Description

Technical Field

[0001] This utility model belongs to the field of weight storage technology, specifically relating to a weight storage device for metrological testing. Background Technology

[0002] Metrological testing is a series of operations performed to ensure the accuracy and reliability of measuring equipment and processes. Weights play an extremely important role in metrological testing, serving as a standard measuring tool for measuring the mass of objects. When not in use, weights need to be stored. Most existing storage boxes have several grooves inside that match the size of the weights. By placing the weights in the grooves, minor collisions between them can be avoided. However, during the storage process, the weights may slide into the grooves. As the weights slide within the grooves, they rub against the filling blocks inside the storage box. Frequent friction can cause wear and tear on the weights, affecting their accuracy. Utility Model Content

[0003] This utility model provides a weight storage device for measurement and testing. By increasing the space between the two clamping slots, it can avoid the weights from rubbing against the slots when they enter the slots, which would cause wear and affect the accuracy. The connection between the two clamping slots and the limiting seat and the empty slot can prevent several weights from colliding.

[0004] This utility model provides the following technical solution: It includes a storage box and a lid, characterized in that: the storage box has a filling block inside, and the filling block has several empty slots of different sizes; the storage box also has a weight limiting assembly inside, which includes several limiting seats and connecting rods of different sizes; several limiting seats are located at the top of the connecting rods, and the limiting seats are slidably connected to the empty slots; the connecting rods have connecting shafts at both ends; the storage box has a movable frame outside, which is rotatably connected to two connecting shafts; sliding grooves are opened on both sides of the storage box, and the connecting shafts are slidably connected to the sliding grooves; the limiting seat includes a movable plate and two clamping slots; the two clamping slots are rotatably connected to the movable plate via an arc-shaped plate and a connecting groove; the movable plate has a groove at the top, and a spring is installed inside the groove; a movable block is installed at the top of the spring; the bottom of the two clamping slots, away from the arc-shaped plate, contacts the movable block.

[0005] The box cover has a filling block 2 inside, and the filling block 2 has several empty slots of different sizes.

[0006] Among them, the positions of several empty slots two correspond to those of several empty slots one, and the dimensions of several limiting seats match those of several empty slots one.

[0007] The filling block has a recessed groove inside, which communicates with the empty slot, and the connecting rod is slidably connected to the recessed groove.

[0008] The arc-shaped plate is slidably connected to the connecting groove, and a limiting block is provided on the arc-shaped plate.

[0009] Among them, several of the movable plates are fixedly connected to the connecting rods, and several of the connecting rods are arranged at equal intervals.

[0010] The beneficial effects of this utility model are as follows: When the two clamping slots are separated from the empty slot 1, the elastic force of the spring can cause the two clamping slots to rotate outward to an inclined state, thereby increasing the space between the two clamping slots. This avoids the situation where the weights are worn and affect the accuracy due to friction when they enter the two clamping slots. By limiting the weights with the two clamping slots and the connection between the limiting seat and the empty slot 1, it is possible to prevent several weights from colliding with each other, which is beneficial for protecting the weights during storage.

[0011] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] Please see Figures 1-7 This utility model provides the following technical solution: It includes a storage box 1 and a lid 2, characterized in that: the storage box 1 has a filling block 11 inside, and the filling block 11 has several empty slots 111 of different sizes; the storage box 1 has a weight limiting assembly 3 inside, the weight limiting assembly 3 includes several limiting seats 4 of different sizes and a connecting rod 5, the limiting seats 4 are located at the top of the connecting rod 5, the limiting seats 4 are slidably connected to the empty slots 111, the two ends of the connecting rod 5 are provided with connecting shafts 51, and the storage box 1 has a movable frame 6 on the outside. The moving frame 6 is rotatably connected to two connecting shafts 51. The storage box 1 has sliding grooves 12 on both sides. The connecting shafts 51 are slidably connected to the sliding grooves 12. The limiting seat 4 includes a movable plate 41 and two clamping grooves 42. The two clamping grooves 42 are rotatably connected to the movable plate 41 through an arc plate 414 and a connecting groove 421. The top of the movable plate 41 has a groove 411. The inside of the groove 411 is a spring 412. The top of the spring 412 has a movable block 413. The bottom of the two clamping grooves 42 is in contact with the movable block 413 on the side away from the arc plate 414.

[0021] This implementation includes a storage box 1 and a lid 2, which are rotatably connected to the storage box 1. When the weights are inside the storage box 1, the weights can be stored by placing the lid 2 on top of the storage box 1. The storage box 1 has a filling block 11 inside, which matches the size of the storage box 1. The filling block 11 has several slots 111 of different sizes, which are equidistantly arranged. The storage box 1 also has a weight limiting component 3 inside, whose height is adjustable. The weight limiting component 3 includes several limiting seats 4 of different sizes and connecting rods 5. The size of the limiting seats 4 matches the size of the filling blocks 11. Matching the connection, several limiting seats 4 are located at the top of the connecting rod 5. By adjusting the height of the connecting rod 5, the height of the limiting seats 4 can be adjusted. The limiting seats 4 are slidably connected to the empty slot 111. When the connecting rod 5 is at its lowest position, the limiting seats 4 are located inside the filling blocks 11. When the height of the connecting rod 5 increases, the limiting seats 4 slide out of the filling blocks 11. Connecting shafts 51 are provided at both ends of the connecting rod 5, and the connecting shafts 51 are fixedly connected to the connecting rod 5. A movable frame 6 is provided on the outside of the storage box 1. The movable frame 6 is rotatably connected to the two connecting shafts 51. By rotating the movable frame 6, the state of the movable frame 6 can be adjusted. When the movable frame 6 is in a vertical state, the movable frame 6 is located below the storage box 1. By pressing down on the storage box 1, its height can be lowered while the height of the limiting seat 4 remains unchanged. Slide grooves 12 are provided on both sides of the storage box 1, and the connecting shaft 51 is slidably connected to the slide grooves 12. The slide grooves 12 allow the connecting shaft 51 to simultaneously connect to the connecting rod 5 inside the storage box 1 and the movable frame 6 outside the storage box 1. The limiting seat 4 includes a movable plate 41 and two clamping grooves 42. The two clamping grooves 42 are symmetrical, and their outer diameters after alignment match the dimensions of the movable plate 41. The two clamping grooves 42 and the movable plate 41 are rotatably connected via an arc-shaped plate 414 and a connecting groove 421. The arc-shaped plate 414 is fixedly connected to the movable plate 41. The connecting groove 421 is located at the bottom of the clamping grooves 42, and the connecting groove 421 is rotatably connected to the arc-shaped plate 414. The dimensions of the curved plate 414 are matched. The connection between the curved plate 414 and the connecting groove 421 allows for a rotatable connection between the clamping groove 42 and the movable plate 41. When the clamping groove 42 rotates, its tilt angle can be adjusted. When both clamping grooves 42 are tilted, the space between them is larger, preventing external friction when the weight enters them. When the weight contacts the bottom of the two clamping grooves 42, its own weight causes both grooves to rotate inwards simultaneously. When the bottom of the clamping groove 42 is in close contact with the movable plate 41, the two grooves restrict the weight inwards, thus achieving the purpose of limiting its position. After the limiting seat 4 enters the inner side of the filling block 11…This avoids collisions between the weights. A groove 411 is formed at the top of the movable plate 41, located at the center of the storage box 1. A spring 412 is installed inside the groove 411, and is fixedly connected to the bottom of the groove 411. A movable block 413 is provided at the top of the spring 412. The bottom sides of the two clamping grooves 42, away from the arc-shaped plate 414, contact the movable block 413. The movable block 413 is fixedly connected to the top of the spring 412, and its thickness is less than the depth of the groove 411. Therefore, the movable block 413 can fully enter the groove 411. The space between the two clamping slots 42 and the empty slot 111 is increased by the spring force of the spring 412, thus allowing the clamping slots 42 to move outward and tilt. This prevents the weights from rubbing against the slots when they enter, which could cause wear and affect accuracy. The clamping slots 42 limit the weights, and the connection between the limiting seat 4 and the empty slot 111 prevents collisions between weights, thus protecting them during storage.

[0022] The inside of the lid 2 is provided with a filling block 21, and the filling block 21 has several empty slots 211 of different sizes. The filling block 21 matches the internal size of the lid 2. When the lid 2 is placed on the storage box 1, the filling block 21 will be aligned with the filling block 11.

[0023] Several empty slots 211 correspond to several empty slots 111 in position, and several limiting seats 4 match the size of several empty slots 111. When the weight is located in the limiting seat 4 and the limiting seat 4 is located inside the filling block 11, by covering the storage box 1 with the box cover 2, the top of the weight can be located inside the empty slot 211, thereby wrapping the weight in all directions.

[0024] The filling block 11 has a relief groove 112 inside, which is connected to the empty groove 111. The connecting rod 5 is slidably connected to the relief groove 112. When the height of the storage box 1 decreases, the connecting rod 5 will slide inside the relief groove 112.

[0025] The arc plate 414 is slidably connected to the connecting groove 421, and a limiting block is provided on the arc plate 414; the rotation angle of the clamping groove 42 can be limited by the arc plate 414 to avoid the situation where the rotation angle of the clamping groove 42 is too large.

[0026] Several movable plates 41 are fixedly connected to connecting rods 5, and several connecting rods 5 are arranged at equal intervals; when the height of the connecting rods 5 inside the storage box 1 changes, the height difference between the limiting seat 4 and the empty slot 111 will also increase or decrease accordingly.

[0027] The working principle and usage process of this utility model are as follows: When the movable frame 6 is in a vertical state, it is located below the storage box 1. By pressing the storage box 1 downwards, its height decreases while the height of the limiting seat 4 remains unchanged. The elastic force of the spring 412 pushes the two clamping slots 42 upwards, causing them to rotate outwards to an inclined state. This increases the space between the two clamping slots 42. When the weight enters the two clamping slots 42, it is not subjected to external friction, and the weight contacts the bottom of the two clamping slots 42. When touched, the weight's own weight causes both clamping slots 42 to rotate inward simultaneously. When the bottom of the clamping slots 42 is in close contact with the movable plate 41, the two clamping slots 42 will restrict the weight to the inside, thereby achieving the purpose of limiting the weight. Then, the movable frame 6 is rotated to the front or rear of the storage box 1, so that the height of the limiting seat 4 is lowered, allowing the limiting seat 4 to enter the inside of the filling block 11. Then, the box cover 2 is placed on the storage box 1, so that the top of the weight is located inside the empty slot 211, thus preventing several weights from colliding.
