SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to the not enough of above-mentioned prior art, provide a spacing buffer structure of improvement type, avoided the friction of buffering ring and connecting rod, increased its life.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a spacing buffer structure of improvement type, includes the buffering ring and distributes in the interior spacing cover of buffering ring lateral part, its characterized in that, interior spacing cover middle part is equipped with the assembly hole that can assemble the linkage with the shock absorber connecting rod, the terminal surface of interior spacing cover towards buffering ring one side is equipped with the ring channel that can with the mutual gomphosis of buffering ring, the ring channel is equipped with the opening towards buffering ring one side, the ring channel is transversal personally submits trapezoidal and the both sides limit that is located the opening part sets up towards ring channel cross section central line slope respectively, the one end of spacing cover is equipped with the anticreep boss that distributes in the side towards the buffering ring, the ring channel medial surface be equipped with can with the anticreep groove of anticreep boss gomphosis.
By adopting the technical scheme, the structure of the inner limiting sleeve is improved, the buffer ring is enabled to be relatively and fixedly connected with the inner limiting sleeve, compared with the prior art, the buffer ring and the inner limiting sleeve do not move relatively, so that the friction between the buffer ring and the connecting rod is avoided, and the service life of the buffer ring is prolonged; wherein mainly through the ring channel, and the size design of ring channel is that the outside is little (also opening part), and the inside is big (ring channel inner chamber is big) to the external diameter of buffer ring designs an anticreep boss, dual anti-disengaging structure, makes buffer ring and interior spacing cover be connected inseparabler, is difficult for the pine to take off.
The above-mentioned improvement type spacing buffer structure can further set up as: the end face of the inner limiting sleeve, which faces one side of the buffer ring, is provided with a first guide inclined plane corresponding to the opening of the annular groove, and the first guide inclined plane can be in conduction connection with the opening and is inclined towards the outside by taking the central line of the cross section of the annular groove as the center.
By adopting the technical scheme, the first guide inclined plane is arranged, so that the buffer ring can conveniently enter the annular groove, and the assembly is convenient.
The above-mentioned improvement type spacing buffer structure can further set up as: the inner limiting sleeve is characterized in that a sealing linkage groove and a sealing ring embedded in the sealing linkage groove are arranged in the middle of the inner limiting sleeve, the sealing linkage groove is located at the end part of the assembly inner hole and is coaxial and in conduction connection with the assembly inner hole, and the inner side edge of one end, close to the assembly inner hole, of the sealing linkage groove is obliquely arranged towards the outer side by taking the central axis of the inner limiting sleeve as the center.
By adopting the technical scheme, the sealing ring is not easy to slip from the sealing linkage groove.
The above-mentioned improvement type spacing buffer structure can further set up as: and a second guide inclined plane is arranged at the end part of the sealing linkage groove far away from the assembly inner hole.
By adopting the technical scheme, the sealing ring can conveniently enter the sealing linkage groove, and the assembly is convenient.
The present invention will be described in further detail with reference to the accompanying drawings and examples.
