[0008] The present invention is further configured such that the anti-counterclockwise rotation mechanism includes a slide block, and a plurality of slide grooves are evenly arranged on the inner side wall of the connecting tube. The slide block slides in conjunction with the slide grooves. A second compression spring is arranged inside the slide grooves. A plurality of second triangular teeth that are adapted to the first triangular teeth are fixedly connected to one end of the slide block near the reinforcing seat to prevent the reinforcing seat from rotating counterclockwise.

[0009] The present invention is further configured such that a slide rod is slidably provided on the side end of the slide block, the slide rod is slidably engaged with the connecting pipe, the second compression spring is sleeved on the outside of the slide rod, and a limit plate is fixedly connected to the side end of the slide rod to limit the slide block.

[0010] The present invention is further configured such that an annular groove is provided on the connecting pipe, and a circular ring is fixedly connected to the outside of the reinforcing base, the circular ring being rotatably connected to the annular groove to ensure stable rotation of the reinforcing base.

[0011] The present invention is further configured such that a baffle is installed at the top of the connecting pipe, the side end of the baffle contacts the side end of the ring, and a sealing gasket is provided between the baffle and the connecting pipe to ensure the sealing of the connection between the baffle and the connecting pipe.

[0012] The present invention is further configured such that a circular groove is provided on the baffle, and a rotating column is rotatably connected inside the circular groove. The side end of the rotating column is fixedly connected to the side end of the reinforcing base, and a rotating handle is fixedly connected to the side end of the rotating column to facilitate the rotation of the reinforcing base.

[0013] The present invention is further provided with an annular groove on the outer side of the circular groove, and a sealing ring inside the annular groove to ensure the sealing of the connection between the rotating column and the baffle.

[0014] The present invention is further configured such that a sealing sleeve is fixedly connected to the side end of the connecting pipe, and the sealing sleeve abuts against the connecting disc to ensure the sealing between the connecting pipe and the connecting disc.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a firmly connected sand pump casing, which has the following beneficial effects:

[0017] 1. Pull the connecting tube away from the housing to the furthest position. Then rotate the connecting tube and the reinforcing base to the position corresponding to the screw. Then release the connecting tube and push the round tube to move through the first compression spring, so that the screw is inserted into the regular hexagonal groove on the reinforcing base. At the same time, the anti-counterclockwise rotation mechanism prevents the reinforcing base and screw from rotating counterclockwise, thereby preventing the screw from rotating counterclockwise and avoiding the screw from loosening during the use of the sand pump, ensuring the firmness of the connection between the housing and the connecting plate.

[0018] 2. The slide block is moved by the second compression spring, so that multiple second triangular teeth engage with multiple first triangular teeth. At this time, the hypotenuse of the first triangular teeth contacts the hypotenuse of the second triangular teeth. When the reinforcing seat is rotated clockwise, the second triangular teeth squeeze the first triangular teeth, causing the slide block to move inward to the inside of the groove. This makes it easier to rotate the reinforcing seat clockwise, adjust the regular hexagonal groove to a suitable angle according to the screw angle, and fit the reinforcing seat onto the outside of the screw.

[0019] 3. The first compression spring pushes the round tube, connecting seat, connecting pipe and sealing sleeve to move, so that the sealing sleeve is pressed against the connecting plate. The sealing sleeve ensures the sealing between the connecting pipe and the connecting plate. At the same time, the sealing gasket and sealing ring ensure the sealing between the baffle and the connecting pipe and the connection between the rotating column and the baffle. This can effectively prevent water from entering the interior of the connecting pipe, prevent water from contacting the screw, prevent the screw from being corroded and damaged, and facilitate the disassembly of the screw later.

[0031] Please see Figures 1-7 A securely connected sand pump casing includes a casing 1. A connecting plate 3 is connected to the side end of the casing 1 by multiple screws 2. A circular plate 4 is fixedly connected to the connecting plate 3. A cylinder 5 is fixedly connected to the side end of the circular plate 4. A circular tube 6 is rotatably and slidably connected to the outside of the cylinder 5. A top plate 7 is fixedly connected to the side end of the cylinder 5. A first compression spring 8 is provided between the top plate 7 and the cylinder 5. The first compression spring 8 is sleeved on the outside of the cylinder 5. A connecting pipe 10 is connected to the side end of the circular tube 6 by a connecting seat 9. A reinforcing seat 11 is rotatably connected to the connecting pipe 10. The bottom end of the reinforcing seat 11 is provided with a regular hexagonal groove 12 that matches the screws 2. Multiple first triangular teeth 13 are evenly provided on the outside of the reinforcing seat 11. Multiple anti-counterclockwise rotation mechanisms are provided on the connecting pipe 10 to reinforce the screws 2, prevent the screws 2 from loosening, and ensure the secure connection between the connecting plate 3 and the casing 1.

[0032] Specifically, the connecting pipe 10 is pulled to the side away from the housing 1 and pulled to the farthest position. Then, the connecting pipe 10 and the reinforcing base 11 are rotated to the position corresponding to the screw 2. Then, the connecting pipe 10 is released, and the round tube 6 is pushed to move by the first compression spring 8, so that the screw 2 is inserted into the inside of the regular hexagonal groove 12 on the reinforcing base 11. At the same time, the anti-counterclockwise rotation mechanism prevents the reinforcing base 11 and the screw 2 from rotating counterclockwise, thereby preventing the screw 2 from rotating counterclockwise and preventing the screw 2 from becoming loose during the use of the sand pump, thus ensuring the firmness of the connection between the housing 1 and the connecting plate 3.

[0033] Please see Figure 5 and Figure 6The anti-counterclockwise rotation mechanism includes a slide block 14. Multiple slide grooves 15 are evenly arranged on the inner side wall of the connecting pipe 10. The slide block 14 slides in conjunction with the slide grooves 15. A second compression spring 16 is arranged inside the slide groove 15. Multiple second triangular teeth 17 that are adapted to the first triangular teeth 13 are fixedly connected to one end of the slide block 14 near the reinforcing seat 11 to prevent the reinforcing seat 11 from rotating counterclockwise. A slide rod 18 is slidably arranged on the side end of the slide block 14. The slide rod 18 slides in conjunction with the connecting pipe 10. The second compression spring 16 is sleeved on the outside of the slide rod 18. A limit plate 19 is fixedly connected to the side end of the slide rod 18 to limit the slide block 14.

[0034] Specifically, the second compression spring 16 pushes the slide 14 to move, so that multiple second triangular teeth 17 engage with multiple first triangular teeth 13. At this time, the hypotenuse of the first triangular teeth 13 contacts the hypotenuse of the second triangular teeth 17. When the reinforcing seat 11 is rotated clockwise, the second triangular teeth 17 squeeze the first triangular teeth 13, causing the slide 14 to move towards the inside of the slide groove 15. This facilitates the clockwise rotation of the reinforcing seat 11, makes it easier to adjust the regular hexagonal groove 12 to a suitable angle according to the angle of the screw 2, and makes it easier to fit the reinforcing seat 11 onto the outside of the screw 2.

[0035] Please see Figures 3-7 The connecting pipe 10 is provided with an annular groove 20. A ring 21 is fixedly connected to the outside of the reinforcing base 11. The ring 21 is rotatably connected to the annular groove 20 to ensure the stable rotation of the reinforcing base 11. A baffle 22 is installed at the top of the connecting pipe 10. The side end of the baffle 22 contacts the side end of the ring 21. A sealing gasket 23 is provided between the baffle 22 and the connecting pipe 10 to ensure the sealing of the connection between the baffle 22 and the connecting pipe 10. A circular groove 24 is provided on the baffle 22. The inside of the circular groove 24 is rotatably connected. A rotating column 25 is connected to the side end of the reinforcing base 11. A rotating handle 26 is fixedly connected to the side end of the rotating column 25 to facilitate the rotation of the reinforcing base 11. An annular groove 27 is provided on the outer side of the circular groove 24. A sealing ring 28 is provided inside the annular groove 27 to ensure the sealing of the connection between the rotating column 25 and the baffle 22. A sealing sleeve 29 is fixedly connected to the side end of the connecting pipe 10. The sealing sleeve 29 abuts against the connecting plate 3 to ensure the sealing of the connection between the connecting pipe 10 and the connecting plate 3.

[0036] Specifically, the first compression spring 8 pushes the round tube 6, connecting seat 9, connecting pipe 10 and sealing sleeve 29 to move, so that the sealing sleeve 29 abuts against the connecting plate 3. The sealing sleeve 29 ensures the sealing between the connecting pipe 10 and the connecting plate 3. At the same time, the sealing gasket 23 and sealing ring 28 ensure the sealing between the baffle 22 and the connecting pipe 10 and the sealing between the rotating column 25 and the baffle 22. This can effectively prevent water from entering the interior of the connecting pipe 10, prevent water from contacting the screw 2, prevent the screw 2 from being corroded and damaged, and facilitate the disassembly of the screw 2 later.

[0037] In summary, when using the overall equipment:

[0038] First, rotate the round tube 6, connecting seat 9, connecting tube 10, and reinforcing seat 11 to rotate the connecting tube 10 and reinforcing seat 11 to one side of the screw 2 insertion hole on the connecting plate 3. Then, install the connecting plate 3 onto the housing 1 using multiple screws 2. Next, pull the connecting tube 10 away from the housing 1 to the furthest position. Then, rotate the connecting tube 10 and reinforcing seat 11 to the position corresponding to the screw 2. Then, release the connecting tube 10, and the first compression spring 8 will push the round tube 6, connecting seat 9, connecting tube 10, and reinforcing seat 11 downwards. If the angle of the regular hexagonal slot 12 corresponds to that of the screw 2, the screw 2 is inserted into the interior of the regular hexagonal slot 12. If the angle of the screw 2 does not correspond to that of the regular hexagonal slot 12, the handle 26, the rotating column 25, and the reinforcing seat 11 are slowly rotated clockwise. When the angle of the regular hexagonal slot 12 and the screw 2 are aligned, the reinforcing seat 11 is pushed downward by the action of the first compression spring 8, so that the screw 2 is inserted into the interior of the regular hexagonal slot 12. The reinforcing seat 11 is fitted over the outside of the screw 2 and the anti-counterclockwise rotation mechanism prevents the screw 2 from rotating in the opposite direction.
