The utility model relates to a high efficiency pressure pipe junction with quick-clamping function, which is composed of a join body communicated with pipelines, a valve base, a valve core, a link rod realizing the function of clamping copper pipe, a spanner, a joint base, a clamping element, a regulating nut, a locking nut, etc. The utility model makes use of an eccentric spanner to drive a clamping element to make the clamping element push and shrink inwards to reach the goal of one time quick-clamping. The utility model has compact structure, the pressure resistance can normally adapt and satisfy 25-30 kg operating requirement, it can also clamp the copper pipe with poor manufacturability and form error, and it can be regulated according to the size of the pipe diameter. The utility model has larger flexibility, it can reduce the consuming cost greatly, and it can raise the qualified rate of the product assembly and reduce the labor intensity of workers.

Description

High efficiency pressure pipe junction with quick-clamping function

The utility model relates to used quick clamping tool on the product Assembly lines such as quick clamping tool, particularly refrigerator in the chiller plant industry, air condition compressor, vaporizer.

In the chiller plant industry, the product assembling needs pressure testing, leak test, vacuumizes, pours into fluorine Lyons etc., carry out bound need the on the Assembly line of these operations with connecting clamping tool fast, and existing used jointing, basically all be to reach by screw thread rotation to connect the purpose of connecting, the labor strength height, efficient is low, big as the copper pipe error, clamping force can't be regulated and often be pressed from both sides not tight.

Task of the present utility model is at the existing deficiency that can't clamp fast of existing joint, alleviates labor strength for society provides a kind of, raises the efficiency, adjustable efficient withstand voltage quick gripping tube fitting.

The utility model has following accompanying drawing.

Embodiment is described in detail below in conjunction with accompanying drawing.

With reference to Fig. 1～Fig. 3: the efficient withstand voltage quick gripping tube fitting of the utility model, it utilizes eccentric structure to promote moving of clamping element, and shrinks to the center and to reach the purpose that clamps copper pipe.

Adorning valve seat (4) in the connected body (5), adorning the spool (3) that has seal ring (1) and spring (2) in the seat, it is the only way which must be passed of connecting source of the gas, liquid source, can open passage by pressure spring (2) after spool (3) is subjected to certain pressure.Connected body (5) links to each other with connecting rod (6) with taper pipe thread, connecting rod (6) is the hollow tubular element, its the other end and joint chair (9) sliding connection, joint chair (9) (Fig. 5, Fig. 6) left end fluting (20), can hold the connection between connecting rod (6) and the spanner (8), the fork wrench (8) that has eccentric structure is stuck in connecting rod (6) neck both sides, be connected with joint chair (9) both sides by screw (7), spanner (8) is that rotating shaft can be done the certain limit rotation motion with screw (7), the omoplate (15) that can promote link (6) when making spanner (8) go to imaginary line position among the figure pushes away it to the right, and spanner (8) aperture (18) must meet the condition (Fig. 4) of H＞L to the distance of end face (19).Joint chair disposes clamping element in (9), the outer adjusting nut (12) that is disposing locking nut (10) and having the circular cone aperture of joint chair (9).

Clamping element among one of embodiment is made up of deformable seal circle (11), ring folder (13), steel ball (14), and the tapered segment of ring folder (13) has 6～8 uniform apertures, and steel ball (14) is housed in each hole.When spanner (8) forwards the imaginary line position to by solid line position is widely different, spanner (8) end face (19) presses connecting rod (6) omoplate (15) to be made it the right side and pushes away, at this moment deformable seal circle (11) is out of shape by compression in joint chair (9) and oppresses ring folder (13) and pushes away on the right side simultaneously, under the effect in adjusting nut (12) circular cone aperture, contraction is the disposable copper pipe of clamping towards the center simultaneously to be distributed on the steel ball (14) that encircles in folder (13) aperture, loosen as needs, as long as cocked spanner (8), copper pipe can break away from.According to copper pipe diameter and pressure size variation, can regulate the aperture size by adjusting nut (12), 0.1～0.6 millimeter of caliber regulated quantity, compression resistance can reach more than the 45kg, and it is constant by locking nut (10) pinning port size to be stablized again after regulating.Because the function that distortion is shunk behind deformable seal circle (11) pressurized, the copper pipe that makes some have form error and end face burr can clamp equally, and this embodiment can also clamp the enlarging copper pipe.

Embodiment's two clamping element is made up of deformable seal circle (11) and chuck (16), have 3～5 elastic grooves (17) on the chuck (16), because the effect of chuck (6) end face conical surface and adjusting nut (12) conical bore, be subjected to the chuck (6) that the right side pushes away and play the effect that clamps copper pipe equally, 0.1～0.4 millimeter of caliber regulated quantity, compression resistance can reach 25～35kg, and this embodiment can clamp straight tube.

Above embodiment can be made various different sizes to adapt to the clamping needs of different tube diameters.The cone angle that makes joint chair (9) conical bore during manufacturing more helps clamping suitably greater than the cone angle of the conical surface that encircles folder (13) and chuck (16).

According to the high efficiency pressure pipe junction with quick-clamping function of the utility model design, utilize decenter clutch to promote to clamp the purpose that element pushes away its right side and inwardly contraction reaches clamping copper pipe. Structure compactness, weight are light, can realize disposable quick clamping, anti-pressure energy adapts to the normality that satisfies 25～30kg and uses requirement, relatively poor copper Guan Yineng with shape error clamps to some technologies, and can regulate according to the caliber size, so flexibility is bigger, can reduce consuming cost, improve the assembling product qualification rate, alleviate workman's labour intensity.
