One end of the front column is in threaded connection with the front nut through a sealing gasket, and the other end of the front column is in threaded connection with the rear column; a slip ring is arranged in the front column, and a rotating mechanism is arranged in the rear column; the rotating mechanism comprises a rotating sleeve and a rear clamping cover.

Furthermore, one end of the rotary sleeve is in threaded connection with the rear nut through a sealing gasket and is fixedly connected with the rear clamping cover through a rear positioning piece; the outer wall of the rotary sleeve is rotatably connected with the inner wall of the rear column through a bearing I, a framework oil seal I, a bearing II and a framework oil seal II; the rear column is rotatably provided with a rear clamping cover.

Furthermore, the other end of the rotating sleeve is connected with a sliding ring through a sealing ring. The two ends of the slip ring are respectively soldered with a floatable power line. The floatable power line is sealed by the sealing pad and then penetrates out of the front clamping cover and the rear clamping cover.

Furthermore, the front column is fixedly connected with the front clamping cover through the front positioning piece, so that the front column and the front clamping cover are fixed.

Further, the front clamping cover is divided into two halves and fixed by a fastener. The rear clamping cover is divided into two halves and fixed by a fastener.

Compared with the prior art, the invention has the following beneficial effects:

1. the rear clamping cover of the rotating mechanism drives the rotating sleeve to rotate at 360 ℃, so that the twisted twist of the electric wire is untied in the working process, the cleaning robot can work normally, and the working efficiency is improved.

2. Sealing gasket is arranged at the end parts of the front column and the rotary sleeve, so that water vapor is prevented from invading the front column and the rotary sleeve, the power line conducting wire is prevented from contacting water to cause electric shock or short circuit tripping when meeting water leakage, and the use safety factor is improved.

3. The structure that sets up the skeleton oil blanket between rotatory sleeve outer wall and the back post inner wall is adopted, prevents further that silt, dust, aqueous vapor etc. from invading the bearing outward in, improves life.

Detailed Description

As shown in FIG. 1, the movable joint comprises a front column 6, a rear column 14 and a rotating mechanism 19.

As shown in fig. 2 and 3, one end of the front column 6 is screwed with the front nut 2 through the sealing gasket 3, and the other end is screwed with the rear column 14; a slip ring 7 is arranged in the front column 6, and a rotating mechanism 19 is arranged in the rear column 14. The rotating mechanism 19 comprises a rotating sleeve 9 and a rear clamping cover 15; one end of the rotating sleeve 9 is connected with the sliding ring 7 through a sealing ring 8. The other end of the rotary sleeve 9 is screwed with a rear nut 16 through the sealing gasket 3 and is fixedly connected with the rear clamping cover 15 through a rear positioning piece 18. The front post 6 is fixedly connected with the front clamping cover 4 through a front positioning piece 17. The floatable power line 1 penetrates through the front clamping cover 4 and the rear clamping cover 15 after being sealed by the sealing pad 3. Sealed pad 3 is set up at fore-stock 6 and the tip of rotatory sleeve 9, prevents that the aqueous vapor from invading fore-stock and rotatory sleeve, avoids the power cord wire to meet water electric leakage and leads to people to touch water and electrocute or short circuit tripping operation, improves application safety factor.

The outer wall of the rotary sleeve 9 is rotatably connected with the inner wall of the rear column 14 through a bearing I10, a framework oil seal I11, a bearing II 12 and a framework oil seal II 13; a rear clamping cover 15 is rotatably provided on the rear pillar 14. And the bearing I10 and the bearing II 12 are both POM bearings. And the framework oil seal I11 and the framework oil seal II 13 are TC framework oil seals. The structure that the framework oil seal is arranged between the outer wall of the rotary sleeve 9 and the inner wall of the rear column 14 is adopted, so that silt, dust, water vapor and the like are further prevented from invading the bearing from the outside, and the service life of the movable connector is prolonged.

The front clamping cover 4 is in two halves and is secured by fasteners 5. The rear clamping cover 15 is in two halves and is secured by fasteners 5. The fastener 5 is a self-tapping screw. Two halves are assembled, and the assembling construction speed is high.

As shown in fig. 4, the floatable power supply line 1 is soldered to both ends of the slip ring 7.

The working principle is as follows: the floatable power cord 1 is wound into a twist shape after the cleaning robot works for a long time. The front clamping cover 4 and the front column 6, and the front column 6 and the rear column 14 are fixed and can not rotate. The rear column 14 and the rear clamping cover 15 rotate, and the rear clamping cover 15 drives the rotating sleeve 9 to rotate at 360 ℃. After the cleaning robot rotates, the clamping cover 15 is loosened in a twisted shape, and the floatable power line 1 returns to be linear, so that the cleaning robot can work normally, and the working efficiency is improved.
