A tower spring with high life and high hardness and its production and processing technology

Abstract

The invention provides a high-life and high-hardness tower spring and its production and processing technology, which includes a rib top, two shock-absorbing dimples and two shoulders; The outer sides of each shock-absorbing pit are respectively provided with a shoulder, and the shock-absorbing pit and the shoulder are distributed symmetrically with the shock-absorbing pit and the shoulder on the other side respectively with respect to the longitudinal axis of the rib top, and the shoulder on one side of the rib top, The damping pits are jointly provided with integrally formed grooves, the grooves are symmetrically distributed with respect to the longitudinal axis of the rib top and the groove on the other side, the height of the rib top is greater than the height of the shoulder, and its production and processing technology includes molding, heat treatment and Anti-rust; the tower spring structure of the present invention, when any position is stressed, will still maintain a horizontal plane, and the pressure point on the cover plate and the pressing force of the infusion tube can be even, which can reduce the force deformation of the infusion pipeline and ensure Accuracy of high flow rate and long time infusion.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a high-life and high-hardness tower spring and its production and processing technology. Background technique [0002] At present, the infusion flow rate of domestic infusion pumps is basically within 2000ml / h. High-speed infusion pumps are blank in China. The structure that controls the infusion flow rate is mainly the internal pressure tube device. The elastic device in the pressure tube device structure of the existing infusion pump is mainly composed of 4 pieces. Composed of column springs and various limit structures, the internal structure is complicated, the parts are difficult to install, and the damage is not easy to repair, and the cover plate is large in size, which is not conducive to cost reduction and efficiency increase; since the four column springs are at both ends of the cover plate, the squeeze tube It will lead to uneven stress during the road, which will grea...

Problems solved by technology

[0002] At present, the infusion flow rate of domestic infusion pumps is basically within 2000ml / h. High-speed infusion pumps are blank in China. The structure that controls the infusion flow rate is mainly the internal pressure tube device. The elastic device in the pressure tube device structure of the existing infusion pump is mainly composed of 4 pieces. Composed of column springs and various limit structures, the internal structure is complicated, the parts are difficult to install, and the damage is not easy to repair, and the cover plate is large in size, which is not conducive to cost reduction and efficiency increase; since the four column springs are at both ends of the cover plate, the squeeze tube It will lead to uneven stress during the road, which will greatly deform the infusion pipeline, and cannot guarantee the output flow rate of the infusion pump and the accuracy of long-term infusion, and thus cannot meet the needs of emergency infusion. For medical outdoor first aid, high-speed blood transfusion, etc. Measures cannot produce positive and powerful effects

[0003] The first-generation tower spring solved the problem that the accuracy of infusion could not be guaranteed for a long time, but the service life and effect did not meet expectations, resulting in premature damage to the high-speed infusion pump purchased by the user, and it was not easy to repair, and the tower spring was about to be damaged when the critical value , due to the unsatisfactory elastic force, the accuracy of the infusion cannot be guaranteed, and the user cannot independently control the damage threshold of the infusion pump. The elasticity of the support, the movement is extremely violent, and it poses a problem for the standard of hardness and strength
