[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0022] See also Figures 1 to 4 In the utility model, a storage drawer in an explosion-proof safety refrigerator comprises a drawer body 1, a bearing bottom plate 2 is slidably mounted on the inner wall of the drawer body 1, a support spring 3 evenly distributed is fixedly connected to the bottom of the bearing bottom plate 2, the bottom end of the support spring 3 is fixedly connected to the inner bottom wall of the drawer body 1, a movable groove 4 is opened on the top of the drawer body 1, a limit rod 5 is slidably connected inside the movable groove 4, a synchronous gear 6 is rotatably connected to the inner wall of the movable groove 4, a tooth plate 7 is fixedly connected to the bottom of the bearing bottom plate 2, a tooth rack 8 is slidably connected to the inner wall of the movable groove 4, and a gear rack 8 is slidably connected to the inner wall of the movable groove 4. The plate 7 and the gear rack 8 are respectively located on the left and right sides of the synchronous gear 6 and are meshed with the synchronous gear 6. The top of the gear rack 8 contacts the bottom of the limit rod 5. A handle 9 is hinged on the right side of the drawer body 1. Two mounting grooves 10 are provided inside the drawer body 1. A return spring 11 is fixedly connected to the inner wall of the mounting groove 10. The other end of the return spring 11 is fixedly connected to a limit shaft 12. The limit shaft 12 passes through and extends to the outside of the drawer body 1. A connecting rope 13 is fixedly connected to the limit shaft 12. The other end of the connecting rope 13 passes through the mounting groove 10 and is connected to the handle 9.
[0023] A disc 14 is rotatably connected to the handle 9 , and one end of the connecting rope 13 located outside the mounting groove 10 is fixedly connected to the disc 14 .
[0024] A limit plate 17 is fixedly connected to the drawer body 1 , and the limit plate 17 is located on the right side of the handle 9 .
[0025] During use, the drawer body 1 is slidably connected inside the explosion-proof safety refrigerator, and a limiting hole corresponding to the limiting shaft 12 is provided on the inner wall of the refrigerator. During normal operation, the limiting shaft 12 is located inside the limiting hole to prevent the drawer body 1 from sliding. The return spring 11 supports the limiting shaft 12 so that the connecting rope 13 pulls the handle 9, and the handle 9 fits the right side of the drawer body 1. When the drawer body 1 needs to be pulled out, the user holds the handle 9 from the bottom and then rotates the handle 9. As the handle 9 rotates, the connecting rope 13 begins to move to the outside of the installation groove 10, thereby pulling the limiting shaft 12 into the interior of the installation groove 10, and the return spring 11 is forced to shrink. At this time, the limiting plate 17 limits the handle 9 so that the user can continue to exert force to pull it out. The drawer body 1 is pulled out, and then the user places the items to be stored on the top of the bearing bottom plate 2. At this time, the pressure on the top of the bearing bottom plate 2 increases and presses down the multiple groups of supporting springs 3, and the tooth plate 7 moves down accordingly, thereby pushing the synchronous gear 6 to rotate. The tooth rack 8 is on the right side of the synchronous gear 6 and then starts to move upward, pushing the limit rod 5 upward. If the weight on the top of the bearing bottom plate 2 exceeds the set value, the position of the bearing bottom plate 2 continues to drop, so that the tooth rack 8 continues to rise and pushes the limit rod 5 out of the movable groove 4. At this time, the user cannot enter the explosion-proof refrigerator when pushing the drawer body 1. If it does not exceed the set value, the user pushes the drawer body 1 in and releases the handle 9, and the reset spring 11 pushes the limit shaft 12 into the limit hole in the refrigerator to limit the drawer body 1.
[0026] In the utility model, a load-bearing bottom plate 2 supported by a supporting spring 3 is provided to store items. The height of the limit rod 5 can be changed according to the weight by cooperating with the synchronous gear 6, so that the drawer body 1 cannot be closed due to overweight, thereby prompting the user, which can effectively prevent the user from storing too many items in the drawer, thereby avoiding affecting the explosion-proof function of the drawer and improving safety. At the same time, the handle 9 can pull the limit shafts 12 on both sides to move, so as to realize automatic limiting of the drawer body 1 and reduce the possibility of accidental opening of the drawer, especially when moving or accidentally touching, further improving safety.
[0027] See also Figure 2 , wherein: evenly distributed rubber seats 15 are fixedly connected to the inner bottom wall of the drawer body 1 , and the rubber seats 15 are located at the bottom of the bearing bottom plate 2 .
[0028] In the utility model, when the top of the bearing base plate 2 is subjected to pressure, it will move downward and exert pressure on the supporting spring 3, and the rubber seat 15 can limit the bearing base plate 2 during its movement, thereby preventing heavy objects from being suddenly placed in, causing the bearing base plate 2 to press the supporting spring 3, thereby damaging the elastic force of the supporting spring 3 and affecting subsequent use.
[0029] See also Figure 4 , wherein: a guide wheel 16 is rotatably connected to the inner wall of the installation groove 10 , and the guide wheel 16 is in contact with the connecting rope 13 .
[0030] In the present invention, when the connecting rope 13 moves, the guide wheel 16 will also rotate accordingly. The arrangement of the guide wheel 16 can prevent the connecting rope 13 from rubbing against the inner wall of the installation groove 10, thereby increasing the service life of the drawer.
[0031] See also Figure 1 and 4 , wherein: a through groove is provided on the handle 9, and evenly distributed anti-slip patterns are provided on the inner wall of the through groove.
[0032] In the utility model, when the user needs to pull the handle 9, the fingers can grasp the handle 9 through the through groove, and the anti-slip pattern can prevent the user from slipping.
[0033] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
