Description

Technical Field

[0001] The present invention relates to the technical field of chemical instrument equipment, and more specifically, to an automatic locking flask placement rack. Background Art

[0002] Most of the currently widely used flask placement racks in laboratories adopt a simple mechanical structure and require manual repeated operations for fixing and loosening steps. This method has two major drawbacks: First, laboratory personnel need to frequently adjust the position of the fixture, especially when processing multiple flasks in batches, the efficiency is low; Second, it is difficult to standardize the manual force application, and it is easy to cause the flask to tip over due to improper fixing of the flask, both of which may lead to liquid leakage and even experimental accidents. In addition, although the existing electric fixing devices on the market can achieve automatic locking, they have significant limitations: relying on motors, gear sets and screw drive systems, resulting in a large volume and high cost, and most of them have a fixed stroke and are difficult to be compatible with flasks of different specifications, and the maintenance is inconvenient.

[0003] In summary, there is an urgent need to develop a flask fixing solution that combines operational convenience, stability and low maintenance cost. Summary of the Invention

[0015] As Figure 1-9 shown, an automatic locking placement rack for flasks according to an embodiment of the present invention includes a base 1, and at least two support arms 2 are provided at the upper end of the base 1. Each support arm 2 is movably connected to the base 1 through a corresponding elastic buckle assembly 3.

[0016] The base 1 includes an upper base 101 and a lower base 102 that are correspondingly arranged up and down, and the upper base 101 and the lower base 102 are connected by a metal fixing column 103.

[0017] Both the upper base 101 and the lower base 102 are circular rings, and the support arms 2 are evenly spaced along the circular ring of the upper base 101.

[0018] Corresponding pairs of fixing frames 104 are provided on the upper part of the upper base 101 according to the number of the support arms 2. A corresponding first snap ring interface 105 is provided in the middle of the paired fixing frames 104 on the upper base 101, and an opening is provided between the fixing frame 104 and the first snap ring interface 105 on the upper base 101.

[0019] The upper end of the support arm 2 is provided with a bayonet, an adjustable screw 201 is provided in the middle of the bayonet of the support arm 2, a second snap ring interface 202 is provided at the lower end of the support arm 2, and an arc-shaped support surface for supporting the outer wall of the flask is provided on the inner side of the support arm 2.

[0020] The buckle assembly 3 includes a fixing pin 301 and a snap ring 302.

The middle of the snap ring 302 is connected to the fixing pin 301, and the bottom end of the support arm 2 is connected to the corresponding fixing frame 104 through the fixing pin 301.

[0021] To facilitate the understanding of the above technical solution of the present invention, the above technical solution of the present invention will be described in detail below in terms of specific usage methods.

[0022] In specific use, an automatic locking placement rack for a flask according to the present invention includes a base 1, two symmetrically arranged support arms 2, and a buckle assembly 3.

[0023] The base 1 adopts a double-layer hollow design, which is convenient for placing a round-bottom flask 4. The bottom layer is used for stably placing on the experimental bench. The upper-layer base is designed with a fixing frame 104 and a first snap ring interface 105, and the upper and lower layers are connected by a metal fixing column 103.

[0024] The lower end of the support arm 2 is connected to the upper-layer base 101 through a fixing pin 301 and can move within a certain angle range. An arc-shaped support surface adapted to the outer wall of the flask 4 is provided inside the support arm 2 for supporting the flask 4. In addition, a second snap ring interface 202 is provided at the lower end of the support arm 2, and a manually adjustable screw 201 is provided at the upper end of the support arm 2 for adjusting the placement of flasks of different caliber specifications.

[0025] The buckle assembly 3 is composed of a fixing pin 301 and a snap ring 302.

The fixing pin 301 passes through the snap ring 302 and connects the support arm 2 and the upper layer of the fixed base.

[0026] When the flask 4 is placed on the support arm 2, the gravity of the flask 4 causes the support arm 2 to rotate by a certain angle. Under the action of the snap ring 302, the upper end of the support arm 2 automatically buckles on the neck of the flask 4 to achieve automatic locking; when the flask 4 needs to be picked up, the flask 4 is lifted upward, and the support arm 2 resets under the elastic action of the snap ring 302, and the movable buckle rotates and loosens accordingly, achieving automatic release.

[0027] The effects of the present invention: Operational convenience: The automatic locking and releasing functions simplify the operation process of placing and taking flasks by experimental personnel, saving time and energy; Improved safety: The reliable automatic locking mechanism effectively prevents the flask from accidentally tipping over during the experiment, reducing the risk of liquid leakage and safety accidents; Structural advantages: The overall structure is reasonably designed, easy to manufacture and maintain, and has a low cost; Automated deployment: The design is simple and easy to grasp, which is conducive to the implementation of laboratory automation in cooperation with robotic arms; Wide applicability: It is applicable to flasks of different specifications and can flexibly meet various experimental needs.

[0028] In summary, by means of the above technical solution of the present invention, a support arm with a movable connection is arranged on the base through an elastic buckle assembly. The support arm rotates by a certain angle under the action of the gravity of the flask to achieve automatic locking of the flask. When the flask is lifted upward, the support arm is reset through the elastic buckle assembly to achieve automatic unlocking of the flask. Moreover, the adjustable screw can also lock and reinforce the flask. The operation of this application is very convenient, and the safety is greatly improved. It is applicable to flasks of different specifications and can flexibly meet various experimental requirements.
