Description

Technical Field

[0001] This utility model relates to the field of PCB boards, and in particular to a novel stepless dimming PCB board for a rechargeable mushroom touch lamp. Background Technology

[0002] This new rechargeable mushroom-shaped touch light features a stepless dimming PCB board that integrates touch control and charging functionality. Stepless dimming is achieved through a simple touch, allowing for customized brightness. Fitted to the mushroom light shape, its stable built-in circuitry drives LED beads, creating diverse atmospheres for indoor and outdoor lighting – practical and convenient.

[0003] Existing stepless dimming PCB boards for new rechargeable mushroom touch lamps typically use screws to screw the PCB board onto the lamp base. Tightening the screws is time-consuming, and since the screws are small, the force must be controlled when tightening them. Improper force may strip the screw threads and damage the screw holes in the lamp base, making subsequent repairs and replacements very troublesome. Utility Model Content

[0004] In view of this, the present invention provides a novel rechargeable mushroom touch lamp stepless dimming PCB board. The main technical problem to be solved is that: usually, the PCB board is screwed onto the lamp base with screws. Tightening the screws is time-consuming, and the screws are small. When tightening them, the force must be controlled. Improper force may cause the screws to strip and may also damage the screw holes of the lamp base, making subsequent repair and replacement very troublesome.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a novel rechargeable mushroom touch lamp stepless dimming PCB board, including a mounting plate, an mounting groove on the upper surface of the mounting plate, a turntable movably mounted on the inner surface of the mounting groove, four inclined grooves on the upper surface of the turntable, four movable grooves on the inner bottom of the mounting groove, a spring fixedly connected to the inner wall of the movable groove, a locking block fixedly connected to one end of the spring, a locking pin fixedly connected to the upper surface of the locking block, the locking pin being located inside the inclined groove, a fixing component above the mounting plate, and a PCB board inside the fixing component.

[0006] By adopting the above technical solution, the PCB board can be installed on the lamp base by combining the fixing components and the mounting plate, which saves more time, avoids the trouble caused by stripped screws, and is more convenient.

[0007] As a further description of the above technical solution:

[0008] The fixing component includes a longitudinal baffle. The upper surface of the mounting plate is fixedly connected to the longitudinal baffle. There are two longitudinal baffles. A transverse baffle is fixedly connected between two adjacent longitudinal baffles. The side wall of the longitudinal baffle is provided with a limiting groove. The PCB board is located between adjacent limiting grooves.

[0009] By adopting the above technical solution, the longitudinal baffle and the transverse baffle together form a limiting frame. With the help of the limiting groove, the PCB board can be well restricted within the limiting frame, preventing the PCB board from moving up and down, forward and backward, or to the right.

[0010] As a further description of the above technical solution:

[0011] A fixed shaft is fixedly connected to the side wall of the longitudinal baffle. A limit block is movably installed on the outer surface of the fixed shaft. A limit plate is fixedly connected to the end of the fixed shaft away from the longitudinal baffle. A fixed plate is fixedly connected to the side wall of the longitudinal baffle.

[0012] By adopting the above technical solution, when the limiting block rotates around the fixed axis until its lower surface is in contact with the upper surface of the fixed plate, the PCB board cannot move to the left, thereby locking the PCB board in all directions and making it impossible for the PCB board to move. When it is necessary to remove the PCB board, it is only necessary to rotate the limiting block so that the limiting block no longer obstructs the movement of the PCB board.

[0013] As a further description of the above technical solution:

[0014] The upper surface of the turntable is fixedly connected with two actuating columns.

[0015] By adopting the above technical solution, the actuating column can more easily rotate the turntable, providing a point of leverage for rotating the turntable.

[0016] As a further description of the above technical solution:

[0017] A lamp base is provided below the mounting plate, and the inner surface of the lamp base has four slots.

[0018] By adopting the above technical solution, the lamp base is part of the new rechargeable mushroom touch lamp base, and the slot is used to dock with the card block. When the card block enters the slot, the installation plate cannot be moved.

[0019] As a further description of the above technical solution:

[0020] The upper surface of the lamp base is provided with positioning grooves, and there are four positioning grooves. The outer surface of the mounting plate is fixedly connected with positioning blocks, and there are four positioning blocks, which are located inside the positioning grooves.

[0021] By adopting the above technical solution, the purpose of the positioning groove and the positioning block working together is to provide positioning for the installation plate to be installed on the lamp base, so as to avoid misalignment between the groove and the block after installation.

[0022] By employing the above technical solution, the novel rechargeable mushroom touch lamp stepless dimming PCB board of this utility model has at least the following beneficial effects:

[0023] Compared with existing technologies, this novel rechargeable mushroom touch lamp stepless dimming PCB board comprises a mounting plate, a turntable, an inclined groove, a moving groove, a spring, a locking block, a locking pin, a PCB board, a fixing component, a toggle post, a locking slot, a lamp base, a positioning groove, and a positioning block. When the PCB board needs to be placed into the lamp base, it is first fixed to the fixing component. Then, the positioning block is aligned with the positioning slot. The mounting plate is lowered, and during this downward movement, the toggle post is rotated counterclockwise, causing the turntable to rotate counterclockwise. This causes the locking pin to move along the inclined groove, bringing the four locking pins and locking blocks closer together, compressing the spring. When the locking block is fully retracted into the moving groove, the mounting plate can continue to move downwards until it can no longer move. At this point, the toggle post is released, and the locking blocks align with the locking slots, releasing the spring. The rebound causes the four locking blocks and pins to move away from each other, and then the locking blocks enter the slots. At this time, the mounting plate is fixed, which is equivalent to fixing the PCB board. When it is necessary to remove the PCB board, simply repeat the above operation to make the locking blocks retract into the moving slots. Compared with existing PCB boards, which are usually screwed onto the lamp base with screws, this new type of rechargeable mushroom touch lamp stepless dimming PCB board can use a combination of fixing components and mounting plates to install the PCB board onto the lamp base, which saves more time and avoids the trouble caused by stripped screws, making subsequent repairs and replacements very troublesome.

[0024] Compared to existing technologies, this novel rechargeable mushroom-shaped touch light's stepless dimming PCB board, through the PCB board and fixing components, and the vertical and horizontal baffles forming a limiting frame, effectively confines the PCB board within the limiting frame, preventing it from moving up and down, forward and backward, or to the right. When the limiting block rotates around the fixing axis until its lower surface aligns with the upper surface of the fixing plate, it prevents the PCB board from moving to the left, thus locking the PCB board in all directions and making it impossible to move. To remove the PCB board, simply rotate the limiting block until it no longer obstructs its movement. Attached Figure Description

[0034] Reference Figure 1-7The novel rechargeable mushroom touch lamp stepless dimming PCB board provided by this utility model includes a mounting plate 1. A mounting groove 2 is formed on the upper surface of the mounting plate 1. A turntable 3 is movably mounted on the inner surface of the mounting groove 2. Four inclined grooves 4 are formed on the upper surface of the turntable 3. Four movable grooves 5 are formed at the bottom inner surface of the mounting groove 2. A spring 6 is fixedly connected to the inner wall of each movable groove 5. A locking block 7 is fixedly connected to one end of each spring 6. A locking pin 8 is fixedly connected to the upper surface of the locking block 7 and is located inside the inclined groove 4. A fixing component 10 is provided above the mounting plate 1. A PCB board 9 is disposed inside the fixing component 10. When the PCB board 9 needs to be placed into the lamp base 12, the PCB board 9 is first fixed to the fixing component 10. The mounting plate 1 is then aligned with the positioning block 15 and the positioning groove 14. The mounting plate 1 is lowered, and during this downward movement, the actuating column 11 is rotated counterclockwise, causing the turntable 3 to rotate counterclockwise. This causes the locking pins 8 to move along the inclined groove 4, bringing the four locking pins 8 and locking blocks 7 closer together. The spring 6 is compressed. When the locking block 7 is fully retracted into the moving groove 5, the mounting plate 1 can continue to move downwards until it can no longer move. The actuating column 11 is then released, aligning the locking blocks 7 with the locking groove 13. The spring 6 rebounds, causing the four locking blocks 7 and locking pins 8 to move away from each other, and the locking blocks 7 enter the locking groove 13. At this point, the mounting plate 1 is fixed, which is equivalent to fixing the PCB board 9. When the PCB board 9 needs to be removed, the above operation is repeated to retract the locking blocks 7. The PCB board 9 can be placed in the moving slot 5. The fixing component 10 includes a longitudinal baffle 101. The upper surface of the mounting plate 1 is fixedly connected to the longitudinal baffle 101. There are two longitudinal baffles 101. A transverse baffle 103 is fixedly connected between two adjacent longitudinal baffles 101. The side wall of the longitudinal baffle 101 is provided with a limiting slot 102. The longitudinal baffle 101 and the transverse baffle 103 together form a limiting frame. With the help of the limiting slot 102, the PCB board 9 can be well restricted within the limiting frame, so that the PCB board 9 cannot move up and down, forward and backward, or to the right. The PCB board 9 is located between adjacent limiting slots 102. A fixing shaft 104 is fixedly connected to the side wall of the longitudinal baffle 101. A limit block 106 is movably installed on the outer surface of the fixing shaft 104. A limiting plate 105 is fixedly connected to the end of shaft 104 away from the longitudinal baffle 101. When the limiting block 106 rotates around the fixed shaft 104 until its lower surface is in contact with the upper surface of the fixed plate 107, it prevents the PCB board 9 from moving to the left, thus locking the PCB board 9 in all directions and preventing it from moving. When it is necessary to remove the PCB board 9, it is only necessary to rotate the limiting block 106 so that the limiting block 106 no longer obstructs the movement of the PCB board 9. The fixed plate 107 is fixedly connected to the side wall of the longitudinal baffle 101. A toggle post 11 is fixedly connected to the upper surface of the turntable 3. Toggle the toggle post 11 to make it easier to rotate the turntable 3 and provide a force point for rotating the turntable 3. There are two toggle posts 11. A lamp base 12 is provided below the mounting plate 1.The inner surface of the lamp base 12 has slots 13. The lamp base 12 is part of the base of this new type of rechargeable mushroom touch lamp. The slots 13 are used to mate with the card block 7. When the card block 7 enters the slots 13, the mounting plate 1 cannot be moved. There are four slots 13.

[0035] The upper surface of the lamp base 12 is provided with positioning grooves 14, and there are four positioning grooves 14. The outer surface of the mounting plate 1 is fixedly connected with positioning blocks 15, and there are four positioning blocks 15. The purpose of the positioning grooves 14 and positioning blocks 15 is to provide positioning for the mounting plate 1 to be installed on the lamp base 12, so as to avoid the slot 13 and the block 7 not aligning after installation. The positioning blocks 15 are located inside the positioning grooves 14.

[0036] Working principle: When the PCB board 9 needs to be placed into the lamp base 12, first fix the PCB board 9 on the fixing component 10, then align the positioning block 15 with the positioning groove 14, move the mounting plate 1 down and rotate the actuating column 11 counterclockwise during the downward movement, which in turn drives the turntable 3 to rotate counterclockwise, which in turn drives the locking pin 8 to move along the inclined groove 4, which in turn drives the four locking pins 8 and locking blocks 7 to move closer to each other, and the spring 6 is compressed. When the locking block 7 is fully retracted into the moving groove 5, the mounting plate 1 can continue to move down until it can no longer move. Release the actuating column 11, the locking block 7 is aligned with the locking groove 13, the spring 6 rebounds and drives the four locking blocks 7 and locking pins 8 to move away from each other, and then the locking block 7 enters the locking groove 13. At this time, the mounting plate 1 is fixed, which is equivalent to fixing the PCB board 9. When it is necessary to remove the PCB board 9, simply repeat the above operation to make the locking block 7 retract into the moving groove 5.
