The button lock can generate elastic deformation when bearing the weight of the container, and the tension of the button lock is detected by the strain gauge to obtain the weighing of the container.

The mounting grooves are oppositely arranged in two groups and distributed on two opposite sides of the button lock, the strain gauges on each mounting groove are Wheatstone bridges, and the strain gauges measure tension by means of the Wheatstone bridges.

Furthermore, the upper layer and the lower layer of the mounting groove are respectively provided with an annular groove, so that the stress of the mounting groove area where the strain gauge is located is more concentrated and uniform.

The tail end of the cable is connected with the AD module, the AD module is electrically connected with the display module, and the AD module converts an electric signal and finally displays the weight measurement on the display module.

The four groups of sensor structures are distributed at four opposite corners of the container, the unbalance loading condition of the whole container is calculated through the weight of the four opposite corners of the container, and the unbalance loading condition is directly displayed on the display module.

The above technical scheme of the utility model has following beneficial effect:

the utility model provides a buttonhock formula force transducer structure for weighing container weight, through directly setting up the mounting groove at buttonhock middle part and attached strainometer on the mounting groove, the weight of loading on the buttonhock directly obtains when making the hoist lift by crane the container, need not to set up in addition weighing device, and simple structure, does not change hoist overall structure, and on-the-spot simple to operate, use cost is low, and it is convenient to change, can replace the sensor structure together when the normal loss of buttonhock is changed.

Other advantageous effects of the present invention will be described in detail in the following detailed description.

Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments. It is to be understood that the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention. Furthermore, the technical features mentioned in the different embodiments of the invention described below can be combined with each other as long as they do not conflict with each other.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

As shown in fig. 1 and fig. 2, the embodiment of the present invention provides a button lock type force sensor structure for weighing a container, which comprises a button lock 1, wherein the top end of the button lock 1 is a fixed part 2, the bottom end is a weight hanging part 3 connected with the container, when the whole spreader locks and lifts the container, the weight of the container is applied to the button lock 1, and the button lock 1 can be stretched and deformed.

The middle part of the button lock 1 is a strain area, a mounting groove 4 is arranged in the strain area, a strain gauge 5 is pasted on the surface of the mounting groove 4, and the strain gauge 5 can detect strain and tensile force when the button lock 1 is stressed, stretched and deformed, so that the container can be weighed. The cover plate 6 covers the mounting groove 4 to protect the strain gauge 5 in a sealing manner so as to prevent the performance of the strain gauge 5 from being influenced by external unknown factors.
