Technical Field
[0001] This utility model relates to the field of milking cup inner sleeve material handling technology, specifically a milking cup inner sleeve gripping device for milking cows. Background Technology
[0002] In the dairy farming industry, milking equipment is an essential tool in daily production. Milking cups typically consist of an outer shell and an inner elastic sleeve, which needs to be replaced or cleaned periodically after a period of use. However, because the inner sleeve fits tightly to the outer shell, and may stick together due to milk stains, dirt, or aging after long-term use, manually removing the inner sleeve is quite difficult. Traditionally, workers usually have to pry the inner sleeve out of the outer shell by hand.
[0003] This method is not only time-consuming and labor-intensive, but it also easily leads to hand fatigue or injury for workers. This problem is particularly pronounced in large dairy farms that handle hundreds of milking cups daily.
[0004] Therefore, we propose a milk cup inner sleeve gripping device for milking cows. Utility Model Content
[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a milk cup inner sleeve gripping device for dairy cow milking, specifically designed to assist workers in removing the milk cup inner sleeve, thereby improving the efficiency of removal and effectively solving the problems in the background technology.

A through hole is provided in the middle of the upper end of the column groove, and the through hole extends to the middle of the lower end of the mounting cavity. A locking structure is installed in the mounting cavity, and a gripping structure is provided in the guide groove. The locking structure includes a cylinder, a cylindrical slider and a double-sloping extrusion block. The gripping structure includes a first arc-shaped block, a second arc-shaped block, an upper guide slope, a lower guide slope, an arc-shaped protrusion, a limiting slider and a compression spring. The second arc-shaped block is fixed to the outer wall of the first arc-shaped block. The upper guide slope is opened on the inner wall of the first arc-shaped block, and the lower guide slope is opened at the lower end of the outer wall of the second arc-shaped block.
[0007] Preferably, the cylinder is fixed in the mounting cavity, and the piston rod in the cylinder moves through the through hole. The cylindrical slider and the double-sloping extrusion block are located in the cylindrical groove. The double-sloping extrusion block is fixed on the lower outer surface of the cylindrical slider, and the middle part of the upper outer surface of the cylindrical slider is fixedly connected to the lower outer surface of the piston rod in the cylinder.
[0008] Preferably, the outer wall of the cylindrical slider and the cylindrical groove are slidably connected.
[0009] Preferably, there are two sets of the first arc-shaped block, the second arc-shaped block, and the limiting slider. The outer walls of the first arc-shaped block and the second arc-shaped block are slidably connected to the guide groove. The double-sloping extrusion block is located on the upper part between the two sets of the first arc-shaped blocks.
[0010] Preferably, the arc-shaped protrusions are disposed on the upper and lower sides of the outer wall of the second arc-shaped block.
[0011] Preferably, the limiting slider is fixed in the middle of the lower outer surface of the first arc-shaped block, and the outer wall of the limiting slider is slidably connected to the limiting mounting groove, and the compression spring is fixed between the two sets of limiting sliders.
[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a milk cup inner sleeve gripping device for milking cows, which has the following beneficial effects: 1. This is a milk cup inner sleeve gripping device for milking cows. By setting an automatically locking gripping structure, the device uses a cylinder to drive the double inclined extrusion blocks to press down, causing the first arc-shaped block and the second arc-shaped block to expand outward and tightly abut against the inner wall of the milk cup inner sleeve, thus achieving reliable gripping of the inner sleeve. This mechanical locking method is simple to operate and labor-saving, effectively avoiding the difficulty of manually prying the inner sleeve by hand in the traditional way, and reducing the labor intensity of operators.
[0013] 2. The milk cup inner sleeve gripping device for milking cows has an arc-shaped protrusion on the outer side of the second arc-shaped block of the gripping structure, which increases the friction with the inner wall of the inner sleeve. This effectively prevents slippage during gripping and pulling out, avoids the inner sleeve from falling off midway, and improves the success rate of gripping and operational stability.

[0020] This embodiment is a milk cup inner sleeve gripping device for milking cows.
[0021] like Figure 1-4 As shown, the device includes a cylindrical plug rod 1. A handle glove 4 is fixedly installed on the upper outer wall of the cylindrical plug rod 1. A control switch 5 is installed on one side of the handle glove 4. An installation cavity 9 is formed inside the upper end of the cylindrical plug rod 1. A guide groove 7 is formed on the lower part of the outer surface of one side of the cylindrical plug rod 1, extending through to the other outer surface of the cylindrical plug rod 1. A cylindrical groove 6 is provided in the middle of the upper end of the guide groove 7, and a limiting installation groove 8 is provided in the middle of the lower end of the guide groove 7. A through hole 10 is formed in the middle of the upper end of the cylindrical groove 6, extending through to the middle of the lower end of the installation cavity 9. A locking structure 3 is installed in the mounting cavity 9, and a gripping structure 2 is provided in the guide groove 7. The locking structure 3 includes a cylinder 11, a cylindrical slider 12, and a double-sloping extrusion block 13. The gripping structure 2 includes a first arc-shaped block 14, a second arc-shaped block 15, an upper guide slope 16, a lower guide slope 17, an arc-shaped protrusion 18, a limiting slider 19, and a compression spring 20. The second arc-shaped block 15 is fixed to the outer wall of the first arc-shaped block 14. The upper guide slope 16 is opened on the inner wall of the first arc-shaped block 14, and the lower guide slope 17 is opened at the lower end of the outer wall of the second arc-shaped block 15.
[0022] Cylinder 11 is fixed in mounting cavity 9, and the piston rod in cylinder 11 moves through through hole 10. Cylindrical slider 12 and double-sloping extrusion block 13 are located in cylindrical groove 6. Double-sloping extrusion block 13 is fixed to the lower outer surface of cylindrical slider 12. The middle part of the upper outer surface of cylindrical slider 12 is fixedly connected to the lower outer surface of piston rod in cylinder 11. The outer wall of cylindrical slider 12 is slidably connected to cylindrical groove 6. The first arc block 14, the second arc block 15 and the limiting slider 19... There are two sets of each. The outer walls of the first arc-shaped block 14 and the second arc-shaped block 15 are slidably connected to the guide groove 7. The double-sloping extrusion block 13 is located on the upper part between the two sets of the first arc-shaped blocks 14. The arc-shaped protrusion 18 is set on the upper and lower sides of the outer wall of the second arc-shaped block 15.

The lower end of the cylindrical plug rod 1 is inserted into the milking cup. During insertion, the lower guide slope 17 at the lower end of the second arc-shaped block 15 is squeezed, causing both sets of second arc-shaped blocks 15 to slide along the guide groove 7. The lower guide slope 17 drives the first arc-shaped block 14 to slide along the guide groove 7. The first arc-shaped block 14 drives the limiting slider 19 to squeeze the compression spring 20. The elastic force of the compression spring 20 drives the second arc-shaped block 14 to slide along the guide groove 7. The two arc-shaped blocks 15 contact and press against the inner wall of the inner sleeve. The arc-shaped protrusions 18 improve the anti-slip properties. Then, the rotation of the mounting cavity 9 drives the cylindrical slider 12 to descend along the cylindrical groove 6. The double-sloping extrusion block 13 is inserted between the upper guide slope 16 on one side of the two sets of first arc-shaped blocks 14. The double-sloping extrusion block 13 limits the first arc-shaped block 14, thereby limiting the second arc-shaped block 15 and preventing the second arc-shaped block 15 from retracting. Then, the cylindrical plug rod 1 is pulled out. The cylindrical plug rod 1 removes the inner sleeve through the second arc-shaped block 15. Compared with manual pressing, this is more convenient and labor-saving, reducing the labor intensity of the workers.
