[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown;

[0025] A sealing structure for an engine oil outer pipe head comprises a pipe body 1.

[0026] In this embodiment: After checking, the public (announcement) number: CN216103669U discloses an oil pipe structure. Although the design can elastically connect the sealing cover and the screw cap through the connecting piece, the loss of the sealing cover can be effectively avoided during use. However, the sealing cover of the oil pipe structure is sleeved on its end, and is not firmly connected to the oil pipe body. It will fall off if scratched during transportation, thereby causing oil leakage. Moreover, the long-term plugging and unplugging of the sealing cover will cause it to be loosely connected to the oil pipe, thereby causing the sealing effect to deteriorate. In order to solve this technical problem, a sealing component 2 is added on this basis.

[0027] More specifically:

[0028] like Figures 1 to 5 As shown:

[0029] In combination with the above content: the sealing assembly 2 includes a connecting ring 21, a groove 22 and an inner tube head 23, the connecting ring 21 is fixedly connected to the outer side of the end of the tube body 1, the inner tube head 23 is fixedly connected at the central position of the connecting ring 21, a first oil outlet 24 is opened at the end of the inner tube head 23, an outer tube head 212 is rotatably connected to the outer side of the end of the inner tube head 23, a second oil outlet 211 is opened on the outer side of one end of the outer tube head 212, a rotating block 25 is fixedly connected to the outer surface of one end of the outer tube head 212, the rotating block 25 is slidably connected to the connecting ring 21, a groove 22 is opened on the upper surface of the connecting ring 21, a block 26 is slidably connected to the inside of the through groove opened on the outer side of one end of the rotating block 25, a spring 27 is sleeved on the outer surface of the block 26, and a limiting ball 28 is fixedly connected to the end of the block 26.

[0030] When the user needs to use it, the user rotates the rotating block 25, thereby driving the outer tube head 212 at the end of the rotating block 25 to rotate. When the second oil outlet 211 and the first oil outlet 24 at the ends of the outer tube head 212 and the inner tube head 23 coincide with each other, the user can squeeze out the engine oil through the fan-shaped through holes of the second oil outlet 211 and the first oil outlet 24. The rotating connection mode of the rotating block 25 and the outer tube head 212 has the effects of good sealing and convenient operation, and solves the problems of loose connection and poor sealing effect caused by long-term plugging and unplugging of traditional sealing covers. The damping sense of rotation and the anti-mistouch function can be realized by the clamping block 26 inside the rotating block 25. When the user rotates the rotating block 25, the clamping block 26 will move vertically upward and will be inserted into the clamping slot 22 under the action of the spring 27. The angle of each clamping slot 22 can realize the opening and closing of the engine oil pipe, thereby increasing the sealing of the engine oil pipe and preventing engine oil leakage caused by mistouch.

[0031] It should be noted that the first oil outlet 24 and the second oil outlet 211 are both fan-shaped through holes and are alternately arranged. The oil pipe can be opened and closed by rotation. A through groove is opened inside the rotating block 25, and the clamping block 26 is arranged inside the through groove. The two ends of the spring 27 are respectively fixedly connected to the outer side of one end of the clamping block 26 and the inner side of the through groove of the rotating block 25.

[0032] Going further:

[0033] In an optional embodiment, a first side through groove 29 is formed on the outer side of the end of the inner pipe head 23 , and a second side through groove 210 is formed on the outer side of the end of the outer pipe head 212 .

[0034] In the present embodiment: the first side through groove 29 and the second side through groove 210 can make the oil pipe be applied with oil more evenly when in use, and the first side through groove 29 and the second side through groove 210 can achieve oil application on the side of a narrow gap, thereby improving the practicality of the oil pipe.

[0035] It should be noted that the second side through groove 210 and the first side through groove 29 are both rectangular through grooves and are alternately arranged. The first side through groove 29 and the second side through groove 210 can be opened and closed by rotation.

[0036] Going further:

[0037] In an optional embodiment, the outer surface of the outer pipe head 212 is threadedly connected to a limiting ring 213 , and an annular groove 215 is formed on the outer side of one end of the limiting ring 213 .

[0038] In this embodiment: by rotating the limit ring 213, the limit ball 28 at the end of the block 26 can enter the annular groove 215, thereby preventing the block 26 from moving in the vertical direction, increasing the locking function of the oil pipe, and further increasing the sealing and reliability of the oil pipe.

[0039] It should be noted that: a thread is provided on the outer side of the end of the outer tube head 212, and the limiting ring 213 is connected to the outer tube head 212 via the thread.

[0040] Going further:

[0041] In an optional embodiment, a ball 214 is installed on one side of the block 26 .

[0042] In this embodiment, the ball 214 can reduce the friction between the block 26 and the slot 22, so that the user can rotate the rotating block 25 more smoothly, improve the user experience, and increase the service life of the oil pipe.

[0043] Going further:

[0044] In an optional embodiment, an anti-slip strip 216 is fixedly connected to the outer surface of the rotating block 25 in an annular shape, and the material of the anti-slip strip 216 is rubber.

[0045] In this embodiment: the anti-slip strip 216 on the outer surface of the rotating block 25 can prevent the user from being unable to rotate the rotating block 25 due to hand slippage, and the anti-slip strip 216 is made of rubber, which has a large friction between the user's hand, thereby improving the user experience and increasing the practicality of the engine oil pipe.

[0046] Working principle: When it is needed, the user rotates the rotating block 25, thereby driving the outer tube head 212 at the end of the rotating block 25 to rotate. When the second oil outlet 211 at the end of the outer tube head 212 coincides with the first oil outlet 24 at the end of the inner tube head 23, the user can squeeze out the engine oil through the second oil outlet 211 and the fan-shaped through holes of the first oil outlet 24. The rotating connection mode of the rotating block 25 and the outer tube head 212 has the effects of good sealing and convenient operation, and solves the problems of loose connection and poor sealing effect caused by long-term plugging and unplugging of traditional sealing covers. The damping sense of rotation and the anti-mistouch function can be realized through the clamping block 26 inside the rotating block 25. When the user rotates the rotating block 25, the clamping block 26 will move vertically upward and will be inserted into the clamping groove 22 under the action of the spring 27. The angle of each clamping groove 22 can realize the opening and closing of the engine oil pipe, which increases the sealing of the engine oil pipe and prevents engine oil leakage caused by mistouch. 9 and the second side through groove 210 can make the oil pipe more evenly spread the oil when in use. The first side through groove 29 and the second side through groove 210 can realize the oil coating on the side of the narrow gap, thereby improving the practicality of the oil pipe. By rotating the limit ring 213, the limit ball 28 at the end of the block 26 can enter the annular groove 215, thereby preventing the block 26 from moving in the vertical direction, increasing the locking function of the oil pipe, and further increasing the sealing and reliability of the oil pipe. The ball 214 can reduce the friction between the block 26 and the groove 22, making the user smoother when rotating the rotating block 25, improving the user's experience, and at the same time increasing the service life of the oil pipe. The anti-skid strip 216 on the outer surface of the rotating block 25 can prevent the user from being unable to rotate the rotating block 25 due to hand slippage, and the anti-skid strip 216 is made of rubber, which has a large friction with the user's hand, thereby improving the user's experience and increasing the practicality of the oil pipe.
