Specifically, the mounting seat 110 comprises a first housing 111 and a second housing 112 fixedly connected together. The first housing 111 and the second housing 112 are combined to form an installation cavity which is adapted to the shape of the weighing sensor 120. The installation cavity serves to protect the weighing sensor 120 from damage caused by external factors (such as impact, corrosion, etc.) and thus increases the service life of the weighing module 100. In the present embodiment, the first housing 111 and the second housing 112 are detachably fixedly connected through a buckle structure. Specifically, a plurality of buckling connecting clamping blocks and buckles are respectively and spaced apart provided on the opposite peripheral walls of the first housing 111 and the second housing 112.

It can be understood that the cavity wall of the installation cavity is provided with a first opening 1101 corresponding to the connecting hole of the weighing sensor 120 and a second opening 1102 corresponding to the lead of the weighing sensor 120. The first opening 1101 and the second opening 1102 are used to expose the connecting hole and the lead of the weighing sensor 120 on the mounting seat 110, so that the weighing sensor 120 can be connected to other components.

It can be understood that the weighing sensor 120 is electrically connected with the first plug 150 through the wire 122, and in the embodiment, the wire 122 can pass through the second opening 1102 so that the first plug 150 is exposed on the mounting seat 110, and at this time, the first plug 150 is movably arranged outside the mounting seat 110. In other embodiments of the utility model, the first plug 150 can be fixedly exposed on the mounting seat 110, and the second opening 1102 is arranged corresponding to the first plug 150 to mount the first plug 150.

When the fixing foot 132 is fixedly connected on the weighing sensor 120, there is a movable gap between the weighing disc 131 and the mounting seat 110. The base 140 comprises a supporting disc 141 and a fixing block 142 arranged integrally, and the fixing block 142 is arranged eccentrically on one side surface of the supporting disc 141. The fixing block 142 can be fixedly connected on the other connecting hole 121 of the weighing sensor 120 through a screw or the like threaded part. When the fixing block 142 is fixedly connected on the weighing sensor 120, there is a movable gap between the supporting disc 141 and the mounting seat 110. It can be understood that the above arrangement can ensure that the weighing sensor 120 can normally and accurately weigh. The above structure simplifies the structure of the electronic scale, which not only ensures the stable execution of the weighing function, but also makes the structure more simple and compact, and has the advantage of lower production cost.
