Abstract
The present invention discloses a hydraulic balance for weighing items. The hydraulic balance comprises a base, a horizontal level gauge arranged on the base, a vertically arranged U-shaped tube, and a tray support rod. The base is fixedly provided with a support structure which supports the U-shaped tube. Two openings of the U-shaped tube are equipped with an integrated sealing cover with round holes at two sides. The round holes of the sealing cover are consistent with the centers of the openings of the U-shaped tube. One end of the tray support rod with a piston is sleeved in the opening of one side of the U-shaped tube, and the other end goes through the round hole of the sealing cover and is connected to a tray. When a weighed item or weight is placed in the tray, the tray support rod slides up and down vertically in the round hole of the sealing cover, the friction phenomenon of the piston of one end of the support rod and the inner wall of the U-shaped tube caused by the inclination of the support rod is prevented, thus the precision of weighing the item is raised, and preferably the hydraulic balance can be conveniently adjusted to a horizontal state by adjusting a ground foot bolt.
Description
Technical field
The invention belongs to a kind of balance of article of weighing, particularly belong to a kind of hydraulic balance of article of weighing.
Background technology
Various balance is that people's article of weighing often use article, particularly use more extensive in laboratory, current balance weighing apparatus is mainly divided into electronic balance and mechanical balance, Chinese patent literature CN202255572U also discloses a kind of hydraulic balance, this hydraulic balance comprises pedestal, counterweight, this pedestal upper horizontal arranges a tubule, tubule two ends are communicated with a cylinder body straight up respectively, arrange a piston in cylinder body respectively, piston connects a level tray by pressure pin straight up and is used for article of weighing.The pressure pin that respectively connected piston and level tray due to two ends directly arranges and is full of in the cylinder body of water body, when placing the article that counterweight or needs are weighed in level tray, pressure pin is easy to run-off the straight, piston and inboard wall of cylinder block will rub, the precision of its article of weighing being reduced, also cannot guaranteeing that this hydraulic balance is in horizontality when weighing article in addition.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of hydraulic balance.Use this hydraulic balance not only can improve the weight precision of article of weighing when weighing the article of the weight such as many parts, but also this hydraulic balance can easily be adjusted be in horizontality when weighing article.
The technical scheme that the present invention solves the problems of the technologies described above is: a kind of hydraulic balance, comprise on base and base upper surface and look level vial instrument is set, the U-shaped pipe of vertical setting and pallet pole, the tube wall on this U-shaped pipe top has been horizontally disposed with long measure scale, it is characterized in that: described base is installed with the supporting construction that support U-shaped pipe, two mouths of pipe of this U-shaped pipe are provided with the round-meshed capping in both sides of one, the circular hole of this capping is consistent with the center of circle of the mouth of pipe of this U-shaped pipe, described pallet pole is with in one end socket of piston and the mouth of pipe of this U-shaped pipe side, the other end is connected to pallet through the circular hole of described capping.
As the preferred scheme of one, the supporting construction of described U-shaped pipe is upper end with the support column of horizontal penetrating circular hole, this U-shaped pipe through support column penetrating circular hole and with the penetrating circular hole interference fit of this support column.
As the preferred scheme of one, the nearly excircle in bottom surface of described base is provided with tapped blind hole, and this blind hole inner sleeve is then with externally threaded foot bolt.
As the preferred scheme of one, the quantity of the tapped blind hole that the nearly excircle in bottom surface of described base is arranged is 3.
As the preferred scheme of one, described pallet pole coordinates with the circular hole slip non-resistance of described capping.
Use procedure of the present invention is: utilize lower margin adjusting bolt to regulate this hydraulic balance to be in horizontality, the counterweight of the Item Weight that needs to weigh is placed in the pallet connected pallet pole when the article of the weight such as many parts of weighing, the article needing to weigh progressively are added in the pallet that another pallet pole connects, when in U-shaped pipe, the liquid of both sides is in a surface level, the weight of the article namely taken is namely consistent with the weight of counterweight; When weight one timing of the article taken, then go out the weight of taken article according to the differential conversion of the height of side liquid and opposite side in the weight of counterweight and U-shaped pipe.
The invention has the beneficial effects as follows: owing to two mouths of pipe of the U-shaped pipe at this hydraulic balance being provided with the round-meshed capping in both sides of one, and the circular hole of this capping is consistent with the center of circle of the mouth of pipe of this U-shaped pipe, owing to coordinating through the circular hole of capping the circular hole slip non-resistance of the pallet pole and capping that are connected to pallet, when in pallet place weigh article or counterweight time, pallet pole will make upper and lower vertical sliding motion in the circular hole of this capping, the phenomenon preventing pole inclination to make the piston of pole one end and U-shaped inside pipe wall occur to rub occurs, the precision of its article of weighing is improved.
Again owing to being provided with 3 tapped blind holes on the nearly excircle in the bottom surface of this hydraulic balance base, and be socketed with externally threaded foot bolt in this blind hole.Adjustably this hydraulic balance can be adjusted to horizontality by foot bolt easily.
