[0004] The LED horizontal spiral flexible filament core column fixes the LED flexible filament to the support, and the support and bracket fix the filament to the base. The structure protects the filament with the outer shell. The structure does not describe how the base and the outer shell are installed and fixed together. When the filament needs to be replaced, the outer shell cannot be disassembled efficiently. Utility Model Content

[0005] The purpose of this invention is to provide an LED horizontal spiral flexible filament core column, which solves the problem of convenient disassembly and assembly of the filament core column.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an LED horizontal spiral flexible filament core column, comprising a bulb and a fixing structure. The fixing structure is installed on the outer wall of the bottom of the bulb. The fixing structure includes a fixing band, with an insert block and a sleeve block fixedly connected to both ends of the fixing band, respectively. An insert rod is inserted into the inner wall of one side of the sleeve block, and a clamping block is fixedly connected to the top of the insert rod. A tension spring is fixedly connected to the inner wall of the clamping block and the sleeve block that are close to each other. The tension spring is sleeved on the outside of the insert rod. A connecting rod is rotatably connected to the inner wall of the bottom of the sleeve block, and rotating blocks are fixedly connected to the outer walls of both ends of the connecting rod. The two rotating blocks are respectively located on the outer walls of the sleeve block and the clamping block on both sides. The purpose of this setup is to fix the flexible filament inside the spiral flexible filament tube during the use of the LED horizontal spiral flexible filament core column. Then, the spiral flexible filament core column base is inserted into the top inner wall of the socket, limiting the position of the spiral flexible filament core column through the socket. Next, the lampshade is placed over the connection between the spiral flexible filament core column and the socket, and the groove at the bottom of the lampshade limits its position outside both. The fixing strap is wrapped around the outside of the socket and the lampshade. Then, the clamp is pushed upwards, causing the clamp to move the insert rod upwards within the slot of the sleeve block. The tension spring connecting the two is pulled upwards by the upward force, opening it. After the clamp moves upwards and separates from the sleeve block, the insert block is pulled again to make the protrusion of the sleeve block fit into the slot. Releasing the clamp causes the tension spring to contract downwards, causing the insert rod to return to its original position. The insert rod then moves the clamp back to its original position. At the top of the clamping slot, the protrusion on the clamping block aligns with the slot on the top of the insert block and is fixed in place. Finally, rotate one side of the rotating block so that the connecting rod connected to it drives the other side of the rotating block to rotate. Rotate the two rotating blocks to both sides of the connection between the sleeve block and the clamping block to prevent the sleeve block and the clamping block from shifting up, down, left, or right. Fix the two rotating blocks by locking the middle part of the external connecting rod inside the clamping block. This structure fixes the fixing band around the outside of the connection between the socket and the lampshade, fixing the socket, the spiral flexible filament core, and the lampshade together. When it is necessary to disassemble the spiral flexible filament core, rotate the rotating block to release the fixation of the sleeve block and the clamping block, and pull the clamping block upward to remove the slot from the sleeve block. This structure can quickly release the fixed connection between the socket, the spiral flexible filament core, and the lampshade, making disassembly and assembly convenient.

[0008] Furthermore, slots are provided on the upper and lower outer walls of the insert block, and the insert block is inserted between the sleeve block and the clamping block. The purpose of this arrangement is that, during the use of the LED horizontal spiral flexible filament core, the fixing strap is wrapped around the outside of the socket and the lampshade. After the clamping block moves upward and separates from the sleeve block, the insert block is pulled to make the protrusion of the sleeve block fit into the slot, thus fixing the fixing strap around the outside of the connection between the socket and the lampshade.

[0009] Furthermore, protrusions are provided on the inner walls of the adjacent sides of the sleeve block and the clamping block, and the two protrusions are respectively engaged in the two slots. The purpose of this arrangement is that during the use of the LED horizontal spiral flexible filament core column, pulling the insert block causes the protrusion of the sleeve block to be embedded in the slot, and then releasing it causes the tension spring to retract downward, driving the insert rod to return downward. The insert rod drives the clamping block to return to its original position and clamp the top of the slot. At this time, the protrusion at the clamping block is correspondingly embedded and fixed in the slot at the top of the insert block.

[0010] Furthermore, a locking block is fixedly connected to the bottom outer wall of the sleeve block, and another connecting rod is fixedly connected to the side of the two rotating blocks that are close to each other. The rod of the other connecting rod is locked inside the locking block. The purpose of this arrangement is to prevent the sleeve block and clamp block from shifting up, down, left, or right when rotating the two rotating blocks to the sides of the connection between the sleeve block and the clamp block during the use of the LED horizontal spiral flexible filament column, and to fix the two rotating blocks by locking the middle part of the external connecting rod inside the locking block.

[0011] Furthermore, the bulb includes a socket, a spiral flexible filament core inserted into the inner top wall of the socket, and a lampshade fitted around the outer perimeter of the socket. The purpose of this arrangement is that, during the use of the LED horizontal spiral flexible filament core, the flexible filament is inserted into the spiral flexible filament core tube and fixed therein, then the base of the spiral flexible filament core is inserted into the inner top wall of the socket, limiting the position of the spiral flexible filament core through the socket, and finally the lampshade is fitted over the connection between the spiral flexible filament core and the socket, with the lampshade's bottom groove limiting its position outside both.

[0012] Furthermore, the fixing strap is wrapped around the outer wall of the bottom of the lampshade, and the insert and sleeve blocks fix the two ends of the fixing strap at the connection between the socket and the lampshade. The purpose of this arrangement is that, during the use of this LED horizontal spiral flexible filament core, the fixing strap is wrapped around the outside of the socket and the lampshade, and fixed between the sleeve and clamp blocks by the insert blocks, so that the two ends of the fixing strap are fixedly connected, and the fixing strap is fixedly wrapped around the outer wall of the socket and the lampshade for fixation.

[0013] This utility model has the following beneficial effects:

[0014] (1) This utility model uses a tension spring and a rotating block to pull the insert block so that the protrusion of the sleeve block is embedded in the slot. When you release the spring, it retracts downward and drives the insert rod to return downward and clamp the top of the slot, so that the clamp block and the insert block are fixed in correspondence. Rotate the two rotating blocks to both sides of the connection between the sleeve block and the clamp block to prevent the sleeve block and the clamp block from shifting up, down, left, and right. When replacing the lamp core, rotate the rotating block to release the fixation of the sleeve block and the clamp block, and pull the clamp block upward to remove the slot from the sleeve block.

[0015] (2) This utility model uses a lampshade, a spiral flexible filament core and a socket to fix the flexible filament inside the spiral flexible filament core tube. Then, the base of the spiral flexible filament core is inserted into the top inner wall of the socket, and the socket limits the spiral flexible filament core. Then, the lampshade is put on the connection between the spiral flexible filament core and the socket, and the groove at the bottom of the lampshade limits the lampshade to the outside of the two. This design makes it easy to fix or unfix the three together through the fixing structure, and is convenient for disassembly and assembly.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 As shown, this utility model is an LED horizontal spiral flexible filament core column, including a bulb 1 and a fixing structure 2. The fixing structure 2 is installed on the outer wall of the bottom of the bulb 1. The fixing structure 2 includes a fixing band 201. The two ends of the fixing band 201 are respectively fixedly connected to an insert block 202 and a sleeve block 204. An insert rod 209 is inserted into the inner wall of one side of the sleeve block 204. A clamping block 205 is fixedly connected to the top of the insert rod 209. A tension spring 210 is fixedly connected to the inner wall of the clamping block 205 and the sleeve block 204 on the side that are close to each other. The tension spring 210 is sleeved on the outside of the insert rod 209. A connecting rod 207 is rotatably connected to the inner wall of the bottom of the sleeve block 204. Rotating blocks 206 are fixedly connected to the outer walls of both ends of the connecting rod 207. The two rotating blocks 206 are respectively located on the outer walls of the sleeve block 204 and the clamping block 205. The purpose of this setup is to allow the flexible filament to be inserted into the spiral flexible filament post 102 and fixed during use, and then the base of the spiral flexible filament post 102 is inserted into the top inner wall of the socket 101. The socket 101 then limits the position of the spiral flexible filament post 102. The lampshade 103 is then placed over the connection between the spiral flexible filament post 102 and the socket 101, and the groove at the bottom of the lampshade 103 limits its position outside both. The fixing strap 201 is then placed around the connection. Wrap the clamp 205 around the outside of the socket 101 and the lampshade 103, then push the clamp 205 upward. The clamp 205 drives the insert rod 209 upward within the slot of the sleeve block 204. The tension spring 210 connecting the two is pulled upward by the upward force and opens. After the clamp 205 moves upward and separates from the sleeve block 204, pull the insert 202 to make the protrusion 211 of the sleeve block 204 fit into the slot 203. Then release the clamp 202 to retract the tension spring 210 downward and drive the insert rod 209 to return to its original position. The insert rod 209 drives the clamp 205 to return to its original position and clamp the slot 203. At the top of 03, the protrusion 211 at the clamping block 205 is correspondingly embedded and fixed in the slot 203 at the top of the insert block 202. Finally, rotate one side of the rotating block 206 so that the connecting rod 207 connected to it drives the other side of the rotating block 206 to rotate. Rotate the two rotating blocks 206 to both sides of the connection between the sleeve block 204 and the clamping block 205 to prevent the sleeve block 204 and the clamping block 205 from shifting up, down, left, or right. By locking the middle part of the external connecting rod 207 in the clamping block 208, the two rotating blocks 206 are fixed. This structure will fix the belt 2 01 is fixed around the outside of the connection between the socket 101 and the lampshade 103, fixing the socket 101, the spiral flexible filament core 102 and the lampshade 103 together. When it is necessary to disassemble the spiral flexible filament core 102, rotate the rotating block 206 to release the fixing of the sleeve block 204 and the clamping block 205, and pull the clamping block 205 upward to remove the slot 203 from the sleeve block 204. This structure can quickly release the fixed connection between the socket 101, the spiral flexible filament core 102 and the lampshade 103, making disassembly and assembly convenient.

[0026] The upper and lower outer walls of the insert 202 are provided with slots 203, and the insert 202 is inserted between the sleeve block 204 and the clamping block 205. The purpose of this arrangement is that during the use of the LED horizontal spiral flexible filament core, the fixing strap 201 is wrapped around the outside of the socket 101 and the lampshade 103. After the clamping block 205 moves up and separates from the sleeve block 204, the insert 202 is pulled so that the protrusion 211 of the sleeve block 204 is inserted into the slot 203, and the fixing strap 201 is fixedly wrapped around the outside of the connection between the socket 101 and the lampshade 103.

[0027] On the inner walls of the adjacent sides of the sleeve block 204 and the clamping block 205, there are protrusions 211 respectively, and the two protrusions 211 are respectively engaged in the two slots 203. The purpose of this arrangement is that during the use of the LED horizontal spiral flexible filament core column, when the insert block 202 is pulled, the protrusions 211 of the sleeve block 204 are embedded into the slots 203. When the hand is released, the tension spring 210 retracts downward, causing the insert rod 209 to return downward. The insert rod 209 causes the clamping block 205 to return to its original position and clamp the top of the slot 203. At this time, the protrusions 211 at the clamping block 205 are correspondingly embedded and fixed in the slots 203 at the top of the insert block 202.

[0028] A locking block 208 is fixedly connected to the bottom outer wall of the sleeve block 204. Another connecting rod 207 is fixedly connected to the side of the two rotating blocks 206 that are close to each other, and the rod of the other connecting rod 207 is locked inside the locking block 208. The purpose of this arrangement is to prevent the sleeve block 204 and the clamping block 205 from shifting up, down, left, and right when the two rotating blocks 206 are rotated to the sides of the connection between the sleeve block 204 and the clamping block 205 during the use of the LED horizontal spiral flexible filament column, and to fix the two rotating blocks 206 by locking the middle part of the external connecting rod 207 inside the locking block 208.

[0029] The bulb 1 includes a socket 101, a spiral flexible filament core 102 inserted into the top inner wall of the socket 101, and a lampshade 103 fitted onto the outer walls of the socket 101. The purpose of this arrangement is that, during the use of the LED horizontal spiral flexible filament core, the flexible filament is inserted into the spiral flexible filament core 102 tube and fixed therein. Then, the base of the spiral flexible filament core 102 is inserted into the top inner wall of the socket 101, limiting the position of the spiral flexible filament core 102 through the socket 101. Finally, the lampshade 103 is fitted onto the connection between the spiral flexible filament core 102 and the socket 101, and the groove at the bottom of the lampshade 103 limits its position outside both.

[0030] The fixing strap 201 is wrapped around the outer wall of the bottom of the lampshade 103. The insert block 202 and the sleeve block 204 fix the two ends of the fixing strap 201 to the connection between the socket 101 and the lampshade 103. The purpose of this arrangement is that, during the use of the LED horizontal spiral flexible filament core, the fixing strap 201 is wrapped around the outside of the socket 101 and the lampshade 103, and fixed between the sleeve block 204 and the clamp block 205 by the insert block 202, so that the two ends of the fixing strap 201 are fixedly connected, and the fixing strap 201 is fixedly wrapped around the outer wall of the socket 101 and the lampshade 103 for fixation.

[0031] In use, during the operation of this LED horizontal spiral flexible filament core post, the flexible filament is inserted into the spiral flexible filament core post 102 tube and fixed therein. Then, the base of the spiral flexible filament core post 102 is inserted into the top inner wall of the socket 101, thereby limiting the position of the spiral flexible filament core post 102 through the socket 101. Next, the lampshade 103 is placed over the connection between the spiral flexible filament core post 102 and the socket 101, and the groove at the bottom of the lampshade 103 limits its position outside both. Finally, the fixing strap 201 is wrapped around the socket. Outside of 101 and lampshade 103, the clamping block 205 is then pushed upwards. The clamping block 205 drives the insert rod 209 upwards within the slot of the sleeve block 204. The tension spring 210 connecting the two is pulled upwards by the upward force and opens. After the clamping block 205 moves upwards and separates from the sleeve block 204, the inserting block 202 is pulled to make the protrusion 211 of the sleeve block 204 fit into the slot 203. Then, the spring 210 is released, causing the insert rod 209 to return to its original position. The insert rod 209 drives the clamping block 205 to return to its original position and clamp the slot 203. At the top, the protrusion 211 at the clamping block 205 is aligned with the slot 203 at the top of the insert block 202 and fixed in place. Finally, one side of the rotating block 206 is rotated so that the connecting rod 207 connected to it drives the other side of the rotating block 206 to rotate. The two rotating blocks 206 are rotated to the sides of the connection between the sleeve block 204 and the clamping block 205 to prevent the sleeve block 204 and the clamping block 205 from shifting up, down, left, or right.
