[0017] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0018] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0019] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0020] In the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0021] In the present utility model, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0022] In the present utility model, if Figure 1-2 As shown, a vacuum glass vacuum needle is provided, comprising a rigid tube portion 1, a rubber tube portion 2 arranged at the upper end of the rigid tube portion 1, a support tube 3 is provided on the inner side of the rubber tube portion 2, the support tube 3 and the rigid tube portion are separate structures, and the upper end of the support tube 3 extends to the upper side of the rubber tube portion 2.

[0023] When the vacuum needle of the utility model is in use, the rigid tube portion can be inserted into the first sealant 4 and connected to the inner side of the vacuum glass, so that the rubber tube portion 2 leaks out of the first sealant 4. At this time, the external rigid vacuum tube can be inserted through the support tube 3 and negative pressure vacuuming can be started. After the vacuuming of the inner side of the glass is completed, the external rigid vacuum tube is lifted up, and the support tube 3 is pulled out together. During the process of pulling out the support tube 3, the rubber tube portion 2 is flattened by the negative pressure and automatically closed. After the support tube 3 is completely pulled out, the rubber tube portion 2 is flattened into a sheet, which is easier to automatically bend and adhere to the first sealant 4.

[0024] The utility model adopts the rubber tube part 2 to automatically seal, and the rubber tube part 2 has a stronger deformation ability, not only has a good sealing thoroughness, but also has a fast sealing response speed. It can also automatically bend after losing the support tube 3, simplifying the process of bending the vacuum needle before the second sealing operation.

[0025] In the illustrated embodiment, the lower end of the rubber tube 2 is sleeved on the outside of the rigid tube 1, and the lower end of the support tube 3 is in contact with the upper end of the rigid tube 1. As shown in the figure, the support tube can support the entire section of the rubber tube 2 to prevent the rubber tube 2 from being partially deformed when vacuuming.

[0026] In the illustrated embodiment, to be more specific, as shown in the figure, the rubber tube portion forms a connecting section 201 at the upper end of the rigid tube portion 1, the thickness of the rubber tube portion in the connecting section 201 is greater than the thickness in other areas, and the lower end of the support tube 3 and the upper end of the rigid tube portion 1 are respectively inserted in the connecting section 201 through interference. As shown in the figure, the connecting section 201 is fixed to the upper end of the rigid tube portion 1 and the support tube 3 at the same time, so that the rubber tube portion and the support tube 3 can be stably fixed. The thickness of the rubber tube portion 2 in other areas is thinned, which can increase the deformation capacity of the rubber tube portion 2 in other areas, so that it is easier to pull out the support tube 3, and it can also make the rubber tube portion 2 easier to deform.

[0027] In the illustrated embodiment, more specifically, as shown in the figure, the inner diameter of the rubber tube portion in the upper area of ​​the connecting section 201 is larger than the outer diameter of the support tube 3. As shown in the figure, by such an arrangement, the support tube 3 is more easily inserted into the rubber tube portion 2.

[0028] In order to more conveniently pull out the support tube 3, preferably, a lubricating oil layer is provided between the support tube 3 and the rubber tube portion 2. Thus, the lubricating oil layer can be applied to the outer side before the support tube 3 is inserted.

[0029] In order to facilitate the pulling out of the support tube 3, in the illustrated embodiment, a further optimized configuration is that a protruding operating portion 301 is provided on the top of the support tube 3. As shown in the figure, it is convenient for a person to grasp the operating portion 301 by hand or clamp it with a tool such as tweezers to facilitate pulling out the support tube 3.

[0030] In some embodiments, the external rigid exhaust pipe and the support pipe 3 may be tightly plugged together so that the support pipe 3 can be directly taken out when the external rigid exhaust pipe is lifted.

[0031] In the illustrated embodiment, more specifically, as shown in the figure, the upper end of the support tube 3 is expanded outward to form the operating portion 301. As shown in the figure, it is convenient to insert the external rigid exhaust pipe from the operating portion 301 into the inner side of the support tube 3.

[0032] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0033] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
