Abstract

The utility model relates to the technical field of printers, in particular to a conductive spring for a printer. The conductive spring comprises a rolling and folding body with two ends respectively connected with an upper end head and a lower end head, the upper end head comprises a first spring column which is in twisted joint with a second spring column, a downward slant included angle is formed by the first spring column and the second spring column which is in twisted joint with a third spring column, and a downward slant included angle is formed by the second spring column and the third spring column. The upper end head is arranged to be of a structure that the downward slant included angles are formed among the first spring column, the second spring column and the third spring column, so that a spring component in an inner circle of a plastic member can be prevented from becoming warped from the middle, and rubbing-off of the spring caused by friction between the spring and a magnetic core can be avoided.

Description

A kind of printer power spring

Technical field

The utility model relates to the printer technology field, especially relates to a kind of printer power spring.

Background technique

Printer, requisite office appliance when having become people and handling official business, it makes people's work efficient be improved, and bar magnet and power spring are the requisite component of printer realization printing function, being engaged in of existing spring and working of plastics exists when plastics are pressed into aluminum pipe that the spring members in the circle can be to middle perk in the working of plastics in the printer magnetic roller, make rubbing of spring and magnetic core, the defective that time length can make spring rub.

The model utility content

At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of printer power spring, and it has can prevent rubbing of spring and magnetic core, the characteristics of avoiding spring to rub.

To achieve these goals, the technological scheme that the utility model adopts is: a kind of printer power spring, comprise the folded body of volume, the folded body two ends of volume are connected with upper tip and lower end respectively, described upper tip comprises first spring stack, first spring stack is twisted joint second spring stack that has downward-sloping angle with first spring stack, and second spring stack is twisted joint the 3rd spring stack that has downward-sloping angle with second spring stack.

Wherein, the angle between described first spring stack and second spring stack is 30 °～50 °.

Wherein, the angle between described second spring stack and the 3rd spring stack is 135 °～150 °.

Wherein, described lower end comprises first spring stack, and first spring stack is twisted joint second spring stack that has downward-sloping angle with first spring stack, and second spring stack is twisted joint the 3rd spring stack that has downward-sloping angle with second spring stack.

After adopting said structure, the utility model is compared the advantage that has with prior art: it comprises the folded body of volume, the folded body two ends of volume are connected with upper tip and lower end respectively, described upper tip comprises first spring stack, first spring stack is twisted joint second spring stack that has downward-sloping angle with first spring stack, second spring stack is twisted joint the 3rd spring stack that has downward-sloping angle with second spring stack, the utility model is by being arranged to upper tip first spring stack, second spring stack and the 3rd spring stack have the structure of downward-sloping angle each other, can prevent that like this spring members in the circle is to middle perk in the working of plastics, avoid because of the rubbing of spring and magnetic core, and spring is rubbed.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is structural representation of the present utility model.

Among the figure: 1, the folded body of volume; 2, upper tip;

3, lower end; 4, first spring stack;

5, second spring stack; 6, the 3rd spring stack.

Embodiment

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

As shown in Figure 1: a kind of printer power spring, comprise the folded body 1 of volume, folded body 1 two ends of volume are connected with upper tip 2 and lower end 3 respectively, described upper tip 2 or lower end 3 comprise first spring stack 4, first spring stack 4 is twisted joint second spring stack 5 that has downward-sloping angle with first spring stack 4, second spring stack 5 is twisted joint the 3rd spring stack 6 that has downward-sloping angle with second spring stack 5, the utility model is by being arranged to upper tip first spring stack 4, second spring stack 5 and the 3rd spring stack 6 have the structure of downward-sloping angle each other, can prevent that like this spring members in the circle is to middle perk in the working of plastics, avoid rubbing because of spring and magnetic core, and spring is rubbed, angle between described first spring stack 4 and second spring stack 5 is 30 °～50 °, preferably 45 ° of the utility model, angle between described second spring stack 5 and the 3rd spring stack 6 is 135 °～150 °, preferably 135 ° of the utility model, certainly the angle between described first spring stack 4 and second spring stack 5 and the angle between second spring stack 5 and the 3rd spring stack 6 can arrange flexibly according to actual conditions, as long as can prevent spring members to middle perk, effectively avoid spring to rub.

The above only is preferred embodiments of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.

Claims
