The drive wheel seat is very critical for the installation and use of the machine.

A buffer groove is formed on both sides of the bottom of the fixing plate. The utility model uses a first spring to push a movable baffle downward, which can drive the bottom of the support rod into contact with a fixing ring, providing downward support for the mounting rod. Furthermore, the first spring and the damping block work together to absorb and dissipate the vibration energy transmitted from the drive wheel to the interior of the vibration damping frame, thereby resolving the problem that existing drive wheel seats are unable to process the vibration energy generated by the drive wheel.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figures 1-6 As shown, a novel driving wheel seat includes a fixed seat 1, a movable hole is opened in the middle of the upper end of the fixed seat 1, and a mounting rod 4 is movably connected to the inner wall of the movable hole. A limiting mechanism 2 is fixedly installed on the left and right parts of the upper end of the fixed seat 1, and a buffer assembly 3 is fixedly installed on the bottom of the outer wall of the mounting rod 4;

[0029] The limiting mechanism 2 includes two rectangular accommodating sleeves 21, the lower ends of the two accommodating sleeves 21 are fixedly installed on the left and right parts of the upper end of the fixed seat 1, the inner walls of the two accommodating sleeves 21 are slidably connected with movable plates 22, and the opposite sides of the two movable plates 22 are fixedly installed with limiting rods 23, and the left and right positions of the top of the outer wall of the mounting rod 4 are provided with limiting grooves, and the upper and lower ends of the two limiting rods 23 are close to each other and movably sleeved with the inner walls of the two limiting grooves, and the upper ends of the two movable plates 22 are fixedly installed with connecting frames 24, and the front parts of the two connecting frames 24 are fixedly installed with racks 25. Two mounting plates 26 are fixedly installed on the front of the upper end of the fixed seat 1, and the opposite sides of the two mounting plates 26 are rotatably connected with gears 27. The two racks 25 are arranged opposite to each other and are located on the left and right sides of the gear 27, and the opposite sides of the two racks 25 are meshed with the outer surface of the gear 27;

[0030] The buffer assembly 3 includes a movable plate 31, the inner wall of the movable plate 31 is slidably connected to the bottom of the outer wall of the mounting rod 4, the left and right parts of the lower end of the fixed seat 1 are fixedly installed with mounting sleeves 32, the inner wall tops of the two mounting sleeves 32 are fixedly installed with damping blocks 33, the left and right parts of the upper end of the movable plate 31 are fixedly installed with push columns 34, the outer walls of the two push columns 34 are slidably connected to the inner walls of the two mounting sleeves 32, the bottoms of the inner walls of the two mounting sleeves 32 are fixedly installed with guide rods 35, the upper ends of the two push columns 34 are provided with cylindrical slide grooves that match the two guide rods 35, the outer walls of the two guide rods 35 are movably sleeved with buffer springs 36, the lower ends of the two buffer springs 36 are fixedly connected to the upper ends of the two push columns 34, the upper ends of the two buffer springs 36 are fixedly connected to the lower ends of the two damping blocks 33, and the left and right parts of the lower end of the movable plate 31 are movably connected with an adjustment mechanism 37.

[0031] The mounting rod 4 can be limited by the limiting mechanism 2, making it easy to disassemble the drive wheel installed at the bottom of the drive wheel seat. By moving one connecting frame 24 at will, the two racks 25 will move relative to each other due to engagement with the gear 27, causing the two movable plates 22 to slide in the corresponding accommodating sleeve 21 and move away from or closer to each other. When the two limiting rods 23 approach each other, they will be inserted into the corresponding limiting grooves, thereby limiting the mounting rod 4. With this structure, only one of the connecting frames 24 needs to be moved to adjust the positions of the two limiting rods 23 at the same time. This is convenient, fast and highly practical. The buffer assembly 3 can play a buffering and vibration-reducing role when the drive wheel at the bottom of the mounting rod 4 is subjected to force. The mounting rod 4 will be subjected to forces in the up and down directions. When the mounting rod 4 is impacted or vibrated, the movable plate 31 compresses the buffer spring 36 through the push column 34, reducing the impact of the impact and vibration on the overall structure, and the damping block 33 will absorb and eliminate the vibration energy of the buffer spring 36. When the drive wheel seat needs to bear loads of varying weights, rotating the adjustment screw 372 drives the movable plate 31 up and down, allowing the two push pins 34 to quickly adjust the compression of the two buffer springs 36. This allows the vibration amplitude to be adjusted according to the driving wheel's travel path, thus expanding its applicability. This structure offers diverse functions and wide applicability.

[0032] like Figure 5 As shown, the upper ends of the two accommodating sleeves 21 are provided with movable grooves that match the two connecting frames 24, and the sides of the two movable plates 22 that are away from each other are fixedly installed with tension springs 28, and the ends of the two tension springs 28 that are away from each other are fixedly connected to the sides of the inner walls of the two accommodating sleeves 21 that are away from each other.

[0033] The tension spring 28 provides a restoring force for the movable plate 22 , thereby ensuring the stability and reliability of the limiting mechanism 2 .

[0034] like Figure 3 and Figure 6As shown, the adjustment mechanism 37 includes a fixed plate 371, the inner wall of the fixed plate 371 is fixedly connected to the bottom of the outer wall of the mounting rod 4, the fixed plate 371 is located below the movable plate 31, and the lower right end of the fixed plate 371 is threadedly connected to an adjusting screw 372 that passes through the bottom of the fixed plate 371, and the upper end of the adjusting screw 372 is rotatably connected to the lower right end of the movable plate 31.

[0035] When the driving wheel seat needs to bear loads of different weights, the adjusting screw 372 is rotated, and the adjusting screw 372 will drive the movable plate 31 to move up and down, so that the two push pins 34 can quickly adjust the compression amount of the two buffer springs 36, and then the corresponding vibration amplitude can be adjusted according to the condition of the driving wheel driving path, thereby expanding the scope of application.

[0036] like Figure 2 As shown, the left lower end of the fixed plate 371 is slidably connected to a slide rod 373 that passes through the bottom of the fixed plate 371 , and the upper end of the slide rod 373 is fixedly connected to the left lower end of the movable plate 31 .

[0037] The slide bar 373 limits the movement of the movable plate 31 .

[0038] like Figure 1 and Figure 6 As shown, slide bars 38 are fixedly installed at the left and right positions of the bottom of the outer wall of the mounting rod 4. The two slide bars 38 are both located above the fixed plate 371. The left and right parts of the inner wall of the movable plate 31 are provided with sliding grooves matching the two slide bars 38.

[0039] The cooperation between the slide bar 38 and the slide groove has a guiding effect on the movement of the movable plate 31.

[0040] like Figure 1 As shown, a support frame 11 is fixedly installed at the edges of the left and right parts of the upper end of the fixing base 1, and a mounting frame 12 is fixedly installed at the middle part of the upper end of the support frame 11.

[0041] The mounting frame 12 is used to fix and install the driving wheel seat as a whole so that it is connected to other components by bolts.

[0042] like Figure 2 and Figure 3 As shown, a limiting sleeve 13 is fixedly installed at the middle position of the top of the inner wall of the support frame 11, and the top of the outer wall of the mounting rod 4 is slidably connected to the left and right parts of the inner wall of the limiting sleeve 13.

[0043] The limiting sleeve 13 limits the movement of the installation rod 4 and protects the installation rod 4.

[0044] The working principle of this utility model is as follows: by randomly moving one connecting frame 24, the mounting rod 4 is inserted into the movable hole, and its top slides into the limiting sleeve 13. The two racks 25 engage with the gear 27 and move relative to each other, causing the two movable plates 22 to slide in the corresponding receiving sleeves 21 and move away from or closer to each other. When the two limiting rods 23 approach each other, they insert into the corresponding limiting grooves, thereby limiting the mounting rod 4. This structure only requires moving one of the connecting frames 24 to adjust the position of both limiting rods 23 simultaneously. It is convenient, fast, and highly practical, and it is also easy to remove the drive wheel installed at the bottom of the mounting rod 4.

[0045] When the drive wheel moves, the mounting rod 4 is subjected to vertical forces. When impacted or vibrated, the movable plate 31 compresses the buffer spring 36 via the push pin 34, reducing the impact and vibration on the overall structure. The damping block 33 absorbs and dissipates the vibration energy of the buffer spring 36. If the drive wheel seat needs to carry loads of varying weights, rotating the adjustment screw 372 drives the movable plate 31 up and down, allowing the two push pins 34 to quickly adjust the compression of the two buffer springs 36. This allows the vibration amplitude to be adjusted according to the conditions of the drive wheel's travel path, thus expanding its applicability. This structure offers diverse functions and wide applicability.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
