Description

Technical Field

[0001] This utility model relates to the technical field of printing press wall panel beams, specifically a detachable printing press wall panel beam. Background Technology

[0002] The overall structure of the printing press is based on two wall panels as supporting components. A large number of shaft and roller parts are installed between the two wall panels, allowing the continuous printing materials to pass through the orderly arranged shafts, rollers and cylinders. The wall panels are connected by crossbeams to achieve assembly and support between the wall panels.

[0003] The wall panels and beams are usually fixed by integrated welding, which makes them impossible to disassemble and replace, leading to difficulties in daily maintenance. Therefore, we propose a detachable printing press wall panel beam to solve this technical defect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a detachable printing press wall panel crossbeam.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable printing press wall panel crossbeam, including a crossbeam rod, with locking rods provided at the four corners of the left and right sides of the crossbeam rod, and threaded rods provided at the middle of the left and right sides of the crossbeam rod. The locking rods and the threaded rods both pass through the wall panel, with a locking nut provided on the outside of the threaded rods, and a rotating ring rotating concentrically on the inside of the locking nut. Connecting rods are provided at the upper and lower ends of the rotating rings, and a locking assembly is provided between the connecting rods and the locking rods.

[0006] By adopting the above technical solution, the locking rod and the threaded rod pass through the wall panel, and the locking nut is screwed into the threaded rod. This achieves the assembly and fixation of the beam and the wall panel, while the screwing of the locking nut drives the rotating ring and the connecting rod to move. At the same time, the locking component locks and fixes the beam and the wall panel, improving the stability of the connection between the beam and the wall panel and facilitating quick installation, fixation and disassembly.

[0007] As a preferred embodiment of this utility model, the outer surface of the rotating ring is provided with an annular groove concentric with the center, and the surface of the locking nut is provided with a sliding seat that rotates within the annular groove.

[0008] Using the above technical solution, the locking nut drives the sliding seat to rotate in the annular groove, ensuring the stability of the rotation between the rotating ring and the locking nut.

[0009] As a preferred embodiment of this utility model, the wall panel is provided with through holes for the locking rod and the threaded rod to pass through.

[0010] By adopting the above technical solution, the perforation facilitates the passage of the locking rod and the threaded rod.

[0011] As a preferred technical solution of this utility model, the locking assembly includes a movable rod that slides on the front and rear sides of the connecting rod, a stainless steel spring is provided between the movable rod and the connecting rod, the surface of the locking rod is provided with a mounting groove, a rack is provided in the mounting groove, and the other end of the movable rod is provided with a mating rack that meshes with the rack.

[0012] As a preferred technical solution of this utility model, the side of the mating rack facing the wall panel is an inclined surface, the contact surface between the rack and the inclined surface is also an inclined surface, and the inclined surfaces fit together. The mating rack and the surface of the rack opposite to the inclined surface are vertical surfaces.

[0013] Using the above technical solution, when the connecting rod moves, it drives the docking rack on the moving rod to move synchronously on the rack through the inclined surface. At the same time, the stainless steel spring adapts and elastically expands and contracts, allowing the moving rod to move within the connecting rod. The vertical setting after movement prevents the docking rack from moving back, thus achieving locking and fixing of the locking rod after movement.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This detachable printing press wall panel crossbeam uses a locking rod and a threaded rod to pass through the wall panel. A locking nut is screwed into the threaded rod, which allows the crossbeam and wall panel to be assembled and fixed at the same time. The screwing of the locking nut drives the rotating ring and connecting rod to move. At the same time, the locking component locks and fixes the crossbeam and wall panel, improving the stability of the connection. Compared with the existing welding method between the wall panel and the crossbeam, this design allows for quick installation and disassembly, facilitating maintenance. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 The detachable printing press wall panel crossbeam in this embodiment mainly includes a crossbeam rod 1, a wall panel 2, a locking rod 3, a threaded rod 4, a locking nut 5, a rotating ring 6, a connecting rod 7, and a locking assembly. Through the coordinated cooperation between the components, the crossbeam rod and the wall panel can be quickly installed and disassembled, which facilitates the daily maintenance of the printing press.

[0024] Crossbeam 1: As the main structure of the entire crossbeam, it serves to support and connect the wall panel 2. Locking rods 3 are welded to the four corners on the left and right sides, and a threaded rod 4 is welded to the middle of each side. The locking rods 3 and threaded rods 4 are both set perpendicular to the side of the crossbeam and are evenly distributed to ensure the stability of the connection.

[0025] Wall panel 2: The supporting base of the printing press, which has through holes for the locking rod 3 and threaded rod 4 to pass through. The position of the through holes corresponds to the position of the locking rod 3 and threaded rod 4 on the crossbeam 1, ensuring that the crossbeam can be accurately installed on the wall panel.

[0026] Locking rod 3: Used to insert into the perforation of the wall panel, serving as a preliminary positioning and fixing function. Its surface has an installation groove 10, in which a rack 11 is installed and fixed. The rack has regular triangular teeth to ensure the meshing effect with the mating rack.

[0027] Threaded rod 4: It has external threads for engaging with locking nut 5. The crossbeam rod is fixed to the wall panel by screwing in the thread. The length of the threaded rod is determined according to the actual installation requirements to ensure that the locking nut has enough screwing space.

[0028] Locking nut 5: A rotating ring 6 is rotatably connected to the inner surface of the locking nut 5. The specific connection method is as follows: an annular groove is opened on the outer surface of the rotating ring 6. A sliding seat that rotates in the annular groove is fixed on the surface of the locking nut 5. The sliding seat and the annular groove are in clearance fit to ensure that the rotating ring can rotate freely relative to the locking nut, and at the same time can move along the threaded rod with the locking nut.

[0029] Rotating ring 6: As a connecting component of connecting rod 7, connecting rod 7 is fixed at its upper and lower ends respectively. Connecting rod 7 is perpendicularly connected to rotating ring 6 by welding to ensure the connection is firm.

[0030] Link 7: A locking assembly is provided between it and the locking rod 3. Link 7 is a long strip structure, and movable rods 9 are slidably connected to its front and rear sides respectively.

[0031] Locking component:

[0032] Moving rod 9: Slidingly connected to connecting rod 7, with a stainless steel spring 8 fixed between them. One end of the stainless steel spring 8 is fixedly connected to the moving rod 9, and the other end is fixedly connected to the connecting rod 7, providing elastic restoring force for the moving rod 9.

[0033] The mating rack 12 is fixed to the other end surface of the moving rod 9 and meshes with the rack 11 in the mounting groove 10 on the surface of the locking rod 3. The side of the mating rack 12 facing the wall panel 2 is an inclined surface, and the contact surface between the rack 11 and the inclined surface is also an inclined surface, with the inclined surfaces fitting together. The surfaces of the mating rack 12 and the rack 11 opposite to the inclined surface are vertical surfaces. This structure allows the mating rack 12 to move synchronously on the rack 11 through the inclined surface when the connecting rod 7 moves. At the same time, the stainless steel spring 8 adapts to elastic extension and contraction, allowing the moving rod 9 to move within the connecting rod 7. After movement, the vertical surface setting can prevent the mating rack 12 from moving back, thus achieving locking and fixing of the locking rod 3.

[0034] Structural design principles and usage steps:

[0035] Align the locking rod 3 and threaded rod 4 on the crossbeam 1 with the through hole on the wall panel 2, insert the crossbeam 1 into the wall panel, so that the locking rod 3 and threaded rod 4 pass through the wall panel 2.

[0036] Screw the locking nut 5 onto the threaded rod 4. As the locking nut 5 is screwed in, it causes the rotating ring 6 and the connecting rod 7 to move together toward the wall panel 2.

[0037] During the movement of the connecting rod 7, the mating rack 12 on the moving rod 9 moves synchronously on the rack 11 through the inclined surface, while the stainless steel spring 8 is compressed and undergoes elastic deformation.

[0038] When the locking nut 5 is tightened into place, the vertical surfaces of the mating rack 12 and rack 11 abut against each other, preventing the mating rack 12 from moving back, thereby locking and fixing the locking rod 12, and thus firmly installing the crossbeam rod 1 on the wall panel 2.

[0039] Disassembly process:

[0040] Rotate the locking nut 5 in the opposite direction to make it move outward along the threaded rod 4, which in turn drives the rotating ring 6 and the connecting rod 7 to move outward.

[0041] During the movement of the connecting rod 7, the stainless steel spring 8 recovers its elastic deformation, pushing the moving rod 9 to move outward, and at the same time causing the docking rack 12 to separate from the rack 11, thus releasing the locking of the locking rod 12.

[0042] After the locking nut 5 is fully unscrewed, pull the crossbeam 1 off the wall panel 2 to complete the disassembly.

[0043] In summary, this detachable printing press wall panel beam, through its reasonable structural design and the coordinated cooperation between its components, enables the rapid installation and disassembly of the beam and wall panel. It has the advantages of simple structure, convenient operation, and stable connection, and can effectively solve the problem of the inability to disassemble and replace the welded fixed wall panel and beam in the existing technology, thus facilitating the daily maintenance and repair of the printing press.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
