[0025] The following will clearly and completely describe the technical solutions of various embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0026] Reference Figure 1-6 An embodiment of the present invention provides a hydraulic hose leak-proof joint, comprising a fixed section 1 and a connecting section 2. The fixed section 1 and the connecting section 2 are connected by a pipeline. The connecting section 2 is used to be connected to the hydraulic hose, and the fixed section 1 is used to be connected to the equipment. The outer wall of the connecting section 2 is connected with a clamping strip 3. Multiple clamping strips 3 are arranged along the circumference of the connecting section 2. The same gap is set between adjacent clamping strips 3. Multiple clamping strips 3 form a reinforcement pipe 4. The inner side of the reinforcement pipe 4 is used to abut against the outer wall of the hydraulic hose. The outer side of the reinforcement pipe 4 is provided with a reinforcement throat clamp 5. The reinforcement throat clamp 5 is used to make the inner side of the reinforcement pipe 4 tightly abut against the outer wall of the hydraulic hose.
[0027] The inner wall of the reinforced throat clamp 5 is provided with a plurality of abutment blocks 10, and a slot 6 is formed between adjacent abutment blocks 10. The slot 6 is used to insert the clamping strip 3. When the reinforced throat clamp 5 is rotated to disengage the clamping strip 3 from the slot 6, the abutment blocks 10 abut against the clamping strip 3 so that the clamping strip 3 presses against the hydraulic hose.
[0028] An anti-slip ring 8 is sleeved on the reinforcing pipe 4, and a one-way connector 7 is provided at one end of the clamping strip 3. The inner wall of the anti-slip ring 8 is provided with an insertion groove for inserting the one-way connector 7. The one-way connector 7 can prevent the anti-slip ring 8 from falling off from the reinforcing pipe 4.
[0029] The one-way connector 7 includes an inserting piece 71 and an anti-slip block 72 . The anti-slip block 72 is provided on the inserting piece 71 . The anti-slip block 72 is provided with a guide surface for inserting the anti-slip ring 8 .
[0030] The one-way connector 7 is made of elastic material. The cross section of the anti-fall-off block 72 is trapezoidal.
[0031] The connecting section 2 is a metal pipe, and a connecting ring for connecting with the clamping strip 3 is fixed on the connecting section 2 .
[0032] The fixing section 1 is a metal connector such as a bolt. The clamping strip 3 is made of an elastic material. The inner side of the clamping strip 3 is provided with grooves 9, which are used to increase the friction between the clamping strip 3 and the hydraulic hose.
[0033] Before use, squeeze the clamping strip 3 so that the reinforcement throat hoop 5 and the anti-slip ring 8 are sleeved on the clamping strip 3 through the guide surface of the anti-slip block 72, and then rotate the reinforcement throat hoop 5 to insert the clamping strip 3 into the clamping groove 6 of the reinforcement throat hoop 5, rotate the anti-slip ring 8 to make the clamping strip 3 located in the insertion groove, and push the reinforcement throat hoop 5 to the appropriate position;
[0034] When the connecting section 2 and the hydraulic hose are fixed in a conventional connection method, the clamping strip 3 is pressed to remove the clamping strip 3 from the clamping groove 6 of the reinforcing throat clamp 5. At this time, the anti-drop ring 8 and the reinforcing throat clamp 5 are removed from the reinforcing pipe 4 to the hydraulic hose. Then, the connecting section 2 is inserted into the hydraulic hose. At this time, the hydraulic hose is located in the gap between the connecting section 2 and the reinforcing pipe 4.
[0035] After fixing the hydraulic hose and the connecting section by conventional connection methods, press the clamping strip 3 to make the clamping strip 3 and the hydraulic hose tight, and then put the reinforcing throat clamp 5 and the anti-slip ring 8 on the clamping strip 3 through the guide surface of the anti-slip block 72, push the reinforcing throat clamp 5 to the larger inner diameter of the connecting section 2, press the clamping strip 3 to disengage from the slot 6, rotate the reinforcing throat clamp 5 to make the abutment block 10 abut the clamping strip 3, and then inject hot melt glue or insert a rubber strip into the slot 6, at this time, make the anti-slip ring 8 abut against the anti-slip block 72, and the anti-slip ring 8 is used to prevent the reinforcing throat clamp 5 from falling off.
[0036] Among them, when fixing with a conventional connection method, a clamp or other fixing part is usually used to fix the hydraulic pipeline to the joint. When the clamp or other fixing part fixes the hydraulic pipeline, the clamp or other fixing part is located between the connecting section 2 and the reinforcing pipe 4.
