DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0027] A hand-held wall painting device comprises a telescopic handle 1, the top of the telescopic handle 1 is fixedly connected to an L-shaped support frame 2, a first connecting rod 201 is arranged at the top of the L-shaped support frame 2, a connecting member 3 is arranged at the left end of the first connecting rod 201, a second connecting rod 4 is arranged at the left end of the connecting member 3, a paint roller 5 is fixedly connected to the left end of the second connecting rod 4, the telescopic handle 1 cooperates with the L-shaped support frame 2, the telescopic handle 1 is extended and retracted to drive the paint roller 5 to rise and fall, the L-shaped support frame 2 and the paint roller 5 are connected by the connecting member 3, so that the paint roller 5 can be quickly disassembled;

[0028] First, the connecting member 3 includes a first ring 301, a spring 302, a second ring 303 and a fixing ring 304. The first ring 301 is fixedly connected to the outer side of the left end of the first connecting rod 201. The spring 302 is sleeved on the outer side of the left end of the first connecting rod 201 and is located at the left end of the first ring 301. The second ring 303 is sleeved on the outer side of the left end of the first connecting rod 201 and is located at the left end of the spring 302. The fixing ring 304 is fixedly connected to the outer side of the second ring 303. A spring 302 is placed in the middle of the ring 301 and the second ring 303. The spring 302 plays a role of expansion and contraction. Both ends of the spring 302 are fixedly connected to the first ring 301 and the second ring 303. The fixing ring 304 is fixedly connected to the outer side of the second ring 303. The second ring 303 is moved by pushing the fixing ring 304. The second ring 303 squeezes the spring 302 to generate displacement. When the fixing ring 304 is released, the spring 302 rebounds to reset the second ring 303.

[0029] Furthermore, the right end of the second connecting rod 4 is slidably connected to the inside of the left end of the first connecting rod 201, and the left end of the inside of the first connecting rod 201 is provided with a ball 305, and the ball 305 is slidably connected to the inside of the first connecting rod 201 and the second connecting rod 4. The connection between the second connecting rod 4 and the first connecting rod 201 is clamped together by multiple groups of movable balls 305, and the ball 305 slides inside the second connecting rod 4 and the first connecting rod 201. The second ring 303 squeezes the ball 305 so that the ball 305 enters the second connecting rod 4, so that the second connecting rod 4 and the first connecting rod 201 are clamped together, and the second ring 303 pushes backward to release the squeezing of the ball 305, and the ball 305 resets and leaves the inside of the second connecting rod 4, so that the second connecting rod 4 can be disassembled, and the second connecting rod 4 drives the paint roller 5 to be disassembled.

[0030] Among them, the right end of the spring 302 is fixedly connected to the left end of the first ring 301, the left end of the spring 302 is fixedly connected to the right end of the second ring 303, and the two ends of the spring 302 are fixedly connected to the first ring 301 and the second ring 303 respectively. The spring 302 can only move inside the first ring 301 and the second ring 303, and the spring 302 plays the role of expansion and contraction and reset inside the first ring 301 and the second ring 303.

[0031] Secondly, the right end of the first connecting rod 201 is rotatably connected to the L-shaped support frame 2. A cylindrical block 202 is provided inside the right end of the first connecting rod 201. The first connecting rod 201 drives the paint roller 5 to rotate through the connecting member 3 and the second connecting rod 4. The cylindrical block 202 stabilizes the rotation of the first connecting rod 201 to prevent the first connecting rod 201 from falling off.

[0032] Furthermore, the telescopic handle 1 includes a telescopic rod 101 and an outer rod 102. The top of the telescopic rod 101 is fixedly connected to the bottom of the L-shaped support frame 2, and the outer rod 102 is slidably connected to the outer side of the telescopic rod 101. The telescopic rod 101 can be telescoped to change its length. The telescopic rod 101 slides inside the outer rod 102. A sliding bar is provided on the outer side of the telescopic rod 101, so that the telescopic rod 101 has a limiting effect, so that the telescopic rod 101 can only slide up and down.

[0033] Furthermore, the internal thread connection of the telescopic rod 101 is connected with a threaded rod 103, and the bottom end of the threaded rod 103 is rotatably connected to the outer rod 102. The threaded rod 103 is threadedly connected to the inside of the telescopic rod 101. The rotation of the threaded rod 103 drives the telescopic rod 101 to move up and down. The bottom end of the threaded rod 103 is rotatably connected to the outer rod 102, so that the threaded rod 103 is not restricted when rotating. A semicircular groove is provided at the bottom end of the outer rod 102 to facilitate the rotation of the threaded rod 103 and to prevent the threaded rod 103 from being completely exposed to the outside, so that the thread is filled with dirt, affecting the use of the threaded rod 103.

[0034] Finally, an anti-slip sleeve 104 is fixedly connected to the outer side of the bottom end of the threaded rod 103. The anti-slip sleeve 104 makes it easier for the threaded rod 103 to be rotated by hand to prevent slipping. A semicircular groove is provided inside the bottom end of the outer rod 102 at a position corresponding to the anti-slip sleeve 104. An anti-slip handle 105 is provided on the outer side of the outer rod 102. The anti-slip handle 105 makes the painting device more stable when used to prevent the painting device from falling.

[0035] When the paint roller 5 is broken, the fixing ring 304 can be pushed, and the second ring 303 inside the fixing ring 304 compresses the spring 302. At this time, the ball 305 can slide out, and the second connecting rod 4 can be pulled out, and the paint roller 5 can be disassembled and replaced. At this time, the new paint roller 5 is inserted into the first connecting rod 201 through the second connecting rod 4, and the fixing ring 304 is loosened. At this time, the spring 302 pushes the second ring 303 to squeeze the ball 305 into the groove, thereby jamming the second connecting rod 4. When it is necessary to brush a higher place, the telescopic rod 101 is pushed up by rotating the threaded rod 103. A semicircular groove is provided at the bottom end of the outer rod 102, and the bottom end of the threaded rod 103 is rotatably connected to the bottom of the outer rod 102. The threaded rod 103 can be rotated by putting the hand into the semicircular groove to facilitate the extension and retraction of the telescopic rod 101. Compared with the existing painting device, the utility model can improve the overall practicality and convenience of the painting device through design.
