Description

Technical Field

[0001] The utility model relates to the technical field of optical benches, in particular to a single-rod optical bench. Background Art

[0002] Optical testing experiment is one of the compulsory courses in middle school physics, and the optical bench is a multifunctional general optical instrument. The optical bench mainly used for testing is equipped with independent components such as parallel light tube, autocollimation telescope, measuring microscope and clamp on the guide rail seat, which can be arranged and adjusted as needed to carry out multiple testing tasks.

[0003] The optical bench is also called the optical instrument bench. It is usually composed of a base (including two side seats), a guide rail (double guide rail) and a slide. The two guide rails are inserted in parallel on the two side seats, and a certain number of slides are movably provided on the two guide rails. A clamping rod with a test element is provided on the upper side of each slide.

[0004] However, the shortcomings of the existing optical fixture are:

[0005] First, the movement stability of the slide on the double guide rails is poor. In actual use, the slide slides on the double guide rails for a long time, and the double guide rails are easy to loosen, causing the slide to get stuck on the guide rails. The movement is unchanged and the use effect is poor. In addition, due to the looseness of the double guide rails, the position of the slide will also change, affecting the test effect.

[0006] Second, the two ends of the guide rail often withdraw from the insertion cavity of the side seat. The reason is that the two ends of the guide rail are not fixed in any form, resulting in an unstable connection of the guide rail. Summary of the invention

[0007] The main purpose of the utility model is to overcome the deficiencies in the prior art and provide a single-rod optical fixture.

[0008] The technical solution adopted by the utility model to achieve its technical purpose is: a single-rod optical fixture, including a base, wherein the base includes a side seat A and a side seat B, and the height of the base needs to be determined according to the size of the optical fixture model.

[0009] One side of the inner part of the side seat A and the side seat B is a hollow structure, and a connecting hole is opened in the middle of the upper end of the other side;

[0011] It should be pointed out that the structures and specifications of the side seat A and the side seat B are the same, and the connecting holes are connected to the inside of the corresponding insertion cavity.

[0012] A hollow guide rail is provided between the side seat A and the side seat B. The length of the guide rail depends on the size of the optical bench model. The guide rail is set as a tubular structure, and a groove is formed by inward depression on one side thereof;

[0013] Plug heads matching the insertion cavity plates are provided at both ends of the guide rail. After the plug heads at both ends of the guide rail are inserted into the insertion cavity plates on the side seat A and the side seat B, they are fixed by interference fit;

[0014] By providing the cooperation of the plug heads and the insertion cavity plates on the outer sides of both ends of the guide rail, firstly, the guide rail can be flexibly disassembled and assembled with the two side seats, which is beneficial to the storage and carrying of the optical bench; secondly, the plug heads can be effectively fixed, which is beneficial to the stability of the guide rail, and other types of guide rails can also be freely replaced, such as guide rails with different lengths.

[0015] A plurality of sliding seats are slidably connected to the guide rail. Among the plurality of sliding seats on the guide rail, a distance is maintained between every two adjacent sliding seats; the inside of the sliding seat is hollow, and pipe cavities matching the guide rail are provided on both sides thereof;

[0016] Through the cooperation of the groove and the pipe cavity, the movement of the sliding seat becomes more flexible, the practical problem that the movement of the sliding seat is slow due to cold shrinkage is solved, and the sliding seat can be quickly installed on the corresponding guide rail. The whole installation process is convenient, fast, time-saving and labor-saving.

[0017] Preferably, a straight cavity with internal threads is fixedly connected above the sliding seat, and a clamping rod is threadedly connected inside the straight cavity, so that the clamping rod is fixed inside the straight cavity;

[0018] The straight cavity is of a cylindrical structure, and the lower port of the straight cavity is communicated with the inside of the sliding seat. For the straight cavity on the sliding seat, firstly, the lower part of the clamping rod can move in, which is beneficial to the flexible replacement of relevant test components; secondly, it is beneficial to the flexible adjustment of the height of the clamping rod.

[0019] Preferably, the maximum adjustment limit of the height of the clamping rod is 5 cm.

[0020] Preferably, each sliding seat on the guide rail carries an independent test component, and a light source, a convex lens and an imaging screen are respectively fixedly installed at the upper end of the clamping rod. The masses of these test components are relatively light and will not exert too much pressure on the sliding seat.

[0021] Preferably, a scale is provided on one side of the top ends of the side seat A and the side seat B. Card holes are provided at both ends of the scale, and the card holes are clamped on two semi-circular clamping blocks integrally connected to the top ends of the side seat A and the side seat B.

[0022] Compared with the prior art, the beneficial effects of the present utility model are:

[0023] This single-rod optical bench, through the setting of a single guide rail, is conducive to the performance of the guide rail and solves the practical problem of instability during the operation of a double guide rail.

[0032] Please refer to Figures 1-3 , a single-rod optical bench, including a base. The base includes side seat A1 and side seat B4, and the height of the base needs to be determined according to the model size of the optical bench.

[0033] One side inside of side seat A1 and side seat B4 is a cavity structure, and a connection hole 2 is provided at the center of the upper end of the other side; an insertion cavity plate 5 is fixedly connected inside the cavities of side seat A1 and side seat B4. One side of the insertion cavity plate 5 is communicated with the connection hole 2, and the other side does not penetrate.

[0034] It should be noted that the structures and specifications of side seat A1 and side seat B4 are the same, and the connection holes 2 are all internally connected to the corresponding insertion cavities 5.

[0035] A hollow guide rail 3 is provided between side seat A1 and side seat B4. The length of the guide rail 3 needs to be determined according to the model size of the optical bench. The guide rail 3 is set as a tubular structure, and a groove is formed by inward depression on one side; plugs 6 matching the insertion cavity plates 5 are provided at both ends of the guide rail 3. After the plugs 6 at both ends of the guide rail 3 are inserted into the insertion cavity plates 5 on side seat A1 and side seat B4, they are fixed by interference fit; through the cooperation of the plugs 6 provided on the outer sides of both ends of the guide rail 3 and the insertion cavity plates 5, first, the guide rail 3 can be flexibly disassembled and assembled with the two side seats, which is beneficial to the storage and carrying of the optical bench; second, the plugs 6 can be effectively fixed, which is beneficial to the stability of the guide rail 3, and other types of guide rails 3 can also be freely replaced, such as guide rails 3 with different lengths.

[0036] A plurality of sliding seats 7 are slidably connected to the guide rail 3. For the plurality of sliding seats 7 on the guide rail 3, a distance is maintained between every two adjacent sliding seats 7; the inside of the sliding seat 7 is hollow, and pipe cavities 9 matching the guide rail 3 are provided on both sides; through the cooperation of the groove and the pipe cavity 9, the movement of the sliding seat 7 becomes more flexible, solving the actual problem that the movement of the sliding seat 7 is slow due to the influence of cold shrinkage, and the sliding seat 7 can be quickly installed on the corresponding guide rail 3 at the corresponding place. The entire installation process is convenient, fast, time-saving, and labor-saving.

[0037] It should be noted that the sliding seat 7 is made of high-quality silica gel. The sliding seat 7 made of silica gel material is not only environmentally friendly and wear-resistant, but also has the advantages of resisting high and low temperatures, not being easily deformed, being insulated, and having a stable state. Due to the very stable molecular structure of silica gel, the groove at the lower part of the pipe cavity 9 will not expand and deform due to the influence of thermal expansion, nor will it shrink due to the influence of cold shrinkage.

A clamping rod 12 is threadedly connected inside the straight cavity 8, so that the clamping rod 12 is fixed in the straight cavity 8. The straight cavity 8 is of a cylindrical structure. The lower port of the straight cavity 8 communicates with the inside of the sliding seat 7. For the straight cavity 8 on the sliding seat 7, on the one hand, the lower part of the clamping rod 12 can move in, which is conducive to the flexible replacement of relevant test components, and on the other hand, it is conducive to the flexible adjustment of the height of the clamping rod 12. The maximum adjustment limit of the height of the clamping rod 12 is 5 cm.

[0039] Each sliding seat 7 on the guide rail 3 carries an independent test component. A light source 10, a convex lens 11 and an imaging screen 13 are respectively fixedly installed at the upper end of the clamping rod 12. The masses of these test components are relatively light and will not exert too much pressure on the sliding seat 7.

[0040] Furthermore, in this embodiment, a scale is provided on one side of the top ends of the side seat A1 and the side seat B4. Card holes are provided at both ends of the scale, and the card holes are stuck on two semi-circular clamping blocks integrally connected to the top ends of the side seat A1 and the side seat B4.

[0041] Specifically, during use, one end of the guide rail 3 passes through the internal lumen 9 of each sliding seat 7 in sequence, and then the sliding seats 7 are evenly distributed, and then the plugs 6 at both ends of the guide rail 3 are fixed in the insertion cavity 5.

[0042] According to the position of each component, the clamping rods 12 at the lower parts of the light source 10, the convex lens 11 and the imaging screen 13 are respectively screwed into the straight cavity 8 on the upper side of a sliding seat 7. Each component is moved to the required position as required, and then the fronts of the light source 10, the convex lens 11 and the imaging screen 13 are adjusted.

[0043] During actual operation, when a new experimental test component needs to be added, the operator needs to remove the unused component on the sliding seat 7 and replace it with the component to be used.
