Description

Technical Field

[0001] The utility model belongs to the technical field of photographic equipment, and particularly relates to a Bowens Mount and a photographic apparatus having the same. Background Art

[0002] The Bowens Mount, also known as the Bowens Mount or the Bowens bayonet mount, is a common interface standard for lights and accessories, especially widely used in photographic equipment. It was initially invented by British photographer George Bowens in the 1950s and is mainly used to connect different types of flashlights and photographic equipment. The design feature of the Bowens Mount is that there are three limiting bayonets in front of the lamp head, and these limiting bayonets can be inserted and replaced by different-shaped lamp shade accessories such as softboxes, soft umbrellas, reflective umbrellas, snoots, standard diffusers, and parabolic reflectors. Thus, photographers can conveniently replace different lamp shade accessories according to creative needs, thereby changing the light quality and the illumination range of the light source.

[0003] At present, as a widely used interface standard, the Bowens Mount has been adopted by many photographic equipment manufacturers. In photography, the unification of the flash interface standard enables photographers to more conveniently replace and combine different photographic equipment, thereby improving shooting efficiency and creative flexibility.

[0004] However, due to differences in size, the standard-specification Bowens Mount is not suitable for some types of lamp shade accessories. Therefore, when selecting and replacing photographic equipment, it is necessary to ensure that the used Bowens Mount matches the lamp shade accessories, which also makes it necessary for users to frequently replace and combine different Bowens Mounts and lamp shade accessories according to photographic needs, which is rather troublesome. Summary of the Utility Model

[0005] In order to overcome the defects of the above-mentioned prior art, the utility model provides a Bowens Mount, which includes a base, and a rotatable movable ring is carried on the base. At least two movable fixing parts for detachably connecting with an external lamp shade are arranged on the base around the movable ring.

[0006] The inner ends of the movable fixing parts are movably connected to the base, and each movable fixing part is movably connected to the movable ring through a movable pull rod, so that when any one of the movable fixing parts moves relative to the movable ring, the remaining movable fixing parts are driven by the movable ring to move synchronously to adapt to connecting external lamp shades of different sizes.

[0007] Specifically, the base also bears an inner ring that can rotate relative to the base and an outer ring that can be stretched in a direction perpendicular to the base. The outer surface of the inner ring is provided with a first inclined portion, and the inner surface of the outer ring is provided with a second inclined portion that is in close contact with the first inclined portion. The first inclined portion and the second inclined portion are an inclined protrusion and an inclined groove respectively, for making the stretching of the outer ring linked with the rotation of the inner ring.

[0008] Optionally, the movable ring is connected to the inner ring or integrally formed with the inner ring, so that the movable ring rotates synchronously with the inner ring.

[0009] Further, a plurality of limiting posts are provided on the outer surface of the outer ring, and a guiding member for accommodating the limiting posts and guiding the stretching direction of the limiting posts is provided on the base.

[0010] Preferably, the extending direction of the guiding member is perpendicular to the base. The guiding member includes two guiding posts. A protrusion is provided at the bottom end of the limiting post. A sliding groove allowing the limiting post to slide is provided on the inner side of each guiding post, and a clamping groove for blocking the protrusion is provided at the top end of the sliding groove.

[0011] Preferably, the movable ring is fixedly connected with a rotating handle for driving the movable ring to rotate, and the rotating handle protrudes from the base.

[0012] Further, a limiting bayonet for fixing the external lamp shade, a first limiting member protruding from the limiting bayonet, and a first elastic member arranged between the movable fixing portion and the first limiting member are provided at the outer end of each movable fixing portion. The first elastic member is used to provide an elastic force for the first limiting member, so that the first limiting member plays a limiting role on the external lamp shade when the external lamp shade is fixed by the limiting bayonet.

[0013] Further, the base is provided with a receiving groove for receiving the rotating handle and playing a limiting role on the rotating handle.

[0014] Preferably, the base further includes a second limiting member protruding from the receiving groove and a second elastic member arranged at the bottom end of the second limiting member. The second elastic member is used to provide an elastic force for the second limiting member, so that the second limiting member plays a limiting role on the rotating handle when the movable fixing portion connects the external lamp shade.

[0015] The present utility model also proposes a photographic apparatus, and the photographic apparatus includes a Bowens mount as described above.

[0016] The present utility model has at least the following beneficial effects:

[0017] The bayonet mount proposed by the present utility model increases the flexibility and operability of the connection and fixation between the bayonet mount and the lamp shade by providing a rotatable movable ring on the base and arranging a plurality of movable fixing parts around the movable ring. As a result, users can conveniently adjust and fix the position and angle of the appliance, providing flexibility and diverse operation options for different requirements during the photography process.

[0018] Furthermore, in the solution proposed by the present utility model, the outer ring can be stretched in the vertical direction. At the same time, it cooperates with the inner ring through the inclined part structure, and a rotating handle is provided on the inner ring, providing users with a variety of adjustment methods with different precisions and conveniences. The setting of the limit post and the guide can ensure that the appliance is accurately positioned and moved in the vertical direction during use, and effectively guarantee the connection stability between the outer ring and the overall structure. The settings of the two limit parts and the elastic parts can respectively limit the lamp shade and the rotating handle, ensuring the stability of the connection state between the bayonet mount and the lamp shade.

[0019] Therefore, the present utility model proposes a bayonet mount and a photographic appliance having the same. Through the setting of the rotatable movable ring and the movable fixing parts, the solution proposed by the present utility model can accommodate various types of lamp shades. The design of the limit bayonet can conveniently fix the lamp shade, reducing the adjustment and installation time, improving work efficiency, and allowing users to cooperate with various lamp shades of different specifications according to needs to achieve different shooting effects, thereby improving the diversity and flexibility of photographic creation.

[0039] Embodiment 1

[0040] See Figure 1-8 , this embodiment proposes a bayonet socket, which is arranged on a device for photography and is used to fix the lampshade. The bayonet socket proposed in this embodiment includes a base 1, on which a rotatable movable ring 5 is carried, and at least two movable fixing parts 3 for detachably connecting with an external lampshade are arranged around the movable ring 5 on the base 1;

[0041] The inner ends of the movable fixing parts 3 are movably connected to the base 1, and a limit bayonet 32 for fixing the lampshade is arranged at the outer end of each movable fixing part 3. The limit bayonet 32 can realize the fixed connection with the external lampshade. Each movable fixing part 3 is movably connected to the movable ring 5 through a movable pull rod 31, so that when any movable fixing part 3 moves relative to the movable ring 5, the remaining movable fixing parts 3 are driven by the movable ring 5 to move synchronously with the movement to adapt to connecting external lampshades of different sizes.

[0042] Thus, when the user pulls the outer end of any movable fixing part 3, the movable fixing part 3 will drive the movable ring 5 to rotate through the movable pull rod 31 connected thereto. Furthermore, the movable ring 5 drives the other movable pull rods 31 connected thereto to produce the same movement. Finally, when the user pulls the outer end of any movable fixing part 3, the outer ends of all the movable fixing parts 3 are synchronously driven to move outward, that is, the movable ring 5 and each movable fixing part 3 rotate relative to the base 1; when the outer end of the movable fixing part 3 moves outward, the position of the limit bayonet 32 of the movable fixing part 3 relative to the base 1 also changes synchronously, so that the bayonet socket proposed in this embodiment can cooperate with lampshades of various different specifications.

[0043] Preferably, a limit component for limiting the rotation angle of the movable pull rod 31 is also arranged at the connection between the movable fixing part 3 and the movable pull rod 31, and a groove for the movable pull rod 31 to move is correspondingly arranged on the base 1 to form clearance, so that the overall assembly of the bayonet socket proposed in this embodiment is more compact.

[0044] It should be noted that since the general design of the bayonet socket is to have three grooves in front of the lamp head, and the interfaces of most lampshades also cooperate with the bayonet socket having three limit grooves, therefore, in a specific embodiment, three movable fixing parts 3 are arranged equidistantly around the inner ring 2 on the base 1 of the bayonet socket proposed in this embodiment to form three limit bayonets 32 for fixing the lampshade;

[0045] Corresponding to the movable fixing parts 3 arranged equidistantly on the inner ring, the pull rod connection parts arranged on the movable ring 5 and connected to the movable pull rods 31 are also evenly distributed around the movable ring 5, so that the movable pull rods 31 and the movable ring 5 rotate synchronously to drive the closing amplitude and unfolding amplitude of each movable fixing part 31 relative to the base 1 to be consistent.

[0046] Preferably, the movable fixing part 3 further includes a first limiting member protruding from the limiting bayonet 32 and a first elastic member disposed between the movable fixing part 3 and the first limiting member. When the lamp cover is fixed to the movable fixing part 3, the lamp cover will exert a force on the first limiting member and compress the first elastic member. After the lamp cover is fixed to the movable fixing part 3, the elastic force provided by the first elastic member will reset the first limiting member, thereby playing a role in fixing the lamp cover. In this embodiment, the first limiting member is disposed at the base of the limiting bayonet 32, and the first limiting member includes a first top bead 33. In another embodiment, the first limiting member can also be disposed at the upper edge of the limiting bayonet 32.

[0047] Further, the base 1 also bears an inner ring 2 that can rotate relative to the base 1 and an outer ring 4 that can be stretched in a direction perpendicular to the base 1. The outer ring 4 is disposed around the outer circumference of the inner ring 2. The outer surface of the inner ring 2 is provided with a first inclined portion 21, and the inner surface of the outer ring 4 is provided with a second inclined portion 41 that is in close contact with the first inclined portion 21. Thus, the outer ring 4 can form a linkage with the inner ring 2. When the user stretches the outer ring 4 away from the base 1, it can synchronously drive the inner ring 2 to rotate and drive the outer ends of all the movable fixing parts 3 to move outward. Specifically, the first inclined portion 21 and the second inclined portion 41 are respectively an inclined protrusion and an inclined groove.

[0048] Optionally, the middle part of the movable fixing part 3 is rotatably connected to one end of the movable pull rod 31. The other end of the movable pull rod 31 is connected to a connecting portion disposed on the inner ring 2 and protruding inwardly of the inner ring 2, and is connected to the movable ring 5 to realize the connection between the movable ring 5 and the inner ring 2, so that the movable ring 5 and the inner ring 2 can rotate synchronously; see Figure 6 , the movable ring 5 and the inner ring 2 can also be integrally formed.

[0049] Optionally, see Figure 7 , the movable ring 5 and the inner ring 2 can also be independently provided.

[0050] In this embodiment, when the Bayonet Nut is in the retracted state, the outer ring 4 and the inner ring 2 have the same height relative to the base 1, and each movable fixing part 3 is in close contact with the outer surface of the outer ring 4. When the Bayonet Nut changes from the retracted state to the lifting and contracting state, the inner ring 2 and each movable fixing part 3 rotate relative to the base 1, and the limiting bayonets 32 of each movable fixing part 3 are synchronously unfolded relative to the base 1. At the same time, the rotation of the inner ring 2 will drive the outer ring 4 to rotate in the opposite direction and move away from the base 1. The height of the outer ring 4 of the Bayonet Nut in the lifting and contracting state relative to the base 1 is higher than the height of the inner ring 2 relative to the base 1.

[0051] In addition, by adjusting the telescopic length of the outer ring 4, the amount of light entering can be controlled, thereby adjusting the exposure of the photo. When the aperture is enlarged, the amount of light entering the lens increases, and the photo exposure increases; when the aperture is reduced, the light entering decreases, and the exposure decreases. The user can adjust the size of the aperture through the outer ring 4, so as to obtain the required exposure level under different light conditions and achieve the effect of taking clear and bright photos.

[0052] Specifically, a plurality of limit posts 42 are arranged on the outer surface of the outer ring 4, and a guide member 11 for accommodating the limit posts 42 and guiding the stretching direction of the limit posts 42 is arranged on the base 1. The guide member 11 can ensure that the outer ring 4 moves in a direction perpendicular to the base 1. In a specific embodiment, the extending direction of the guide member 11 is perpendicular to the base 1.

[0053] Furthermore, referring to Figure 8 , the guide member 11 includes two guide posts 111. A convex portion is arranged at the bottom end of the limit post 42. A sliding groove 112 allowing the limit post 42 to slide is arranged inside each guide post 111, and a clamping groove 113 for blocking the convex portion is arranged at the top end of the sliding groove 112. Through the arrangement of the sliding groove 112 and the clamping groove 113, it can be effectively ensured that the outer ring 4 does not fall off the base 1.

[0054] Preferably, the movable ring 5 is also fixedly connected with a rotating handle 22. The rotating handle 22 protrudes from the base 1. The user can also drive the movable ring 5 to rotate through the rotating handle 22, so as to drive the outer ends of all the movable fixing parts 3 to move outward or inward.

[0055] Furthermore, the base 1 is also provided with a receiving groove 12 for accommodating the rotating handle 22 and limiting the rotating handle 22. The rotation angle allowed by the receiving groove 12 for the rotating handle 22 is adapted to the movement amplitude of the movable pull rod 31. In this embodiment, one side of the receiving groove 12 is a convex portion, and the other side is the connecting portion of a movable fixing part 3 and the inner ring 2;

[0056] Similarly, the base 1 also includes a second limiting member protruding from the receiving groove 12 and a second elastic member arranged at the bottom end of the second limiting member. When the protection port in this embodiment changes from the storage state to the lifting and telescopic state, the rotating handle 22 will exert a force on the second limiting member and compress the second elastic member. After the protection port changes from the storage state to the lifting and telescopic state, the elastic force provided by the second elastic member will reset the second limiting member, so as to play a role in fixing the rotating handle 22; in this embodiment, the second limiting member includes a second top bead 13.

[0057] Embodiment 2

[0058] This embodiment provides a photographic apparatus. The Bowens mount proposed in Embodiment 1 of the photographic apparatus can flexibly install a lamp shade through a telescopic movable fixing part to cooperate with various lamp shades of different specifications and types.

[0059] Optionally, in addition to being able to cooperate with a lamp shade, the photographic apparatus can also cooperate with components such as a softbox, a soft light umbrella, a reflective umbrella, a beam projector, a standard diffuser, and a parabolic umbrella.

[0060] In summary, the present utility model provides a Bowens mount and a photographic apparatus having the same. The solution proposed by the present utility model can accommodate various types of lamp shades through the settings of a rotatable movable ring and a movable fixing part. The design of the limit bayonet can conveniently fix the lamp shade, reduce the adjustment and installation time, improve work efficiency, and allow users to cooperate with various lamp shades of different specifications according to needs to achieve different shooting effects, thereby improving the diversity and flexibility of photographic creation.

[0061] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
