Description

Technical Field

[0001] The utility model relates to the technical field of rubber suction nozzles, in particular to a high-temperature resistant rubber suction nozzle. Background Art

[0002] A rubber nozzle is a nozzle made of rubber material and is commonly used in various industrial and medical equipment to absorb liquids or gases. Due to its good elasticity and sealing properties, the rubber nozzle can fit tightly to the openings of containers of various shapes to achieve effective suction function.

[0003] At present, the rubber nozzle can maintain its physical and chemical properties unchanged at higher temperatures, so the rubber nozzle has the characteristics of high temperature resistance. When the existing rubber nozzle is in use, the user drives the test tube to move by the mounting plate, so that the positioning rod enters the inner cavity of the shell, thereby starting the positioning effect. After the positioning rod enters the inner cavity of the shell, the user presses the limit rod, and the movement of the limit rod drives the movable plate to pull the tension spring, so that the limit rod enters the inner cavity of the limit hole. After the limit rod enters the inner cavity of the limit hole, the user rotates the connecting rod through the bearing, and the movement of the connecting rod drives the limit block to move, and then the reaction force of the tension spring causes the limit block to enter the inner cavity of the limit groove, thereby limiting the limit rod so that the limit rod will not separate from the inner cavity of the limit hole, thereby achieving the purpose of connecting and sealing the test tube and the nozzle body. However, when using the existing rubber nozzle, the user needs to perform multiple steps to complete the connection and sealing of the rubber nozzle, which not only increases the complexity of the operation, but may also cause the connection process to take more time, thereby reducing work efficiency.

[0004] Therefore, it is necessary to provide a new high temperature resistant rubber suction nozzle to solve the above-mentioned technical problems. Utility Model Content

The inner wall of the limiting groove is slidably connected to the limiting component, and the limiting component is fixedly connected to one end of the suction nozzle body adjacent to the test tube.

[0013] Compared with the related art, the high temperature resistant rubber nozzle provided by the present invention has the following beneficial effects:

[0014] Through the provided connecting device, when the rubber straw needs to be connected to the test tube, the limiting assembly is first moved to squeeze the limiting assembly, and then the limiting assembly is inserted into the limiting groove opened on the connecting block. When the limiting assembly moves into the limiting groove, the sliding block is squeezed. At the same time, the sliding block compresses the limiting plates and elastic parts set on both sides of itself, so that the sliding block is inserted into the inner wall of the groove opened on it, thereby realizing the connection between the rubber straw and the test tube.
