[0031] Photoelectric switch is the abbreviation of photoelectric proximity switch, which detects the presence or absence of an object by using the blocking or reflection of the light beam by the object to turn on the circuit by the synchronous circuit. The photoelectric switch is disturbed by many factors in the working area, such as water, dust, etc. In order to protect the photoelectric switch, a protective cover needs to be installed on the photoelectric switch to protect it.

[0032] In the related art, a protective shell is arranged outside the photoelectric switch. When the photoelectric switch is disassembled, the pressing rod needs to be pressed to rotate the rotating rod and push the clamping plate away at the same time to release the clamping of the protective shell. Then, the two pull rods on the protective shell are pulled to separate the clamping block from the connecting block, release the restriction on the photoelectric switch, and then the photoelectric switch can be taken out. However, the existing device needs to pull the two pull rods at the same time when disassembling, which is not convenient for taking out the photoelectric switch from the inside of the protective shell while pulling the pull rod, and the operation is relatively inconvenient.

[0033] In order to solve the problems in the related art to some extent, the embodiments of the present application provide a photoelectric switch protection device. When the photoelectric switch body 12 needs to be installed, first, the mounting plate at the top of the protective shell 11 is used to fix it at the desired position, then only the two knobs 24 need to be pinched, so that the knobs 24 slide in the sliding groove 23 and approach, at the same time, the vertical plate 21 is driven to approach and compress the spring 22. At the same time, the two vertical plates 21 approach and push the scissors arm 25 to stretch, pushing the push plate 26 out of the inside of the protective shell 11. At this time, the clamping plate 28 on one side of the photoelectric switch body 12 is slidably connected with the L-shaped plate 27, then the knobs 24 are released, and at the same time, the spring 22 rebounds to drive the vertical plate 21 to return to the original position, so that the scissors arm 25 contracts and pulls the push plate 26 back into the inside of the protective shell 11, at the same time, the photoelectric switch body 12 is also pulled back into the inside of the protective shell 11. The protective shell 11 can limit the L-shaped plate 27 and the clamping plate 28 to remain in the connected state and not to separate, avoiding the photoelectric switch body 12 from being separated from the inside of the protective shell 11, so that the installation of the photoelectric switch body 12 can be completed.

[0034] The present application will be described below in conjunction with the drawings and specific embodiments:

[0036] Specifically, the model of photoelectric switch body 12 is: Banner, the working principle is based on photoelectric effect, by transmitter emitting light, by receiver, to realize the detection of target object. Transmitter usually uses light emitting diode (LED), laser diode and other light sources, these light passes through lens or reflector and other optical elements, forms a parallel light or diffusion light, irradiates on the detected object. When the detected object enters the detection range of photoelectric switch, it will block or reflect part of light, resulting in the change of light intensity received by receiver. Receiver is usually a photosensitive element, such as photoresistor, photosensitive diode and the like, which can convert optical signal into electrical signal. After amplification, shaping and other processing, the electrical signal can drive the actuator to perform corresponding action, such as controlling motor start-stop, adjusting valve opening degree and the like.

[0037] Scissors arm 25 and push plate 26 are connected through sliding mechanism, and one end of the scissors arm 25 is slidably connected with one side of the push plate 26 when the scissors arm 25 stretches out or retracts.

[0038] When using, first, the installation plate on the top of the protection shell 11 is used to fix it at the required position, then only need to pinch two dial blocks 24, make the dial block 24 slide in the inside of the slide groove 23 and close, at the same time drive the vertical plate 21 to close and extrude the spring one 22 to compress, when two vertical plates 21 close, the scissors arm 25 will be pushed to stretch out, and the push plate 26 will be pushed out from the inside of the protection shell 11, then the clamp plate 28 on one side of the photoelectric switch body 12 is slidably connected with the L-shaped plate 27, then release the dial block 24, at the same time the spring one 22 rebounds to drive the vertical plate 21 to return to the original position, so that the scissors arm 25 retracts, the push plate 26 is pulled back to the inside of the protection shell 11, at the same time drive the photoelectric switch body 12 to retract into the inside of the protection shell 11, the protection shell 11 can limit the L-shaped plate 27 and the clamp plate 28 to keep the state of lapping and not separate, avoid the photoelectric switch body 12 from separating from the inside of the protection shell 11, that is, the installation of the photoelectric switch body 12 can be completed.

[0039] In some embodiments, the scissor arms 25 are symmetrically provided with two groups.

[0040] The use of two groups of scissor arms 25 can make the force on the push plate 26 more uniform when pushing the push plate 26 out of the inside of the protective shell 11.

[0047] In some embodiments, the connecting assembly 2 further comprises a plurality of convex strips 241 provided on one side of the knob 24.

[0048] The use of the convex strip 241 design can increase the friction when the knob 24 is pinched, making it less likely to slip during the pushing process.

[0049] In some embodiments, the L-shaped plate 27 is provided with a stabilizing assembly 3, which comprises a recess 31 opened in the outer side wall of the clamping plate 28; a plug rod 32 having one end penetrating the L-shaped plate 27, and the top end of the plug rod 32 being designed as a circular arc; a bottom plate 33 provided at one end of the plug rod 32; and a spring 34 sleeved outside the plug rod 32 and connected to the L-shaped plate 27 and the bottom plate 33 at both ends.

[0050] When the clamping plate 28 and the L-shaped plate 27 are slidably connected, the spring 34 rebounds to pull the bottom plate 33 and the L-shaped plate 27 close, causing the top end of the plug rod 32 to be inserted into the recess 31, thereby stabilizing the position of the clamping plate 28 and preventing the photoelectric switch body 12 from deviating when entering the inside of the protective shell 11.

[0051] In some embodiments, the stabilizing assembly 3 is provided with four groups symmetrically two by two.

[0052] The four-group design can improve the limiting effect when in use, thereby making the clamping plate 28 more stable.
