Description

A table lamp structure Technical Field

[0001] This utility model relates to the field of desk lamp technology, and in particular to a desk lamp structure. Background Technology

[0002] In the field of lighting equipment, table lamps, as commonly used local lighting tools, have always been designed to improve user convenience and experience. Among existing table lamps, the structure of connecting the lamp head and the base via a swingable connecting rod is quite common. This type of table lamp usually has a hinge structure at the connection between the rod and the base / lamp head, and the height of the lamp head is adjusted by rotating the connecting rod around the base, and the positional stability is maintained after adjustment by positioning devices such as dampers.

[0003] However, the aforementioned traditional structure reveals significant drawbacks in practical use: when the user adjusts the lamp head height by swinging the connecting rod, the lamp head's illumination angle changes synchronously due to the rod's swing trajectory, causing the light projection direction to deviate from the expected direction. At this point, the user needs to manually rotate the lamp head to restore it to a horizontal illumination state, making the entire adjustment process cumbersome and time-consuming, requiring two separate steps. Especially in scenarios requiring frequent adjustments to lighting height and angle, such as in office or study environments, this split-type adjustment method severely impacts efficiency and fails to meet users' needs for convenience and rapid, accurate positioning. Summary of the Invention

[0004] The purpose of this utility model is to provide a table lamp structure that addresses the defects and shortcomings of the existing technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0012] The first bottom connecting hole is hinged to the first lower connecting hole; the second lower connecting hole is hinged to the second bottom connecting hole.

[0013] Furthermore, the hinge shaft connecting the second lower connecting hole and the second bottom connecting hole is a damping shaft; the two ends of the damping shaft are respectively fixed on the second lower connecting hole and the second bottom connecting hole.

[0014] Furthermore, the first rod has a first hanging hole at the end near the upper connecting block; the second rod has a second hanging hole at the end near the lower connecting block; a spring is connected between the second hanging hole and the first hanging hole; the spring is disposed in the gap between the first rod and the second rod.

[0017] Furthermore, a rotating seat is rotatably connected to the top of the upper support rod; the rotating seat is fixed to the lamp head.

[0018] Furthermore, the lamp head can be any one of the following shapes: ring shape, circle shape, elliptical shape, elliptical ring shape, and strip shape.

[0019] Furthermore, the lamp head is a ring-shaped lamp head; one end of the rotating seat is rotatably connected to the upper support rod; the other end of the rotating seat is fixed with a fixing rod; the end of the fixing rod is fixed to the inner side wall of the ring-shaped lamp head; the rotation center of the rotating seat is offset from the axis of the lamp head.

[0020] Furthermore, a sensor is provided on the lamp head.

[0021] With the above structure, the beneficial effects of this utility model are as follows: Since the opposite sides of the parallelogram frame are always parallel, and the two sides connecting the lamp head and the base are parallel to each other, and one side is fixed to the base, the side connected to the base will not rotate during the folding process of the parallelogram frame, so the angle of the side connected to the lamp head will not change; the other two rods can rotate around the side connected to the swing base when the parallelogram is folded; therefore, the lamp head can be translated in the height direction by folding the parallelogram frame, and the height adjustment of the lamp head can be achieved in one step, which is simple to operate and more convenient to use.

[0038] The present invention will be further described below with reference to the accompanying drawings.

[0039] As shown in Figures 1 to 8, the table lamp structure of this utility model includes a base 1, a folding rod 2, and a lamp head 5 connected to the folding rod 2.

[0040] The folding rod 2 is a parallelogram frame; adjacent sides of the parallelogram frame are hinged to each other; one pair of opposite sides of the parallelogram frame are fixed to the base 1 and the lamp head 5 respectively;

[0041] Since opposite sides of the parallelogram frame are always parallel, and the two sides connecting the lamp head 5 and the base 1 are parallel to each other, and one of them is fixed to the base 1, the side connected to the base 1 will not rotate during the folding of the parallelogram frame. Therefore, the angle of the side connected to the lamp head 5 will not change. The other two rods can rotate around the side connected to the swing base 1 when the parallelogram is folded. Therefore, the lamp head 5 can be translated in the height direction by folding the parallelogram frame. The height adjustment of the lamp head 5 can be achieved in one step, which is simple to operate and more convenient to use.

[0042] As a preferred embodiment of this utility model, the parallelogram frame includes a first rod 202, a second rod 204, an upper connecting block 201 connected to the lamp head 5, and a lower connecting block 205 connected to the base 1.

[0043] The upper connecting block 201 is provided with a first upper connecting hole 20101 and a second upper connecting hole 20102; the lower connecting block 205 is provided with a first lower connecting hole 20501 and a second lower connecting hole 20502; the distance between the first upper connecting hole 20101 and the second upper connecting hole 20102 is a first distance; the distance between the first lower connecting hole 20501 and the second lower connecting hole 20502 is a second distance; the first distance is equal to the second distance;

[0044] The first rod 202 is provided with a first top connecting hole 20202 and a first bottom connecting hole 20203; the second rod 204 is provided with a second bottom connecting hole 20402 and a second top connecting hole 20403; the distance between the first top connecting hole 20202 and the first bottom connecting hole 20203 is a third distance; the distance between the second bottom connecting hole 20402 and the second top connecting hole 20403 is a fourth distance; the third distance is equal to the fourth distance.

[0045] The first top connecting hole 20202 is hinged to the first upper connecting hole 20101; the second top connecting hole 20403 is hinged to the second upper connecting hole 20102;

[0046] The first bottom connecting hole 20203 is hinged to the first lower connecting hole 20501; the second lower connecting hole 20502 is hinged to the second bottom connecting hole 20402;

[0047] A parallelogram structure is formed by hinged connection of the upper connecting block 201, the first rod 202, the second rod 204 and the lower connecting block 205.

[0048] In a preferred embodiment of this utility model, the hinge connecting the second lower connecting hole 20502 and the second bottom connecting hole 20402 is a damping rotating shaft 20503; the two ends of the damping rotating shaft 20503 are respectively fixed on the second lower connecting hole 20502 and the second bottom connecting hole 20402.

[0049] The damping pivot 20503 is not fundamentally different from existing technology, so it will not be described in detail. The damping pivot 20503 can generate resistance to prevent the first rod 202 from rotating relative to the lower connecting block 205, so that the parallelogram frame can remain stable without external force. When it is necessary to fold the parallelogram frame, force needs to be applied to overcome the resistance of the damping pivot 20503.

[0050] In a preferred embodiment of this utility model, the first rod 202 is provided with a first hanging hole 20201 at one end near the upper connecting block 201; the second rod 204 is provided with a second hanging hole 20401 at one end near the lower connecting block 205; a spring 203 is connected between the second hanging hole 20401 and the first hanging hole 20201; the spring 203 is disposed in the gap between the first rod 202 and the second rod 204;

[0051] Spring 203 is always in a stretched state; spring 203 generates an upward torque on the first rod 202 about the first lower connecting hole 20501; while spring 203 generates a downward torque on the second rod 204 about the second lower connecting hole 20502; since the elastic forces of spring 203 are equal, but the equivalent force arm of the first rod 202 is much larger than that of the second rod 204;

[0052] Therefore, when the parallelogram frame is flipped down, the torque generated by the spring 203 counteracts most of the torque generated by the lamp head 5 and the parallelogram frame; similarly, when the parallelogram frame is flipped up, the torque generated by the spring 203 counteracts most of the torque generated by the lamp head 5 and the parallelogram frame; making the feel of the quadrilateral frame consistent when flipping up or down.

[0053] In a preferred embodiment of this utility model, the lower connecting block 205 is rotatably connected to the base 1; the circuit inside the base 1 and the circuit inside the lower connecting block 205 are connected through a rotatable connector; the lower connecting block 205 and the entire parallelogram frame can rotate on the base 1, which can adjust the different illumination ranges of the lamp head.

[0054] In a preferred embodiment of this utility model, an upper support rod 3 is rotatably connected to the upper connecting block 201; the lamp head 5 is connected to the top of the upper support rod 3; the angle between the upper support rod 3 and the horizontal plane is 0-90°; an outer sleeve 206 is fixed between the upper connecting block 201 and the lower connecting block 205; the first rod 202 and the second rod 204 are both disposed inside the outer sleeve 206.

[0055] The outer sleeve 206 and the upper support rod 3 are combined to form a cantilever structure, which causes the light emission positions of the base 1 and the lamp head 5 to be misaligned.

[0056] In a preferred embodiment of this utility model, the top of the upper support rod 3 is rotatably connected to a rotating seat 4; the rotating seat 4 is fixed on the lamp head 5; the rotating seat 4 is not fundamentally different from the prior art, so it will not be described in detail here; the circuit connection between the rotating seat 4 and the inside of the upper support rod 3 is connected through a rotatable connector to adjust the light output position of the lamp head 5.

[0057] In a preferred embodiment of this utility model, the lamp head 5 is any one of the following shapes: ring shape, circle shape, elliptical shape, elliptical ring shape, and strip shape.

[0058] In a preferred embodiment of this utility model, the lamp head 5 is a ring-shaped lamp head; one end of the rotating seat 4 is rotatably connected to the upper support rod 3; the other end of the rotating seat 4 is fixed with a fixing rod 6; the end of the fixing rod 6 is fixed to the inner side wall of the ring-shaped lamp head; the rotation center of the rotating seat 4 is offset from the axis of the lamp head 5.

[0059] When the eccentrically positioned ring-shaped lamp head rotates around the support rod 3, the center of the lamp head 5 also makes a circular motion, which can finely adjust the light emission position of the lamp head 5.

[0060] As a preferred embodiment of this utility model, a sensor 7 is provided on the lamp head 5; in actual application, the sensor 7 is installed on the fixed rod 6. The sensor 7 is not fundamentally different from the prior art. After the sensor senses the signal and feeds it back to the controller, it can produce different light output effects.

[0061] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
