Description
Technical field
The utility model relates to weighing apparatus field, is more particularly a kind of spring balance.
Background technology
Spring balance is the apparatus of the weighing weight of object that a kind of relation utilizing the deformation of spring to be directly proportional to external force is made.In view of advantages such as spring balance are easy to carry, commonly used by people are daily, such as, for checking the article of who sell whether to claim enough when buying vegetables.The spring balance of prior art generally comprises scale body, extension spring and suspension hook, described extension spring is installed in scale body, and suspension hook is connected to the bottom of extension spring, is produced the change of corresponding scale by spring deformation, described scale characterizes the weight of article, thus realizes the object of weighing.
But, due to spring balance in use, extension spring can the normal power by stay cord, and the especially normal no to scale use because of overweight, extension spring can cause expendable deformation, thus affects the precision of spring balance.Therefore, the spring balance weighing precision decline after long-term use of prior art, affects the serviceable life of spring balance.
Utility model content
In view of this, the object of the utility model is to provide a kind of spring balance, to solve the low technical matters of weighing precision after the Long-Time Service existing for above-mentioned prior art.
Technical solution of the present utility model is, provide a kind of spring balance of following structure, comprise scale body, spring and suspension hook, described spring fitting is in scale body; Described spring is stage clip, described spring balance also comprises pulley blocks, described pulley blocks comprises two fixed pulleys, stay cord and briquettings, two described fixed pulleys are installed on the top of scale body and are positioned at the both sides of stage clip, described briquetting is connected to the lower end of stage clip, described stay cord walks around two fixed pulleys through briquetting, and the two ends of stay cord are connected on suspension hook.
Adopt above structure, the utility model compared with prior art, has the following advantages: adopt the utility model, adopts stage clip to replace the spring of prior art, the action direction of power is changed by pulley blocks, when suspension hook hangs the article wait weighing, under the effect of object gravity, act on stay cord two ends, stay cord around pulley to two Slideslips, now briquetting upwards acts on stage clip, makes stage clip lower end rises, thus realizes the effect weighing object; The utility model, due to the design of stage clip and pulley blocks, can prevent the deformation of stage clip generation irrecoverability, thus improve the weighing precision of product, extend its serviceable life.
Preferably, described briquetting is provided with displacement transducer, and described spring balance also comprises electronic display and multiplier, and described multiplier is electrically connected with displacement transducer and electronic display respectively.Like this, displacement transducer detects the change of briquetting displacement, and shift transformation information converted through multiplier, carry out numerical monitor by electronic display, readability is stronger.
Preferably, described compression spring sleeve is located at the guide pole be vertically arranged on scale body.
Preferably, described suspension hook comprises cross-tie and coupler body, and the length of described cross-tie equals the distance between two fixed pulley outward flanges, and described coupler body is connected to the centre position of cross-tie.Like this, stay cord can be made to be in vertical state, more balanced to the acting force of briquetting, weigh more accurate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model spring balance.
Shown in figure: 1, scale body, 2, spring, 3, suspension hook, 3.1, cross-tie, 3.2, coupler body, 4, fixed pulley, 5, stay cord, 6, briquetting, 7, displacement transducer, 8, guide pole.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but the present invention is not restricted to these embodiments.
The present invention contain any make on marrow of the present utility model and scope substitute, amendment, equivalent method and scheme.To have the utility model to make the public and understand thoroughly, in following the utility model preferred embodiment, describe concrete details in detail, and do not have the description of these details also can understand the utility model completely for a person skilled in the art.Meanwhile, the accompanying drawing of the utility model all to be illustrated as object, the not accompanying drawing of precise proportions.
As shown in Figure 1, spring balance of the present utility model, comprises scale body 1, spring 2 and suspension hook 3, and described spring 2 is installed in scale body 1; Described spring 2 is stage clip, described spring balance also comprises pulley blocks, described pulley blocks comprises two fixed pulleys 4, stay cord 5 and briquetting 6, two described fixed pulleys 4 are installed on the top of scale body 1 and are positioned at the both sides of stage clip, described briquetting 6 is connected to the lower end of stage clip, described stay cord walks around two fixed pulleys 4 through briquetting, and the two ends of stay cord 5 are connected on suspension hook 3.In addition, can existing techniques in realizing be adopted for the reading of spring balance and the conversion between spring displacement and reading, such as, adopt the form of circular dial scale to carry out reading, do not repeat at this, certainly also can be realized by structures such as following displacement transducers.
Described briquetting 6 is provided with displacement transducer 7, and described spring balance also comprises electronic display and multiplier, and described multiplier is electrically connected with displacement transducer and electronic display respectively.Displacement transducer detects the change of briquetting displacement, converts, carry out numerical monitor by electronic display according to shift transformation information through multiplier.Described multiplier by existing techniques in realizing, such as, can realize based on operational amplifier.Electronic display then can adopt charactron to realize.It should be noted that and all realize by hardware circuit.In order to view is clear, in figure, do not give display electronic display and multiplier.
Described compression spring sleeve is located at the guide pole 8 be vertically arranged on scale body 1.
Described suspension hook 3 comprises cross-tie 3.1 and coupler body 3.2, and the length of described cross-tie 3.1 equals the distance between two fixed pulley 4 outward flanges, and described coupler body 3.2 is connected to the centre position of cross-tie 3.1.Stay cord can be made to be in vertical state, more balanced to the acting force of briquetting, weigh more accurate.
