Description

Technical Field

[0001] This invention belongs to the technical field of chemical experimental apparatus, specifically an adjustable support for chemical experiments. Background Technology

[0002] In chemical experiments, supports are frequently used to hold various containers in place. When using supports to hold chemical containers, it is sometimes necessary to adjust the height of the support. Therefore, supports are usually designed with threaded structures, where the threaded posts are used to hold the support posts in place after adjustment. However, the support posts of existing supports are typically made of metal with a smooth surface, relying solely on the friction between the threaded posts and the support posts for fastening. This can easily cause the support to slip, leading to the containers on the support tipping over or breaking. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable support for chemical experiments to solve the problems mentioned in the background art.

[0004] Therefore, one objective of this utility model is to provide an adjustable support for chemical experiments. By setting a fixing groove and a retractable fixing column, after the height of the support is adjusted, the spring pushes the fixing column into the fixing groove, which can make the support more secure.

[0005] To achieve the above objectives, the first aspect of this utility model provides an adjustable support for chemical experiments, comprising: a support body, a placement rack, and adjustment components; wherein, the placement rack is slidably connected to the support body, and the adjustment components are respectively disposed on the corresponding placement racks, the adjustment components comprising a limiting tube, a fixing post, a connecting piece, and a spring; wherein, the limiting tube is fixedly connected to the placement rack, the fixing post is slidably connected to the limiting tube, and the other end of the fixing post penetrates through the outer wall of the placement rack, the connecting piece is fixedly connected to the fixing post, the spring is sleeved on the outside of the limiting tube, and both ends of the spring are fixedly connected to the connecting piece and the placement rack respectively, and a fixing groove is provided on the support body.

[0006] In addition, the adjustable support for chemical experiments proposed above according to this utility model may also have the following additional technical features: Specifically, the rack has connection holes and the connecting piece has a pull ring.

[0007] Specifically, the main body of the support structure includes a base plate and support columns; wherein the support columns are fixedly connected to the base plate.

[0008] Specifically, a counterweight assembly is provided on the base plate; the counterweight assembly includes a limiting block, a water tank, an inlet pipe, an outlet pipe, and a pipe plug; the limiting blocks are fixed on the base plate, the water tank is installed on the base plate and is slidably connected to the corresponding limiting block, the inlet pipe and the outlet pipe are installed on the water tank, and the pipe plugs are installed on the inlet pipe and the outlet pipe, respectively.

[0009] Specifically, the bottom of the base plate is fixedly connected to support legs.

[0010] Specifically, anti-slip pads are installed on the bottom of each support leg.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This utility model adopts a spring self-locking height adjustment structure. Equidistant fixing slots are set on the support column. The retractable fixing column and the built-in spring achieve quick locking: when adjusting the height, the fixing column is stretched to disengage from the slot. After being released, the spring automatically pushes it into the corresponding fixing slot to achieve rigid locking. This ensures that the bracket can be firmly fixed at any height and prevents the container from tipping over or breaking due to the bracket slipping during operation.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0015] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings; wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] An adjustable support for chemical experiments according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0017] like Figures 1-5 As shown, an adjustable support for chemical experiments includes: a support body 1, a placement rack 2, and an adjustment component 3.

[0018] The placement rack 2 is slidably connected to the support body 1, and the adjustment components 3 are respectively set on the corresponding placement rack 2.

[0019] The adjustment assembly 3 includes a limit tube 32, a fixing post 33, a connecting piece 34, and a spring 35.

[0020] The limiting tube 32 is fixedly connected to the placement frame 2, the fixing column 33 is slidably connected to the limiting tube 32, and the other end of the fixing column 33 penetrates the outer wall of the placement frame 2. The connecting piece 34 is fixedly connected to the fixing column 33. The spring 35 is sleeved on the outside of the limiting tube 32, and the two ends of the spring 35 are fixedly connected to the connecting piece 34 and the placement frame 2 respectively. The bracket body 1 is provided with a fixing groove 37, the placement frame 2 is provided with a connecting hole 31, and a pull ring 36 is installed on the connecting piece 34.

[0021] The main body of the support frame 1 includes a base plate 11 and a support column 12.

[0022] The support column 12 is fixedly connected to the base plate 11.

[0023] Specifically, when the height of the placement rack 2 needs to be adjusted, first pull the pull ring 36, which drives the fixing post 33 to slide in the limiting tube 32 through the connecting piece 34. The spring 35 will be stretched as the fixing post 33 moves. After the fixing post 33 is completely disengaged from the fixing groove 37, move the placement rack 2 up and down so that the support post 12 slides in the connecting hole 31. When the placement rack 2 is adjusted to a suitable height, release the pull ring 36. The fixing post 33 is pushed into the corresponding fixing groove 37 under the reset force of the spring 35, thereby fixing the placement rack 2. The snap-on fixing method is more stable.

[0024] In one embodiment of this utility model, such as Figure 3 As shown, a counterweight assembly 4 is provided on the base plate 11.

[0025] The counterweight assembly 4 includes a limiting block 41, a water tank 42, an inlet pipe 43, an outlet pipe 44, and a pipe plug 45.

[0026] The limiting blocks 41 are fixed on the base plate 11, the water tank 42 is installed on the base plate 11, and the water tank 42 is slidably connected to the corresponding limiting blocks 41. The inlet pipe 43 and the outlet pipe 44 are installed on the water tank 42, and the pipe plugs 45 are installed on the inlet pipe 43 and the outlet pipe 44, respectively.

[0027] When it is necessary to increase the weight of the base plate 11, first open the pipe plug 45 on the water inlet pipe 43, then inject enough water into the water tank 42 through the water inlet pipe 43, and then close the pipe plug 45. The increased weight can prevent the placement rack 2 from collapsing. When it is necessary to drain the water in the water tank 42, open the pipe plug 45 on the water outlet pipe 44.

[0028] In one embodiment of this utility model, such as Figure 4 As shown, a support leg 5 is fixedly connected to the bottom of the base plate 11, and an anti-slip pad 6 is installed on the bottom of each support leg 5.

[0029] It should be noted that the support leg 5 described in this embodiment can support the entire chemical experiment stand, and the anti-slip pad 6 can increase the friction between the support leg 5 and the tabletop, preventing the stand from sliding during use.

[0030] Working principle: When the height of the placement rack 2 needs to be adjusted, first pull the pull ring 36. The connecting piece 34 drives the fixing post 33 to slide in the limiting tube 32. The spring 35 will be stretched as the fixing post 33 moves. When the fixing post 33 is completely disengaged from the fixing groove 37, move the placement rack 2 up and down so that the support post 12 slides in the connecting hole 31. When the placement rack 2 is adjusted to a suitable height, release the pull ring 36. The fixing post 33 is pushed into the corresponding fixing groove 37 under the return force of the spring 35, thereby fixing the placement rack 2. The snap-on fixing method is more stable.

[0031] When it is necessary to increase the weight of the base plate 11, first open the pipe plug 45 on the water inlet pipe 43, then inject enough water into the water tank 42 through the water inlet pipe 43, and then close the pipe plug 45. The increased weight can prevent the placement rack 2 from collapsing. When it is necessary to drain the water in the water tank 42, open the pipe plug 45 on the water outlet pipe 44.

[0032] In summary, by setting equidistant fixing slots 37 on the support column 12, and using the retractable fixing column 33 in conjunction with the built-in spring 35, quick locking is achieved: when adjusting the height, the fixing column 33 is stretched out of the slot, and after being released, the spring 35 automatically pushes it into the corresponding fixing slot 37 to achieve rigid locking, ensuring that the bracket can be firmly fixed at any height, preventing the container from tipping over or breaking due to the bracket slipping during operation.
