Description

Technical Field

[0001] This utility model relates to the technical field of desk lamps, and more particularly to a desk lamp with an adjustable angle. Background Technology

[0002] A desk lamp is an electric lamp with a base that is placed on a table. It is small, exquisite, and easy to carry. The main function of a desk lamp is to provide illumination, which is convenient for reading, studying, and working. People cannot do without desk lamps in their daily work and study, especially students.

[0003] Patent CN217382846U discloses a table lamp with an adjustable lighting angle, including a base, a fixed rod fixedly connected to the rear end of the base, a rotating block provided at the end of the fixed rod away from the base, a supporting lamp rod fixedly connected to the surface of the rotating block, a connecting rod provided at the top end of the supporting lamp rod, a movable connecting head provided at the end of the connecting rod away from the supporting lamp rod, and a connecting block fixedly connected to the end of the movable connecting head away from the connecting rod.

[0004] In existing desk lamp adjustment technology, most products rely on friction control for positioning. However, with prolonged use, the friction components are prone to wear, leading to a decrease in clamping force and an inability to stably maintain the lighting angle. Some desk lamps also employ a self-locking structure to enhance the fixing effect, but this type of design usually requires the user to use both hands, which poses significant difficulties in practical use for people with upper limb mobility impairments or those with only one arm, making it difficult for them to complete the adjustment process independently. Utility Model Content

[0005] The purpose of this invention is to provide an angle-adjustable desk lamp in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a base for a table lamp, a movable rod installed at the upper end of the base, a lampshade installed at the upper end of the movable rod, and a locking component and an auxiliary component respectively installed at the hinge positions of the movable rod with the base and the lampshade.

[0007] The locking assembly includes a limiting seat fixed to the outer wall of the movable rod, a limiting cylinder slidably disposed inside the limiting seat, a connecting rod slidably disposed at the middle position of the limiting seat, a metal disc fixedly disposed at one end of the connecting rod inside the limiting cylinder, the other end of the connecting rod passing through the movable rod and the upper fixed rod of the base, a first connecting piece being installed at the other end of the connecting rod, the limiting cylinder being slidably connected to the connecting rod, a magnetic ring being fixedly disposed at the end of the limiting cylinder, the magnetic ring being a neodymium magnet, a metal ring for use with the magnetic ring being pasted inside the limiting seat, a slider being fixedly disposed inside the limiting ring, and a groove for use with the slider being opened on the outer wall of the connecting rod;

[0008] The outer wall of the limiting cylinder is evenly distributed with limiting strips, and the stepped hole in the middle of the limiting seat is provided with a limiting groove for use with the limiting strips;

[0009] In practical applications, the user pushes the limiting cylinder to allow the limiting strip to enter the limiting groove. The magnetic ring inside the limiting cylinder attracts the metal ring, thereby locking the position of the limiting cylinder. The angle is then locked by the engagement of the limiting strip and the limiting groove.

[0010] Furthermore, the auxiliary component includes a second connecting piece located at the middle position of the upper fixed rod of the base, a threaded post threadedly connected to the middle position of the second connecting piece, a screwing block fixedly provided at the end of the threaded post, and a fixed platform for cooperating with the screwing block fixedly provided on the outer wall of the movable rod.

[0011] In practical applications, this device is equipped with an auxiliary component. By rotating the screw block, the screw block is brought closer to the second connecting piece, thereby causing the second connecting piece, the fixed rod, the movable rod, the fixed platform, and the screw block to press against each other, locking the angle between them through compression.

[0012] Furthermore, a limiting platform is fixedly provided at the end of the connecting rod away from the first connecting piece, and a connecting groove for use with the limiting platform is fixedly provided on the outer wall of the first connecting piece. A threaded hole is provided in the middle of the limiting platform, and a screw is threadedly connected to the threaded hole, with the screw penetrating the first connecting piece.

[0013] In practical applications, after the auxiliary components are removed, the through hole at the upper end of the base fixing rod, which is used in conjunction with the threaded post, allows workers to easily use tools to tighten screws.

[0014] Furthermore, the upper fixed rod, movable rod, and connecting rod of the lampshade are all hollow; thus facilitating the passage of wires through the fixed rod, movable rod, and connecting rod.

[0015] Furthermore, an anti-slip pad is affixed to the lower surface of the base where it contacts the desktop.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The user pushes the limiting cylinder, causing the limiting strip to enter the limiting groove. The magnetic ring inside the limiting cylinder attracts the metal ring, thereby locking the position of the limiting cylinder. The angle is then locked by the engagement of the limiting strip and the limiting groove.

[0018] This device is equipped with an auxiliary component that increases the friction between the rotating block and the fixed platform by rotating the screw block, thereby pre-locking the angle and preventing the moving rod from twisting directly with the base or lampshade after the locking component is unlocked.

[0026] Reference Figure 1-4 An angle-adjustable desk lamp includes a base 1, a movable rod 3 is installed on the upper end of the base 1, a lampshade 4 is installed on the upper end of the movable rod 3, and a locking component 2 and an auxiliary component 5 are respectively installed at the hinge positions of the movable rod 3 with the base 1 and the lampshade 4.

[0027] The locking assembly 2 includes a limiting seat 201 fixed to the outer wall of the movable rod 3. A limiting cylinder 202 is slidably arranged inside the limiting seat 201. A connecting rod 203 is slidably arranged at the middle position of the limiting seat 201. A metal disc 204 is fixedly arranged at one end of the connecting rod 203 inside the limiting cylinder 202. The other end of the connecting rod 203 passes through the movable rod 3 and the upper fixed rod of the base 1. A first connecting piece 205 is installed at the other end of the connecting rod 203. The limiting cylinder 202 is slidably connected to the connecting rod 203. A magnetic ring 2022 is fixedly arranged at the end of the limiting cylinder 202. A metal ring 2011 for use with the magnetic ring 2022 is pasted inside the limiting seat 201. A slider is fixedly arranged inside the limiting ring. A groove for use with the slider is opened on the outer wall of the connecting rod 203.

[0028] Limiting strips 2021 are evenly distributed on the outer wall of the limiting cylinder 202, and the stepped hole in the middle of the limiting seat 201 is provided with a limiting groove for use with the limiting strips 2021;

[0029] In practical applications, when the angle needs to be adjusted, the user can first move the limiting cylinder 202 outward to disengage the magnetic ring 2022 from the metal ring 2011. Then, the limiting strip 2021 is disengaged from the limiting groove, and the magnetic ring 2022 approaches and adheres to the metal disc 204. This allows the movable rod 3 and the base 1 or lampshade 4 to rotate freely. The user can then rotate the movable rod 3 or lampshade 4 with one hand to change the angle of the movable rod 3 as needed. After the adjustment is completed, the user pushes the limiting cylinder 202 to allow the limiting strip 2021 to enter the limiting groove. The magnetic ring 2022 inside the limiting cylinder 202 adheres to the metal ring 2011, thereby locking the position of the limiting cylinder 202. The angle is then locked by the engagement of the limiting strip 2021 with the limiting groove.

[0030] Furthermore, refer to Figure 4 The auxiliary component 5 includes a second connecting piece 501 located in the middle of the fixed rod at the upper end of the base 1. A threaded post 502 is threadedly connected to the middle of the second connecting piece 501. A screwing block 503 is fixedly installed at the end of the threaded post 502. A fixed platform 504 for use with the screwing block 503 is fixedly installed on the outer wall of the movable rod 3. Rubber pads can be added at the positions where the second connecting piece 501, the fixed rod, the movable rod 3, the fixed platform 504 and the screwing block 503 fit together.

[0031] In practical applications, this device is equipped with an auxiliary component 5. By rotating the screwing block 503, the screwing block 503 is brought closer to the second connecting piece 501, thereby pressing the second connecting piece 501, the fixed rod, the movable rod 3, the fixed platform 504 and the screwing block 503 against each other, and locking the angle between the connections by pressing.

[0032] Furthermore, refer to Figure 3A limiting platform 2031 is fixedly provided at the end of the connecting rod 203 away from the first connecting piece 205. A connecting groove for use with the limiting platform 2031 is fixedly provided on the outer wall of the first connecting piece 205. A threaded hole is provided in the middle of the limiting platform 2031, and a screw is threaded into the threaded hole. The screw passes through the first connecting piece 205.

[0033] In practical applications, after removing the auxiliary component 5, the through hole at the upper end of the fixing rod of the base 1, which is used in conjunction with the threaded post 502, allows workers to easily use tools to tighten the screws, thereby disengaging the connecting rod 203 from the first connecting piece 205, and making it easier for workers to disassemble and install the locking component 2.

[0034] Furthermore, refer to Figure 1 and Figure 2 The upper fixed rod of the base 1, the movable rod 3, and the connecting rod 203 at one end of the lampshade 4 are all hollow; thus, it is convenient to pass the wire through the fixed rod 203, the movable rod 3, and the connecting rod.

[0035] Furthermore, an anti-slip pad is affixed to the lower surface of the base 1 where it contacts the desktop.

[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
