[0039] Embodiment 2

[0040] Reference Figures 1-7 For the second embodiment of the utility model, the embodiment is based on the previous embodiment.

[0045] By setting the inclined shape, when the cover plate 102 is close to the shell 101, the locking block 201b will first contact the fixed block 201a, and will be pressed against the locking block 201b, so that the first spring 201c is compressed, and the locking block 201b moves to the first moving groove 102-1, which will not hinder the installation of the cover plate 102 and the shell 101. With the movement of the cover plate 102, when the locking block 201b moves to the coaxial position with the locking groove 201a-1, the two are clamped, and the right angle surface of the locking groove 201a-1 is fitted with the right angle surface of the locking block 201b, thereby preventing the locking block 201b from moving, and further locking the position of the cover plate 102, ensuring that the shell 101 and the cover plate 102 will not be separated.

[0046] Specifically, the upper and lower ends of the moving block 301b are inclined.

[0047] The upper inclined surface of the moving block 301b can be in contact with the inclined surface of the locking block 201b. In the initial state, the upper part of the moving block 301b is located in the locking groove 201a-1. During the clamping of the locking block 201b and the locking groove 201a-1, the inclined surface of the locking block 201b will press the upper inclined surface of the moving block 301b, so that the moving block 301b moves downward along the sliding groove 101-1.

[0049] The lower inclined surface of the moving block 301b can be clamped with the inner wall of the stress groove 301c-1. When the moving block 301b moves downward, the lower inclined surface of the moving block 301b will press the inner wall of the stress groove 301c-1, so that the moving plate 301c moves away from the sealing frame 301a along the through groove 101-2, thereby driving the pressing plate 301d to press the sealing frame 301a.

[0050] Specifically, the moving block 301b is fixed with a first supporting plate 301e on one side, and the shell 101 is provided with a second moving groove 101-3, and the first supporting plate 301e is slidably arranged in the second moving groove 101-3. The first supporting plate 301e is fixed with a third spring 301f on one side.

[0051] The first support plate 301e supports and positions the moving block 301b, the third spring 301f has the other end fixed to the inner wall of the second moving slot 101-3, the third spring 301f applies a continuous pushing force to the first support plate 301e, and ensures that the moving block 301b cannot move downward due to its own gravity in the absence of other external forces, and the third spring 301f is also used for resetting the moving block 301b.

[0052] Embodiment 3

[0053] With reference to Figures 1-7 As a third embodiment of the utility model, the embodiment is based on the previous two embodiments.

[0054] Specifically, the shell 101 is provided with a third moving slot 101-4, and the third moving slot 101-4 is provided with a second support block 301g.

[0055] The second support block 301g is fixed on one side of the moving plate 301c and positions the moving plate 301c, and the fourth spring 301h applies a pushing force to the second support block 301g and is used for resetting the moving plate 301c.

[0057] Through the cooperation of the guide column 301i and the guide slot 301g-1, the second support block 301g moves stably in the third moving slot 101-4, thereby ensuring the stability of the moving plate 301c, avoiding that the extrusion plate 301d cannot extrude the sealing frame 301a due to the deviation of the moving plate 301c, and further affecting the sealing effect.

[0058] Specifically, the number of locking blocks 201b is four, which are located on the four edges of the cover plate 102.

[0059] Specifically, the radio frequency amplifier 100 further comprises a connection port 103, and the connection port 103 is fixed on the shell 101.

[0061] In use, the groove on the cover plate 102 is aligned with the fixed block 201a, and then the cover plate 102 is pushed down, the locking block 201b will first contact the fixed block 201a and be pressed, so that the first spring 201c is compressed, the locking block 201b moves into the first moving groove 102-1 and does not hinder the installation of the cover plate 102 and the shell 101, and as the cover plate 102 moves, when the locking block 201b moves to the coaxial position with the locking groove 201a-1, the two are engaged, the locking groove 201a-1 straight face and the locking block 201b straight face are fitted, so as to hinder the movement of the locking block 201b, thereby locking the position of the cover plate 102, and ensuring that the shell 101 and the cover plate 102 cannot be separated.

[0062] In the process of locking block 201b and locking groove 201a-1 engagement, the locking block 201b slope will press the moving block 301b upper slope, so that the moving block 301b moves downward along the sliding groove 101-1, when the moving block 301b moves downward, the moving block 301b lower slope will press the inner wall of the stressed groove 301c-1, so that the moving plate 301c moves along the through groove 101-2 away from the sealing frame 301a, and drives the pressing plate 301d to approach the sealing frame 301a and press it, ensuring the sealing effect, so that dust and moisture cannot enter the shell 101 from the connection, providing a good protection environment for the internal precision electronic components, further improving the stability and reliability of the radio frequency amplifier 100.

[0063] When the cover plate 102 needs to be disassembled, adjust the pull ring 201g to the vertical state, at this time pull the pull ring 201g, drive the moving column 201d to move upward along the sliding groove 102-3, and make the second spring 201e compressed, the moving column 201d drives one end of the pull rope 201f to move, so that the pull rope 201f close to the locking block 201b moves synchronously, and then the locking block 201b moves away from the locking groove 201a-1, when the two are separated, the cover plate 102 can be separated from the shell 101 at this time, after separation, loosen the pull ring 201g, under the action of the second spring 201e, the moving column 201d will return to the initial position, the moving block 301b is no longer pressed by the locking block 201b, so that the moving block 301b and the moving plate 301c also return to the initial position, the pull rope 201f moves with the moving column 201d, under the action of the first spring 201c, the locking block 201b resets, and adjusts the pull ring 201g to the horizontal state.
