Description

Technical Field

[0001] This utility model belongs to the field of guardrail technology and relates to a pipe connector for guardrails. Background Technology

[0002] Guardrails are widely used in roads, bridges, construction sites, and public places, and are an indispensable safety facility in modern society. Most guardrails are installed using a multi-component welding method, resulting in low installation efficiency. Alternatively, they are assembled guardrails, where the vertical fixed bars and horizontal connecting bars are fixedly connected by fixed connectors. These connectors are non-movable, and their fixed connection angle and position cannot be adjusted. This means that the connection angle and positioning between the vertical fixed bars and horizontal connecting bars are determined during installation and cannot be adjusted after completion. This makes the guardrails unable to flexibly adapt to complex terrains such as slopes with varying gradients and uneven ground. In special terrain or space-constrained situations, the fixed angle design increases installation difficulty and cost, as well as maintenance costs and time. Utility Model Content

[0003] The purpose of this utility model is to address the above-mentioned problems by providing a pipe fitting connector for a guardrail.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A pipe fitting for a guardrail includes a first connector and a second connector. The first connector has a sliding structure that can be inserted into a groove in a first guardrail and move radially along its axial direction. The second connector has a plug-in fitting that can be inserted into one end of a second guardrail. The first connector and the second connector are rotatably connected by a movable connecting mechanism, and the movable connecting mechanism defines at least one axis of rotation.

[0006] The first and second connecting bodies are rotatably connected by a movable connecting mechanism. This mechanism allows them to rotate relative to each other around at least one axis of rotation, enabling angle adjustment between the first and second railings. The first connecting body can move freely along the axial direction of the groove in the first railing via a sliding structure, facilitating adjustment of the positioning position of the second railing. Simultaneously, the first connecting body is radially limited within the groove to prevent radial displacement and disengagement. The plug-in mating part facilitates the insertion of the second connecting body into the end of the second railing, enabling rapid fixing of the second connecting body to the second railing. This effectively solves the problem of traditional railing connectors being unable to adjust the connection angle and positioning position, improving installation flexibility and adaptability. Furthermore, through the coordinated design of sliding and rotation, the railing is suitable for complex terrain or railing scenarios requiring dynamic adjustment.

[0007] In the aforementioned guardrail pipe connector, the sliding structure includes first guide flanges disposed on both sides of the first connector.

[0008] The first guide flange, in conjunction with the groove of the first railing, provides stable sliding guidance, preventing the first connecting body from tilting or disengaging from the groove during movement.

[0009] In the aforementioned guardrail pipe connector, a second guide flange is provided between the first connector and the second connector, and a guide groove is formed between the first guide flange and the second guide flange on the same side of the first connector.

[0010] The guide groove formed between the first guide protrusion and the second guide protrusion slides in conjunction with the guide protrusion of the slide groove to further limit the sliding direction of the first connector, thereby enhancing the stability of the first connector during sliding, preventing the first connector from shaking during movement, and providing radial limiting for the first connector.

[0011] In the aforementioned guardrail pipe connector, the plug-in mating part includes locking protrusions on both sides of the second connector, and a swinging gap is provided between the locking protrusions and the first connector.

[0012] The locking protrusions on both sides of the second connector cooperate with the inner wall of the second railing to provide positioning and fixation, enabling a firm connection. The swing gap between the locking protrusions and the first connector provides an angle adjustment margin to adapt to different installation requirements.

[0013] In the aforementioned guardrail pipe connector, the clamping protrusion is provided on the side along its swing direction, and an axially extending first inner step is provided on each of the two axial edges on the outer side of the clamping protrusion.

[0014] And / or, a second step is formed between the second connector and the upper and lower surfaces of the locking protrusion.

[0015] The first inner step is located on the axial edge outside the clamping protrusion, which can increase the contact area with the inner wall of the second railing and improve the pull-out resistance; the second step cooperates with the inner wall of the second railing to increase the contact area and improve the pull-out resistance.

[0016] In the aforementioned guardrail pipe connector, a hollow groove is provided between the outer end of the second connector and the clamping protrusion.

[0017] The hollowed-out groove can reduce the overall weight of the connector, reduce material costs, and provide elastic deformation space for the clamping protrusion, enhancing the buffering performance during insertion and removal.

[0018] In the aforementioned guardrail pipe connector, the movable connection mechanism includes a hinge assembly disposed between the first connector and the second connector.

[0019] The first and second connecting bodies are rotatably connected by a hinge assembly, which provides a stable axis of rotation, ensuring smooth and unbiased rotation, simplifying the rotatable connection structure, and facilitating assembly and maintenance.

[0020] In the aforementioned guardrail pipe connector, one end of the second connector is embedded in the hinged movable groove of the first connector and is hinged to the second connector via a hinge assembly.

[0021] The hinged movable groove is used to accommodate one end of the second connector. The hinged movable groove can limit the swing range of the second connector and prevent excessive rotation.

[0022] In the aforementioned guardrail pipe connector, the hinge assembly includes a hinge shaft passing through the first connector and the second connector.

[0023] One end of the second connector is embedded in the hinged movable groove of the first connector and is hinged to the second connector via a hinge shaft. The hinge shaft, as the core rotating component, bears the load transmitted by the railing and ensures structural stability.

[0024] In the aforementioned guardrail pipe connector, the first connector has inclined surfaces at both ends, and the inclined surfaces cause the length of the first connector to gradually decrease from the end close to the second connector to the end far from the second connector.

[0025] The beveled surfaces at both ends of the first connector facilitate insertion into the slide groove, reducing installation resistance and enabling it to adapt to slide grooves of different sizes, thus improving versatility.

[0026] Compared with existing technologies, the advantages of this utility model are as follows: 1. It effectively solves the problem that traditional guardrail connectors cannot adjust the connection angle and positioning, improving installation flexibility and adaptability. Through the coordinated design of sliding and rotation, it makes the guardrail suitable for complex terrain or scenarios requiring dynamic adjustment. 2. The first and second connectors are stably positioned and easy to assemble. 3. The rotational structure between the first and second connectors is simple, ensuring smooth rotation without sway, facilitating assembly and maintenance. Attached Figure Description

Detailed Implementation

[0034] like Figures 1-6 As shown, a pipe connector for a guardrail includes a first connector 1 and a second connector 2. The first connector 1 is provided with a sliding structure 5 that can be inserted into a groove 4 of a first railing 3 and move radially along its axial direction. The second connector 2 is provided with a plug-in mating part 7 that can be inserted into one end of a second railing 6. The first connector 1 and the second connector 2 are rotatably connected by a movable connecting mechanism, and the movable connecting mechanism defines at least one axis of rotation.

[0035] In this utility model, the first connecting body 1 can be inserted into the groove 4 of the first railing 3 through the sliding structure 5, and can move axially along the groove 4 but is radially limited. The second connecting body 2 can be inserted into one end of the second railing 6 through the insertion fitting part 7. The first connecting body 1 and the second connecting body 2 can be rotatably connected through the movable connecting mechanism, and the first railing 3 and the second railing 6 can be rotatably connected through the rotatable connection between the first connecting body 1 and the second connecting body 2.

[0036] The first connecting body 1 and the second connecting body 2 are used to connect the first railing 3 and the second railing 6, respectively. The first connecting body 1 and the second connecting body 2 are rotatably connected by a movable connecting mechanism. The movable connecting mechanism allows the two to rotate relative to each other around at least one rotation axis, which can realize the angle adjustment between the first railing 3 and the second railing 6. The first connecting body 1 can move freely along the axial direction of the slide groove 4 in the first railing 3 through the sliding structure 5, so as to adjust the positioning position of the second railing 6. At the same time, the first connecting body 1 is radially limited in the slide groove 4 to prevent the first connecting body 1 from radially offset and falling out. The plug-in mating part 7 facilitates the insertion of the second connecting body 2 into the end of the second railing 6, so as to realize the quick fixation of the second connecting body 2 and the second railing 6. This effectively solves the problem that traditional guardrail connectors cannot adjust the connection angle and positioning position, improves the installation flexibility and adaptability, and through the coordinated design of sliding and rotation, makes the guardrail suitable for complex terrain or guardrail scenarios that require dynamic adjustment.

[0037] The first connector 1 and the second connector 2 are made of wood-plastic composite material, as are the first railing 3 and the second railing 6, which have the advantages of strong anti-aging ability and high physical strength.

[0038] Specifically, combining Figure 3 and Figure 5 As shown, the sliding structure 5 includes a first guide flange 9 disposed on both sides of the first connecting body 1, a second guide flange 10 disposed between the first connecting body 1 and the second connecting body 2, and a guide groove 11 formed between the first guide flange 9 and the second guide flange 10 on the same side of the first connecting body 1.

[0039] The first guide flange 9 is located on both sides of the first connecting body 1 and is raised. The first guide flange 9 cooperates with the slide groove 4 of the first railing 3 to provide stable sliding guidance and prevent the first connecting body 1 from tilting or falling out of the slide groove 4 during movement. The second guide flange 10 is set on the same side as the first guide flange 9. The guide groove 11 formed between the first guide flange 9 and the second guide flange 10 slides with the guide protrusion of the slide groove 4 to further limit the sliding direction of the first connecting body 1. This can enhance the stability of the first connecting body 1 when sliding, prevent the first connecting body from shaking during movement, and play a radial limiting role for the first connecting body 1.

[0040] Preferably, combined with Figure 3 and Figure 5 As shown, both the first guide flange 9 and the second guide flange 10 are provided with arc-shaped chamfers.

[0041] The rounded chamfers on the first guide flange 9 and the second guide flange 10 reduce sliding friction resistance and extend the service life of the groove 4 and the guide flange.

[0042] Specifically, combining Figure 3 and Figure 6 As shown, the insertion and mating part 7 includes locking protrusions 12 disposed on both sides of the second connector 2, and a swinging gap 13 is provided between the locking protrusions 12 and the first connector 1.

[0043] The locking protrusions 12 on both sides of the second connector 2 cooperate with the inner wall of the second railing 6 to play a positioning and fixing role, which can achieve a firm insertion. The swinging gap 13 between the locking protrusions 12 and the first connector 1 can provide an angle adjustment margin to adapt to different installation requirements.

[0044] Preferably, combined with Figure 3 and Figure 6As shown, the insertion and mating part 7 includes locking protrusions 12 disposed on both sides of the second connecting body 2, and a swinging gap 13 is provided between the locking protrusions 12 and the first connecting body 1. The locking protrusions 12 are disposed on the side along their swinging direction, and axially extending first inner steps 14 are respectively provided on the two axial edges on the outer side of the locking protrusions 12;

[0045] And / or, a second step 15 is formed between the upper and lower surfaces of the second connector 2 and the locking protrusion 12.

[0046] The first inner step 14 is located on the axial edge outside the clamping protrusion 12, which can increase the contact area with the inner wall of the second railing 6 and improve the pull-out resistance.

[0047] In this embodiment, a second step 15 is formed between the upper and lower surfaces of the second connector 2 and the clamping protrusion 12. The second step 15 cooperates with the inner wall of the second railing 6, which can increase the contact area to improve the pull-out resistance.

[0048] Specifically, combining Figure 3 As shown, a hollow groove 16 is provided between the outer end of the second connector 2 and the clamping protrusion 12.

[0049] The hollowed-out groove 16 can reduce the overall weight of the connector, reduce material costs, and provide elastic deformation space for the clamping protrusion 12, enhancing the buffering performance during insertion and removal.

[0050] Specifically, combining Figures 3-6 As shown, the movable connection mechanism includes a hinge assembly 17 disposed between the first connecting body 1 and the second connecting body 2. One end of the second connecting body 2 is embedded in the hinge movable groove 18 of the first connecting body 1 and is hinged to the second connecting body 2 through the hinge assembly 17. The hinge assembly 17 includes a hinge shaft passing through the first connecting body 1 and the second connecting body 2.

[0051] The first connecting body 1 and the second connecting body 2 are provided with hinge holes 21 that are adapted to the hinge shaft.

[0052] One end of the second connecting body 2 is embedded in the hinge slot 18 of the first connecting body 1 and is hinged to the second connecting body 2 via a hinge shaft. The hinge shaft, as the core rotating component, bears the load transmitted by the railing and ensures structural stability. The first connecting body 1 and the second connecting body 2 are rotatably connected by the hinge assembly 17, which can provide a stable axis of rotation, ensure smooth rotation without sway, simplify the rotating connection structure, and facilitate assembly and maintenance. The hinge slot 18 is used to accommodate one end of the second connecting body 2 and can limit the swing range of the second connecting body 2 to prevent excessive rotation.

[0053] Specifically, combining Figures 3-6As shown, the first connector 1 has inclined surfaces 20 at both ends, and the inclined surfaces 20 cause the length of the first connector 1 to gradually decrease from the end close to the second connector 2 to the end far away from the second connector 2.

[0054] The inclined surfaces 20 at both ends of the first connector 1 facilitate the insertion of the first connector 1 into the slide groove 4, reduce installation resistance, and can adapt to slide grooves of different sizes, thus improving versatility.

[0055] The working principle of this utility model is as follows: the first guide flange 9, the second guide flange 10 and the guide groove 11 on both sides of the first connecting body 1 cooperate with the slide groove 4 of the first railing 3. The first connecting body 1 can move freely in the slide groove 4 along the axial direction of the slide groove 4 to adjust the positioning position of the second railing 6. The locking protrusions 12 on both sides of the second connecting body 2 cooperate with the inner wall of the second railing 6 for insertion.
