Description

Technical Field

[0001] This utility model relates to the field of chemical safety protection technology, and in particular to a chemical safety protection device. Background Technology

[0002] Chemical engineering encompasses chemical processes, chemical industry, and chemical engineering. It refers to the technology of using chemical methods to change the composition and structure of substances or to synthesize new substances. All of these belong to chemical production technology, also known as chemical processes. The resulting products are called chemicals or chemical products. In order to avoid accidents during the chemical production process, protective devices are usually installed on chemical production equipment.

[0003] An existing chemical safety protection device (publication number: CN220205074U) has at least the following drawbacks: During installation, the device achieves rapid disassembly and maintenance through the coordinated use of structures such as switches, upper top plates, adapter columns, pipes, lower top plates, grooves, buckles, slots, blocks, telescopic rods, and second springs. However, after the second spring fixes and limits the buckle, both the block and the buckle are located in the slot, making it inconvenient for workers to pull the block out of the buckle for disassembly and maintenance. Furthermore, the pipe is located in the groove of the lower top plate, and there is no fixation between the lower top plate and the pipe. After opening the upper and lower top plates, the device is prone to fall directly from the pipe, resulting in poor installation and consequently, inadequate protection. Therefore, we propose this utility model. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a chemical safety protection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A chemical safety protection device includes a lower guard plate, an upper guard plate being rotatably mounted on the top surface of the lower guard plate via a hinge, an installation structure being provided inside the lower guard plate, the installation structure including two winding rollers rotatably mounted on the top surface of the lower guard plate, a fixing belt being fixed to the outer circular wall surface of each of the two winding rollers, a connecting block being fixed to one end of the fixing belt, the connecting block being slidably mounted to the top surface of the lower guard plate, and a connecting rod being fixed between the two winding rollers.

[0007] As a further embodiment of this utility model, an installation strip is fixed to the outer circular wall of the lower guard plate, and a fixing strip is fixed to the outer circular wall of the upper guard plate. Two snap-fit ​​blocks are fixed to the bottom surface of the fixing strip, and two snap-fit ​​grooves are opened on the top surface of the installation strip. The snap-fit ​​blocks are slidably inserted into the snap-fit ​​grooves. An installation groove is opened inside the installation strip, and the installation groove communicates with the two snap-fit ​​grooves. Two racks are slidably arranged inside the installation groove. The two racks are arranged vertically, and a gear meshes between the two racks. The two racks are slidably inserted into the two snap-fit ​​blocks respectively. A throttle is fixed to one side of the installation strip, and the throttle is fixed to one side of the gear.

[0008] As a further embodiment of this utility model, a limiting plate is fixed to the outer circular wall of the connecting rod, and a plurality of toothed grooves are provided on the outer circular wall of the limiting plate. A limiting block is slidably provided on one side of the inner wall of the lower guard plate, and the limiting block is slidably inserted into the toothed groove.

[0009] As a further embodiment of this utility model, the interior of both the lower guard plate and the upper guard plate is provided with a number of arc plates. A first buffer block is fixed between the lower arc plates and the inner wall of the lower guard plate, and a second buffer block is fixed between the upper arc plates and the inner wall of the upper guard plate.

[0010] As a further embodiment of this utility model, the bottom surface of the upper guard plate has two stabilizing grooves, and two fixing straps are slidably inserted into the interior of the two stabilizing grooves respectively.

[0011] As a further embodiment of this utility model, the sides of the upper and lower arc plates that are close to each other are both arc surfaces, and the curvature of the arc surface of the arc plate is consistent with the curvature of the groove on the top surface of the lower guard plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This chemical safety protection device, through its installation structure, allows workers to place the pipeline in the groove on the top surface of the lower protective plate. The pipeline is then secured by connecting blocks and fixing straps. Rotating the connecting rod causes the winding roller to rewind the fixing straps, tightening the straps to secure the pipeline to the lower protective plate and prevent it from falling out after the device is opened. Afterwards, the upper protective plate is closed, allowing the locking blocks on the bottom of the fixing strips to insert into the locking slots. Rotating the handle causes the gears to turn, moving two racks in opposite directions. The two racks then insert into the two locking blocks, securing them in place. For disassembly, simply rotating the gears in the opposite direction opens both the upper and lower protective plates, facilitating quick assembly and disassembly and improving both installation and protective effectiveness.

[0024] like Figures 1-6 As shown, a chemical safety protection device includes a lower guard plate 1. An upper guard plate 2 is rotatably mounted on the top surface of the lower guard plate 1 via a hinge. An installation structure is provided inside the lower guard plate 1. The installation structure includes two winding rollers 201 rotatably mounted on the top surface of the lower guard plate 1. A fixing band 202 is fixed to the outer circular wall surface of each of the two winding rollers 201. A connecting block 203 is fixed to one end of the fixing band 202. The connecting block 203 is slidably mounted to the top surface of the lower guard plate 1. A connecting rod 204 is fixed between the two winding rollers 201. The fixing band 202 is made of nylon.

[0025] In this embodiment, an installation strip 3 is fixed to the outer circular wall of the lower guard plate 1, and a fixing strip 301 is fixed to the outer circular wall of the upper guard plate 2. Two snap-fit ​​blocks 302 are fixed to the bottom surface of the fixing strip 301, and two snap-fit ​​grooves 303 are formed on the top surface of the installation strip 3. The snap-fit ​​blocks 302 are slidably inserted into the snap-fit ​​grooves 303. An installation groove 304 is formed inside the installation strip 3, which communicates with the two snap-fit ​​grooves 303. Two racks 305 are slidably arranged inside the installation groove 304. The two racks 305 are arranged vertically, and a gear 306 meshes between the two racks 305. The two racks 305 are slidably inserted into the two snap-fit ​​blocks 302 respectively. A handle is fixed to one side of the installation strip 3, and the handle is fixed to one side of the gear 306. With the installation structure, the operator places the pipe on the lower guard plate. The pipe is then wrapped and fixed by connecting block 203 and fixing strap 202 in the groove on the top surface of plate 1. The connecting rod 204 is rotated to make the winding roller 201 wind up the fixing strap 202, so that the fixing strap 202 tightens the pipe and fixes the pipe to the lower guard plate 1 to prevent it from falling off after the device is opened. Then the upper guard plate 2 is closed, so that the snap-fit ​​block 302 on the bottom surface of the fixing strip 301 is inserted into the snap-fit ​​groove 303. The handle is turned to make the gear 306 rotate. The rotation of the gear 306 causes the two racks 305 to move in opposite directions. The two racks 305 are respectively inserted into the two snap-fit ​​blocks 302 to fix the snap-fit ​​blocks 302. When disassembling, simply rotate the gear 306 in the opposite direction to open the upper guard plate 2 and the lower guard plate 1, so as to facilitate the quick disassembly and assembly of the device by the staff and improve the installation effect and protection effect of the device.

[0026] In this embodiment, a limiting plate 4 is fixed on the outer circular wall of the connecting rod 204. The outer circular wall of the limiting plate 4 is provided with a plurality of toothed grooves 402. A limiting block 401 is slidably provided on one side of the inner wall of the lower guard plate 1. The limiting block 401 and the toothed grooves 402 are slidably inserted. After the operator rotates the connecting rod 204, the limiting block 401 can be inserted into the toothed grooves 402 to limit the connecting rod 204 and prevent the fixing belt 202 from loosening.

[0027] In this embodiment, both the lower guard plate 1 and the upper guard plate 2 are provided with a plurality of arc plates 5 inside. A first buffer block 501 is fixed between the lower arc plates 5 and the inner wall of the lower guard plate 1, and a second buffer block 502 is fixed between the upper arc plates 5 and the inner wall of the upper guard plate 2. Both the first buffer block 501 and the second buffer block 502 are made of rubber. When the pipeline is vibrated, the first buffer block 501 and the second buffer block 502 buffer and reduce the vibration, prevent the pipeline from being damaged, and improve the protective effect of the device.

[0028] In this embodiment, two stabilizing grooves 6 are provided on the bottom surface of the upper guard plate 2, and two fixing straps 202 are slidably inserted into the interior of the two stabilizing grooves 6 respectively. When the upper guard plate 2 and the lower guard plate 1 are closed, the fixing straps 202 enter the stabilizing grooves 6, thereby preventing the fixing straps 202 from colliding and interfering with the upper guard plate 2.

[0029] In this embodiment, the sides of the upper and lower arc plates 5 that are close to each other are arc surfaces. The arc curvature of the arc plate 5 is consistent with the arc curvature of the groove on the top surface of the lower guard plate 1. The arc surface of the arc plate 5 can wrap and protect the outer circular wall of the pipe, thereby enhancing the protective effect.

[0030] Working principle: In use, through the installation structure, the operator places the pipe in the groove on the top surface of the lower guard plate 1. Then, the pipe is wrapped and fixed by the connecting block 203 and the fixing strap 202. Rotating the connecting rod 204 causes the winding roller 201 to wind up the fixing strap 202, tightening the fixing strap 202 to fix the pipe to the lower guard plate 1, preventing it from falling off after the device is opened. After that, the guard plate 2 is closed, so that the snap-fit ​​block 302 on the bottom surface of the fixing strip 301 is inserted into the snap-fit ​​groove 303. Turning the handle causes the gear 306 to rotate, which causes the two racks 305 to move in opposite directions. The two racks 305 are respectively inserted into the two snap-fit ​​blocks 302 to fix the snap-fit ​​blocks 302. When disassembling, simply reverse the direction. Rotating gear 306 opens the upper guard plate 2 and lower guard plate 1, facilitating quick assembly and disassembly of the device and improving installation and protection. Rotating connecting rod 204 allows the limiting block 401 to be inserted into the toothed groove 402, thus limiting the connecting rod 204 and preventing the fixing strap 202 from loosening. When the pipeline is subjected to vibration, the first buffer block 501 and the second buffer block 502 buffer and reduce the vibration, preventing damage to the pipeline and improving the device's protective effect. When the upper guard plate 2 and lower guard plate 1 are closed, the fixing strap 202 enters the stabilizing groove 6, preventing contact or interference between the fixing strap 202 and the upper guard plate 2. The arc surface of the arc plate 5 can wrap and protect the outer wall of the pipeline, enhancing the protective effect.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
