Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

This specific embodiment is only an explanation of the utility model, and it is not a limitation of the utility model. After reading this description, those skilled in the art can make modifications to the embodiment without creative contribution according to needs, but as long as it is within the utility model All new claims are protected by patent law.

Embodiment 1, as shown in Figure 1 and Figure 2, in this technical solution, the separation design of the double-layer box is adopted, and the inner box 2 and the outer box 1 located outside the inner box 2 are respectively arranged, and all electronic components are Set in inner box 2. During the use of electric equipment, there will be vibrations in the three directions of front and back, up and down, and left and right, and the inner box 2 will also generate vibrations in three directions, which will be absorbed by the shock-absorbing structure in the technical solution.

First, in the vertical direction, the inner box 2 not only generates vertical vibration, but also has its own gravity support. This case adopts the scheme of secondary shock absorption in the vertical direction. Specifically, as shown in Fig. 2, a rubber layer 31 is provided under the inner box 2, and a supporting plate 33 is provided under the rubber layer 31, and the supporting plate 33 can be made of metal material. The deformation of the rubber layer 31 decomposes and absorbs the vibration in the vertical direction for the first time, realizing a first-level shock absorption in the vertical direction. Below the supporting plate 33, a damping spring 33 and a damper 34 are arranged in sequence from top to bottom. The upper end of the damping spring 33 is connected with the support plate 33 , and the lower end is connected with the damper 34 . The lower end of the damper 34 is connected with the surface of the outer case 1 . The second stage of decomposition and absorption of the vibration in the vertical direction is realized by the deformation of the damping spring 33 and the displacement of the damper 34 . The damper 34 and the damping spring 33 can adopt mature products in the prior art, and the specific models are not specifically limited in this case.

Secondly, in the lateral direction, there are vibrations in two directions, the front-back direction and the left-right direction. In the horizontal front-rear direction, there are front and rear elastic components 4 for shock absorption and buffering. As shown in Fig. 2 and Fig. 4, the left-right direction on the drawing of Fig. 2 is the front-rear direction mentioned in this article. Specifically, metal rubber columns 41 are provided on the outer surface of the side wall of the inner box 2 and the inner side wall of the outer box 1 . Metal rubber is a new material, which is a homogeneous elastic porous substance. It uses a certain process to discharge a certain quality, stretched, and spiral metal wires in a stamping or rolling mold in an orderly manner. In, and then formed by cold stamping method. Its raw material is metal wire, which has both the inherent properties of the chosen metal and its rubber-like elasticity. A plurality of elastic sheets 42 are arranged around the metal rubber column 41 , and the number of elastic sheets 42 can be defined according to the actual situation. Through the expansion and deformation of the elastic sheet 42, the sub-vibration in the front-rear direction is decomposed and absorbed for the first time, and the first-level vibration reduction in the front-back direction of the equipment is realized. The deformation of the metal rubber column 41 is used to perform the first sub-vibration in the front-back direction The secondary decomposition and absorption realizes the secondary vibration reduction in the front and rear directions of the equipment. In addition, in this embodiment, six elastic pieces 42 are arranged on the outer ring of each metal rubber column 41, and the installation position of the elastic pieces 42 is set so that when the displacement range caused by vibration reaches a predetermined level, the elastic pieces 42 are mutually restricted so that the The displacement and deformation in the direction cannot continue to increase, thereby ensuring that the elastic sheet 42 can work within its normal working range, and ensuring the service life of the vibration damping box of the electric equipment.

Again, in the other horizontal direction, namely the left and right directions, there are left and right elastic components 5 . In actual work, the vibration from the left and right directions is often the largest, so in this case, the left and right elastic components 5 adopt a three-layer shock-absorbing design. Specifically, as shown in FIG. 2 and FIG. 3 , the left-right direction of the drawing in FIG. 3 is the left-right direction described herein. The front-back direction mentioned above is the up-down direction of the drawing in FIG. 3 . The outer surface of outer case 1 is provided with mounting table 54, is provided with rotating shaft 55 on mounting table 54, and rotating shaft 55 is connected in the middle position of hard rod 51 by parts such as bearings and the like, makes hard rod 51 can be horizontally The direction rotates around the axis of rotation 55 . It also includes two sets of connecting rod buffer assemblies 52, which are respectively connected to both ends of the hard rod 51 by components such as joint bearings. Each connecting rod buffer assembly 52 includes a two-stage connecting rod, that is, a connecting rod one 521 and a connecting rod two 522, and a connecting rod spring 524 is used between the two connecting rods. Shock-absorbing rubber 523 is also installed in the cavity of spring 524 . One end of the second connecting rod 522 is connected with the hard rod 51, and the other end is connected with the first connecting rod 521 through the connecting rod spring 524, and the other end of the first connecting rod 521 is connected with the fixing device 53 through components such as joint bearings. The fixing device 53 is used to connect with the outer side wall of the inner box 2 . As shown in FIGS. 1 and 3 , the fixing device 53 includes a fixing block 531 connected and fixed to the inward 2 . The fixing block 531 and the boss 532 are provided with round holes for parts such as the pin shaft to pass through, and the pin shaft is connected with the joint bearing to realize the connection between the fixing device 53 and the connecting rod one 521 . The function of the boss 532 is to ensure that the fixed block 531 and the joint bearing do not interfere during the working process.

Through the compression or tensile deformation of the connecting rod spring 524, the sub-vibration in the left and right direction is decomposed and absorbed for the first time, and the first-level vibration reduction in the left and right direction of the equipment is realized. Through the rotation of the set hard rod 51, the two connecting rods The spring 524 is loaded evenly, and transmits the sub-vibration to the inner box 2 itself to offset the vibration, so that the sub-vibration in this direction is decomposed and absorbed for the second time, and the secondary vibration reduction in the left and right directions of the device is realized. Shock rubber 523, through the deformation of the metal rubber, the sub-vibration in the left and right directions is decomposed and absorbed for the third time.
