Abstract

The invention relates to a hinge, in particular to a hinge with a spring. The hinge comprises a base and first screw holes formed in the base. A locating hole is further formed in the base. The two ends of the base are fixedly connected with a shaft bracket baffle and a shaft sleeve support. The shaft sleeve support is connected with shaft sleeves at the two ends of a hinge body. A rotary shaft penetrates the shaft sleeves and is rotationally connected with limiting blocks and protective covers. Clamping grooves are formed in the two ends of the hinge body. The spring is wound around the surface of the rotary shaft. The two ends of the spring are located in the clamping grooves. The middle of the spring is bent in a strip shape and penetrates out of the locating hole. The hinge has the beneficial effects that the twisting force of the spring is well used, so that when a hitch cover is flatly placed, the gravity of the opened side is quite small and smaller than 20% of original gravity, and the hitch cover can be easily opened and closed by an operator; and when a patient feels uncomfortable or feels uncomfortable suddenly, the patient can use small force to push the hitch cover away by himself/herself to achieve the self-rescue purpose, and severe consequences are avoided.

Description

A kind of torsion spring hinge

Technical field

The present invention relates to a kind of hinge, particularly relate to a kind of hinge with spring.

Background technology

At present for the hatchcover of the fumigating bed of medical aspect, it opens and closes all to be combined by the gentle strut of hinge and realizes.Full hatchcover sub-volume is large, and mechanical strength is high, and deadweight is all more than 15 kilograms; In actual use, gas support is installed additional in the both sides of hatchcover, gas strut is in the real process of opening for fumigating bed full hatchcover, when opening angle is less than 15 °, gas support does not provide effective power-assisted, only have and just provide when angle is greater than more than 20 degree, so be need very large pulling force to be mentioned when starting to start hatchcover, bring the requirement in muscle power like this to operator; Simultaneously when closing hatchcover, when also very little lower than power-assisted upwards when 20 °, strength is needed to hold lid not too quickly detaining, in order to avoid it is unhappy and oppressive to make the psychology of patient cause equally.For meeting the designing requirement of full hatchcover, the length of gas support can not lower than 50 centimetres, and because the position of installing is all in its latter half, when patient goes to bed, leg is obstructed, and makes troubles for going to bed; In addition, gas support device will be installed at inside the body of fumigating bed cabin, that cabin body is inner, due to the structural principle of gas strut, under adding that gas support is in steam ambient for a long time, can be corroded faster, thus damage damping cylinder to its function degradation failure, support function inefficacy can cause: hatchcover opens non helping hand, and hatchcover freely falls easy patient harm, occurs that special circumstances people cannot operate relief.

Summary of the invention

For solving the defect that prior art exists, the object of this invention is to provide and a kind ofly make power-assisted value stabilization and safety, durable torsion spring hinge.

Technical scheme of the present invention is: a kind of torsion spring hinge, comprise base and be arranged on the first screw hole on base, described base is also provided with locating hole, base two ends are fixedly connected with pedestal baffle plate and sleeve rack, the axle sleeve at sleeve rack connection hinge two ends, turning cylinder is through axle sleeve, and be rotationally connected with limited block and protecting cover, described limited block is positioned on axle sleeve, described axle sleeve two ends are provided with packing ring, hinge two ends are provided with draw-in groove, spring wrap is in turning cylinder surface, both ends of the spring is positioned at draw-in groove, be bent into bar shaped and pass from locating hole in the middle of spring, described hinge is provided with the second screw hole, 3rd screw hole and clip cap bore, buckle closure is fixedly connected with axle sleeve by clip cap bore.

Described hinge, turning cylinder, spring adopt resistant material to make.

Described hinge, turning cylinder surface degree nickel form.

The invention has the beneficial effects as follows: multiple mechanical function is required to combine on a device, the effect that the function of existing hinge has again power-assisted to support; Owing to being arranged on the another face of cabin body, so patient does not hinder when going to bed, facilitate operator and patient; Well make use of spring and turn round stubborn power, hatchcover is made to open the gravity of side when keeping flat very little, lower than 20% of original gravity, operator can easy to do opening and closing hatchcover, when patient have uncomfortable sensation or burst not in good time, patient oneself just can push hatchcover open by little strength and arrive and save oneself, avoid greeting personnel not in time with unable election hatchcover and the generation of serious consequence that causes; This hinge adopts resistant material or general steel later stage electric plating method to make, and solves corrosion of vapor problem; Protecting cover and buckle closure design, make overall hinge possess waterproof and dustproof, guarantee safe action and aesthetic property.
