Abstract
The utility model relates to the technical field of printers, in particular to a modified conductive spring for printers. The modified conductive spring for printers comprises a coiled body. Two ends of the coiled body are connected with an upper end and a lower end respectively. A spring post tilting down is formed at the upper end in an extending manner and is parallel with the ground. The lower end comprises a first spring post connected with a second spring post in a twisted manner. The second spring post is connected with a third spring post in a twisted manner. The coiled body, the upper end, the lower end, the spring post, the first spring post, the second spring post and the third spring post are integrated. The spring posts which tilt down and are parallel with the ground are formed at the lower end in an extending manner, so that a magnet bar can be placed stably and electric conduction is facilitated. In addition, a spring part inside a plastic part can be prevented from tilting up, and spring breakage caused by wear between the spring and a magnet core is avoided.
Description
Technical field
The utility model relates to the printer technology field, especially relates to a kind of improved 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 one end 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, and the other end of spring can be to the inner bending of spring body, it is unstable that bar magnet is placed, and bar magnet placement shakiness can make the printer contact bad.
The model utility content
At the deficiency that above-mentioned prior art exists, the purpose of this utility model provides a kind of improved printer power spring, and it has can prevent rubbing of spring and magnetic core, avoids spring to rub, simultaneously the good characteristics of conductive effect.
To achieve these goals, the technological scheme that the utility model adopts is: a kind of improved 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 is extended with the spring stack of downward perk, this spring stack is parallel to the ground, described lower end 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, and described volume is folded body, upper tip, lower end, spring stack, first spring stack, second spring stack and the 3rd spring stack are one-body molded.
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 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, described lower end is extended with the spring stack of downward perk, and this spring stack is parallel to the ground.
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 is extended with the spring stack of downward perk, this spring stack is parallel to the ground, described lower end 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 extended with downward perk and spring stack parallel to the ground at lower end, bar magnet is placed steadily, be beneficial to conduction, in addition upper tip is arranged to 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;
7, 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 improved 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 is extended with the spring stack 7 of downward perk, this spring stack 7 is parallel to the ground, described lower end 3 comprises 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, 5 posts are twisted joint the 3rd spring stack 6 that has downward-sloping angle with second spring stack 5, described volume is folded body 1, upper tip 2, lower end 3, spring stack 7, first spring stack 4, second spring stack 5 and the 3rd spring stack 6 are one-body molded, the utility model is by being extended with downward perk and spring stack 7 parallel to the ground at lower end 3, bar magnet is placed steadily, be beneficial to conduction, in addition upper tip is arranged to 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.
