Description

Technical Field

[0001] This utility model relates to the field of vacuum tube connection technology, and more specifically, to a pressure-resistant vacuum tube clamp structure. Background Technology

[0002] A power distributor combines precise power measurement with Ethernet communication, providing users with a real-time monitoring mechanism for their devices and electricity. It also offers centralized monitoring software, allowing administrators to simultaneously monitor a large number of digital power strips. Furthermore, its electricity cost statistics function creates an energy-saving management mechanism to reduce electricity costs. Therefore, a digital power distributor is a power expansion product that combines safe management with energy conservation.

[0003] When using existing cabinet power distributors, the surface of the power distributor is usually provided with sockets to be used with plugs of other electrical appliances. However, after the plug is inserted into the socket, it is easy for the plug to accidentally fall off under a certain amount of pulling or rubbing force, which makes the fastening effect between the two not very good and affects the use.

[0004] To address the aforementioned issues, a pressure-resistant vacuum pipe clamp structure is urgently needed. Utility Model Content

[0005] The purpose of this invention is to provide a pressure-resistant vacuum pipe clamp structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, a pressure-resistant vacuum pipe clamp structure is provided, including an inner pipe and a locking structure. The two ends of the inner pipe are respectively inserted into two vacuum pipes to be connected, and an annular groove is provided on the surface of the middle part, with a support component installed inside.

[0007] The locking structure includes a pin, a first clamp, and a second clamp. Both the first clamp and the second clamp are rotatably mounted on the pin. There are at least two first clamps located at both ends of the inner tube. There are at least two second clamps located at the annular groove. The inner diameter of the first clamp is larger than the inner diameter of the second clamp.

[0008] Furthermore, the second clamp of the first clamp has the same structure, both consisting of two semi-circular clamps. The two semi-circular clamps are mounted on the pin through bushings, and the other sides of the two semi-circular clamps are fixed together by bolts.

[0009] Furthermore, the support includes a hollow tube, a connecting rod, and an inner top. The inner top is arranged in a ring around the hollow tube, and its top end is fixedly connected to the inner wall of the inner tube. The inner top is fixedly connected to the hollow tube through the connecting rod.

[0010] Furthermore, the inner walls of the first clamp and the second clamp are provided with mounting grooves, and an annular gasket is provided inside the mounting grooves.

[0011] Furthermore, the number of the support members is not less than four, and the installation positions of the support members correspond internally and externally to the installation positions of the first clamp and the second clamp.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] By setting a concave annular groove on the surface of the middle section of the inner tube, the vacuum tube is inserted from both ends of the inner tube and the end of the vacuum tube is placed in the annular groove. Then, the first clamp fixes the vacuum tube to the end of the inner tube, and the second clamp fixes the vacuum tube in the annular groove. The concave annular groove can prevent the vacuum tube from falling off, which significantly improves the locking ability of the device.

[0014] Support components are installed inside the inner pipe. In order to reduce the pressure on the inner pipe, the first and second clamps are installed on the outside of the support 3, that is, corresponding to each support component inside and out. In this way, the inner pipe is pressure-bearing inside through the support components, while the outside is locked and fixed by a locking structure. While achieving fixation, the pressure-bearing capacity of the vacuum pipeline and the inner pipe is also taken into account. Attached Figure Description

[0022] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Those skilled in the art will understand that, unless specifically stated otherwise, the singular forms “a,” “an,” and “described” used herein may also include the plural forms. It should be further understood that the word “comprising” as used in this specification means the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0024] Please see Figures 1-5 As shown, a pressure-resistant vacuum pipe clamp structure is provided, which is used to connect two vacuum pipes. Since it is a vacuum pipe, its outer wall must bear atmospheric pressure. With the addition of the external locking structure, the pressure borne by the vacuum pipe is further increased. In order to prevent the vacuum pipe from collapsing, this embodiment provides an inner pipe 1. The two ends of the inner pipe 1 are respectively inserted into the two vacuum pipes to be connected. The surface of the middle part is provided with an annular groove 2, and a support 3 is installed inside. The support 3 includes a hollow tube, a connecting rod and an inner top. The inner top is arranged in an annular shape with the hollow tube as the center. Its top end is fixedly connected to the inner wall of the inner pipe 1. The inner top is fixedly connected to the hollow tube through the connecting rod.

[0025] It is important to note that the two ends of the inner top are rounded. This is to prevent the inner pipe 1 from being broken by the sharp corners under pressure, and the rounded corner design can avoid this hidden danger.

[0026] The locking structure includes a pin 4, a first clamp 5, and a second clamp 6. The first clamp 5 and the second clamp 6 are rotatably mounted on the pin 4. There are at least two first clamps 5 located at both ends of the inner tube 1. There are at least two second clamps 6 located at the annular groove 2. The inner diameter of the first clamp 5 is larger than the inner diameter of the second clamp 6.

[0027] In this embodiment, the two ends of the inner tube 1 are respectively inserted into the two vacuum tubes and the ends of the vacuum tubes are positioned in the annular groove 2. The first clamp 5 clamps the vacuum tubes onto the outer surface of the inner tube 1, while the second clamp 6 clamps the vacuum tubes into the annular groove 2 to prevent the vacuum tubes from falling off the surface of the inner tube 1. The recessed annular groove 2 provides an obstacle when the vacuum tubes fall off, thus significantly enhancing the locking effect of the device.

[0028] Moreover, in this embodiment,

[0029] The first clamp 5 and the second clamp 6 have the same structure, both consisting of two semi-circular clamps. The two semi-circular clamps are mounted on the pin 4 via bushings 7, and the other side of the two semi-circular clamps are fixed together by bolts 8. The semi-circular structure design facilitates installation and disassembly. At the same time, in order to reduce the pressure on the inner pipe 1, the first clamp 5 and the second clamp 6 are installed on the periphery of the support member 3, that is, corresponding to each support member 3 internally and externally. In this way, the inside of the inner pipe 1 is pressure-bearing through the support member 3, while the outside is locked and fixed by a locking structure. While achieving fixation, the pressure-bearing capacity of the vacuum pipeline and the inner pipe 1 is also taken into account.

[0030] like Figure 5 As shown, an installation groove 9 is provided on the inner wall of the first clamp 5 and the second clamp 6. An annular gasket 10 is provided inside the installation groove 9. The annular gasket 10 can not only effectively increase the friction between the clamp and the vacuum pipe, but also improve the adaptability of the device. When facing vacuum pipes with different outer diameters, the fixing of vacuum pipes with different outer diameters can be achieved by replacing the annular gasket 10 with different inner diameters. Compared with the overall device, the annular gasket 10 has a simple structure and is easy to produce and install.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
