Description

Technical Field

[0001] This utility model relates to the field of tent and parasol manufacturing, specifically an umbrella frame connector. Background Technology

[0002] Tents and parasols are generally foldable. To achieve this foldability, the frame needs to be composed of several rotatable rods. Connecting the rods requires first welding a connector to the top of the frame, then using rivets or screws to connect the rotatable rods through the connector's through-holes. The connector typically connects to three rods, requiring three connecting sections in different directions. Existing connectors consist of a bent M-shaped piece with a welded rib in the middle. The rib and the M-shaped piece have an overlapping connection (welded section). This requires a welding process during connector manufacturing, which is cumbersome. When connecting the connector to the frame, it needs to be welded again. Because of the overlapping connection when welding the rib, one end of the connector is thicker, making welding to the frame more difficult. Furthermore, the thicker end, due to the overlapping welded section, is difficult to weld tightly, causing the connector to easily detach during use, indicating a certain deficiency. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and solve the problems mentioned in the background art, and to provide an umbrella frame connector. The connector has an integrated structure with three connecting parts in three directions. It eliminates the need to weld a rib in the middle of the M-shaped part, reducing the trouble of manufacturing the connector. It can be directly stamped and bent in one piece, reducing the welding process and making production more convenient. The welding between the connector and the frame is also convenient. The welding between the connector and the frame is firm and has high stability.

[0004] The objective of this utility model is achieved through the following technical solution: an umbrella frame connector, comprising an M-shaped component. The M-shaped component includes a mating surface and through holes at both ends. Two protruding bent ribs form a connecting portion in the middle of the two mating surfaces of the M-shaped component. The two bent ribs are folded and matted together, and the ends of the bent ribs are bent angles. The two ends of the M-shaped component and the bent ribs form a connecting portion in three directions. The connector is an integral structure, eliminating the need to weld a rib block in the middle of the M-shaped component to form a whole. No welding is required during the manufacturing process of the connector; the protruding bent ribs form the connecting portion between the two mating surfaces, reducing welding steps and making the production of the connector more convenient.

[0005] The bending rib of the M-shaped part has a notch at the end. The notch weakens the rigidity of the bending angle of the M-shaped part, making it easier to bend and bond the middle part of the two mating surfaces of the M-shaped part to form a bending rib. It also makes the bonding gap between the two bending ribs smaller, and the bonding after bending is tighter, forming a stable overall structure. It is integrally molded and does not require welding a rib block.

[0006] The bending ribs of the M-shaped component have through holes, which allow for the installation of rotatable rods.

[0007] The M-shaped part has connecting screws in the through holes at both ends for connection with the rod.

[0008] The two mating surfaces of the M-shaped component can be welded together with the two end faces of the bracket to fix the M-shaped component to the upper end of the bracket. Since the two mating surfaces of the M-shaped component are of uniform thickness, the mating surfaces can be well welded and fixed to the upper end of the bracket during the welding process, making the welding process more convenient. The connection between the connector and the bracket is firmly welded and has high stability, avoiding the shortcomings of the prior art where one end of the mating surface is thicker and there are overlapping welding positions, resulting in weak welding.

[0009] This utility model has the following advantages: 1. The connector is an integrated structure, and the protruding bending rib can form the middle connecting part. There is no need to weld another rib in the middle of the M-shaped part, which reduces the trouble of connector manufacturing. It can be directly bent into one piece, reducing the welding process and making production more convenient; 2. The welding between the connector and the bracket is convenient and the welding between the connector and the bracket is firm and has high stability; 3. The bending rib of the M-shaped part has a notch at the end, which weakens the rigidity of the bending angle of the M-shaped part. It is easier to bend and fit the middle part of the two mating surfaces of the M-shaped part to form a bending rib, and also makes the mating gap between the two bending ribs smaller, the mating after bending is tighter, and forms a stable overall structure.

[0015] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0016] like Figure 1-2 In the existing technology shown, tents and parasols are generally foldable. To achieve foldability, the upper part of the product's frame 7 needs to be connected by several rotatable rods 8. The connection of the rods 8 requires first welding a connector to the upper part of the frame 7, and then connecting several rotatable rods through the through holes of the connector using rivets or connecting screws 9 (i.e., rotatable shaft connections). Since one connector typically needs to connect to three rods 8, three connecting parts with different vector directions are required to connect rods 8 in different directions. Existing connectors consist of a bent M-shaped part 1 with a reinforcing rib 4 welded in the middle. The reinforcing rib 4 and the M-shaped part... There will be an overlap 6 (i.e., the welding overlap) at the welding position 5 between parts 1. This requires a welding process during the manufacturing of the connector, which is troublesome. When connecting the entire connector to the bracket 7, it is necessary to attach the back of the connector 2 to the upper end of the bracket 7 again before welding. Since the overlap is already at the same position as the contact surface 2 when welding the rib 4, one end of the connector has a thicker contact surface 2. When welding it to the bracket 7, it is necessary to spot weld at the welding position 5, which is troublesome. Moreover, the thick overlap 6 is difficult to weld tightly, resulting in low firmness. This makes it easy for the entire connector to detach from the upper end of the bracket 7 during use, which has certain shortcomings.

[0017] like Figure 2-3 In this embodiment, an umbrella frame connector includes an M-shaped component 1. The M-shaped component 1 includes a mating surface 2 and through holes 3 at both ends. Two protruding bending ribs 11 form the middle connecting portion between the two mating surfaces 2 of the M-shaped component 1. The two bending ribs 11 are folded together and fitted together. The ends of the bending ribs 11 are bent at angles 13. The two ends of the M-shaped component 1 and the bending ribs 11 form the connecting portion in three directions. The connector is an integral structure, eliminating the need to weld a rib block 4 in the middle of the M-shaped component 1 to form a whole. No welding is required during the manufacturing process of the connector; the protruding bending ribs 11 are formed to obtain the connecting portion between the two mating surfaces 2, reducing welding steps and making connector production more convenient.

[0018] The bending rib 11 of the M-shaped part 1 has a notch 12 at its end. The notch 12 weakens the rigidity of the bending angle 13 of the M-shaped part, making it easier to bend and bond the middle part of the two mating surfaces 2 of the M-shaped part 1 to form the bending rib 11. It also makes the bonding gap between the two bending ribs 11 smaller, and the bonding after bending is tighter, forming a stable overall structure. It is integrally formed and does not require welding a rib block 4.

[0019] The bending rib 11 of the M-shaped part 1 is provided with a through hole 3, which allows a rotatable rod 8 to be installed.

[0020] The M-shaped part 1 can be connected to the rod 8 through the through holes 3 at both ends by connecting screws 9.

[0021] The two mating surfaces 2 of the M-shaped part 1 can fit with the two end faces of the bracket 7. Then, spot welding is performed on the mating surfaces 2 to weld and fix the M-shaped part 1 to the upper end of the bracket 7. Since the thickness of the two mating surfaces 2 of the M-shaped part 1 is uniform, the mating surfaces 2 can be well welded and fixed to the upper end of the bracket 7 during the welding process. The welding process is also more convenient. The weld between the connector and the bracket 1 is firm and has high stability. This avoids the shortcomings of the prior art, where one end of the mating surface 2 is thicker and there are overlapping welding positions, which cause the weld to be weak.
