Description

An automatic locking flask rack Technical Field

[0001] This utility model relates to the field of chemical instrument and equipment technology, specifically to an automatic locking and placing rack for flasks. Background Technology

[0002] Currently, most flask racks used in laboratories employ simple mechanical clamps, requiring repeated manual tightening and loosening. This method has two major drawbacks: first, researchers need to frequently adjust the clamp positions, which is inefficient, especially when processing multiple flasks in batches; second, the manual application of force is difficult to standardize, easily leading to flask tipping due to improper clamping, potentially causing liquid leakage or even experimental accidents. Furthermore, while existing electric clamping devices on the market can achieve automatic locking, they have significant limitations: relying on motors, gear sets, and screw transmission systems results in bulky and expensive devices, and most have fixed strokes, making them incompatible with different flask sizes and inconvenient to maintain.

[0003] In conclusion, there is an urgent need to develop a flask fixing solution that combines ease of operation, stability, and low maintenance costs. Summary of the Invention

[0004] In view of the above-mentioned technical problems in related technologies, this utility model proposes an automatic flask locking and placement rack, which can overcome the above-mentioned shortcomings of the prior art.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:

[0006] An automatic flask locking rack includes a base, and at least two support arms are provided on the upper end of the base. Each support arm is movably connected to the base through a corresponding elastic buckle assembly.

[0007] Furthermore, the base includes an upper base and a lower base arranged correspondingly on the top and bottom, and the upper base and the lower base are connected by a metal fixing column.

[0008] Furthermore, both the upper base and the lower base are annular, and the support arms are evenly spaced along the annulus of the upper base.

[0009] Furthermore, the upper part of the upper base is provided with a pair of fixing frames corresponding to the number of support arms. The upper base is provided with a corresponding snap ring interface in the middle of the pair of fixing frames. The upper base is provided with an opening between the fixing frame and the snap ring interface.

[0010] Furthermore, the upper end of the support arm is provided with a bayonet, the middle of the bayonet is provided with an adjustable screw, the lower end of the support arm is provided with a snap ring interface, and the inner side of the support arm is provided with an arc-shaped support surface for supporting the outer wall of the flask.

[0011] Furthermore, the buckle assembly includes a fixing pin and a retaining spring. The two ends of the retaining spring are respectively connected to the retaining spring interface one and the retaining spring interface two, the middle part of the retaining spring is connected to the fixing pin, and the bottom end of the support arm is connected to the corresponding fixing frame through the fixing pin.

[0012] The beneficial effects of this utility model are as follows: This utility model uses an elastic buckle assembly to set a movable support arm on the base. The support arm rotates at a certain angle due to the gravity of the flask to achieve automatic locking of the flask. When the flask is lifted upward, the support arm resets through the elastic buckle assembly to actively unlock the flask. In addition, the adjustable screw can also lock and reinforce the flask. This application is very convenient to operate, and the safety is greatly improved. It is suitable for flasks of different specifications and can flexibly adapt to various experimental needs.

[0025] As shown in Figures 1-9, an automatic flask locking and placement rack according to an embodiment of the present invention includes a base 1. At least two support arms 2 are provided on the upper end of the base 1, and each support arm 2 is movably connected to the base 1 through a corresponding elastic buckle assembly 3.

[0026] The base 1 includes an upper base 101 and a lower base 102 arranged vertically and vertically, and the upper base 101 and the lower base 102 are connected by a metal fixing post 103.

[0027] Both the upper base 101 and the lower base 102 are annular, and the support arms 2 are evenly spaced along the annulus of the upper base 101.

[0028] The upper base 101 has a pair of fixed frames 104 on its upper part according to the number of the two support arms. The upper base 101 has a corresponding snap ring interface 105 in the middle of the pair of fixed frames 104. The upper base 101 has an opening between the fixed frame 104 and the snap ring interface 105.

[0029] The upper end of the support arm 2 is provided with a bayonet, and the middle part of the bayonet is provided with an adjustable screw 201. The lower end of the support arm 2 is provided with a snap ring interface 202, and the inner side of the support arm 2 is provided with an arc-shaped support surface for supporting the outer wall of the flask.

[0030] The buckle assembly 3 includes a fixing pin 301 and a retaining spring 302. The two ends of the retaining spring 302 are connected to the retaining spring interface 105 and the retaining spring interface 202, respectively. The middle part of the retaining spring 302 is connected to the fixing pin 301. The bottom end of the support arm 2 is connected to the corresponding fixing frame 104 through the fixing pin 301.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.

[0032] In practical use, the automatic flask locking and placement rack according to this utility model includes a base 1, two symmetrically arranged support arms 2, and a buckle assembly 3.

[0033] The base 1 adopts a double-layer hollow design, which is convenient for placing the round bottom flask 4. The bottom layer is used to place it stably on the experimental table, and the upper base is designed with a fixing frame 104 and a snap ring interface 105. The upper and lower layers are connected by a metal fixing column 103.

[0034] The lower end of the support arm 2 is connected to the upper base 101 via a fixing pin 301, allowing it to move within a certain angle range.

The fixing pin 301 passes through the retaining spring 302 and connects the support arm 2 and the upper base.

[0036] When flask 4 is placed on support arm 2, the weight of flask 4 causes support arm 2 to rotate at a certain angle. Under the action of snap ring 302, the upper end of support arm 2 automatically engages with the neck of flask 4, achieving automatic locking. When flask 4 needs to be lifted, flask 4 is lifted upwards, and support arm 2 returns to its original position under the elastic action of snap ring 302. The movable buckle then rotates and releases, achieving automatic release.

[0041] Automated deployment: The design is simple and easy to grasp, which is conducive to the implementation of laboratory automation in conjunction with robotic arms;

[0042] Wide applicability: Suitable for flasks of different sizes, flexibly adapting to various experimental needs.

[0043] In summary, by utilizing the above-mentioned technical solution of this utility model, a movable support arm is set on the base through an elastic buckle assembly. The support arm rotates at a certain angle due to the gravity of the flask to achieve automatic locking of the flask. When the flask is lifted upward, the support arm resets through the elastic buckle assembly to actively unlock the flask. Moreover, the adjustable screw can also lock and reinforce the flask cake. This application is very convenient to operate, greatly improves safety, is suitable for flasks of different specifications, and flexibly adapts to various experimental needs.
