Description of reference numerals:
the focusing device comprises a focusing fixing tube 1, a lifting groove 11, a focusing lifter 2, a guide rod 21, a second lens 22, an internal thread 23, a fixing ring 3, a focusing screwing switch component 4, a first lens 41, an external thread 42, a lens cover 5, an internal cover 51, an external cover 52, a heat dissipation hole 53, a third lens 54 and a screw hole 55.
Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Referring to fig. 1 to fig. 6, the following technical solutions are adopted in the present embodiment: the focusing device comprises a focusing fixing tube 1, a focusing lifter 2, a fixing ring 3, a focusing screwing switch component 4 and a lens cover 5; fixed pipe 1's of focusing lateral wall circumference equipartition have several lift groove 11, focusing lift 2's outer wall circumference equipartition has several guide bar 21, focusing lift 2 interior one end is provided with internal thread 23, second lens 22 is installed to the other end, focusing is twisted and is installed first lens 41 in screwing switch 4, focusing is twisted and is twisted the outside of screwing switch 4 and be provided with external screw thread 42, lens lid 5 comprises inner cup 51 and enclosing cover 52, several third lens 54 is installed to the circumference equipartition on the inner cup 51, fixed pipe 1 of focusing is installed to the hole of inner cup 51, install focusing lift 2 through lift groove 11 and guide bar 21 cooperation in the fixed pipe 1 of focusing, focusing lift 2 internal fixation has solid fixed ring 3, focusing lift 2 is twisted through internal thread 23 and external screw thread 42 and is twisted switch part 4 and connect soon.
The focusing screwing switch positioned outside is cylindrical, wherein the outward end of the focusing screwing switch is a screwing switch, and the outward end inside the screwing switch is provided with a first lens and is fixed in the first lens. The focusing screwing switch is annular and protrudes outwards, and the surface of the focusing screwing switch is provided with a concave-convex groove, so that manual rotation focusing operation is facilitated. Threads are arranged around the outer side of the focusing screwing switch, the threads on the outer side are just matched with the threads on the inner wall of the focusing lifting groove, and the focusing screwing switch component can be embedded into the focusing lifting groove in a rotating mode. The focusing lifting groove is internally provided with a second lens, and the second lens is fixed inside the focusing lifting groove by a fixing ring. Three protruding guide rods are further arranged on the edges of the focusing lifting grooves, and the guide rods can ascend or descend in the three lifting grooves of the focusing fixing tube to move downwards. The focusing device has the advantages that the first lens is fixed on the focusing screwing switch component, the second lens driving the focusing lifting groove is screwed manually, and the second lens moves forwards or backwards on the lifting groove of the focusing fixing tube, so that the first lens and the second lens can change the distance, and the focusing operation is realized.
During the focusing operation, the focusing screwing switch buckle with the built-in first lens is fixed on the lens cover, so that the focusing screwing switch can not be screwed out of the lamp body and damaged no matter which direction the focusing screwing switch is screwed. In addition, the focusing device does not have a traditional external manual transmission focusing device, and the whole projection or the inner recess of the lens on the stage lamp can not be caused during focusing, so that the advantages of attractiveness and the like are realized. The used material of this focusing lens only relates to focusing switch, first lens, the noisy, second lens, solid fixed ring, the fixed pipe of focusing lift, realizes simple structure, can its manufacturing cost of greatly reduced, and the device is small, and the quality is light, makes the device portable more. The focusing operation process only needs to manually rotate the focusing screwing switch without using electric drive, so that the energy-saving effect can be achieved.
In the moving process of the focal lens, the smooth and stable movement is ensured, and the imaging effect is ensured. At present, the conventional stage lamp focusing device has the defects that the optical centers of a lens assembly such as a lens and an amplifying structure above the lens assembly are not on the same straight line, and the focusing or amplifying lens is easy to shift in the moving process by adopting the moving mode, so that the imaging effect is influenced
The inner cover 51 is provided with a heat radiation hole 53.
The outer cover 52 is provided with a screw hole 55.
The basic principles and main features of the invention and the advantages of the invention have been shown and described above.
