Abstract
The utility model discloses a high-speed 360-degree rotary connector. According to the technical scheme, the high-speed 360-degree rotary connector is characterized by comprising a first tubular shell and a second tubular shell. The joint of the first and second tubular shells is provided with a bearing whereby the first and second tubular shells are in rotation fit. The inner wall of the first tubular shell is provided with a first limit projection. The outer wall of the second tubular shell is provided with a second limit projection. The first and second limit projections are in contact connection with the bearing respectively. A positioning bush is in contact connection with the inside of a passage of the first tubular shell and covers the second tubular shell. The positioning bush and the bearing are disposed on two symmetric sides of the first limit projection. An O-shaped seal ring is arranged between the first limit projection and the positioning bush. The O-shaped seal ring is provided with at least two symmetric buffer grooves which locate on one side of the positioning bush and one side of the first limit projection respectively. Impact force borne by the O-shaped seal ring can be buffered by the buffer grooves, so that the O-shaped seal ring and the positioning bush are protected effectively.

At present, on market, there are a kind of 360 ° of high-speed joints, it comprises that socket connects and be equipped with the first tubular shell and second tubular shell of passage, the joint of the first tubular shell and the second tubular shell is provided with and makes them both form the bearing that rotation coordinates, the inwall of the first tubular shell is provided with the first positive stop lug boss, the outer wall of the second tubular shell is provided with the second positive stop lug boss, the first positive stop lug boss forms to conflict with bearing respectively with the second positive stop lug boss and is connected, in the passage of described the first tubular shell, also conflict and be connected with setting sleeve, setting sleeve is set on the second tubular shell, and setting sleeve and bearing are placed in respectively the symmetrical both sides of the first positive stop lug boss, between the first positive stop lug boss and setting sleeve, be provided with O-ring seals.
Because 360 ° of high-speed joints of this structure are when connecting transmission medium, setting sleeve more or less can be along the first tubular shell axial slip, between setting sleeve and O-ring seals, can form certain impact force, cause setting sleeve or/and wearing and tearing appear in O-ring seals, thereby affect the working life of whole 360 ° of high-speed joints.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of 360 ° of high-speed joints, these 360 ° of high-speed joints can effectively reduce even to eliminate and cause setting sleeve or/and the situation of wearing and tearing appears in O-ring seals, extend the working life of whole 360 ° of high-speed joints.
For achieving the above object, the utility model provides following technological scheme: a kind of 360 ° of high-speed joints, comprise that socket connects and be equipped with the first tubular shell and second tubular shell of passage, the joint of the first tubular shell and the second tubular shell is provided with and makes them both form the bearing that rotation coordinates, the inwall of the first tubular shell is provided with the first positive stop lug boss, the outer wall of the second tubular shell is provided with the second positive stop lug boss, the first positive stop lug boss forms to conflict with bearing respectively with the second positive stop lug boss and is connected, in the passage of described the first tubular shell, also conflict and be connected with setting sleeve, setting sleeve is set on the second tubular shell, and setting sleeve and bearing are placed in respectively the symmetrical both sides of the first positive stop lug boss, between the first positive stop lug boss and setting sleeve, be provided with O-ring seals, described O-ring seals is provided with two buffer grooves at least symmetrically, described buffer groove is placed in respectively corresponding setting sleeve one side and corresponding the first positive stop lug boss one side.
By adopting technique scheme, can cushion the impact force that O-ring seals is subject to by buffer groove, effectively protect O-ring seals and setting sleeve.
The utility model is further set to: described buffer groove be provided with two and these two buffer groove sizes identical, be shaped as the ring suitable with O-ring seals.
By adopting technique scheme, can realize and cushion equably the impact force that O-ring seals is subject to by two size buffer grooves identical, that be shaped as ring, effectively protect O-ring seals and setting sleeve.
The utility model is further set to: described O-ring seals consists of urethane rubber material.
By adopting technique scheme, not only high resilience of seal ring, rebound elasticity and tear strength that polyurethane material forms, also there is anti abrasive advantage, further extended the working life of O-ring seals, thereby indirectly extended the working life of whole 360 ° of high-speed joints.
