DETAILED DESCRIPTION

[0027] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0028] like Figures 1 to 5 As shown, an engine switching switch provided in this embodiment includes a knob 1, an upper cover plate 2, a mounting body 3 and a movable supporting mechanism 4; the upper cover plate 2 is buckled on the mounting body 3, and both the upper cover plate 2 and the mounting body 3 are provided with coaxial through holes, and the knob 1 is provided with a connecting shaft 11, and the connecting shaft 11 is movably fitted in the through holes of the upper cover plate 2 and the mounting body 3.

[0029] An annular clamping column 31 is provided on one side of the mounting body 3 close to the upper cover plate, and the annular clamping column 31 is coaxial with the through hole of the mounting body 3; a closed position clamping groove 311 and a plurality of gear position clamping grooves 312 are provided on one side of the annular clamping column 31 close to the upper cover plate, and the closed position clamping groove 311 penetrates the wall thickness of the annular clamping column along the radial direction of the annular clamping column 31, and each gear position clamping groove 312 penetrates the wall thickness of the annular clamping column along the radial direction of the annular clamping column 31. In this embodiment, after the closed position clamping groove 311 penetrates radially along the annular clamping column 31, two corresponding clamping openings are formed on the annular clamping column 31, and the two clamping openings are in the same diameter direction of the cross section of the annular clamping column 31; after each gear position clamping groove 312 penetrates radially along the annular clamping column 31, two corresponding clamping openings are formed on the annular clamping column 31, and the two clamping openings are in the same diameter direction of the cross section of the annular clamping column 31.

[0030] The movable supporting mechanism 4 includes a supporting ring 41 and a supporting spring 42. The supporting ring 41 is provided with two radially symmetrically arranged latching teeth 411, and the latching teeth 411 are movably arranged in the corresponding closed position latching groove 311 or the gear position latching groove 312; the supporting ring 41 and the supporting spring 42 are both sleeved on the connecting shaft 11, and the supporting ring 41 is axially slidably matched along the connecting shaft 11, and the two ends of the supporting spring 42 are respectively against the supporting ring 41 and the upper cover plate 2. When the knob 1 is turned, the connecting shaft 11 drives the supporting ring 41 to rotate, and the supporting ring 41 slides along the connecting shaft 11 while rotating, so that the latching teeth 411 of the supporting ring 41 are disengaged from the original closed position latching groove 311 or the gear position latching groove 312.

[0031] The technical solution is to design the support ring 41 to slide along the axial direction of the connecting shaft 11, and at the same time, under the action of the support spring 42, the latching teeth 411 of the support ring 41 are movably locked in the corresponding closed position slot 311 or the gear slot 312 in a free state, thereby effectively avoiding the phenomenon that the knob gear of the conversion switch is not obvious and the switching is not accurate, which is conducive to the normal operation of the engine and improves the practicality. When the knob 1 is turned, the knob 1 drives the connecting shaft 11 to rotate, and the connecting shaft 11 drives the support ring 41 to rotate. The support ring 41 rotates and slides along the connecting shaft 11, so that the latching teeth 411 of the support ring 41 are separated from the original closed position slot 311 or the gear slot 312; when the knob 1 is rotated to a specified position, the latching teeth 411 of the support ring 41 are automatically locked in the corresponding closed position slot 311 or the gear slot 312 under the action of the support spring 42, thereby effectively limiting the rotation of the connecting shaft 11 and the knob 1.

[0032] In order to facilitate the latching tooth 411 to slide into or out of the closing position latching slot 311 or the shift position latching slot 312 , the latching tooth 411 , the closing position latching slot 311 and the shift position latching slot 312 are all in an isosceles trapezoid, a triangle or an arcuate shape.

This design effectively prevents the support spring 42 from contacting and abrading the connecting shaft 11. A sleeve 22 is provided on the side of the upper cover plate 2 close to the mounting body, the sleeve 22 is coaxial with the through hole of the upper cover plate 2, and the support spring 42 is arranged in the sleeve 22. The design of the sleeve prevents external debris from falling into the working area of ​​the support spring 42.

[0034] The engine conversion switch also includes a connecting sleeve 5; the outer side of the connecting sleeve 5 is provided with at least one first slide groove 51 arranged along the axial direction thereof, the connecting sleeve 5 is movably fitted in the through hole of the mounting body 3, the supporting ring 41 is movably sleeved on the connecting sleeve 5, and the supporting ring 41 is provided with a first slide block 413 movably fitted at the position corresponding to the first slide groove; the inner side of the connecting sleeve 5 is provided with at least one second slide groove 52 arranged along the axial direction thereof, the connecting sleeve 5 is movably sleeved on the connecting shaft 11, and the connecting shaft 11 is provided with at least one strip slide block 111 along the axial direction thereof, the strip slide block 111 is in one-to-one correspondence with the second slide groove 52, and the strip slide block 111 is movably fitted in the corresponding second slide groove 52. The structural design of the connecting sleeve 5, the supporting ring 41 and the connecting shaft 11 satisfies that when the connecting shaft 11 drives the connecting sleeve 5 and the supporting ring 41 to rotate, the supporting ring 41 can also slide along the axial direction of the connecting sleeve 5. In this embodiment, in order to ensure the structural strength of the connecting sleeve 5, the first slide groove 51 and the second slide groove 52 are staggered. There are three second slide grooves 52 and four first slide grooves 51, and the four first slide grooves 51 are evenly distributed circumferentially.

[0035] In addition, the engine conversion switch also includes a lower cover plate 6 and an oil valve 7; the lower cover plate 7 is buckled on the mounting body 3, the upper cover plate 2 and the lower cover plate 6 are located on opposite sides of the mounting body 3, and the oil valve 7 is installed on the lower cover plate 6; the lower cover plate 6 is provided with a through hole, the through hole of the lower cover plate 6 is coaxial with the through hole of the upper cover plate 2, the connecting shaft 11 passes through the through holes of the upper cover plate 2, the mounting body 3 and the lower cover plate 6 in sequence and is connected to the oil valve 7, and the connecting shaft 11 is used to control the opening and closing and multi-gear adjustment of the oil valve 7. In this embodiment, the connecting sleeve 5 is movably arranged between the lower cover plate 6 and the mounting body 3.

[0036] Specifically, the oil valve 7 is provided with a control shaft 71 for opening and closing or multi-gear adjustment, the cross section of the control shaft 71 is square, the connecting shaft 11 is provided with a square hole along its axial direction to match the control shaft, and the control shaft 71 of the oil valve 7 is inserted into the square hole of the connecting shaft 11. The connection design of the connecting shaft 11 and the control shaft 71 of the oil valve 7 facilitates the disassembly of the connecting shaft 11 and the control shaft 71 of the oil valve 7.
