Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Refer to fig. 2, for the utility model discloses a low temperature liquid storage tank with liquid level display function, including jar body 1, jar body 1 is including shell 11 and install in the inside inner bag 12 of shell 11. The outer shell 11 and the inner container 12 are both cylindrical, and the lower bottom surface of the outer shell 11 is also provided with supporting legs 14 to support on the ground. And an interlayer 13 is arranged between the outer side wall of the inner container 12 and the inner side wall of the shell 11. The interlayer 13 is laid with heat insulation material to reduce the heat transfer from the outer shell 11 to the inner container 12.

The outer side wall of the inner container 12 is fixedly provided with four sliding blocks 121, and the sliding blocks 121 are uniformly distributed on the outer side wall of the inner container 12 around the center line of the inner container 12. Meanwhile, the inner side wall of the housing 11 is also concavely provided with four sliding grooves 111, and the sliding grooves 111 are uniformly distributed on the inner side wall of the housing 11 around the central line of the housing 11. And the slide groove 111 is extended in a vertical direction. That is, the sliding block 121 on the outer wall of the inner container 12 is inserted into the sliding slot 111 on the inner wall of the housing 11, and the inner container 12 is vertically displaced by the sliding of the sliding block 121 in the sliding slot 111.

In addition, a reset piece 2 is also installed between the inner container 12 and the outer shell 11, the reset piece 2 comprises two pairs of springs 21, and the springs 21 are tower-shaped springs 21. Two pairs of springs 21 are uniformly distributed at the edge of the bottom surface of the inner container 12, and one end of each spring 21 is connected to the lower bottom surface of the outer wall of the inner container 12, and the other end is connected to the lower bottom surface inside the shell 11.

When the weight of the inner container 12 changes, the inner container 12 moves up and down along the chute 111 by the action of gravity, and the compression length of the spring 21 changes with the movement of the inner container 12.

Referring to fig. 2 and 3, a horizontal indication rod 3 is further fixedly arranged on the outer side wall of the inner container 12 near the upper end, and a vertically extending accommodating groove 112 is further formed on the outer shell 11. And the indication rod 3 on the inner container 12 extends towards the housing 11 and penetrates through the containing groove 112 to penetrate out of the housing 11, so that the indication rod 3 can move up and down in the containing groove 112 along with the up and down movement of the inner container 12.

And when the low temperature liquid is added into the inner container 12, the weight of the inner container 12 is gradually increased, the inner container 12 moves the compression spring 21 downwards, and the indication rod 3 moves downwards in the containing groove 112 along with the movement of the inner container 12. When the inner container 12 is filled with the low-temperature liquid, the indicating rod 3 is located at the lowest end of the accommodating groove 112. When the low-temperature liquid in the inner container 12 is gradually discharged, the weight of the inner container 12 is gradually reduced, the inner container 12 moves upward due to the elastic force of the spring 21, and the indication rod 3 moves upward in the accommodation groove 112 along with the movement of the inner container 12. And when the low temperature liquid in the inner container 12 is completely discharged, the indicating rod 3 is positioned at the uppermost end of the containing groove 112.

Moreover, a transparent scale shell 4 is further fixed at the position of the accommodating groove 112 on the housing 11, the transparent scale shell 4 is in a square box shape, and the transparent scale box is arranged towards the opening of one side of the accommodating groove 112, namely, the open end of the transparent scale shell 4 is fixedly covered on the edge of the accommodating groove 112, so that the end of the indicating rod 3 penetrating out of the housing 11 is located in the transparent scale shell 4.

A plurality of rubber strips 41 are arranged on the inner side of the transparent scale shell 4 and the side surface far away from the accommodating groove 112, the rubber strips 41 are vertically and uniformly arranged from top to bottom, and each rubber strip 41 represents the liquid level in one inner container 12. That is, when the indicating rod 3 moves from top to bottom, the indicating rod 3 presses the rubber strip 41 at the uppermost layer to bend and deform the rubber strip 41, so that the liquid level in the inner container 12 reaches the liquid level indicated by the rubber strip 41 at the uppermost layer. The indicating rod 3 continues to move downwards to sequentially press the rubber strip 41, and then the staff can determine the height of the liquid level in the liner 12 through the change of the rubber strip 41.

In addition, a trigger switch 42, here a toggle switch, is provided within the transparent scale housing 4. An alarm 43 is mounted on the lower bottom surface of the outer side wall of the transparent scale housing 4, and the trigger switch 42 is coupled with the alarm 43. And, the trigger switch 42 is set in the lower end of the transparent scale shell 4, and when the low temperature liquid is added into the inner container 12, the inner container 12 moves down and the indication rod 3 moves down, when the liquid level of the low temperature liquid in the inner container 12 approaches the top surface of the inner container 12, the indication rod 3 touches the trigger switch 42, and the alarm 43 reminds the staff to stop the operation of filling the low temperature liquid into the inner container 12.

The top of the inner container 12 is also fixedly provided with a liquid injection pipe 15, and a telescopic opening is arranged on the shell 11 and at a position corresponding to the liquid injection pipe 15, namely the liquid injection pipe 15 extends upwards and is inserted into the telescopic opening. When the inner container 12 is empty, the liquid injection tube 15 extends out of the telescopic opening, and the low-temperature liquid can be filled into the inner container 12 through the liquid injection tube 15. When the inner container 12 is filled with low-temperature liquid, the liquid injection pipe 15 moves downwards and is accommodated in the telescopic opening. Meanwhile, a sealing cover 5 for sealing the liquid pouring tube 15 is provided on the nozzle of the liquid pouring tube 15.

The lower bottom surface of inner bag 12 is equipped with casting tube 16, and the shell 11 is gone up and the position that casting tube 16 corresponds is opened has the flexible mouth, and casting tube 16 extends downwards and inserts in the flexible mouth. And when the inner container 12 is in an empty state, the liquid discharge pipe 16 is retracted into the telescopic opening. When the inner container 12 is filled with low-temperature liquid, the liquid discharge pipe 16 extends out of the telescopic opening, and the low-temperature liquid can be discharged outwards.

The implementation principle of the embodiment is as follows:

when the low-temperature liquid needs to be added into the storage tank, the sealing cover 5 is firstly unscrewed, then the low-temperature liquid is added into the inner container 12 through the liquid injection pipe 15, and the compression spring 21 is moved downwards along with the weight of the inner container 12 when the low-temperature liquid is added. Meanwhile, the indicating rod 3 moves downwards in the chute 111 along with the movement of the inner container 12 and sequentially presses the rubber strip 41, and then the staff confirms the liquid level condition in the inner container 12 through the change of the rubber strip 41. When the liquid level of the low-temperature liquid in the inner container 12 is close to the top surface of the inner container 12, the indicating rod 3 touches the trigger switch 42 to enable the alarm 43 to remind a worker to stop filling the low-temperature liquid into the inner container 12.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
