A box cover is provided at the opening of the top wall of the audio - video transmission box, and a cooling device is provided at a position near the middle of the top wall of the box cover. The cooling device includes a fixing plate.

[0004] Although the above - mentioned patent document solves the problems of poor heat dissipation effect of the distributed audio - video transmission terminal and inability to effectively monitor the internal temperature, it still has the following disadvantages: The wire mesh is fixedly installed on the fixing plate, which is not convenient for quickly and thoroughly cleaning the impurities accumulated on the wire mesh. When the wire mesh is damaged due to long - term use, it cannot be quickly replaced, which is not conducive to the use of the distributed audio - video transmission terminal. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the following disadvantages in the prior art: The wire mesh is fixedly installed on the fixing plate, which is not convenient for quickly and thoroughly cleaning the impurities accumulated on the wire mesh. When the wire mesh is damaged due to long - term use, it cannot be quickly replaced, which is not conducive to the use of the distributed audio - video transmission terminal. Thus, a distributed audio - video transmission terminal is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A distributed audio - video transmission terminal includes an audio - video transmission box, a fixing plate, a cooling fan and a wire mesh. Two ear plates are fixedly installed on the fixing plate, and a fixing rod is fixedly connected between the two ear plates. The fixing rod is connected with a slider through a spring, and a cleaning component is arranged on the slider.

[0008] A slide bar with an L-shaped cross-section is slidably connected to the fixed plate. Two insertion rods are fixedly connected to one side of the slide bar. Two mounting blocks are fixedly connected to one side of the wire mesh. Through holes for connecting the insertion rods are formed in each mounting block. A rotating assembly is provided on one of the ear plates. The rotating assembly includes a rotating shaft rotatably connected to the ear plate. An extrusion piece is fixedly connected to the rotating shaft. The arc surface of the extrusion piece is in contact with the side surface of the slide bar.

[0009] Preferably, the cleaning assembly includes a scraping bar, and one end of the scraping bar is fixedly connected to the slider.

[0010] Preferably, a gravity block is fixedly connected to the rotating shaft, and the extrusion piece is inclined.

[0011] Preferably, a rubber block is fixedly connected to the upper surface of the slide bar, and the surface of the rubber block is fixedly connected to the lower surface of the slider.

[0012] Preferably, two positioning grooves are formed in the fixed plate, and each mounting block is clamped with the corresponding positioning groove.

[0013] Preferably, a sliding groove is formed in the fixed plate, and the slide bar is slidably connected to the sliding groove.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] During the process of the scraping bar moving to the right together with the slider, it will closely move along the upper surface of the wire mesh, thereby quickly scraping off the impurities accumulated on the surface of the wire mesh. When the slider moves to the left, it will move against the surface of the slide bar, and the side surface of the slide bar will move against the arc surface of the extrusion piece, causing the extrusion piece to rotate upward. After each L-shaped insertion rod moves with the slide bar, it will be separated from the mounting block, and then the wire mesh can be taken out for replacement or thorough cleaning, which is beneficial to the use of the distributed audio and video transmission terminal.

Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of clear narration, rather than to limit the scope of implementation of the present utility model. The change or adjustment of their relative relationship, without substantial change in the technical content, should also be regarded as the scope of implementation of the present utility model.

[0024] Referring to Figures 1 - 5 , a distributed audio - video transmission terminal, includes an audio - video transmission box 1, a fixed plate 2, a heat - dissipation fan and a wire mesh 5. Two ear plates 6 are fixedly installed on the fixed plate 2. A fixed rod 8 is fixedly connected between the two ear plates 6. The fixed rod 8 is connected to a slider 3 through a spring 7. A cleaning assembly is arranged on the slider 3. A sliding strip 9 with an L - shaped cross - section is slidably connected to the fixed plate 2. Two insertion rods 10 are fixedly connected to one side of the sliding strip 9. Two mounting blocks 11 are fixedly connected to one side of the wire mesh 5. Each mounting block 11 is provided with a through - hole for connecting the insertion rod 10. A rotating assembly is arranged on one of the ear plates 6. The rotating assembly includes a rotating shaft 12 rotatably connected to the ear plate 6. An extrusion piece 13 is fixedly connected to the rotating shaft 12. The arc surface of the extrusion piece 13 is in contact with the side surface of the sliding strip 9.

[0025] The cleaning component includes a scraping strip 4. One end of the scraping strip 4 is fixedly connected to the slider 3. When the scraping strip 4 moves along with the slider 3, it will move closely along the upper surface of the wire mesh 5, thereby quickly scraping off the impurities accumulated on the surface of the wire mesh 5. A gravity block 14 is fixedly connected to the rotating shaft 12. The pressing piece 13 is inclined. A chute is formed on the fixed plate 2, and the sliding strip 9 is slidably connected to the chute. The mass of the gravity block 14 is relatively large. Under the action of gravity, the gravity block 14 is vertically arranged. When the slider 3 moves against the sliding strip 9, the pressing piece 13 will rotate upward. After each L-shaped insertion rod 10 moves along with the sliding strip 9, it will disengage from the mounting block 11. At this time, the surface of the pressing piece 13 still fits against the side surface of the sliding strip 9, and both the pressing piece 13 and the gravity block 14 are inclined. When the slider 3 moves in the reverse direction and does not contact the sliding strip 9, the gravity block 14 will rotate in the reverse direction under the action of gravity. During the rotation of the pressing piece 13, it will push the relatively light sliding strip 9 to the initial position. At this time, the right end of the sliding strip 9 fits against the right inner wall of the chute (as shown in the appendix Figure 3 shown).

[0026] A rubber block 16 is fixedly connected to the upper surface of the sliding strip 9, and the surface of the rubber block 16 is fixedly connected to the lower surface of the slider 3. In the initial state, the upper surface of the rubber block 16 is in close contact with the lower surface of the slider 3. The friction between the slider 3 and the rubber block 16 is relatively large, which can effectively prevent the slider 3 from moving randomly. Two positioning grooves 15 are formed on the fixed plate 2, and each mounting block 11 is engaged with the corresponding positioning groove 15. The positioning groove 15 plays a role in positioning the installation of the mounting block 11. A rectangular rubber pad (not shown) is fixedly installed on the upper surface of the fixed plate 2, and the upper surface of the rubber pad fits against the lower surface of the wire mesh 5, which can effectively prevent impurities from directly passing through the gap.

[0027] In the present utility model, when the distributed audio-video transmission terminal is in use, manually move the slider 3 to the right (as shown in the appendix Figure 3 shown), the slider 3 will slide relative to the fixed rod 8. Since both ends of the spring 7 are fixedly connected to the slider 3 and the fixed rod 8 respectively, the spring 7 deforms simultaneously. When the scraping strip 4 moves along with the slider 3, it will move closely along the upper surface of the wire mesh 5, thereby quickly scraping off the impurities accumulated on the surface of the wire mesh 5. Remove the external force applied to the slider 3, and the slider 3 will move to the initial position under the elastic force of the spring 7. Manually move the slider 3 to the left (as shown in the appendix Figure 3As shown in the figure, during the movement of the slider 3, it will move against the surface of the slide bar 9, causing the slide bar 9 to slide in the chute. During the movement of the slide bar 9 towards the direction close to the rotating shaft 12, the side surface of the slide bar 9 will move against the arc surface of the pressing piece 13, causing the pressing piece 13 to rotate upwards. After the L-shaped inserting rods 10 move with the slide bar 9, they will be disengaged from the mounting block 11, and then the wire mesh 5 can be taken out for replacement or thorough cleaning, which is beneficial to the use of the distributed audio-video transmission terminal.

[0028] In the present invention, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation" and the like shall be understood in a broad sense.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
