Description

Technical Field

[0001] This invention belongs to the field of structural components technology, and particularly relates to a frame and conveyor line. Background Technology

[0002] In the manufacturing of industrial aluminum profile frames, machine equipment frames, automated production lines, and other products, it is often necessary to connect multiple profiles. Currently, common connection methods include welding, bolt and nut connections, and connections using specialized angle brackets.

[0003] In existing technologies, when using ordinary bolts with independent nuts for connection, the nuts cannot be effectively positioned within the profile groove or behind the connecting piece. When tightening the bolts, the nuts tend to rotate, leading to assembly difficulties. Tools are needed to secure the nuts, making the process cumbersome and inefficient. Furthermore, under vibration or cyclic loading conditions, ordinary nuts are prone to loosening, causing connection failure and affecting the safety and reliability of the structure. Summary of the Invention

[0004] The main objective of this invention is to provide a frame and conveyor line to improve the reliability of the connection between profiles.

[0005] The present invention achieves the above objectives through the following technical solutions: A frame includes a vertical profile, a horizontal profile, a base plate, a connecting structure, a first screw, and a third screw. The outer periphery of the vertical profile has a T-slot. One end face of the horizontal profile is attached to the side of the vertical profile, and a vertical mounting hole is provided on the horizontal profile. The base plate is located below the vertical profile and the horizontal profile, and threaded holes are provided on the surface of the base plate. The connecting structure includes a base plate, a first connecting plate, a first nut, and a horizontal plate. At least one first through hole is formed on the base plate. The first connecting plate is located in a T-slot on one side of the vertical profile. The first connecting plate is connected to the base plate. The plate surface of the first connecting plate is opposite to the plate surface of the base plate and is arranged at intervals. A first connecting hole is formed on the first connecting plate. The first nut is riveted to the first connecting hole. The screw hole of the first nut is arranged corresponding to a first through hole on the base plate. The horizontal plate is connected to one side of the base plate. The plate surface of the horizontal plate is arranged at an angle to the plate surface of the base plate. At least one second through hole is formed on the horizontal plate. The horizontal plate is in contact with the top surface of the horizontal profile. The first screw passes through a first through hole on the substrate and connects to the first nut on the first connecting plate to lock the substrate and the T-slot of the vertical profile; the third screw passes through the second through hole on the horizontal plate and the mounting hole of the horizontal profile and connects to the bottom plate by thread.

[0006] Furthermore, the connection structure also includes a second connecting plate, a second nut, and a second screw. The second connecting plate is connected to the substrate. The surface of the second connecting plate is opposite to the surface of the substrate and is arranged at intervals. A second connecting hole is opened on the second connecting plate. The second connecting plate and the first connecting plate are both located on the same side of the substrate. The second nut is press-fitted onto the second connecting hole, and the screw hole of the second nut is arranged corresponding to another first through hole on the substrate; the second screw passes through another first through hole on the substrate and connects to the second nut on the second connecting plate to lock the substrate and the T-slot of the vertical profile.

[0007] Furthermore, the first connecting plate is connected to the substrate by an upper bending plate. The width of the first connecting plate is greater than the width of the T-slot opening of the vertical profile, and the width of the upper bending plate is less than the width of the T-slot opening of the vertical profile. The second connecting plate is connected to the base plate via a lower bending plate. The width of the second connecting plate is greater than the width of the T-slot opening of the vertical profile, while the width of the lower bending plate is less than the width of the T-slot opening of the vertical profile.

[0008] Furthermore, the substrate has an upper punching opening, and the substrate body is punched and bent to form a first connecting plate, an upper bending plate, and an upper punching opening; the substrate has a lower punching opening, and the substrate body is punched and bent to form a second connecting plate, a lower bending plate, and a lower punching opening.

[0009] Furthermore, the two connecting structures are arranged in a mirror symmetrical manner, the sides of the substrates of the two connecting structures are connected, the substrates of the two connecting structures are formed by bending a single plate, and the surfaces of the substrates of the two connecting structures are arranged at an angle. The first connecting plate of one connecting structure is located in a T-slot on one side of the vertical profile, and the first connecting plate of the other connecting structure is located in a T-slot on the other side of the vertical profile.

[0010] Furthermore, the frame also includes longitudinal profiles, and two transverse plates are respectively attached to the top surfaces of the transverse and longitudinal profiles; Another third screw passes through the second through hole on the horizontal plate, the mounting hole of the longitudinal profile, and the threaded hole on the base plate.

[0011] Furthermore, a third through hole is formed on the substrate, and threaded holes are formed on both sides of the bottom plate, with the threaded holes on both sides of the bottom plate corresponding to the two third through holes. The frame also includes two fourth screws. One fourth screw passes through a third through hole on a substrate and connects to a threaded hole on one side of the base plate. The other fourth screw passes through a third through hole on another substrate and connects to a threaded hole on the other side of the base plate.

[0012] Furthermore, two second through holes are spaced apart on the horizontal plate, and a third through hole on the substrate and the two second through holes on the horizontal plate are arranged in a triangular shape.

[0013] Furthermore, the substrate is bent to form a horizontal plate, which is located on the same side of the substrate as the first connecting plate and between the first connecting plate and the second connecting plate.

[0014] The present invention also provides a conveyor line including the aforementioned frame.

[0015] Compared with the prior art, the present invention has the following technical effects: The first screw passes through the first through hole on the substrate and connects to the first nut on the first connecting plate, locking the substrate in the T-slot of the vertical profile. At the same time, the third screw passes through the second through hole on the horizontal plate and the mounting hole of the horizontal profile and connects to the base plate by thread, realizing the quick and reliable fixing between the vertical profile, the horizontal profile and the base plate.

Detailed Implementation

[0017] The following is combined Figures 1 to 15 Embodiments of the present invention will be described.

[0018] Example 1 like Figure 1 As shown, this embodiment provides a connection structure, which includes a base plate 31, a first connecting plate 32, and a first nut 33. At least one first through hole 311 is formed on the base plate 31. The first connecting plate 32 is connected to the base plate 31, and the plate surface of the first connecting plate 32 is opposite to and spaced apart from the plate surface of the base plate 31. A first connecting hole is formed on the first connecting plate 32. The first nut 33 is riveted and fixed to the first connecting hole, and the screw hole of the first nut 33 is arranged corresponding to a first through hole 311 on the base plate 31.

[0019] The first connecting plate 32 and the first nut 33 can be placed in the T-slot of the profile. During the process of locking the first nut 33 through the first through hole 311 of the base plate 31 and the first connecting hole of the first connecting plate 32, the distance between the first connecting plate 32 and the base plate 31 decreases, and the first connecting plate 32 and the base plate 31 can clamp the T-slot of the profile. This solves the problem of the nut not being able to be positioned and easily rotating in the prior art. No auxiliary tools are needed to fix the nut during assembly, which improves the assembly efficiency. At the same time, the riveting connection is firm, vibration-resistant and anti-loosening, which improves the reliability of the connection and the structural strength.

[0020] Example 2 like Figure 1 As shown, this embodiment provides a connection structure, which includes a base plate 31, a first connecting plate 32, and a first nut 33. At least one first through hole 311 is formed on the base plate 31. The first connecting plate 32 is connected to the base plate 31, and the plate surface of the first connecting plate 32 is opposite to and spaced apart from the plate surface of the base plate 31. A first connecting hole is formed on the first connecting plate 32. The first nut 33 is riveted and fixed to the first connecting hole, and the screw hole of the first nut 33 is arranged corresponding to a first through hole 311 on the base plate 31.

[0021] The connection structure also includes a second connecting plate 34 and a second nut 35. The second connecting plate 34 is connected to the substrate 31. The plate surface of the second connecting plate 34 is opposite to the plate surface of the substrate 31 and is arranged at intervals. A second connecting hole is opened on the second connecting plate 34. The second connecting plate 34 and the first connecting plate 32 are both located on the same side of the substrate 31. The second nut 35 is riveted to the second connecting hole. The screw hole of the second nut 35 is arranged corresponding to another first through hole 311 on the substrate 31.

[0022] By setting two independent connecting plates and corresponding rivet nuts on the same side of the substrate 31, it can be connected to two profiles in different directions or two different slots of the same profile at the same time, which enhances the connection strength between the connecting structure and the profile.

[0023] Example 3 like Figure 1 As shown, this embodiment provides a connection structure, which includes a base plate 31, a first connecting plate 32, and a first nut 33. At least one first through hole 311 is formed on the base plate 31. The first connecting plate 32 is connected to the base plate 31, and the plate surface of the first connecting plate 32 is opposite to and spaced apart from the plate surface of the base plate 31. A first connecting hole is formed on the first connecting plate 32. The first nut 33 is riveted and fixed to the first connecting hole, and the screw hole of the first nut 33 is arranged corresponding to a first through hole 311 on the base plate 31.

[0024] The first connecting plate 32 is connected to the substrate 31 by an upper bending plate 36, the width of which is smaller than the width of the first connecting plate 32.

[0025] The width of the upper bending plate 36 is smaller than that of the connecting plate, which can create a clearance space between the connecting plate and the base plate 31, making it easier to install and adjust. At the same time, it reduces the amount of material used, lightens the structural weight, and facilitates the realization of the stamping process.

[0026] It should be noted that the width of the upper bending plate 36 is smaller than the width of the T-slot of the profile, so that the first connecting plate 32 can be placed in the T-slot along the length of the profile. The width of the first connecting plate 32 is larger than the width of the T-slot of the profile, so that the first connecting plate 32 and the base plate 31 can clamp the wall of the T-slot of the profile.

[0027] Example 4 like Figure 1 As shown, this embodiment provides a connection structure, which includes a base plate 31, a first connecting plate 32, and a first nut 33. At least one first through hole 311 is formed on the base plate 31. The first connecting plate 32 is connected to the base plate 31, and the plate surface of the first connecting plate 32 is opposite to and spaced apart from the plate surface of the base plate 31. A first connecting hole is formed on the first connecting plate 32. The first nut 33 is riveted and fixed to the first connecting hole, and the screw hole of the first nut 33 is arranged corresponding to a first through hole 311 on the base plate 31.

[0028] The connection structure also includes a second connecting plate 34 and a second nut 35. The second connecting plate 34 is connected to the substrate 31. The plate surface of the second connecting plate 34 is opposite to the plate surface of the substrate 31 and is arranged at intervals. A second connecting hole is opened on the second connecting plate 34. The second connecting plate 34 and the first connecting plate 32 are both located on the same side of the substrate 31. The second nut 35 is riveted to the second connecting hole. The screw hole of the second nut 35 is arranged corresponding to another first through hole 311 on the substrate 31.

[0029] The first connecting plate 32 is connected to the base plate 31 by the upper bending plate 36. The width of the first connecting plate 32 is greater than the width of the T-slot opening of the profile, and the width of the upper bending plate 36 is less than the width of the T-slot opening of the profile. The second connecting plate 34 is connected to the base plate 31 by a lower bending plate 37. The width of the second connecting plate 34 is greater than the width of the T-slot opening of the profile, and the width of the lower bending plate 37 is less than the width of the T-slot opening of the profile.

[0030] The width of the lower bending plate 37 is smaller than the width of the second connecting plate 34, which can form a clearance space between the second connecting plate 34 and the base plate 31, making it easier to install and adjust. At the same time, it reduces the amount of material used, lightens the structural weight, and is conducive to the realization of the stamping process.

[0031] Example 5 Based on the aforementioned embodiments, in this embodiment, the substrate 31 has an upper punching opening 313, and the substrate 31 is punched and bent to form a first connecting plate 32, an upper bending plate 36, and an upper punching opening 313; or, the substrate 31 has a lower punching opening 314, and the substrate 31 is punched and bent to form a second connecting plate 34, a lower bending plate 37, and a lower punching opening 314.

[0032] like Figures 1 to 4 As shown, both the upper punching opening 313 and the lower punching opening 314 are through holes. The outlines of the through holes of the upper punching opening 313 and the lower punching opening 314 can be square, circular, or elliptical, etc.

[0033] like Figures 5 to 8 As shown, both the upper punching opening 313 and the lower punching opening 314 are notched.

[0034] The integrated punching and bending forming process eliminates the need for welding or additional parts, simplifying the manufacturing process and reducing production costs. At the same time, it ensures the relative positional accuracy of the connecting plate and the base plate 31, improving the consistency and reliability of the product.

[0035] Example 6 like Figure 1 As shown, this embodiment provides a connection structure, which includes a base plate 31, a first connecting plate 32, and a first nut 33. At least one first through hole 311 is formed on the base plate 31. The first connecting plate 32 is connected to the base plate 31, and the plate surface of the first connecting plate 32 is opposite to and spaced apart from the plate surface of the base plate 31. A first connecting hole is formed on the first connecting plate 32. The first nut 33 is riveted and fixed to the first connecting hole, and the screw hole of the first nut 33 is arranged corresponding to a first through hole 311 on the base plate 31.

[0036] The connecting structure also includes a horizontal plate 38, which is connected to one side of the substrate 31. The surface of the horizontal plate 38 and the surface of the substrate 31 are arranged at an angle. At least one second through hole 381 is opened on the horizontal plate 38.

[0037] The horizontal plate 38 provides a connection interface in another direction, enabling the connection structure to be fixed in the vertical direction or connected to other components at the same time, expanding the function of the connection structure and making it suitable for the assembly of complex structures such as racks.

[0038] In a further preferred embodiment, the connection structure further includes a second connecting plate 34 and a second nut 35. The second connecting plate 34 is connected to the substrate 31, and the plate surface of the second connecting plate 34 is opposite to and spaced apart from the plate surface of the substrate 31. A second connecting hole is formed on the second connecting plate 34, and the second connecting plate 34 and the first connecting plate 32 are both located on the same side of the substrate 31. The second nut 35 is riveted and fixed to the second connecting hole, and the screw hole of the second nut 35 is arranged corresponding to another first through hole 311 on the substrate 31.

[0039] The horizontal plate 38 and the first connecting plate 32 are both located on the same side of the base plate 31, and the horizontal plate 38 is located between the first connecting plate 32 and the second connecting plate 34.

[0040] The horizontal plate 38 is located between the two connecting plates, with a compact layout that avoids interference. This facilitates multi-directional connections within a limited space, improving the integration of the connection structure and the utilization of space.

[0041] The substrate 31 is bent to form a horizontal plate 38, and the surface of the substrate 31 is perpendicular to the surface of the horizontal plate 38. Two second through holes 381 are opened at intervals on the horizontal plate 38, and a third through hole 312 opened on the substrate 31 and the two second through holes 381 on the horizontal plate 38 are arranged in a triangular shape.

[0042] The substrate 31 and the horizontal plate 38 are bent perpendicularly to ensure the directional accuracy of the connection; the triangular through-hole layout forms a stable stress structure, which improves the torsional and tensile resistance of the connection node and enhances the overall stability of the connection.

[0043] Example 7 like Figure 2 , Figure 3 and Figure 4 As shown, this embodiment is a profile connector, which includes the connection structure of any of the aforementioned embodiments. The two connection structures are arranged in a mirror symmetrical manner, and the base plates 31 of the two connection structures are connected on the sides.

[0044] The mirror-symmetric double connection structure can connect two vertical profiles simultaneously, achieving right-angle or T-shaped connections. It is suitable for scenarios where multiple profiles intersect, such as at the corners of the frame, improving connection efficiency and the stability of the overall frame.

[0045] The two connecting substrates 31 are formed by bending a single plate, and the included angle between the surfaces of the two connecting substrates 31 is 30° to 120°. Specifically, it can be 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, or 120°.

[0046] The one-piece bending process ensures the positional accuracy and strength of the two connecting structures; the included angle is adjustable over a wide range, which can adapt to the frame connection requirements of different angles (such as diagonal braces and non-right-angle frames), thus improving the versatility and applicability of the connectors.

[0047] Example 8 like Figures 9 to 15 As shown, this embodiment provides a frame, which includes a vertical profile 10a, a horizontal profile 10b, a base plate 20, a connecting structure, a first screw 11, and a third screw 13. The outer periphery of the vertical profile 10a has a T-slot; one end face of the horizontal profile 10b is in contact with the side of the vertical profile 10a, and a vertical mounting hole is provided on the horizontal profile 10b; the base plate 20 is located below the vertical profile 10a and the horizontal profile 10b, and threaded holes are provided on the surface of the base plate 20. The connecting structure includes a base plate 31, a first connecting plate 32, a first nut 33, and a horizontal plate 38. At least one first through hole 311 is formed on the base plate 31. The first connecting plate 32 is located in a T-groove on one side of the vertical profile 10a. The first connecting plate 32 is connected to the base plate 31. The plate surface of the first connecting plate 32 is opposite to the plate surface of the base plate 31 and is arranged at intervals. A first connecting hole is formed on the first connecting plate 32. The first nut 33 is riveted to the first connecting hole. The screw hole of the first nut 33 is arranged corresponding to a first through hole 311 on the base plate 31. The horizontal plate 38 is connected to one side of the base plate 31. The plate surface of the horizontal plate 38 is arranged at an angle to the plate surface of the base plate 31. At least one second through hole 381 is formed on the horizontal plate 38. The horizontal plate 38 is in contact with the top surface of the horizontal profile 10b. The first screw 11 passes through a first through hole 311 on the substrate 31 and is connected to the first nut 33 on the first connecting plate 32 to lock the substrate 31 and the T-slot of the vertical profile 10a; the third screw 13 passes through the second through hole 381 on the horizontal plate 38 and the mounting hole of the horizontal profile 10b and is threaded to the base plate 20.

[0048] The first screw passes through the first through hole on the base plate 31 and connects to the first nut on the first connecting plate, locking the base plate 31 into the T-slot of the vertical profile 10a. This eliminates the need for additional holes in the vertical profile 10a, thus avoiding a decrease in the strength of the vertical profile 10a. In addition, the anti-loosening properties of the T-slot and the press-fit nut ensure the long-term reliability of the frame under vibration.

[0049] While locking the substrate 31 to the T-slot of the vertical profile 10a, the third screw passes through the second through hole 381 on the horizontal plate 38 and the mounting hole of the horizontal profile 10b to the base plate 20, thereby achieving rapid fixation of the horizontal profile 10b and the vertical profile 10a on the base plate 20. The assembly is simple and can be automated.

[0050] Example 9 Based on Embodiment 8, the connection structure of this embodiment further includes a second connecting plate 34, a second nut 35, and a second screw 12. The second connecting plate 34 is connected to the substrate 31. The plate surface of the second connecting plate 34 is opposite to and spaced apart from the plate surface of the substrate 31. A second connecting hole is opened on the second connecting plate 34. The second connecting plate 34 and the first connecting plate 32 are both located on the same side of the substrate 31. The second nut 35 is pressed and fixed on the second connecting hole, and the screw hole of the second nut 35 is arranged corresponding to another first through hole 311 on the substrate 31; the second screw 12 passes through another first through hole 311 on the substrate 31 and connects to the second nut 35 on the second connecting plate 34 to lock the substrate 31 and the T-slot of the vertical profile 10a.

[0051] The base plate is locked from the same side of the T-slot of the vertical profile through two connection points, which significantly improves the connection strength and torsional resistance between the connection structure and the vertical profile, prevents the base plate from deflecting or loosening during use, and is suitable for frames under heavy loads or vibration conditions.

[0052] The first connecting plate 32 is connected to the base plate 31 by the upper bending plate 36. The width of the first connecting plate 32 is greater than the width of the T-slot opening of the vertical profile 10a, and the width of the upper bending plate 36 is less than the width of the T-slot opening of the vertical profile 10a. The second connecting plate 34 is connected to the base plate 31 by a lower bending plate 37. The width of the second connecting plate 34 is greater than the width of the T-slot opening of the vertical profile 10a, and the width of the lower bending plate 37 is less than the width of the T-slot opening of the vertical profile 10a.

[0053] The first connecting plate 32 can smoothly enter the T-slot and form a locking position within the slot, while the upper bent plate portion will not interfere with the T-slot wall. This structure ensures both smooth assembly and prevents the connecting plate from coming out of the slot after locking, thus improving the safety and reliability of the connection.

[0054] The substrate 31 has an upper punching opening, and the substrate 31 is punched and bent to form a first connecting plate 32, an upper bending plate 36 and an upper punching opening; the substrate 31 has a lower punching opening, and the substrate 31 is punched and bent to form a second connecting plate 34, a lower bending plate 37 and a lower punching opening.

[0055] The substrate 31 is bent to form a horizontal plate 38. The horizontal plate 38 and the first connecting plate 32 are located on the same side of the substrate 31, and the horizontal plate 38 is located between the first connecting plate 32 and the second connecting plate 34.

[0056] The entire connection structure is compact and integrated, with all functional components completed by bending on the same plate. This layout not only reduces the number of parts and assembly steps, but also avoids spatial interference between the horizontal plate 38 and the first connecting plate 32, facilitating installation and adjustment within narrow profile slots.

[0057] Example 10 Based on Embodiment 8, this embodiment has two connection structures, which are arranged in a mirror symmetrical manner. The substrates 31 of the two connection structures are connected on the sides. The substrates 31 of the two connection structures are formed by bending a single plate. The surfaces of the substrates 31 of the two connection structures are arranged at an angle. The first connecting plate 32 of one connecting structure is located in the T-slot on one side of the vertical profile 10a, and the first connecting plate 32 of the other connecting structure is located in the T-slot on the other side of the vertical profile 10a.

[0058] The two connecting structures are locked from the T-slots on both sides of the vertical profile 10a. This double-sided clamping structure can balance the force, greatly improving the frame's resistance to lateral forces and torsion, and is especially suitable for applications subject to complex loads.

[0059] The frame also includes a longitudinal profile 10c, and two transverse plates 38 that are respectively attached to the top surfaces of the transverse profile 10b and the longitudinal profile; A third screw 13 passes through the second through hole 381 on the horizontal plate 38 and the mounting hole of the transverse profile 10b to be threadedly connected to the base plate 20. Another third screw 13 passes through the second through hole 381 on the horizontal plate 38 and the mounting hole of the longitudinal profile 10c to be threadedly connected to the base plate 20.

[0060] The technical solution implemented here achieves rapid fixation through profile connectors and base plate 20.

[0061] By using two horizontal plates on the connecting structure to affix to the top surfaces of the transverse profile 10b and the longitudinal profile 10c respectively, and simultaneously fixing both to the base plate 20 via a third screw, a three-dimensional connection is achieved between the vertical profile 10a, the transverse profile 10b, the longitudinal profile 10c and the base plate 20. This structure gives the frame high rigidity and stability in both horizontal and vertical directions, making it suitable for constructing frame-type conveyor lines or workbenches.

[0062] Example 11 Based on Embodiment 10, a third through hole 312 is formed on the substrate 31 of this embodiment, and threaded holes are formed on both adjacent sides of the bottom plate 20. The threaded holes on both sides of the bottom plate 20 correspond to the two third through holes 312. The frame also includes two fourth screws 14. One fourth screw 14 passes through a third through hole 312 on a substrate 31 and is connected to a threaded hole on one side of the base plate 20. The other fourth screw 14 passes through a third through hole 312 on another substrate 31 and is connected to a threaded hole on the other side of the base plate 20.

[0063] A third through hole is made on the base plate 31, and the connecting structure is directly fixed to the threaded holes on the adjacent sides of the base plate using the fourth screw 14, forming a secondary reinforcement. This structure not only presses the transverse profile with the horizontal plate 38, but also improves the vibration resistance and positional accuracy of the entire frame through the direct connection between the base plate 31 and the base plate 20, preventing the connection from loosening after long-term use.

[0064] Two second through holes 381 are spaced apart on the horizontal plate 38, and a third through hole 312 is formed in a triangular arrangement with the two second through holes 381 on the horizontal plate 38.

[0065] The triangular structure has the highest geometric stability, which makes the connecting structure form a stable three-point support on the base plate, effectively resisting the torque in all directions and preventing the frame from tilting or deforming. It is especially suitable for conveyor line frames with high flatness requirements.

[0066] Example 12 A conveyor line includes a connection structure provided in any one of embodiments one to six, a profile connector provided in embodiment seven, or a frame provided in any one of embodiments eight to eleven.

[0067] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
