DETAILED DESCRIPTION OF THE INVENTION

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0030] As Figure 1 and Figure 2 shown, an installation structure includes: a bottom plate 20, the bottom plate 20 is in a rectangular plate shape, the top of the bottom plate 20 is movably connected with a connecting plate 22, a connecting groove 21 is opened at the top of the bottom plate 20, the connecting grooves 21 are evenly opened at the four corners of the top of the bottom plate 20, and the same number of connecting grooves 21 are also opened at the top of the connecting plate 22. This is the existing technology, so it will not be elaborated here.

[0031] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a quick - installation structure is provided on the wall surface of the connecting plate 22 for quickly combining the connecting plate 22 and the bottom plate 20. The quick - installation structure includes: a screw barrel 30, a moving column 34, an expanding cone 36, and a driving disk 43. The screw barrel 30 is snap - connected in the connecting groove 21. The moving column 34 is threadedly connected to the wall surface of the screw barrel 30. The expanding cone 36 is fixedly connected to the bottom of the moving column 34. The driving disk 43 is rotatably connected above the connecting plate 22. The same screw barrel 30, moving column 34, and expanding cone 36 are provided in each connecting groove 21.

[0032] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the screw barrel 30 is in the shape of a hollow circular tube. The moving column 34 is threadedly connected in the cavity of the screw barrel 30. The lower half of the moving column 34 is inside the screw barrel 30, and the upper half of the moving column 34 is above the screw barrel 30. The expanding cone 36 is conical. The inner dimension of the cavity of the screw barrel 30 is the same as the minimum arc - diameter of the top of the expanding cone 36. The upper half of the moving column 34 is provided with teeth. The driving disk 43 is disk - shaped, and the arc surface of the driving disk 43 is provided with teeth that can mesh with the wall surface of the moving column 34. The driving disks 43 are symmetrically arranged above the connecting plate 22, and each driving disk 43 can mesh with the symmetrically arranged moving columns 34 on each side. The quick - installation structure further includes a limiting ring 31, an expanding groove 32, a limiting ring 33, and a limiting groove 35. The limiting ring 31 is fixedly connected to the top of each screw barrel 30 respectively. The expanding groove 32 is opened at the bottom of each screw barrel 30. The limiting ring 33 is fixedly connected in the cavity of each screw barrel 30 respectively. The limiting groove 35 is opened at the bottom of each moving column 34. The expanding groove 32 is a rectangular groove and is symmetrically opened at the bottom of the screw barrel 30. The limiting ring 31 is a semi - circular ring, and the size of the limiting ring 31 is larger than that of the screw barrel 30. The limiting groove 35 can slide adaptively with the circular - ring - shaped limiting ring 33;

[0033] During specific use, align all the connecting grooves 21 at the top of the bottom plate 20 with the connecting grooves 21 at the top of the connecting plate 22. Then place the screw barrel 30 in each connecting groove 21 and adjust the moving column 34 to mesh with the wall surface of the driving disk 43. At this time, rotate the driving disk 43. The driving disk 43 can drive the symmetrically arranged moving columns 34 on each side to rotate synchronously when rotating. The moving column 34 can drive the expanding cone 36 to move upward when rotating. The arc surface of the expanding cone 36 can expand the bottom of the screw barrel 30, making the bottom size of the screw barrel 30 larger than that of the connecting groove 21. After the connecting plate 22 and the bottom plate 20 stop shaking, stop rotating the driving disk 43. When disassembling, rotate the driving disk 43 in the opposite direction, thereby driving the moving column 34 to move downward, so that the expanding cone 36 no longer expands the bottom of the screw barrel 30. Then take out the screw barrel 30 in each connecting groove 21 to complete the disassembly;

[0034] In summary, by setting up the quick-installation structure, the bottom plate 20 and the connecting plate 22 can be assembled quickly. The quick-installation structure controls the moving columns 34 symmetrically on each side through the driving disks 43 on each side to achieve quick installation. Therefore, compared with the prior art, the installation speed of this solution is faster and simpler.

[0035] As Figure 4 and Figure 5 shown, a self-locking structure is provided at the top of the connecting plate 22. The self-locking structure includes a base plate 40, side plates 41, ball bearings 42, and locking grooves 44. The base plates 40 are symmetrically and fixedly connected to the top of the connecting plate 22. The top of each base plate 40 is rotatably connected to the corresponding driving disk 43. The side plates 41 are symmetrically and fixedly connected to both sides of the connecting plate 22. The ball bearings 42 are elastically connected to the top of each side plate 41. The locking grooves 44 are formed at the bottom of the driving disk 43. A cylindrical groove for the ball bearing 42 of a spherical shape to slide is formed at the top of the side plate 41. The ball bearing 42 is elastically connected to the cylindrical groove at the top of the side plate 41 through a spring. The locking groove 44 is a hemispherical groove. A plurality of locking grooves 44 are formed in an annular array at the bottom of each driving disk 43. Each locking groove 44 can adapt to the size of the ball bearing 42;

[0036] During specific use, when the driving disk 43 is rotated, the ball bearing 42 will be pushed by the spring at its bottom into the locking groove 44. When the rotation of the driving disk 43 stops, half of the ball bearing 42 will enter the locking groove 44;

[0037] In summary, by setting up the self-locking structure, the position of the driving disk 43 can be simply limited, preventing the driving disk 43 from automatically rotating due to inertia when not rotated, thereby driving the moving column 34 to rotate automatically and affecting the work. Therefore, the self-locking structure can effectively prevent the driving disk 43 from automatically rotating.

[0038] A metering pump includes a pump body (not shown in the figure), and also includes an installation structure as described above. The pump body is fixedly connected to the top of the connecting plate 22;

[0039] By setting up the installation structure, the metering pump can be assembled and used quickly, effectively saving the installation steps and time.

[0040] Working principle: Align all the connecting grooves 21 on the top of the bottom plate 20 with the connecting grooves 21 on the top of the connecting plates 22. Then place the screw cylinders 30 in each connecting groove 21, and adjust the moving columns 34 to engage with the wall surface of the driving disc 43. At this time, rotate the driving disc 43. The driving disc 43 can drive the symmetrically arranged moving columns 34 on each side to rotate synchronously when rotating. The moving columns 34 can drive the expanding cones 36 to move upward when rotating. The arc surface of the expanding cones 36 can expand the bottom of the screw cylinders 30, so that the bottom size of the screw cylinders 30 is larger than that of the connecting grooves 21. After the connecting plates 22 and the bottom plate 20 stop shaking, stop rotating the driving disc 43. When disassembly is required, rotate the driving disc 43 in the opposite direction, thereby driving the moving columns 34 to move downward, so that the expanding cones 36 no longer expand the bottom of the screw cylinders 30. Then take out the screw cylinders 30 in each connecting groove 21 to complete the disassembly.
