Description

Technical Field

[0001] The utility model relates to the technical field of high-stability automobile oil pipe joints, and particularly relates to a high-stability automobile oil pipe joint. Background Technique

[0002] As the living standard improves, automobiles have become one of the means of transportation in families. During the use of fuel vehicles, gasoline needs to be transported into the engine to provide power, so oil pipes and oil pipe joints are required.

[0003] During the use of existing oil pipe joints, most of them are fixed by hose clamps after the oil pipe is connected to the joint. Since the oil pipe is soft, the vibration generated during the driving of the automobile will drive the oil pipe to vibrate, resulting in easy shaking and loosening between the oil pipe and the joint. Moreover, most of the oil pipe joints are integrally injection-molded, resulting in poor seismic resistance.

[0004] Therefore, this application provides a high-stability automobile oil pipe joint to meet the needs. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems existing in the above background technique, and to propose a high-stability automobile oil pipe joint.

[0006] The technical problem to be solved by the utility model is to provide a high-stability automobile oil pipe joint to solve the problem of poor seismic resistance of the existing high-stability automobile oil pipe joint.

[0007] To solve the above technical problem, the utility model provides the following technical solution:

[0008] A high-stability automobile oil pipe joint, comprising: an oil pipe joint main body, a first joint is embedded on the left side of the oil pipe joint main body, an inner joint is embedded on the right side of the oil pipe joint main body, a second joint is embedded in the middle of the right side of the inner joint, and shock-absorbing bent plates arranged at equal distances in a ring shape are fixedly connected to the periphery of the inner wall between the inner joint and the oil pipe joint main body.

[0009] Preferably, a hose is arranged between the left side of the first joint and the inner joint, the first joint is communicated with the inner joint through the hose, and a first spring is fixedly connected between the shock-absorbing bent plate and the inner joint.

[0010] Preferably, sliding grooves are opened at both the upper and lower ends on the right side of the inner joint, sliders are slidably connected inside the sliding grooves, a support frame is fixedly connected to the right side of the sliders, a support ring is fixedly connected to the right side between the two support frames, and a clamping hole is opened in the middle of the support ring.

[0011] Preferably, second springs are fixedly connected to both the upper and lower sides of the inner wall of the sliding groove and the slider.

[0012] Preferably, a clamping hole is formed in the middle of the inner wall of the support ring, and movable clamping plates are arranged on both the upper and lower sides of the inner wall of the clamping hole. The inner diameter of the inner wall of the clamping hole is larger than the diameter of the second joint.

[0013] Preferably, the side of the movable clamping plate away from the inner wall of the clamping hole is an inward concave arc surface, and a third spring is fixedly connected between the movable clamping plate and the inner wall of the clamping hole.

[0014] Compared with the prior art, the utility model has at least the following beneficial effects:

[0015] In the above solution, by providing an inner joint, when the oil pipe joint body is subjected to an external vibration force, the inner joint can buffer the external vibration force through the damping bending plate between the inner joint and the oil pipe joint body, so that the oil pipe is not easily loosened after being connected to the second joint. At the same time, when the damping bending plate deforms to buffer the external vibration force, the deformed damping bending plate will squeeze the second spring to further increase the earthquake resistance, and the elastic force of the second spring can provide resilience for the deformed damping bending plate, so that the damping bending plate and the second spring are not likely to continuously generate aftershocks after being stressed, thereby improving the earthquake resistance.

[0016] In the above solution, by providing a support ring, when an external oil pipe passes through the clamping hole and is connected to the second joint, the movable clamping plate in the clamping hole will always closely fit the outer side of the external oil pipe through the elastic force of the third spring, forming a buffer zone on the right side of the connection area between the oil pipe and the second joint. When the oil pipe shakes, the elastic force of the movable clamping plate and the third spring in the clamping hole will buffer the shaking, so that the force generated by the shaking of the oil pipe will not be directly transmitted to the second joint area, improving the stability of the connection between the oil pipe and the second joint.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

[0027] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, an embodiment of the present invention provides a highly stable automotive oil pipe joint, including: the main body of the oil pipe joint 1, the first joint 101 is embedded on the left side of the main body of the oil pipe joint 1, the inner joint 2 is embedded on the right side of the main body of the oil pipe joint 1, the second joint 204 is embedded in the middle of the right side of the inner joint 2, and shock-absorbing bent plates 205 arranged at equal intervals in a ring shape are fixedly connected around the inner wall of the inner joint 2 and the main body of the oil pipe joint 1;

[0028] When the main body of the oil pipe joint 1 is subjected to an external vibration force, the inner joint 2 can buffer the external vibration force through the shock-absorbing bent plates 205 between it and the main body of the oil pipe joint 1, so that the inner joint 2 is not easily loosened after the oil pipes are connected.

[0029] In this embodiment, as Figures 2 - 4 shown;

[0030] A hose is provided between the first joint 101 and the left side of the inner joint 2. The first joint 101 is connected to the inner joint 2 through the hose in a penetrating manner. A first spring 206 is fixedly connected between the shock-absorbing bent plate 205 and the inner joint 2;

[0031] When the inner joint 2 is shaking, the inner joint 2 can still be connected to the first joint 101 through the hose in a penetrating manner. And the deformed shock-absorbing bent plate 205 can squeeze the first spring 206. The elastic force of the first spring 206 can play a role in restoring elasticity to the deformed shock-absorbing bent plate 205, making it not easy for the shock-absorbing bent plate 205 to generate aftershocks and improving the seismic resistance;

[0032] Sliding grooves 201 are provided at both the upper and lower ends on the right side of the inner joint 2. Sliders 202 are slidably connected inside the sliding grooves 201. A support frame 203 is fixedly connected to the right side of the slider 202. A support ring 3 is fixedly connected to the right side between the two support frames 203. A card hole 301 is provided in the middle of the support ring 3. Second springs 207 are fixedly connected to both the upper and lower sides of the inner wall of the sliding groove 201 and the slider 202. A card hole 301 is provided in the middle of the inner wall of the support ring 3. Movable clamping plates 302 are provided on both the upper and lower sides of the inner wall of the card hole 301. The inner diameter of the inner wall of the card hole 301 is larger than the diameter of the second joint 204;

[0033] When the external oil pipe is connected to the second joint 204, the external oil pipe first needs to penetrate through the card hole 301 in the middle of the support ring 3, so that the connection area between the external oil pipe and the second joint 204 is not easy to bend and cause looseness. During the shaking of the external oil pipe, the support ring 3 can move up and down along the sliding groove 201 through the support frame 203 and the slider 202 for buffering. When the slider 202 moves, it will squeeze one side of the second spring 207 and be pulled by the second spring 207 on the other side, so that the slider 202 will return to its original position after moving;

[0034] The side of the movable clamping plate 302 away from the inner wall of the card hole 301 is an inward concave arc surface. A third spring 303 is fixedly connected between the movable clamping plate 302 and the inner wall of the card hole 301;

[0035] When the external oil pipe enters the card hole 301, the movable clamping plate 302 will always closely fit the outer side of the oil pipe through the elastic force of the third spring 303, making it not easy for the oil pipe and the card hole 301 to have a gap and cause looseness. And the movable clamping plate 302 with an inward concave arc surface can more easily fit the outer side of the oil pipe, improving the fixing of the oil pipe.
