Detailed Description

The utility model is further described below with reference to the drawings and examples.

As shown in fig. 1 and 2, an embodiment of the manual compression pipe device comprises a cylinder barrel 3, wherein the rear end of the cylinder barrel 3 is connected with an air supply joint 1, an outer pipe thread 2 is processed on the outer side of the air supply joint 1, and the outer pipe thread 2 is matched with an inner pipe thread 4 on the cylinder barrel 3 to realize detachable connection between the air supply joint 1 and the cylinder barrel 3. The front end of the cylinder barrel 3 is fixedly connected with a cylinder barrel 8 with a cylinder barrel cavity 9 at the center. A cylinder piston 6 is arranged in a cylinder cavity 5 of the cylinder barrel 3, and the cylinder piston 6 is fixedly connected with a cylinder piston rod 7 with the front end penetrating into a cylinder cavity 9 of the cylinder barrel. The cylinder barrel 3 is provided with an exhaust hole 32 positioned in front of the cylinder piston 6.

Further, a one-way valve is arranged in the air supply connector 1, and air can be supplied from outside to inside only, so that pressure is maintained reversely.

The cylinder barrel 8 is slidably provided with a first piston rod 10, a second piston rod 11, a third piston rod 12 and a fourth piston rod 13 which can extend and retract from the cylinder barrel 8 and serve as cylinder piston rods.

The front side of the cylinder barrel 8 of the oil cylinder is fixedly connected with a rocker supporting seat 18. The rocker supporting seat 18 is provided with a left hinge support, an upper hinge support, a right hinge support and a lower hinge support, and the four hinge supports are correspondingly connected with the first rocker 14, the second rocker 15, the third rocker 16 and the fourth rocker 17 through a first rocker pin 19, a second rocker pin 20, a third rocker pin 21 and a fourth rocker pin 22 respectively. The rear ends of the first rocker 14, the second rocker 15, the third rocker 16 and the fourth rocker 17 are respectively contacted with the outer ends of the first piston rod 10, the second piston rod 11, the third piston rod 12 and the fourth piston rod 13, and the front ends are respectively correspondingly connected with a first extrusion head 27, a second extrusion head 28, a third extrusion head 29 and a fourth extrusion head 30 through a first extrusion head pin 23, a second extrusion head pin 24, a third extrusion head pin 25 and a fourth extrusion head pin 26.

The inner sides of the first extrusion head 27, the second extrusion head 28, the third extrusion head 29 and the fourth extrusion head 30 are respectively provided with an anti-slip groove 31 in the form of a wave protrusion. The anti-slip groove 31 is used for limiting the mutual sliding displacement of the pipe fitting and the pressing head when the pressing head presses the pipe fitting.

Further, the inner side surfaces of the first extrusion head 27, the second extrusion head 28, the third extrusion head 29 and the fourth extrusion head 30 are concave cambered surfaces. Because the compression amount of the oil pipe joint is small, the pressing work of the oil pipe joint is completed after a trace is slightly pressed on the oil pipe joint. Therefore, the pressing operation of the oil pipe joint can be realized if the inner side surfaces of the four extrusion heads are plane, but the effect is better if the concave cambered surface is adopted.

In use, an inflation tube (such as the inflation head of a manual inflator) is connected to the air supply connector 1 and supplied with air, and the air enters the cylinder barrel 3 through the air supply connector 1. Under the pushing action of the gas, the cylinder piston 6 and the cylinder piston rod 7 together press the hydraulic oil in the cylinder barrel cavity 9 of the oil cylinder forwards. The gas around the cylinder rod 7 is discharged into the air through the gas discharge hole 32.

Because the sectional area of the cylinder piston 6 is far larger than that of the cylinder piston rod 7, the pressure of hydraulic oil in the cylinder cavity 9 of the cylinder is tens or hundreds of times of the input air pressure of the manual inflator, thereby ensuring the buckling capacity.

The hydraulic oil in the cylinder cavity 9 drives the first piston rod 10, the second piston rod 11, the third piston rod 12 and the fourth piston rod 13 to extend out of the cylinder 8 in the left, upper, right and lower directions respectively, so as to push the first rocker 14, the second rocker 15, the third rocker 16 and the fourth rocker 17 to swing around the rocker supporting seat 18 respectively. The front ends of the first rocker 14, the second rocker 15, the third rocker 16 and the fourth rocker 17 respectively drive the first extrusion head 27, the second extrusion head 28, the third extrusion head 29 and the fourth extrusion head 30 to inwards act on the joint extrusion oil pipe joint, so that the pressing work of the oil pipe joint is completed.

After the oil pipe joint pressing work is completed, the air supply joint 1 is disassembled, the first extrusion head 27, the second extrusion head 28, the third extrusion head 29 and the fourth extrusion head 30 are pushed outwards by hands, and after the first extrusion head, the second extrusion head, the third extrusion head and the fourth extrusion head are reset, the air supply joint 1 is mounted on the cylinder barrel 3, and the next necking and buckling work is prepared.
