Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, specifically to a guardrail fixing and steering accessory. Background Technology

[0002] Guardrails are mainly used in residential areas, highways, commercial areas, public places and other places to protect personal safety and equipment facilities. They can also be used to keep pets. Guardrails are generally made of interconnected wire mesh. In order to improve the installation efficiency and flexibility of guardrails.

[0003] In the existing technology, some guardrail connection devices adopt an adjustable angle structure. However, after the angle is adjusted, pins are often inserted into preset holes or a snap-on structure is used for fixing. This fixing method depends on a limited number of preset holes or snap-on positions. The adjustment process is cumbersome, requiring multiple insertions and removals of pins or adjustment of snap-ons, and it is difficult to achieve precise angle fine-tuning.

[0004] However, due to the limitations of the preset hole positions and buckle positions, when faced with complex and varied installation scenarios, such as irregular bends and undulating terrain, construction workers find it difficult to find a completely suitable fixing position, resulting in the inability to accurately adjust the guardrail connection angle and easy angle deviation. At the same time, the fixing stability of the pin and buckle structure is poor. During long-term use, it is easy to loosen or fall off due to external forces such as vehicle collisions and vibrations, causing the adjusted guardrail angle to shift.

[0005] In light of this, we have introduced a guardrail fixing steering accessory. Utility Model Content

[0006] The purpose of this utility model is to provide a guardrail fixing and steering accessory to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a guardrail fixing steering accessory, comprising: a steering joint A, an arc-shaped mounting base and a plug tube A;

[0008] The top of the steering joint A is provided with a steering joint B, and the top of the steering joint B is provided with a stop bar.

[0009] The arc-shaped mounting base is disposed on the top of the stop lever, and a steering joint C is movably connected to the top of the arc-shaped mounting base. A steering joint D is connected to the top of the steering joint C.

[0010] The insertion tube A is disposed on the surface of steering joint A, the surface of steering joint B is connected to insertion tube B, and the surfaces of steering joint C and steering joint D are respectively connected to insertion tube C;

[0011] An assembly structure is provided between the steering joint D and the arc-shaped mounting base. The arc-shaped mounting base and the steering joint D are assembled and fixed by the use of the screw and nut of the assembly structure.

[0012] Preferably, the assembly structure includes an external threaded portion connected to the surface of the screw, the external threaded portion and the screw being integrally formed, the screw being fixedly connected to the surface of the steering joint D, the nut being connected inside the arc-shaped mounting base, the nut having an internal threaded portion connected inside, the internal threaded portion and the nut being integrally formed, and the external threaded portion on the surface of the screw passing through the steering joint C and engaging with the internal threaded portion.

[0013] Preferably, the surface of the steering joint D is connected to an annular serrated protrusion, which is integrally formed with the steering joint D. The bottom of the steering joint C is connected to an annular serrated groove for engaging with the annular serrated protrusion, which is integrally formed with the steering joint C.

[0014] Preferably, the steering joint C has a hollow groove inside, and the hollow groove and the steering joint C are integrally formed. Reinforcing plates are connected at equal intervals inside the hollow groove, and the reinforcing plates are fixedly connected to the hollow groove or integrally formed.

[0015] Preferably, the top of the steering joint B has a slot for inserting a stop lever, the slot being used to fix the stop lever.

[0016] Preferably, a positioning ring is connected to the top of the steering joint A, and the positioning ring is inserted into the interior of the steering joint B. The positioning ring can be assembled by inserting into the interior of the steering joint B.

[0017] Preferably, the number of the annular serrated protrusions is two sets.

[0018] Preferably, the sides of the connectors A, B, and C are provided with mounting grooves, which facilitate the insertion of other components and form a shield. At the same time, the surfaces of connectors A, B, and C are each provided with arc-shaped portions for fingers to enter, making it convenient for operators to insert their fingers to insert or remove components. The tops of connectors A, B, and C are provided with bolt holes for bolts to pass through, allowing bolts to enter the interior of other components and fix them in place.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) The arc-shaped mounting base, steering joint C, and steering joint D are assembled and fixed by screwing the screw and nut. The operation method of rotating the arc-shaped mounting base to drive the nut to rotate is not only simple and convenient, but also allows the construction personnel to flexibly adjust the relative angle of steering joint C and steering joint D during the installation process. Whether it is a road bend, an intersection, or a complex and varied terrain, the guardrail can adjust the connection angle according to the actual needs to achieve seamless connection and perfect fit. The nut rotates on the surface of the screw to further fix the adjusted direction of steering joint C and steering joint D, making it more convenient to use.

[0021] (2) The ring-shaped sawtooth protrusions on the surface of the steering joint D and the groove at the bottom of the steering joint C interlock to form a unique angle locking mechanism. When adjusting the angle, a certain interlocking resistance must be overcome to ensure that the angle adjustment is controllable. When the appropriate angle is adjusted, it can be tightly engaged to provide strong anti-torsion force and prevent the guardrail angle from shifting due to external forces such as vehicle collision and vibration. This ensures that the guardrail maintains the predetermined protection angle during long-term use, continuously exerts stable protection performance, and reduces the workload of later maintenance and adjustment.

[0022] (3) The mounting grooves on the sides of the plug-in pipes A, B, and C and the bolt holes on the surface provide a wealth of possibilities for connecting guardrail components. The mounting grooves can be used to install various fasteners such as guardrail poles, and the bolt holes can be used to firmly fix the fasteners with bolts. Construction personnel can flexibly choose the connection method and combination form according to different guardrail types and installation requirements. Whether it is the splicing of guardrails on straight road sections or the connection of guardrail branches and turns in complex areas, it can be easily achieved. This effectively enhances the adaptability of the accessory to different guardrail installation projects, improves the convenience and diversity of guardrail installation, and reduces installation costs and time costs.

[0023] (4) By cooperating with the positioning ring on the top of the steering joint A and the steering joint B, a fast and accurate initial positioning is achieved, which greatly reduces the time cost and operational difficulty of component alignment during the installation process, and ensures that the relative positions of the steering joint A and the steering joint B are accurate, laying a solid foundation for subsequent assembly.

[0029] Please see Figure 1-3 This utility model provides a technical solution: a guardrail fixing steering accessory, including: a steering joint A1, a steering joint B3 is provided on the top of the steering joint A1, and a stop bar 5 is provided on the top of the steering joint B3, the stop bar 5 can be inserted and removed into the steering joint B3;

[0030] An arc-shaped mounting base 6 is provided on the top of the stop lever 5. The arc-shaped mounting base 6 can be inserted and removed into the interior of the arc-shaped mounting base 6. A steering joint C7 is movably connected to the top of the arc-shaped mounting base 6, and a steering joint D8 is connected to the top of the steering joint C7.

[0031] Connector A2 is disposed on the surface of steering joint A1 and is integrally formed with steering joint A1. Connector B4 is connected to the surface of steering joint B3 and is integrally formed with steering joint B3. Connector C17 is connected to the surfaces of steering joint C7 and steering joint D8 respectively and is integrally formed with steering joint C7 and steering joint D8.

[0032] An assembly structure is provided between the steering joint D8 and the arc-shaped mounting base 6. The arc-shaped mounting base 6 and the steering joint D8 are assembled and fixed by the cooperation of the screw 10 and nut 15 of the assembly structure.

[0033] The assembly structure includes an external threaded portion 11 connected to the surface of the screw 10. The external threaded portion 11 and the screw 10 are integrally formed. The screw 10 is fixedly connected to the surface of the steering joint D8. The nut 15 is connected inside the arc-shaped mounting base 6. The nut 15 has an internal threaded portion 16 connected inside. The internal threaded portion 16 and the nut 15 are integrally formed. The external threaded portion 11 on the surface of the screw 10 passes through the steering joint C7 and matches and screws into the internal threaded portion 16.

[0034] The surface of the steering joint D8 is connected to an annular serrated protrusion 9, which is integrally formed with the steering joint D8. The bottom of the steering joint C7 is connected to an annular serrated groove 12 for engaging with the annular serrated protrusion 9, which is integrally formed with the steering joint C7.

[0035] The steering joint C7 has a slot 13 inside, and the slot 13 and the steering joint C7 are integrally formed. Reinforcing plates 14 are connected at equal intervals inside the slot 13. The reinforcing plates 14 and the slot 13 are either fixedly connected or integrally formed.

[0036] The top of the steering joint B3 is provided with a slot 19 for inserting the stop lever 5, and the slot 19 is used to fix the stop lever 5.

[0037] The top of the steering joint A1 is connected to a positioning ring 18, and the positioning ring 18 is inserted into the interior of the steering joint B3. The positioning ring 18 can be assembled by inserting into the interior of the steering joint B3.

[0038] The number of the annular serrated protrusions 9 is two sets.

[0039] The sides of the connectors A2, B4, and C17 are provided with mounting grooves 20. The interior of the mounting grooves 20 facilitates the insertion of other components and forms a shield. At the same time, the surfaces of the connectors A2, B4, and C17 are respectively provided with arc-shaped parts for the insertion of fingers, making it convenient for operators to insert and remove components. The tops of the connectors A2, B4, and C17 are provided with bolt holes 21 for bolts to pass through. Bolts pass through bolt holes 21 to enter the interior of other components and fix the components.

[0040] Specifically, during use, when installing the guardrail, the steering joint A1 serves as the basic component. The positioning ring 18 at the top of the steering joint A1 is inserted into the steering joint B3 to achieve the initial positioning of the steering joint A1 and the steering joint B3, ensuring that their relative positions are accurate. (Subsequently, it can be further reinforced by other connection methods, such as adding glue at the joint or using additional connectors).

[0041] The slot 19 at the top of the steering joint B3 is used to insert the stop lever 5. After the stop lever 5 is inserted into the slot 19, a stable support structure is formed, which limits the excessive movement of the steering joint B3 in the vertical direction and enhances the overall structure's resistance to impact in the horizontal direction to a certain extent.

[0042] The arc-shaped mounting base 6 is located on the top of the stop lever 5, providing a base for the movable connection of the steering joint C7. The screw 10 on the surface of the steering joint D8 passes through the steering joint C7 and engages with the nut 15 inside the arc-shaped mounting base 6 through the matching of the external thread 11 and the internal thread 16, thereby assembling and fixing the steering joint D8 and the arc-shaped mounting base 6. During the assembly process, by rotating the arc-shaped mounting base 6, the nut 15 is driven to rotate, which can tightly connect the steering joint D8, the steering joint C7 and the arc-shaped mounting base 6 together (at the same time, the relative angle between the steering joint C7 and the steering joint D8 can be adjusted according to actual needs).

[0043] The annular serrated protrusion 9 on the surface of steering joint D8 and the annular serrated groove 12 at the bottom of steering joint C7 engage with each other. When the angle needs to be adjusted, a certain external force is required to overcome the resistance of engagement. After the angle is adjusted to a suitable angle, the engagement structure of the two (i.e., the annular serrated protrusion 9 and the annular serrated groove 12) can prevent relative rotation between steering joint C7 and steering joint D8, ensuring that the angle is fixed and that the guardrail can remain stable when connected at different angles.

[0044] The hollow groove 13 inside the steering joint C7 reduces its own weight and material cost. At the same time, the equally spaced reinforcing plates 14 inside the hollow groove 13 ensure the structural strength of the steering joint C7, making it less prone to deformation when subjected to external forces. It can stably transmit and disperse forces, ensuring the stability of the overall structure of the guardrail.

[0045] Mounting slots 20 are respectively opened on the sides of the insertion pipe A2 on the surface of steering joint A1, the insertion pipe B4 on the surface of steering joint B3, and the insertion pipe C17 on the surfaces of steering joint C7 and steering joint D8. The mounting slots 20 can be used to install some matching fasteners (guardrails, etc.), and the bolt holes 21 on the surfaces of insertion pipes A2, B4, and C17 can be used to pass bolts to fix the fasteners (guardrails, etc.), enhancing the overall stability and aesthetics of the connection, forming a variety of combination forms to meet different installation environments and design requirements.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
