[0024] Example 1

[0025] refer to Figures 1-4 The generator protection device shown includes a base plate 1, an engine body 2, a gasoline filter 3, a first oil pipe, an L-shaped oil inlet pipe 4, and a second oil pipe 5. The device is characterized in that a connecting mechanism is provided between the L-shaped oil inlet pipe 4 and the second oil pipe 5, the connecting mechanism being used to connect the second oil pipe 5 to the L-shaped oil inlet pipe 4. A side plate 18 is fixedly mounted on the top of the base plate 1, and a mounting protection mechanism is provided on the top of the side plate 18 for replacing the mounting protection mechanism. An upper valve 14 is provided on the second oil pipe 5, and a lower valve 15 is provided on the L-shaped oil inlet pipe 4.

[0026] The connecting mechanism includes a connecting pipe 6. A sealing assembly is provided between the connecting pipe 6 and the L-shaped oil inlet pipe 4 and the second oil pipe 5. A fixing ring 8 is fixedly installed on the outer wall of the peripheral side of the connecting pipe 6. Both ends of the fixing ring 8 are slidably installed with lifting clamps 9 through limit assemblies. Two operating blocks 12 are fixedly installed on the outer walls of the peripheral sides of the two lifting clamps 9. A filter plate 13 is fixedly installed on the inner wall of the peripheral side of the connecting pipe 6. A bypass assembly is commonly provided between the L-shaped oil inlet pipe 4 and the second oil pipe 5.

[0027] The installation protection mechanism includes a dust cover 19, which is fixedly installed on the top of the side plate 18. A rotating hole is opened on the bottom inner wall of the dust cover 19, and a rotating shaft 20 is rotatably installed in the rotating hole. The rotating shaft 20 is provided with multiple groups of clamping components.

[0028] With the above structure, when the connecting pipe 6 needs to be replaced during use, first close the upper valve 14 and the lower valve 15, open the bypass assembly, so that the engine body 2 can work normally, and then squeeze the multiple operating blocks 12 to drive the two lifting clamps 9 to move toward each other, release the limit of the connecting pipe 6 and the second oil pipe 5 and the L-shaped oil inlet pipe 4, and then pull the connecting pipe 6 outward to drive the rotating shaft 20 to rotate under the action of the clamping assembly. After the connecting pipe 6 is disassembled, it is convenient to clean it, and then the connecting pipe 6 set on another clamping assembly is installed between the second oil pipe 5 and the L-shaped oil inlet pipe 4, thereby realizing the quick replacement function, simple operation, and greatly improving work efficiency.

[0029] Example 2

[0030] like Figure 3 As shown, the sealing assembly includes two sealing rings 7, which are fixedly installed on the top end of the L-shaped oil inlet pipe 4 and the bottom end of the second oil pipe 5 respectively. Sealing grooves are provided at both ends of the connecting pipe 6, and the two sealing rings 7 are respectively adapted to the two sealing grooves. This arrangement can improve the sealing function of the connection through the sealing ring 7.

[0031] Specifically, by providing a sealing ring 7 at the connection, the sealing function can be greatly improved, gasoline overflow can be prevented, and the use effect can be improved.

[0032] Example 3

[0033] like Figure 3 As shown, the limiting assembly includes two limiting shafts 10, and a limiting hole is opened at the end of the lifting clamp 9. One end of the two limiting shafts 10 is fixedly installed on the end of the fixing ring 8, and the other ends of the two limiting shafts 10 are respectively slidably installed in the two limiting holes. The lifting clamp 9 is slidably installed on the connecting pipe 6. Elastic units are provided on the two limiting shafts 10. With this arrangement, the sliding distance of the lifting clamp 9 can be limited by the limiting shaft 10 to prevent it from falling off.

[0034] Specifically, by providing two limiting shafts 10 , the lifting clamp ring 9 can slide on the two limiting shafts 10 to prevent it from falling off, and the limiting shafts 10 can prevent the lifting clamp ring 9 from rotating, thereby improving stability.

[0035] like Figure 3 As shown, the elastic unit includes a reset spring 11, which is sleeved on the limit shaft 10. One end of the reset spring 11 is fixedly mounted on the end of the fixing ring 8, and the other end of the reset spring 11 is fixedly mounted on the end of the lifting clamp 9. In this way, the reset spring 11 can automatically reset the lifting clamp 9 when the limit on the lifting clamp 9 is released.

[0036] Specifically, when the lifting clamp ring 9 is moved toward the fixing ring 8, the reset spring 11 will be squeezed. When the limit on the lifting clamp ring 9 is released, the elastic action of the reset spring 11 can drive it to achieve the reset function.

[0037] Example 4

[0038] like Figure 2 As shown, the bypass assembly includes a branch pipe 16, one end of the branch pipe 16 is connected to the second oil pipe 5, and the other end of the branch pipe 16 is connected to the L-shaped oil inlet pipe 4. A branch pipe valve 17 is provided on the branch pipe 16. This arrangement allows oil to be supplied through the branch pipe 16 when the connecting pipe 6 is replaced, thereby preventing the engine body 2 from stopping working.

[0039] Specifically, when replacing the connecting pipe 6, by closing the upper valve 14 and the lower valve 15 and opening the branch valve 17, gasoline enters the L-shaped oil pipe 4 through the second oil pipe 5 and the branch pipe 16 and is injected into the engine body 2 to enable it to continue working.

[0040] Example 5

[0041] like Figure 4As shown, the clamping assembly includes two arc-shaped clamping plates 23, and the outer wall of the circumference of the rotating shaft 20 is fixedly sleeved with a mounting ring 21, and the outer wall of the circumference of the mounting ring 21 is fixedly installed with two fixing plates 22. The two arc-shaped clamping plates 23 are respectively fixedly installed on the sides of the two fixing plates 22, and the two arc-shaped clamping plates 23 are adapted to the fixing ring 8. The two arc-shaped clamping plates 23 are connected by a connecting unit. With this arrangement, the clamping function of the two arc-shaped clamping plates 23 on the fixing ring 8 can be used to fix several connecting pipes 6, which is convenient for replacement operations.

[0042] Specifically, the fixing ring 8 is fixed by the arc-shaped clamping plate 23, so that when one of the connecting pipes 6 is rotated after being disassembled, the other connecting pipe 6 can be driven out of the dust cover 18 for easy installation.

[0043] like Figure 4 As shown, the connecting unit includes a fixing bolt 24, and circular holes are opened on the sides of the two arc-shaped clamps 23. The fixing bolts 24 are arranged in the two circular holes, and nuts are threadedly installed on the fixing bolts 24. In this way, the two arc-shaped clamps 23 can fix the fixing ring 8 through the threaded action of the fixing bolts 24 and the nuts.

[0044] Specifically, when the fixing ring 8 needs to be fixed, the nut is rotated to engage with the fixing bolt 24 through the action of the thread, and the two arc-shaped clamping plates 23 are squeezed to fix the fixing ring 8.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
