DETAILED DESCRIPTION

[0018] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0019] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] like Figs. 1 to 4 As shown in the figure, the present invention provides a spline shaft with a quick disassembly and assembly structure, including a support rod 101 and a patterned column 102. The diameter of the patterned column 102 is smaller than the diameter of the support rod 101. The patterned column 102 is connected to the end of the support rod 101. A spline sleeve 2, a flange 3 and a drive shaft body 4 are slidably connected to the patterned column 102 in sequence. A drive component is connected to the drive shaft body 4. When the drive component rotates, the drive shaft body 4 drives the flange 3 to abut against and limit the spline sleeve 2.

[0021] Support rod 101 and patterned column 102 form a spline shaft;

[0022] The diameter of the patterned column 102 is smaller than the diameter of the support rod 101 so that when the spline sleeve 2 is connected to the patterned column 102, there is space for it to cooperate with the recess 6 extending from the support rod 101, and the spline sleeve 2 can rotate on the recess 6.

[0023] As a preferred embodiment of this utility model, the driving component includes a threaded rod 5, a recessed seat 6, a driving block, and a turntable 7. The recessed seat 6 is installed inside the support rod 101 and extends towards the end near the patterned column 102. The spline sleeve 2 is rotatably sleeved on the extended portion of the recessed seat 6. The threaded rod 5 is installed on the recessed seat 6 and is connected through the patterned column 102. The threaded rod 5 extends out of the patterned column 102. The turntable 7 is rotatably connected to the portion of the threaded rod 5 that extends out of the patterned column 102. The driving block is rotatably connected to the transmission shaft body 4 and is connected to the turntable 7. When the driving block rotates, the turntable 7 rotates on the threaded rod 5 and extends into the patterned column 102. The transmission shaft body 4 drives the flange 3 to abut and limit the spline sleeve 2.

[0024] The existing spline sleeve 2 is set in a slot on the patterned column 102 and then rotated by a retaining ring. This structure is relatively troublesome to disassemble. Therefore, the spline sleeve 2 is rotated and fitted onto the part of the recessed seat 6 that extends from the support rod 101, so that it can rotate. The driving block is used to drive the flange 3 to abut against the spline sleeve 2, so that the spline sleeve 2 can still rotate while being limited. Because the end of the spline sleeve 2 near the flange 3 is equipped with a rotating ring 12, the flange 3 abuts against the rotating ring 12 of the spline sleeve 2, and the spline sleeve 2 will not be unable to rotate due to compression.

[0025] As the utility model discloses, preferably, the driving block comprises a rotating knob 8, and an annular groove 9 is formed in the end of the transmission shaft body 4, and the rotating knob 8 is rotatably connected to the annular groove 9, and a connecting piece is connected to the rotating knob 8, and the rotating knob 8 is connected to the rotating disc 7 through the connecting piece.

[0026] The connecting piece is arranged so that the rotating knob 8 can better drive the rotating disc 7 to make vertical reciprocating motion on the threaded rod 5 when the rotating knob 8 rotates.

[0027] As the utility model discloses, preferably, the connecting piece comprises a plurality of connecting rods 13 arranged in a ring on the rotating knob 8, and the rotating knob 8 is inserted into the rotating disc 7 through the connecting rods 13, and when the rotating knob 8 rotates, the connecting rods 13 drive the rotating disc 7 to slide on the threaded rod 5.

[0028] The plurality of connecting rods 13 arranged in a ring on the rotating knob 8 have a gap in the middle, so that when the rotating disc 7 moves in the direction of the recess 6 on the threaded rod 5, the transmission shaft body 4 also moves in the direction of the recess 6 along with the rotating disc 7, at which time the gap can be used for the threaded rod 5 to extend into the gap, and the length of the connecting rod 13, that is, the depth of the gap, needs to meet the requirement that the flange plate 3 can abut against the spline sleeve 2, and the threaded rod 5 can be inserted, and the threaded rod 5 cannot abut against the rotating knob 8 when the flange plate 3 has not abutted against the spline sleeve 2, so that there is no space to drive the rotating disc 7 to move in the direction of the recess 6.

[0029] As the utility model discloses, preferably, a cavity 10 is formed in the patterned column 102, and the diameter of the cavity 10 is greater than that of the rotating disc 7, and when the rotating knob 8 rotates, the connecting rod 13 drives the rotating disc 7 to extend into the cavity 10 of the patterned column 102 on the threaded rod 5, and the flange plate 3 abuts against the spline sleeve 2.

[0030] The cavity 10 is arranged for the installation of the threaded rod 5, and the rotating disc 7 moves in the cavity 10 and does not affect the installation operation on the surface of the workpiece.

[0031] As the utility model discloses, preferably, the flange plate 3 is connected with a connecting column 11 in the direction close to the spline sleeve 2, and when the flange plate 3 moves a certain distance in the direction of the spline sleeve 2, the connecting column 11 is inserted into the spline sleeve 2.

[0032] The connecting column 11 is arranged so that when the flange plate 3 abuts against the spline sleeve 2, the connecting column 11 is inserted into the rotating ring 12, and the spline sleeve 2 is limited and tightly abutted on the supporting rod 101, thereby replacing the limiting structure of the existing clamping groove and clamping ring.

[0033] As the utility model discloses, preferably, the end of the spline sleeve 2 close to the flange plate 3 is rotatably connected with a rotating ring 12, and the connecting column 11 is inserted into the rotating ring 12.

[0034] The rotating ring 12 is limited for the spline sleeve 2 and can rotate at the same time, because the end of the spline sleeve 2 close to the flange 3 is installed with the rotating ring 12, the flange 3 abuts against the rotating ring 12 of the spline sleeve 2, the spline sleeve 2 cannot be intransitive because of extrusion;

[0035] The spline sleeve 2 is provided with an annular groove for the rotating ring 12 to be connected in the annular groove.
