Description

Technical Field

[0001] The utility model relates to the field of snoot tube technology, in particular to a detachable and rotatable snoot tube. Background Art

[0002] Snoots are commonly known as pig mouths, also known as focusing tubes. They are a lampshade structure that uses a cone to restrict the range of light illumination. They are usually used in the field of photography to better capture the shape and outline of objects. A small honeycomb grid can make the emitted light appear in a grid shape and produce heavier shadows, which is convenient for special modeling. Snoots are mostly used for backgrounds, hair lights, and other parts that require concentrated light spots.

[0003] The use of a snoot needs to be coordinated with a photographic light (i.e., a light source). The main structure of a current snoot includes a body and a bayonet, which is arranged at the rear end of the body and is used to be clamped and mounted with the mounting opening of the photographic light. In the prior art, most snoots have an integral, non-detachable connection structure with the bayonet and the body, that is, one type of snoot corresponds to one type of photographic light. When a photographic light of another type needs to be replaced, the snoot with another type of bayonet needs to be replaced as a whole, and the cost of use is very high.

[0004] Therefore, there are also snoots with replaceable bayonet parts on the market. The bayonet parts are screwed to the body through internal and external threads, which can solve the above problems. However, after the external and internal threads are locked and fixed, the bayonet parts and the body are fixed and cannot rotate. Since the body is provided with a projection component, the projection component is used to produce a light output shape, so the projection component cannot be rotated to adjust the angle, and thus the angle adjustment of the light output shape cannot be achieved, which brings inconvenience to the use. Therefore, it is necessary to improve the current snoot. Utility Model Content

[0005] In view of this, the present invention aims to solve the defects in the prior art, and its main purpose is to provide a detachable and rotatable snoot, which can effectively solve the problem that the existing snoot cannot adjust the angle of the light output shape.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A detachable and rotatable snoot includes a body and a bayonet; the bayonet is arranged at the rear end of the body; the bayonet is detachably mounted on the rear end of the body through a rotation positioning mechanism, the rotation positioning mechanism axially positions the bayonet, and the bayonet is rotatably arranged relative to the body.

[0008] As a preferred solution, the rear end of the main body has an inner fitting portion, and the front end of the bayonet piece has an outer fitting portion, which can be rotatably fitted outside the inner fitting portion, and the rotation positioning mechanism is arranged between the inner fitting portion and the outer fitting portion, with a simple structure and stable and reliable installation.

[0009] As a preferred solution, the outer wall of the inner fitting part is recessed with a first annular guide groove, and the inner and outer side surfaces of the outer fitting part are penetrated with screw holes. The rotation positioning mechanism is a screw, which is screwed into the screw hole from the outside to the inside. The inner end of the screw extends into the first annular guide groove for positioning and can be movably arranged back and forth along the first annular guide groove. The structure is simple and easy to assemble.

[0010] As a preferred solution, the outer wall of the inner fitting part is recessed with a mounting hole, and the inner wall of the outer fitting part is recessed with a second annular guide groove. The rotation positioning mechanism is a marble, which can be elastically and movably installed in the mounting hole. The marble protrudes out of the outer wall of the inner fitting part and is elastically positioned with the second annular guide groove, and the marble can be movably arranged back and forth along the second annular guide groove, so the structure is simpler and the assembly is more convenient.

[0011] As a preferred solution, the mounting holes are multiple and evenly spaced around the circle, and the aforementioned marbles are provided in each mounting hole. Each marble protrudes out of the outer wall of the inner fitting portion and is elastically positioned with the second annular guide groove, and the multiple marbles can be arranged to move back and forth along the second annular guide groove, so that the connection is more stable and reliable, and the rotation movement is smoother.

[0012] As a preferred solution, the inner fitting portion is connected to a barrel, in which a first lens is arranged, and the barrel extends into and is suspended in the bayonet piece. In this way, when replacing the bayonet piece, there is no need to replace the barrel and the first lens, making the replacement of the bayonet piece simpler, faster and much more trouble-free.

[0013] As a preferred solution, an internal thread is provided in the rear end opening of the inner sleeve portion, and an external thread is provided at the front end of the cylinder body. The external thread is screwed and fixed with the internal thread to facilitate assembly and disassembly.

[0014] As a preferred solution, a projection component is provided on the main body for changing the light output shape to achieve a desired light output effect.

[0015] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0016] By setting a rotation positioning mechanism, the bayonet piece can be removably axially positioned at the rear end of the main body by means of the rotation positioning mechanism, so that the bayonet piece can be replaced according to the needs of use to adapt to different models of photographic lights. The replacement cost is low and the product has stronger versatility. At the same time, the bayonet piece is rotatably arranged relative to the main body, and the main body can be rotated relative to the bayonet piece as needed, thereby easily realizing the angle adjustment of the light output shape, which brings great convenience to use.
