Description

Technical Field

[0001] This utility model belongs to the field of respirators, and specifically relates to an alarm device in a respirator. Background Technology

[0002] The alarm in a respirator is an essential part of the respirator, enabling workers to be alerted in dangerous situations and thus quickly rescued. However, when working with respirators, workers are often in high-temperature and high-risk areas. During the operation, the alarm may be bumped or dropped, causing it to malfunction and fail to sound the alarm in dangerous situations, leaving workers in danger. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing an alarm device for a respirator.

[0004] The purpose of this utility model can be achieved through the following technical solution: an alarm in a respirator, including an alarm body, an outer shell, and an inner shell installed inside the outer shell for housing several electronic components and modules, characterized in that the inner shell is composed of two interlocking shells and fixed by screws, and grooves for limiting and fixing with the outer shell are provided at both ends of the screw mounting position on the shell.

[0005] The outer shell is composed of two interlocking shells. The inner wall of the shell is provided with a limiting block that is mutually limiting and cooperating with the channel. The inner wall of the shell is provided with a number of support parts for supporting and reinforcing the shell.

[0006] In the alarm of the above-mentioned respirator, the support part is divided into a horizontally straight support part one and a support part two with forked ends in the empty space on the housing two.

[0007] In the alarm of the aforementioned respirator, the support part has two forked ends, which together with the two sides of the housing form a triangle.

[0008] In the alarm of the above-mentioned respirator, a heat insulation layer with the same shape as the housing is provided on the inner wall of the housing two and is fastened to the housing two.

[0009] In the alarm of the aforementioned respirator, the two housings are fixed together by bolts.

[0010] Compared with existing technologies, the alarm in this respirator has a reinforced overall structure through a support section and a heat insulation layer inside the shell, which increases the overall strength and high-temperature resistance. Attached Figure Description

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1 , Figure 2 , Figure 3 As shown, the alarm in this respirator includes an alarm body 8, an outer shell, and an inner shell installed inside the outer shell for housing several electronic components and modules. The inner shell consists of two interlocking shells 1 fixed by screws. At both ends of the screw mounting points on the shell 1, grooves 2 are provided for limiting and fixing with the outer shell.

[0017] The outer shell consists of two interlocking shells 3. The inner wall of the shell 3 is provided with a limiting block 4 that is mutually limiting and cooperating with the channel 2. The inner wall of the shell 3 is provided with several support parts for supporting and reinforcing the shell 3.

[0018] The housing 1 and housing 3 are mutually fixed by the channel 2 and the limiting block 4 to reduce the shaking of housing 1 inside housing 3 during use.

[0019] Preferably, the support portion in the empty space of the housing 23 is divided into a horizontally straight support portion 5 and a support portion 26 with forked ends. According to the remaining space in the housing 23, the support portion 5 is provided in the narrow space and the support portion 26 is provided in the more open space, so that the support portion 5 and the support portion 26 cover the housing 23, thereby increasing the strength of the housing 23.

[0020] Preferably, the support portion 2 6 is forked at both ends and forms a triangle together with the side of the housing 2 3. Since the triangle has stability, the support portion 2 6 can more effectively increase the strength of the housing 2 3.

[0021] Preferably, a heat insulation layer 7 with the same shape as the housing 3 and fastened to the housing 3 is provided on the inner wall of the housing 3 to increase heat resistance and reduce the occurrence of internal component failure caused by high temperature.

[0022] Preferably, the two housings are fixed together by bolts.

[0023] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0024] Although this document frequently uses terms such as shell 1, channel 2, shell 2, limiting block 4, support 1, support 2, heat insulation layer 7, and alarm body 8, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
