Description

TECHNICAL FIELD

[0001] The utility model relates to a roller support technical field especially relates to a kind of double-arm roller support of bending handle. BACKGROUND

[0002] Double-arm roller support is a kind of stable mechanical device, usually made of solid metal material, its main function is to support and fix the roller, ensure that the roller remains stable during operation, avoid shaking or displacement, this support is widely used in various industrial fields requiring roller support and transmission, and some sports equipment.

[0003] At present, the handle and double-arm support of existing bending handle double-arm roller support are in the same plane, that is, the handle is parallel to the double arms of double support, which forms a certain angle between the handle and the wall when using horizontal roller brush to operate wall brushing, not only increases the operation difficulty of user, but also reduces work efficiency due to improper angle, and even causes fatigue of user's arm and shoulder. UTILITY MODEL CONTENT

[0004] The utility model aims at solving the shortcomings that handle and double-arm support of prior art are parallel, which forms a certain angle between handle and wall when using horizontal roller brush to operate wall brushing, not only increases the operation difficulty of user, but also reduces work efficiency due to improper angle, and even causes fatigue of user's arm and shoulder, and proposes a kind of double-arm roller support of bending handle.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A kind of double-arm roller support of bending handle, comprising:

[0007] Handle and U-shaped frame, the top of the handle is provided with a bayonet, the U-shaped frame is arranged in the bayonet of the top of handle, one side of the U-shaped frame is fixedly provided with a No.

[0008] In a possible design, a through hole is formed in the center of one side of the U-shaped frame, a hexagon socket head cap screw is arranged in the through hole, a threaded hole is formed in the center of the top of the handle, the hexagon socket head cap screw is matched with the threaded hole and can be threadedly connected.

[0009] In a possible design, a hole is formed in one side of the U-shaped frame, and a cross bolt is arranged in the hole, the cross bolt is threadedly connected with the No.

[0010] In a possible design, a plurality of curved surfaces are evenly distributed on the front and rear sides of the handle.

[0011] In one possible design, the plane at the handle gripping point forms a 45-degree angle with the plane containing the two arms of the U-shaped frame.

[0012] In this application, upon initial use, first select a U-shaped frame of suitable length, then gently insert the U-shaped frame into the latch at the top of the handle, ensuring both are secure but not impossible to disassemble. Align the through hole on the U-shaped frame with the threaded hole at the top of the handle. Next, remove the hex socket head cap screw, pass it through the through hole in the center of the U-shaped frame, and then rotate the hex socket head cap screw to connect it to the threaded hole in the handle, completing the secure connection between the U-shaped frame and the handle. Then, install one end of the roller brush on the outside of the first pin on the U-shaped frame, and insert the second pin into the other end of one end of the roller brush. Align the second pin with the hole on the U-shaped frame, and insert the cross bolt into the hole to connect it to the second pin. The hole is designed as a T-shaped hole, which will be embedded in the hole after the cross bolt is installed, achieving concealment after bolt installation. When the cross bolt is fully embedded in the hole, the installation between the roller brush and the U-shaped frame is completed.

[0013] The staff then gripped the handle, placing their fingers within the multiple curved surfaces on the front for a more comfortable hold and better control. They then pressed the roller brush against the wall, as... Figure Four As shown, since the plane of the handle grip is at a 45-degree angle to the plane of the U-shaped frame's arms, when the roller brush is horizontal to the wall, the angle between the handle and the wall is 45 degrees. During the use of the roller brush, in order to achieve a better painting effect, it is necessary to ensure that the pressure F_horizontal applied by the roller brush in the vertical direction of the wall reaches a certain value. The force applied to the horizontal roller brush is F, the angle between the handle and the wall is α, and the pressure F_horizontal applied by the roller brush in the vertical direction of the wall is F_horizontal = F × sinα. The larger the angle between the handle and the wall, the greater the pressure applied by the horizontal roller brush in the vertical direction of the wall, and the better the painting effect. This makes it more labor-saving during use. Furthermore, users can easily adjust the angle of the handle to adapt to different working environments or operational needs, thereby achieving the most labor-saving working method by changing the angle.

[0014] This utility model has the following beneficial effects:

[0015] This invention enhances operational flexibility and ease of use through the design of the handle and U-shaped frame, utilizing a 45-degree angle, allowing users to easily adapt to different work environments and operational needs, thereby improving work efficiency.
