Description

Technical Field

[0001] The present invention belongs to the field of transmission parts, and in particular relates to a single-wheel dual-control gear structure. Background Art

[0002] Traditional household sewage lifts have limited effect on pulverizing sewage and are unable to handle large solid foreign matter such as fiber and gravel. In addition, their pulverizing blades are easily stuck by foreign matter and stop the machine. If the pulverizing blades encounter hard foreign matter, such as metal, there is a hidden danger of damaging the sewage lift. In order to facilitate the diversion of sewage containing metal and non-metal, two guide plates are used for diversion. Currently, most of the control systems on the market use two motors to drive the two guide plates separately, which easily increases the drive box of the sewage lift and reduces the cavity for storing sewage. Summary of the Invention

[0003] In view of the above shortcomings, the technical problem to be solved by the present invention is to provide a single-wheel dual-control gear knot, which uses a single drive motor to drive two driven gears in a time-sharing manner, reducing the volume of the cavity used to install the drive components, and making the structure of the sewage treatment device more reasonable.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A single-wheel dual-control gear structure includes a driving wheel, a driven wheel group and a driving mounting plate. The driving wheel and the driven wheel group are both rotatably mounted on the driving mounting plate. A rebound component is installed between the driven wheel group and the driving mounting plate to drive the driven wheel group to rebound.

[0006] Furthermore, a driven wheel rebound hole is dug on the driven wheel assembly, and correspondingly, a mounting plate rebound hole is also dug on the driving mounting plate, and both ends of the rebound component are respectively connected to the driven wheel rebound hole and the mounting plate rebound hole.

[0007] Furthermore, the driven wheel assembly includes a first driven wheel and a second driven wheel, both of which are provided with driven wheel rebound holes, and the driving wheel is intermittently connected to the first driven wheel and the second driven wheel respectively.

[0008] Furthermore, the driving wheel is fixedly connected with square teeth, and the first driven wheel and the second driven wheel have the same structure, both including a toothed disc and rotating teeth, and a tooth groove is dug on the side wall of the toothed disc, and the rotating teeth are rotatably installed in the tooth groove, and the square teeth are intermittently connected to the rotating teeth.

[0009] Furthermore, a rotating gear installation groove is dug in the tooth groove, and the rotating gear is rotatably installed in the rotating gear installation groove.

[0010] Furthermore, the gear mounting groove includes a gear clamping portion, a gear mounting portion and a gear receiving portion. The gear is rotatably mounted in the gear mounting portion. The gear clamping portion is intermittently limitedly connected to the gear, and the gear receiving portion is intermittently received connected to the gear.

[0011] Furthermore, the first driven wheel and the second driven gear are symmetrically arranged.

[0012] Furthermore, a tooth portion and a light portion are fixedly connected to the side wall of the driving wheel, and the tooth portion is intermittently connected to the first driven wheel and the second driven wheel.

[0013] Furthermore, the first driven wheel and the second driven wheel are both gears.

[0014] Furthermore, the first driven wheel and the second driven wheel are evenly distributed with clamping columns on their circumferences, and the spacing between adjacent clamping columns is adapted to the width of the teeth of the gear portion.

[0015] The beneficial effect of the present invention is that after the driving wheel drives the driven wheel group, the driven wheel group 2 is reset to the initial position through the rebound component, thereby resetting the baffle connected to the driven wheel group, and the invalid motor drive can be directly reset, thereby improving the reset efficiency.

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Example 1

[0023] A single-wheel dual-control gear structure includes a driving wheel 1, a driven wheel group 2 and a driving mounting plate 3. The driving wheel 1 and the driven wheel group 2 are both rotatably mounted on the driving mounting plate 3. A rebound component 4 is installed between the driven wheel group 2 and the driving mounting plate 3. After the driving wheel 1 drives the driven wheel group 2, the rebound component 4 resets the driven wheel group 2 to its initial position, thereby resetting the baffle 21 connected to the driven wheel group 2. Invalid motor drive can be directly reset, thereby improving reset efficiency.

[0024] A driven wheel rebound hole 5 is dug on the driven wheel group 2, and correspondingly, a mounting plate rebound hole 6 is also dug on the driving mounting plate 3. The two ends of the rebound component 4 are respectively connected to the driven wheel rebound hole 5 and the mounting plate rebound hole 6, so that the initial position of the driven wheel group 2 relative to the driving mounting plate 3 remains unchanged. Preferably, the rebound component 4 is a torsion spring.

[0025] The driven wheel group 2 includes a first driven wheel 7 and a second driven wheel 8. The first driven wheel 7 and the second driven wheel 8 are both provided with a driven wheel rebound hole 5. The driving wheel 1 is intermittently connected to the first driven wheel 7 and the second driven wheel 8 respectively, that is, the driving wheel 1 can be connected to the first driven wheel 7 or the second driven wheel 8 according to the driving requirements. The two driven wheels are driven in a time-sharing manner by one driving wheel 1, which reduces the number of driving components, thereby reducing the volume of the cavity for installing the driving components, making the structure of the sewage lift more reasonable.

[0026] A square tooth 9 is fixedly connected to the driving wheel 1. The first driven wheel 7 and the second driven wheel 8 have the same structure, both including a gear disc 10 and a rotating tooth 11. A tooth groove 12 is dug on the side wall of the gear disc 10, and the rotating tooth 11 is rotatably installed in the tooth groove 12. The square tooth 9 is intermittently connected to the rotating tooth 11, that is, the square tooth 9 is connected to the square teeth of the first driven wheel 7 or the square teeth of the second driven wheel 8 according to the driving requirements.

[0027] A rotating gear mounting groove 13 is dug inside the tooth groove 12, and the rotating gear 11 is rotatably mounted in the rotating gear mounting groove 13. Through the arrangement of the rotating gear relative to the rotating rod, when the square tooth is engaged with the rotating gear in the reverse direction, the driven wheel is driven to rotate, and when the square tooth is engaged with the rotating gear in the forward direction, the driven wheel is not driven to rotate.

[0028] The gear mounting groove 13 includes a gear clamping portion 14, a gear mounting portion 15 and a gear receiving portion 16. The gear 11 is rotatably mounted in the gear mounting portion 15 to facilitate the rotation of the gear 11 relative to the sprocket 10. The gear clamping portion 14 is intermittently limitedly connected to the gear 11. When the gear 11 is clamped with the gear clamping portion 14, the gear 11 cannot rotate relative to the sprocket, thereby enabling the driving wheel 1 to drive the driven wheel. The gear receiving portion 16 is intermittently received and connected to the gear 11. The gear receiving portion 16 is used to receive the gear 11 to prevent the gear 11 from interfering with the driving wheel 1.

[0029] In some preferred embodiments, an elastic head 17 is provided in the gear storage portion 16, and the elastic head is used to push out the gear 11. When the driving wheel rotates in the reverse direction, the elastic head 17 pushes out the gear 11, and the gear 11 is engaged with the gear engaging portion 14, so that the driving wheel 1 drives the driven wheel to rotate. When the driving wheel rotates in the reverse direction, the driving wheel 1 squeezes the gear 11, the elastic head contracts, and the driving wheel cannot drive the driven wheel.

[0030] The first driven wheel 7 and the second driven wheel 8 are symmetrically arranged so that when the first driven wheel 7 is connected to the driving wheel 1 , the second driven wheel 8 is not connected to the driving wheel 1 ; otherwise, the second driven wheel 8 is connected to the driving wheel 1 .

[0031] Example 2

[0032] A toothed portion 18 and a light portion 19 are fixedly connected to the side wall of the driving wheel 1. The toothed portion 18 is intermittently connected to the first driven wheel 7 and the second driven wheel 8. That is, the driving wheel 1 is an incomplete gear, and the first driven wheel 7 and the second driven wheel 8 are both gears. The light portion 19 cannot drive the first driven wheel 7 and the second driven wheel 8 to be connected, and the toothed portion 18 is intermittently meshed with the first driven wheel 7 and the second driven wheel 8.

[0033] The rest of the structure is consistent with that of the first embodiment.

[0034] Example 3

[0035] The driving wheel 1 is an incomplete gear, and the first driven wheel 7 and the second driven wheel 8 are evenly distributed with clamping columns 20 on their circumferences. The spacing between adjacent clamping columns 20 is adapted to the width of the teeth of the incomplete gear, facilitating the connection between the teeth 18 and the clamping columns 20.

[0036] The rest of the structure is consistent with that of the first embodiment.
