Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, and more particularly to a vacuum storage tank. Background Technology

[0002] Vacuum storage tanks are specially designed containers that require maintaining a vacuum state below atmospheric pressure to ensure the quality of stored substances. They are mainly used to store substances that are particularly sensitive to environmental conditions, such as volatile liquids, easily oxidized materials, or substances that need to be kept highly pure. These storage tanks have wide applications in many fields such as industry, agriculture, chemicals, petroleum, and food processing.

[0003] In practical use, when opening or closing vacuum storage tanks or adjusting their internal vacuum environment, operators often need to hold the tank before performing the operation. However, the amplitude of the operation causes the tank to move. This movement not only affects the stability of the tank but may also lead to changes in its placement, especially when frequent operations are required. Currently, the traditional solution is to press the tank firmly against a support surface to increase stability. However, this method requires the operator to continuously apply downward force to the tank, which not only increases the complexity and physical exertion of the operation but also makes it difficult to guarantee the stability of the tank when performing delicate operations such as rotation.

[0004] Therefore, in view of the above problems, there is an urgent need to propose a vacuum storage tank that can be positioned stably during operation, so as to effectively fix the position of the tank and reduce displacement caused by operation. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a vacuum storage tank that can be stably positioned during operation, thereby effectively fixing the position of the tank and reducing displacement caused by operation.

[0006] The technical solution of this utility model is as follows: A vacuum storage tank includes a storage tank, a gravity ball, a threaded neck, a tank lid, a suction pipe, a one-way exhaust pipe, a pressing assembly, a mounting ring, an elastic telescopic component, a rotating ring, a guide ring, and an arc-shaped suction cup. A threaded neck is provided at the top of the storage tank, and the tank lid is threaded onto the threaded neck. A suction pipe for air intake and suction operation, and a one-way exhaust pipe for air exhaust are connected to the tank lid. A pressing assembly that presses against the suction pipe is connected to the tank lid for vacuum suction. A mounting ring is provided at the bottom of the storage tank. Multiple elastic telescopic components are spaced apart circumferentially. A rotating ring is connected between the bottom ends of the elastic telescopic components. A guide ring is rotatably mounted on the rotating ring. Cavities are opened at both the upper and lower ends of the guide ring. The rotating ring is located in the upper cavity, while arc-shaped suction cups for adsorption and support are symmetrically arranged in the lower cavity. An annular groove is opened in the middle of the inner side of the guide ring, and a straight groove is symmetrically connected to the bottom of the annular groove. Gravity balls are also set on both sides of the lower part of the storage tank and placed in the two straight grooves respectively. The gravity balls can form a sliding fit with the straight grooves and the annular grooves, and the gravity balls abut against the guide ring.

[0007] As a preferred technical solution of this utility model, the pressing assembly includes a connecting cover, elastic elements and a piston rod. Multiple elastic elements are spaced apart on the top of the can cover, and a connecting cover is provided between the top ends of the elastic elements. A piston rod is provided at the bottom end of the connecting cover and placed inside the suction pipe. The piston rod slides in cooperation with the suction pipe.

[0008] As a preferred technical solution of this utility model, it also includes a protective sleeve, which is provided on the storage tank.

[0009] As a preferred embodiment of this utility model, the outer surface of the protective sleeve is provided with vertical stripes spaced apart.

[0010] As a preferred technical solution of this utility model, it also includes a pressing block, which is made of rubber material and is provided on the top of the connecting cover.

[0011] As a preferred technical solution of this utility model, it also includes a bottom pad, which is provided at the bottom of the storage tank.

[0012] This invention has the following advantages: It designs an innovative fixing mechanism that achieves stable placement of the storage tank through the cooperation between a gravity ball and a guide ring. During operation, the gravity ball moves along the straight groove under the action of the guide ring. Simultaneously, with the elastic support provided by the elastic telescopic component, the arc-shaped suction cup descends and contacts the supporting surface, forming an adsorption effect, thereby stabilizing the position of the storage tank. Subsequently, the gravity ball detaches from the straight groove, slides into the annular groove, and is fixed within the annular groove by rotation, thus blocking the guide ring and achieving effective support and fixation of the bottom of the storage tank. This process not only ensures the positional stability of the device during use and avoids unnecessary displacement, but also enhances the support strength of the entire structure, providing a solid guarantee for subsequent operations.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0021] Example: A vacuum storage tank, such as Figures 1-6As shown, the device includes a storage tank 1, a gravity ball 101, a threaded neck 2, a lid 3, a vacuum pipe 4, a one-way exhaust pipe 5, a pressing assembly, a mounting ring 8, an elastic telescopic component 9, a rotating ring 10, a guide ring 11, and an arc-shaped suction cup 12. A threaded neck 2 is provided at the top of the storage tank 1, and the lid 3 is threaded onto the threaded neck 2. The storage tank 1 is used to store items that require a vacuum state. The design of the threaded neck 2 allows the lid 3 to be tightly screwed onto the storage tank 1, ensuring a sealing effect. A vacuum pipe 4 for air intake and extraction, and a one-way exhaust pipe 5 for exhaust, are connected to the lid 3. The one-way exhaust pipe 5 ensures that outside air will not enter the tank and disrupt the vacuum state when there is no evacuation operation. A pressing component that works with the evacuation pipe 4 is connected to the tank lid 3 for vacuum evacuation. A mounting ring 8 is provided at the bottom of the storage tank 1. Elastic telescopic members 9 are spaced circumferentially at the bottom of the mounting ring 8. A rotating ring 10 is connected between the bottom ends of the elastic telescopic members 9. The elastic telescopic members 9 consist of a straight rod and a spring. The straight rod connects the mounting ring 8 and the rotating ring 10 and can form a sliding fit with the mounting ring 8. The spring then tightly holds the mounting ring 8 and the rotating ring 10 together. The connection allows the rotating ring 10 to be cushioned by the elasticity of the spring when it is pressed down, thus increasing the stability during operation. A guide ring 11 is rotatably mounted on the rotating ring 10. Both the upper and lower ends of the guide ring 11 have cavities 1101. The rotating ring 10 is located in the upper cavity 1101, while the lower cavity 1101 has symmetrically arranged arc-shaped suction cups 12 for adsorption support. The rotating ring 10 and the guide ring 11 together form an adjustable support structure, allowing the arc-shaped suction cups 12 on the guide ring 11 to adhere to a flat surface, increasing the stability of the storage tank 1 when placed. The side has an annular groove 1102 in the middle and a straight groove 1103 symmetrically connected to the bottom of the annular groove 1102. On the lower side of the storage tank 1, there are gravity balls 101 respectively placed in the two straight grooves 1103. The gravity balls 101 can form a sliding fit with the straight grooves 1103 and the annular groove 1102. The gravity balls 101 abut against the guide ring 11. The gravity balls 101 can roll in the straight grooves 1103 and the annular grooves 1102. When they stop in the annular groove 1102, they can abut against the two sides of the guide ring 11 by weight, thereby maintaining the stability and balance of the storage tank.

[0022] like Figures 1-3As shown, the pressing assembly includes a connecting cover 6, an elastic element 601, and a piston rod 701. The elastic elements 601 are spaced apart on the top of the can lid 3, and the connecting cover 6 is located between the top ends of the elastic elements 601. The piston rod 701 is located at the bottom end of the connecting cover 6. The piston rod 701 is tightly embedded inside the suction pipe 4, and the piston rod 701 slides in cooperation with the suction pipe 4. When the connecting cover 6 is pressed down by the pressing block 7, the piston rod 701 will move downward in the suction pipe 4, generating a suction effect. After being released, the restoring force of the elastic element 601 will cause the piston rod 701 to return to its original position, completing one suction cycle. By repeating this operation, a vacuum suction operation can be performed.

[0023] like Figure 1 and Figure 2 As shown, it also includes a protective sleeve 102. The protective sleeve 102 is provided on the storage tank 1, which can increase the aesthetics and have a non-slip effect. Vertical stripes are spaced apart on the outer surface of the protective sleeve 102, which can help improve the grip feel.

[0024] like Figure 1 and Figure 2 As shown, it also includes a pressing block 7, which is made of rubber and is provided on the top of the connecting cover 6 to improve the comfort of operation.

[0025] like Figure 6 As shown, it also includes a bottom pad 103. The bottom pad 103 is provided at the bottom of the storage tank 1 to protect it from scratches on the bottom of the tank by hard ground, and at the same time, it can work with the arc-shaped suction cup 12 to provide stable support for the storage tank 1.

[0026] During use, the storage tank 1 is first placed directly on a stable surface. The base pad 103 initially contacts the surface. Under the influence of gravity, the guide ring 11 moves downwards along the outer wall of the storage tank 1, causing the elastic telescopic component 9 to stretch. The gravity ball 101 follows the movement of the guide ring 11, sliding relative to the guide ring 11 along the inner wall of the straight groove 1103. After the gravity ball 101 leaves the straight groove 1103, it enters the annular groove 1102. The arc-shaped suction cup 12 then makes direct contact with the surface and adheres to it, working together with the base pad 103 to support the surface. The storage tank 1 is then rotated, causing the rotating ring 10 to rotate on the guide ring 11. Simultaneously, the gravity ball 101 enters the annular groove 1102 and rotates along it, eventually abutting against the groove. The guide ring 11 is positioned between two gravity balls 101, thus restricting its movement. It is then firmly attached to the table surface using an arc-shaped suction cup 12. The lid 3 can then be unscrewed to loosen the threads between it and the threaded neck 2 of the storage tank 1, allowing the lid 3 to be opened and the stored items placed inside the storage tank 1. The lid 3 is then closed and tightened. The pressing block 7 is then pressed down to connect the lid 6, causing the elastic element 601 to deform. The piston rod 701 also compresses the space inside the storage tank 1 under the downward pressure, forcing the air to be expelled from the one-way vent pipe 5. This process is repeated until the storage tank 1 reaches a vacuum state. Although there is some rotation during the operation, the guide ring 11 is not easily displaced due to the restriction of the gravity balls 101, thus stabilizing the position of the storage tank 1 during operation and coordinating the overall operation.

[0027] 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.
