DETAILED DESCRIPTION
[0024] The technical scheme in the utility model will be further described below in combination with the drawings and examples.
[0025] The utility model provides a kind of packing box pressing plate fixed support as shown in Figure 1 It includes:
[0026] Connecting shaft 1 is slidably connected with cylinder 11 sleeved thereon, and the bottom end of connecting shaft 1 is fixedly connected with disc 12.
[0027] Connecting blocks 2 are arranged around the connecting shaft 1 in a ring array, and two end faces of the connecting blocks 2 are respectively hinged with connecting rods 21, which are respectively hinged with the cylinder 11 and the disc 12, and the connecting blocks 2 are provided with connecting holes 22;
[0028] The pressing plate 3 is fixedly connected with a convex block 31 on the bottom surface for pressing the packaging box, and a connecting column 32 is fixedly connected with the connecting hole 22 on the top surface, and a fixing nut 33 is threadedly connected with the connecting column 32.
[0029] The adjusting block 4 is threadedly connected with the connecting shaft 1 for pressing the cylinder 11.
[0030] The working principle is that when the pressing plate 3 needs to be replaced, the fixing nut 33 is counterclockwise rotated to unlock the connecting column 32, and the connecting column 32 of the pressing plate 3 to be replaced is aligned with the corresponding size connecting hole 22. The cylinder 11 is moved along the connecting shaft 1 by sliding to drive the connecting rod 21 to link the connecting block 2 to adjust to the installation position of the pressing plate 3. At this time, the adjusting block 4 is clockwise rotated, and the axial force generated by the threaded transmission presses the cylinder 11 tightly on the connecting shaft 1, so that the connecting rod 21 and the connecting block 2 form a stable triangular support structure. Finally, the fixing nut 33 is tightened to eliminate the gap between the connecting column 32 and the connecting hole 22, and the rigid fixation of the pressing plate 3 is realized. The replacement process does not require any tools, and precise positioning is achieved through mechanical linkage, which ensures that the pressing plate 3 of different sizes can maintain a vertical pressing state with the packaging box. The locking force of the adjusting block 4 is maintained through the self-locking property of the threaded rod, preventing loosening during work.
[0031] In the embodiment, as shown in Figure 1 , Figure 2 , a plurality of grooves 13 in the axial direction are formed on the connecting shaft 1, and a convex rib matched with the grooves 13 is arranged on the cylinder 11 to limit the sliding of the cylinder 11 on the connecting shaft 1 in the axial direction. Through the cooperation of the convex rib and the groove 13, the cylinder 11 cannot move transversely on the connecting shaft 1, so that the moving direction of the connecting block 2 cannot deviate laterally, the cooperation between the connecting column 32 and the through hole of the connecting block 2 is more accurate, and the cooperation accuracy is improved, which is convenient for assembling and replacing the pressing plate 3.
[0032] In the embodiment, as shown in Figure 1 , a magnetic block 14 is fixedly connected to the bottom of the disc 12 for adsorbing the pressing plate 3. When the pressing plate 3 is replaced, the connecting column 32 of the pressing plate 3 is aligned and passes through the connecting hole 22 of the connecting block 2, and the magnetic block 14 adsorbs the pressing plate 3, and then the adjusting block 4 is rotated to fix the pressing plate 3, which is convenient for single-person operation and is used for auxiliary fixation of the pressing plate 3.
[0033] In this embodiment, as Figure 1 As shown, the top center of the pressure plate 3 has a recess 34 corresponding to the shape of the magnetic block 14, which is used to position the pressure block. Using the recess 34 to correspond to the magnetic block 14 facilitates the positioning of the pressure plate 3 and prevents the pressure plate 3 from moving laterally.
[0034] In this embodiment, as Figure 1 , Figure 2 As shown, the adjusting block 4 is configured as a regular hexagon. This allows the operator to rotate the adjusting block 4 to adjust the tension of the cylinder 11.
[0035] In this embodiment, as Figure 1 As shown, several adjusting rods 41 are fixedly connected to the adjusting block 4. This allows the operator to easily rotate the adjusting block 4 by hand, making it convenient to use.
[0036] In this embodiment, as Figure 2 As shown, four connecting blocks 2 are provided. Four connecting blocks 2 stabilize and fix the pressure plate 3 while reducing the number of adjusting and fixing threads. Of course, there can also be six connecting blocks 2.
[0037] In this embodiment, as Figure 1 , Figure 2 As shown, the top end of the connecting shaft 1 is provided with a threaded recess 15. This is used to connect the telescopic cylinder that drives the bracket to extend and retract, and it is easy to assemble and disassemble.
[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
