Abstract

A high precision balance base comprises from the top and the bottom a stainless steel scale, an upper bracket, a sensor, a lower bracket and a balance feet. The scale cover is positioned in the upper bracket; the sensor is fixed between the upper bracket and the lower bracket. The upper bracket comprises an outline border, an inner border and a connection support fixed between the outline border and the inner border. The outline border and the inner border are both a square frame, wherein the outline border and the inner border of the upper bracket and the lower bracket all adopt the steel in the shape like a Chinese character ''Ao''. Compared with the original balance, the utility model greatly reduces the cost of the product, reduces the weight of product, increases the elasticity of the product, enhances the anti-strike capacity during the transportation process, increase the reliability of transportation.

Description

High precision platform scale base

[technical field]

The utility model is about a kind of electronic scale, is meant a kind of high precision platform scale base especially.

[background technology]

The base of existing platform scale adopts single weighing sensor, and its structure adopts two-layer support up and down, and there are following several problems in selecting for use and organization plan of timbering material:

1, cost height: for satisfying the requirement of intensity, two-layer up and down support all adopts " mouth " type guiding principle, makes materials many, causes material cost to increase.

2, manufacturability is poor: for the adjustment of overload protection, need be at the other WELD NUTS in upper bracket bottom, and make appearance poor and bad adjustment.

3, impact resistant capability is poor: owing to adopt " mouth " shaped steel, rigidity a little less than the elasticity, makes impact resistant capability weaken by force, causes sensor to damage easily.

4, Heavy Weight: because the organization plan materials are many, cause the scale body weight heavy, transportation cost also increases simultaneously.

[summary of the invention]

Technical problem to be solved in the utility model is to provide that a kind of cost is low, manufacturability is strong and reliable quality high precision platform scale base.

The utility model solves the problems of the technologies described above by the following technical programs: a kind of high precision platform scale base, comprise the stainless steel scale pan from top to bottom successively, upper bracket, sensor, lower carriage and scale pin, the scale pan covers on upper bracket, sensor is fixed between upper bracket and the lower carriage, upper bracket comprises housing, inside casing and be fixed on housing and inside casing between link, housing and inside casing are square framework, lower carriage comprises housing, inside casing and be fixed on housing and inside casing between link, housing and inside casing are square framework, wherein the housing of upper bracket and lower carriage, inside casing all adopts " recessed " shaped steel.

Place, four angles of the housing of lower carriage stretches out respectively and forms a boss, respectively offers a pair of screw on each boss, and wherein a screw screws in for the bolt on the scale pin, screws in a bolt as platform scale base overload protection on another screw.

The scale pin is fixed on the lower carriage bottom.

The advantage of the utility model high precision platform scale base is:

1, adopts single high precision weighing sensor,, make platform scale reach high precision in conjunction with special structural design.

2 compare with original platform scale, greatly reduce cost of products, have strengthened product manufacturability, reliability, have strengthened the market competitiveness.

3, the decline of weight support frame up and down, and flexible increase has strengthened the impact resistant capability in the transportation, improves the reliability of product in transportation.

[description of drawings]

The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 1 is the three-dimensional exploded view of the utility model high precision platform scale base.

Fig. 2 is an A-A sectional view among Fig. 1.

Fig. 3 is the constitutional diagram of the utility model high precision platform scale base.

[embodiment]

As shown in Figure 1, a high precision platform scale comprises gauge outfit 1, turning rack 2, stainless-steel tube 3 from top to bottom successively, and base.

Wherein base comprises the stainless steel scale pan 4, upper bracket 5, sensor 6, lower carriage 7 and scale pin 8.

After wherein gauge outfit 1 was fixed on the turning rack 2, pivoting was fixed on the top of stainless-steel tube 3, and the bottom of stainless-steel tube 3 is inserted in the sleeve 71 that lower carriage 7 one sides fixedly install.Gauge outfit 1 has display panel, is used for showing the weight of institute's scale object, thereby and can by rotation turning rack 2 adjust display panel on the gauge outfits 1 towards, be convenient to the user and watch.

The scale pan 4 covers on upper bracket 5, is used for placing the weight for the treatment of scale.

Upper bracket 5 comprises housing 52, inside casing 54 and link 56, upper bracket 5 plays fixation of sensor 6 and supports weight, in the present embodiment, housing 52 and inside casing 54 are square framework, link 56 is fixed between housing 52 and the inside casing 54, plays the effect that connects housing 52 and inside casing 54.Wherein housing 52, inside casing 54 all adopt " recessed " shaped steel, as shown in Figure 2, are the sectional view of upper bracket 5, under the state of proof strength, use the weight of " recessed " shaped steel minimizing material, to reach cost-effective purpose.Link 56 is simple steel disc, has both guaranteed the intensity of upper bracket 5, has also increased the elasticity of upper bracket 5 simultaneously, to reach the effect that strengthens impact resistant capability.

Sensor 6 is single high precision weighing sensor, and it is fixed on upper bracket 5 and the lower carriage 7 and between upper bracket 5 and lower carriage 7.This fixed form can adopt existing mode such as screw locking or buckle.When weight is pressed on the sensor 6, can produce signal and change, thereby be delivered to gauge outfit 1, reach the effect of measuring weight by cable.

Lower carriage 7 plays fixation of sensor 6 and is connected scale pin 8, it comprises housing 72, inside casing 74 and link 76, and in the present embodiment, housing 72 and inside casing 74 are square framework, link 76 is fixed between housing 72 and the inside casing 74, plays the effect that connects housing 72 and inside casing 74.The scaled down that is shaped as upper bracket 5 of lower carriage 7, wherein housing 72, inside casing 74 also all adopt " recessed " shaped steel, and link 76 also is to adopt simple steel disc.The place, four angles of lower carriage 7 stretches out respectively and forms a boss 78; respectively offer a pair of screw on each boss 78; wherein a screw screws in for the bolt on the scale pin 8; can be by adjusting the degree of depth of the bolt screw-in screw on the scale pin 8; adjust the height of lower carriage 7 apart from ground; screw in the overcurrent protection structure of a bolt 79 on another screw as the platform scale base; by swivel bolt 79 in this screw; can adjust the height of this overload protection upper end easily apart from the scale pan 4; simultaneously also strengthen manufacturability, saved the technology cost.

Scale pin 8 is used to make this high precision platform scale base support on the ground.

Can also between the upper bracket 5 and the scale pan 4, place the rubber crash roll, play antihunt action.
