Description

Technical Field

[0001] This utility model relates to the field of rigid pipe connection technology, specifically to a multi-angle lightweight support connector. Background Technology

[0002] In various applications of equipment support and fixation, support connectors are key components, and their performance plays a decisive role in the overall stability, adaptability and portability of the equipment. Among the many types of traditional support connectors, disc-type connectors have been widely used in specific fields due to their own characteristics.

[0003] With the advancement of technology and the diversification of application scenarios, disc-type connectors have gradually revealed many limitations. Integrated, multi-angle, and lightweight support connectors have emerged to meet new demands and challenges.

[0004] Disc-lock connectors once held an important position in construction and other fields. Their structural design is based on specific connection principles. For example, in scaffolding erection, they connect to the ends of horizontal and diagonal braces via discs on the uprights. This connection method has certain advantages over some earlier scaffolding connections, such as relatively convenient installation and improved construction efficiency to a certain extent. However, from the perspective of functional integration, disc-lock connectors are essentially a relatively fragmented modular structure. Taking complex construction scenarios as an example, when erecting scaffolding of different sizes and shapes, it is necessary to match various specifications of horizontal and vertical braces, as well as a large number of disc-lock connectors. The variety and quantity of components are numerous. This not only increases the difficulty of on-site management and makes it easy for components to be lost or misplaced, but also requires workers to assemble each component one by one during the assembly process. The operation steps are cumbersome and greatly affect the erection efficiency. Furthermore, it is difficult to ensure the accuracy of the connection when combining multiple components, which can easily lead to loose connections and affect the overall stability of the scaffolding.

[0005] In addition, the original design of disc-lock connectors is mainly to meet the basic vertical and horizontal erection needs common in building construction. They have almost no angle adjustment function. Taking the scaffolding erection scenario during the construction of building exterior walls as an example, when it is necessary to make fine adjustments to the scaffolding to adapt to the operation requirements of irregular building facades, disc-lock connectors are difficult to achieve flexible and varied angle adjustments.

[0006] Since disc-lock scaffolding is mainly used in construction and other scenarios with high load-bearing capacity requirements, heavy metal materials, such as ordinary steel or some low-alloy steel, are usually used to ensure sufficient strength and stability. Taking the construction of high-rise scaffolding in large-scale construction projects as an example, the extensive use of disc-lock scaffolding significantly increases the weight of the entire scaffolding system. This not only brings great difficulties to the transportation and installation of scaffolding, requiring the use of large machinery for handling and increasing construction costs, but also, in some construction sites with limited ground load-bearing capacity, an excessively heavy scaffolding system may damage the ground and affect construction safety.

[0007] In summary, the shortcomings of traditional disc-type connectors in terms of functional integration, angle adjustment, lightweighting, and spatial adaptability are becoming increasingly apparent, making it difficult to meet the diverse application needs of modern times. In contrast, integrated, multi-angle, and lightweight support connectors, with their innovative design concepts and superior performance, provide an effective way to solve these problems and have broad application prospects and huge market value. Summary of the Invention

[0008] To address the aforementioned issues, this utility model provides a multi-angle lightweight support connector. Through integrated casting, a three-dimensional structure is formed, with each part seamlessly connected. This enables force transmission and component connection from the base 1 to the upper support. It is suitable for connecting industrial machinery and equipment that require spatial layout and support stability, or for building construction scenarios, ensuring structural strength and durability.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a multi-angle lightweight support connector, characterized in that the support connector has an overall three-dimensional composite structure, comprising a base 1, a middle connecting arm 3, and an upper support sleeve 4.

[0010] The base 1 has a flat plate structure and serves as the installation reference surface. This flat plate structure is used as a positioning reference for fixed connection with other equipment or the ground.

[0011] The bottom of the middle connecting arm 3 is fixedly connected to the base 1, and it also includes a frame structure with hollow and bent features composed of two cylindrical components;

[0012] The upper support sleeve 4 adopts a combination of groove and semi-envelope structure to form a receiving cavity, which is used to adapt to and fix the target pipe to be supported. The cavity wall shape fits the shape of the target pipe to ensure connection stability.

[0013] Preferably, the base 1 is an approximately elliptical flat plate structure with uniform thickness and chamfered or rounded edges. The area in the middle connected to the bottom of the central connecting arm 3 is hollowed out, and the shape of the hollowed-out area is consistent with the outer shape of the base 1. Multiple circular bolt mounting holes 2 are distributed on the base 1, and the diameter of the bolt mounting holes 2 is consistent. They are rigidly connected to the external foundation structure through fitting fasteners.

[0014] Preferably, the middle connecting arm 3 includes a two-part structure, including a bottom connected to the base 1. The front end of the base is provided with a cylindrical member that obliquely penetrates the base 1. The first pipe sleeve 5, which serves as the supporting connector, is connected to the hollow area of ​​the base 1 internally and protrudes from the surface of the base 1 externally, forming an arc-shaped clamp 5-1. In addition, the first pipe sleeve 5 is horizontally cut from the upper edge of the arc-shaped clamp 5-1, with the front part occupying 2 / 3 of the inner diameter. The starting end of the cut area is located at the upper edge of the arc-shaped clamp 5-1 and extends upward along the axial direction of the first pipe sleeve 5.

[0015] Preferably, the middle connecting arm 3 further includes an axial extension section of the cut area on the first pipe sleeve 5, and a frame structure formed by the attachment 6; the attachment 6 is a platform with a transverse cross section that is approximately rectangular with a semi-circular front end, similar and parallel upper and lower bottom surfaces, and a smaller lower bottom area and a larger upper bottom area. The rear end of the platform is fixedly connected to the axial extension section of the first pipe sleeve 5, and a semi-circular hole consistent with the inner hole of the first pipe sleeve 5 is opened at the connection point, and the two are connected as one; in addition, another circular hole is opened at the front end of the platform as a second pipe sleeve 7. The central axes of the first pipe sleeve 5 and the second pipe sleeve 7 intersect each other and are in the same plane, which is used to accommodate the insertion and limiting of pipes or supports at a predetermined angle.

[0016] Preferably, the upper support sleeve 4 is an extension of the first pipe sleeve 5, with its outer side being a vertical end face, serving as a reinforcing section of the first pipe sleeve 5, and a vertical reinforcing rib 4-1 is provided on the outer edge of the lower cylinder wall.

[0017] Preferably, a rectangular support seat 8 is provided at the bottom rear end of the middle connecting arm 3, that is, at the part where the rear side of the first pipe sleeve 5 intersects with the base 1. A circular hole is provided on the wall of the first pipe sleeve 5 along the upper edge of the rectangular support seat 8, which is perpendicular to the axial direction of the first pipe sleeve 5 and extends upward to the lower side of the attachment 6 of the middle connecting arm 3. The circular hole and the extended part serve as the third pipe sleeve 9, which can effectively support the first pipe sleeve 5 and the second pipe sleeve 7 when facing the stepped mounting reference surface.

[0018] Preferably, the arc-shaped clamp 5-1 formed by the first pipe sleeve 5 and the base 1 has a locking hole 10 on its side, and the installation of locking screws can fix the pipe passing through the first pipe sleeve 5. Beneficial effects

[0019] ①The base 1 described in this application adopts an approximately elliptical flat plate structure with a hollow design in the middle. The hollow area is consistent with the outer shape of the base 1. Combined with the frame structure and gradually changing wall thickness design of the middle connecting arm 3, the material usage is reduced while the structural rigidity is ensured by the reinforcement of the arc-shaped clamp 5-1, the vertical reinforcing rib 4-1 and the rectangular support seat 8, thus meeting the dual requirements of lightweight and load-bearing capacity.

[0020] ②The central axes of the first pipe sleeve 5 and the second pipe sleeve 7 of the middle connecting arm 3 described in this application intersect and are coplanar, which can adapt to pipe insertion and positioning at different angles; the grooved and semi-enclosed structure of the upper support sleeve 4 of the first pipe sleeve 5 can be compatible with target pipes of various diameters and directions, covering multi-angle support needs in multiple scenarios such as household equipment and industrial pipelines.

[0021] ③ The base 1 is rigidly connected to the external structure through the bolt mounting holes 2. The arc-shaped clamp 5-1 of the first pipe sleeve 5 cooperates with the side locking hole 10, combined with the rubber pad and elastic groove of the upper support sleeve 4, to achieve double fixation of the pipe, reduce the use of fasteners, and improve installation efficiency.

[0022] ④ In addition, this application has specially designed a third pipe sleeve 9 for inserting auxiliary support rods when targeting the stepped installation reference surface, which, together with the rectangular support base 8, enhances the overall stability; the chamfering / rounding treatment of the base 1 edge and the optimization of the platform structure enable it to be safely assembled in narrow spaces or complex environments, and the scope of application has been expanded from supporting a single device to the coordinated fixing of multiple pipeline systems.

[0026] The technical solution of this application will be further described with reference to the accompanying drawings.

[0027] refer to Figure 1and 2 The multi-angle lightweight support connector provided by this utility model is formed by an integrated casting process, forming a three-dimensional composite structure as shown in Figure 1-2. It includes a base 1, a middle connecting arm 3 and an upper support sleeve 4. Each component achieves lightweighting through gradual wall thickness and hollow design, while strengthening the structure to ensure rigidity.

[0028] I. Core Components

[0029] 1. Base 1:

[0030] The base 1 is an approximately elliptical flat plate with chamfered / rounded edges. The connection between the base 1 and the central connecting arm 3 is hollowed out, and the outline of the hollowed-out area is consistent with the outer perimeter of the base, which reduces weight while retaining the rigid positioning function of the bolt mounting holes 2.

[0031] Installation: The device is rigidly connected to an external foundation such as an equipment base or wall through evenly distributed circular bolt mounting holes 2, and is fitted with standard fasteners to form a stable reference surface.

[0032] 2. The middle connecting arm 3 includes:

[0033] The first pipe fitting sleeve 5 is a cylindrical structure that penetrates the base 1 at an angle, forming an arc-shaped clamp 5-1 on the outside. The upper 2 / 3 area is horizontally cut to form a groove-shaped opening, which is compatible with the insertion of pipe fittings of different diameters. The clamp has a locking hole 10 on its side, which is used to fix the pipe fitting with screws to prevent loosening.

[0034] The second pipe fitting sleeve 7: The angle between the coplanar axis of the second pipe fitting sleeve 5 and the first pipe fitting sleeve 5 can be designed according to the requirements. It is fixed by the platform structure of the attachment 6. The rear end of the platform is connected to the cut extension section of the first pipe fitting sleeve 5. The front end round hole forms the second sleeve, realizing the multi-angle positioning of the two pipe fittings.

[0035] The third pipe sleeve 9: At the junction of the first pipe sleeve 5 and the base 1, a circular hole with a vertical axis is opened through the rectangular support seat 8, through which an auxiliary support rod can be inserted to adapt to the stepped mounting surface and enhance the stability of complex scenes.

[0036] 3. Upper support sleeve 4:

[0037] The extension of the first pipe fitting sleeve 5 has a vertical end face on the outside and vertical reinforcing ribs 4-1 on the lower cylinder wall. The inside is a semi-enclosed cavity that fits the shape of the pipe fitting, such as a circle or polygon. It can be equipped with a rubber pad to achieve a combination of flexible clamping and rigid positioning. As the top support point of the pipe fitting, it works with the middle sleeve to form a double fixation of "bottom support and top embrace", reducing reliance on a single fastener and improving installation efficiency.

[0038] II. Lightweight and Strength Optimization Design

[0039] The middle part of the base 1 and the middle connecting arm 3 frame are both hollowed out, and the material is concentrated in the stress area such as the area around the bolt hole and the sleeve connection, which reduces the weight by 30%-40%. At the same time, the rigidity is maintained by the arc-shaped clamp 5-1 and the reinforcing rib 4-1.

[0040] The wall thickness at the connection between the sleeve and the base is increased and gradually thins towards the edge to avoid stress concentration; the structure of Annex 6 is thicker at the top and thinner at the bottom, taking into account both support strength and lightweight.

[0041] III. Multi-angle design

[0042] The double-sleeve cross layout, with the first sleeve 5 and the second sleeve 7 having intersecting and coplanar axes, allows the pipes to be inserted at different angles and fixed by locking holes 10, adapting to scenarios such as equipment tilting and curved surface support.

[0043] IV. Step surface support

[0044] The third fitting sleeve 9, in conjunction with the rectangular support base 8, can be inserted with an auxiliary rod to abut against the step surface, forming a triangular support and preventing the connector from being suspended and subjected to force.

[0045] Installation Process Example

[0046] Base fixing: The base 1 is fixed to the mounting surface by bolts, and the positioning error of the bolt holes 2 is ≤0.5mm;

[0047] Pipe fitting pre-assembly: Insert the main pipe fitting into the first pipe fitting sleeve 5, adjust the angle, and tighten the screw; insert the branch pipe fitting into the second sleeve 7 and fix it as needed;

[0048] Top limiting: Insert the top of the pipe fitting into the upper support sleeve 4, and fix it by setting a pad to adapt to the pipe diameter;

[0049] If a stepped surface is encountered, an auxiliary rod is inserted into the third sleeve 9, and the support seat 8 abuts against the vertical surface to form a stable triangular structure.
