[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.

[0023] Reference Figures 1-3 An assembled cavity coupler includes an upper cavity 1, a lower cavity 2, and a locking ring 3 that cooperate with each other. A first protruding ring 4 extends outward from the bottom outer side of the upper cavity 1, and a second protruding ring 5 extends outward from the top outer side of the lower cavity 2. The outer side of the second protruding ring 5 and the inner side of the locking ring 3 are provided with mutually cooperating threads 6. A limiting ring 7 that cooperates with the first protruding ring 4 is fixedly connected to the top of the locking ring 3.

[0024] The top surface of the second convex ring 5 is fixedly connected to the positioning post 8, and the bottom surface of the first convex ring 4 is provided with a positioning hole 9 that matches the positioning post 8.

[0025] It should be noted that the assembled cavity coupler also includes a coupling circuit assembly fixedly installed in the lower cavity 2 and the upper cavity 1. Since the coupling circuit assembly is existing technology, it splits one signal into two unequal signals, which is common in the field of couplers, and will not be elaborated on further.

[0026] Reference Figures 1-3 When installing this assembled cavity coupler, the coupling circuit assembly is first fixedly installed in the lower cavity 2. After that, the upper cavity 1 is snapped onto the top of the lower cavity 2, the positioning post 8 is aligned and inserted into the positioning hole 9, and then the locking ring 3 is sleeved on the upper cavity 1. The locking ring 3 is pressed down and rotated until the limiting ring 7 is tightly attached to the first protruding ring 4. At this time, the upper cavity 1 and the lower cavity 2 are assembled.

[0027] Reference Figures 2-4 Foam 10 is provided between the first convex ring 4 and the limiting ring 7, and glue 11 is applied to both the top and bottom surfaces of the foam 10. The foam 10 and the glue 11 are used to bond the first convex ring 4 and the limiting ring 7, which prevents the locking ring 3 and the second convex ring 5 from rotating and loosening due to external interference in actual use, thus improving the installation stability.

[0028] When disassembling this assembled cavity coupler, simply drip adhesive remover into the gap between the limiting ring 7 and the outer wall of the upper cavity 1. After the adhesive remover dissolves the glue 11, the locking ring 3 can be rotated and disassembled. After maintenance, replace the foam 10 and glue 11.

[0029] Reference Figures 2-4 The top surface of the first convex ring 4 and the bottom surface of the limiting ring 7 are both provided with anti-slip textures 12. The anti-slip textures 12 increase the contact area between the glue 11 and the first convex ring 4 and the limiting ring 7, thereby further improving the installation stability.

[0030] A sealing ring 13 is provided between the first convex ring 4 and the second convex ring 5 to improve the waterproofness of the assembled cavity coupler, thereby improving its service life and stability.

[0031] Reference Figures 2-3 The positioning pin 8 and the positioning hole 9 are located inside the sealing ring 13, which avoids the problem of water entering the positioning hole 9 during normal use and making it difficult to clean, thus improving practicality.

[0032] There are two positioning posts 8 and two positioning holes 9. The two positioning posts 8 are symmetrically arranged on the top surface of the second convex ring 5. Too many positioning posts 8 will increase the cost. Two positioning posts 8 can position the upper cavity 1 and the lower cavity 2, thus reducing the construction cost.

[0033] Reference Figures 2-3 In actual use, when the upper cavity 1 and the lower cavity 2 are subjected to lateral opposing forces, the force acts directly on the positioning post 8, which can easily cause damage. In order to solve the above problem, an annular protective plate 14 extends upward from the inner side of the top of the lower cavity 2, and the outer side of the protective plate 14 is attached to the inner wall of the upper cavity 1. The protective plate 14 is used to limit the movement between the upper cavity 1 and the lower cavity 2, thereby protecting the positioning post 8 from damage.

[0034] 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.
