Abstract
The invention relates to a self-pressing type clamping sleeve. The self-pressing type clamping sleeve comprises a connecting port, an annular clamping sleeve, a spring, a ball and a rubber ring, wherein the annular clamping sleeve is a hollow cylinder with one sealed end, a through hole which is coaxially connected with the connecting port is formed in the sealed end of the annular clamping sleeve, a clamping groove is formed in the inner wall of the annular clamping sleeve, the rubber ring is located between the clamping groove and the sealed end of the annular clamping sleeve, the rubber ring is coaxially fixed to the surface of the inner wall of the annular clamping sleeve, an opening enabling a corresponding buckle to enter the clamping groove is formed in one end of the clamping groove, a groove used for limiting the corresponding buckle is formed in the other end of the clamping groove, a sealed cavity is formed inside the annular clamping sleeve right facing the groove, the spring and the ball are arranged inside the cavity in sequence, a round hole is formed in the bottom of the cavity, and the bore diameter d of the round hole is smaller than the diameter D of the ball. Through the method, the clamping structure of the self-pressing type clamping sleeve is greatly improved, self-locking capacity of the clamping sleeve is guaranteed, and the clamping structure is not prone to automatic falling through the matching between a self-locking screw and the groove.
Description
Technical field
The present invention relates to and relate to hardware fitting field, particularly relate to a kind of self-pressure type clamping cover.
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.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of self-pressure type clamping cover, and it is reasonable in design, and structure is simple, and solving between clamping cover with corresponding buckle can not the problem of self-locking.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is to provide a kind of self-pressure type clamping cover, comprises interface, ring-shaped clamping sleeve, spring, hoodle 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; Just an airtight cavity is being offered to the inside of the described ring-shaped clamping sleeve of described groove; Described spring and hoodle is placed successively in described cavity; The bottom of described cavity is provided with circular hole; The aperture d of described circular hole is less than the diameter D of described hoodle.
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 self-pressure type clamping cover, 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 the spring-pinball structure of automatic rebounding with coordinating of groove.

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 5, the embodiment of the present invention comprises:
A kind of self-pressure type clamping cover, comprises interface 1, ring-shaped clamping sleeve 2, spring 3, hoodle 4 and rubber ring 5; 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 is provided with buckling groove 6; Described rubber ring 5 is between described buckling groove 6 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 5; One end of described buckling groove 6 is provided with and holds corresponding buckle and enter opening in groove; The other end of described buckling groove 6 is provided with for the spacing groove 7 of corresponding buckle; Just an airtight cavity is being offered to the inside of the described ring-shaped clamping sleeve 2 of described groove 7; Described spring 3 and hoodle 4 is placed successively in described cavity; The bottom of described cavity is provided with circular hole; The aperture d of described circular hole is less than the diameter D of described hoodle 4.The height of the lower surface of described rubber ring 5 is between the upper surface and lower surface height of described groove 7.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 6, snaps onto in groove 7, due to the position relationship of rubber ring 5, preliminary for buckle can be pressed in groove 7 after buckling groove 6 rotates.Therefore simultaneously, ring-shaped clamping sleeve 2 inside just right at groove 7 is provided with the cavity laying spring 3 and hoodle 4, spring 3 compresses hoodle 4 downwards, hoodle 4 will protrude from the circular hole of cavity bottom, due to the size relationship of circular hole and hoodle, hoodle 4 part is protruded can push down the buckle being now positioned at groove 7 firmly, realizes self-locking and makes buckle difficult drop-off.
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.
