Description

Technical Field

[0001] The utility model relates to the technical field of electromagnetic wave conduction, in particular to a waveguide flange quick connection device. Background Art

[0002] A waveguide is a component used to transmit high-frequency electromagnetic waves. Typically made of metal, it offers excellent electrical and thermal conductivity. Waveguides are typically tubular with flanges at both ends for connection. Microwave and radio frequency systems require waveguide flange connectors to connect different waveguides, forming a complete transmission path for signal transmission and control.

[0003] Chinese utility model patent application number 201721864401.7 (authorization publication number CN 207868367 U) discloses a waveguide component connector device, which has a large-sized stud and locking nut respectively mounted on the waveguide components. When interconnecting, the locking nut is rotated clockwise or counterclockwise so that the internal thread on the locking nut matches the external thread on the stud, thereby driving the flange surface of the waveguide components to be interconnected to move axially, thereby achieving the purpose of interconnecting the waveguide components.

[0004] However, since both ends of the waveguide have flanges with large outer diameters, the studs and locknuts cannot be directly inserted into the waveguide. This requires splitting the studs and locknuts in the middle (i.e., splitting them equally up and down), snapping them onto the rear of the flanges of the two waveguide components to be connected, and then using screws to assemble the studs and locknuts into a complete stud and locknut. This process is relatively cumbersome and complex. Therefore, further improvements are needed to the existing waveguide flange quick connection device. Utility Model Content

[0005] The technical problem to be solved by the utility model is to propose a waveguide flange quick connection device with simpler structure and use in response to the above technical status quo.

[0006] The technical solution adopted by the present invention to solve the above technical problems is: a waveguide flange quick connection device, including a hollow first connecting piece for the waveguide flange to pass axially and a second connecting piece threadedly connected to the first connecting piece, characterized in that: there are two second connecting pieces, which can be threadedly connected to the two ends of the first connecting piece respectively, and an axially extending through hole is opened in the middle of each second connecting piece, the inner diameter of the through hole is smaller than the outer diameter of the waveguide flange, and at the same time, a radial channel is further opened on the peripheral wall of each second connecting piece, which passes through the two end surfaces of the second connecting piece and the through hole, and the radial channel can allow the waveguide tube of the waveguide to radially enter the through hole.

[0007] Preferably, the two second connecting members each have an axially recessed groove on the opposite end surfaces thereof and connected to the through hole, the groove being used to accommodate a waveguide flange. The waveguide flange is embedded in the second connecting member, thereby reducing the volume of the connecting portion.

[0008] Specifically, the first connecting member has an external thread to form a hollow stud, and the second connecting member has an internal thread matched with the first connecting member to form a hollow threaded sleeve.

[0009] Preferably, the internal thread of the second connecting member is provided on the inner side wall of the groove.

[0010] Preferably, the groove depth of the second connecting member is not greater than the circumferential thickness of the connected waveguide flange, so that the second connecting member and the first connecting member can continue to maintain a close fit between the two waveguide flanges after being tightened.

[0011] In order to prevent the second connecting member from slipping when the user applies force to tighten it, preferably, the outer side wall of the second connecting member has anti-slip grooves.

[0012] Preferably, at least one pair of planes for clamping by the clamping member is further provided on the peripheral wall of each second connecting member, and the two planes in each pair of planes are respectively located on both sides of the radial channel to facilitate tool clamping and force application.

[0013] Preferably, the width of the radial channel is the same as the inner diameter of the through hole to facilitate processing.

[0014] Compared to the prior art, the present invention incorporates a radial channel in the second connector, allowing the waveguide to enter radially directly from the radial channel into the through-hole. Therefore, during assembly, there is no need to first separate the stud and locknut, attach them to the waveguide, and then screw them back together, as is required in the prior art. This complex process can be eliminated, allowing the second connector to be quickly connected to the waveguide flange directly through the radial channel. Furthermore, the presence of the radial channel allows the second connector to elastically deform when tightened, thereby increasing friction between the threads of the first connector and the second connector. This elastic deformation of the internal structure resists loosening caused by vibration and external forces, achieving a preventive effect and maintaining a tight fit between the two interconnected waveguide flanges.

[0020] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 5 The figure shows a preferred embodiment of the waveguide flange quick connection device of the present invention.

[0022] This embodiment includes a first connecting member 1 and two second connecting members 2. Figure 2 The first connecting member 1 is hollow and can allow the waveguide flange 31 to axially pass through it, and the two second connecting members 2 can be respectively threadedly connected to the two ends of the first connecting member 1.

[0023] Specifically, as a preferred embodiment, the first connecting member 1 has an external thread and becomes a hollow stud, and the two second connecting members 2 have internal threads that match the first connecting member 1 and become hollow screw sleeves, such as Figure 1 In addition to the solution of the second connecting member 2 being sheathed outside the first connecting member 1 shown in this embodiment, in production, external threads can be provided on the second connecting member 2 to form a hollow stud, and internal threads can be provided on the first connecting member 1 to form a hollow screw sleeve, so that the first connecting member 1 is sheathed outside the second connecting member 2. The technical effect that can be achieved is similar to that of this embodiment.

[0024] Please continue to see Figure 2 , an axially extending through hole 22 is opened in the middle of each second connecting member 2, and a radial channel 21 is also opened on the peripheral wall of each second connecting member 22, which passes through the two end surfaces of the second connecting member 2 and the through hole 22. The radial channel 21 can allow the waveguide tube 32 of the waveguide 3 to radially enter the through hole 22, as shown in FIG. Figure 3 As shown, the width of the radial channel 21 is the same as the inner diameter of the through hole 22 to facilitate processing. In addition, the inner diameter of the through hole 22 is set to be smaller than the outer diameter of the waveguide flange 31, which ensures that the waveguide 3 cannot axially separate from the second connector 2.

[0025] like Figure 4 As shown, the opposing surfaces of the two second connectors 2 each have an axially recessed groove 23 intersecting the through hole 22. The groove 23 is used to accommodate the waveguide flange 31. The internal threads are located on the inner sidewalls of the grooves 23. When tightened, the externally threaded first connector 1 is located in the gap between the waveguide flange 31 and the grooves 23. This makes the overall assembly more compact.

[0026] refer to Figure 5 When the above-mentioned groove 23 is designed, the depth of the groove 23 is not greater than the axial thickness of the waveguide flange 31. When the second connecting member 2 is tightened to the first connecting member 1, the bottom surface of the groove 23 will continuously push the waveguide flange 31 accommodated in the groove 23 to fit tightly against the other waveguide flange 31 to be interconnected, and continue to limit the separation of the two waveguide flanges 31 after the interconnection is completed.

[0027] In order to prevent the user from slipping when tightening the second connecting member 2 , anti-slip grooves 24 are further provided on the outside of the second connecting member 2 in this embodiment.

[0028] At the same time, taking into account the force applied by tools such as wrenches, each second connecting member 2 is further provided with at least one pair of flat surfaces 25 for clamping by a clamping member (such as a wrench) on its peripheral wall. The two flat surfaces 25 in each pair of flat surfaces 25 are respectively located on both sides of the radial channel 21, so that the periphery of the second connecting member is subjected to uniform force, making it easy to rotate the second connecting member.

[0029] The working principle of this embodiment is as follows:

[0030] During the connection and assembly process, the user inserts the waveguide tube 32 portion of the first waveguide 3 to be connected radially into the through hole 22 of one of the second connectors 2 through the radial channel 21, and the waveguide flange 31 is accommodated in the groove 23 of the second connector 2. Subsequently, the first connector 1 is rotated clockwise or counterclockwise until it is fully tightened, completing the connection between the first end of the first connector 1 and the second connector. Next, the user uses a marker or a positioning pin to align the waveguide flange 31 of the second waveguide 3, completing the precise docking of the second waveguide flange 31 with the first waveguide flange 31. Afterwards, another second connector 2 is inserted into the outside of the waveguide tube 32 of the second waveguide 3 through the radial channel 21, and the second second connector 2 is rotated in the same manner and fixed to the other end of the first connector 1, thus completing the quick connection of the two waveguide flanges 31. When the interconnection needs to be disconnected, it can be quickly achieved by simply reversing the operation.
