DETAILED DESCRIPTION

[0037] 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.

[0038] See attached Figure 1 -Attached Fig.10 A telescopic adjustable lamp comprises a lamp body 1, a base 2, a telescopic member 3 and a metal hose 4; a riser 21 is detachably mounted on the base 2, a power supply terminal 20 is mounted inside the riser 21, and the power supply terminal 20 is connected with a power line 201 penetrating to the outside and a power supply wire 202 located in the riser 21; the telescopic member 3 comprises an outer tube 31, an inner tube 32 and a limiting portion 33, the outer tube 31 is slidably sleeved on the inner tube 32, and the outer tube 31 is detachably connected to the riser 21, and the limiting portion 33 is mounted on the outer tube 31 and can limit the movement of the inner tube 32; the lamp body 1 is mounted on the head end of the metal hose 4, the tail end of the metal hose 4 is connected to the inner tube 32, and a conductive terminal 40 electrically connected to the lamp body 1 is also mounted on the tail end of the metal hose 4; the power supply wire 202 is routed along the pipelines of the outer tube 31 and the inner tube 32, and is electrically connected to the conductive terminal 40.

[0039] Specifically, during assembly, the power supply wire 202 located in the vertical pipe 21 is sequentially inserted into the outer tube 31 and the inner tube 32 to the conductive end 40 for connection, and then the outer tube 31 is installed on the vertical pipe 21, and the metal hose 4 is installed on the inner tube 32, so that the lamp body 1 can be supported at a corresponding height position; when in use, the restriction of the inner tube 32 by the limiting part 33 is released, and the inner tube 32 is moved along the length direction of the outer tube 31 and then restricted by the limiting part 33, so that the lamp body 1 can be stopped at the current height position, and by bending the metal hose 4 to change its shape, the lamp body 1 can be stopped at the current angle position.

[0040] It should be noted that the length of the power supply wire 202 is generally fixed, and its total length should be able to meet the total stroke of the telescopic member 3. If the telescopic range of the inner tube 32 is shorter, the remaining power supply wire 202 will remain in the outer tube 31 and will not affect the normal use of the telescopic member 3.

[0041] In summary, the utility model improves portability by designing the base 2, the vertical tube 21, the telescopic part 3 and the metal hose 4 to be detachably connected to facilitate transportation and transfer before assembly; the design of the telescopic part 3 makes it convenient for users to adjust the height position of the lamp body 1, and the design of the metal hose 4 makes it convenient for users to adjust the angle position of the lamp body 1. The combined use of the two improves the user experience.

[0042] See attached Figure 1 -Attached Fig.10 The utility model also includes at least one support tube 5, which is located between the vertical tube 21 and the telescopic member 3, and the two ends of the support tube 5 are detachably connected to the vertical tube 21 and the outer tube 31 respectively. The power supply wire 202 is routed along the pipeline of the support tube 5 and then enters the pipelines of the outer tube 31 and the inner tube 32.

[0043] Specifically, during assembly, a corresponding number of support tubes 5 are selected according to needs, and the power supply wire 202 located in the vertical tube 21 is inserted into each support tube 5, the outer tube 31 and the inner tube 32 in turn to connect to the conductive end 40, and then the support tube 5 is installed on the vertical tube 21, the outer tube 31 is installed on the support tube 5, and the metal hose 4 is installed on the inner tube 32, so that the lamp body 1 can be supported at a corresponding height position.

[0044] Normally, the height position of the lamp body 1 can be slightly adjusted by moving the inner tube 32 along the direction of the outer tube 31. If the stroke of the telescopic member 3 is insufficient, the height position of the lamp body 1 can be greatly adjusted by increasing the number of support tubes 5. Therefore, the coordinated use of the telescopic member 3 and the support tubes 5 can further improve the convenience of use.

[0045] It should be noted that the length of the power supply wire 202 is generally fixed, and its total length should be able to meet the needs of multiple support tubes 5 and telescopic parts 3 for simultaneous assembly and use. If the overall length after assembly is shorter, the remaining power supply wire 202 will remain in the support tube 5 and the telescopic part 3, and will not affect normal use.

[0046] See attached Figure 6 -Attached Fig.10Regarding the connection method between the riser 21, the support tube 5 and the outer tube 31, a snap connection, a threaded connection, etc. can be adopted, and the present invention does not limit this. For the convenience of understanding, the present invention also includes a connecting block 6, which is hollow inside and has threads on the outside, and there are multiple connecting blocks 6; the riser 21, the support tube 5 and the outer tube 31 are all threadedly connected to the connecting block 6. Through the design of multiple connecting blocks 6, the riser 21 and the support tube 5, the support tube 5 and the outer tube 31, and the riser 21 and the outer tube 31 can be spliced ​​with each other, thereby improving the convenience of assembly.

[0047] See attached Figure 7 and attached Fig.10 Regarding the connection method between the base 2 and the vertical pipe 21, as well as the connection method between the metal hose 4 and the inner pipe 32, snap connection, threaded connection, etc. can be adopted. There is no restriction on this in the utility model. For the convenience of understanding, a connecting column 22 with an external thread is installed on the base 2, and the connecting column 22 is threadedly connected to the vertical pipe 21; the tail end of the metal hose 4 is externally threaded and threadedly connected to the inner pipe 32.

[0048] See attached Figure 4 and attached Figure 8 -Attached Fig.11 The limiting portion 33 includes a block 331 and a rotary sleeve 332. The block 331 is installed on the outer tube 31, and a through hole 3311 is provided inside the block 331 for the inner tube 32 to slide through. A plurality of deformable claws 3312 are provided at the top edge of the through hole 3311; the rotary sleeve 332 is threadedly connected to the block 331, and twisting the rotary sleeve 332 can drive the plurality of claws 3312 to squeeze or loosen the side wall of the inner tube 32, so as to lock the inner tube 32 on the outer tube 31 or release the restriction on the inner tube 32.

[0049] Specifically, when adjusting the length of the telescopic member 3 , the rotary sleeve 332 is loosened so that the multiple claws 3312 release the side wall of the inner tube 32 , and then the inner tube 32 is moved, and finally the rotary sleeve 332 is tightened so that the multiple claws 3312 squeeze the side wall of the inner tube 32 .

[0050] It should be noted that, in addition to the above-mentioned structure, the telescopic member 3 and the outer tube 31 and the inner tube 32 may also adopt other limiting parts 33. Since the relevant technology is relatively conventional in the mechanical field, they are not listed one by one in the utility model.

[0051] See attached Figure 2 and attached Figure 6 -Attached Fig.10 , the power supply wire 202 is a spring cable; the spring cable is also called a spiral cable, which has good flexibility and elasticity (the elongation length can reach 3.5-4 times the original spring length).

[0052] Specifically, when the support tube 5 is not used, the spring cable is contracted in the vertical tube 21 and the outer tube 31, and is stretched and expanded when the inner tube 32 moves, and the spring cable is automatically adapted according to the moving height of the inner tube 32; when the support tube 5 is used, the spring cable is contracted in the vertical tube 21 and the support tube 5, and when multiple support tubes 5 are assembled or the inner tube 32 is moved, the spring cable can be automatically adapted according to the total length of the assembly and the telescopic length of the telescopic member 3;

[0053] Therefore, the power supply wire 202 adopts a spring cable, which can be adapted according to the overall height during assembly, and has a certain tension as a whole to avoid accumulation and blockage of the outer tube 31 or the inside of the support tube 5; after disassembly, it will automatically shrink to control the initial length to be very short to avoid the wires from being tangled.

[0054] It should also be noted that the connection method between the power supply wire 202 and the power supply terminal 20 and the conductive terminal 40 can be fixed by screws or by a plug-in socket connection method. This is not limited in the present invention, but it is necessary to ensure that the connection force between the power supply wire 202 and the power supply terminal 20 and the conductive terminal 40 is greater than the elastic force of the spring cable to prevent the power supply wire 202 from shrinking and detaching from the power supply terminal 20 and the conductive terminal 40.

[0055] See attached Figure 3 -Attached Figure 6 Considering that if too many supporting tubes 5 are assembled or the length of the telescopic member 3 is extended too long, the overall center of gravity may be unstable and may tip over. To solve this problem, a storage groove 23 is also provided on the base 2. By installing a counterweight block (not shown in the figure) in the storage groove 23, the bearing capacity of the base 2 can be increased to avoid the overall tipping over.

[0056] See attached Figure 3 -Attached Figure 6 The bottom surface of the base 2 is provided with an anti-sliding block 24 in contact with the ground. This design can increase the friction and adsorption force between the base 2 and the bottom surface, thereby preventing the base 2 from slipping and improving the supporting capacity of the base 2.

[0057] See attached Figure 8 -Attached Fig.12 The metal hose 4 is an existing product. After being changed in shape by an external force, it will maintain its current state, so it has good shaping ability; the metal hose 4 is made of various materials, such as copper, aluminum, memory metal, etc., which are not limited in the present utility model; for the sake of ease of understanding, in this embodiment, the metal hose 4 is preferably made of memory metal material. Memory metal has a large bending capacity, a poor service life, and high plasticity, which can meet the angle adjustment of the lamp body 1 in various directions.

[0058] See attached Figure 5 and attached Fig.12 There are various types of lamp bodies 1, for example, conventional lamps or focusing lamps can be used. In the present invention, focusing lamps are preferably used. Currently, most focusing lamps on the market have complex structures, which not only have high production costs but also are inconvenient to operate. For this reason, in the present invention, the lamp body 1 includes a lamp holder 11, a lamp cover 12 and a rubber ring 13; a guide column 111 is installed on the lamp holder 11, and a light-emitting body 110 is provided at the end of the guide column 111; the lamp cover 12 is slidably mounted on the guide column 111, and a light-expanding lens 120 corresponding to the light-emitting body 110 is installed on the lamp cover 12; the rubber ring 13 is installed on the guide column 111 and abuts against the inner wall of the lamp cover 12, so that there is damping between the lamp cover 12 and the lamp holder 11.

[0059] Specifically, when in use, the lamp cover 12 is pulled along the direction of the guide column 111 to make the light expanding lens 120 move away from or close to the light source 110, so as to realize the free conversion of focusing and flooding; and the design of the rubber ring 13 makes the lamp cover 12 and the lamp holder 11 have damping, so as to improve the operating feel while preventing the lamp cover 12 from shaking.

[0060] It should also be noted that, although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
