[0024] FIG1 is a schematic diagram of the structure of the lens locking mechanism provided in this embodiment, FIG2 is a schematic diagram of the structure of the slider 1, switch 2, and locking member 3 provided in this embodiment, FIG3 is a schematic diagram of the structure of the slider 1 and locking member 3 provided in this embodiment, and FIG4 is a schematic diagram of the structure of the base 4 provided in this embodiment. As shown in FIG1-4, the lens locking mechanism is used to adjust the position of the lens 100. The lens locking mechanism includes a slider 1, a switch 2, and a locking member 3. The slider 1 includes a first clamping portion 11; the switch 2 is arranged to move relative to the slider 1, and the switch 2 includes a second clamping portion 21. The first clamping portion 11 and the second clamping portion 21 cooperate with each other to have a locked state and an unlocked state. In the locked state, the first clamping portion 11 and the second clamping portion 21 can prevent the lens 100 from disengaging from the lens locking mechanism. In the unlocked state, the first clamping portion 11 and the second clamping portion 21 can also release the restriction between the lens 100 and the lens locking mechanism; the locking member 3 can fix the relative position of the switch 2 and the slider 1.

[0025] By cooperating with the first clamping portion 11 of the slider 1 and the second clamping portion 21 of the switch 2, the lens 100 can be restricted from disengaging from the lens locking mechanism, and the restriction between the lens 100 and the lens locking mechanism can be released, so that the lens 100 can be conveniently removed, and the installation and replacement of the lens 100 is facilitated; by relatively movable arrangement of the switch 2 and the slider 1, the switch 2 drives the second clamping portion 21 to move relative to the first clamping portion 11 of the slider 1, thereby realizing the mutual cooperation between the first clamping portion 11 and the second clamping portion 21; by providing the locking member 3, the relative position of the switch 2 and the slider 1 is fixed, thereby restricting the lens 100 from disengaging from the lens locking mechanism and improving the stability of the fixation between the lens 100 and the lens locking mechanism.

[0026] In some embodiments, one end of the locking member 3 is rotatably connected to the slider 1, and the other end can abut the switch 2 to fix the relative position of the switch 2 and the slider 1, thereby fixing the relative position of the switch 2 and the slider 1, and through the sliding connection, the locking member 3 can also release the fixation of the switch 2 and the slider 1, so that the first clamping portion 11 and the second clamping portion 21 can be more stable in the locked state, and can still achieve the unlocked state.

[0027] Optionally, a receiving groove 12 is provided on the slider 1, and the receiving groove 12 is used to accommodate the locking member 3. Through the setting of the receiving groove 12, the locking member 3 will not affect the normal use of the switch 2 when it is not abutting the switch 2, and provide space for the relative movement of the switch 2 and the slider 1.

[0028] Optionally, one of the accommodating groove 12 and the locking member 3 is provided with a first pin shaft, and the other is provided with a first connecting hole that cooperates with the first pin shaft. The first connecting hole is sleeved on the first pin shaft, and the locking member 3 rotates around the first pin shaft through the first connecting hole, thereby realizing the rotational connection between the locking member 3 and the slider 1.

[0029] In this embodiment, the first pin is provided on the wall of the accommodating groove 12, and the first connecting hole is provided on the locking member 3. In other embodiments, the first pin can also be provided on the locking member 3, and the first connecting hole can also be provided on the wall of the accommodating groove 12.

[0030] Figure 5 shows a schematic structural diagram of the base 4 provided in this embodiment. As shown in Figure 5 and in conjunction with Figures 1-4 , the lens locking mechanism further comprises a base 4 having a receiving cavity 41 defined therein. The slider 1, switch 2, and locking member 3 are all disposed within the receiving cavity 41, thereby making the internal structure of the lens locking mechanism more compact.

[0031] Figure 6 shows a schematic structural diagram of the slider 1, switch 2, and locking member 3 provided by this embodiment from another perspective. As shown in Figure 6 and in conjunction with Figures 1-4, one of the switch 2 and slider 1 is provided with a second pin 22, and the other is provided with a second connecting hole 13 that mates with the second pin 22. The second connecting hole 13 is sleeved onto the second pin 22, and the slider 1 rotates around the second pin 22 through the second connecting hole 13, thereby achieving relative movement between the slider 1 and the switch 2, and enabling the first engaging portion 11 and the second engaging portion 21 to be locked and unlocked.

[0032] In this embodiment, the second pin 22 is provided on the switch 2, and the second connection hole 13 is provided on the slider 1. In other embodiments, the second pin 22 can also be provided on the slider 1, and the second connection hole 13 can also be provided on the switch 2.

[0033] Figure 7 is a schematic diagram of the structure of the goggles provided in this embodiment, Figure 8 is a schematic diagram of the structure of the lens 100 provided in this embodiment, and Figure 9 is a schematic diagram of the structure of the lens 100, slider 1, switch 2, and locking member 3 provided in this embodiment. As shown in Figures 7-9 in conjunction with Figures 1-6, this embodiment further provides goggles, which include a lens locking mechanism and a lens 100. The lens 100 is provided with a clamping post 101. The first clamping portion 11 and the second clamping portion 21 cooperate and can be clamped to the clamping post 101 to prevent the lens 100 from disengaging from the lens locking mechanism. When in the locked state, the clamping post 101 on the lens 100 extends into between the first clamping portion 11 and the second clamping portion 21 of the lens locking mechanism, and the push switch 2 drives the second clamping portion 21 and the first clamping portion 11 of the slider 1 to approach each other to abutment state, and the first clamping portion 11 and the second clamping portion 21 cooperate together and clamp with the clamping post 101 to limit the separation between the lens 100 and the lens locking mechanism; when in the unlocked state, the push switch 2 drives the second clamping portion 21 and the first clamping portion 11 of the slider 1 to move away from each other and no longer abut, and the first clamping portion 11 and the second clamping portion 21 no longer cooperate together to clamp with the clamping post 101, and the clamping post 101 pops out from between the first clamping portion 11 and the second clamping portion 21 to release the restriction between the lens 100 and the lens locking mechanism.

[0034] In some embodiments, the switch 2 further includes a pop-up portion 23 , which can push out the clamping post 101 in the unlocked state, thereby allowing the clamping post 101 to pop out quickly.

[0035] Optionally, the pop-up portion 23 can abut against the lens 100, and the side of the pop-up portion 23 abutting against the lens 100 is set as a slope to separate the lens 100 from the lens locking mechanism when in the unlocked state. Through the setting of the slope, it is possible to abut against the clamping column 101 and quickly pop out the clamping column 101. It is also possible to drive the pop-up portion 23 through the relative movement of the switch 2 and the slide when the clamping column 101 extends between the first clamping portion 11 and the second clamping portion 21 of the lens locking mechanism, thereby providing space for the clamping column 101.

[0036] Optionally, a blocking portion 1011 is provided on the clamping column 101, and the first clamping portion 11 and the second clamping portion 21 cooperate with each other and are clamped to the clamping column 101 through the blocking portion 1011. The setting of the blocking portion 1011 enables the first clamping portion 11 and the second clamping portion 21 to cooperate with each other and be clamped to the clamping column 101.

[0037] In some embodiments, a guide rail 42 is further provided on the base 4. The guide rail 42 is a curved shape extending along the edge of the base 4. A limiting column 102 is also provided on the lens 100. The guide rail 42 is used to provide guidance for the limiting column 102 when it moves, and can limit the limiting column 102 during movement.

[0038] Optionally, the blocking portion 1011 is an arc protrusion arranged along the circumference of the clamping column 101. By setting the blocking portion 1011 as an arc protrusion, it can not only cooperate with the movement of the limiting column 102, but also prevent the limiting column 102 from being stuck between the pop-up portion 23 and the blocking portion 1011 when moving, causing the limiting column 102 to be unable to move.
