Abstract
Description
Technical Field
[0001] This utility model relates to the field of photoelectric switch technology, and in particular to a photoelectric switch with a buffer function. Background Technology
[0002] A photoelectric switch is a device that detects the presence or absence of an object by utilizing the principle of the object blocking or reflecting a light beam, and connecting the circuit through a synchronous loop. This device can rapidly detect and control the state and movement of various substances (such as solids, liquids, and transparent bodies) in a non-contact and non-destructive manner.
[0003] Existing photoelectric switches lack a dedicated buffer structure. When subjected to external vibration or impact, the internal components of the photoelectric switch are directly impacted. The vibration and impact may cause the sensor or photoelectric device of the photoelectric switch to undergo slight displacement, thereby affecting its detection accuracy and sensitivity. Utility Model Content
[0004] The purpose of this invention is to provide a photoelectric switch with a buffer function. This device facilitates the buffer protection of the photoelectric switch, thus solving the problem that the existing technology does not facilitate the buffer protection of photoelectric switches.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A photoelectric switch with a buffer function includes a housing, wherein multiple air bladders are arranged in a ring array on the inner wall of the housing, and multiple holes are arranged in a ring array through the side wall of the housing. A photoelectric switch is disposed inside the housing, and the side wall of the photoelectric switch is attached to the side wall of the air bladder. A side cover is threaded on one side of the housing and a transparent plate is disposed inside the side cover. A cover plate is threaded on the other side of the housing and an elastic pad is disposed inside the cover plate.
[0007] Preferably, a cavity is provided inside the side wall of the housing, and a plurality of connecting grooves are provided on the inner wall of the housing. The plurality of connecting grooves are arranged in a circular array, and the connecting grooves are in communication with the cavity.
[0008] Preferably, the sidewall of the airbag is provided with a groove, and the groove communicates with the connecting groove.
[0009] Preferably, a pipe is fixedly connected through one side of the housing, and a valve is installed inside the pipe, which is in communication with the cavity.
[0010] Preferably, the side cover has a through groove through its side wall, and the inner wall of the through groove is threadedly connected to the side wall of the transparent plate, which is made of plastic.
[0011] Preferably, the side wall of the cover plate is provided with a through hole, the inner wall of the through hole is fixedly connected to the side wall of the elastic pad, and the side wall of the elastic pad is provided with a through hole.
[0012] Compared with the prior art, the advantages of this utility model are:
[0013] 1. Gas is delivered into the cavity through pipes. Multiple connecting slots are used to guide the airflow from inside the cavity. The gas drawn from the connecting slots flows into the airbags through the slot openings, inflating the airbags and causing them to fit tightly against the side wall of the photoelectric switch, thus wrapping and securing the photoelectric switch. At the same time, the inflation volume inside the airbags can be adjusted according to the size of the photoelectric switch, thereby wrapping and securing photoelectric switches of different sizes, improving the versatility and flexibility of the device, and forming a wrap-around protective layer. When the shell is vibrated, the multiple airbags can respond quickly, providing all-round buffering and shock absorption protection for the photoelectric switch, reducing the risk of damage to the photoelectric switch during collisions.
[0014] 2. Install the side cover threaded onto one side of the housing, and then install the cover plate threaded onto the other side of the housing. At the same time, the connecting wire of the photoelectric switch slides through the slot. Due to the elasticity of the elastic pad, the slot can be freely contracted and relaxed according to the thickness of the connecting wire. When the photoelectric switch is in operation, the light emitted by the photoelectric switch passes through the transparent plate and shines on the object being detected. At the same time, through the multiple holes, the heat generated by the photoelectric switch during operation can flow into the housing, preventing the photoelectric switch from being damaged due to overheating, thereby extending the service life of the photoelectric switch.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figure 1-5 A photoelectric switch with a buffer function includes a housing 001, with multiple airbags 103 arranged in a ring array on the inner wall of the housing 001, and multiple holes 106 arranged in a ring array through the side wall of the housing 001. A photoelectric switch 107 is disposed inside the housing 001, with the side wall of the photoelectric switch 107 fitting against the side wall of the airbags 103. A side cover 002 is threaded onto one side of the housing 001, and a transparent plate 202 is disposed inside the side cover 002. A cover plate 003 is threaded onto the other side of the housing 001, and an elastic pad 302 is disposed inside the cover plate 003. An operator places the photoelectric switch 107 inside the housing 001 and then inflates the multiple airbags 103, causing them to fit tightly against the side wall of the photoelectric switch 107, thus forming a protective layer that buffers the airbags. The cover 002 is threaded onto one side of the housing 001. The transparent plate 202 inside the cover 002 ensures that the light emitted by the photoelectric switch 107 can pass through smoothly. The cover plate 003 is then threaded onto the other side of the housing 001. At the same time, the connecting wire of the photoelectric switch 107 passes through the elastic pad 302. When the photoelectric switch 107 is in operation, the light emitted by the photoelectric switch 107 passes through the transparent plate 202 and shines on the object being detected. At the same time, through the multiple holes 106, the heat generated by the photoelectric switch 107 during operation can flow into the housing 001, thereby preventing the photoelectric switch 107 from being damaged due to overheating. When the housing 001 is vibrated, the multiple airbags 103 can respond quickly to provide all-round buffering and shock absorption protection for the photoelectric switch 107. The multiple holes 106 are distributed on both sides of the cavity 101.
[0023] The housing 001 has a cavity 101 inside its side wall, and a plurality of connecting grooves 102 are provided on the inner wall of the housing 001. The plurality of connecting grooves 102 are arranged in a circular array and are connected to the cavity 101. The airflow flowing inside the cavity 101 is discharged by providing the plurality of connecting grooves 102.
[0024] The side wall of the airbag 103 is provided with a slot 104, which is connected to the connecting slot 102. The gas discharged from the connecting slot 102 flows into the airbag 103 through the slot 104, thereby inflating the airbag 103.
[0025] A pipe 105 is fixedly connected through one side of the housing 001. A valve is installed inside the pipe 105. The pipe 105 is connected to the cavity 101. When the valve inside the pipe 105 is opened, gas is transported through the pipe 105 to the cavity 101.
[0026] The side cover 002 has a through groove 201 through its side wall. The inner wall of the through groove 201 is threaded to the side wall of the transparent plate 202. The transparent plate 202 is made of plastic. The through groove 201 limits the installation position of the transparent plate 202.
[0027] A slot 301 is provided through the side wall of the cover plate 003. The inner wall of the slot 301 is fixedly connected to the side wall of the elastic pad 302. A slot 303 is provided through the side wall of the elastic pad 302. The connecting wire of the photoelectric switch 107 slides through the slot 303. Due to the elasticity of the elastic pad 302, the slot 303 can be freely contracted and relaxed depending on the thickness of the connecting wire.
[0028] In this invention, the operator places the photoelectric switch 107 inside the housing 001, opens the valve inside the pipe 105, and delivers gas through the pipe 105 into the cavity 101. Multiple connecting grooves 102 are used to guide the airflow inside the cavity 101. The gas discharged from the connecting grooves 102 flows through the slots 104 into the airbags 103, thereby inflating the airbags 103 and causing them to fit tightly against the side wall of the photoelectric switch 107, thus wrapping and fixing the photoelectric switch 107 and forming a protective layer. When the housing 001 is vibrated, the multiple airbags 103 can respond quickly, providing all-round buffering and shock absorption protection for the photoelectric switch 107.
[0029] After the photoelectric switch 107 is fixed, the side cover 002 is threaded onto one side of the housing 001, and the cover plate 003 is threaded onto the other side of the housing 001. At the same time, the connecting wire of the photoelectric switch 107 slides through the slot 303. Due to the elasticity of the elastic pad 302, the slot 303 can be freely contracted and relaxed according to the thickness of the connecting wire. When the photoelectric switch 107 is in operation, the light emitted by the photoelectric switch 107 passes through the transparent plate 202 and shines on the object being detected. At the same time, through the multiple holes 106, the heat generated by the photoelectric switch 107 during operation can flow into the interior of the housing 001 to prevent the photoelectric switch 107 from being damaged due to overheating.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
