Description

Technical Field

[0001] This utility model relates to the field of teaching supplies, and more particularly to a teaching light fixture. Background Technology

[0002] An optical bench provides a relatively stable platform for optical experiments, ensuring the transparency and measurability of the optical path. It is typically available in single-rail and double-rail types. Aside from the number of rails, the two types of optical benches are essentially the same in terms of their operating characteristics and testing modes.

[0003] A single-rail optical bench typically consists of a guide rail and slides. The guide rail is horizontally positioned above two supports, and a number of slides are movably mounted on the guide rail. Each slide has a clamping rod with a test element on its upper side. Compared to a double-rail optical bench, the single-rail optical bench has a simpler structure, lower manufacturing cost, and faster guide rail assembly. However, the installation and disassembly of the slides are more complicated and time-consuming. This is because gaps can easily appear between the upper and lower parts of the slides, leading to rolling, slippage, and rail jamming due to inadequate screw fixing.

[0004] Therefore, the upper and lower parts of the slide must be aligned and pressed together before being tightened by four screws. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a teaching optical bench, which achieves the overall stability of the slide by sliding connection between the clamp and the guide rail, providing a good working environment for the test element. It has a novel design, simple operation, convenient installation, stable performance, and high work efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: including a guide rail and a bracket, wherein the guide rail 1 and the bracket are preferably made of alloy material and have a light-colored coating on the outside to enhance the aesthetics.

[0007] A guide groove is provided along the upper side of one end of the guide rail to the upper side of the other end. The guide groove passes through the outer sides of both ends of the guide rail. Scale markings are provided on the lower part of both sides of the guide rail. Interfaces are provided on the lower side of both ends of the guide rail.

[0008] Both brackets are detachably mounted on the lower side of one end of the guide rail. Each bracket includes a support rod and a base plate. Both support rods have a joint on their upper side and a circular base plate on their lower side.

[0009] A certain number of slide blocks are movably mounted on the guide rail, and the slide blocks are slidably connected to the guide rail.

[0010] The slide includes a slide body and a slider. Each slide body has a screw-in port with internal threads on its upper side and a clamping opening on its lower side. Each clamping opening has a slider in the middle section on its upper side.

[0011] The beneficial technical effects of this utility model are: the sliding connection between the clamp and the guide rail achieves the overall stability of the slide, providing a good working environment for the test components. It has a novel design, is easy to operate, has stable performance, and high work efficiency. The sliding connection between the slider and the guide groove further improves the stability of the slide during operation, ensuring the smooth progress of optical testing. It is easy to install, runs smoothly, moves flexibly, and has obvious effects. Attached Figure Description

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] It should be noted that the terms "upper side", "lower side", "upper part", "lower part", "outer side", "inner side", "one end", "the other end", "one side", "the other side", "upper", "inner", "center", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0020] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "assembly," "equipped with," "set up," "located in," "into," "fixed," "connected," "linked," and "joined" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms based on the specific circumstances.

[0021] Please refer to Figure 1 The guide rail 1 is made of a preferred alloy material and has a light-colored coating on the outside to enhance its aesthetics.

[0022] Guide rail 1 structure: The length of guide rail 1 needs to be determined according to the actual needs of the user, and the width and thickness are 5cm and 4cm respectively. Guide rail 1 is mainly used to provide a good sliding platform or path for slide 7.

[0023] A rectangular guide groove 2 is formed along the upper middle section of one end of the guide rail 1 to the upper middle section of the other end. The depth of the guide groove 2 is half the thickness of the guide rail 1. The guide groove 2 mainly serves to limit the sliding motion. It improves the stability of the slide block 7 during operation by engaging with the slider 10 in a locking manner, so that it always moves along the guide groove 2.

[0024] The guide rail 1 has easily identifiable scale markings 5 ​​on both lower sides. The scale markings 5 ​​are used to measure the object distance and image distance during imaging, ensuring the accuracy of optical testing.

[0025] The scale markings 5, also known as measuring lines or rulers, are each engraved on the lower part of both sides of the guide rail 1 by specialized instruments or tools, without causing any resistance to the operation of the slide block 7. Furthermore, each scale marking has a dark-colored coating, allowing the user to quickly visually estimate the measurement values ​​after the scale markings 5 ​​are coated with a dark color.

[0026] The guide rail 1 has square interfaces 3 on both lower ends, which can only accommodate the connectors 6. The interfaces 3 are the main connection ports between the guide rail 1 and the bracket 4, and can be quickly assembled and disassembled by movably connecting with the connectors 6.

[0027] Structure of bracket 4: The height of bracket 4 should be determined according to the application. Since the two brackets 4 have the same structure and specifications, this embodiment only describes one as an example.

[0028] The bracket 4 consists of cylindrical support rods and circular base plates. Each support rod has a square connector 6 on its upper side that fits into the inner cavity of the interface 3. The lower sides of the two support rods are welded and fixed to the center of the upper side of the two base plates. The main function of the bracket 4 is to support and lift the guide rail 1, allowing optical testing to be performed at a certain height.

[0029] Please refer to Figure 2 The connectors 6 on the upper part of the two brackets 4 are respectively movably inserted into the interface 3 on the lower side of one end of the guide rail 1. In fact, when both connectors 6 are inserted to their limit, the guide rail 1 is in a horizontal state.

[0030] Installation procedure for bracket 4: First, insert one connector 6 into the interface 3 on the lower side of one end of the guide rail 1, then press down on one end of the guide rail 1 by hand to ensure that the connector 6 is completely inside the interface 3. Insert the other connector 6 into the interface 3 on the lower side of the other end of the guide rail 1, and return the guide rail 1 to a horizontal position.

[0031] Since connector 6 is movably inserted into interface 3, bracket 4 can be freely removed and stored separately.

[0032] Since both connector 6 and interface 3 adopt a square structure, after the square connector 6 and interface 3 are fitted together, there will be no rotation or slippage, so that the optical bench will always remain horizontal and stable.

[0033] Please refer to Figure 3 A certain number of slide blocks 7 are movably mounted on the guide rail 1, and the slide blocks 7 are slidably connected to the guide rail 1. The slide blocks 7 are mainly used to install test elements and facilitate the adjustment of the position of optical elements.

[0034] After the slide block 7 is installed, its lower sides are level with or the same as the lower side of the guide rail 1.

[0035] Since the scale mark 5 is engraved by special equipment and then polished smooth by sandpaper, it does not affect the sliding of the slide block 7 at all.

[0036] Please refer to Figure 4 Since the specifications and structure of each slide 7 are the same, this embodiment will only take one as an example for detailed description in order to better understand the performance advantages of the slide 7.

[0037] The slide block 7 has a cuboid structure and is preferably made of an alloy material with good surface smoothness. Its actual length, width and thickness are 15cm, 7.2cm and 5.2cm, respectively.

[0038] The slide block 7 has a coating on the outside that is the same color as the outside of the guide rail 1 to enhance its aesthetics.

[0039] The slide block 7 includes a slide block body 8 and a slider 10. The upper side of the slide block body 8 is provided with a circular screw-in port 9 that matches the diameter of the lower part of the clamping rod 12. The inner wall of the screw-in port 9 is threaded. The screw-in port 9 is the main connecting part on the slide block 7, which stabilizes the optical element by screwing it into the lower part of the clamping rod 12.

[0040] The screw inlet 9 extends downwards into the corresponding slider 10, but does not penetrate the lower side of the slider 10.

[0041] The slide body 8 has a clamp 11 on its lower side that matches the width of the guide rail 1, and the depth of both sides of the clamp 11 is equal to the thickness of the guide rail 1. The main function of the clamp 11 is to clamp or fit around a section of the guide rail 1, so that the slide 7 always works in a stable or horizontal state.

[0042] A rectangular slider 10 is longitudinally integrated into the upper central section of the clamp 11. The width and thickness of the slider 10 are equal to the width and depth of the guide groove 2. The slider 10 assists in sliding and ensures the stability of the slide block 7 during operation by slidingly connecting with the guide groove 2, thus providing a suitable testing environment or distance for the optical components.

[0043] Installation procedure for slide block 7: After lifting slide block 7 horizontally in the longitudinal direction, it is then fitted onto the upper side and both sides of the corresponding guide rail 1. After the clamp 11 fits onto part of the guide rail 1, the slider 10 is horizontally fitted and locked into the guide groove 2.

[0044] There is no form of fixation or connection between the slide 7 and the guide rail 1, and it can slide freely on the guide rail 1.

[0045] The biggest technical advantage of slide block 7 is that: firstly, the lower clamp 11 is connected to a section of the guide rail 1 to achieve overall stability; secondly, the slider 10 and the guide groove 2 are connected in a snap-fit ​​manner to further improve the stability during sliding and ensure the smooth progress of optical testing.

[0046] The biggest technical advantage of slide 7 II: It can be quickly installed by sliding it down onto a section of guide rail 1, and can be quickly disassembled by lifting it up to separate it from guide rail 1.

[0047] Since both the guide rail 1 and the slide 7 are made of a superior alloy material with a smooth surface, they provide a certain degree of auxiliary sliding effect. Therefore, there is no problem for the slide 7 to slide flexibly on the guide rail 1.

[0048] Please refer to Figure 5 An optical bench is a platform that provides optical testing, which can fully ensure the transparency and measurability of the optical path; test elements are used to measure or detect the distance between the object and the image.

[0049] It should be noted that the test components are not within the technical scope of this application.

[0050] This embodiment only symbolically provides a few test elements such as light source 13, convex lens 14, and imaging plate 15. The purpose of providing test elements is to better understand the performance advantages and functions of slide 7.

[0051] The light source 13, the convex lens 14 and the imaging plate 15 are all fixedly provided with cylindrical clamping rods 12 on their lower sides, and each clamping rod 12 has a screw on its lower outer circle that matches the thread on the inner wall of the screw inlet 9.

[0052] The clamping rod 12 has the function of flexibly adjusting the height. The clamping rod 12 consists of a telescopic rod and a sleeve. The lower part of each telescopic rod is movably inserted into the upper cavity of a sleeve, and then tightened and fixed from one side by a screw.

[0053] Optical component installation steps: 1. According to the position of each component, screw the clamping rod 12 at the bottom of the light source 13, convex lens 14 and imaging plate 15 into the screw hole 9 on the upper side of a slide block 7 respectively; 2. Move each component to a suitable test position as required; 3. Adjust the light source 13, convex lens 14 and imaging plate 15 to a suitable test height respectively, so that their midpoints are relative to each other; 4. Start the optical experiment.

[0054] Real-time height adjustment steps: 1. Loosen the screws on one side of each sleeve in sequence so that each telescopic rod can be pulled up and down; 2. Adjust the height of the light source 13, convex lens 14 and imaging plate 15 uniformly; 3. After the height is adjusted, tighten the screws on one side of each sleeve in sequence to fix it.

[0055] As can be seen from the figure, each screw is movably screwed into the fixed screw hole on one side of the sleeve.

[0056] In actual operation, when a new test element needs to be added, the operator needs to remove the unused element from slide 7 and replace it with the element to be used.

[0057] Real-time component replacement steps: 1. Unscrew the clamping rod 12 at the bottom of the unused component from the corresponding screw-in port 9; 2. Screw the clamping rod 12 at the bottom of the new component (the component to be used) into the screw-in port 9 on the upper side of the corresponding slide 7; 3. After adjusting the component height, perform relevant tests.

[0058] In fact, without the guide rail 1 flipping, the slide 7 can maintain a tight and active connection with the guide rail 1, without problems such as tipping, jamming, loosening, or displacement. The overall performance is excellent and safe and reliable.

[0059] The greatest technical advantage of this utility model optical bench is that the slide 7 can be quickly installed or assembled by wrapping a portion of the guide rail 1 downwards, and the slide 7 can be quickly disassembled or separated from the guide rail 1 by lifting it upwards.

[0060] The optical bench of this utility model can solve the problem of excessive time consumption in the installation and disassembly of the slide block 7. It has a novel design, simple operation, stable operation, and obvious effect. The guide groove 2 and the slider 10 are connected in a matching sliding connection so that the slide block 7 always maintains a horizontal and stable state. It is simple to manufacture, quick to install, stable in performance, and safe and reliable.
