As shown in fig. 1 and 2, the utility model provides a rotation regulation structure, including cartridge head 10, button 20 and gear switch 30, the activity of button 20 sets up the one end at cartridge head 10, and gear switch 30 sets up in cartridge head 10. The automatic gear shifting device further comprises a rotating piece 40 and a rotating bracket 50 used for triggering the gear shifting switch 30, wherein the rotating piece 40 is rotatably sleeved on the cylinder head 10 and is in transmission connection with the button 20. The rotating bracket 50 is rotatably arranged in the cylinder head 10 and is in transmission connection with the button 20. The rotating member 40 is rotated by an external force, the button 20 is driven to rotate, and the rotating bracket 50 is driven to rotate, so that the rotating bracket 50 triggers the gear switch 30. The inhibitor switch 30 is a tact switch.

Since the rotating member 40 is in driving connection with the button 20, the rotating bracket 50 is in driving connection with the button 20; when the gear needs to be adjusted, the rotating part 40 can be rotated by external force, the button 20 is driven to rotate, and then the rotating bracket 50 is driven to rotate, so that the rotating bracket 50 triggers the gear switch 30, and the gear is adjusted once when the rotating bracket is triggered once, thereby realizing multi-stage adjustment. The rotary adjustment structure is ingenious, simple to operate and convenient to use. The range switch 30 has four ranges, and cyclically adjusts from the first range to the fourth range, i.e. the first range is increased by triggering once, and the first range is returned by triggering once after the fourth range.

In this embodiment, the rotation adjusting structure further includes a first elastic member 60 for providing a restoring force to the rotating bracket 50, and the first elastic member 60 is connected to the rotating bracket 50 and the inner wall of the cartridge head 10, respectively. When the rotating bracket 50 rotates a certain angle, the first elastic member 60 deforms to generate an elastic force; when the external force is removed, the rotating bracket 50 is reversely rotated by the elastic force of the first elastic member 60 to be restored to the original position.

As shown in fig. 3, the first elastic member 60 is a compression spring having two compression springs. The outer wall of the rotating bracket 50 is provided with a column 53 and a supporting plate 54, one end of the compression spring is sleeved on the column 53 during installation, and the other end of the compression spring is abutted against the inner wall of the barrel 10. Wherein the platform 54 primarily functions to lift the compression spring. When the compression spring is compressed, the radial limiting function can be achieved, and the compression spring is prevented from radially deforming and slipping.

The connecting rod 21 passes through the rotary member 40, the cylinder head 10 and the special-shaped hole 51 in sequence. When the button 20 is rotated, the link 21 drives the rotation bracket 50 to rotate. Therefore, the connecting rod 21 can only slide along the special-shaped hole 51, so that the button 20 can be pressed up and down movably, and the rotating bracket 50 can be driven to rotate. The special-shaped holes 51 are non-circular holes such as elongated holes, waist-shaped holes or cross-shaped holes.

In order to trigger the gearshift switch 30, the rotating bracket 50 is provided with a projection 52 for triggering the gearshift switch 30, and the projection 52 is rotated to the gearshift switch 30 by rotating the rotating bracket 50, so as to trigger the gearshift switch 30. Specifically, the rotating bracket 50 is opened with a limiting groove 55 for accommodating the shift switch 30, and the protrusion 52 is disposed at one side of the limiting groove 55. When the rotating bracket 50 rotates, the two side walls of the limiting groove 55 can play a limiting role, so that the rotating bracket 50 is limited to rotate within a certain angle.

As shown in fig. 5, the rotary member 40 is engaged with the button 20. The rotating member 40 is provided with a first latch 41, and the button 20 is provided with a first engaging groove 22 engaged with the first latch 41. This facilitates assembly and allows the button 20 to be rotated by rotating the rotary member 40.

In other embodiments, the first latch 41 may be disposed on the button 20, and the first latch 22 may be disposed on the rotating member 40, so that the rotating member 40 can be latched with the button 20.

Referring to fig. 5, the rotation adjusting structure further includes a positioning assembly 70 for positioning the rotating member 40, the inner wall of the rotating member 40 is provided with an adjusting groove 42 and a positioning groove 43, and the positioning assembly 70 is disposed on the cartridge head 10. The rotation of the rotary member 40 causes a portion of the positioning assembly 70 to be positioned in the adjustment groove 42 or the positioning groove 43. When the positioning assembly 70 is partially located in the adjustment slot 42, the overall structure is in an unlocked state, allowing for gear adjustment and illumination, and when the positioning assembly 70 is partially located in the positioning slot 43, the overall structure is in a locked state, and the button 20 cannot be pressed.

Specifically, the positioning assembly 70 includes a first protrusion 71 and a second elastic member 72, the inner wall of the rotating member 40 is provided with an adjusting groove 42 and a positioning groove 43, and the cartridge head 10 is provided with a first mounting hole 11. Referring to fig. 1, a second elastic member 72 is disposed in the first mounting hole 11 and coupled to the first protrusion 71. The first protrusion 71 is positioned in the adjustment groove 42 or the positioning groove 43 by rotating the rotary member 40. The first protruding member 71 is a sphere, preferably a steel ball, which has a smooth surface and a low friction force, and is convenient to switch between the adjusting groove 42 and the positioning groove 43. The second elastic member 72 is preferably a spring.

In this embodiment, the button 20 is provided with a second latch 26, and the barrel head 10 is provided with a second engaging slot 13 engaged with the second latch 26. When the first protrusion 71 is located in the adjustment groove 42, the second latch 26 is aligned with the second latch groove 13, and when the button 20 is pressed, the second latch 26 is inserted into the second latch groove 13. When the first protrusion 71 is located in the positioning groove 43, the second latch 26 is misaligned with the second latch groove 13, and the button 20 cannot be pressed.

As shown in fig. 5 and 6, the adjusting groove 42 is a groove with two ends having different depths, and one end of the adjusting groove 42 adjacent to the positioning groove 43 is lower, and in the unlocking state, the first protrusion 71 is located at the lower end of the adjusting groove 42. When the gear needs to be adjusted, the rotating member 40 can be pulled clockwise, so that the first convex member 71 moves towards the higher end, and the first convex member 71 retracts to compress the second elastic member 72. The structure can automatically move the first convex piece 71 to the lower end of the adjusting groove 42 when the external force is removed, and the design is ingenious. The positioning slot 43 is a semicircular slot, which is just matched with the first convex member 71, and when the external force is removed, the first convex member 71 will stay in the positioning slot 43.

In this embodiment, when the rotary member 40 rotates clockwise by 20 °, the first protrusion 71 moves from the lower end of the adjustment groove 42 into the positioning groove 43. When the rotating member 40 rotates 10 ° counterclockwise, the first protrusion 71 moves from the lower end of the adjustment groove 42 to the upper end of the adjustment groove 42, and the protrusion 52 rotates to the position switch 30 to trigger the position switch 30, thereby adjusting the gear.

As shown in fig. 7, the rotation adjusting structure further includes a circuit board 81, and the circuit board 81 is disposed below the rotating bracket 50 and provided with a conductive sheet 82 thereon. The button 20 is provided with a conductive shaft 23. The normally-on function is realized by pressing the button 20 to make the conductive shaft 23 electrically contact with the conductive sheet 82. Specifically, the conductive shaft 23 is inserted on the link 21.

Furthermore, the circuit board 81 is further provided with an elastic probe 83, and the conductive shaft 23 is provided with a flange 231. When the button 20 is pressed, the flange 231 of the conductive shaft 23 is brought into conductive contact with the elastic probe 83, thereby realizing the explosion function. The distance between the flange 231 and the resilient probe 83 is less than the distance between the conductive shaft 23 and the conductive sheet 82 so that the normally on function is not triggered when the burst function is used. Two of the elastic probes 83 are respectively disposed on two sides of the conductive sheet 82.

The elastic probes 83 are designed to have elasticity, and when the normally-on function is required, the elastic probes 83 are compressed, so that the conductive shaft 23 can be in conductive contact with the conductive sheet 82. Through software control, when the conductive shaft 23 is in conductive contact with the conductive sheet 82, only the normally-on function is executed, and the explosion flash is avoided.

Specifically, the rotation adjustment structure further includes a third elastic member 24 and a click assembly 90 for providing a restoring force to the button 20, and the third elastic member 24 abuts against the button 20 and the cartridge head 10, respectively. The third elastic member 24 is preferably a spring, and when the button 20 is pressed by an external force, the third elastic member 24 is compressed to generate an elastic restoring force, thereby facilitating the reset of the button 20.

Referring to fig. 7, the button 20 is provided with a slide slot 25, and the chucking assembly 90 is disposed on the cartridge head 10 and abuts against the slide slot 25. When the normally on function is activated by pressing the button 20, the clicking component 90 will generate a clicking feeling, thereby improving the hand feeling of use. Specifically, the slide groove 25 opens on the outer wall of the link 21.

In this embodiment, the chucking assembly 90 includes a second protrusion 91 and a fourth elastic member 92, the cartridge head 10 is provided with a second mounting hole 12, and the fourth elastic member 92 is disposed in the second mounting hole 12 and connected to the second protrusion 91 (refer to fig. 5). Wherein, the second convex member 91 is a pull bead, and the fourth elastic member 92 is a spring.

In the initial state, the second projection 91 abuts against the slide groove 25. When the button 20 is lightly pressed, the flange 231 of the conductive shaft 23 is in conductive contact with the elastic probe 83, and the flashing function is realized. The second projection 91 then abuts against the inside of the slide groove 25 and slides inside the slide groove 25. When the button 20 is pressed, the conductive shaft 23 is in conductive contact with the conductive sheet 82, and the normally-on function is realized. At this time, the second projection 91 jumps out of the slide groove 25, and a click feeling is generated.

The utility model also provides a flashlight, including the stack shell, be equipped with lighting module's lamp holder and as above rotation regulation structure, the lamp holder setting is in the one end of stack shell, and cartridge head 10 sets up the other end at the stack shell.
