[0002] A breaker hammer, also known as a hydraulic breaker, hydraulic pick, hydraulic gun, etc., is an important auxiliary working tool of an excavator or loader. It uses the pressure oil provided by the pump station of the excavator or loader as power to drive the piston to reciprocate. During the piston stroke, the high-speed impact of the drill rod is used to break the ore, concrete and other solids. It is often used in mountain opening, road breaking, house demolition, bridge demolition, and mining of mines and ore.

[0003] In the use of the breaker hammer, a pipeline is required to supply pressure oil provided by an excavator or loader pump station. The pressure oil serves as a power source to drive the piston inside the breaker hammer to reciprocate, thereby achieving the function of high-speed impact on the drill rod and crushing solids such as ore and concrete. In the connection of the pipeline, an integrated joint is required. The existing joint is generally an ordinary joint core tube, which can be installed by putting one end of the pipeline on the joint core tube. However, in use, the breaker hammer is prone to cracking, leakage, etc. in the joint core tube and the pipeline connection position due to its special high pulse and high-intensity vibration, resulting in a high failure rate and a short service life. Therefore, the present invention proposes a new connection structure of a breaker hammer pipeline integrated joint to solve the problems existing in the prior art. Summary of the invention

[0027] Embodiment 1

[0028] according to Figure 1 , 2 As shown in Figures 3, 4, 5 and 6, this embodiment proposes a novel connection structure of a breaker pipe integrated joint, comprising a core pipe 1 and an outer sleeve 2, wherein the outer sleeve 2 is sleeved on the outer side of the core pipe 1, and a slope angle pipe 3 is provided at the left end of the outer sleeve 2, and a connecting pipe 4 is connected to the left end of the slope angle pipe 3, and the connecting pipe 4 is threadedly adapted to the left end of the outer side of the core pipe 1;

[0029] An axial foot 5 is provided at the right end of the outer side of the outer sleeve 2, and the axial foot 5 is provided in at least three groups at equal angles around the center of the outer sleeve 2. An inclined rod 6 is rotatably provided on the inner side of the axial foot 5, and a holding leg 7 is provided at the right end of the inclined rod 6. A rotating ring 8 is threadedly installed at the left end of the outer side of the outer sleeve 2, and an extrusion ring 9 is provided at the right end of the outer side of the rotating ring 8. The extrusion ring 9 is used to squeeze the inner side of the inclined rod 6. When in use, it is composed of a core connecting tube 1 and an outer sleeve 2, and the pipeline interface is sleeved on the core connecting tube 1 from the right end. The outer sleeve 2 is rotated and moved to the right end to be sleeved on the outside of the pipeline interface through the threaded adaptation of the connecting tube 4 and the outer side of the core connecting tube 1, and is pressed on the pipeline interface by the inner slope of the slope angle tube 3, so as to clamp and fix the pipeline interface, and the rotating ring 8 is rotated synchronously and moved to the right end on the outer sleeve 2 through the threaded action, so that the extrusion ring 9 is pressed on the inner left end of the inclined rod 6, and the holding leg 7 is rotated to the lower right end, thereby clamping the pipeline, further reinforcing the pipeline, and avoiding cracks, leakage and the like at the pipeline connection position.

[0030] The right end of the core connection tube 1 is provided with a bevel opening 10, and the right end of the outer side of the core connection tube 1 is provided with an anti-skid protrusion 11, and the anti-skid protrusion 11 is provided with multiple groups of equidistant groups. When in use, the pipeline joint is sleeved onto the core connection tube from the right end through the bevel opening 10, and the friction between the pipeline and the inner side is increased by the anti-skid protrusion 11, so that the pipeline is more tightly connected to the core connection tube 1.

[0031] The left end of the core connection tube 1 is provided with a stop ring 12, and the stop ring 12 is integrally formed with the core connection tube 1. The outer side of the core connection tube 1 between the stop ring 12 and the anti-slip protrusion 11 is provided with an external thread 13, and the inner side of the connecting tube 4 is provided with an internal thread 14, and the internal thread 14 is adapted to the external thread 13.

When disassembling, it is only necessary to rotate the rotating ring 8 to reset the extrusion ring 9, and the diagonal rod 6 can be rotated and reset under the action of the torsion spring 22 to open the pressing leg 7, and then the connecting pipe 4 is rotated to reset the outer sleeve 2 to the left end, and the fixation of the slope angle tube 3 to the pipeline interface can be released, and the disassembly is more convenient.

[0035] The outer left end of the outer sleeve 2 is provided with an outer screw groove 18, the inner side of the rotating ring 8 is provided with an inner screw thread, the inner screw thread is threadedly adapted to the outer screw groove 18, and the outer side of the rotating ring 8 is provided with an anti-slip convex surface. When in use, since the inner screw thread is threadedly adapted to the outer screw groove 18, the rotating ring 8 is rotated through the anti-slip convex surface, and moves to the right end on the outer sleeve 2 through the action of the thread, so that the extrusion ring 9 is pressed on the inner left end of the inclined rod 6, and the pressing leg 7 is rotated to the lower right end, thereby clamping the pipeline, further reinforcing the pipeline, and avoiding cracking, leakage, etc. at the pipeline connection position.
