Description

Technical Field

[0001] This utility model mainly relates to the field of titration stage technology, specifically to a combined titration stage for chemical experiments. Background Technology

[0002] In chemical experiments, the titration stand is a commonly used device for titration analysis. Currently, a typical chemical laboratory titration stand consists of a heavy white slab at the bottom, an iron rod vertically mounted on the slab, and a butterfly clamp at the top to hold the burette for titration. While this traditional structure offers good stability, it also has significant drawbacks: For example, the use of a heavy stone slab as a counterweight at the bottom results in a significant weight for the entire titration stage, making it difficult to move and transport, especially when frequent changes in experimental location are required. Furthermore, the large base of a traditional titration stage, with its fixed, non-removable iron rod, occupies considerable laboratory space during storage, hindering the tidiness and efficient use of the stage. It also limits its applicability and ease of storage, as it cannot be quickly disassembled or adjusted according to experimental needs.

[0003] It should be noted that the above content falls within the scope of technical knowledge of those skilled in the art. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

During operation, the four positioning holes are connected to the fixed feet respectively. When the two support bases rotate, damping force is provided to improve stability. The upper and lower fixed plates are rotated at a certain angle to form a cross shape. The fixed feet arranged in a cross shape provide support for the support base. Then, the bottom of the support column is installed in the insertion hole at the top of the support base, and the rotating block is installed at the top of the support column. The test tube can then be clamped by the test tube clamp at the end of the support beam, which facilitates subsequent experiments.

When not in use, it can be rotated and stored into a straight structure, occupying little space. The top support column and rotating block are also detachable structures, which facilitates quick storage, reduces the experimental space occupied, and promotes the cleanliness and efficient use of the experimental table. No heavy stone slabs are used as counterweights, making the overall structure lighter and easier to move.

[0006] Furthermore, the fixed foot includes a threaded block, the top of which is provided with an installation block, the installation block is inserted into the positioning hole at the top, and the bottom of the threaded block is threadedly connected to a load-bearing foot.

[0007] Furthermore, the mounting block is a threaded post, threadedly connected to the positioning hole, and the top of the insertion hole is threadedly connected to the support post.

The storage box has threaded holes at its four corners, and the threaded holes are connected to the protective cover by screws.

[0010] Furthermore, the first storage slot has symmetrical concave gripping slots on both sides.

[0011] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: This utility model has a reasonable design. Through its modular and detachable design, the titration table can be quickly assembled and stored, greatly reducing the space occupied and improving the utilization rate of the laboratory tabletop.

[0012] The design employs a cross-shaped support base and adjustable height fixed feet, ensuring stability while avoiding the use of traditional heavy stone slab counterweights, making the overall structure lighter and easier to move.

[0022] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0023] See attached document Figure 1-3 A combined titration stand for chemical experiments includes two rotatably connected support bases 1. The support bases 1 have symmetrically arranged fixing plates 2 on both sides. The fixing plates 2 have positioning holes 3 at their ends, and the bottom of the positioning holes 3 is connected to fixing feet 4. The support bases 1 have insertion holes 5 at their top, and the top of the insertion holes 5 is connected to a support column 6. The top of the support column 6 is connected to a rotating block 7. The rotating block 7 has symmetrically arranged support beams 8, and the ends of the support beams 8 are provided with test tube clamps 9. In this embodiment, all structures of this application are detachable, making it easy to store in a small space. During operation, the four positioning holes 3 are connected to the fixed feet 4 respectively. When the two support bases 1 rotate, damping force is provided to improve stability. The upper and lower fixed plates 2 are rotated at a certain angle to form a cross shape. The fixed feet 4 arranged in a cross shape provide support force for the support bases 1. Then, the bottom of the support column 6 is installed in the insertion hole 5 at the top of the support base 1, and the rotating block 7 is installed on the top of the support column 6. The test tubes can then be clamped by the test tube clamp 9 at the end of the support beam 8, which facilitates subsequent experiments. This device provides stable support force for the entire device through the fixed feet 4 arranged in a cross shape, which has good stability. When not in use, it can be rotated and stored into a straight structure, which occupies little space. The top support column 6 and rotating block 7 are also detachable structures, which facilitate quick storage, reduce the experimental space occupied, and promote the cleanliness and efficient use of the experimental table. No heavy stone slabs are used as counterweights, and the overall structure is relatively light and easy to move.

[0024] The fixed foot 4 includes a threaded block 41, and the top of the threaded block 41 is provided with a mounting block 42. The mounting block 42 is inserted into the positioning hole 3 at the top. The bottom of the threaded block 41 is threadedly connected to a load-bearing foot 43. In this embodiment, the load-bearing foot 43 is divided into high and low feet, which are respectively connected to the corresponding threaded blocks 41, thereby ensuring that the support base 1 is in a horizontal state and providing support. Furthermore, the bottom load-bearing foot 43 can rotate on the threaded block 41 to finely adjust its height and adjust the horizontal state of the support base 1.

[0025] The mounting block 42 is a threaded post that is threaded to the positioning hole 3. The top of the insertion hole 5 is threaded to the support post 6. In this embodiment, the threaded block 41 can be threaded to the top positioning hole 3. Compared with the insertion method, the threaded connection is more stable. The support post 6 and the insertion hole 5 also use the insertion hole 5 to improve stability.

[0026] The top of the rotating block 7 has a concave groove, and a spirit level 71 is inserted into the concave groove. The level of the rotating block 7 can be observed through the spirit level 71. When necessary, the level of the device can be ensured by raising and lowering the fixed feet 4 at the bottom.

[0027] The device also includes a storage box 10. The storage box 10 has a first storage block 101 on its side, with four first storage slots 102. Each first storage slot 102 is adapted to a fixed foot 4. A second storage block 103 is also provided on the side of the first storage block 101, with multiple second storage slots 104. These second storage slots 104 are used to store the support base 1, support column 6, and rotating block 7. The storage box 10 has threaded holes 105 at its four corners, which are connected to a protective cover 106 via screws. In this embodiment, to improve storage efficiency and protect the device, a storage box 10 is provided. When the device is not in use for an extended period, the fixed foot 4, support base 1, support column 6, rotating block 7, and other components are stored in their respective storage slots, and the protective cover 106 is then tightened with screws.

[0028] The first storage slot 102 has symmetrical concave gripping slots 107 on both sides, which facilitate the placement and removal of the fixed feet 4.

[0029] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
