A hose blocking device

Abstract

The invention relates to a hose blocking-up device which comprises a hose clamping groove case (1), a rotating shaft (2), a locating screw (3), a contact switch (4), a motor fixing support (5) and a limiting screw (6). The hose clamping groove case (1) is a round barrel with the edge of the certain width. Through grooves used for placing hoses are formed in the bottom and the position of the side edge of the round barrel along the diameter direction. The limiting screw (6) is arranged on the position of the edge of the round barrel. The rotating shaft (2) is matched with the round barrel of the hose clamping groove case (1). The rotating shaft (2) rotates in the round barrel to block or enable liquid in the hoses to circulate. The locating screw (3) is arranged on the rotating shaft (2). The contact switch (4) is arranged on the inner side of the motor fixing support (5). The hose clamping groove case (1) and the motor fixing support (5) are mutually fixed. As the blocking-up device and a power supplying part are both arranged inside a round barrel model outer case, the hose blocking-up device is small, ingenious, simple in process, and capable of lowering material cost greatly.

Description

technical field [0001] The invention relates to a hose blocking device, which is generally used for blocking the flow of liquid in the hose. Background technique [0002] The hose blocking device is a liquid device commonly used on small flow devices, and is often used in laboratories and medical fields. The general hose blocking device on the market uses the motor to drive the ejector rod, and uses the mechanical pressure generated by the ejector rod to approach the bayonet to deform the rubber hose, thereby blocking the rubber hose. The disadvantage is that it is external, the mechanical processing is cumbersome, and the special motor needs to be customized, and another shell is required, which is large in size, takes up product space, and high in cost. The principle of this product is that when the motor rotates, the mechanical force between the bayonet on the special rotating stator and the bayonet on the outer cover structure causes the rubber hose to deform, thereby c...
