Description

Technical Field

[0001] The utility model relates to the technical field of photoelectric switches, and particularly relates to a protection structure applied to a photoelectric switch. Background Technique

[0002] A photoelectric switch is short for a photoelectric proximity switch. It uses the occlusion or reflection of a light beam by a detected object to connect a circuit through a synchronous circuit, thereby detecting the presence or absence of an object. The object is not limited to metal, and all objects that can reflect light can be detected.

[0003] Since a photoelectric switch is usually fixed on a device using a bracket, and the bracket often has no protection device. When not in use, if it comes into contact with an object, it is very easy to cause damage to the photoelectric switch; moreover, since some detection doors are usually in a closed state, a large amount of dust will accumulate on the surface of the photoelectric switch after long-term non-use, affecting later use. Therefore, a protection structure applied to a photoelectric switch is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a protection structure applied to a photoelectric switch to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A protection structure applied to a photoelectric switch, including a backboard, a protective cover, a detection port and a photoelectric switch body. Fixed plates are provided on both sides of the backboard, fixing holes are opened on the surface of the fixed plates, shock-absorbing rubber blocks are provided on both sides of the surface of the backboard, the protective cover is installed on the surface of the shock-absorbing rubber blocks, the photoelectric switch body is installed on the inner cavity wall surface of the protective cover, a reagent kit is provided on the surface of one inner cavity wall of the protective cover, protective plates are provided on the four surrounding sides of the protective cover, a protective cover is installed on the front of the protective cover, a detection port is provided on the surface of the protective cover, a cover plate is installed on the surface of the detection port, and a connection port is opened on one side surface of the protective cover.

[0006] Preferably, a plurality of second springs are connected between the middle of the back surface of the protective cover and the surface of the backboard.

[0007] Preferably, the photoelectric switch body is fixedly connected to the inner cavity wall surface of the protective cover through fixing bolts.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: The present utility model installs the photoelectric switch body inside the protective cover. The protective cover and the cover plate can effectively protect the photoelectric switch, preventing the photoelectric switch from being damaged artificially when not in use, which is different from the traditional bracket that directly exposes the photoelectric switch to the external environment, thus possibly causing damage; by arranging a second spring and a shock-absorbing rubber block on the back of the protective cover, and arranging a first spring, a protective plate and a buffer sponge on the side of the protective cover, that is, through the deformation of the first spring, the second spring, the shock-absorbing rubber block and the buffer sponge, the external impact received by the protective cover is absorbed, solving the problem that the photoelectric switch is easily damaged by direct impact; by arranging a cover plate at the detection port, when the photoelectric switch body is not in use, the detection port is closed by the cover plate, thereby dust-proofing the photoelectric switch and preventing excessive external dust from affecting the normal use of the photoelectric switch.
