Description

Technical Field

[0001] This utility model relates to the technical field of high-pressure oil pipe joints, and in particular to the technical field of a high-pressure oil pipe joint that prevents detachment. Background Technology

[0002] High-pressure hydraulic pipe joints are usually located in harsh working environments with high internal hydraulic oil pressure. Over time, the temperature of the hydraulic oil will rise, and high-temperature hydraulic oil can easily cause leakage in high-pressure hydraulic pipe joints. This not only causes instability in the entire system and prevents the system pressure from reaching its maximum, but also causes environmental pollution and, in severe cases, can even endanger safety.

[0003] To address the problems mentioned above, for example, application number CN201720473264.8 discloses a high-pressure precision oil pipe connector, including a connector, a cover at the tail end of the connector, and a sealing body inside the connector. The connector has an internal thread at its front end and an external thread at its tail end, and is threadedly connected to the front end of the cover. The tail end of the cover has a through hole. The front end of the high-pressure oil pipe is inserted into the sealing body and extends to the internal thread at the front end of the connector. The tail end of the high-pressure oil pipe passes through the through hole and extends out of the cover. A sealing groove is formed on the inner wall of the connector, and the sealing body is fixed in the sealing groove. This utility model has a sealing body inside the connector, which provides better sealing performance and can more effectively prevent oil leakage.

[0004] For example, application number CN201920835570.0 discloses a multi-channel high-pressure oil pipe joint, including a joint body. A fixed connecting pipe is fixedly installed at the lower end of the joint body, and a rotatable pipe is movably installed on the fixed connecting pipe. The fixed connecting pipe has a sealing sleeve inside, and the lower end of the rotatable pipe has an internal thread. A sealing washer is fixedly installed near the internal thread inside the rotatable pipe. An oil cavity is opened inside the joint body, and a first oil distribution pipe is fixedly installed at the upper end of the joint body. A reinforcing rib is fixedly installed between the upper surface of the joint body and the first oil distribution pipe. The use of a rotatable pipe allows the joint to rotate during use, reducing the axial stress of the oil pipe on the joint and avoiding oil leakage due to stress. The added sealing sleeve can improve the sealing performance of the joint, thereby preventing oil seepage at the joint.

[0005] However, all of the above structures have the following drawbacks:

[0006] Although the above structure improves the sealing effect through the sealing sleeve, the high-pressure oil pipe will vibrate when used in machinery, causing abnormal vibration at the connection between the high-pressure oil pipe and the joint. Under high pressure, the joint may fall off after long-term use. Summary of the Invention

[0007] The purpose of this invention is to solve the problems in the prior art by proposing a high-pressure oil pipe connector that prevents detachment, thereby improving the connection between the connector body and the high-pressure oil pipe and preventing detachment after a long period of time.

[0008] To achieve the above objectives, this utility model proposes an anti-detachment high-pressure oil pipe connector, comprising a connector body, a high-pressure oil pipe, a fixing component, an upper fixing plate, a lower fixing plate, a first extension plate, a first screw hole, a first locking screw, a first locking nut, an anti-detachment component, a top plate, a bottom plate, an upper anti-detachment plate, a lower anti-detachment plate, and a second extension plate; the two ends of the connector body are threadedly connected to the high-pressure oil pipe, and the outer wall of the high-pressure oil pipe is fitted with the fixing component, which includes an upper fixing plate, a lower fixing plate, a first extension plate, a first screw hole, a first locking screw, and a first locking nut, and the upper fixing plate and the lower fixing plate are attached to the upper and lower outer walls of the high-pressure oil pipe. Both ends of the upper and lower fixing plates are integrally formed with a first extension plate. The first extension plate has a first screw hole, and a first locking screw is installed in the internal thread of the first screw hole. A first locking nut is screwed onto the outer wall of the end of the first locking screw. The connector body is provided with an anti-detachment component, which includes a top plate, a bottom plate, an upper anti-detachment plate, a lower anti-detachment plate, and a second extension plate. The top plate and the bottom plate are located at the upper and lower ends of the connector body, respectively. The lower end face of the top plate is provided with an upper anti-detachment plate, and the upper end face of the bottom plate is provided with a lower anti-detachment plate. Both ends of the upper and lower anti-detachment plates are integrally formed with a second extension plate.

[0009] Preferably, the upper fixing plate and the lower fixing plate are two semi-circular structures, and the inner walls of the upper fixing plate and the lower fixing plate are provided with anti-slip rubber pads with a wavy surface.

[0010] Preferably, the first extension plate has an integrally formed first mounting base, and the first mounting base has a second screw hole.

[0011] Preferably, the second extension plate is integrally formed with a second mounting base, and the second mounting base has a third screw hole, which corresponds to the second screw hole.

[0012] Preferably, a second locking screw is installed in the second screw hole and the third screw hole with a common thread, and a second locking nut is screwed onto the outer wall of the end of the second locking screw.

[0013] Preferably, the upper anti-detachment plate and the lower anti-detachment plate are two semi-circular structures, and the inner walls of the upper anti-detachment plate and the lower anti-detachment plate are both attached to the joint body.

[0014] The beneficial effects of this utility model are:

[0015] This invention, through the combined use of a fixing component and an anti-detachment component, improves the connection strength between the connector body and the high-pressure oil pipe. First, the first locking screw is screwed into the first screw hole and secured with the first locking nut, thus ensuring the upper and lower fixing plates are tightly attached to and fixed to the outer wall of the high-pressure oil pipe. Simultaneously, the anti-slip rubber pad further increases the friction between the upper and lower fixing plates and the high-pressure oil pipe, providing an anti-slip effect. Next, the upper anti-detachment plate on the top plate and the lower anti-detachment plate on the bottom plate are snapped onto the connector body. Then, the second locking screw is screwed into the second and third screw holes in sequence and secured with the second locking nut, thereby connecting and securing the upper fixing plate to the upper anti-detachment plate and the lower fixing plate to the lower anti-detachment plate. This achieves a tight connection between the connector body and the high-pressure oil pipe, forming a unified structure that prevents the connector body and the high-pressure oil pipe from detaching under vibration, thus improving vibration resistance.

Both ends of the upper anti-detachment plate 403 and the lower anti-detachment plate 404 are integrally formed with a second extension plate 405. By screwing the first locking screw 305 into the first screw hole 304 and fixing it with the first locking nut 306, the upper fixing plate 301 and the lower fixing plate 302 are tightly attached to and fixed to the outer wall of the high-pressure oil pipe 2, which facilitates its use with the anti-detachment component 4.

[0023] See Figure 2 The upper fixing plate 301 and the lower fixing plate 302 are two semi-circular structures, and the inner walls of the upper fixing plate 301 and the lower fixing plate 302 are provided with anti-slip rubber pads 5 with a wavy surface.

[0028] The working process of this utility model:

[0029] In operation, this utility model discloses an anti-detachment high-pressure oil pipe connector.
