Description

Technical Field

[0001] The utility model relates to a connection structure, in particular to a cleaning brush disc connection structure. Background Art

[0002] A cleaning brush is a tool used to clean stains on the surface of objects. Existing cleaning brushes all have a brush disc connector installed on the brush disc. The limit block on the brush disc connector is inserted into the positioning sleeve from the mounting hole of the positioning sleeve, and then rotated into the mounting groove. The support of the limit block is achieved through the mounting groove. The brush disc connector is then directly connected to the drive motor through a transmission mechanism. When in use, the drive motor drives the limit block on the brush disc connector to rotate clockwise or counterclockwise in the mounting groove of the positioning sleeve through the transmission mechanism, so that the brush disc drives the bristles to rotate clockwise or counterclockwise to clean the surface of the object. During the rotation and cleaning process of the above-mentioned brush disc, the limit block on the brush disc connector always rotates along the mounting groove, causing continuous friction between the limit block and the mounting groove, which is not only noisy but also requires a greater driving force to achieve.

[0029] like Figures 1 to 8 The cleaning brush disc connection structure shown in the figure includes a positioning sleeve 1 and a brush disc 2; a brush disc connector 3 is provided on one side of the brush disc 2; and bristles 11 are provided on the other side of the brush disc;

[0030] The inner wall of the positioning sleeve 1 is provided with a mounting hole 101, a mounting limit groove 102, a connecting channel 103 and a guide limit block 104. The mounting hole 101 passes through the top and bottom ends of the positioning sleeve 1. The shape of the mounting hole 102 matches the shape of the brush plate connector 3.

[0031] The mounting hole 101 is connected to the guide limit block 104 and the mounting limit slot 102 in sequence through the connecting channel 103; the guide limit block 104 is arranged between the mounting limit slot 102 and the mounting hole 101; and the top end of the guide limit block 104 is arranged higher than the bottom end of the mounting limit slot 102;

[0032] The brush plate connector 3 is inserted into the positioning sleeve 1 from the bottom end of the mounting hole 101, rotates along the connecting channel 103, passes through the guide limit block 104, and then enters the mounting limit groove 102;

[0033] A metal sheet 4 is provided on the upper portion of the brush disc connector 3 located in the installation limit groove 102 . The metal sheet 4 and the brush disc connector 3 are connected via a brush head shaft 5 . A shaft sleeve 6 is provided on the brush head shaft 5 .

[0034] The outer wall of the positioning sleeve 1 in the present application is provided with a connecting hole 105 , and the connecting hole 105 is connected to the transmission mechanism 10 .

[0035] When the cleaning brush disc connection structure of the present invention is in use, the bottom end of the self-positioning sleeve 1 mounting hole 101 matching the brush disc connection member 3 is inserted into the positioning sleeve 1. Since the shape of the mounting hole 101 matches the shape of the brush disc connection member 3, it is easy to quickly identify the matching installation position between the brush disc connection member 3 and the mounting hole 101, thereby improving the efficiency of inserting the brush disc connection member 3 into the positioning sleeve 1 from the mounting hole 102; since the mounting hole 101 is connected to the guide limit block 104 and the mounting limit groove 102 in sequence through the connecting channel 103, when the brush disc connection member 2 is inserted from the mounting hole 1 After the bottom end of 02 is inserted into the positioning sleeve 1, the brush disc connector 3 is rotated so that the brush disc connector 3 rotates along the connecting channel 103 and passes through the guide limit block 104 to the installation limit groove 102. The brush disc connector 3 is supported by the installation limit groove 102. Since the top of the guide limit block 104 is higher than the bottom end of the installation limit groove 102, the guide limit block 104 is used to limit the brush disc connector 3 in the installation limit groove 102, thereby preventing the brush disc connector 3 from falling out of the installation hole 102 during rotation, thereby improving the stability of the brush disc. After the brush disc connector 3 and the installation limit groove 102 are installed, a metal sheet 4 is arranged on the upper part of the brush disc connector 3 located in the installation limit groove 102, and the metal sheet 4 and the brush disc connector 3 are connected by a brush head shaft 5 to realize the limitation of the metal sheet 4 on the upper part of the brush disc connector 3. The setting of the shaft sleeve 6 and the brush head shaft 5 connect the metal sheet 4 and the brush disc connector 3 to provide stability, thereby preventing the brush disc connector 3 from falling out from the top of the installation limit groove 2, thereby ensuring the safety and stability of the brush disc during use.

[0036] The transmission mechanism 10 is driven by a driving motor to rotate. During the rotation process, the transmission mechanism 10 pushes the connecting card hole 105 in a clockwise or counterclockwise direction, thereby enabling the transmission mechanism to push the positioning sleeve 1 in a clockwise or counterclockwise direction. Since the positioning sleeve 1 and the brush disc connector 3 are connected through the brush head shaft 5, the positioning sleeve 1 finally drives the brush disc connector 3 and the brush disc 2 to push and rotate clockwise or counterclockwise, and the brush disc connector 3 drives the brush disc 2 to rotate clockwise and counterclockwise, and finally the brush disc 2 drives the bristles 11 to clean the surface of the object. The positioning sleeve of the utility model is connected to the brush disc connector and is connected to the transmission mechanism through the positioning sleeve, so that the transmission mechanism drives the positioning sleeve to rotate and then drives the brush disc connector and the brush disc to rotate to complete the cleaning work, effectively avoiding friction between the brush disc connector and the positioning sleeve, reducing noise generation, and also reducing driving force, saving energy, and improving user comfort.

[0037] As a preferred embodiment, the brush disc connector 3 in the present application includes a connecting column 301 and two mounting blocks 302, the two mounting blocks 302 are symmetrically arranged on both sides of one end of the connecting column 301, the other end of the connecting column 301 is connected to the brush disc 2, and the two mounting blocks 302 are spaced apart from the brush disc 2; a connecting hole 3011 is provided on the connecting column 301, and the brush head shaft 5 is connected to the connecting hole 3011 after passing through the metal sheet 4; there are two guide limit blocks 104 and two mounting limit grooves 102 respectively, and the two guide limit blocks 104 are symmetrically arranged in the positioning sleeve 1, and the two mounting limit grooves 102 are symmetrically arranged in the positioning sleeve 1.
