Description

Technical Field

[0001] The invention relates to the technical field of stage lights, in particular to a single-motor multi-module optical mechanism capable of automatically resetting. Background Art

[0002] In the field of traditional stage lights, two motors are needed to control the movement of two structures, which takes up a lot of space, resulting in a large volume shell, a bulky appearance, and a large waste of stage space. It is extremely inconvenient and difficult to operate during installation and maintenance, which is particularly time-consuming and greatly increases labor costs. This increases the difficulty within the limited space of the original structure. In addition, during the design process, the distribution of various functional modules in the stage lights is often staggered, and the working noise is loud. In this way, sudden power failures often cause two or more reciprocating structures to collide with each other, especially zoom lens components and cut-in optical components (optical accessories outside the main light path need to be cut into components on the main light path), which seriously affects the layout effect of the entire stage.

[0003] Based on this, the present invention designs a single-motor multi-module optical mechanism that can automatically reset to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a single-motor multi-module optical mechanism that can automatically reset, so as to solve the problem raised in the above background technology that in the field of traditional stage lights, two motors are required to control the movement of two structures, which takes up a large space, resulting in a large volume shell, a bulky appearance, and a large waste of stage space. It is extremely inconvenient and difficult to operate during installation and maintenance, and it is particularly time-consuming, which greatly increases the labor cost. This increases the difficulty in the space where the structure is originally limited. In addition, during the design process, the distribution of various functional modules in the stage light is often staggered, and the working noise is loud. In this way, two or more reciprocating structures often collide with each other due to sudden power failure, especially zoom lens components and cut-in optical components (optical accessories outside the main light path need to be cut into components on the main light path), which seriously affects the layout effect of the entire stage.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatically reset single-motor multi-module optical mechanism, comprising a motor frame and a motor, the motor being fixedly mounted on the bottom of the motor frame, the top of the motor frame being fixedly connected to a hollow fixed seat plate, the right side of the fixed seat plate being fixedly connected to an extension frame extending to the right, the output end of the motor being sleeved and fixed to a turntable located at the upper part of the fixed seat plate, a reset spring being fixedly connected between the front side of the turntable and the right end of the extension frame, two groups of spaced-apart driving iron columns being fixedly connected to the top outer edge of the turntable, the left front side of the fixed seat plate and the left rear side of the extension frame being fixedly connected to limiting iron columns, a fixed sleeve being sleeved and fixed on the output end of the motor being arranged above the turntable, the lower end of the fixed sleeve being rotatably connected to a lower frosting sheet assembly, the upper end of the fixed sleeve being rotatably connected to an upper frosting sheet assembly, and a sealing plate being provided above the rotating part of the upper frosting sheet assembly.

[0010] Compared with the prior art, the beneficial effects of the present invention are: the present invention reduces the weight of the product, reduces the problem of excessive structural volume, and develops and designs a new transmission structure, which can drive two accessories to rotate by one motor, replacing the original structure that requires two motors. This structure not only realizes the automatic reset of the optical frosted sheet when the power is off, but also solves the problem that the original multiple optical frosted sheets require multiple motors to control by one motor.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-6The present invention provides a technical solution for an automatically reset single-motor multi-module optical mechanism: an automatically reset single-motor multi-module optical mechanism, comprising a motor frame 1 and a motor 2, wherein the motor 2 is fixedly mounted at the bottom of the motor frame 1, a hollow fixed seat plate 3 is fixedly connected to the top of the motor frame 1, an extension frame 4 extending to the right is fixedly connected to the right side of the fixed seat plate 3, an output end of the motor 2 is sleeved and fixed to a turntable 5 located on the upper part of the fixed seat plate 3, a reset spring 6 is fixedly connected between the front side of the turntable 5 and the right end of the extension frame 4, two groups of spaced driving iron columns 7 are fixedly connected to the top outer edge of the turntable 5, a limited position iron column 8 is fixedly connected to the left front side of the fixed seat plate 3 and the left rear side of the extension frame 4, a fixed sleeve 9 sleeved and fixed to the output end of the motor 2 is arranged above the turntable 5, a lower grinding sheet assembly 10 is rotatably connected to the lower end of the fixed sleeve 9, an upper grinding sheet assembly 11 is rotatably connected to the upper end of the fixed sleeve 9, and a sealing plate 12 is covered above the rotating part of the upper grinding sheet assembly 11.

[0023] Furthermore, the lower sanding sheet assembly 10 includes a first sanding sheet body 101, a first bearing 102 sleeved on the fixed sleeve 9 is fixedly connected to the left side of the first sanding sheet body 101, a first snap-in slot 103 that can be rotatably clamped on the front limiting iron column 8 is opened on the left front side of the first sanding sheet body 101, and a first magnet 104 and a second magnet 105 are fixedly connected to the left rear side of the first sanding sheet body 101; in the initial state, the first magnet 104 is attracted to the rear limiting iron column 8, and the second magnet 105 is located on the rotation path of the driving iron column 7 and is not attracted to the driving iron column 7.

[0024] Furthermore, the upper sanding sheet assembly 11 includes a second sanding sheet body 111, a second bearing 112 sleeved on the fixed sleeve 9 is fixedly connected to the left side of the second sanding sheet body 111, a second bayonet 113 rotatably clamped on the front side limiting iron column 8 is opened on the left front side of the second sanding sheet body 111, and a third magnet 114 and a fourth magnet 115 fixed on the second sanding sheet body 111 are respectively arranged on the rear side and the left side of the second bayonet 113; in the initial state, the rear side of the second sanding sheet body 111 abuts against the rear side limiting iron column 8, and a group of driving iron columns 7 are attracted to the fourth magnet 115; wherein, the front side limiting iron column 8 is located on the rotation path of the third magnet 114.

[0025] Furthermore, rubber sleeves are sleeved and fixed on the driving iron column 7 and the limiting iron column 8, which not only do not affect the attraction of the magnets, but also can reduce contact noise.

[0026] Furthermore, the circumferential wall of the rotating disk 5 is concave inwardly in an arc shape, so that the reset spring 6 is located in the arc concave shape when being stretched and rotated, which is beneficial to protecting the reset spring 6 .

[0027] A specific application of this embodiment is: the present invention is a single-motor multi-module optical mechanism that can automatically reset. When in use, the mechanism is in an initial state, such as Figure 4 , the control motor 2 is started, driving the turntable 5 to rotate clockwise, and the two groups of driving iron pillars 7 on the turntable 5 rotate accordingly. Since the fourth magnet 115 on the upper sanding sheet assembly 11 is attracted to a group of driving iron pillars 7, the upper sanding sheet assembly 11 rotates along with the turntable 5 until the third magnet 114 on the upper sanding sheet assembly 11 attracts the front limiting iron pillar 8. At this time, the mechanism completes the single-piece cutting, as shown in FIG. Figure 5 ;

[0028] The motor 2 continues to drive the turntable 5 to rotate, and the fourth magnet 115 is separated from the driving iron column 7. Then, another set of driving iron columns 7 will abut against the second magnet 105 on the lower sanding sheet assembly 10, pushing the lower sanding sheet assembly 10 to rotate, so that the first magnet 104 is separated from the limiting iron column 8 on the rear side of the attraction, until the lower sanding sheet assembly 10 is completely rotated to abut against the limiting iron column 8 on the front side, completing the cutting of the two sheets. Figure 6 ;

[0029] When resetting is required, the motor 2 is powered off, and the reset spring 6 that was stretched by rotation in the early stage will pull the turntable 5 to rotate, thereby driving the driving iron column 7 to rotate and push the lower sanding sheet assembly 10 and the upper sanding sheet assembly 11 to reset.
