Abstract
The invention relates to the field of photoelectric technologies, in particular to a photoelectric sensor in the photoelectric field. The sensor comprises a tapered shell and a photoreceptor, wherein the diameter of an upper-end opening of the tapered shell is greater than that of a lower-end opening of the tapered shell; the photoreceptor is located in the tapered shell; the shell is internally provided with a supporting plate for bearing the photoreceptor; the upper-end opening of the tapered shell is provided with a light-transmitting cover plate; the lower end surface of the supporting plate is fixedly provided with an erection column on which a locking nut matched with the erection column is arranged; and the tapered shell is light-proof. The photoelectric sensor can be used for protecting the photoreceptor and receiving light within a certain range, and is simple in structure and convenient to mount and dismount; and the photoreceptor can not be damaged after the photoelectric sensor is used for a long time, so that the service life of the photoelectric sensor is prolonged.
Description
Technical field
The present invention relates to field of photoelectric technology, be specifically related to a kind of photoelectric sensor in the photoelectric field.
Background technology
The structure of existing photoelectric sensor is: only comprise a photoreceptor, it exposes and outside light is received, and such structure is after long-time the use; Be easy to cause the damage of photoreceptor; Shortened serviceable life, exposed photoreceptor can receive the light that needs beyond the scope simultaneously, thus the operate as normal of stray light electric transducer; And photoreceptor can produce certain heat after working long hours, and can influence the photosensitive effect of photoreceptor.
Summary of the invention
To above-mentioned technical matters, the present invention provides a kind of photoelectric sensor, can protect photoreceptor, and can receive the light of certain limit, and it is simple in structure, be convenient to installing/dismounting, and after long-time the use, photoreceptor can not damage, and prolongs its serviceable life.
Realize that technical scheme of the present invention is following:
A kind of photoelectric sensor; This sensor comprises the conical shell of open upper end diameter greater than the lower ending opening diameter, is positioned at the photoreceptor of conical shell, in housing, is provided with the back up pad of carrying photoreceptor; Open upper end at conical shell is provided with euphotic cover plate; Said back up pad lower surface is set with erection column, and erection column is provided with the set nut that is mated, and said conical shell is light tight housing.
The lower ending opening of said conical shell is provided with the spacing platform that extends to the center, leaves mounting hole at spacing platform middle part, and the upper end of above-mentioned erection column is fixedly connected back up pad, and above-mentioned mounting hole is passed in the lower end, and said set nut is positioned at the lower end of erection column.
Said euphotic cover plate is threaded with conical shell, is convenient to installing/dismounting.
Said euphotic cover plate upper surface is provided with access recess, is placed in the access recess with two bottle openers or finger and rotates, and just can euphotic cover plate screwed off or install, and is very convenient.
Offer away line three-way hole on the said back up pad, the axis direction of erection column is provided with the heat radiation through hole, and the said line three-way hole of walking is connected with the heat radiation through hole.The lead that is connected with photoreceptor is drawn from walk line three-way hole and heat radiation through hole, makes photoelectric sensor neat and artistic.
Said back up pad is the aluminium material back up pad, and erection column is copper erection column.
Adopted such scheme, when mounted, photoreceptor has been fixed on the back up pad, back up pad has been stuck in the conical shell again, the erection column lower end is passed from the mounting hole at spacing platform middle part, screws on euphotic cover plate and promptly accomplishes the photoelectric sensor assembling; In the time of on attaching it to use equipment, on the equipment that uses, offer a mounting hole, erection column passes this mounting hole, promptly can photoelectric sensor be installed on the equipment screwing on set nut; The assurance of conical shell the sensitive volume of photoreceptor, make photoreceptor not disturbed by the outer light of sensitive volume, guarantee the operate as normal of photoelectric sensor; The present invention can protect photoreceptor, and can receive the light of certain limit, and it is simple in structure, be convenient to installing/dismounting, and after long-time the use, photoreceptor can not damage, and prolongs its serviceable life.
