[0002] Connectors are components that provide connection and support during use, and are mainly used in fields such as machinery and aerospace.

[0003] Vacuum double-ended connectors provide strong support for the connecting components at both ends by evacuating the internal parts of the device. In contrast, traditional vacuum connectors have only one vacuum space inside. Although they can be adjusted to a certain extent, the limited space restricts the adjustment range, which limits the support specifications they can be used in and affects their applicability under different specifications.

[0004] Therefore, we provide a vacuum-type dual-head connector. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a vacuum double-head connector that achieves double-layer vacuum support and convenient gas supply.

[0006] In view of this, the present invention provides a vacuum double-ended connector, including a front connecting cylinder, a rear connecting cylinder, and a sealing post disposed between the front connecting cylinder and the rear connecting cylinder. The outer end of the front connecting cylinder is provided with a first connecting ring, and the outer end of the rear connecting cylinder is provided with a second connecting ring. The sealing post is installed on the inner end surface of the rear connecting cylinder, and a rear support chamber is formed inside the sealing post, extending into the interior of the rear connecting cylinder.

A front screw cylinder is formed in the rear half of the front connecting cylinder, and the front screw cylinder communicates with the outside through a first guide head.

[0007] Preferably, the outer side of the sealing column is provided with a threaded surface, which is threadedly connected to the inner wall of the front screw cylinder.

[0008] Preferably, a sealing gasket is installed on the inner surface of the front connecting cylinder, a sealing groove is formed on the inner surface of the rear connecting cylinder, the sealing post is located in the middle of the sealing groove, the sealing gasket is inserted into the sealing groove, and the diameter of the rear connecting cylinder is the same as that of the front connecting cylinder.

[0009] Preferably, the sealing column is threadedly connected to a reinforcing ring via the threaded surface. There are several reinforcing rings, and a reinforcing washer is provided on the surface of the reinforcing ring near the front connecting cylinder, and a reinforcing groove is installed on the surface of the reinforcing ring near the rear connecting cylinder.

[0010] Preferably, the reinforcing groove has the same specifications as the sealing gasket, the reinforcing groove has the same specifications as the sealing groove, the diameter of the reinforcing ring has the same specifications as the diameter of the rear connecting cylinder, and the reinforcing groove between two adjacent reinforcing rings is inserted into the reinforcing gasket.

[0011] Preferably, the second guide head is installed on the outside of the rear connecting cylinder and extends into the interior of the rear connecting cylinder. The second guide head communicates with the interior of the rear support chamber. A connecting bend is provided between the second guide head and the first guide head, and a vacuum head for vacuum connection is installed in the middle of the connecting bend.

[0012] Preferably, a placement tube is installed on the outer surface of the front connecting tube, and the placement tube is inserted into the air extraction head.

[0013] Compared with the prior art, this utility model provides a vacuum double-ended connector, which has the following advantages:

[0014] 1. This utility model, based on the sealed connection between the sealing column and the front screw cylinder, forms a first layer of connection space inside the front connecting cylinder, and based on the sealing of the rear connecting cylinder to the rear support chamber inside the rear, forms a second layer of connection space.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Example 1: A vacuum double-ended connector, such as Figures 1-4 As shown, it includes a front connecting cylinder 1, a rear connecting cylinder 2, and a sealing post 205 disposed between the front connecting cylinder 1 and the rear connecting cylinder 2. The outer end of the front connecting cylinder 1 is provided with a first connecting ring 104, and the outer end of the rear connecting cylinder 2 is provided with a second connecting ring 206. The sealing post 205 is installed on the inner end surface of the rear connecting cylinder 2, and a rear support chamber 201 is opened inside the sealing post 205, and the rear support chamber 201 extends into the interior of the rear connecting cylinder 2. The sealing post 205 is connected to the outside through a second guide head 202. The rear half of the front connecting cylinder 1 is provided with a front screw cylinder 101, and the front screw cylinder 101 is connected to the outside through the first guide head 102.

[0026] First, based on the sealed connection between the sealing column 205 and the front screw cylinder 101, a first layer of connection space is formed inside the front connecting cylinder 1. Then, based on the sealing of the rear connecting cylinder 205 and its internal rear support chamber 201, a second layer of connection space is formed. Through the connection of the first guide head 102 and the second guide head 202 with the external vacuum device, a vacuum is formed inside the front screw cylinder 101 and the rear support chamber 201. Guided by the connection of the first connecting ring 104 and the second connecting ring 206 on both sides, the device achieves a double-layer vacuum double-head connection effect. This further enhances the connection strength of the device under double vacuum connection. Furthermore, by selectively using the front screw cylinder 101 and the rear support chamber 201, the device can be used in one or two vacuum states, enabling more accurate and efficient use. Adjusting the distance between the front connecting cylinder 1 and the rear connecting cylinder 2 adjusts the sealing space inside the front screw cylinder 101. Thus, through structural adjustments, the vacuum specifications within the device are adjusted, thereby increasing the overall connection strength of the device.

[0027] like Figures 1-4 As shown, a threaded surface 203 is installed on the outer side of the sealing column 205, and the threaded surface 203 is threadedly connected to the inner wall of the front screw cylinder 101.

[0028] A sealing gasket 103 is installed on the inner end surface of the front connecting cylinder 1, and a sealing groove 204 is opened on the inner end surface of the rear connecting cylinder 2. The sealing post 205 is located in the middle of the sealing groove 204, and the sealing gasket 103 is inserted into the sealing groove 204. The diameter of the rear connecting cylinder 2 is the same as that of the front connecting cylinder 1.

[0029] Based on the threaded connection between the front screw cylinder 101 and the threaded surface 203, the front connecting cylinder 1 and the rear connecting cylinder 2 can be fixed. Under the positioning guidance of the sealing groove 204 and the sealing washer 103, as the front connecting cylinder 1 and the rear connecting cylinder 2 gradually move relative to each other, the sealing groove 204 gradually squeezes and positions the sealing washer 103. Thus, through the deformation of the sealing washer 103, the connection between the front connecting cylinder 1 and the rear connecting cylinder 2 is further sealed, ensuring the sealing stability of the vacuum inside the front screw cylinder 101 and improving its reliability during connection and use.

[0030] Example 2: A vacuum double-ended connector, such as Figures 1-4 As shown, the sealing column 205 is threadedly connected to a reinforcing ring 6 via a threaded surface 203. There are several reinforcing rings 6, and a reinforcing washer 602 is provided on the surface of the reinforcing ring 6 near the front connecting cylinder 1. A reinforcing groove 601 is installed on the surface of the reinforcing ring 6 near the rear connecting cylinder 2.

[0031] The reinforcing groove 601 has the same specifications as the sealing gasket 103, the reinforcing groove 601 has the same specifications as the sealing groove 204, the diameter of the reinforcing ring 6 has the same specifications as the diameter of the rear connecting cylinder 2, and the reinforcing groove 601 between two adjacent reinforcing rings 6 is inserted into the reinforcing gasket 602.

[0032] Firstly, based on the threaded connection between the reinforcing ring 6 and the threaded surface 203, and based on the positioning and pressing of the sealing gasket 103 by the reinforcing washer 602, the positioning and pressing of the sealing groove 204 by the reinforcing groove 601, and the mutual insertion of the reinforcing groove 601 and the reinforcing washer 602, when the reinforcing ring 6 is used, the reinforcing ring 6, the front connecting cylinder 1, and the rear connecting cylinder 2 are mutually tightened. Thus, when adjusting the distance between the front connecting cylinder 1 and the rear connecting cylinder 2, a corresponding number of reinforcing rings 6 are added to ensure their tight connection and sealing effect. Furthermore, the insertion of the reinforcing groove 601 and the reinforcing washer 602 ensures the stability of the seal between two adjacent reinforcing rings 6, while also achieving the effect of tightening the connection of adjacent components, thereby improving the overall tightness when the connection is used after adjustment.

[0033] like Figures 1-4 As shown, the second guide head 202 is installed on the outside of the rear connecting cylinder 2 and extends into the interior of the rear connecting cylinder 2. The second guide head 202 is connected to the interior of the rear support chamber 201. A connecting bend 3 is provided between the second guide head 202 and the first guide head 102. A vacuum head 4 for vacuum connection is installed in the middle of the connecting bend 3.

[0034] A placement tube 5 is installed on the outer surface of the front connecting tube 1, and the placement tube 5 is inserted into the air extraction head 4.

[0035] By simultaneously pumping air into the front screw cylinder 101 and the rear support chamber 201 under the support of the connecting bend 3 and the connection of the suction head 4, and under the guidance of the first guide head 102 and the second guide head 202, the device can be simultaneously pumped out into a double vacuum, which improves the efficiency and convenience of the device. Under the elastic tension of the connecting bend 3 itself, it can meet the connection requirements of the device under different specifications, ensuring that the connection is stable and reliable.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
