Description

Technical Field

[0001] This utility model relates to the field of quartz crystal resonator technology, specifically a quartz crystal resonator with stable pin connections. Background Technology

[0002] A quartz crystal resonator, also known simply as a quartz crystal or crystal oscillator, is an electronic component that uses the piezoelectric effect of quartz crystals to generate high-precision oscillation frequencies. The following is a detailed introduction to quartz crystal resonators, including their basic principles, structure, characteristics, applications, and development trends.

[0003] Utility model patent application document with publication number "CN221127255U" discloses a quartz crystal resonator with stable pin connection, including a base, two pins passing through and fixedly connected within the base, a quartz crystal at the top of each pin, a limiting groove at the top of the base, a sealing ring fixedly connected to the inner edge of the limiting groove, a shell within the limiting groove, support columns on both sides of the quartz crystal, a fixing seat fixedly connected to the top of each support column, a fixing groove at the top of each fixing seat, and a fixing component within each fixing groove. In this utility model, the bidirectional threaded rod, rotating column, moving seat, first support arm, second support arm, lifting plate, connecting block, second rotating shaft, and sealing ring work together to compress the shell, facilitating disassembly, and the sealing ring enhances airtightness, thereby improving reliability.

[0004] The pin-connected quartz crystal resonator disclosed in the above document has the following drawbacks: the position of the limiting mechanism for the quartz crystal is fixed, making it difficult to adapt to quartz crystals of different sizes, which results in relatively poor flexibility in use.

[0005] Therefore, it can be seen that the existing pin-connected quartz crystal resonators do not have a limiting mechanism that can adapt to different sizes. It is necessary to improve the existing shortcomings and provide a pin-connected quartz crystal resonator. Utility Model Content

[0006] The purpose of this invention is to provide a quartz crystal resonator with stable pin connections, which solves the problem that the position of the limiting mechanism for quartz crystals in the prior art is fixed, making it difficult to adapt to quartz crystals of different sizes, thus resulting in relatively low flexibility in use.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a quartz crystal resonator with stable pin connections, comprising a base, a plurality of pins fixedly mounted on the lower surface of the base, a limiting groove formed on the upper surface of the base, a sealing gasket installed inside the limiting groove, a housing placed inside the limiting groove, the housing and the sealing gasket abutting against each other, an adjustment mechanism installed inside the base, a fixing mechanism installed at both ends of the adjustment mechanism, a bracket fixedly mounted on the upper surface of the base, an electric push rod fixedly mounted on the upper surface of the bracket, the output end of the electric push rod extending to the lower surface of the bracket, a pressure plate fixedly mounted on the output end of the electric push rod, the pressure plate and the bracket being slidably connected, the lower surface of the pressure plate abutting against the upper surface of the housing.

[0009] Furthermore, the adjustment mechanism includes a bidirectional screw and a turbine, with the bidirectional screw rotatably connected inside the base, and the turbine fixedly installed in the middle of the outer surface of the bidirectional screw.

[0010] Furthermore, a rotating rod is rotatably connected inside the base, and a worm gear is fixedly installed on the outer surface of one end of the rotating rod. The worm gear and the turbine are meshed and connected. One end of the rotating rod extends to the outer surface of the base, and a handle is fixedly installed on one end of the rotating rod.

[0011] Furthermore, the bidirectional screw has movable plates threadedly connected to both its positive and negative threads, and both sets of movable plates are slidably connected to the interior of the base.

[0012] Furthermore, the fixing mechanism includes a fixing plate, and a fixing plate is fixedly installed on one end of each of the movable plates, and a limit screw is threadedly connected inside each fixing plate.

[0013] Furthermore, a limit plate is fixedly installed at one end of each of the limiting screws.

[0014] This utility model has the following beneficial effects:

[0015] (1) When it is necessary to place quartz crystals of different sizes, the handle is turned and the handle drives the rotating rod to rotate. Since the worm at one end of the rotating rod is meshed with the turbine on the bidirectional screw, the rotation of the rotating rod will cause the bidirectional screw to rotate. The moving plate on the positive and negative threads of the bidirectional screw will move in opposite directions when the bidirectional screw rotates. Because the moving plate is slidably connected to the base, its rotational freedom is restricted, thereby ensuring that the moving plate can only move along the axial direction of the bidirectional screw, so as to limit and fix quartz crystals of different sizes and improve the flexibility of use.

[0016] (2) This utility model works by an electric push rod. The output end of the electric push rod pushes the pressure plate downward. Since the pressure plate is slidably connected to the inside of the bracket, the pressure plate can only move downward in the vertical direction. The lower surface of the pressure plate abuts against the upper surface of the shell, thereby applying pressure to the shell in the vertical direction and fixing the shell tightly to the base. The lower surface of the shell abuts against the sealing gasket, ensuring the sealing effect and avoiding the need for manual driving of the limiting mechanism to fix the shell in the prior art, thus improving the ease of use.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 As shown, this utility model is a quartz crystal resonator with stable pin connection, including a base 1. Several sets of pins 2 are fixedly installed on the lower surface of the base 1. A limiting groove 101 is opened on the upper surface of the base 1. A sealing gasket 102 is installed inside the limiting groove 101. A housing 8 is placed inside the limiting groove 101. The housing 8 and the sealing gasket 102 abut against each other. An adjustment mechanism 3 is installed inside the base 1. A fixing mechanism 4 is installed on both ends of the adjustment mechanism 3. A bracket 5 is fixedly installed on the upper surface of the base 1. An electric push rod 6 is fixedly installed on the upper surface of the bracket 5. The output end of the electric push rod 6 extends to the lower surface of the bracket 5. A pressure plate 7 is fixedly installed on the output end of the electric push rod 6. The pressure plate 7 and the bracket 5 are slidably connected. The lower surface of the pressure plate 7 abuts against the upper surface of the housing 8.

[0027] When the electric push rod 6 is working, the output end of the electric push rod 6 pushes the pressure plate 7 downward. Since the pressure plate 7 is slidably connected to the bracket 5, the pressure plate 7 can only move downward in the vertical direction. The lower surface of the pressure plate 7 abuts against the upper surface of the housing 8, thereby applying pressure to the housing 8 in the vertical direction and firmly fixing the housing 8 to the base 1. The lower surface of the housing 8 abuts against the sealing gasket 102, ensuring the sealing effect.

[0028] The adjusting mechanism 3 includes a bidirectional screw 301 and a turbine 302. The bidirectional screw 301 is rotatably connected inside the base 1, and the turbine 302 is fixedly installed in the middle of the outer surface of the bidirectional screw 301.

[0029] A rotating rod 303 is rotatably connected inside the base 1. A worm 304 is fixedly installed on the outer surface of one end of the rotating rod 303. The worm 304 and the turbine 302 are meshed and connected. One end of the rotating rod 303 extends to the outer surface of the base 1. A handle 305 is fixedly installed on one end of the rotating rod 303.

[0030] The bidirectional screw 301 has moving plates 306 threadedly connected to both the positive and negative threads, and both sets of moving plates 306 are slidably connected to the inside of the base 1.

[0031] When it is necessary to place quartz crystals of different sizes, the handle 305 is turned, which drives the rotating rod 303 to rotate. Since the worm 304 at one end of the rotating rod 303 is meshed with the turbine 302 on the bidirectional screw 301, the rotation of the rotating rod 303 will cause the bidirectional screw 301 to rotate. The moving plate 306 on the positive and negative threads of the bidirectional screw 301 will move in opposite directions when the bidirectional screw 301 rotates. Because the moving plate 306 is slidably connected to the inside of the base 1, its rotational freedom is restricted, thereby ensuring that the moving plate 306 can only move along the axial direction of the bidirectional screw 301, so as to limit and fix quartz crystals of different sizes and improve the flexibility of use.

[0032] The fixing mechanism 4 includes a fixing plate 401. The fixing plate 401 is fixedly installed on one end of the movable plate 306. The fixing plate 401 is threadedly connected to the inside of the fixing plate 401.

[0033] Limiting plates 403 are fixedly installed at one end of each limiting screw 402;

[0034] When it is necessary to place the quartz crystal on the base 1, place the quartz crystal under the fixing mechanism 4, and then rotate the limiting screws 402 on the two sets of fixing mechanisms 4 so that the limiting plate 403 limits and fixes the quartz crystal, thereby completing the installation of the quartz crystal.

[0035] In use, when it is necessary to place the quartz crystal on the base 1, place the quartz crystal under the fixing mechanism 4, and then rotate the limiting screws 402 on the two sets of fixing mechanisms 4 so that the limiting plate 403 limits and fixes the quartz crystal, thereby completing the installation of the quartz crystal. Then, place the housing 8 inside the limiting groove 101 and abut against the sealing gasket 102 to cover the quartz crystal. Then, the electric push rod 6 works, and the output end of the electric push rod 6 pushes the pressure plate 7 downward. Since the pressure plate 7 is slidably connected to the bracket 5, the pressure plate 7 can only move downward in the vertical direction. The lower surface of the pressure plate 7 abuts against the upper surface of the housing 8, thereby applying pressure to the housing 8 in the vertical direction, firmly fixing the housing 8 on the base 1. The lower surface of the housing 8 abuts against the sealing gasket 102 to ensure the sealing effect.

[0036] When it is necessary to place quartz crystals of different sizes, the handle 305 is turned, which drives the rotating rod 303 to rotate. Since the worm 304 at one end of the rotating rod 303 is meshed with the turbine 302 on the bidirectional screw 301, the rotation of the rotating rod 303 will cause the bidirectional screw 301 to rotate. The moving plate 306 on the positive and negative threads of the bidirectional screw 301 will move in opposite directions when the bidirectional screw 301 rotates. Because the moving plate 306 is slidably connected to the inside of the base 1, its rotational freedom is restricted, thereby ensuring that the moving plate 306 can only move along the axial direction of the bidirectional screw 301, so as to limit and fix quartz crystals of different sizes and improve the flexibility of use.
