Abstract
The utility model discloses a rubber tube connector for a bursting test machine, which is a tubular structure. One end of the connector is the connecting end of the bursting test machine, and the other end of the connector is the connecting end of a rubber tube. The connecting end of the rubber tube comprises a plurality of connecting sections with different external diameters, and the external diameters of the connecting sections decrease from inside to outside. The rubber tube connector can meet requirements of bursting tests of rubber tubes with various diameters of existing models, reduces frequency of changing the connector in the tests, greatly improves working efficiency, and is free of distortion, leakage and the like.
Description
Technical field
The utility model relates to a kind of testing apparatus, is specially a kind of joint that connects bursting test machine and sebific duct.
Background technique
In automobile making, need use all types of sebific ducts,, like automobile fuel supply line, Brake hose, turn to high-pressure oil pipe etc., therefore need carry out the explosion pressure test to sebific duct continually because of the part sebific duct concerns vehicle safety.
When carrying out bursting test, need bursting test machine and sebific duct be coupled together with joint.Because sebific duct is more and bore differs, generally need to prepare in test the joint of a plurality of different sizes, to satisfy the requirement of test.A kind of sebific duct to be tested of every replacing will be changed the joint that a kind of bore with it matees, and operate cumbersome.And existing joint generally is the hard pipe joint of the product transformation of the way, and after repeatedly use, frequent dismounting, brazing place torsional deformation is prone to cause leakage problems.
Summary of the invention
The utility model provides a kind of bursting test machine rubber hose coupling, satisfies the bursting test of the sebific duct of existing vehicle, has solved existing joint dimension and just can't not satisfy various bore sebific duct tests entirely, needs frequent change, complex operation, problems such as yielding seepage.
A kind of bursting test machine rubber hose coupling is tubular structure, and an end is the testing machine connecting end, and the other end is the sebific duct connecting end; Described sebific duct connecting end comprises the linkage section that some external diameters are different, and the external diameter of described linkage section reduces from inside to outside successively.
Preferably, described testing machine connecting end is provided with outside thread, and size can make joint closely be connected with testing machine according to the testing machine setting.
Preferably, be provided with draw-in groove between described testing machine connecting end and the sebific duct connecting end, convenient wrench operation during installation.
Described sebific duct connecting end comprises the linkage section that some external diameters are different; The external diameter of described linkage section reduces from inside to outside successively, when the sebific duct diameter hour, be connected on the linkage section of outer end and get final product; When the sebific duct diameter is big, as long as be advanced into the suitable linkage section of size.
Preferably, described linkage section is provided with some grooves, to increase the frictional force between sebific duct and the joint, connects more firm.
Preferably, described sebific duct connecting end comprises two sections linkage sections.Near draw-in groove be the heavy caliber linkage section, the outer end be small-bore linkage section.The diameter of existing vehicle sebific duct is 16mm, 38mm, 14mm, 9mm, 7.5mm, 7mm, 5mm, 3mm etc., more preferably, the external diameter of the heavy caliber linkage section of joint is made as 38mm, and the external diameter of small-bore linkage section is made as 15mm; Or the external diameter of heavy caliber linkage section is made as 7mm, and the external diameter of small-bore linkage section is made as 3.5mm, only need possess the joint of these two kinds of sizes, can satisfy the needs of all size sebific ducts tests basically.
The utility model joint can satisfy the bursting test of the existing various bore sebific ducts of vehicle, has reduced the number of times of changing joint in the test, increases work efficiency greatly, and problems such as torsional deformation, seepage can not occur.
Description of drawings
Fig. 1 is the structural representation of the utility model joint.
Wherein, 1-testing machine connecting end; 2-sebific duct connecting end; 3-heavy caliber linkage section; The small-bore linkage section of 4-; The 5-draw-in groove.
Embodiment
As shown in Figure 1, a kind of bursting test machine rubber hose coupling is tubular structure, and an end is a testing machine connecting end 1, and the other end is a sebific duct connecting end 2.Testing machine connecting end 1 is provided with the outside thread that is complementary with testing machine.Be provided with draw-in groove 5 between testing machine connecting end 1 and the sebific duct connecting end 2.Sebific duct connecting end 2 comprises two sections linkage sections that external diameter is different, and the external diameter of linkage section reduces from inside to outside successively, and linkage section is provided with some grooves, to increase the frictional force between sebific duct and the joint.Near draw-in groove 5 be heavy caliber linkage section 3, the outer end be small-bore linkage section 4, heavy caliber linkage section 3 external diameters are 38mm, the external diameter of small-bore linkage section 4 is 15mm.
A kind of bursting test machine rubber hose coupling, structure is identical with embodiment 1, and different is, and the external diameter of heavy caliber linkage section 3 is 7mm, and the external diameter of small-bore linkage section 4 is 3.5mm.
During application, testing machine connecting end 1 is threaded with testing machine, selects to be installed on the different linkage sections of sebific duct connecting end 2 according to the bore of sebific duct again and get final product, without the frequent change joint.
