Description

Technical Field

[0001] This application relates to the field of gas cylinder cabinet technology, and more specifically, to a self-locking PP gas cylinder cabinet that facilitates the loading of gas cylinders. Background Technology

[0002] A gas cylinder cabinet is an industrial safety protection device specifically designed for storing flammable and explosive gas cylinders. It is mainly used in factories, laboratories, and other places where hazardous gases need to be stored. The cabinet body is typically made of high-quality cold-rolled steel plate with a thickness of 1.0-1.2mm, treated with pickling and phosphating, and the surface is coated with epoxy resin electrostatic spraying for corrosion and rust prevention. Some models are equipped with explosion-proof glass windows and side ventilation holes.

[0003] PP gas cylinder cabinets refer to gas cylinder cabinets made of polypropylene all-plastic structure. Due to their excellent corrosion resistance and safety, they are widely used in specific fields. PP material itself has excellent chemical resistance and can withstand a variety of strong corrosive liquids or gases such as concentrated hydrochloric acid, hydrofluoric acid, sulfuric acid, and nitric acid for a long time. It can effectively protect gas cylinders from corrosion and is suitable for storing various corrosive gas cylinders. PP material does not release metal ions, avoiding contamination of high-purity process fluids.

[0004] To prevent gas cylinders from tilting and falling, existing methods typically use chains to secure them, ensuring the stability of the cylinders when the cabinet is moved or subjected to impact. However, securing them usually involves manually tightening the chains, which is time-consuming, labor-intensive, and poses certain safety hazards due to the weight of the gas cylinders.

[0005] Therefore, it is necessary for the inventors to design a new self-locking PP gas cylinder cabinet that facilitates the loading of gas cylinders, in order to overcome the above-mentioned problems. Summary of the Invention

[0026] like Figure 1 , Figure 2 and Figure 6As shown, a self-locking PP gas cylinder cabinet for easy gas cylinder storage includes a cabinet body 1. The cabinet body 1 is made of PP material, which has good corrosion resistance and insulation properties, and is suitable for storing various types of gas cylinders. Inside the cabinet body 1, there is a support component 2 for placing gas cylinders. The support component 2 includes a weight sensor at the bottom and a placement platform on the weight sensor. The detection end of the weight sensor abuts against the bottom of the placement platform to detect changes in the weight of the gas cylinders on the platform. Inside the cabinet body 1, there is also a positioning component for positioning the gas cylinders. The positioning component includes a positioning plate 3 inside the cabinet body 1. The positioning plate 3 is fixedly connected to the inner wall of the cabinet body 1 and located above the placement platform. The positioning plate 3 has at least one positioning groove 31. The positioning groove 31 has a U-shaped structure, and its opening size is slightly larger than the diameter of the gas cylinder, facilitating the insertion of the gas cylinder from the opening and its sliding along the inner wall of the positioning groove 31 into the positioning position. The positioning assembly also includes a strap 32, one end of which is detachably connected to the positioning disk 3. The strap 32 is made of high-strength elastic material. The positioning disk 3 has a slot 38, and a plug 39 is provided in the slot 38. The plug 39 is fixedly connected to one end of the strap 32. The strap 32 is detached and connected to the positioning disk 3 by inserting and removing the plug 39 into the slot 38, which facilitates the replacement and maintenance of the strap 32. The positioning disk 3 is also equipped with a self-locking mechanism for fixing the gas cylinder. When the gas cylinder is placed on the placement platform, the weight sensor detects the weight change and generates a sensing signal. After receiving the signal, the self-locking mechanism is activated and locks the gas cylinder through the strap 32. The cabinet 1 also houses a gas extraction assembly 4, which includes several gas pipes detachably connected to the gas cylinder, a gas diversion frame for gas pipe diversion, and a flow meter and flow control valve mounted on the diversion frame. One end of each gas pipe is connected to the gas cylinder valve via a connector, and the other end is connected to the diversion frame. The diversion frame is connected to external processing equipment via a main pipeline. The flow meter monitors the gas flow rate, and the flow control valve adjusts the gas extraction speed. Additionally, the cabinet 1 houses a gas pressure detection assembly 5 and a buzzer 6. The detection end of the gas pressure detection assembly 5 is located inside the cabinet 1 and is used to detect the gas concentration and pressure within the cabinet 1. When the detected gas pressure or concentration exceeds a preset threshold, the gas pressure detection assembly 5 sends a signal to the buzzer 6, which then sounds an alarm to alert personnel.

[0027] Example 1: like Figure 2As shown, in this embodiment, the self-locking mechanism includes a transmission cavity 33 formed within the positioning disk 3. The transmission cavity 33 is arranged along the length direction of the positioning disk 3. A slide rod 35 is provided inside the transmission cavity 33 and is fixedly arranged along the length direction of the transmission cavity 33. A sliding sleeve 36 is fitted on the slide rod 35, and the sliding sleeve 36 can slide back and forth along the length direction of the slide rod 35. The self-locking mechanism also includes a moving block 34 that reciprocates along the length direction of the transmission cavity 33. The moving block 34 is fixedly connected to the sliding sleeve 36, and the other end of the strap 32 is fixedly connected to the moving block 34. The movement of the moving block 34 is guided by the cooperation of the sliding sleeve 36 and the slide rod 35, ensuring the stable movement of the moving block 34. The transmission assembly 37 in this embodiment includes a bidirectional lead screw 371 rotatably arranged along the length of the transmission cavity 33. Both ends of the bidirectional lead screw 371 are rotatably connected to the inner wall of the transmission cavity 33 via bearings. A nut seat is provided in the moving block 34, threadedly connected to the bidirectional lead screw 371. Two positioning slots 31 are provided on the positioning plate 3, spaced apart along the length of the positioning plate 3. Each positioning slot 31 corresponds to a set of straps 32, a moving block 34, and a sliding sleeve 36. The two moving blocks 34 respectively engage with two threaded sections of the bidirectional lead screw 371 with opposite directions of rotation. A controller is provided inside the cabinet 1, and the weight sensor and the drive motor of the bidirectional lead screw 371 are electrically connected to the controller. When the gas cylinders are placed on the placement platforms corresponding to the two positioning slots 31, the weight sensor detects the weight change and sends a signal to the controller. The controller controls the bidirectional lead screw 371 to rotate. Since the two moving blocks 34 are respectively engaged with the reverse threaded sections of the bidirectional lead screw 371, the rotation of the bidirectional lead screw 371 drives the two moving blocks 34 to move towards each other along the slide bar 35, thereby gradually tightening the straps 32 and locking the two gas cylinders in their respective positioning slots 31. When it is necessary to remove the gas cylinders, the controller controls the bidirectional lead screw 371 to rotate in the opposite direction, driving the two moving blocks 34 to move away from each other, loosening the straps 32, and allowing the gas cylinders to be removed. The advantage of this embodiment is that the bidirectional lead screw 371 can simultaneously drive the movement of the two moving blocks 34, achieving synchronous locking of the two gas cylinders, resulting in high operational efficiency and a compact structure that saves internal space in the cabinet 1.

[0028] Example 2: like Figure 4As shown, the difference between this embodiment and Embodiment 1 lies in the structure of the transmission component 37. In this embodiment, the transmission component 37 includes a one-way lead screw 372 rotatably disposed inside the transmission cavity 33. The one-way lead screw 372 is arranged along the length direction of the transmission cavity 33, and its two ends are rotatably connected to the inner wall of the transmission cavity 33 through bearings. The moving block 34 is provided with a nut seat that is threadedly connected to the one-way lead screw 372. Each positioning slot 31 is independently provided with a set of one-way lead screws 372, moving blocks 34, sliding sleeves 36 and straps 32. Each one-way lead screw 372 is equipped with an independent drive motor. Each drive motor is electrically connected to the controller. The number of positioning slots 31 on the positioning disk 3 can be set to one or more according to actual needs. When a gas cylinder is placed in a positioning slot 31, the weight sensor below the corresponding placement platform sends a signal to the controller. The controller then controls the one-way screw 372 corresponding to that positioning slot 31 to rotate, causing the moving block 34 to move along the slide bar 35 towards the positioning slot 31, tightening the strap 32 to lock the gas cylinder. When the gas cylinder needs to be removed, the controller controls the one-way screw 372 to rotate in the opposite direction, causing the moving block 34 to move in the opposite direction, and loosening the strap 32. The advantage of this embodiment is that the locking and unlocking of each gas cylinder can be operated independently, providing high flexibility and making it suitable for scenarios requiring individual gas cylinder handling.

[0029] Example 3: like Figure 5 As shown, in this embodiment, the transmission component 37 of the self-locking mechanism includes an electric telescopic rod 373 disposed inside the transmission cavity 33. The electric telescopic rod 373 is arranged along the length direction of the transmission cavity 33, with its fixed end fixedly connected to the inner wall of the transmission cavity 33 and its output end fixedly connected to the moving block 34. The moving block 34 is fixedly connected to the sliding sleeve 36, which is sleeved on the sliding rod 35. Each positioning slot 31 is correspondingly provided with a set of electric telescopic rods 373, moving blocks 34, sliding sleeves 36, and straps 32. The electric telescopic rod 373 is electrically connected to the controller. When the gas cylinder is placed in the positioning slot 31, the weight sensor sends a signal to the controller, which controls the electric telescopic rod 373 to extend or shorten (determined according to the installation direction), driving the moving block 34 to move along the sliding rod 35, causing the straps 32 to tighten and lock the gas cylinder. When unlocking, the controller controls the electric telescopic rod 373 to move in the opposite direction, and the straps 32 to loosen. The advantage of this embodiment is that the electric telescopic rod 373 has a fast response speed and high control precision. The tension of the strap 32 can be precisely adjusted by controlling the telescopic amount, so as to avoid excessive tension and damage to the gas cylinder.

[0030] Example 4: like Figure 3As shown, in this embodiment, the self-locking mechanism includes a transmission cavity 33 located within the positioning disk 3 and a rotating roller 7 rotatably disposed within the transmission cavity 33. Both ends of the rotating roller 7 are rotatably connected to the inner wall of the transmission cavity 33 via bearings. The drive motor of the rotating roller 7 is electrically connected to the controller. One end of the strap 32 is fixedly connected to the rotating roller 7, and the other end is connected to a slot 38 on the positioning disk 3 via an insert block 39. The positioning disk 3 has one or more positioning slots 31, each corresponding to a set of rotating rollers 7 and straps 32. When the gas cylinder is placed in the positioning slot 31, the weight sensor sends a signal to the controller, which controls the rotating roller 7 to rotate, wrapping the strap 32 around it, gradually tightening the strap 32 to lock the gas cylinder. To unlock, the controller controls the rotating roller 7 to rotate in the opposite direction, releasing the strap 32. The advantages of this embodiment are its simple structure, low manufacturing and maintenance costs, and the precise control of the tightness of the strap 32 through the number of rotations of the rotating roller 7.

[0031] In the above embodiments, the connection method between the air tube and the gas cylinder of the extraction component 4 and the specific structure of the diversion frame can be set according to actual needs. The air pressure detection component 5 can use gas sensors and pressure sensors from the prior art. Its electrical connection relationship with the buzzer 6 and the control logic are conventional technical means and will not be described in detail here. The fixed connection between the strap 32 and the moving block 34 or the rotating roller 7 can be achieved by welding, bolting, or other methods to ensure that the connection strength meets the usage requirements.

[0032] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
