Description

Portable acidimeter

Technical Field

The utility model belongs to the technical field of acidimeters, and particularly discloses a portable acidimeter.

Background

The PH meter, which is an acidimeter, is an instrument for measuring the PH value of a solution and operates on the principle of a galvanic cell. The electromotive force between the two electrodes of a galvanic cell depends, according to nernst's law, both on the properties of the electrodes themselves and on the hydrogen ion concentration in the solution. There is a corresponding relationship between the electromotive force of the primary cell and the hydrogen ion concentration, and the negative logarithm of the hydrogen ion concentration is the pH value. The acidimeter is widely applied to the fields of agriculture, environmental protection, industry and the like.

The existing small-sized hand-held acidimeter has small volume, is convenient to use, and can be placed in a working box and cannot be placed at will when not in use. When the acidity is required to be frequently detected or the acidity is detected in a clearance mode, the acidity meter is usually held by hands, and if the acidity meter needs to be matched with other things in the process, the process is very inconvenient. In addition, the handheld acidimeter is held in the hand for a long time, the falling probability is high, and the handheld acidimeter is easy to break after falling.

Disclosure of Invention

The utility model aims to provide a portable acidimeter, which solves the problems that the acidimeter is inconvenient to carry and easy to break in the using process.

In order to achieve the purpose, the basic scheme of the utility model is as follows: the portable acidimeter comprises an acidimeter body and a clamping piece, wherein the back of the acidimeter body is provided with a through hole, and a cavity communicated with the through hole is arranged in the acidimeter body; one end of the clamping piece is provided with a connecting block extending into the cavity, the other end of the clamping piece is embedded with a magnet, the acidimeter body is provided with an electromagnet corresponding to the magnet, a switch for controlling the on-off state of the electromagnet is arranged in the cavity, and the switch can be opened by the connecting block under the action of gravity of the acidimeter body; the four corners of the acidimeter body are wrapped with anti-collision protrusions.

The working principle of the basic scheme is as follows: this acidimeter can hand normal use when using, if need last the use after using, can go deep into coat-sleeve, pocket or other openings part with the clamping piece, let out the acidimeter body. The acidimeter body can drop down under its self action of gravity after releasing, and the switch is opened to the connecting block under the action of gravity, and the electro-magnet circular telegram is inhaled with magnet mutually to make this acidimeter pass through the fixed centre gripping of clamping piece at openings such as coat-sleeve, pocket. If need use this acidimeter, can take this acidimeter, the action of gravity of acidimeter body disappears, and the switch will be closed to the connecting block, and then makes the electro-magnet outage, and the effort of electro-magnet and magnet disappears, then can make this acidity conveniently take hold. If this acidimeter drops on the ground in the use, the crashproof arch on the acidimeter body can effectively cushion the striking effect, and then protects this acidimeter, prevents that this acidimeter from breaking.

The beneficial effect of this basic scheme lies in:

1. through the action of gravity of acidimeter body self in this scheme, can be with the fixed centre gripping of this acidimeter at arbitrary opening part, even decurrent opening part, for example collarband, cuff, pocket edge and lower edge opening etc. of clothes, this just makes this acidimeter conveniently carry in the use, can be fixed with it fast in needs clearance nature use.

2. Through the anticollision arch in this scheme, can prevent that this acidimeter from being broken after dropping, and then make this acidimeter life longer.

Compared with the prior art, the acidimeter can be fixed the centre gripping acidimeter at any time, need not hold the acidimeter always, very conveniently carries, and the gravity action control of fixed centre gripping process through the acidimeter body, and easy operation is convenient.

Further, the switch is a press switch, the connecting block comprises a connecting column and a press block, the press block is located in the cavity, and the connecting column is in sliding connection with the through hole.

The switch is pressed to be convenient for the connecting block to the control of switch, and the spliced pole is more reasonable with this acidimeter structural design of being convenient for according to setting up of pressing the piece.

Furthermore, the cross section of the cavity is in a circular truncated cone shape, one end with a small diameter of the cavity is connected with the through hole, and the press switch is arranged on the side wall of the cavity.

This structure facilitates the setting of the push switch.

Furthermore, the pressing block is in a shape of a truncated cone with the volume equal proportion smaller than that of the cavity, and an elastic piece is arranged between the bottom of the cavity and the pressing block.

Make press the effect to press the switch that the briquetting can be better, the elastic component then is convenient for press the briquetting and lose the gravity action of acidimeter body after kick-backing to relieve press the switch.

Further, the elastic part is a spring, and a sealing ring which hermetically slides with the connecting column is arranged on the inner wall of the through hole.

The structure in the cavity is protected conveniently, and damage in use is prevented.

Further, the end of the clamping piece provided with the magnet is tilted towards the direction far away from the acidimeter body.

The clamping piece is convenient to be clamped at the opening of the collar, the cuff and the like.

Further, the outside of the anti-collision bulge is arc-shaped, and a balancing weight is arranged inside the anti-collision bulge.

Make the acidimeter in this scheme more pleasing to the eye, the acidimeter in this scheme of protection that also can be better simultaneously.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the acidimeter body 10, through-hole 11, cavity 12, clamping piece 20, spliced pole 21, pressing block 22, sealing washer 23, elastic component 24, magnet 30, electro-magnet 31, switch 32, anticollision arch 40, balancing weight 41.

As shown in fig. 1 and 2, the portable acidimeter comprises an acidimeter body 10 and a clamping piece 20, wherein a through hole 11 is formed in the back of the acidimeter body 10, and a cavity 12 communicated with the through hole 11 is formed in the acidimeter body 10; the cross section of the cavity 12 is in a round table shape, and one end of the cavity 12 with a small diameter is connected with the through hole 11.

The upper end of the clamping piece 20 is provided with a connecting block extending into the cavity 12, and the lower end of the clamping piece 20 tilts towards the direction far away from the acidimeter body 10. The connecting block comprises a connecting column 21 and a pressing block 22, the pressing block 22 is positioned in the cavity 12, and the connecting column 21 is positioned between the clamping piece 20 and the pressing block 22; the connecting column 21 is connected with the through hole 11 in a sliding way, and the inner wall of the through hole 11 is provided with a sealing ring 23 which slides with the connecting column 21 in a sealing way. The pressing block 22 is a truncated cone with the volume equal proportion smaller than that of the cavity 12, an elastic piece 24 is arranged between the bottom of the cavity 12 and the pressing block 22, and the elastic piece 24 is preferably a spring in the embodiment.

The lower end of the clamping piece 20 is embedded with a magnet 30, the acidimeter body 10 is provided with an electromagnet 31 corresponding to the magnet 30, the cavity 12 is internally provided with a switch 32 for controlling the electromagnet 31 to be powered on and powered off, and the switch 32 can be opened by the connecting block under the action of gravity of the acidimeter body 10.
