In particular, some LED light strips are used in places high above the ground in daily use, and the staff need to use escalators to climb up for splicing and disassembly. When on the escalator, the staff may need to hold the escalator with one hand, and it will be inconvenient to operate with both hands at this time. For example, in some narrow places, the operating space is small and it is not conducive to operation when putting both hands in, resulting in low work efficiency.

[0005] In view of this, the utility model provides a combined splicing type LED light bar. Utility Model Content

[0006] The purpose of the utility model is to solve the above-mentioned shortcomings and provide a device that can quickly separate two light strips, thereby improving the efficiency when replacing light strips.

[0007] Therefore, the utility model provides a combined spliced ​​LED light strip, which includes a first light strip and a second light strip, wherein the first light strip and the second light strip have opposite sides that are clamped to each other, an end of the first light strip opposite to the second light strip is fixedly connected with a clamping block, an end of the clamping block away from the first light strip is fixedly connected with a clamping plate, a cavity is opened inside the first light strip, and a slide rail is fixedly installed inside the cavity, a push rod is slidably connected to the inner wall of the slide rail, an end of the push rod away from the first light strip is fixedly connected with a first magnetic block, the upper side of the push rod is attached to the lower side of the clamping block, a pressure rod is slidably connected to the inside of the first light strip, the upper end of the pressure rod passes through the upper wall of the first light strip, and the lower end of the pressure rod abuts against the end of the push rod that abuts against the first light strip.

[0008] As a further improvement of the technical solution, a card interface is provided inside the second light strip, and the inner wall of the card interface is rotatably connected to a rotating plate, and the inner side of the rotating plate and the inner wall of the card interface are fixedly connected to a first spring, and the first spring is used for the rotating plate to perform a reset movement, and a sliding groove is provided on the side wall of the rotating plate, and an inclined plate is slidably connected to the inner wall of the sliding groove, and a second magnetic block is fixedly connected to the lower end of the inclined plate, and a notch is provided on the upper side of the second light strip.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In this combined splicing LED light strip, the staff can perform one-handed operation when replacing the last matching combination. By picking up the first light strip and pressing the pressure rod, the pressure rod moves downward, and the vertical force is converted into horizontal force through the inclined surface to push out the first magnetic block.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] LED light strip refers to the assembly of LED on a strip of FPC (flexible circuit board) or PCB hard board. The flexible LED light strip uses FPC as the assembly circuit board and SMD LED for assembly, so that the thickness of the product is only 0.1CM, which does not take up space and is suitable for use in irregular places and places with small spaces. It can also be bent and wound arbitrarily, so it is suitable for any combination of various patterns in advertising decoration. Therefore, Figure 1-Figure 6 As shown, a combined splicing type LED light strip includes a first light strip 1 and a second light strip 12. The first light strip 1 and the second light strip 12 are mutually clamped on opposite sides. The first light strip 1 is fixedly connected with a clamping block 5 at one end opposite to the second light strip 12. The clamping block 5 is used for connecting the first light strip 1 and the second light strip 12. The clamping block 5 is fixedly connected with a clamping plate 51 at one end away from the first light strip 1. The clamping plate 51 is used to strengthen the clamping effect of the clamping block 5. A cavity is opened inside the first light strip 1, and a slide rail 42 is fixedly installed inside the cavity. The slide rail 42 is used to slide and connect the push rod 4 to move the push rod 4. The trajectory is limited to ensure the normal operation of the push rod 4. The inner wall of the slide rail 42 is slidably connected with the push rod 4, and the push rod 4 is used to push the first magnetic block 41 to move. The end of the push rod 4 away from the first light strip 1 is fixedly connected with the first magnetic block 41. The first magnetic block 41 cooperates with the second magnetic block 57 to operate according to the principle that magnets of the same charge repel each other. The upper side of the push rod 4 is attached to the lower side of the clamping block 5. The inside of the first light strip 1 is slidably connected with a pressure rod 3, and the pressure rod 3 is used to press down and push the push rod 4 to move. The upper end of the pressure rod 3 passes through the upper wall of the first light strip 1, and the lower end of the pressure rod 3 abuts against the end of the push rod 4 close to the first light strip 1;

[0030] In order to make the second light strip 12 and the first light strip 1 more stable and firm during the splicing process, a card interface 52 is provided inside the second light strip 12, and the card interface 52 is used for inserting the card block 5. The inner wall of the card interface 52 is rotatably connected with a rotating plate 53, and the rotating plate 53 is used for inserting the card block 5 to drive the inclined plate 55 to move so that the card block 5 can be inserted. The inner side of the rotating plate 53 and the inner wall of the card interface 52 are fixedly connected with a first spring 58. The first spring 58 is used for rotating the rotating plate 53. The reset movement is performed so that the inclined plate 55 is clamped to its clamping plate 51. A slide groove 54 is provided on the side wall of the rotating plate 53. The inner wall of the slide groove 54 is slidably connected with the inclined plate 55. The slide groove 54 enables the inclined plate 55 to move up and down on the side wall of the rotating plate 53, and ensures that the moving trajectory is correct to ensure normal operation. The lower end of the inclined plate 55 is fixedly connected to a second magnetic block 57. A notch 56 is provided on the upper side of the second light strip 12. The notch 56 is used to store the inclined plate 55 when it moves up, so that it can be reset normally.

[0031] Considering that the first light strip 1 and the second light strip 12 can emit light normally after being connected, a plurality of light bulbs 23 are fixedly connected to the outside of the first light strip 1 and the second light strip 12, a circuit plug 2 is fixedly connected to the upper side of the first light strip 1, and a circuit socket 21 is fixedly connected to the upper side of the second light strip 12. The circuit plug 2 and the circuit socket 21 are connected so that the power supply between the first light strip 1 and the second light strip 12 is connected, thereby ensuring the normal operation of the light bulbs 23;

[0032] In order to make the first light strip 1 and the second light strip 12 recyclable and reduce the cost, the lower end of the pressure rod 3 is an inclined surface, and one end of the push rod 4 that fits the inclined surface of the lower end of the pressure rod 3 is an inclined surface, and fits the inclined surface of the lower end of the pressure rod 3. Due to the characteristics of the inclined surface structure, when the push rod 4 moves along the inclined surface of the pressure rod 3, the vertical force is converted into a horizontal force through the inclined surface, which can achieve smooth motion transmission, reduce mechanical shock and vibration, and enable the pressure rod 3 and the push rod 4 to withstand greater force, improve the mechanical stability and durability, and a pressure plate 31 is fixedly connected to one side of the pressure rod 3. The pressure plate 31 and the pressure rod 3 form a solid whole, ensuring a stable connection between them. A second spring 32 is fixedly connected between the lower side of the pressure plate 31 and the bottom wall of the internal cavity of the first light strip 1. When the pressure rod 3 is pressed down by an external force, it compresses the second spring 32, causing the spring to deform. Once the external force disappears, the second spring 32 will quickly return to its original state and generate a strong elastic force. This elastic force will push the pressure plate 31 upward, and then drive the pressure rod 3 to move upward and reset. This process not only ensures that the pressure rod 3 can quickly and accurately return to the original position, but also effectively improves the stability and reliability of the entire structure through the reset mechanism of the spring. The existence of the second spring 32 not only enables the pressure rod 3 to achieve the automatic reset function, but also buffers the impact force when the pressure rod 3 is pressed down to a certain extent, thereby extending the service life of the equipment. In addition, by using the reset mechanism of the second spring 32, the connection between the pressure rod 3 and the pressure plate 31 is made more stable and reliable, while improving the overall performance and service life of the equipment. A limit rod 33 is fixedly connected between the upper wall and the bottom wall of the internal cavity of the first light strip 1. The limit rod 33 passes through the interior of the pressure plate 31 and the second spring 32 from top to bottom. The limit rod 33 is used for the second spring 32 to work normally when compressed, ensuring that the second spring 32 will not deviate. The design of the limit rod 33 is that it passes through the interior of the pressure plate 31 and the second spring 32, providing a stable track for the second spring 32, so that it can move along this track when it is under pressure, thereby avoiding the occurrence of deviation, which not only ensures that the second spring 32 can work normally when compressed, but also greatly improves the stability and durability of the entire mechanical structure.

[0033] In order to ensure that the first light strip 1 and the second light strip 12 can be more stable when separated, the internal size of the slot 56 is adapted to the inclined plate 55, and the slot 56 is vertically located directly above the inclined plate 55, ensuring that the inclined plate 55 can accurately enter the slot 56 when moving upward, thereby ensuring the normal operation. The opposite side of the first magnetic block 41 and the second magnetic block 57 is the end of the magnets that repel each other, so that the thrust generated by the repulsion causes the inclined plate 55 to move upward, thereby achieving the first light strip 1 to quickly detach from the interior of the second light strip 12, thereby improving work efficiency.

[0034] Considering that the current LED light strips require both hands to operate during the splicing and disassembly process, in daily use, the LED light strips may be used in some places high above the ground, and the staff need to use escalators to climb up for splicing and disassembly. When the staff is on the escalator, they may need to hold the escalator with one hand, which will cause inconvenience in operating with both hands. For example, in some narrow places, the operating space is small and not conducive to operation, resulting in low work efficiency. The improvements of this embodiment are:

[0035] After pressing the pressure rod 3, the pressure rod 3 moves downward and pushes the push rod 4 to slide inside the slide rail 42 through the inclined surface, and then the push rod 4 pushes the first magnetic block 41 to move. When the first magnetic block 41 moves below the second magnetic block 57, the repulsive force between the first magnetic block 41 and the second magnetic block 57 causes the second magnetic block 57 to move upward, so that the upward movement of the second magnetic block 57 pushes the inclined plate 55 to move upward, and then the inclined plate 55 moves upward along the slide groove 54 until it moves to the inside of the slot 56. At this time, the clamping plate 51 is separated from the inclined plate 55, and the staff can then pull out the first light strip 1 and the second light strip 12.

[0036] For recycling, the side wall of the pressure rod 3 is fixedly connected with a pressure plate 31, and the lower side of the pressure plate 31 and the bottom wall of the internal cavity of the first light strip 1 are fixedly connected with a second spring 32. The upper wall and the bottom wall of the internal cavity of the first light strip 1 are fixedly connected with a limit rod 33, and the limit rod 33 passes through the inside of the pressure plate 31 and the second spring 32 from top to bottom, so that when the pressure rod 3 is pressed down by an external force, it will compress the second spring 32 and deform the second spring 32. Once the external force disappears, the second spring 32 will quickly return to its original state, and then drive the pressure rod 3 to move up together, ensuring that the pressure rod 3 can quickly and accurately return to the original position, which is convenient for the next work.

[0037] In summary, the working principle of this solution is as follows:

[0038] When the staff assembles the first light strip 1 and the second light strip 12, the staff docks the first light strip 1 with the second light strip 12. When the first light strip 1 is moved, the clamping block 5 will be inserted into the clamping interface 52. At this time, the clamping block 5 pushes the inclined plate 55, and the inclined plate 55 moves under the thrust, driving the rotating plate 53 to rotate, so that the clamping block 5 enters the clamping interface 52. At the same time, the rotating plate 53 squeezes the first spring 58 when rotating. When the clamping plate 51 is separated from the inclined plate 55, the first spring 58 loses the external force and resets, driving the rotating plate 53 to reset, so that the inclined plate 55 clamps the clamping plate 51;

[0039] When the first light strip 1 or the second light strip 12 needs to be replaced, the staff needs to press the pressure rod 3, and the pressure rod 3 moves downward, and the push rod 4 is pushed to slide inside the slide rail 42 through the inclined surface at the lower end of the pressure rod 3, and then the push rod 4 pushes the first magnetic block 41 to move. When the first magnetic block 41 moves below the second magnetic block 57, the repulsive force between the first magnetic block 41 and the second magnetic block 57 causes the second magnetic block 57 to move upward, so that the upward movement of the second magnetic block 57 pushes the inclined plate 55 to move upward, and then the inclined plate 55 moves upward along the slide groove 54 until it moves to the inside of the slot 56. At this time, the clamping plate 51 is separated from the inclined plate 55, and the staff can pull the first light strip 1 out of the second light strip 12.
