[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Reference Figure 1 The utility model provides an embodiment: a nitrogen storage cabinet, including a cabinet body 1, four groups of rollers are arranged in an array at the bottom of the cabinet body 1, and the four groups of rollers are convenient for staff to move the cabinet body 1, and a cabinet door 4 is hinged on the front of the cabinet body 1, and the cabinet door 4 is symmetrically distributed in two groups. By opening the cabinet door 4, it is convenient to take or store objects in the cabinet body 1, and a stabilizing component 2 is arranged at the bottom right end of the cabinet body 1, and the stabilizing component 2 is used to improve the stability of the cabinet body 1 when it is fixed, and avoid the cabinet body 1 from being offset due to external collision, and an elastic component 3 is arranged at the bottom front end of the cabinet body 1, and the elastic component 3 is used to limit the cabinet door 4 to prevent the cabinet door 4 from automatically closing due to external influence when it is opened.
[0033] Reference Figure 1 and Figure 2The stabilizing component 2 includes a support plate 21, and a hinge rod 24 is hinged on the top of the support plate 21. The support plate 21 is driven to move vertically by the moving effect of the hinge rod 24. A movable block 25 is hinged on the top of the hinge rod 24. The movable block 25 drives the hinge rod 24 to move. A guide rod 22 is fixedly connected to the rear end of the top of the support plate 21. The guide rod 22 is fixedly connected to prevent the guide rod 22 from falling off. The outer periphery of the guide rod 22 is slidably connected to a guide block 23. The guide rod 22 and the guide block 23 guide the support plate 21 to prevent the support plate 21 from deflecting when it moves vertically.
[0034] Reference Figure 3 and Figure 4 The elastic component 3 includes a shell 31, and two groups of shells 31 are symmetrically distributed. The two groups of cabinet doors 4 are limited by the two groups of shells 31. The inner wall of the shell 31 is elastically connected with a wedge block 33 through a spring 32. Through the elastic force of the spring 32, the wedge block 33 always maintains a clamping effect with the cabinet door 4 when not affected by external force, thereby limiting the cabinet door 4.
[0035] Reference Figure 2 The bottom of the support plate 21 is fixedly connected with a rubber pad 28, and the rubber pad 28 has a certain elastic force. The bottom of the rubber pad 28 contacts the ground, thereby increasing the friction between the support plate 21 and the ground. The left side of the guide block 23 is fixedly connected to the right bottom end of the cabinet 1, and the fixing effect of the guide block 23 prevents the guide block 23 from falling off.
[0036] Reference Figure 1 and Figure 2 A fixed block 27 is fixedly connected to the bottom right end of the cabinet 1. The fixing effect of the fixed block 27 prevents the fixed block 27 from falling off. The fixed block 27 supports the threaded rod 26. The inner wall of the fixed block 27 is rotatably connected to the threaded rod 26. The outer periphery of the threaded rod 26 is threadedly connected to the inner wall of the movable block 25. The staff rotates the threaded rod 26 to drive the movable block 25 to move forward and backward along the outer periphery of the threaded rod 26.
[0037] Reference Figure 3 and Figure 4 The back of the shell 31 is fixedly connected to the bottom end of the front side of the cabinet 1, and the fixing effect of the shell 31 prevents the shell 31 from falling off. One end of the spring 32 is fixedly connected to the inner wall of the shell 31, and the other end of the spring 32 is fixedly connected to the bottom of the wedge block 33. The fixing effect of the spring 32 keeps the wedge block 33 fixed to prevent the wedge block 33 from falling off.
[0038] Reference Figure 1Two groups of support plates 21 are provided, and the two groups of support plates 21 are symmetrically distributed along the center line of the cabinet 1. By providing two groups of support plates 21, the left and right sides of the cabinet 1 are stabilized at the same time, thereby further improving the fixing effect of the cabinet 1.
[0039] Reference Figure 4 The outer wall of the wedge block 33 is slidably connected to the inner wall of the shell 31. Through the sliding effect of the wedge block 33, the wedge block 33 and the cabinet door 4 are engaged or released. The outer wall of the wedge block 33 is engaged with the outer wall of the cabinet door 4. Through the engaging effect of the wedge block 33 and the cabinet door 4, the shell 31 limits the cabinet door 4.
[0040] Reference Figure 4 One side of the wedge block 33 is a straight surface, and the other side of the wedge block 33 is a curved surface. Since one side of the wedge block 33 is a curved surface, when the cabinet door 4 is opened, the curved surface of the wedge block 33 can be squeezed, so that the wedge block 33 squeezes the spring 32 to contract. When the cabinet door 4 passes over the curved surface, the opened cabinet door 4 is limited by the straight surface of the wedge block 33.
[0041] Working principle: When the staff needs to use the nitrogen storage cabinet, the staff rotates the threaded rod 26, so that the threaded rod 26 drives the movable block 25 to move along the front direction of the cabinet body 1, thereby driving the hinge rod 24 to move, so that the support plate 21 moves upward, thereby driving the rubber pad 28 to release the contact effect with the ground, and at the same time releasing the stabilizing effect on the cabinet body 1.
[0042] The staff uses rollers to drive the cabinet body 1 to move to the specified position. After the cabinet body 1 moves to the specified position, the staff rotates the threaded rod 26 in the opposite direction, so that the threaded rod 26 drives the movable block 25 to move toward the back side of the cabinet body 1, so that the hinge rod 24 drives the support plate 21 to move downward, thereby driving the rubber pad 28 to contact the ground, increasing the contact area and friction between the cabinet body 1 and the ground, so that the cabinet body 1 remains stable.
[0043] When the staff needs to open the cabinet door 4 to take out or store items, the staff opens the cabinet door 4 and squeezes the curved surface of the wedge block 33 through the cabinet door 4, so that the wedge block 33 squeezes the spring 32, thereby causing the wedge block 33 to shrink into the shell 31. When the cabinet door 4 passes over the wedge block 33, the elastic force of the spring 32 causes the straight surface of the wedge block 33 to engage with the outer wall of the cabinet door 4, thereby limiting the opened cabinet door 4 to prevent the opened cabinet door 4 from being affected by the outside world and automatically closing. When the cabinet door 4 needs to be closed, the staff manually presses the wedge block 33 to release the engaging effect of the wedge block 33 with the cabinet door 4, thereby facilitating the staff to close the cabinet door 4.
[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
