Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures, and in particular to a telescopic lamp holder and the lighting fixture thereof. Background Technology

[0002] In modern life and work scenarios, lighting equipment has become an indispensable infrastructure, and the structural design of the lamp holder, as the core supporting component of the lamp, directly affects the flexibility of the lamp's use, the range of applicable scenarios, and the space utilization rate.

[0003] Traditional lamp holders typically use a fixed, integrated structure, and their length cannot be adjusted after manufacturing. This leads to several problems in practical applications: when lighting large spaces (such as living rooms or showrooms), fixed, short lamp holders cannot meet the needs of wide-area lighting coverage, requiring additional lamps, which not only increases operating costs but may also lead to messy wiring and affect the aesthetics of the space; while in small spaces (such as bedrooms or bathrooms), excessively long fixed lamp holders occupy too much space, easily interfering with other furniture or equipment, and reducing space utilization. Furthermore, fixed-size lamp holders are inconvenient to pack and store, increasing the difficulty of transportation and storage. Utility Model Content

Detailed Implementation

[0017] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0018] Reference Figures 1 to 7 In the first embodiment of this solution, a retractable lamp holder includes a fixed tube 1. First sliding grooves 11 are provided at both ends of the fixed tube 1 along its length. Each of the left and right ends of the first sliding grooves 11 contains a first movable tube 2 that can move left and right along the first sliding grooves 11. The fixed tube 1 is provided with a first limiting component 12 that can prevent the first movable tube 2 from disengaging from the first sliding grooves 11. The first limiting component 12 can also be used to position the first movable tube 2, allowing it to be moved to a suitable position for use. This allows for adjustment of the lamp holder's length, which can then be adjusted according to actual usage, improving its applicability. Furthermore, during transportation, the lamp holder can be retracted to its shortest length, avoiding excessive packaging and increased shipping costs, thus facilitating transportation and storage.

[0019] Reference Figure 2 and Figure 3A gap exists between the outer wall of the first movable tube 2 and the inner wall of the first sliding groove 11, facilitating the movement of the first movable tube 2 within the first sliding groove 11. The width of this gap is preferably 0.3-3 mm, adjustable according to the diameter of the first movable tube 2 to prevent the first movable tube 2 from wobbling within the groove due to an excessively large gap. A first sleeve 21, abutting against the inner wall of the first sliding groove 11, is provided at one end of the first movable tube 2 inserted into the first sliding groove 11. This first sleeve 21 abuts against the first limiting component 12 to prevent the first movable tube 2 from falling off. The first sleeve 21 is T-shaped and fixed to the first movable tube 2 by adhesive or screw fastening.

[0020] Furthermore, the first limiting component 12 includes a second collar 121 fitted onto the left and right ends of the fixed tube 1, and a first plastic ring 122 embedded within the second collar 121. The second collar 121 can be fixed to the first movable tube 2 by adhesive or screw locking. The inner diameter of the first plastic ring 122 is smaller than the outer diameter of the first movable tube 2 by 0.05-1mm. This is adaptively adjusted according to the diameter of the first movable tube 2. The slight elastic deformation generated by the plastic ring can provide a certain damping force for the first movable tube 2, preventing it from sliding on its own without human intervention, without affecting normal telescopic adjustment, and also enabling stepless adjustment of the extension length of the first movable tube 2. At the same time, the first plastic ring 122 abuts against the first collar 21, preventing the first movable tube 2 from detaching from the first sliding groove 11. In addition, the inner edge of the first plastic ring 122 is rounded, and its material is relatively soft, which can avoid scratching the outer wall of the first movable tube 2 and avoid damaging the overall appearance of the lamp holder.

[0021] Preferably, both the first set of rings 21 and the second set of rings 121 can be made of metal or plastic.

[0022] Reference Figures 4 to 6 In the second embodiment of this solution, a second sliding groove 22 is provided at the extended end of the first moving tube 2 along its length. Each of the second sliding grooves 22 contains a second moving tube that can move left and right along the groove. A second limiting component 23 is provided on the first moving tube 2 to prevent the second moving tube from disengaging from the second sliding groove 22. This enables two-stage telescopic design of the lamp holder, further expanding the adjustable range of the lamp holder's length and meeting the lighting layout needs of larger spaces (such as large exhibition halls and conference rooms). Simultaneously, the design logic of this two-stage telescopic structure is consistent with that of the first-stage telescopic structure, ensuring the overall structural coordination and stability. Of course, the lamp holder also has corresponding three-stage or higher telescopic structures.

[0023] Specifically, there is a gap between the outer wall of the second moving tube and the inner wall of the second sliding groove 22. A third sleeve 31 is provided at the end of the second moving tube inserted into the second sliding groove 22, which abuts against the inner wall of the second sliding groove 22. The third sleeve 31 abuts against the second limiting component 23 to prevent the second moving tube from falling off. The second limiting component 23 includes a fourth collar 231 fitted onto the protruding end of the first moving tube 2, and a second plastic ring 232 embedded within the fourth collar 231. The inner diameter of the second plastic ring 232 is smaller than the outer diameter of the second moving tube. Both the third sleeve 31 and the fourth collar 231 can be made of metal or plastic.

[0024] In the above embodiments, the shapes of the fixed tube 1, the first moving tube 2, and the second moving tube are one of the following: circular, square, rhomboid, and elliptical. Figure 7 In the third embodiment of this solution, the fixed tube 1, the first moving tube 2, and the second moving tube are square in shape, which can improve the adaptability of the product and increase its market competitiveness.

[0025] Reference Figures 8 to 10 This utility model also provides a lamp fixture using the lamp holder described above. The bottom of the fixed tube 1, the first moving tube 2, and the second moving tube are each provided with a first connector 4. A lamp holder 5 for lighting is detachably connected to the first connector 4 via a threaded connection. A second connector 6 is provided on the rear side of the fixed tube 1. A connecting rod 7 is detachably connected to the second connector 6 via a threaded connection. The other end of the connecting rod 7 is detachably connected to a base 8 for fixing to a wall via a threaded connection. Thus, when transporting this lamp fixture, the lamp holder, lamp holder 5, and base 8 can be separated and packaged separately, thereby avoiding increased shipping costs due to excessive packaging.

[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
