Description

Technical Field

[0001] This utility model relates to the field of desk lamp technology, specifically to a folding structure for a desk lamp. Background Technology

[0002] Folding table lamps, with their flexible design and convenient storage, are an ideal choice for those with limited space or who need to frequently adjust the lighting position. These lamps typically feature one or more bendable, foldable, or rotatable parts, allowing users to freely adjust the direction and angle of the light according to their needs. However, in pursuing flexibility and portability, current folding table lamps face issues such as a shift in the center of gravity and a reduced bottom contact area when unfolded, leading to decreased overall stability and making them easily tipped over. While clamps are used to address this, adding clamps to the bottom of the lamp to directly fix it to the table improves stability; however, the clamps themselves are not foldable, further reducing the overall portability of the lamp.

[0003] Therefore, it is necessary to propose a folding structure for a desk lamp that can effectively improve the stability of the folding desk lamp while also ensuring portability. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the present invention provides a folding structure for a table lamp.

[0005] The technical solution of this utility model is: a folding structure for a table lamp, including a mounting base, a first connecting base, a first folding frame, a second folding frame, a second connecting base, a lighting lamp, a guide frame, a fastening rod, and a torsion spring. The mounting base is slidably mounted on the guide frame, and the first connecting base is rotatably mounted on the mounting base. The first folding frame is hinged to the first connecting base, and the second folding frame is hinged to the end of the first folding frame. The second connecting base is hinged to the end of the second folding frame, and the lighting lamp is rotatably mounted on the second connecting base. Fastening rods with front-to-back spacing are rotatably mounted at both ends of the guide frame, and a torsion spring is provided between the fastening rod and the inner wall of the guide frame.

[0006] Furthermore, the locking rod is L-shaped.

[0007] Furthermore, it also includes a heat dissipation frame and a heat sink. Both sides of the lighting lamp are provided with a heat dissipation frame with arranged heat dissipation holes, and a heat sink is installed inside the heat dissipation frame.

[0008] Furthermore, it also includes filters; filters are installed on the vents at the rear end of the heat dissipation frame.

[0009] Furthermore, it also includes locking rods, with locking rods inserted at both ends of the mounting base to engage with the guide frame.

[0010] Furthermore, it also includes friction pads, with friction pads installed around the bottom of the guide frame.

[0011] This utility model has the following advantages: Through its innovative snap-fit ​​rod design, the table lamp can adapt to different placement environments (such as flat surfaces or edges) and flexibly adjust the support method. This not only increases the contact area between the table lamp and the support surface but also provides a clamping and fixing function, ensuring that the table lamp is more stable during use and less likely to be knocked over. In addition, by pushing the mounting base along the guide frame, the center of gravity of the device can be adjusted to achieve the best balance, further improving the safety of use. It can be seen that the overall structure maintains good foldability. In particular, the design of the snap-fit ​​rod and torsion spring not only saves space but also automatically resets, making the table lamp easy to carry and store while ensuring stability.

Detailed Implementation

[0017] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0018] Example: A folding structure for a table lamp, such as Figures 1-3As shown, the device includes a mounting base 1, a first connecting base 2, a first folding frame 3, a second folding frame 4, a second connecting base 5, a lighting lamp 6, a guide frame 7, a fastening rod 8, and a torsion spring 9. The mounting base 1 is slidably mounted on the guide frame 7, allowing it to slide left and right along the guide frame 7. The first connecting base 2 is rotatably mounted on the mounting base 1. The first folding frame 3 is hinged to the first connecting base 2. The second folding frame 4 is hinged to the end of the first folding frame 3, and the second connecting base 5 is hinged to the end of the second folding frame 4. The lighting lamp 6 is rotatably mounted on the second connecting base 5. Dampers are installed at each hinge point for stable adjustment. Through the coordinated operation of all components, the lighting lamp 6 at the top can slide and hinge. The lamp features various movement methods, including connecting and rotating. The sliding function assists in adjusting the center of gravity of the entire device, enhancing stability. Combined with the hinged and rotating design of the multi-layered first connecting seat 2, first folding frame 3, second folding frame 4, and second connecting seat 5, the lamp not only supports multi-layered folding operations but also allows for flexible angle adjustment. This ensures both high portability and comprehensive and flexible use of the device. Through optimization, the lamp meets both the needs of convenient portability and practical application, providing users with a more comfortable and efficient user experience. Both ends of the guide frame 7 are equipped with interlocking rods 8 that are spaced back and forth. The interlocking rods 8 are L-shaped and a torsion spring 9 is installed between the interlocking rods 8 and the inner wall of the guide frame 7.

[0019] Specifically, to further improve the overall portability and stability of the desk lamp, a snap-fit ​​design with snap-fit ​​rods arranged around the perimeter is adopted. The snap-fit ​​rods 8 are L-shaped, allowing for adjustments to the usage method according to different placement environments.

[0020] First, when placed on a flat surface, the entire structure can be placed directly on the surface. Under the action of the torsion spring 9, the locking rod 8 is in a flat state, which increases the support area at the bottom of the guide frame 7, thereby improving the overall stability and support effect. Second, when it is necessary to place the equipment on the edge of the table, it can be fixed by rotating the locking rod 8 on the side closest to the edge of the table. The torsion spring 9 deforms accordingly, allowing the corresponding locking rod 8 to fold and embed under the table, so that the lower part of the locking rod 8 is at the bottom of the table. Then, the locking rod 8 is released, and under the restoring force of the torsion spring 9, the locking rod 8 will rotate upward to fit and clamp the bottom of the table. Combined with its special L-shaped structure, it clamps the bottom of the table to achieve a stable clamping effect. At this time, the other two locking rods 8 are still in a flat state and provide necessary support for the rear end of the structure, which significantly enhances the overall stability. This not only overcomes the problem that traditional clamps cannot be folded, but also allows the equipment to flexibly adapt to various placement environments, greatly improving the convenience and flexibility of use.

[0021] like Figure 4As shown, it also includes a heat dissipation frame 10 and a heat sink 11. Both sides of the lighting lamp 6 are provided with heat dissipation frames 10 with arranged heat dissipation holes. Heat sinks 11 are provided in the heat dissipation frames 10. This can effectively improve the heat dissipation efficiency when the lighting lamp 6 is working, ensure that the lamp can maintain a good working condition, and avoid performance degradation or damage due to overheating.

[0022] like Figure 4 As shown, it also includes a filter screen 12. The vents at the tail end of the heat dissipation frame 10 are all equipped with filter screens 12, which can effectively block dust and other small particles from entering the equipment, reduce damage to the internal components of the lighting lamp 6, ensure air circulation, further assist the heat dissipation effect, and extend the service life of the equipment.

[0023] like Figure 3 As shown, it also includes a locking rod 13. The locking rod 13 is inserted at both the front and rear ends of the mounting base 1 to engage with the guide frame 7, so as to fix the position between the mounting base 1 and the guide frame 7.

[0024] like Figure 3 As shown, it also includes friction pads 14. Friction pads 14 are provided around the bottom of the guide frame 7. The friction pads 14 can enhance the friction between the equipment and the placement surface, improve the stability of the equipment when it is placed, prevent slippage, and also reduce damage to the surface of the table or other placement platform.

[0025] Depending on the usage requirements, the position of the lighting lamp 6 and its overall folding structure can be adjusted by sliding the mounting base 1 along the guide frame 7, thereby changing the overall center of gravity. First, the folding state of the lighting lamp 6 can be adjusted by manipulating the first and second folding frames 4, and the lighting lamp 6 can be rotated along the second connecting seat 5 to achieve the desired unfolding effect. After the initial adjustment, the mounting base 1 can be further slid to precisely calibrate the overall center of gravity position. When selecting the placement state, if the placement platform is flat, the surrounding fastening rods 8 can be unfolded to increase the contact area between the guide frame 7 and the supporting surface, ensuring the stability of the device. When the device needs to be placed at the edge of the support platform, the two latching rods 8 near the platform edge can be rotated to fold them in place. The torsion spring 9 then deforms, placing the guide frame 7 on the support platform and embedding the latching rods 8 into the side of the platform. Releasing the latching rods 8 releases the torsion spring 9, causing the connected latching rods 8 to rotate and return to their extended state. The latching rods 8 then adhere to the bottom surface of the platform and are clamped and fixed by the torsion spring 9. Simultaneously, the two latching rods 8 on the other side remain extended on the platform, providing stable support for the rear of the device. This not only improves the flexibility of use but also ensures the safety and stability of the device.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
