[0049] Please refer to Figure 1 , Figure 5 , Figure 10 and Figure 17 As shown in
[0050] Please refer to Figures 1 to 4 shown, a macro lamp provided by the present invention includes an adapter 1 and a macro lamp body 2. The adapter 1 is in a ring shape and is used to be sleeved on a photographic lens. One or more macro lamp bodies 2 are provided and are respectively clamped on the adapter 1. According to the needs of the photographic effect, an appropriate number of macro lamp bodies 2 can be selected to be distributed on the adapter 1, and each macro lamp body 2 can be adjusted individually to form a variety of different photographic effects.
[0051] Please refer to Figure 1 , the adapter 1 includes an annular body 11, an unlocking block 12 and an elastic member 13.
[0052] A circumferential limiting flange 110 is provided on the circumferential side of the annular body 11. The limiting flange 110 protrudes from the side wall of the annular body 11 along the axial direction of the lens hole 10, enabling the annular body 11 to form a structure with a thick edge and a thin middle in its axial direction. When the macro lamp body 2 is clamped on the annular body 11, the limiting flange 110 can radially limit the macro lamp body 2 clamped on the annular body 11, preventing the macro lamp body 2 from radially detaching from the annular body 11. At the same time, when the macro lamp body 2 is clamped on the annular body 11, it can circumferentially move around the annular body 11 along the limiting flange 110, thereby adjusting its position clamped on the annular body 11.
[0053] Please refer to Figures 2 to 4 , an unlocking block 12 is provided on the limiting flange 110 and can move relative to the limiting flange 110. For example, an absent position groove 14 is formed in the annular body 11 at the limiting flange 110. The absent position groove 14 can be in an arc segment shape, that is, corresponding to a partial arc segment of the limiting flange 110; the unlocking block 12 is arranged in the absent position groove 14, and the unlocking block 12 can be in an arc segment shape adapted to the absent position groove 14. The axial thickness of the unlocking block 12 can be smaller than the axial thickness of the absent position groove 14, so the unlocking block 12 can move in the absent position groove 14. When the unlocking block 12 moves relative to the limiting flange 110 in the absent position groove 14, it can approach or move away from the limiting flange 110, thereby adjusting the axial thickness of the adapter 1 at the unlocking block 12. When the axial thickness is smaller than the entrance width of the clamping component of the macro lamp body 2, the macro lamp body 2 can enter from the unlocking block 12 and be clamped on the annular body 11. Since the entrance width of the clamping component of the macro lamp body 2 is smaller than the axial width of the limiting flange 110, the macro lamp body 2 can be limit-connected to the limiting flange 110. It can be understood that the unlocking block 12 can also be connected to the limiting flange 110 by means of hinge or slidable connection, etc., so as to change the axial thickness of the adapter 1 at the unlocking block 12 through relative movement.
[0054] Please refer to Figure 2 and Figure 3, an elastic member 13 is disposed between the annular body 11 and the unlocking block 12. The elastic member 13 is used to force the unlocking block 12 to move towards the side away from the limiting flange 110, so that a spaced-apart state is maintained between the unlocking block 12 and the annular body 11, increasing and maintaining the axial width of the adapter 1 at the unlocking block 12. Therefore, only under external pressure can the unlocking block 12 overcome the resistance of the elastic member 13 and approach the limiting flange 110, reducing the axial width of the adapter 1 at the unlocking block 12. For example, the elastic member 13 can be disposed in the missing slot 14 by clamping, so that both ends of the elastic member 13 abut against the inner wall of the missing slot 14 on the annular body 11 and the unlocking block 12 respectively. Under external pressure, the unlocking block 12 is gradually pressed by the external force and approaches the missing slot 14 and the limiting flange 110, and the elastic member 13 is gradually compressed and deformed; when the external force disappears, the elastic member 13 returns to its original shape, forcing the unlocking block 12 to move away from the missing slot 14 and the limiting flange 110, restoring the original state, increasing and restoring the maximum axial width of the adapter 1 at the unlocking block 12. At this time, the maximum axial width is greater than the entrance width of the clamping member of the macro lens body 2, so the clamping member of the macro lens body 2 cannot disengage from the annular body 11 at the unlocking block 12.
[0055] The unlocking block 12 and the elastic member 13, as an unlocking structure, can move relative to the limiting flange 110 to adjust the axial thickness of the adapter 1 at the unlocking structure, so that the macro lens body 2 can be limitedly connected to the limiting flange 110 at the unlocking structure. The unlocking structure can also adopt other structures to change the axial thickness of the adapter 1 at the unlocking structure. For example, the unlocking structure adopts a radial telescopic method to withdraw from the limiting flange 110, making the limiting flange 110 vacant, and then changing the axial thickness of the adapter 1 at the unlocking structure, so that the macro lens body 2 can be limitedly connected to the limiting flange 110 at the unlocking structure.
[0056] Please refer to Figure 2 and Figure 3 , in some embodiments, the annular body 11 includes a front cover 111, a rear cover 112 and an adapter ring 113 that are spliced front and back along the axis. Both the front cover 111 and the rear cover 112 are annular structures, and the front cover 111 and the rear cover 112 can be spliced with each other along the axis. The front cover 111 and the rear cover 112 can be locked together by means of buckles or screws. The missing slot 14 is provided on the rear cover 112. In some embodiments, the missing slot 14 can also be provided on the front cover 111.
[0057] The adapter ring 113 is in a ring structure, and there is a ring-shaped flange 1131 bent outward at its edge. The diameter of the ring-shaped flange 1131 is greater than the inner diameters of the front cover 111 and the rear cover 112, and less than the outer diameters of the front cover 111 and the rear cover 112. When the front cover 111 and the rear cover 112 are spliced and installed, the ring-shaped flange 1131 of the adapter ring 113 can be clamped between the inner peripheral edges of the front cover 111 and the rear cover 112, so that the adapter ring 113 is clamped and fixed at the center of the front cover 111 and the rear cover 112. The central hole of the adapter ring 113 is the lens hole 10 of the ring-shaped body.
[0058] It can be understood that in some embodiments, the component of the adapter ring 113 can also be omitted, and the inner peripheral edge of the front cover 111 or the rear cover 112 can be directly connected to the photographic lens. That is, the central hole of the front cover 111 or the rear cover 112 can be used as the lens hole 10 of the ring-shaped body and sleeved on the photographic lens.
[0059] Still referring to Figure 2 and Figure 3 , the peripheral edges of the front cover 111 and the rear cover 112 can respectively protrude along the axial direction of the ring-shaped body 11, so that after the front cover 111 and the rear cover 112 are spliced and combined, a limiting flange 110 is formed at the peripheral edge.
[0060] A notch 1111 is provided at the peripheral edge of the front cover 111, so that after the front cover 111 and the rear cover 112 are spliced and combined, an absent position groove 14 is formed at the notch 1111. It can be understood that the notch 1111 can also be provided on the rear cover 112.
[0061] Please refer to Figure 2 , in some embodiments, at the absent position groove 14, an activity space communicating with the absent position groove 14 is formed between the front cover 111 and the rear cover 112. At both ends of the unlocking block 12 in the circumferential direction of the ring-shaped body 11, an ear part 121 is respectively protruded, and the ear part 121 is clamped in the activity space between the front cover 111 and the rear cover 112, so that the ear part 121 can axially move in the activity space along the axial direction of the ring-shaped body 11. During the process of the unlocking block 12 axially moving in the activity space with its ear part 121, the unlocking block 12 can approach or move away from the limiting flange 110 and the absent position groove 14.
[0062] Please refer to Figure 2 and Figure 11, Further, in some embodiments, a guiding post 114 is provided in the space between the front cover 111 and the rear cover 112. The guiding post 114 extends along the axial direction of the annular body 11. The guiding post 114 integrally extends from the front cover 111 to the rear cover 112, or can also integrally extend from the rear cover 112 to the front cover 111. The ear portions 121 at both ends of the unlocking block 12 are movably sleeved on the guiding post 114. By using the guiding post 114 to guide the movement of the unlocking block 12, the movement of the unlocking block 12 closer to or away from can be made more stable and smooth.
[0063] Refer to Figure 3 , In some embodiments, at the absent slot 14, a first positioning protrusion 1121 protrudes from the side wall of the rear cover 112 facing the unlocking block 12, and a second positioning protrusion 120 opposite to the first positioning protrusion 1121 protrudes from the side wall of the unlocking block 12 facing the rear cover 112. The elastic member 13 is a spring, and both ends of the spring are respectively sleeved on the first positioning protrusion 1121 and the second positioning protrusion 120. When there are multiple springs in the absent slot 14, multiple groups of first positioning protrusions 1121 and second positioning protrusions 120 can be correspondingly provided on the rear cover 112 and the unlocking block 12. Under the pressure of an external force, the spring is compressed. When the first positioning protrusion 1121 abuts against the second positioning protrusion 120, the axial thickness of the adapter 1 at the unlocking block 12 is the smallest and is less than the entrance width of the clamping member of the macro lens body 2, as Figure 7 and Figure 8 shown; when the external force disappears, the spring resets, and the first positioning protrusion 1121 and the second positioning protrusion 120 move away from each other. At this time, the axial thickness of the adapter 1 at the unlocking block 12 is the largest and is greater than the entrance width of the clamping member of the macro lens body 2, as Figure 6 and Figure 11 shown.
[0064] Please refer to Figures 2 to 4 , In some embodiments, annular grooves 115 are recessed on the axial outer walls of both the front cover 111 and the rear cover 112. The annular groove 115 on the axial outer wall of the front cover 111 and the annular groove 115 on the axial outer wall of the rear cover 112 are distributed oppositely. The annular groove 115 is located between the limiting flange 110 and the central holes of the front cover 111 and the rear cover 112. After the front cover 111 and the rear cover 112 are spliced and combined, the annular groove 115 is formed on the axial side wall of the annular body 11. The annular groove 115 is located between the limiting flange 110 of the annular body 11 and the lens hole 10, and the annular groove 115 is communicated with the absent slot 14. The annular groove 115 can be used for the macro lens body 2 clamped on the annular body 11 to move circumferentially on the annular body 11, making the axial movement of the macro lens body 2 smoother, and can also make the macro lens body 2 be clamped on the annular body 11 more stably.
[0065] In some embodiments, the unlocking block 12 is provided with a convex surface 122 and a concave surface 123 in a step structure on the side facing away from the missing groove 14. The convex surface 122 protrudes from the concave surface 123 along the axial direction of the annular body 11 and extends in a direction away from the missing groove 14; and in the radial direction of the annular body 11, the convex surface 122 is located radially outside the concave surface 123. Figure 17 As shown, when the external force disappears and the elastic member 13 is naturally restored, the convex surface 122 is opposite to the limiting flange 110, and the missing part of the limiting flange 110 can be filled; at the same time, the concave surface 123 can be opposite to the annular groove 115, and at this time, the concave surface 123 can be flush with the groove surface of the annular groove 115, so that the macro lamp body 2 can move axially on the annular body 11 smoothly.
[0066] See also Figure 15 and Figure 16 In some embodiments, a positioning groove 116 is recessed on the outer peripheral wall of the above-mentioned back cover 112. A plurality of positioning grooves 116 may be provided and arranged at intervals in the circumferential direction. When the macro light body 2 is clamped on the annular body 11, the positioning groove 116 can be used to engage with the components in the macro light body 2 so that the macro light body 2 is fixed at the positioning groove 116. That is, the positioning groove 116 can be used as a limiting portion, which is used to engage with the macro light body 2 to prevent the macro light body 2 from moving circumferentially on the limiting flange 110, so that the macro light body 2 is stably clamped on the annular body 11. It can be understood that the limiting portion can adopt an outward convex structure, which can also be engaged with the components in the macro light body 2 to achieve circumferential limiting of the macro light body 2.
[0067] See also Figures 12 to 14 The macro light body 2 includes a host 21 and a connector 22 .
[0068] The host 21 is provided with a light source 211, which can be used to illuminate or fill in the light for the object to be photographed. The host 21 is hinged on the connector 22, and the irradiation angle of the light on the host 21 can be adjusted separately through the hinged connection, so as to facilitate the separate adjustment of the light effect of the macro light body 2.
[0069] One end of the connector 22 is provided with a pin shaft 221, and it can be hinged to the host 21 through the pin shaft 221. The other end of the connector 22 forms a clamping space 222, and it clamps on the annular body 11 of the adapter 1 through the clamping space 222. The entrance width of the clamping space 222 is smaller than the axial thickness of the adapter 1 at the limiting flange 110. During the movement of the unlocking block 12 relative to the missing slot 14, the axial thickness of the adapter 1 at the unlocking block 12 can be smaller than the entrance width of the clamping space 222. At this time, the connector 22 can enter through the clamping space 222, enter from the unlocking block 12 and clamp on the annular body 11, and perform circumferential movement on the annular body 11. For reference, Figure 5 and Figure 10 as shown
[0070] Please refer to Figure 14 As shown, in some embodiments, a receiving cavity 223 is further provided in the above-mentioned connector 22. The receiving cavity 223 is communicated with the clamping space 222, and the receiving cavity 223 is located on the side of the clamping space 222 away from its entrance.
[0071] A limiting block 23 and a first reset member 24 are arranged in the receiving cavity 223.
[0072] The limiting block 23 is movably arranged in the receiving cavity 223, and the limiting block 23 can move along the receiving cavity 223 to approach or move away from the clamping space 222.
[0073] A protruding portion 231 protrudes from the side of the limiting block 23 close to the clamping space 222. When the limiting block 23 moves toward the side close to the clamping space 222, the protruding portion 231 can extend into the clamping space 222 and be engaged with the positioning groove 116 on the outer peripheral wall of the annular body 11.
[0074] It can be understood that if the positions of the protruding portion 231 and the positioning groove 116 can be interchanged, that is, the protruding portion 231 is arranged on the outer peripheral wall of the annular body 11, and the positioning groove 116 is opened on the side of the limiting block 23 close to the clamping space 222. When the limiting block 23 moves toward the side close to the clamping space 222, the positioning groove 116 on the limiting block 23 can extend into the clamping space 222 and be engaged with the protruding portion 231 on the outer peripheral wall of the annular body 11.
[0075] The first reset member 24 is arranged in the receiving cavity 223. The first reset member 24 abuts against the limiting block 23 and forces the limiting block 23 to move toward the side close to the clamping space 222, so that the protruding portion 231 extends into the clamping space 222 and is engaged with the positioning groove 116 on the annular body 11. The first reset member 24 can be a spring. One end of the first reset member 24 abuts against the inner wall of the receiving cavity 223, and the other end abuts against the limiting block 23. The limiting block 23 is forced to move toward the side close to the clamping space 222 by the elastic force of the spring.
[0076] Please refer to Figure 13 and Figure 14 In some embodiments, the above-mentioned connector 22 may include a first clamping member 2201 and a second clamping member 2202.
[0077] The first clamping member 2201 and the second clamping member 2202 can be spliced and locked together by screws to form an integral body. When one ends of the first clamping member 2201 and the second clamping member 2202 are spliced, they are spaced apart from each other, and the above-mentioned clamping space 222 is formed therebetween. When the other ends of the first clamping member 2201 and the second clamping member 2202 are spliced, they enclose to form the above-mentioned accommodating cavity 223.
[0078] Please refer to Figure 13 In some embodiments, the macro lamp body 2 may further include an adjusting block 25 and a second reset member 26.
[0079] The adjusting block 25 is movably inserted into the side wall of the connector 22 and can extend laterally into the accommodating cavity 223 to abut against the limiting block 23. An inclined first inclined surface 232 is provided at the abutting position of the limiting block 23 and the adjusting block 25. The first inclined surface 232 gradually approaches the clamping space 222 in the direction from the outside of the limiting block 23 to the center of the limiting member. A mating second inclined surface 251 is provided at the abutting position of the adjusting block 25 and the limiting block 23.
[0080] When the adjusting block 25 gradually abuts against the limiting block 23 by extending laterally into the accommodating cavity 223, the adjusting block 25 can be in extrusion fit with the first inclined surface 232 through the second inclined surface 251, forcing the limiting block 23 to gradually move away from the clamping space 222, and further separating the protruding portion 231 from the positioning groove 116 and withdrawing from the clamping space 222. At this time, the connector 22 can move freely in the circumferential direction of the annular body 11. At the same time, when the protruding portion 231 withdraws from the clamping space 222, the first reset member 24 is synchronously compressed. Therefore, when the adjusting block 25 is separated from the limiting block 23, the protruding portion 231 will again extend into the clamping space 222 under the pressure of the first reset member 24.
[0081] The second reset member 26 is arranged between the adjusting block 25 and the connector 22. The second reset member 26 can be a spring. The inner end of the second reset member 26 abuts against the connector 22, and the outer end abuts against the adjusting block 25, forcing the adjusting block 25 to withdraw laterally from the accommodating cavity 223 and keeping the adjusting block 25 spaced apart from the limiting block 23. Therefore, only when an external force is applied, the adjusting block 25 can extend into the accommodating cavity 223 to abut against the limiting block 23.
[0082] In some embodiments, there are two sets of the adjusting block 25 and the second reset member 26, which are symmetrically arranged on both sides of the limiting block 23 in the left-right direction. During specific use, by relatively pressing the adjusting blocks 25 on both sides, the two adjusting blocks 25 can move transversely towards the center, respectively abutting against the inclined surfaces on both sides of the limiting block 23, so that the limiting block 23 gradually withdraws from the clamping space 222.
[0083] Please refer to Figure 15 and Figure 16 , when the macro lamp body 2 needs to move circumferentially on the annular body 11 during use, by pressing the adjusting block 25, the protruding portion 231 on the limiting block 23 can be separated from the positioning groove 116 on the annular body 11, and then the macro lamp body 2 can freely move circumferentially on the annular body 11. After releasing the adjusting block 25 again, the protruding portion 231 on the limiting block 23 can extend into the clamping space 222 and be engaged with the positioning groove 116, so that the macro lamp body 2 is circumferentially fixed on the annular body 11.
[0084] Please refer to Figure 10 and Figure 11 , when the macro lamp body 2 moves circumferentially and is clamped on the annular groove 115 of the annular body 11, that is, clamped in the area outside the unlocking block 12. At this time, the macro lamp body 2 can be radially limited by the limiting flange 110; at the same time, the macro lamp body 2 is circumferentially limited by the cooperation of the protruding portion 231 and the positioning groove 116. Thus, the macro lamp body 2 is stably fixed on the annular body 11.
[0085] Please refer to Figure 5 , when the macro lamp body 2 moves circumferentially and is clamped at the unlocking block 12 of the annular body 11, under the action of the elastic member 13, the axial thickness of the annular body 11 at the adjusting block 25 and the limiting flange 110 can still be greater than the entrance width of the clamping space 222 of the connector 22. That is, the macro lamp body 2 is radially limited by the cooperation of the adjusting block 25 and the limiting flange 110; at the same time, the macro lamp body 2 is circumferentially limited by the cooperation of the protruding portion 231 and the positioning groove 116. Thus, the macro lamp body 2 can also be stably fixed on the annular body 11.
[0086] Please refer to Figure 17 , when multiple macro lamp bodies 2 are clamped on the annular body 11, whether the macro lamp body 2 is clamped at the annular groove 115 or at the adjusting block 25, the macro lamp body 2 can be stably fixed on the annular body 11 to prevent it from falling off. At this time, the positions between the macro lamp bodies 2 can be adjusted as needed, and the irradiation angles of the individual macro lamp bodies 2 can be adjusted separately to achieve various different photographic lighting effects.
[0087] Please refer to Figures 5 to 9, when it is necessary to remove the macro lamp body 2 from the annular body 11, as Figure 5 and Figure 6 shown, the macro lamp body 2 can be circumferentially moved to the unlocking block 12 first. As Figure 7 shown, by pressing the unlocking block 12 through the connector 22, the axial thickness of the adapter 1 at the receiving block is reduced. As Figure 8 shown, when its axial thickness is less than the entrance width of the clamping space 222, the macro lamp body 2 can gradually exit the annular body 11 upward until the macro lamp body 2 is separated from the adapter 1, as Figure 9 shown.
[0088] Based on the above technical solutions, the embodiments of the present invention have at least the following advantages and positive effects:
[0089] In the macro lamp and its adapter 1 of the embodiments of the present invention, the adapter 1 includes an annular body 11, an unlocking block 12, and an elastic member 13. Among them, by using the lens hole 10 on the annular body 11, the adapter 1 can be assembled on the lens of the photographic device; by using the limiting flange 110 on the periphery of the annular body 11, the macro lamp body 2 clamped on the annular body 11 can be limited on the annular body 11 to prevent the macro lamp body 2 from radially disengaging from the annular body 11 along the annular body 11. And the limiting flange 110 allows the macro lamp body 2 to circumferentially move on the annular body 11, and the position of the macro lamp body 2 on the annular body 11 can be adjusted by circumferential movement, thereby adjusting the photographic effect.
[0090] In the adapter 1, by using the limiting flange 110 on the annular body 11 to be movably matched with the unlocking block 12, and the unlocking block 12 moves relative to the limiting flange 110, approaching or moving away from the limiting flange 110, the axial thickness of the adapter 1 at the unlocking block 12 can be adjusted, so that the macro lamp body 2 can enter the limiting flange 110 from the unlocking block 12 and be limit-connected with the limiting flange 110, and then be clamped on the annular body 11. At the same time, the elastic member 13 can force the unlocking block 12 to move toward the side away from the limiting flange 110, so that the unlocking block 12 can only approach the limiting flange 110 under external pressure. Therefore, when the unlocking block 12 is not under external pressure, it is very difficult for the macro lamp body 2 clamped on the annular body 11 to disengage from the adapter 1, which can effectively prevent the macro lamp body 2 from disengaging from the adapter 1.
[0091] In addition, multiple macro lamp bodies 2 can enter and be clamped on the annular body 11 from the unlocking block 12 to form an annular light source 211 around the lens; and each macro lamp body 2 can be individually adjusted, and various different photographic lighting effects can be achieved according to needs.
[0092] While the invention has been described with reference to several exemplary embodiments, it should be understood that the terms used are illustrative and exemplary rather than restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above-described embodiments are not limited to any of the foregoing details, but rather should be broadly construed within the spirit and scope defined by the appended claims, and thus all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
