Abstract
The utility model discloses a sealed type oil tube connector, which comprises a large-diameter tube and a small-diameter tube. The large-diameter tube is provided with a connecting opening, the small-diameter tube is provided with a connecting head, and the inner diameter of the connecting opening is matched with the outer diameter of the connecting head. The end face of the bottom of the connecting opening is an inclined face, and the end face of the connecting head is an arc face. Due to the fact that the end face of the connecting head is the arc face, and the end face of the bottom of the connecting opening matched with the connecting head is the inclined face, the line contact sealing match of the inclined face and the arc face greatly reduces accuracy requirements of mechanical processing, thereby ensuring the sealing property of the oil tube connecting head and avoiding oil leakage caused by unqualified processing. Therefore, the sealed type oil tube connector has the advantages of being good in sealing, convenient to assemble and the like.
Description
Technical field
The utility model relates to a kind of linkage structure of oil pipe, belongs to the Machining Technology field.
Background technique
As having a lot of oil circuits in the machinery such as boats and ships, land facilities for transport and communication, these oil circuits are made up of various oil pipes, and oil pipe needs to connect in oil circuit.The Placement of existing oil pipe is many; Like thread type, FERRULETYPE, flared type, fastening-pressing type etc., its joint structure generally comprises large-diameter pipe and small-bore pipe, and large-diameter pipe has connection mouth; Small-bore pipe has connecting head; The inwall of connection mouth and the outer wall of connecting head are complementary, and in the oil connection like the thread type connection, the inwall of connection mouth and the outer wall of connecting head have the screw thread that is complementary.In the oil connection of said structure, the end of connecting head is the inclined-plane in addition, and the end face of connection mouth bottom also be the inclined-plane, and the inclined-plane of the end face of inclined-plane bottom connection mouth through the connecting head end compresses the sealing of assurance oil connection mutually.Yet the sealing means of this face contact type is very high to the required precision of machining, if processing request does not reach requirement, is easy to generate the phenomenon of joint leakage of oil.
The model utility content
To above-mentioned situation, the problem that the utility model quasi-solution is determined provides a kind of good airproof performance, sealed type oil connection easy to process.
For achieving the above object; The utility model has adopted following technological scheme: a kind of sealed type oil connection, and it comprises large-diameter pipe and small-bore pipe, said large-diameter pipe has connection mouth; Said small-bore pipe has connecting head; The internal diameter of said connection mouth matches with the external diameter of connecting head, and the end face of said connection mouth bottom is the inclined-plane, and the end face of said connecting head is an arc surface.
The radius of arc of the arc surface of the end face of said connecting head is r, and said connecting head radius is R, then r=0.5R-R.
Adopt such scheme; The sealed type oil connection of the utility model is because the end face of connecting head is an arc surface; And the end face of the connection mouth that is mated bottom is the inclined-plane, and this inclined-plane cooperates with the line contact sealing of arc surface, and the precision that greatly reduces machining is wanted; Thereby can guarantee the sealing of oil connection, eliminate the phenomenon that does not reach the leakage of oil of requirement generation joint because of processing request.Therefore, the sealed type oil connection of the utility model has good airproof performance, characteristics such as easy to process.
Description of drawings
Fig. 1 is the sectional structure chart of the utility model sealed type oil connection.
Among the figure: 1-large-diameter pipe, 2-small-bore pipe, 3-connection mouth, 4-connecting head, the end face of 5-connection mouth bottom, the end face of 6-connecting head.
Embodiment
As shown in Figure 1, the oil connection of the utility model, it comprises large-diameter pipe 1 and small-bore pipe 2; Said large-diameter pipe 1 has connection mouth 3, and said small-bore pipe 2 has connecting head 4, and the internal diameter of said connection mouth 3 matches with the external diameter of connecting head 4; In the oil connection that connects like thread type, the outer wall of the inwall of connection mouth 3 and connecting head 4 has the screw thread that is complementary, and connection mouth 3 and connecting head 4 interconnect through screw thread; Certainly connection mouth 3 is connected also other structure of available existing technology with connecting head 4; Since little with the characteristics degree of association of the utility model, therefore, only do simple the description.
The end face 5 of said connection mouth bottom is the inclined-plane, and the end face 6 of said connecting head is an arc surface.After oil connection connected, connection mouth 3 interconnected with connecting head 4, and the end face 6 of connecting head is pressed on the connection mouth bottom for arc surface end face 5 is the inclined-plane, and its contact is the line contact.
The radius of arc of the arc surface of the end face 6 of said connecting head is r, and said connecting head 4 radiuses are R, then r=0.5R-R.
Claims (2)
1. sealed type oil connection; It comprises large-diameter pipe (1) and small-bore pipe (2); Said large-diameter pipe (1) has connection mouth (3), and said small-bore pipe (2) has connecting head (4), and the internal diameter of said connection mouth (3) matches with the external diameter of connecting head (4); The end face (5) of said connection mouth bottom is the inclined-plane, and the end face (6) that it is characterized in that said connecting head is an arc surface.
2. sealed type oil connection according to claim 1 is characterized in that the radius of arc of arc surface of the end face (6) of said connecting head is r, and said connecting head (4) radius is R, then r=0.5R-R.
