Description

Technical Field

[0001] The utility model relates to the technical field of electronic processing and production, in particular to a LED circuit board fixing device. Background Art

[0002] The LED circuit board fixture is a mechanical device specially used to fix and protect the LED circuit board. It provides a stable installation base to prevent the LED circuit board from shifting or being damaged due to vibration, collision and other factors during use.

[0003] The existing patent CN215500121U discloses a fixing device for an LED circuit board. Previously, a hole was directly opened on the LED circuit board body and then fixed with screws. This easily caused damage to the LED circuit board body when the hole was opened, which increased the cost. Now, the LED circuit board body is installed inside the installation frame, and the installation frame protects the LED circuit board body to avoid damage to the LED circuit board body during installation and disassembly. At the same time, the installation frame is clamped through the first slot, and then the bolt is passed through the installation hole and threadedly connected to the positioning hole, so that the installation frame is fixed inside the fixing seat, which solves the problem that the existing LED circuit board body is inconvenient to disassemble during maintenance, has the advantage of easy disassembly, is convenient for users to use, and also avoids damage to the LED circuit board body caused by disassembly, thereby improving the practicality of the LED circuit board body.

[0004] The above technical solution sets up a mounting frame, and installs the LED circuit board inside the mounting frame. While protecting the LED circuit board, the first card slot is engaged with the mounting frame, and then the mounting frame and the fixing seat are fixed, thereby solving the problem that the existing LED circuit board body is inconvenient to disassemble during maintenance.

[0005] However, in actual use, the following deficiencies still exist. For example, the LED circuit board is installed inside the fixing base through the mounting frame. Since no shock-absorbing structure is installed between the LED circuit board and the mounting frame, when the fixing base vibrates, the force generated by the vibration will be transmitted to the LED circuit board through the mounting frame, which may cause damage to the LED circuit board, which is not conducive to improving the stability of the fixing device, nor is it conducive to improving the service life of the LED circuit board. Therefore, the utility model proposes an LED circuit board fixing device. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and provide an LED circuit board fixing device.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: an LED circuit board fixing device, comprising a base, a fixing component is arranged on the base, a clamping component is arranged on one end of the fixing component away from the base, and a supporting component is arranged on one end of the fixing component close to the base;

[0008] The fixing assembly includes a support rod and a fixing block, the support rod is arranged on both sides of the top of the base, the support rod is fixedly connected to a limiting plate, one end of the support rod close to the limiting plate is sleeved with a spring sheet, the top end of the support rod is fixedly connected to the limiting block, and the fixing block is movably inserted into one end of the support rod close to the limiting block;

[0009] The clamping assembly comprises a sliding rod and a sleeve, wherein the sleeve is fixedly connected to a fixed block, the sliding rod is slidably connected inside the sleeve, and the sliding rod and the sleeve are fixedly connected to a clamping block on one side away from each other.

[0010] As a preferred implementation, a clamping groove is provided on one side of the support rod close to the limit block, and an elastic column is movably inserted on one side of the support rod close to the clamping groove.

[0011] The technical effect of adopting the above technical solution is to ensure that the limit block continuously clamps the LED circuit board on the support rod to prevent the LED circuit board from falling off the fixing device.

[0012] As a preferred embodiment, the support assembly includes a connecting member and a support plate, the connecting member is fixedly connected to one end of the support rod close to the base, the top of the connecting member is fixedly connected to a damping telescopic rod, the support plate is fixedly connected to one end of the damping telescopic rod away from the connecting member, the damping telescopic rod is sleeved with a spring 2, and the spring 2 is fixedly connected to the connecting member and the support plate.

[0013] The technical effect of adopting the above technical solution is that spring 2 and the damping telescopic rod cooperate with the force generated by the buffer base to avoid insufficient support force at the bottom of the LED circuit board and the vibration generated by the base causing the LED circuit board to fold, thereby further improving the stability of the fixing device and the service life of the LED circuit board.

[0014] As a preferred implementation, a soft pad is fixedly connected to a side of the support plate away from the damping telescopic rod.

[0018] As a preferred embodiment, there are two connecting members arranged on the base, and a telescopic block is fixedly connected between the two connecting members.

[0019] The technical effect of adopting the above technical solution is that the fixing device can be adapted to LED circuit boards of different widths, thereby further increasing the versatility of the fixing device.

[0020] Compared with the prior art, the advantages and positive effects of the utility model are:

[0021] 1. By setting a fixing component and a clamping component, the LED circuit board is inserted into the clamping block, and the fixing block is pushed. The fixing block drives the clamping block and the LED circuit board to move through the sliding rod and the sleeve, so that the fixing block passes through the limit block and clamps with the support rod, and is connected with the spring piece in a transmission manner. In this way, the LED circuit board is fixed on the support rod. This design can not only quickly install and fix the LED circuit board, but also solve the problem of lack of buffer structure between the LED circuit board and the base through the spring piece. When the base vibrates, the fixing device can buffer the force generated by the base through the spring piece, reduce the impact of vibration on the LED circuit board, and avoid damage to the LED circuit board due to vibration. This is conducive to improving the stability of the fixing device and extending the service life of the LED circuit board.

[0022] 2. By setting a support component, by welding the connecting piece to the base, and installing a support plate on the damping telescopic rod, the support plate can support the bottom of the LED circuit board. At the same time, a second spring is installed between the support plate and the connecting piece. When the base vibrates, the support plate and the damping telescopic rod work together to support the bottom of the LED circuit board. The second spring is used in conjunction with the damping telescopic rod to buffer the force generated by the base. This design can avoid insufficient support force at the bottom of the LED circuit board and prevent the vibration generated by the base from causing the LED circuit board to fold, thereby further improving the stability of the fixing device and the service life of the LED circuit board.

[0033] 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.

[0034] like Figure 1 - Figure 5 As shown, this embodiment provides a technical solution: an LED circuit board fixing device, comprising a base 1, a fixing component 2 is arranged on the base 1, a clamping component 3 is arranged on the end of the fixing component 2 away from the base 1, and a supporting component 4 is arranged on the end of the fixing component 2 close to the base 1;

[0035] like Figure 2 As shown, the fixing assembly 2 includes a support rod 21 and a fixing block 22. The support rod 21 is arranged on both sides of the top of the base 1. The support rod 21 is fixedly connected to a limiting plate 26. One end of the support rod 21 close to the limiting plate 26 is sleeved with a spring piece 24. The top of the support rod 21 is fixedly connected to the limiting block 23. The fixing block 22 is movably inserted at one end of the support rod 21 close to the limiting block 23.

[0036] like Figure 1 and Figure 3 As shown, the clamping assembly 3 includes a slide bar 31 and a sleeve 32, the sleeve 32 is fixedly connected to the fixed block 22, the slide bar 31 is slidably connected to the inside of the sleeve 32, and the slide bar 31 and the sleeve 32 are fixedly connected to the clamping block 33 on the side away from each other. By welding the limiting plate 26 on the support rod 21, and sleeve 24 is set between the limiting plate 26 and the limiting block 23, then the LED circuit board is inserted into the inside of the clamping block 33, and the fixed block 22 is pushed. The fixed block 22 drives the clamping block 33 and the LED circuit board to move through the slide bar 31 and the sleeve 32, so that the fixed block 22 passes through the limit block 23 and is clamped with the support rod 21, and is connected with the spring piece 24 in a transmission manner, so that the LED circuit board is fixed on the base 1. In this way, not only can the LED circuit board be installed and fixed quickly, but also the spring piece 24 solves the problem of no buffer structure between the LED circuit board and the base 1. When the base 1 vibrates, the fixing device buffers the force generated by the base 1 through the spring piece 24, thereby reducing the impact of the vibration on the LED circuit board, avoiding damage to the LED circuit board due to vibration, which is beneficial to improving the stability of the fixing device and increasing the service life of the LED circuit board.

[0037] Furthermore, if Figure 2 As shown, a snap-in groove 27 is provided on one side of the support rod 21 near the limit block 23, and an elastic column 25 is movably inserted on one side of the support rod 21 near the snap-in groove 27. When the LED circuit board is installed on the support rod 21, the elastic column 25 is inserted into the inside of the snap-in groove 27, so that the snap-in groove 27 remains in a state of being stretched open by the elastic column 25, thereby ensuring that the limit block 23 continuously snaps the LED circuit board onto the support rod 21 to prevent the LED circuit board from falling off from the fixing device.

[0038] In order to solve the problem of insufficient support at the bottom of the LED circuit board, such as Figure 4 - Figure 5As shown, the support assembly 4 includes a connecting piece 41 and a supporting plate 43. The connecting piece 41 is fixedly connected to one end of the supporting rod 21 close to the base 1. A damping telescopic rod 46 is fixedly connected to the top of the connecting piece 41. The supporting plate 43 is fixedly connected to one end of the damping telescopic rod 46 away from the connecting piece 41. A spring 2 42 is sleeved on the damping telescopic rod 46. The spring 2 42 is fixedly connected to the connecting piece 41 and the supporting plate 43. By welding the connecting piece 41 to the base 1 and installing the supporting plate 43 on the damping telescopic rod 46, the supporting plate 43 supports the bottom of the LED circuit board, and the spring 2 42 is installed between the supporting plate 43 and the connecting piece 41. When the base 1 vibrates, the supporting plate 43 cooperates with the damping telescopic rod 46 to support the bottom of the LED circuit board. The spring 2 42 cooperates with the damping telescopic rod 46 to buffer the force generated by the base 1, so as to avoid insufficient support force at the bottom of the LED circuit board and the vibration generated by the base 1 folding the LED circuit board, thereby further improving the stability of the fixing device and the service life of the LED circuit board.

[0039] Furthermore, if Figure 4 As shown, a soft pad 44 is fixedly connected to the side of the support plate 43 away from the damping telescopic rod 46. By installing the soft pad 44 between the LED circuit board and the support plate 43, direct contact between the support plate 43 and the LED circuit board is avoided, thereby preventing the support plate 43 from damaging the LED circuit board.

[0040] Furthermore, if Figure 3 As shown, a spring 34 is fixedly connected between the inner wall of the sleeve 32 and the slide bar 31. By installing the spring 34, when the slide bar 31 is pulled and the sleeve 32 cooperates with the clamping block 33 to clamp the LED circuit board, the force generated by the spring 34 makes the spring 34 clamped with the LED circuit board more tightly, avoiding looseness between the slide bar 31 and the sleeve 32, causing the LED circuit board to slip off the fixing device, and allowing the slide bar 31 and the sleeve 32 to adapt to LED circuit boards of different lengths, thereby increasing the versatility of the fixing device.

[0041] Furthermore, if Figure 4 As shown, there are two connecting members 41 arranged on the base 1, and a telescopic block 45 is fixedly connected between the two connecting members 41. The distance between the two connecting members 41 is adjusted by the telescopic block 45, and the connecting members 41 are then welded to the base 1, so that the fixing device can adapt to LED circuit boards of different widths, further increasing the versatility of the fixing device.

[0042] Working principle: Figure 1 - Figure 5 As shown:

[0043] When in use: first pull the connecting piece 41, adjust the distance between the two connecting pieces 41 to the specified length through the telescopic block 45, and then weld the connecting piece 41 to the base 1, then pull the slide bar 31 to make the slide bar 31 slide inside the sleeve 32, and stretch the spring 1 34 to make the clamping block 33 match the length of the LED circuit board, and insert the LED circuit board into the clamping block 33. At this time, the spring 1 34 is tightened to fix the LED circuit board, and then push the fixing block 22, the fixing block 22 passes through the slide bar 31 and the sleeve 32, drive the clamping block 33 and the LED circuit board to move, so that the fixing block 22 passes through the limiting block 23 and is clamped with the support rod 21, and is connected with the spring piece 24 in transmission, so that the LED circuit board is fixed on the fixing device, and the bottom of the LED circuit board is attached to the soft pad 44, so that the support plate 43 supports the bottom of the LED circuit board, and then the elastic column 25 is inserted into the inside of the clamping groove 27, so that the clamping groove 27 remains in a state of being stretched open by the elastic column 25, thereby ensuring that the limiting block 23 continuously clamps the LED circuit board on the support rod 21.

[0044] When the base 1 vibrates, the spring 24 on the support rod 21 cooperates with the damping telescopic rod 46 and the spring 2 42 to buffer the vibration of the base 1, thereby preventing the LED circuit board from being damaged due to vibration and improving the stability of the fixing device and the service life of the LED circuit board.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
