Technical Field
[0001] This utility model relates to the field of fire protection testing technology, and in particular to a portable fire extinguisher testing box. Background Technology
[0002] Fire extinguishers are common fire-fighting equipment. According to relevant standards, every public place needs to be equipped with a corresponding number of fire extinguishers for emergencies. In reality, many fire extinguishers have not been used for a long time; and the effectiveness of fire extinguishers that have not been used for a long time cannot be directly judged, nor can the amount of effective substances inside them meet the requirements. Therefore, regular inspection of fire extinguishers is an important measure to improve fire safety.
[0003] Because different types of fire extinguishers contain different components, various instruments are needed to assist in the testing process. These instruments are typically stored in a suitcase, and the necessary instruments are simply retrieved from the suitcase during testing.
[0004] Patent document CN222075793U discloses a portable fire extinguisher testing box, comprising an upper and lower box body hinged together, a lifting plate, and a locking structure. The upper box body has a pre-drilled opening. The lifting plate is connected to the upper box body via multiple connecting structures and can be moved to a position that closes the pre-drilled opening. The locking structure is located between the lifting plate and the upper box body to restrict the movement of the lifting plate relative to the upper box body. This testing box has two states of use: first, when the lifting plate closes the pre-drilled opening, the upper and lower boxes are combined to function as a storage box; second, when the lifting plate moves upward, its surface is higher than the upper box body and serves as a tabletop, thus providing a supporting surface for testing fire extinguishers. The portable fire extinguisher testing box provided in this application eliminates the need for a folding table, ensuring both the capacity of the box and the portability of the fire extinguisher testing equipment.
[0005] When using the above technology, the following technical problems were found in the existing technology: after the existing testing box is opened, the support for the plate is not stable enough, and the plate is prone to tilting or falling over due to certain collisions or accidental touches. At the same time, it is not convenient to adjust the distance in the testing box according to the testing instruments placed inside. Therefore, a portable fire extinguisher testing box is designed to provide another technical solution to the above technical problems. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0034] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0036] Reference Figures 1-10A portable fire extinguisher testing box includes a first box 1 and a second box 2. The top of the first box 1 is hinged to the second box 2, so that the first box 1 and the second box 2 can be connected at one end by the hinge, and the other end of the first box 1 and the second box 2 can be connected and closed by a locking device obtained by prior art. A support plate 3 is slidably connected to the inside of the top of the second box 2. L-grooves are opened in the inside of both ends of the top of the support plate 3, so that the support plate 3 can be moved upward through the L-grooves, so that the support plate 3 can be separated from the second box 2 to provide planar support.
[0037] In this embodiment, the two sides of the support plate 3 can be connected to the first housing 1 by bolts, so that the support plate 3 will not detach from the second housing 2 when it is not in use.
[0038] Preferably, one end of the first box 1 and the second box 2 is provided with a movable wheel, and the other end of the first box 1 and the second box 2 is fixed with a push frame, so that when the movable wheels on the first box 1 and the second box 2 come into contact with the ground, the push frame can drive the detection box to move.
[0039] Limiting plates 5 are fixed on both sides of the bottom of the support plate 3. Supporting rods 4 are slidably connected to the inner sides of both ends of the limiting plates 5, so that the top of the supporting rods 4 can be translated and rotated within the limiting plates 5. The bottom of the supporting rods 4 is rotatably connected to the second housing 2, so that the height of the support plate 3 can be adjusted by the support of the supporting rods 4. A rotating rod 6 is provided between the two supporting rods 4 at the same end. The rotating rod 6 is rotatably connected to the supporting rods 4, so that the supporting rods 4 can be translated and rotated within the limiting plates 5 through the cylinder inside the top end, and the rotating rod 6 is rotatably connected to the cylinder inside the supporting rods 4, so that the rotation of the rotating rod 6 will not drive the supporting rods 4 to rotate.
[0040] Both ends of the outer side of the rotating rod 6 are provided with threaded grooves 7, and the two threaded grooves 7 rotate in opposite directions. The outer side of the threaded grooves 7 is threadedly connected to a displacement plate 8, and the top of the displacement plate 8 contacts the bottom of the support plate 3. This ensures that the rotation of the threaded grooves 7 will not cause the displacement plate 8 to rotate, allowing the displacement plate 8 to only move horizontally at the bottom of the support plate 3. A stop block 9 is fixed at the bottom of the displacement plate 8, and the stop block 9 is slidably connected to the limiting plate 5. This allows the movement of the displacement plate 8 to drive the movement of the limiting plate 5. When the displacement plate 8 is located inside the limiting plate 5, the support rod 4 is in an unadjustable position inside the limiting plate 5, thereby stabilizing the support plate 3.
[0041] Preferably, each of the four corners at the bottom of the first box 1 is threaded with an anti-slip post 14, which allows the anti-slip post 14 to be assembled or detached from the first box 1. At the same time, the contact between the anti-slip post 14 and the ground reduces scratches on the bottom of the first box 1 and increases the anti-slip effect of the first box 1.
[0042] Both the inner sides of the first housing 1 and the second housing 2 are slidably connected to a closing plate 10. This closing plate 10 limits the movement of the testing instruments placed inside the first housing 1 and the second housing 2, preventing the instruments from falling out when the first housing 1 and the second housing 2 are closed. Both sides of the closing plate 10 are slidably connected to first positioning plates 16. The first positioning plates 16 are slidably connected to the first housing 1 and to the second housing 2, allowing the closing plate 10 to enter the interior of either the first housing 1 or the second housing 2 via the first positioning plates 16 when it is inside the first housing 1 or the second housing 2. A first compression spring 17 is fixed between the two first positioning plates 16 and inside the closing plate 10. When the two first positioning plates 16 approach each other, the first compression spring 17 is compressed. At this time, the first positioning plate 16 is disengaged from the sliding connection of the first housing 1 or the second housing 2. A first push block 18 is fixed on the top of the first positioning plate 16. The first push block 18 is slidably connected to the closing plate 10. Thus, the first positioning plate 16 can be moved by pushing the first push block 18, and the closing plate 10 can be pulled up inside the first housing 1 or the second housing 2 through the gap between the first push block 18 and the second positioning plate 19.
[0043] In other embodiments, a rectangular groove may be provided inside the top of the closing plate 10, which makes it easier to put a hand into the rectangular groove and drive the closing plate 10 to rise.
[0044] Preferably, a first positioning groove 11 is provided inside the first housing 1 and the second housing 2 at a position corresponding to the first positioning plate 16, and the first positioning plate 16 and the first housing 1 are slidably connected through the first positioning groove 11.
[0045] Both the inner sides of the first housing 1 and the second housing 2 are evenly and slidably connected with cavity adjustment plates 12, so that the cavity adjustment plates 12 can be slidably moved inside the first housing 1 or the second housing 2 to adjust the size of the placed instruments, thus enabling the placement of instruments of different sizes. The inner sides of both sides of the cavity adjustment plates 12 are slidably connected with second positioning plates 19. The second positioning plates 19 are slidably connected to the first housing 1 and to the second housing 2, and the shape of the second positioning plates 19 is L-shaped, so that the second positioning plates 19 enter the interior of the first housing 1 or the second housing 2. At this time, the cavity adjustment plates 12 cannot be adjusted. The two second positioning plates 19 are fixed between the two second positioning plates 19 and located inside the cavity adjustment plates 12. The two second positioning plates 19 move closer together to drive the second compression spring 20 to compress, and the second positioning plates 19 are disengaged from the sliding first housing 1 or the second housing 2.
[0046] Preferably, the first housing 1 and the second housing 2 are provided with second positioning grooves 13 evenly distributed inside each other and at positions corresponding to the second positioning plate 19. The second positioning plate 19 is slidably connected to the first housing 1 and to the second housing 2 through the second positioning grooves 13.
[0047] Multiple extension posts 15 are evenly distributed on the inner side of the first housing 1. Adjacent extension posts 15 are also threaded together. The top of the extension post 15 is provided with a threaded groove. The top of the extension post 15 is threaded to the first housing 1, and the bottom of the extension post 15 is threaded to the anti-slip post 14. Thus, different numbers of extension posts 15 can be added between the anti-slip post 14 and the first housing 1 according to the unevenness of the ground.
[0048] The portable fire extinguisher testing box provided by this utility model is used as follows: When the support plate 3 is needed, the support plate 3 is pulled up through the L-groove. The rise of the support plate 3 causes the support rod 4 to move inside the limiting plate 5 with the position rotatably connected to the second box 2 as the center. This allows the tops of the two support rods 4 on the same side to move within the limiting plate 5, and the tops of the two support rods 4 on the same side to move away from each other. Then, after the support plate 3 is adjusted to an appropriate height, the rotating rod 6 is rotated between the second box 2 and the support plate 3. The rotation of the rotating rod 6 drives the two threaded displacement plates 8 to move in opposite directions through the threaded groove 7, causing the two displacement plates 8 to move away from each other. This allows the stop block 9 at the bottom of the displacement plate 8 to enter the inner side of the sliding limiting plate 5, thereby restricting the movement of the tops of the support rods 4 on the limiting plate 5, thus making the support plate 3 more stable.
[0049] When it is necessary to store testing instruments inside the first housing 1 and the second housing 2, the first housing 1 and the second housing 2 are opened, and then the first push block 18 is pushed. The movement of the first push block 18 causes the first positioning plate 16 to move, so that the first positioning plate 16 moves away from the sliding first positioning groove 11. At the same time, the two first positioning plates 16 move closer together, causing the first compression spring 17 to compress. At this time, through the misalignment of the first push block 18 inside the closing plate 10, the closing plate 10 is pulled, so that the closing plate 10 moves away from the sliding first housing 1 or the second housing 2. Then, according to the size of the testing instrument to be placed, the two second positioning plates 19 in the same cavity adjustment plate 12 are pushed at the same time, so that the two second positioning plates 19 in the same cavity adjustment plate 12 move closer together. Then, the second positioning plates 19 cause the second compression spring 20 to compress, and at the same time, the second positioning plates 19 move away from the sliding second positioning groove 13. Then, the cavity adjustment plate 12 moves inside the first housing 1 or the second housing 2, so as to store instruments of different sizes.
[0050] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it.
