[0033] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0034] As Figures 1-5As shown, it shows a power oil pipe quick connector in an embodiment of the present disclosure, including a connecting pipe body 1, the connecting pipe body 1 has a connecting cavity 101, the elastic sheet 2 is swingly arranged in the connecting cavity 101 of the connecting pipe body 1, the elastic sheet 2 is turned at an angle with the axial direction of the connecting pipe body 1, the elastic sheet 2 is used to block the power oil pipe from separating from the connecting cavity 101, the sliding piece 3 is slidably arranged in the connecting cavity 101 of the connecting pipe body 1, the sliding piece 3 slides along the axial direction of the connecting pipe body 1, and the sliding of the sliding piece 3 is used to drive the elastic sheet 2 to turn parallel to the axial direction of the connecting pipe body 1.

[0035] In the embodiment, when the power oil pipe is inserted into the connecting cavity 101, the elastic sheet 2 is in a turned state and blocks the power oil pipe from separating. When disassembly is needed, the sliding piece 3 is pushed to slide axially, the elastic sheet 2 is driven to turn parallel to the axial direction of the connecting pipe body 1, and the power oil pipe can be smoothly pulled out. The quick connection and disassembly of the power oil pipe are realized, the operation is simple, and the work efficiency is improved. The material of the connecting pipe body 1 can be selected as high-strength plastic to reduce the weight; the surface of the elastic sheet 2 can be treated to prevent slipping to increase the resistance. In the prior art, the connecting end of the general power oil pipe is a groove, and then the connection is achieved through a nut or other fastener. The scheme of the present disclosure only needs to make the elastic sheet 2 be clamped at the groove of the power oil pipe, so that the fixation is more stable and the fixation effect is better.

[0036] In some examples, a connecting frame 4 is further included, the connecting frame 4 is arranged in the connecting cavity 101, and the elastic sheet 2 has a plurality of elastic sheets 2, which are distributed along the circumferential direction of the connecting shaft.

[0037] For example, the plurality of elastic sheets 2 distributed along the circumference work cooperatively, more uniformly block the power oil pipe, and enhance the reliability of the connection. The fixation effect of the joint on the power oil pipe is improved, and the firmness of the connection is ensured. The number of the elastic sheets 2 can be increased to improve the stability of the connection; the connecting frame 4 is made of a light and strong alloy material.

[0038] In some examples, the elastic sheet 2 is integrally bent and formed.

[0039] For example, the integrally bent and formed elastic sheet 2 has a simple structure, reliable strength, and can stably play a blocking role, reduces the manufacturing difficulty and cost of the elastic sheet 2, ensures the performance, optimizes the bending process, and improves the strength and durability of the elastic sheet 2.

[0040] In some examples, the sliding piece 3 has a plurality of openings 301, the plurality of openings 301 are distributed along the circumferential direction of the sliding piece 3, and each of the openings 301 is provided with one elastic sheet 2.

[0041] For example, when the sliding piece 3 slides, the end of the opening 301 pushes the elastic sheet 2 to flip, realizing the control of the connection state of the power-assisted oil pipe, ensuring the effective driving of the sliding piece 3 to the elastic sheet 2, and making the operation more accurate and reliable. The shape and size of the opening 301 are adjusted to more accurately drive the elastic sheet 2 to flip, and the opening 301 can be a strip-shaped groove.

[0042] In some examples, an elastic member 5 is further included, one end of the elastic member 5 is connected with the connecting pipe body 1, the other end of the elastic member 5 is connected with the sliding piece 3, and the elastic member 5 is used to provide a force for the sliding piece 3 to move away from the elastic sheet 2.

[0043] For example, in a normal state, the elastic member 5 is preferably a spring, which pushes the sliding piece 3 away from the elastic sheet 2. When disassembling, the operator only needs to overcome the spring force to press the sliding piece 3, and after the operation is completed, the spring resets the sliding piece 3. The automatic reset function is provided, so that the joint remains in the connected state when it is not operated. A spring with a higher elastic coefficient can be selected; the surface of the spring is subjected to corrosion prevention treatment.

[0044] In some examples, the connecting pipe body 1 has a first inlet 102 and a second inlet 103, the connecting cavity 101 is used to connect the first inlet 102 and the second inlet 103, the connecting frame 4 is located at one end close to the second inlet 103, and the connecting pipe body 1 has an annular groove 104 at one end close to the first inlet 102; the sliding piece 3 further has a hook portion 302, the hook portion 302 is used to enter the annular groove 104, and the annular groove 104 blocks the sliding piece 3 from separating from the connecting pipe body 1.

[0045] For example, when the sliding piece 3 slides, the hook portion 302 enters the annular groove 104, preventing the sliding piece 3 from separating from the connecting pipe body 1, and ensuring the integrity of the structure. It is ensured that the sliding piece 3 stably slides in the connecting pipe body 1 without falling off, thereby improving the reliability of the joint. A buffer pad is arranged in the annular groove 104 to reduce the impact of the hook portion 302; the shape of the hook portion 302 is optimized to improve the connection stability.

[0046] In some examples, the hook portion 302 has a plurality of hook portions 302, and the plurality of hook portions 302 are distributed along the circumferential direction of the sliding piece 3.

[0047] For example, the plurality of hook portions 302 work together to more effectively prevent the sliding piece 3 from accidentally separating. The connection stability of the sliding piece 3 and the connecting pipe body 1 is further enhanced. The number of hook portions 302 can be increased to improve the anti-separation effect; the hook portions 302 are subjected to strengthening treatment.

[0048] In some examples, the hook portion 302 is integrally formed with the sliding piece 3, and the hook portion 302 can be flipped along the connection point of the sliding piece 3.

[0049] For example, during the sliding of the sliding member 3, the hook portion 302 can adapt to the internal structure of the connecting pipe body 1 and smoothly enter the annular groove 104. The smooth sliding and stable connection of the sliding member 3 are ensured. A plastic material with higher strength is selected; and the connecting position of the hook portion 302 and the sliding member 3 is thickened.

[0050] In some examples, the connecting frame 4 has a third inlet 401 in communication with the second inlet 103, and the connecting frame 4 is rotatably arranged in the connecting pipe body 1.

[0051] For example, a plastic material with higher strength is selected; and the connecting position of the hook portion 302 and the sliding member 3 is thickened. A lubricant is added to the contact position of the connecting frame 4 and the connecting pipe body 1 to reduce friction; and the rotating structure of the connecting frame 4 is optimized to improve the rotating flexibility. Moreover, the connecting frame 4 can rotate, and the connector can be conveniently connected.

[0052] In some examples, the sliding member 3 has a pressing portion 303 at the end away from the connecting frame 4, the pressing portion 303 is distributed along the circumferential direction of the sliding member 3, and the pressing portion 303 is used to increase the contact area.

[0053] For example, during disassembly, the pressing portion 303 is pressed to push the sliding member 3 to slide, and the increased contact area makes the operation more labor-saving. The operator is facilitated to perform the disassembly operation, and the convenience of use is improved. The pressing portion 303 is made of a more wear-resistant rubber material; and the shape of the pressing portion 303 is adjusted to improve the pressing comfort.
