Description

Technical Field

[0001] The utility model relates to the technical field of chemical liquid treatment, in particular to a liquid suction rake structure used for chemical liquid. Background Art

[0002] Chemical liquids refer to liquids with chemical properties, including pure substances and mixtures. Pure liquids include elements and compounds, such as bromine and its compound water; mixtures include solutions, such as sodium chloride dissolved in water to form sodium chloride solution. With the development of the semiconductor industry, various corrosive chemical liquids such as stripping fluids, etching solutions, acids, and alkalis have come into widespread use.

[0003] Currently, solutions leak during factory transportation, equipment commissioning, cleaning, and maintenance. Typically, after a liquid leaks onto the ground, it is absorbed by a special absorbent paper or cloth and then discarded. These absorbent paper or cloth are typically consumable and cannot be reused. Large-scale leaks require neutralization with acid or alkali powders before cleaning. To ensure a complete, one-time cleanup of the acid and alkali solutions on the ground, a liquid suction rake has emerged. However, existing liquid suction rakes for chemical liquids have a fixed structure, making them difficult to quickly collect and clean during cleaning. Therefore, we propose a liquid suction rake structure for chemical liquids. Utility Model Content

[0004] The purpose of the utility model is to provide a liquid suction rake structure for chemical liquids, which has the advantages of quickly collecting chemical solutions and improving their cleaning efficiency, and solves the problem that the existing liquid suction rake structure for chemical liquids is fixed and cannot be quickly collected and cleaned when cleaning chemical solutions, which brings inconvenience to people's use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: A liquid suction rake structure for chemical liquids, comprising a positioning plate and a movable sleeve, wherein the middle end of the bottom of the positioning plate is fixedly connected to a positioning main board, the front and rear ends of the positioning main board are movably connected to connecting pins, the front and rear ends of the positioning main board are movably connected to an adjustment plate through the connecting pins, the top of the adjustment plate away from the positioning plate is fixedly connected to a fixing pin, the bottom of the positioning main board and the adjustment plate are fixedly connected to an elastic connecting seat, the elastic connecting seat and the positioning main board and the middle end of the positioning plate are plugged with a handle, the lower end of the handle is provided with a ventilation conductor, the top of the movable sleeve is fixedly connected to a handle, the front and rear sides of the movable sleeve are fixedly connected to a movable frame, the bottom of the movable frame is fixedly connected to a limiting plate, a movable connecting rod is movably connected between the lower end of the movable frame and the fixing pin, positioning slots are provided at the left and right ends of the bottom of the elastic connecting seat, a rubber side baffle is plugged into the inner side of the positioning slot, and a limiting piece adapted to the elastic connecting seat is installed at the bottom of the adjustment plate away from the positioning plate.

[0006] Preferably, the longitudinal section of the elastic connecting seat is U-shaped.

[0007] Preferably, the longitudinal section of the positioning slot is an arc greater than 270 degrees, and the upper end of the rubber side baffle is adapted to the positioning slot.

[0008] Preferably, the number of the rubber side baffles is two, and the height of the rubber side baffles close to the movable frame is lower than the height of the rubber side baffles far from the movable frame.

[0009] Preferably, the adjustment plate is symmetrically provided with extended ears on both sides away from one end of the positioning plate, the bottom of the extended ears is fixedly connected to a fixed sleeve, the top of the inner cavity of the fixed sleeve is fixedly connected to a second spring, the bottom of the second spring is fixedly connected to a movable block sliding on the inside of the fixed sleeve, and a ball is provided at the middle end of the bottom of the movable block.

[0010] Preferably, the right end of the outer surface of the handle is fixedly connected to a positioning plate, the left side of the positioning plate is fixedly connected to a first spring sleeved on the outside of the handle, and the left end of the first spring is fixedly connected to a movable sleeve sliding on the outer surface of the handle.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] 1. The utility model is provided with positioning slots, rubber side baffles, elastic connecting seats and limit members. After the structure comes into contact with the ground, a certain gap is generated between the rubber side baffles close to the movable frame and the ground, which facilitates the chemical liquid to enter the space defined by the two rubber side baffles and the two limit members. Through the arrangement of the positioning plate, the adjusting plate, the movable frame, the limit plate, the movable sleeve, the handle, the movable connecting rod, the fixed pin and the positioning main board, when the handle drives the structure to clean the chemical liquid, when the movable sleeve is driven to move rightward on the outer surface of the handle, the movable sleeve can drive the movable frame to move synchronously, and when the movable frame moves, it will drive the movable connecting rod to move with the assistance of the limit plate. When the movable connecting rod moves, it can drive the adjusting plate to retract inward with the connecting pin as the center of the circle with the assistance of the fixed pin, thereby speeding up the collection of the chemical liquid and making it convenient for people to use.

[0014] 2. The utility model can limit the use height of the rubber side baffle through the arrangement of the extended ear, the fixed sleeve, the second spring, the movable block and the ball, thereby reducing the wear rate of the rubber side baffle during use and extending its later service life. When the ball and the movable block slide in the fixed sleeve to compress the second spring, it is convenient to adjust the size of the contact surface between the rubber side baffle and the ground according to the conditions of the ground to be cleaned. When the second spring is compressed, the lower end of the rubber side baffle will be more attached to the ground, making this structure suitable for uneven ground and expanding its scope of use.
