Abstract
A kind of self-pressure type clamping of the utility model cover, comprises interface, ring-shaped clamping sleeve, spring, hoodle and rubber ring; Ring-shaped clamping sleeve is the hollow cylinder that one end is closed; The closed end of ring-shaped clamping sleeve is provided with the through hole of coaxial connection interface; The inwall of ring-shaped clamping sleeve is provided with buckling groove; Rubber ring is between buckling groove and the closed end of ring-shaped clamping sleeve; The inner wall surface of ring-shaped clamping sleeve coaxially fixes rubber ring; One end of buckling groove is provided with and holds corresponding buckle and enter opening in groove; The other end of buckling groove is provided with for the spacing groove of corresponding buckle; Just an airtight cavity is being offered to the inside of the ring-shaped clamping sleeve of groove; Spring and hoodle is placed successively in cavity; The bottom of cavity is provided with circular hole; The aperture d of circular hole is less than the diameter D of hoodle.By the way, 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 lock screw with coordinating of groove.
Description
Technical field
The utility model relates to hardware fitting field, particularly relates 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.
Model utility content
The technical problem that the utility model 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 utility model 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 beneficial effects of the utility model are: 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.
Accompanying drawing explanation

Fig. 4 is the B-B cross-sectional view of Fig. 2;
Fig. 5 is the partial enlarged view in Fig. 3;
In accompanying drawing, the mark of each parts is as follows: 1, interface; 2, ring-shaped clamping sleeve; 3, spring; 4, hoodle; 5, rubber ring; 6, buckling groove; 7, groove; 8, otic placode.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to accompanying drawing 1 to 5, the utility model is embodiment comprise:
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 embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description 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 utility model.
