Specific embodiment
The invention is elaborated below in conjunction with specific embodiment.
As depicted in figs. 1 and 2, the wave filter of the present embodiment includes cell body 1, cover plate 2 and tuning plug 3, and cover plate 2 is covered on groove
At the opening of body 1, so as to form chamber 11, cover plate 2 offers installing hole 21, and tuning plug 3 is penetrated in installing hole 21 to be consolidated with cover plate 2
It is fixed, and chamber 11 is stretched into, tuning plug 3 is realized with the fixation of cover plate 2 by following structure：Cover plate 2 is provided with raised 23 Hes of fastening
Securing member 22, fastening projection 23 is outwardly, and herein, " interior ", " outward " are that for opposing chambers 11, tuning plug 3 penetrates peace
Dress hole 21 is simultaneously debugged after good position, assembles securing member 22, securing member 22 is locked with fastening raised 23, so that fastening is raised
23 clamp the tuning plug 3 for penetrating installing hole 21.Thus, tuning plug 3 is fixed with cover plate 2.Fastening raised 23 can be integrally formed at lid
Plate 2, also can be fixed on the plate body of cover plate 2 by way of riveting.Pressed from both sides by fastening raised 23 and the cooperation of securing member 22
Fasten tuning plug 3, instead of traditional fixed mode that is spirally connected, thus need not on the hole wall of installing hole 21 tapping,
Also metal fragment would not be produced to fall in chamber 11, so as to improve the performance of wave filter.
With reference to Fig. 2 and Fig. 5, fastening raised 23 stretches out what is formed by the hole wall of installing hole 21, so, fastening raised 23
It is one with the hole wall of installing hole 21, can more closely contacts with tuning plug 3, simple structure, installs firm.Fastening raised 23
Can be ring-type, as shown in Figure 2；Can also be multiple raised annular distributions, as shown in Figure 3.
As shown in figure 4, securing member 22 is provided with lock hole 221, and in the present embodiment, the two of the insertion securing member 22 of lock hole 221
End, in other embodiments, lock hole 221 can also be one end of blind hole, an insertion and firmware.Lock hole 221 is from its one end
It is tapered toward the other end, with reference to Fig. 5, when securing member 22 starts to be inserted in fastening raised 23 outside from the wider one end of its lock hole 221,
The lock hole 221 of securing member 22 fastens raised 23 due to the structure for gradually narrowing as securing member 22 is gradually in depth inserted in
Outside, the laterally compressing of the hole wall of the lock hole 221 of securing member 22 to fastening raised 23 is increasing so that fastening raised 23 is got over
More to clamp tuning plug 3.In addition, the structure that lock hole 221 is gradually narrowed, can also be such that tuning plug 3 moves from opposite direction, so as to
Ensure the accuracy of the position of tuning plug 3 and prevent tuning plug 3 from coming off (non-to fall in chamber 11).In the present embodiment, lock hole
221 hole wall is provided with screw thread (not shown), and the outside of fastening raised 23 can be threaded, it is also possible to be not provided with (fastening
Part 22 screw in during can make fastening projection 23 outside produce screw thread, similar to the process of external threading), securing member 22 with fastening
The locking by way of screw thread coordinates and is spirally connected of projection 23, so as to tuning plug 3 is fixed on cover plate 2.The screw thread knot of the present embodiment
Structure is optimal case, but is not limited to and this, and in other embodiments, securing member 22 can also be by other knots with fastening raised 23
Structure carrys out locking, for example, can be respectively provided with interface arrangment in fastening raised 23 and securing member 22, and both can be by way of clamping
Locking, the embodiment is compared to the helicitic texture for being originally embodiment, and flexibility ratio is worse.
As shown in Figure 2 and Figure 5, the outside of tuning plug 3 is provided with the projection 31 to side protrusion, and in the present embodiment, projection 31 is
Annular, projection 31 can block fastening raised 23 or the aperture outer of installing hole 21 (fastens the hole wall of raised 23 and installing hole 21
Non-integral situation), prevent tuning plug 3 from falling in chamber 11.The top of tuning plug 3 is provided with handle 32, convenient in assembly and adjustment
When grip tuning plug 3, after tuning plug 3 is fixed handle 32 cut off again.
Fig. 6 show the tuning plug 3 of another embodiment, and the tuning plug 3 of the embodiment is hollow structure, and its longitudinal section is in
" U " shape, the opening of tuning plug 3 stretches out to form projection 31 to side bending, to block the hole of fastening raised 23 or installing hole 21
Mouth outer (situations non-integral with the hole wall of installing hole 21 of fastening raised 23), prevents tuning plug 3 from falling in chamber 11.The enforcement
The structure of the tuning plug 3 of example can be manufactured with stamping forming technique, save manufacturing cost.
Above disclosed is only the preferred embodiment of the invention, can not limit wound of the present invention with this certainly
The interest field made, therefore the equivalent variations made according to the invention claim, still belong to the invention and are covered
Scope.
