Abstract
The utility model discloses a flame detector with an improved photoresistor protection method. The flame detector is characterized by improving and designing a nylon sleeve structure, and through an arc positioning structure on a front end of the nylon sleeve, four freedom degrees of a photoresistor on an up-and-down direction, a left-and-right direction and rotation on the two directions are restricted. The arc in the arc positioning structure refers to an arc exceeds one half and is an incomplete arc. Adding two freedom degrees of the photoresistor on an anterio-posterior direction and rotation on the direction, the detector realizes restriction on the six freedom degrees of the photoresistor, thereby effectively fixing a position of the photoresistor, reducing freedom degrees thereof, so as to prevent the photoresistor from colliding with a protective tube and fragmenting in transportation or in use.
Description
Technical field
The utility model relates to a kind of flame detector, particularly the protected mode of the inner photoresistance of flame detector.
Background technology
In flame detector; photoresistance is mainly realized its location and protection by nylon jacket and containment vessel; wherein containment vessel mainly plays attractive in appearance, dustproof and the effect that prevents that photoresistance and other things from directly contacting; and nylon jacket mainly plays the circuit of fixedly photoresistance and limits its former and later two degree of freedom; but in daily transportation and using; photoresistance is easily because of concuss and containment vessel generation collision fragmentation; therefore; for more effective protection photoresistance, need a kind of more effectively protected mode.
Summary of the invention
The purpose of this utility model is to improve the protected mode of flame detector photoresistance, makes photoresistance obtain more effective safer protection.
The technical solution of the utility model is: by improving the effectively fixedly photoresistance of structure of nylon jacket, prevent that it from producing collision because of concuss and containment vessel.
Principle of the present utility model is: always photoresistance has 6 degree of freedom, if all limited, its locus is exactly unique.Therefore, limit its 6 degree of freedom by the nylon jacket new construction, can effectively prevent from producing between itself and the containment vessel collision.
The beneficial effects of the utility model are: improved the photoresistance safe class of flame detector, reduced its transportation and request for utilization grade.
Description of drawings
Accompanying drawing 1 is front view of the present utility model.
Accompanying drawing 2 is the utility model vertical view.
Accompanying drawing 3 is the front view of the utility model place flame detector main body, the 1st, and transparent outer cover, the 2nd, photoresistance, the 3rd, nylon jacket, the 4th, protecting sheathing.
Embodiment
Below in conjunction with accompanying drawing the utility model is made further explanation.
Nylon jacket is in flame detector, circular arc location structure by the nylon jacket front end, the circular arc of described circular arc location structure indication is for surpassing 1/2 circular arc, it is incomplete circular arc, the restriction photoresistance about, about and four degree of freedom of the rotation on this both direction, add the front and back of restriction photoresistance on the original structure and two degree of freedom of rotation that the party makes progress, realize the restriction to 6 degree of freedom of photoresistance.
Above-described specific embodiment, the present embodiment that it should be understood that only provides a kind of method of architecture advances, allows the personage who is familiar with this structure understand and to use.All any modifications of within spirit of the present utility model and principle, making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
Claims (1)
1. flame detector that improves the photoresistance protected mode, it is characterized in that: improve design nylon jacket structure, circular arc location structure by the nylon jacket front end, the circular arc of described circular arc location structure indication is for surpassing 1/2 circular arc, it is incomplete circular arc, the restriction photoresistance about, about and four degree of freedom of the rotation on this both direction, add the front and back of restriction photoresistance on the original structure and two degree of freedom of rotation that the party makes progress, realize the restriction to 6 degree of freedom of photoresistance; Thereby prevent to greatest extent bumping between photoresistance and the containment vessel and cracked, guarantee photoresistance in transportation and the safety in using.
