Description

Technical Field

[0001] The utility model relates to the technical field of fire detectors, in particular to a fire detector which is easy to install. Background Art

[0002] A fire detector is a safety device used to detect and warn of fire. It determines whether a fire has occurred by sensing smoke, temperature and some flame parameters in the environment, and sends out an alarm signal in time so that people can take appropriate countermeasures. By discovering fires in advance and taking timely measures to extinguish fires or evacuate people, it can reduce casualties and property losses caused by fires. It is widely used in various places, including residences, commercial buildings, factories and schools.

[0003] In the prior art, since there are some electronic components installed inside the fire detector, it is easy to be accidentally touched by people when it is installed at a low height, and it will occupy the space of the public area and cause inconvenience when it is installed at a high height. When it is installed at a high position, it is often unable to provide escape assistance to the escapees in the event of a fire, and its practicality is poor. Therefore, technical personnel in this field provide a fire detector that is easy to install to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a fire detector that is easy to install.

The fixed frame has a detector body fixedly arranged at the front end, and an alarm indicator light is fixedly arranged at the lower front end of the detector body.

[0008] Through the above technical scheme, the detector body inside the descending mechanism can be installed on the wall through the fixing mechanism and the descending mechanism, and can be easily installed and removed through the clamping plate and the clamping frame. At the same time, the detector body is arranged at a higher position on the wall to avoid occupying public space and being accidentally touched in life. In the event of a fire, the descending mechanism can be automatically triggered by heat to drive the detector to descend, which is convenient for escapees to find the detector when they bend over, and the alarm indicator light prompts the escape route of the escapee, providing protection for safe escape.

[0009] Furthermore, the fixing frame is provided with cutting grooves on both sides of the middle, the upper ends of the two cutting grooves are fixedly provided with thermally variable pads, and the lower ends of the two cutting grooves are fixedly provided with metal knives;

[0010] Through the above technical solution, the metal knife can move toward the thermally variable gasket when it expands due to heat, and the positioning line is arranged between the metal knife and the thermally variable gasket, so that the positioning line can be cut off after heating.

[0011] Furthermore, two alignment balls are fixedly arranged on both sides of the rear end of the fixing frame, and positioning lines are fixedly connected between two of the four alignment balls;

[0012] Through the above technical solution, the positioning line passes through the lifting slider, the sliding bar and the connecting block, so that it is fixed at the lower end of the fixed frame. When an emergency occurs, the positioning line is disconnected to quickly move the lifting slider, the sliding bar and the connecting block to lower the detector body, thereby providing assistance to the escapee.

[0013] Furthermore, a connecting block is slidably arranged inside the two sliding bars, and the two connecting blocks are respectively fixedly arranged on both sides of the front end of the sliding plate;

[0016] Through the above technical solution, during the installation of the descending mechanism and the fixing mechanism, the installation effect can be improved by inserting the connecting ball into the inside of the connecting groove, thereby improving the stability of the installation.

[0017] Furthermore, four fixing holes are provided between the front and rear ends of the fixing plate and close to the upper and lower parts;

[0018] Through the above technical solution, the fixing plate can be installed and connected through the fixing hole.

[0019] Furthermore, a heat absorbing block is fixedly provided at the lower ends of the two metal knives;

[0020] Through the above technical solution, the heat absorption block can better transfer the temperature of the surrounding environment to the inside of the metal knife, thereby improving the accuracy of thermal sensing.

In addition, the detector is also equipped with an alarm indicator light to clearly indicate the escape route, thereby providing important protection for safe escape.

[0023] 2. The utility model proposes a fire detector which is easy to install. A positioning line is arranged inside the detector and passes through a lifting slider, a sliding bar and a connecting block so that the detector is fixed at a lower end inside a fixed frame. The positioning line is arranged between a metal knife and a thermally variable gasket. When the metal knife expands due to heat, it can move toward the thermally variable gasket to cut off the positioning line, quickly move the lifting slider, the sliding bar and the connecting block, and lower the detector body, so as to provide assistance to escapees. A heat absorbing block is arranged under the metal knife, so as to better transfer the temperature of the surrounding environment to the inside of the metal knife, thereby improving the accuracy of heat sensing.
