Description

Technical Field

[0001] The utility model relates to the technical field of sampling bottles, in particular to a self-sealing sampling bottle. Background Art

[0002] A sampling bottle is a container that is usually used to collect and analyze substances in samples. It can store and transport samples and help researchers determine the composition and properties of samples, protect samples from external contamination and damage, thereby ensuring the accuracy and reliability of experimental results. It is widely used in scientific experiments, medical testing, food safety and other fields.

[0003] The existing technology requires that the bottle cap be removed and the sample be poured out directly through a sampling device or directly. Although sampling can be performed, the staff's attention is focused on the sample after sampling. If the staff is busy with the experiment and forgets to cover the bottle cap, the sample will be exposed to the air for a long time, causing impurities in the air to eventually affect the sample in the sampling bottle, and ultimately affect the test results when sampling is repeated later. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a self-sealed sampling bottle, which can prevent impurities in the air from affecting the sample in the sampling bottle and avoiding affecting the detection result.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A self-sealed sampling bottle comprises a bottle body, a bottle mouth which can be connected to the inside of the bottle body is fixedly connected to the top of the bottle body, and a first elastic sheet and a second elastic sheet which are arranged opposite to each other are fixedly connected to the inner wall of the bottle mouth; the first elastic sheet and the second elastic sheet are both arc-shaped, a second clamping block is fixedly connected to the side of the first elastic sheet close to the second elastic sheet, and a first clamping block is fixedly connected to the side of the second elastic sheet close to the first elastic sheet, and the first clamping block and the second clamping block are engaged with each other; a cover plate which is adapted to the bottle mouth is rotatably connected to the side of the top of the bottle mouth close to the second elastic sheet;

[0007] A funnel-shaped groove is provided on the top of the cover plate, the bottom of the groove passes through the cover plate, an injection tube connected to the groove is fixedly connected to the bottom of the cover plate, and a protective cover adapted to the cover plate is rotatably connected to one side of the top of the cover plate.

[0008] A protective pad for enhancing sealing is fixedly connected to one side of the protective cover close to the cover plate.

[0009] A plurality of magnetic strips are fixedly connected to the inside of the protective pad and to a side of the cover plate close to the protective cover, and the positions of the magnetic strips on the protective pad correspond to those of the magnetic strips on the cover plate.

[0010] The outer surface of the second elastic piece is fixedly connected with a fixing block above the first clamping block, and the fixing block is arranged obliquely.

[0011] The outer surface of the bottle body is covered with a protective cover for protecting the bottle body, and the protective cover is provided with a plurality of observation windows for observing the interior of the bottle body.

[0012] The bottom of the protective sleeve is fixedly connected with a protective base for maintaining the stability of the bottle body.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model is provided with a first spring sheet, a second spring sheet, a first clamping block and a second clamping block. When sampling is needed, the cover plate is rotated to extend a sampling device such as a dropper from the bottle mouth. When the first clamping block or the second clamping block is touched, the first spring sheet and the second spring sheet are pressed toward the inner wall of the bottle mouth by the extrusion force, driving the first clamping block and the second clamping block to move away from each other and no longer clamping each other. At this time, the sampling device can be extended from the bottle mouth to the inside of the bottle body, so as to perform sampling. When the sampling is completed, the sampling device is taken out, the first spring sheet and the second spring sheet are no longer subjected to force, and begin to rebound and reset, driving the first clamping block and the second clamping block to clamp again, and the bottle body is re-sealed. The advantage of this is that after the sampling device is taken out, the first clamping block and the second clamping block are automatically clamped under the influence of the first spring sheet and the second spring sheet, so that the bottle body can be sealed by itself when not in operation, effectively solving the problem that the staff forgets to cover the bottle cap after sampling and causes the sample to be exposed to the air for a long time due to being busy with experiments, and preventing impurities in the air from affecting the sample in the sampling bottle and affecting the test result when sampling is performed again.

[0015] The utility model arranges a cover plate and an injection tube. When the cover plate is fitted and closed with the bottle mouth, the injection tube squeezes the first clamping block and the second clamping block, so that the first spring sheet and the second spring sheet are close to the inner wall of the bottle mouth, allowing the injection tube to extend into the interior of the bottle body. When the sample needs to be stored in the bottle body, the protective cover on the cover plate is rotated to force the magnetic strip on the protective pad to separate from the magnetic strip on the cover plate, and then the sample is poured on the top of the cover plate, allowing the sample to enter the interior of the injection tube through the funnel-shaped groove and finally flow into the interior of the bottle body. The protective cover is then closed to complete the storage of the sample. The advantage of this is that the sample can be smoothly stored in the bottle body while ensuring that the sample can be taken, and the staff can still focus on the bottle body after storing the sample in the bottle body, and can close the protective cover again to ensure the sealing of the bottle body.

[0016] The utility model arranges a fixing block so that when the cover plate closes the bottle mouth, the injection tube contacts the fixing block first, and squeezes the fixing block so that the second spring piece is pressed toward the inner wall of the bottle mouth, so that the first clamping block is separated from the second clamping block first, so that the injection tube can be inserted into the interior of the bottle body more smoothly. By arranging a protective sleeve and a protective base, the bottle body can be placed more easily, and a buffering and protective effect is played to prevent the bottle body from being damaged by external forces.

[0023] The following is a detailed description of a self-sealing sampling bottle provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0024] like Figure 1-Figure 4 As shown, the embodiment of the utility model provides a self-sealed sampling bottle, comprising a bottle body 1, a bottle mouth 2 which can be connected to the inside of the bottle body 1 is fixedly connected to the top of the bottle body 1, a first elastic sheet 4 and a second elastic sheet 5 which are arranged opposite to each other are fixedly connected to the inner wall of the bottle mouth 2, the first elastic sheet 4 and the second elastic sheet 5 are both arc-shaped, a second clamping block 7 is fixedly connected to the side of the first elastic sheet 4 close to the second elastic sheet 5, a first clamping block 6 is fixedly connected to the side of the second elastic sheet 5 close to the first elastic sheet 4, and the first clamping block 6 and the second clamping block 7 are engaged with each other; a cover plate 3 which is adapted to the bottle mouth 2 is rotatably connected to the side of the top of the bottle mouth 2 close to the second elastic sheet 5;

[0025] A funnel-shaped groove 9 is provided on the top of the cover plate 3, and the bottom of the groove 9 passes through the cover plate 3. An injection tube 8 connected to the groove 9 is fixedly connected to the bottom of the cover plate 3. A protective cover 10 adapted to the cover plate 3 is rotatably connected to one side of the top of the cover plate 3. A protective pad 11 for enhancing the sealing is fixedly connected to the side of the protective cover 10 close to the cover plate 3. A plurality of magnetic strips 12 are fixedly connected to the inside of the protective pad 11 and the side of the cover plate 3 close to the protective cover 10. The positions of the magnetic strips 12 on the protective pad 11 correspond to those of the magnetic strips 12 on the cover plate 3.

[0026] By providing the first spring piece 4, the second spring piece 5, the first clamping block 6 and the second clamping block 7, when sampling is required, the cover plate 3 is rotated, and a sampling device such as a dropper is inserted from the bottle mouth 2. When the first clamping block 6 or the second clamping block 7 is touched, the first spring piece 4 and the second spring piece 5 are squeezed and moved toward the inner wall of the bottle mouth 2, driving the first clamping block 6 and the second clamping block 7 to move away from each other and no longer clamped to each other. At this time, the sampling device can be inserted from the bottle mouth 2 into the interior of the bottle body 1, so as to perform sampling;

[0027] When sampling is completed, the sampling device is taken out, and the first spring piece 4 and the second spring piece 5 are no longer subjected to force and begin to rebound and reset, driving the first clamping block 6 and the second clamping block 7 to re-engage, and the bottle body 1 is re-sealed. The advantage of this is that after the sampling device is taken out, the first clamping block 6 and the second clamping block 7 are automatically engaged under the influence of the first spring piece 4 and the second spring piece 5, so that the bottle body 1 can be sealed by itself when not in operation, which effectively solves the problem that the staff forgets to cover the bottle cap after sampling because they are busy with experiments, resulting in the sample being exposed to the air for a long time, and prevents impurities in the air from affecting the sample in the sampling bottle and affecting the test results when sampling and testing are performed again.

[0028] By setting the cover plate 3 and the injection tube 8, when the cover plate 3 is fitted and closed with the bottle mouth 2, the injection tube 8 squeezes the first clamping block 6 and the second clamping block 7, so that the first spring piece 4 and the second spring piece 5 are close to the inner wall of the bottle mouth 2, allowing the injection tube 8 to extend into the interior of the bottle body 1. When the sample needs to be stored in the bottle body 1, the protective cover 10 on the cover plate 3 is rotated to force the magnetic strip 12 on the protective pad 11 to separate from the magnetic strip 12 on the cover plate 3, and then the sample is poured on the top of the cover plate 3, allowing the sample to enter the interior of the injection tube 8 through the funnel-shaped groove 9, and finally flow into the interior of the bottle body 1, and then the protective cover 10 is closed to complete the storage of the sample. The advantage of this is that while ensuring that sampling can be performed, the sample can also be smoothly stored in the bottle body 1, and the staff's attention is still on the bottle body 1 after storing the sample in the bottle body 1, and the protective cover 10 can be closed and sealed again to ensure the sealing of the bottle body 1.

[0029] like Figure 1 , Figure 2 and Figure 4As shown, the outer surface of the second spring piece 5 is fixedly connected to a fixing block 13 above the first clamping block 6, and the fixing block 13 is arranged at an angle. The outer surface of the bottle body 1 is provided with a protective cover 14 for protecting the bottle body 1, and the protective cover 14 is provided with a plurality of observation windows 15 for observing the interior of the bottle body 1. The bottom of the protective cover 14 is fixedly connected to a protective base 16 for maintaining the stability of the bottle body 1.

[0030] By setting the fixing block 13, when the cover plate 3 closes the bottle mouth 2, the injection tube 8 first contacts the fixing block 13, and squeezes the fixing block 13 so that the second spring piece 5 is squeezed and approaches the inner wall of the bottle mouth 2, so that the first clamping block 6 is separated from the second clamping block 7 first, so that the injection tube 8 can be more smoothly extended into the interior of the bottle body 1. By setting the protective sleeve 14 and the protective base 16, the bottle body 1 can be placed more easily, and it plays a buffering and protective role to prevent the bottle body 1 from being damaged by external forces.

[0031] The technical solution provided by the utility model is to set the first spring piece 4, the second spring piece 5, the first clamping block 6 and the second clamping block 7. When sampling is needed, the cover plate 3 is rotated to extend the sampling device such as a dropper from the bottle mouth 2. When the first clamping block 6 or the second clamping block 7 is touched, the first spring piece 4 and the second spring piece 5 are squeezed to the inner wall of the bottle mouth 2, driving the first clamping block 6 and the second clamping block 7 to move away from each other and no longer engage with each other. At this time, the sampling device can be extended from the bottle mouth 2 to the inside of the bottle body 1, so as to perform sampling. When the sampling is completed, the sampling device is taken out. The first spring piece 4 and the second spring piece 5 are no longer subjected to force and begin to rebound and reset, driving the first clamping block 6 and the second clamping block 7 to re-engage and reseal the bottle body 1. The advantage of this is that after the sampling device is taken out, the first clamping block 6 and the second clamping block 7 are automatically engaged under the influence of the first spring piece 4 and the second spring piece 5, so that the bottle body 1 can be sealed by itself when not in operation, which effectively solves the problem that the staff forgets to cover the bottle cap after sampling because they are busy with experiments, resulting in the sample being exposed to the air for a long time, and prevents impurities in the air from affecting the sample in the sampling bottle and affecting the test results when sampling and testing are performed again.

[0032] By setting the cover plate 3 and the injection tube 8, when the cover plate 3 is fitted and closed with the bottle mouth 2, the injection tube 8 squeezes the first clamping block 6 and the second clamping block 7, so that the first spring piece 4 and the second spring piece 5 are close to the inner wall of the bottle mouth 2, allowing the injection tube 8 to extend into the interior of the bottle body 1. When the sample needs to be stored in the bottle body 1, the protective cover 10 on the cover plate 3 is rotated to force the magnetic strip 12 on the protective pad 11 to separate from the magnetic strip 12 on the cover plate 3, and then the sample is poured on the top of the cover plate 3, allowing the sample to enter the interior of the injection tube 8 through the funnel-shaped groove 9, and finally flow into the interior of the bottle body 1, and then the protective cover 10 is closed to complete the storage of the sample. The advantage of this is that while ensuring that sampling can be performed, the sample can also be smoothly stored in the bottle body 1, and the staff's attention is still on the bottle body 1 after storing the sample in the bottle body 1, and the protective cover 10 can be closed and sealed again to ensure the sealing of the bottle body 1.

[0033] By setting the fixing block 13, when the cover plate 3 closes the bottle mouth 2, the injection tube 8 first contacts the fixing block 13, and squeezes the fixing block 13 so that the second spring piece 5 is squeezed and approaches the inner wall of the bottle mouth 2, so that the first clamping block 6 is separated from the second clamping block 7 first, so that the injection tube 8 can be more smoothly extended into the interior of the bottle body 1. By setting the protective sleeve 14 and the protective base 16, the bottle body 1 can be placed more easily, and it plays a buffering and protective role to prevent the bottle body 1 from being damaged by external forces.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
