Technical field

The present invention relates to a kind of pressing rubber tube joint locating piece and its withhold localization method.

Background technique

Currently, using large-bore hose under hyperbaric environment with the development of the engineering constructions such as ocean, mining and subway Situation is more and more, and demand of the market to large-bore hose also gradually increases.Large-bore hose connector in the production process, needs Sleeve is withheld on tube core, then sebific duct is inserted between tube core and sleeve, so that sleeve can consolidate sebific duct It is scheduled on tube core.But sleeve is when being set on tube core, due between sleeve and tube core there are the length of gap and sleeve compared with It grows, while sleeve, under the gravity of its own, so that sleeve and tube core are easy to during withholding, generation is eccentric to be showed As not on same axis, later period sebific duct can not be inserted between tube core and sleeve i.e. sleeve and tube core, and then can be generated big The defective products of amount, leads to that the production cost increases, causes unnecessary loss.

To sum up, it is necessory to provide the new pressing rubber tube joint locating piece of one kind and its withhold localization method.

Summary of the invention

Technical problem to be solved by the invention is to provide a kind of pressing rubber tube joint locating piece and its withhold localization method.

In order to solve the above technical problems, the present invention provides: a kind of pressing rubber tube joint locating piece is set to tube core and set On cylinder, the tube core passes through the inside of the sleeve, and the tube core includes first end, the pressing rubber tube joint locating piece packet Positioning region is included, the first end is contained in the positioning region and the outer circumference surface of the first end acts against positioning region In inner radial surface, the positioning region is contained in the sleeve and the radially-outer surface of the positioning region acts against the sleeve Inner radial surface on.

The beneficial effects of the present invention are: pressing rubber tube joint locating piece of the present invention and its withholds localization method and pass through in pipe Increase a positioning region between core and sleeve, thereby may be ensured that and sleeve is being withheld into guarantee sleeve and tube core beginning when on tube core Eventually on the same axis, sleeve will not be made to deviate radially with tube core, prevents sleeve and tube core from eccentric phenomena occur, in turn Sebific duct can be smoothly inserted between the tube core and sleeve after withholding, and reduce bad product rate, and do not need after withholding Tube core and sleeve portion are proofreaded, production efficiency is improved.

Detailed description of the invention

Fig. 1 is the sectional view of pressing rubber tube joint locating piece of the present invention.

Specific embodiment

With reference to the accompanying drawing to pressing rubber tube joint locating piece of the present invention and its withhold localization method make it is clear and complete Explanation.

As shown in Figure 1, the pressing rubber tube joint locating piece 3 is set between tube core 1 and sleeve 2 comprising positioning region 31 and the grip part 32 that is set on the positioning region 31.

As shown in Figure 1, the tube core 1 includes first end 11 and is set to far from the position on 11 direction of first end In the annular groove 12 on its outer circumference surface.The sleeve 2 include setting corresponding with the annular groove 12 attaching part 21 and with The second end 22 of the corresponding setting of the first end 11, the attaching part of the first end 11 of the tube core 1 from the sleeve 2 21 pass through the inside of the sleeve 2, and the annular groove 12 is from the outer circumference surface of the tube core 1 radially to the tube core 1 Central axis is recessed to be formed, and before withholding, the diameter of 12 inner peripheral surface of annular groove is less than the straight of 1 outer circumference surface of tube core Diameter, the diameter of 1 outer circumference surface of tube core are less than the diameter for withholding preceding 21 inner peripheral surface of attaching part, and the attaching part 21 is detained It is pressed in the annular groove 12.

As shown in Figure 1, the positioning region 31 is cylindrical body, one end of the positioning region 31 is equipped with opening, the positioning region 31 can also be at least three support rods for disconnecting setting in a circumferential direction, to rise to first end 11 and the second end 22 It is acted on to firm positioning support, prevents its bias.The first end 11 is contained in the positioning region 31, the first end The outer circumference surface in portion 11 acts against in the inner radial surface of the positioning region 31, and the positioning region 31 is contained in the sleeve 2 In the second end 22, the radially-outer surface of the positioning region 31 is acted against in the inner radial surface of the sleeve 2.Before withholding, institute The outer circumference surface for stating tube core 1 acts against in the inner radial surface of positioning region 31 and the radially-outer surface of positioning region 31 acts against sleeve In the inner radial surface of 2 the second end 22, and the diameter of 21 inner radial surface of attaching part is greater than 12 inner peripheral surface of annular groove Diameter so that there are gaps between attaching part 21 and annular groove 12, after withholding, the attaching part 21 is withheld in annular groove In 12, i.e., 21 inner radial surface of attaching part diameter reduce, while first end 11, positioning region 31, the second end 22 diameter It is constant, thereby may be ensured that sleeve 2 and tube core 1 always in same axis A-A ' on, it prevents during withholding due to button Tube core 1 caused by pressing and 2 eccentric phenomena of sleeve reduce production cost so as to reduce product defect rate.It is finished withholding Afterwards, positioning region 31 can be extracted out by holding grip part 32.The grip part 32 is welded with the positioning region 31, the grip part 32 It can be and be wholely set with the positioning region 31, can also connect by other means.This creation is applicable not only to heavy caliber glue Pipe, is also applied for plain bore sebific duct.

A kind of pressing rubber tube joint localization method of the present invention, it is described for withholding sleeve 2 in the tube core 1 Tube core 1 includes the annular groove 12 for being located at the first end 11 of one end and being set on 1 outer circumference surface of tube core, the sleeve 2 include the attaching part 21 opposite with annular groove 12 and the second end 22 opposite with the first end 11, the rubber hose coupling Withholding localization method further includes a pressing rubber tube joint locating piece, and the pressing rubber tube joint locating piece includes positioning region and setting Grip part on the positioning region, the pressing rubber tube joint localization method the following steps are included:

Step 1: firstly, tube core 1 is passed through to the inside of sleeve 2, and the attaching part 21 of sleeve 2 is directed at the annular groove 12, There are gaps between the attaching part 21 and annular groove 12；

Step 2: then, the first end 11 of tube core 1 is contained in positioning region 22, and the outer circumference surface of tube core 1 abuts against In the inner radial surface of positioning region 31, the positioning region 31 is contained in the second end 22, and the diameter of the positioning region 31 is outside Surface acts against in the inner radial surface of sleeve 2, and the tube core 1 is on same central axis with the sleeve 2 at this time；

Step 3: and then withhold the attaching part 21 of sleeve 2 in the annular groove 12 of tube core 1, then positioning region 31 is taken Under；

Step 4: terminate.

Above-mentioned technical proposal is only the explanation to the embodiment of the present invention, not limitation of the present invention, all art technologies The equivalent variation that personnel's creation according to the present invention is carried out belongs to protection scope of the present invention.
