In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0022] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0023] The following is combined with Figure 1-4 This application is described in further detail.
[0024] The embodiment of the present application discloses a laboratory iron stand, including a base 1, an iron rod 3, a small iron ring 5, a flask stand 6 and a large iron ring 7, a funnel 11 is placed on the inner side of the small iron ring 5, and support legs 10 are fixedly installed at the four corners of the bottom of the base 1. It should be noted that a support rod 51 is passed through and fixedly welded on the cross bar of the small iron ring 5, and a group of circular rings 52 are rotatably connected to the lower end of the support rod 51. A storage ring 53 is fixedly welded on the outer side of each circular ring 52. The unfolded storage ring 53 can be used to place other funnels 11 to be used, so that they can be used at any time during the experiment. It should be further noted that if the storage ring 53 is not needed, the storage ring 53 can be rotated to the bottom of the small iron ring 5 so that the small iron ring 5 and the storage ring 53 overlap each other up and down.
[0025] See also Figure 1 A U-shaped support 2 is fixedly installed on one side of the base table 1, and the iron rod 3 is rotatably connected to the inner side of the support 2 through a rotating shaft. When in use, the iron rod 3 can be rotated to a vertical state. Similarly, when not in use, the iron rod 3 can be rotated to a horizontal state; combined with Figure 2 and Figure 3As shown, a vertical positioning hole 31 and a horizontal positioning hole 32 with equal apertures are provided at the side surface of the lower end of the iron rod 3. It should be noted that a positioning knob 8 is threadedly connected to one side of the support 2, and the positioning knob 8 is aligned with the vertical positioning hole 31. When the iron rod 3 is in a vertical state, the positioning knob 8 can be tightened to insert the screw into the vertical positioning hole 31, so that the iron rod 3 is kept vertically fixed. Similarly, when the iron rod 3 is in a horizontal state, the positioning knob 8 can be tightened to insert the screw into the horizontal positioning hole 32, so that the iron rod 3 is kept horizontally fixed. It should be noted that, in order to facilitate the insertion of the screw end of the positioning knob 8 into the vertical positioning hole 31 or the horizontal positioning hole 32, a tapered guide portion 81 is provided at the screw end of the positioning knob 8. In order to make the screw of the positioning knob 8 and the positioning hole better and tightly combined, the screw diameter of the positioning knob 8 is equal to the aperture of the vertical positioning hole 31. It can be understood that in order to facilitate the horizontal placement of the iron rod 3, a rod support 9 is fixedly installed on the other side of the table top of the base 1, and the rod support 9 is aligned with the support 2. When the iron rod 3 is in contact with the rod support 9, the iron rod 3 is in a horizontal state.
[0026] Please refer again Figure 1 It should be noted that the ends of the cross bars of the small iron ring 5, the flask rack 6 and the large iron ring 7 are fixedly welded with sliding sleeves 4, and the sliding sleeves 4 are movably mounted on the iron rod 3 and can be moved up and down along the iron rod 3 to adjust the spacing between the small iron ring 5, the flask rack 6 and the large iron ring 7. It should be further noted that each sliding sleeve 4 is threadedly connected with a locking knob. When the locking knob on the sliding sleeve 4 is tightened, the end of the locking knob abuts against the iron rod 3, thereby fixing the sliding sleeve 4 and thus fixing the spacing between the small iron ring 5, the flask rack 6 and the large iron ring 7.
[0027] The implementation principle of a laboratory iron stand in the embodiment of the present application is as follows: when the iron stand needs to be used, first, the positioning knob 8 can be loosened to disengage the screw end from the horizontal positioning hole 32, thereby releasing the fixation of the iron rod 3; then, the iron rod 3 can be placed in a vertical state by rotating it, and the positioning knob 8 can be tightened to insert the screw end into the vertical positioning hole 31, thereby keeping the iron rod 3 in a vertically fixed state; then, the sliding sleeve 4 connected to the small iron ring 5, the flask stand 6, and the large iron ring 7 can be sequentially mounted on the iron rod 3, and the locking knob on the sliding sleeve 4 can be tightened to fix it after adjusting the spacing; finally, according to needs, the storage circle 53 can be rotated and expanded, and can be used to place other funnels 11 to be used, so that they can be taken at any time during the experiment, or the used funnel 11 can be temporarily placed in the storage circle 53.
[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
