Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the connector of the present embodiment includes a main body 1, two first connecting portions 2, and a second connecting portion 5.
The second connecting portion 5 is a connecting hole provided in the main body portion 1.
The main body 1 is provided with a first fluid channel 101.
The two first connecting parts 2 are respectively arranged at two ends of the main body part 1, the two first connecting parts 2 are respectively provided with a second fluid channel 204 communicated with the first fluid channel 101, the first fluid channel 101 and the two second fluid channels 204 are coaxially arranged, the two first connecting parts 2 respectively comprise a first section 201, a second section 202 and a third section 203, the first section 201, the second section 202 and the third section 203 are sequentially distributed along the axial direction of the first connecting part 2, the two first sections 201 are far away from the main body part 1, the two first sections 201 are respectively provided with an interface connected with a metal hose, the two third sections 203 are close to the main body part 1, the two second sections 202 are respectively positioned between the first sections 201 and the third sections 203, and the outer diameters of the two first sections 201 and the two third sections 203 are gradually increased from one end far away from the main body part 1 to one end close to the main body part 1, the two second sections 202 are both cylindrical, and a plurality of axially spaced barb structures 2021 are disposed on the two second sections 202.
The main body part 1 is provided with two pressing mechanisms which are respectively used for pressing and fixing the metal hoses sleeved on the two first connecting parts 2, so that after the metal hoses are sleeved on the first connecting parts 2, the metal hoses can be pressed and fixed by the pressing mechanisms, and the metal hoses can be better prevented from slipping off from the first connecting parts 2.
Every hold-down mechanism all includes a depression bar 3 and a torsion spring 4, and the rotatable setting of depression bar 3 is on main part 1, and torsion spring 4 cover is put in the rotation junction of depression bar 3, and the one end of torsion spring 4 is fixed with depression bar 3, and the other end and the main part 1 of torsion spring 4 are fixed.
When depression bar 3 is in free state, the working end of depression bar 3 compresses tightly on first connecting portion 2, when pressing depression bar 3 and making depression bar 3 be in the state of pressing, first connecting portion 2 is kept away from to the working end of depression bar 3, thus, when needs put the metal collapsible tube cover on first connecting portion 2, press depression bar 3 earlier and make the working end of depression bar 3 keep away from first connecting portion 2, then cup joint the metal collapsible tube on first connecting portion 2, then loosen depression bar 3, make the working end of depression bar 3 compress tightly metal collapsible tube on first connecting portion 2, thereby can prevent metal collapsible tube slippage from first connecting portion 2.
