Referring to fig. 2 to 5, the connection assembly includes a connection member 51, an elastic member 53, and a stopper 52.

The bottom of the connecting piece 51 is open, the connecting piece 51 is sleeved on the output shaft 32 of the clutch in a sliding way, and the connecting piece 51 is at least partially positioned in the accommodating groove of the connecting body 42. In the present embodiment, the connecting body 42 is vertically slidable with respect to the connecting member 51. Also, in a natural state, the bottom of the connection body 42 is flush with the bottom of the connection piece 51.

The connection member 51 includes a body portion 421 and a first protrusion 512 protruding outward from an outer periphery of the body portion 421.

Specifically, the body 421 has a cylindrical shape with an opening at the bottom, and is slidably disposed on the output shaft 32. The outer diameter of the body 421 is smaller than the inner diameter of the portion of the boss 422 where the vertical surface 4221 is located.

When in a natural state, the body 421 is at least partially located in the accommodating groove, and the upper portion thereof is at least partially located in the through hole 411, and the bottom of the body 421 is flush with the bottom of the connector 42.

And, the axis of the body portion 421 extends vertically, and the axis of the body portion 421 coincides with the axis of the output shaft 32.

In the present embodiment, the dimension of the body 421 in the vertical direction is greater than the dimension of the through hole 411 and the receiving groove in the vertical direction, that is, when the bottom of the body 421 is level with the bottom of the connector 42, the upper portion of the body 421 passes through the through hole 411 and protrudes upward beyond the top of the tray 41.

At least one limiting hole is formed in the lower portion of the body 421, the at least one limiting hole and the at least one limiting groove 321 are arranged in a one-to-one correspondence mode, and the axis of the limiting hole extends horizontally. At this time, the opening direction of the limiting groove 321 faces the limiting hole and is communicated with the limiting hole in a one-to-one correspondence manner.

In this embodiment, the number of the limiting holes may be two, and the two limiting holes are respectively arranged at two opposite ends of the body 421 along the radial direction and are correspondingly communicated with the two limiting grooves 321 one by one. In other embodiments, the number of the limiting holes may be three, four or other numbers, where the plurality of the limiting holes are uniformly arranged along the circumferential direction of the body 421, and the number of the limiting holes needs to correspond to the number of the limiting grooves 321.

The first protrusion 512 is located at an upper portion of the body 421, and a top of the first protrusion 512 is flush with a top of the body 421. When the connecting member 51 is located in the accommodating groove of the connecting body 42, an accommodating space is formed by the first protrusion 512, the outer sidewall of the body 421, the boss 422, and the inner sidewall of the body 511.

Specifically, the first projection 512 has a radial dimension smaller than the inner diameter dimension of the through hole 411 to facilitate sliding of the connection member 51 relative to the output shaft 32 of the clutch. And, the external diameter of the first protrusion 512 is greater than the internal diameter of the portion of the vertical surface 4221 of the boss 422, so that the first protrusion 512 and the boss 422 cooperate with each other to limit the relative sliding displacement range between the connecting body 42 and the connecting member 51, and at the same time, the connecting member 51 can be prevented from falling out of the accommodating groove of the connecting body 42.

In this embodiment, the connection member 51 further includes a second protrusion 513 protruding from an outer sidewall of the body 421, the second protrusion 513 is located at a lower portion of the body 421, and a bottom of the second protrusion 513 is flush with a bottom of the body 421. At this time, the limiting hole is located above the second projection 513.

The outer side of the second projection 513 is gradually inclined outwardly from top to bottom at least partially, and the inclination angle coincides with the inclination angle of the inclined surface 4222 of the boss 422. When the connecting member 51 is positioned in the accommodating groove of the connecting body 42 and the bottom of the connecting body 42 is level, the outer side of the second protrusion 513 is abutted against the inclined surface 4222 of the boss 422, so that the outer side can be used for abutting against the inclined surface 4222; moreover, the second protrusion 513 cooperates with the first protrusion 512 to limit the displacement range of the boss 422 in the vertical direction, and limit the displacement range of the connector 42 sliding in the vertical direction relative to the connector 51; meanwhile, the connecting piece 51 is limited on the connecting body 42 through the first bulge 512 and the second bulge 513 to form a whole.

In this embodiment, the outer sidewall of the second protrusion 513 includes an inclined section 5131 and a vertical section 5132 sequentially arranged from top to bottom. The inclined section 5131 is gradually inclined outwards from top to bottom, and the inclined angle of the inclined section 5131 is consistent with the inclined angle of the inclined face 4222, so that the inclined section 5131 can be used for abutting against the inclined face 4222. The vertical segment 5132 is spaced from the inclined face 4222. In other embodiments, the outer sidewall of second projection 513 may include only sloped section 5131.

The limiting piece 52 is located on the periphery of the connecting piece 51, and two opposite sides of the limiting piece 52 are respectively abutted against the output shaft 32 and the connecting body 42. When the connector 42 slides vertically downwards relative to the connector 51, the limiting piece 52 can be close to the output shaft 32 and abut against the periphery of the output shaft 32, so that the locking of the connector 42 and the output shaft 32 is realized, and the quick assembly of the impeller disc 4 is realized; when the connector 42 slides vertically upwards relative to the connector 51, the limiting piece 52 can be far away from the output shaft 32, so that unlocking of the connector 42 and the output shaft 32 is realized, and quick disassembly of the impeller disc 4 is realized.

The limiting piece 52 is correspondingly arranged in the limiting hole, and the limiting piece 52 can be clamped in the limiting groove 321 or withdrawn from the limiting groove 321. Specifically, when the connector 42 slides vertically downward relative to the connector 51, during the process of sliding the connector 42 downward, the inclined surface 4222 of the boss 422 is firstly abutted against the limiting member 52, because the inclined surface 4222 of the boss 422 is inclined outwards from top to bottom, as the connector 42 slides continuously, the largest dimension between the inclined surface 4222 of the boss 422 and the limiting groove 321 along the horizontal direction is continuously reduced, at this time, the inclined surface 4222 can play a guiding role, continuously squeeze the limiting member 52 to move the limiting member 52 along the axial direction of the limiting hole and clamp the limiting member in the limiting groove 321, then the vertical surface 4221 of the boss 422 is abutted against the outer side of the limiting member 52, so that the limiting member 52 is abutted against the side wall of the limiting groove 321, and the limiting member 52 is prevented from moving along the axial direction of the limiting hole, so as to lock the connector 42 and the output shaft 32, and realize the fast assembly of the roulette 4. When the connector 42 and the output shaft 32 are in the locked state, the line connecting the abutment point between the vertical surface 4221 of the boss 422 and the stopper 52 and the center of the stopper 52 extends horizontally, and the abutment point is located at the middle of the vertical surface 4221 in the vertical direction.

When the connecting body 42 vertically slides upwards relative to the connecting piece 51 until the inclined surface 4222 of the boss 422 abuts against the limiting piece 52, as the well receiving cap continuously slides upwards, the largest dimension between the inclined surface 4222 of the boss 422 and the limiting groove 321 along the horizontal direction is continuously increased, and the limiting piece 52 can move along the axial direction of the limiting hole to be far away from the output shaft 32 due to no blocking on the outer side of the limiting piece 52, and then exits from the limiting groove 321, so that the unlocking of the connecting body 42 and the output shaft 32 is realized, and the quick disassembly of the impeller disc 4 is realized.

In this embodiment, the stopper 52 has a spherical shape. The outer diameter D of the stopper 52 is equal to the vertical dimension H of the vertical surface 4221 of the boss 422, and the vertical dimension H of the vertical surface 4221 and the outer diameter D of the stopper 52 satisfy the following relationship: h > D/2. And, the maximum dimension of the limiting groove 321 along the horizontal direction is L, and the maximum dimension L of the limiting groove 321 along the horizontal direction and the outer diameter D of the limiting piece 52 satisfy the following relationship: l < D/2.

In this embodiment, the limiting member 52 may be a steel ball.

In this embodiment, the number of the limiting members 52 may be two, and the two limiting members 52 are disposed in the two limiting holes in a one-to-one correspondence. In other embodiments, the number of the limiting members 52 may be three, four or other numbers, and the number of the limiting members 52 may be adapted to be consistent with the number of the limiting holes.

The elastic member 53 is sleeved on the outer periphery of the connecting member 51, and the upper and lower ends of the elastic member 53 are respectively abutted against the connecting member 51 and the connecting body 42.

Specifically, the elastic member 53 is located in the accommodating space, and the upper and lower ends of the elastic member 53 are respectively abutted against the bottom of the first protrusion 512 and the top of the boss 422, that is, the upper end of the elastic member 53 is abutted against the bottom of the first protrusion 512, and the lower end of the elastic member 53 is abutted against the top of the boss 422.

Moreover, the dimension of the elastic member 53 in the vertical direction is greater than the dimension of the accommodating space in the vertical direction in the natural state, that is, when the elastic member 53 is located in the accommodating space, it is always in a compressed state and has elastic potential energy, because the upper and lower ends of the elastic member 53 are respectively abutted against the first protrusion 512 and the boss 422, at this time, the elastic member 53 is about to restore to the natural state, and the first protrusion 512 is respectively pushed up, the boss 422 is pressed down, so as to prevent the connector 42 from sliding up relative to the connector 51, resulting in the stopper 52 exiting the limiting groove 321, and at the same time, the boss 422 is pressed down against the second protrusion 513, so as to prevent the connector 51 from sliding up, so that the connector 42 and the output shaft 32 of the clutch are in a locked state, and further the roulette 4 can be tightly mounted on the output shaft 32.

In this embodiment, the elastic member 53 may employ a spring.

Further, in the present embodiment, a washer is further provided between the connecting member 51 and the output shaft 32 to increase the friction between the connecting member 51 and the output shaft 32, while preventing the connecting member 51 from rotating in the circumferential direction with respect to the output shaft 32.

Since the connecting piece 51 is limited on the connecting body 42 through the first protrusion 512 and the second protrusion 513, the limiting piece 52 is limited in the limiting hole, and the elastic piece 53 is limited in the accommodating space formed by the first protrusion 512, the body 421, the boss 422 and the body 511, the connecting piece 51, the limiting piece 52, the elastic piece 53, the connecting body 42 and the disc 41 form a device of the wave wheel disc 4.

When it is desired to disassemble the pulley disc 4, it is actually the pulley disc 4 device that is disengaged from the clutch output shaft 32. Because the connecting body 42 and the tray body 41 are integrally formed, at this time, the connecting body 42 can slide vertically upwards along with the tray body 41 by grabbing the convex ribs protruding on the tray body 41, and in the process, the elastic piece 53 continues to compress so that the elastic potential energy of the elastic piece is increased; when the connector 42 slides up to the inclined surface 4222 of the boss 422 and abuts against the limiting member 52, as the well receiving cap slides up continuously, the largest dimension between the inclined surface 4222 of the boss 422 and the limiting groove 321 along the horizontal direction increases continuously, and the limiting member 52 can move along the axial direction of the limiting hole to be far away from the output shaft 32 due to no blocking on the outer side of the limiting member 52, and then exits from the limiting groove 321, so that unlocking of the connector 42 and the output shaft 32 is realized. At this time, the elastic member 53 is in the maximum compression state, the protruding rib is continuously lifted upwards, the connecting body 42 and the connecting member 51 are kept in a relatively static state, and the connecting member 51 slides upwards relative to the output shaft 32 of the clutch until the connecting member 51 is separated from the output shaft 32, so that the impeller disc 4 is separated from the output shaft 32, and the impeller disc 4 is detached so as to facilitate cleaning and maintenance.

Since the connecting body 42 is flush with the bottom of the connecting member 51 in the natural state, the vertical surface 4221 of the boss 422 abuts against the stopper 52. When the impeller disc 4 after cleaning and maintenance is required to be mounted on the output shaft 32, the connecting body 42 can slide vertically upwards along with the disc body 41 by lifting the protruding ribs, and in the process, the elastic piece 53 continues to compress so that the elastic potential energy of the elastic piece is increased; when the inclined surface 4222 of the boss 422 slides up the connector 42 and abuts against the stopper 52, as the well receiving cap slides up continuously, the largest dimension between the inclined surface 4222 of the boss 422 and the stopper 321 in the horizontal direction increases continuously, and the stopper 52 can move along the axial direction of the stopper hole to be far away from the output shaft 32 due to no blocking at the outer side of the stopper, and then exits the stopper 321. And then the impeller disc 4 device is moved to the position of the output shaft 32, the opening of the connecting piece 51 is opposite to the output shaft 32, and when the impeller disc 4 device is moved downwards vertically until the top in the connecting piece 51 is abutted against the top of the output shaft 32, the external force applied to the convex rib is released, at the moment, the connecting piece 51 and the output shaft 32 are relatively static, and the connecting body 42 slides downwards relative to the connecting piece 51 with the disc body 41 under the reaction force of the elastic piece 53. In this process, the inclined surface 4222 of the boss 422 is firstly abutted against the limiting member 52, and as the inclined surface 4222 of the boss 422 is inclined outwards from top to bottom, the largest dimension between the inclined surface 4222 of the boss 422 and the limiting groove 321 along the horizontal direction is continuously reduced along with the continuous sliding down of the connecting body 42, the limiting member 52 is moved along the axial direction of the limiting hole under the guiding action of the inclined surface 4222 and is clamped in the limiting groove 321, and then the vertical surface 4221 of the boss 422 is abutted against the outer side of the limiting member 52, so that the limiting member 52 is abutted against the side wall of the limiting groove 321, and the limiting member 52 is prevented from moving along the axial direction of the limiting hole. Further, since the elastic member 53 is always in a compressed state when in the accommodating space, the elastic member 53 is about to restore to a natural state, and the first protrusion 512 is pushed up and the boss 422 is pressed down, so as to prevent the connector 42 from sliding upward relative to the connector 51, and the limiting member 52 is prevented from exiting the limiting groove 321, and simultaneously, the boss 422 is pressed down against the second protrusion 513, so as to prevent the connector 51 from sliding upward, so that the connector 42 and the output shaft 32 of the clutch are in a locked state, and further, the pulley disc 4 can be tightly mounted on the output shaft 32.

According to the technical scheme, the utility model has at least the following advantages and positive effects:

the connecting body can slide vertically relative to the connecting piece, so that the limiting piece can be close to or far away from the output shaft, and further quick assembly and quick disassembly of the impeller disc and the output shaft are realized.

Further, the connecting piece is limited on the connecting body through the first bulge and the second bulge, so that the connecting piece can be prevented from falling off from the accommodating groove of the connecting body, and meanwhile, the displacement range of the boss along the vertical direction can be limited, and the displacement range of the connecting piece relative to the connecting piece along the vertical sliding direction is limited.

Further, since the elastic member is always in a compressed state when in the accommodating space, the elastic member is about to restore to a natural state, and the first protrusion is pushed up and the boss is pressed down respectively, so that the connector is prevented from sliding upwards relative to the connector, the limiting member is prevented from exiting the limiting groove, and meanwhile, the boss is pressed down to the second protrusion, so that the connector is prevented from sliding upwards, the connector and the output shaft of the clutch are in a locking state, and the impeller disc can be tightly mounted on the output shaft.
