Description

Technical Field

[0001] The utility model relates to the field of environmental monitoring sampling tools, in particular to an environmental detection liquid sample temporary storage device. Background Art

[0002] In environmental testing, liquid sampling is very common, such as water, sewage, waste liquid, etc., which need to be taken to the laboratory for testing. At present, sampling generally uses sample bottles to hold samples. Some sample bottles are stoppered glass bottles. Because glass has stable chemical properties, it is used to hold some potentially corrosive liquid samples. In the process of carrying and transporting samples, the bottle stopper is easy to loosen, resulting in sample leakage;

[0003] When sampling is required at multiple locations, labels need to be affixed to the bottles to avoid sample confusion, and the labels on the bottles need to be replaced repeatedly when sampling is performed multiple times.

[0004] There are existing sample storage boxes, such as application number: CN202222647219.3, title: A utility model patent for a sample box for water quality environment testing, in which a slot is provided in the sample box for placing sample bottles to prevent the sample bottles from being messy and colliding, and then the bottle caps are fixed by a pressing plate. This pressing plate is prone to the situation that individual bottle plugs are not completely pressed, and the samples are prone to leakage;

[0005] In addition, most of the existing storage boxes are of a flip-top structure. When taking or placing samples, it is necessary to open the lid and search inside the box, which is rather troublesome. During this process, if the box falls or is accidentally knocked over, all samples are at risk of being lost. Moreover, even if the box structure is not opened, the lid is very easy to open in the event of a fall or collision, causing the samples to be scattered and damaged. Summary of the invention

[0006] In order to solve the problems of easy leakage of sample bottles during transportation, the need for labeling to avoid confusion, and poor safety of sample boxes, the utility model provides a temporary storage device for environmental testing liquid samples.

[0007] The technical solution includes a sample box and a sample bottle consisting of a bottle body and a bottle stopper. The sample box is a cylindrical shell. A disc-shaped rotating body is coaxially installed in the sample box. A plurality of vertical receiving grooves are provided on the upper surface of the rotating body. The plurality of receiving grooves are arranged along the circumference of the rotating body. The sample bottle can be placed in the receiving groove. A taking and placing opening is provided on the upper end surface of the sample box. When the rotating body rotates around the axis in the sample box, the plurality of receiving grooves can pass under the taking and placing opening in sequence. A compression spring is installed at the bottom of each receiving groove. When the sample bottle is placed in the receiving groove, the bottle stopper of the sample bottle presses against the upper end surface of the sample box under the action of the compression spring.

[0008] A first gear is installed on the core shaft of the rotating body, and a driving motor is installed at the bottom of the sample box. The driving motor is connected to a second gear, and the second gear is meshed with the first gear; a plurality of button switches and a zero position switch are provided on the upper end surface of the sample box. When the zero position switch is pressed, the driving motor returns to the zero position. At this time, all the accommodating grooves are not aligned with the access port. The number of button switches is the same as the number of accommodating grooves and corresponds one to one. Each button switch corresponds to a rotation angle of the driving motor. When a button switch is pressed, the accommodating groove corresponding to the button switch rotates to below the access port.

[0009] An arc-shaped pressing plate is installed on one side of the access opening. After the sample bottle is placed into the containing groove from the access opening, the arc-shaped pressing plate will gradually press down the sample bottle as the rotating body rotates, so that the sample bottle completely enters the sample box.

[0010] The upper end surface of the sample box is a split cover plate, which is fixedly connected to the box body via screws.

[0011] A plurality of first balls are evenly distributed on the circumference of the bottom of the sample box, and the first balls are supported below the rotating body.

[0012] The upper end of the bottle stopper of the sample bottle is provided with a second rolling ball.

[0013] The diameters of any two sample bottles are different, and the diameters of any two containing grooves are also different. The diameters of the sample bottles and the diameters of the containing grooves are in a one-to-one matching relationship.

[0014] The utility model does not cause leakage of samples during carrying and transportation, does not require sample marking on the bottle body, is convenient for taking and placing samples, and has high safety of the sample box. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Combination Figures 1 to 4The utility model comprises a sample box 1 and a sample bottle 2 consisting of a bottle body and a bottle stopper, a sealing ring is installed on the bottle stopper, the sample box 1 is a cylindrical shell, both ends of the shell have end faces, a disc-shaped rotating body 3 is coaxially installed in the sample box 1, a core shaft is provided at the axis of the rotating body 3, both ends of the core shaft are installed on the upper and lower end faces of the shell through bearings, a plurality of vertical accommodating grooves 4 are opened on the upper surface of the rotating body 3, and the plurality of accommodating grooves 4 are arranged along the circumference of the rotating body 3, and the sample bottle 2 can be placed in the accommodating grooves, The upper end surface of the sample box 1 is provided with a take-in / put-out opening 5. When the rotating body 3 rotates around the axis in the sample box 1, a plurality of accommodating grooves 4 can pass under the take-in / put-out opening 5 in sequence. At this time, the sample bottle 2 can be put into the accommodating groove 4 or taken out from the accommodating groove 4. A compression spring 6 is installed at the bottom of each accommodating groove 4. When the sample bottle 2 is placed in the accommodating groove 4, under the action of the compression spring 6, the bottle stopper of the sample bottle 2 presses against the upper end surface of the sample box 1, so that the bottle stopper is pressed tightly in the bottle mouth of the bottle body, so that the bottle stopper will not loosen or fall off.

[0020] A first gear 7 is installed on the spindle of the rotating body 3, and a driving motor 8 is installed at the bottom of the sample box 1. The driving motor 8 is connected to a second gear 9, which is meshed with the first gear 7. The driving motor 8 drives the rotating body 3 to rotate through a reduction gear set composed of the first gear 7 and the second gear 9; a plurality of button switches 10 and a zero position switch 11 are provided on the upper end surface of the sample box 1. When the zero position switch 11 is pressed, the driving motor 8 returns to the zero position. At this time, all the accommodating grooves 4 are not aligned with the access opening 5. The number of button switches 10 is the same as the number of accommodating grooves 4 and corresponds one to one. Each button switch 10 corresponds to a rotation angle of the driving motor 8. When a button switch 10 is pressed, the accommodating groove 4 corresponding to the button switch 10 rotates to the bottom of the access opening 5. Each button switch 10 has a fixed number, which means that each accommodating groove 4 and the sample bottle 2 therein and the sample in the bottle are numbered, so there is no need to attach a label to the bottle.

[0021] An arc-shaped pressing plate 12 is installed on one side of the access opening 5. After the sample bottle 2 is placed into the accommodating groove 4 from the access opening 5, as the rotating body 3 rotates, the arc-shaped pressing plate 12 will gradually press the sample bottle 2 downward, so that the sample bottle 2 completely enters the sample box 1, and the compression spring 6 is in a compressed state.

[0022] The upper end surface of the sample box 1 is a split cover plate 13 , which is fixedly connected to the box body via screws, so as to facilitate installation of the rotating body 3 in the sample box 1 .

[0023] A plurality of first balls 14 are evenly distributed on the circumference of the bottom of the sample box 1 , and the first balls 14 are supported below the rotating body 3 to ensure that the rotating body 3 does not deflect.

[0024] The upper end of the bottle stopper of the sample bottle 2 is provided with a second ball 15 , and the second ball 15 can reduce the resistance of the sample bottle 2 when it rotates with the rotating body 3 .

[0025] The diameters of any two sample bottles 2 are different, and the diameters of any two receiving grooves 4 are also different. The diameter of the sample bottle 2 and the diameter of the receiving groove 4 are in a one-to-one matching relationship. For example, the diameter of the receiving groove 4 and the diameter of the sample bottle 2 both increase or decrease in the order of the labels. This is to avoid confusion when taking out multiple sample bottles 2 at the same time.

[0026] When the sample bottle 2 is not taken in or put in, the rotating body 3 is in the zero position state, and any accommodating groove 4 is not aligned with the taking-in and putting-out opening 5. After the sample bottle 2 is loaded with the sample, the button switch 10 corresponding to the sample bottle 2 is pressed. For example, if the sample bottle 2 is the No. 3 sample bottle 2, the No. 3 button switch 10 is pressed, and the driving motor 8 drives the rotating body 3 to rotate until the No. 3 accommodating groove 4 is aligned with the taking-in and putting-out opening 5. At this time, the sample bottle 2 is put into the accommodating groove 4, and then the zero position switch 11 is pressed, and the rotating body 3 rotates back to the zero position; in the process of the rotating body 3 rotating back to the zero position, the arc-shaped pressing plate 12 will steadily press down the newly put in sample bottle 2, and the compression spring 6 under the sample bottle 2 is compressed. After the sample bottle 2 is completely put into the sample box 1, under the action of the compression spring 6, the bottle stopper presses the cover plate 13, so that the bottle stopper will not loosen or fall off during the transportation process. No matter what state the sample box 1 is in, the sample in the sample bottle 2 will not leak.

[0027] Similarly, when it is necessary to take a sample, just press the corresponding button switch 10. For example, press the No. 3 button switch 10, and the rotating body 3 rotates until the No. 3 receiving groove 4 is aligned with the access opening 5, and the sample bottle 2 pops up. At this time, the No. 3 sample bottle 2 can be taken out. After taking out the sample bottle 2, press the zero position switch 11 again to return the rotating body 3 to the zero position.

[0028] After 10 seconds of no operation, the rotor 3 will automatically return to the zero position.

[0029] The stopper of the sample bottle 2 of the utility model is in a compressed state in the sampling box, and the sample will not leak during the carrying and transportation process. The sample bottle 2 is completely fixed and isolated, and will not collide with each other.

[0030] In addition, the accommodating grooves 4 are matched one by one with the sample bottles 2, and there is no need to mark the samples on the bottle bodies. The sample bottles 2 have different bottle diameters, and confusion will not occur even when multiple sample bottles 2 are taken out at the same time.

[0031] The utility model is easy to use, and when taking and placing samples, only a switch needs to be pressed; moreover, the utility model has a closed structure and adopts a rotating taking and placing method, so that even if it falls or collides, the sample box 1 will not be opened to cause sample loss.
