Description

Technical Field

[0001] This utility model relates to a magnetic snap-fit ​​structure for a suspension mother liquor bottle used in a titration machine, belonging to the technical field of laboratory automation equipment. Background Technology

[0002] A titration apparatus is an experimental device used to analyze the content of specific chemical substances in a chemical sample. It typically consists of a burette, titrating reagent, indicator, and auxiliary equipment. In traditional titration operations, the method of fixing the suspension mother liquor bottle directly affects the titration efficiency and the accuracy of the analytical results. Current titration machines require the suspension mother liquor bottle to be fixed on a turntable, but changing the suspension mother liquor bottle is often time-consuming and laborious, leading to prolonged downtime and impacting production.

[0003] In recent years, the application of magnetic technology in laboratory equipment has been increasing. One type of magnetically operated automatic opening and closing mixing titration device uses a magnetically operated automatic opening and closing mechanism for the digestion flask and performs magnetic stirring with adjustable stirring speed. However, this device primarily focuses on the opening and closing mechanism of the digestion flask and does not offer an innovative solution for fixing the mother liquor bottle on the turntable.

[0004] In the field of magnetic snap-fit ​​technology, various magnetic snap-fit ​​designs already exist. One type of magnetic snap-fit ​​includes a male snap-fit ​​body and a female snap-fit ​​body, achieving engagement through the attraction of opposite poles between the first and second magnets. Similarly, another type of firmly engaged magnetic snap-fit ​​also employs a structure where a protrusion is inserted into a groove, the opposite poles of the first and second magnets are oppositely aligned, and the elastic snap is accommodated within the groove. However, these magnetic snap-fit ​​devices perform poorly under high-intensity, high-frequency testing environments, mainly due to the following problems: 1. Insufficient coordination between magnetic attraction and mechanical structure; Fasteners relying solely on magnetic attraction are prone to detachment in complex experimental environments. A self-priming circular magnetic fastener attempts to avoid the risk of detachment by engaging a circular fastener assembly with a semi-circular slot assembly. However, this structure still has limited resistance to centrifugal force under rotational conditions, and the centrifugal force generated during the rotation of the titration turntable will subject the suspension mother liquor bottle to a large outward force.

[0005] 2. Durability and reliability issues; The elastic components in existing magnetic clasps undergo repeated deformation during operation. Regardless of whether the material is steel, plastic, or other materials, this repeated deformation leads to fatigue, causing a decrease or even loss of elasticity. This problem is particularly pronounced in titration operations that require frequent changes of mother liquor bottles.

[0006] 3. Shortcomings of existing reagent container fixing methods; In the field of laboratory container fixing, a type of fastener for reagent cards uses a magnetic metal block and magnetic strip to achieve a secure fit between the upper and lower lids. However, this design primarily addresses planar fitting issues and is unsuitable for fixing titration turntables vertically.

[0007] Another type of snap-on medicine bottle cap uses a structure such as snaps, snap posts, and springs to fasten the cap to the bottle opening. However, this type of structure, which relies on mechanical springs, also faces the problems of elasticity decay and limited lifespan.

[0008] In summary, the existing methods for fixing the suspension mother liquor bottle in titration machines have the following main problems that need improvement: 1. Low fixation efficiency: Changing the suspension mother liquor bottle is time-consuming and labor-intensive, affecting experimental efficiency; 2. Insufficient resistance to centrifugal force: The centrifugal force generated when the turntable rotates can easily cause the mother liquor bottle to loosen; 3. Complex structure: Existing magnetic snap fasteners mostly rely on elastic structural components, which increases the complexity of the structure and the potential for failure; 4. Poor durability: Elastic elements are prone to fatigue, and magnetic elements may experience a decrease in magnetic force after long-term use; 5. Limited applicability: Most magnetic structures are designed for planar adsorption, which cannot be effectively used to fix vertical turntables.

[0009] Therefore, there is an urgent need for a magnetic snap-on structure that can meet the special requirements of fixing the suspended mother liquor bottle in a titration machine, and can take into account the stability of the fixation, the ease of operation and the long-term reliability of use. This is the technical problem that this utility model aims to solve. Utility Model Content

[0010] This invention overcomes the shortcomings of the existing technology and provides a magnetic snap-fit ​​structure for a suspension mother liquor bottle used in a titration machine to assist in fixation.

[0011] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a magnetic snap-fit ​​structure for a suspension mother liquor bottle for a titrator, including a suspension mother liquor bottle and a turntable, a plurality of suspension mother liquor bottles are arranged in a circumferential array on the turntable, a handle for fixing is provided on the side wall of the suspension mother liquor bottle, a metal piece is matched on the outside of the handle, and one end of the metal piece extends to the outside of the handle to form a plug connector; The turntable has a through hole corresponding to the position for fixing the suspension mother liquor bottle. A magnetic base is fixedly installed on the turntable outside the through hole. The magnetic base is a concave structure that protrudes outward. One end of the magnetic base has a plug hole. The plug of the metal sheet fixed on the suspension mother liquor bottle extends out of the plug hole and is attached to the turntable. The metal sheet is magnetically attracted to the concave side wall of the magnetic base.

[0012] Furthermore, the length of the handle is matched with the length of the through hole and the concave structure of the magnetic base, so that both ends of the handle can be inserted into the concave structure of the magnetic base through the through hole.

[0013] Furthermore, the metal sheet is fixed to the outside of the handle by screws.

[0014] Furthermore, the width of the metal plate connector is adapted to the width of the connector hole.

[0015] Furthermore, the through holes are rectangular through holes, and the through holes are evenly distributed in a circular array on the turntable.

[0016] Furthermore, the metal sheet is adapted to the width of the handle.

[0017] Furthermore, the handle and the metal plate are flush with the lower end.

[0018] Compared with existing technologies, this invention offers several advantages: By inserting a handle with a metal plate at an angle into the insertion hole of the magnetic base and utilizing magnetic attraction, it achieves rapid fixation and release of the suspended mother liquor bottle, significantly improving replacement efficiency. The unique design combining mechanical snap-fit ​​and magnetic attraction allows the handle to pass through the through-hole of the turntable and extend into the concave structure of the magnetic base, forming a mechanical limit. When the turntable rotates and generates centrifugal force, this mechanical structure effectively prevents the mother liquor bottle from loosening outwards, while the magnetic attraction primarily provides vertical adsorption and fixation. The combined effect of these two mechanisms results in a very secure fixation. This invention eliminates complex, fatigue-prone elastic components such as springs and latches, relying mainly on the simple combination of a metal plate, handle, and magnetic base. The structure is simple, with fewer potential failure points and high durability. This invention is specifically designed for vertical or inclined turntables, overcoming the application limitations of traditional planar adsorption structures in such scenarios.

[0029] The present invention will be further described below with reference to specific embodiments.

[0030] like Figures 1 to 8 As shown, this utility model discloses a magnetic snap-fit ​​structure for a suspension mother liquor bottle used in a titration machine, which mainly includes a suspension mother liquor bottle 1, a turntable 2, a handle 3, a metal sheet 4, a through hole 5, a magnetic base 6, and a plug hole 7.

[0031] Multiple suspension mother liquor bottles 1 are fixed to the turntable 2 in a circumferential array using the snap-fit ​​structure of this invention. Each suspension mother liquor bottle 1 has a handle 3 mounted on its side wall, and a metal plate 4 is fixed to the handle 3 by screws. One end of the metal plate 4 extends out of the handle 3, forming a connector 8.

[0032] A rectangular through hole 5 is provided on the turntable 2 for each mounting position. A magnetic base 6 is fixedly installed on the outside of the through hole 5. The magnetic base 6 has an outwardly protruding U-shaped or C-shaped concave structure and contains a permanent magnet. A plug hole 7 is provided at one end of the magnetic base 6 near the edge of the turntable 2.

[0033] During installation, the operator holds the suspension mother liquor bottle 1 and, together with the handle 3 and metal plate 4, aligns and inserts them at a certain angle into the through hole 5 on the turntable 2 and the insertion hole 7 of the magnetic base 6. Once the insertion connector 8 of the metal plate 4 has completely passed through the insertion hole 7, the bottle is lowered so that the metal plate 4 is firmly attached to the surface of the turntable 2. At this point, the magnet inside the magnetic base 6 firmly attracts the metal plate 4, thus fixing the suspension mother liquor bottle 1 onto the turntable 2. The length of the handle 3 matches the through hole 5 and the concave structure of the magnetic base 6, allowing both ends to be embedded within them, forming a mechanical constraint.

[0034] This utility model features a snap-fit ​​structure that prevents the suspended mother liquor bottle from falling off during rotation. The bottle body is equipped with a handle, which has a metal piece that can be attracted by magnetism. The extended metal piece and the suspended mother liquor bottle can be tilted at a certain angle and inserted into the notch of the magnetic base. The magnet fixes the bottle in place, thus achieving a suspended magnetic state. It does not need to be placed on a flat surface; it can be directly attached to a turntable perpendicular to the ground. Under the centrifugal force generated during the rotation of the turntable, the suspended mother liquor bottle has a large relative outward force, which, through the snap-fit, prevents the bottle from falling off.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
