DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features, and effects according to the present utility model as follows.

[0023] Embodiment 1:

[0024] A handle telescopic mechanism provided in this embodiment is as shown in Figure 1 、 Figure 2 and includes a lamp body 1, a limiting member 2, a handle 3, and a fastener 4. An installation plate 5 is provided on the lamp body 1. The limiting member 2 is connected to the installation plate 5. A through guiding groove 6 is provided on the limiting member 2. The handle 3 is slidably inserted into the guiding groove 6; the fastener 4 is connected to the lamp body 1 and is used to lock or unlock the handle 3; the bottom of the installation plate 5 is fixedly connected to the lamp body 1. The free rotation of the handle 3 is restricted by the limiting member 2, facilitating the telescopic adjustment of the handle 3; the handle 3 cooperates with the guiding groove 6, and the guiding groove 6 can provide guidance for the telescopic movement of the handle 3. The handle 3 cannot rotate freely, making the telescopic adjustment of the handle 3 more convenient.

[0025] For reliable guiding, the installation plate 5 is provided on both sides of the lamp body 1; the handle 3 is U-shaped, and the two side edges of the handle 3 are respectively inserted into the guiding grooves 6 on both sides. The installation plate 5 is provided on both sides, so that the limiting members 2 are provided on both sides. Both sides of the U-shaped handle 3 can be guided, and the telescopic movement of the handle 3 is smoother; the U-shaped handle 3 is more suitable for holding and using; the U-shaped design facilitates the forming of the plate member by bending, with a simple process and reduced production costs.

[0026] For the reliable limiting member 2, as shown in Figure 4 , the limiting member 2 includes a guiding block 7 and an installation block 8. The guiding groove 6 is provided on the guiding block 7. An installation groove 9 is provided on the installation block 8, and the installation groove 9 is sleeved on the installation plate 5; the opening direction of the installation groove 9 is perpendicular to the opening direction of the guiding groove 6. The guiding groove 6 and the installation groove 9 are respectively arranged on the guiding block 7 and the installation block 8, with less interference; the installation groove 9 is sleeved on the installation plate 5, making the disassembly and assembly of the two convenient, improving the assembly efficiency, and facilitating later replacement and maintenance; the opening direction of the installation groove 9 is perpendicular to the opening direction of the guiding groove 6, so that the friction force when the handle 3 moves in the guiding groove 6 will not cause the movement of the installation groove 9 relative to the installation plate 5.

[0027] For the reliable fixation of the limiting member 2, as shown in Figure 3As shown, threaded holes 10 are provided on the mounting plate 5, and through holes 11 are provided on the limiting member 2. The threaded holes 10 and the through holes 11 are concentric. The fastener 4 includes a screw rod 12 and a knob 13. The screw rod 12 passes through the through hole 11 and is connected to the threaded hole 10. The bottom of the knob 13 abuts against the guide block 7. The cooperation between the threaded hole 10 and the screw rod 12 enables the knob 13 to be adjusted up and down. Further, the knob 13 can press the guide block 7, increasing the friction between the guide groove 6 and the handle 3, so that the handle 3 is fixed. The screw rod 12 passes through the through hole 11, playing a role in limiting the limiting member 2 and preventing the limiting member 2 from coming off.

[0028] To ensure reliable use of the handle 3, a sliding hole 14 is provided on the handle 3, and the screw rod 12 is inserted into the sliding hole 14. A first notch 15 is formed on one side of the guide block 7 facing the knob 13. The first notch 15 communicates with the sliding hole 14, and the screw rod 12 is inserted into the first notch 15. The bottom of the knob 13 abuts against the edge of the first notch 15. The sliding hole 14 is an oblong hole, which can limit the telescopic range of the handle 3. The design of the sliding hole 14 enables the handle 3 to also be telescopically movable after the screw rod 12 passes through the handle 3. The design of the first notch 15 reduces the structural strength of the side of the guide block 7 facing the knob 13, facilitating the pressing of the knob 13.

[0029] To make the pressing of the knob 13 more reliable, the limiting member 2 is made of plastic. The plastic limiting member 2 is easier to press, the knob 13 is more labor-saving when pressing, and at the same time, the production cost can be reduced.

[0030] To ensure reliable fixation of the mounting plate 5, as Figure 5 shown, a connecting plate 16 is provided on the mounting plate 5. The two ends of the connecting plate 16 are respectively connected to the mounting plate 5 and the lamp body 1. A second notch 17 is formed on one side of the mounting block 8 facing the lamp body 1. The second notch 17 communicates with the mounting groove 9, and the connecting plate 16 is inserted into the second notch 17. The mounting plate 5 is connected to the lamp body 1 through the connecting plate 16, improving the connection strength between the mounting plate 5 and the lamp body 1. The design of the second notch 17 facilitates the mounting block 8 to be sleeved onto the mounting plate 5. At the same time, the second notch 17 cooperates with the connecting plate 16 to play a role in limiting the mounting block 8.

[0031] To improve the connection strength of the mounting plate 5, the connecting plates 16 are provided on both sides of the mounting plate 5. The connecting plates 16 are provided on both sides, which can improve the connection strength between the mounting plate 5 and the lamp body 1.

[0032] To improve the structural strength of the limiting member 2, a reinforcing plate 18 is provided between the guide block 7 and the mounting block 8. The design of the reinforcing plate 18 makes the connection strength between the guide block 7 and the mounting block 8 high, reducing the influence of the opening of the second notch 17 on the structural strength of the mounting block 8.

[0033] During use, rotate the knob 13 so that the bottom of the knob 13 no longer abuts against the guide block 7. At this time, the fastener 4 unlocks the handle 3, and the handle 3 can move freely along the direction of the guide groove 6 for telescoping. After the handle 3 is telescoped, tighten the knob 13. The bottom of the knob 13 abuts against and presses the guide block 7, so that the groove wall of the guide groove 6 fits and presses against the handle 3, and the handle 3 cannot move and is in a locked state.

[0034] The handle telescoping mechanism can be used for a series of lamps such as floodlights, rechargeable lamps, AC working bracket lamps, solar lamps, RGB lamps, etc.

[0035] Embodiment 2:

[0036] A lamp provided in this embodiment includes a handle telescoping mechanism described in Embodiment 1.
