Description

Technical Field

[0001] This utility model relates to the field of light guide technology, specifically a plastic composite light guide. Background Technology

[0002] A plastic composite light guide is not a type of plastic composite light guide "wire," but rather a plastic composite material with special functions used to guide and control the propagation of light. A plastic composite light guide utilizes plastic as its base material and, through the addition of specific light-guiding components or the adoption of special structural designs, can effectively guide the propagation of light within it.

[0003] In existing technologies, plastic composite light guides are generally composed of a polymer matrix and light-guiding microparticles or fibers. The polymer matrix provides the material with mechanical strength and flexibility, while the light-guiding microparticles or fibers are responsible for guiding light into the interior of the material and propagating it along a specific path. When light shines on the input end of the plastic composite light guide, it can efficiently enter the interior of the light guide through a special surface structure or optical coupling mechanism. Inside the light guide, due to the special optical properties of the polymer matrix and the light-guiding microparticles or fibers, the light will propagate along a predetermined direction. When the light propagates to the output end of the plastic composite light guide, it will be uniformly emitted through a specific light-emitting structure or interface.

[0004] However, when using the above-mentioned device, the plastic composite light guide is generally smooth and long. When carrying it, the staff needs to roll up the plastic composite light guide and use a fixing device (such as cable tie) to fix it. If the fixing device is not available, the staff needs to hold the rolled plastic composite light guide by hand. Otherwise, it is easy to become loose and its practicality is poor.

[0005] Therefore, this utility model provides a plastic composite light guide. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a plastic composite light guide to solve the above problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a plastic composite light guide, including a shell, wherein a light-emitting conductor is filled inside the shell, a positioning mechanism is provided on the surface of the shell, and a limiting mechanism is provided at the end of the shell;

[0008] The positioning mechanism includes a positioning ring that surrounds the surface of the outer shell. A positioning band is fixedly connected to one side of the positioning ring. A first Velcro fastener is fixedly connected to one inner end of the positioning band. A second Velcro fastener is fixedly connected to one outer wall of the positioning ring. The first Velcro fastener and the second Velcro fastener are bonded together.

[0009] Preferably, the outer wall of the housing is provided with a connecting groove, and a connecting block is slidably connected to the inner wall of the connecting groove. The connecting block is fixed to the inner wall of the positioning ring. The connecting block can slide in the inner wall of the connecting groove, which makes it easier for the operator to adjust the position of the positioning ring, so as to better fix the housing. Moreover, the setting of the connecting groove can reduce the wall thickness of the housing and increase the light transmittance of the light-emitting conductor.

[0010] Preferably, the connecting block has a T-shaped structure, and the inner wall of the connecting groove has a T-shaped cross-section. The T-shaped design allows the inner wall of the connecting groove and the connecting block to form a limit, making the sliding between them more linear, preventing separation, and preventing the loss of the positioning ring, thus ensuring the fixing operation of the outer shell.

[0011] Preferably, the top of the positioning strip is provided with a light-leaking opening. The light-leaking opening can reduce the coverage area of ​​the positioning strip and increase the light transmittance of the light-emitting conductor, thereby increasing the light radiation area.

[0012] Preferably, the limiting mechanism includes a limiting ring located at the end of the outer shell. A limiting groove is formed on the side of the limiting ring near the outer shell. The light-emitting conductor is in contact with the inner wall of the limiting groove. The limiting ring is fixed to the end of the outer shell. The limiting ring can limit the light-emitting conductor and prevent the light-emitting conductor from sliding out through the inner wall of the outer shell.

[0013] Preferably, the side of the limiting ring away from the outer shell has an arc-shaped structure, and the center of the arc surface of the limiting ring faces the outer shell. The arc-shaped structure design facilitates pressing the light-emitting conductor into the outer shell and facilitates its installation.

[0014] Preferably, the limiting ring has a cavity inside, and the limiting ring has a double-layer structure. The cavity can increase the deformation capability of the limiting ring and further facilitate the installation of the light-emitting conductor. Beneficial effects

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] (1) The plastic composite light guide can fix the outer shell by pulling the positioning strip and making the first hook and loop fastener stick together with the second hook and loop fastener. When the product is used, the positioning strip can be pulled in the opposite direction and the first hook and loop fastener can be separated from the second hook and loop fastener. At this time, the composite light guide can be used. Therefore, it can achieve the effect of making it easy for staff to pick up and carry.

[0017] (2) The plastic composite light guide, through the contact between the light-emitting conductor and the outer wall of the limiting ring, can be pressed into the shell along the arc surface of the limiting ring. The deformation of the cavity can provide it with a certain degree of extensibility, which can facilitate the installation and operation of the staff. Attached Figure Description

[0026] As a further improvement of this utility model, a connecting groove 7 is provided on the outer wall of the outer shell 1, and a connecting block 8 is slidably connected to the inner wall of the connecting groove 7. The connecting block 8 is fixed to the inner wall of the positioning ring 3. The connecting block 8 can slide in the inner wall of the connecting groove 7, which makes it convenient for the staff to adjust the position of the positioning ring 3, so as to better fix the outer shell 1. Moreover, the setting of the connecting groove 7 can reduce the wall thickness of the outer shell 1 and increase the light transmittance of the light-emitting conductor 2.

[0027] As a further improvement of this utility model, the connecting block 8 has a T-shaped structure, and the inner wall cross-section of the connecting groove 7 has a T-shaped structure. The T-shaped structure enables the inner wall of the connecting groove 7 and the connecting block 8 to form a limit, which makes the sliding between the two more linear, avoids separation between the two, and avoids loss of the positioning ring 3, so as to determine the fixing operation of the outer shell 1.

[0028] As a further improvement of this utility model, a light-leaking hole 12 is provided at the top of the positioning band 4. The light-leaking hole 12 can reduce the coverage area of ​​the positioning band 4 and increase the light transmittance of the light-emitting conductor 2, thereby increasing the light radiation area.

[0029] As a further improvement of this utility model, the limiting mechanism includes a limiting ring 9 located at the end of the outer shell 1. A limiting groove 10 is formed on the side of the limiting ring 9 near the outer shell 1. The light-emitting conductor 2 is in contact with the inner wall of the limiting groove 10. The limiting ring 9 is fixed to the end of the outer shell 1. The limiting ring 9 can limit the light-emitting conductor 2 and prevent the light-emitting conductor 2 from sliding out through the inner wall of the outer shell 1.

[0030] As a further improvement of this utility model, the side of the limiting ring 9 away from the outer shell 1 is in the shape of an arc, and the center of the arc surface of the limiting ring 9 faces the outer shell 1. The arc shape facilitates the pressing of the light-emitting conductor 2 into the outer shell 1, which facilitates its installation.

[0031] As a further improvement of this utility model, a cavity 11 is provided inside the limiting ring 9. The limiting ring 9 has a double-layer structure.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] The working principle of this utility model is as follows: When in use, the outer shell 1 is wound up. After the outer shell 1 is wound into a ring, the positioning band 4 is pulled to make the first hook and loop fastener 5 and the second hook and loop fastener 6 stick together. At this time, the outer shell 1 can be fixed, and the connecting block 8 can slide in the inner wall of the connecting groove 7. The position of the positioning ring 3 can be adjusted, which facilitates the operation of the staff. When using the product, the positioning band 4 can be pulled in the opposite direction to separate the first hook and loop fastener 5 and the second hook and loop fastener 6. At this time, the composite light guide can be used. Therefore, it can achieve the effect of easy handling and carrying by the staff.

[0034] When installing the light-emitting conductor 2 in the composite light guide body, the light-emitting conductor 2 can contact the outer wall of the limiting ring 9 and be pressed into the outer shell 1 along the arc surface of the limiting ring 9. The deformation of the cavity 11 can provide it with a certain degree of extensibility, which can facilitate the installation operation of the staff.
