Through the provided spring, the buffer plate can have a good buffering and shock-absorbing effect when it is in the movable groove.

[0004] According to the above patent, some existing constant temperature crystal oscillators are mostly shock-absorbing only by springs. However, if the shock-absorbing structure of the spring does not have a certain damping effect when the spring is deformed, the vibration amplitude of the constant temperature crystal oscillator will increase, thereby causing an adverse effect on its working stability and accuracy. Utility Model Content

However, if the shock absorption structure does not have a certain damping effect when the spring is deformed, it will cause the vibration amplitude of the constant temperature crystal oscillator to increase, thereby causing an adverse effect on its working stability and accuracy.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary structure for a constant temperature crystal oscillator heat dissipation and shock absorption device, comprising a constant temperature crystal oscillator body, a plurality of heat dissipation openings are provided on both sides of the constant temperature crystal oscillator body, and a plurality of pins and a shock absorption unit are provided at the bottom of the constant temperature crystal oscillator body;

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model sets a shock absorbing unit, so that when the constant temperature crystal oscillator body vibrates, it can be shock-absorbing through the deformation of the spring body. When the spring body drives the movable plate to move up and down, the repulsive magnetic field generated by the same magnetic force between the first magnetic plate and the second magnetic plate and the damping force of the small damper itself can greatly reduce the vibration amplitude of the movable plate. In this way, it can be avoided that the vibration amplitude of the constant temperature crystal oscillator body increases due to the lack of damping effect of the shock absorbing structure of the above-mentioned patent, thereby affecting the normal operation of the constant temperature crystal oscillator body, thereby improving practicality.

[0023] The shock absorbing unit 4 includes a shell 41 fixedly connected to the bottom of the constant temperature crystal oscillator body 1, and a movable plate 42 is slidably connected inside the shell 41, and the movable plate 42 is fixedly connected to the pin 3, and a plurality of spring bodies 43, a small damper 44, a vertical rod 45 and a first magnetic plate 46 are fixedly connected to the top wall of the shell 41, and the spring body 43 and the small damper 44 are both fixedly connected to the movable plate 42, and a sliding sleeve 47 is sleeved on the surface of the vertical rod 45, and a connecting plate 48 is fixedly connected to the surface of the sliding sleeve 47, and one end of the connecting plate 48 is fixedly connected to a second magnetic plate 49, and the second magnetic plate 49 is fixedly connected to the movable plate 42.

[0025] As a technical optimization scheme of the utility model, by setting a dustproof net 5 and a screw 6, when the constant temperature crystal oscillator body 1 is dissipated through the heat dissipation port 2, the dustproof net 5 can be installed on one end of the heat dissipation port 2 through the screw 6, thereby preventing the internal components of the constant temperature crystal oscillator body 1 from having poor heat dissipation due to external dust entering the constant temperature crystal oscillator body 1 through the heat dissipation port 2, thereby improving practicality.

[0026] refer to Figure 1 and Figure 4 A plurality of fixing plates 7 are fixedly connected to both the left and right sides of the constant temperature crystal oscillator body 1 , and the fixing plates 7 are fixedly connected to the housing 41 .

[0027] As a technical optimization solution of the utility model, by setting a fixing plate 7, the connection effect between the constant temperature crystal oscillator body 1 and the shell 41 is increased, thereby avoiding the constant temperature crystal oscillator body 1 from being separated from the shell 41 during shock absorption, thereby improving practicality.

[0028] refer to Figure 1 A hole is provided on the right side of the shell 41, and an inspection window 8 is fixedly connected inside the hole.

[0029] As a technical optimization solution of the present invention, by providing the inspection window 8, people can more conveniently observe whether the shock absorbing unit 4 inside the shell 41 needs to be replaced or repaired, thereby improving practicality.

[0030] refer to Figure 1 and Figure 2 The bottom end of the vertical rod 45 is fixedly connected to the limit plate 9, and the limit plate 9 is in contact with the sliding sleeve 47.

[0031] As a technical optimization solution of the present invention, by providing the limiting plate 9, the sliding sleeve 47 is prevented from being separated from the vertical rod 45 when moving up and down, thereby improving the limiting performance.

[0034] The working principle and use process of the utility model are as follows: when the constant temperature crystal oscillator body 1 is vibrated, the resilience of the spring body 43 can be used to make the movable plate 42 slide up and down inside the shell 41, so as to achieve the shock-absorbing effect of the constant temperature crystal oscillator body 1, and after the spring body 43 is deformed, the second magnetic plate 49 can be driven by the movable plate 42 to move up and down on the surface of the vertical rod 45, and under the dual action of the repulsive magnetic field generated by the same magnetic force between the first magnetic plate 46 and the second magnetic plate 49 and the damping force of the small damper 44 itself, the resilience of the spring body 43 and the shaking amplitude of the movable plate 42 can be reduced, thereby indirectly avoiding the phenomenon that the shell 41 drives the constant temperature crystal oscillator body 1 to shake violently, thereby improving the stability of the constant temperature crystal oscillator body 1 during shock absorption.

[0035] To sum up: the auxiliary structure of the constant temperature crystal oscillator heat dissipation and shock absorption device, through the shock absorption unit 4, solves the problem that some existing constant temperature crystal oscillators are mostly shock-absorbing only by springs. However, if the shock absorption structure does not have a certain damping effect when the spring is deformed, it will cause the vibration amplitude of the constant temperature crystal oscillator to increase, thereby causing an adverse effect on its working stability and accuracy.
