DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Reference Figure 1-9 As shown: a portable plastic oil collecting tank, comprising an oil collecting tank body 3, the bottom of the oil collecting tank body 3 is fixedly connected with an oil pool pipe 1, the bottom end of the oil collecting tank body 3 is fixedly connected with a plurality of plug-in blocks 7, the top of the oil collecting tank body 3 is fixedly connected with a mounting ring 2, the top outer surface of the mounting ring 2 is installed with a plurality of connecting mechanisms 6, the bottom of the oil collecting tank body 3 is installed with an overflow mechanism 4, and the bottom outer edge of the oil collecting tank body 3 is installed with an oil return mechanism 5; The connecting mechanism 6 includes an outer tube 61 and an extrusion rod 63. The outer surface of the outer tube 61 is fixedly connected with a mounting hole 62. The extrusion rod 63 is slidably connected to the outer tube 61, and the bottom end of the extrusion rod 63 is fixedly connected to an extrusion plate 632. A top tube 61 is provided at the top of the outer tube 61. The extrusion rod 63 is slidably installed on the inner side of the top tube 611. The extrusion plate 632 is slidably installed inside the outer tube 61. A driving member 64 is installed on one side of the bottom end of the extrusion plate 632. A rotating tube 65 is installed on the inner side of the top tube 611. A driving groove 651 is provided on one side of the outer surface of the rotating tube 65. A mounting groove 652 is provided on the inner side of the rotating tube 65. A third spring 68 is installed inside the mounting groove 652. The top end of the third spring 68 is fixedly connected to the bottom end of the extrusion plate 632. The inner side of the bottom end of the outer tube 61 is fixedly connected to the bottom plate 612. The bottom end of the rotating tube 65 passes through the bottom plate 612, and the rotating tube 65 is rotatably connected to the bottom plate 612.

[0023] In this embodiment, when installing the oil collecting tank body 3, the plug-in block 7 at the bottom of the oil collecting tank body 3 is used for plugging, and then the connection mechanism 6 on the top outside of the mounting ring 2 is used for connection. When plugging, the center rod 66 and the limit plate 67 are installed and connected with the automobile oil tank, thereby completing the preliminary plug-in connection. After the installation is completed, when the extrusion rod 63 is pressed, the extrusion plate 632 can be driven to move together, so that the driving member 64 starts to move downward.

[0024] When the driving member 64 moves downward, the extrusion plate 632 will slide inside the rotating tube 65, and during the sliding process, it will slide along the inclined trapezoidal block 653. At this time, the extrusion plate 632 will slide inside the driving groove 651, thereby squeezing the second spring 643 to compress it. After that, after the extrusion plate 632 passes over the trapezoidal block 653, the elastic action of the second spring 643 will push the extrusion plate 632 to continue to return to its original position.

[0025] Because the squeezing rod 63 will also squeeze the third spring 68 during the process of descending, when the squeezing plate 632 cannot continue to descend due to the restriction of the rotating tube 65, the squeezing rod 63 can only be released. Under the elastic action of the third spring 68, the squeezing rod 63 is reset, and the squeezing plate 632 can only move along the route of the X-shaped structure inside the rotating tube 65, so that in this process, a force is applied to the rotating tube 65 to make it rotate.

[0026] As the rotating tube 65 rotates, the center rod 66 will also rotate. After the stop plate 67 rotates ninety degrees following the center rod 66, it will complete the transposition, so that after the oil collecting tank body 3 is plugged and installed, it can be rotated ninety degrees in the original plug-in channel.

[0027] This structure can be quickly installed and removed, suitable for occasions that require frequent movement or temporary emergency response, such as vehicle maintenance or field work. It avoids the cost and complexity of installing a permanent fixed system. In cases such as dealing with automotive oil leaks, portable equipment can be quickly deployed to the leak point, reducing environmental pollution and safety risks, and facilitating regular inspection and maintenance.

[0028] Embodiment 2: Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the driving member 64 includes a fixed block 641, the top of the fixed block 641 is fixedly connected to the bottom of the extrusion plate 632, a sliding groove 644 is provided at the bottom of the fixed block 641, and a top block 642 is slidably connected to the inner side of the sliding groove 644. A second spring 643 is installed inside the top block 642, one end of the second spring 643 is fixedly connected to the inner wall of the sliding groove 644, the top block 642 is slidably installed inside the rotating tube 65, a sliding groove 613 is provided on the inner wall of the top of the outer tube 61, a slider 631 is fixedly connected to the outer surface of the extrusion rod 63, and the slider 631 is slidably connected to the sliding groove 613. A center rod 66 is fixedly connected to the outer surface of the bottom end of the rotating tube 65, a limit plate 67 is fixedly connected to the outer side of the bottom end of the center rod 66, and a trapezoidal block 653 is fixedly connected to the inner side of the driving groove 651. The oil return mechanism 5 includes a first oil return pipe 51 and a second oil return pipe 56. The bottom end of the first oil return pipe 51 is fixedly connected to the first rotating shell 54, and the top end of the second oil return pipe 56 is fixedly connected to the second rotating shell 55. A sealing ring 53 is installed between the second rotating shell 55 and the first rotating shell 54. The inner side of the second rotating shell 55 is rotatably connected to a rotating rod 52, and the top end of the rotating rod 52 passes through the first rotating shell 54.

[0029] In this embodiment, when the slider 631 slides along the extrusion rod 63, it moves along the slide groove 613, which can ensure that the extrusion rod 63 maintains stability during the pressing and resetting process. In addition, during the activity, the diameter of the extrusion plate 632 is larger than the inner diameter of the top tube 611, which can prevent the extrusion rod 63 from being separated from the outer tube 61 under the elastic action of the third spring 68. Moreover, during the activity, the presence of the mounting hole 62 can be connected with other brackets so as to play a reinforcing role during installation. The presence of the first oil return pipe 51 and the second oil return pipe 56 can conveniently connect the oil return pipeline. In this process, the presence of the rotating rod 52 can make the second rotating shell 55 and the first rotating shell 54 rotate relative to each other, thereby adjusting the angle between the first oil return pipe 51 and the second oil return pipe 56, and can also be adjusted to a suitable connection angle when installed in the interior of the car. Moreover, the presence of the sealing ring 53 can play a sealing role to ensure that there will be no leakage after rotation.

[0030] The function of adjusting the angle enables the pipe connection to adapt to different spatial layouts and location requirements, thereby improving the convenience of installation. Fixed pipe connections are prone to stress due to long-term vibration, leading to fatigue and damage. Connections with adjustable angles can absorb and alleviate these vibrations to a certain extent, extending the service life of pipes and connections.

[0031] Embodiment 3: According to Figure 1-7 As shown, the overflow mechanism 4 includes a connecting sleeve 43 and a second sleeve 44. A rotating groove 431 is provided at the top of the inner cavity of the connecting sleeve 43, and a first sleeve 42 is installed at the top of the inner cavity of the connecting sleeve 43. The bottom end of the first sleeve 42 is rotatably connected to the rotating groove 431. A first internal thread 421 is provided on the inner side of the top of the first sleeve 42. A third thread groove 442 is provided on the outer surface of the top of the second sleeve 44. A second internal thread 432 is provided at the top of the inner cavity of the connecting sleeve 43. The third thread groove 442 is threadedly connected to the second internal thread 432. A first connecting pipe 41 is installed in the inner cavity of the first sleeve 42, and an overflow hole 422 is provided at the bottom of the first sleeve 42. A second thread groove 412 is provided at the bottom of the first connecting pipe 41. A first internal thread 421 is provided at the top of the inner cavity of the first sleeve 42. The first internal thread 421 is threadedly connected to the second thread groove 412. A first thread groove 411 is provided at the top of the first connecting pipe 41. The top of the first thread groove 411 is threadedly connected to the oil collecting tank body 3. A third internal thread 441 is provided at the bottom end of the second sleeve 44, and a second connecting pipe 47 is installed at the bottom end of the inner cavity of the second sleeve 44, a fourth thread groove 471 is provided on the outer surface of the top end of the second connecting pipe 47, and a fifth thread groove 472 is provided on the outer surface of the bottom end of the second connecting pipe 47. The fourth thread groove 471 is threadedly connected with the third internal thread 441, an oil drain pipe 48 is installed in the inner cavity of the second sleeve 44, and oil drain holes 481 are provided at both ends of the oil drain pipe 48. Balls 45 are installed in the inner cavities of the second sleeve 44 and the first sleeve 42, and first springs 46 are installed on one side of the two balls 45. One end of one of the first springs 46 abuts against the first connecting pipe 41, and the bottom end of the other first spring 46 abuts against the second connecting pipe 47.

[0032] In this embodiment, the first thread groove 411 is connected to the overflow port of the oil collecting tank body 3, and then connected to the first sleeve 42 through the second thread groove 412 and the first internal thread 421. In addition, the bottom end of the first sleeve 42 is connected inside the connecting sleeve 43 through the rotating groove 431. In this process, the ball 45 can play a role in blocking the overflow hole 422. During the connection process, the connecting sleeve 43 can rotate with the first sleeve 42, and then when the second sleeve 44 is connected, the second internal thread 432 is connected to the third thread groove 442. During the connection process, the top of the oil drain pipe 48 is inserted into the overflow hole 422, and it will push the ball 45 inside the first sleeve 42, and the ball 45 will block the top of the oil drain pipe 48.

[0033] The ball 45 inside the second sleeve 44 will block the bottom of the oil drain pipe 48, and under the action of the first spring 46, the oil drain pipe 48 will be tightly squeezed. In addition, the bottom of the second sleeve 44 is connected to the fourth thread groove 471 through the third internal thread 441, thereby completing the installation of the second connecting pipe 47 to ensure the firmness during installation. After the oil drain pipe 48 is inserted into the overflow hole 422, the oil drain holes 481 at both ends of the oil drain pipe 48 can be used to drain oil and overflow, prevent liquid from overflowing due to excessive amount, and help regulate the pressure in the system. The existence of the oil drain hole 481 can limit the flow rate of the liquid, avoid a large amount of liquid being discharged through the overflow pipe instantly, thereby preventing the pressure in the system from dropping suddenly or the liquid level from fluctuating violently. It can also accurately control the discharge amount of excess liquid, prevent excessive or too fast discharge of liquid, and maintain the normal operation of the system. In addition, the flow limiting structure can also prevent external liquid or gas from flowing back into the system, and protect the safety of the system by limiting the flow direction.

[0034] The use method and working principle of the device: When installing the oil collecting tank body 3, the plug-in block 7 at the bottom of the oil collecting tank body 3 is used for plugging, and then the connection mechanism 6 on the top outside of the mounting ring 2 is used for connection. When plugging, the center rod 66 and the limit plate 67 are installed and connected with the automobile oil tank, thereby completing the preliminary plug-in connection.

[0035] After installation, when the squeezing rod 63 is pressed, the squeezing plate 632 can be driven to move together, so that the driving member 64 starts to move downward. When the driving member 64 moves downward, the squeezing plate 632 will slide inside the rotating tube 65, and during the sliding process, it will slide along the inclined trapezoidal block 653. At this time, the squeezing plate 632 will slide inside the driving groove 651, thereby squeezing the second spring 643 to compress it. Afterwards, after the squeezing plate 632 passes over the trapezoidal block 653, it will be pushed by the elastic action of the second spring 643 to continue to reset.

[0036] In addition, the squeezing rod 63 will also squeeze the third spring 68 during the descent process. When the squeezing plate 632 cannot continue to descend under the restriction of the rotating tube 65, the squeezing rod 63 must be loosened. Under the elastic action of the third spring 68, the squeezing rod 63 is reset, and the squeezing plate 632 can only move along the X-shaped structure route inside the rotating tube 65, thereby applying a force to the rotating tube 65 to rotate it. As the rotating tube 65 rotates, the center rod 66 will also be driven to rotate together. After the limit plate 67 rotates ninety degrees following the center rod 66, it will complete the transposition, so that after the oil collecting tank body 3 is plugged in and installed, it can be rotated so as to rotate ninety degrees in the original plug-in channel.

[0037] The first oil return pipe 51 and the second oil return pipe 56 can be conveniently connected to the oil return pipe. In this process, the second rotating shell 55 and the first rotating shell 54 can be relatively rotated by using the rotating rod 52, so as to adjust the angle between the first oil return pipe 51 and the second oil return pipe 56. This also enables the connection angle to be adjusted when installed inside the car. The presence of the sealing ring 53 can ensure that there will be no leakage after rotation.

[0038] When processing the overflow part of the oil collecting tank body 3, the first thread groove 411 is connected to the overflow port of the oil collecting tank body 3, and then the connection with the first sleeve 42 is completed through the second thread groove 412 and the first internal thread 421. The bottom end of the first sleeve 42 is connected inside the connecting sleeve 43 through the rotating groove 431. In this process, the ball 45 can effectively block the overflow hole 422. Then, when connecting the second sleeve 44, the second internal thread 432 is connected to the third thread groove 442. The top of the oil drain pipe 48 is inserted into the overflow hole 422, and the ball 45 inside the first sleeve 42 is pushed, and the ball 45 will block the top of the oil drain pipe 48.

[0039] The ball 45 inside the second sleeve 44 will block the bottom of the oil drain pipe 48, and the first spring 46 will squeeze the oil drain pipe 48 tightly. In addition, the bottom of the second sleeve 44 is connected to the fourth thread groove 471 through the third internal thread 441, thereby completing the installation of the second connecting pipe 47 to ensure the firmness of the installation. After the oil drain pipe 48 is inserted into the overflow hole 422, the oil drain holes 481 at both ends of the oil drain pipe 48 can achieve oil drainage, prevent the liquid from overflowing due to excessive amount, and can also help regulate the pressure in the system. The existence of the oil drain hole 481 can limit the flow rate of the liquid and prevent a large amount of liquid from being discharged through the overflow pipe instantly.
