DESCRIPTION OF THE EMBODIMENTS

Referring to FIGS. 1 to 6, a novel mechanical platform scale includes a platform scale body 10, an upright column 11 arranged at one side end of the platform scale body 10, an adjustment mechanism 12 arranged at the top end of the upright column 11, and a pull rod 13.

In the present embodiment, a first wheel 101 and a second wheel 102 are arranged at the top of the other side end of the platform scale body 10 at an interval.

The platform scale body 10 includes a scale body supporting plate 104 used for weighing and a supporting framework 105 arranged outside the scale body supporting plate 104.

Specifically, the supporting framework 104 is provided with an accommodating space, and the scale body supporting plate 104 is accommodated in the accommodating space.

In the present embodiment, the accommodating space is rectangular, and the scale body supporting plate 104 is rectangular. Preferably, a length and a width of the scale body supporting plate 104 are slightly less than a length and a width of the accommodating space.

Further, the scale body supporting plate 104 is planar, that is, the scale body supporting plate 104 is a planar rectangle. It should be understood that the scale body supporting plate 104 is used for holding an object to be weighed.

Preferably, a horizontal plane where the scale body supporting plate 104 is located is the same as a horizontal plane where a top surface of the supporting framework 105 is located. That is, the top surface of the supporting framework 105 is also planar.

It should be understood that during normal weighing of an object, the scale body supporting plate 104 would easily damage the platform scale body 10 (a weighing structure) due to a sudden heavy stress if a relatively heavy object is directly placed in the scale body supporting plate 104. Since the horizontal plane where the scale body supporting plate 104 is located is the same as the horizontal plane where the top surface of the supporting framework 105 is located, in case of a need for weighing an object, the object can be moved into the supporting framework 105. As such, the phenomenon of easy damage to the platform scale body 10 due to the fact that the object is directly placed in the scale body supporting plate 104 can be avoided.

It is worth noting that the platform scale body 10 of the present embodiment further includes a weighing structure connected with the scale body supporting plate 104. That is, the scale body supporting plate 104 is suspended in the accommodating space by means of the weighing structure. The weighing structure may be implemented using a structure in the prior art, so the principle of the weighing structure will not be repeatedly described here.

The adjustment mechanism 12 is provided with a rectangularly planar top plate 121, and the top plate 121 is provided with a long-strip open slot 122 disposed along its lengthwise direction.

Preferably, the long-strip open slot 122 is arranged on one side edge of the top plate 121 to cause one side edge of the top plate 121 to form a supporting rod 123 used for supporting a weight. It should be understood that the weight can be clamped in the supporting rod 123 in the present embodiment. Since the top plate 121 is planar, more objects can be placed by means of the top plate 121.

Further, the other side edge of the top plate 121 is provided with a rectangular recess along its lengthwise direction, so that more objects can be accommodated by means of the recess.

It is worth mentioning that the adjustment mechanism 12 of the present embodiment further includes an adjustment structure connected with the weighing structure to realize weighing of an object by means of the scale body supporting plate 104, the weighing structure and the adjustment structure. The adjustment structure of the present embodiment can be implemented using a structure in the prior art, so it will not be repeatedly described here.

The pull rod 13 is rotatably arranged in one side end of the platform scale body 10. The top end of the pull rod 13 is provided with a pull handle ring 130, so that a person can hold the pull handle ring 130 with a hand to pull this mechanical platform scale to move.

In the present embodiment, one side surface of the other side end of the upright column 11 away from the platform scale body 10 is provided, along its lengthwise direction, with an accommodating groove 110 used for accommodating the pull rod 13.

Preferably, a clamping mechanism used for clamping the pull rod 13 in the upright column 11 is arranged in the upright column 11. That is, when the mechanical platform scale does not need to be moved, the pull rod 13 can be accommodated in the accommodating groove 110 of the upright column 11 by means of the clamping mechanism. When the mechanical platform scale needs to be moved, the pull rod 13 is taken out from the accommodating groove 110 of the upright column 11 to pull the mechanical platform scale.

In the present embodiment, the clamping mechanism includes a first fixed rod 111 arranged on one side of the accommodating groove 110 of the upright column 11, a second fixed rod 112 arranged on the other side of the accommodating groove 110 of the upright column 11, and a clamping rod 113 with one end rotatably arranged in the first fixed rod 111. A clamping slot 1121 used for accommodating the other end of the clamping rod 113 is formed in the second fixed rod 112. That is, the clamping rod 113 is rotated to cause the other end of the clamping rod 113 to be accommodated in the clamping slot 1121 when the pull rod 13 is accommodated in the accommodating groove 110 of the upright column 11, and this time, the clamping rod 113 clamps the pull rod 13.

In the present embodiment, one side end of the platform scale body 10 extends to be provided with an extending plate 103, and the pull rod 13 is rotatably arranged in the extending plate 103.

Further, a wheel mechanism is arranged in the extending plate 103, so that the mechanical platform scale can be moved by means of the wheel mechanism, the first wheel 101 and the second wheel 102.

The third wheel 143 is rotatably arranged between the first vertical plate and the second vertical plate.

In the present embodiment, the bottom end of the pull rod 13 is provided with a first protruding rod 131 and a second protruding rod 132 at an interval; the first protruding rod 131 is provided with a first through hole, and the second protruding rod 132 is provided with a second through hole corresponding to the first through hole; the top end of the connection rod 141 is provided with a third through hole corresponding to the first through hole; and first screws are arranged in the first through hole, the third through hole and the second through hole in a penetrating manner to cause the top end of the connection rod 141 to be rotatably connected with the bottom end of the pull rod 13.

Further, the wheel mechanism further includes a first fixed plate 144 arranged on the top surface of the extending plate 103, and a second fixed plate 145 arranged on a bottom surface of the extending plate 103. The extending plate 103 is provided with a first penetrating hole, and the first fixed plate 144 is provided with a second penetrating hole corresponding to the first penetrating hole; the second fixed plate 145 is provided with a third penetrating hole corresponding to the first penetrating hole; the connection rod 141 is arranged in the second penetrating hole, the first penetrating hole and the third penetrating hole in a penetrating manner. It should be understood that the extending plate 103 is clamped between the first fixed plate 144 and the second fixed plate 145.

In the present embodiment, two sides of the first fixed plate 144 respectively extend to be provided with a first fixed block 1441 and a second fixed block 1442, and the first fixed block 1441 and the second fixed block 1442 are arranged on the top surface of the extending plate 103 in a screw fastening manner. In the present embodiment, two sides of the second fixed plate 145 respectively extend to be provided with a third fixed block 1452 and a fourth fixed block 1453, and the third fixed block 1452 and the fourth fixed block 1453 are arranged on the top surface of the extending plate 103 in a screw fastening manner.
