Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to an improved combined lamp. Background Art

[0002] Class I lighting fixtures refer to those that rely on grounding for safety protection, that is to say, the input wires consist of three wires, namely: live wire, neutral wire, and ground wire, and the outer casing of the lamp is connected to the ground wire. Class II lighting fixtures do not have grounding wires, and the input wires only have live wire and neutral wire, and safety protection is protected by the insulator outside the lamp. Class III lighting fixtures have low voltage input, and the main types of lamps with input DC voltage below 36V are chandeliers, floor lamps, wall lamps, table lamps, etc.

[0003] There are many types of combined lamps on the market. For example, the Chinese patent, announcement number CN219571828U, is a combined lamp that is easy to load and unload. This technical solution rotatably connects the main rod and the base through the cooperation of a rotating part, and makes the auxiliary rod and the main rod adjustably connected through an adjusting part. When adjusting, the rotation of the main rod is limited by the clamping of the limit member, and the rotation of the auxiliary rod is adjusted by the adjusting member. The restrictions on the main rod and the auxiliary rod are hard restrictions, which reduces the possibility of limit failure and increases the practicality of the device. However, this technical solution still has some shortcomings. For example, this technical solution does not have a height adjustment function, and only relies on the adjusting member to adjust the angle of the table lamp. The adjustment angle is also relatively limited, which cannot meet the work or study needs of people of different ages. In addition, the lighting equipment of this technical solution still uses traditional socket power supply. If there is a power outage or the wires are accidentally touched, the table lamp will be powered off, which is very inconvenient during use. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-Figure 6 In this embodiment, an improved combined lamp comprises a support rod 1, a lifting mechanism 2 is arranged inside the support rod 1, and an adjustment mechanism 3 is arranged on the top of the lifting mechanism 2;

[0025] The lifting mechanism 2 includes a first bearing 201, and two first bearings 201 are fixedly installed on the inner wall of the support rod 1. The inner walls of the two first bearings 201 are fixedly connected with a rotating rod 202 extending to the outside of the support rod 1. When the rotating rod 202 rotates, the two bearings 201 can provide stronger stability for the rotation of the rotating rod 20. One end of the two first rotating rods 202 extending to the outside of the support rod 1 is fixedly installed with a first hand wheel 203, and the hand wheel 203 can drive the rotating rod 202 to rotate. A gear 204 is fixedly installed on the rotating rod 202, and a rack 205 is movably installed in the support rod 1. The rack 205 can slide up and down, and the gear 204 and the rack 205 are meshed with each other. Through the relationship between the gear 204 and the rack 205, the rotation of the gear 204 will drive the rack 205 to move up and down, thereby changing the height of the entire desk lamp, and the operation is also relatively convenient. A first external threaded column 206 is fixedly installed on the top of the rack 205, which is convenient for active connection with other structures;

[0026] The adjusting mechanism 3 includes an adjusting tube 301, a first external threaded column 206 is threadedly connected to the adjusting tube 301, second bearings 302 are fixedly installed on both left and right ends of the inside of the adjusting tube 301, and the inner walls of the two second bearings 302 are fixedly connected with threaded sleeves 303 extending to the outside of the adjusting tube 301. Similar to the principle of the first bearing 201, the second bearing 302 can also make the threaded sleeve 303 rotate stably, and a second hand wheel 304 is fixedly installed on one end of the threaded sleeve 303 extending to the outside of the adjusting tube 301, and the threaded sleeve 303 can be driven to rotate by turning the second hand wheel 304. A limiting block 305 is fixedly installed on the outside of the adjusting tube 301 for convenient connection with other structures.

[0027] In the case implementation, the internal thread of the threaded sleeve 303 is connected to the threaded rod 4, the right side of the threaded rod 4 is detachably connected to the connecting rod 5, and the right side of the connecting rod 5 is detachably connected to the lampshade 6. When the threaded sleeve 303 rotates, it will drive the threaded rod 4 to move left and right. When the threaded rod 4 moves, it will also drive the connecting rod 5 and the lampshade 6 to move left and right. In this way, the purpose of translation of the lampshade 6 can be achieved, and the horizontal length can be freely adjusted as needed.

[0028] In the implementation case, the bottom of the support rod 1 is movably connected with a second externally threaded column 10, and the outside of the second externally threaded column 10 is movably connected with a rotation damper 7, and the outside of the rotation damper 7 is provided with a second threaded hole adapted to the second externally threaded column 10, so that the rotation damper 7 can be connected to the support rod 1. The rotation damper 7 is a cylinder.

[0029] In the case implementation, a first threaded hole compatible with the first external threaded column 206 is opened at the bottom of the adjusting tube 301, which can connect the adjusting tube 301 and the first external threaded column 206, and also realize the quick assembly and disassembly function of the two structures.

[0030] In the case implementation, a fixing block 11 is detachably mounted on the top of the connecting rod 5, a support 12 is fixedly mounted on the top of the fixing block 11, a guide rod 13 is hinged on the support 12, a through hole matching the guide rod 13 is provided on the limit block 305, the guide rod 13 slides with the through hole, and the guide rod 13 can provide fixing and guiding functions for the connecting rod 5, a circuit board 14 is fixedly mounted inside the lampshade 6, a battery 15 is fixedly mounted on the top of the circuit board 14, which can store electricity, an LED lamp 16 is clamped on the bottom of the circuit board 14, a charging port 17 is arranged on the outside of the lampshade 6, and the battery 15 can be directly charged through a charging line, and a control switch 18 is fixedly mounted on the outside of the lampshade 6, so as to facilitate the operation of the control switch 18 to control the operation of the electronic components. The circuit board 14 is electrically connected to the battery 15, the LED lamp 16, the charging port 17, and the control switch 18, and this is a prior art, which will not be repeated here.

[0031] In the case implementation, a mounting platform 8 is fixedly installed at the bottom of the rotating damper 7, which can provide strong support for the entire table lamp structure. A plurality of adsorption plates 9 are arranged at the bottom of the mounting platform 8, which can be fixed on the wall, cabinet door or desktop according to one's needs, and can also provide strong stability.

[0032] When implementing, follow these steps:

[0033] 1) First, fix the desk lamp by using the suction plate 9 at the bottom of the placement table 8;

[0034] 2) Then adjust the lifting mechanism 2 as needed to adjust the height of the desk lamp to a satisfactory height;

[0035] 3) Operate the adjustment mechanism 3 again to translate the lampshade 6 to the target position;

[0036] 4) Finally, turn on the control switch 18 on the lampshade 6 to make the LED lamp 16 produce light.

[0037] In summary, the combined lamp, by setting the lifting mechanism 2 and the adjusting mechanism 3, first rotates the first hand wheel 203 to drive the rotating rod 202 to rotate, and at the same time, the two first bearings 201 on the inner wall of the support rod 1 can provide stronger stability for the rotation of the rotating rod 202, so that the rotating rod 202 can rotate stably, and the stable rotation of the rotating rod 202 drives the gear 204 to rotate. Through the mutual meshing relationship between the gear 204 and the rack 205, the rotation of the gear 204 will drive the rack 205 to move to the upper and lower ends, and the movement of the rack 205 will drive the adjusting mechanism 3 above the rack 205 to move. After reaching the ideal height, the second hand wheel 304 is rotated, and the threaded sleeve 303 is driven to rotate by the second hand wheel 304, and the first bearing The principle of the second bearing 302 is similar to that of the first bearing 201. The second bearing 302 can also make the threaded sleeve 303 rotate stably. Since the threaded rod 4 is connected to the limit block 305 by the sliding connection relationship through the guide rod 13, the threaded rod 4 will not rotate. Therefore, when the threaded sleeve 303 rotates, the threaded rod 4 will move left and right. When moving, it will also drive the lampshade 6 next to it to move left and right. Thus, the purpose of adjusting the multi-directional adjustment is achieved. It can be convenient for people of different heights to use it. It has strong applicability. At the same time, the overall structure can also be quickly loaded and unloaded, which is very convenient to use. It solves the problem that the existing technical solution has no height adjustment function and only relies on the adjustment member to adjust the angle of the desk lamp. The adjustment angle is also relatively limited and cannot meet the work or study needs of people of different ages. In this embodiment, a mechanism for adjusting the angle in the prior art can also be installed between the rack 205 and the adjustment tube 301 to achieve angle adjustment.

[0038] Moreover, by providing the storage battery 15 and the charging port 17, electricity can be stored in the storage battery 15 through the charging port 17. When the charging line is unplugged, the storage battery 15 can be used to power the LED lamp 16, so that the lighting of the table lamp is more stable during use, which solves the problem that the lighting equipment of the technical solution is still powered by the traditional socket. If there is a power outage or the wire is accidentally touched, the table lamp will be powered off, which is very inconvenient during use. In addition, the combined lamp adopts a modular design, the support rod 1 and the lifting mechanism 2 are assembled in the factory, the adjustment mechanism 3 is also a standard part produced by the factory, the lampshade 6 and the circuit board 14 thereon, the storage battery 15, the LED lamp 16, the charging port 17, and the control switch 18 are also assembled in the factory, the fixing block 11, the support 12 and the guide rod 13 have been assembled in the factory, and the other small parts: the suction plate 9, the placement table 8, the rotation damper 7, and the threaded rod 4 do not take up space. Therefore, the combined lamp is convenient for transportation and easy for users to install and disassemble.
