Preferably, described buffer gear comprises fixed head and buffer board;
Described fixed head is fixedly connected with fixed pedestal;
Described fixed pedestal is provided with dashpot, and described buffer board is arranged in dashpot and extends dashpot;
The side of described LOAD CELLS is fixedly connected with fixed pedestal, and opposite side is positioned on buffer board.
Preferably, described fixed head and buffer board are arranged in " L " type.
Preferably, described fixed head is connected with fixed pedestal bolt.
Preferably, described position-limit mechanism comprises location-plate and limiting plate;
Described location-plate is fixedly connected with fixed pedestal;
The upper side of described limiting plate and LOAD CELLS is conflicted mutually.
Preferably, described location-plate and limiting plate are arranged in " L " type.
Preferably, described location-plate is connected with fixed pedestal bolt.
Preferably, described position-limit mechanism is symmetricly set in the both sides of LOAD CELLS.
The utility model hinge structure is compared to be had: by the setting of snubber assembly, make when there being weight to drop on electronic balance, can not directly act in LOAD CELLS, can be cushioned external force by snubber assembly, LOAD CELLS is avoided directly to be smashed by weight, causing measurement inaccurate by arranging position-limit mechanism to avoid LOAD CELLS to rock, also avoiding pull-up LOAD CELLS and causing it to damage simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is explosive view of the present utility model.
In figure: 1, place plate; 2, LOAD CELLS; 3, fixed pedestal; 4, buffer gear; 5, position-limit mechanism; 6, fixed head; 7, buffer board; 8, dashpot; 9, location-plate; 10, limiting plate.
Embodiment
Shown in Fig. 2, embodiment is described further.
A kind of protective device of LOAD CELLS disclosed in the utility model, comprise and place plate 1, placement plate 1 is provided with the fixed pedestal 3 for fixing LOAD CELLS 2, fixed pedestal 3 is provided with for avoiding the instantaneous buffer gear 4 dropped of LOAD CELLS 2, buffer gear 4 comprises fixed head 6 and buffer board 7, fixed head 6 and buffer board 7 are in being wholely set, and fixed head 6 is " L " type with the shape of the structure of buffer board 7, fixed head 6 and buffer board 7 have certain elasticity to ensure its function cushioned, fixed head 6 is fixedly connected with fixed pedestal 3, fixed head 6 is connected with fixed pedestal 3 bolt, the hole that fixed head 6 wears for bolt is long lumbar hole, make it before fixing can Relative sliding, can accommodation limit load-carrying, it should be noted that herein, together with fixed head 6 can be relatively fixed by bolt with fixed pedestal 3, or can by welding, the ways customary such as clamping reach the object be fixedly connected with, above-mentioned connected mode, it is all technological means well-known to those skilled in the art, be not described further herein, fixed pedestal 3 is provided with dashpot 8, buffer board 7 is arranged in dashpot 8 and extends dashpot 8, the side of LOAD CELLS 2 is fixedly connected with fixed pedestal 3, opposite side is positioned on buffer board 7, LOAD CELLS 2 and fixed pedestal 3 are also bolted to connection, dashpot 8 to be positioned on fixed pedestal 3 and away from LOAD CELLS 2 one end with the fixation side of fixed pedestal 3, in installation process, fixed head 6 is fixed on after on fixed pedestal 3, ensure that buffer board 7 is fed through dashpot 8 simultaneously, and the diapire of dashpot 8 and buffer board 7 have certain gap, to ensure that buffer board 7 carries out having living space in the process cushioned allowing it change.
