Therefore, the terms used here should not be simply understood as their names, but should be understood based on the meaning of the term and the overall context of the present disclosure.
[0039] Embodiment 1
[0040] As Figures 1 to 3As shown in the figure, a roller brush device for applying wall paint includes a brush rod 10 and a roller 20; the brush rod 10 has a cross bar portion 11, and the middle of the roller 20 has a perforation 21; one end of the cross bar portion 11 is provided with a movable baffle 12, and the other end of the cross bar portion 11 is provided with a positioning baffle 13; a rotary holding member 22 is fixedly arranged on the perforation 21, and the cross bar passes through the perforation 21 and is rotatably connected with the rotary holding member 22; the roller 20 is located between the movable baffle 12 and the positioning baffle 13; the movable baffle 12 is slidably connected with the cross bar portion 11; the positioning baffle 13 is detachably connected with the cross bar portion 11 through an insertion structure.
[0041] In this embodiment, an insertion tube 14 is arranged on the positioning baffle 13, one end of the cross bar portion 11 is inserted into the insertion tube 14, and the positioning baffle 13 and the cross bar portion 11 are detachably connected through the insertion tube 14.
[0042] In this embodiment, a reset mechanism is arranged on the brush rod 10, and the reset mechanism is used to drive the movable baffle 12 to reset.
[0043] Specifically, the reset mechanism includes a guide cylinder 30 and a reset spring 31; the guide cylinder 30 is configured to be fixedly connected with the brush rod 10; the reset spring 31 is movably sleeved on the outer wall of the guide cylinder 30; one end of the reset spring 31 is fixedly connected with the brush rod 10, and the other end of the reset spring 31 is fixedly connected with one side of the movable baffle 12.
[0044] During use, the movable baffle 12 can be pushed so that the thrust is transmitted to the positioning baffle 13 through the roller 20, causing the positioning baffle 13 to displace. After the positioning baffle 13 moves away from the roller, it is convenient to further disassemble the positioning baffle 13.
[0045] In order to facilitate pushing the movable baffle 12, a finger hole 15 is arranged on the brush rod 10, and the finger hole 15 is located on one side of the movable baffle 12.
[0046] When pushing the movable baffle 12, one hand can hold the brush rod 10 through the finger hole 15, and the other hand pushes the movable baffle 12, which is convenient for disassembly and assembly.
[0047] In this embodiment, the rotary holding member 22 is a bearing.
[0048] Specifically, the inner ring of the bearing is in clearance fit with the cross bar portion, and the outer ring of the bearing is fixedly connected with the roller 20.
[0049] In this embodiment, the outer diameter of the insertion tube 14 gradually decreases along the direction away from the positioning baffle 13.
[0050] Furthermore, a guiding hole is provided in the middle of the movable baffle 12, and the movable baffle 12 and the crossbar part 11 are slidably connected through the guiding hole; on the other side of the movable baffle 12, there is a guiding tube 17, and the guiding tube 17 communicates with the guiding hole, and the outer diameter of the guiding tube 17 gradually decreases in the direction away from the movable baffle 12.
[0051] The insertion tube 14 and the guiding tube 17 adopt a tapered structure, and the outer diameters of the small-diameter ends of the insertion tube 14 and the guiding tube 17 are both less than the aperture of the perforation 21. The insertion tube 14 and the guiding tube 17 can be conveniently inserted into the perforation 21.
[0052] Since the insertion tube 14 and the guiding tube 17 adopt a tapered structure, even if the surfaces of the insertion tube 14 and the guiding tube 17 are covered with cured paint, it does not affect the use, and the adaptability is good.
[0053] In this embodiment, the positioning baffle 13 and the crossbar part 11 are connected by a plug-in structure. The distance between the movable baffle 12 and the positioning baffle 13 can be adjusted by adjusting the depth of the crossbar part 11 inserted into the insertion tube 14. Therefore, it has good applicability to drums 20 of different lengths and can meet drums of a variety of different lengths.
[0054] Embodiment 2
[0055] This embodiment provides a paint roller device for applying wall paint, and the difference from Embodiment 1 is that: the rotary retaining member 22 is a self-lubricating plastic ring.
[0056] Specifically, the self-lubricating plastic ring is made of POM material, and the outer ring surface of the self-lubricating plastic ring is fixedly connected to the hole wall of the perforation; the ring hole in the middle of the self-lubricating plastic ring is in clearance fit with the crossbar part.
[0057] Embodiment 3
[0058] As Figure 4 shown, this embodiment provides a paint roller device for applying wall paint, and the difference from Embodiment 1 is that: a pull ring 16 is provided on the positioning baffle 13.
[0059] When disassembling, both hands can respectively hold the pull ring 16 and the finger hole 15 to pull out the positioning baffle 13, and the disassembly and assembly are very convenient.
[0060] The subject matter disclosed above will be considered illustrative and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other embodiments that fall within the true spirit and scope of the inventive concept. Accordingly, to the maximum extent permitted by law, the scope will be determined by the broadest permissible interpretation of the appended claims and their equivalents, and should not be restricted or limited by the foregoing detailed description.
