Abstract
Description
Technical Field
[0001] This utility model relates to the field of storage cabinet technology, and in particular to a chemical safety storage compartment. Background Technology
[0002] Chemicals are frequently used in industry and academic research, including strong acids and bases, corrosives, toxic substances, and oxidants. They are found in large quantities in university laboratories, hospitals, and chemical plants. However, chemicals are generally unstable and prone to volatilization, corrosion, or deliquescence. If not properly protected, they may leak, explode, or burn, posing significant safety hazards and even causing great harm to the human body. Therefore, specialized storage cabinets are needed for the safe storage of chemicals.
[0003] Existing chemical storage cabinets typically secure containers of chemicals inside the cabinet with fastening devices. However, when the cabinet is bumped or vibrated, the chemicals inside may spill out of the containers. Therefore, a chemical safety storage compartment that can mitigate vibration is needed. Utility Model Content
[0004] This utility model addresses the shortcomings of existing technologies by providing a chemical storage compartment that uses brackets A and B to hinge a cabinet for storing chemicals to a box. When the box vibrates due to collision, the cabinet provides a counterforce to the box under the action of inertia, thereby reducing the vibration of the box and cabinet. This makes it a simple, efficient, safe, reliable, and easy-to-operate chemical safety storage compartment.
[0005] This utility model is achieved through the following technical solution: a chemical safety storage compartment is provided, including a box body; a bracket A with a horizontally extending hinge axis is hinged to the box body, and a bracket B with a longitudinally extending hinge axis is hinged to the bracket A; a cabinet for storing chemical containers is fixed to the bottom of the bracket B; the center line of gravity of the cabinet intersects the hinge axes of the bracket A and the bracket B respectively, and the cabinet is located inside the box body; the cabinet for storing chemicals is hinged to the box body by the bracket A and the bracket B; when the box body vibrates due to collision, the cabinet provides a opposite pulling force to the box body under the action of inertia, thereby reducing the vibration of the box body and the cabinet body.
[0006] As an optimization, a counterweight is fixed at the bottom of the cabinet, and the center line of gravity of the counterweight is the same as that of the cabinet; the counterweight lowers the center of gravity of the cabinet, reducing the vibration of the cabinet when it collides with another object.
[0007] As an optimization, the lower end of the cabinet is equipped with a shock-absorbing device and a ball joint. The shock-absorbing device is set on both sides of the cabinet in the longitudinal and transverse directions. The shock-absorbing device absorbs and dissipates the vibration energy between the cabinet and the box, thereby reducing the vibration of the cabinet and the box.
[0008] As an optimization, the cabinet is equipped with several vertically sliding trays that extend horizontally; the vertically sliding trays clamp the chemical containers on the lower trays to prevent them from falling over.
[0009] As an optimization, a flexible anti-slip pad extending horizontally is fixed to the bottom of the tray, and the flexible anti-slip pad is adapted to the internal cross-section of the cabinet; the flexible anti-slip pad is adapted to the top of the chemical containers on the tray below to prevent the containers from falling over.
[0010] As an optimization, permanent magnets are fixed at the bottom of the box and cabinet respectively. The magnetic fields of the two permanent magnets are in the same direction and are located in each other's magnetic fields. The two permanent magnets apply a certain pulling force from the box to the cabinet to prevent the cabinet from shaking, and consume and cancel out the vibration energy when the box and cabinet vibrate.
[0011] The beneficial effects of this utility model are as follows: The cabinet for storing chemicals is hinged to the box body via brackets A and B. When the box body vibrates due to collision, the cabinet body provides a counterforce to the box body under the action of inertia, thereby reducing the vibration of the box body and cabinet body; the counterweight lowers the center of gravity of the cabinet body, reducing the vibration of the cabinet body when the box body collides; the shock absorption device absorbs and dissipates the vibration energy between the box body and cabinet body, reducing the vibration of the box body and cabinet body; the vertically sliding tray clamps the chemical containers on the lower tray, preventing the containers from falling; the flexible anti-slip pad adapts to the top of the chemical containers on the lower tray, preventing the containers from falling; the two permanent magnets apply a certain pulling force from the box body to the cabinet body, preventing the cabinet body from swaying, and consuming and offsetting the vibration energy when the box body and cabinet body vibrate.

[0017] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.
[0018] like Figure 1-3The chemical safety storage compartment of this utility model includes a box body 1; a bracket A2 with a horizontally extending hinge axis is hinged inside the box body 1, and a bracket B3 with a longitudinally extending hinge axis is hinged on the bracket A2. A cabinet 4 for storing chemical containers is fixed to the bottom of the bracket B3. The center line of gravity of the cabinet 4 intersects the hinge axes of the bracket A2 and the bracket B3 respectively, and the cabinet 4 is located inside the box body 1. The box body 1 and the cabinet 4 extend in the vertical direction. The box body 1 is a sealed box, and an opening communicating with the inside and outside of the box body 1 is opened on the side of the box body 1. A sealed door is provided on the opening. The hinge axes of the bracket A2 and the bracket B3 extend in the horizontal direction. The cabinet 4 extends through both sides in the direction of the opening of the box body 1, that is, the opening is located on the side of the box body 1 in the longitudinal direction. The two sides of the cabinet 4 in the longitudinal direction extend through the inside and outside of the cabinet 4 to ensure the balance of the two sides of the cabinet 4 in the longitudinal direction and prevent the cabinet 4 from tilting.
[0019] The chemical container is placed inside cabinet 4. When cabinet 1 is impacted and vibrates, cabinet 4 moves in the opposite direction relative to cabinet 1 under the action of inertia through brackets A2 and B3, and provides opposite pulling force to cabinet 1. The vibration of cabinet 1 and cabinet 4 gradually decreases.
[0020] like Figure 1 The bottom of the cabinet 4 shown is fixed with a counterweight 5, and the center line of the counterweight 5 and the center line of the cabinet 4 are the same.
[0021] The counterweight 5 is fixed to the bottom of the silicon iron, and the center of gravity of the cabinet 4 is lowered. When the cabinet 1 collides, the vibration amplitude of the cabinet 4 is reduced.
[0022] like Figure 1 The lower end of the cabinet 4 is connected to the box 1 by a shock-absorbing device 6 and a ball joint. The shock-absorbing device 6 is respectively arranged on both sides of the cabinet 4 in the longitudinal and transverse directions. The shock-absorbing device 6 is the prior art. The shock-absorbing device 6 includes a spring and a damper sleeved in the spring. The two ends of the shock-absorbing device 6 are respectively hinged to the box 1 and the cabinet 4 by a ball joint.
[0023] When the enclosure 1 is impacted and vibrates, the cabinet 4 and the enclosure 1 move in opposite directions relative to each other. The shock absorption device 6 absorbs and dissipates the vibration energy between the enclosure 1 and the cabinet 4, and the vibration of the enclosure 1 and the cabinet 4 gradually decreases.
[0024] like Figure 1 and 3 The cabinet 4 shown is provided with several trays 7 that slide vertically and extend horizontally; the cabinet 4 is provided with a slide groove that extends vertically, and the trays 7 slide in the slide groove; the trays 7 are provided with a fastening device for fastening the trays 7 to the cabinet 4 to prevent the upper trays 7 from being too heavy and damaging the chemical containers below.
[0025] The chemical containers are placed from bottom to top on the bottom of the cabinet 4 and on the tray 7. The tray 7 slides vertically downward inside the cabinet 4 until the bottom of the tray 7 meets the top of the chemical container below, thus clamping the chemical container.
[0026] like Figure 1 The bottom of the tray 7 shown is fixed with a flexible anti-slip pad 8 extending in the horizontal direction, and the flexible anti-slip pad 8 is compatible with the inner cavity cross section of the cabinet 4.
[0027] The chemical containers are placed from bottom to top on the bottom of the cabinet 4 and on the tray 7. The tray 7 causes the flexible anti-slip pad 8 to slide vertically downwards inside the cabinet 4. The flexible anti-slip pad 8 and the top of the chemical container below come into contact and gradually deform. The flexible anti-slip pad 8 gradually wraps around the top of the chemical container below until the tray 7 completes the clamping of the chemical container below.
[0028] like Figure 1 Permanent magnets 9 are fixed to the bottom of the box 1 and cabinet 4 respectively. The magnetic fields of the two permanent magnets 9 are in the same direction and are located in each other's magnetic fields. The axis of the magnetic field of the two permanent magnets 9 is the same as the center line of gravity of the cabinet 4.
[0029] Two permanent magnets 9 attract each other, and the box 1 applies a certain pulling force to the bottom of the cabinet 4 through the two permanent magnets 9; when a chemical container is placed into the cabinet 4, the cabinet 4 remains stably inside the box 1 under the attraction of the two permanent magnets 9; when the box 1 is hit by a collision and vibrates, the cabinet 4 and the box 1 move in opposite directions relative to each other, and the magnetic fields of the two permanent magnets 9 cut each other and transform and dissipate the vibration energy between the box 1 and the cabinet 4, and the vibration of the box 1 and the cabinet 4 gradually decreases.
[0030] In actual production, the two permanent magnets 9 attract each other, and the cabinet 1 applies a certain pulling force to the bottom of the cabinet 4 through the two permanent magnets 9; chemical containers are placed from bottom to top on the bottom of the cabinet 4 and the tray 7, and the tray 7 drives the flexible anti-slip pad 8 to slide vertically downwards inside the cabinet 4. The flexible anti-slip pad 8 gradually deforms at the point where it contacts the top of the chemical container below, and the flexible anti-slip pad 8 gradually wraps around the top of the chemical container below until the tray 7 completes the clamping of the chemical container below; the cabinet 4 is subjected to the attraction of the two permanent magnets 9. The counterweight 5 is fixed to the bottom of the silicon iron, and the center of gravity of the cabinet 4 is lowered. When the cabinet 1 is hit by a collision and vibrates, the vibration amplitude of the cabinet 4 is reduced. At the same time, the cabinet 4 moves in the opposite direction to the cabinet 1 under the action of inertia through the brackets A2 and B3 and provides the opposite pulling force to the cabinet 1. The shock absorption device 6 absorbs and dissipates the vibration energy between the cabinet 1 and the cabinet 4. The magnetic fields of the two permanent magnets 9 cut each other and transform and dissipate the vibration energy between the cabinet 1 and the cabinet 4. The vibration of the cabinet 1 and the cabinet 4 gradually decreases.
