[0045] The lamp tube 1 is provided with a guide hole 12 extending along the axial direction, and the sliding sleeve 5 is provided with a tapered connecting hole 51 with internal threads.

[0046] The handle 7 includes a button 71 and a connecting rod 72 connected to the button 71. The end of the connecting rod 72 is provided with a tapered connecting end 721 with external threads.

[0047] Button 71 is positioned outside guide hole 12, and the diameter of button 71 is larger than the width of guide hole 12. Connecting rod 72 passes through guide hole 12 with a gap, and tapered connecting end 721 is threaded into tapered connecting hole 51.

[0048] The lamp provided by this utility model includes a lamp tube 1, a heat sink 2, a light source 3, a sliding sleeve 5, a lens 6, and a handle 7, etc.

[0049] The front end of the lamp tube 1 is the light-emitting end, the heat sink 2 is installed at the rear end of the lamp tube 1, and the light source 3 is installed at the front end of the heat sink 2. The lamp tube 1 can be fixed by screws 14. If necessary, a boom 4 can be configured at the rear end of the heat sink 2. The boom 4 is hinged to the heat sink 2. A clearance groove 11 is provided at the rear end of the lamp tube 1. When the lamp tube 1 is swung so that it is tilted or perpendicular to the boom 4, the boom 4 enters the clearance groove 11.

[0050] The sliding sleeve 5 is assembled in the lamp tube 1, located in front of the heat sink 2, and can slide axially within the lamp tube 1. The lens 6 is assembled in the sliding sleeve 5, preferably a convex lens. By moving the sliding sleeve 5 back and forth, the distance between the light source 3 and the lens 6 can be adjusted, thereby achieving focusing or adjusting the light pattern.

[0051] The lamp tube 1 has an elongated guide hole 12 on its wall, which extends along the axial direction (front-back direction) of the lamp tube 1. The sliding sleeve 5 has a tapered connecting hole 51 on its wall, and its inner surface is threaded.

[0052] The handle 7 includes a button 71 and a connecting rod 72, with the connecting rod 72 connected to one side of the button 71. Preferably, the connecting rod 72 is integrally formed with the button 71. The button 71 is disc-shaped, and its diameter is larger than the width of the guide hole 12, preventing it from falling out of the guide hole 12. The diameter of the connecting rod 72 is smaller than the width of the guide hole 12, allowing it to slide along the guide hole 12. The end of the connecting rod 72 is a tapered connecting end 721, which is adapted to a tapered connecting hole 51, and the surface of the tapered connecting end 721 is provided with external threads.

[0053] During assembly, the sliding sleeve 5 is installed in the lamp holder 1, with the tapered connecting hole 51 protruding from the guide hole 12. Then, the connecting rod 72 is passed through the guide hole 12, and the tapered connecting end 721 is connected to the tapered connecting hole 51. As long as the tapered connecting end 721 can be inserted into the tapered connecting hole 51, it can automatically achieve alignment with the tapered connecting hole 51, facilitating assembly. The button 71 is large and fully exposed outside the guide hole 12, allowing users to easily operate the button 71 and greatly improving the user experience.

[0054] In one embodiment, such as Figure 1 , Figure 4 and Figure 6 As shown, the surface of button 71 is provided with a finger receiving groove 711 for placing the user's finger. The user can place the end of the thumb or index finger in the finger receiving groove 711. The flange portion of the finger receiving groove 711 acts as a blocking function so that the user can apply force to operate the handle 7, thereby pushing and pulling the sliding sleeve 5.

[0055] In one embodiment, a guide structure for guiding the linear movement of the sliding sleeve 5 is assembled between the sliding sleeve 5 and the lamp tube 1.

[0056] The guide structure can adopt a linear guide structure such as a guide rail or a slide groove to guide the sliding sleeve 5 to slide along a straight line. It also restricts the rotation of the sliding sleeve 5 to prevent the sliding sleeve 5 from rotating during assembly, which would prevent the tapered connecting hole 51 from being exposed from the guide hole 12.

[0057] In one embodiment, such as Figures 2-3 and Figure 5As shown, the guide structure includes a guide groove 13 provided on the inner surface of the lamp holder 1 and extending axially, and a guide protrusion 52 provided on the outer peripheral surface of the sliding sleeve 5. The guide protrusion 52 is clearance-fitted into the guide groove 13.

[0058] In this embodiment, the guiding structure adopts a combination of guide groove 13 and guide protrusion 52. Guide groove 13 is provided on the inner surface of lamp tube 1 and extends along the axial direction, and guide protrusion 52 is provided on the outer peripheral surface of sliding sleeve 5. When sliding sleeve 5 is installed into lamp tube 1, guide protrusion 52 is aligned with guide groove 13 and installed, so that sliding sleeve 5 can only move axially and will not rotate.

[0059] Preferably, the guide protrusion 52 and the sliding sleeve 5 are integrally formed.

[0060] The guide protrusion 52 can extend along the axial direction of the sliding sleeve 5, and the guide protrusion 52 is flush with both ends of the sliding sleeve 5.

[0061] The guide protrusion 52 can also be located only at the rear end of the sliding sleeve 5. The guide protrusion 52 will not disengage from the guide groove 13 before the rear end of the sliding sleeve 5 disengages from the lamp tube 1. Compared with the aforementioned method, the guide protrusion 52 in this method is shorter, which helps to reduce the structural weight. When the sliding sleeve 5 is extended, the user cannot see the guide protrusion 52.

[0062] In one embodiment, such as Figures 2-3 and Figure 5 As shown, the inner surface of the lamp holder 1 is provided with two opposing guide grooves 13, and correspondingly, the outer peripheral surface of the sliding sleeve 5 is provided with two opposing guide protrusions 52. Each guide protrusion 52 is fitted into one guide groove 13 with clearance.

[0063] By using a pair of guide grooves 13 and a pair of guide protrusions 52 in combination, the stability of the sliding guide sleeve 5 can be further improved.

[0064] In one embodiment, such as Figure 5 and Figures 8-9 As shown, the sliding sleeve 5 is provided with a first claw 53, and the lens 6 is fixed in the sliding sleeve 5 by the first claw 53 so that the lens 6 can be assembled in the sliding sleeve 5.

[0065] The first claw 53 is an elastic claw used to clamp the edge 61 of the lens 6. The first claw 53 can be annular, with an L-shaped or transverse U-shaped cross-section. Only one first claw 53 needs to be provided in the sliding sleeve 5.

[0066] The first claw 53 can also be a strip-shaped or block-shaped L-shaped claw. As needed, multiple first claws 53 can be arranged at intervals along the circumferential direction in the sliding sleeve 5 to improve the stability of the lens 6 installation.

[0067] In one embodiment, such as Figures 1-2 , Figures 8-9 and Figure 11 As shown, the end of the sliding sleeve 5 is connected to the light guide sleeve 8.

[0068] When the connecting rod 72 is at the rear end of the guide hole 12, the light guide sleeve 8 is housed in the lamp tube 1.

[0069] When the connecting rod 72 is at the front end of the guide hole 12, the light guide sleeve 8 extends out of the outside of the lamp tube 1.

[0070] In this embodiment, a light guide sleeve 8 is configured at the front end of the sliding sleeve 5 to increase the light guide length. When the user operates the button 71 and the connecting rod 72 is at the rear end of the guide hole 12, the light guide sleeve 8 is housed in the lamp tube 1. When the user operates the handle 71 and the connecting rod 72 is at the front end of the guide hole 12, the light guide sleeve 8 extends out of the outside of the lamp tube 1 to extend the light guide path and make the light shine out in the specified direction as much as possible.

[0071] In one embodiment, such as Figures 7-9 As shown, one end of the light guide sleeve 8 extends into the sliding sleeve 5, and the sliding sleeve 5 and the light guide sleeve 8 are connected by a locking pin 55.

[0072] In this embodiment, a plurality of locking pins 55 are provided on the side of the sliding sleeve 5 to fix the light guide sleeve 8 to the sliding sleeve 5.

Several mounting holes are provided at the front end of the sliding sleeve 5. A locking pin 55 is installed in the mounting holes and extends into the groove 81 to fix the sliding sleeve 5. The front end of the lamp tube 1 covers the through hole, thus preventing the locking pin 55 from disengaging from the mounting hole and also preventing the user from seeing the locking pin 55. The locking pin 55 can be threaded into the mounting hole.

[0074] In one embodiment, such as Figures 10-12 As shown, the light guide sleeve 8 and the sliding sleeve 5 are connected by the adapter structure 9.

[0075] The adapter structure 9 includes an adapter ring 91 and a plurality of second claws 92 disposed on the front end face of the adapter ring 91, and the rear end face of the adapter ring 91 is provided with an adapter ring flange 93.

[0076] The second claw 92 extends into the light guide sleeve 8 and engages with it. The flange 93 of the adapter ring engages with the first claw 53. The edge 61 of the lens 6 presses against the flange 93 of the adapter ring.

[0077] In this embodiment, a transition structure 9 is used to connect the light guide sleeve 8 and the sliding sleeve 5 together, and then assemble them together with the lens 6.

[0078] The adapter structure 9 includes an adapter ring 91, with a plurality of second claws 92 spaced apart on the front end face of the adapter ring 91, and a radially outwardly extending adapter ring flange 93 on the rear end face of the adapter ring 91.

[0079] The inner surface of the light guide sleeve 8 is provided with an annular groove 82. The second claw 92 extends into the light guide sleeve 8 and is engaged in the annular groove 82. The flange 93 of the adapter ring is engaged with the first claw 53. The edge 61 of the lens 6 is pressed on the flange 93 of the adapter ring, so that the sliding sleeve 5, the light guide sleeve 8, the adapter structure 9 and the lens 6 are combined together, which improves the structural stability.

[0080] Preferably, the second claw 92, the adapter ring flange 93, and the adapter ring 91 are integrally formed.

[0081] In one embodiment, such as Figure 5 and Figures 11-12 As shown, the sliding sleeve 5 has an intermediate ring 54, the first pawl 53 is located on the front side of the intermediate ring 54, and the edge 61 of the lens 6 is fastened between the inner edge of the intermediate ring 54 and the flange 93 of the adapter ring.

[0082] In this embodiment, to facilitate the installation of the first claw 53 and improve the installation stability of the lens 6, an intermediate ring 54 is provided inside the sliding sleeve 5, and multiple first claws 53 are disposed on the front surface of the sliding sleeve 5. The first claws 53 are L-shaped. The first claws 53 are a certain distance away from the inner edge of the intermediate ring 54, so that the inner edge of the intermediate ring 54 can press against the edge 61 of the lens 6. A clamping groove is formed between the L-shaped front end of the first claw 53 and the inner edge of the intermediate ring 54. The edge 61 of the lens 6 and the flange 93 of the adapter ring are squeezed tightly in the clamping groove, and the edge 61 of the lens 6 is fixed between the inner edge of the intermediate ring 54 and the flange 93 of the adapter ring, which improves the installation stability of the lens 6 and prevents the lens 6 from shaking.

[0083] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0084] The above are merely the principles and preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of this utility model, and these modifications should also be considered within the scope of protection of this utility model.
