Description

Technical Field

[0001] This utility model relates to the field of roller brush technology, and in particular to a roller frame. Background Technology

[0002] A roller brush is a common painting tool, typically consisting of a roller, bushing, support, and handle. The roller holder usually has an adjustable track to accommodate rollers of different sizes, and it is secured with bolts.

[0003] These types of adjustment structures are mostly made of metal, resulting in a heavy end of the roller frame. When used with the extension rod, a large gripping force is required, and it is prone to shaking and inaccurate control, affecting the painting operation. Secondly, under the shaking during the painting operation and the lubrication of the paint, the fastening bolts may loosen, which in turn causes the roller to loosen, requiring multiple clamping and adjustment, affecting the continuous use of the device.

[0004] To address the above problems, a roller frame is proposed. Utility Model Content

[0005] The main purpose of this utility model is to provide a roller frame that solves the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A roller frame includes a handle rod, the top of which is integrally formed with a connecting frame, and the two ends of the connecting frame are provided with a non-through first mounting groove and a second mounting groove, and a bracket is detachably connected in the first mounting groove and the second mounting groove.

[0008] The bracket includes an L-shaped clamping rod, one end of which is provided with a guide rod that is slidably connected to the first mounting groove, and a snap-fit ​​rod formed on the clamping rod and snap-fitted to the second mounting groove is provided directly above the guide rod;

[0009] A roller brush is rotatably mounted between the clamping rods.

[0010] Furthermore, the length of the bracket is 29-60cm.

[0011] Furthermore, the latching rod is an elastic structure, and the diameter of the latching rod is smaller than the inner diameter of the second mounting groove.

[0012] Furthermore, the end of the latching rod that passes through the second mounting groove is formed with a latching protrusion, which is snapped into the outer wall of the second mounting groove. The diameter of the guide rod is the same as the inner diameter of the first mounting groove.

[0013] Furthermore, a rotating shaft is formed on the inner top of the clamping rod, and a rotating sleeve is rotatably mounted on the rotating shaft. A protruding ridge is formed on the outer wall of the rotating sleeve, and the protruding ridge is pressed and clamped against the inner wall of the roller brush.

[0014] Furthermore, an extension connecting sleeve with internal threads is embedded in the inner wall of the handle rod.

[0015] Furthermore, four buckle grooves are formed on the inner wall of the handle rod, and a buckle strip is formed on the outer wall of the extension connecting sleeve. The buckle strip is adapted to the buckle groove for snap-fit ​​installation.

[0016] The beneficial technical effects of this utility model are as follows:

[0017] This utility model adopts an integrated support structure, which can be adapted to install rollers of different sizes by prefabricating clamping rods of different lengths. The clamping rods are snapped into the first and second mounting slots and securely connected to the connecting frame through buckle rods and guide rods. This avoids the shaking caused by traditional bolt fastening during use, and also saves the work of installation and clamping, making it convenient and quick to use. At the same time, the entire device is made of lightweight plastic material, which greatly reduces the weight of the roller frame and facilitates high-altitude painting operations.

[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0024] like Figures 1-3As shown, this embodiment provides a roller frame including a handle rod (4). The top of the handle rod 4 is integrally formed with a connecting frame 3. The two ends of the connecting frame 3 are provided with a non-through first mounting groove 301 and a second mounting groove 302. A bracket 2 is detachably connected in the first mounting groove 301 and the second mounting groove 302. The bracket 2 includes an L-shaped clamping rod 204. One end of the clamping rod 204 is provided with a guide rod 202 that is slidably connected to the first mounting groove 301. A snap-fit ​​rod 203 is provided directly above the guide rod 202, formed on the clamping rod 204 and snap-fit ​​connected to the second mounting groove 302. A roller brush 1 is rotatably installed between the clamping rods 204.

[0025] In the above structure, the handle rod 4, the connecting frame 3, and the bracket 2 are all made of plastic and have no metal connectors, which greatly reduces the overall weight of the device and makes it easy to use.

[0026] The length of bracket 2 is 29-60cm. In the preferred embodiment, bracket 2 is usually set to a length of 9 inches, 14 inches and 18 inches, and is adapted to be installed on the connecting frame 3 in a completely replaceable manner.

[0027] The latching rod 203 is an elastic structure, and its diameter is smaller than the inner diameter of the second mounting groove 302. One end of the latching rod 203 passing through the second mounting groove 302 has a latching protrusion 203a, which is engaged with the outer wall of the second mounting groove 302. The guide rod 202 has the same diameter as the inner diameter of the first mounting groove 301. By pressing down on the latching protrusion 203a, the latching rod 203 tilts downwards within the second mounting groove 302, allowing the latching protrusion 203a to be removed from the second mounting groove 302, thus enabling the clamping rod 204 to be disassembled and replaced.

[0028] A rotating shaft 201 is formed on the inner side of the top of the clamping rod 204. A rotating sleeve is rotatably mounted on the rotating shaft 201. A protruding ridge is formed on the outer wall of the rotating sleeve. The protruding ridge is pressed and clamped against the inner wall of the roller brush 1. A through hole with a diameter larger than that of the rotating shaft 201 is passed through the center of the rotating sleeve. This through hole is used to support the rotation of the brush. After the rotating sleeve is installed on the rotating shaft 201, the distance between the rotating sleeve and the inner wall of the clamping rod 204 is 5mm to prevent the rotating sleeve from being blocked by paint and unable to rotate flexibly.

[0029] An extension connecting sleeve with internal threads is embedded in the inner wall of the handle rod 4, and the extension connecting sleeve is connected to the extension rod through the internal threads.

[0030] The inner wall of the handle rod 4 has four buckle grooves 401, and the outer wall of the extension connecting sleeve has a buckle strip. The buckle strip and the buckle grooves 401 are matched and snapped together.

[0031] The above structure makes the device lighter, which is convenient for lifting during painting operations. At the same time, the device is made of solid hard plastic, which can prevent it from breaking when dropped, and has good durability. In addition, the one-piece clamping arm replacement mode saves a lot of installation work compared to the traditional bolt and rail adjustment method, making it convenient to use.

[0032] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

[0033] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
