A kind of pneumatic clamping female connector
Technical field
The present invention relates to hardware fitting field, particularly relate to a kind of pneumatic clamping female connector.
Background technique
in hardware fitting, have a kind of clamping cover of external corresponding connected element on the mouth of pipe or aperture, this structure realizes signaling transfer point easily by the mouth of pipe equipment that is connected in its main body.The locking mechanism of clamping cover can use the mode of screw threads for fastening usually, but the machining accuracy of screw mouth is difficult to control relatively; And screw thread also gets rusty easily in permanent wet environment, the inconvenience of handling can be brought.Thus there is some connection mouths using interface arrangment, and these connection mouths meeting existing defects in the ability of locking; Especially just there will be when the pretightening force connected is not enough the problem being difficult to lock completely.In the structure of some full-automations, in the environment that manual mechanical structure cannot complete, this structure that cannot lock is more difficult.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of pneumatic clamping female connector, and it is reasonable in design, and structure is simple, solves clamping in automation state and overlaps kayser between corresponding buckle and the problem of locking.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is to provide a kind of pneumatic clamping female connector, comprises interface, ring-shaped clamping sleeve, needle-like cylinder and rubber ring; Described ring-shaped clamping sleeve is the hollow cylinder that one end is closed; The closed end of described ring-shaped clamping sleeve is provided with the coaxial through hole connecting described interface; The inwall of described ring-shaped clamping sleeve is provided with buckling groove; Described rubber ring is between described buckling groove and the closed end of described ring-shaped clamping sleeve; The inner wall surface of described ring-shaped clamping sleeve coaxially fixes described rubber ring; One end of described buckling groove is provided with and holds corresponding buckle and enter opening in groove; The other end of described buckling groove is provided with for the spacing groove of corresponding buckle; Described needle-like cylinder is set firmly outside described ring-shaped clamping sleeve above described groove; The piston rod of described needle-like cylinder advances in described groove; The hairbrush of protrusion is provided with bottom the inwall of described ring-shaped clamping sleeve.
Preferably, the height of the lower surface of described rubber ring is between the upper surface and lower surface height of described groove.
Preferably, the radially-outer surface of described ring-shaped clamping sleeve is also provided with otic placode.
The invention has the beneficial effects as follows: provide a kind of pneumatic clamping female connector, it has done a large amount of architecture advances in the structure of clamping, ensure that the self-lock ability that clamping is overlapped; And make interface arrangment be not easy Automatic-falling by cylinder push-rod structure with coordinating of groove.

In accompanying drawing, the mark of each parts is as follows: 1, interface; 2, ring-shaped clamping sleeve; 3, needle-like cylinder; 4, rubber ring; 5, buckling groove; 6, groove; 7, hairbrush; 8, otic placode.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, can be easier to make advantages and features of the invention be readily appreciated by one skilled in the art, thus more explicit defining is made to protection scope of the present invention.
Refer to accompanying drawing 1 to 3, the embodiment of the present invention comprises:
A kind of pneumatic clamping female connector, comprises interface 1, ring-shaped clamping sleeve 2, needle-like cylinder 3 and rubber ring 4; The hollow cylinder that described ring-shaped clamping sleeve 2 is closed for one end; The closed end of described ring-shaped clamping sleeve 2 is provided with the coaxial through hole connecting described interface 1; The inwall of described ring-shaped clamping sleeve 2 is provided with buckling groove 5; Described rubber ring 4 is between described buckling groove 5 and the closed end of described ring-shaped clamping sleeve 2; The inner wall surface of described ring-shaped clamping sleeve 2 coaxially fixes described rubber ring 4; One end of described buckling groove 5 is provided with and holds corresponding buckle and enter opening in groove; The other end of described buckling groove 5 is provided with for the spacing groove 6 of corresponding buckle; Described needle-like cylinder 3 is set firmly outside described ring-shaped clamping sleeve 2 above described groove 6; The piston rod of described needle-like cylinder 3 advances in described groove 6; The hairbrush 7 of protrusion is provided with bottom the inwall of described ring-shaped clamping sleeve 2.The height of the lower surface of described rubber ring 4 is between the upper surface and lower surface height of described groove 6.The radially-outer surface of described ring-shaped clamping sleeve 2 is also provided with otic placode 8.
During use, corresponding buckle enters from the opening buckling groove 5, snaps onto in groove 6, due to the position relationship of rubber ring 4, preliminary for buckle can be pressed in groove 6 after buckling groove 5 rotates.Therefore simultaneously, needle-like cylinder 3 arranges and is installed on ring-shaped clamping sleeve 2, the piston rod of needle-like cylinder 3 advances to groove 6 through the body of ring-shaped clamping sleeve 2, and the piston rod of such needle-like cylinder 3 just can push down the buckle being now positioned at groove 6 firmly, realizes self-locking and makes buckle difficult drop-off.Hairbrush 7 bottom the inwall being arranged on ring-shaped clamping sleeve 2 is then that preventing dust from falling into wherein affects switching performance for clearing up the body structure surface be mated.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
