Description
Technical Field
The invention relates to the field of injection pumps, in particular to a one-step locking pump clamping seat for an infusion rod with any diameter.
Background
The injection pump and the infusion pump are common medical equipment, can accurately, micro, uniformly and continuously pump the liquid medicine into the body, are convenient to operate, timed and quantitative, and can adjust the concentration and the speed of the medicine at any time according to the disease condition so that the medicine can keep the effective blood concentration in the body. When the pump is used, the pump needs to be fixed on a tower crane, a transfusion rod and the like, so that the operation is convenient, and particularly, the pump clamping seat is used as a carrier for fixing the pump in emergency, so that the operation is convenient and fast.
The pump clamping seats of the existing injection pumps and infusion pumps adopt thread rotary type locking devices, and when the locking devices are locked, a user needs to rotate the screw rod by one circle by hand to slowly approach and lock the screw rod. The operation is time-consuming and labor-consuming, and a locking judgment mechanism is not provided, so that whether the locking is complete or not cannot be judged.
Disclosure of Invention
The invention aims to solve the defects of the prior art and provides a one-step locking pump clamping seat for an infusion rod with any diameter, which can realize one-step locking on the infusion rod with any size.
The invention adopts the technical scheme for solving the technical problems that: the one-step locking pump clamping seat for the infusion rod with any diameter comprises a left clamping seat and a right clamping seat, wherein the right clamping seat and the left clamping seat form slidable fit, the right clamping seat is connected with an adjusting and locking mechanism through a connecting limiter, the adjusting and locking mechanism comprises a horizontal cam, a vertical cam, a self-locking nut, a locking handle and a stud, the vertical cam is located above the horizontal cam, the vertical cam and the horizontal cam are limited through the self-locking nut and can rotate around the stud, and the locking handle is connected with the vertical cam and can control the vertical cam to rotate.
Preferably, the groove at the bottom of the horizontal cam cooperates with the connection stop such that the horizontal cam has a limited range of rotation.
Preferably, the horizontal cam limit rotation range is 90 degrees.
Preferably, the horizontal cam reaches the highest point after rotating for 70 degrees.
Preferably, the connecting limiter is fixed with the right clamping seat through a U-shaped hole.
Preferably, the locking handle can rotate downwards, and a bayonet matched with the right clamping seat is arranged on the right clamping seat.
The invention has the beneficial effects that: through rotary motion, drive vertical cam and rise the increase vertical direction pressure and then increase horizontal friction, drive horizontal cam rotation simultaneously and promote the holder locking, easy operation is swift, is adapted to arbitrary size transfusion rod.

description of reference numerals: the clamping device comprises a left clamping seat 1, a right clamping seat 2, a self-locking nut 3, a locking handle 4, a horizontal cam 5, a vertical cam 6, a stud 7 and a connecting limiter 8.
Detailed Description
The invention will be further described with reference to the accompanying drawings in which:
example (b): as shown in fig. 1 and 2, the right holder 2 slides on the left holder 1 to form a pump holder clamping body, the self-locking nut 3, the locking handle 4, the horizontal cam 5, the vertical cam 6 and the stud 7 form an adjusting locking mechanism, the horizontal cam 5 and the vertical cam 6 form a vertical cam structure, the horizontal cam 5 and the right holder 2 form a horizontal cam structure, the self-locking nut 3 and the stud 7 control the overall height of the horizontal cam 5 and the vertical cam 6, the right holder 2 and the adjusting locking mechanism are connected into a whole by the connecting limiter 8, the right holder 2 can slightly move in the horizontal direction through the U-shaped hole in the connecting limiter 8, and the groove in the bottom of the horizontal cam 5 is matched with the connecting limiter 8 to limit the locking mechanism within a 90-degree rotation range.
When the pump clamping seat is in a state shown in fig. 3, the pump clamping seat is in an unlocking state, the locking handle 4 is pulled to adjust the opening so that an infusion rod can enter, then the locking handle 4 is pushed, the locking handle 4 drives the locking mechanism and the right clamping seat 2 to move together to be close to the infusion rod, after the right clamping seat 2 contacts the infusion rod, the locking handle 4 is rotated, the locking handle 4 drives the vertical cam 6 to rotate, when the vertical cam 6 rotates, the cam on the vertical cam 6 rises, the stud 7 is stretched, the pressure in the vertical direction is increased, the friction in the horizontal direction is increased, the locking mechanism and the right clamping seat 2 are prevented from retreating, meanwhile, the friction between the horizontal cam 5 and the inclined surface of the cam 6 is increased, the horizontal cam 5 is driven to rotate, when the horizontal cam 5 rotates, the horizontal cam 5 pushes the right clamping seat 2 to. When the locking handle 4 rotates by 70 degrees, the horizontal cam 5 reaches the highest point, then the locking handle enters into the equal-radius rotation, the vertical cam 6 continuously rises to increase the pressure in the vertical direction during rotation, the friction force in the horizontal direction is increased, the locking is further realized, and the retreating and loosening are prevented. At 90 degrees, the connecting limiter 8 is limited to clamp the horizontal cam 5 and cannot rotate, the vertical cam 6 is close to the dead point of the horizontal cam 5, the whole adjusting and locking mechanism cannot rotate, the bayonet from the locking handle 4 to the right clamping seat 2 is pressed, and the locking handle 4 is prevented from being mistakenly bumped to cause loosening, and the adjusting and locking mechanism is particularly shown in fig. 4.
In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the claims of the present invention.
