Description

Technical Field

[0001] This utility model relates to the field of light guide plate technology, and in particular to a splicing light guide plate. Background Technology

[0002] A light guide plate is a high-tech product made of optical-grade acrylic or PC sheets. Its design principle is mainly derived from the LCD screen technology of laptops. The light guide plate guides and disperses light by printing light guide points on the bottom surface of the sheet using laser engraving, V-shaped cross grid engraving, or UV screen printing technology.

[0003] By splicing multiple light guide plates, a large area of ​​lighting or display can be easily achieved. For example, Chinese Patent Publication No. "CN215575758U" discloses a spliced ​​light guide plate, relating to the field of light guide plate technology. This addresses the problem that gaps still exist between existing light guide plates when they are spliced ​​together in daily use, affecting the reflectivity of the light guide plate. The light guide plate body has two tenon-and-mortise protruding bases installed at both its upper and lower ends. Two tenon-and-mortise protrusions are also installed at the upper end of each tenon-and-mortise protrusion. Two tenon-and-mortise groove bases are installed on both sides of the light guide plate body. Two tenon-and-mortise groove bases are also installed inside each tenon-and-mortise groove base. Two tenon-and-mortise slide rails are also provided inside each tenon-and-mortise groove base.

[0004] In practice, the light guide plates on both sides are spliced ​​together by mortise and tenon joints and fixed by a magnetic adsorption structure. However, considering that the magnets are prone to damage and weakening of magnetism after long-term use, and because it is inconvenient to replace the magnets, the splicing is unstable and the replacement of the whole unit increases the replacement cost. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of replacing magnets, by proposing a splicing light guide plate.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a splicing light guide plate, including a light guide plate body, the light guide plate body is disposed in a bracket, a connecting structure is provided on the side of the bracket, and the brackets on adjacent sides are spliced ​​and fixed through the connecting structure;

[0008] The connection structure includes a docking part and a mating part. The docking part is detachably connected to a mounting part on its side. The mounting part is equipped with a magnetic element through a stop member. The mating part is equipped with a mating element that attracts the magnetic element on its side.

[0009] Furthermore, the top of one side of the bracket extends downward to form a guide groove, the side of the guide groove connects to the bracket to form the docking part, the mating part is disposed on the other side of the bracket, and the mating part can be slidably connected with the guide groove.

[0010] Furthermore, the bracket is provided with a mounting groove on the opening side of the guide groove, and the side of the mounting groove extends downward to form a snap-fit ​​groove, which communicates with the guide groove;

[0011] The mounting part engages with the mounting groove, and an elastic claw is provided at the bottom of the mounting part. The elastic claw engages with the locking groove through the bottom guide slope, and the elastic claw is flush with the guide groove.

[0012] Furthermore, the side of the mounting part is fixedly connected to the partition through a sliding groove, the magnetic component is disposed in the sliding groove, and a connecting rod is fixedly connected to the back of the magnetic component. The connecting rod is slidably connected to the partition through a compression spring sleeved on the outside.

[0013] Furthermore, limiting grooves are provided on both sides of the free end of the connecting rod, and the top of the mounting part is slidably connected to the stop member through the through groove. The stop member is inserted into the limiting groove through the clearance groove at the bottom.

[0014] Furthermore, the stop member is height-matched with the mounting part, and it is also provided with an anti-slip groove on its top side. The side of the through groove is provided with an inclined surface, which is correspondingly provided with the anti-slip groove.

[0015] The present invention proposes a splicing light guide plate, which has the following advantages: the present invention enables the adjacent brackets to be spliced ​​by setting the docking part and the mating part, and after splicing, the adjacent brackets can be fixed by the attraction between the magnetic parts and the mating parts to prevent free movement between them. When the magnetic parts are damaged or need to be replaced after long-term use, the mounting part and the magnetic parts can be disassembled as a whole by unlocking the elastic claw. Then, the magnetic parts can be disassembled by pulling out the stop and using the spring push, which is convenient for replacement and extends the service life of the bracket. The structure is simple and practical. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-5 A splicing light guide plate includes a light guide plate body, which is disposed in a bracket 1. A connecting structure 2 is provided on the side of the bracket 1, and the brackets 1 on adjacent sides are spliced ​​and fixed through the connecting structure 2.

[0024] The connection structure 2 includes a docking part 21 and a mating part 22. The side of the docking part 21 is detachably connected to an installation part 23. The installation part 23 is provided with a magnetic element 4 through a stop 3. The side of the mating part 22 is provided with a mating element 5 that attracts the magnetic element 4.

[0025] It should be added that the guide groove 24 is set downward along the top of one side of the bracket 1, but the guide groove 24 does not pass through the bracket 1. A magnetic element 4 is set on the opening side of the guide groove 24. By inserting the brackets 1 on both sides, the magnetic element 4 and the mating part 5 are attracted to each other to prevent the brackets 1 on both sides from sliding freely.

[0026] Among them, the magnetic component 4 is a magnet, the mating component 5 is a sheet material made of iron, and a light strip is also installed inside the bracket 1 to provide a light source for the light guide plate. The light strip is set away from the magnetic component 4.

[0027] Furthermore, in existing technologies, magnetic attraction is often used to connect or fix two objects. The magnetic component 4 and the mating component 5 are attracted to prevent the supports 1 on both sides from moving freely. Therefore, the magnetic component 4 itself needs to have appropriate magnetic strength to prevent the magnetic force from being too weak, which would cause the supports 1 on both sides to move freely. When disassembling a pair of supports 1, the pushing force should be greater than the attraction force of the magnetic component 4.

[0028] Furthermore, the top of one side of the bracket 1 extends downward to form a guide groove 24, and the side of the guide groove 24 connects to the bracket 1 to form the docking part 21. The mating part 22 is disposed on the other side of the bracket 1, and the mating part 22 can be slidably connected with the guide groove 24. Specifically, the side of the guide groove 24 connects to the bracket 1 in a T-shaped structure.

[0029] Furthermore, the bracket 1 is provided with a mounting groove 25 on the opening side of the guide groove 24, and the side of the mounting groove 25 extends downward to form a snap-fit ​​groove 251, which is connected to the guide groove 24.

[0030] The mounting part 23 engages with the mounting groove 25. An elastic claw 26 is provided at the bottom of the mounting part 23. The elastic claw 26 engages with the locking groove 251 through the guide slope at the bottom, and the elastic claw 26 is flush with the guide groove 24.

[0031] It is worth mentioning that the elastic claw 26 is preferably made of materials with deformation capabilities such as rubber and plastic. The bottom of the elastic claw 26 is provided with a guide slope on the side near the guide groove 24. The elastic claw 26 contacts and slides against the locking groove 251 through the guide slope, and reduces the friction force generated when contacting.

[0032] It should be noted that when the snap-fit ​​groove 251 and the elastic claw 26 snap-fit ​​together, there is a certain amount of clearance between them to prevent the elastic claw 26 from sticking to the snap-fit ​​groove 251 and being unable to detach from the snap-fit ​​groove 251 through abutment deformation.

[0033] More specifically, the side of the mounting part 23 is fixedly connected to the partition layer 231 through a sliding groove. The magnetic component 4 is disposed in the sliding groove, and a connecting rod 6 is fixedly connected to the back of the magnetic component 4. The connecting rod 6 is slidably connected to the partition layer 231 through a compression spring 61 sleeved on the outside. Specifically, one side of the sliding groove is connected to the mounting part 23.

[0034] In general, limiting grooves 62 are provided on both sides of the free end of the connecting rod 6, and the top of the mounting part 23 is slidably connected to the stop member 3 through the through groove 232. The stop member 3 is inserted into the limiting groove 62 through the clearance groove at the bottom.

[0035] Finally, the stop member 3 is height-matched with the mounting part 23, and it is also provided with an anti-slip groove on its top side. The side of the through groove 232 is provided with an inclined surface, which is correspondingly provided with the anti-slip groove.

[0036] It should be added that the stop 3 has a U-shaped structure, and when it passes through the mounting part 23 and is inserted into the limiting groove 62, it serves two purposes: first, it stops the mounting part 23, and second, it fixes the connecting rod 6 through the stop, thereby fixing the magnetic part 4.

[0037] The connecting rod 6 and the magnetic component 4 can be detachably fixed by adhesive bonding.

[0038] The inclined surface provides space, allowing the stop 3 to be removed using a fingernail or similar object through the anti-slip groove. The stop 3 and the elastic claw 26 are flush with the mounting part 23 and the guide groove 24, respectively, to prevent protrusion from affecting installation and aesthetics.

[0039] Working method: When it is necessary to splice the brackets 1 on both sides of the adjacent side, the mating part 21 of one bracket 1 is inserted into the mating part 22 of the other bracket 1 by sliding. After insertion, the magnetic part 4 and the mating part 5 are attracted to each other to prevent the brackets 1 on both sides from moving randomly.

[0040] When it is necessary to separate the two brackets 1, simply push one of the brackets 1 in the opposite direction of insertion. When the pushing force is greater than the attraction force of the magnetic component 4, the spliced ​​pair of brackets 1 can be separated.

[0041] Furthermore, by pushing the elastic claw 26 to disengage it from the locking groove 251, the mounting part 23 and the magnetic component 4 can be connected for disassembly. Alternatively, the stop 3 can be pulled out using the anti-slip groove through the clearance space of the inclined surface, such as by using a fingernail. The connecting rod 6 loses its fixation and the magnetic component 4 slides under the action of the compression spring 61, allowing the magnetic component 4 to be removed.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
