Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
A peristaltic pump head clamping sheet comprises a clamping sheet body, an upper clamping sheet pressing block and a compression spring, wherein the upper clamping sheet pressing block is positioned below the clamping sheet body; the upper card pressing block is hinged with the card body, and a first hinge pin hinged with the upper card pressing block is positioned at the upper left corner of the upper card pressing block; the compression spring is located between the card body and the upper pressing block of the card and tightly presses the upper part of the upper pressing block of the card.
Further, the compression spring is tightly pressed on the upper right corner of the pressing block on the card.
Furthermore, the device also comprises an adjusting seat, and the compression spring is positioned in the adjusting seat; the adjusting seat is connected to the card body.
Furthermore, adjust the seat and articulate on the card body, its articulated second round pin axle perpendicular to adjusts the axis and the card body of seat.
Further, a knob is arranged above the adjusting seat; the tail end of the knob is in threaded connection with the adjusting seat, and the tail end of the knob is tightly pressed right above the compression spring.
Furthermore, still include the card thimble, the card thimble is located between briquetting on compression spring and the card.
Furthermore, the top end of the card thimble extends into the adjusting seat and is connected to the bottom of the compression spring.
The following is a more specific example:
as shown in fig. 1 to 4, the present embodiment includes a card body 6, a card upper pressing block 5 located below the card body, and a compression spring 4; the upper card pressing block is hinged with the card body, and a first pin shaft 7 hinged with the upper card pressing block is positioned at the upper left corner of the upper card pressing block; the compression spring is located between the card body and the upper pressing block of the card and tightly presses the upper part of the upper pressing block of the card. The compression spring is tightly pressed on the upper right corner of the pressing block on the card.
The embodiment also comprises an adjusting seat, wherein the compression spring is positioned in the adjusting seat; the adjusting seat is connected to the card body. The adjusting seat is hinged on the card body, and the second pin shaft 2 which is hinged with the adjusting seat is vertical to the axis of the adjusting seat 9 and the card body. A knob 1 is arranged above the adjusting seat; the tail end of the knob is in threaded connection with the adjusting seat, and the tail end of the knob is tightly pressed right above the compression spring.
The embodiment further comprises a card ejector pin, and the card ejector pin is located between the compression spring and the card upper pressing block. The top end of the card thimble extends into the adjusting seat and is connected to the bottom of the compression spring.
The utility model discloses still include flexible locking arm 8, flexible locking arm is used for fixing the pump head card in the pump head main part, and its bottom is equipped with the recess that corresponds with the square iron of pump head main part.
The knob transmits pressure to the pressing block on the card through the compression spring 4 and the card thimble 3. When the knob rotates rightwards, the compression spring is compressed, downward pressure applied to the pressing block on the clamping piece is increased, then the pressing block rotates clockwise around the rotating shaft, the pressing pipe gap is reduced, and the pressure on the hose is increased. When the knob rotates leftwards, the compression spring extends, downward pressure on the pressing block on the clamping piece is reduced, then the pressing block rotates anticlockwise around the rotating shaft, the pressure pipe gap is enlarged, and the pressure on the hose is reduced.
When there is machining error in the hose, or produced wearing and tearing in the course of the work, under the effect of spring force, briquetting can compensate and finely tune according to the actual atress condition is automatic on the card.
When the device is in a working state, the combination of the knob, the adjusting seat, the compression spring, the clamping piece thimble and the like is in a working position as shown in figure 3. When the shutdown stops working, the combination can be placed in the shutdown position. In the idle position, the hose is subjected to a pressure which is eliminated or significantly reduced, which significantly increases the service life of the hose.
