Specifically, as Figure 5 、 8 、9 shown, first, the support cross - bar 613 on the extension frame structure can be telescopically moved inside the mounting rail 611, and then the distance between the two sets of chuck assemblies can be adjusted to meet strengthening structural members of different lengths.

[0058] The chuck assembly, as Figure 8 shown, is composed of a first mounting block 412 at the bottom of the vertical rod 411 and a fitting 413, and can be used to assemble strengthening structural members.

[0059] Embodiment 3

[0060] As other embodiments of the present invention, the strengthening structural member includes a reinforcing rib body 415, an end block 414, and a mounting groove 4151 opened at the end of the reinforcing rib body 415. The mounting groove 4151 is formed by connecting a second long groove and a first short groove. The end block 414 is an L-shaped structure composed of a long block and a short block. The end of the long block of the end block 414 is rotatably mounted at the end of the second long groove through a pin shaft, and a fourth threaded hole 4141 is opened on the short block of the end block 414. It further includes an assembly groove 4152 opened on the reinforcing rib body 415. A second threaded hole is opened in the middle of the assembly groove 4152. When the end block 414 deflects outwards and is horizontal, the fourth threaded hole 4141 is used to dock with the first threaded hole where the fitting 413 is located. When the end block 414 deflects inwards and is placed inside the mounting groove 4151, the fourth threaded hole 4141 is used to dock with the second threaded hole where the assembly groove 4152 is located.

[0061] According to the shaping and edge-finishing characteristics of the ventilation net body 111 and for matching with the chuck assembly, the strengthening structural member is improved as follows Figure 7 、 8 As shown in FIGS. 7 and 9, the strengthening structural member includes a reinforcing rib body 415. A mounting groove 4151 is opened at the end of the reinforcing rib body 415, and the end block 414 is rotatably mounted at the end of the mounting groove 4151. As Figure 8 shown in FIG. 9, when the end block 414 and the reinforcing rib body 415 are in a horizontal state, the front end of the end block 414 can act and be inserted into the fitting 413 on the first mounting block 412. At this time, the fourth threaded hole 4141 is used to dock with the first threaded hole where the fitting 413 is located. The assembly of the reinforcing rib body 415 and the fitting 413 can be completed through bolts, and then the assembly of the strengthening structural member and the chuck assembly can be completed, and then the pre-action of shaping and edge-finishing can be completed;

[0062] Furthermore, it further includes a pressing strip 8111 and a long-shaft bolt 8112. A third threaded hole is provided at the end of the long-shaft bolt 8112.

[0063] Since the end block 414 is an L-shaped structure composed of a long block and a short block, in cooperation with the opening shape of the mounting groove 4151 and the setting of the assembly groove 4152, after the two ends of the ventilation net body 111 are shaped and edge-finished, a ventilation net edge-finishing and shaping scheme with a frame-shaped structure can be extended;

[0064] Specifically, Figure 11, preferably, the width of the ventilation net body 111 is greater than the length of the reinforcing rib body 415 and is placed inside the short block of the end block 414. This is a schematic diagram of the state structure after shaping and trimming the two ends of the ventilation net body 111. At this time, manually flip the end block 414, that is, from Figures 12 to 13 , when the end block 414 deflects inward and is completely placed inside the installation groove 4151, at this time, the fourth threaded hole 4141 is used to dock with the second threaded hole where the assembly groove 4152 is located. By flipping the two end blocks 414, the edge parts on the front and back sides of the ventilation net body 111 are folded up and buckled at the end positions of the reinforcing rib body 415. At this time, as Figure 14 shown, the pressing strip 8111 is buckled on the edge parts on the front and back sides of the ventilation net body 111, and through the set long-axis bolt 8112, it is sequentially screwed into the second threaded hole opened in the middle of the assembly groove 4152, the fourth threaded hole 4141 at the end of the end block 414, and the third threaded hole at the end of the long-axis bolt 8112 to complete the locking of the connection. At this time, the two groups of pressing strips 8111 and the two groups of reinforcing rib bodies 415 form the frame structure of the ventilation net body 111.

[0065] Embodiment 4

[0066] As other embodiments of the present invention, each set of link transmission plate assemblies includes a first mounting member 314, a acting plate 313, and a second rod 318 and a first rod 317 connected between the acting plate 313 and the first mounting member 314. The second rod 318 is composed of a rod portion 3181 and a bent head portion 3182. The end where the rod portion 3181 is located is rotatably connected to the horizontal section of the first mounting member 314 through a pin shaft, and the end where the bent head portion 3182 is located is rotatably connected to the acting plate 313 through a pin shaft;

[0067] It further includes a first connecting member 315 and a second connecting member 319. The first connecting member 315 and the second connecting member 319 are respectively fixed on the first mounting member 314 and the acting plate 313, and a tension spring 316 is arranged between the first connecting member 315 and the second connecting member 319; and a motor 3122 fixed on the first mounting member 314. The output shaft of the motor 3122 penetrates through the through hole on the first mounting member 314 and acts on the pin shaft where the first rod 317 is located; an installation plate 320 arranged at the end of the acting plate 313, and a locking bolt 321 is arranged on the installation plate 320 for detachably installing the edge pressing head assembly.

[0068] In this embodiment, an implementation manner of the link transmission plate assembly is provided. As Figure 1 、 6 、7 and 8 shown, due to the structural setting of the second rod 3182 and in cooperation with the tension spring 316 connected between the first mounting member 314 and the acting plate 313, the first rod 317 is used as the driving rod. Specifically, in combination with Figures 7 to 10Process, when the first rod 317 is driven by the motor 3122 to deflect upward, under the action of the connection of the second rod 318 and the elastic force of the tension spring 316, it will force the action plate 313 to deflect with the second rod 3181 where the second rod 3182 is located as the fulcrum, so that when the front end of the action plate 313 is buckled downward, the rear end is lifted and moved forward. Under this action, the whole-edge pressing head assembly has a hook-shaped pulling action.

[0069] Furthermore, the whole-edge pressing head assembly includes a forming part 511, grooves 5117 opened on both sides of the forming part 511, and screw pressing block assemblies respectively installed on both sides of the forming part 511 for locking the second installation part 5111 and the end of the ventilation net body 111; each screw pressing block assembly includes a second installation part 5111 fixed on the forming part 511, a screw 5116 rotatably installed on the second installation part 5111, and a cross bar 5114 fixed at the end of the second installation part 5111. A sliding sleeve 5119 with limited sliding is arranged on the cross bar 5114. The sliding sleeve 5119 is threadedly connected with the screw 5116, and a pressing block 5113 fixed on the sliding sleeve 5119. When the pressing block 5113 presses the end of the ventilation net body 111, it can be completely placed inside the groove 5117;

[0070] And a handle 5112 installed on the second installation part 5111. The handle 5112 penetrates through the through hole on the second installation part 5111 and is connected with the screw 5116.

[0071] Through the provided whole-edge pressing head assembly, as Figure 7 、 8 and shown in 9, an installation method for connecting the to-be-shaped whole-edge end of the ventilation net body 111 is provided. When the ventilation net body 111 acts on the forming surface of the forming part 511, manually rotating the handle 5112 can drive the screw 5116 to rotate. Since the sliding sleeve 5119 is limited in sliding with the cross bar 5114, when the cross bar 5114 rotates, it can drive the sliding sleeve 5119 to reciprocate. When the sliding sleeve 5119 moves towards the direction close to the forming part 511, the two sides of the ventilation net body 111 can be pressed into the inside of the groove 5117 to achieve pressing and locking. Preferably, when the pressing block 5113 finishes pressing the ventilation net body 111, the upper surface of the pressing block 5113 is coplanar with the forming surface of the forming part 511 at this time.

[0072] Furthermore, the acting surface of the forming part 511 includes an arc part 5123 at the bottom and a forming plate 5125. The arc part 5123 is made of rubber material, and a hot pressing strip 5121 is arranged on the forming plate 5125 for hot pressing and forming of the ventilation net body 111.

[0073] As Figure 15As shown, through the structural setting of the forming part 511, under the design of the arc part 5123, its smooth arc surface is beneficial to the pulling and moving action of the whole-edge pressing head assembly on the ventilation net body 111. And when the forming part 511 is horizontally buckled on the upper surface of the ventilation net body 111, its arc part 5123 deforms and compacts itself on the front side of the reinforcing rib body 415. The forming plate 5125 is an existing mature technology, which is not the content of this application and will not be described in detail here. When the hot pressing strip 5121 works, it can perform hot melting forming on the acting position of the forming plate 5125 to realize the connection and stitching of the edge ends, such as Figure 11 , a hot melting forming belt in the shaded part is formed on the ventilation net body 111.

[0074] Furthermore, there is a connecting strip 5124 acting on the transition section between the hot pressing strip 5121 and the arc part 5123, and a number of uniformly distributed pressure sensors 5120 are arranged on the connecting strip 5124.

[0075] Such as Figure 15 , through a number of further arranged pressure sensors 5120, when the meshing transmission assembly drives the mounting frame to separate to both sides, and then the ventilation net body 111 is gradually flattened. When it is straightened, at this time, the pressure sensors 5120 are squeezed under the action of the straightened ventilation net body 111 and reach the set pressure value. When the pressure value of the pressure sensors 5120 is triggered, the single-chip microcomputer receives the signal and controls the operation of the motor 3122. In this control method, when the ventilation net body 111 is in a straightened state, the winding and whole-edge mechanism is further operated, and its hook-shaped pulling action further acts on the ventilation net body 111 to realize the winding and whole-edge forming action. In this process, when the ventilation net body 111 is in a frame structure, the tension of the ventilation net body 111 is improved.
