Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Example 1

As shown in fig. 1-2, the present embodiment provides a hose connector for a hydraulic system, including a connector main body 1, a clamping hoop 8 and a sleeve 9, the connector main body 1 includes an inlet end sleeve head 2 and an output end sleeve head 3, the inlet end sleeve head 2 is connected to the output end sleeve head 3 through a bending body 4, and the inlet end sleeve head 2 is communicated with the output end sleeve head 3 through a hollow liquid circulation hole 5, the output end sleeve head 3 includes a straight pipe section 6, a first blocking portion 7 is arranged between the straight pipe section 6 and the bending body 4, the clamping hoop 8 is in threaded connection with the straight pipe section 6, and the sleeve 9 is sleeved on the clamping hoop 8 and is in threaded connection with the clamping hoop 8.

The included angle formed between the central axis of the inlet end sleeve head 2 and the central axis of the outlet end sleeve head 3 is any angle between 105 degrees and 130 degrees, and the outlet end sleeve head 3, the clamping hoop 8 and the sleeve 9 are coaxially arranged.

The access end sleeve head 2 comprises a second blocking part 202, a first connecting part 201, a limiting groove 204 and a first inclined pipe section 203, the first connecting part 201 and the first inclined pipe section 203 are sequentially fixed at one end of the bending body 4, the limiting groove 204 is arranged between the first inclined pipe section 203 and the first connecting part 201, and the part of the bending body 4 larger than the first connecting part 201 forms the second blocking part 202.

The straight tube section 6 is fixed at the other end of the bending body 4, a first blocking part 7 is formed at the end part of the bending body 4 with the external diameter being redundant of the straight tube section 6, and one side end face of the clamping hoop 8 is attached to the first blocking part 7.
