Description

Technical Field

[0001] The utility model relates to the technical field of desk lamps, and more particularly to a telescopic desk lamp pole structure and a desk lamp. Background Art

[0002] A desk lamp generally refers to an electric lamp with a base that is placed on a table. The main function of a desk lamp is lighting, which is convenient for reading, studying, working, etc. The light range of the desk lamp is relatively small and concentrated, so it will not affect the light of the entire room. The effect is limited to the area around the desk lamp, which is convenient for reading, studying, writing, and saving energy. The desk lamp pole is one of the important components of the entire desk lamp.

[0003] However, there are various types of desk lamp poles in the prior art. For example, utility model patent CN204062634U relates to a detachable double-lamp head and double-lamp pole desk lamp. The utility model includes a first lamp head, a second lamp head, a first lamp pole, a second lamp pole and a lamp holder. The first lamp head is provided with a first lamp head, the second lamp head is provided with a second lamp head, and the lamp holder includes a fixed part and a movable part. The first lamp head is connected to the fixed part through the first lamp pole, and the second lamp head is connected to the movable part through the second lamp pole. The first lamp head is movably connected to the first lamp pole. The utility model solves the problem of two people using the desk lamp at the same time through the structural design of double lamp heads and double lamp poles, and the desk lamp can be split into two separate desk lamps through the fixed part and the movable part of the lamp holder, which solves the problem of resource waste when one person uses the desk lamp.

[0004] Although the desk lamp can be used by two people at the same time and solves the resource waste when used by one person, the lamp pole of the desk lamp is fixed in structure during use, the length of the lamp pole is usually not convenient to adjust, and the range of light exposure is difficult to change, which is not conducive to meeting the personalized needs of customers. At the same time, a desk lamp that is too high has poor stability due to the lack of a fixed structure. In order to avoid this phenomenon, it is very necessary to design a retractable desk lamp pole structure and a desk lamp. Utility Model Content

[0005] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0006] To achieve the above-mentioned purpose, the present invention provides a retractable desk lamp pole structure and a desk lamp, which are achieved by the following specific technical means:

[0007] A retractable desk lamp pole structure includes a telescopic sleeve, which is fixed on a supporting base. A guide column is slidably installed inside the telescopic sleeve. One end of the guide column is fixedly connected to a movable lamp pole, and one end of the movable lamp pole extends outside the telescopic sleeve. A plurality of positioning holes are provided on the surface of the movable lamp pole. A threaded sleeve is provided through the telescopic sleeve. A threaded limit rod is threadedly connected to the inner surface of the threaded sleeve, and the end of the threaded limit rod matches the positioning hole. One end of the threaded limit rod is fixedly connected to an adjustment disk. One side of the supporting base is rotatably connected to a fixed bracket via a rotating shaft, and the fixed bracket is C-shaped. A splint is provided inside the fixed bracket for lifting and lowering.

[0008] Preferably, the fixed bracket can be flipped under the rotation of the rotating shaft. A threaded ring is provided through the fixed bracket. The inner surface of the threaded ring is threadedly connected to a screw, and one end of the screw is movably connected to the splint. The end of the screw away from the splint is fixedly connected to an adjustment handle, and the adjustment handle is located below the fixed bracket.

[0009] Preferably, a sliding groove is provided on the inner wall of the fixed bracket, a guide block is fixedly connected to one side of the clamping plate, and the guide block is slidably installed in the sliding groove.

[0010] Preferably, when the threaded limiting rod is tightened, the end of the threaded limiting rod can be embedded in the interior of any matching positioning hole.

[0011] Preferably, an extension plate is provided on the other side of the support base, the top of the extension plate is fixedly connected to a placement frame, and the placement frame is fixed to one side of the telescopic sleeve, a speaker can be snapped into the placement frame, and a wireless charger is installed on the top of the speaker.

[0012] The utility model also provides a desk lamp, comprising a retractable desk lamp pole structure and a support column fixed to the top end of the movable lamp pole, wherein a connecting rod is fixed to the top end of the support column.

[0013] Preferably, one end of the connecting rod is fixedly connected to a lampshade, the connecting rod is located inside the lampshade, and a lighting lamp is detachably installed inside the lampshade, and the lighting lamp is ring-shaped.

[0014] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0015] When using the desk lamp, the user can pull out the movable lamp pole according to the actual needs of the user, and then tighten the adjustment dial to screw the end of the threaded limit rod into the positioning hole, thereby adjusting the length of the desk lamp pole after extension and retraction. When the desk lamp is placed on a high table or bedside table, and the lamp pole is not fixed during the extension and retraction process, the stability of the desk lamp is affected. The fixed bracket is flipped downward by the rotating axis, and the edge of the table or cabinet is inserted into the fixed bracket. The adjusting handle is then shaken to make the screw drive the splint toward the edge of the table or cabinet, so that the splint is used to clamp the fixed bracket, ensuring that the entire desk lamp is stably placed on the table or bedside table, thereby improving the stability of the entire desk lamp during extension and retraction.

The present invention provides the following embodiments.

[0027] Example 1:

[0028] like Figure 1 、 Figure 2 as well as Figure 3 As shown, it is a structural schematic diagram of the telescopic table lamp pole structure in this embodiment. The table lamp pole structure in this embodiment includes a telescopic sleeve 2, which is fixed on the supporting base 1. A guide column 3 is slidably installed inside the telescopic sleeve 2. One end of the guide column 3 is fixedly connected to a movable lamp pole 4, and one end of the movable lamp pole 4 extends outside the telescopic sleeve 2. A plurality of positioning holes 5 are opened on the surface of the movable lamp pole 4. A threaded sleeve 6 is provided through the telescopic sleeve 2. The inner surface of the threaded sleeve 6 is threadedly connected to a threaded limiting rod 7, and the end of the threaded limiting rod 7 matches the positioning hole 5.
