Description

Technical Field

[0001] The invention relates to the technical field of adapter structures, and in particular to a direction-adjustable, anti-loosening and anti-collision right-angle adapter. Background Art

[0002] Common adapters are made by bending rigid thin-walled pipes, and have low impact resistance. When subjected to external force, the adapters can easily rupture, causing leakage of the liquid in the pipe. When the adapter is impacted, the connected oil port, as the main stress point, is more likely to be damaged, causing leakage. Secondly, common adapters have poor anti-loosening ability. After multiple rotations or swings, the connection of the pipeline can easily loosen, causing leakage of the liquid in the pipe. During installation, common adapters cannot be connected in a fixed direction, requiring multiple debugging, which reduces installation efficiency. Summary of the invention

[0003] In view of this, the present invention provides a direction-adjustable anti-loosening and anti-collision right-angle adapter, which can reduce the external force impact on the oil port connected to it and achieve an anti-collision effect.

[0004] A direction-adjustable anti-loosening and anti-collision right-angle adapter, comprising an anti-collision adapter seat, a threaded sleeve, a locking nut, a ferrule and an O-ring;

[0005] The anti-collision adapter is provided with two interfaces with different diameters, and the central axes of the two interfaces are perpendicular to each other. The interface with a larger diameter is composed of two cylindrical sections, and both cylindrical sections are processed with external threads. The interface with a smaller diameter is a cylindrical section of equal diameter, and the external threads are also processed on the outer circle. The ferrules are respectively clamped on the two interfaces of the anti-collision adapter, and the O-rings are respectively in contact with the outer grooves of the ferrules. The locking nut fixes the ferrules on the interfaces, and the threaded sleeve is threadedly matched with the large cylindrical section on the interface with a larger diameter. The inner hole of the threaded sleeve is larger than the outer diameter of the locking nut. When the adapter is connected to an external device, the threaded sleeve is tightened in reverse until the bottom of the threaded sleeve contacts the end face of the connecting component.

[0006] Furthermore, the external threads on the two interfaces of the anti-collision adapter have opposite rotation directions.

[0007] Furthermore, the number of interfaces on the anti-collision adapter is more than three.

[0008] Furthermore, after the anti-collision adapter has determined the orientation of the interface with a larger diameter, the orientation of the interface with a smaller diameter can be fixed by tightening the locking nut of the interface with a smaller diameter, thereby achieving the purpose of adjustable direction.

[0009] Furthermore, the interface with a small diameter cooperates with a locking nut, a ferrule and an O-ring to form a joint for connecting the pipeline, and the interface with a large diameter cooperates with a locking nut, a ferrule and an O-ring to form a joint for connecting the oil seat.

[0010] Beneficial effects:

[0011] 1. The present invention provides a threaded sleeve on an interface of the anti-collision adapter. When the adapter is connected to an external device, the threaded sleeve is tightened in reverse until the bottom of the threaded sleeve contacts the end face of the connecting component. When the anti-collision adapter or the external connecting oil port is impacted, the force of the anti-collision adapter is directly transmitted to the connecting component through the threaded sleeve, thereby reducing the external force impact on the oil port connected thereto and achieving an anti-collision effect.

[0012] 2. The rotation directions of the threads on the two joints of the anti-collision adapter of the present invention are opposite. When the anti-collision adapter connected to the external oil pipe becomes loose due to external force, if the loosening direction is the same as the rotation direction of one thread in the anti-collision adapter, the other thread will rotate in the opposite direction and tighten the adapter, thereby achieving the effect of preventing loosening.

[0013] 3. When the oil seat and the pipeline are connected, the orientation of one of the joints is determined by tightening the locking nut on the other joint, thereby achieving the purpose of adjustable direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0021] As attached Figure 1 As shown, the present invention provides a direction-adjustable anti-loosening and anti-collision right-angle adapter, comprising an anti-collision adapter seat 1, a threaded sleeve 2, a locking nut 3, a ferrule 4 and an O-ring 5.

[0022] The anti-collision adapter 1 is provided with two interfaces of different diameters, and the central axes of the two interfaces are perpendicular to each other. The interface with a larger diameter is located directly below the anti-collision adapter 1, and the interface is composed of two cylindrical sections. The diameter of the front cylindrical section is smaller than the diameter of the rear cylindrical section, and both cylindrical sections are processed with external threads; the interface with a smaller diameter is located on the left side of the anti-collision adapter 1, and the interface is a cylindrical section of equal diameter, and external threads are also processed on the outer circle; the rotation directions of the two threads should be opposite, and when the anti-collision adapter 1 connected to the external oil pipe is loosened due to external force, if the loosening direction is the same as the rotation direction of one thread in the anti-collision adapter 1, the other thread will rotate in the opposite direction and then tighten the adapter to achieve the anti-loosening effect.

[0023] The ferrules 4 are respectively clamped at the front ends of the two interfaces of the anti-collision adapter 1, and the O-rings 5 ​​are respectively in contact with the outer grooves of the ferrules 4. The locking nut 3 fixes the ferrules 4 on the interface. The threaded sleeve 2 is threadedly matched with the large cylindrical section on the interface with a large diameter. The inner hole of the threaded sleeve 2 is larger than the outer diameter of the locking nut 3. The interface with a small diameter cooperates with the locking nut, the ferrule and the O-ring to form a joint 2 connected to the pipeline 6. The interface with a large diameter cooperates with the locking nut, the ferrule and the O-ring to form a joint 1 connected to the oil seat. Figure 1 Shown in the dashed box.

[0024] As attached Figure 2 and 3 As shown, the connector 2 is used to connect the pipeline 6 , and the connector 1 is used to connect the oil seat 7 .

[0025] The steps for using the anti-collision right-angle adapter of the present invention are as follows:

[0026] Step 1: Connect the connector 1 to the oil seat 7;

[0027] Step 2: Determine the orientation of connector 2 and tighten the locking nut 3 at connector 1;

[0028] Step 3: Tighten the threaded sleeve 2 in the reverse direction until the bottom of the threaded sleeve 2 contacts the end surface of the oil seat 7;

[0029] Step 4: Align the pipe port 6 with the connector 1 and tighten the locking nut 3 at the connector 2.

[0030] If it is extended to be used as a multi-way adapter, the order of steps one to three remains unchanged. When the anti-collision adapter seat or the external connecting oil port is impacted, the force of the anti-collision adapter is directly transmitted to the oil seat through the threaded sleeve, reducing the external force impact on the oil port connected to it, thereby achieving an anti-collision effect.

[0031] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
