[0002] Portable gas detectors are safety devices used to detect the concentration of gases in the air. They are widely used in industry, fire protection, and environmental protection. After prolonged use, these detectors typically require calibration, necessitating the use of a calibrator. The calibrator is usually placed inside a sealed container and transported to the work environment for calibration. However, prolonged placement of the calibrator in these sealed containers during transport can lead to jolting and the containers or boxes falling, causing internal vibrations. Over time, this can loosen or damage internal components, making subsequent calibration difficult and delaying gas detection work. Therefore, the calibrator has certain limitations in its use.

[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] Example 1:

[0023] Please see Figures 1 to 3 As shown, a shockproof calibration box for a portable gas detector includes an adjustment cavity 1. A box body 2 is fixedly connected to the top of the adjustment cavity 1. A box cover 3 is rotatably mounted on one side of the top of the box body 2. A placement slot is provided inside the box body 2. Two positioning slots 4 are formed on the inner bottom wall of the placement slot. A calibrator 5 is placed inside the positioning slots 4. A positioning plate 6 is fixedly connected to the middle of the inner top wall of the adjustment cavity 1. Two first movable clamps 7 are fixedly connected to both sides of the bottom of the positioning plate 6. A first movable rod 8 is hinged to the surface of the first movable clamp 7. A connecting seat 9 is fixedly connected to the bottom of the positioning plate 6. An extension cavity 10 is fixedly connected to both sides of the connecting seat 9. A guide groove 11 is formed inside the extension cavity 10. A first resistance rod is fixedly connected to one side of the inner wall of the guide groove 11. The first damping block 12 has a first damping spring 13 fixedly connected to one side, a second damping block fixedly connected to one end of the first damping spring 13, an extrusion strip 14 fixedly connected to one side of the second damping block, a positioning short rod 15 fixedly and penetrating inside the extrusion strip 14, a base plate 16 is provided below the positioning plate 6, two second movable clamps 17 are fixedly connected to both sides of the top of the base plate 16, a second movable rod 18 is hinged to the surface of the second movable clamp 17, a first rotating ring is rotatably provided on the surface of the positioning short rod 15, and the bottom end of the first movable rod 18 is fixedly connected to the surface of the first rotating ring, and a second rotating ring is rotatably provided on the surface of the positioning short rod 15, and the bottom end of the second movable rod 18 is fixedly connected to the surface of the second rotating ring.

[0024] The positioning groove 4 allows the calibrator 5 to be placed stably. The positioning plate 6 fixes the four first movable clamps 7, and the first movable rod 8 is hinged to the surface of the first movable clamp 7. The connecting seat 9 fixes the extension cavity 10 on both sides. The extension cavity 10 allows the guide groove 11 to be opened. The guide groove 11 provides a certain guiding function for the extrusion strip 14 when it moves. The first damping block 12, the second damping block and the first shock-absorbing spring 13 provide a certain shock-absorbing effect when the extrusion strip 14 moves, and the shock-absorbing effect is transmitted to the adjustment cavity 1. The base plate 16 fixes the four second movable clamps 17 on both sides of its top, and the second movable rod 18 is hinged to its surface. The positioning short rod 15 allows the first rotating ring and the second rotating ring to be rotatably set on its surface. The width of the positioning plate 6 is smaller than the width of the base plate 16 to ensure that the first movable rod and the second movable rod are staggered.

[0025] A compression chamber is fixedly connected to the middle of the top of the base plate 16. Three third damping blocks are fixedly connected to the inner bottom wall of the compression chamber. A second damping spring 20 is fixedly connected to the top of the third damping blocks.

[0026] A lower pressure plate 19 is fixedly connected to the middle of the bottom of the connecting seat 9. Three fourth damping blocks are fixedly connected to the bottom of the lower pressure plate 19, and the bottom of the fourth damping blocks is fixedly connected to the top of the second damping spring 20. The compression chamber allows the third damping block to be fixed to its inner bottom wall. The arrangement of the second damping spring 20, the third damping block, and the fourth damping block ensures that the adjusting chamber 1 and the housing 2 have a certain damping effect when the lower pressure plate 19 squeezes them.

[0027] Example 2:

[0028] Please see Figure 1 and Figure 4 As shown, a placement cavity 21 is fixedly connected to one side of the cover 3. Two first compression springs 22 are fixedly connected to the top and bottom of one side of the placement cavity 21. A pressing plate 23 is fixedly connected to the bottom of the first compression springs 22, and a rubber pad is fixedly connected to one side of the pressing plate 23. The placement cavity 21 facilitates the placement of accessories used with the calibrator 5. The first compression springs 22 provide a certain compression effect to the pressing plate 23, pressing the calibrator 5 placed inside the positioning slot 4 and keeping it fixed. The rubber pad provides some protection for the calibrator 5 after pressing, preventing scratches.

[0029] An L-shaped fixing plate 24 is fixedly connected to the top of one side of the housing 2. A pull rod 25 slides through the inside of the L-shaped fixing plate 24. The L-shaped fixing plate 24 allows the pull rod 25 to slide inside it.

[0030] One side of the pull rod 25 is fixedly connected to the extrusion plate, and a second compression spring 26 is fixedly connected to one side of the extrusion plate. One end of the second compression spring 26 is fixedly connected to the inner wall of the L-shaped fixing plate 24. The second compression spring 26 provides the pull rod 25 with a certain compressive force.

[0031] A snap-fit ​​hole 27 is provided in the center of the top of the lid 3, and one end of the pull rod 25 passes through the interior of the snap-fit ​​hole 27. The snap-fit ​​hole 27 allows the pull rod 25 to be inserted into it, thereby securing the lid 3 when closed.

[0032] The interior of the housing 2 is equipped with a handle 28 for rotation, and the surface of the handle 28 is covered with an anti-slip pad. The handle 28 and the anti-slip pad make it easier for staff to move the housing 2.

[0033] The working principle of this utility model is as follows: When the box 2 is subjected to bumps during transportation, the box 2 and the adjusting cavity 1 will shake. Subsequently, the positioning plate 6 and the connecting seat 9 will press down, causing the first movable clamp 7 to press down one end of the first movable rod 8. Then, the positioning short rod 15 will slide inside the guide groove 11. Then, the extrusion strip 14 will squeeze the first shock-absorbing spring 13, the first damping block 12 and the second damping block, so that the shaking is absorbed by the first shock-absorbing spring 13. When the connecting seat 9 presses down, it will drive the lower pressure plate 19 to squeeze the second shock-absorbing spring 20, the third damping block and the fourth damping block, so that they can play a shock-absorbing role again, ensuring... To ensure the stability of the housing 2, once it reaches the appropriate position, the operator moves the housing 2 using handle 28. After moving it to the appropriate position, the operator pulls the lever 25 outward, compressing the second compression spring 26. At this point, one end of the lever 25 disengages from the snap-fit ​​hole 27. The operator then opens the housing cover 3 and removes the calibrator 5 to calibrate the gas detector. After calibration, the calibrator 5 is placed into the positioning slot 4. The housing cover 3 is then pressed down, causing the pressing plate 23 to press down on the calibrator 5 and hold it in place. Finally, the housing cover 3 is secured using the lever 25.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
