[0023] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model will be further described in detail below by combining with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0024] In order to solve the technical problem that the base station filter is difficult to debug in the prior art, the utility model discloses a kind of debugging module, the debugging module is deformed by the deformation of the deformation area Debug filter, and by reducing the deformation variable of deformation area, the difficulty of filter debugging is reduced.

[0025] It needs to be explained that the debugging module is used for but not limited to base station filter etc., for the convenience of explanation, in the utility model, only with the debugging module being applied to base station filter as an example is described, and the principle of the debugging module being applied to other types of filters is substantially same with the principle of being applied to base station filter, and it is not described one by one here.

[0026] The debugging module provided in the utility model embodiment, as shown in Figures 1-2 It needs to be explained that the debugging module is used for but not limited to base station filter etc., for the convenience of explanation, in the utility model, only with the debugging module being applied to base station filter as an example is described, and the principle of the debugging module being applied to other types of filters is substantially same with the principle of being applied to base station filter, and it is not described one by one here.

[0027] Specifically, the debugging module is provided with cover plate 10, and cover plate 10 is sealed by being covered in filter cavity 40, cover plate 10 is provided with debugging area 11, and the thickness of debugging area 11 is less than the thickness of other regions of cover plate 10, so that debugging area 11 is easy to deform, and the filter can be debugged by controlling the deformation of debugging area 11. Since the debugging module is also provided with debugging rod 20, debugging rod 20 is connected to debugging area 11, and debugging rod 20 is inserted into cavity 40 when cover plate 10 is covered in filter cavity 40, debugging rod 20 can effectively reduce the debugging amount of the filter by being inserted into filter cavity 40, thereby reducing the deformation variable of debugging area 11 in the debugging process of the filter, facilitating the deformation control of debugging area 11, and reducing the difficulty of debugging the filter.

[0028] In one of the embodiments, as shown in Figures 1-2 The surface of cover plate 10 is provided with thinning groove 12, and debugging area 11 is formed on the bottom wall of thinning groove 12. Specifically, during the formation of debugging area 11, only thinning groove 12 needs to be milled on the surface of cover plate 10 after machining, which facilitates the processing and forming of debugging area 11.

[0029] In the embodiment, cover plate 10 is covered on cavity 40 through lower surface, and thinning groove 12 is provided on the upper surface of cover plate 10.

[0030] It can be understood that the debugging rod 20 can be fixedly connected to the debugging area 11 by integral molding, or connected to the debugging area 11 in any connection form such as sliding connection, as long as the lower end of the debugging rod 20 can extend into the cavity 40 when the cover plate 10 is covered on the cavity 40.

[0031] In one embodiment, the debugging rod 20 is threadedly connected with the debugging area 11. Specifically, by threadedly connecting the debugging rod 20 with the debugging area 11, the molding difficulty of the debugging rod 20 and the debugging area 11 can be reduced, and the insertion depth of the debugging rod 20 can be controlled according to the actual needs of the filter, so that the debugging module is suitable for base station filters of various models.

[0032] In this embodiment, before the cover plate 10 is covered on the cavity 40, the depth of the debugging rod 20 inserted into the cavity 40 is adjusted by rotating the debugging rod 20, and after the adjustment of the debugging rod 20 is completed, the cover plate 10 is covered on the cavity 40. After the cover plate 10 is covered on the cavity 40, the filter is only debugged by controlling the deformation of the debugging area 11, so as to avoid debris from entering the cavity 40.

[0033] In one embodiment, as shown in Figures 1-2 , the end of the debugging rod 20 is provided with a connecting hole 21 for a screwdriver. Specifically, when adjusting the debugging rod 20, the screwdriver is only needed to control the rotation of the debugging rod 20.

[0034] In one embodiment, as shown in Figures 1-2 , the debugging module further comprises a reinforcing table 111, the reinforcing table 111 is arranged on the debugging area 11, and the debugging rod 20 is threadedly connected with the reinforcing table 111 and the debugging area 11. Specifically, since the thickness of the debugging area 11 is relatively thin, the debugging area 11 is prone to deformation and damage. By arranging the reinforcing table 111, deformation and damage of the connecting part between the debugging area 11 and the debugging rod 20 during the operation of the debugging rod 20 can be avoided, so as to strengthen the protection of the debugging area 11.

[0035] In this embodiment, the reinforcing table 111 is integrally formed on the debugging area 11.

[0036] In one embodiment, as shown in Figures 1-2 , both ends of the debugging rod 20 extend out of the reinforcing table 111, and the lower end of the debugging rod 20 is used to extend into the filter cavity 40. Specifically, the lower end of the debugging rod 20 extends into the filter cavity 40, which can be used for filter debugging, and the upper end of the debugging rod 20 extends out of the reinforcing table 111, which can be gripped or grabbed by a control tool. During the deformation of the debugging area 11, the upper end of the debugging rod 20 only needs to be pulled or pressed, so as to facilitate the deformation operation of the debugging area 11.

[0037] In one embodiment, as shown in Figures 1-2 The debugging module further comprises a locking nut 30, which is threadedly connected to the upper end of the debugging rod 20 and used for locking the debugging rod 20.

[0038] In this embodiment, the debugging process is performed by pulling or pressing the screw rod and the locking nut, so as to increase or decrease the frequency of the filter.

[0039] It can be understood that the reinforcing table 111 can be in any shape, such as a square or a triangle, which can be penetrated by the debugging rod 20.

[0040] In one embodiment, as shown in Figures 1-2 The reinforcing table 111 is a circular boss. Specifically, by setting the reinforcing table 111 as a circular boss, the cylindrical structure of the debugging rod 20 can be matched, and the stress of each part of the debugging area 11 is more uniform, so that the deformation of each position of the debugging area 11 is consistent.

[0041] In one embodiment, as shown in Figures 1-2 The debugging area 11 is a circular area, and the reinforcing table 111 is arranged in the center of the debugging area 11. Specifically, by setting the debugging area 11 as a circular area, the stress of each position of the debugging area 11 can be balanced during the process of pulling or pressing the debugging rod 20, so that the deformation of the debugging area 11 is more coordinated.

[0042] In this embodiment, after the cover plate 10 is formed, only a circular groove is formed on the upper surface of the cover plate 10, so as to form the thinned debugging area 11 and the circular boss in the debugging area 11.

[0043] The utility model discloses an embodiment further provides a kind of base station filter, as shown in Figure 2 It comprises cavity 40 and debugging module, and debugging module is covered in cavity 40 by cover plate 10. Specifically, the base station filter is arranged by the debugging module, so that the debugging amount of the filter can be effectively reduced, and then the deformation amount of the debugging area 11 in the process of debugging the filter is reduced, the deformation of the debugging area 11 is facilitated, and the difficulty of debugging the filter is reduced.

[0044] In this embodiment, as shown in Figure 2 The inside of the cavity 40 is provided with a resonant rod 41, and the debugging area 11 is located on the upper side of the resonant rod 41.

[0045] In order to better understand the utility model, the following will be combined with Figures 1-2The utility model discloses a technical scheme is explained in detail: base station filter is in the debugging process, first through screwdriver rotation debugging pole 20, with the depth of adjusting debugging pole 20 to appropriate, then tighten locking nut 30, then again cover plate 10 is locked in cavity 40 through bolt, the cavity 40 is sealed, then through the upper end of pulling or pressing debugging pole 20, drive debugging area 11 deformation, can complete the debugging of filter, through the setting of the thinning of debugging pole 20 and debugging area 11, can effectively reduce the deformation of debugging area 11, reduce the difficulty of filter's debugging.
