DETAILED DESCRIPTION

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a gearbox oil seal remover proposed by the utility model includes a central vertical rod 1 and an auxiliary disassembly mounting frame 2, a sliding seat is slidably provided on the central vertical rod 1, and adjusting rods 3 are rotatably provided at the openings on both sides of the sliding seat, and two groups of the adjusting rods 3 are fixedly connected to the outer sides of the bottom ends of the two groups of the adjusting rods 3, and also include a spring disassembly unit; the spring disassembly unit includes a telescopic rod 5 fixedly connected to the auxiliary disassembly mounting frame 2, a compression spring 6 is sleeved on the telescopic rod 5, and an elastic push plate 7 is fixedly connected to the upper part of the telescopic rod 5; the telescopic rod 5 is arranged in a T-shaped plate structure, and the raised part of the telescopic rod 5 cooperates with the sliding seat.

[0024] Sliding rods 8 are passed through both sides of the auxiliary disassembly and installation frame 2, and one end of the inner side of the sliding rod 8 is fixedly connected to a limiting block 9. A return spring 10 arranged on the outside of the auxiliary disassembly and installation frame 2 is sleeved on the sliding rod 8; the cross-section of the limiting block 9 is a combination of a quarter circle and a rectangle, and the arc surface of the limiting block 9 faces upward.

[0025] One outer end of the sliding rod 8 is fixedly connected to a limit housing 11, and a limit slot 12 is provided on the limit housing 11; a mounting plate 13 is fixedly connected to the side wall of the auxiliary disassembly mounting frame 2, and a limit plug plate 14 that is snap-fitted with the limit slot 12 is inserted on the mounting plate 13.

[0026] An adjusting screw 15 is screwed on the top of the auxiliary disassembly and installation frame 2 , and a pressure plate 16 arranged above the elastic push plate 7 is rotatably connected to the bottom end of the adjusting screw 15 .

[0027] When the user installs the device, the central vertical rod 1 is placed above the gearbox oil seal, and the adjusting rod 3 is rotated so that the disassembly claws 4 are inserted into the protruding parts of the oil seals on both sides, so as to facilitate the removal by force;

[0028] The auxiliary disassembly and installation frame 2 is installed on both sides of the central vertical rod 1, so that when the elastic push plate 7 is raised and lowered, the protruding part can cooperate with the sliding seat. First, the adjusting screw 15 is rotated and lowered, and the elastic push plate 7 is pressed down by the pressure plate 16. After the telescopic rod 5 is contracted, the compression spring 6 is compressed to accumulate mechanical energy;

[0029] During the downward movement of the elastic push plate 7, it contacts the arc surface of the limit block 9, pushing the sliding rod 8 to the side. When the elastic push plate 7 drops below the limit block 9, the limit housing 11 pushes the sliding rod 8, so that the limit block 9 is stuck above the elastic push plate 7, and the limit plug plate 14 is inserted into the limit slot 12 through the mounting plate 13 for limiting. At this time, the adjusting screw 15 can be rotated to rise and reset;

[0030] When the disassembly force is applied to the sliding seat, the limit plug plate 14 is pulled out from the limit housing 11, and the structure that loses the limit is pushed outward by the elastic potential energy of the reset spring 10, and the limit of the elastic push plate 7 is released. At this time, the elastic push plate 7 is quickly pushed upward by the elastic potential energy of the compression spring 6, and the elastic push plate 7 bounces the sliding seat upward, so that the sliding seat slides on the central vertical rod 1, and the strong mechanical energy cooperates with the disassembly claw 4 to lift and disassemble the gearbox oil seal;

[0031] The above is the entire process of using a gearbox oil seal remover.

[0032] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
