Description

Technical Field

[0001] The utility model relates to the technical field of gas leakage detection, in particular to a fixing fixture for a gas alarm. Background Art

[0002] Gas alarms are instruments that detect gas leaks and sound an alarm, such as combustible gas alarms, oxygen concentration alarms, carbon monoxide and carbon dioxide alarms, hydrogen sulfide gas alarms, etc. When flammable or toxic gas leaks in an industrial environment, when the gas leak alarm detects that the gas concentration reaches the critical point set by the explosion or poisoning alarm, the gas leak alarm will send out an alarm signal to remind workers to take safety measures. The gas leak alarm is equivalent to an automatic fire extinguisher, which can drive the exhaust, cut-off, and spray systems to prevent explosions, fires, and poisoning accidents, thereby ensuring safe production.

[0003] When calibrating a gas alarm on-site, a certain amount of standard gas needs to be released. The alarm probe (sensor) may be installed in a different position (for example, close to a wall), so the standard gas is not easy to directly contact the alarm probe (sensor). At the same time, the output of the standard gas is easy to diffuse and not concentrated. When the gas alarm detects gas, it is not so sensitive and it is easy to waste the standard gas.

[0023] By rotatably installing a movable plate 3 on the top of the mounting base plate 1, the orientation of the top alarm mounting plate 5 is adjusted by rotating the movable plate 3. At the same time, the angle between the alarm mounting plate 5 and the movable plate 3 can be adjusted through the cylinder 6 and the support seat 4, so that the alarm body 10 can be adjusted at multiple angles in a three-dimensional space. Then, the alarm mounting plate 5 can adjust its own spatial angle when the mounting screws 13 are released, so that the alarm body 10 can be adjusted at multiple angles, so that the sensor on the alarm body 10 can be adjusted in three-dimensional space, so as to avoid poor air flow at the sensor position, which causes the alarm body 10 to have a reduced sensitivity to gas detection.

[0024] The limit assembly 9 includes a support spring 91 sleeved on the outside of the cylinder 6 and the square column 7, the support spring 91 is located between the support seat 4 and the alarm mounting plate 5, one end of the support spring 91 is attached to a support plate 92 fixed to the outside of the square column 7, the support plate 92 is attached to the outside of the alarm mounting plate 5, the end of the cylinder 6 away from the alarm mounting plate 5 passes through the through hole and extends outward, the outside of the cylinder 6 is fixed with a fixing ring 93 located on the outside of the support seat 4, and the opposite side of the fixing ring 93 is fixed with two sets of counter-positioned limit The outer side of the support seat 4 is provided with a plurality of groups of positioning limit holes 95 around the through hole ring, and the limiting columns 94 are engaged with the limiting holes 95. By setting the support spring 91, the support seat 4 can be used to support the alarm mounting plate 5, and then the square column 7 and the square hole 8 are used to keep the cylinder 6 and the alarm mounting plate 5 rotating synchronously, so as to limit and fix the alarm mounting plate 5 by engaging the limiting columns 94 with the limiting holes 95, so as to prevent the alarm mounting plate 5 from shifting under the influence of gravity.

[0025] A receiving groove 11 is provided on the top of the mounting base 1, and the movable plate 3 is located in the inner cavity of the receiving groove 11. The provision of the receiving groove 11 facilitates the positioning of the movable plate 3 and ensures the stability between the movable plate 3 and the mounting base.

The inner cavity of the first fixing seat 53 is movably provided with a rotating shaft 55, and both ends of the rotating shaft 55 pass through the first fixing seat 53 and are fixed to the inner side of the second fixing seat 54. By setting the structure of the alarm mounting plate 5, it is convenient to install the alarm body 10 with four groups of mounting screws 13 at the same time, so that the alarm mounting plate 5 cannot be adjusted. However, when the front and rear two groups of mounting screws 13 are not installed synchronously, the alarm body 10 is installed on the first base 51 or the second base 52, which is convenient for adjusting the alarm body 10 in different directions and increasing the diversity of the sensor orientation on the alarm body 10.

At the same time, the pull ring 17 is pulled outward, and the cylinder 6 drives the square column 7 to move in the square hole 8. At the same time, the cylinder 6 drives the limiting column 94 to separate from the limiting hole 95 through the fixing ring 93, and then drives the cylinder 6 to rotate through the pull ring 17. The cylinder 6 drives the alarm mounting plate 5 to adjust the angle through the square column 7, and then the pull ring 17 is released.
