Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, and in particular to a lightweight connecting flange for folding conveying equipment. Background Technology

[0002] Foldable conveyor equipment is a material conveying device that can shrink and unfold through a folding structure. It is mainly used for continuous material handling operations in various scenarios.

[0003] However, in some existing technologies, in scenarios such as logistics and warehousing where equipment needs to be folded and handled frequently, operators need to spend more manpower on folding operations, which reduces work efficiency. At the same time, although the overall volume of the equipment is reduced after folding, the protrusion of the flange itself at the bending or overlapping process can lead to an increase in area or problems with the folded parts not fitting properly.

[0004] Therefore, this utility model provides a lightweight connecting flange for folding conveyor equipment. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a lightweight connecting flange for folding conveyor equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight connecting flange for a folding conveyor, comprising a flange assembly, wherein the flange assembly comprises an upper flange block and a lower flange block, wherein the upper flange block is internally rotatably connected to a plurality of connecting shafts one, and the lower flange block is internally rotatably connected to a plurality of connecting shafts two.

[0007] A pressurizing connection assembly includes a groove formed inside a lower flange block, a connecting hollow column slidably connected inside the groove, and a piston fixedly connected inside the connecting hollow column.

[0008] In a preferred embodiment, a connecting nut is fixedly connected to the outer side of the piston.

[0009] In a preferred embodiment, the upper flange block is internally threaded with connecting bolts matching the number of connecting shafts, and the lower flange block is fixedly connected to the connecting nut by connecting bolts.

[0010] In a preferred embodiment, the outer thread of the connecting bolt is connected to the connecting nut.

[0011] In a preferred embodiment, the outer side of the connecting nut is slidably connected to the inside of the lower flange block.

[0012] In a preferred embodiment, a sealing gasket is provided between the upper flange block and the lower flange block, with the top end of the sealing gasket contacting the bottom end of the upper flange block and the bottom end of the sealing gasket contacting the top end of the lower flange block.

[0013] In a preferred embodiment, the outer side of the piston is slidably connected to a groove inside the lower flange block.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This invention utilizes the axial force of the connecting bolt's thread to drive the connecting nut to slide along the groove, thereby causing the piston to move within the hollow connecting column and compress the cavity to generate a reaction force. This reaction force enhances the tightness of the connection between the connecting nut and the connecting bolt and is transmitted to the upper and lower flange blocks to compress the sealing gasket. This design achieves a high-sealing connection under dynamic pressure and rapid disassembly and assembly of a lightweight structure, effectively reducing the manpower consumption of operators when folding the equipment and improving work efficiency.

[0025] 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.

[0026] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: a lightweight connecting flange for a folding conveyor, including a flange assembly 1. The flange assembly 1 includes an upper flange block 11 and a lower flange block 13. The upper flange block 11 is rotatably connected to a plurality of connecting shafts 12, and the lower flange block 13 is rotatably connected to a plurality of connecting shafts 14. A sealing gasket 3 is provided between the upper flange block 11 and the lower flange block 13. The top end of the sealing gasket 3 contacts the bottom end of the upper flange block 11, and the bottom end of the sealing gasket 3 contacts the top end of the lower flange block 13.

[0027] The upper flange block 11 and the lower flange block 13 serve as the core of the connecting structure, used to connect two key components of the folding conveyor, and undertake the functions of connection and force transmission. Both the connecting shaft 12 and the connecting shaft 14 are rotation fulcrums. The connecting shaft 12 provides a rotational connection between the upper flange block 11 and the upper structure of the equipment, and the connecting shaft 14 provides a rotational connection between the lower flange block 13 and the lower structure of the equipment. The sealing gasket 3 fills the gap between the upper flange block 11 and the lower flange block 13 and fits the contact surface of the two blocks through its own deformation, thereby achieving a seal at the connection of the upper and lower flange blocks 13, preventing leakage of conveyed materials, and ensuring conveying efficiency.

[0028] like Figure 3 - Figure 5 As shown, the pressurizing connection assembly 2 includes a groove 21 formed inside the lower flange block 13. A connecting hollow column 22 is slidably connected inside the groove 21. A piston 23 is fixedly connected inside the connecting hollow column 22. A connecting nut 24 is fixedly connected to the outside of the piston 23. A connecting bolt 15 matching the number of connecting shafts 12 is threaded inside the upper flange block 11. The lower flange block 13 is fixedly connected to the connecting nut 24 by the connecting bolt 15. The outside of the connecting bolt 15 is threadedly connected to the connecting nut 24. The outside of the connecting nut 24 is slidably connected inside the lower flange block 13. The outside of the piston 23 is slidably connected to the groove 21 inside the lower flange block 13.

[0029] The slide groove 21 is located inside the lower flange block 13, providing a sliding guide track for connecting the hollow column 22 and the piston 23, restricting their movement to only axial direction. This guiding action ensures the stability of the movement trajectory of the connecting hollow column 22 and the piston 23, preventing structural jamming or pressure imbalance caused by misalignment, and ensuring reliable pressurization. The piston 23 is fixed inside the connecting hollow column 22, forming a closed pressure chamber. This chamber acts as an intermediate carrier for pressure transmission, converting the movement of the piston 23 into pressure changes within the chamber. It provides installation space for the piston 23 and forms a pressure chamber, ensuring the pressurization function is realized and improving connection tightness. The piston 23 slides within the connecting hollow column 22 and the slide groove 21, compressing the space inside the connecting hollow column 22 through axial movement. The space utilizes the pressure reaction force to enhance the tightness of the connection between the connecting nut 24 and the connecting bolt 15, indirectly increasing the pressing force of the upper and lower flange blocks 13, making the sealing gasket 3 more tightly squeezed and strengthening the sealing effect. The connecting nut 24 and the connecting bolt 15 are threaded together, receiving the tightening force of the bolt and transmitting it to the piston 23. At the same time, it slides along the inside of the lower flange block 13, converting the axial force of the bolt into the pressurizing power of the piston 23. The threaded connection enables a detachable connection, which is convenient for installation, maintenance and adjustment. The connecting bolt 15 fixes the upper flange block 11 and the lower flange block 13 through the threaded connection. When tightened, it provides axial driving force, driving the connecting nut 24 and the piston 23 to move and triggering the pressurization process.

[0030] like Figure 1 - Figure 5 As shown:

[0031] In use: First, the connecting bolt 15 is screwed into the upper flange block 11 and tightened continuously. The axial force of its thread directly acts on the connecting nut 24, which in turn drives the connecting nut 24 to slide axially along the inner slide groove 21 of the lower flange block 13. This causes the piston 23 to move synchronously within the slide groove 21 and the connecting hollow column 22, thereby compressing the inner volume of the connecting hollow column 22 and forming a reaction force that closes the pressure chamber. This pressure acts in the opposite direction on the connecting nut 24, making its thread fit with the connecting bolt 15 doubled. This then transmits the pressurized axial force to the upper flange block 11 and the lower flange block 13. Finally, the sealing gasket 3 is uniformly compressed in both directions, achieving a high-sealing connection under dynamic pressurization and rapid disassembly and assembly of a lightweight structure.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
