[0031] In one embodiment of this utility model, a manually adjustable wheel track floating turntable mechanism is disclosed, such as... Figure 1-4As shown, the system includes a chassis frame 1, a front wheel frame 2, and a rear wheel frame 3. The front wheel frame 2 and the rear wheel frame 3 are respectively installed on both sides of the chassis frame 1 and are adjustable. Specifically, an adjustment sleeve 11 is provided inside the chassis frame 1, and an adjustment rod 12 is provided inside the front wheel frame 2 on one side of the adjustment sleeve 11. One end of the adjustment rod 12 extends into the interior of the adjustment sleeve 11, and the adjustment rod 12 is slidably connected to the adjustment sleeve 11. A handle turntable 4 is provided outside the chassis frame 1, and a drive shaft 41 is installed at the bottom of the handle turntable 4. The bottom of the drive shaft 41 drives the adjustment rod 12 and the adjustment sleeve 11 to slide through a transmission component, thereby realizing the adjustable distance between the front wheel frame 2 and the rear wheel frame 3.

[0032] In this embodiment, the aforementioned transmission assembly includes a rotating part 5 and a driving part 6. The rotating part 5 is connected to the transmission shaft 41 and rotates in conjunction with the handle turntable 4.

More specifically, the rotating part 5 includes a main conical tooth 51, an auxiliary conical tooth 52, and a linkage shaft 53. The linkage shaft 53 is located inside the chassis frame 1. The main conical tooth 51 is fitted onto the surface of the linkage shaft 53.

The drive unit 6 includes a transmission conical tooth 61, a threaded rod 62, a linkage conical tooth 63, and a threaded sleeve 64. The transmission conical tooth 61 is disposed at the end of the linkage shaft 53 of the rotating part, and the linkage conical tooth 63 is disposed at one end of the threaded rod 62, and the transmission conical tooth 61 and the linkage conical tooth 63 mesh with each other. The threaded rod 62 is fixed to the outer wall of the adjusting sleeve 11 and is disposed along the sliding direction of the adjusting rod 12 and the adjusting sleeve 11. The threaded sleeve 64 is fixed to the outer wall of the adjusting rod 12, and the thread of the threaded sleeve 64 meshes with the thread of the threaded rod 62, thereby playing the role of power transmission.

[0033] In use, rotating the handle turntable 4 drives the transmission shaft 41 to rotate, which in turn drives the auxiliary bevel gear 52 to rotate. With the cooperation of the auxiliary bevel gear 52 and the main bevel gear 51, the auxiliary bevel gear 52 drives the main bevel gear 51 to rotate, which in turn drives the linkage shaft 53 to rotate. The linkage shaft 53 then drives the transmission bevel gear 61 to rotate. With the cooperation of the transmission bevel gear 61 and the linkage bevel gear 63, the transmission bevel gear 61 drives the linkage bevel gear 63 to rotate, and the linkage bevel gear 63 drives... The rotating threaded rod 62, in cooperation with the threaded sleeve 64, drives the threaded sleeve 64 to move horizontally. The threaded sleeve 64 then drives the adjusting rod 12 to move, and the adjusting rod 12 enters the interior of the adjusting sleeve 11. The adjusting rod 12 and the adjusting sleeve 11 adjust the distance between the front wheel frame 2 and the rear wheel frame 3, allowing for manual adjustment of the wheel track. This enables convenient manual adjustment of the wheel track using the floating turntable, increases the adjustment range of the wheel track, and improves the convenience of wheel track adjustment.

[0034] It should be noted that, as Figure 4 As shown, to ensure the balance of the front wheel frame 2 and the rear wheel frame 3 during adjustment, in this embodiment, two adjustment sleeves 11 are provided, located on both sides of the chassis frame 1 respectively, and two adjustment rods 12 are provided, fixed on both sides of the front wheel frame 2 respectively, with the adjustment rods 12 corresponding to the positions of the adjustment sleeves 11. The adjustment rods 12 extend into the interior of the adjustment sleeves 11 for sleeve engagement. Correspondingly, two sets of drive units 6 are provided, corresponding to the positions of the adjustment sleeves 11 and the adjustment rods 12 respectively. Specifically, transmission conical teeth 61 are respectively provided at both ends of the rotating part linkage shaft 53, and linkage conical teeth 63 are respectively provided at the ends of the two threaded rods 62.

The two threaded rods 62 are respectively fixed to the inner sides of the two adjustment sleeves 11, and the two threaded sleeves 64 are respectively fixed to the inner sides of the two adjustment rods 12. The threads of the threaded rods 62 on the same side mesh with the threads of the threaded sleeves 64 on the same side.

[0035] In addition, a thickened recessed frame 13 is installed on the outer wall of the chassis frame 1 on one side of the adjusting sleeve 11, and a thickened protruding strip 21 is provided on the outer wall of the front wheel frame 2 on one side of the thickened recessed frame 13.

The top of the spring 74 is connected to the pressure arm 71, and the bottom of the spring 74 is connected to the mounting base 72. The spring 74 provides elastic support.

[0038] In use, the pressure arm 71 is installed together with the chassis frame 1 via the card holder 72, and is movably connected to the card holder 72 via the connecting shaft 73. The spring 74 provides elastic support for the pressure arm 71, and the pressure arm 71 contacts the handle turntable 4. The pressure arm 71 acts as a brake on the handle turntable 4. When it is necessary to rotate the handle turntable 4, the pressure arm 71 is pressed down to disengage the pressure arm 71 from the handle turntable 4, and the handle turntable 4 can rotate freely. This realizes convenient braking of the manual wheelbase adjustment floating turntable and prevents accidental rotation of the manual wheelbase adjustment floating turntable.

[0039] Through the above embodiments, a manual wheel track adjustment floating turntable mechanism of this utility model is disclosed. In use, when it is necessary to adjust the wheel track of the front wheel frame 2 and the rear wheel frame 3, the pressure arm 71 is pressed down to disengage the pressure arm 71 from the handle turntable 4. The handle turntable 4 is rotated, and the distance between the adjusting rod 12 and the adjusting sleeve 11 is adjusted by the cooperation of the rotating part 5 and the driving part 6, so as to realize the manual adjustment of the wheel track of the front wheel frame 2 and the rear wheel frame 3. During use, the thickened concave frame 13 and the thickened convex strip 21 move synchronously with the adjusting rod 12 and the adjusting sleeve 11 to complete the use of the floating turntable.

[0041] 1. This utility model features a manual turntable, which, together with a rotating part and a driving part, allows the adjusting rod to enter the adjusting sleeve, thus enabling convenient manual adjustment of the wheel track with a floating turntable. This increases the adjustment range of the wheel track and improves the convenience of adjusting the wheel track.

[0042] 2. This utility model connects the thickened concave frame to the chassis frame, and the front wheel frame drives the thickened convex strip to move inside the thickened concave frame, thereby increasing the connection strength of the structure and improving the stability of the manually adjustable wheel track floating turntable during operation;
