Description
Technical field
The utility model is related to a kind of inner cone circlip type contiguity heads used for rolling stock.Belong to fit sealing technical field.
Background technology
Circlip type connector used for rolling stock is for the connection of metal hard tube, existing clamp spring connector（Referring to Fig. 3）In the presence of
Problems with：1st, the existing clamp spring connector power transmission conical surface is too small, and not tight so as to cause pipe clip, pipe can rotate when serious, production
Raw unpredictable consequence；2nd, existing clamp spring joint sealing grade is low.
Invention content
The purpose of this utility model is to overcome above-mentioned deficiency provides inner cone circlip type contiguity head used for rolling stock.
What the purpose of this utility model was realized in：
Inner cone circlip type used for rolling stock touches head, its main feature is that：It includes packing nut, clamping ring, inner conical drogue, sealing
Circle and main body, sealing ring are located in the slot of the bottom of main body, and clamping ring is hollow frustum, and taper hole, taper hole are provided in inner conical drogue
Corresponding with the outside wall surface of clamping ring, right end and the sealing ring of inner conical drogue offset, the left end of clamping ring and the inner wall phase of packing nut
It supports, packing nut is with main body to be threadedly coupled.
A kind of inner cone circlip type contiguity head used for rolling stock of the utility model, the thread segment width of main body are slightly shorter than inner cone
The width of set.
A kind of inner cone circlip type contiguity head used for rolling stock of the utility model, inner conical drogue is mutual indepedent with main body, inner cone
Can move ahead crush seal circle after set stress.
A kind of inner cone circlip type contiguity head used for rolling stock of the utility model, clamping ring have contraction mouth.
Compared with prior art, the beneficial effects of the utility model are：
1. the clamping face of the utility model is the inner wall of whole section of clamping ring coordinated with inner conical drogue, clamping force is big, self-locking performance
It is good, take full advantage of the limited clamping space of clamp spring connector.
2. the sealing ring of the utility model is in bottom part body, while enough clamping faces are ensured, sealing etc. ensure that
Grade.

Specific embodiment
Referring to Fig. 1-2, the utility model is related to inner cone circlip types used for rolling stock to touch head, it includes packing nut 1, folder
Collar 2, inner conical drogue 3, sealing ring 4 and main body 5, sealing ring 4 are located in the slot 5.1 of the bottom of main body 5, and clamping ring 2 is hollow
Frustum is provided with taper hole 3.1 in inner conical drogue 3, and taper hole 3.1 is corresponding with the outside wall surface of clamping ring 2, right end and the sealing ring 4 of inner conical drogue 3
It offsets, the inner wall of the left end and packing nut 1 of clamping ring 2 offsets, and packing nut 1 is with main body 5 to be threadedly coupled.
The thread segment width of main body 5 is slightly shorter than the width of inner conical drogue 3.
Clamping ring 2 has contraction mouth, convenient for tightening so as to clamping metal hose
Operation principle：
The utility model inner cone circlip type used for rolling stock contiguity head, during installation, metal hose sequentially passes through packing nut
Sealing ring 4, is first placed in the slot 5.1 of main body 5 by the 1st, clamping ring 2, inner conical drogue 3, sealing ring 4 and main body 5, then by inner conical drogue 3
It fills in main body 5, the right end of inner conical drogue 3 resists sealing ring 4, and then clamping ring 2 is put into inner conical drogue 3, the outer wall of clamping ring 2
It is bonded with 3.1 wall surface of taper hole of inner conical drogue 3, finally tightens the internal thread segment of packing nut 1 and the external screw thread cooperation of main body 5,
Since the inner wall of the left end and packing nut 1 of clamping ring 2 offsets, the outer wall of clamping ring 2 is pasted with 3.1 wall surface of taper hole of inner conical drogue 3
It closes, during packing nut 1 is tightened, the tightening of clamping ring 2 is so as to clamping metal hose；Meanwhile sealing ring 4 is by inner conical drogue 3
The pressing force brought and deform, sealing ring 4 is close to metal hose and forms sealing.
Compared with existing clamp spring connector, the clamping face of the utility model is whole section of the clamping ring 2 coordinated with inner conical drogue 3
Inner wall, and clamping force is big, takes full advantage of the limited clamping space of clamp spring connector.
