[0001] This utility model belongs to the field of desk lamp adjustment technology, specifically a desk lamp with multi-angle head adjustment. Background Technology

[0002] A desk lamp is a common household appliance, mainly used to provide local lighting. It is commonly found in homes, offices, and studies. The adjustment range of a desk lamp is limited, and its deformable structure is prone to sagging when bent.

[0003] Meanwhile, a foldable desk lamp with multi-angle adjustment, application number CN202120604643.2, "includes a lamp head assembly, a lamp pole assembly, and a mounting base assembly. The lamp pole assembly includes a first hollow tube and a second hollow tube hinged at one end. The other end of the first hollow tube is hinged to the top of the mounting base assembly. The other end of the second hollow tube is hinged to a connecting component. The connecting component is rotatably connected to the lamp head assembly. A magnifying glass is provided on the lamp head assembly."

[0004] The existing desk lamp angle adjustment structure uses a bent connecting rod as the main structure for adjusting the lamp angle. Because the structure is relatively flexible, it is convenient to adjust the lamp's illumination angle. However, the flexible structure is relatively long, which can easily lead to a heavy lamp head, causing the lamp head to sag and resulting in poor positioning stability, thus affecting the adjusted lamp's illumination angle.

[0005] Therefore, a multi-angle adjustable desk lamp for the head is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a multi-angle adjustable table lamp with the advantages of shortening the length of the flexible adjustment structure and adding a stabilizing adjustment component to maintain the lamp body's illumination angle and reduce sagging.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle adjustable desk lamp for the head, including a lamp post, an adjusting rod rotatably disposed inside the top end of the lamp post, and an adjusting and stabilizing component at the other end of the adjusting rod;

[0008] The adjusting and stabilizing assembly includes a bent plate fixedly mounted on the other end of the adjusting rod, an intermediate cover fixedly mounted below the other end of the bent plate, a gasket fixedly mounted at the bottom end of the intermediate cover, an adjusting housing fitted to the bottom surface of the gasket, a universal joint rotatably mounted inside the adjusting housing, a telescopic shaft fixedly mounted on the outer side of the universal joint, and the other end of the telescopic shaft fixedly mounted to the intermediate cover, a lamp body fixedly mounted at the bottom end of the adjusting housing, a positioning hole opened at the top end of the adjusting housing, and the positioning hole is beveled at the opening on the surface of the adjusting housing, the bent plate is a rigid memory board, and a lampshade head is fixedly mounted above the other end of the bent plate.

[0009] Preferably, a spring is sleeved on the outer side of the telescopic shaft, and the spring is located between the washer and the universal joint.

[0010] Preferably, the adjusting rod is configured with a two-end docking structure, and a rotating head is rotatably provided at both ends of the adjusting rod.

[0011] Preferably, a base is fixedly provided at the bottom end of the lamp post, a threaded shaft is fixedly provided at the bottom end of the base, a circular plate is fixedly provided at the other end of the threaded shaft, and a clamping plate is spirally provided on the outer side of the threaded shaft.

[0012] Preferably, a guide rod is fixedly provided at the bottom end of the clamping plate, the guide rod is helically arranged with the threaded shaft, and a base that slidably fits against the circular plate is provided on the outer side of the guide rod.

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

[0014] 1. This utility model, by adjusting the bending plate in the stabilizing component and adjusting the outer shell structure, allows the adjusting outer shell with the inclined surface to be positioned after adjustment, maintaining the stable illumination of the lamp body structure. The shorter bending plate can effectively prevent the lamp body structure from sagging. After adjustment, the lamp can maintain illumination at different angles for a long time.

[0015] 2. This utility model uses a base, clamping plate, and threaded shaft. By rotating the base at different heights on the outside of the threaded shaft, it is easier to control the clamping plate to rise and clamp it at the edge of the table for positioning. After clamping, the base is released and slides down to the top of the circular plate for counterweight, thus maintaining the stability of the lamp post. Attached Figure Description

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.

[0024] like Figures 1 to 4 As shown, this utility model provides a multi-angle adjustable desk lamp, including a lamp post 1, an adjusting rod 2 rotatably disposed inside the top end of the lamp post 1, and an adjusting and stabilizing component 4 at the other end of the adjusting rod 2;

[0025] The adjusting and stabilizing assembly 4 includes a bent plate 42 fixedly mounted on the other end of the adjusting rod 2. An intermediate cover 43 is fixedly mounted below the other end of the bent plate 42. A shim 46 is fixedly mounted at the bottom of the intermediate cover 43. Adding the shim 46 increases friction and reduces slippage. An adjusting housing 44 is fitted to the bottom surface of the shim 46. A universal joint 49 is rotatably mounted inside the adjusting housing 44. A telescopic shaft 47 is fixedly mounted on the outer side of the universal joint 49, and the other end of the telescopic shaft 47 is fixedly mounted to the intermediate cover 43. The bottom of the adjusting housing 44... A lamp body 5 is fixedly installed and connected to a universal head 49 via a telescopic shaft 47 for rotation and adjustment to different positions, making it convenient to use. The top of the adjustment housing 44 has a positioning hole 45, and the positioning hole 45 is located at the opening on the surface of the adjustment housing 44 and is set in a bevel shape. The bevel shape of the outlet end of the adjustment housing 44 can maintain the positioning stability after adjustment. The bending plate 42 is set as a rigid memory plate, and a lampshade head 41 is fixedly installed on the other end of the bending plate 42. The structure of the bending plate 42 can provide more multi-directional adjustment positions, and the structure of the lampshade head 41 increases protection.

[0026] Specifically, a spring 48 is sleeved on the outer side of the telescopic shaft 47. The spring 48 is located between the gasket 46 and the universal head 49. The spring 48 structure pulls and stretches the telescopic shaft 47, which can pull the gasket 46 to tighten on the surface of the adjusting housing 44.

[0027] It is worth noting that the adjusting rod 2 is designed with a two-end docking structure, and a rotating head 3 is rotatably installed at the two ends of the adjusting rod 2. The adjusting rod 2 can be adjusted to different directions by rotating the rotating head 3.

[0028] It is worth noting that a base 6 is fixedly installed at the bottom of the lamp post 1, a threaded shaft 7 is fixedly installed at the bottom of the base 6, a circular plate 10 is fixedly installed at the other end of the threaded shaft 7, and a clamping plate 11 is spirally installed on the outer side of the threaded shaft 7. By rotating the clamping plate 11, it can move to the outside of the threaded shaft 7 and clamp and position it below the base 6, thereby clamping the positioning structure located between them and completing the positioning.

[0029] It is worth mentioning that a guide rod 9 is fixedly installed at the bottom of the clamping plate 11. The guide rod 9 guides the base 8 and controls the base 8 to move up and down to maintain stability. The guide rod 9 is spirally connected to the threaded shaft 7. The base 8, which is in contact with the circular plate 10, is slidably installed on the outside of the guide rod 9. The added base 8 structure can provide more handholds and make rotation more convenient.

[0030] The above are existing technologies and will not be described in detail. In addition, this utility model also includes power supplies, controllers and switches, which are not the main technical points of this patent and will not be described in detail.

[0031] Working principle and process:

[0032] Before using the desk lamp for lighting, the user places the lamp post 1 on the edge of the desktop via the base 6. Rotating the base 8 on the outside of the threaded shaft 7 connects to the clamping plate 11 via the guide rod 9. Rotating the base 8 raises it on the outside of the threaded shaft 7, controlling the guide rod 9 and the clamping plate 11 above the guide rod 9 to move closer to the base 6, positioning the lamp post 1 on the edge of the desktop. Alternatively, the round plate 10 can be placed directly on the desktop, with the base 8 on the outside of the guide rod 9 sliding into contact with the round plate 10, increasing the counterweight of the round plate 10 and stabilizing the lamp post 1, allowing it to be placed directly on the desktop for use.

[0033] Using lamp post 1, rotate the adjustment rod 2 at the connection point with lamp post 1. Simultaneously, rotate the adjustment rod 2 laterally, and adjust it to different positions via the rotating head 3. The bending plate 42 can be adjusted to change different illumination directions of lamp body 5. When a larger position adjustment is needed, lamp body 5 can be pulled down. By pulling down the adjusting housing 44, the telescopic shaft 47 is stretched, and the outer spring 48 is stretched, separating the shim 46 from the adjusting housing 44. The shim 46 can be rotated to the corresponding outlet position. Release lamp body 5, and the spring 48 will tighten it, pulling the adjusting housing 44 to press against the surface of the shim 46 for positioning. After adjustment, the positioning is more stable.
