[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Thus, features defined as "first" or "second" may explicitly or implicitly include at least one of these features.

[0030] from Figure 1 as well as Figure 2It can be seen that the connection component of the present invention includes a buckle 1, which can be made of high-strength structural steel Q355B. The high-strength structural steel Q355B has a high yield strength and tensile strength range, and good plasticity and toughness. It is not prone to brittle fracture under load, and can still maintain good toughness even at low temperatures, reducing the risk of fracture in harsh environments to ensure the good strength and toughness of the buckle 1.

[0031] The buckle 1 includes a first clip 11 and a second clip 12 . The first clip 11 and the second clip 12 each have an integrally formed clamping portion 2 and a fixing portion 3 .

[0032] The fixing portion 3 is a flat plate with a mounting hole 31 provided thereon. Bolts can pass through the mounting hole 31 to tightly and securely connect the fixing portion 3 of the first clip 11 and the fixing portion 3 of the second clip 12 .

[0033] The clamping portion 2 is semicircular in shape. The clamping portion 2 of the first clamping piece 11 and the clamping portion 2 of the second clamping piece 12 are sandwiched relative to each other to form a circular clamping space 13. This clamping space 13 can be used to clamp objects such as rods or tubes. In other embodiments, the clamping portion 2 can also be configured in other shapes, such as, but not limited to, polygonal or elliptical, depending on the shape of the object being clamped.

[0034] A coupling portion 21 is provided at one end of the clamping portion 2 away from the fixing portion 3 , and the coupling portion 21 of the first clamping piece 11 and the coupling portion 21 of the clamping portion 2 of the second clamping piece 12 are coupled and fixed to each other.

[0035] exist Figure 1 In the embodiment, the coupling portion 21 is a plane, and when the fixing portion 3 is fixedly connected, they are tightly coupled to each other. Furthermore, the coupling portion 21 of the clamping portion 2 can be provided with a magnet, and the two relatively clamping portions 2 can be more firmly coupled and fixed by the magnet.

[0036] exist Figure 2 In the embodiment, the coupling portion 21 of the first clip 11 is a snap-fit ​​member 23, which includes an extension section 24 and a snap-fit ​​section 25 connected in sequence. The extension section 24 extends from one end of the clamping portion 2 away from the fixing portion 3, and the snap-fit ​​section 25 extends from the end of the extension section 24 in the opposite direction of the extension section 24.

[0037] The coupling portion 21 of the second clip 12 is a clamping hole 22, and the diameter of the clamping hole 22 is larger than the clamping member 23. Figure 2As shown, the extension section 24 of the first clip 11 passes through the engaging hole 22, and the engaging section 25 folds around the engaging hole 22 and is folded in the opposite direction. The connection between the extension section 24 and the engaging section 25 is engaged with the engaging hole 22, thereby engaging the engaging member 23 of the first clip 11 with the engaging hole 22 of the second clip 12. Optionally, the engaging member 23 and the engaging hole 22 can be interference fit, so that the coupling portion 21 of the first clip 11 and the second clip 12 are more firmly connected.

[0038] It should be noted that the size of the clamping space 13 can be adjusted by adjusting the length of the extension section 24 of the clamping member 23 and the position of the clamping section 25 to adapt to the size of the clamped object.

[0039] The positions of the extension section 24 and the clamping section 25 of the clamping member 23 can be pre-set according to the object to be clamped, or the clamping member 23 can be passed through the clamping hole 22 first and then folded back to be fixed.

[0040] Furthermore, if Figures 3 to 5 As shown, the connection assembly of the present invention may further include an elastic sheath 5, which is disposed around the periphery of the clamped object, such as the clamped object 6, and the buckle 1. The elastic sheath 5 is made of a high-toughness material, such as natural rubber. Natural rubber has good elasticity and toughness. Therefore, the elastic sheath 5 can buffer vibrations and effectively provide both cushioning and protection, that is, reducing wear between the clamped object and the buckle 1, thereby increasing the service life of the connection assembly.

[0041] Alternatively, as Figure 4 As shown, the elastic sheath 5 can be provided with an installation cutout 51, and the elastic sheath 5 can be opened from the installation cutout 51, so that the elastic sheath 5 can be conveniently installed on the periphery of the clamped object 6, and the shape of the elastic sheath 5 can be restored by elasticity, and the installation cutout 51 can be merged, so that the elastic sheath 5 can be installed tightly against the clamped object.

[0042] Furthermore, if Figure 3 As shown, both ends of the elastic sheath 5 extend outwards and are provided with a snap-fit ​​edge 52, which is combined with Figure 5 It can be seen that the buckle 1 is clamped between the clamping edges 52 at both ends, so that the clamping edges 52 define the position of the buckle 1.

[0043] Optionally, the connection assembly may further include a connection member 4, such as Figure 6 As shown, connecting holes 41 are provided at both ends of the connecting member 4, and the connecting holes 41 are used to connect the mounting holes 31 of the fixing part 3 of the buckle 1 located at both ends of the connecting member 4. The length of the connecting member 4 can be set according to the spacing between two adjacent clamped objects 6.

[0044] exist Figure 6In the embodiment, the connecting member 4 is rectangular, and the four corners of the rectangle are arcs, which can prevent friction with the buckle 1. In other embodiments, the connecting member 4 can also be of other shapes, such as but not limited to circular, elliptical, polygonal, wedge-shaped, etc., as long as it can be fixedly connected to the buckle 1.

[0045] Figure 7 It is a three-dimensional schematic diagram of the connecting assembly of the present invention installed on the clamped object.

[0046] exist Figure 7 In the embodiment of the present invention, the clamped object is a guardrail 6. The following takes the guardrail as an example to illustrate the connection assembly of the present invention. It should be noted that the clamped object is a rod or a tube or other object that needs to be connected to each other.

[0047] Combine Figures 1 to 6 It can be seen that the elastic sheath 5 of the connecting assembly is sleeved on the periphery of the guardrail 6, and the clamping portion 2 of the first clip 11 of the buckle 1 and the clamping portion 2 of the second clip 12 are clamped with each other on the periphery of the elastic sheath 5, that is, the elastic sheath 5 together with the guardrail 6 are clamped in the clamping space 13.

[0048] The fixing portion 3 of the first clip 11 and the fixing portion 3 of the second clip 12 are clamped on both sides of the connecting member 4, and the mounting hole 31 of the first clip 11 and the mounting hole of the second clip 12 both correspond to the connecting through hole 41 at one end of the connecting member 4 and are fixed by bolts, so that the clamping portion 2 of the first clip 11 and the clamping portion 2 of the second clip 12 are clamped and fixed to the guardrail 6.

[0049] The buckle 1 connection mode of the other end of the connector 4 is the same as the buckle 1 connection mode of one end thereof, which will not be described in detail herein. In this way, two adjacent guardrails 6 are firmly connected together through the connecting assembly.

[0050] In an optional embodiment, the fixing portions 3 of the buckles 1 that respectively clamp adjacent guardrails 6 may also be fixedly connected to each other, and the connecting member 4 may be flexibly set according to the distance between adjacent guardrails 6 .

[0051] The modular design of the buckle 1 of the connection assembly of the present invention facilitates installation and removal of the connection assembly, and the buckle 1 can flexibly adjust the installation position and angle according to the actual installation situation to adapt to guardrails 6 of different shapes and specifications. During installation, the buckle 1 can flexibly adjust the installation position and angle according to the actual situation, while ensuring good safety and stability, and greatly simplifying the installation and removal operation process.

[0052] Moreover, the elastic sheath 5 of the connecting assembly can also increase the peripheral thickness of the guardrail 6 and change the shape of the clamped position of the guardrail 6 to adapt to the shape of the clamping space 13 of the buckle 1, so that the buckle 1 can clamp different shaped guardrails 6.

[0053] The connecting assembly has a simple and efficient locking structure, and can conveniently and effectively connect adjacent clamped objects.

[0054] The technical scope of the utility model is not limited to the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical concept of the utility model, and these modifications and changes should be within the scope of the utility model.
