Description

Technical Field

[0001] This utility model relates to the field of metering pump technology, specifically to a miniature diaphragm metering pump housing. Background Technology

[0002] Diaphragm metering pumps utilize a specially designed and manufactured flexible diaphragm to replace the piston, achieving reciprocating motion under the action of a drive mechanism to complete the suction and discharge process. Due to the isolating effect of the diaphragm, electric diaphragm pumps structurally achieve true isolation between the metered fluid and the drive lubrication mechanism. Existing diaphragm metering pumps are widely used; for example, miniature metering pumps can be used for quantitative delivery in pharmaceuticals.

[0003] In the prior art, CN221800077U discloses a miniature diaphragm metering pump housing. However, the prior art can only adjust one angle when adjusting the installation angle of the metering pump. For example, if the height, horizontal position, or angle of the pipe interface (such as the inlet or outlet) is inconsistent with the metering pump interface, or if the interface is biased to one side, misaligned vertically, or tilted at a certain angle, it is often necessary to adjust another angle. If only the angle in a single direction can be adjusted, it will lead to greater limitations in the installation of the metering pump, and may even cause pipe twisting or pump body stress after connection. It has poor practicality and flexibility. In view of this, we propose a miniature diaphragm metering pump housing to solve the above problems. Utility Model Content

[0023] Please see Figures 1-5This utility model provides a technical solution: a micro diaphragm metering pump housing, including a base plate 1, a connecting plate 2 on the upper side of the base plate 1, an mounting plate 3 on the upper side of the connecting plate 2, a metering pump housing 4 on the upper side of the mounting plate 3, two L-shaped fixing plates 24 fixedly connected to the upper surface of the mounting plate 3, fixing components 5 on the outside of the L-shaped fixing plates 24, a movable groove 6 opened on the lower surface of the mounting plate 3, a first sphere 7 movably fitted inside the movable groove 6, a support rod 8 fixedly connected to the lower surface of the first sphere 7, and the support rod 8 fixedly connected to the upper surface of the connecting plate 2. The lower surface of the mounting plate 3 has two limiting grooves 9. The internal structure of the two limiting grooves 9 is the same. Therefore, the following description focuses on the internal structure of one limiting groove 9. A second ball 10 is movably fitted inside the limiting groove 9. The centers of the first ball 7 and the second ball 10 are located on the same axis. A lifting rod 11 is fixedly connected to the lower surface of the second ball 10. A fixing rod 12 is provided outside the lifting rod 11. A lifting groove 13 is provided inside the fixing rod 12. The lifting rod 11 is slidably connected inside the lifting groove 13. An adjustment component is provided inside the lifting groove 13.

[0024] In the above embodiment, the metering pump housing 4 is located on the lower side of the two L-shaped fixing plates 24 and is fixedly installed by means of fixing components 5. The fixing method of fixing components 5 and metering pump housing 4 is prior art, and metering pump housing 4 is also prior art. For details, please refer to the prior art with announcement number CN221800077U. The working principle of this solution is the same as that prior art, so it will not be described in detail in this document.

[0025] The adjustment assembly includes an adjustment screw 14, which is rotatably connected to the bottom wall of the lifting groove 13, and a lifting rod 11 is threaded onto the outside of the adjustment screw 14.

[0026] The lifting rod 11 is rectangular in shape, and the lifting groove 13 is a rectangular groove that matches the lifting rod 11.

[0027] The fixed rod 12 has an annular through groove 15 on its outside. The annular through groove 15 is connected to the lifting groove 13. The adjusting screw 14 is fixedly sleeved with a toggle knob 16. The toggle knob 16 is located inside the annular through groove 15 and extends out of the fixed rod 12 through the annular through groove 15.

[0028] The upper surface of the base plate 1 is provided with a first guide groove 17, and a first threaded rod 18 is rotatably connected inside the first guide groove 17. A guide block 19 is threaded on the outside of the first threaded rod 18, and the guide block 19 is slidably connected inside the first guide groove 17.

[0029] The lower surface of the connecting plate 2 is provided with a second guide groove 20, and the upper end of the guide block 19 extends into the interior of the second guide groove 20. The upper end of the guide block 19 is slidably connected to the interior of the second guide groove 20.

[0030] The second guide groove 20 is rotatably connected to the second threaded rod 21, and the upper end of the guide block 19 is threadedly sleeved on the outside of the second threaded rod 21.

[0031] The left end of the first threaded rod 18 and the front end of the second threaded rod 21 respectively rotate through the interior of the base plate 1 and the connecting plate 2, and the ends of the first threaded rod 18 and the second threaded rod 21 are fixedly connected to handles 22.

[0032] A number of ball bearings 23 are movably sleeved on the lower surface of the connecting plate 2. The connecting plate 2 contacts the base plate 1 through the ball bearings 23. The setting of the ball bearings 23 further reduces the friction between the connecting plate 2 and the base plate 1, thereby ensuring the smooth movement of the connecting plate 2 on the base plate 1.

[0033] Working principle:

[0034] When using the micro diaphragm metering pump housing, if it is necessary to adjust the angle of the metering pump housing 4, the second ball 10 must first be reset so that its bottom surface abuts against the top surface of the fixing rod 12, at which point the mounting plate 3 is in a horizontal state.

[0035] When the operator needs to adjust the angle of the metering pump housing 4 in the left and right directions, they press their finger on the surface of the toggle knob 16 inside the left fixed rod 12, causing the toggle knob 16 to rotate. The rotation of the toggle knob 16 will drive the rotation of the adjusting screw 14, which in turn will cause the lifting rod 11 to slide inside the lifting groove 13. The movement of the lifting rod 11 will cause the movement of the second ball 10 on the left side. At this time, the second ball 10 on the left side will move inside the left limiting groove 9, thereby causing the mounting plate 3 to rotate around the center of the first ball 7 and the second ball 10 on the front side, thus realizing the adjustment of the left and right angle of the mounting plate 3, and finally realizing the adjustment of the left and right angle of the metering pump housing 4.

[0036] When the angle adjustment in the front and rear directions is required, make the mounting plate 3 horizontal again, and then operate the front toggle knob 16 in the same way. At this time, the second ball 10 on the front side will slide inside the front limiting groove 9. The mounting plate 3 will rotate around the center of the first ball 7 and the second ball 10 on the left side, thereby realizing the adjustment of the angle in the front and rear directions of the mounting plate 3, and finally realizing the adjustment of the angle in the front and rear directions of the metering pump housing 4.

[0037] When it is necessary to fine-tune the installation position of the metering pump housing 4, the left handle 22 is rotated. The left handle 22 will drive the first threaded rod 18 to rotate. The rotation of the first threaded rod 18 will drive the guide block 19 to slide inside the first guide groove 17. At this time, the guide block 19 is stationary in the second guide groove 20, and finally the connecting plate 2 will be displaced in the left and right directions.

[0038] When it is necessary to adjust the position of the metering pump housing 4 in the front-to-back direction, rotate the front handle 22. At this time, because the guide block 19 is fixed in the position inside the first guide groove 17, it will drive the connecting plate 2 to move in the front-to-back direction on the upper surface of the base plate 1, and finally realize the fine adjustment of the position of the metering pump housing 4 during installation.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
