Description

Technical Field

[0001] This invention belongs to the field of atomic clock technology, specifically a glass collimation device for a cesium clock. Background Technology

[0002] Atomic clocks are indispensable key equipment in the fields of timekeeping and time transmission in various countries. The main types include cesium clocks, rubidium clocks, and hydrogen clocks. Among them, cesium clocks occupy a central position in the field of frequency reference due to their excellent long-term stability, high accuracy, good start-up repeatability, and "zero drift" characteristics. For example, products such as the BD1024 cesium atomic clock are widely used in high-precision frequency standards and time synchronization. These characteristics make them irreplaceable in high-end fields such as time and frequency transmission, measurement, and satellite navigation.

[0003] Currently, various methods have been proposed for a glass collimation device for cesium clocks in the prior art. For example, a patent application with publication number "CN212342299U" discloses a glass collimator for cesium clocks, which includes: a collimating plate, a first collimating block, a second collimating block, a third collimating block, and a fixing plug with a hollow structure. The collimating plate is provided with a notch and a first groove and a second groove formed on the surface of the notch. The first groove and the second groove are perpendicular to each other, and a first opening is also provided through the first groove. The first collimating block and the second collimating block are fixed to both sides of the collimating plate by brazing. However, brazing requires precise control of temperature, atmosphere, and placement of filling material, which requires specialized equipment and skilled operators, increasing the complexity and cost of the process.

[0004] Therefore, this utility model provides a glass collimation device for cesium clocks. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The glass collimation device for a cesium clock of this utility model includes a first collimation plate and a second collimation plate. The side wall of the first collimation plate has two fixing grooves. The side walls of the first collimation plate and the second collimation plate each have a second groove. The side wall of the second groove has a first groove. The side wall of the second collimation plate is fixedly connected to two fixing blocks. The fixing blocks are provided with threaded holes. The side wall of the first collimation plate is threadedly connected to a threaded rod. The threaded rod passes through the fixing groove and corresponds to the threaded hole. The end of the threaded rod away from the first collimation plate is fixedly connected to an internal hexagonal knob. A third collimation plate is placed in the second groove. The side wall of the third collimation plate has a first opening. An adjustment mechanism for adjusting the size of the first opening is installed in the first opening.

[0007] Preferably, the third collimating plate has a third groove on its side wall, multiple collimating channels are provided inside the third collimating plate, a hollow fixing plate is placed inside the third groove, and a second opening is provided on the side wall of the hollow fixing plate.

[0008] Preferably, one end of the hollow fixing plate is located in the first groove, and the depth of the two first grooves plus the depth of the third groove is the same as the height of the hollow fixing plate.

[0009] Preferably, the two fixing slots are located at diagonal positions on the side wall of the first alignment plate, and the fixing block corresponds to the fixing slot.

[0010] Preferably, the adjustment mechanism includes a baffle, and a groove is provided on the side wall of the first opening. The baffle slides in the groove, and a moving mechanism for moving the baffle is installed in the groove.

[0011] Preferably, the moving mechanism includes a knob and a screw, the screw being rotatably mounted on the side wall of the baffle, the screw being threadedly connected to the side wall of the slide groove, and the knob being fixedly mounted on the end of the screw away from the baffle.

[0012] Preferably, the fixing block is not flush with the side wall of the second collimating plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The glass collimation device for a cesium clock described in this utility model involves attaching a first collimating plate and a second collimating plate together, allowing a fixing block to be inserted into a fixing groove, thus completing a preliminary and quick connection between the first and second collimating plates. Subsequently, using a hex wrench to rotate an internal hexagonal knob causes the knob to rotate a threaded rod. During rotation, the threaded rod engages with a threaded hole on the fixing block, thereby fixing the fixing block in the fixing groove. This completes the rapid installation of the first and second collimating plates, requiring no complex equipment or processes, and is simple and easy to operate, greatly improving installation efficiency. Furthermore, the installation method requires a low level of technical skill from the operator, reducing training costs and operational difficulty.

[0015] 2. The glass collimation device for a cesium clock described in this utility model can be rotated by turning a knob, which in turn causes a baffle to slide within a groove. The baffle blocks the opening size of the screw, thereby adjusting the opening size and controlling the intensity of the cesium atomic beam entering the device. A larger opening allows more atoms to enter, potentially increasing signal strength; a smaller opening reduces the number of atoms. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a glass collimation device for a cesium clock includes a first collimating plate 1 and a second collimating plate 2. The first collimating plate 1 has two fixing grooves 8 on its side wall, and both the first and second collimating plates 1 and 2 have second grooves 10 on their side walls. The second grooves 10 have first grooves 9 on their side walls. Two fixing blocks 11 are fixedly connected to the side wall of the second collimating plate 2. Each fixing block 11 has a threaded hole. A threaded rod 4 is threadedly connected to the side wall of the first collimating plate 1, passing through the fixing grooves 8 and corresponding to the threaded holes. An internal hexagonal knob 3 is fixedly connected to the end of the threaded rod 4 away from the first collimating plate 1. A third collimating plate 5 is placed in the second groove 10. The side wall of the third collimating plate 5 has a first opening 6, and an adjustment mechanism for adjusting the size of the first opening 6 is installed in the first opening 6. During operation, by fitting the first collimating plate 1 and the second collimating plate 2 together, the fixing blocks 11 are inserted into the fixing grooves 8, completing the initial quick connection of the collimating plates. Subsequently, by turning the internal hexagonal knob 3 with a hex wrench, the threaded rod 4 is rotated. During the rotation, the threaded rod 4 engages with the threaded hole on the fixing block 11, fixing the fixing block 11 in the fixing groove 8, thereby completing the quick installation of the alignment plate.

[0026] like Figure 5 As shown, the third collimating plate 5 has a third groove 14 on its side wall, and multiple collimating channels are provided inside the third collimating plate 5. A hollow fixing plate 13 is placed inside the third groove 14, and a second opening 12 is provided on the side wall of the hollow fixing plate 13. During operation, cesium atoms enter the device through the first opening 6 and pass through the multiple collimating channels on the third collimating plate 5. The design of these collimating channels ensures that only cesium atoms moving in a specific direction can pass through, while atoms deviating from the direction are filtered out.

[0027] like Figure 4 As shown, one end of the hollow fixing plate 13 is located within the first groove 9, and the depth of the two first grooves 9 plus the depth of the third groove 14 is the same as the height of the hollow fixing plate 13. With this structure, the left and right sides of the hollow fixing plate 13 are located within the third alignment plate 5, while the front and rear sides of the hollow fixing plate 13 are located within the first groove 9. The hollow fixing plate 13 can be used to fix the third alignment plate 5 between the first alignment plate 1 and the second alignment plate 2, achieving the effect of quick installation of the third alignment plate 5 between the first alignment plate 1 and the second alignment plate 2.

[0028] like Figure 2 and Figure 3As shown, the two fixing slots 8 are located diagonally opposite each other on the side wall of the first alignment plate 1, and the fixing block 11 corresponds to the fixing slots 8. Through the above structure, the diagonally opposite fixing slots 8 and fixing blocks 11 can distribute the force, improve the structural stability of the first alignment plate 1 and the second alignment plate 2, and reduce deformation or damage caused by single-point force.

[0029] like Figure 1 and Figure 5 As shown, the adjustment mechanism includes a baffle 16, and a groove 17 is provided on the side wall of the first opening 6. The baffle 16 slides within the groove 17, and a moving mechanism for moving the baffle 16 is installed within the groove 17. Through this structure, the opening size can be precisely adjusted by sliding the baffle 16 within the groove 17, meeting the precise requirements of different experiments or applications for atomic beam intensity and divergence angle.

[0030] like Figure 5 As shown, the moving mechanism includes a knob 7 and a screw 15. The screw 15 is rotatably mounted on the side wall of the baffle 16 and is threadedly connected to the side wall of the slide groove 17. The knob 7 is fixedly mounted on the end of the screw 15 away from the baffle 16. During operation, rotating the knob 7 causes the screw 15 to rotate, thereby causing the baffle 16 to slide within the slide groove 17. With this structure, the movement of the baffle 16 can be achieved simply by rotating the knob 7. The operation is simple, easy to learn, and allows for quick adjustment, saving time and effort.

[0031] like Figure 3 As shown, the fixing block 11 is not flush with the side wall of the second alignment plate 2. With this structure, even if the threaded rod 4 does not enter the threaded hole in the fixing block 11, the threaded rod 4 is still threaded onto the second alignment plate 2 using the distance between the fixing block 11 and the side wall of the second alignment plate 2, making it less likely for the threaded rod 4 to be lost. When it is necessary to insert the threaded rod 4 into the threaded hole on the fixing block 11, simply turn the internal hexagonal knob 3.

[0032] Working principle: By fitting the first alignment plate 1 and the second alignment plate 2 together, the fixing block 11 is inserted into the fixing groove 8, completing the initial quick connection of the alignment plate. Subsequently, by turning the internal hexagonal knob 3 with a hex wrench, the threaded rod 4 is driven to rotate. During the rotation, the threaded rod 4 engages with the threaded hole on the fixing block 11, fixing the fixing block 11 in the fixing groove 8, thereby completing the quick installation of the alignment plate.

[0033] To adjust the size of the first opening 6, the screw 15 is rotated by turning the knob 7, which in turn causes the baffle 16 to slide within the groove 17. The movement of the baffle 16 obstructs the opening size of the screw 15, thereby achieving the effect of adjusting the opening size. This design allows the device to flexibly adjust the opening size according to different experimental needs, optimizing the intensity and divergence angle of the atomic beam.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
