Description

Technical Field

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

[0002] With the increasing popularity of outdoor leisure activities, parasols, as a common tool that combines sunshade and decoration, are facing growing demands for personalization and functionality. Installing light guide strips on the ribs of parasols can create a nighttime atmosphere, provide localized lighting, or serve as signage, showing broad application prospects.

[0003] In existing technologies, light guide strips are generally installed using an adhesive backing method. This involves applying a strong adhesive (such as 3M adhesive or silicone rubber adhesive) to the back of the light guide strip and directly bonding it to the surface of the umbrella ribs. Installation is completed after the adhesive has cured. This allows for quick installation of the light guide strip onto the umbrella ribs, improving installation efficiency.

[0004] Light guide strips installed on sun umbrellas are usually used outdoors. Long-term exposure to the sun can cause the light guide strips to yellow and become brittle (ultraviolet radiation and high temperature environments can cause photo-oxidative degradation of the polymer material of the light guide strip), which will damage the uniformity of light guidance and affect the lighting effect. Therefore, the light guide strips need to be replaced after a period of use to prevent them from failing to provide lighting when in use.

[0005] However, the adhesive on the backing will weaken after being exposed to the sun, making it easy to fall off and potentially hit users, creating a safety hazard. Furthermore, whether it falls off naturally or is removed manually, the adhesive residue is difficult to completely remove. The adhesive residue on the umbrella ribs will cause the adhesion to decrease again during reinstallation, and the cleaning process may damage the umbrella ribs, affecting the product's lifespan. Utility Model Content

[0006] In view of this, the present invention provides a portable light guide strip, which can use a fixing mechanism of fixing frame and mounting block to replace traditional adhesive backing, solve the problems of decreased adhesion due to outdoor sun exposure, light guide strip falling off and adhesive residue. The bolt connection facilitates quick disassembly and replacement of the light guide strip, eliminates the risk of adhesive residue damaging the umbrella frame, improves maintenance efficiency and extends the service life of the umbrella frame.

[0007] To solve the above-mentioned technical problems, this utility model provides a portable light guide strip, including an umbrella rib body, on which a light guide strip body is installed. At least one set of fixing mechanisms is provided on the umbrella rib body and on the outer side wall of the light guide strip body. The fixing mechanisms are used to limit the light guide strip body and prevent it from falling off after being installed on the umbrella rib body.

[0008] Furthermore, the fixing mechanism is configured in two sets, which are symmetrically arranged on the outer side walls at both ends of the light guide strip body to secure the light guide strip body to the umbrella rib body.

[0009] The fixing mechanism includes a fixing frame, which is set on a vertical surface on one side of the umbrella rib body. A mounting block is fixedly connected to the side of the fixing frame away from the light guide strip body. The mounting block is detachably connected to the umbrella rib body by bolts. The fixing frame and the mounting block cooperate to form a limiting space for the light guide strip body, preventing the light guide strip body from falling along the vertical or horizontal direction of the umbrella rib body.

[0010] The mounting block has a mounting hole at the top, and a mounting post is fixedly connected to the inner wall of the mounting hole. A threaded hole is provided at the center of the upper part of the mounting post, which is used to connect the mounting block and the fixing frame to the umbrella rib body with bolts.

[0011] The cross-section of the mounting block is set as a trapezoidal structure, with the inclined end of the trapezoidal structure facing away from the light guide strip body, so that the fixing frame and the umbrella rib body form a limiting angle that matches the outer wall of the light guide strip body, thereby enhancing the snap-fit ​​stability.

[0012] Furthermore, a limiting post is fixedly connected to the outer wall of the mounting column and the lower part of the inner wall of the mounting block. At least one limiting plate is fixedly connected to the outer wall of the limiting post and to the side facing the fixing frame. Two limiting plates can be set to abut and limit one end of the light guide strip body, thereby improving the stability of the light guide strip body after installation.

[0013] A sealing strip is provided at the connection between the fixing frame and the umbrella rib body, and a sealing strip is also provided at the connection between the mounting block and the umbrella rib body. The sealing strip is used to fill the connection gap between the fixing mechanism and the umbrella rib body to form a waterproof sealing structure to prevent rainwater from entering.

[0014] At least two sets of positioning components are provided on the vertical surfaces of both sides of the fixed frame for secondary positioning of the light guide strip body. The positioning components include connecting blocks that are bolted to the vertical surfaces of the fixed frame. A double torsion spring is provided horizontally through the connecting block (i.e., a circular through hole is opened horizontally through the connecting block, and the double torsion spring is installed in the circular through hole). A limiting groove adapted to the connecting center of the double torsion spring is opened on the connecting block, and the connecting center of the double torsion spring is set through the limiting groove.

[0015] Connecting posts are rotatably connected to both vertical surfaces of the connecting block. One end of the connecting post is fixedly connected to the corresponding force arm of the double torsion spring. A clamping plate is fixedly connected to the end of the connecting post away from the connecting block. The clamping plate is designed with an L-shaped structure to hook the side of the umbrella rib body away from the light guide strip body, forming a secondary limit on the light guide strip body. The clamping plate is kept in a clamped state with the side of the umbrella rib body by the elastic restoring force of the double torsion spring.

[0016] A reinforcing plate is fixedly connected between the two clamping plates to enable them to move synchronously.

[0017] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0018] 1. Detachable fixing, solving the defects of adhesive backing: The fixing mechanism (fixing frame and mounting block) replaces the traditional adhesive backing, avoiding the problems of decreased adhesion, light guide strip falling off and adhesive residue caused by outdoor sun exposure. The bolt connection method facilitates the quick disassembly and replacement of the light guide strip body, which not only eliminates the risk of adhesive residue damaging the umbrella frame, but also improves product maintenance efficiency and extends the service life of the umbrella frame.

[0019] 2. Dual limiting structure enhances installation stability: Two sets of symmetrically arranged fixing mechanisms respectively clamp and limit the two ends of the light guide strip body. Together with the limiting angle formed by the trapezoidal mounting block and the limiting plate on the limiting post, the light guide strip is prevented from moving in three directions: vertical, horizontal and lateral, which significantly enhances the clamping stability. The double torsion spring clamping plate in the positioning component maintains the clamping state on the side of the umbrella rib through elastic restoring force, forming a secondary limiting. Even with long-term use, it can ensure the stability of the light guide strip body and avoid the risk of falling off due to vibration or external force.

[0020] 3. Convenient installation and enhanced functionality: The inclined surface of the trapezoidal mounting block serves both guiding and limiting functions, allowing for quick alignment and embedding during installation, reducing the probability of misalignment and improving installation efficiency; the inclined inner wall exerts lateral pressure on the light guide strip, further enhancing the fixing effect; the L-shaped structure and reinforcing plate design of the clamping plate achieve synchronous opening and closing and uniform force distribution, preventing deformation or displacement caused by uneven force distribution, while also enhancing the bending resistance of the clamping structure and extending its service life.

[0021] 4. Waterproof and sealed design, suitable for outdoor environment: Sealing strips are set at the connection between the fixed frame, the mounting block and the umbrella rib body to effectively fill the connection gap and form a waterproof and sealed structure. This prevents rainwater from entering the fixed mechanism and avoids component corrosion or short circuit of the light guide strip caused by rainwater erosion, thus improving the applicability and reliability of the product in complex outdoor environments.

[0022] 5. Flexible adaptive clamping and reduced maintenance costs: The elastic deformation characteristics of the double torsion springs allow the clamping plate to automatically adjust the clamping force within a certain range, eliminating the need for frequent manual calibration. While adapting to different specifications of umbrella ribs, it ensures stable clamping force during long-term use, reducing maintenance frequency and operational difficulty. It is especially suitable for outdoor sun umbrellas and other scenarios that require long-term use. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0035] A type of casual light guide strip, such as Figure 1 As shown: It includes an umbrella rib body 101, on which a light guide strip body 102 is mounted. At least one set of fixing mechanisms is provided on the umbrella rib body 101 and on the outer wall of the light guide strip body 102. The fixing mechanisms are used to limit the light guide strip body 102 and prevent it from falling off after being mounted on the umbrella rib body 101 (when set as a set, it is suitable for shorter light guide strip bodies 102).

[0036] Furthermore, in this embodiment, the fixing mechanism is configured as two sets, which are symmetrically arranged on the outer side walls of both ends of the light guide strip body 102 to snap the light guide strip body 102 onto the umbrella rib body 101, so that both ends of the light guide strip body 102 can be limited and fixed, thereby improving the support effect of the light guide strip body 102 and making the force on both ends of the light guide strip body 102 uniform, avoiding the occurrence of uneven force due to single-point fixing.

[0037] like Figure 1 , 2 As shown in Figure 3, the fixing mechanism includes a fixing frame 201, which is set on a vertical surface on one side of the umbrella rib body 101. An mounting block 202 is fixedly connected to the side of the fixing frame 201 away from the light guide strip body 102. The lower parts of both the fixing frame 201 and the mounting block 202 are hollow structures, and the width and height of the hollow structures are adapted to the width and height of the light guide strip body 102, which can improve the limiting effect on the light guide strip body 102. The mounting block 202 is detachably connected to the umbrella rib body 101 by bolts. The fixing frame 201 and the mounting block 202 cooperate to form a limiting space for the light guide strip body 102, preventing the light guide strip body 102 from falling or detaching along the vertical or horizontal direction of the umbrella rib body 101.

[0038] The upper part of the fixed frame 201 is provided with a raised structure to prevent slippage during installation, improve the stability of the user during installation, and prevent the fixed frame 201 and its components from falling off due to slippage.

[0039] The mounting block 202 has a mounting hole on its upper part, and a mounting post 301 is fixedly connected to the inner wall of the mounting hole. A threaded hole is opened at the upper axis of the mounting post 301, which is used to connect the mounting block 202 and the fixing block to the umbrella rib body 101 with bolts. The bolts can be screwed into the threaded hole on the umbrella rib body 101 to fix the fixing frame 201 and the mounting block 202. This replaces the adhesive backing to install the light guide strip body 102, and facilitates quick disassembly and replacement of the light guide strip body 102.

[0040] like Figure 3 As shown: A limiting post 302 is fixedly connected to the outer wall of the mounting post 301 and the lower part of the inner wall of the mounting block 202. At least one limiting plate 303 is fixedly connected to the outer wall of the limiting post 302 facing the fixing frame 201. In this embodiment, two limiting plates 303 are set. The limiting plates 303 are used to abut and limit one end of the light guide strip body 102, thereby improving the stability of the light guide strip body 102 after installation.

[0041] The two limiting plates 303 can stably limit the contact of one end of the light guide strip body 102, and can reduce the cost of use while enhancing the limiting effect.

[0042] like Figure 1 , 2 As shown: The cross-section of the mounting block 202 is set as a trapezoidal structure, and the inclined end of the trapezoidal structure is set towards the side away from the light guide strip body 102, so that the fixing frame 201 and the umbrella rib body 101 form a limiting angle that matches the outer wall of the light guide strip body 102, thereby enhancing the snap-fit ​​stability.

[0043] The inclined inner wall of the trapezoidal structure exerts a lateral squeezing and limiting effect on one end of the light guide strip body 102, which can effectively prevent the light guide strip body 102 from moving in the vertical or horizontal direction and avoid falling. In addition, the inclined surface of the trapezoidal structure can be used as a guide surface during installation, making it easy to quickly align the light guide strip body 102 and embed it into the limiting space between the fixing frame 201 and the umbrella rib body 101. The guiding effect of the inclined surface can reduce the probability of misalignment during installation, improve the installation speed, and avoid the problem of unstable fixation caused by installation deviation.

[0044] A sealing strip is provided at the connection between the fixing frame 201 and the umbrella rib body 101, and a sealing strip is also provided at the connection between the mounting block 202 and the umbrella rib body 101. The sealing strip is used to fill the connection gap between the fixing mechanism and the umbrella rib body 101 to form a waterproof sealing structure to prevent rainwater from entering.

[0045] like Figure 3 , 4 As shown in Figure 5: At least two sets of positioning components are provided on the vertical surfaces of both sides of the fixing frame 201 to perform secondary positioning of the light guide strip body 102, further improving the positioning effect of the fixing frame 201 on the light guide strip body 102, preventing the fixing frame 201 from tilting towards the end of the light guide strip body 102 after a certain period of use, and preventing the clamping effect of the fixing frame 201 from failing. The positioning components include connecting blocks 401 that are bolted to the vertical surface of the fixing frame 201, which facilitates quick disassembly, assembly, and position replacement of the connecting blocks 401.

[0046] A double torsion spring 601 is transversely inserted through the connecting block 401 (i.e., a circular through hole is opened in the connecting block 401, and the double torsion spring 601 is installed in the circular through hole). A limiting groove 602 adapted to the connecting hub 603 of the double torsion spring 601 is opened on the connecting block 401. The connecting hub 603 of the double torsion spring 601 is set through the limiting groove 602, so that the groove wall of the limiting groove 602 will form a circumferential constraint on the connecting hub 603, preventing the double torsion spring 601 from axially shifting or rotating when subjected to force.

[0047] Therefore, when the two force arms of the double torsion spring 601 undergo elastic deformation, they can maintain a symmetrical torque output direction, thus avoiding clamping failure due to the displacement of the torsion spring position.

[0048] like Figure 4 ,5 As shown: Connecting posts 402 are rotatably connected to both vertical surfaces of the connecting block 401. One end of the connecting post 402 is fixedly connected to the corresponding force arm of the double torsion spring 601. A clamping plate 403 is fixedly connected to the end of the connecting post 402 away from the connecting block 401. After the force arm of the double torsion spring 601 is fixedly connected to the connecting post 402, the torque of the double torsion spring 601 can be directly converted into the clamping force of the clamping plate 403, so that the clamping plate 403 always keeps in close contact with the side of the umbrella rib body 101 away from the light guide strip body 102.

[0049] The double torsion spring 601, in conjunction with the clamping plate 403, ensures that the elastic restoring force of the double torsion spring 601 keeps the clamping plates 403 on both sides of the umbrella rib body 101 in a clamping state. Even if the light guide strip body 102 is displaced due to vibration or external force, the elastic force of the double torsion spring 601 can ensure that the light guide strip body 102 is stably supported for a long time. Furthermore, the elastic deformation of the double torsion spring 601 allows the clamping plate 403 to automatically adjust the clamping force within a certain range without additional adjustment, thus improving the compatibility of assembly and the adaptability of usage scenarios.

[0050] like Figure 2 , 3 As shown in Figure 4, the clamping plate 403 is configured as an L-shaped structure to hook the vertical surface of the umbrella rib body 101 away from the light guide strip body 102, forming a secondary limit on the light guide strip body 102. The clamping plate 403 is kept in a clamped state with the side of the umbrella rib body 101 by the elastic restoring force of the double torsion spring 601.

[0051] The vertical edge of the L-shaped clamping plate 403 can hook onto the side of the umbrella rib body 101 away from the light guide strip body 102, while the horizontal edge forms an upper and lower limit with the fixing frame 201. In conjunction with the first limit of the fixing mechanism, it prevents the light guide strip body 102 from falling off in the vertical or horizontal direction along the umbrella rib body 101.

[0052] (It can also be used without the double torsion spring 601, but the connecting block 401 needs to be installed last and the position of the L-shaped clamping plate 403 needs to be adjusted so that the horizontal plane of the clamping plate 403 is stuck on the side of the umbrella rib body 101 away from the light guide strip body 102.)

[0053] like Figure 4 As shown: A reinforcing plate 501 is fixedly connected between the two clamping plates 403 to enable the two clamping plates 403 to move synchronously. The reinforcing plate 501 rigidly connects the two clamping plates 403 so that when the double torsion spring 601 drives the connecting columns 402 on both sides to rotate (that is, when the clamping plates 403 are pulled apart during disassembly, the elastic force of the double torsion spring 601 will cause the clamping plates 403 to return to their original clamping state), the clamping plates 403 can open and close synchronously, avoiding the situation where one side is clamped and the other side is loose, ensuring that the end of the light guide strip body 102 is subjected to uniform force, and preventing deformation or damage caused by uneven force.

[0054] The reinforcing plate 501 can enhance the bending resistance of the clamping plate 403, prevent the clamping plate 403 from deforming, avoid the weakening of clamping force due to structural loosening after long-term use, and extend the service life.

[0055] When in use, a sealing strip is placed on the mating surface of the fixing frame 201, the mounting block 202 and the umbrella rib body 101. The fixing frame 201 is placed at the marked position on the umbrella rib body 101. The mounting block 202 is fixed to the umbrella rib body 101 with bolts. The bolts pass through the mounting holes on the mounting block 202 and are screwed into the pre-drilled threaded holes on the umbrella rib body 101 (the internal thread of the mounting post 301 is aligned with the threaded hole of the umbrella rib body 101). After installing one set of fixing mechanisms, one end of the light guide strip body 102 is inserted into it, and then the other set of fixing mechanisms is installed on the other end of the light guide strip body 102.

[0056] The connecting block 401 is fixed to the vertical surfaces on both sides of the fixed frame 201 with bolts. The clamping plate 403 is moved outward, and the double torsion spring 601 is compressed to open the clamping plate 403. The vertical clamping plate 403 hooks onto the side of the umbrella rib body 101 away from the light guide strip body 102. After it is released, the elastic restoring force of the double torsion spring 601 causes the clamping plate 403 to clamp the side of the umbrella rib, forming a secondary limit on the light guide strip body 102.

[0057] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0058] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
