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 FIGS. 1-2, FIG. 1 is a longitudinal sectional view of the present invention; fig. 2 is a partially enlarged view of a portion a in fig. 1.
The invention provides an easy-to-mount and easy-to-dismount sanitation cleaning disc brush assembly, 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 a driving motor output shaft for driving the disc brush 1 to rotate 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, wherein the brush hair unit 12 comprises an installation block and brush hair, one end of the brush hair is arranged on the installation block, and the other end of the brush hair extends downwards to the lower part of the brush disc 1. The replacement of the brush bristles is actually to replace the brush bristle unit 12, the worn brush bristles are taken down from the disc brush body 11 together with the mounting block during replacement, and the new brush bristle unit 12 is inserted into the disc brush body 11. The bristles are arranged obliquely relative to the horizontal plane. 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, the lower end of the connecting shaft 2 is mounted in the mounting hole 111, and the mounting hole 111 is in a disc-shaped structure and is matched with the shape of the connecting shaft 2. The upper end of connecting axle 2 is equipped with the protruding 21 of location of protrusion its surface, and dish brush body 11 sets up the positioning groove 112 of holding the protruding 21 of location, and as long as positioning protrusion 21 aims at positioning groove 112 and inserts into when installation dismantlement like this, subsequent expanding device 3 that contracts just can accurately aim at draw-in groove 113, has seted up at least one draw-in groove 113 on the inside wall of mounting hole 111, and in this embodiment, the number of draw-in groove 113 is the even number, and two liang be a set of, and two draw-in grooves 113 of every group use the axis of connecting axle 2 as the symmetry setting. Specifically, the number of the card slots 113 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 113 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 or other structures. In this embodiment, the expansion and contraction device 3 is realized by using gravity to realize natural contraction and by using the subsequent anti-falling mechanism 6.
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. 2, in the present embodiment, the present invention further includes a guiding device 5, the guiding device 5 includes a guiding groove 51 extending along the vertical direction and a sliding block 52 slidably disposed in the guiding groove 51, the guiding groove 51 is opened on the connecting shaft 2, and the sliding block 52 is mounted on the inner side wall of the shaft sleeve 31. The guiding device 5 guides the expanding action of the expanding and contracting device 3, so that when the first connecting rod 32 and the second connecting rod 33 rotate relatively, the two are always in a vertical plane without deviation.
As shown in fig. 2, in the present embodiment, the anti-dropping mechanism 6 further includes a first anti-dropping hanger 61 extending upward from the top of the driving device 4, a second anti-dropping hanger 62 extending downward from the bottom of the shaft sleeve 31, and the first anti-dropping hanger 61 and the second anti-dropping hanger 62 cooperate to form the anti-dropping mechanism 6. The cross-sectional profiles of the first anti-falling hanging piece 61 and the second anti-falling hanging piece 62 are both L-shaped, and the top of the first anti-falling hanging piece 61 is located above the top of the second anti-falling hanging piece 62. The anti-drop mechanism 6 prevents the shaft sleeve 31 and the driving device 4 from being separated from each other, and indirectly achieves the effect of promoting the contraction and expansion device 3 to contract and 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 113.
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.
