Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for field power meter verification instruments, and in particular to a portable case structure for a verification instrument with wireless clamp meter storage and positioning functions. Background Technology

[0002] The portable case for wireless clamp meter calibrators is a professional integrated solution developed to meet the needs of high efficiency, accuracy, and portability in on-site power metering and testing. Through a customized internal structure, it provides dedicated storage space for the calibrator main unit, wireless current and voltage clamp meters, and test cables. Currently, most cases use foam structures with positioning slots to secure the calibrator.

[0003] The overly tight positioning slots designed to ensure transportation safety result in the need for forceful prying to remove the equipment on-site, severely impacting operational efficiency. Conversely, if the positioning becomes too loose due to wear or material fatigue, the equipment may wobble and collide inside the case, also posing a risk of damage. This contradiction makes it difficult to balance portability and safety with ease of access in the case design. Utility Model Content

[0004] Therefore, it is necessary to address the issue of the difficulty in balancing protection and ease of use in the design of the foam positioning slot in the housing, and to provide a portable housing structure for the calibrator with wireless clamp meter storage and positioning functions.

[0005] A portable case structure for a calibrator with wireless clamp meter storage and positioning functions includes: a portable storage case and a reinforced locking mechanism. A foam body is embedded inside the portable storage case, and the top of the foam body has an instrument mounting slot and a uniformly distributed wire mounting slot. In one embodiment, the reinforcing locking mechanism includes an elastic locking member fixedly connected inside the instrument mounting slot. A base plate is fixedly connected to the side end of the elastic locking member, and a movable locking strip is hinged to the top of the base plate. The vertical cross-sectional shapes of the elastic locking member and the movable locking strip are both opposite inverted L-shapes, and a spring is fixedly connected between the movable locking strip and the base plate.

[0006] In one embodiment, the elastic locking member includes a fixed locking strip fixedly connected to the side end of the base plate. The vertical cross-sectional shape of the fixed locking strip is an inverted L shape. The bottom of the fixed locking strip has an installation cavity. A guide rod is slidably connected inside the installation cavity. The bottom of the guide rod passes through the installation cavity, the instrument mounting slot and the foam body in sequence and is fixedly connected to the portable storage box. A spring is sleeved on the surface of the guide rod and contacts the installation cavity.

[0007] In one embodiment, the vertical cross-sectional shape of the guide rod is T-shaped, the vertical cross-sectional shape of the mounting cavity is inverted convex, and the maximum diameter of the guide rod disposed inside the mounting cavity is greater than the inner diameter of the opening of the mounting cavity.

[0008] In one embodiment, the cross-sectional shape of the mounting cavity and the contact area of ​​the guide rod are both rectangular and matched.

[0009] In one embodiment, the diameter of the top of the guide rod is larger than the diameter of the spring.

[0010] In one embodiment, the fixed clip is hinged with a pull ring, which is located below the opening of the instrument mounting slot.

[0011] In one embodiment, the corners of the fixed clip, the base plate, and the movable clip are all rounded.

[0012] In one embodiment, a flexible protective pad is adhered to the end of the fixed clip, the base plate, and the movable clip facing away from the instrument mounting groove. The flexible protective pad is a rubber material component.

[0013] Beneficial effects 1. The portable case structure of the calibrator with wireless clamp meter storage and positioning function described above, through the relative inverted L-shaped design of elastic locking parts and movable locking strips, combined with the automatic spring return function of the spring, realizes the instrument's quick lateral locking and convenient release. It effectively solves the problem in the background technology that the positioning slot is too tight, causing difficulty in picking up or too loose, causing damage during transportation due to shaking. It ensures efficient operation and equipment safety.

[0014] 2. By utilizing the elastic lifting function of the elastic locking component, relying on the stable guidance and continuous pressing of the guide rod and spring, and combined with the convenient lifting of the pull ring, the instrument can be easily picked up and placed without damage and adaptively locked. This solves the contradiction in the background technology where positioning is too tight and requires forceful prying, or too loose and causes collision damage, thus improving operational efficiency and transportation safety.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined Figure 1 - Figure 5 This invention describes the structure of a portable case for a calibrator with wireless clamp meter storage and positioning functions.

[0020] In one embodiment, a portable case structure for a calibrator with wireless clamp meter storage and positioning functions includes: a portable storage case 100 and a reinforced locking mechanism 300. A foam body 200 is embedded inside the portable storage case 100, and the top of the foam body 200 has an instrument mounting slot 210 and a uniformly distributed wire mounting slot 220.

[0021] The portable storage case 100 is made of high-strength engineering plastic or aluminum alloy. Its structure includes: a main body, a closure and locking system, a sealing and protection system, and a carrying and transportation system. The main body consists of a lower case and an upper lid connected by high-strength hinges, forming a split-opening structure. The closure and locking system includes a push-button main lock at the front and multiple rotating side locks on both sides, ensuring reliable locking. The sealing and protection system consists of an annular sealing strip with a hollow cross-section embedded in the lower case opening and a pressure-balancing valve integrated into the case wall with a built-in microporous filter membrane, ensuring dustproof and splashproof sealing. Furthermore, the carrying and transportation system offers diverse handling options, including a cushioned carrying strap fixed to the top, a telescopic pull rod with multi-stage push-button positioning locks built into the bottom, casters embedded in the case via metal brackets, and shoulder strap attachment points on the sides.

[0022] The portable storage case 100 focuses on its portability and protective functions: when accessing internal items, the user first unlocks and opens the case's closing and locking system by rotating the side lock and pressing the main lock to open the top cover and expose the internal space. After storing items, the user closes the top cover and locks the main lock and side lock in sequence, creating a sealed environment by compressing the ring-shaped sealing strip. During transportation, users can flexibly choose to carry it with a cushioned handle, use the shoulder strap for carrying, or drag it using the telescopic rod and casters, depending on the load weight and travel requirements, to adapt to different portability needs in various scenarios.

[0023] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the enhanced locking mechanism 300 includes an elastic locking member 310 fixedly connected inside the instrument mounting slot 210. It realizes convenient loading and unloading of the instrument and adaptive clamping through the elastic lifting function. The side end of the elastic locking member 310 is fixedly connected to a base plate 320, which serves as a bearing base to provide stable support for the instrument. The top of the base plate 320 is hinged to a movable locking strip 330 through a stainless steel pin. The pin passes through the lug on the base plate 320 and the shaft hole corresponding to the root of the movable locking strip 330. The vertical cross-sectional shape of the elastic locking element 310 and the movable locking strip 330 is an inverted L-shape. A spring piece 340 is fixedly connected between the movable locking strip 330 and the base plate 320. The spring piece 340 is a rectangular stainless steel leaf spring. One end of the spring piece is fixed to the base plate 320 by a screw, and the other end is freely supported on the inside of the movable locking strip 330, so that the movable locking strip 330 can automatically rebound to achieve rapid lateral locking of the instrument. A flexible protective pad 350 is glued to the end of the fixed locking strip 311, the base plate 320 and the movable locking strip 330 facing away from the instrument mounting groove 210. The flexible protective pad 350 is a rubber component and is fixed by aging-resistant acrylic pressure-sensitive adhesive, which effectively prevents the instrument surface from being scratched or bumped during the process of taking it out and locking it.

[0024] like Figure 3 , Figure 4 and Figure 5 As shown, the elastic locking component 310 includes a fixed locking strip 311 fixedly connected to the side of the base plate 320. The vertical cross-sectional shape of the fixed locking strip 311 is an inverted L-shape. The bottom of the fixed locking strip 311 has an installation cavity 312. A guide rod 313 is slidably connected inside the installation cavity 312. Its T-shaped cross-section matches the inverted convex cross-section of the installation cavity 312 to ensure a smooth and vertical lifting process and prevent detachment. The bottom of the guide rod 313 passes through the installation cavity 312, the instrument mounting groove 210 and the foam body 200 in sequence, and is fixedly connected to the lower box of the portable storage box 100 by threads. A spring 314 is sleeved on the surface of the guide rod 313 and contacts the installation cavity 312. The spring 314 is in a pre-compressed state, and its upper and lower ends abut against the top wall of the installation cavity 312 and the inner wall of the lower box of the portable storage box 100, respectively, providing continuous downward pressure so that the instrument can adaptively press and retract into the groove, effectively preventing shaking during transportation.

[0025] The guide rod 313 has a T-shaped vertical cross-section, while the mounting cavity 312 has an inverted convex vertical cross-section. The maximum diameter of the guide rod 313 inside the mounting cavity 312 is larger than the inner diameter of the opening of the mounting cavity 312. This structure ensures reliable connection and limit movement of the lifting mechanism. The cross-sectional shapes of the contact parts between the mounting cavity 312 and the guide rod 313 are both matching rectangles, effectively preventing rotation of the mechanism during lifting and achieving precise positioning. The diameter of the top of the guide rod 313 is larger than the diameter of the spring 314. Spring 314 provides a stable upper support surface, ensuring smooth compression and rebound. Fixed locking bar 311 is hinged with pull ring 315, which is located below the opening of instrument mounting slot 210, providing users with a convenient point of force application. The mechanism can be raised outside the case with a simple lifting action, replacing the traditional laborious prying and improving operational efficiency. The corners of fixed locking bar 311, base plate 320 and movable locking bar 330 are all rounded to further prevent sharp corners from causing accidental damage to the instrument and improve safety during use.

[0026] Working principle: When it is necessary to store the instrument, first open the portable storage box 100, then lift the pull ring 315. The pull ring 315, together with the fixed clip 311, the base plate 320 and the movable clip 330, will move upward to the outside of the instrument mounting slot 210. Next, the movable locking strip 330 is flipped outward so that the instrument can be placed on the base plate 320 and positioned between the fixed locking strip 311 and the movable locking strip 330. After the instrument is in place, the user first releases the movable locking strip 330, and the spring 340 drives it to rotate and cooperate with the fixed locking strip 311 to elastically lock the instrument and achieve stable fixation. Then, the pull ring 315 is released, and the spring 314 releases pressure. Guided by the mounting cavity 312 and the guide rod 313, the entire reinforced locking mechanism 300, along with the instrument, is pushed to smoothly retract into the instrument mounting slot 210. The continuous pressure provided by the spring 314 ensures that even if the foam body 200 is worn, the instrument can be adaptively adjusted and locked to prevent shaking and collision during transportation.

[0027] When the instrument needs to be retrieved, simply reverse the above procedure: lift the upper ring 315 to raise the reinforced locking mechanism 300 to the outside of the instrument mounting slot 210, then flip and open the movable locking strip 330 to easily remove the instrument. The rounded corners of the fixed locking strip 311, the base plate 320, and the movable locking strip 330, as well as the flexible protective pads 350 at their ends, prevent scratches on the instrument surface during the entire retrieval and placement process, providing protection.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
