Description

Technical Field

[0001] This utility model belongs to the field of lighting fixtures, specifically relating to a table lamp that can be raised, lowered, retracted, and adjusted at multiple angles. Background Technology

[0002] As a portable lighting fixture, a table lamp is mainly placed on a desktop for illumination.

[0003] Currently, in order to adapt to users' lighting needs at different angles or heights, existing desk lamps usually adopt an adjustable lamp head design. For example, Chinese patent publication number CN219199077U discloses an adjustable angle desk lamp, including a base, a support assembly, a connecting rod, a lighting lamp, and a fixing mechanism; the support assembly is disposed on the base; the connecting rod is rotatably disposed on the support assembly; the lighting lamp is rotatably disposed on the first end of the connecting rod; the fixing mechanism is configured to detachably fix the lighting lamp to the first end of the connecting rod.

[0004] However, in practical use, the existing technology has the following drawbacks:

[0005] 1. In order to meet the rotation space requirements of the linkage, the overall size of the desk lamp is relatively large, which greatly affects the utilization of desktop space;

[0006] 2. When adjusting the angle of the lamp by rotating the linkage, the lateral illumination distance of the lamp is limited. Therefore, when it is necessary to illuminate a distant location, the entire position of the lamp needs to be moved, which is very cumbersome and inconvenient. Summary of the Invention

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved table lamp that can be raised, lowered, retracted, and adjusted at multiple angles.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A height-adjustable, retractable, and multi-angle adjustable desk lamp includes a support, a retractable assembly, and a lamp head module. The retractable assembly includes a first rod group connected to the support and having a telescopic end, and a second rod group having a connecting end and a sliding end. The second rod group is connected to the first rod group from the connecting end and is slidably connected to the support from the sliding end. The lamp head module is movably connected to the telescopic end and can be flipped and adjusted in the vertical and / or horizontal directions. As the sliding end slides up and down, the connecting end drives the first and second rod groups to fold or unfold relative to the support, and the telescopic end drives the lamp head module to move synchronously downward and closer to the support or upward and away from the support.

[0010] According to a specific embodiment and preferred aspect of this utility model, the first linkage group includes a first connecting rod fixed to the upper part of the bracket, a second connecting rod rotatably connected to the second linkage group and forming a telescopic end at one end, and a third and fourth connecting rod rotatably connected from both ends between the first and second connecting rods. As the sliding end slides up and down, the connecting end drives the second connecting rod and causes the third and fourth connecting rods to rotate around the rotation center line on the first connecting rod. Here, the first, second, third, and fourth connecting rods form a four-link linkage group, which has a stable structure, which is beneficial to increasing the weight of the lamp head module that can be connected, and it is flexible in flipping, with less wear and a long service life. In addition, during the extension and retraction, the height of the second connecting rod changes accordingly, thereby driving the lamp head module to extend, retract, and adjust in height synchronously through the telescopic end.

[0011] Preferably, the first link and the second link are arranged in parallel; the third link and the fourth link are arranged in parallel.

[0012] Preferably, the second link group is rotatably connected to the third link from the connecting end to the end of the second link away from the telescopic end; the fourth link is rotatably connected to the second link from the corresponding end and is located between the connecting end and the telescopic end.

[0013] Preferably, the first link extends horizontally, and when extended, the first, second, third, and fourth links are parallel to each other. This maximizes the extension distance, thereby increasing the adjustment range of the lamp head module.

[0014] Preferably, the second linkage includes a sliding sleeve fitted onto the bracket and forming a sliding end, and a fifth connecting rod rotatably connected to the sliding sleeve from one end, wherein the other end of the fifth connecting rod forms a connecting end. This design is simple and easy to install and implement.

[0015] Preferably, an elastic element capable of keeping the sliding sleeve suspended at any height is connected between the sliding sleeve and the upper part of the bracket. In some specific embodiments, the elastic element is a constant-force spring to achieve adjustment at any height within the stroke range, meeting different lighting needs.

[0016] Preferably, the lamp head module includes a flip module rotatably connected to the telescopic end about a horizontal centerline, a connecting module rotatably connected to the flip module about a vertical centerline, and a lamp head fixed to the connecting module.

[0017] In some specific embodiments, the flipping module and the telescopic end are rotatably connected via a pivot, wherein the pivot is provided with a spring that generates rotational torque. Here, the generated torque is constant, maintaining a stable flipping feel.

[0018] In other embodiments, a rotating shaft capable of moving and adjusting along the rotation center line is provided between the flipping module and the telescopic end. A spring plate located at one end of the rotating shaft and generating rotational torque is also provided. As the rotating shaft moves along the rotation center line and contacts the spring plate, the rotational torque generated by the spring plate increases or decreases accordingly. This allows the user to adjust the torque according to their needs.

[0019] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art:

[0020] Existing technologies, in order to meet the rotation space requirements of the linkage, result in a large overall size of the desk lamp, which significantly affects the utilization of desktop space. Furthermore, when adjusting the lighting angle by rotating the linkage, the lateral illumination distance is limited. Therefore, to illuminate a distant location, the entire desk lamp needs to be moved, which is cumbersome and inconvenient. This application, however, provides a comprehensive structural design for a height-adjustable, retractable, and multi-angle adjustable desk lamp, cleverly addressing the shortcomings and defects of existing technologies. With this desk lamp, for long-distance illumination, the sliding end of the second linkage group is adjusted, causing the connecting end of the second linkage group to extend relative to the support frame. This, in turn, causes the lamp head module to extend away from the support frame and move upwards via the telescopic end of the first linkage group. For short-distance illumination or when the lamp is folded down, the sliding end of the second linkage group is adjusted in the opposite direction, causing the connecting end of the second linkage group to fold relative to the support frame. This, in turn, causes the lamp head module to retract closer to the support frame and move downwards via the telescopic end of the first linkage group. In addition, the lighting angle of the lamp head module can be adjusted by rotating it horizontally or vertically according to the required lighting angle. Therefore, compared with the prior art, this utility model, on the one hand, is based on the cooperation of the first and second rod groups, and the relative support can be folded or unfolded by operating the second rod group to meet the usage needs of the table lamp in different spaces and improve the space utilization rate; on the other hand, the lamp head module can be extended and retracted synchronously with the folding and unfolding components, thereby meeting the lighting needs of different distances. In addition, based on the flip adjustment of the vertical and horizontal center lines, the table lamp can flexibly realize multi-angle lighting, which is simple and convenient to use.

[0036] Example 1

[0037] like Figures 1 to 4 As shown, the height-adjustable and multi-angle adjustable desk lamp of this embodiment includes a bracket 1, a retractable assembly 2, and a lamp head module 3.

[0038] Specifically, the support 1 includes a base 10 at the bottom and a support rod 11 vertically connected to the base 10.

[0039] In this example, the retractable assembly 2 includes a first rod group 21 connected to the support pole 11 and having a telescopic end d1, and a second rod group 22 having a connecting end d2 and a sliding end d3. The second rod group 22 is connected to the first rod group 21 from the connecting end d2 and is slidably connected to the support pole 11 from the sliding end d3. The lamp head module 3 is movably connected to the telescopic end d1 and can be flipped and adjusted in the vertical and / or horizontal directions. As the sliding end d3 slides up and down, the connecting end d2 drives the first rod group 21 and the second rod group 22 to fold or unfold relative to the support 1, and the telescopic end d1 drives the lamp head module 3 to move downward and closer to the support 1 or upward and away from the support 1 synchronously.

[0040] In some specific embodiments, the first rod group 21 includes a first connecting rod 211 fixed to the upper part of the frame rod 11, a second connecting rod 212 rotatably connected to the second rod group 22 and forming a telescopic end d1 from one end, and a third connecting rod 213 and a fourth connecting rod 214 rotatably connected from both ends between the first connecting rod 211 and the second connecting rod 212. As the sliding end d3 slides up and down, the connecting end d2 drives the second connecting rod 212 and causes the third connecting rod 213 and the fourth connecting rod 214 to rotate around the rotation center line on the first connecting rod 211, and the telescopic end d1 synchronously extends and retracts and moves up and down. In other words, according to the arc-shaped motion trajectory of the end formed by the rotation of the third connecting rod 213 and the fourth connecting rod 214, the second connecting rod 212 moves downward toward the support 1 or upward away from the support 1, and the lamp head module 3 synchronously performs extension, retraction, and lifting adjustments. Here, the first, second, third, and fourth links form a four-bar linkage, which is structurally stable, helps to increase the weight of the lamp head module that can be connected, and is flexible to flip, with little wear and long service life; in addition, the second link changes height accordingly during the extension and retraction, thereby driving the lamp head module to extend, retract, and adjust in height synchronously through the telescopic end.

[0041] For ease of implementation, the first link 211 and the second link 212 are arranged in parallel; the third link 213 and the fourth link 214 are arranged in parallel.

[0042] Simultaneously, the second link assembly 22 is rotatably connected to the third link 213 coaxially from the connecting end d2 to the end of the second link 212 away from the telescopic end d1; the fourth link 214 is rotatably connected to the second link 212 from its corresponding end and is located between the connecting end d2 and the telescopic end d1. To avoid interference, the third link 213 and the fourth link 214 are misaligned in the thickness direction of the second link 212.

[0043] In some specific embodiments, the first link 211 extends horizontally, and when extended, the first link 211, the second link 212, the third link 213, and the fourth link 214 are parallel to each other. This maximizes the extension distance, thereby increasing the adjustment range of the lamp head module.

[0044] In this example, the second linkage 22 includes a sliding sleeve 220 sleeved on the bracket and forming a sliding end d3, and a fifth connecting rod 221 rotatably connected to the sliding sleeve 220 from one end, wherein the other end of the fifth connecting rod 221 forms a connecting end d2. This design is simple and easy to install and implement.

[0045] To further facilitate implementation, an elastic element t is connected between the sliding sleeve 220 and the upper part of the support rod 11, which can keep the sliding sleeve 220 suspended at any height. In some specific embodiments, the elastic element t is a constant-force spring to achieve adjustment at any height within the stroke range to meet different lighting needs.

[0046] In this example, the lamp head module 3 includes a flip module 30 that is rotatably connected to the telescopic end d1 about the horizontal center line, a connecting module 31 that is rotatably connected to the flip module 30 about the vertical center line, and a lamp head fixed to the connecting module 31 (not shown in the figure, but easy to imagine).

[0047] In some specific embodiments, the flipping module 30 and the telescopic end d1 are rotatably connected via a rotating shaft s, wherein the rotating shaft s is provided with a spring piece p that generates rotational torque. An external bolt is fitted onto the rotating shaft s and abuts against the spring piece P to generate a constant torque. Here, the generated torque is constant, maintaining a stable flipping feel.

[0048] In summary, when using this desk lamp, for long-distance lighting, the sliding end of the second rod group is adjusted by sliding it. The connecting end of the second rod group then causes the first and second rod groups to extend relative to the support, and the telescopic end of the first rod group then moves the lamp head module away from the support and upwards. For short-distance lighting or when the lamp is folded down, the sliding end of the second rod group is adjusted in the opposite direction. The connecting end of the second rod group then causes the first and second rod groups to fold relative to the support, and the telescopic end of the first rod group then moves the lamp head module closer to the support to retract and downwards. Furthermore, depending on the required lighting angle, the lighting angle of the lamp head module can be adjusted by rotating it around the vertical and horizontal center lines respectively. Therefore, compared with the prior art, this utility model, on the one hand, is based on the cooperation of the first and second rod groups, and the relative support can be folded or unfolded by operating the second rod group to meet the usage needs of the table lamp in different spaces and improve the space utilization rate; on the other hand, the lamp head module can be extended and retracted synchronously with the folding and unfolding components, thereby meeting the lighting needs of different distances. In addition, based on the flip adjustment of the vertical and horizontal center lines, the table lamp can flexibly realize multi-angle lighting, which is simple and convenient to use.

[0049] Example 2

[0050] like Figure 5 and Figure 6As shown, the height-adjustable, retractable, and multi-angle adjustable desk lamp of this embodiment has a basically the same structure as that of Embodiment 1, the difference being:

[0051] In this embodiment, a rotating shaft s capable of moving and adjusting along the rotation center line is provided between the flipping module 30 and the telescopic end d1. A spring piece p, located at one end of the rotating shaft s and generating rotational torque, is also provided. As the rotating shaft s moves along the rotation center line and contacts the spring piece p, the rotational torque generated by the spring piece p increases or decreases accordingly. For ease of adjustment, the rotating shaft s uses a bolt adjustment component. The rotational torque generated by the spring piece p is adjusted by rotating the exposed operating end of the rotating shaft s. This allows the user to adjust the torque according to their needs.

[0052] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
