Description

Technical Field

[0001] This utility model relates to the field of four-way technology, specifically to a four-way connector for oil pipe heads. Background Technology

[0002] The hydraulic mechanism includes an oil supply device, hoses, and actuators. Hydraulic oil is delivered to the actuators via hoses, and the hoses and the oil supply device are connected via a four-way connector. The existing four-way connector has four ports arranged in a cross shape, with the included angle between every two ports fixed at 90°.

[0003] A search revealed a Chinese utility model patent with publication number CN218178235U, which discloses an adjustable-angle four-way oil pipe head. According to its description, the angle between the oil pipe connector and the four-way oil pipe head body is adjustable through the cooperation of the rotating bracket and the mounting bracket. When the hoses are not perpendicular, the rotating bracket is controlled to rotate inside the mounting bracket through the oil pipe connector, thereby adjusting the angle of the oil pipe connector to adapt to the angle of the hose. This solves the problem of bending caused by the non-perpendicular connection between the hose and the four-way oil pipe head, which leads to premature damage of the hose.

[0004] However, the four-way oil pipe head in the above patent has the following problems: (1) it can only rotate in one direction, resulting in a small adjustment range of the oil pipe head; (2) after the angle of the oil pipe head is adjusted, it cannot remain stable and will fall due to gravity; (3) it is difficult to connect the oil pipe head to the external hose. If the two are connected by a flange and both the oil pipe head and the hose are fixed, the flange holes on the oil pipe head and the hose may not be aligned, thus making it impossible to install. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a four-way oil pipe connector to solve the problem mentioned in the background art that the oil pipe connector can only rotate in one direction.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A four-way oil pipe connector includes a main body with a cavity inside. Multiple channels communicating with the cavity are located within the main body. A first corrugated hose is fixedly connected to the opening of each channel. First connecting plates are fixedly connected to both sides of the first corrugated hose on the main body. A transition pipe is pivotally connected to the two first connecting plates. Two second connecting plates are connected to the upper end of the transition pipe. The line connecting the two first connecting plates is perpendicular to the line connecting the two second connecting plates. A second corrugated hose is fixedly connected to the upper end of the transition pipe. A connecting pipe is pivotally connected to the two second connecting plates, and the lower end of the connecting pipe is fixedly connected to the second corrugated hose.

[0008] Preferably, there are four channels, which are respectively located on the four sides of the main body.

[0009] Preferably, the first connecting plate has a first mounting hole, and the two ends of the adapter pipe are fixedly connected to a first screw. The two first screws are respectively rotatably connected to the two first mounting holes, and the outer end of the first screw is threaded with a first fastening nut.

[0010] Preferably, the second connecting plate has a second mounting hole, and the two ends of the connecting pipe are fixedly connected to a second screw. The two second screws are respectively rotatably connected to the two second mounting holes, and the outer end of the second screw is threadedly connected to a second fastening nut.

[0011] Preferably, the end of the connecting pipe away from the second corrugated hose is fixedly connected to an annular mounting platform. The outer periphery of the top surface of the mounting platform is provided with an annular notch. A mounting plate is rotatably connected to the notch through a rotary bearing. A flange hole is provided on the mounting plate.

[0012] Preferably, a sealing ring is provided on the mounting platform inside the notch.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) By rotating the adapter on the first connecting plate and the connecting pipe on the second connecting plate, the angle of the connecting pipe in two different directions can be adjusted to adapt to hoses in different directions, thus solving the problem of the hose being bent due to the non-perpendicular connection between the hose and the oil pipe head four-way connector, which leads to premature damage to the hose.

[0015] (2) The connecting pipe is connected to the external hose through a flange. The hose is also equipped with a flange. When connecting, rotate the mounting plate to align the flange hole on the mounting plate with the flange hole on the hose.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1-3 A four-way hydraulic hose connector includes a main body 1 with a cavity inside. The main body 1 has four channels 2 communicating with the cavity, located on the four sides of the main body 1. A first corrugated hose 3 is fixedly connected to the opening of each channel 2. First connecting plates 4 are fixedly connected to both sides of the first corrugated hose 3 on the main body 1. A connecting pipe 5 is pivotally connected to each of the two first connecting plates 4. Two second connecting plates 6 are connected to the upper ends of the connecting pipe 5. The line connecting the two first connecting plates 4 is perpendicular to the line connecting the two second connecting plates 6. A second corrugated hose 7 is fixedly connected to the upper end of the connecting pipe 5. A connecting pipe 8 is pivotally connected to each of the two second connecting plates 6. The lower end of the connecting pipe 8 is fixedly connected to the second corrugated hose 7. The first corrugated hose 3 and the second corrugated hose 7 are both made of fluororubber, which is elastic, flexible, and has the advantages of high temperature resistance (-20℃~200℃), resistance to fuel oil, and synthetic hydraulic oil.

[0023] The first connecting plate 4 has a first mounting hole. First screws 9 are fixedly connected to both ends of the adapter pipe 5. The two first screws 9 are rotatably connected to the two first mounting holes. A first fastening nut 10 is threaded onto the outer end of each first screw 9. Loosening the first fastening nut 10 allows the first screw 9 to rotate, thereby adjusting the angle of the adapter pipe 5. Once the adapter pipe 5 reaches the desired angle, the first fastening nut 10 is tightened, pressing it firmly against the first connecting plate 4. This stabilizes the first screw 9, thus stabilizing the adapter pipe 5.

[0024] The second connecting plate 6 has a second mounting hole. Two second screws 11 are fixedly connected to both ends of the connecting pipe 8. The two second screws 11 are rotatably connected to the two second mounting holes, and the outer ends of the second screws 11 are threaded with second fastening nuts 12. Loosening the second fastening nuts 12 allows the second screws 11 to rotate, thereby adjusting the angle of the connecting pipe 8. Once the connecting pipe 8 reaches the desired angle, the second fastening nuts 12 are tightened to press firmly against the second connecting plate 6, thus stabilizing the second screws 11 and consequently stabilizing the connecting pipe 8.

[0025] The usage method of this embodiment is as follows: First, rotate the adapter pipe 5 on the first connecting plate 4. When the adapter pipe 5 reaches the required angle, tighten the first fastening nut 10 to stabilize the adapter pipe 5. Then, rotate the connecting pipe 8 on the second connecting plate 6. When the connecting pipe 8 reaches the required angle, tighten the second fastening nut 12 to stabilize the connecting pipe 8. Adjust the angle of the connecting pipe 8 in two different directions to adapt to hoses in different directions. This solves the problem of the hose being bent due to the non-perpendicular connection between the hose and the four-way connector of the oil pipe head, which leads to premature damage to the hose.

[0026] Example 2

[0027] Based on Embodiment 1, an annular mounting platform 13 is fixedly connected to the end of the connecting pipe 8 away from the second corrugated hose. An annular notch is provided on the outer periphery of the top surface of the mounting platform 13. A mounting plate 15 is rotatably connected to the notch through a rotary bearing 14. A flange hole 16 is provided on the mounting plate 15. A sealing ring 17 is provided on the inner side of the notch on the mounting platform 13.

[0028] The connecting pipe 8 is connected to the external hose via a flange. The hose also has a flange. During connection, the mounting plate 15 is rotated to align the flange hole 16 on the mounting plate 15 with the flange hole on the hose. Then, the two flanges are secured with bolts, facilitating the connection between the connecting pipe and the hose. The sealing ring 17 improves the sealing performance of the connection between the connecting pipe and the hose.
