[0023] The utility model will be further explained in connection with the drawings below.

[0024] As shown in the accompanying Figures 1 to 6 The high-efficiency weight adding device comprises a force adding rod 1 and a weight adding frame 2, the weight adding frame 2 can load the weight 4 onto the force adding rod 1, and then the force adding rod 1 provides the force to the force standard machine. A plurality of weight receiving seats 3 are arranged on the force adding rod 1, and the weight 4 is placed on the corresponding weight receiving seat 3 when the weight 4 is loaded onto the force adding rod 1. The weight adding frame 2 is provided with a plurality of lifting assemblies, and the plurality of lifting assemblies correspond to the plurality of weight receiving seats 3 one by one. The lifting assembly can drive the weight 4 to move up and down, so that the weight 4 moves down to the corresponding weight receiving seat 3 or moves up to be separated from the weight receiving seat 3, so as to add or subtract the weight 4 from the weight receiving seat 3. Each group of lifting assemblies is independent, so that each weight receiving seat 3 on the force adding rod 1 can independently add or subtract the weight 4.

[0025] Since the force adding rod 1 is provided with a plurality of weight receiving seats 3, and each weight receiving seat 3 can be independently added, the weight 4 is added to the weight receiving seat 3 in a non-stacked manner. Therefore, in the process of adding the weight, each weight receiving seat 3 can simultaneously add or subtract the weight 4, thereby improving the efficiency of adding the weight and enabling the weight to be more quickly added to the required mass.

[0026] The lifting assembly comprises a movable lifting plate 5, and the lifting plate 5 is located directly above the corresponding weight receiving seat 3. As shown in the accompanying Figure 6 The lifting plate 5 is annular, and a through hole 6 is arranged at the center of the lifting plate 5 and vertically opposite to the weight receiving seat 3. The weight 4 is placed on the lifting plate 5, and the weight 4 covers the through hole 6. When the lifting plate 5 moves down, the weight receiving seat 3 passes through the through hole 6 and lifts the weight 4 away from the lifting plate 5, and at this time, the weight 4 falls on the weight receiving seat 3, thereby achieving the adding of the weight. When the lifting plate 5 moves up, the lifting plate 5 lifts the weight 4 away from the weight receiving seat 3, thereby achieving the subtracting of the weight.

[0027] As shown in the accompanying Figure 4 A clamping ring 7 is arranged at the bottom of the weight 4, and a clamping groove 8 is arranged in the clamping ring 7. When the weight 4 is placed on the lifting plate 5, the clamping ring 7 falls into the through hole 6, so that the weight 4 is not easily fallen from the lifting plate 5. When the weight receiving seat 3 lifts the weight 4 away from the lifting plate 5, the weight receiving seat 3 falls into the clamping groove 8, so that the weight 4 is not easily fallen from the weight receiving seat 3. Therefore, in the process of moving the weight 4 with the lifting assembly, the risk of falling of the weight 4 is low, and the stability is good.

[0028] A hanging hole 9 is arranged at the center of the weight 4, the force adding rod 1 is correspondingly arranged in the hanging hole 9, and the diameter of the hanging hole 9 is greater than the diameter of the force adding rod 1, so that the weight 4 does not contact the force adding rod 1 in the process of moving up and down. A cutout 10 is arranged in the weight 4 and communicates with the hanging hole 9, the weight 4 can move away from the force adding rod 1 through the cutout 10, and the force adding rod 1 can move into the hanging hole 9 through the cutout 10.

[0029] As shown in the accompanying drawings Figure 5 The force bar 1 is a vertical rod, and the plurality of holders 3 on the force bar 1 are vertically distributed. The holder 3 is disc-shaped and fixed on the force bar 1. Correspondingly, the plurality of supporting plates 5 on the force frame 2 are also vertically distributed.

[0030] The force frame 2 comprises a plurality of vertical rods 11. A plurality of supporting arms 12 are connected to the supporting plate 5, and a sleeve hole 13 is formed in the supporting arm 12. The supporting arm 12 is sleeved on the vertical rod 11 through the sleeve hole 13, so that the supporting arm 12 can move up and down along the vertical rod 11. Correspondingly, the supporting plate 5 can also move up and down along the force frame 2. Through the cooperation of the sleeve hole 13 and the vertical rod 11, the supporting plate 5 is guided and limited, so that the supporting plate 5 can be kept stable during the movement up and down along the force frame 2.

[0031] The lifting assembly further comprises a telescopic driving mechanism 14 installed on the vertical rod 11. When the telescopic driving mechanism 14 telescopes, it can apply a pushing force or a pulling force to the supporting arm 12 to drive the supporting arm 12 to move up and down along the vertical rod 11. In an embodiment, the telescopic driving mechanism 14 is an electric push rod. The front end of the electric push rod is connected to the supporting arm 12. According to the actual situation, the electric push rod can be arranged above or below the supporting plate 5. When the electric push rod telescopes, it pushes or pulls the supporting arm 12 to move up and down.

[0032] As shown in the accompanying drawings Figure 6 The two supporting arms 12 on the supporting plate 5 are connected to the opposite sides of the supporting plate 5, i.e. the two supporting arms 12 on the supporting plate 5 are arranged in a straight line. The two supporting arms 12 on the supporting plate 5 are respectively provided with independent telescopic driving mechanisms 14. When the supporting plate 5 moves up and down, the telescopic driving mechanisms 14 on the two supporting arms 12 move up and down synchronously, so that the supporting plate 5 moves up and down more stably.

[0033] The force frame 2 comprises four vertical rods 11, which are respectively located at the four corners of the force frame 2. As shown in the accompanying drawings Figure 3 The supporting arms 12 on the adjacent two supporting plates 5 are staggered with each other, and the supporting arms 12 on the adjacent two supporting plates 5 are respectively sleeved on different vertical rods 11. In this way, there is a larger space between the adjacent two supporting arms 12 on the same vertical rod 11, so that the telescopic driving mechanism 14 can be installed on the vertical rod 11.

[0034] From top to bottom on the force frame 2, the mass of the weights 4 placed on each supporting plate 5 has a tendency to increase, so that the center of gravity of the entire force frame 2 is lower and the structure is more stable.

[0035] On the weight adding frame 2, every four supporting plates 5 combine to form a weight group matching unit from top to bottom, and the weights 4 in each weight group matching unit are matched according to the multiples of 1, 2, 2 and 5. For example, on the top four supporting plates 5, the weights 4 are 1g, 2g, 2g and 5g from top to bottom, so that any weight from 1g to 10g can be obtained by different matching modes, such as 1g and 2g matching to 3g, 2g and 2g matching to 4g, and so on. By the matching mode, the number of weights 4 required can be reduced.

[0036] The weight adding device of the utility model is mainly applied to the force standard machine, and when the weights 4 are added or subtracted, the multiple lifting assemblies can move synchronously, so that the multiple weight holders 3 on the force adding rod 1 can synchronously add or subtract the weights 4, thereby shortening the time of adding weights and improving the weight adding efficiency.

[0037] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the art, some improvements and refinements can be made without departing from the principle of the utility model, and these improvements and refinements should also be regarded as the protection range of the utility model.
