[0004] To address the issue of existing equipment failing to maintain a constant temperature and seal for metering, which is problematic because some special liquids require a constant temperature and seal for accurate measurement, otherwise differences in liquid density would reduce measurement accuracy, the existing equipment needs improvement. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel liquid metering device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A novel liquid metering device includes a metering bracket, a base, a top plate, a display screen, a button, a support rod, a metering container, and a sealing device. The base is fixedly connected to the surface of the metering bracket, the top plate is fixedly connected to the surface of the metering bracket, the display screen is fixedly connected to the surface of the metering bracket, the button is fixedly connected to the surface of the metering bracket, the support rod is fixedly connected to the surface of the top plate, the metering container is fixedly connected to the surface of the support rod, and the sealing device is fixedly connected to the surface of the metering container. The sealing device includes a stirring rod, which is fixedly connected to the surface of the top plate, and a constant temperature stirring rod is fixedly connected to the surface of the stirring rod.

[0007] Furthermore, the thermostatic stirring rod is fitted and connected to the inner wall of the metering barrel, a fixing column is fixedly connected to the surface of the metering barrel, a water inlet hole is fixedly connected to the surface of the fixing column, and a sliding plug rod is sleeved and connected to the inner wall of the fixing column.

[0008] Furthermore, a rubber stopper is fixedly connected to the surface of the sliding rod, a connecting plate is fixedly connected to the end of the sliding rod away from the rubber stopper, and a fixing groove is fixedly connected to the surface of the measuring barrel.

[0009] Furthermore, a threaded rod is inserted and connected to the inner wall of the fixing groove, a limit ring is fixedly connected to the surface of the threaded rod, a threaded groove is opened on the surface of the connecting plate, the threaded rod is threaded to the inner wall of the threaded groove, and a rotating wheel is fixedly connected to the surface of the threaded rod.

[0010] Furthermore, a draining device is fixedly connected to the surface of the metering barrel. The draining device includes a stabilizing column, which is fixedly connected to the surface of the metering barrel, and a drain hole is fixedly connected to the surface of the stabilizing column.

[0011] Furthermore, the inner wall of the stabilizing column is provided with a sliding groove, and a sliding ring 1 is fitted into the inner wall of the sliding groove. A spring is fixedly connected to the surface of the sliding ring 1, and a sliding ring 2 is fixedly connected to the end of the spring away from the sliding ring 1. A fixing collar is fixedly connected to the surface of the sliding ring 2, and the fixing collar is fitted into the inner wall of the sliding groove.

[0012] Furthermore, an insert rod is inserted into the inner wall of the stabilizing column, a rubber plug is fixedly connected to the surface of the insert rod, a threaded ring is fixedly connected to the surface of the insert rod, the threaded ring is threadedly driven to the inner wall of the stabilizing column, and a rotating wheel is fixedly connected to the end of the insert rod away from the rubber plug.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting a sealing device, the sliding stopper rod is made more convenient to use when measuring liquids. When the rotating wheel rotates, the threaded rod and threaded groove are driven by the thread, causing the threaded rod to slide into the fixed groove. The threaded rod then drives the connecting plate to move, and the connecting plate is fixedly connected to the sliding stopper rod, causing the sliding stopper rod to slide into the fixed column. Then, the rubber stopper seals the fixed column, forming a sealed system in the measuring container. By setting a sealing device, accurate liquid measurement is facilitated, avoiding the need for operators to measure certain special liquids that require constant temperature sealing for more accurate measurement. Otherwise, differences in liquid density would reduce measurement accuracy, thus effectively improving the accuracy of the equipment.

[0015] 2. In this utility model, by setting up a draining device, it is convenient to control the discharge of liquid after measurement in the metering tank. When the rotating wheel two is rotated, the threaded ring fixedly connected to the surface of the insertion rod and the threaded drive of the inner wall of the stabilizing column cause the rubber plug two fixedly connected to the insertion rod to be pushed into the stabilizing column. Then the spring is compressed by force, and the sliding ring one and sliding ring two fixedly connected to both ends of the spring squeeze each other. When the rotating wheel two is rotated in the opposite direction, the spring is released from restraint and expands. Then the insertion rod slides out of the stabilizing column, causing the rubber plug two to slide out, the liquid outlet hole opens, and the water in the metering tank flows out through the liquid outlet hole. By setting up a draining device, it is convenient to control the flow of liquid in the metering tank after measurement, avoiding the inconvenience of liquid flow after measurement and the easy flow of liquid during measurement, which requires re-measurement, which is time-consuming and inconvenient. This effectively improves the convenience of the equipment. Attached Figure Description

[0028] The effect achieved by the above components is that by setting the sliding plug rod 805, it is easy to seal the water inlet hole 804.

[0029] Specifically, a rubber stopper 806 is fixedly connected to the surface of the sliding rod 805, a connecting plate 807 is fixedly connected to the end of the sliding rod 805 away from the rubber stopper 806, and a fixing groove 808 is fixedly connected to the surface of the metering barrel 7.

[0030] The effect achieved by the above components is that by setting the rubber plug 806, it is easy to seal the inner wall of the fixing column 803.

[0031] Specifically, a threaded rod 809 is inserted and connected to the inner wall of the fixed groove 808, a limit ring 810 is fixedly connected to the surface of the threaded rod 809, a threaded groove 811 is opened on the surface of the connecting plate 807, the threaded rod 809 and the inner wall of the threaded groove 811 are threadedly driven, and a rotating wheel 812 is fixedly connected to the surface of the threaded rod 809.

[0032] The effect achieved by the above components is that by setting the limit ring 810, it is easier to control the threaded rod 809 so that it does not fall off easily.

[0033] Specifically, a draining device 9 is fixedly connected to the surface of the metering barrel 7. The draining device 9 includes a stabilizing column 901, which is fixedly connected to the surface of the metering barrel 7. A drain hole 902 is fixedly connected to the surface of the stabilizing column 901.

[0034] The effect achieved by the above-mentioned components is that by setting the liquid outlet 902, it is convenient to control the discharge of liquid in the device.

[0035] Specifically, the inner wall of the stabilizing column 901 is provided with a sliding groove 903, a sliding ring 904 is fitted into the inner wall of the sliding groove 903, a spring 905 is fixedly connected to the surface of the sliding ring 904, a sliding ring 906 is fixedly connected to the end of the spring 905 away from the sliding ring 904, a fixing collar 907 is fixedly connected to the surface of the sliding ring 906, and the fixing collar 907 is fitted into the inner wall of the sliding groove 903.

[0039] Working Principle: By setting up a sealing device 8, the sliding stopper 805 is made more convenient to use when measuring liquids. Rotating the wheel 812 causes the threaded rod 809 to slide into the fixed groove 808 via threaded drive with the threaded groove 811. The threaded rod 809 then moves the connecting plate 807, which is fixedly connected to the sliding stopper 805, allowing the sliding stopper 805 to slide into the fixed post 803. The rubber stopper then seals the fixed post 803, forming a sealed system in the measuring container 7. The sealing device 8 facilitates accurate liquid measurement, avoiding the need for operators to measure certain special liquids that require constant temperature sealing for accurate measurement. Otherwise, differences in liquid density can reduce measurement accuracy. This effectively improves the accuracy of the equipment. Furthermore, the drainage device 9 facilitates the drainage of liquid from the measuring container 7 after measurement. The system controls the flow of liquid. Rotating the second rotating wheel 911 causes the threaded ring 910, fixedly connected to the surface of the insertion rod 908, to engage with the inner wall of the stabilizing column 901 via threaded transmission. This pushes the second rubber plug 909, fixedly connected to the insertion rod 908, into the stabilizing column 901. The spring 905 is then compressed, and the first sliding ring 904 and the second sliding ring 906, fixedly connected to both ends of the spring 905, press against each other. When the second rotating wheel 911 is rotated in the opposite direction, the spring 905 expands after being released from its restraint, causing the insertion rod 908 to slide out of the stabilizing column 901. This allows the second rubber plug 909 to slide out, opening the liquid outlet 902. Water in the metering tank 7 flows out through the liquid outlet 902. The drainage device 9 facilitates control of the liquid flow from the metering tank 7 after measurement, preventing inconvenience in liquid flow after measurement and avoiding the need for re-measurement during the measurement process, which is time-consuming and inconvenient. This effectively improves the convenience of the equipment.
