Description

Technical Field

[0001] The utility model relates to the technical field of chemical safety, in particular to a protective device for chemical safety. Background Art

[0002] Chemical engineering is an abbreviation for "chemical process," "chemical industry," and "chemical engineering." Any technology that uses chemical methods to change the composition or structure of a substance or synthesize new substances is considered a chemical production technology, or chemical process. The resulting products are called chemicals or chemical products. Chemical engineering is the science that studies the common laws governing the production of chemical products. Humanity and the chemical industry have a close relationship. Some chemical products have played a landmark role in human development, and their production and application even represent a specific historical stage of human civilization. However, due to the numerous unsafe factors in each link of chemical production and their mutual influence, accidents can be extremely dangerous and harmful, with serious consequences. Protective devices are often required at chemical production sites to seal off the site and restrict the entry and exit of personnel, materials, machinery, and vehicles.

[0003] Technicians engaged in this industry have found that most chemical safety protection devices are fixed structures. When they need to be moved to other sites for use, they are difficult to disassemble and cannot be disassembled and assembled in a timely and quick manner. A large amount of space is wasted during disassembly and transportation. Therefore, in more urgent situations, it is easy to affect the safety and work efficiency of the staff. For this reason, we propose a chemical safety protection device. Utility Model Content

[0004] The purpose of the present invention is to solve the problem that most chemical safety protection devices are fixed structures, which are difficult to disassemble when they need to be moved to other places for use, cannot be disassembled and assembled in time and quickly, and a large amount of space is wasted during disassembly and transportation. Therefore, in more urgent situations, the safety and work efficiency of the staff are easily affected. The present invention provides a chemical safety protection device.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] The top end face of described sliding panel also is provided with an end face, and the bottom end face of described sliding panel also is provided with an end face.

[0007] Furthermore, a connecting seat is installed on the top of the support column, and a warning light is installed on the upper surface of the connecting seat.

[0008] Furthermore, reinforcing plates are installed on the front and rear sides of the upper surface of the base, and the side walls of the reinforcing plates are connected to the side walls of the support columns.

[0009] Furthermore, the length of the fixing block is greater than the length of the connecting block.

[0010] Furthermore, the diameter of the limiting groove is consistent with the diameter of the limiting column.

[0011] Furthermore, the outer diameter of the spring is slightly smaller than the diameter of the limiting hole.

[0012] Furthermore, the width of the slider is consistent with the width of the slide groove, and the lower surface of the slider is higher than the upper surface of the protective plate.

[0013] The beneficial effects of the utility model are as follows:

[0014] When the utility model is in use, the support column is first installed on the base, and then the fixing block installed at the bottom end of the protective plate is inserted into the fixing groove opened at the bottom end of the supporting column to support the protective plate, and then the slider is pulled upward to allow the slider to move upward with the limiting column, and at the same time, the connecting block installed at the upper end of the protective plate is inserted into the connecting groove, and then the slider is released to allow the limiting column to reset under the action of the spring and be inserted into the limiting groove, thereby fixing the connecting block and the protective plate. Then, when the protective device needs to be disassembled, the slider is pulled upward to allow the slider to pull the limiting column out of the limiting groove, and then the fixing blocks and connecting blocks installed on both sides of the protective plate are pulled out of the fixing groove and the connecting groove respectively, thereby removing the protective plate from the adjacent support columns, thereby improving the disassembly efficiency of the protective device.

[0015] When the utility model is in use, the reinforcement plates are installed on the front and rear sides of the upper surface of the base, which can increase the stability between the support columns and the base, thereby preventing the support columns and the protective plates installed between the support columns from being blown down due to bad weather, affecting the use of the protective device and causing damage to the protective device.

[0016] When the utility model is in use, the length of the fixing block is made greater than the length of the connecting block. When the protective plate is installed between adjacent supporting columns, the fixing block at the bottom end of the protective plate is first connected with the fixing groove at the bottom end of the supporting column to allow the fixing block to support the protective plate. Then, the limiting column is moved upward by the slider, and the connecting block is inserted into the connecting groove. Then, the slider is released to allow the limiting column to reset under the action of the spring, thereby fixing the connecting block in the connecting groove. BRIEF DESCRIPTION OF THE DRAWINGS
