Abstract

A weighing sensor comprises an elastomer and a pressure head, wherein the pressure head is positioned at the upper end of the elastomer. The weighing sensor is characterized in that: the lower end of the elastomer is provided with a mounting baseplate, so that an electronic weighting device can be connected conveniently; besides, the mounting baseplate is provided with a level indication device which can be level indication bubbles which are horizontally and vertically arranged on the edges of the mounting baseplate, and can also be a universal level indication bubble which is arranged on one edge of the mounting baseplate. Compared with the prior art, the weighing sensor is provided with the level indication bubbles, that is, the weighing sensor has the level indication device itself, so that the whole mounting levelness is indicated and adjusted conveniently, the influence of errors generated by eccentric loads and inclination component forces is eliminated, and the precision and stability of the sensor in actual use are greatly improved.

Description

LOAD CELLS
Technical field
The utility model relates to the sensor on a kind of weighing apparatus, and what be specifically related to is a kind of LOAD CELLS.
Background technology
General column type sensor comprises elastic body, is positioned at the housing of elastic body outer wall, is located at the strainometer on elastic body.But the patent documentation referenced patent of this class number is the Chinese utility model patent " column weighting sensor " (Granted publication number is CN2685849Y) of CN200420020485.2.But general column type sensor offset load resistance is not enough, and to truck scale, claims that the body rigidity requirement is high, and application is not strong.
Column type sensor is widely used in the various electronic weighing appliances such as various track scales, bunker scale, platform scale.And while being used for truck scale, load is introduced mode, positioning inhibiting device etc. to be required comparatively harsh, anti-eccentric load and side load ability, the housing that is positioned at the elastic body outer wall easily lost efficacy, level is found in difficult installation accurately, be difficult to contraposition vertical, thereby affect scales accuracy of measurement and water proof and dust proof effect, practicality is not strong.But up to now, existing LOAD CELLS is not all installed horizontal indicating device, and the levelness of can't indication sensor installing has affected the precision and stability of the actual use of sensor.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of level of being convenient to thereby the error of elimination eccentric load and the generation of inclination component to be installed, to make the more accurate and stable LOAD CELLS of weighing for the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technical scheme that adopts: a kind of LOAD CELLS, include elastic body and pressure head, described pressure head is positioned at described elastic body upper end, it is characterized in that: described elastomeric lower end is provided with mounting base, and, be provided with on described mounting base can indication sensor the horizontal indicating device of installation level.
Preferably, described horizontal indicating device is the horizontal and vertical horizontal instruction foam that is distributed in described mounting base edge.
Preferably, described horizontal indicating device is the universal type horizontal instruction foam that is arranged on described mounting base one edge.
As improvement, the mounting groove of described horizontal indicating device is positioned at the edge of described mounting base, and opening simultaneously upward and outward.
As improvement, be provided with aviation socket on described elastic body, this aviation socket is threaded or is welded to connect with described elastic body.
As improvement, the lower surface of described elastomeric upper surface and described pressure head is interior concave spherical surface, and, be provided with the power transmission steel ball between described elastic body and pressure head.
Compared with prior art, the utility model has the advantage of:
1, the utility model LOAD CELLS is equipped with horizontal indicating device, be specially horizontal instruction foam, can indicate very easily and adjust whole installation level, eliminate the error effect that eccentric load and inclination component produce, thereby the some contact power transmission effect that keeps the power transmission steel ball, rolling by the power transmission steel ball can be eliminated the shock effect that transverse load is brought, and can automatically reset under Action of Gravity Field, has improved greatly the precision and stability of the actual use of sensor;
2, the utility model LOAD CELLS has horizontal instruction foam, when level is found in whole weighing apparatus installation accurately, sensor can be placed on the corresponding installed surface of weighing platform, determine the levelness that each is basic and make adjustment, simultaneously can, as level meter to the adjustment of giving instruction of the levelness of whole weighing platform face, facilitate weighing platform effectively to install.
3, the utility model LOAD CELLS is provided with aviation socket, can realize that the sensor signal cable is connected with the elastic body quick plug-in, conveniently installs, safeguards and organize fast scale, and have water proofing property.

Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Embodiment one
Fig. 1 is the structural representation of the utility model LOAD CELLS, includes elastic body 1, mounting base 2 and pressure head 3, and mounting base 2 is arranged on elastic body 1 lower end, conveniently with electronic scale, is connected, and pressure head 3 is positioned at the upper end of elastic body 1; Simultaneously, be provided with power transmission steel ball 4 between elastic body 1 and pressure head 3, the lower surface of the upper surface of elastic body 1 and pressure head 3 is the sphere of indent, and is suitable with the shape of power transmission steel ball 4; Be provided with horizontal instruction foam 5 on mounting base 2, be used to indicate the levelness of installation of sensors; Simultaneously, be provided with aviation socket 6 on elastic body 1, to realize that the sensor signal cable is connected with the elastic body quick plug-in, conveniently remove sensor and do the adjustment of base water Pingdu, and, aviation socket 6 can be threaded or be welded to connect with elastic body 1, to guarantee being connected and separating and water proofing property of signal cable and sensor.
Fig. 2 is the vertical view of the utility model LOAD CELLS the first embodiment, in this embodiment, and horizontal and vertical mounting base 2 edges that are distributed in of horizontal instruction foam 5, the levelness that common indication sensor is installed; The mounting groove of horizontal instruction foam 5 is positioned at the edge of mounting base 2, and opening simultaneously upwards outwards.
When sensor is pressed Fig. 1 direction forward and is installed, can be directly from the horizontal instruction foam 5 confirmation installation levels on mounting base; When sensor is put upside down and swung to while installing by Fig. 1 direction, still can observe horizontal instruction foam 5 by the export-oriented opening in the side of mounting base 2 and confirm installation level, because add the mounting groove that the keeps horizontal instruction foam 5 man-hour edge at mounting base 2, and opening upwards is outside, possesses lateral visual and can overlook.
