Embodiment 1
[0074] see Figure 1-Figure 2 , this embodiment proposes a vibration-damping and heat-dissipating locking device with adjustable vibration-damping frequency, including a locking device body, the locking device body including a bar-shaped base 1, and the bottom of the bar-shaped base 1 is provided with an elastic The heat conduction pad 5, in this embodiment, the elastic heat conduction pad 5 is a heat conduction rubber pad, the rubber pad has a certain rigidity, and has heat conduction performance, and the elastic heat conduction pad 5 is solidified on the strip-shaped the bottom of base 1;
[0075] The two ends of the strip-shaped base 1 are slopes, and the slopes at both ends are symmetrical about the center line of the strip-shaped base 1. In this embodiment, the slopes are surfaces inclined from top to bottom, shaped like The slope direction of the slope. The two slopes of the bar-shaped base 1 are respectively provided with a slide block one 2 and a slide block two 3, t...
Embodiment 2
[0089] The difference between this embodiment and embodiment 1 is:
[0090] The number of the elastic damping blocks is 2n+1 (n≥1), wherein the nth one is arranged in the center, and every other two identical elastic damping blocks are symmetrically arranged on the two sides of the nth elastic damping block. side. see Figure 7 , in the initial state, the distances from the top of the first elastic damping block, the second elastic damping block, ..., the top of the nth elastic damping block to the surface of the guide rail 101 on the chassis 10 are A1, A2, ..., An.
[0091] The design parameters of a vibration-damping and heat-dissipating locking device with adjustable vibration-damping frequency are as follows:
[0092] Set each parameter symbol as follows:
[0093] α: Angle between the sliding slope and the bottom surface of the locking device strip seat;
[0094] P: lock screw 4 pitch;
[0095] B: Rotation angle of locking screw 4;
[0096]X: screw 4 rotation depth; ...

Abstract
The invention relates to the technical field of vibration reduction and locking of electronic equipment, aims to solve the problems that a vibration reduction device in the prior art is non-adjustable in vibration reduction frequency and poor in universality for different equipment, and provides a vibration reduction and heat dissipation locking device with adjustable vibration reduction frequency, which comprises a locking device body, and an elastic heat conduction pad is arranged at the bottom of the locking device body; a plurality of elastic vibration reduction blocks are arranged on the locking device body, and a vibration reduction elastic component is arranged in each elastic vibration reduction block; an adjusting part is arranged on the locking device body, and different elastic vibration reduction block combinations can be in contact with a case guide rail by adjusting the adjusting part, so that the vibration reduction frequency of the locking device is adjusted; and the device has the beneficial effects that according to the vibration reduction frequency requirements of different modules, the elastic vibration reduction blocks of different combinations make contact with the case guide rail, the vibration reduction frequency is adjusted, the mechanical environment of the module is improved, the environmental adaptability of the module under the vibration condition is improved, reliability is high, universality is good, and meanwhile, the elastic heat conduction pad is used for conducting heat.
Description
technical field [0001] The invention relates to the technical field of vibration reduction and locking of electronic equipment, in particular to a vibration reduction and heat dissipation locking device with adjustable vibration reduction frequency. Background technique [0002] In radar and electronic warfare equipment, the array system is more and more widely used, and the standardization of different functional modules is getting higher and higher. The use of standardized modules can quickly realize functional integration and form radar and electronic warfare functional systems. At the same time, the vibration environment of radar and electronic warfare equipment is harsh and has high heat dissipation requirements. Therefore, higher requirements are put forward for the stability of radar and electronic warfare equipment in vibration and high temperature environments. [0003] At present, materials such as rubber pads, steel wire ropes, and springs are widely used in the ...
