For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] A weighing device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0032] Reference Figure 1 , Figure 2 and Figure 3 A weighing device according to an embodiment of the utility model includes a base frame 100, a weighing sensor 120, a display 130 and a buffer mechanism.

[0033] Regarding the base frame 100 , a weighing plate 110 is disposed on the base frame 100 . The weighing plate 110 is used to support the object to be weighed, thereby facilitating the weighing device to support the object to be weighed.

[0034] In some specific embodiments, the base frame 100 includes a frame body 230 and a frame foot 240 supporting the bottom of the frame body 230. The space between the frame body 230 and the bottom surface is used to avoid the front wheels of the forklift, thereby preventing the base frame 100 from hindering the forklift from moving forward to deliver the items to be weighed to the weighing plate 110.

[0035] In some specific embodiments, a first vertical rod 250 is provided at the bottom of the weighing plate 110, and the base frame 100 is provided with a first guide hole extending up and down. The first vertical rod 250 and the first guide hole are slidably connected up and down, so that the lifting and lowering of the weighing plate 110 after bearing the weight is smoother.

[0036] As for the load cell 120 , the load cell 120 is disposed between the base frame 100 and the weighing plate 110 .

[0037] It can be understood that when the weighing plate 110 carries an object to be weighed, the weighing plate 110 presses the weighing sensor 120 downward, so that the weighing sensor 120 can weigh the object to be weighed.

[0038] As for the display 130 , the display 130 is electrically connected to the weighing sensor 120 , and the display 130 is used to display weight data, thereby facilitating workers to directly read the weight data of the object to be weighed from the display screen.

[0039] In some specific embodiments, a lifting frame 260 is disposed at the rear side of the base frame 100 , and the display 130 is disposed on the lifting frame 260 .

[0040] It is understandable that by setting the display 130 on the lifting frame 260, the lifting frame 260 can drive the display 130 to rise and fall, thereby facilitating the adjustment of the height of the display 130 and preventing the objects to be measured on the weighing plate 110 from blocking the display 130 and affecting the workers' reading of data on the display 130.

[0041] Furthermore, the lifting frame 260 includes a second vertical rod 270 fixed on the base frame 100, a lifting plate 280 slidably connected to the second vertical rod 270 up and down, a first screw 290 and a first motor 300 that drives the first screw 290 to rotate, the first motor 300 is fixed on the base frame 100, the first screw 290 is rotatably connected to the base frame 100, the first screw 290 is threadedly connected to the lifting plate 280, and the display 130 is installed on the lifting plate 280.

[0042] It is understandable that the first motor 300 drives the first screw rod 290 to rotate, so that the first screw rod 290 can drive the lifting plate 280 to move up and down, thereby making the height adjustment of the lifting plate 280 more convenient.

[0043] As for the buffer mechanism, the buffer mechanism is arranged on the front side of the base frame 100, and the buffer mechanism includes a buffer seat 140 horizontally slidably connected to the base frame 100, and a first spring 150 arranged between the buffer seat 140 and the base frame 100. The first spring 150 is used to drive the buffer seat 140 away from the base frame 100, and the buffer seat 140 is used to buffer the collision of the forklift.

[0044] It can be understood that when the forklift approaches the weighing device, after the forklift collides with the buffer seat 140, the buffer seat 140 retreats and compresses the first spring 150, so that the buffer seat 140 can buffer the collision of the forklift. After the worker feels the forward resistance of the forklift, he can stop the car in time to avoid the forklift from directly colliding with the weighing device, thereby reducing the risk of damaging the weighing device. When the forklift is away from the weighing device, the first spring 150 drives the buffer seat 140 to reset.

[0045] In some specific embodiments, the base frame 100 has a guide tube 160, and the buffer seat 140 includes a seat body 170 and a sliding rod 180. The guide tube 160 accommodates the sliding rod 180 to slide, and one end of the sliding rod 180 is connected to the seat body 170. The first spring 150 is sleeved on the outside of the sliding rod 180, and one end of the first spring 150 abuts against the seat body 170, and the other end of the first spring 150 abuts against the end of the guide tube 160, thereby making the movement of the buffer seat 140 smoother.

[0046] Furthermore, one end of the slide rod 180 away from the seat body 170 extends to the end of the guide tube 160 away from the seat body 170, and a limiting baffle 190 is provided at the end of the slide rod 180 away from the seat body 170. The limiting baffle 190 abuts against the end of the guide tube 160 away from the seat body 170 to limit the position, thereby preventing the first spring 150 from completely bouncing the buffer seat 140 off the base frame 100.

[0047] In some specific embodiments, at least two guide tubes 160 are provided, and at least two slide rods 180 and first springs 150 are provided correspondingly, so that the movement of the buffer seat 140 is more stable.

[0048] In some specific embodiments, a rubber pad 200 is disposed on a side of the buffer seat 140 away from the base frame 100 , and the rubber pad 200 is used to abut against a forklift, thereby preventing the buffer seat 140 from colliding and damaging the forklift.

[0049] In some specific embodiments, a sensor 210 and an alarm 220 are also provided on the buffer seat 140. The sensor 210 is used to sense the collision of the forklift with the buffer seat 140. The alarm 220 is electrically connected to the sensor 210. The alarm 220 is used to receive the sensing signal of the sensor 210 and alarm, so that the weighing device can alarm the worker in time to avoid the worker driving the forklift close to the weighing device without noticing that the forklift has collided with the buffer mechanism and causing damage to the weighing device.

[0050] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0051] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
