[0027] The embodiments of this application will be further described below with reference to the accompanying drawings.
[0028] An embodiment of this application provides a snap-on lens cap.
[0029] Reference Figure 1 , Figure 2 and Figure 3 A snap-on lens cap, comprising: a cap body 100, a pressing element 200, and a snap-on element 300.
[0030] The cover 100 is provided with a mounting groove 110; the pressing member 200 is disposed in the mounting groove 110; the fastening member 300 is disposed in the mounting groove 110 and is connected to the pressing member 200; when the pressing member 200 moves inward toward the cover 100, the pressing member 200 pushes the fastening member 300 to move outward toward the cover 100; when the pressing member 200 moves outward toward the cover 100, the fastening member 300 moves inward toward the cover 100.
[0031] In this embodiment, when it is necessary to fasten the snap-on lens cap onto the lens 10, the pressing member 200 is pressed down, causing the pressing member 200 to move inward toward the cover body 100. The pressing member 200 pushes the snap-on member 300 to move outward toward the cover body 100, thus expanding the mounting diameter of the snap-on lens cap. At this time, the snap-on lens cap can be placed on the lens 10, and the snap-on member 300 is positioned outside the latch 11 of the lens 10. When the pressing member 200 moves outward toward the cover body 100 and the snap-on member 300 moves inward toward the cover body 100, the snap-on member 300 moves toward the latch 11 of the lens 10, thus reducing the mounting diameter of the snap-on lens cap until the snap-on member 300 is engaged with the latch 11 of the lens 10.
[0032] When it is necessary to remove the snap-on lens 10 from the lens 10, press down the pressing member 200, causing the pressing member 200 to move inward toward the cover 100. The pressing member 200 pushes the snap-on member 300 to move outward toward the cover 100, and the snap-on member 300 moves away from the latch 11 of the lens 10. The mounting diameter of the snap-on lens cover expands. When the mounting diameter of the snap-on lens cover is larger than the latch 11 of the lens 10, the snap-on member 300 disengages from the latch 11, and the snap-on lens 10 can be removed from the lens 10.
[0033] This ensures the lens cap is securely fastened to the bayonet 11 of the lens 10, preventing it from falling off. By driving the latching component 300 to move, the mounting diameter of the snap-on lens cap is adjusted, allowing it to accommodate various lenses 10 with different outer diameters, thus improving its versatility.
[0034] The lens cap can be easily removed and installed by simply pressing the presser 200, which improves convenience.
[0035] The outer wall 120 of the mounting groove 110 is provided with an opening 140, and the pressing member 200 is provided with a protruding pressing part 210, which extends out from the opening 140.
[0036] It can be understood that the cover 100 is circular, with the inner direction of the cover 100 being from the edge of the circle to the center, and the outer direction of the cover 100 being from the center to the edge of the circle.
[0037] Reference Figure 2 There are two openings 140 on the outer wall 120 of the mounting groove 110, and there are also two pressing parts 200. The two openings 140 are arranged opposite each other, and the two pressing parts 200 are arranged opposite each other. This makes it convenient for the user to press the two pressing parts 200 with their thumb and forefinger respectively.
[0038] Reference Figure 3 The surface of the pressing part 210 is provided with teeth, which increases the coefficient of friction of the pressing part 210, making it easier for the user to grip the pressing part 210.
[0039] A first elastic element 410 is provided between the pressing member 200 and the inner groove wall 130 of the mounting groove 110. The first elastic element 410 is used to move the pressing member 200 to the outside of the cover 100. Specifically, the first elastic element 410 is a spring.
[0040] When the snap-on lens cap needs to be fastened onto the lens 10, the pressing member 200 is pressed down, causing it to move inward toward the cover body 100. The pressing member 200 compresses the first elastic member 410, causing it to contract. The pressing member 200 pushes the snap-on member 300 outward toward the cover body 100, expanding the mounting diameter of the snap-on lens cap. At this point, the snap-on lens cap can be placed on the lens 10, with the snap-on member 300 positioned outside the latch 11 of the lens 10. When the pressing member 200 is no longer pressed down, the contracted first elastic member 410 returns to its original position, causing the pressing member 200 to move outward toward the cover body 100 and the snap-on member 300 to move inward toward the cover body 100. The snap-on member 300 then moves toward the latch 11 of the lens 10, reducing the mounting diameter of the snap-on lens cap until the snap-on member 300 is locked onto the latch 11 of the lens 10.
[0041] When it is necessary to remove the snap-on lens 10 from the lens 10, the pressing member 200 is pressed down, causing it to move inward toward the cover 100. This causes the first elastic member 410 to contract, and the pressing member 200 pushes the snap-on member 300 outward toward the cover 100. The snap-on member 300 then moves away from the latch 11 of the lens 10, widening the mounting diameter of the snap-on lens cap. When the mounting diameter of the snap-on lens cap is larger than the latch 11 of the lens 10, the snap-on member 300 disengages from the latch 11, allowing the snap-on lens 10 to be removed from the lens 10. When the pressing member 200 is no longer pressed down, the contracted first elastic member 410 returns to its original position, causing the pressing member 200 to move outward toward the cover 100 and the snap-on member 300 to move inward toward the cover 100.
[0042] Reference Figure 2 The pressing member 200 has a first receiving groove 510 on the side near the inner groove wall 130, and one end of the first elastic member 410 is placed in the first receiving groove 510. The first receiving groove 510 positions the first elastic member 410 to prevent the first elastic member 410 from shifting position.
[0043] A second elastic element 420 is provided between the fastener 300 and the outer groove wall 120 of the mounting groove 110. The second elastic element 420 is used to move the fastener 300 toward the inside of the cover 100. Specifically, the second elastic element 420 is a spring.
[0044] When the snap-on lens cap needs to be fastened onto the lens 10, the pressing member 200 is pressed down, causing it to move inward toward the inside of the cap body 100. The pressing member 200 compresses the first elastic member 410, causing it to contract. The pressing member 200 also pushes the snap-on member 300 outward toward the outside of the cap body 100, causing the second elastic member 420 to contract. This expands the mounting opening of the snap-on lens cap, allowing it to be fastened onto the lens 10. The component 300 is placed on the outside of the bayonet 11 of the lens 10; when the pressing component 200 is no longer pressed, the first elastic component 410 recovers, causing the pressing component 200 to move outward towards the cover 100, and the second elastic component 420 recovers, causing the latching component 300 to move inward towards the cover 100. Then the latching component 300 moves towards the bayonet 11 of the lens 10, and the mounting diameter of the latching lens cap is reduced until the latching component 300 is locked onto the bayonet 11 of the lens 10.
[0045] When it is necessary to remove the snap-on lens 10 from the lens 10, the pressing member 200 is pressed down, causing it to move inward toward the cover 100. This causes the first elastic member 410 to contract, and the pressing member 200 pushes the snap-on member 300 outward toward the cover 100, causing the second elastic member 420 to contract. The snap-on member 300 then moves away from the latch 11 of the lens 10, widening the mounting diameter of the snap-on lens cap. When the mounting diameter of the snap-on lens cap is larger than the latch 11 of the lens 10, the snap-on member 300 disengages from the latch 11, allowing the snap-on lens 10 to be removed from the lens 10. When the pressing member 200 is no longer pressed down, the contracted first elastic member 410 returns to its original position, causing the pressing member 200 to move outward toward the cover 100. The contracted second elastic member 420 returns to its original position, causing the snap-on member 300 to move inward toward the cover 100.
[0046] The fastener 300 has a second receiving groove 520 on the side near the outer groove wall 120, and the outer groove wall 120 has a third receiving groove 530. One end of the second elastic member 420 is placed in the second receiving groove 520, and the other end of the second elastic member 420 is placed in the third receiving groove 530. The second elastic member 420 is positioned by the second receiving groove 520 and the third receiving groove 530 to prevent the second elastic member 420 from shifting position.
[0047] There are two pressing parts 200 and two fastening parts 300. The two pressing parts 200 are opposite each other, and the two fastening parts 300 are opposite each other. The two pressing parts 200 and the two fastening parts 300 form a ring.
[0048] The outer wall 120 of the mounting groove 110 has two sections, forming two openings 140 between the two sections of the outer wall 120. The inner wall 130 of the mounting groove 110 also has two sections. Two snap fasteners 300 correspond to the positions of the two sections of the outer wall 120, and two pressing elements 200 correspond to the positions of the two sections of the inner wall 130.
[0049] The pressing member 200 has a first inclined surface 220 on the side near the fastener 300, and the fastener 300 has a second inclined surface 320 on the side near the pressing member 200. The first inclined surface 220 and the second inclined surface 320 abut against each other. When the pressing member 200 moves toward the inside of the cover 100, the first inclined surface 220 presses against the second inclined surface 320, so that the pressing member 200 pushes the fastener 300 toward the outside of the cover 100.
[0050] Reference Figure 3 It is understandable that the pressing member 200 has a first inclined surface 220 on both sides, and the pressing member 200 has a first inclined surface 220 on the side near one of the fasteners 300, and another first inclined surface 220 on the side near the other fastener 300.
[0051] The fastener 300 has a second inclined surface 320 on each side. The fastener 300 has a second inclined surface 320 on the side closer to one pressing member 200 and another second inclined surface 320 on the side closer to the other pressing member 200.
[0052] For the first inclined surface 220, the side of the first inclined surface 220 near the outer groove wall 120 protrudes from the side of the first inclined surface 220 near the inner groove wall 130, and the first inclined surface 220 is inclined towards the inside of the pressing member 200.
[0053] For the second inclined surface 320, the side of the second inclined surface 320 near the inner groove wall 130 protrudes from the side of the second inclined surface 320 near the outer groove wall 120, and the second inclined surface 320 is inclined towards the outside of the fastener 300.
[0054] The inner side of the fastener 300 is provided with a protruding edge 310. The protruding edge 310 protrudes from the inner groove wall 130 of the mounting groove 110. The protruding edge 310 is fastened to the bayonet 11 of the lens 10.
