Description

Technical Field

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

[0002] Chemical safety helmets are essential personal protective equipment used in the chemical industry to protect the head from injury. They have high impact strength, stable chemical properties, and good electrical insulation properties, and can effectively resist certain impacts and punctures. They are widely used in chemical and other industries.

[0003] In the prior art, such as Chinese patent CN218278787U, a novel chemical safety helmet is disclosed, comprising a main body, a protective shell at the upper end of the main body, a lighting device on one side of the protective shell, an air supply device at the bottom of the protective shell, a brim at the lower end of the main body, and a controller at the front end of the main body. This utility model, through the combined action of a battery, threaded rod, control module, outer shell, light-emitting element, and lead post, facilitates use by workers in dimly lit environments, improving the practicality of the safety helmet and achieving long-term illumination, thus ensuring worker safety. The combined action of the mounting base, air supply fan, pipe, air supply duct, and mesh achieves a cooling effect, preventing the user from experiencing stuffiness and protecting their body. Furthermore, the air supply disperses the odors produced by chemical raw materials, making them less likely to be inhaled by the user.

[0004] In the aforementioned patent, the combined effect of the battery, threaded rod, control module, outer cover, light-emitting element, and guide post makes it easier for workers to use in dark environments, improving the practicality of the safety helmet. However, during use, the illumination angle of the light-emitting element cannot be adjusted, and workers must adjust their body position to obtain better lighting effects, increasing the complexity of operation and making it easy to cause operational errors. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the above-mentioned patent, where the safety helmet is easy for workers to use in dark environments through the combined action of the battery, threaded rod, control module, outer cover, light-emitting element and guide post, thus improving the practicality of the safety helmet. However, during use, the illumination angle of the light-emitting element cannot be adjusted, and workers have to adjust their body position to obtain a better lighting effect, which increases the complexity of operation and is prone to operational errors. Therefore, this utility model proposes a chemical safety helmet.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a safety helmet for chemical use, comprising a safety helmet body, wherein an installation component is fixedly connected to the outer surface of the safety helmet body, and an adjustment component is provided on the inner surface of the installation component;

[0007] The adjustment assembly includes a fixed frame, a worm gear that movably passes through the top of the fixed frame, a rotating rod that is rotatably connected to the inner surface of the fixed frame, a connecting block that is fixedly connected to the center of the outer surface of the rotating rod, a light that is fixedly connected to the front surface of the connecting block, a worm wheel that is fixedly connected to the outer surface of the rotating rod near the edge, and a limit groove that is formed on the outer surface of the fixed frame near the bottom.

[0008] The mounting assembly includes a mounting base, a mounting frame is fixedly connected to the inner bottom of the mounting base, a rotating shaft is rotatably connected to the inner surface of the mounting frame, and a limiting member is fixedly connected to the outer surface of the rotating shaft.

[0009] Preferably, the outer surface of the fixing frame mates with the inner surface of the mounting base, and the two limiting members mate with the inner surface of the limiting groove, respectively.

[0010] Preferably, a connecting rod is symmetrically and movably inserted through the center of the front surface of the mounting base, and a toothed plate is fixedly connected between the rear end faces of the two connecting rods.

[0011] Preferably, the outer surfaces of the two sides of the toothed plate engage with the outer surfaces of the two limiting members respectively, and a pull block is fixedly connected between the front ends of the two connecting rods.

[0012] Preferably, springs are symmetrically fixedly connected to the inner surface of the toothed plate, and the rear end faces of the two springs are fixedly connected to the inner wall of one side of the mounting base.

[0013] Preferably, the bottom of the mounting base is fixedly connected to the top of the helmet body, and the outer surface of the worm gear meshes with the outer surface of the worm.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, when the angle of the lighting needs to be adjusted, the worm gear can be rotated, causing it to rotate inside the fixed frame, which in turn drives the worm wheel to rotate, thereby rotating the rotating rod and adjusting the angle of the connecting block and the lighting. It also has a self-locking property, preventing the angle of the lighting from changing due to external force or vibration, thus improving the practicality and convenience of the safety helmet body in chemical environments. At the same time, simply pulling the pull block outward can move the toothed plate, causing the limiting part to rotate along the rotating shaft and move into the interior of the mounting frame, thereby facilitating the removal of the fixed frame from the mounting base and making it convenient for the maintenance or replacement of the lighting.

[0016] 2. In this utility model, by pulling the pull block to move the toothed plate outward, the spring will be stretched, causing the limiting member to move into the mounting bracket. Then, after the fixing bracket is inserted into the mounting base, the pull block is released. Under the action of the spring, the toothed plate will be reset, causing the limiting member to rotate out of the mounting bracket and move into the limiting groove, thus completing the installation of the fixing bracket. It has high practicality. Attached Figure Description

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, such as Figures 1-5 As shown, this utility model provides a safety helmet for chemical use, including a safety helmet body 1, an installation component 3 fixedly connected to the outer surface of the safety helmet body 1, and an adjustment component 2 provided on the inner surface of the installation component 3;

[0026] Adjustment component 2 includes a fixing frame 201, with a worm gear 202 movably passing through the top of the fixing frame 201. A rotating rod 206 is rotatably connected to the inner surface of the fixing frame 201. A connecting block 207 is fixedly connected to the center of the outer surface of the rotating rod 206. A light 204 is fixedly connected to the front surface of the connecting block 207. A worm wheel 203 is fixedly connected to the outer surface of the rotating rod 206 near its edge. A limiting groove 205 is formed on the outer surface of the fixing frame 201 near its bottom. Installation component 3 includes a mounting base 307, with a mounting bracket 304 fixedly connected to the inner bottom of the mounting base 307. A rotating shaft 303 is rotatably connected to the inner surface of the mounting bracket 304. A limiting member 302 is fixedly connected to the outer surface of the rotating shaft 303. The bottom of the mounting base 307 is fixedly connected to the top of the safety helmet body 1. The outer surface of the worm wheel 203 meshes with the outer surface of the worm gear 202.

[0027] The overall effect of Embodiment 1 is that when the worker wears the safety helmet body 1 stably on their head, the inner side of the fixing frame 201 is equipped with a battery and a matching switch on top for turning the lighting lamp 204 on and off. When the angle of the lighting lamp 204 needs to be adjusted, the worm gear 202 can be rotated, causing the worm gear 202 to rotate inside the fixing frame 201, driving the worm wheel 203 to rotate, causing the rotating rod 206 to rotate, thus adjusting the angle of the connecting block 207 and the lighting lamp 204. It also has a self-locking function to prevent changes in the angle of the lighting lamp 204 due to external forces or vibrations, thereby improving the practicality of the safety helmet body 1 in chemical environments. The fixture offers convenience, and when it is necessary to disassemble the mounting bracket 201 to replace or repair the internal lighting lamp 204, the pull block 308 can be pulled to move the connecting rod 301 outward, causing the toothed plate 306 to move outward. When the toothed plate 306 moves outward, the external tooth groove of the toothed plate 306 will cause the limiting member 302 to rotate along the rotating shaft 303, so that the protrusion of the limiting member 302 moves out of the limiting groove 205 and into the mounting bracket 304, so that the limiting member 302 is no longer stuck with the limiting groove 205. The fixture 201 can be quickly removed from the mounting base 307, which facilitates the maintenance or replacement of the lighting lamp 204 and has high practicality.

[0028] Example 2, as Figures 1-5As shown, the outer surface of the fixing bracket 201 mates with the inner surface of the mounting base 307, the two limiting members 302 mate with the inner surfaces of the limiting grooves 205 respectively, the connecting rods 301 are symmetrically and movably inserted through the center of the front surface of the mounting base 307, the toothed plates 306 are fixedly connected between the rear end faces of the two connecting rods 301, the outer surfaces of the two sides of the toothed plates 306 respectively mesh with the outer surfaces of the two limiting members 302, the pull blocks 308 are fixedly connected between the front end faces of the two connecting rods 301, the springs 305 are symmetrically fixedly connected to the inner surface of the toothed plates 306, and the rear end faces of the two springs 305 are fixedly connected to the inner wall of one side of the mounting base 307.

[0029] The effect achieved by the entire embodiment 2 is that during the installation of the lighting lamp 204, by pulling the pull block 308, the toothed plate 306 is moved outward, which will cause the spring 305 to be stretched, so that the limiting member 302 moves into the mounting bracket 304. Then, after the fixing bracket 201 is inserted into the mounting base 307, the pull block 308 is released. Under the action of the spring 305, the toothed plate 306 is reset, which causes the limiting member 302 to rotate out of the mounting bracket 304 and move into the limiting groove 205, thus completing the installation of the fixing bracket 201. It has high practicality.

[0030] Working Principle: When the worker wears the safety helmet 1 securely on their head, the inner side of the fixing frame 201 has a battery and a corresponding switch on top for turning the light 204 on and off. To adjust the angle of the light 204, the worm gear 202 can be rotated inside the fixing frame 201, causing the worm wheel 203 to rotate, which in turn rotates the rotating rod 206, adjusting the angle between the connecting block 207 and the light 204. This design also features a self-locking mechanism to prevent changes in the angle of the light 204 due to external force or vibration, improving the practicality and convenience of the safety helmet 1 in chemical environments. Furthermore, when the fixing frame 201 needs to be disassembled to replace or repair the internal light 204, the pull block 308 can be pulled, causing the connecting rod 301 to move outwards, which in turn moves the toothed plate 306 outwards. During lateral movement, the external toothed groove of the toothed plate 306 causes the limiting member 302 to rotate along the rotating shaft 303, causing the protrusion of the limiting member 302 to move out of the limiting groove 205 and into the mounting bracket 304. This disengages the limiting member 302 from the limiting groove 205, allowing the fixing bracket 201 to be quickly removed from the mounting base 307, thus facilitating the maintenance or replacement of the lighting lamp 204. When installing the lighting lamp 204, through... Pulling the pull block 308 moves the toothed plate 306 outward, which in turn stretches the spring 305, causing the limiting member 302 to move into the mounting bracket 304. Then, after inserting the fixing bracket 201 into the mounting base 307, releasing the pull block 308 causes the toothed plate 306 to reset under the action of the spring 305, causing the limiting member 302 to rotate out of the mounting bracket 304 and move into the limiting groove 205, thus completing the installation of the fixing bracket 201. This method is highly practical.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
