Description

Technical Field

[0001] This utility model relates to the field of oil refining construction equipment technology, and in particular to a headgear for safe construction of oil refining units. Background Technology

[0002] Oil refining is the process of converting crude oil (petroleum) into various fuels, chemical raw materials and other products through physical and chemical processing. In the safe construction of oil refining units, the use of headgear is crucial, which is of great significance for protecting the lives, health and occupational safety of construction workers.

[0003] Traditional head-mounted devices are usually designed as a single unit, making it impossible to disassemble and replace the protective cover. This makes it difficult for operators to perform thorough cleaning and affects the comfort of construction workers. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a headgear for safe construction in oil refining units, aiming to improve the problem that traditional headgear cannot be disassembled and the protective cover cannot be replaced.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A headgear for safe operation in an oil refining unit includes a protective cover. The upper interior of the protective cover has a slot, and the interior of the protective cover has a buckle assembly. A bracket is fixedly connected to the outer wall of the buckle assembly. A locking strip is provided on the outer wall of the bracket. A first locking slot, a second locking slot, and a third locking slot are provided on the left interior of the locking strip. A soft pad is fixedly connected to the outer wall of the bracket.

[0006] Preferably, the buckle assembly includes a buckle plate, the outer wall of which is disposed on the inner wall of the buckle groove, an inner groove is formed inside the buckle plate, a spring is disposed on the inner wall of the inner groove, a buckle post is fixedly connected to the left outer wall of the spring, and a push block is fixedly connected to the outer wall of the buckle post.

[0007] Preferably, the card plate has a groove on its left outer wall, and the outer wall of the push block is slidably connected to the inner wall of the groove.

[0008] Preferably, the protective cover consists of an impact layer and a filter layer.

[0009] Preferably, the impact layer is made of polycarbonate.

[0010] Preferably, the filter layer is made of nano-sized activated carbon.

[0011] Preferably, the outer wall of the bracket is disposed on the inner wall of the first bayonet.

[0012] Preferably, the outer wall of the retaining post is slidably connected to the inner wall of the inner groove.

[0013] This utility model has the following beneficial effects: 1. In this utility model, pushing the push block causes the locking column to slide, and then the locking column causes the spring to retract. By pulling out the bracket, the locking plate is driven to leave the slot, so that the protective cover is separated from the bracket. The size of the bracket and the locking strip can be adjusted arbitrarily by using the first locking slot, the second locking slot, and the third locking slot. The soft pad is used to clamp on both sides of the construction personnel, so as to achieve quick disassembly and replacement of the protective cover, making it convenient for construction personnel to clean the protective cover and improving the comfort of construction personnel.

[0014] 2. In this utility model, the impact layer prevents corrosion from contacted chemical substances, and the filter layer effectively adsorbs various harmful gases and fine particles, thereby avoiding the accidental splashing of raw materials onto the face and ensuring the safety of construction personnel.

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Reference Figures 1-3 An embodiment of this utility model provides a headgear for safe construction of an oil refining unit, including a protective cover 1. The upper side of the protective cover 1 has a slot 2. The inside of the protective cover 1 is provided with a buckle assembly. The outer wall of the buckle assembly is fixedly connected to a bracket 9. The outer wall of the bracket 9 is provided with a buckle strip 13. The left side of the buckle strip 13 has a first buckle opening 10, a second buckle opening 11, and a third buckle opening 12. The outer wall of the bracket 9 is fixedly connected to a soft pad 14. Specifically, the protective cover 1 has a slot 2 for fixing the card plate 3, the bracket 9 is used to connect the card strip 13, the card strip 13 is used to open the first slot 10, the second slot 11, and the third slot 12 to adjust the size of the bracket 9, and the bracket 9 is used to fix the soft pad 14. The soft pad 14 improves the comfort of the operator.

[0019] Reference Figures 3-5 The buckle assembly includes a buckle plate 3, the outer wall of the buckle plate 3 is set on the inner wall of the buckle groove 2, the buckle plate 3 has an inner groove 4, the inner wall of the inner groove 4 is provided with a spring 5, the left outer wall of the spring 5 is fixedly connected to a buckle post 6, the outer wall of the buckle post 6 is fixedly connected to a push block 7, the left outer wall of the buckle plate 3 has a sliding groove 8, and the outer wall of the push block 7 is slidably connected to the inner wall of the sliding groove 8. Specifically, the clamping plate 3 is used to clamp onto the inner wall of the clamping slot 2. The clamping plate 3 has an inner groove 4 for holding the spring 5. The spring 5 drives the clamping post 6 to extend and slide. The clamping post 6 is used to fix the pushing block 7. The pushing block 7 drives the clamping post 6 to slide. The sliding groove 8 supports the pushing block 7 to slide on the inner wall of the sliding groove 8. This allows for quick disassembly and replacement of the protective cover 1, making it convenient for construction personnel to clean the protective cover 1 and improving the comfort of construction personnel.

[0020] Reference Figures 3-5 The protective cover 1 is composed of an impact layer 15 and a filter layer 16. The impact layer 15 is made of polycarbonate, and the filter layer 16 is made of nano-activated carbon. The outer wall of the bracket 9 is set on the inner wall of the first bayonet 10, and the outer wall of the locking post 6 is slidably connected to the inner wall of the inner groove 4. Specifically, the protective cover 1 is composed of an impact layer 15 and a filter layer 16. Polycarbonate has excellent resistance and high light transmittance, preventing corrosion from contacted chemicals. Nano-grade activated carbon has an extremely fine pore structure, which can quickly and effectively adsorb various harmful gases and tiny particles. The first bayonet 10 serves to fix the bracket 9 on the inner wall of the first bayonet 10. The inner groove 4 serves to support the bracket 9 to slide on the inner wall of the inner groove 4, thereby avoiding the splashing of raw materials onto the face due to accidents, providing clean air for construction personnel, and ensuring the safety of construction personnel.

[0021] Working principle: When the headgear used for safe construction of the oil refining unit is required, first push the push block 7 to drive the locking column 6 to slide on the inner wall of the slide groove 8. Then, the sliding of the locking column 6 will drive the spring 5 to contract. By pulling out the bracket 9, the locking plate 3 will be driven away from the slot 2, so that the protective cover 1 is separated from the bracket 9. The size of the bracket 9 and the locking strip 13 can be adjusted arbitrarily by using the first locking slot 10, the second locking slot 11, and the third locking slot 12. The soft pad 14 is used to clamp on both sides of the construction personnel, so as to achieve quick disassembly and replacement of the protective cover 1. It is convenient for the construction personnel to clean the protective cover 1 and improve the comfort of the construction personnel. The impact layer 15 prevents corrosion from contact with chemical substances, and the filter layer 16 effectively adsorbs various harmful gases and small particles, thereby avoiding the splashing of raw materials on the face due to accidents and ensuring the safety of the construction personnel.
