The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Fig. 1-2 are schematic diagrams of a radio frequency device according to an embodiment of the present invention, as shown in fig. 1-2, the radio frequency device includes a debugging rod a, a radio frequency device body B, a lock cylinder 2, and a spring 3. The radio frequency device body B is provided with an adjusting hole, and the debugging rod A is movably arranged in the adjusting hole. It should be noted that, the debugging rod a of this embodiment is set to be cylindrical, the adjusting hole is correspondingly set to be a circular hole matched with the debugging rod a, so that the debugging rod a can pass through the adjusting hole to reciprocate up and down. As an alternative embodiment, the adjustment rod a may also be a rod with a rectangular cross section, and the adjustment hole is correspondingly a rectangular hole.
Further, the key cylinder 2 of the present embodiment is disposed on the radio frequency device body B and is located on one side of the debugging rod a. The reed 3 includes a curved lock portion 31 that corrects the debugging rod a and a force receiving portion 32 that is connected to the key cylinder 2 and the curved lock portion 31, respectively. In the present embodiment, the force receiving portion 32 is urged by the key cylinder 2, so that the force receiving portion 32 drives the bent locking portion 31 to be bent and deformed, thereby locking the debugging rod a with pressure against the debugging rod a.
It should be understood that the interference between the curved locking portion 31 and the adjustment lever a in fig. 2 is to reflect the change of the state of the curved locking portion 31 after the force is applied to the key cylinder 2. In fact, the bent locking portion 31 is not ejected but elastically deformed and abuts against the debugging rod a by means of elastic force, so that the debugging rod a cannot move, thereby locking the debugging rod a.
Specifically, the force receiving portion 32 includes a first force receiving portion 321 extending from one end of the bent locking portion 31 and a second force receiving portion 322 extending from the other end of the bent locking portion 31, as shown in fig. 5. The first force-bearing portion 321 is connected to the rf device body B, and the second force-bearing portion 322 is connected to the lock cylinder 2. Therefore, the lock cylinder 2 can move relative to the radio frequency device body B to drive the second force-bearing part 322 to move relative to the first force-bearing part 321, so that the bent locking part 31 can be extruded to eject and abut against the debugging rod a, and the debugging rod a can be locked.
More specifically, in the present embodiment, the first force receiving portion 321 extends from the lower end of the bent lock portion 31, and the second force receiving portion 322 extends from the upper end of the bent lock portion 31. After the first force-bearing part 321 is fixed by the radio frequency device body B, the second force-bearing part 322 is pressed downwards by the lock cylinder 2, so that the bent locking part 31 is deformed and abuts against the debugging rod a to realize locking.
Further, as shown in fig. 3, a pressing portion 22 is fixed to the key cylinder 2, and the pressing portion 22 abuts against the second force receiving portion 322. The key cylinder 2 includes a lock cylinder 21, and the pressing portion 22 is provided in a plate-like structure and fixed to the lock cylinder 21. Thus, the pressing portion 22 is driven by the lock cylinder 21 moving downward to press the second force-receiving portion 322 downward, so that the curved locking portion 31 abuts against the debugging rod a to realize locking. Meanwhile, the pressing portion 22 of the plate-shaped structure can form a larger contact area with the second force-bearing portion 322, which is beneficial to improving the stability of the pressing process.
Further, in the present embodiment, the first force-receiving portion 321 and the second force-receiving portion 322 are provided with the through holes 33, and the shape, size and corresponding position of the through holes 33 are matched with those of the lock cylinder 21, as shown in fig. 5. That is, the lock cylinder 21 may pass through the second force receiving portion 322 and the first force receiving portion 321 in sequence from top to bottom through the through hole 33, as shown in fig. 3 to 4. Specifically, the lock cylinder 2 can perform a combined motion of rotation and vertical translation with respect to the second force receiving portion 322 and with respect to the first force receiving portion 321 through the through hole 33.
In this embodiment, the upper end of the lock cylinder 21 is further provided with a rotation portion 23, as shown in fig. 3. The rotation portion 23 of the present embodiment is provided as a rectangular groove extending downward from the upper surface of the lock cylinder 21, by which the lock cylinder 2 can be more conveniently rotated by the rotation portion 23. Alternatively, a lever fitted to the rotation portion 23 is embedded to form a labor saving lever for performing the rotation and pressing operations. It should be understood that, as an alternative embodiment, the rotation portion 23 may be provided as a structure protruding from the upper end of the lock cylinder 21 to both sides.
The radio frequency device of the embodiment further comprises a housing 1 fixed on the radio frequency device body B and accommodating the spring 3 and the pressing part 22, and the lock cylinder 2 penetrates through the inner and outer surfaces of the housing 1. Therefore, the pressing part 22 in the housing 1 can be matched with the housing 1 to clamp the pressing part 22 in the non-locking state and the locking state, that is, the position of the lock cylinder 2 in the non-locking state and the locking state is fixed, so that the bent locking part 31 is fixed in the two states, and the locking effect of the debugging rod a is ensured. Note that, the non-locked state is a state in which the reed 3 is not locked against the debugging rod a, and at this time, the lock cylinder 2 does not press the second force receiving portion 322 downward; the locked state is a state in which reed 3 is locked against debugging rod a, and at this time, lock cylinder 2 presses second force receiving portion 322 downward to eject curved locking portion 31.
Specifically, the top surface of the inner cavity of the housing 1 of the present embodiment is provided with a groove 12 which is recessed upward and opposite to the pressing portion 22, as shown in fig. 1. When the pressing portion 22 rotates to the unlocking position along with the lock cylinder 2, the pressing portion 22 is accommodated in the groove 12 and the curved locking portion 31 does not abut against the debugging rod a. Therefore, the distance difference between the groove 12 and the top surface of the inner cavity of the shell 1 in the vertical direction is formed, and the spring 3 with elasticity can be matched to realize the switching between the unlocking state and the locking state. The unlock position is a position where the pressing portion 22 is located in the unlock state.
Further, when the pressing portion 22 rotates to the locking position along with the key cylinder 2, the pressing portion 22 is separated from the groove 12 and abuts against the top surface of the inner cavity of the housing 1, and the curved locking portion 31 abuts against the debugging rod a. The lock position is a position where the pressing portion 22 is located in the locked state. That is, in the present embodiment, the pressing portion 22 in the non-locking position moves downward with the key cylinder 2 and rotates until abutting against the top surface of the inner cavity of the housing 1, and the position of the pressing portion 22 is the locking position.
As shown in fig. 6, the housing 1 is provided with a mounting hole 11 communicating with the recess 12, and the key cylinder 2 passes through the mounting hole 11. Specifically, the mounting hole 11 and the lock cylinder 21 are matched with each other, and the lock cylinder 2 passes through the mounting hole 11 from bottom to top so that the pressing portion 22 is located in the housing 1. It will be appreciated that the lock cylinder 21 can be rotated and reciprocated up and down through the mounting hole 11, so that control of whether the debugging rod a is locked or not can be achieved by moving the lock cylinder 2 to match the reed 3.
The housing 1 has an opening 10 communicating with the adjustment hole, and the curved locking portion 31 passes through the opening 10 when abutting on the adjustment lever a. That is, the opening 10 and the curved locking portion 31 are matched with each other so that the curved locking portion 31 can be ejected through the opening 10, achieving abutment against the debugging rod a.
It should be noted that, as shown in fig. 7-8, the end where the opening 10 is located is an arc-shaped end surface matched with the debugging rod a, so that the arc-shaped end surface can be attached to the debugging rod a. Thereby, the curved locking portion 31 is pushed out through the opening 10, and the pressure is applied to the debugging rod a to realize locking. It should be understood that the curved locking part 3 is ejected in fig. 8, and in practical cases, the curved locking part 3 is blocked by the debugging rod a and is elastically deformed, and the generated elastic force is converted into a pressure force for locking the debugging rod a.
In the radio frequency device of the embodiment, after the debugging rod a is inserted by an operator, the lock cylinder 2 is pressed down and rotated, so that the bent locking part 31 of the reed 3 is locked against the debugging rod a. And then, the lock cylinder 2 is rotated, so that the lock cylinder 2 is lifted to the initial position under the action of the elastic force of the reed 3, the bent locking part 31 is restored to the initial non-locking state and the locking of the debugging rod A is released, and an operator can take out or move the debugging rod A.
It should be understood that the radio frequency device of the present embodiment fixes the spring plate 3 in different states through the cooperation of the pressing portion 22 and the housing 1. As an alternative embodiment, other structures such as a snap structure or a self-locking structure may be used to fix the spring 3 in different states, for example, an automatic retractable locking mechanism may be formed by using a slope anti-self-locking principle in cooperation with the spring 3 having elasticity.
The embodiment of the invention provides a radio frequency device which comprises a radio frequency device body, a debugging rod, a lock cylinder and a reed. The debugging rod is arranged in an adjusting hole of the radio frequency device body, the lock cylinder is arranged on the radio frequency device body and is positioned on one side of the debugging rod, and the reed comprises a bent locking part right facing the debugging rod and a stressed part connected with the lock cylinder and the bent locking part. According to the radio frequency device provided by the embodiment of the invention, the force can be applied to the stressed part through the lock cylinder, so that the bent locking part is stressed to be bent and deformed and is abutted against the debugging rod, and the debugging rod is locked. Therefore, the problems of intermodulation and insertion loss of the radio frequency device can be improved, and the debugging efficiency is greatly improved.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
