Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and in particular to an ultra-long LED printed circuit board. Background Technology

[0002] Circuit boards are used to miniaturize and visualize circuits, playing a crucial role in the mass production of fixed circuits and optimizing the layout of electrical appliances. Circuit boards are also called printed circuit boards (PCBs). Currently, when installing LED PCBs onto mounting housings, the bottom of the LED PCB is typically brought into contact with the bottom of the mounting housing and secured with screws.

[0003] Existing technologies, such as Chinese Patent Publication No. CN216752233U, disclose an ultra-long LED printed circuit board, including a mounting shell and a circuit board body. A fixed plate is provided on the inner wall surface of the mounting shell, and a limiting groove is formed on the surface of the mounting shell. An insertion hole is formed through the limiting groove, and a movable fixed plate is inserted into the insertion hole. Both the movable and fixed plates have fixing holes on their surfaces. In this invention, the use of the fixed and movable fixed plates facilitates the installation of the circuit board body. During installation, the operator places the circuit board body on the fixed plate, aligns the fixing holes, and then moves the movable fixed plate out of the insertion hole onto the circuit board body. Finally, it is secured with fasteners. This method is simple to operate, facilitates the installation of the circuit board body, and ensures that the circuit board body does not contact the bottom of the mounting shell, thus facilitating heat dissipation and improving its service life. However, when installing ultra-long LED printed circuit boards, this utility model requires moving and adjusting the positions of multiple movable fixing plates, making the installation and disassembly process time-consuming and labor-intensive.

[0004] To address the issue of the difficulty in quickly and easily installing and removing ultra-long LED printed circuit boards, existing equipment typically involves contacting the bottom of the LED circuit board with the bottom of the mounting housing and securing it with screws. This process is time-consuming and labor-intensive, hinders heat dissipation, and can negatively impact the lifespan of the circuit board. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing ultra-long LED printed circuit boards are not convenient for quick and easy installation and disassembly, and to propose an ultra-long LED printed circuit board.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an ultra-long LED printed circuit board, comprising a mounting frame, a circuit board body, and a loading and unloading device. The circuit board body is disposed inside the mounting frame, and the loading and unloading device is disposed on the surface of the mounting frame. The loading and unloading device includes a fixing component, an adjusting component, and an auxiliary component. The fixing component includes a screw, which is rotatably connected to the inner wall of the mounting frame. The surface of the screw is threadedly connected to the fixing frame. A limit rod is fixedly connected to the surface of the mounting frame, and the fixing frame is slidably connected to the surface of the limit rod. A ventilation groove is formed on the surface of the fixing frame. The adjusting component includes a dovetail groove, which is formed on the surface of the mounting frame. A dovetail block is slidably connected to the surface of the dovetail groove. An adjusting plate is fixedly connected to the surface of the dovetail block, and an auxiliary roller is rotatably connected to the surface of the adjusting plate.

[0007] Furthermore, a turntable is fixedly connected to the top surface of the screw, and a handle is fixedly connected to the surface of the turntable.

[0008] Furthermore, the surface of the mounting frame is provided with a clearance groove, which matches the turntable.

[0009] Furthermore, the number of dovetail grooves, dovetail blocks, adjusting plates, and auxiliary rollers is four groups, and the number of auxiliary rollers in each group is multiple and evenly distributed.

[0010] Furthermore, the auxiliary component includes a soft pad, which is fixedly connected to the surface of the mounting frame, and the soft pad consists of two sets arranged symmetrically.

[0011] Furthermore, a second soft pad is fixedly connected to the top surface of the fixed frame, and the number of the second soft pads is two sets, which are arranged symmetrically.

[0012] Furthermore, a rubber ring is fixedly connected to the surface of the auxiliary roller, and the auxiliary roller is provided with different specifications.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a loading and unloading device, firstly, select the auxiliary roller of the corresponding specification according to the width of the circuit board body, slide it into the dovetail block along the dovetail groove, and use the adjusting plate to install the auxiliary roller on the mounting frame. Then, insert the circuit board body into the mounting frame. During this process, the auxiliary roller can not only limit the circuit board body, but also make the circuit board body quickly and smoothly inserted. After insertion, use the relief groove to hold the handle, rotate the turntable to make the screw rotate, and drive the fixing frame upward along the limiting rod. Circuit boards of different thicknesses can be fixed between the soft pad one on the mounting frame and the soft pad two on the fixing frame. At the same time, the ventilation groove facilitates heat dissipation. When disassembly is required, simply reverse the screw to make the fixing frame downward along the limiting rod. After releasing the circuit board body, first use your hand to hold the adjusting plate to prevent it from falling off the mounting frame, and then use your hand to pull out the circuit board body. Similarly, the auxiliary roller makes the disassembly process of the circuit board body relatively quick and smooth.

[0015] 2. In this utility model, by setting up a loading and unloading device, the ultra-long circuit board body with different thicknesses and widths can be loaded, unloaded and fixed quickly and effortlessly. At the same time, it avoids the bottom of the circuit board body from directly contacting the mounting frame, making it easier for heat to dissipate, thus effectively improving the convenience of the equipment.

[0023] Please see Figures 1-5 This utility model provides a technical solution: an ultra-long LED printed circuit board, including a mounting frame 1, a circuit board body 2 and a loading and unloading device 3. The circuit board body 2 is disposed inside the mounting frame 1, and the loading and unloading device 3 is disposed on the surface of the mounting frame 1.

[0024] The specific setup and function of its loading and unloading device 3 will be explained below.

[0025] In this embodiment: the loading and unloading device 3 includes a fixing component 31, an adjusting component 32, and an auxiliary component 33. The fixing component 31 includes a screw 311, which is rotatably connected to the inner wall of the mounting frame 1. A fixing frame 312 is threadedly connected to the surface of the screw 311. A limit rod 313 is fixedly connected to the surface of the mounting frame 1. The fixing frame 312 is slidably connected to the surface of the limit rod 313. A ventilation groove 314 is provided on the surface of the fixing frame 312. The adjusting component 32 includes a dovetail groove 321, which is opened on the surface of the mounting frame 1. A dovetail block 322 is slidably connected to the surface of the dovetail groove 321. An adjusting plate 323 is fixedly connected to the surface of the dovetail block 322. An auxiliary roller 324 is rotatably connected to the surface of the adjusting plate 323.

[0026] The effects achieved by the above components are as follows: rotating the screw 311 causes the fixing frame 312 to slide up and down along the limiting rod 313, which can fix the circuit board body 2 of different thicknesses between the mounting frame 1 and the fixing frame 312, and avoid the bottom of the circuit board body 2 from being in complete contact with the mounting frame 1, which would affect heat dissipation. The ventilation groove 314 is set to facilitate the heat dissipation of the bottom of the circuit board body 2. The dovetail groove 321 and dovetail block 322 are set to facilitate the quick loading and unloading of the adjusting plate 323, and also to ensure that the adjusting plate 323 can only be separated from the mounting frame 1 in one direction. The adjusting plate 323 and the auxiliary roller 324 are set to limit the circuit board body 2, and also to allow the circuit board body 2 to be inserted quickly and smoothly.

[0027] Specifically, a turntable 316 is fixedly connected to the top surface of the screw 311, and a handle 317 is fixedly connected to the surface of the turntable 316.

[0028] The effects achieved by the above components are as follows: the turntable 316 is provided to facilitate the rotation of the screw 311, and the handle 317 is provided to facilitate the gripping of the turntable 316.

[0029] Specifically, the surface of the mounting frame 1 is provided with a clearance groove 315, which matches the turntable 316.

[0030] The effect achieved by the above components is as follows: the clearance groove 315 is provided to facilitate the placement of the turntable 316 and to prevent the turntable 316 from protruding from the top surface of the mounting frame 1, which would affect normal installation and use.

[0031] Specifically, there are four sets of dovetail grooves 321, dovetail blocks 322, adjusting plates 323 and auxiliary rollers 324, with multiple auxiliary rollers 324 in each set and evenly distributed.

[0032] The effect achieved by the above components is as follows: setting four sets of auxiliary rollers 324 is to facilitate the limiting and fixing of the four corners of the circuit board body 2, and each set of auxiliary rollers 324 consists of multiple rollers to increase the contact area between the circuit board body 2 and the auxiliary rollers 324.

[0033] Specifically, the auxiliary component 33 includes a soft pad 331, which is fixedly connected to the surface of the mounting frame 1. There are two sets of soft pads 331 arranged symmetrically.

[0034] The effect achieved by the above components is as follows: the soft pad 331 is set to avoid damage caused by hard contact between the circuit board body 2 and the mounting frame 1.

[0035] Specifically, the top surface of the fixed frame 312 is fixedly connected with a second soft pad 332, and there are two sets of the second soft pad 332 arranged symmetrically.

[0036] The effect achieved by the above components is as follows: the soft pad 332 is set to avoid the circuit board body 2 from making hard contact with the fixing frame 312, which would cause damage to it.

[0037] Specifically, a rubber ring 333 is fixedly connected to the surface of the auxiliary roller 324, and the auxiliary roller 324 is provided with different specifications.

[0038] The effects achieved by the above components are as follows: the rubber ring 333 is set so as not to affect the auxiliary roller 324's auxiliary role in the movement process when inserting the circuit board body 2, and also to avoid the situation where the auxiliary roller 324 and the circuit board body 2 make hard contact and cause damage. The auxiliary roller 324 of different specifications is set so as to facilitate the corresponding selection according to the width of the circuit board body 2. Four sets of auxiliary rollers 324 can be used to limit and clamp circuit board bodies 2 of different widths.

[0039] Working principle: By setting up the loading and unloading device 3, the auxiliary roller 324 of the corresponding specification is first selected according to the width of the circuit board body 2. It slides into the dovetail block 322 along the dovetail groove 321. The auxiliary roller 324 is installed on the mounting frame 1 using the adjusting plate 323. Then, the circuit board body 2 is inserted into the mounting frame 1. During this process, the auxiliary roller 324 can both limit the circuit board body 2 and enable the circuit board body 2 to be inserted quickly and smoothly. After insertion, the handle 317 is gripped by the relief groove 315, and the turntable 316 is rotated to make the screw 311 rotate, driving the screw 311 to rotate. The fixing frame 312 moves upward along the limiting rod 313, which can fix the circuit board body 2 of different thicknesses between the soft pad 331 on the mounting frame 1 and the soft pad 332 on the fixing frame 312. At the same time, the ventilation groove 314 facilitates heat dissipation. When disassembly is required, simply reverse the screw 311 to make the fixing frame 312 move downward along the limiting rod 313. After releasing the circuit board body 2, first hold the adjusting plate 323 with your hand to prevent it from falling off the mounting frame 1, and then pull out the circuit board body 2 by hand. Similarly, the auxiliary roller 324 makes the disassembly process of the circuit board body 2 faster and smoother.

[0040] By setting up the loading and unloading device 3, the extra-long circuit board body 2 of different thicknesses and widths can be loaded, unloaded and fixed quickly and effortlessly. At the same time, it avoids the bottom of the circuit board body 2 from directly contacting the mounting frame 1, making it easier for heat to dissipate, thus effectively improving the convenience of the equipment.
