[0003] In the existing technology, due to the diversity of chemical experiments, the experimental apparatus used varies in size and shape, such as test tubes, beakers, evaporating dishes, etc. of different specifications;
[0004] When using experimental vessels that do not match the preset size of the experimental rack, smaller vessels are prone to wobbling in the larger support area, while larger vessels cannot be placed on the rack. This not only affects the accuracy and stability of the experimental operation, but also easily leads to damage to the vessels and even causes safety accidents. Utility Model Content
[0005] The purpose of this invention is to provide a chemical alcohol lamp experimental stand to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a chemical alcohol lamp experimental rack, including a base, a placement seat for placing an alcohol lamp is installed on one side of the top of the base, and an adjustment mechanism is installed on one side of the top of the base for fixing chemical experimental vessels of different specifications.
[0007] The adjustment mechanism includes a mounting housing fixedly installed on one side of the top of the base, and a vertical tube is connected to the top of the mounting housing, with a slider slidably installed on the surface of the vertical tube.
[0008] The mounting housing and the interior of the vertical tube are equipped with height adjustment components for adjusting the height of the slider;

[0011] Rubber pads are fixedly installed on the adjacent sides of the two clamping plates, and a second handle is fixedly installed on the end of the bidirectional screw located outside the adjusting housing.
[0012] Preferably, two rectangular holes are provided on one side of the adjusting housing, and one end of the two clamping plates passes through the rectangular holes and extends to the outside of the adjusting housing, and the clamping plates are slidably connected to the rectangular holes.
[0013] Preferably, the height adjustment component includes a sliding hole formed on the surface of the slider, and a threaded sleeve is provided inside the sliding hole. Fixing rods for fixing are fixedly installed on both sides of the threaded sleeve. A vertical screw is rotatably installed on one side of the top of the base, and the top end of the vertical screw passes through the mounting shell, the vertical tube and the threaded sleeve in sequence and is rotatably connected to the top of the inner cavity of the vertical tube. The vertical screw and the threaded sleeve are threadedly connected.
[0014] The vertical screw is mounted with a worm gear on the surface inside the mounting housing. A rotating rod is rotatably mounted on one side inside the mounting housing, with one end of the rotating rod penetrating the mounting housing and extending to the outside of the mounting housing.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-4 This utility model provides a technical solution: a chemical alcohol lamp experimental rack, including a base 1, a placement seat 2 for placing an alcohol lamp is installed on one side of the top of the base 1, and an adjustment mechanism 3 is installed on one side of the top of the base 1 for fixing chemical experimental vessels of different sizes.
[0027] The adjustment mechanism 3 includes a mounting housing 31 fixedly installed on one side of the top of the base 1, and a vertical tube 32 is connected to the top of the mounting housing 31. A slider 33 is slidably installed on the surface of the vertical tube 32.
[0028] The mounting housing 31 and the vertical tube 32 are equipped with a height adjustment component 34 for adjusting the height of the slider 33;
[0029] A mounting piece 35 for fixing chemical laboratory glassware of different sizes is installed on one side of the slider 33.
[0030] Reference Figure 1 , Figure 2 as well as Figure 3 As shown, the mounting component 35 includes an adjusting housing 351 fixedly mounted on one side of the slider 33, and a bidirectional screw 352 is rotatably mounted inside the adjusting housing 351. One end of the bidirectional screw 352 passes through the adjusting housing 351 and extends to the outside of the adjusting housing 351. Both sides of the surface of the bidirectional screw 352 are threadedly connected to movable seats 353, and one side of each movable seat 353 is fixedly mounted with a clamping plate 354. One end of each clamping plate 354 passes through the adjusting housing 351 and extends to the outside of the adjusting housing 351.
[0031] A rubber pad 355 is fixedly installed on one side of the two clamping plates 354 adjacent to each other, and a second handle 356 is fixedly installed on one end of the bidirectional screw 352 located outside the adjusting housing 351;
[0032] Two rectangular holes 357 are provided on one side of the adjusting housing 351, and one end of the two clamping plates 354 passes through the rectangular holes 357 and extends to the outside of the adjusting housing 351. The clamping plates 354 and the rectangular holes 357 are slidably connected.
[0033] In this embodiment, when placing experimental vessels of different sizes, the experimenter rotates the bidirectional screw 352 using the second handle 356, and uses the threaded connection between the bidirectional screw 352 and the moving seat 353 to drive the two moving seats 353 and the clamping plate 354 to move inward or outward synchronously, thereby adjusting the distance between the two worm gears 345. This allows the experimental vessels of different sizes to be fixed, preventing the experimental vessels from shaking during use and causing damage.
[0034] Reference Figure 2 as well as Figure 4As shown, the height adjustment component 34 includes a sliding hole 341 formed on the surface of the slider 33, and a threaded sleeve 342 is provided inside the sliding hole 341. Fixing rods 343 for fixing are fixedly installed on both sides of the threaded sleeve 342. A vertical screw 344 is rotatably installed on one side of the top of the base 1, and the top end of the vertical screw 344 passes through the mounting housing 31, the vertical tube 32, and the threaded sleeve 342 in sequence, and is rotatably connected to the top of the inner cavity of the vertical tube 32. A threaded connection is formed between the vertical screw 344 and the threaded sleeve 342. The vertical screw 344 is mounted on the surface inside the mounting housing 31 with a worm gear 345. A rotating rod 346 is rotatably mounted on one side inside the mounting housing 31, and one end of the rotating rod 346 passes through the mounting housing 31 and extends to the outside of the mounting housing 31. A worm 347 is mounted on the surface inside the mounting housing 31 with the rotating rod 346. The worm 347 and the worm gear 345 are meshed. A first handle 348 is fixedly mounted on the end of the rotating rod 346 outside the mounting housing 31.
[0035] In this embodiment, during a chemical experiment, the experimenter rotates the rotating rod 346 and the worm gear 347 using the first handle 348. The meshing connection between the worm gear 347 and the worm wheel 345 drives the vertical screw 344 to rotate. Simultaneously, the threaded connection between the vertical screw 344 and the threaded sleeve 342 drives the slider 33 to move up and down, thereby enabling the experimental apparatus installed inside the mounting part 35 to move up and down. This allows the experimenter to adjust the distance between the alcohol lamp and the experimental apparatus, further enhancing the practicality of the device.
[0036] Reference Figure 1 as well as Figure 4 As shown, both sides of the vertical tube 32 are provided with sliding grooves 349, and one end of the fixing rod 343 passes through the sliding groove 349 and extends to the outside of the vertical tube 32. The fixing rod 343 and the sliding groove 349 are slidably connected.
[0037] In this embodiment, while facilitating the up-and-down movement of the slider 33, the slider 33 can also be limited to prevent it from rotating during the lifting and lowering process.
[0038] Reference Figure 1 As shown, suction cups 4 are installed around the bottom of the base 1 to improve the stability of the base 1 when it is placed.
[0039] Working principle: When placing experimental vessels of different sizes, the experimenter rotates the bidirectional screw 352 through the second handle 356, and uses the threaded connection between the bidirectional screw 352 and the moving seat 353 to drive the two moving seats 353 and the clamping plate 354 to move inward or outward synchronously, thereby adjusting the distance between the two worm gears 345, and thus fixing the experimental vessels of different sizes.
[0040] Furthermore, during the chemical experiment, the experimenter rotates the rotating rod 346 and the worm gear 347 using the first handle 348. The meshing connection between the worm gear 347 and the worm wheel 345 drives the vertical screw 344 to rotate. While the vertical screw 344 is rotating, the threaded connection between the vertical screw 344 and the threaded sleeve 342 drives the slider 33 to rise and fall. This allows the experimental apparatus installed inside the mounting part 35 to move up and down, so that the experimenter can adjust the distance between the alcohol lamp and the experimental apparatus according to actual needs.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
