Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following embodiments and accompanying drawings.

The invention relates to a rotary type wax-polishing machine, which is based on the structure of a general wax-polishing machine and improves a traditional fixed handle into a rotary type movable handle. The handle of the rotary handle type waxing machine has two working modes of double locking and single locking. The double-locking working mode is that the handle is fixed with the shell at two opposite ends through the locking structure; the single locking mode is that the lock catches are released from the two ends of the handle, and the handle is locked by the lock catches after rotating to a set angle along the rotating shaft on the shell. At the moment, the distance between the far outer end of the ten-inch waxing disc and the rotating shaft of the handle is 20 cm, the distance between the handle rotated by 180 degrees and the rotating shaft of the handle is 30 cm, and the length of the arm is 40 cm, so that the maximum working range of the waxing machine in a single locking mode can be increased to 90 cm, and the requirement on waxing of a roof with the working distance of 80 cm is met.

The handle is in the double-locking state when normally operating, namely one end of the handle locks the handle and the shell through two groups of bevel teeth, and the other end of the handle is locked with the other end of the shell by one hoop type lock catch. At this time, the operation mode of the rotary handle type waxing machine is consistent with the operation mode of the common waxing machine and the waxing effect.

When waxing the working surface at a far height or a high height, the rotating handle needs to be set to be in a single locking state. During operation, the bevel gear locking buckle and the hoop type buckle of the handle are loosened at the same time, and the bevel gear locking buckle and the hoop type buckle are locked after the handle is rotated to a preset position within the range of 0-270 degrees. At this time, the rotary handle type waxing machine can fully exert the advantage of long-distance waxing.

As shown in FIG. 1, the rotary handle wax-polishing machine of the present embodiment has an exploded view.

The rotary handle type waxing machine of the embodiment is composed of a waxing machine main body and a rotary handle assembly arranged in the waxing machine main body. The waxing machine main part is including being motor drive assembly and shell electrical apparatus component group, and motor drive assembly includes motor 6, fan blade 7, eccentric block 8, bearing clamping ring 9, bearing 10, rotary chassis 11, sponge dish 12 and waxing cap 13 are constituteed. The shell electrical component group comprises a power line, a rectifier bridge, a circuit board, a fuse, a power switch 1, a hoop type lock catch 2 and a shell 3. The shell 3 is made of ABS, the hoop type lock catch 2, the bevel gear locking buckle 14, the cam rotating shaft 16, the rotating chassis 11 and the embedded bevel gear 4.1 are made of nylon; the sliding bevel gear 17 is made of metal or nylon; the handle 4 is engineering thermoplastic; the material of the waxing disc 12 is EVA foam.

The main body of the waxing machine of the present embodiment is identical to a common waxing machine, and the detailed discussion is only directed to the rotating handle assembly of the invention.

The rotary handle assembly comprises a handle 4, a long screw 5, a bevel gear locking buckle 14, a spring 15, an eccentric cam shaft 16, a sliding conical gear 17 and a fixing nut 18.

The cogged bevel gear 4.1 and the handle 4 are injection moulded or otherwise fixed at one end thereof, so that the cogged bevel gear 4.1 becomes an integral part of the handle 4. Firstly, the fixing nut 18 is placed in an inner hole of the sliding conical gear 17, then the eccentric cam shaft 16 penetrates through a radial inner hole of the sliding conical gear 17 and is installed at the other end of the handle 4, and finally the bevel gear locking buckle 14 is fixed on shafts at two ends of the eccentric cam shaft 16.

The left conical tooth B1 of the rotating shaft on the shell 3 and the conical tooth A1 on the sliding conical gear 17 form a first set of meshing teeth, and the right conical tooth B2 of the rotating shaft on the shell 3 and the conical tooth A2 on the embedded conical gear 4.1 form a second pair of meshing teeth.

The spring 15 is put into the inner hole on the left side of the rotating shaft of the shell 3, the preassembled rotating handle is assembled on the rotating shaft of the shell 3, the long screw 5 penetrates through one end of the rotating handle and is in threaded connection with the fixing nut 18 on the other end of the handle 4 through the inner hole of the rotating shaft on the shell 3, and thus the handle 4 is connected with the shell 3. The locking taper lock buckle 14 is released when locking the retaining nut 18, and requires that a suitable gap be maintained between the first set of engagement teeth a1, B1 and the second set of engagement teeth a2, B2.

When the bevel locking buckle 14 is retracted, i.e. it is in full abutment with the handle 4, the eccentric cam shaft 16 is rotated to the maximum eccentric position. The eccentric cam on the eccentric cam shaft 16 pushes the sliding bevel gear 17 forward until the first set of engagement teeth a1, B1 and the second pair of engagement teeth a2, B2 are fully engaged, so that the rotating handle set is locked with the housing. When the rotary handle group is in a locking state, the handle cannot rotate.

When the bevel locking buckle 14 is opened, i.e. the bevel locking buckle 14 is away from the handle 4, the eccentric cam shaft 16 rotates to the minimum eccentric position. The sliding bevel gear 17 is now moved backwards by the spring 15 until the first set of engagement teeth a1, B1 and the second pair of engagement teeth a2, B2 are fully disengaged, so that the rotary handle set is unlocked from the housing. When the rotary handle group is in an unlocked state, the handle can be rotated.

When the waxing machine works normally, the bevel gear locking buckle 14 and the hoop type lock catch 2 are adjusted to the locking position, and the handle 4 cannot rotate. If the waxing range needs to be increased, the bevel gear locking buckle 14 and the hoop type lock catch 2 need to be adjusted to the opening position, and the bevel gear locking buckle 14 and the hoop type lock catch 2 are locked after the handle 4 is rotated to the required position.

Fig. 2 is a schematic view showing the structure of the rotary handle type waxing machine according to the present embodiment (the handle is set to a locking position and an opening rotation position).
