Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] like Figures 1 to 5As shown, this embodiment proposes a multifunctional gas detector, including a protective cover 1, with support shafts 2 rotatably connected to both sides of one end of the protective cover 1, a gas detector body 3 fixedly connected between the two support shafts 2, a limit assembly 4 fixedly connected to one side of the protective cover 1, the limit assembly 4 is used to limit the rotation of the gas detector body 3, the bottom end of the protective cover 1 is fixedly connected to a positioning seat 5, and positioning assemblies 6 are provided at both ends of the positioning seat 5, and the positioning assembly 6 is used to position the protective cover 1;

[0032] Furthermore, a cushion is fixedly connected to the inner side of the protective cover 1. The cushion is made of sponge. When the gas detector body 3 is moved into the inner side of the protective cover 1, the display unit and the operating unit of the gas detector body 3 are protected from damage.

[0033] The limiting assembly 4 includes a support plate 7, a central shaft 8, a limiting plate 9, a reset seat 10 and a linear slide 11. Two support plates 7 are fixedly connected to one side of the protective cover 1. The central shaft 8 is rotatably connected between the two support plates 7. The outer side of the central shaft 8 is fixedly connected to the limiting plate 9. The side where the two support plates 7 are away from each other is fixedly connected to the reset seat 10. The interior of the reset seat 10 is fixedly connected to the linear slide 11. The outer side of the linear slide 11 is slidably connected to the displacement seat 12. A coil spring 13 is fixedly connected between the bottom end of the displacement seat 12 and the reset seat 10. One end of the displacement seat 12 is rotatably connected to a linkage seat 14. Both ends of the central shaft 8 are fixedly connected to a force-bearing plate 15, and the linkage seat 14 is slidably connected to the outer side of the force-bearing plate 15.

[0034] Specifically, the middle parts of the two support plates 7 are provided with mounting holes, and the two ends of the central shaft 8 are respectively connected to the inside of the two mounting holes, and the inside of the mounting holes is provided with balls. The arrangement of the mounting holes enables the central shaft 8 to be stably assembled, and the arrangement of the balls can improve the smoothness of the central shaft 8 when connected;

[0035] Preferably, one end of the linkage seat 14 close to the linear slide rod 11 is fixedly connected to a linkage shaft, and the linkage seat 14 is rotatably connected to one end of the displacement seat 12 through the linkage shaft. Through the structural cooperation of the linkage shaft, the linkage seat 14 can be stably connected to the displacement seat 12;

[0036] Among them, the outer side of the load-bearing plate 15 is provided with a slide groove, and the linkage seat 14 is connected to the inside of the slide groove. The setting of the slide groove can effectively guide the sliding trajectory of the linkage seat 14 and prevent the linkage seat 14 from separating from the load-bearing plate 15;

[0037] Here, the end of the force-bearing plate 15 away from the central shaft 8 is fixedly connected to a force-bearing handle, and the outer side of the force-bearing handle is provided with anti-slip grooves. The force-bearing handle is provided to facilitate the gripping of the force-bearing plate 15 by a person;

[0038] Example 2

[0039] like Figures 1 to 5 As shown, based on the same concept as the above embodiment 1, this embodiment further proposes a positioning component 6;

[0040] In this embodiment, the positioning assembly 6 includes a flexible belt 16, a positioning plate 17, a Velcro A surface 18 and a Velcro B surface 19. One end of the positioning seat 5 is fixedly connected to the flexible belt 16, and the end of the positioning seat 5 away from the flexible belt 16 is rotatably connected to the positioning plate 17, and one end of the positioning plate 17 is buckled with the positioning seat 5. The side of the flexible belt 16 away from the positioning seat 5 is provided with the Velcro A surface 18, and the side of the positioning plate 17 close to the Velcro A surface 18 is provided with the Velcro B surface 19, and the Velcro B surface 19 is adhesively connected to the Velcro A surface 18;

[0041] Preferably, both sides of the positioning seat 5 away from the end of the flexible belt 16 are fixedly connected with assembly ears, and the positioning plate 17 is connected between the two assembly ears through a rotating shaft. The arrangement of the assembly ears can stably form a match with the rotating shaft;

[0042] In detail, the end of the positioning plate 17 away from the assembly ear is fixedly connected to the positioning buckle 20, and the side of the positioning seat 5 away from the assembly ear is fixedly connected to the positioning female buckle 21, and the positioning plate 17 is buckled with the positioning female buckle 21 through the positioning buckle 20. By utilizing the structural cooperation of the positioning buckle 20 and the positioning female buckle 21, after the positioning plate 17 is rotated, the position of the positioning plate 17 can be stably locked.

[0043] A specific application of the above two embodiments is as follows: first, the positioning seat 5 is placed on the inner arm of the person, and the protective cover 1 is tied to the person's arm through the flexible belt 16. Then, the positioning plate 17 is rotated downward, and the connection between the Velcro B surface 19 and the Velcro A surface 18 is coordinated to make the flexible belt 16 stick to the positioning plate 17. Then, the positioning buckle 20 is pressed and buckled into the positioning buckle 21, thereby locking the position of the positioning plate 17 and the position of the flexible belt 16, thereby preventing the protective cover 1 from being separated from the person's arm.

[0044] When using the gas detector body 3, first press the force plate 15 downward. Since the force plate 15 is supported by the central shaft 8, it can drive the limit plate 9 to flip upward, causing the limit plate 9 to break away from the contact with the gas detector body 3, thereby unlocking the gas detector body 3. Then rotate the gas detector body 3 upward so that it moves out of the inside of the protective cover 1 under the support of the support shaft 2. Then the personnel can hold the gas detector body 3 to operate, and cooperate with the connection between the force plate 15 and the linkage seat 14. During the rotation of the force plate 15, the linkage seat 14 will be pressed at the same time, causing the displacement seat 12 to slide on the outside of the linear slide rod 11 and squeeze the coil spring 13. When the force plate 15 is released, the limit plate 9 can be reset by the rebound of the coil spring 13.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
