[0023] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figure 1 As shown, this utility model proposes a right-angle shaft geared motor for a car wash machine, including a motor body 1, a reducer 2 mounted on the motor body 1, and an input bevel gear 4 integrally and coaxially fixed to the outer end of the motor shaft 3 of the motor body 1.

[0025] like Figure 2 As shown, the reducer 2 includes a housing 5, which consists of a shell 51 and a cover 52. The shell 51 is screwed to the motor body 1, and the cover 52 is screwed to the side of the shell 51. The housing 5 has two output ports 53, one on the side wall of the shell 51 and the other on the side wall of the cover 52. An input port 6 is provided on the end face of the housing 5 facing the motor body 1, through which the motor shaft 3 passes. A lower bearing 7 is interference-fitted into the input port 6, and the lower bearing 7 is fitted onto the motor shaft 3, supporting its rotation.

[0026] like Figure 2As shown, a primary drive shaft 8 is rotatably mounted inside the housing 5. Two primary grooves 9 are formed inside the housing 5, located on the outer casing 51 and the cover 52, respectively. Primary bearings 10 are interference-fitted into the primary grooves 9, and are respectively mounted on both ends of the primary drive shaft 8, supporting its rotation. A transmission bevel gear 11 and a primary output gear 12 are coaxially mounted on the primary drive shaft 8 via a key connection. The transmission bevel gear 11 meshes with the input bevel gear 4 of the motor shaft 3.

[0027] like Figure 2 As shown, a secondary drive shaft 13 is rotatably mounted inside the housing 5, located above the primary drive shaft 8. Two secondary grooves 14 are formed inside the housing 5, respectively on the housing 51 and the cover 52, and communicate with two output ports 53. Secondary bearings 15 are interference-fitted into the secondary grooves 14, and are respectively fitted onto both ends of the secondary drive shaft 13, supporting its rotation. A secondary input gear 16 is coaxially mounted on the secondary drive shaft 13 via a key connection, meshing with the primary output gear 12. Output shafts 17 are coaxially mounted on both ends of the secondary drive shaft 13 passing through the output ports 53. These two output shafts 17 serve as the two output ends of the right-angle shaft reduction motor used in this car wash machine, capable of connecting two associated loads.

[0028] This car wash machine uses a right-angle shaft geared motor with two output terminals, which can connect two associated loads without the need for an additional geared motor, thus reducing the cost of the car wash machine and saving installation space.

[0029] like Figure 3 and 4 As shown, an oil pipe 18 is installed on the top of the housing 5, and the oil pipe 18 is integrally fixed to the housing 51. The oil pipe 18 is located directly above the secondary input gear 16, and an oil cap 19 is installed on the oil pipe 18. A through-shaft bracket 20 and a positioning bracket 21 are fixedly connected to the outer wall of the oil pipe 18. A through-shaft hole 22 is opened on the side wall of the through-shaft bracket 20, and a through-shaft hole 23 is opened on the side wall of the positioning bracket 21. The through-shaft hole 22 and the through-shaft hole 23 are circular holes of the same diameter. Four positioning sliding holes 24 are evenly distributed circumferentially on the wall of the through-shaft hole 23. Two positioning sliding holes 24 are horizontally opened, and the other two positioning sliding holes 24 are vertically opened. The positioning sliding holes 24 penetrate the positioning bracket 21 laterally.

[0030] like Figure 3 and 4As shown, cylindrical positioning slide shafts 25 are transversely inserted into the first through-hole 22 and the second through-hole 23. The positioning slide shafts 25 are slidably engaged with the first through-hole 22 and the second through-hole 23, and can slide laterally under the pushing or pulling action of external forces. Positioning blocks 26 are fixedly connected to the axial surface of the positioning slide shaft 25. There are four positioning blocks 26, which are equidistantly distributed on the positioning slide shaft 25 with the center line of the positioning slide shaft 25 as the center. When the four positioning blocks 26 are respectively inserted into the four positioning slide holes 24, the positioning slide shaft 25 is restricted from rotation.

[0031] like Figure 3 and 4 As shown, a through-shaft plate 27 and a positioning plate 28 are rotatably mounted on the positioning slide shaft 25. The through-shaft plate 27 and the positioning plate 28 are fixedly connected to the side wall of the oil cap 19, allowing the oil cap 19 to rotate around the positioning slide shaft 25. A first rotating hole 29, which is circular, is provided on the side wall of the through-shaft plate 27 for the positioning slide shaft 25 to pass through and rotate in cooperation with it. A second rotating hole 30, which is also circular, is provided on the side wall of the positioning plate 28 for the positioning slide shaft 25 to pass through and rotate in cooperation with it. Four positioning locking holes 31 are evenly distributed circumferentially on the wall of the second rotating hole 30, and these holes 31 transversely penetrate the positioning plate 28. When the oil cap 19 is placed on the oil pipe 18, the four positioning holes 31 are aligned with the four positioning sliding holes 24 respectively; when the oil cap 19 is rotated upwards by ninety degrees, the four positioning holes 31 are aligned with the four positioning sliding holes 24 again.

[0032] like Figure 3 and 4 As shown, a circular reset plate 32 is fixedly connected to one end of the positioning slide shaft 25 near the through shaft bracket 20. The diameter of the reset plate 32 is larger than the diameter of the positioning slide shaft 25. A circular lock head end plate 33 is fixedly connected to one end of the positioning slide shaft 25 near the positioning bracket 21. The diameter of the lock head end plate 33 is larger than the diameter of the positioning slide shaft 25. The reset plate 32 and the lock head end plate 33 can restrict the positioning slide shaft 25 from sliding out of the through shaft hole 1 22 and the through shaft hole 23.

[0033] like Figure 3 and 4 As shown, a return spring 34 is fitted onto the positioning slide shaft 25. One end of the return spring 34 abuts against the return plate 32, and the other end abuts against the through shaft bracket 20. When the worker presses the return plate 32, causing it to move closer to the through shaft bracket 20, the return spring 34 is compressed. The spring force generated by the return spring 34 acts on the return plate 32, thereby driving the positioning slide shaft 25 back to its initial position.

[0034] In this embodiment, when the oil cap 19 is opened for use:

[0035] S1, when the worker presses the reset plate 32 and moves it closer to the shaft bracket 20, the reset spring 34 is compressed and the positioning slide 25 moves laterally until the positioning block 26 on the positioning slide 25 moves out of the positioning hole 31.

[0036] S2, rotate the oil cap 19 upwards by 90 degrees, and realign the four positioning holes 31 and the four positioning sliding holes 24. Then, the worker removes his hand from the reset plate 32. The spring force generated by the reset spring 34 will act on the reset plate 32, thereby pushing the reset plate 32 to move away from the through shaft bracket 20. The positioning sliding shaft 25 will then move laterally until the positioning block 26 on the positioning sliding shaft 25 is re-inserted into the positioning hole 31. At this time, the through shaft plate 27 and the positioning plate 28 are restricted from rotating, and the oil cap 19 remains open.

[0037] This car wash machine uses a right-angle shaft geared motor to add lubricating oil to the secondary input gear 16 through the oil pipe 18. The oil cap 19 on the oil pipe 18 is opened and closed by flipping, which effectively avoids the risk of losing the oil cap 19. Moreover, the oil cap 19 is locked when it is open or closed, and the oil cap 19 can stably maintain the open or closed state.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
