Description

Technical Field

[0001] This utility model belongs to the field of photoelectric sensor technology, and specifically relates to a photoelectric sensor mechanism with a protective structure. Background Technology

[0002] As a key sensing element in modern industrial automation, environmental monitoring, and safety protection, photoelectric sensors detect the presence, location, or characteristics of target objects through light signals. They have advantages such as fast response, high accuracy, and non-contact operation. However, in industrial production, outdoor environments, or special scenarios (such as mines, chemical plants, and food processing plants), sensors are often exposed to complex conditions such as dust, water vapor, oil, mechanical vibration, or extreme temperature and humidity. The stability and lifespan of traditional photoelectric sensors face severe challenges.

[0003] In the prior art, the protection of photoelectric sensors mostly adopts a single method, which is to add a metal shell to resist mechanical impact. The metal shell is mostly a fixed design, which requires complete disassembly for maintenance, which is cumbersome and increases downtime costs. Therefore, this utility model provides a photoelectric sensor mechanism with a protective structure. Utility Model Content

[0004] The purpose of this invention is to provide a photoelectric sensor mechanism with a protective structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photoelectric sensor mechanism with a protective structure, comprising a photoelectric sensor body, a cylindrical transmitter and receiver respectively provided on both sides of the photoelectric sensor body, two connectors provided on the top of the photoelectric sensor body, a protective component provided between the connectors, a threaded connecting post provided at the bottom of the photoelectric sensor body, and the protective component comprising two fixed inclined plates connected to the connectors.

[0006] In a preferred embodiment, the two connectors are arranged in a figure-eight shape, and a limiting groove is formed on the opposite surface of the two connectors, the limiting groove being adapted to the fixing inclined plate.

[0007] In a preferred embodiment, a fixing button is provided on the mating surface of the fixing inclined plate and the connector, a mating hole adapted to the fixing button is provided on the mating surface of the connector and the fixing inclined plate, and a deformation cavity is provided inside the connector.

[0008] In a preferred embodiment, the protective assembly has protective inclined plates on both sides, and each of the protective inclined plates has an arc-shaped groove at its bottom end, with the two arc-shaped grooves respectively fitting against the top of the transmitter and the receiver.

[0009] In a preferred embodiment, each of the protective inclined plates is provided with an arc-shaped support plate at the bottom of the connection between the protective inclined plate and the protective component. The bottom end of the arc-shaped support plate is provided with an adhesive plate, and one side and the bottom of the adhesive plate are respectively attached to the inclined surface of the connector and the top of the photoelectric sensor body.

[0010] In a preferred embodiment, the protective assembly is provided with side shields on both other sides, the bottom of the side shields is semi-circular, and the bottom of the side shields contacts the top of the photoelectric sensor body.

[0011] In a preferred embodiment, the top of the photoelectric sensor body is provided with a heat dissipation channel, and the center of the protective component is provided with a heat dissipation hole, which is located directly above the heat dissipation channel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The photoelectric sensor mechanism with protective structure has a fixed inclined plate connected to the mating hole on the connector through a fixing button, and elastically fixed by means of deformation cavity. This design allows the protective component to be easily disassembled and installed without disassembling the entire photoelectric sensor mechanism, which greatly simplifies the maintenance process and reduces downtime costs.

[0014] This photoelectric sensor mechanism with a protective structure, through its designed protective components including a fixed inclined plate, a protective inclined plate, an arc-shaped support plate, a bonding plate, and a side protective plate, can protect the photoelectric sensor body and its key components from environmental factors such as dust, water vapor, and oil stains in all directions, while also providing a certain degree of mechanical vibration protection, thereby improving the stability and service life of the sensor under complex working conditions.

[0015] This photoelectric sensor mechanism with a protective structure ensures that the main body of the photoelectric sensor can effectively dissipate heat during operation through the heat dissipation channels and heat dissipation holes, avoiding the impact of overheating on performance and lifespan. This is especially important for sensors that work in sealed or high-temperature environments. Attached Figure Description

[0021] The present invention will be further described below with reference to the embodiments.

[0022] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] Please see Figure 1-4This utility model provides a photoelectric sensor mechanism with a protective structure, including a photoelectric sensor body 1. A cylindrical transmitter 102 and a receiver 103 are respectively provided on both sides of the photoelectric sensor body 1. Two connectors 105 are provided at the top of the photoelectric sensor body 1, and a protective component 2 is provided between the connectors 105. A threaded connecting post 101 is provided at the bottom of the photoelectric sensor body 1. The protective component 2 includes two fixed inclined plates 202 connected to the connectors 105. The two connectors 105 are arranged in a V-shape. Limiting grooves 1053 are provided on the opposite surfaces of the connector 105. The limiting grooves 1053 are adapted to the fixing inclined plate 202. A fixing button 203 is provided on the mating surface of the fixing inclined plate 202 and the connector 105. A mating hole 1051 adapted to the fixing button 203 is provided on the mating surface of the connector 105 and the fixing inclined plate 202. A deformation cavity 1052 is provided inside the connector 105. The photoelectric sensor body 1 is fixed to the required position by the threaded connecting post 101 at its bottom. The two connectors 105 are distributed in a figure-eight shape on the photoelectric sensor body 105. On the top of the sensor body 1, and ensuring a secure connection, align the two fixing inclined plates 202 of the protective assembly 2 with the limiting grooves 1053 on the connector 105, and gently push them in until the fixing inclined plates 202 are fully embedded in the limiting grooves 1053. Use the fixing button 203, passing through the pre-drilled hole on the fixing inclined plate 202, to align it with the mating hole 1051 on the connector 105, so that the fixing button 203 is firmly fixed to the connector 105. Since the connector 105 has a deformation cavity 1052 inside, the fixing button 203 will tighten... When pressed, the wall of the deformation cavity 1052 is slightly compressed, thereby providing additional fixing force and stability. When the photoelectric sensor body 1 is powered on, the transmitter 102 emits a light signal, which is received by the receiver 103, thereby realizing the detection of the target object. The presence of the protective component 2 ensures that the photoelectric sensor body 1 is not affected by the external environment. If the sensor needs maintenance or replacement, simply loosen the fixing button 203 and remove the fixing inclined plate 202 from the limiting groove 1053 to easily access the photoelectric sensor body 1.

[0024] The design of the protective component 2 effectively protects the photoelectric sensor body 1 from external environmental damage, improving the stability and service life of the sensor. The tight fit between the fixing plate 202 and the connector 105, as well as the reinforcement effect of the fixing button 203, ensures the stability of the protective component 2. With the simple design of the fixing button 203, users can easily install and remove the protective component 2 without using complicated tools or performing cumbersome operations. This design not only improves maintenance efficiency but also reduces downtime costs.

[0025] In this embodiment, protective inclined plates 204 are provided on both sides of the protective component 2. Each protective inclined plate 204 has an arc-shaped groove 205 at its bottom end. The two arc-shaped grooves 205 are respectively fitted to the top of the transmitter 102 and the receiver 103. An arc-shaped support plate 206 is provided at the bottom of the connection point between each protective inclined plate 204 and the protective component 2. An adhesive plate 207 is provided at the bottom end of the arc-shaped support plate 206. One side and the bottom of the adhesive plate 207 are respectively fitted to the inclined surface of the connector 105 and the top of the photoelectric sensor body 1. Side protective plates 208 are provided on the other two sides of the protective component 2. The bottom end of the side protective plate 208 is semi-circular, and the bottom end of the side protective plate 208 is... The top of the photoelectric sensor body 1 is in contact with the protective inclined plate 204, which is precisely aligned and attached to the top of the transmitter 102 and receiver 103 through the arc groove 205 at its bottom end, ensuring that these critical components are fully protected. The arc support plate 206 is located between the protective inclined plate 204 and the connector 105, providing additional support and stability. The bonding plate 207 is tightly attached to the inclined surface of the connector 105 and the top of the photoelectric sensor body 1, further consolidating the entire protective structure. The side protective plates 208 are installed on the other two sides of the protective assembly 2, and their semi-circular bottom ends contact the top of the photoelectric sensor body 1, forming an additional protective barrier.

[0026] During sensor operation, the protective inclined plate 204, arc-shaped support plate 206, bonding plate 207, and side guard plate 208 work together to resist external impacts. These protective components can also reduce the impact of mechanical vibration on the sensor to a certain extent, improving the sensor's stability and reliability. By adding components such as the protective inclined plate 204, arc-shaped support plate 206, bonding plate 207, and side guard plate 208, this embodiment provides more comprehensive and detailed protection for the photoelectric sensor body 1 and its key components. The synergistic effect of these components effectively blocks external contaminants from damaging the sensor, extending the sensor's service life. The addition of the arc-shaped support plate 206 and bonding plate 207 not only provides additional support but also enhances the connection strength between the protective component 2 and the photoelectric sensor body 1. This helps prevent the protective component 2 from loosening or falling off under harsh working conditions, ensuring the sensor's continuous and stable operation.

[0027] In this embodiment, a heat dissipation channel 104 is provided at the top of the photoelectric sensor body 1, and a heat dissipation hole 201 is provided at the center of the protective component 2. The heat dissipation hole 201 is located directly above the heat dissipation channel 104. When the photoelectric sensor body 1 starts to work, its internal electronic components will generate heat. This heat will be conducted upward through the heat dissipation channel 104 to find a heat dissipation path. The heat dissipation channel 104 guides the heat to the top of the photoelectric sensor body 1. At this time, the heat dissipation hole 201 in the protective component 2 acts as a "window" for heat to dissipate, allowing heat to escape from the inside of the sensor to the surrounding environment. The escaped heat exchanges with the surrounding environment and is gradually absorbed and dispersed by the environment. This process helps to reduce the internal temperature of the photoelectric sensor body 1 and prevent performance degradation or damage caused by overheating.

[0028] The working principle and usage process of this utility model are as follows: First, fix the photoelectric sensor body 1 to the desired position through the threaded connecting post 101 at its bottom. Arrange the two connecting pieces 105 in a figure-eight pattern on the top of the photoelectric sensor body 1, ensuring they are securely connected. Align the two fixing inclined plates 202 of the protective assembly 2 with the limiting grooves 1053 on the connecting pieces 105, and gently push them in until the fixing inclined plates 202 are fully embedded in the limiting grooves 1053. Then, use the fixing button 203, passing through the pre-drilled hole on the fixing inclined plate 202, to connect with the connecting piece... The mating holes 1051 on connector 105 are aligned, allowing the fixing button 203 to be securely fixed to connector 105. Since connector 105 has a deformation cavity 1052 inside, the fixing button 203 slightly compresses the wall of the deformation cavity 1052 when tightened or pressed, thus providing additional fixing force and stability. When the photoelectric sensor body 1 is powered on, transmitter 102 emits a light signal, which is received by receiver 103, thereby enabling the detection of the target object. The presence of protective component 2 ensures that the photoelectric sensor body 1 is not affected by the external environment. To prevent interference, if the sensor needs maintenance or replacement, simply loosen the fixing button 203 and remove the fixing ramp 202 from the limiting groove 1053 to easily access the photoelectric sensor body 1. During sensor operation, the protective ramp 204, arc-shaped support plate 206, bonding plate 207, and side guard plate 208 work together to resist external impacts. These protective components can also reduce the impact of mechanical vibration on the sensor to a certain extent, improving the stability and reliability of the sensor. By adding components such as the protective ramp 204, arc-shaped support plate 206, bonding plate 207, and side guard plate 208, this embodiment provides more comprehensive and detailed protection for the photoelectric sensor body 1 and its key components. The synergistic effect of these components effectively blocks external contaminants from damaging the sensor and extends the sensor's service life. The addition of the arc-shaped support plate 206 and bonding plate 207 not only provides additional support but also enhances the connection strength between the protective component 2 and the photoelectric sensor body 1. This helps prevent the protective component 2 from loosening or falling off under harsh working conditions, ensuring the continuous and stable operation of the sensor.
