Description

Technical Field

[0001] This utility model relates to the field of optical experimental system technology, and in particular to a lifting seat for an optical system. Background Technology

[0002] In the field of optical research and application, optical experimental systems play a crucial role. They serve as the fundamental platform for exploring optical phenomena, testing the performance of optical devices, and developing new optical technologies. These systems encompass multiple key components, including light sources, optical elements (such as lenses, mirrors, and filters), and detectors. By precisely controlling the position, angle, and other parameters of each component, they enable the simulation, observation, and analysis of processes such as light propagation, focusing, interference, and diffraction.

[0003] Because different optical experiments have different purposes and requirements—for example, when studying the imaging laws of lenses, it is necessary to precisely change the distance between the lens and the light source and detector to obtain a clear image and analyze its characteristics; in optical interference experiments, the angle and position of the reflecting mirror need to be finely adjusted to obtain stable interference fringes—it is essential to achieve the lifting and adjustment of optical components to accurately position and fix them at different heights. Currently, most commercially available devices for lifting and adjusting optical components are either electrically or manually adjustable, which is insufficient to meet diverse experimental needs. Furthermore, the transmission structure of these lifting and adjusting devices is exposed, making it highly susceptible to interference from external objects, collisions, and other factors, thus affecting the lifting accuracy and reducing the stability and reliability of the device.

[0041] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0042] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0043] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0044] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0045] refer to Figures 1 to 6 This utility model discloses a lifting base for an optical system, including a base 1, a lifting mechanism 2, and a lifting seat 3. The lifting mechanism 2 is disposed on the base 1 and includes a guide seat 21, a lifting body 23, a screw 22, and a dual-head motor 24. The guide seat 21 is provided with a vertically arranged guide rail 211, and the lifting body 23 is slidably connected to the guide rail 211. The screw 22 is rotatably disposed on the base 1, and is vertically arranged and threadedly connected to the lifting body 23. The dual-head motor 24 includes a motor body 241 and an output shaft 242 passing through the motor body 241. The two ends of the output shaft 242 are an output end 242a and a manual operation end 242b, respectively. The output end 242a is drivenly connected to the screw 22. The lifting seat 3 is connected to the lifting body 23 to realize synchronous movement of the lifting seat 3 and the lifting body 23.

[0046] In application, the optical element can be mounted on the lifting base 3. The screw 22 and lifting body 23 in the lifting mechanism 2 are connected by a threaded connection, which provides self-locking and high transmission accuracy. Simultaneously, combined with the sliding connection between the lifting body 23 and the guide rail 211, when the screw 22 rotates, due to the meshing action of the threads, the lifting body 23 will move linearly along the axis of the screw 22. This transmission method can accurately convert the rotational motion of the screw 22 into the linear motion of the lifting body 23 with high precision.

[0047] In addition, the screw 22 is driven to rotate by a dual-head motor 24. The output shaft 242 of the dual-head motor 24 can be rotated electrically or manually by rotating the manual operation end 242b, thereby realizing electric or manual adjustment of the height of the lifting seat 3. It should be noted that the dual-head motor 24 in this embodiment can refer to the prior art.

[0048] In the above scheme, the output end 242a of the dual-head motor 24 and the screw 22 can be driven by gear, belt or chain; specifically, in this embodiment, a synchronous belt is used to realize the transmission between the output end 242a of the dual-head motor 24 and the screw 22.

[0049] Thus, this embodiment achieves both electric and manual adjustment modes through the dual-head motor 24, allowing for flexible selection based on different experimental conditions. This overcomes the limitations of a single adjustment mode and meets diverse experimental needs. The lifting mechanism 2, composed of the guide seat 21, lifting body 23, and screw 22, has a compact structure. The sliding connection between the guide rail 211 and the lifting body 23, as well as the threaded connection between the screw 22 and the lifting body 23, ensures the stability and accuracy of the lifting process.

[0050] In some embodiments, such as Figures 2 to 4 As shown, the base 1 includes a base 11, a shell 12, and a bottom plate 13; the shell 12 is disposed above the base 11, so that a first transmission cavity 1a is formed above the base 11, and an opening is provided above the first transmission cavity 1a; a second transmission cavity 1b is formed by a recess at the bottom of the base 11, and a first transmission hole 111 and a second transmission hole 112 are provided on the base 11 for connecting the first transmission cavity 1a and the second transmission cavity 1b; the bottom plate 13 is disposed at the bottom of the base 11 to cover the second transmission cavity 1b; wherein, the lifting mechanism 2 is disposed above the base 11, at least a portion of the screw 22 passes through the first transmission hole 111 and enters the second transmission cavity 1b, and the output end 242a of the dual-head motor 24 passes through the second transmission hole 112 and enters the second transmission cavity 1b.

[0051] In this embodiment, the transmission structure between the dual-head motor 24 and the screw 22 is configured in the second transmission cavity 1b, and the transmission structure between the guide seat 21, the lifting body 23 and the screw 22 is configured in the first transmission cavity 1a, so as to achieve isolation and protection of the transmission structure, avoid easy external interference, and ensure the lifting adjustment accuracy.

[0052] In this embodiment, the base plate 13 and the base 11 are fixed together with screws. When it is necessary to maintain the transmission structure between the screw 22 and the dual-head motor 24, the base plate 13 can be disassembled to expose the second transmission cavity 1b.

[0053] More preferably, the lifting body 23 includes a slider 231 and a partition 232. The slider 231 is slidably connected to the guide rail 211 and threadedly connected to the screw 22. The top of the partition 232 is connected to the lifting seat 3. The guide seat 21 and the screw 22 are located on one side of the partition 232, and the dual-head motor 24 is located on the other side of the partition 232. An operation window 121 is provided on the side of the outer casing 12 corresponding to the manual operation end 242b of the dual-head motor 24.

[0054] In this embodiment, by opening an operation window 121, the manual operation end 242b of the dual-head motor 24 is exposed for manual adjustment. Furthermore, to prevent foreign objects from entering the first transmission cavity 1a through the operation window 121 and affecting the transmission structure between the guide seat 21, the lifting body 23, and the screw 22, a partition 232 is provided for isolation in this embodiment. This prevents the transmission structure between the guide seat 21, the lifting body 23, and the screw 22 from being directly exposed to the operation window 121, thereby reducing the negative impact of opening the operation window 121.

[0055] It should be noted that the partition 232 does not achieve absolute sealing and isolation of the first transmission cavity 1a. Rather, the partition 232 is placed between the screw 22 and the operating window 121 to provide a certain degree of barrier; it prevents foreign objects from passing through the operating window 121 and directly contacting the screw 22.

[0056] In the above scheme, for ease of manual adjustment, such as Figure 1 and Figure 4 As shown, the manual operation end 242b of the dual-head motor 24 is fixedly connected to a rotating wheel 243, the outer circumferential surface of which is provided with friction patterns. Thus, it can be rotated by flicking a finger, thereby rotating the output shaft 242.

[0057] More preferably, such as Figure 3 and Figure 6 As shown, the bottom of the lifting seat 3 is provided with a cavity 31, and the lifting seat 3 includes a surrounding plate 32 located around the cavity 31; at least a portion of the outer shell 12 is always located within the cavity 31.

[0058] The lifting seat 3 is installed on the top of the outer shell 12. During the lifting process of the lifting seat 3, the surrounding plate 32 blocks the gap between the lifting seat 3 and the side of the outer shell 12, preventing foreign objects from easily entering the first transmission cavity 1a. The aforementioned foreign objects mainly refer to some large objects that have a significant impact on the stability of the lifting mechanism 2, and do not refer to dust. Of course, the structure of this embodiment also has a certain blocking effect on dust, and can at least slow down the rate at which dust accumulates in the first transmission cavity 1a to a certain extent.

[0059] In some embodiments, such as Figure 4 As shown, the top of the base 11 is recessed with a first groove 113, and at least a portion of the guide seat 21 is embedded in the first groove 113. The guide seat 21 and the base 11 are locked together by screws.

[0060] In this embodiment, the installation stability of the guide seat 21 can be improved by the cooperation between the first groove 113 and the bottom of the guide seat 21, thereby improving the transmission stability between the guide seat 21, the screw 22 and the lifting body 23.

[0061] In some embodiments, such as Figure 5 As shown, the top of the base 11 is provided with a second recess 114; the outer shell 12 includes a cylindrical shell 12a and a plug 12b fixedly connected to the cylindrical shell 12a. A portion of the plug 12b protrudes downward from the cylindrical shell 12a and is inserted into the second recess 114. The plug 12b is locked and fixed to the base 11 by screws; the lower edge of the cylindrical shell 12a abuts against the top of the base 11.

[0062] In this embodiment, by providing the second recess 114 and the insert 12b, the housing 12 can be quickly installed on the base 11. When the screws between the base 11 and the insert 12b are tightened, the lower edge of the cylindrical housing 12a can be locked to the top of the base 11. Naturally, the shape of the second recess 114 is adapted to the insert 12b, so that the insert 12b can only slide up and down in the second recess 114.

[0063] Specifically, to facilitate the wiring of the dual-head motor 24, the above solution is as follows: Figure 1 and Figure 5 As shown, the outer casing 12 is provided with a wire hole 122. In this way, the wire can be passed through the wire hole 122 to connect to the dual-head motor 24.

[0064] In some embodiments, such as Figure 4 As shown, the guide seat 21 is provided with a first sensor 212 and a second sensor 213, which are arranged vertically at intervals; the lifting body 23 is provided with a detection component for sensing by the first sensor 212 and the second sensor 213.

[0065] In this embodiment, the detection and positioning of the height position of the lifting seat 3 can be achieved by sensing the detected object through the first sensor 212 and the second sensor 213. For example, it can be set so that when the first sensor 212 senses the detected object, it indicates that the lifting seat 3 has risen to the highest position; and when the second sensor 213 senses the detected object, it indicates that the lifting seat 3 has descended to the lowest position.

[0066] In some embodiments, such as Figure 1 and Figure 4 As shown, the base 11 is provided with mounting holes 115. The base 11 can be fixed to an optical experimental platform (e.g., a breadboard) through the mounting holes 115, thereby fixing the position of the lifting seat on the optical experimental platform.

[0067] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0068] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
