Technical Field

[0001] The utility model belongs to the technical field of gas alarms, and in particular relates to an industrial gas alarm which is easy to assemble and disassemble. Background Art

[0002] An industrial gas alarm is a device used to detect gas leaks in industrial environments. It mainly sounds an alarm by sensing changes in the concentration of the gas to ensure the safety of industrial sites. The working principle of industrial gas alarms is generally divided into two types: catalytic combustion type and electrochemical type. Catalytic combustion type alarms use the heat generated when the combustible gas burns under the action of a catalyst to cause temperature changes in the detector, thereby outputting an electrical signal. This type of alarm is generally suitable for detecting combustible gases such as methane and propane. Electrochemical alarms use combustible gases to generate electrical signals through electrochemical reactions, and then determine the concentration of the combustible gas by measuring the strength of the electrical signal. This type of alarm is generally suitable for detecting combustible gases such as hydrogen and carbon monoxide.

[0003] In the prior art, industrial gas alarms are mainly installed and fixed by means of screws and nuts during use, and require the use of an external wrench for operation. The operation is complicated and the installation is troublesome, and the same operation is required for disassembly. The entire disassembly and assembly process will consume a long time and energy, which is not conducive to the timely use of the gas alarm, which may lead to low disassembly and assembly efficiency and increase the workload of the staff.

[0004] Therefore, there is a need for an industrial gas alarm that is easy to disassemble and assemble, so as to solve the problems in the prior art of low disassembly and assembly efficiency and increased workload of staff. Utility Model Content

DETAILED DESCRIPTION

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] See also Figure 1-4 The utility model provides an industrial gas alarm which is easy to disassemble and assemble, including a mounting seat 1, a mounting block 2, an alarm body 3, a guide block 4, a mounting mechanism 5 and a disassembly mechanism 6.

The mounting mechanism 5 is symmetrically arranged on the left and right sides of the mounting groove. The disassembly mechanism 6 is arranged on the back of the mounting seat 1.

[0022] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that the mounting mechanism 5 is composed of a trapezoidal protrusion 502, a spring 503 and a positioning block 504, and the fixing grooves 501 are symmetrically opened on the left and right sides of the mounting groove, the trapezoidal protrusion 502 is fixedly connected to one side of the fixing groove 501, the spring 503 is fixedly connected to the inside of the fixing groove 501, the positioning block 504 is fixedly connected to the other end of the spring 503, and the positioning block 504 is slidably connected to the trapezoidal protrusion 502.

[0023] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth specifically explaining that grooves adapted to the guide block 4 are symmetrically opened on the upper and lower sides of the back of the alarm body 3, and trapezoidal grooves adapted to the trapezoidal protrusions 502 are symmetrically opened on the left and right sides of the back of the alarm body 3;

[0024] By means of the provided guide block 4 and the trapezoidal protrusion 502 , the alarm body 3 can be aligned therewith first, so as to ensure the next connection operation of the alarm body 3 .

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the front of the positioning block 504 is provided with an inclined surface, and the inside of the trapezoidal groove is provided with a positioning hole 505;

[0026] The inclined surface makes it easier for the alarm body 3 to press the positioning block 504, thereby improving the practicability of the mechanism.

[0027] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth specifically explaining that the disassembly mechanism 6 consists of a rotating block 601, a connecting shaft 602, a bevel gear set 603, a bidirectional threaded rod 604, a threaded block 605 and a push block 606. The rotating block 601 is rotatably connected to the top of the mounting seat 1, the connecting shaft 602 is fixedly connected to the bottom surface of the rotating block 601, the bevel gear set 603 is arranged below the connecting shaft 602, the bidirectional threaded rod 604 is arranged on one side of the bevel gear set 603, the threaded block 605 is symmetrically threadedly connected to the threaded surface of the bidirectional threaded rod 604, the threaded block 605 is slidably connected to the mounting groove, and the push block 606 is fixedly connected to one side of the threaded block 605 close to the positioning block 504, and the size of the push block 606 is smaller than the positioning hole 505;

[0028] By rotating the bidirectional threaded rod 604 , the two threaded blocks 605 are driven to move toward each other, and the push block 606 is driven to move inside the positioning hole 505 , thereby pushing the internal guide block 4 500 .

[0029] Further as Figure 1 , Figure 2 and Figure 4 As shown, it is worth explaining in detail that the bevel gear set 603 includes a driving bevel gear and a driven bevel gear, the bottom end of the connecting shaft 602 is fixedly connected with the driving bevel gear, the right end of the bidirectional threaded rod 604 is fixedly connected with the driven bevel gear, and the driving bevel gear is meshed with the driven bevel gear.

[0030] This solution has the following working process: when in use, the mounting base 1 is fixedly installed by threading the threaded hole inside the mounting block 2 with the target mounting hole, and then the groove and trapezoidal groove on the back of the alarm body 3 are aligned with the guide block 4 and the trapezoidal protrusion 502 respectively, and the alarm body 3 is installed on the front of the mounting base 1. When the trapezoidal groove contacts the positioning block 504, the positioning block 504 is squeezed until the positioning block 504 is driven by the elastic action of the spring 503 to extend into the interior of the positioning hole 505 to fix the installation of the alarm body 3; when the alarm body 3 needs to be disassembled, the rotating block 601 is rotated to connect the alarm body 3. The connecting shaft 602 drives the bevel gear set 603 to rotate, and at the same time drives the bidirectional threaded rod 604 to rotate, and drives the push block 606 to move in the direction of the positioning block 504 through the threaded block 605. At the same time, the push block 606 moves inside the positioning hole 505 to push the positioning block 504 until the positioning block 504 is completely retracted into the trapezoidal protrusion 502, thereby releasing the fixation of the alarm body 3, and then pushing the alarm body 3 outward, limiting the positioning block 504 through the back side of the alarm body 3, and then rotating the rotating block 601 in the opposite direction to drive the push block 606 to move out of the positioning hole 505, so that the alarm body 3 can be completely disassembled.

[0031] In summary: through the installation mechanism 5 and the disassembly mechanism 6, the positioning block 504 can be inserted into the inside of the positioning hole 505 to fix the connection between the mounting base 1 and the alarm body 3, and then the positioning block 504 can be pushed through 607 to release the connection of the positioning block 504 and disassemble the alarm body 3. This process is simple and convenient to operate, which can effectively shorten the time spent on the installation of the gas alarm body 3 and facilitate the timely use of the gas alarm body 3.
