Description

Technical Field

[0001] This utility model relates to the field of shock-absorbing transportation technology for process calibration instruments, and in particular to a storage box for process calibration instruments. Background Technology

[0002] Process calibration instruments are portable, high-precision standard instruments primarily used for measurement, calibration, and debugging in industrial process control. They can simulate or measure various process parameters, such as temperature, pressure, current, voltage, resistance, and frequency, essentially functioning as a combination of a "standard signal source" and a "high-precision measuring instrument." In automation systems, technicians use them to accurately calibrate field instruments such as transmitters, sensors, actuators, and recorders, diagnose faults, or directly simulate specific operating conditions to test system response. They are crucial tools for ensuring accurate measurement, reliable control, and efficient maintenance of production facilities.

[0003] Process calibration instruments are typically stored in traditional toolboxes during transport. In the event of accidental bumps or drops, the impact energy can easily be conducted internally, causing component displacement, damage, or reference value drift. This is especially problematic for outdoor operations requiring long-distance transport of process calibration instruments. Traditional toolboxes are heavy and inconvenient to carry, and are more susceptible to water and dust ingress. Furthermore, the instrument's control panel, display screen, and delicate wiring terminals lack adequate cushioning protection when transported alongside other tools and equipment, making them highly vulnerable to scratches, cracks, or deformation. This physical damage not only affects the appearance but can also directly lead to inaccurate measurement, malfunction, or even complete failure of the instrument, posing a threat to safety and quality control in the production process. Utility Model Content

[0004] In order to solve the problem of the fragility of process calibration instruments during transportation due to the lack of effective shock absorption and structural protection, this utility model provides a storage box for process calibration instruments to solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is:

[0006] A process calibration instrument storage box includes a box body, a storage compartment, a slide rail, a tongue-type locking mechanism, and a shock-absorbing fixing mechanism;

[0007] Several storage boxes are slidably connected in the enclosure via slide rails. Each storage box is equipped with a tongue-type locking mechanism to fix the storage box in the enclosure. The storage box is also equipped with a shock-absorbing fixing mechanism to fix the process calibration instrument.

[0008] Furthermore, the latch-type locking mechanism includes a lock box, a rotating shaft, a rocker arm, a connecting rod, and a latch;

[0009] The lock box is fixed inside the storage box. A rotating shaft is rotatably connected inside the lock box. A rocker arm is installed on the rotating shaft. A connecting rod is hinged to the upper and lower ends of the rocker arm. A tongue is hinged to the other end of the two connecting rods. The tongue slides through the lock box and the storage box in sequence and can be inserted into the inner wall of the box.

[0010] Furthermore, the front end of the storage box has an opening, and a rotating handle is installed in the opening, with the rotating handle fixedly connected to the rotating shaft.

[0011] Furthermore, the shock absorption fixing mechanism includes a transverse slide bar, a transverse clamping plate, a spring bar, and a vertical push plate;

[0012] A horizontal slide bar is provided between the left and right inner walls of the storage box. Two horizontal clamping plates are slidably connected to the horizontal slide bar. A spring is fitted on the horizontal slide bar. The spring causes the two horizontal clamping plates to tend to move closer to each other. Multiple spring rods are provided on the inner bottom wall of the storage box. A vertical push plate is fixed to the movable end of the spring rod. The spring rod causes the vertical push plate to tend to move upward.

[0013] Furthermore, the tops of both transverse clamping plates are provided with opposing limiting protrusions.

[0014] Furthermore, the front end of the storage box is provided with an extension edge, and a sealing strip is provided on the extension edge.

[0015] Furthermore, the box is equipped with a retractable pull rod.

[0016] Furthermore, the tie rod adopts a three-section tie rod design.

[0017] Furthermore, a handle is provided at the top of the box.

[0018] Furthermore, casters are installed at the four corners of the bottom of the box.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1. A process calibration instrument storage box, equipped with a shock-absorbing and fixing mechanism for shock-absorbing and fixing the process calibration instrument. The shock-absorbing and fixing mechanism has two transverse clamping plates that can slide parallel to each other on a transverse slide bar. The two transverse clamping plates are pushed closer to each other by springs, clamping the instrument body and preventing damage to the instrument from lateral vibration during transportation; at the same time, a vertical push plate is pushed upward by a spring rod, working with the transverse clamping plates to clamp and fix the instrument vertically, effectively suppressing the impact caused by vertical vibration.

[0021] 2. Equipped with a tongue-type locking mechanism and sealing strip to ensure the storage box is airtight. Rotating the handle drives the shaft to rotate, which in turn drives the rocker arm to rotate. The rocker arm, through a connecting rod, causes the tongue to extend into the inner wall of the box to lock, ensuring that the storage box will not be accidentally opened during transportation. Together with the sealing strip on the extended side, it forms a tight protection, effectively preventing dust and water damage, and improving the protection of process calibration instruments during outdoor transportation.

[0022] 3. Equipped with a pull rod and casters, it facilitates long-distance transportation and carrying of process calibration instruments during outdoor calibration operations, reducing the physical burden on users and improving mobility. The pull rod adopts a three-section structure, which can be adjusted in height according to usage needs to accommodate the pushing habits of operators of different heights.

[0033] Specific implementation method one: See Figure 1-4As shown, a process calibration instrument storage box, in this embodiment, includes a box body 1, a storage box 2, a slide rail 3, a tongue-type locking mechanism, and a shock-absorbing fixing mechanism.

[0034] Several storage boxes 2 are slidably connected in the housing 1 via slide rails 3. Each storage box 2 is equipped with a tongue-type locking mechanism, which can fix the storage box 2 in the housing 1. Each storage box 2 is also equipped with a shock-absorbing fixing mechanism, which is used to fix the process calibration instrument.

[0035] Furthermore, the shock-absorbing and fixing mechanism includes a horizontal slide bar 501, a horizontal clamping plate 502, a spring 503, and a vertical push plate 505. The front end of the housing 1 has multiple openings for accommodating storage boxes 2; in this embodiment, 2×2 storage boxes 2 are used as an example. Each opening of the housing 1 has symmetrically arranged slide rails 3 on both sides of its inner wall. The storage boxes 2 are connected to the movable ends of the slide rails 3 on both sides, allowing the storage boxes 2 to slide smoothly in and out of the housing 1 along the slide rails 3. The shock-absorbing and fixing mechanism is used to fix the process calibration instruments. It also prevents damage to the instruments from lateral and vertical vibrations during transportation. The latch-type locking mechanism is used to ensure the storage boxes 2 are closed, ensuring that the storage boxes 2 will not be accidentally opened during transportation.

[0036] Specific Implementation Method Two: See Figure 7-9 As shown, the tongue-type locking mechanism of this embodiment includes a lock box 401, a rotating shaft 402, a rocker arm 403, a connecting rod 404, and a tongue 405.

[0037] The lock box 401 is fixed inside the storage box 2. A rotating shaft 402 is rotatably connected inside the lock box 401. A rocker arm 403 is provided on the rotating shaft 402. A connecting rod 404 is hinged to the upper and lower ends of the rocker arm 403. A tongue 405 is hinged to the other end of the two connecting rods 404. The tongue 405 slides through the lock box 401 and the storage box 2 in sequence and can be inserted into the inner wall of the box 1.

[0038] Furthermore, the lock box 401 is fixed to the inner front wall of the storage box 2 by bolts. The lock box 401 has a shaft hole through which the rotating shaft 402 passes and rotates. The rocker arm 403 is perpendicular to the axis of the rotating shaft 402. Square guide holes are symmetrically provided at both ends of the lock box 401. The tongue 405 passes through the guide holes and slides with them, ensuring stable extension and retraction of the tongue in the horizontal direction. The side wall of the storage box 2 has a through hole corresponding to the guide hole. The tongue 405 extends to the outside of the storage box 2 through this through hole and can be embedded in a groove on the side wall of the box 1 to achieve locking. When the handle 407 is rotated, the handle 407 drives the rotating shaft 402 to rotate, which in turn drives the rocker arm 403 to rotate. The rocker arm 403, through a connecting rod 404, drives the tongue 405 to extend into the inner wall of the box 1 to achieve locking, ensuring that the storage box 2 will not be accidentally opened during transportation.

[0039] Specific implementation method three: See Figure 7-9 As shown, the storage box 2 of this embodiment has an opening 406 at the front end, and a rotating handle 407 is installed in the opening 406. The rotating handle 407 is fixedly connected to the rotating shaft 402.

[0040] Furthermore, the opening 406 is used to install the handle 407, so that the handle 407 is nearly flush with the front end of the storage box 2, to prevent the handle 407 from being misoperated due to external impact during transportation or handling, and to ensure the stability of the locking mechanism.

[0041] Detailed Implementation Method Four: See [link] Figure 5-7 As shown, the shock absorption fixing mechanism of this embodiment includes a horizontal slide bar 501, a horizontal clamping plate 502, a spring bar 504, and a vertical push plate 505.

[0042] A horizontal slide bar 501 is provided between the left and right inner walls of the storage box 2. Two horizontal clamping plates 502 are slidably connected to the horizontal slide bar 501. A spring 503 is fitted on the horizontal slide bar 501. The spring 503 causes the two horizontal clamping plates 502 to tend to move closer to each other. Multiple spring rods 504 are provided on the inner bottom wall of the storage box 2. A vertical push plate 505 is fixed to the movable end of the spring rod 504. The spring rod 504 causes the vertical push plate 505 to tend to move upward.

[0043] Furthermore, the transverse slide rods 501 are cylindrical rod structures. In this embodiment, a 2×2 arrangement is used as an example. The four transverse slide rods 501 are slidably connected to the four corners of the transverse clamping plate 502, ensuring that the transverse clamping plate 502 remains stable during sliding. Springs 503 are set between the transverse clamping plate 502 and the inner wall of the storage box 2, and multiple springs 503 are fitted on each transverse slide rod 501. The transverse clamping plates 502 move closer to each other through the push of the springs 503, so that the two transverse clamping plates 502 clamp the instrument body, avoiding damage to the instrument caused by transverse vibration during transportation. At the same time, the vertical push plate 505 is pushed upward under the action of the spring rod 504, which, together with the transverse clamping plates 502, achieves vertical clamping and fixation of the instrument, effectively suppressing the impact caused by vertical vibration.

[0044] Specific implementation method five: See Figure 5-7 As shown, the tops of the two transverse clamping plates 502 in this embodiment are provided with limiting protrusions 506 that are positioned opposite each other.

[0045] Furthermore, the limiting protrusion 506 is used to hold the upper edge of the instrument body. The limiting protrusion 506 and the upward-pushing vertical push plate 505 work together to form an upper and lower clamping force to prevent the instrument from loosening or shifting during transportation.

[0046] Specific implementation method six: See Figure 6As shown, the storage box 2 in this embodiment has an extension edge 507 at its front end, and a sealing strip 508 is provided on the extension edge 507.

[0047] Furthermore, the extended edge 507 fits snugly against the front opening edge of the box 1, and the sealing strip is embedded in the gap between the extended edge 507 and the box 1, fitting tightly against the front of the box 1, effectively preventing external dust and moisture from entering the interior of the storage box 2 and enhancing its protective performance.

[0048] Detailed implementation method seven: See Figure 1-4 As shown, the housing 1 of this embodiment is provided with a retractable pull rod 6.

[0049] Detailed Implementation Method Eight: See also Figure 1-4 As shown, the tie rod 6 in this embodiment is a three-section tie rod.

[0050] Detailed Implementation Method Nine: See also Figure 1-4 As shown, the upper end of the box 1 in this embodiment is provided with a handle 7.

[0051] Detailed Implementation Method Ten: See [link / details] Figure 1-4 As shown, the bottom four corners of the box 1 in this embodiment are provided with casters 8.

[0052] Furthermore, it is equipped with a pull rod 6 and casters 8, which facilitates long-distance transportation and carrying of process calibration instruments during outdoor calibration operations, effectively reducing the physical burden on users and significantly improving mobility. The pull rod 6 adopts a three-section structure design, which can be flexibly adjusted in height according to actual usage needs to accommodate the pushing habits of operators of different heights.
