Detailed Description

The utility model is described in further detail below with reference to the figures and the embodiments.

In the attached fig. 1 and fig. 2, a sliding type hydrostatic balance device includes a support 10, a ball transmission assembly, a digital display balance 30 and an overflow bucket 40.

Two sides of the bracket 10 in the length direction are respectively provided with a pin hole 12. One end of the bracket 10 is provided with a bracket rod 11, and the bracket rod 11 improves the stability of the bracket 10. One side of the bracket 10 in the length direction is embedded with a bubble level gauge 15. The bubble level 15 is provided on the upper side of the overflow bucket 40. The pin hole 12 is also provided at the upper side of the overflow bucket 40.

The ball drive assembly includes at least one lead screw 20, and preferably two lead screws 20. One end of the screw 20 is provided with a stop 21, and the pin hole 12 is disposed near the stop 21. The lead screw 20 is mounted at the top end of the bracket 10. The ball gear assembly is disposed at the top end of the bracket 10.

The bottom end of the digital balance 30 is provided with a hook 31. The bottom end of the digital balance 30 is also provided with a bottom plate 32. A positioning hole 33 is formed at one side of the bottom plate 32 in the length direction. The base plate 32 is slidably connected to the lead screw 20. The positioning hole 33 is inserted into the pin hole 12 through the positioning pin 22. The digital balance 30 is arranged on the upper side of the ball transmission assembly and is connected with the ball transmission assembly in a sliding mode.

The overflow tub 40 is provided with an inner tub 45. The overflow bucket 40 is provided at the bottom end of the support frame 10. An overflow pipe 41 is arranged at the side wall of the overflow barrel 40. The liquid overflowing the overflow barrel 40 is discharged through the overflow pipe 41, and the front and rear water level lines are kept constant. The inner barrel 45 is connected with the digital balance 30 through a hook 31. The overflow pipe 41 is provided with a valve 42. The overflow pipe 41 is disposed higher than the inner tub 45.

The device is provided with a ball transmission assembly under a digital display balance 30. The digital display balance 30 is repeatedly adjusted to be horizontal, the bubble level meter 15 is additionally arranged on the support 10, and after the support 10 is horizontal, the digital display balance 30 supported on the support 10 does not need to be repeatedly adjusted to be horizontal. The digital balance 30 slides, and the positioning hole 33 is preset on the sliding bottom plate 32 to prevent the digital balance 30 from displacing in the sliding process. One end of the screw rod 20 is provided with a stop block 21 and a pin hole 12, and the digital display balance 30 can be locked in time after being positioned in a sliding manner, so that the influence of secondary sliding on the test is avoided. And the digital balance 30 usually has a certain shake after the sample is taken by the hook 31, which results in unstable reading. At this time, the positioning pin 22 is not locked temporarily, and damping can be formed by sliding of the digital display balance 30, so that the sample can be stabilized as soon as possible, and then the positioning pin 22 is locked, so that a stable reading can be obtained conveniently.

The above is only a specific application example of the present invention, and the protection scope of the present invention is not limited in any way. All the technical solutions formed by equivalent transformation or equivalent replacement fall within the protection scope of the present invention.
