Description
Technical Field
The utility model relates to a vibration isolation device.
Background
The existing traditional damping spring shock absorber adopts a spring as a main damping part, and achieves the vibration isolation effect through the elasticity of the spring. However, the existing steel spring shock absorber can generate high-frequency resonance due to the structural defects, and the damping force is small.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a low frequency, damping are big, eliminate high damping spring isolator of resonance amplitude phenomenon.
In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a high damping spring isolator, includes base, dabber, upper end cover, lower extreme cover and a plurality of spring, be equipped with the hole of sliding on the base, lower extreme cover fixed connection is on base upper portion, and the one end of dabber slides in with the hole of sliding and is connected, and the other end passes the lower extreme cover to with upper end cover fixed connection, all have the spacing projection of mutual disposition on the opposite flank of upper end cover and lower extreme cover, install respectively on corresponding spacing projection at the both ends of spring.
Preferably, the base is provided with a diagonal bracing rib.
Preferably, the upper part of the base is provided with a flanging, and the lower end cover is fixedly connected to the flanging through a bolt.
Preferably, the upper end cover is provided with a central hole, and the other end of the mandrel is fixedly connected with the central hole of the upper end cover.
Preferably, one end of the mandrel is provided with a sliding boss, and the sliding boss is connected with the sliding hole in a sliding manner.
After the structure of the oil adding device is adopted, the utility model discloses a spacing projection installation on the both ends of a plurality of springs and upper end cover and the lower end cover to the dabber is used for fixing a position upper end cover and lower end cover. In the use, the upper end cover can drive the mandrel to slide up and down in the sliding hole along with the vibration, and the vibration is offset through the spring. Therefore, the utility model has the advantages of low frequency and large damping, and eliminates the resonance amplitude phenomenon.
Drawings
Fig. 1 is a schematic view of the present invention;
fig. 2 is a top view of fig. 1.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrated in the accompanying drawings.
Referring to fig. 1 and 2, the high-damping spring vibration isolator comprises a base 1, a mandrel 2, an upper end cover 3, a lower end cover 4 and four springs 5, wherein a sliding hole 11 is formed in the base 1, the lower end cover 4 is fixedly connected to the upper portion of the base 1, one end of the mandrel 2 is connected with the sliding hole 11 in a sliding mode, the other end of the mandrel passes through the lower end cover 4 and is fixedly connected with the upper end cover 3, the opposite side surfaces of the upper end cover 3 and the lower end cover 4 are respectively provided with a limiting convex column 6 which are oppositely arranged, and two ends of each spring 5 are respectively installed on the corresponding limiting convex columns 6.
Referring to fig. 1, the base 1 is provided with diagonal bracing ribs 12. The inclined supporting ribs 12 can strengthen the structural strength of the base 1, and the movement stability of the spring 5 and the end cover which are arranged above the base is ensured.
Referring to fig. 1, a flange 13 is arranged at the upper part of the base 1, and the lower end cover 4 is fixedly connected to the flange 13 through bolts. The installation firmness of the lower end cover 4 and the base 1 is ensured, and the structural strength after installation is ensured.
Referring to fig. 1, a central hole is formed in the upper end cover 3, and the other end of the mandrel 2 is fixedly connected with the central hole of the upper end cover 3. During installation, the other end of the mandrel 2 penetrates into a central hole of the upper end cover 3, then the two end parts are leveled, and then the mandrel is fixed through welding.
Referring to fig. 1, a sliding boss 21 is arranged at one end of the mandrel 2, and the sliding boss 21 is connected with the sliding hole 11 in a sliding manner. The connection reliability of the sliding is ensured.
The utility model discloses a ninety degrees equipartitions at four spring 5 intervals between upper end cover 3 and lower end cover 4, the both ends of spring 5 carry on spacingly through corresponding spacing projection 6 that upper end cover 3 and lower end cover 4 set up relatively, guarantee that spring 5 can not break away from at extrusion and release in-process. The upper end of the mandrel 2 is welded and fixed with the central hole of the upper end cover 3, and the lower end of the mandrel passes through the central hole of the lower end cover 4 and is connected with the sliding hole 11 on the base 1 in a sliding manner. In the use process, the upper end cover 3 descends along with the acting force of the pressing down, and the spring 5 is promoted to be correspondingly extruded to offset the acting force of the pressing down, so that the damping effect is achieved. The utility model discloses a spring 5 adopts high-quality spring steel to make, and the vibration isolation effect can reach more than 95% to life is up to more than ten years, has spring damper's low frequency and the big dual some of damping, has eliminated other spring damper's resonance amplitude phenomenon.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
