[0034] In this embodiment of the present application, Figure 1 - Figure 8 As shown, an adjustable focusing LED lamp is provided, comprising a cylindrical shell 1, and further comprising: a front control rotating circle 3 arranged at the front end of the cylindrical shell 1 and a rear control rotating circle 2 arranged at the rear end of the cylindrical shell 1, wherein the front control rotating circle 3 and the rear control rotating circle 2 are both used to control the sliding of a lens 5;

[0035] The lens 5 is installed and connected to the adjustable cylinder 7, and the outer cover of the adjustable cylinder 7 is provided with a front control circle 3, and the front control circle 3 is connected to the rear control circle 2 by a synchronization rod 12; the operator can operate the rear control circle 2 to rotate by a positive grip to achieve focusing adjustment of the position of the lens 5, or operate the front control circle 3 to rotate by a reverse grip to achieve focusing adjustment of the position of the lens 5. Compared with the traditional focusing adjustment structure, it is more convenient and applicable to more usage scenarios.

[0036] The outer wall of the adjustable cylinder 7 is provided with a spiral groove, and the inner wall of the front control circle 3 is provided with a spiral protrusion, and the structure of the spiral protrusion is adapted to the structure of the spiral groove; the front control circle 3 is rotatably connected to the cylindrical shell 1, and the operator can push the adjustable cylinder 7 to slide and move by controlling the rotation of the front control circle 3 and the rear control circle 2, thereby realizing the adjustment of the position of the lens 5. Through this adjustment method, the position of the lens 5 can remain stable at any time after adjustment.

[0037] One end of the adjustable cylinder 7 is slidably connected to the inner cylinder 9, and the inner cylinder 9 is fixedly connected to the cylindrical shell 1; through the restriction of the adjustable cylinder 7 by the inner cylinder 9, the adjustable cylinder 7 can slide stably in a straight line without rotational movement.

[0038] A rear cover 8 is provided at the rear end of the inner cylinder 9. A switch is provided on the rear cover 8. Opening the rear cover 8 facilitates installation and removal of batteries.

[0039] Several sliding supports extend from one end of the adjustable cylinder 7 close to the inner cylinder 9, and a slide groove adapted to the sliding support is provided at one end of the inner cylinder 9 close to the adjustable cylinder 7; the slide groove slides with the sliding support, and the slide groove can limit the sliding support so that the sliding support maintains stable linear sliding.

[0040] The inner wall of the adjustable tube 7 is surrounded by a plurality of through grooves; a lampshade 4 is provided at the front end of the adjustable tube 7, and a plurality of limit strips 6 are provided at one end of the lampshade 4, and the limit strips 6 pass through the through grooves and are clamped and fixed to the inner tube 9; the limit strips 6 slide in cooperation with the through grooves, and the setting of the limit strips 6 can further improve the sliding stability of the adjustable tube 7, and the limit strips 6 are connected to the lampshade 4, and the lampshade 4 can also play an auxiliary heat dissipation role.

[0041] Two grooves are symmetrically arranged on the inner wall of the cylindrical shell 1, and an elastic connecting block 10 is slidably arranged in the groove. One end of the elastic connecting block 10 protrudes from the groove and is connected to the outer wall of the inner cylinder 9. The other end of the elastic connecting block 10 is connected to the inner wall of the groove through an elastic supporting member 11, and the elastic supporting member 11 is a metal spring sheet; the metal spring sheet can provide elastic support for the elastic supporting member 11; the elastic connecting block 10 is in contact with the outer wall of the inner cylinder 9, so that the inner cylinder 9 and the cylindrical shell 1 can remain relatively fixed without relative rotation.

[0042] Guide slopes are provided on both sides of the elastic connection block 10; the position of the synchronization rod 12 corresponds to the position of the guide slopes; when the synchronization rod 12 rotates to the position of the elastic connection block 10 along with the front control circle 3 and the rear control circle 2, the guide slopes can be squeezed to retract the elastic connection block 10 into the groove of the cylindrical shell 1, thereby not hindering the rotation of the front control circle 3 and the rear control circle 2, so that the front control circle 3 and the rear control circle 2 can rotate more than 360°.

[0043] There are multiple synchronization rods 12, and the multiple synchronization rods 12 are asymmetrically arranged relative to the center of the front control circle 3 and the rear control circle 2; because the grooves on the cylindrical shell 1 are relatively arranged, the asymmetrically arranged synchronization rods 12 can always only squeeze and push away one elastic connecting block 10, and at least keep one elastic connecting block 10 in contact with the inner cylinder 9, so that the inner cylinder 9 and the cylindrical shell 1 remain relatively fixed.

[0044] One end face of the elastic connection block 10 protruding from the groove is provided with a convex tooth structure, and the outer wall of the inner tube 9 is provided with a slot structure adapted to the convex tooth structure; the coordination of the convex tooth structure and the slot structure allows the elastic connection block 10 to be more stably connected to the inner tube 9.
