The spacing piece (5) is corresponding to the external lateral surface of the sensor (2) and remains gaps. The components form an integral structure. The utility model has the advantages of simple installation, convenient debugging and maintenance, small environmental intrusion, high weighing precision, etc.

Description

Weighing module

The utility model relates to a kind of application structure of LOAD CELLS.

At present, when in electronic weighing system, LOAD CELLS being installed, need additional mechanism providing additional operations such as other supporting installing plate, because the installation form disunity causes complexity, time-consuming is installed, thereby be difficult to guarantee installation accuracy, can cause the weighting error of electronic weighing system, such weighing system is easy to be subjected to the interference of surrounding environment when weighing, as wind-force, air-flow, vibration etc., these all can influence weighing precision.

The purpose of this utility model provides a kind of Weighing module of integral body, and it is easy for installation, neither because of installation brings weighting error, can reduce the weighting error that environmental interference produces again.

The technical solution of the utility model is that sensor is fixedly mounted on the base plate, web member is housed on sensor, top board is housed on web member, fixedly connected finite place piece on the top board, locating part is corresponding with the lateral surface of sensor and leave the space, and the above-mentioned parts structure that forms a whole.

The utility model is owing to be to form the modular one-piece construction, when installing to, it does not need other annex when going in the electronic weighing system, integral installation is entered, install simple, debugging, safeguard all easily, guaranteed installation accuracy, thereby guaranteed the precision height of sensor, the characteristics that long-time stability are good make the weighting error of electronic weighing system little, precision is high.Simultaneously, behind fixedly connected finite place piece on the top board, locating part then plays the effect of resisting each horizontal direction external force, when the horizontal direction external impacts, at this moment, the suffered horizontal direction external force of top board makes locating part produce displacement, and make caging bolt withstand on the lateral surface of sensor, thereby horizontal direction external force is passed on the set bolt of sensor by locating part, thereby born the impact of horizontal direction external force, guaranteed high-precision weighing.

In addition, it is that two spheres of smooth sphere shake post that upper/lower terminal is arranged in the web member of the utility model between top board and sensor, because surface of contact is a smooth sphere about it, when anhydrous square of outward force, remain plumbness, guarantee the vertical stand under load of sensor, when disturbing factors such as wind-force, air-flow, vibration are arranged when surrounding environment, produce the horizontal direction external impacts, web member can depart from original position, and buffering external force is after impacting, two spheres in the web member shake post and can make it to produce a restoring force, return to original plumbness.

Below in conjunction with drawings and Examples the utility model is further described.

Accompanying drawing 1 is the structural representation of Weighing module.

Accompanying drawing 2 is a Weighing module side-looking structural representation.

Accompanying drawing 3 is the web member structural representation.

Shown in Fig. 1～3, sensor (2) is fixedly mounted on the base plate (1) by bolt (7), make sensor (2) become the overarm shape, on sensor (2), web member (3) is housed, have on one in the web member (3), two spheres that following two end faces are smooth sphere shake post (11), two spheres shake post (11) and are cylindrical shape substantially, on it, place, following both ends can have ring groove and the O-ring seal (9) of dustproof usefulness is housed, two spheres shake post (11) outside can be set with a cylindrical sleeve (10), cover plate (8) is arranged on sleeve (10), top board (4) is housed on web member (3), top board (4) is gone up fixedly connected finite place piece (5), locating part (5) is corresponding with the lateral surface of sensor (2), and leave the space, caging bolt (6) is arranged, the size that can regulate the space by caging bolt (6) on the locating part (5).Locating part (5) can be contained in and the corresponding position of sensor (2) end face, also can be contained in left surface or the corresponding position of right flank with sensor (2), can also be contained in the corresponding position, left and right side with sensor (2) simultaneously.

Claims (3)

1, a kind of Weighing module, it is characterized in that sensor (2) is fixedly mounted on the base plate (1), web member (3) is housed on sensor (2), top board (4) is housed on web member (3), top board (4) is gone up fixedly connected finite place piece (5), locating part (5) is corresponding with the lateral surface of sensor (2) and leave the space, and the above-mentioned parts structure that forms a whole.

2, Weighing module according to claim 1 is characterized in that web member (3) is that two spheres of smooth sphere shake post (11), O-ring seal (9), sleeve (10) and cover plate (8) and constitute by the upper/lower terminal face.

3, Weighing module according to claim 1 is characterized in that being equipped with on the stop means (5) caging bolt (6).
