Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting technology, and in particular to a height adjustment device and a lighting lamp. Background Technology
[0002] In the field of eye-protection lighting equipment, especially in vertical streetlights, the ability to flexibly adjust the lamp head height to meet the lighting needs of different usage scenarios (such as reading, working, and leisure) is an important function. Traditional eye-protection streetlights generally use a mechanical lifting structure to achieve height adjustment. This type of structure usually relies on a complex gear transmission mechanism combined with a screw locking method for fixation.
[0003] However, this traditional lifting solution has significant shortcomings. The core problem lies in the complexity and bulkiness of the lifting structure, leading to cumbersome operation, large space occupation, and limited adaptability. Specifically, the complex gear assembly itself occupies a large physical space, while the internal space of the support pole for streetlights is typically limited and elongated. This makes the installation and layout of the gear transmission mechanism difficult and cramped, increasing the complexity of the product's internal design and assembly difficulty. More importantly, when users need to adjust the lamp head height according to actual usage scenarios (e.g., switching from desktop work to standing activity), they must use additional specialized tools (such as screwdrivers or wrenches) to loosen the fixing screws, operate the gear mechanism to raise or lower, and then tighten the screws again to secure it after reaching the target height. This series of operations is cumbersome and time-consuming, extremely inconvenient for users, and greatly reduces the product's usability and user experience. Furthermore, this reliance on tools means that height adjustment cannot be performed quickly and manually at any time, greatly limiting the product's immediate adaptability and flexibility across different application scenarios. Therefore, we provide a height adjustment device and lighting fixture to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a height adjustment device and a lighting lamp.
[0005] The objective of this utility model is achieved through the following technical solution:

[0034] like Figure 1 — Figure 7 The example shown.
[0035] This application provides a height adjustment device, which includes a fixed rod 100, a driven rod 200, a hanging member 300, and an elastic member 400.
[0036] In some specific embodiments, a limiting member 110 is fixedly installed on the top circumferential surface of the fixed rod 100, an mounting member 120 is fixedly installed in the fixed rod 100, the driven rod 200 is located at the top of the fixed rod 100, the driven rod 200 is slidably connected to the fixed rod 100, the mounting member 120 is slidably disposed in the driven rod 200, the hanging member 300 is detachably fixedly disposed in the driven rod 200, the elastic member 400 is fixedly installed on the mounting member 120, and the other end of the elastic member 400 is disposed on the hanging member 300.
[0037] Please see Figure 1 and Figure 2 as well as Figure 6 As shown, both the fixed rod 100 and the driven rod 200 have a through central slot, meaning that the interiors of both the fixed rod 100 and the driven rod 200 are through structures. A portion of the fixed rod 100 is slidably disposed within the driven rod 200, while the mounting member 120 forms a sliding connection with the driven rod 200.
[0038] In this embodiment, one end of the elastic element 400 is fixedly connected to the mounting member 120, and the other end is hung on the hanging member 300, which is fixedly connected to the driven rod 200. Thus, the elastic element 400 applies an upward pulling force to the driven rod 200, which is balanced by the total weight of the driven rod 200 and all components mounted on it. Therefore, the height of the driven rod 200 remains stable and unchanged when no external force is applied. When the height of the lamp head 20 needs to be adjusted, since the pulling force provided by the elastic element 400 is precisely equal to the total weight of the driven rod 200 and its supporting components, the operator only needs to apply a small external force to drive the driven rod 200 to move vertically. This movement directly adjusts the height of the lamp head 20 mounted on the driven rod 200, ultimately achieving stepless adjustment of the lighting height.
[0039] In this embodiment, the elastic element 400 is a coil spring. Alternatively, the elastic element 400 can also be a spring or other elastic component. The specific patent is not limited, as long as its tension or elastic force is equal to the driven rod 200 and the weight mounted on it.
[0040] In some specific embodiments, a hanging groove 210 is provided on the end frame of the driven rod 200 facing the fixed rod 100, the hanging member 300 is hung on the hanging groove 210, and the end of the elastic member 400 facing away from the mounting member 120 is hung on the hanging member 300.
[0041] Please continue reading. Figure 1 and Figure 2 As shown, in some specific embodiments, a hanging groove 210 is provided on the end frame of the driven rod 200 facing the fixed rod 100, and the hanging member 300 is hung on the hanging groove 210, thereby realizing the fixed connection between the hanging member 300 and the driven rod 200, so as to effectively transmit the tension from the elastic member 400 to the driven rod 200 and complete the force transmission process.
[0042] In some specific embodiments, the hanging member 300 includes a plate 310, a first hanging plate 320 is fixedly disposed on one side of the plate 310, the first hanging plate 320 is hung on the hanging groove 210, a second hanging plate 330 is disposed on the side of the plate 310 opposite to the first hanging plate 320, and a hanging opening is disposed at one end of the elastic member 400 opposite to the direction of the mounting member 120, the hanging opening is hung on the second hanging plate 330.
[0043] Please see Figure 1 and Figure 3 As shown, a first hanging plate 320 is integrally formed on one side of the plate 310, and a U-shaped groove is defined between the first hanging plate 320 and the plate 310. The side wall portion of the driven rod 200 at the hanging groove 210 extends into this groove, thus fixing the hanging member 300 on the driven rod 200. Furthermore, the side wall of the driven rod 200 can be interference-fitted with the groove to prevent the plate 310 from separating from the driven rod 200. A second hanging plate 330 is also integrally formed on the side of the plate 310 opposite to the first hanging plate 320. The hanging opening on the other end of the elastic member 400 is attached to the second hanging plate 330, thereby achieving a transmission connection between the plate 310 and the elastic member 400.
[0044] In some specific embodiments, the limiting member 110 includes a connecting ring 111 formed on the top circumferential surface of the fixing rod 100, the connecting ring 111 having a clearance hole 113, and an abutment ring 112 fixedly disposed on the side wall of the connecting ring 111.
[0045] A plug 220 is fixedly installed at the end of the driven rod 200 facing the fixed rod 100. The plug 220 includes a sleeve ring 221. At the position of the hanging member 300, the plug 220 is provided with a relief groove 2210. A cover plate 2211 is provided at the end of the inner wall of the sleeve ring 221. A reinforcing plate 222 is provided on the cover plate 2211. At the position of the relief groove 2210, an abutment plate 2220 is provided on the reinforcing plate 222. The side wall of the abutment plate 2220 abuts against the hanging member 300.
[0046] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in some specific embodiments, a cap 220 is fixedly installed at the end of the driven rod 200, and a limiting member 110 is installed at the end of the fixed rod 100. When an upward force is applied to the driven rod 200 to move it upward for height adjustment, as the driven rod 200 moves upward, the cap 220 fixed at its end will eventually abut against the limiting member 110 at the end of the fixed rod 100, thereby limiting the maximum upward stroke of the driven rod 200 and preventing the driven rod 200 from separating from the fixed rod 100 due to excessive movement distance.
[0047] Specifically, during the upward movement of the driven rod 200, which in turn moves the plug 220, when the driven rod 200 reaches a specific height, the sleeve ring 221 of the plug 220 abuts against the abutment ring 112 of the limiting member 110, thereby limiting the movement distance of the driven rod 200. The connecting ring 111 of the limiting member 110 has a clearance hole 113, which provides a channel for the driven rod 200 to move upward, preventing interference between the driven rod 200 and the connecting ring 111.
[0048] Furthermore, a reinforcing plate 222 is provided on the cover plate 2211 of the sleeve ring 221, and an abutment plate 2220 is integrally formed on the reinforcing plate 222. The side wall of the abutment plate 2220 abuts against the plate body 310 of the hanger 300, restricting the plate body 310 between the inner wall of the driven rod 200 and the side wall of the abutment plate 2220; at the same time, the bottom of the plate body 310 contacts the upper surface of the cover plate 2211. Through the limiting space formed by the cover plate 2211, the abutment plate 2220 and the inner wall of the driven rod 200, displacement of the plate body 310 and separation from the driven rod 200 are effectively prevented, thus achieving reliable limitation of the position of the hanger 300.
[0049] In some specific implementations, the mounting component 120 includes a mounting plate 121, one end of which is fixedly mounted with a connecting block 122. The connecting block 122 is fixedly mounted in the fixing rod 100. A limit strip 123 is fixedly mounted on the end of the mounting plate 121 opposite to the connecting block 122. The limit strip 123 is slidably disposed in the driven rod 200.
[0050] Please see Figure 1 and Figure 2 When it is necessary to adjust the height of the driven rod 200 downwards, a downward force is applied to the driven rod 200. During the downward movement of the driven rod 200, the plug 220 is moved downwards simultaneously. When the driven rod 200 descends to a certain distance, the plug 220 will abut against the connecting block 122 of the mounting member 120, at which point the driven rod 200 reaches its maximum downward stroke.
[0051] To ensure the smooth up-and-down movement of the driven rod 200, a limit strip 123 is fixedly installed on the top of the mounting plate 121 of the mounting component 120; the limit strip 123 and the driven rod 200 form a sliding connection, and under the combined action of the two, the lifting and lowering process of the driven rod 200 is ensured to be stable and smooth.
[0052] Please see Figure 6 and Figure 7 As shown in the embodiment of this application, a lighting lamp is also provided. The lighting lamp includes a base plate 10, a lamp head 20, and any of the height adjustment devices described above. Specifically, the lamp head 20 is located above the base plate 10, the fixing rod 100 is fixedly installed on the base plate 10, and the lamp head 20 is fixedly installed on the driven rod 200.
[0053] When the height of the lamp head 20 needs to be adjusted, the height of the driven rod 200 can be adjusted to achieve the height adjustment of the lamp head 20.
[0054] The working process of this utility model is as follows: When the user applies external force to the driven rod 200, the driven rod 200 slides along the fixed rod 100, causing the lamp holder 20 fixed thereon to rise and fall. The inner end of the elastic element 400 is fixed to the mounting plate 121 of the mounting member 120, and the outer end is hung on the second hanging plate 330 of the hanging member 300 through the hanging opening. The hanging member 300 is hung in the hanging groove 210 at the end of the driven rod 200 through the first hanging plate 320, so that the elastic force of the elastic element 400 is transmitted to the driven rod 200. The elastic force of the elastic element 400 is balanced with the weight of the driven rod 200 and the lamp holder 20, so that the driven rod 200 remains highly stable when there is no external force. When the driven rod 200 rises to its limit position, the sleeve ring 221 of the plug 220 abuts against the abutment ring 112 of the limiting member 110; when the driven rod 200 descends to its limit position, the plug 220 abuts against the connecting block 122 of the mounting member 120, thus limiting the stroke. The limiting strip 123 of the mounting member 120 slides within the driven rod 200 to ensure smooth lifting. The abutment plate 2220 and cover plate 2211 of the plug 220 restrict the displacement of the plate 310 of the hanging member 300, preventing it from dislodging from the hanging groove 210. The clearance hole 113 of the limiting member 110 provides a movement channel for the driven rod 200, and the clearance groove 2210 of the plug 220 provides installation space for the hanging member 300.
[0055] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
