Abstract
The utility model relates to a connecting structure of a high-pressure oil pipe. The connecting structure of the high-pressure oil pipe comprises an oil pipe and a connector. A clamp nut and a lining are arranged at the position of the connector, and the lining is arranged on the shoulder portion of connecting position of the connector, and the oil pipe and is located between the clamp nut and the connector. The connecting end face of the connector is arc-shaped. Due to the fact that the connecting end face of the connector is designed to be arc-shaped, the connector is enabled to be matched with the shapes of an oil injection nozzle and a connector of a oil injection pump when the connector is connected with the oil injection nozzle and the oil injection pump,and connecting reliability is greatly improved. The connecting structure of the high-pressure oil pipe has the advantages of being reliable in connecting and good in compression-resistance and shock-resistance properties.
Description
Technical field
The utility model relates to a kind of high-pressure oil pipe, specifically a kind of linkage structure of high-pressure oil pipe.
Background technique
High-pressure oil pipe generally is used for connecting internal combustion (IC) engine oil-jetting pump and oil nozzle, high-pressure oil pipe need to bear frequently shock and vibration when work, therefore the antivibration that is connected with Injection Pump of high-pressure oil pipe and oil nozzle, resistance to compression and sealing are the important indicators of the quality of check high-pressure oil pipe, when being connected with Injection Pump with oil nozzle owing to high-pressure oil pipe at present, connecting head presents round platform and forms, connecting head contacts with Injection Pump with oil nozzle and is very face contact of line contact, the less easy wearing and tearing of this Placement contact, antivibration and anti-pressure ability are limited, sealing is destroyed easily, cause connection unreliable, affect the normal operation of machine.
The model utility content
The purpose of this utility model is to provide a kind of linkage structure of high-pressure oil pipe, the connecting end surface of connecting head is designed to arc, so that connecting head is when being connected with Injection Pump with oil nozzle and the form fit of oil nozzle and Injection Pump interface, the reliability that connects promotes, have and connect reliably the characteristics that resistance to compression and resistance to shock are good.
For achieving the above object by the following technical solutions:
A kind of linkage structure of high-pressure oil pipe comprises oil pipe and connecting head, also is provided with tightening nut and lining at connector position, it is characterized in that: lining be arranged on the shoulder of connecting head and oil pipe joint and be in tightening nut and connecting head between; The connecting end surface of described connecting head is curved.
The utility model is designed to arc with the connecting end surface of connecting head, and lining is arranged on the shoulder of connecting head and oil pipe joint and be in tightening nut and connecting head between; Area of contact when this structural design can increase high-pressure oil pipe and connects improves the reliability that connects, convenient and assurance sealing when the lining shoulder that is arranged on connecting head and oil pipe joint is installed in addition.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of linkage structure of high-pressure oil pipe comprises oil pipe 1 and connecting head 2, also is provided with tightening nut 3 and lining 4 at connecting head 2 places, lining 4 be arranged on the shoulder of connecting head 2 and oil pipe 1 joint and be in tightening nut 3 and connecting head 2 between; The connecting end surface 21 of described connecting head 2 is curved.
Adjust first the position of lining on oil pipe when the utility model is installed, so that the lining outer end flushes with the screw thread of nut, and smears lubricating grease at sleeve outer surface, connecting head and screw thread, has installed at the scene of getting final product, very easy to use.
The utility model is designed to arc with the connecting end surface of connecting head, so that connecting head is when being connected with Injection Pump with oil nozzle and the form fit of oil nozzle and Injection Pump interface, when connecting, high-pressure oil pipe can increase the area of contact of connecting head and oil nozzle and Injection Pump, promote resistance to compression and resistance to shock that high-pressure oil pipe connects, and guarantee the reliability of sealing.
