Abstract

The utility model discloses an anti-tip column-type weighing sensor, which comprises a pressure head, a column-type elastomer and a base. The weighing sensor is characterized in that two ends of the column-type elastomer protrude outwards along the central axis of the elastomer to form two lug bosses, an upper lifting shoulder and a lower lifting shoulder are formed on the body of the elastomer, the base and the pressure head each are provided with a concave pit for engagement with the lug bosses at two ends of the elastomer, end surfaces of the lug bosses at the two ends are in contact with the bottom parts of the corresponding concave pits, and certain suspension clearances are formed between the lower end surface of the pressure head and the upper end surface of the base and corresponding lifting shoulders. When a lateral impact force causes the weighing sensor to tip, shoulder parts of the elastomer can prop against the bottom part of the pressure head and the upper end of the base, so that the weighing sensor as a whole can avoid tipping, and the sensor can be endowed with improved anti-unbalanced loading capability.

Description

A kind of anti-pillar LOAD CELLS of toppling over

Technical field

The utility model belongs to the parts of weighing apparatus, and what relate to is sensor on the weighing apparatus, and what be specifically related to is a kind of pillar LOAD CELLS.

Background technology

The pole structure LOAD CELLS has been widely used in all kinds of electronic-weighing equipment such as electronic vehicle weighing apparatus, track scale.Existing column type sensor mainly is made up of the elastic body that is pasted with strainometer and top pressure head and bottom base, and the elastic body of column type sensor is that vertical direction is shelved on the base support body, and seaming chuck is to be shelved on elastomeric upper end equally.The column type sensor of this structure is toppled over when running into lateral impact easily, causes the damage of sensor.

The utility model content

The purpose of this utility model is to overcome the deficiency of existing pillar LOAD CELLS, proposes a kind of anti-lateral impact that has, anti-pillar LOAD CELLS of toppling over.

The technical scheme that realizes above-mentioned purpose is: a kind of anti-pillar LOAD CELLS of toppling over, comprise pressure head, column type elastomer and base, it is characterized in that: stretch out outside its central shaft alignment at the two ends of described column type elastomer, form two boss, on elastomeric body, form half the circumference of the sleeve where it joins the shoulder up and down, a pit that matches with described elastic body two ends boss is respectively arranged on described base and the pressure head, the contact of the end face of two ends boss and corresponding pit bottom, and between the upper surface of the lower surface of pressure head and base and each self-corresponding half the circumference of the sleeve where it joins the shoulder the certain unsettled gap of formation.

The size in above-mentioned unsettled gap is decided according to the diameter of elastomeric body, is generally 1-10mm.

When the utility model LOAD CELLS when being subjected to lateral impact power inclination took place, elastomeric shoulder will prop up the bottom of pressure head and the upper end of base, is unlikely to take place integral body to topple over, and can improves the anti-bias load ability of sensor.

Description of drawings

Fig. 1 is the unitary construction synoptic diagram of an embodiment of the utility model.

Among the figure: 1. pressure head, 2. column type elastomer, 3. base, 4. boss, 5. half the circumference of the sleeve where it joins the shoulder, 6. pressure head pit, 7. base pit, 8. unsettled gap, A. pressure head lower surface, B. base upper surface.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1, the utility model is anti-topples over the pillar LOAD CELLS, and main body is made up of pressure head 1, column type elastomer 2 and the strainometer and the base 3 that are attached on the column type elastomer 2.Stretch out outside its central shaft alignment at the two ends of column type elastomer 2, form upper and lower two boss 4, on the body of elastic body 2, form the half the circumference of the sleeve where it joins the shoulder 5 in upper and lower two orientation, a pit 6 that matches with elastic body upper end boss 4 is arranged on the pressure head 1, a pit 7 that matches with elastic body lower end boss 4 is arranged on the base 3, the end face of two ends boss contacts with corresponding pit bottom, form the unsettled gap of 5mm between the lower surface A of pressure head 1 and the elastic body top half the circumference of the sleeve where it joins the shoulder 5, also form the unsettled gap of 5mm between the upper surface B of base 3 and the elastic body bottom half the circumference of the sleeve where it joins the shoulder 5.

Claims

1. prevent toppling over the pillar LOAD CELLS for one kind, comprise pressure head, column type elastomer and base, it is characterized in that: stretch out outside its central shaft alignment at the two ends of described column type elastomer, form two boss, on elastomeric body, form half the circumference of the sleeve where it joins the shoulder up and down, a pit that matches with described elastic body two ends boss is respectively arranged on described base and the pressure head, the contact of the end face of two ends boss and corresponding pit bottom, and between the upper surface of the lower surface of pressure head and base and each self-corresponding half the circumference of the sleeve where it joins the shoulder the certain unsettled gap of formation.

2. prevent toppling over the pillar LOAD CELLS according to claim 1 is described, it is characterized in that: described unsettled gap is 1-10mm.
