindrical. A shaft segment 15 is fixed to the upper end of the column body 14, and the diameter of the shaft segment 15 is smaller than the diameter of the column body 14. The shaft segment 15 includes a lower smooth section and an upper threaded section. The length of the smooth section is greater than the thickness of the push rod 7. After the sleeve hole 8 on the push rod 7 is freely fitted onto the smooth section of the shaft segment 15, the nut is screwed onto the threaded section to limit the movement of the push rod 7. The push rod 7 can rotate relative to the shaft segment 15.

[0033] The second mounting assembly is similar to the first mounting assembly, and includes an electric actuator base plate 16. The upper end of the electric actuator base plate 16 is hinged to the lug plate at the tail end of the electric actuator 5 via a fixing post 6. Four traceless adhesive strips 11 are affixed to the top of the cabinet 1, and each adhesive strip 11 has a screw 12. The electric actuator base plate 16 has four longitudinal elongated holes 13, and the screws 12 are fitted into the elongated holes 13 and locked in place by nuts. Similarly, the elongated holes 13 of the electric actuator base plate 16 are used to absorb installation errors and positional offsets that occur during operation.

[0034] like Figure 6-7 As shown, the door opening mechanism 9 is controlled by a control unit (not shown in the figure). The extension and retraction of the electric push rod 7 by the electric push rod 5 are both controlled by the control unit. When the electric push rod 5 drives the push rod 7 forward, the push rod 7 pushes the fixed column 6 forward while the front end of the push rod 7 rotates around the fixed column 6, causing the cabinet door 2 to rotate and open. When the push rod 7 retracts, the front end of the push rod 7 rotates around the fixed column 6, causing the cabinet door 2 to rotate and close.

[0035] like Figure 4 As shown, a photoelectric sensor 17 (model EE-SX671) is installed on the side of the top of the cabinet 1 near the cabinet door 2, and a positioning piece 18 is installed on the base plate 10 of the fixed column. When the cabinet door 2 is closed, the positioning piece 18 engages with the photoelectric sensor 17, and the control unit confirms that the cabinet door 2 is closed. After receiving the signal from the photoelectric sensor 17, the control unit confirms that the cabinet door 2 is fully closed, and stops the electric push rod 5, completing the closing action. When opening the door, the control unit senses that the cabinet door 2 has been opened based on the signal from the photoelectric sensor 17, and then extends the push rod 7 to a predetermined length to complete the opening action. The control unit here can be a controller, electronic control unit, or control module from the existing technology, all of which are mature technologies, and the control unit is not the subject of this patent.

[0036] For a double-door storage cabinet, each door 2 corresponds to one door opening mechanism 9. The two door opening mechanisms 9 can be controlled independently to meet different door opening and closing needs.
