第(1)項記載の秤量装置の衝撃吸収機構。[Scope of Claim for Utility Model Registration] (1) A provision consisting of a load transmission pin inserted in the load transmission member of a weighing device and arranged vertically, and an elastic body supporting this load transmission pin, and applied to the load transmission pin. In a device that absorbs impact exceeding the specified value by elastic deformation of an elastic body, the load transmission pin is formed with a tapered part that widens in the direction of load application, and this part is formed in the insertion hole of the member through which the load transmission pin is inserted. forming a tapered hole corresponding to the tapered portion; further forming a hole connected to the tapered hole having an inner diameter that allows the tapered portion of the load transmission pin to move up and down;
Furthermore, the shock absorbing mechanism of the weighing device is configured to transmit the load of the object to be weighed and absorb the shock by tightly engaging the tapered portion of the load transmitting pin with the tapered hole using the elastic body. (2) A shock absorbing mechanism for a weighing device according to claim (1), wherein the elastic body is a coil spring. (3) A utility model characterized in that the bottom plate that houses the coil spring is screwed onto a member through which the load transmission pin is inserted, and the elastic force of the housed coil spring can be adjusted by rotating the bottom plate. A shock absorbing mechanism for a weighing device according to registered claim (2). (4) The weighing device according to claim 1, wherein the member through which the load transmission pin is inserted is a floating frame that constitutes a part of a low bar mechanism of an electronic balance. Shock absorption mechanism.
