[0015] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows: Example: Refer to Figure 1-Figure 5As shown, a quick-install disc brush device of the present embodiment includes a disc brush body 1 and a motor 3 for driving the disc brush body 1 to rotate, wherein the motor 3 has a self-locking function. When the motor 3 stops running, the transmission shaft 31 will be locked to prevent the transmission shaft 31 from rotating when the disc brush body 1 is rotated, thereby facilitating the staff to rotate and disassemble the disc brush body 1.
[0016] A connecting base 2 is provided in the middle of the upper end of the disc brush body 1. The connecting base 2 is located at the bottom of the motor 3 and is transmission-connected to the motor 3 via a connecting shaft 4. The connecting base 2 and the connecting shaft 4 are threadedly connected and locked in position by a locking assembly. The locking assembly includes a locking pin 23 and a locking hole 41 that plugs into the locking pin 23. The locking pin 23 is movably mounted in the middle of the inner side of the connecting base 2. The locking hole 41 is opened in the middle of the bottom end of the connecting shaft 4. A pull rod 25 is provided on the back of the locking pin 23. The pull rod 25 is movably mounted in the middle of the inner side of the connecting base 2, and its head end extends out of the connecting base 2. The outer periphery of the pull rod 25 is sheathed with a spring 24, which is mounted in the middle of the inner side of the connecting base 2 and located behind the locking pin 23. A threaded sleeve 22 is provided in the middle of the upper end of the connecting base 2. The upper end of the connecting shaft 4 is provided with an external thread structure 42, which is threadedly connected to the threaded sleeve 22.
[0017] During installation, first insert the bottom of the connecting shaft 4 into the threaded sleeve 22, and then rotate the disc brush body 1 so that the threaded sleeve 22 is threadedly connected to the external thread structure 42 at the upper end of the connecting shaft 4 until the locking hole 41 moves to the locking pin 23 for position locking, thereby realizing quick installation and use of the disc brush body 1.
[0018] A fixed head 5 is provided at the top of the connecting shaft 4, and the fixed head 5 is composed of two groups of fixed blocks 51. A fixing hole 52 is provided in the middle of the two groups of fixed blocks 51. By inserting the transmission shaft 31 of the motor 3 into the fixing hole 52 and locking the two groups of fixed blocks 51 with bolts, the transmission shaft 31 and the fixed head 5 are installed and locked.
[0019] In some examples, a connecting plate 21 is provided in the middle of the bottom end of the connecting base 2. The connecting plate 21 is mounted on the upper end surface of the disc brush body 1 and is fixed by multiple sets of screws.
[0020] In some examples, the bottom of the connecting shaft 4 has a tapered structure, so that when the connecting shaft 4 enters the threaded sleeve 22, the locking pin 23 can be squeezed, causing the locking pin 23 to move toward the inner side of the connecting seat 2 until the locking hole 41 moves to the position of the locking pin 23. At this time, the resistance force is lost, and under the action of the spring 24, the locking pin 23 can be inserted into the locking hole 41 to achieve locked installation of the connecting shaft 4.
[0021] In some examples, a pull ring 26 is installed at the head end of the pull rod 25, and the pull ring 26 is located at the outer end of the connecting seat 2. The setting of the pull ring 26 makes it convenient for the staff to pull the pull rod 25, thereby driving the locking pin 23 to move outward, thereby unlocking the connecting shaft 4.
[0022] The working principle of the present invention is: When the disc brush body 1 needs to be installed, it is only necessary to fix the connecting base 2 on the disc brush body 1 through the connecting disc 21, then insert the connecting shaft 4 into the threaded sleeve 22, and rotate the disc brush body 1 so that the threaded sleeve 22 is threadedly connected with the external thread structure 42. When the connecting shaft 4 is installed, the locking pin 23 on one side of the inner cavity of the threaded sleeve 22 is squeezed until the locking hole 41 moves to the position of the locking pin 23. At this time, under the elastic force of the spring 24, the locking pin 23 is inserted into the locking hole 41, thereby realizing the limited locking installation of the disc brush body 1; On the contrary, when the disc brush body 1 needs to be disassembled, the staff only needs to pull the pull rod 25 outward through the pull ring 26, and the locking pin 23 is pulled out from the locking hole 41 under the drive of the pull rod 25. At this time, the limit lock on the connecting shaft 4 is released, and then the disc brush body 1 only needs to be rotated in the reverse direction to remove the disc brush body 1 from the connecting shaft 4 for replacement.
[0023] The above structure facilitates the installation or disassembly of the disc brush body 1. Furthermore, the provision of the locking assembly can enhance the installation stability of the disc brush body 1, thereby preventing the disc brush body 1 from loosening or falling off during long-term rotation.
[0024] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
