Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of multi-mouth volumetric flasks, in particular to a multi-mouth volumetric flask for rapid collection. Background Art
[0002] A multi-mouth volumetric flask is a container used to package and store liquids or particles. It is usually used in chemical laboratories, the medical field, etc. A multi-mouth volumetric flask is composed of multiple bottle openings. Different liquids are added from different bottle openings and enter the interior of the bottle body, so that the various liquids are mixed and become the required liquid.
[0003] However, traditional multi-mouth volumetric flasks are not convenient for adjusting the speed of liquid inflow and cannot add or stop liquid in time, which will cause the mixed liquid to fail to achieve the desired effect or to achieve excessive amounts. It also requires workers to be very focused. For workers, staring at the flow of liquid for a long time will also make them very tired. Utility Model Content
[0004] In order to make up for the above shortcomings, the utility model provides a multi-mouth volumetric flask for rapid collection, aiming to improve the inconvenience of adjusting the speed at which liquid flows into the volumetric flask.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A multi-mouth volumetric flask for quick collection includes a volumetric flask, a first bottle mouth is provided on the upper surface of the volumetric flask, a bottle stopper is slidably connected to the inner wall of the first bottle mouth, a first pipe is slidably connected to the inside of the bottle stopper, a first groove is provided on the outer wall of the first pipe, a baffle is provided inside the first pipe, a first push-pull rod is fixedly connected to the outer wall of the baffle, the bottom end of the first pipe is slidably connected to the inside of the volumetric flask, a second bottle mouth is provided on the outer wall of the volumetric flask, and a third bottle mouth is provided on the outer wall of the volumetric flask.
[0007] Preferably, the outer wall of the first push-pull rod is rotatably connected to the inner wall of the first groove, and the outer wall of the baffle is slidably connected to the inner wall of the first pipe.
[0008] Preferably, a fixing block is provided below the volumetric flask, and a second groove is provided inside the fixing block.
[0009] Preferably, a sliding column is provided inside the second groove, and a spring is slidably connected to the outer wall of the sliding column.
[0010] Preferably, one end of the sliding column is fixedly connected to a first fixing rod, and an outer wall of the first fixing rod is fixedly connected to a second push-pull rod.
[0011] Preferably, a second fixing rod is fixedly connected to the upper surface of the fixing block, and a third fixing rod is fixedly connected to the upper surface of the second fixing rod.
[0012] Preferably, a semi-ring is fixedly connected to the outer wall of the third fixing rod, and the outer wall of the semi-ring is slidably connected to the outer wall of the volumetric flask.
[0013] Preferably, the outer wall of the second fixing rod is slidably connected to the inner wall of the second groove, one end of the spring is fixedly connected to one end of the sliding column, and the other end of the spring is fixedly connected to the inner wall of the second groove.
[0014] The utility model has the following beneficial effects:
[0015] 1. In the utility model, a bottle stopper is pressed into the first pipe to prevent the loss of liquid. When liquid is added, the push-pull rod is twisted to rotate the push-pull rod, thereby driving the rotation of the baffle. When a small amount of liquid needs to be added, the push-pull rod is twisted in the opposite direction to allow the liquid to drip into the bottle drop by drop. This device can arbitrarily control the speed at which the liquid flows into the volumetric flask.
[0016] 2. In the present invention, the second push-pull rod is pulled outward, driving the third fixed column to move outward, thereby driving the semi-ring to move outward. When the second push-pull rod is released, the rebound of the spring causes the semi-ring to fit against the outer wall of the volumetric flask, thereby clamping the volumetric flask.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Reference Figure 1-3 The utility model provides an embodiment of a multi-mouth volumetric flask for rapid collection, comprising a volumetric flask 1, a first bottle opening 2 being provided on the upper surface of the volumetric flask 1, a bottle stopper 7 being slidably connected to the inner wall of the first bottle opening 2, a first pipe 3 being slidably connected to the inside of the bottle stopper 7, a first groove 4 being provided on the outer wall of the first pipe 3, a baffle 5 being provided inside the first pipe 3, a first push-pull rod 6 being fixedly connected to the outer wall of the baffle 5, a bottom end of the first pipe 3 being slidably connected to the inside of the volumetric flask 1, a second bottle opening 17 being provided on the outer wall of the volumetric flask 1, and a third bottle opening 18 being provided on the outer wall of the volumetric flask 1; the outer wall of the first push-pull rod 6 is rotatably connected to the inner wall of the first groove 4, and the outer wall of the baffle 5 is slidably connected to the inner wall of the first pipe 3;
[0024] Specifically, the stopper 7 is pressed into the first bottle mouth 2, and liquid is added through the first pipe 3 inside the stopper 7, and flows into the volumetric flask 1. When the required liquid is about to reach the appropriate position, the first push-pull rod 6 in the first groove 4 is twisted, and the first push-pull rod 6 drives the baffle 5 to rotate, thereby reducing the inflow space in the first pipe 3 and reducing the speed of the inflowing liquid, thereby achieving the effect of conveniently adjusting the speed of the liquid flowing into the volumetric flask 1.
[0025] A fixed block 8 is provided below the volumetric flask 1, and a second groove 9 is provided inside the fixed block 8; a sliding column 10 is provided inside the second groove 9, and a spring 11 is slidably connected to the outer wall of the sliding column 10; one end of the sliding column 10 is fixedly connected to a first fixed rod 12, and the outer wall of the first fixed rod 12 is fixedly connected to a second push-pull rod 13; a second fixed rod 14 is fixedly connected to the upper surface of the fixed block 8, and the upper surface of the second fixed rod 14 is fixedly connected to a third fixed rod 15; the outer wall of the third fixed rod 15 is fixedly connected to a semi-ring 16, and the outer wall of the semi-ring 16 is slidably connected to the outer wall of the volumetric flask 1; the outer wall of the second fixed rod 14 is slidably connected to the inner wall of the second groove 9, one end of the spring 11 is fixedly connected to one end of the sliding column 10, and the other end of the spring 11 is fixedly connected to the inner wall of the second groove 9;
[0026] Specifically, pull the second push-pull rod 13 outward, the second push-pull rod 13 drives the sliding column 10 to move, thereby driving the spring 11 to move, the movement of the sliding column 10 drives the second fixed rod 14 to slide in the second groove 9, thereby driving the third fixed rod 15 to move outward, and the movement of the third fixed rod 15 drives the semi-ring 16 to move, and the volumetric flask 1 is placed above the fixed block 8. Slowly release the second push-pull rod 13, and the rebound of the spring 11 drives the semi-ring 16 to rebound, thereby clamping the volumetric flask 1, which makes it convenient to clamp the volumetric flask 1 and adjust it according to the size of the volumetric flask 1.
[0027] Working principle: When the volumetric flask 1 needs to be used, the second push-pull rod 13 outside the fixed block 8 is pulled outward, and the second push-pull rod 13 drives the first fixed rod 12 and the sliding column 10 to move, thereby driving the spring 11 to move. The movement of the sliding column 10 drives the second fixed rod 14 to slide in the second groove 9, thereby driving the third fixed rod 15 to move outward, and the movement of the third fixed rod 15 drives the semi-ring 16 to move. The volumetric flask 1 is placed above the fixed block 8, and the second push-pull rod 13 is slowly released. The rebound of the spring 11 drives the semi-ring 16 to rebound as well, thereby clamping the volumetric flask 1, which makes it convenient to clamp the volumetric flask 1 and adjust it according to the size of the volumetric flask 1. The stopper 7 is pressed into the first bottle mouth. 2. The inner walls of the second bottle mouth 17 and the third bottle mouth 18 are sealed and protected, and liquid is added through the first pipe 3 to flow into the interior of the bottle body. When the added liquid is about to reach the required amount, the first push-pull rod 6 in the first groove 4 is twisted, and the first push-pull rod 6 drives the baffle 5 to rotate, thereby narrowing the inflow space inside the first pipe 3 and reducing the amount of liquid flowing in. When the adding is completed, the first push-pull rod 6 is twisted to make the outer wall of the baffle 5 completely fit the inner wall of the first pipe 3, so that the liquid no longer flows into the volumetric flask 1, which makes it convenient to adjust the speed of adding liquid. The volumetric flask 1 can achieve the effect of conveniently adjusting the speed of liquid inflow, and can also achieve the effect of adjusting the clamping according to the size of different volumetric flasks 1.
