Abstract
Description
Technical Field
[0001] This utility model relates to the field of weight calibration technology, and more specifically, to a shockproof buffer tray for weight calibration auxiliary. Background Technology
[0002] Weight calibration is a technical process of periodically verifying and adjusting weights that represent units of mass. It aims to ensure the accuracy of their mass values in order to measure the mass of objects and to calibrate weighing instruments. When calibrating weights by weighing, the weights need to be placed in a tray for weighing.
[0003] Traditional weight calibration auxiliary trays involve placing weights inside the tray and weighing them using a calibration scale placed underneath. However, most traditional trays lack shock-absorbing structures. When weights are placed, their large weight and the instantaneous impact force generated during placement can cause severe vibrations to the tray and the calibration scale below. This vibration can interfere with the measurement stability of the calibration equipment, leading to deviations in calibration data and reducing the reliability of calibration results.
[0004] Therefore, we have made improvements to this by proposing a shock-absorbing tray for weight calibration assistance. Utility Model Content

[0026] Example 1 Please refer to Figure 1-4A shock-absorbing tray for weight calibration assistance includes a base 1, an adjustment component 2 at the bottom of the base 1, a shock-absorbing component 3 in the inner cavity of the base 1, a placement tray 4 fixedly connected to the top of the shock-absorbing component 3, an anti-slip pad 5 in the inner cavity of the placement tray 4, multiple anti-slip grooves 6 on the surface of the anti-slip pad 5, and two mounting blocks 7 fixedly installed on both sides of the placement tray 4, with a handle 8 rotatably connected between the two mounting blocks 7. The shock absorption assembly 3 includes two limiting plates 301, which are fixedly installed on both sides of the bottom of the inner cavity of the chassis 1. Two first sliding rods 302 are slidably connected between the two limiting plates 301. The two ends of the two first sliding rods 302 pass through one side of the two limiting plates 301 and are fixedly installed with movable blocks 303. The inner cavity of the movable block 303 is slidably connected to a second sliding rod 304. A first damping spring 305 is provided on the surface of the second sliding rod 304. A first connecting block 306 is fixedly connected to one end of the second sliding rod 304. The first connecting block 306 is fixedly connected to the bottom of the inner cavity of the chassis 1. A support plate 307 is rotatably connected to one end of the first sliding rod 302. A connecting rod 309 is rotatably connected to one end of the support plate 307. A first movable rod 308 is rotatably connected to the middle of the support plate 307. The two ends of the connecting rod 309 are connected to second connecting blocks 310. The second connecting blocks 310 are fixedly connected to the bottom of the placement tray 4. A connecting plate 311 is connected to one side of the second connecting block 310. A second movable rod 312 is fixedly connected to the bottom of the connecting plate 311. A connecting column 313 is slidably connected to the bottom of the second movable rod 312. The connecting column 313 is fixedly connected to the bottom of the inner cavity of the chassis 1. A second damping spring 314 is provided in the inner cavity of the connecting column 313. A connecting groove 315 that mates with the second movable rod 312 is provided in the inner cavity of the connecting column 313.
[0027] During implementation, the handles 8 on both sides of the placement pan 4 can rotate flexibly via the mounting blocks 7. Operators can easily move the device body by gripping the handles 5, avoiding contamination or positional shift caused by direct contact with the weights. The anti-slip pad 5 inside the placement pan 4 and the anti-slip grooves 6 on its surface enhance friction through a double structure. The anti-slip pad 5 is made of highly elastic rubber and fits tightly against the bottom of the weights, increasing contact resistance. The anti-slip grooves 6 further disperse the pressure of the weights through their textured surface, creating negative air pressure to prevent the weights from sliding during vibration or slight tilting, ensuring the stability of the weights' position during calibration. When the weights are placed on the placement pan 4, the shock absorption component 3 absorbs the impact force through a multi-dimensional buffer structure. The weight's gravity causes the placement pan 4 to press down, driving the connecting... As the connecting plate 311 and the second connecting block 310 move downwards, the connecting rod 309 pushes the two side support plates 307 to slide outwards along the first slide rod 302. The movable block 303 moves synchronously along the second slide rod 304. The first damping spring 305 is compressed, and the elastic deformation of the spring converts the lateral impact force into elastic potential energy, achieving horizontal shock absorption. As the placement plate 4 moves downwards, the second connecting block 310 drives the second movable rod 312 to slide downwards along the connecting groove 315 inside the connecting column 313. The second damping spring 314 is compressed, and the vertical impact force is absorbed through longitudinal elastic deformation, forming a synergy with the lateral buffer to constitute a three-dimensional shock absorption system that combines horizontal and vertical elements, significantly reducing the instantaneous impact when the weight is placed.
[0028] Example 2 The adjustment assembly 2 includes four support columns 201, which are fixedly installed at the four corners of the bottom of the chassis 1. Threaded columns 202 are threadedly connected to the inner cavity of each support column 201, and rubber pads 203 are fixedly installed at the bottom of each threaded column 202. A mounting plate 204 is fixedly connected between two support columns 201, and a liquid level 205 is installed inside the mounting plate 204.
[0029] During implementation, the adjustment component 2 provides a horizontal reference and stable support for the device. Before use, the liquid level 205 inside the mounting plate 204 is used to determine whether the chassis 1 is level. If there is a tilt, the threaded column 202 inside the support column 201 is rotated to change the height of a single support column 201 using thread transmission until the bubble in the liquid level 205 is centered, thus achieving precise leveling of the placement plate 4. The rubber pad 203 increases the friction with the placement surface to prevent the device from sliding during load-bearing or operation, while also reducing the transmission of vibration at the bottom.
