Abstract
The utility model provides a fast self-locking joint for pressure oil pipe, as long as an oil pipe is sheathed on a hollow rivet pipe threaded bolt with a certain taper, then an oil pipe lock nut is tightened to lock the oil pipe. The utility model is characterized in that one end of a rivet nut 1 is matched with the bellmouth of one end of a hollow rivet pipe threaded bolt 2 whose the other end is accompanied with a conical surface; one end of an oil pipe lock nut 3 is provided with a closely-pitched inside thread which is matched with the hollow rivet pipe threaded bolt 2, and the other end is provided with an inner conical surface which is matched with the outer conical surface of the hollow rivet pipe threaded bolt 2.
Description
The utility model belongs to piecing devices, is the fast automatic lock-on connection of a kind of high-pressure oil pipe specifically.
The domestic oil pipe that uses in the hydraulic system on engineering machinery has two kinds of patterns at present, and a kind of is to be connected with interface with hollow bolt; Another kind is to connect with riveting pipe nut.Though the Placement of these two kinds of patterns is different, but joint is identical with the Placement of oil pipe, that is to say that oil pipe normally fixedlys connected with joint.We know, rubber oil hose in use all situations can occur, because of oil pipe and oil connection can only disposablely use, so when needing to change oil pipe, simultaneously also need to change oil connection, concerning the user, can bring all inconvenience like this, and must be to special factory, with special purpose machine tool processing, particularly this problem is particularly outstanding on some imported mechanicals.At present, particularly in the traffic engineering construction, imported mechanical is a lot, not only price is very high to change an oil pipe, and often influences construction speed because of order time is long, sometimes because of also join a period of time wide in variety less than, will directly have influence on the use of machinery like this, also cause waste simultaneously.
The purpose of this utility model then is the problem at above-mentioned existence, provides a kind of as long as oil pipe is enclosed within on the hollow riveting pipe bolt that has certain taper, and tightening the oil pipe lock nut then can be with the fast automatic lock-on connection of high-pressure oil pipe of oil pipe locking.
Technical solution of the present utility model:
A kind of fast automatic lock-on connection of forming by riveting pipe nut of high-pressure oil pipe, it is characterized in that riveting pipe nut 1 one ends match with the horn mouth of hollow riveting pipe bolt 2 one ends, the hollow riveting pipe bolt the other end has the conical surface, the closely-pitched internal thread that oil pipe lock nut 3 one ends are provided with matches with hollow riveting pipe bolt 2, and the inner conical surface that the other end is provided with matches with hollow riveting pipe bolt 2 male cone (strobilus masculinus)s.
Advantage of the present utility model is as follows:
1. convenient and reliable: as no matter to be that the needs which kind of reason causes are changed oil pipe, only need to select for use the oil pipe of certain specification certain-length to be connected and tighten that oil connection is connected with the institute interface matched and gets final product then with this joint.Because being connected between oil pipe and the joint is to adopt bipyramid face screw thread to screw, and can guarantee its sealing and soundness completely, changes oil pipe like this and just seems convenient and reliable naturally.
2. saving saves time: because the engineering construction duration is generally all tighter, when needing to change oil pipe, will change immediately, yet most import equipment oil pipe all needs order in advance, because wide in variety, the price height certainly will cause and overstock waste.Use this oil connection, not only can change at any time, and need only be equipped with each homemade specification oil pipe and get final product, so both striven for construction speed, saved cost (because of joint can repeatedly use) again.
3. but producing in serial form, seriation are supporting: the oil pipe on the engineering machinery has plurality of specifications, and the oil connection size can form producing in serial form according to hydraulic oil pipe various sizes size.
Fig. 1 is the utility model schematic representation.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model is by riveting pipe nut 1, hollow riveting pipe bolt 2, oil pipe lock nut 3 is formed, 1 its effect of riveting pipe nut is to be connected with oil-collecting hole, hollow riveting pipe bolt 2 is main bodys, play the middle effect that oil pipe is connected with oil-collecting hole, hollow riveting pipe bolt 2 is processed with hexagon nut at the end near the riveting mouth of pipe, is convenient to use in installation.Connecting between riveting pipe nut 1 and the hollow riveting pipe bolt 2 is such: an end of hollow riveting pipe bolt 2 has horn mouth, the other end is the hollow bolt that has the conical surface, have a bell-mouthed end and riveting pipe nut 1 one ends are stuck between horn mouth and the hexagon nut loosely by impacting force, though at this moment riveting pipe nut 1 can rotate, but it becomes inseparable one with hollow riveting pipe bolt 2, and riveting pipe nut 1 the other end is processed into coarse-pitch thread and is connected with oil connection.Oil pipe lock nut 3 structure internally sees that an end is processed into the closely-pitched internal thread, matches with hollow riveting pipe bolt 2, and the other end is processed into inner conical surface, matches with hollow riveting pipe bolt 2 male cone (strobilus masculinus)s, and intermediate portion is processed into pipe thread, in order that the locking oil pipe; From the outside, the conical surface is processed at two ends, and intermediate portion is processed into hex surface, is convenient to screw oil pipe.When tightening oil pipe lock nut 3, oil pipe lock nut 3 just moves forward a segment distance, oil pipe is to be enclosed within the end that hollow riveting pipe bolt 2 has tapering, and the gap between hollow riveting pipe bolt 2 and the oil pipe lock nut 3 is then more and more littler, until oil pipe is locked tightly.
