Technical Field

[0001] This utility model relates to the field of dripping devices, specifically to a portable, large-capacity dripping device for corrosive liquids. Background Technology

[0002] In many fields such as chemical experiments and industrial production, dropping devices are often used to precisely add corrosive liquids to ensure the smooth progress of experiments or production processes. These fields have high requirements for the sealing performance, ease of operation, accuracy of the added volume, versatility, and portability of the dropping device.

[0003] However, existing corrosive liquid dispensing devices have many problems. Some devices have poorly designed outlets, making it difficult to accurately control the dripping position and affecting the dispensing effect; some devices lack graduations, making it impossible for users to visually understand the liquid volume in the reservoir, leading to inaccurate measurement of the dispensed liquid. Regarding sealing, existing devices have inadequate sealing structures, making leakage a common problem and threatening safety. Operationally, some dispensing devices are complex and lack flexible control over the dispensing process. Furthermore, existing devices often only fit specific reservoir sizes, lacking versatility and failing to meet diverse usage needs. In addition, many dispensing devices have difficulty adjusting the dripping angle, making them unsuitable for various dispensing scenarios, and they are not portable, causing inconvenience to users. Therefore, those skilled in the art have provided a portable, high-capacity corrosive liquid dispensing device to address the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned defects and provide a portable, large-capacity corrosive liquid dispensing device. A pointed nozzle is provided at the bottom of the storage tube for precise liquid control. A nozzle cap is fitted over the nozzle to prevent droplets from falling during the dispensing interval. Graduation lines on the outer wall facilitate measuring the amount of liquid dispensed. A screw cap connects to the storage tube via a thread, and a built-in sealing gasket ensures a leak-proof seal. A top pressing bolt causes the sealing plate to press down and dispense liquid, while a return spring helps it return to its original position. Operation is simple and flexible. The outer wall fixing ring can hold storage tubes of different specifications, and the angle and length of the support rod can be adjusted to adapt to various scenarios. The support rod can also be folded to fit the storage tube for easy portability. This invention addresses several shortcomings of existing dripping devices, including poor outlet design leading to inaccurate liquid control and affecting dripping efficiency; lack of graduations making it difficult for users to visually determine the liquid volume, resulting in inaccurate measurement; imperfect sealing structures causing leakage and safety threats; complex operation, lack of flexible liquid control; poor versatility, only compatible with specific size storage tubes; difficulty in adjusting the drip angle; inability to adapt to various scenarios; and lack of portability. The objective of this utility model is achieved through the following means: A portable, high-capacity corrosive liquid dispensing device includes a storage tube with a pointed outlet at its bottom. An outlet cap is fitted over the pointed outlet. A screw cap is fitted over the upper end of the storage tube, with a sealing gasket on the inner wall of the screw cap. A pressing bolt is vertically inserted into the center of the screw cap, with a sealing disc at its bottom. A return spring is fitted around the portion of the pressing bolt inside the screw cap. Graduation lines are provided on the outer wall of the storage tube. A retaining ring is wrapped around the outer wall of the storage tube, with an open end.

Then, the press button is released, and under the return spring's return contraction, the press button returns to its original position to wait for the next press to drip.

[0007] Furthermore, one end of the first internally threaded rod is rotatably engaged with one side wall of the opening of the fixing ring, and the middle part of the first internally threaded rod is threadedly engaged with the other side wall of the opening of the fixing ring. By rotating the first internally threaded rod, liquid storage tubes of different specifications can be clamped and positioned. One end of the second internally threaded rod is rotatably engaged with one side wall of the upper end of the telescopic support rod, and the middle part of the second internally threaded rod is threadedly engaged with the other side wall of the upper end of the telescopic support rod. By rotating the second internally threaded rod, the top of the telescopic support rod is clamped and retracted, thereby clamping and fixing the connecting block, so that the angle between the telescopic support rod and the fixing ring can be adjusted and fixed.

[0008] Furthermore, a support plate is installed at the bottom of the telescopic support rod to keep the telescopic support rod in a vertical position.

[0009] Furthermore, a suction cup is installed at the bottom of the telescopic support rod, which can be used to fix the telescopic support rod to the workbench surface to prevent the support rod from shaking and collapsing.

[0010] Furthermore, a U-shaped seat is installed at the bottom of the support rod, and a T-shaped groove is provided on the side wall of the U-shaped seat. A pressure plate is arranged horizontally inside the U-shaped seat. One end of the pressure plate is slidably engaged with the T-shaped groove. A pressure screw is rotatably connected to the bottom of the pressure plate. The pressure screw is threadedly engaged with the bottom side wall of the U-shaped seat. By rotating the pressure screw, the pressure plate can be moved up and down, so that the U-shaped seat can be clamped and positioned at the edge of the worktable.

[0011] The beneficial effects of this invention are as follows: This portable, large-capacity corrosive liquid dispensing device includes a storage tube with a pointed nozzle at the bottom for precise control of the liquid dispensing position. A nozzle cap is fitted over the pointed nozzle to prevent droplets from falling during dispensing intervals. Graduation lines on the outer wall allow users to visually understand the liquid volume within the storage tube, facilitating accurate measurement of the dispensing amount. A screw cap is threaded into the storage tube, and a sealing gasket is installed on the upper inner wall. After connection, the sealing gasket is compressed, effectively ensuring the internal sealing of the storage tube, preventing liquid leakage, and guaranteeing safe use. A pressing bolt is inserted at the top of the screw cap. Pressing the bolt causes the sealing plate to press down, dispensing the liquid. After release, the bolt returns to its original position under the action of a return spring, ready for another press. This design is simple to operate and allows for flexible control of the liquid dispensing. An opening on one side of the fixing ring surrounding the outer wall of the storage tube allows for clamping and positioning of storage tubes of different specifications by rotating the first internal threaded rod, improving the device's versatility. The connecting block on the other side of the fixing ring cooperates with the telescopic support rod. By rotating the second internal thread rod, the top of the support rod can be clamped and retracted, which can clamp and fix the connecting block. The angle between the telescopic support rod and the fixing ring can be adjusted and fixed, which can adapt to various drip angle and height requirements, meet different usage scenarios, and the support rod can be folded and fitted with the liquid storage tube for easy carrying.
