[0002] The quartz crystal resonator is an important electronic component, and is widely used in communication, computer, industrial control and other fields. Its main function is to provide high-precision, high-stability frequency signal for electronic equipment. With the continuous development of technology, the reliability and durability of the quartz crystal resonator have an increasingly significant impact on the overall performance of the product. However, due to the high sealing performance requirement of the quartz crystal resonator, how to ensure the good sealing performance of the shell and prevent the influence of external environmental factors on the internal components of the resonator has become an important technical problem to be solved in this field.

[0003] In the prior art, the common quartz crystal resonator usually adopts ordinary sealing ring or adhesive sealing structure. Although this kind of structure can realize basic sealing, there are the following problems in actual use: on the one hand, the sealing performance may decrease due to long-time vibration or external pressure, thereby causing the internal components to be eroded by dust, moisture and other external environment; on the other hand, the existing sealing structure is relatively complex when disassembled, and the sealing element is easily damaged due to improper operation, thereby affecting the secondary use. In addition, many sealing structures cannot meet the requirements of high sealing efficiency and convenient disassembly, which limits the maintenance efficiency of the equipment.

[0007] Further, the docking plate is symmetrically provided with protrusions on both sides, the protrusions extend outward, and the surface of the protrusions is vertically rotated through an adjusting bolt, and the top of the adjusting bolt is provided with a knob.

[0008] Further, the two horizontal plates are respectively screwed on the protrusions, and the protrusions are penetrated by the horizontal plates, and the both sides of the horizontal plates are provided with through holes.

[0009] Further, the through hole is internally rotated and penetrated by a rotating shaft, and the extrusion rod is fixed at the bottom of the rotating shaft.

[0010] Further, the top of the rotating shaft is provided with a limiting plate, and the limiting plate is placed on the upper surface of the horizontal plate.

[0011] Further, the upper surface of the sealing bottom plate is fixed with a quartz wafer, the quartz wafer is placed in the shell, and the both sides of the quartz wafer are welded with electrodes, and the two electrodes are penetrated through the sealing bottom plate.

[0012] Compared with the prior art, the beneficial effects of the present application are:

[0013] Through the structural design of the present application, the sealing performance between the shell and the sealing bottom plate is significantly improved. The sealing bottom plate is tightly attached to the stepped surface through the rubber sealing ring, and the extrusion rod is driven by the horizontal plate to exert pressure on the sealing bottom plate, thereby ensuring the sealing effect. This structure can effectively prevent external air or liquid from entering the interior of the quartz crystal resonator, overcome the problem of sealing performance decline due to vibration or external force in the prior art, and improve the reliability and service life of the equipment.

[0014] By setting the adjusting bolt and the knob, the user can conveniently adjust the lifting position of the horizontal plate, thereby controlling the pressure of the extrusion rod on the sealing bottom plate. When disassembling, the horizontal plate is lifted by rotating the adjusting bolt, and the extrusion rod is separated from the sealing bottom plate, which is convenient for maintaining or replacing the interior of the resonator. This adjustable design effectively solves the problem of complex disassembly of the traditional sealing device, and improves the use efficiency.

[0015] The quartz wafer installed on the sealing bottom plate and the electrodes welded on both sides thereof penetrate the sealing bottom plate, realizing effective transmission of internal electronic signals, and ensuring that the influence of the external environment on the quartz wafer is minimized. The close combination of the sealing bottom plate and the shell provides a reliable protection environment for the internal elements, avoiding the performance decline or failure of the elements caused by insufficient sealing in the prior art.

[0016] The overall structure realizes stable installation and convenient disassembly of the sealing assembly, effectively solves the technical problem that the traditional sealing device cannot balance high sealing performance and convenient operation, and is suitable for the scene of quartz crystal resonator requiring high sealing performance.
