Description

Technical Field

[0001] This utility model relates to the field of LED lamp holder technology, specifically to a positioning mold frame for LED lamp holders. Background Technology

[0002] A light-emitting diode, or LED for short, is a semiconductor component. Initially used primarily as an indicator light and display LED board, it has also been used for lighting with the advent of white LEDs. LED lamp holders are categorized by mounting method (such as bayonet and screw-in) and by material (such as bakelite, plastic, metal, and ceramic). As a key component connecting the light source and the circuitry, the positioning accuracy of the LED lamp holder directly affects the assembly efficiency and reliability of LED lamps. Currently, in the production process of LED lamp holders, positioning molds are mainly used in injection molding, stamping, or automated assembly stages.

[0003] In the existing technology, positioning molds are mostly designed for a single model. When processing LED lamp holders of different specifications, a matching positioning mold is required, which makes it difficult for the positioning mold to be compatible with LED lamp holders of different sizes, thus increasing production costs.

[0004] This utility model proposes a positioning mold for LED lamp holders to solve the problem that positioning molds are mostly designed for a single model, making it difficult for them to be compatible with LED lamp holders of different sizes. Utility Model Content

[0005] In order to overcome the problem that the positioning mold frame in the above-mentioned background technology is mostly designed with a single model, making it difficult for the positioning mold frame to be compatible with LED lamp holders of different sizes.

[0006] Based on the above technical concept, the technical solution adopted by this utility model is as follows:

[0007] A positioning mold frame for LED lamp holders includes a positioning base. An adjustment structure is provided inside the positioning base. A rotating rod is connected to the right end of the adjustment structure. A turntable is fixedly installed on the side of the rotating rod away from the adjustment structure. First positioning plates are installed at both ends of the top of the adjustment structure. Both sets of first positioning plates are located on the top of the positioning base. A reinforcing structure is also provided on the top of the positioning base. A connecting structure is provided at the four corners of the bottom of the positioning base. A fixing structure is provided between the turntable and the positioning base.

[0008] The adjustment structure is used to adjust the position of the two sets of first positioning plates.

[0009] Further defining the above technical solution, the adjusting structure includes a bidirectional threaded column, which is rotatably connected to the lower end of the inner cavity of the positioning seat. Both ends of the top of the bidirectional threaded column are meshed with gears. The ends of the two sets of gears opposite to the bidirectional threaded column are meshed with toothed plates. The tops of the two sets of toothed plates are fixedly connected with connecting blocks. The tops of the two sets of connecting blocks are respectively fixedly connected to the bottoms of the two sets of first positioning plates.

[0010] Further defining the above technical solution, the adjustment structure also includes guide rods, which are fixedly connected to the side of the two sets of toothed plates away from the center of the positioning seat. The ends of the two sets of guide rods away from the toothed plates extend out of the positioning seat, and the positioning seat is provided with guide holes for sliding cooperation with the guide rods.

[0011] To further define the above technical solution, reserved slots are provided at both ends of the top of the positioning seat for mating with the connecting block.

[0012] Further defining the above technical solution, the reinforced structure includes two sets of upright plates, which are respectively fixedly installed at the front and rear ends of the top of the positioning seat. Each set of upright plates is screwed with a screw rod in the middle. A rotating wheel is fixedly installed on the side of the two sets of screw rods that are opposite to each other. A second positioning plate is rotatably connected to the side of the two sets of screw rods that are close to each other. Limiting rods are slidably connected between the two sets of second positioning plates and the upright plates.

[0013] To further define the above technical solution, rubber pads are fixedly connected to the side of each of the two sets of first positioning plates and the two sets of second positioning plates near the center of the positioning seat.

[0014] Further defining the above technical solution, the connection structure includes four sets of L-shaped connecting plates, which are fixedly installed at the four corners of the bottom of the positioning seat, and each of the four sets of L-shaped connecting plates has a connection hole inside.

[0015] Further defining the above technical solution, the fixed structure includes four sets of fixed rods, all fixedly connected to the side of the positioning seat near the turntable. Each of the four sets of fixed rods is fixedly connected to a stop block on the side away from the positioning seat. A movable plate is slidably sleeved on the outer side of the four sets of fixed rods. A spring is fixedly connected between the movable plate and the positioning seat. A locking rod is fixedly connected to the end of the movable plate away from the spring. Multiple locking holes are opened on the side of the turntable near the positioning seat for engaging with the locking rod. The multiple locking holes are arranged at equal intervals about the center of the turntable.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model, through the coordinated arrangement of the adjustment structure, rotating rod, turntable and first positioning plate, facilitates the adjustment of the distance between the two sets of first positioning plates according to the specifications of the LED lamp holder, making it convenient to clamp the left and right ends of the LED lamp holder. Through the joint cooperation of the two sets of reinforcing structures, it is convenient to clamp the front and rear ends of the LED lamp holder, thus improving the versatility of the device.

[0018] This utility model, through the design of the connection structure, uses bolts inserted inside the connection holes to fix the L-shaped connection plate, thereby facilitating the overall fixing of the positioning mold frame in a suitable position and improving the stability of the device during use.

[0019] This invention utilizes a fixed structure so that when the turntable needs to be rotated, the locking rod separates from the locking hole, at which point the spring is compressed. When the turntable is not needed to be rotated, the spring force pushes the locking rod into the corresponding locking hole, thereby fixing and locking the turntable in place and preventing rotation due to external forces.

[0025] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0026] Example 1: This example provides a positioning mold for LED lamp holders, such as... Figure 1As shown, this invention can solve the problem that positioning mold frames are mostly designed for a single model, making it difficult for them to be compatible with LED lamp holders of different sizes. It includes a positioning base 1, an adjustment structure 2 inside the positioning base 1, a rotating rod 3 connected to the right end of the adjustment structure 2, a turntable 4 fixedly installed on the side of the rotating rod 3 away from the adjustment structure 2, first positioning plates 5 installed at both ends of the top of the adjustment structure 2, both sets of first positioning plates 5 are located on the top of the positioning base 1, a reinforcing structure 6 is also provided on the top of the positioning base 1, a connecting structure 7 is provided at the four corners of the bottom of the positioning base 1, and a fixing structure 8 is provided between the turntable 4 and the positioning base 1.

[0027] The adjustment structure 2 is used to adjust the position of the two sets of first positioning plates 5.

[0028] Combination Figure 1 In an embodiment of this utility model, the adjusting structure 2 includes a bidirectional threaded column 21, which is rotatably connected to the lower end of the inner cavity of the positioning seat 1. Both ends of the top of the bidirectional threaded column 21 are meshed with gears 22. The ends of the two sets of gears 22 that are away from the bidirectional threaded column 21 are meshed with toothed plates 23. The tops of the two sets of toothed plates 23 are fixedly connected with connecting blocks 26. The tops of the two sets of connecting blocks 26 are respectively fixedly connected to the bottoms of the two sets of first positioning plates 5.

[0029] Combination Figure 1 In an embodiment of this utility model, the adjusting structure 2 further includes guide rods 24, which are fixedly connected to the side of the two sets of toothed plates 23 away from the center of the positioning seat 1. The ends of the two sets of guide rods 24 away from the toothed plates 23 extend out of the positioning seat 1. The positioning seat 1 is provided with guide holes 25 for sliding cooperation with the guide rods 24.

[0030] Combination Figure 1 and Figure 2 In this embodiment of the utility model, both ends of the top of the positioning seat 1 are provided with reserved grooves 11 for cooperating with the connecting block 26.

[0031] The LED lamp holder is placed on top of the positioning seat 1. According to the specifications of the LED lamp holder, the distance between the two sets of first positioning plates 5 is adjusted. During adjustment, the operator rotates the turntable 4. The turntable 4 drives the bidirectional threaded column 21 to rotate through the rotating rod 3. The bidirectional threaded column 21 meshes with the teeth on the surfaces of the two sets of gears 22 through the opposing threads on its surface, driving the two sets of gears 22 to rotate in different directions. The teeth on the surfaces of the two sets of gears 22 mesh with the teeth on the surfaces of the gear plates 23, driving the two sets of gear plates 23 to move and move closer to each other. When the two sets of gear plates 23 move, they drive the two sets of connecting blocks 26 to move and move closer. The two sets of connecting blocks 26 move inside the reserved groove 11 and drive the two sets of first positioning plates 5 to move towards the LED lamp holder until the two sets of first positioning plates 5 are fixedly clamped at the left and right ends of the LED lamp holder. While the two sets of gear plates 23 move, they drive the guide rod 24 to slide inside the guide hole 25, thereby supporting the gear plates 23 and making the gear plates 23 more stable when moving.

[0032] Combination Figure 1 and Figure 2 In an embodiment of this utility model, the reinforcing structure 6 includes two sets of upright plates 61, which are respectively fixedly installed at the front and rear ends of the top of the positioning seat 1. Each set of upright plates 61 is screwed with a screw rod 62 in the middle. Each set of screw rods 62 is fixedly installed with a rotating wheel 63 on the side opposite to each other. Each set of screw rods 62 is rotatably connected with a second positioning plate 64 on the side close to each other. Each set of second positioning plates 64 is slidably connected with a limit rod 65 between it and the upright plate 61.

[0033] The LED lamp holder is initially positioned by two sets of first positioning plates 5. Then, the operator rotates the rotating wheel 63, which drives the screw 62 to rotate. Since the screw 62 is rotatably connected to the second positioning plate 64, and the second positioning plate 64 is slidably connected to the upright plate 61 through the limiting rod 65, the rotation of the screw 62 drives the second positioning plate 64 to move towards the LED lamp holder until the two sets of second positioning plates 64 clamp and fix the front and rear ends of the LED lamp holder, so that the positioning mold can position LED lamp holders of different models.

[0034] Combination Figure 1 and Figure 2 In the embodiments of this utility model, rubber pads are fixedly connected to the side of the two sets of first positioning plates 5 and the two sets of second positioning plates 64 near the center of the positioning seat 1.

[0035] Once the LED lamp holder is fixed, the rubber pads on the inner side of the first positioning plate 5 and the inner side of the second positioning plate 64 directly contact the outer side of the LED lamp holder, thereby increasing the friction between the first positioning plate 5, the second positioning plate 64 and the LED lamp holder. At the same time, it can also protect the outer side of the LED lamp holder and prevent damage to the surface of the LED lamp holder during the clamping process.

[0036] Example 2: Reference Figure 1 and Figure 2 To address the issue of insufficient stability of the positioning mold frame during use, the connecting structure 7 includes four sets of L-shaped connecting plates 71, which are respectively fixedly installed at the four corners of the bottom of the positioning seat 1. Each of the four sets of L-shaped connecting plates 71 has a connecting hole 72 inside.

[0037] After the positioning mold frame has positioned the LED lamp holder, the entire mold frame is moved to the required position, and bolts are inserted into the connecting hole 72 so that the L-shaped connecting plate 71 is fixedly installed in the required position, thereby fixing the entire positioning mold frame and improving the stability of the positioning mold frame during use.

[0038] Example 3: Reference Figure 1 and Figure 3 To address the issue of the turntable 4 easily rotating under external force, a fixed structure 8 is provided, comprising four sets of fixed rods 81, all fixedly connected to the side of the positioning seat 1 near the turntable 4. Each of the four sets of fixed rods 81 is fixedly connected to a stop block 82 on the side away from the positioning seat 1. A movable plate 83 is slidably sleeved on the outer side of the four sets of fixed rods 81. A spring 84 is fixedly connected between the movable plate 83 and the positioning seat 1. A locking rod 85 is fixedly connected to the end of the movable plate 83 away from the spring 84. Multiple locking holes 86 are provided on the side of the turntable 4 near the positioning seat 1 for engaging with the locking rod 85. The multiple locking holes 86 are arranged at equal intervals about the center of the turntable 4.

[0039] When the operator needs to rotate the turntable 4, the moving plate 83 presses against the spring 84. As the moving plate 83 moves, it drives the locking rod 85 to move and separate from the locking hole 86, releasing the locking rod 85 from fixing the turntable 4. At this time, the turntable 4 can be rotated. When the turntable 4 does not need to be rotated, the moving plate 83 is released. Under the elastic force of the spring 84, the moving plate 83 is pushed back to its original position and drives the locking rod 85 to engage in the corresponding locking hole 86, thereby locking the turntable 4 and preventing the turntable 4 from rotating.

[0040] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
