A kind of (application number: 201110338879.7) of the external connecting sleeve for fixed buffer disclosed in Chinese patent literature, external connecting sleeve body, bolt and piston rod sleeve pipe, external connecting sleeve body forms oval plate shape, piston rod sleeve pipe one end is connected with external connecting sleeve body one end face, bolt comprises head and screw rod, the screw rod of bolt runs through the opposite end surface of external connecting sleeve body, and the head of bolt is connected the end contact of piston rod sleeve pipe with external connecting sleeve body.But do not arrange shock-damping structure in this external connecting sleeve, therefore its comfort is not high.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of external connecting sleeve assembly with good damping effect.
The purpose of this utility model realizes by following technical proposal: external connecting sleeve assembly, comprise the external connecting sleeve in coaxial setting and interior coupling sleeve, the lower end of described interior coupling sleeve is provided with dust collar, it is characterized in that, the lateral wall of described interior coupling sleeve is provided with the connecting portion of undulate, elastic body is provided with between described external connecting sleeve and described interior coupling sleeve, and described elastomeric lower end is connected with dust collar, described interior coupling sleeve and described dust collar are all axially arranged with the through hole passed for bolt.
In use, through through hole, bumper is connected to automobile by this external connecting sleeve assembly by bolt.Dust-proof function is realized by arranging dust collar.Due to external connecting sleeve and described in be provided with elastic body between coupling sleeve, because now this external connecting sleeve assembly can absorb external force, there is good shock-absorbing function, improve the traveling comfort of use.Connecting portion undulate, enables elastic body be connected with interior coupling sleeve preferably, has connection comparatively firmly advantage.
In above-mentioned external connecting sleeve assembly, described elastic body is connected mutually by injection moulding and described external connecting sleeve, interior coupling sleeve and dust collar.Adopt the mode of injection moulding to connect, there is the advantage be connected firmly.
In above-mentioned external connecting sleeve assembly, be provided with the dust boot of tubular between the lower end of described external connecting sleeve and the outside of described dust collar, the upper end of described dust boot and the lower end of described external connecting sleeve socket-connect.By arranging dust boot, good dustproof effect being played to the cavity of external connecting sleeve, avoiding elastomeric aging, there is longer advantage in service life.
In above-mentioned external connecting sleeve assembly, the edge of described dust collar has the bending part of bending downwards, and the lower end of described dust boot is connected to the bending part of described dust collar by elastic ring.The lower end of dust boot is connected to the bending part of dust collar by elastic ring, have and connect the good advantage of effect.
In above-mentioned external connecting sleeve assembly, the upper end of described interior coupling sleeve has the location division of folding of turning on one's side outward, and described elastomeric upper end is resisted against on described location division.By arranging location division, to elastic body, there is good locating effect.
In above-mentioned external connecting sleeve assembly, the lower end of described dust boot has the sealing convex body of past axis direction inclination.
Compared with prior art, this external connecting sleeve assembly has the following advantages:
1, in external connecting sleeve and described in be provided with elastic body between coupling sleeve, because now this external connecting sleeve assembly can absorb external force, there is good shock-absorbing function, improve the traveling comfort of use;
2, by arranging dust boot, good dustproof effect being played to the cavity of external connecting sleeve, avoiding elastomeric aging, there is longer advantage in service life;
3, the lower end of dust boot is connected to the bending part of dust collar by elastic ring, has and connects the good advantage of effect.
