This device includes an isolation frame, with an isolation mesh fixedly connected to one side of the frame. A locking plate is fixedly connected to the inner bottom wall of the isolation mesh. The locking plate has a locking hole on its front, and a locking rod is movably connected to the inner wall of the locking hole. An isolation mesh frame is fixedly connected to the front of the locking rod, and an isolation mesh body is fixedly connected to the inner wall of the isolation mesh frame. This chemical safety isolation device, through its isolation frame, isolation mesh frame, isolation mesh body, isolation mesh, mounting plate, locking rod, limiting pad, locking hole, and locking plate, allows for direct replacement of damaged isolation mesh during the isolation of chemical production equipment, eliminating the need to replace the entire isolation device. This reduces operating costs and further facilitates use.

[0004] While the aforementioned technologies allow for direct replacement of damaged isolation nets without replacing the entire isolation equipment, the fixed height of the isolation frame limits its flexibility and adaptability. Therefore, a chemical safety isolation device is proposed to address these issues. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3This utility model provides an embodiment of a chemical safety isolation device, including an isolation frame 1, which serves as the main frame of the entire isolation device, supporting and fixing other components. It also works with a fixing frame 2 to install and fix an isolation net 3. Two bolt-mounted fixing blocks are provided on both sides. A fixing frame 2 is located on the front of the isolation frame 1 to fix and limit the isolation net 3, facilitating replacement when the net 3 is damaged. A rubber pad is provided on the rear of the fixing frame 2 for cushioning and sealing, enhancing the connection stability between the fixing frame 2 and the isolation frame 1. An isolation net 3 is located inside the isolation frame 1 to isolate the chemical area and prevent personnel or objects from accidentally entering the hazardous area. An adjustment component is provided on the inner wall of the isolation frame 1, including an adjustment column 41. The adjustment column 41 is fixed by a slot 42 cooperating with a limiting block 43, thereby adjusting the height of the isolation device.

[0033] Furthermore, the adjusting column 41 is slidably connected to the lower inner wall of the isolation frame 1. A slot 42 is provided on the left side of the adjusting column 41 for insertion with the limiting block 43 to fix the position of the adjusting column 41. A base plate 6 is fixedly connected to the bottom end of the adjusting column 41 for stable support of the entire isolation device. When the height of the isolation frame 1 needs to be adjusted, the operator can step on the base plate 6 to limit the adjusting column 41, thereby facilitating height adjustment. A protrusion is provided on the left side of the base plate 6, and a groove is provided on the right side of the base plate 6. When the two sets of devices are installed, the protrusion and groove on the base plate 6 are engaged to improve the stability of the two sets of devices when combined. A limiting block 43 is slidably connected to the lower inner wall of the isolation frame 1. By inserting into the inner wall of the slot 42, the adjusting column 41 is limited. The limiting block 43 is inserted into the inner wall of the slot 42.

[0034] Reference Figure 2 - Figure 4 The left side of the limiting block 43 is elastically connected to the isolation frame 1 through a compression spring 44, which provides elastic force to the limiting block 43 so that it is inserted into the slot 42. The upper side of the limiting block 43 near the adjusting column 41 is set as an inclined surface. When the isolation frame 1 is pulled upward to adjust the height, the inclined surface of the limiting block 43 is pressed against the outside of the adjusting column 41, which compresses the compression spring 44. Then, the elastic force of the compression spring 44 makes the limiting block 43 quickly reinsert into the slot 42, which can limit and fix the isolation frame 1 at any time. A pull rod 45 is slidably connected to the lower inner wall of the limiting block 43 for the convenience of the operator to pull the limiting block 43. The pull rod 45 is slidably connected to the inner wall of the isolation frame 1.

[0035] Furthermore, a limiting groove 46 is provided at the lower part of the isolation frame 1. After the pull rod 45 is pulled, the limiting groove 46 can limit the pull rod 45 and the limiting block 43, thereby facilitating the downward adjustment of the height of the isolation frame 1. A plug 47 is fixedly connected to the right side of the limiting groove 46, and a slot 48 is provided on the right side of the pull rod 45. The slot 48 cooperates with the plug 47 to improve the stability when limiting the pull rod 45. Two sets of adjustment components are provided, and the two sets of adjustment components are symmetrically arranged with the center line of the isolation frame 1 as the axis of symmetry, which can improve the stability during adjustment.

[0036] Reference Figure 1 , Figure 2 and Figure 5 A limiting assembly is provided on the inner left side of the fixed frame 2. The limiting assembly includes a limiting rod 51, which is slidably connected to the inner wall of the fixed frame 2. The limiting rod 51 is inserted into the inner wall of the isolation frame 1 to quickly fix the fixed frame 2. A pull handle 53 is fixedly connected to the right side of the limiting rod 51 to facilitate pulling the limiting rod 51 to release the connection between the fixed frame 2 and the isolation frame 1. At the same time, the fixed frame 2 can be pulled after being released from fixation by the pull handle 53.

[0037] Furthermore, the left side of the limiting rod 51 is inserted into the inner wall of the isolation frame 1, and a baffle is fixedly connected to the outside of the limiting rod 51 to cooperate with the return spring 52 to limit the movement range of the limiting rod 51. The right side of the baffle is elastically connected to the fixed frame 2 through the return spring 52 to provide elastic force to the limiting rod 51 so that it remains inserted in the isolation frame 1.

[0038] Working principle: When the height of the isolation device needs to be adjusted, the operator can step on the base plate 6 and pull the isolation frame 1 upward. The adjusting column 41 slides on the lower inner wall of the isolation frame 1. The limiting block 43 presses against the outside of the adjusting column 41 near the inclined surface of the upper side of the adjusting column 41, which in turn compresses the compression spring 44. When the adjusting column 41 moves to the appropriate position, the elastic force of the compression spring 44 causes the limiting block 43 to quickly re-insert into the slot 42, thereby limiting and fixing the isolation frame 1.

[0039] To adjust the height of the isolation frame 1 downwards, pull the lever 45 to disengage the limiting block 43 from the slot 42, releasing the limiting effect on the adjusting post 41. At the same time, slide the lever 45 into the limiting groove 46 so that the slot 48 on the right side of the lever 45 engages with the insert post 47 on the right side of the limiting groove 46, thus limiting the limiting block 43. At this time, the height of the isolation frame 1 can be adjusted downwards.

[0040] When the isolation net 3 is damaged and needs to be replaced, pull the handle 53 to move the limit rod 51 outward, so that the limit rod 51 slides out from the inner wall of the isolation frame 1 and compresses the reset spring 52, releasing the connection between the fixed frame 2 and the isolation frame 1. At this time, the fixed frame 2 can be opened to maintain or replace the damaged isolation net 3.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
