Description

Technical Field

[0001] This utility model belongs to the technical field, and specifically relates to a mating structure of a high-pressure oil pipe connector nut and a compression washer. Background Technology

[0002] When using high-pressure oil pipes, it is often necessary to use the fitting structure of pipe fitting nuts and compression washers to connect the high-pressure oil pipes to external pipelines.

[0003] The existing pipe fitting nut and compression washer mating structure, while capable of fixing and sealing the high-pressure oil pipe to the external pipeline, and preventing the mating structure from rotating and loosening due to the anti-loosening structure, thus avoiding affecting the firmness and sealing of the connection between the high-pressure oil pipe and the external pipeline, often uses a snap-fit ​​structure to prevent the connection from being turned in the opposite direction. While this ensures the connection effect between the high-pressure oil pipe and the external pipeline, it also makes it difficult for users to easily disassemble the loosening structure. Therefore, it is not easy for users to separate the high-pressure oil pipe from the external pipeline afterward, and it cannot repeatedly meet people's usage needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a mating structure for a high-pressure oil pipe connector nut and a compression washer. This structure not only ensures a secure connection between the high-pressure oil pipe and the external pipeline and prevents the connection from loosening on its own, but also allows users to easily separate the high-pressure oil pipe from the external pipeline, thereby better meeting people's usage needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a mating structure of a high-pressure oil pipe connector nut and a clamping washer, including a nut body disposed on the side end of the high-pressure oil pipe, a threaded connecting pipe that is screwed to the nut body disposed on the side end of the external pipeline, a fixing ring plate that is adapted to the nut disposed on the side end of the external pipeline, a first washer body disposed on the side end of the nut body, a second washer body that is adapted to the first washer body disposed on the side end of the fixing ring plate, an L-shaped mounting bracket disposed on the high-pressure oil pipe, a mounting groove disposed on the mounting bracket, an adjusting screw rotatably disposed in the mounting groove, a mounting block that is slidably connected to the mounting groove screwed on the adjusting screw, and an abutment pressure plate disposed on the mounting block for limiting and fixing the fixing ring plate.

[0006] As a further improvement of this utility model, the side end of the threaded connecting pipe is also provided with a plug-in pipe for insertion into the high-pressure oil pipe, and a plug-in washer is also provided on the outer wall of the plug-in pipe. Through the cooperation of the plug-in pipe and the plug-in washer, the connection between the high-pressure oil pipe and the external pipeline is made tighter, effectively preventing oil leakage and improving the sealing performance.

[0007] As a further improvement of this utility model, a support plate is also provided between the two ends of the mounting groove. The mounting block is slidably connected to the support plate. The mounting block is also provided with a locking bolt connected to the support plate. The support plate is provided with a locking hole connected to the locking bolt.

[0008] As a further improvement of this utility model, the locking bolt is a hand-tightening bolt.

[0009] As a further improvement of this utility model, the mounting slot is also provided with a handle for turning the adjusting screw. By turning the handle, the user can quickly drive the adjusting screw to rotate manually, thereby quickly clamping or loosening the clamping plate without the need for additional tools, thus improving operating efficiency.

[0010] As a further improvement of this utility model, the fixing plate is a regular hexagon. This allows users to easily adjust the fixing plate by turning it using tools such as wrenches.

[0011] As a further improvement of this utility model, the contact plate is provided with a through hole that can be fitted onto an external pipeline, and a fixing plate that engages and fixes with the fixing ring plate is also provided on the side end of the contact plate. This allows the first contact plate to be fitted onto the outside of the external oil pipe, thereby increasing the contact area with the fixing ring plate and enhancing the limiting effect on the fixing ring plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, the fixed and sealed connection between the high-pressure oil pipe and the external pipeline can be achieved through the screw connection between the nut body and the threaded connecting pipe, as well as the pressing action between the first washer body and the second washer body.

[0014] Secondly, after the high-pressure oil pipe is connected to the external pipeline, the mounting bracket, adjusting screw, mounting block, first abutting pressure plate and second abutting pressure plate can be used to abut and fix the side ends of the nut body and the fixing ring plate, preventing the nut body and the fixing ring plate from automatically shifting and turning. This makes the high-pressure oil pipe and the external pipeline have a more stable fixed connection and sealing connection. Moreover, by simply turning the adjusting screw in the opposite direction, the second abutting pressure plate can be released from abutting and fixing the fixing ring plate and the connection between the high-pressure oil pipe and the external pipeline, allowing the user to easily separate the high-pressure oil pipe from the external pipeline.

[0015] Thirdly, by providing locking bolts and locking holes between the mounting block and the support plate, users can lock the position of the mounting block to prevent slippage or displacement during use, ensuring the stability of the clamping structure. The locking bolts are hand-tightened, further enhancing ease of operation. Attached Figure Description

Detailed Implementation

[0022] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0023] like Figure 1 , 2As shown in Figure 3, a mating structure for a high-pressure oil pipe connector nut and a compression washer includes a nut body 102 disposed on the side end of a high-pressure oil pipe 100, a threaded connecting pipe 103 disposed on the side end of an external pipeline 101 and screwed to the nut body 102, a fixing ring plate 104 adapted to the nut disposed on the side end of the external pipeline 101, a first washer body 105 disposed on the side end of the nut body 102, a second washer body 106 adapted to the first washer body 105 disposed on the side end of the fixing ring plate 104, an L-shaped mounting bracket 107 disposed on the high-pressure oil pipe 100, a mounting groove 108 disposed on the mounting bracket 107, an adjusting screw 109 rotatably disposed in the mounting groove 108, a mounting block 110 slidably connected to the adjusting screw 109 and the mounting groove 108, and an abutment pressure plate 111 disposed on the mounting block 110 for limiting and fixing the fixing ring plate 104.

[0024] like Figure 1 , 4 As shown, the mounting slot 108 is also equipped with a handle 112 for turning the adjusting screw 109. Using the handle 112, the user can quickly drive the adjusting screw 109 to rotate manually, enabling the clamping or loosening of the clamping plate quickly without the need for additional tools, thus improving operational efficiency.

[0025] like Figure 1 , 3 As shown, the fixing plate 104 is a regular hexagon. This allows users to easily adjust the fixing plate 104 by turning it using tools such as wrenches.

[0026] First, the nut body 102 at the side end of the high-pressure oil pipe 100 is screwed to the threaded connection pipe 103 at the side end of the external pipeline 101 to ensure that the two are tightly connected. During this process, the first washer body 105 and the second washer body 106 come into contact with each other and are pressed together to enhance the sealing performance. Thus, the initial fixed connection and sealing connection between the high-pressure oil pipe 100 and the external pipeline 101 are achieved.

[0027] After the high-pressure oil pipe 100 is connected to the external pipeline 101, the adjusting screw 109 can be turned by the handle 112 to adjust the position of the mounting block 110 in the mounting groove 108, thereby adjusting the position of the abutment plate 111 until the abutment plate 111 can abut against the side end of the fixing ring plate 104. This ensures the stability of the connection between the high-pressure oil pipe 100 and the external pipeline 101, prevents the nut body 102 and the fixing ring plate 104 from automatically shifting or turning, and ensures the stability of the connection.

[0028] If it is necessary to separate the high-pressure oil pipe 100 from the external pipeline 101, simply turn the adjusting screw 109 in the opposite direction to release the pressure plate 111 from the fixing ring plate 104, and it can be easily disassembled.

[0029] According to another embodiment of the present invention, such as Figure 4 As shown, a support plate 301 is also provided between the two ends of the mounting groove 108. The mounting block 110 is slidably connected to the support plate 301. The mounting block 110 is also provided with a locking bolt 302 connected to the support plate 301. The support plate 301 has a locking hole connected to the locking bolt 302. The locking bolt 302 is a hand-tightening bolt.

[0030] During the sliding operation of the mounting block 110 in the mounting groove 108, the sliding cooperation between the mounting block 110 and the support plate 301 allows the mounting block 110 and the contact plate 111 to slide more stably. After the contact plate 111 presses against the fixed ring plate 104, the locking bolt 302 passes through the side wall of the mounting block 110 and connects to the locking hole, thus fixing the connection between the mounting block 110 and the support plate 301 and better preventing the mounting block 110 from sliding independently, thereby ensuring the limiting effect of the contact plate 111 on the fixed ring plate 104. When it is necessary to disassemble the connection between the high-pressure oil pipe 100 and the external pipeline 101, simply separate the locking bolt 302 from the locking hole and release the fixation of the connection between the mounting block 110 and the support plate 301.

[0031] According to another embodiment of the present invention, such as Figure 3 As shown, the threaded connecting pipe 103 is also provided with a plug pipe 201 for insertion into the high-pressure oil pipe 100 at its side end, and a plug gasket 202 is also provided on the outer wall of the plug pipe 201. Through the cooperation of the plug pipe 201 and the plug gasket 202, the connection between the high-pressure oil pipe 100 and the external pipeline 101 is made tighter, effectively preventing oil leakage and improving sealing performance.

[0032] Furthermore, during the process of connecting the high-pressure oil pipe 100 to the external pipeline 101, the insertion pipe 201 will be inserted into the high-pressure oil pipe 100. The insertion gasket 202 on the outer wall of the insertion pipe 201 will fit tightly against the inner wall of the high-pressure oil pipe 100, further improving the sealing performance and better preventing oil leakage.

[0033] According to another embodiment of the present invention, such as Figure 4 As shown, the contact plate 111 is provided with a through hole 304 that can be fitted onto the external pipeline 101, and a fixing plate 303 that is engaged and fixed to the fixing ring plate 104 is also provided on the side end of the contact plate 111. This allows the first contact plate 111 to be fitted onto the outside of the external oil pipe, thereby increasing the contact area with the fixing ring plate 104 and enhancing the limiting effect on the fixing ring plate 104.

[0034] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
