Abstract

The utility model discloses a spring for stirring. The spring for stirring comprises a spring body, a second fixing end and a first fixing end, wherein the second fixing end and the first fixing end are arranged at two ends of the spring body which is formed by metal wire materials in a curling and overlaying mode, the spring body comprises tightening sections and loosening sections, a second tightening section and a first tightening section are connected with the second fixing section and the first fixing section, and the loosening sections are evenly arranged between the second tightening section and the first tightening section at intervals. When stirring is conducted, the second fixing end and the first fixing end are driven to rotate through a mechanical device, the spring body is enabled to rotate and shake to stir, the loosening sections are additionally arranged so as to reduce the number of coils of the spring, consumable materials of the spring are few, and cost is reduced. In addition, the weight of the spring is lowered, energy which is consumed when stirring is conducted is few, and the effects of energy saving and environment protection are achieved.

Description

The spring that is used for stirring

Technical field

The utility model relates to a kind of spring, especially a kind of spring for stirring.

Background technique

Spring is a kind of mechanical parts that utilize elasticity to come work.Generally make with spring steel.Impact or shake, store up the size of energy, measuring force etc. in order to motion, the mitigation of controlling parts, be widely used in machine, the instrument.Spring is an accumulator just, and it has the function of stored energy, but can not discharge energy at leisure, realize that this function of slow release should lean on " spring+big speed ratio mechanism " to realize, is common in mechanical watch.Spring had just been used very early, and the bow in ancient times and crossbow are exactly two kinds of sensu lato springs.By stressed character, spring can be divided into extension spring, Compress Spring, torsion spring and flexural spring, belleville spring, annular spring, leaf spring, helical spring, valute spring and torsion bar spring etc. can be divided into by shape, cold coiling spring and hot coiling spring can be divided into by working process.The common cylinder spring is simple owing to making, and can make various types according to the stand under load situation, and is simple in structure, therefore most widely used.In general the manufactured materials of spring should have high limit of elasticity, fatigue limit, impact toughness and good heat treatment performance etc., and commonly used have carbon spring steel, alloy spring steel, rustproof spring steel and Cuprum alloy, nickel alloy and a rubber etc.The manufacture method of spring has cold coiling method and hot rolling method.Some spring also will be suppressed or shot blast after making, and can improve the bearing capacity of spring.

The spring that is used for stirring is a kind of special spring, utilize the elastic force of spring, swing to reach the purpose of stirring, existing spring for stirring, comprise the spring body and be located at the second fixed end and first fixed end at spring body two ends, described spring body is formed by stacking by metal wire rod is curling, the tight porousness of its number of coils is consistent, effect is general during stirring, and consumptive material is more, and cost is higher, and spring weight is also larger in addition, needed power is also larger when expending during stirring, consumes energy higher.

The model utility content

Problem to be solved in the utility model is to improve the problem that consumptive material is more, cost is higher that is used for the spring of stirring in the background technique.

In order to overcome the above problems, the utility model provides a kind of spring for stirring, comprise the spring body and be located at the second fixed end and first fixed end at spring body two ends, described spring body is formed by stacking by metal wire rod is curling, described spring body comprises tight section and loose section, link to each other with the second fixed end and the first fixed end one section is the second tight tight section of section and first, described second closely section and first closely between the section interval be provided with uniformly loose section and loose section.

The interval is provided with three sections loose section and two sections loose section uniformly between the described second tight section and the first tight section.

Described second closely section and first closely the number of coils of section be 5 to 7 circles, described second closely section and first closely between the section closely the number of coils of section be 2 to 3 circles, described second closely section and first closely between the section number of coils of loose section be 4 to 5 circles.

Spring for stirring described in the utility model, comprise the spring body and be located at the second fixed end and first fixed end at spring body two ends, described spring body is formed by stacking by metal wire rod is curling, described spring body comprises tight section and loose section, one section that links to each other with the second fixed end and the first fixed end is closely section of the second tight section and first, the interval is provided with loose section and the section of loosening uniformly between the described second tight section and the first tight section, during stirring, the second fixed end and the first fixed end are passed through the mechanical device driven rotary, so that spring body rotation whipping stirs, reach the minimizing number of coils by adding loose section, so that the spring consumptive material is less, cost, in addition, spring weight has also reduced, and energy spent during stirring is less, has reached the effect of energy-conserving and environment-protective.

Description of drawings

Accompanying drawing 1 is the schematic diagram of the spring for stirring described in the utility model

Marginal data: 1, spring body; 11, the first fixed end; 12, the second fixed end.

Embodiment

Below in conjunction with accompanying drawing a kind of spring for stirring of the utility model is described further.

As shown in Figure 1, the spring that is used for stirring of the present embodiment, comprise spring body 1 and be located at the second fixed end 12 and first fixed end 11 at spring body 1 two ends, spring body 1 is formed by stacking by metal wire rod is curling, spring body 1 comprises tight section and loose section, link to each other with the second fixed end 12 and the first fixed end 11 one section is the second tight tight section of section and first, second closely section and first closely between the section interval be provided with uniformly loose section and loose section.During stirring, the second fixed end and the first fixed end are passed through the mechanical device driven rotary, so that spring body rotation whipping stirs, reach the minimizing number of coils by adding loose section, so that the spring consumptive material is less, cost, in addition, spring weight has also reduced, and energy spent during stirring is less, has reached the effect of energy-conserving and environment-protective.

In the present embodiment, the interval is provided with three sections loose section and two sections loose section uniformly between the described second tight section and the first tight section.This is designed to preferably structure, can reach better mixing effect, can certainly be transformed to more loose section and loose section.

In the present embodiment, described second closely section and first closely the number of coils of section be 5 to 7 circles, second closely section and first closely between the section closely the number of coils of section be 2 to 3 circles, second closely section and first closely between the section number of coils of loose section be 4 to 5 circles.This is designed to preferably structure, can reach better mixing effect, can certainly be transformed to the number of coils more or still less.

The utility model is not limited to above embodiment and conversion.
