Description
Technical Field
[0001] This utility model relates to the field of metrology equipment technology, and in particular to an embedded storage type calibration weight device. Background Technology
[0002] Measuring equipment such as electronic balances and precision scales play a vital role in scientific research, industrial production, and quality inspection. To ensure the long-term accuracy and reliability of the measurement results of these devices, they must be calibrated regularly using standard weights.
[0003] In existing technical practices, these standard weights used for calibration are usually provided as separate accessories. They are stored in a special weight box and kept separately from the main body of the measuring equipment.
[0004] However, this separate storage method brings many inconveniences. Weights require dedicated storage space and are easily forgotten, misplaced, or even lost in busy laboratory or workshop environments. Furthermore, during frequent removal, storage, and transfer, weights are easily exposed to air or touched by operators' hands, causing their surfaces to become contaminated, oxidized, or worn, which in turn affects the accuracy of their standard quality and ultimately reduces the reliability of calibration work. In addition, each calibration requires finding and opening the weight box, making the operation process relatively cumbersome.
[0005] Therefore, this invention proposes an embedded storage type calibration weight device to overcome the shortcomings of the prior art. Utility Model Content
[0006] In view of the problems of existing embedded storage calibration weight devices, such as the need for independent storage of calibration weights, easy loss and damage, cumbersome operation and low efficiency, this utility model aims to provide an embedded storage calibration weight device with an improved structure that can effectively solve the above problems.
[0007] This utility model provides an embedded storage type calibration weight device, including a shell, a tray disposed on the shell, and a weight body. The device also includes a storage mechanism disposed inside the shell for storing the weight body.
[0008] The storage mechanism is composed of multiple components, including a storage box fixedly connected to the outer shell, a movable box that can slide inside the storage box, and a protective door for closing the storage box. The movable box has a groove for accommodating the weight body, and the protective door is rotatably connected to the storage box via a hinge.
[0009] Furthermore, to ensure reliable locking, the protective door is equipped with a buckle, and the storage box is equipped with a corresponding limiting clip that cooperates with the buckle, thus forming a complete and convenient built-in weight storage system.
[0010] Preferably, to ensure that the movable box can slide stably and smoothly inside the storage box, the movable box is slidably connected to the storage box via a slide rail. This slide rail structure can provide precise guidance and effectively avoid jamming or shaking during the pulling process.
[0011] Preferably, to improve the convenience of operation, a first handle is fixedly connected to the protective door, and a second handle is fixedly connected to the movable box. These two independently set handles correspond to the opening of the protective door and the pulling action of the movable box, respectively, making the operation logic clear and allowing users to easily store and retrieve the weights.
[0012] Preferably, in order to achieve convenient locking and opening of the protective door, the limiting clamp is elastic. By utilizing the elastic deformation of its material itself, the buckle can produce a crisp confirmation and firmly hold when it is engaged, and can be easily disengaged by applying appropriate pulling force when it is opened. The structure is simple and reliable.
[0013] Preferably, the embedded storage calibration weight device also includes a quick-release structure for detachably connecting the tray to the housing. This structure allows the tray to be easily removed from the main body of the device, greatly facilitating the cleaning and maintenance of the weighing surface of the tray.
[0014] In one specific implementation, the quick-release structure includes a connecting box fixed to the lower surface of the tray, a connecting cylinder fixed inside the outer shell, and a connecting rod movably inserted inside the connecting cylinder. The connecting cylinder has an L-shaped limiting groove on its wall, and a limiting rod that can slide and engage with the L-shaped limiting groove is fixedly connected to the outer periphery of the connecting rod. By sliding and locking the limiting rod in the L-shaped limiting groove, the tray can be quickly locked and unlocked.
[0015] In a further preferred embodiment, to achieve automatic pop-out of the quick-release structure and improve the installation error tolerance, a spring is provided inside the connecting cylinder. One end of the spring is connected to the connecting cylinder, and the other end is in contact with the lower surface of the connecting rod. At the same time, a universal ball is rotatably connected inside the connecting box, and the upper end of the connecting rod is fixedly connected to the universal ball. The introduction of the universal ball allows the connecting rod to have a certain angle of deflection when rotating, making the installation process smoother.
[0016] Preferably, to facilitate the user's application of force to rotate the connecting rod to complete the locking or unlocking operation, a rotating ring is coaxially fixed on the connecting rod, which provides the user with a structure that is convenient for gripping and applying torque.
[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of existing technology where calibration weights need to be stored separately, making them easy to lose or be damaged, and calibration operations are cumbersome and inefficient. It achieves the technical effect of integrating the weights with the equipment for convenient access and effective protection of the weights to maintain their accuracy.
[0018] 2. This utility model, by adopting a quick-release structure with the coordinated action of a connecting rod, an L-shaped limiting groove and a spring, realizes the rapid installation and disassembly of the pallet, solving the problems of complex pallet connection methods and inconvenience in cleaning and maintenance in the prior art, and achieving the technical effect of simplifying operation and improving the convenience of equipment maintenance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please refer to Figures 1 to 5 This utility model provides an embedded storage type calibration weight device, which aims to solve the problems in the prior art where calibration weights need to be stored independently of the device, which makes them easy to lose or be damaged, and they need to be taken out separately before calibration, which is cumbersome and inefficient.
[0023] like Figure 1 As shown, the embedded storage type calibration weight device includes a housing 1, a tray 2 disposed on the housing 1, and a weight body 307. A storage mechanism 3 is disposed inside the housing 1 to store the weight body 307. (Refer to...) Figure 2 The storage mechanism 3 includes a storage box 301 fixedly connected to the outer shell 1. A movable box 308 is slidably connected inside the storage box 301 via a slide rail 306. The movable box 308 is provided with a groove for accommodating the weight body 307. A second handle 309 is also fixedly connected to the movable box 308 for easy pulling or pushing. The storage mechanism 3 also includes a protective door 302 rotatably connected to the lower surface of the storage box 301 via a hinge 310. A first handle 303 is fixedly connected to the protective door 302. To ensure reliable closing of the protective door 302, a buckle 305 is provided on the protective door 302. A corresponding limiting clip 304 is provided on the storage box 301 to cooperate with the buckle 305. The limiting clip 304 is elastic. When the protective door 302 is closed, the buckle 305 can elastically engage with the limiting clip 304, thereby locking the protective door 302.
[0024] Please refer to Figures 3 to 5The quick-release structure 4 includes a connecting box 401 fixed to the lower surface of the tray 2 and a connecting cylinder 402 fixed inside the outer shell 1. An L-shaped limiting groove 403 is provided on the wall of the connecting cylinder 402. The quick-release structure 4 also includes a connecting rod 407 movably inserted into the connecting cylinder 402. A limiting rod 404 is fixedly connected to the outer periphery of the connecting rod 407. The limiting rod 404 slides in conjunction with the L-shaped limiting groove 403, thereby guiding and limiting the movement trajectory of the connecting rod 407. In the assembled state, the connecting rod 407 drives the limiting rod 404 downwards along the vertical section of the L-shaped limiting groove 403 and compresses the spring 408. Then, by rotation, it enters the horizontal section, where the spring 408's rebound force achieves locking. The sliding engagement of the limiting rod 404 and the L-shaped limiting groove 403 ensures the speed of installation and the stability of the connection of the tray 2. To achieve the drive for connection and separation, a spring 408 is provided inside the connecting cylinder 402. One end of the spring 408 is connected to the connecting cylinder 402, and the other end is attached to the lower surface of the connecting rod 407 to provide an upward pushing force when unlocking. To improve the alignment flexibility during installation, a universal ball 406 is rotatably connected inside the connecting box 401. The upper end of the connecting rod 407 is fixedly connected to the universal ball 406, allowing the connecting rod 407 to tilt slightly when rotating. To facilitate user operation, a rotating ring 405 is also coaxially fixed on the connecting rod 407.
[0025] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred implementation method, refer to Figure 2 To make the sliding process of the movable box 308 within the storage box 301 smoother and more stable, the movable box 308 is slidably connected to the storage box 301 via a slide rail 306. The slide rail 306 can be a guide rail set on the inner wall of the storage box 301 and a slider that cooperates with it on the outer wall of the movable box 308. This guiding structure ensures that the movable box 308 will not get stuck or deflect during the pulling process.
[0026] As a preferred implementation method, refer to Figure 2 To facilitate the user's opening and access operations of the storage mechanism 3, a first handle 303 is fixedly connected to the protective door 302 for pulling open the protective door 302, and a second handle 309 is fixedly connected to the movable box 308 for pulling out or pushing in the movable box 308.
[0027] As a preferred implementation method, refer to Figure 2 To ensure that the protective door 302 can be securely closed and prevent accidental opening, the limiting clamp 304 is elastic, so that when the buckle 305 comes into contact with the limiting clamp 304, it can reliably engage and easily disengage by utilizing its elastic deformation.
[0028] As a preferred implementation method, refer to Figures 3 to 5 To enable the automatic unlocking and pop-out function of the quick-release structure 4 and improve the fault tolerance rate of installation alignment, a spring 408 is provided inside the connecting cylinder 402. One end of the spring 408 is connected to the connecting cylinder 402, and the other end is attached to the lower surface of the connecting rod 407. At the same time, a universal ball 406 is rotatably connected inside the connecting box 401, and the upper end of the connecting rod 407 is fixedly connected to the universal ball 406.
[0029] As a preferred implementation method, refer to Figure 3 To facilitate the user to apply torque to the connecting rod 407 to complete the locking or unlocking action of the quick-release structure 4, a rotating ring 405 is coaxially fixed on the connecting rod 407.
[0030] The working principle of this embedded storage type calibration weight device is as follows: When the weight body 307 needs to be calibrated, first pull the first handle 303. The first handle 303 drives the protective door 302 to rotate around the hinge 310 and open. During this process, the buckle 305 disengages from the elastic limit clamp 304. Then pull the second handle 309. The second handle 309 drives the movable box 308 to slide out from the storage box 301 along the slide rail 306 so as to retrieve the weight body 307 placed in the groove of the movable box 308. After the weight body 307 is used up, put it back into the movable box 308 and push the second handle 309 to make the movable box 308 slide into the storage box 301. Finally, close the protective door 302 so that the buckle 305 and the limit clamp 304 engage again, completing the safe storage of the weight body 307.
[0031] When pallet 2 needs to be installed, align the connecting box 401 fixed to the lower surface of pallet 2 with the connecting cylinder 402 inside the outer casing 1, and press down on the connecting rod 407. The connecting rod 407 drives the limiting rod 404 to slide downward along the vertical section of the L-shaped limiting groove 403 of the connecting cylinder 402, while compressing the spring 408. When the limiting rod 404 slides to the bottom of the L-shaped limiting groove 403, rotate the rotating ring 405. The connecting rod 407 rotates with the assistance of the universal ball 406, thereby driving... When the limiting rod 404 enters the horizontal section of the L-shaped limiting groove 403, the rebound force of the spring 408 presses the limiting rod 404 against the horizontal section, realizing the quick locking of the tray 2. When it is necessary to disassemble the tray 2, the rotating ring 405 is rotated in the opposite direction, so that the limiting rod 404 returns from the horizontal section of the L-shaped limiting groove 403 to the vertical section. The compressed spring 408 then rebounds, and its stored elastic energy pushes the connecting rod 407 upward, so that the entire tray 2 assembly pops upward, completing the quick disassembly.
[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
