[0025] Example

[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides a light-shielding structure for a light receiver during position adjustment, including:

[0027] The adjustment assembly 100 includes a base plate 101, a sliding plate 102 slidably mounted in the middle of the base plate 101, a support plate 103 slidably connected to the upper end of the sliding plate 102, and a fixing plate 104 inserted into the upper end of the support plate 103.

[0028] The optical receiver assembly 200 includes an optical receiver body 201 snapped into the middle of the fixing plate 104, an adapter ring 202 fixedly connected to the end of the optical receiver body 201, a light-shielding sleeve 203 threadedly connected to the end of the adapter ring 202, and a sealing ring 204 adapted to be installed at the end of the light-shielding sleeve 203. The end of the sealing ring 204 extends to the side wall of the adapter ring 202, and the sealing ring 204 is sleeved on the outside of the optical receiver body 201.

[0029] The sliding plate 102 can slide in the middle of the base plate 101, allowing the optical receiver to be adjusted horizontally. The support plate 103 is slidably connected to the upper end of the sliding plate 102, allowing the support plate 103 to move vertically relative to the sliding plate 102, thus changing its height. The fixing plate 104 is inserted into the upper end of the support plate 103, providing an installation position for the optical receiver assembly 200. The optical receiver assembly 200 is the part that realizes the light receiving function and has light-shielding characteristics. The optical receiver body 201 is snapped into the middle of the fixing plate 104 and is the core component of the light receiver. The adapter ring 202 is fixed to the end of the optical receiver body 201, providing a connection interface for the installation of subsequent components. The light-shielding sleeve 203 is installed at the end of the adapter ring 202 via a threaded connection. Its main function is to block stray light from the surrounding environment and prevent it from interfering with the optical receiver body 201's reception of the required optical signal. The sealing ring 204 is fitted and installed at the end of the light-shielding sleeve 203. It extends to the side wall of the adapter ring 202 and is sleeved on the outside of the optical receiver body 201. On the one hand, it can provide a certain degree of protection for the optical receiver body 201. On the other hand, it can fit tightly with the light-shielding sleeve 203 and the adapter ring 202 to enhance the sealing of the light-shielding structure, prevent light from entering from the gaps at the connection, and ensure that the optical signal received by the optical receiver body 201 is as unaffected as possible by external light, thus ensuring the accuracy and reliability of the received optical signal.

[0030] Specifically, the outer side wall of the sealing ring 204 is provided with a stepped edge structure, and the stepped edge of the side wall of the sealing ring 204 is used in conjunction with the side wall of the light-shielding sleeve 203.

[0031] The sealing ring 204 is adapted to be installed at the end of the light-shielding sleeve 203 and extends to the side wall of the adapter ring 202. It is sleeved on the outside of the light receiver body 201. Its end outer side wall has a stepped edge structure to prevent the sealing ring 204 from being screwed into the light-shielding sleeve 203.

[0032] Furthermore, the end of the sealing ring 204 contacts the side wall of the adapter ring 202, and the sealing ring 204 is sleeved on the outside of the adapter ring 202.

[0033] The sealing ring 204 has its end in contact with the side wall of the adapter ring 202 and is fitted onto the outside of the adapter ring 202. This enhances the sealing performance of the light-shielding structure, prevents light from entering through gaps, and ensures that the light signal received by the light receiver is purer.

[0034] Furthermore, the adjustment assembly 100 also includes a pressure block 105 fixedly connected to the top of the fixing plate 104, and the pressure block 105 is snapped onto the outside of the optical receiver body 201.

[0035] The pressure block 105 is used to limit the position of the optical receiver body 201, prevent the optical receiver body 201 from loosening, and maintain the stability of the position of the optical receiver body 201.

[0036] Preferably, the adjustment assembly 100 further includes a first knob 106 rotatably mounted on the side wall of the sliding plate 102, the end of the first knob 106 being threadedly connected to the side wall of the support plate 103.

[0037] The first knob 106 is rotatably mounted on the side wall of the sliding plate 102, and its end is threadedly connected to the side wall of the support plate 103. When the first knob 106 is rotated, the support plate 103 will move up and down along the sliding plate 102 due to the transmission action of the thread, thereby achieving fine adjustment of the vertical position.

[0038] It should be noted that the adjustment assembly 100 also includes a second knob 107 threadedly connected to the side wall of the support plate 103, and the end of the second knob 107 is inserted into the through hole in the side wall of the fixing plate 104.

[0039] The second knob 107 is threaded to the side wall of the support plate 103, and its end is inserted into the through hole in the side wall of the fixing plate 104. By rotating the second knob 107, the position of the fixing plate 104 relative to the support plate 103 can be adjusted to further precisely control the position of the optical receiver.

[0040] Preferably, the adjustment assembly 100 further includes a limiting plate 108 installed at the end of the support plate 103, and a limiting post 109 inserted in the middle of the limiting plate 108, with the end of the limiting post 109 fixedly connected to the side wall of the sliding plate 102.

[0041] The limiting plate 108 is installed at the end of the support plate 103, and the limiting post 109 is inserted into the middle of the limiting plate 108 and its end is fixedly connected to the side wall of the sliding plate 102. The cooperation between the limiting post 109 and the limiting plate 108 can limit the movement range of the support plate 103 and ensure the stability and safety of the position adjustment.

[0042] In use, this light-shielding structure mainly consists of an adjustment component 100 and a light receiver component 200. The adjustment component 100 provides support and adjustment means for the position adjustment of the light receiver. A base plate 101 serves as the foundation, and a sliding plate 102 can slide in the middle of the base plate 101. Through this sliding movement, the position of the light receiver in the horizontal direction can be adjusted. A support plate 103 is slidably connected to the upper end of the sliding plate 102, providing the light receiver with vertical position adjustment capability. A fixing plate 104 is inserted into the upper end of the support plate 103 to fix the light receiver component 200. A first knob 106 is rotatably mounted on the sliding plate 102. The sidewall, with its end threadedly connected to the sidewall of the support plate 103, allows for fine-tuning of the vertical position by rotating the first knob 106, which, due to the transmission action of the thread, pushes the support plate 103 up and down along the sliding plate 102. The second knob 107 is threadedly connected to the sidewall of the support plate 103, with its end inserted into a through hole in the sidewall of the fixing plate 104. By rotating the second knob 107, the position of the fixing plate 104 relative to the support plate 103 can be adjusted, further precisely controlling the position of the light receiver. The limiting plate 108 is installed at the end of the support plate 103, and the limiting post 109 is inserted into the middle of the limiting plate 108 with its end fixedly connected to the sidewall. The sidewall of the sliding plate 102, the cooperation of the limiting post 109 and the limiting plate 108, can limit the movement range of the support plate 103, ensuring the stability and safety of position adjustment. The light receiver assembly 200 is the part that realizes the functions of light reception and light shielding. The light receiver body 201 is snapped into the middle position of the fixed plate 104, the adapter ring 202 is fixed to the end of the light receiver body 201, and the light shielding sleeve 203 is threaded to the end of the adapter ring 202. The light shielding sleeve 203 plays the role of light shielding to prevent external light from interfering with the light receiver body 201 to receive the required light signal. The sealing pressure ring 204 is adapted to be installed on the end of the light shielding sleeve 203. The light-shielding sleeve 203 is fitted onto the outer side of the light receiver body 201, and extends to the side wall of the adapter ring 202. The outer side wall of the adapter ring 204 has a stepped edge structure, which cooperates with the side wall of the light-shielding sleeve 203. At the same time, the end of the sealing pressure ring 204 contacts the side wall of the adapter ring 202 and is fitted onto the outer side of the adapter ring 202, which enhances the sealing performance of the light-shielding structure, prevents light from entering from the gap, and ensures that the light signal received by the light receiver is purer. The pressure block 105 is fixed to the top of the fixing plate 104 and snapped onto the outer side of the light receiver body 201, which can fix and protect the light receiver body 201 and ensure its stability during position adjustment.

[0043] In summary, by adjusting the sliding plate 102, support plate 103, and the first knob 106 and second knob 107 in component 100, the position of the optical receiver can be precisely adjusted in both horizontal and vertical directions. This allows for convenient adjustment of the optical receiver's position according to different working requirements, ensuring the optical receiver is in the optimal receiving position and improving the accuracy and efficiency of light reception. The light-shielding sleeve 203 and sealing ring 204 effectively block external light interference. Simultaneously, the stepped edge structure of the sealing ring 204 and its cooperation with the adapter ring 202 ensure the airtightness of the light-shielding structure, preventing stray light from entering the optical receiver and guaranteeing the signal received by the optical receiver. The signal quality is improved, enhancing signal reliability and accuracy. The clamping block 105 secures the optical receiver body 201, ensuring stability during position adjustment and operation, preventing displacement or shaking, and guaranteeing stable optical reception. The limiting structure of the limiting post 109 and the limiting plate 108 ensures the safety and reliability of the position adjustment process, preventing damage to components or displacement of the optical receiver due to over-adjustment. Position adjustment is performed using a knob, which is simple and convenient to operate. By rotating the knob, operators can easily fine-tune the position of the optical receiver without the need for complex operations and tools, reducing operational difficulty and improving work efficiency.
