[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0020] See also Figure 1~Figure 2, the utility model embodiment includes:
[0021] like Figure 1 The frame pipe anti-bending connection structure shown includes: a first pipe 1, a second pipe 2, an anti-bending cylinder 3, a latch 5 and an elastic cylinder 4. One end of the first pipe 1 is connected to one end of the second pipe 2. In this embodiment, the cross-sectional specifications of the first pipe 1 and the second pipe 2 are the same, and the integrity is good after concentric docking.
[0022] The anti-bending cylinder 3 is arranged on the inner side of the first pipe fitting 1 and extends into the second pipe fitting 2. In this embodiment, the outer wall of the anti-bending cylinder 3 fits tightly with the inner walls of the first pipe fitting 1 and the second pipe fitting 2, thereby ensuring the concentricity of the first pipe fitting 1 and the second pipe fitting 2.
[0023] The wall thickness of the anti-bending cylinder 3 is greater than that of the first pipe 1, which is beneficial to improving the anti-bending strength of the connection. The first pipe 1 and the second pipe 2 are both made of round tubes or square tubes, and steel tubes or aluminum alloy tubes are selected. The anti-bending cylinder 3 can be made of steel tubes or aluminum alloy tubes, and has high structural strength.
[0024] like Figure 2 As shown, the first pipe fitting 1 and the second pipe fitting 2 are respectively provided with a first positioning hole 7 pointing to the anti-bending cylinder 3, and the anti-bending cylinder 3 is provided with a second positioning hole 8 corresponding to the first positioning hole 7 one by one. The latch 5 is arranged in the first positioning hole 7 and extends into the second positioning hole 8. The latch 5 is utilized to realize the axial limitation of the anti-bending cylinder 3 on the first pipe fitting 1 and the second pipe fitting 2 to avoid the problem of loosening.
[0025] In order to improve the stability of the pin 5, a limit member 6 is provided at the inner end of the pin 5 and is located inside the anti-bending cylinder 3. In this embodiment, the limit member 6 adopts a disc structure, and the diameter of the pin 5 is smaller than the diameter of the limit member 6, so that the pin 5 is limited in outward movement.
[0026] In order to prevent the pin 5 from moving inward and loosening, the elastic cylinder 4 is concentrically arranged in the anti-bending cylinder 3. In this embodiment, the elastic cylinder 4 uses a section of elastic rubber cylinder to elastically support the limiter 6 to improve the stability after assembly. The outer diameter of the elastic cylinder 4 corresponds to the inner diameter of the anti-bending cylinder 3, and the fit is tight.
[0027] During disassembly, a round rod is used to press the latch 5 from the outside, and a squeezing force is applied to the elastic cylinder 4 through the limiter 6, so that the elastic cylinder 4 is elastically deformed, and the latch 5 withdraws from the first positioning hole 7, so that the first pipe 1 and the second pipe 2 can be separated, and the operation is simple.
[0028] A positioning groove 9 corresponding to the limiting member 6 is concavely arranged on the outer circle of the elastic cylinder 4, which can not only limit the limiting member 6, but also realize axial limitation of the elastic cylinder 4 in the anti-bending cylinder 3 through the cooperation between the limiting member 6 and the positioning groove 9, thereby avoiding the problem of axial movement and maintaining a stable structure.
[0029] like Figure 2 As shown, the number of the first positioning holes 7 is at least 2, and the first positioning holes 7 are circumferentially spaced and distributed on the first pipe 1 and the second pipe 2, respectively, and multiple latches 5 can be installed for locking, and the structure is stable. In this embodiment, the positioning groove 9 adopts an annular groove structure, which has good adaptability to the position of the limiter 6 in the circumferential direction of the elastic cylinder 4. One circle of positioning grooves 9 can simultaneously meet the limit of multiple limiters 6 in one circle, and the structure is simple.
[0030] In summary, the utility model discloses a bending-resistant connection structure for a frame pipe, which can realize the docking of two pipes, improve the bending strength and structural stability after assembly, do not require welding or bolt connection, are easy to disassemble and assemble, are suitable for use in the frame, and improve the structural simplicity of the frame.
