[0025] As Figure 1 Shown, in the embodiment provided by the utility model, top pressing assembly 20 includes top pressing plate 21, for driving top pressing plate 21 top pneumatic drive component 22 and for the transmission connection of top pressing plate 21 and top pneumatic drive component 22 top transmission column 23.User by pressing control component 11, top pneumatic drive component 22 drives top pressing plate 21 vertical downward movement and abuts with the top of net frame after this, top pneumatic drive component 22 continues to drive top pressing plate 21 vertical downward movement and installs the top of net frame on the top of box body, so as to realize the operation that the top of net frame is pressed and combined on the top of box body.

[0026] As Figure 1 And Figure 3As shown, the base 10 is further provided with a plurality of guide columns 12 for guiding the top compression plate 21. The base 10 is further provided with a mounting bracket 24 for mounting the top pneumatic driving component 22. In the embodiment provided by the utility model, the base 10 has four guide columns 12, and the top compression plate 21 is correspondingly provided with four guide holes. The guide columns 12 are inserted into the guide holes, and the top compression plate 21 is guided during the process of driving the top compression plate 21 to move vertically downward by the top pneumatic driving component 22 and assembling the top compression of the mesh frame on the top of the box. The displacement accuracy of the top compression plate 21 during the lifting process relative to the base 10 is effectively improved, thereby effectively ensuring the accuracy of the top compression assembly 20 for assembling the mesh frame on the top of the box. In addition, the top pneumatic driving component 22 is mounted on the base 10 through the mounting bracket 24, thereby effectively ensuring the stability of the top pneumatic driving component 22 mounted on the base 10, and effectively improving the stability of the top pneumatic driving component 22 for driving the top compression plate 21 to move vertically relative to the base 10.

[0027] As shown in Figure 1 and Figure 2 In the embodiment provided by the utility model, the side compression assembly 30 includes a side compression plate 31, a side pneumatic driving component 32 for driving the side compression plate 31, and a side transmission column 33 for drivingly connecting the side compression plate and the side pneumatic driving component 32. During the process of driving the top compression plate 21 to move vertically downward by the top pneumatic driving component 22 and assembling the top of the mesh frame on the top of the box, the pair of side pneumatic driving components 32 located on both sides of the box simultaneously drive the side compression plate 31 to move towards the side of the mesh frame and abut against the side of the mesh frame. Then, the side compression plate 31 continuously pushes the side of the mesh frame until the side of the mesh frame is assembled on the side of the box, thereby realizing the operation of simultaneously assembling the top and the side of the mesh frame on the top and the side of the box. In this way, the assembly efficiency of the sound box pressure maintaining device 100 for assembling the mesh frame on the box is effectively improved, the assembly process is simplified, the consistency of the frame assembled on the box is ensured, and the production cost is reduced.

The limiting block 34 can effectively limit the displacement of the side edge pneumatic driving component 32 when driving the side edge compression plate 31 to horizontally contract relative to the base 10, thereby effectively avoiding the horizontal contraction displacement of the side edge compression plate 31 being too large, causing the side edge compression plate 31 to collide with the side edge pneumatic driving component 32, and causing wear. In addition, the limiting portion on the base 10 is a plurality of limiting plates 13, and the plurality of limiting plates 13 enclose a limiting space for limiting the box. By placing the box in the limiting space for limiting the box enclosed by the plurality of limiting plates 13 on the base 10, the positioning accuracy of the box on the base 10 can be effectively ensured, thereby ensuring the accuracy of the top compression assembly 20 and the side edge compression assembly 30 in mounting the screen frame on the box.

[0029] In addition, as shown in Figure 1 and Figure 2 The bottom of the side edge compression plate 31 also has a limiting gap matched with the shape of the limiting plate 13. Through the limiting gap of the side edge compression plate 31, it can be effectively ensured that when the limiting plate 13 is embedded in the limiting gap of the side edge compression plate 31, the side edge pneumatic driving component 32 stops driving the side edge compression plate 31 to move relative to the base 10, thereby effectively avoiding the horizontal movement of the side edge compression plate 31 relative to the base 10 being too large, causing the components inside the box to be squeezed. The control component 11 is a control switch. By pressing the control switch, the user can control the top compression assembly 20 to compress the top of the screen frame to the top of the box, and a pair of side edge compression assemblies 30 to simultaneously compress the side edges of the screen frame to the side edges of the box, improving the convenience and control accuracy of the user during operation.

[0030] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the spirit and principles of the present application shall be included in the protection scope of the present application.
