Description

Technical Field

[0001] The utility model relates to the technical field of an anti-impact structure for a platform scale, in particular to an anti-impact electronic platform scale. Background Art

[0002] Electronic platform scales are a type of weight measuring device that is commonly used in industry or farmers' markets. They are mainly used to weigh large quantities or large items. Many merchants in farmers' markets use electronic platform scales to weigh and then calculate prices. It is also a common weighing device in daily life.

[0003] Because sometimes it is necessary to weigh large and heavy items, if the items are not held firmly and suddenly fall, they will directly hit the scale. The impact force generated can easily damage the scale, causing the scale to be unusable or even directly damaged. For this reason, an anti-shock electronic scale is proposed. Utility Model Content

[0005] As a preferred technical solution of the utility model, four buffer plates are provided, and the four buffer plates are distributed in a diamond shape. One end of each two buffer plates is rotatably connected to a rotating column, and a side wall of one side of the rotating column is fixedly connected to a connecting plate, and the connecting plate is fixedly connected to the side walls on both sides opposite to the base and the force-bearing plate.

[0006] As a preferred technical solution of the utility model, the buffer plate is rotatably connected to a connecting plate at one end away from the connecting plate, and the connecting plate is fixedly connected to a fixed block at one end located in the buffer plate, and a damping telescopic column is fixedly connected between the two fixed blocks. A spring is sleeved on the damping telescopic column, and the spring is fixedly connected to the side wall of the fixed block through its two ends, and the connecting plate is fixedly connected to its inner wall at one end located in the inner groove.

[0007] As a preferred technical solution of the utility model, a top column is rotatably connected to the top side wall of the force-bearing plate near the middle of the four sides, a movable groove is opened inside one end of the top column, a plug column is telescopically connected in the movable groove, and a rubber pad is fixedly connected to the side wall of the movable groove at one end away from the plug column.

[0008] As a preferred technical solution of the utility model, the outer wall of one end of the top column away from the rubber pad is rotatably connected with a swivel, and the inner ring wall of the swivel is fixed with threaded teeth. The swivel is threadedly connected to one end of the plug column located in the movable groove through the threaded teeth. A slot is provided on the top of the force-bearing plate and on the side wall opposite to the plug column, and the plug column is inserted into the slot.

[0009] The utility model has the following advantages: the original bottom plate of the platform scale is divided into a force-bearing plate and a base, and a buffer plate and its components are connected between the force-bearing plate and the base. When a heavy object suddenly hits the placement plate, it will be pressed on the force-bearing plate as the force is transmitted. At this time, the force-bearing plate is pressed downward and also causes extrusion to the buffer plate. The buffer plate is compressed and deformed by the downward force, thereby pulling the spring to extend, and the spring has a rebound force that can alleviate the impact force generated, thereby reducing the damage to the platform scale caused by the impact. In order to prevent foreign objects from entering the middle of the base and the force-bearing plate and affecting the buffering effect, a movable enclosure is set up for enclosure. At the same time, when the mobile platform scale is hit, the movable enclosure will also shrink toward the middle of the base and the force-bearing plate, pushing the buffer plate to deform, thereby alleviating the force generated by the impact and improving the anti-impact safety performance of the platform scale.

[0015] The utility model will be further described below in conjunction with the accompanying drawings.

[0016] Please refer to Figure 1-4The utility model is an impact-proof electronic platform scale, comprising a placement plate 1, a buffer pad 2 is fixedly connected to the top side wall of the placement plate 1, a force-bearing plate 3 is set below the buffer pad 2, a base 4 is set at the bottom of the force-bearing plate 3 away from the placement plate 1, four movable enclosures 5 are set between the force-bearing plate 3 and the base 4, a telescopic support column 8 is fixedly connected to the middle of the top side wall of the base 4, and the other end of the telescopic support column 8 is detachably connected to the middle of the bottom side wall of the force-bearing plate 3, and inner grooves 6 are opened in the four movable enclosures 5, and buffer plates 7 are evenly set in the inner grooves 6;

[0017] There are four buffer plates 7, and the four buffer plates 7 are distributed in a diamond shape. One end of every two buffer plates 7 is rotatably connected to a rotating column, and a side wall of the rotating column is fixedly connected to a connecting plate 9, and the connecting plate 9 is fixedly connected to the side walls of the base 4 and the force-bearing plate 3 on both sides. The end of the buffer plate 7 away from the connecting plate 9 is rotatably connected to a connecting plate 10, and one end of the connecting plate 10 located in the buffer plate 7 is fixedly connected to a fixed block 11, and a damping telescopic column 12 is fixedly connected between the two fixed blocks 11. A spring 13 is sleeved on the damping telescopic column 12, and the spring 13 is fixedly connected to the side wall of the fixed block 11 through its two ends, and one end of the connecting plate 10 located in the inner groove 6 is fixedly connected to its inner wall.

[0018] The technical effect of this scheme is as follows: when an impact occurs, the force conduction will eventually suppress the force-bearing plate 3 to move downward, and as the force-bearing plate 3 moves downward, the buffer plate 7 will be suppressed. As the buffer plate 7 is suppressed and deformed, the conduction direction of the force is increased and converted, thereby reducing the damage caused by the impact force to the equipment. The expansion of the buffer plate 7 can also pull the spring 13 outward, and the elasticity of the spring 13 can relieve the force, further reducing the damage caused by the impact force. The damping telescopic column 12 can prevent the elasticity of the spring 13 itself from affecting the placement plate 1, and the buffer pad 2 connected to the top of the placement plate 1 can also absorb and relieve the force, so that it cooperates with the buffer plate 7 to minimize the impact of the impact force.

[0019] A top column 14 is rotatably connected to the top side wall of the force-bearing plate 3 near the middle of the four sides, a movable groove 15 is opened inside one end of the top column 14, a plug column 16 is telescopically connected in the movable groove 15, a rubber pad is fixedly connected to the side wall of the movable groove 15 at one end away from the plug column 16, a swivel 17 is rotatably connected to the outer wall of the end of the top column 14 away from the rubber pad, threaded teeth are fixed on the inner ring wall of the swivel 17, the swivel 17 is threadedly connected to one end of the plug column 16 located in the movable groove 15 through the threaded teeth, a slot 18 is opened on the top of the force-bearing plate 3 and the side wall opposite to the plug column 16, and the plug column 16 is inserted into the slot 18.

[0020] The technical effect of this solution is as follows: if a collision occurs during the movement, the movable enclosure 5 will be impacted first, because the movable enclosure 5 is in a protruding outward state. When the movable enclosure 5 is impacted, it will be compressed and moved toward the inside between the force-bearing plate 3 and the base 4, thereby impacting one end of the buffer plate 7. At this time, the end of the buffer plate 7 that is under force may move and deform, and the force can be buffered by the damping telescopic column 12 and the spring 13, thereby reducing the impact of the collision.

[0021] Specifically, when the utility model is used, when the weighing object is placed on the placement plate 1 and accidentally falls and hits the placement plate 1, the impact force generated will gradually be transmitted downward, and finally the force-bearing plate 3 will be driven to descend. As the force-bearing plate 3 descends, an extrusion force will be generated on the buffer plate 7, causing the force to expand outward along the rotation of the rotating column, thereby changing the direction of force transmission and reducing the damage caused by the impact force through the expansion and contraction of the spring 13 and the damping telescopic column 12. When the movable enclosure 5 is hit, one end of the buffer plate 7 will be deformed and moved, thereby alleviating the damage caused by the impact. When the platform scale is not used for a long time, the laid-down top column 14 can be adjusted to an upright state, and the placement plate 1 is supported by the top column 14 in the upright state to ensure that the placement plate 1 will not be forced to descend and cause the platform scale to start accidentally. The rotating swivel 17 inserts the plug column 16 into the slot 18 through a threaded connection to ensure the stability of the top column 14 in the upright state.

It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
