Description

Technical Field

[0001] The present invention relates to the field of vacuum pumps, and particularly to a piston-type vacuum pump device dedicated to breast pumps. Background Art

[0002] A piston-type vacuum pump, also known as a reciprocating vacuum pump, is a common type of vacuum pump. During the milking process of cattle and sheep, in order to improve the milking efficiency, most milking machines are used in combination with piston-type vacuum pumps for automated milking operations. During the milking process, the piston-type vacuum pump uses the reciprocating movement of the piston inside to generate suction force, and sucks out the milk of cattle and sheep through the milking machine.

[0003] However, in the actual operation process, since most piston-type vacuum pumps are placed on the ground for use, it is very easy for cattle and sheep to kick the piston-type vacuum pump when entering and leaving the cattle and sheep sheds. On the one hand, this process is likely to cause harm to cattle and sheep, and on the other hand, frequent bumping of the piston-type vacuum pump is likely to accelerate its damage, resulting in a low service life. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the background art and propose a piston-type vacuum pump device dedicated to breast pumps.

[0005] To achieve the above purpose, the technical solution adopted by the present invention is: a piston-type vacuum pump device dedicated to breast pumps, including a pump body. A pump base is fitted to the lower end of the pump body. A suspension pressure member is provided between the pump base and the pump body. A suspension rod is connected to the middle of the suspension pressure member. A suspension sleeve is slidably installed on the outer surface of the suspension rod. A first card seat is obliquely provided at the rear of the upper end of the suspension sleeve. A second card seat is slidably installed on the side of the first card seat. The second card seat is vertically arranged. The opening direction of the second card seat is opposite to the position where the first card seat is located. The opening of the first card seat faces backward. A claw is rotatably installed at the front end of the first card seat. An inclined top plate extends from the front end of the second card seat. One end of the claw abuts against the inclined top plate. The suspension sleeve is connected to the claw. A rotation adjustment member is provided between the suspension sleeve and the suspension rod.

[0006] Preferably, a top post extends from the side of the first card seat. A chute is provided at the end of the top post. A prism cap is slidably installed inside the chute. A connecting post extends from the middle of the side of the prism cap. The connecting post is slidably connected to the chute. The connecting post extends out of the chute. The end of the connecting post is fixed to the middle of the side of the second card seat.

[0007] Preferably, a convex post is embedded through the other end of the claw. The end of the convex post is rotatably connected to the first card seat. A connecting ring is coaxially embedded at the upper end of the suspension sleeve. The rear end of the connecting ring is fixed to the claw.

[0008] Preferably, the hanging and pressing member includes side seats extending on both sides of the pump base. An ear-turning frame is installed at the upper end of the side seat. One end of the ear-turning frame extends with a pressing ear, and the pressing ear presses against the edge of the base of the pump body. The other end of the ear-turning frame is rotatably installed with a Y-shaped frame, and the end of the Y-shaped frame is rotatably installed with a U-shaped hanging frame. The lower end of the hanging rod is embedded in the middle of the U-shaped hanging frame. Four positioning columns are arranged in a square matrix on the upper end surface of the pump base, and the positioning columns are inserted into the installation holes of the pump body.

[0009] Preferably, a guide sleeve is slidably installed on the vertical section of the U-shaped hanging frame. A support sleeve frame is fixedly installed at the upper end edge of the side seat, and the end of the support sleeve frame is fixed to the guide sleeve. A concave seat is fixedly installed on one side of the upper end of the side seat away from the support sleeve frame, and the ear-turning frame is rotatably installed inside the concave seat.

[0010] Preferably, the rotation and adjustment member includes two locking rod pins symmetrically and elastically installed at the lower edge of the outer surface of the hanging sleeve. A plurality of adjustment holes are linearly arranged in an array on both sides of the hanging rod, and one end of the locking rod pin is inserted into the inside of the adjustment hole. A groove locking ring is coaxially connected to the outer surface of the hanging sleeve near the lower edge, and the other end of the locking rod pin abuts against the groove of the groove locking ring.

[0011] Preferably, two pin support grooves are uniformly distributed on the inner surface of the groove locking ring. One side of the pin support groove is inclined, and one side of the pin support groove is communicated with the groove of the groove locking ring. The two pin support grooves are arranged in opposite directions. Two transfer frames are symmetrically and fixedly installed at the upper end of the groove locking ring, and a connecting ring is embedded between the ends of the two transfer frames. The connecting ring is rotatably installed on the hanging sleeve.

[0012] Preferably, a column sleeve is slidably installed on the outer surface of the locking rod pin. An angle block extends from the upper end of the column sleeve, and the end of the angle block is fixed to the hanging sleeve. A jacking spring is fixedly installed on the side surface of the column sleeve, and the end of the jacking spring is fixedly installed with a spring cap. The spring cap is embedded on the outer surface of the locking rod pin. One end edge of the locking rod pin is inclined, and the other end of the locking rod pin is spherical. A limiting rib extends on the outer surface of the hanging rod, and the limiting rib slidably penetrates through the inner wall of the hanging sleeve.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By means of the first clamping seat arranged obliquely and the second clamping seat arranged vertically, they can respectively adapt to the inclined bracket and the shed bracket for clamping. At this time, the pawl flips downward under the gravity of the pump body to press tightly against the inclined roof plate, and a lateral force is generated under the drive of the inclined surface of the inclined roof plate to firmly press the second clamping seat against the shed bracket, so that the second clamping seat and the first clamping seat can be firmly clamped between the shed bracket and the inclined bracket, so as to hang the pump body on the cattle and sheep shed racks, so as to prevent the cattle and sheep herds from kicking the pump body when entering and leaving the cattle and sheep sheds, thereby prolonging the service life of the piston vacuum pump and preventing the cattle and sheep from being injured.

[0014] 2. When the pump body is placed on the pump seat, the positioning posts on the pump seat will be correspondingly inserted into multiple mounting holes on the pump body. Subsequently, when the U-shaped hanging bracket is lifted, the Y-shaped frame will move and then drive the ear-turning frame to flip, so that the pressure ear at the end of the ear-turning frame can be pressed tightly against the edge of the base of the pump body, enabling the pump body to be firmly pressed and fixed on the pump seat and hung on the cattle shed. This process does not require separate fixing operations for the pump body, effectively facilitating the use.

[0015] 3. By rotating the groove lock ring, when the pin slot on the groove lock ring aligns with the lock rod pin, the ejecting spring will push the lock rod pin into the pin slot, enabling the lock rod pin to disengage from the adjustment hole to loosen the locking of the hanging rod, so that the hanging rod can slide in the hanging sleeve and extend to adaptively adjust the suspension height of the pump body, thereby adapting to the height of the cattle and sheep, enabling the breast pump to fully contact the cattle and sheep and meeting their milk sucking requirements.

The second card seat 9 is vertically arranged and can be engaged with the upright shed support 35. The opening direction of the second card seat 9 is opposite to the position where the first card seat 8 is located. The opening of the first card seat 8 faces backward, which can ensure that after they are engaged with the shed support 35 and the inclined support 36, there will be no front-back or left-right displacement. A pawl 31 is rotatably installed at the front end of the first card seat 8. An inclined roof plate 33 extends from the front end of the second card seat 9. One end of the pawl 31 abuts against the inclined roof plate 33. The cooperation between the pawl 31 and the inclined roof plate 33 can generate a lateral force to firmly press the second card seat 9 against the shed support 35, so that the second card seat 9 and the first card seat 8 can be firmly clamped between the shed support 35 and the inclined support 36. The hanging sleeve 7 is connected to the pawl 31. A rotation and adjustment member is provided between the hanging sleeve 7 and the suspension rod 18.

[0020] On the side of the first card seat 8, a top column 29 extends. A chute 26 is opened at the end of the top column 29. A prism cap 28 is slidably installed inside the chute 26. In the middle of the side of the prism cap 28, a connecting column 27 extends. The prism cap 28 functions to prevent the second card seat 9 from rotating. The cooperation between the chute 26 and the connecting column 27 functions to guide the second card seat 9. The connecting column 27 is slidably connected to the chute 26. The connecting column 27 extends out from the inside of the chute 26. The end of the connecting column 27 is fixed to the middle of the side of the second card seat 9. The top column 29 abuts against the second card seat 9, and can position the minimum distance between the second card seat 9 and the first card seat 8.

[0021] At the other end of the claw 31, a convex column 30 is inserted through and inlaid. The end of the convex column 30 is rotatably connected to the first card seat 8. The convex column 30 functions to connect the claw 31. At the upper end of the hanging sleeve 7, a connecting ring 32 is coaxially inlaid. The rear end of the connecting ring 32 is fixed to the claw 31. The connecting ring 32 functions to fix the hanging sleeve 7.

[0022] The hanging and pressing member includes side seats 2 extending on both sides of the pump base 20. At the upper end of the side seats 2, turning ear frames 24 are installed. The side seats 2 function to bear. At one end of the turning ear frame 24, a pressing ear 22 extends. The pressing ear 22 presses against the edge of the base of the pump body 1.

[0024] The tone conversion part includes two lock rod pins 19 symmetrically and elastically installed at the lower edge of the outer surface of the hanging sleeve 7. A plurality of adjustment holes 16 are linearly arranged in an array on both sides of the hanging rod 18. The cooperation between the lock rod pins 19 and the adjustment holes 16 can lock the hanging rod 18. One end of the lock rod pin 19 is inserted into the interior of the adjustment hole 16. A groove lock ring 6 is coaxially connected to the outer surface of the hanging sleeve 7 near the lower edge. The other end of the lock rod pin 19 abuts against the groove of the groove lock ring 6. The groove lock ring 6 can push the lock rod pin 19 to insert it into the adjustment hole 16.

[0025] Two pin support grooves 34 are evenly distributed on the inner surface of the groove lock ring 6. One side of the pin support groove 34 is inclined, which can ensure that the lock rod pin 19 located in the pin support groove 34 slides back into the groove on the groove lock ring 6 smoothly. One side of the pin support groove 34 is communicated with the groove of the groove lock ring 6. The two pin support grooves 34 are arranged in the opposite direction. Two transfer frames 11 are symmetrically and fixedly installed at the upper end of the groove lock ring 6. A connecting ring 10 is inlaid between the ends of the two transfer frames 11. The connecting ring 10 is rotatably installed on the hanging sleeve 7. The connecting ring 10 plays a connecting role.

[0026] A column sleeve 13 is slidably installed on the outer surface of the lock rod pin 19. An angle block 12 extends from the upper end of the column sleeve 13. The column sleeve 13 plays a role in guiding the lock rod pin 19. The end of the angle block 12 is fixed to the hanging sleeve 7. The angle block 12 plays a role in fixing the column sleeve 13. A top spring 14 is fixedly installed on the side of the column sleeve 13. The end of the top spring 14 is fixedly installed with a spring cap 15. The spring cap 15 is inlaid on the outer surface of the lock rod pin 19. The spring cap 15 plays a role of being pushed by the top spring 14. The top spring 14 plays a role of pushing the lock rod pin 19 out of the adjustment hole 16. One end edge of the lock rod pin 19 is inclined, which is convenient for inserting into the adjustment hole 16. The other end of the lock rod pin 19 is spherical, which is convenient for sliding in the groove of the groove lock ring 6. A limiting edge 17 extends from the outer surface of the hanging rod 18. The limiting edge 17 plays a role of preventing the hanging rod 18 from rotating. The limiting edge 17 slidably penetrates through the inner wall of the hanging sleeve 7.

[0027] During use, when the pump body 1 is placed on the pump base 20, the positioning posts 21 on the pump base 20 will correspondingly be inserted into a plurality of mounting holes on the pump body 1. Subsequently, the U-shaped hanger 5 is lifted. At this time, the Y-shaped frame 25 will move, thereby driving the ear-turning frame 24 to turn over, so that the pressure ear 22 at the end of the ear-turning frame 24 can be pressed against the edge of the base of the pump body 1, enabling the pump body 1 to be firmly pressed and fixed on the pump base 20. Subsequently, the U-shaped hanger 5 is continuously lifted, so that the first card seat 8 can approach the inclined support 36 and be clamped on the inclined support 36. Subsequently, the first card seat 8 slides up and down on the inclined support 36, enabling the second card seat 9 to gradually approach and be clamped on the shed support 35. At this time, the end of the ejector post 29 abuts against the second card seat 9. Then, the U-shaped hanger 5 is released, so that the claw 31 turns downward under the gravity of the pump body 1 to abut tightly against the inclined roof plate 33, and a lateral force is generated under the drive of the inclined surface of the inclined roof plate 33 to firmly press the second card seat 9 against the shed support 35, enabling the second card seat 9 and the first card seat 8 to be firmly clamped between the shed support 35 and the inclined support 36, so as to suspend the pump body 1 on the cattle and sheep shed frame to prevent the cattle and sheep herd from kicking the pump body 1 when entering and leaving the cattle and sheep shed. Then, the groove lock ring 6 is rotated according to the height of the cattle and sheep. When the pin slot 34 on the groove lock ring 6 is aligned with the lock rod pin 19, the ejecting spring 14 will push the lock rod pin 19 into the pin slot 34, enabling the lock rod pin 19 to disengage from the adjusting hole 16, so as to loosen the locking of the suspension rod 18, enabling the suspension rod 18 to slide and extend within the suspension sleeve 7 to adaptively adjust the suspension height of the pump body 1, allowing the breast pump to be in full contact with the cattle and sheep. Subsequently, the pump body 1 can be used to generate suction to suck the cattle and sheep through the breast pump.
