The emergence of folding desk lamps is precisely to meet people's needs for higher performance and more functions of desk lamps.
[0003] Traditional folding desk lamps typically rely on a simple base for support. Due to the limited space on a desk, they can easily tip over in complex environments, such as when students are studying and frequently touching books or stationery. Similarly, when office workers are busy, the movement of their arms can cause the lamp to wobble or even fall. A tipped lamp can damage not only the lamp itself but also surrounding objects, affecting normal use and causing considerable inconvenience. Therefore, a folding desk lamp is proposed to address these issues. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0033] Reference Figure 1 - Figure 3This utility model provides an embodiment of a folding desk lamp, including a base 1, which serves as the basic support structure for the lamp. The base 1 provides a stable placement surface for the entire lamp, allowing it to be placed stably on the desk. A folding frame 2 is provided on the upper part of the base 1. The main function of the folding frame 2 is to enable the lamp to fold. When the lamp is not in use, it can be folded using the folding frame 2, effectively reducing the space occupied by the lamp and facilitating storage and carrying. A support frame 3 is provided on the upper part of the folding frame 2 to support the lampshade 4. Two sets of lampshades 4 are rotatably connected to the outer side of the support frame 3, arranged symmetrically. The lampshade 4 can control the direction and range of light illumination, thereby improving the lighting effect and meeting the user's lighting needs in different scenarios. A support mechanism is provided at the lower part of the base 1, including a fixing... The components and limiting components, the fixing components include a base plate 51, a support plate 52 and a suction cup 53 fixed to the base plate 51 to realize the function of fixing the desk lamp. The support plate 52 is fixedly connected to the lower part of the base plate 51. The support plate 52 connects the base plate 51 and the suction cup 53, and plays the role of transmitting pressure and support. When fixing the desk lamp, it transmits the pressure of the base plate 51 to the suction cup 53 to ensure that the suction cup 53 can be tightly attached to the desk, realize the stable placement of the desk lamp, effectively prevent the desk lamp from tipping over due to accidental touch, and ensure the stability of the desk lamp during use. The lower part of the support plate 52 is provided with suction cups 53. Multiple sets of suction cups 53 are evenly arranged under the base plate 51. The suction cups 53 form negative pressure by expelling the internal air, and tightly attach to the desktop, thereby fixing the desk lamp and preventing it from tipping over due to accidental touch during use.
[0034] Reference Figure 3 - Figure 5 The inner wall of the base plate 51 has a channel 54, which is connected to the support plate 52 and the suction cup 53, providing a passage for air to escape. When the suction cup 53 is squeezed and the piston 57 is pulled, air enters the slide groove 56 through the channel 54, realizing the suction function of the suction cup 53. The middle of the base plate 51 has a slide groove 56, which is connected to the channel 54. The inner wall of the slide groove 56 is connected to the piston 57. When the connecting rod 55 is pulled, the piston 57 slides in the slide groove 56, sucking up the air in the suction cup 53 and reducing the pressure in the suction cup 53. By controlling the external position of the piston 57, the suction and release of the suction cup 53 can be realized. The connecting rod 55 is fixedly connected to the rear side of the piston 57. By pulling or pushing the connecting rod 55, the piston 57 is moved in the slide groove 56, thereby controlling the suction and release of the suction cup 53, which is convenient for user operation. The connecting rod 55 is slidably connected to the inner wall of the base plate 51.
[0035] Reference Figure 3 and Figure 4The limiting component includes a connector 61, the upper part of which is protruding and slides on the inner wall of the base plate 51. The protruding design of the upper part can cooperate with the slot 63 to restrict the movement of the connecting rod 55, thereby fixing the suction cup 53 in the adsorption state and ensuring that the table lamp is fixed firmly. The connector 61 is rotatably connected to the rear side of the connecting rod 55 and slides on the inner wall of the base plate 51. A pull rod 62 is fixedly connected to the rear side of the connector 61. The rear side is L-shaped, which makes it convenient for users to pull and rotate the connector 61 to realize the limiting and releasing operation of the connecting rod 55, and facilitates the control of the adsorption and release of the suction cup 53. The inner wall of the base plate 51 has a slot 63. The pull rod 62 drives the connector 61 to rotate 90 degrees and insert it into the slot 63, thereby limiting the piston 57.
[0036] Reference Figure 6 and Figure 7 The inner wall of the lampshade 4 is provided with a rotating assembly, which includes a pressing rod 71. By pressing the pressing rod 71, the position of the limiting plate 72 and the limiting ball 74 can be controlled, realizing the rotation and angle adjustment of the lampshade 4. The pressing rod 71 slides on the inner wall of the lampshade 4 and the support frame 3. The lower part of the pressing rod 71 is fixedly connected to the limiting plate 72. When the pressing rod 71 is pressed, the limiting plate 72 compresses the spring 73 and moves downward, causing the limiting ball 74 to disengage from the limiting groove 75, so that the lampshade 4 can be rotated. The limiting plate 72 slides on the inner wall of the lampshade 4. The lower part of the limiting plate 72 is elastically connected to the inner wall of the lampshade 4 through the compression spring 73, connecting the lower part of the limiting plate 72 and the inner wall of the lampshade 4, providing an upward elastic force to the limiting plate 72. After releasing the pressing rod 71, the limiting plate 72 is reset, causing the limiting ball 74 to re-enter the limiting groove 75, fixing the angle of the lampshade 4.
[0037] Furthermore, a limiting ball 74 is provided on the upper part of the limiting plate 72, and a limiting groove 75 is provided on the lower part of the support frame 3. The upper part of the limiting ball 74 is set as an arc surface. The limiting ball 74 is inserted into the inner wall of the limiting groove 75. When the limiting ball 74 is inserted into the limiting groove 75, the angle of the lampshade 4 can be fixed. Pressing the pressing rod 71 makes the limiting ball 74 disengage from the limiting groove 75, and the lampshade 4 can be rotated to adjust the angle. Multiple sets of limiting balls 74 and limiting grooves 75 are provided. The multiple sets of limiting balls 74 and limiting grooves 75 are distributed in a circumferential array around the center point of the pressing rod 71, which can increase the stability of limiting the angle of the lampshade 4.
[0038] Working principle: When in use, place the base 1 on the desk and pull the lever 62 to drive the piston 57 to slide in the slide groove 56. Since the channel 54 is connected to the inside of the slide groove 56, the piston 57 will suck up the air in the suction cup 53 when it slides, which will reduce the pressure in the suction cup 53. The air enters the slide groove 56 through the channel 54, and multiple sets of suction cups 53 begin to expel the internal air.
[0039] When the air inside the suction cup 53 is expelled to a certain extent, the pull rod 62 is rotated, which drives the connector 61 to rotate 90 degrees. The upper protrusion of the connector 61 engages with the slot 63 on the inner wall of the base plate 51 and is inserted into the slot 63, restricting the movement of the connecting rod 55 and thus fixing the position of the piston 57 to prevent air backflow. At this time, because the internal pressure of the suction cup 53 is lower than the external atmospheric pressure, a negative pressure is formed, and it is tightly attached to the table, so as to achieve stable placement of the table lamp and prevent it from tipping over due to accidental touch.
[0040] If it is necessary to adjust the angle of the lampshade 4, press the pressing rod 71. The pressing rod 71 slides on the inner wall of the lampshade 4 and the support frame 3. The limiting plate 72 fixedly connected to its lower part moves downward, compressing the compression spring 73. The limiting ball 74 on the upper part of the limiting plate 72 disengages from the limiting groove 75 at the lower part of the support frame 3, releasing the angle restriction on the lampshade 4.
[0041] At this time, the lampshade 4 can be rotated to a suitable angle, and the pressing rod 71 can be released. Under the elastic force of the compression spring 73, the limiting plate 72 moves upward, causing the limiting ball 74 to re-enter the limiting groove 75, ensuring that the lampshade 4 can be stably fixed at the required angle to meet the needs of different lighting angles.
[0042] When the desk lamp is not in use, first turn the lever 62 to disengage the connector 61 from the slot 63, then push the connecting rod 55 to move the piston 57 in the opposite direction, allowing air to enter the suction cup 53. The suction cup 53 loses negative pressure and separates from the desktop. Then, fold it using the folding frame 2 to reduce the space occupied by the desk lamp and make it easy to store and carry.
[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
