[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1-5 As shown, a gasoline generator testing device includes a base 1, and a dynamometer 2 is provided on one side of the upper surface of the base 1.

[0027] An electric guide rail 4 is fixedly installed on the other side of the upper surface of the base 1. A movable seat 5 is fixedly installed on the moving end of the electric guide rail 4. A groove 6 is opened in the middle of the upper surface of the movable seat 5. Two sliders 7 are slidably arranged in the groove 6. A movable plate 8 is fixedly installed on the upper surface of each slider 7. A movable groove 9 is opened on the upper surface of each movable plate 8. Two movable blocks 10 are slidably arranged in each movable groove 9. A threaded hole 11 is opened on the upper surface of each movable block 10.

[0028] Each movable block 10 has a common mounting base 12 on its upper surface. A motor 13 is provided on one side of the mounting base 12. Several bolts 14 are provided through the bottom of the mounting base 12. The lower end of each bolt 14 is threaded into the corresponding threaded hole 11.

[0029] The operator controls two sliders 7 to move along the slide groove 6, causing the threaded hole 11 to move along the X-axis. Then, the operator controls two moving blocks 10 to move along the moving groove 9, causing the threaded hole 11 to move along the Y-axis. The operator then places the mounting base 12 on the upper surface of the moving block 10. The operator then tightens the bolt 14, so that the lower end of the bolt 14 engages with the corresponding threaded hole 11, thereby fixing the motor 13. This allows the operator to adjust the position of the threaded hole 11 according to the mounting base 12 of the motor 13 of the corresponding specification, thus facilitating the installation of mounting bases 12 of different specifications.

[0030] In another embodiment of the present invention, a bidirectional threaded rod 15 is rotatably installed between the two sides of the inner wall of the slide groove 6, and two sliders 7 are respectively threaded on both sides of the body of the bidirectional threaded rod 15.

[0031] One end of the bidirectional threaded rod 15 passes through the movable seat 5 and is fixedly mounted with a rotating wheel 16.

[0032] The operator rotates the rotating wheel 16, which drives the bidirectional threaded rod 15 to rotate. The rotating bidirectional threaded rod 15 drives the two sliders 7 to move along the slide groove 6 by the threaded advance.

[0033] In another embodiment of the present invention, a limiting groove 17 is provided through the inner wall of the two sliding grooves 6 on opposite sides, and two limiting blocks 18 are slidably arranged in the two limiting grooves 17, with each limiting block 18 being fixedly installed on one side of the corresponding slider 7.

[0034] By setting a limit block 18, the slider 7 is prevented from disengaging from the slide groove 6 when it moves.

[0035] In another embodiment of the present invention, each limiting block 18 has a connecting groove 19 on the surface of the side close to the corresponding limiting groove 17, and a connecting block 20 is fixedly installed in each connecting groove 19. A top rod 21 is slidably arranged on the opposite side of adjacent connecting blocks 20, and a first arc-shaped block 22 is fixedly installed on the opposite end of adjacent top rods 21.

[0036] Each connecting groove 19 has a clearance hole 23 through both sides of its inner wall. Each push rod 21 is inserted into the corresponding clearance hole 23. Each limiting block 18 has a positioning frame 24 fixedly installed on the side near the corresponding limiting groove 17. Each positioning frame 24 has a threaded post 25 rotatably installed through one side of its surface. Each threaded post 25 has a second arc-shaped block 26 fixedly installed at one end and a handwheel 27 fixedly installed at the other end.

[0037] After the moving block 10 moves to the corresponding position, the operator turns the handwheel 27, which drives the threaded column 25 to move relative to the positioning frame 24 while rotating. Under the pushing action of the second arc block 26, the first arc block 22 drives the second arc block 26 and the top rod 21 to move, so that one end of the top rod 21 is pressed against the inner wall of the limiting groove 17, thereby preventing the motor 13 from deviating during the test.

[0038] In another embodiment of this utility model, a limiting ring 28 is sleeved on one side of each top rod 21, and a spring 29 is sleeved on the side of each top rod 21 near the corresponding limiting ring 28.

[0039] After the operator controls the second arc block 26 to reset, the push rod 21 resets under the elastic force of the spring 29, eliminating the need for manual reset and reducing the workload of the operator.

[0040] In another embodiment of the present invention, each dynamometer 2 output end is fitted with a first external toothed ring 30, the motor 13 output end passes through the mounting base 12 and is fitted with a second external toothed ring 31, and the surfaces of the first external toothed ring 30 and the second external toothed ring 31 are jointly fitted with a toothed strip 32.

[0041] After the toothed belt 32 is fitted onto the surfaces of the first outer toothed ring 30 and the second outer toothed ring 31, the operator starts the electric guide rail 4 to move the moving seat 5, tightening the toothed belt 32. Then the operator starts the motor 13, causing the first outer toothed ring 30 and the second outer toothed ring 31 to rotate, allowing the dynamometer 2 to test the motor 13.

[0042] In another embodiment of this utility model, two crossbars 33 are fixedly installed on one side of the inner wall of the base 1, and sliding sleeves 3 are fixedly installed on both sides of the lower surface of the movable seat 5. Each sliding sleeve 3 is slidably disposed on one side of the corresponding crossbar 33.

[0043] By moving the sliding sleeve 3 along the crossbar 33, the sliding sleeve 3 can support the moving seat 5, making it more stable when moving.

[0044] The working principle of this gasoline generator testing device:

[0045] In use, the operator controls the two sliders 7 to move along the slide groove 6, causing the threaded hole 11 to move along the X-axis. Then, the operator controls the two moving blocks 10 to move along the moving groove 9, causing the threaded hole 11 to move along the Y-axis. The operator then places the mounting base 12 on the upper surface of the moving block 10. The operator then tightens the bolt 14, so that the lower end of the bolt 14 engages with the corresponding threaded hole 11, thereby fixing the motor 13. This allows the operator to adjust the position of the threaded hole 11 according to the mounting base 12 of the motor 13 of the corresponding specification, thus facilitating the installation of mounting bases 12 of different specifications.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
