[0030] Referring to Figure 1 - Figure 2 , the present utility model provides a reflective marking device, which includes an upper housing 1, a lower housing 2 and a reflective component 3;

[0031] The upper housing 1 includes a top cover 10 and a side shell 11. The side shell 11 is arranged at the edge of the top cover 10 and encloses to form a hollow accommodation chamber. The reflective component 3 and the lower housing 2 are arranged in the accommodation chamber;

[0032] The lower housing 2 presses the reflective component 3 against the top cover 10, is connected to the side shell 11, and a through hole 13 is provided on the top cover 10. The through hole 13 is used to receive and reflect light on the reflective component 3.

[0033] In the above embodiment, the reflective marking device includes an upper housing 1, a lower housing 2 and a reflective component 3. The upper housing 1 includes a top cover 10 and a side shell 11 connected to the top cover 10. The side shell 11 is provided at the edge of the top cover 10 and extends along the entire circumferential direction of the edge of the top cover 10, so that a hollow accommodation chamber is formed by enclosing the top cover 10 and the side shell 11, ensuring that the reflective component 3 and the lower housing 2 can be placed in the accommodation chamber, and making the whole reflective marking device cylindrical. When the reflective component 3 is placed in the accommodation chamber, one end of the lower housing 2 abuts the reflective component 3 against the inner side of the top cover 10 located in the accommodation chamber, and a through hole 13 is provided in the top cover 10, and the through hole 13 is provided at the middle position of the top cover 10, so that the center of the through hole 13 and the center of the top cover 10 are the same circle. When the reflective component 3 needs to receive and reflect light, the light can contact the reflective component 3 through the through hole 13. In addition, the other end of the lower housing 2 far from the end for abutting the reflective component 3 is connected to the end of the side shell 11 far from the top cover 10. By wrapping the reflective component 3 with the upper housing 1 and the lower housing 2, the chance of direct contact with the outside is reduced, the physical wear caused by friction, impact, etc. is reduced, and the upper housing 1 and the lower housing 2 can block dust, moisture and other pollutants, reducing the possibility of the surface of the reflective component 3 being contaminated, keeping it clean, maintaining a high reflection efficiency, enabling the reflective component 3 to continuously maintain a high reflection ability, ensuring that the intensity of the reflection signal received by the optical locator is more stable, helping the optical locator to capture and analyze the reflected light more accurately, and thus improving the positioning accuracy.

[0034] Referring to Figure 1 - Figure 2 , in an embodiment, a first arc surface 14 is provided on the top cover 10, and the first arc surface 14 extends along the entire circumferential direction of the top cover 10, and the first arc surface 14 is gradually concave from the edge of the top cover 10 towards the through hole 13.

[0035] In the above embodiment, a first arc surface 14 is provided on the top cover 10. The first arc surface 14 is located between the edge of the through hole 13 and the edge of the top cover 10, and the first arc surface 14 extends along the entire circumferential direction of the top cover 10, so that the first arc surface 14 forms an annular structure on the top cover 10. At the same time, one end of the first arc surface 14 close to the side shell 11 is concave towards the end of the first arc surface 14 close to the edge of the through hole 13, that is, the first arc surface 14 is gradually concave from the edge of the top cover 10 towards the through hole 13. Therefore, when the reflective component 3 receives and reflects light through the through hole 13, the first arc surface 14 can more effectively focus the light, making the reflected light more concentrated, and the concave arc surface helps to reduce the scattering of light during the reflection process, making the reflected light more concentrated and directional, improving the clarity of the reflection signal, ensuring that the light can be closer to the normal direction during reflection, reducing the reflection loss, and improving the reflection efficiency.

[0036] Furthermore, the reflective component 3 is a reflective sheet or film with a planar structure, and its material is preferably polycarbonate, metal coating, polyvinyl chloride, etc. In addition, one end of the top cover 10 away from the first arc surface 14 is a planar structure for supporting the reflective component 3, so that one side of the top cover 10 is the first arc surface 14 and the other side is the support plane 17. When the reflective component 3 is attached to this plane, the periphery of the reflective component 3 is covered by the support plane 17, and the central part is used to receive and reflect light. Moreover, the diameter of the through hole 13 on the top cover 10 is greater than or equal to half of the diameter of the top cover 10 and less than or equal to four-thirds of the diameter of the top cover 10, maximizing the effective light receiving area, while avoiding light scattering caused by an overly large through hole 13, reducing unnecessary light scattering, and improving the directivity and clarity of the reflected light. Additionally, by arranging the reflective component 3 on the support plane 17, the support plane 17 provides a stable base for the reflective component 3, reducing displacement or deformation caused by vibration or impact, and ensuring that the reflective component 3 maintains high stability.

[0037] Refer to Figure 1 - Figure 2 , in an embodiment, a plurality of spaced grooves 15 are provided at one end of the side shell 11 away from the top cover 10, and at least one clamping component 16 for clamping the lower shell 2 is provided in the grooves 15.

[0038] In the above embodiment, a plurality of grooves 15 are provided on the side shell 11, and the grooves 15 are located at one end of the side shell 11 away from the top cover 10 and extend towards the top cover 10. The extending depth is less than half of the height of the entire side shell 11. The plurality of grooves 15 are evenly arranged on the side shell 11 at a specified interval, and the grooves 15 are preferably U-shaped grooves. In addition, at least one clamping component 16 is provided in the grooves 15, and the clamping component 16 is connected to the middle position of the grooves 15, forming a specified gap between the clamping component 16 and both sides of the grooves 15. The stress between the clamping component 16 and the grooves 15 can be dispersed through the gap, reducing fatigue or damage of the clamping component 16 caused by stress concentration, and making the clamping component 16 have a certain elasticity. The clamping component 16 is more likely to be clamped with the lower shell 2, reducing the force required during assembly. The clamping component 16 is used for snap-connecting the lower shell 2. By snap-connecting the upper shell 1 to the lower shell 2, the installation of the upper shell 1 and the lower shell 2 is easy to operate, rapid installation and disassembly can be achieved, the assembly efficiency is improved, and snap-connection usually does not require additional tools, facilitating on-site rapid assembly and maintenance.

[0039] Refer to Figure 1 - Figure 2, in one embodiment, the clamping component 16 includes a clamping body 160 and a clamping portion 161. The clamping body 160 is connected to the side shell 11. The clamping portion 161 is disposed at one end of the clamping body 160 away from the side shell 11 and extends in a direction close to the accommodating chamber.

[0040] In the above embodiment, the clamping component 16 includes a clamping body 160 and a clamping portion 161 connected to the clamping body 160. The clamping body 160 is connected to the side shell 11, and the height of the clamping body 160 is the same as the depth of the sinking groove 15, so that the top surface of the clamping body 160 and one end surface of the side shell 11 away from the top cover 10 are on the same horizontal plane. One end surface of the clamping body 160 close to the accommodating chamber and the inner wall of the side shell 11 are on the same arc surface. A specified gap is formed between one end surface of the clamping body 160 away from the accommodating chamber and the outer wall of the side shell 11, so that the thickness of the entire clamping body 160 is smaller than the thickness of the side shell 11. The clamping portion 161 is disposed at one end of the clamping body 160 away from the side shell 11, and the clamping portion 161 extends in a direction close to the accommodating chamber, so that the clamping portion 161 protrudes from one end surface of the clamping body 160 close to the accommodating chamber. At the same time, the clamping body 160, the clamping portion 161, the side shell 11 and the top cover 10 are integral parts, so that the clamping portion 161 can better withstand external forces when clamping the lower shell 2, reduce damage caused by improper engagement, and improve the overall strength of the upper shell 1.

[0041] Referring to Figure 1 - Figure 2 , in one embodiment, the lower shell 2 includes a resisting top portion 20 and a connecting portion 21. The connecting portion 21 is disposed at one end of the resisting top portion 20 away from the reflecting component 3, and a clamping platform 22 is disposed at the connection between the resisting top portion 20 and the connecting portion 21. The clamping portion 161 is clamped on the clamping platform 22.

[0042] In the above embodiment, the lower housing 2 includes an abutting top portion 20 and a connecting portion 21 connected to the abutting top portion 20. The connecting portion 21 is provided at an end of the abutting top portion 20 away from the reflecting member 3, and the diameter of the connecting portion 21 is smaller than that of the abutting top portion 20, so that a clamping platform 22 is formed at the connection between the abutting top portion 20 and the connecting portion 21, and the clamping platform 22 extends along the entire circumferential direction of the abutting top portion 20. The width of the clamping platform 22 is greater than or equal to the width of the clamping portion 161, and the overall height of the clamping member 16 is greater than or equal to the height of the entire lower housing 2. When the clamping portion 161 is clamped on the clamping platform 22, the circumferential extension and sufficient width of the clamping platform 22 provide a larger contact area, increasing the friction between the clamping member 16 and the lower housing 2, making the connection more stable. The clamping member 16 can be stably and firmly connected to the lower housing 2, and the clamping platform 22 provides a clear assembly interface, simplifying the assembly process of the clamping portion 161 and the lower housing 2 and reducing the assembly time.

[0043] Referring to Figure 1 - Figure 2 , in one embodiment, a plugging groove 23 is provided in the connecting portion 21, and a plugging post 24 connected to the connecting portion 21 is provided in the plugging groove 23 for connecting a rigid tool.

[0044] In the above embodiment, a plugging groove 23 is provided inside the connecting portion 21, and the plugging groove 23 extends towards the abutting top portion 20 so as to penetrate the entire connecting portion 21 and part of the abutting top portion 20. In addition, a plugging post 24 is provided in the plugging groove 23. The plugging post 24 is located at the middle position of the plugging groove 23, and its bottom is connected to the bottom wall of the plugging groove 23. A certain distance is formed between the side wall of the plugging post 24 and the side wall of the plugging groove 23, so that the side wall of the plugging post 24 is connected to the side wall of the plugging groove 23 through a plurality of connecting plates. The plugging post 24 is mainly used to connect an external rigid tool. The plugging post 24 provides accurate positioning points to ensure the alignment and stability between the rigid tool and the entire reflecting marking device. The plugging post 24 adds additional connection points, making the connection between the rigid tool and the reflecting marking device more firm.

[0045] Referring to Figure 1 - Figure 2 , in one embodiment, a second arc surface 162 is provided at an end of the clamping portion 161 away from the clamping body 160, and the second arc surface 162 is gradually concave from the top to the bottom of the clamping portion 161.

[0046] In the above embodiment, a second arc surface 162 is provided on the top surface of the end of the buckle portion 161 away from the buckling body 160. The second arc surface 162 extends along the entire length direction of the buckle portion 161, and the second arc surface 162 gradually concaves from the top of the buckle portion 161 towards the bottom of the buckle portion 161. The concave second arc surface 162 can more closely fit the surface when the upper shell 1 is buckled, providing a larger contact area, thereby enhancing the buckling force. At the same time, the concave second arc surface 162 makes it easier for the buckle portion 161 to be inserted into the upper shell 1, reducing the friction and resistance during the insertion process, simplifying the buckling process, and helping to improve the assembly speed and efficiency.

[0047] Referring to Figure 1 - Figure 2 , in an embodiment, a third arc surface 25 corresponding to the second arc surface is formed on the side wall of the end of the abutting top portion 20 away from the connecting portion 21. The third arc surface 25 extends along the entire circumferential direction of the abutting top portion 20, and the third arc surface 25 gradually concaves from the periphery of the abutting top portion 20 towards the center.

[0048] In the above embodiment, a third arc surface 25 is provided on the side wall of the abutting top portion 20. The third arc surface 25 is located at the end of the abutting top portion 20 away from the connecting portion 21, making it located at the end close to the reflective component 3, and the third arc surface 25 is arranged corresponding to the second arc surface 162. The third arc surface 25 extends along the entire circumferential direction of the abutting top portion 20, and the third arc surface 25 gradually concaves from the periphery of the side wall of the abutting top portion 20 towards the center of the abutting top portion 20. When the lower shell 2 is installed in the accommodation chamber of the upper shell 1, the third arc surface 25 on the abutting top portion 20 first contacts the second arc surface 162 of the buckle portion 161. Through the mutual cooperation of the second arc surface 162 and the third arc surface 25, the resistance at the initial stage of buckling of the lower shell 2 is reduced, allowing a progressive fitting process between the lower shell 2 and the upper shell 1, improving the buckling accuracy, and through the sliding cooperation of the second arc surface 162 and the third arc surface 25, the force required to install the lower shell 2 into the upper shell 1 is reduced, facilitating manual or automated assembly and improving the overall assembly efficiency.
