Description

Technical Field

[0001] The utility model relates to the technical field of weight storage boxes, in particular to a test weight storage box. Background Art

[0002] Weights are often used in the process of physics teaching. Weights are standard measuring tools for transferring mass values. Weights vary in size and each has a certain weight. Weights are generally stored in weight storage boxes.

[0003] The utility model patent application document with publication number "CN214325738U" discloses a weight storage box, which is mainly composed of a storage box body, an upper cover, a buckle, a sponge pad, a weight drop protection device, an elastic buffer and a weight protection pressure piece. The technical solution adopts a weight protection pressure piece to be squeezed on the upper end of the weight, and the rubber layer fits the upper end of the weight to prevent the weight from moving during vibration and prevent the weight from colliding with the inner wall of the box body during carrying and shaking. It is arranged on the outside of the storage box body and is laid on the operating table through the unfolded rubber sheet, which can increase the protection area. When the weight falls accidentally, it provides certain protection to prevent the weight from being bumped and worn.

[0004] The weight storage box disclosed in the above document has the following defects: the storage box body of the weight storage box is fixed to the upper cover by a buckle, however, after long-term use, the connection between the buckle and the upper cover may be worn, thereby causing the connection between the storage box body and the upper cover to loosen. When the handle is pulled, it is likely to cause the upper cover and the storage box body to separate, causing the weights in the sponge pad to fall out, resulting in the loss of the weights.

[0005] It can be seen from this that the storage box and the upper cover of the existing weight storage box do not have a good fixing component, and it is necessary to improve the existing shortcomings and provide a test weight storage box. Utility Model Content

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1 - Figure 5 As shown, the present invention is a test weight storage box, including a storage box body 1. An upper cover 2 is arranged on the upper surface of the storage box body 1. A first connection block 201 is arranged on the outer surface of the upper cover 2. A second connection block 101 is arranged on the outer surface of the storage box body 1. Mounting holes 3 are opened on the upper surfaces of the first connection block 201 and the second connection block 101. A fixing component 4 is installed inside the mounting hole 3. A buffer component is arranged on the inner bottom of the storage box body 1. A moisture-proof box 5 is arranged on the upper surface of the buffer component. A sponge block 6 is installed inside the moisture-proof box 5. A placement groove is opened on the upper surface of the sponge block 6. A weight body 7 is installed inside the placement groove;

[0028] When storing weights, first place the weight body 7 in the placement groove that matches it. After placing it, close the upper cover 2 and the storage box body 1 so that the first connection block 201 and the second connection block 101 are in contact with each other, and at the same time, the mounting hole 3 of the first connection block 201 is aligned with the mounting hole 3 of the second connection block 101;

[0029] The fixing component 4 includes a limiting block 401. An installation block 402 is provided on the lower surface of the limiting block 401. The installation block 402 is fitted and installed inside the limiting block 401. The outer surface of the limiting block 401 abuts against the outer surface of the first connecting block 201. A through hole 403 is formed on the outer surface of the installation block 402. A groove is formed on the inner surface of the through hole 403. A first connecting rod 404 is installed inside the groove. Two first sliders 405 are slidably connected to the outer surface of the first connecting rod 404. A first spring 406 is installed between the two first sliders 405. The first spring 406 is sleeved on the outer surface of the first connecting rod 404. A fixing block 407 is provided on the outer surface of the first slider 405. The fixing block 407 is slidably connected inside the through hole 403. The outer surface of the fixing block 407 abuts against the outer surface of the second connecting block 101;

[0030] Pick up the limiting block 401 and place the limiting block 401 directly above the installation hole 3. By pushing the limiting block 401 downward, when pushing the limiting block 401 downward, the outer surface of the fixing block 407 will abut against the inner surface of the installation hole 3. Since a slope is formed on the outer surface of the fixing block 407, this will cause the fixing block 407 to move toward the inside of the through hole 403. At the same time, the two first sliders 405 move along the axis and gradually compress the first spring 406. When the outer surface of the fixing block 407 is aligned with the outer surface of the installation block 402, at this time, the limiting block 401 can be continuously pushed downward so that the installation block 402 is fitted and installed inside the installation hole 3. When the outer surface of the limiting block 401 abuts against the outer surface of the second connecting block 101, at this time, the first spring 406 resumes its elasticity and pushes the two first sliders 405 to move outward, so that the two fixing blocks 407 move out of the through hole 403, and the outer surface of the fixing block 407 abuts against the outer surface of the first connecting block 201, completing the fixed installation between the storage box body 1 and the upper cover 2. When it is necessary to open the upper cover 2, by squeezing the two fixing blocks 407 inward, the fixing block 407 moves toward the inside of the through hole 403. When the outer surface of the fixing block 407 is aligned with the outer surface of the installation block 402, at this time, the limiting block 401 can be pulled upward so that the installation block 402 is disengaged from the inside of the installation hole 3, canceling the fixed installation between the storage box body 1 and the upper cover 2;

[0031] A telescopic rod 10 is installed on the lower surface of the upper cover 2. A contact plate 11 is installed at one end of the telescopic rod 10. The outer surface of the contact plate 11 abuts against the outer surface of the sponge block 6. A third spring 12 is sleeved on the outer surface of the telescopic rod 10. One end of the third spring 12 is installed on the lower surface of the upper cover 2, and the other end of the third spring 12 is installed on the upper surface of the contact plate 11;

[0032] After the upper cover 2 and the storage box body 1 are closed, the outer surface of the contact plate 11 will abut against the outer surface of the sponge block 6. When the storage box body 1 vibrates, it prevents the weight body 7 from moving;

[0033] The buffer assembly includes a second connecting rod 801. Two sliding grooves are provided on the lower surface of the storage box body 1. The second connecting rod 801 is installed inside the sliding grooves. The outer surface of the second connecting rod 801 is slidably connected with a second slider 802. A third connecting rod 803 is hinged to the upper surface of the second slider 802. The other end of the third connecting rod 803 is hinged to the lower surface of the moisture-proof box 5. One end of the second slider 802 is provided with a second spring 804. The other end of the second spring 804 is installed on the inner surface of the sliding groove. The second spring 804 is sleeved on the outer surface of the second connecting rod 801;

[0034] When the storage box body 1 vibrates, the moisture-proof box 5 will push the second slider 802 to slide outward on the second connecting rod 801 and gradually compress the second spring 804 through the third connecting rod 803, so as to achieve the effect of buffering the impact force;

[0035] A storage groove 202 is provided on the upper surface of the upper cover 2. A handle 9 is hinged inside the storage groove 202;

[0036] A sealing groove 102 is provided on the upper surface of the storage box body 1. A sealing block 203 is provided on the lower surface of the upper cover 2. The sealing block 203 is fitted and installed inside the sealing groove 102;

[0037] After the storage box body 1 and the upper cover 2 are closed, by using the cooperation between the sealing groove 102 and the sealing block 203, the sealing performance between the storage box body 1 and the upper cover 2 can be increased, and moisture is prevented from entering the inside of the storage box body 1.
