Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1, fig. 1 is a longitudinal sectional view of the present invention.
The invention provides an easy-to-mount and easy-to-dismount structure of a sanitation cleaning disc brush, which comprises a disc brush 1 and a connecting shaft 2 detachably connected with the disc brush 1, wherein the top of the connecting shaft 2 is provided with a butt joint hole, and the butt joint of the connecting shaft 2 and an output shaft of a driving motor for driving the rotation of the disc brush 1 can be realized through the butt joint hole. The disc brush 1 comprises a disc brush body 11 and a brush hair unit 12 arranged on the disc brush body 11, the brush hair unit 12 comprises an installation block 121 and brush hair 122, the brush hair 122 is replaced by the brush hair unit 12, the brush hair 122 which is lost is taken down from the disc brush body 11 together with the installation block 121 during replacement, and the new brush hair unit 12 is inserted into the disc brush body 11. Bristles 122 are mounted at one end to the mounting block 121 and extend downwardly below the brush plate 1 at the other end. The bristles 122 are disposed at an angle to the horizontal. This can enlarge the cleaning area of the disc brush 1.
As shown in fig. 1, a mounting hole 111 is formed in the middle of the disc brush body 11, and the shape of the mounting hole 111 is adapted to the shape of the connecting shaft 2 and has a disc-shaped structure. The lower end of the connecting shaft 2 is installed in the installation hole 111, and at least one clamping groove 112 is formed in the inner side wall of the installation hole 111, in this embodiment, the number of the clamping grooves 112 is even, each two clamping grooves are in one group, and the two clamping grooves 112 in each group are symmetrically arranged by taking the axis of the connecting shaft 2 as a symmetry axis. Specifically, the number of card slots 112 is 2. So that the disc brush 1 is fixed with the connecting shaft 2 more stably.
As shown in fig. 1, the connecting shaft 2 is provided with an expansion and contraction device 3 capable of expanding towards the periphery of the connecting shaft 2 to be clamped with the clamping groove 112 and a driving device 4 for driving the expansion and contraction device 3 to expand, and the lower end of the expansion and contraction device 3 is abutted against the driving device 4. The expansion action of the expansion and contraction device 3 is driven by the driving device 4, and the contraction action of the expansion and contraction device 3 is realized by taking external natural factors such as gravity as power. In this embodiment, the expansion and contraction device 3 utilizes gravity to realize natural contraction.
As shown in fig. 1, the expansion and contraction device 3 includes a shaft sleeve 31 disposed on the periphery of the connecting shaft 2, and a first connecting rod 32 and a second connecting rod 33 rotatably connected to each other, one end of the first connecting rod 32 is rotatably connected to the connecting shaft 2, the other end of the first connecting rod 32 is rotatably connected to one end of the second connecting rod 33, the other end of the second connecting rod 33 is rotatably connected to the shaft sleeve 31, and the shaft sleeve 31 abuts against the driving device 4. The expansion and contraction device 3 has two states, i.e., an expanded state and a contracted state. In any case, the first link 32 and the second link 33 are always in a bent state at the connection position between the two regardless of the expanded state or the contracted state, but in the contracted state, the included angle between the first link 32 and the second link 33 is an obtuse angle and is relatively large, and in the expanded state, the included angle between the first link 32 and the second link 33 is an acute angle and is relatively small. The shaft sleeve 31 has at least two functions in this embodiment, one is to connect the lower ends of all the second connecting rods 33 (the number of the expansion devices 3 is more than one, and there are two in this embodiment), so as to ensure that the lower ends of the second connecting rods 33 are always located on the shaft sleeve 31, and the other is to increase the gravity of the first connecting rods 32 and the second connecting rods 33, so as to ensure that the two can be automatically reset.
As shown in fig. 1, the driving device 4 is sleeved on the periphery of the connecting shaft 2 and moves up and down along the axial direction of the connecting shaft 2. Drive arrangement 4 also overlaps the axle sleeve in connecting axle 2 periphery for the activity, and drive arrangement 4 can be with 2 spiro couplings of connecting axle or joint, in this embodiment, is equipped with the internal thread on drive arrangement 4's the inside wall, is equipped with the external screw thread that links to each other with the internal thread on the periphery wall of connecting axle 2, and drive arrangement 4 links to each other through screw-thread fit with connecting axle 2. Thus, the driving device 4 is rotated to move the driving device 4 up and down along the axial direction of the connecting shaft 2, the driving device 4 will cause the expansion and contraction device 3 to expand when moving up along the axial direction of the connecting shaft 2, the first connecting rod 32 and the second connecting rod 33 are bent at the joint of the two to form a V-shaped structure, and the tip of the V-shaped structure extends into the clamping groove 112 to be clamped with the clamping groove 112.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
