DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] The utility model provides Figure 1-4The chemical hazardous gas leakage warning device shown in the figure includes an early warning device body 1, a groove is provided on the back of the early warning device body 1, and the groove is used to limit the position of the first mounting plate 201 and the second mounting plate 202 through the insertion of a movable plate 302. The outer wall of the early warning device body 1 is provided with a mounting structure 2, and the mounting structure 2 includes a first mounting plate 201 and a second mounting plate 202. The outer wall of the first mounting plate 201 is fixedly provided with a fixing plate 206 connected to the mounting wall, and the second mounting plate 202 is fixedly provided on the back of the early warning device body 1. The second mounting plate 202 is movably provided with a mounting hook 203 for hanging the early warning device body 1, and the outer wall of the second mounting plate 202 is provided with a movable groove, and the bottom end of the mounting hook 203 The movable plate 302 is rotatably interlaced with the inner wall of the movable groove. When the first mounting plate 201 and the second mounting plate 202 are in use, the first mounting plate 201 and the second mounting plate 202 are fitted together. When the first mounting plate 201 is close to the second mounting plate 202, the movable plate 302 will move along the inner cavity of the movable groove on the second mounting plate 202. As the first mounting plate 201 and the second mounting plate 202 are pressed together, the first suction plate 204 fixed on the movable plate 302 will be close to the second suction plate 205. Therefore, after the first mounting plate 201 and the second mounting plate 202 are pressed together, the first suction plate 204 and the second suction plate 205 will also be adsorbed and fixed, so that the first mounting plate 201 and the second mounting plate 202 are conducive to the first suction plate 204 and the second suction plate 2 05, and then the first mounting plate 201 is fixed on the mounting surface by adsorption by the fixing plate 206. The fixing plate 206 is a plastic suction cup with good adsorption, so that the position of the early warning device body 1 can be installed. In this process, as the first mounting plate 201 and the second mounting plate 202 approach each other, the top of the mounting hook 203 will rotate from the initial direction toward the first mounting plate 201 to the side direction of the early warning device body 1, thereby avoiding affecting the installation between the early warning device body 1 and the mounting surface. Conversely, when the mounting surface of the early warning device body 1 is in an arc state, the mounting hook 203 can be used to suspend and fix the position without using the first mounting plate 201, thereby making the early warning device body The body 1 can be applied to a variety of installation environments, which improves the convenience of installing the alarm body 1. At the same time, the structures of the mounting structure 2 are cleverly arranged. In a flat installation environment, the mounting hook 203 can rotate with the fit of the first mounting plate 201 and the second mounting plate 202, avoiding increasing the distance between the alarm body 1 and the installation plane, and ensuring the effectiveness of the fixed plate 206 in driving the installation of the alarm body 1. In an arc surface installation environment, the first mounting plate 201 can be moved out, and in the process of moving away from the second mounting plate 202, the mounting hook 203 is driven to rotate in the opposite direction, so that the mounting hook 203 is hung toward the installation surface. The coordination between the structures improves the flexibility and practicality of the disassembly and assembly of the alarm body 1.

[0030] Furthermore, a movable structure 3 for changing the direction of the mounting hook 203 is provided between the first mounting plate 201 and the second mounting plate 202. The movable structure 3 includes a movable tooth ring 301 and a movable plate 302. The movable tooth ring 301 is fixedly sleeved on the outer wall of the mounting hook 203. The movable plate 302 is fixedly provided on the end of the first mounting plate 201 close to the second mounting plate 202. A plurality of tooth grooves 303 are provided on the end surface of the movable plate 302 close to the movable tooth ring 301. When the movable plate 302 moves, the tooth grooves 303 are engaged with the outer wall of the movable tooth ring 301, and then the mounting hook 203 is driven to rotate. The movable tooth ring 301 rotates in mesh with the tooth groove 303 as the movable plate 302 moves. Since the movable tooth ring 301 is fixed to the mounting hook 203, the mounting hook 203 will be driven to rotate when the movable tooth ring 301 rotates. The movable plate 302 is not only used to drive the rotation of the movable tooth ring 301, but also can be connected with the groove provided on the back of the alarm body 1 through insertion, and at the same time, the first suction plate 204 and the second suction plate 205 are driven to connect during the through insertion connection, so as to ensure the use of the first mounting plate 201 and the mounting hook 203, thereby providing structural support for the installation of the alarm body 1 in different environments;

[0031] Furthermore, the mounting structure 2 further includes a first suction plate 204 and a second suction plate 205. The first suction plate 204 is fixedly arranged at the end of the movable plate 302 away from the first mounting plate 201, and the second suction plate 205 is fixedly arranged on the back of the alarm body 1. The second suction plate 205 is magnetically adsorbed or adhered to the first suction plate 204. The first suction plate 204 and the second suction plate 205 are either magnetic suction plates or glue plates. The first suction plate 204 and the second suction plate 205 can be magnetically adsorbed or adhesively fixed, and both can provide support for the fixation between the first mounting plate 201 and the second mounting plate 202, thereby ensuring the effectiveness of the fastening between the first mounting plate 201 and the second mounting plate 202.

[0032] Finally, a positioning structure 4 is provided between the first mounting plate 201 and the second mounting plate 202, and the positioning structure 4 includes a positioning rod 401 and a positioning groove 402. The positioning rod 401 is fixedly provided on the end face of the first mounting plate 201 close to the second mounting plate 202, and the positioning rod 401 is used for the accurate fit of the first mounting plate 201 and the second mounting plate 202, and the positioning groove 402 is provided on the end face of the second mounting plate 202 away from the early warning device body 1, and the positioning groove 402 provides a moving space for the positioning rod 401, and the positioning rod 401 and the positioning groove 402 are gradually connected with each other as the first mounting plate 201 and the second mounting plate 202 approach each other. The setting of the positioning rod 401 and the positioning groove 402 provides the accuracy of the position fit between the first mounting plate 201 and the second mounting plate 202, so that the first mounting plate 201 and the second mounting plate 202 can be aligned and used closely, thereby ensuring the accuracy of the activity trajectory of the movable plate 302 and improving the stability of the fit between the first mounting plate 201 and the second mounting plate 202.
