In the invention, the extending end of the driven telescopic cylinder refers to the end, extending away from the rolling brush driving cylinder, of the driven telescopic cylinder, and the extending end of the brush refers to the end, extending away from the rolling brush driving cylinder, of the brush.
Referring to fig. 1 and 2, the present invention provides an automatic retractable rolling brush structure.
An automatic telescopic rolling brush structure comprises a rolling brush driving cylinder 1, a driven telescopic cylinder 2, a rotary bearing 3, a transmission mechanism 4 and a fixed block 5; the rolling brush driving cylinder 1 is sleeved outside the driven telescopic cylinder 2, and the driven telescopic cylinder 2 can be stretched along the axial direction of the rolling brush driving cylinder 1; the periphery of the rotary bearing 3 is fixedly connected with the inner wall of the driven telescopic cylinder 2; the transmission mechanism 4 is used for driving the driven telescopic cylinder 2 to axially reciprocate along the rolling brush driving cylinder 1; the fixed block 5 is arranged on one side of the driven telescopic cylinder 2 and is fixedly connected with one end of the transmission mechanism 4.
Under the drive of external force, the rotary bearing 3 rotates along the transmission mechanism 4, and the displacement occurs on the transmission mechanism 4, so that the driven telescopic cylinder 2 is driven to rotate and displace, and the automatic telescopic function of the rolling brush structure is realized. One end of the transmission mechanism 4 is connected with the fixed block 5, and the rotation of the transmission mechanism 4 can be controlled more conveniently through the fixed block 5. The connecting arm of the rotary bearing 3 is connected with the inner wall of the driven telescopic cylinder 2 close to the opening end, so that the driven telescopic cylinder 2 can be extended outwards as far as possible, and the rolling brush has the maximum flexibility. The actual connecting position of the connecting arm and the inner wall of the driven telescopic cylinder 2 can be adjusted according to actual conditions, so that the connecting arm has the optimal mechanical structure and the optimal maximum extension.
In one embodiment, the extending end of the driven telescopic cylinder 2 is connected with a connecting piece 21 with the radius equal to the outer diameter of the rolling brush driving cylinder 1, and the connecting piece 21 is connected with one end of the rolling brush driving cylinder 1; the outer diameter of the driven telescopic cylinder 2 is matched with the inner diameter of the rolling brush driving cylinder 1.
One end of a roller brush driving cylinder 1 is connected with a connecting piece 21 of a driven telescopic cylinder 2, when the roller brush driving cylinder 1 is driven to rotate through external force, the connecting part of the roller brush driving cylinder 1 and the connecting piece 21 of the driven telescopic cylinder 2 is equivalent to a transmission part, then the driven telescopic cylinder 2 is driven to rotate, the fixed block 5 is kept still, the rotating speeds of the transmission mechanism 4 and the rotating bearing 3 are different, then the rotating bearing 3 can rotate along the transmission mechanism 4, and the driven telescopic cylinder 2 is driven to displace. The external diameter of the driven telescopic cylinder 2 is matched with the internal diameter of the rolling brush driving cylinder 1, so that the driven telescopic cylinder 2 and the rolling brush driving cylinder 1 can be tightly attached, and the stability of the automatic telescopic rolling brush structure is improved.
The essence of the driven telescopic cylinder 2 extending outwards and retracting inwards is that the rotation speed of the driven telescopic cylinder 2 is different from that of the transmission mechanism 4.
In another embodiment, the roller brush driving cylinder 1 and the fixed block 5 are driven to rotate by different driving devices respectively. When the rotating speed of the driven telescopic cylinder 2 is the same as that of the transmission mechanism 4, the driven telescopic cylinder 2 and the transmission mechanism 4 cannot generate relative displacement, the driven telescopic cylinder 2 can be kept in the original position and does not stretch any more, and the width of the rolling brush is kept. Because the driven telescopic cylinder 2 is driven by the rolling brush driving cylinder 1, the stretching out and retracting of the driven telescopic cylinder 2 can be realized by controlling the relative rotating speed and the rotating direction of the rolling brush driving cylinder 1 and the transmission mechanism 4. The rolling brush driving cylinder 1 can switch the rotating direction, the transmission mechanism 4 can only rotate forwards or keep still, and when the rolling brush driving cylinder 1 is controlled to rotate backwards, the driven telescopic cylinder 2 retracts inwards, and the rolling brush is narrowed; when the driving cylinder 1 of the rolling brush is controlled to rotate forwards, the transmission mechanism 4 keeps still, the driven telescopic cylinder 2 extends outwards, and the rolling brush is widened; when the rolling brush driving cylinder 1 is controlled to rotate forwards and the transmission mechanism 4 rotates forwards, and the rotating speed of the rolling brush driving cylinder 1 is controlled to be greater than that of the transmission mechanism 4, the driven telescopic cylinder 2 slowly extends outwards, and the rolling brush is slowly widened; when the rolling brush driving cylinder 1 is controlled to rotate forwards and the transmission mechanism 4 rotates forwards, and the rotating speed of the rolling brush driving cylinder 1 is controlled to be lower than that of the transmission mechanism 4, the driven telescopic cylinder 2 retracts inwards slowly, and the rolling brush narrows slowly; and controlling the rotating speed of the roller brush driving cylinder 1 to be equal to that of the transmission mechanism 4, keeping the position of the driven telescopic cylinder 2 unchanged, and keeping the width of the roller brush unchanged. The control precision of the extension of the rolling brush can be greatly improved by respectively controlling the rotating speeds of the driving cylinder 1 of the rolling brush and the transmission mechanism 4.
The outer wall of the rolling brush driving cylinder is axially provided with a plurality of brush strips 11 and brush grooves 12 which extend along the axial direction of the rolling brush driving cylinder, and the brush strips 11 are clamped on the brush grooves 12 and can slide along the brush grooves 12. In use, the number of the brush bar 11 and the brush groove 12 can be increased according to actual needs. The brush grooves 12 are formed so that the brush strips 11 can be easily detached from the rolling brush driving cylinder 1 for replacement, and the brush strips 11 of different types and materials can be easily replaced by a user according to the cleaning surfaces of different materials. In addition, the position of the brush strip 11 can be conveniently and rapidly adjusted by sliding the brush strip 11, and the rolling range can be adjusted.
In one embodiment, the outer wall of the driven telescopic cylinder 2 is provided with a brush strip 11 capable of ejecting a brush, and when the driven telescopic cylinder 2 extends from the roller brush driving cylinder 1, the brush strip 11 on the extending part of the driven telescopic cylinder 2 can eject the brush.
The brush strip comprises a movable brush strip 111 and a fixed brush strip 112, and the extending end of the brush strip is fixed on the extending end of the driven telescopic cylinder. The movable brush strip 111 can move along with the connecting piece 21 at the extending end of the driven telescopic cylinder 2 to serve as a transmission part between the rolling brush driving cylinder 1 and the driven telescopic cylinder 2, the driven telescopic cylinder 2 is driven to rotate after the rolling brush driving cylinder 1 rotates, the driven telescopic cylinder 2 generates axial displacement due to rotation and reacts on the movable brush strip 111, so that the movable brush strip 111 slides on the brush groove 12, and the width of the rolling brush is changed. When one end of the fixed brush bar 112 is fixed to the extending end of the driven telescopic cylinder 2, the fixed brush bar 112 becomes the movable brush bar 111; on the contrary, when one end of the movable brush bar 111 is not fixed to the extension end of the driven telescopic cylinder 2, it becomes the fixed brush bar 112.
In one embodiment, the base of the brush strip 11 can be made of high-strength metal material or other material with high hardness, the movable brush strip 111 is used as the transmission part between the driving cylinder 1 and the driven telescopic cylinder 2 of the rolling brush, wherein the base of the brush strip 11 is the main stress part, and the metal or hard brush base can prevent the brush strip 11 from easily deforming, thereby enhancing the stability of the rolling brush.
In one embodiment, the base of the brush bar 11 can be installed as a separate module on the roller brush device as a transmission part, and when the brush bar 11 is replaced, the movable brush bar 111 and the telescopic driven cylinder 2 do not need to be removed from the transmission mechanism.
The moving brush bar 111 and the fixed brush bar 112 are spaced apart. The movable brush strips 111 and the fixed brush strips 112 are arranged at intervals, so that the movable brush strips 111 can be uniformly arranged on the rolling brush, after displacement occurs, the movable brush strips 111 are uniformly distributed on the extension part, and the fixed brush strips 112 are also uniformly distributed on the rolling brush driving cylinder 1, so that the stress of the extended roller structure is balanced on the whole.
The periphery wall of the connecting piece 21 is provided with a plurality of clamping blocks 22 for clamping the brush strips. When the driven telescopic cylinder 2 extends outwards, the fixture block 22 moves outwards along with the driven telescopic cylinder 2, and pulls the movable brush strip 111 to move outwards, so that the width of the rolling brush is increased. When the driven telescopic cylinder 2 retracts inwards, the fixture block 22 pushes the movable brush strip 111 to move inwards, and the width of the rolling brush is shortened.
In one embodiment, the two ends of the base of the brush strip 11 are provided with bolt holes, and the latch 212 can be fixedly connected with the movable brush strip 111 by using bolts, or fixedly connected by using a clamping manner, so that the movable brush strip 111 moves along with the latch 22.
The length of the brush strip 11 is not less than that of the driven telescopic cylinder 2. The movable brush strip 111 extends out along with the driven telescopic cylinder 2, the connecting part with the slot position of the brush slot 12 is reduced, and if the length of the brush strip 11 is insufficient, the maximum extension degree of the driven telescopic cylinder 2 is limited. When the driven telescopic cylinder 2 extends to the widest part of the rolling brush, the length of the brush strip 11 is insufficient, and the brush strip 11 can be separated from the slot position of the brush slot 12. In practical use, when the driven telescopic cylinder 2 extends to the widest part of the rolling brush, the brush strip 11 is still partially clamped on the groove position of the brush groove 12 and is used as a transmission part with enough strength to drive the driven telescopic cylinder 2 to rotate. In production, the manufacturing side can adjust the length of the driven telescopic cylinder 2 according to actual needs to be smaller than the rolling brush driving cylinder 1 so as to change the maximum extension degree of the rolling brush, and the rolling brush can have a better mechanical structure in an extension state by adjusting the length of the driven telescopic cylinder 2.
The brush groove 12 is a trapezoidal groove. The trapezoidal groove is wide at the bottom and narrow at the top, and when the lower part of the brush strip 11 is inserted into the groove, the horizontal movement can only occur, but the front and back up and down movement can not occur. Besides the inverted trapezoid structure, the slot structure can also use barbs and other designs.
Referring to fig. 3 and 4, the transmission mechanism 4 includes a front shaft 41, a unidirectional rotation device 42 and a rear shaft 43, one end of the front shaft 41 is connected to the fixed block 5, and the other end of the front shaft 41 is connected to the rear shaft 43 through the unidirectional rotation device 42. When the rolling brush driving cylinder 1 rotates forwards to drive the driven telescopic cylinder 2 to rotate, the rotary bearing 3 connected with the driven telescopic cylinder 2 rotates on the transmission mechanism 4 and is screwed out outwards along the threads, when the rotary bearing 3 leaves the front shaft 41 and passes through the one-way rotating device 42, a part of the rotary bearing 3 reaches the rear shaft 43, the rear shaft 43 does not rotate along with the front shaft 41 under the action of the one-way rotating device 42 and can only rotate forwards, when the rotary bearing 3 reaches the rear shaft 43, the rear shaft 43 can rotate forwards along with the rotation of the rotary bearing 3, because the rotary speeds of the rotary bearing 3 and the rear shaft 43 are the same, the rotary bearing 3 can only idle in situ and cannot rotate outwards, and the rolling brush at the moment reaches the maximum width. The unidirectional rotating device 42 can prevent the driven telescopic cylinder 2 from excessively extending in a rotating manner, so that the rolling brush driving cylinder 1 is separated from the driven telescopic cylinder 2. Meanwhile, when the rolling brush needs to be adjusted to the maximum width, only the driving cylinder 1 of the rolling brush needs to be rotated, and the problem that the driven telescopic cylinder 2 is separated due to excessive extension does not need to be worried about.
Referring to fig. 5, in an embodiment, the unidirectional rotating device 42 is a ratchet mechanism 44, and a length of the connecting shaft 441 of the ratchet mechanism 44 is smaller than a length of the transmission mechanism through hole of the rotating bearing 3. When the rotary bearing 3 reaches the rear shaft 43 from the front shaft 41 through the ratchet mechanism 44 in the extension stage or the rotary bearing 3 reaches the front shaft 41 from the rear shaft 43 through the ratchet mechanism 44 in the retraction stage, if the length of the transmission mechanism through hole 41 of the rotary bearing 3 is smaller than the length of the connecting shaft 441 of the ratchet mechanism 44, when the rotary bearing 3 rotates to the connection position of the front shaft 41 and the connecting shaft 441, the rotary bearing 3 leaves the front shaft 41 and enters the connecting shaft 441 of the ratchet mechanism 44, because the length of the transmission mechanism through hole of the rotary bearing 3 is insufficient, after leaving the front shaft 41, the thread of the rear shaft 43 cannot be connected with the rotary bearing 3, and the connecting shaft 441 of the ratchet mechanism 44 has no thread, the rotary bearing 3 can only idle on the connecting shaft 441 of the ratchet mechanism 44, because the radius of the connecting shaft 441 of the ratchet mechanism 44 is smaller than the radius of the front shaft 41, so as to cause the displacement path of the rotary bearing 3 to be deviated, is caught on the connecting shaft 441 of the ratchet mechanism 44. When the roller brush driving cylinder 1 is driven to rotate backward, the rotary bearing 3 is locked on the connecting shaft 441 of the ratchet mechanism 44 to idle, and cannot be connected with the front shaft 41 to rotate backward. And when the length of the connecting shaft 441 of the ratchet mechanism 44 is smaller than the length of the through hole of the transmission mechanism 3 of the rotary bearing 3, the rotary bearing 3 can stride over the connecting shaft 441 of the ratchet mechanism 44 to realize the position switching between the front shaft 41 and the rear shaft 43. The connecting shaft 441 of the ratchet mechanism 44 may be completely inserted into the front shaft 41 and hidden. The length of the rear axle 43 need not be too long and can be less than the length of the drive mechanism through hole of the rotary bearing 3, but not too short, or it can be under-stressed.
Referring to fig. 6, the ratchet mechanism 44 is fixed on the front axle 41 and rotates with the front axle 41, and the ratchet mechanism 44 includes a connecting shaft 441, a ratchet 442 and a pawl 443; the connecting shaft 441 of the ratchet mechanism 44 is connected with the front shaft 41; the end of the ratchet wheel 442 of the ratchet mechanism 44 is connected to the rear shaft 43, when the rear shaft 43 rotates forward with the rotary bearing 3, the pawl 443 can slide on the back of the teeth of the ratchet wheel 442, when the rotary bearing 3 rotates backward, the pawl 443 is inserted into the teeth of the ratchet wheel 442 to prevent the rear shaft 43 from rotating backward, and at this time, the rotation speed of the rotary bearing 3 is greater than that of the rear shaft 43, and the rotary bearing 3 can rotate backward.
It should be understood that equivalents and modifications of the technical solution and inventive concept thereof may occur to those skilled in the art, and all such modifications and alterations should fall within the scope of the appended claims.
