Abstract
The utility model relates to a light pillar on a fire detector. The light pillar comprises a light pillar body and a diffusion face at the top end of the light pillar body. The light pillar on fire detector is characterized in that a bending end is arranged at the bottom of the light pillar, the bending end is provided with a limit groove and an aligning face for fixing, and the diffusion face is a spherical face. According to the light pillar on the fire detector, lamp light of the bending end is transmitted out of a casing through the light pillar, and a user can observe the lamp light of the indicator lamp of the fire detector. In addition, an aligning device and the limit groove which are arranged on the light pillar enable the light pillar to be directly fixed inside the detector without other fixing methods of welding and the like. Therefore, the light pillar on the fire detector can improve working efficiency during assembly, and is convenient to assemble and disassemble and firm to fix.
Description
[technical field]
The utility model relates to a kind of light-guiding pillar, is specifically related to the light-guiding pillar on a kind of fire detector.
[background technology]
Whether fire detector need to indicate with indicator lamp usually in normal operation, and indicator lamp is arranged on the wiring board of detector inside, and by light-guiding pillar light-output.
Domestic utility model CN201636768U discloses a kind of for the light-guiding pillar on fire detector, the top of light-guiding pillar is provided with astigmatic face, the mode of light-guiding pillar by rotary buckle is fixed on detector inside, this equipment need to arrange especially rotary buckle and be connected with light-guiding pillar on the support of fixing it of detector, may need to change whole fixed support in practical application, cause unnecessary trouble.
[summary of the invention]
In order to solve defects of the prior art and problem, the utility model provides a kind of easy light-guiding pillar that is arranged on fire detector.
For achieving the above object, design the light-guiding pillar on a kind of fire detector, comprise the astigmatic face on light-guiding pillar body and top thereof, it is characterized in that bottom described light-guiding pillar, bending end being set, described bending end is provided with for fixing stopper slot with to plane, and described astigmatic face is sphere.
The bending angle of described bending end is 90 degree.Bending end can effectively utilize the space of fire detector, and plays the effect of reinforcing astigmatic post.
Light-guiding pillar of the present utility model is delivered to the light of indicator lamp outside housing by this light-guiding pillar, the indicator lamp light that the user can the observable fire detector.In addition, this light-guiding pillar is provided with alignment device and stopper slot makes light-guiding pillar can directly be fixed on detector inside, and does not need welding to wait other fixed forms, the operating efficiency in the time of therefore can providing assembling, and installing/dismounting is also convenient, and is fixed.
