Description

Technical Field

[0001] This utility model relates to the technical field of experimental equipment, and more specifically, to a folding iron stand for chemical experiments. Background Technology

[0002] Iron stands are a widely used instrument in chemical experiments. They are mainly used to fix and support various instruments, such as test tubes, flasks, and beakers, for operations such as heating, titration, and filtration. An iron stand consists of two parts: a double iron ring and a base. The base is relatively stable and can be placed on the ground or a lab bench, while the double ring can be rotated and raised to accommodate experimental instruments of different sizes and shapes.

[0003] In related technologies, the uprights of most iron stands are fixedly mounted on the base, making them difficult to stack and thus taking up too much space. Therefore, we provide a folding iron stand for chemical experiments. Utility Model Content

[0004] In order to solve the problems mentioned in the background art, the present invention provides a folding iron stand for chemical experiments.

[0005] The folding iron stand for chemical experiments provided by this utility model adopts the following technical solution:

[0006] A folding iron stand for chemical experiments includes a base and a folding rod assembly, which is detachably mounted on the top of the base; several racks, which are detachably mounted in the middle of the folding rod assembly, for placing chemical equipment; and a storage unit, located at the bottom of the base, for storing the folding rod assembly.

[0007] Preferably, the folding rod assembly includes three hinged uprights, the top of the base has a threaded hole, the uprights are threaded into the threaded hole, and a limiting sleeve is threadedly connected to the middle of the uprights, the limiting sleeve being movable to the hinge point of the two uprights.

[0008] Preferably, a threaded sleeve is fixedly connected to the bottom of the base relative to the threaded hole, and the upright can be threadedly connected to the threaded sleeve.

[0009] Preferably, the placement rack includes an inverted plate, one side of which is threaded with a fastening rod, and the other side of which is fixed with a ring. The side end of the fastening rod contacts the upright to fix the ring.

[0010] Preferably, the storage component includes a U-shaped plate fixed to the center of the bottom of the base, a pair of sliding grooves are provided on the side of the U-shaped plate, and a sliding strip is slidably connected inside the two sliding grooves. An L-shaped plate is fixed between the bottoms of the two sliding strips, and the folding rod assembly is placed on the L-shaped plate.

[0011] Preferably, the groove is dovetail-shaped, and the slide bar is adapted to the groove.

[0012] Preferably, magnets are attached to the side of the L-shaped plate to increase the stability of the L-shaped plate after it is closed.

[0013] Preferably, the bottom of the base is fixedly connected to a support foot, and the bottom of the support foot is higher than the bottom of the L-shaped plate.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] By straightening the three uprights and then rotating the corresponding limiting sleeves, the limiting sleeves are moved to the hinge point of the two uprights. Finally, the uprights are threaded into the threaded holes, thus completing the assembly of the folding rod assembly on the base. When not in use, the folding rod assembly is stored in the storage compartment, which facilitates the stacking of the base. This structural design facilitates the use of iron stands in chemical experiments and reduces the waste of space when storing iron stands.

[0024] Example 1

[0025] This utility model discloses a folding iron stand for chemical experiments. (See reference...) Figures 1 to 4 A folding iron stand for chemical experiments includes a base 1 and a folding rod assembly 2, which is detachably mounted on the top of the base 1; several racks 3, which are detachably mounted in the middle of the folding rod assembly 2, for placing chemical equipment; and a storage unit 4, located at the bottom of the base 1, for storing the folding rod assembly 2. When not in use, the folding rod assembly 2 is stored in the storage unit 4, which facilitates the stacking of the base 1. When in use, the folding rod assembly 2 is assembled on the base 1 for chemical experiments.

[0026] Specifically, the folding rod assembly 2 includes three hinged uprights 200. The top of the base 1 has a threaded hole 201. The uprights 200 are threaded into the threaded hole 201. A limiting sleeve 202 is threaded into the middle of the uprights 200. The limiting sleeve 202 can move to the hinge point of two uprights 200. By straightening the three uprights 200 and then rotating the corresponding limiting sleeve 202, the limiting sleeve 202 moves to the hinge point of two uprights 200. Finally, the uprights 200 are threaded into the threaded hole 201, thus completing the assembly of the folding rod assembly 2 on the base 1.

[0027] Specifically, a threaded sleeve 203 is fixedly connected to the bottom of the base 1 at a position relative to the threaded hole 201. The upright 200 can be threadedly connected to the threaded sleeve 203. By setting the threaded sleeve 203, when the upright 200 is assembled with the threaded hole 201, the bottom end of the upright 200 can extend into the threaded sleeve 203, thereby increasing the stability of the upright 200 assembled on the base 1.

[0028] Specifically, the placement rack 3 includes an inverted plate 300. A fastening rod 301 is threaded onto one side of the inverted plate 300, and a ring 302 is fixed to the other side of the inverted plate 300. The side end of the fastening rod 301 contacts the upright 200 to fix the ring 302. To use the placement rack 3, the inverted plate 300 is moved to a suitable position in the middle of the upright 200, and then the fastening rod 301 is rotated so that the side end of the fastening rod 301 presses against the upright 200, thereby completing the assembly of the inverted plate 300. Then, chemical instruments are placed on the ring 302 to conduct chemical experiments.

[0029] Specifically, the storage component 4 includes a U-shaped plate 400 fixed to the center of the bottom of the base 1. A pair of sliding grooves 401 are provided on the side of the U-shaped plate 400. Sliding strips 402 are slidably connected inside the two sliding grooves 401. An L-shaped plate 403 is fixed between the bottoms of the two sliding strips 402. The folding rod assembly 2 is placed on the L-shaped plate 403. By pulling the L-shaped plate 403, the L-shaped plate 403 is moved out of the U-shaped plate 400. Then, the folding rod assembly 2 is placed on top of the L-shaped plate 403. Finally, the L-shaped plate 403 is pushed to complete the storage of the folding rod assembly 2.

[0030] Specifically, the slide groove 401 is dovetail shaped, and the slide bar 402 is adapted to the slide groove 401. This design can prevent the L-shaped plate 403 and the U-shaped plate 400 from falling off.

[0031] Specifically, magnets are attached to the side of the L-shaped plate 403 to increase the stability of the L-shaped plate 403 after it is closed.

The support foot 5 can prevent the bottom of the L-shaped plate 403 from contacting the outside, thereby facilitating the stretching of the L-shaped plate 403.
