The utility model content
The purpose of the utility model is to overcome the defective that exists in the prior art, designs the combined type compression-type track vibration-reducing device that a kind of rubber and ironware divide body structure, practice thrift cost.
For realizing above-mentioned purpose, the technical scheme of the utility model is a kind of combined type compression-type track vibration-reducing device of design, comprises base, elastic damping components, anticreep securing member and support rail plate; Wherein, Have the rectangle via hole on the plane of base; The upper surface of opposite side is laid with five sawtooth hook eaves at least in the left and right sides of rectangle via hole; Sawtooth hook eaves is positioned at the upper surface of base, and sawtooth hook eaves is extended to the center by rectangle via hole border on length, and the side that the rectangle via hole is not provided with sawtooth hook eaves has the anticreep securing member installing port of rectangle; The bottom of support rail plate is the rectangular preiection structure; The left and right sides of rectangular preiection structural base be laid with base on the prominent hook of sawtooth of sawtooth hook eaves corresponding number; And sawtooth hook eaves can overlap mutually with the prominent hook of sawtooth and cooperate, and the spacing between the prominent hook of adjacent sawtooth is consistent with the width of sawtooth hook eaves; The elastic shock attenuation parts have the rectangle via hole;
Its annexation: base is provided with the horizontal positioned that faces up of sawtooth hook eaves; The elastic shock attenuation parts are installed on the base plane; The rectangle via hole of elastic shock attenuation parts gets out of the way the sawtooth hook eaves on the base, and after the rectangular preiection structure of support rail plate was passed the rectangle via hole of elastic shock attenuation parts and base, the sawtooth hook eaves of prominent hook of the sawtooth of support rail plate and base staggered each other; The support rail plate is pushed away flat along level, the prominent hook of sawtooth of support rail plate is overlapped with the sawtooth hook eaves of base each other cooperate; The anticreep securing member be installed in base the installing port place and with the installing port interference fit.
The width of said sawtooth hook eaves is consistent with the width of the prominent hook of sawtooth.
Said elastic damping components is a rubber parts.
Also comprise protective sleeve, protective sleeve is installed on the prominent hook gib head of said sawtooth.
The utility model is achieved in that and earlier elastic damping components is installed on the base; Spacing buffer unit is installed on the prominent hook gib head of sawtooth of support rail plate; The prominent hook of support rail bladed saw tooth overlaps mutually with base sawtooth hook eaves and cooperates installation; Support rail plate and base are pushed away flat, again with the anticreep securing member insert from the base bottom base installing port and with the installing port interference fit.
The advantage and the beneficial effect of the utility model are: the manufacturing process that the structure of the utility model adopts ironware and rubber parts to divide body structure; Because elastic damping components, support rail plate and base are through assembling; Therefore be easy to dismounting and change, greatly reduce use cost thereby only need change elastic damping components during repair and replacement; For the different designs requirement in different vibration dampings location, as long as carry out rational performance adjustment to elastic damping components separately, assembling gets final product then, has guaranteed the performance variation of shock absorber.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is further described.Following examples only are used for more clearly explaining the technical scheme of the utility model, and can not limit the protection domain of the utility model with this.
To shown in Figure 8, the technical scheme of the utility model is a kind of combined type compression-type track vibration-reducing device, comprises base 3, elastic damping components 2, anticreep securing member 4 and support rail plate 1 like Fig. 1; Wherein, Have the rectangle via hole on the plane of base 3; The upper surface of opposite side is laid with five sawtooth hook eaves 31 at least in the left and right sides of rectangle via hole; Sawtooth hook eaves 31 is positioned at the upper surface of base 3, and sawtooth hook eaves 31 is extended to the center by rectangle via hole border on length, and the side that the rectangle via hole is not provided with sawtooth hook eaves 31 has anticreep securing member 4 installing ports of rectangle; The bottom of support rail plate 1 is the rectangular preiection structure; The left and right sides of rectangular preiection structural base be laid with base 3 on the prominent hook 11 of sawtooth of sawtooth hook eaves 31 corresponding numbers; And sawtooth hook eaves 31 can overlap mutually with the prominent hook 11 of sawtooth and cooperate, and the spacing between the prominent hook 11 of adjacent sawtooth is consistent with the width of sawtooth hook eaves 31; Elastic shock attenuation parts 2 have the rectangle via hole;
Its annexation: base 3 is provided with the horizontal positioned that faces up of sawtooth hook eaves 31; Elastic shock attenuation parts 2 are installed on base 3 planes; The rectangle via hole of elastic shock attenuation parts 2 gets out of the way the sawtooth hook eaves 31 on the base 3; After the rectangular preiection structure of support rail plate 1 is passed the rectangle via hole of elastic shock attenuation parts 2 and base 3; The prominent hook 11 of the sawtooth of support rail plate 1 staggers with the sawtooth hook eaves 31 of base 3 each other, support rail plate 1 is pushed away flat along level, the prominent hook 11 of sawtooth of support rail plate 1 is overlapped with the sawtooth hook eaves 31 of base 3 each other cooperate; Anticreep securing member 4 be installed in base 1 the installing port place and with the installing port interference fit.
