Referring to fig. 1-6, an embodiment of the present invention is shown: a roller paint brush convenient to disassemble comprises a fixed sleeve 1 and a roller brush 14, a screw rod 2 is inserted into the upper end of the fixed sleeve 1, a nut 3 is sleeved on the screw rod 2, the lower end of the screw rod 2 is set to be square, the inside size of the fixed sleeve 1 is matched with the outside size of the lower end of the screw rod 2, the screw rod 2 is matched with the nut 3, the screw rod 2 cannot rotate in the fixed sleeve 1 due to the structure, but can stretch, so that when the nut 3 rotates, the screw rod 2 cannot be driven to rotate, and the screw rod 2 can be driven to stretch through thread matching, so that the height or the length of the roller brush 14 can be adjusted;

the screw nut 3 is arranged at the upper end of the fixed sleeve 1 through a bearing 4, the upper end of the screw nut 3 is fixedly welded with a first gear 5, and the first gear 5 is meshed with the second gear 6, the second gear 6 is fixedly arranged at the upper end of the connecting shaft 7, and the connecting shaft 7 is fixedly and vertically arranged inside the right end of the fixed sleeve 1 through a rotating sleeve, the lower end of the connecting shaft 7 is fixedly welded with a first bevel gear 8, and the first bevel gear 8 is meshed with the second bevel gear 9, the second bevel gear 9 is fixedly arranged at the left end of the rotating handle 10, the rotating handle 10 is arranged at the right end of the fixed sleeve 1 through a rotating sleeve, the upper end of the screw rod 2 is inserted at the lower end of the sleeve block 11, the upper end of the screw rod 2 is provided with external threads, the lower end of the sleeve block 11 is provided with a thread groove matched with the upper end of the screw rod 2, the structure enables the sleeve block 11 to be rotatably arranged at the upper end of the screw rod 2 or be disassembled by reversing;

the support frame 12 is fixedly welded at the upper end of the sleeve block 11, the insertion rod 13 is inserted into the left side of the upper end of the support frame 12, the outer side size of the left end of the insertion rod 13 is equal to the outer side size of the upper end of the support frame 12, the inner side of the support frame 12 is provided with a slot matched with the right end size of the insertion rod 13, the structure enables the right end of the insertion rod 13 to be inserted into the left end of the support frame 12, and the two ends of the roller brush 14 are limited through the left end of the insertion rod 13 and the right end of the support frame 12, so that the roller brush 14;

and the inserting rod 13 and the supporting frame 12 are sleeved with the roller brush 14, the springs 15 are symmetrically arranged inside the upper side and the lower side of the right end of the inserting rod 13, the ends, far away from each other, of the two sets of springs 15 are fixedly connected with the inner ends of the two sets of the embedding blocks 16 respectively, the embedding blocks 16 are embedded at the right end of the inserting rod 13, annular grooves are formed in the inner wall of the supporting frame 12 at equal intervals, the inner side sizes of the grooves are matched with the outer side sizes of the embedding blocks 16, the outer ends of the embedding blocks 16 are semicircular, the embedding blocks 16 are arranged on the inserting rod 13 through the springs 15 to be of a telescopic structure, the structure enables the round ends of the embedding blocks 16 to be retracted into the inserting rod 13 and compress the springs 15 when certain extrusion force is applied to the round ends of the embedding blocks 16, when the outer ends of the embedding blocks 16 are not blocked, the springs 15 in a compressed state can push the embedding blocks 16 outwards to be restored, when the embedding blocks 16 are positioned in, the left end of the inserted link 13 and the right end of the supporting frame 12 have different distances, so that the roller brushes 14 with different lengths can be installed in the device.

The working principle is as follows: when the device is used, as shown in figure 1, the roller brush 14 can be firstly stained with paint, then the roller brush 14 is used for coating, and when the height or the length of the roller brush 14 needs to be adjusted, the rotating handle 10 can be rotated in the forward direction, the rotating handle 10 can drive the first bevel gear 8 to rotate through the second bevel gear 9, the first bevel gear 8 can drive the second gear 6 to rotate through the connecting shaft 7, the second gear 6 can drive the screw nut 3 to rotate through the first gear 5, the screw nut 3 can rotate at the upper end of the fixed sleeve 1 through the bearing 4 and can be matched with the screw rod 2, so that the screw rod 2 extends out of the fixed sleeve 1, the length or the height of the roller brush 14 is changed, when the roller brush is withdrawn, only the rotating handle 10 needs to be rotated in the reverse direction, if the device is not needed, the sleeve block 11 can be rotated in the forward direction, so that the thread groove of the sleeve block 11 is matched and separated from the upper end thread of the screw, the whole device can be separated into two parts so as to be convenient to store or carry, in addition, only the sleeve block 11 is sleeved at the upper end of the screw rod 2 during installation, and the sleeve block 11 and the screw rod 2 are rotated in the direction through threads; the connection is tight, when the roller brush 14 needs to be replaced, the inserting rod 13 is pulled leftwards, the round ends of two groups of embedded blocks 16 on the right end of the inserting rod 13 are extruded to move towards the inside of the inserting rod 13, the spring 15 is extruded, after the embedded blocks 16 leave the circular groove in the support frame 12, the inserting rod 13 can be separated from the support frame 12, then the replaced roller brush 14 is sleeved on the support frame 12, then the right end of the inserting rod 13 is inserted into the left end of the support frame 12, the embedded blocks 16 are contracted towards the inside of the inserting rod 13 through extrusion, the spring 15 is extruded, after the embedded blocks 16 are collected into the inserting rod 13, the inserting rod 13 can be inserted into the support frame 12 without being blocked, and a plurality of groups of circular grooves of the support frame 12 are arranged at equal intervals, the depth of the inserting rod 13 into the support frame 12 can be adjusted according to the length of the installed roller brush 14, so that the interval between the left end of the inserting rod 13 and the right end of the support frame 12 can be, in addition, the insert 16 is only required to be aligned with the circular groove of the support frame 12, and after the insert 16 is aligned with the circular groove in the support frame 12, the spring 15 in a compressed state pushes the insert 16 to be inserted into the groove, so that the inserted rod 13 and the support frame 12 are locked.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
