Description

Technical Field

[0001] This utility model belongs to the field of pipe connection technology, specifically, it relates to a multifunctional integrated pipe joint and its components. Background Technology

[0002] In home, personal studio, and other lightweight structure construction scenarios, the following problems are commonly encountered:

[0003] 1. Insufficient fastening reliability: Conventional pipe fittings have shallow thread hole depths, resulting in poor tightening effect and easy thread failure and loosening.

[0004] 2. Low aesthetic integration: The structural design of ordinary reinforced threads lacks visual optimization and is difficult to coordinate with the home environment or living scene.

[0005] 3. Difficulty in securing: While maintaining aesthetic consistency, it is difficult to increase the number of screw holes to improve the reliability of structural connections and installation flexibility, resulting in poor fastener stability.

[0006] 4. Lack of board / shelf fixing features: Existing pipe fittings lack systematic features that can be directly used for fixing diverse materials such as boards, shelves, and walls.

[0007] 5. Waste of resources: Metal pipes (such as galvanized pipes and stainless steel pipes) with excellent economic efficiency, reliability and sustainability are not fully utilized due to the lack of suitable fasteners.

[0008] 6. Inconvenient assembly: Users need easier-to-operate pipe cutting solutions on site, such as using air conditioning copper pipe rotary cutting tools to achieve sparkless cutting.

[0009] 7. Limited application scenarios: Traditional pipe fittings are mainly used in industrial guardrails, lacking visual and functional optimization suitable for homes or personal studios.

[0010] 8. Fixed dimensions: Commercially available storage racks, clothes racks and other furniture have fixed lengths, widths and heights, which cannot perfectly fit the space of the usage environment.

[0011] Existing pipe fittings mostly only allow for single-angle connections of pipes and lack integrated fixing structures with sheet metal. If it is necessary to assemble the frame and install side panels, top panels, and other components using pipe fittings, additional connectors are required, resulting in cumbersome assembly steps and insufficient structural stability. Furthermore, there is a lack of dedicated integrated fittings for metal pipes such as galvanized pipes, which limits the application of metal pipes in the field of lightweight frames. Utility Model Content

[0012] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multifunctional integrated pipe connector and its components.

[0013] To achieve the aforementioned objectives, the technical solution adopted by this utility model includes:

[0014] A fixed pipe joint is provided, which consists of at least two insertable pipe joints for connecting pipes in a plane; the outer side of the fixed pipe joint is provided with a plurality of enlarged and thickened protrusions, each of which is provided with at least one threaded hole for fastener connection, and the opening height of the insertable pipe joint is consistent with the height of the protrusion.

[0015] In this utility model, the structure of "fixed pipe joint consisting of at least two insertable pipe joints" enables stable connection of pipes in a plane, meets basic pipe splicing requirements, and provides basic connection units for subsequent expansion component structures.

[0016] The design of "multiple enlarged and thickened protruding structures with threaded holes on the outside of the fixed pipe joint" provides a deeper and more stable threaded connection foundation than conventional pipe joints, solving the problem of "shallow threaded hole depth and poor tightening effect" in existing technologies. On the other hand, the threaded holes can be directly used as connection points for fixing plates, shelves, and walls, making up for the deficiency of existing pipe joints "lacking plate / shelf fixing features". At the same time, it is compatible with the connection needs of metal pipes such as galvanized pipes and stainless steel pipes, solving the problem of "metal pipes not being fully utilized due to the lack of suitable fixing accessories".

[0017] It should be noted that the fixed pipe joint refers to the three outer wall surfaces formed along the two radial directions of the pipe connection plane (such as the XY plane) and the axial direction perpendicular to the plane (such as the Z axis direction), which can be used for pipe connection or external fitting fixation. The three outer wall surfaces are spatially distributed around the center of the pipe joint. The at least two insertable pipe joints are respectively set along the two radial directions of the pipe connection plane to realize the right-angle connection of the pipe in the plane.

[0018] The pipes include metal pipes (such as galvanized pipes and stainless steel pipes) and are adapted to the connection requirements of metal pipes.

[0019] The enlarged and thickened structure refers to the wall thickness of the protruding structure being no less than 1.2 times the wall thickness of the fixed pipe joint body, and the protrusion height of the protruding structure along the radial direction of the pipe joint being no less than the protrusion height of the same type of protruding structure in conventional pipe joints, so as to ensure the effective connection length of the threaded hole and the structural bearing strength.

[0020] Preferably, each of the protruding structures has 1 to 3 threaded holes, and the diameter of the threaded holes is adapted to the outer diameter of the fastener used for pipe connection.

[0021] In this utility model, "each protruding structure is provided with 1 to 3 threaded holes" can be selected according to the actual connection requirements to determine the number of fixing points: 1 threaded hole meets the basic fixing requirements, 2 to 3 threaded holes can provide multi-point fixing, enhance the connection reliability, and can also be used for the connection and fixing of external components, solving the problem of "difficulty in strengthening fixing" in the prior art.

[0022] The design of "matching the threaded hole diameter with the outer diameter of the fastener for pipe connection" ensures the compatibility of the fastener (such as screw) with the threaded hole, avoids loose connection, thread failure or installation jamming due to size mismatch, and improves connection stability and installation convenience.

[0023] Preferably, at least one protruding structure is provided in the same axial direction of the fixed pipe joint, and the height of the protruding structure is consistent among pipe joint fittings of the same size sequence.

[0024] In this utility model, the design of "at least one protruding structure on the same axis" can meet the requirements of higher strength or multi-point connection (such as fixing long plates), further improve the structural connection strength, and solve the problem of "insufficient fastening reliability" in the prior art.

[0025] The design of "consistent protrusion height of pipe fittings of the same size sequence" can avoid interference between different pipe fittings during modular assembly, and is suitable for modular structure construction such as cabinets and shelves in homes and personal studios; at the same time, the uniform height design can improve visual consistency, improve the problem of "low aesthetic integration" of existing technologies, and make pipe fittings more suitable for home or living scenarios.

[0026] It should be noted that the 'same axial direction' refers to the axial direction that is consistent with the axial direction of the insertable pipe fitting for pipe insertion (e.g., when the pipe is inserted along the X-axis, this axial direction is the X-axis direction; when the pipe is inserted along the Y-axis, this axial direction is the Y-axis direction), ensuring that the protruding structure is distributed along the pipe connection direction to meet the fixing requirements of long plates or multiple accessories.

[0027] A multifunctional integrated pipe fitting assembly includes at least four multifunctional integrated pipe fittings, two lower horizontal braces, two lower vertical braces, and four vertical braces. The two lower horizontal braces are respectively inserted into the same-side insertable pipe fittings of the corresponding multifunctional integrated pipe fittings. The 'corresponding position' refers to the four multifunctional integrated pipe fittings being arranged in a rectangular pattern, located at the four apex corners of the rectangle, so that every two multifunctional integrated pipe fittings form a single-sided component. The same-side insertable pipe fittings refer to the insertable pipe fittings at both ends of the same long side of the rectangle, facing that long side and used to insert into the lower horizontal braces. That is, the two lower horizontal braces respectively connect the pipe fittings at both ends of the two long sides of the rectangle, so that every two adjacent apex corner pipe fittings and one lower horizontal brace form a single-sided component.

[0028] The two lower longitudinal braces are respectively inserted into the corresponding insertable pipe connectors of the two single-sided pieces, so that the two single-sided pieces are spliced ​​together to form a planar piece; the bottom of the fixed pipe connector has a lower interface, and the four vertical braces are respectively inserted into the lower interfaces of the four multi-functional integrated pipe connectors. The 'corresponding insertable pipe connector' refers to the insertable pipe connector of the two single-sided pieces that is not connected to the lower horizontal brace and faces the short side of the rectangle, that is, the two lower longitudinal braces are respectively connected to the pipe connectors at both ends of the two short sides of the rectangle, so that the two single-sided pieces are spliced ​​together to form a rectangular planar piece.

[0029] In this utility model, the components are assembled by "the lower horizontal brace and the pipe joint are inserted to form a single-sided component, the lower longitudinal brace is connected to the single-sided component to form a planar component, and the vertical brace is inserted to provide vertical support". This method requires no complicated tools, simplifies on-site assembly operations, and solves the problem of "inconvenient assembly" in the prior art.

[0030] The resulting "frame structure with vertical support" can be adapted to scenarios such as home storage shelves and personal studio shelves, breaking through the traditional single application of pipe joints, which is mainly "industrial guardrails", expanding the application scenarios of pipe joints and solving the problem of "single application scenarios".

[0031] Preferably, it also includes a top plate, side plates, and a front plate; the top plate covers the top of the flat component, and the side plates and front plate are respectively attached to two adjacent sides of the flat component; when the plates are attached, the end face of the protruding structure is used as the positioning reference to ensure that the inner wall surface of the plate is in close contact with the end face of the protruding structure. At the same time, the position of the plate is adjusted by visual inspection or simple measuring tools to ensure that the mounting holes on the plate are coaxially aligned with the threaded holes on the protruding structure. Then, the connecting screws are screwed in to complete the fixation. The screws should be screwed in to a depth that fits the surface of the plate without loosening.

[0032] Both the top and side plates have mounting holes that match the threaded holes. Connecting screws are threaded into these mounting holes, with one end of each screw passing through the mounting hole and threaded into the corresponding threaded hole on the protruding structure. The term "fitting arrangement" refers to the close contact between the inner wall surface of the side and front plates and the upper surface of the protruding structure at the edge of the flat component or the outer wall surface of the fixed pipe joint, with the edge of the plate aligned with the edge of the pipe joint or protruding structure, ensuring that the mounting holes on the top and side plates are coaxially corresponding to the threaded holes on the protruding structures.

[0033] In this utility model, the design of "connecting screws passing through the mounting holes of the top plate and side plate and connecting with the threaded holes of the protruding structure" can achieve a stable fixation of the top plate, side plate, front plate and base frame, forming a complete closed or semi-closed structure (such as a storage cabinet or display rack), thus solving the defect of "lacking board / shelf fixing features" in the prior art.

[0034] The integrated connection between the panels and the frame enhances the structural integrity and practicality of the components, meeting the needs of families and personal studios for structures with panel protection or storage functions, and further expanding the functional scenarios of the components.

[0035] Preferably, it also includes multiple set screws; the side wall of the fixed pipe joint is provided with a screw hole that matches the set screw, and after the set screw is screwed into the screw hole, its end abuts against the outer wall of the corresponding lower horizontal or lower vertical brace inserted into the pipe joint.

[0036] In this utility model, the design of "the set screw being screwed into the screw hole and abutting against the lower horizontal / lower vertical brace" can limit and fix the inserted horizontal and vertical braces from the side wall of the pipe joint, preventing the horizontal and vertical braces from loosening or shifting when subjected to force or vibration, thus solving the problem of "poor tightening effect of conventional pipe joints and easy thread failure and loosening" in the prior art.

[0037] The addition of set screws can improve the overall tightness and reliability of the component connection, ensure the structural stability of the frame when bearing heavy objects (such as items placed on a storage shelf), and extend the service life of the component.

[0038] Preferably, the two lower longitudinal supports are respectively inserted into the interface at the middle position of the fixed pipe joint of the multifunctional integrated pipe joint, so that the protruding structure of the fixed pipe joint at the edge of the component is used for connecting external accessories.

[0039] In this utility model, the design of "connecting the lower longitudinal brace with the middle of the fixed pipe joint" provides a protruding structure on the edge of the component as an "external accessory connection interface", which can be adapted to the installation of external accessories such as casters, hooks, and additional shelves, thereby improving the functional expandability and installation flexibility of the component and solving the problems of "difficulty in strengthening fixation and single function" in the prior art.

[0040] Preferably, the height of the protruding structure of other pipe fittings of the same size sequence is consistent with the height of the protruding structure on the fixed pipe fitting. In this invention, by limiting the height of the protruding structure of other fittings of the same size sequence to be consistent with that of the fixed pipe fitting, physical obstruction or misalignment caused by height differences between different fittings (such as annular extension parts, caster mounting parts, shelf support parts, etc.) during assembly can be directly avoided, ensuring that each fitting can be smoothly assembled along the preset position.

[0041] Compared with the prior art, the advantages of this utility model include:

[0042] (1) The present invention provides a multifunctional integrated pipe joint with a protruding structure that significantly increases the effective length of the fastening thread, improves stress concentration, and reduces the risk of thread failure and pipe joint rupture. After the connection efficiency is improved, the pipe wall can be thinned under the same load, achieving lightweight and low cost.

[0043] (2) The multifunctional integrated pipe joint provided by this utility model has an increased surface area of ​​the protruding structure, which is beneficial for fixing plates and other components and greatly expands the application range; the protruding structure is used in conjunction with fine-tooth set screws to significantly improve the anti-loosening performance in vibration scenarios; the height of the protruding structure is consistent with the opening of the pipe joint and remains uniform in the same size series of accessories, increasing the possibility of diversified fixing.

[0044] (3) The present invention provides a multifunctional integrated pipe connector with one or more screw holes on the protruding structure, which can enhance the reliability of the pipe connector system connection; the upper surface of the protruding structure is conducive to the fixing of plates or other accessories, expanding the application scenarios; the support structure of the same size series has the same height, which is conducive to the free combination of various components.

[0045] (4) The present invention provides a multi-functional integrated pipe joint. The present invention integrates right-angle connection and plate fixing functions through fixed pipe joint, eliminating the need for additional connecting parts, realizing integrated assembly of pipe connection and plate fixing, and improving assembly efficiency; the enlarged and thickened protruding structure ensures the load-bearing strength of the threaded connection and adapts to the rigid connection requirements of metal pipes; the multi-directional interface and protruding structure distribution allows a single joint to adapt to different assembly angles and fixing requirements, significantly improving the adaptability and practicality of the product.

Unless otherwise specified, the dimensions, materials, and manufacturing processes of the various components in the multifunctional integrated pipe connector in this utility model embodiment can be selected according to specific circumstances, and no special limitations or explanations are made here.

[0059] Furthermore, to provide the public with a better understanding of this utility model, certain specific details are described in detail in the following description. However, those skilled in the art can fully understand this utility model even without these detailed descriptions.

[0060] Example 1

[0061] Please see Figure 1 This embodiment discloses a multifunctional integrated pipe connector, including a fixed pipe connector 5. The fixed pipe connector 5 includes two insertable pipe connectors 9 for in-plane connection. The outer side of the fixed pipe connector 5 is provided with multiple enlarged and thickened protruding structures 11, each protruding structure 11 having at least one threaded hole. In this embodiment, each protruding structure 11 has one threaded hole; in other embodiments, each protruding structure 11 has two or three threaded holes. Furthermore, any number of threaded holes meeting production requirements can be added according to specific usage needs to enhance the connection reliability of the pipe connector system.

[0062] In this embodiment, the protruding structure 11 is applied to the fixed pipe joint 5 with three sides. In other embodiments, the application of the protruding structure 11 includes, but is not limited to, single-head pipe joints, double-head pipe joints, triple-head pipe joints, and other pipe joints required for the construction scenario.

[0063] The 'three sides' of the fixed pipe joint 5 refer to the three mutually perpendicular outer wall surfaces formed along the central axis of the pipe joint, corresponding to two radial directions (such as the X-axis and Y-axis directions) and one axial direction (such as the Z-axis direction); at least two insertable pipe joints 9 are integrated inside, and the interfaces of the insertable pipe joints 9 are respectively opened on the outer wall surfaces in the two radial directions to realize the right-angle connection of the pipe in the plane. The outer wall surface in the axial direction is used to set the protruding structure 11 to adapt to the fixing of the plate.

[0064] It should be noted that the end face of the protruding structure 11 is provided with a threaded hole, the depth of which is adapted to the thickened size of the protruding structure 11 to ensure connection strength. When it is necessary to fix the side plate 2, top plate 8, and other plates, the plates and pipe fittings can be detachably fixed by passing connecting screws through the mounting holes and threaded holes on the plates; unused threaded holes can be sealed with plugs to prevent impurities from entering.

[0065] Example 2

[0066] Please see Figure 1 This embodiment discloses an assembly for a multifunctional integrated pipe connector, applied to a three-sided panel fixing scenario. The assembly includes two lower cross braces 6. This assembly uses four multifunctional integrated pipe connectors. During single-sided assembly, the four multifunctional integrated pipe connectors are first arranged in a rectangular pattern, using the axial center line of the pipe connectors as a reference to ensure the radial interfaces of adjacent pipe connectors are aligned. Then, the end of the lower cross brace 6 is smoothly inserted axially along the interface of the insertable pipe connector 9. The insertion depth is based on the limiting structure of the inner wall of the pipe connector to ensure a secure connection. Every two adjacent pipe connectors and one lower cross brace 6 form a single-sided assembly. The two lower cross braces 6 are respectively connected to the corresponding multi-functional integrated pipe joints, so that the two insertable pipe joints 9 on the same side of each pair of multi-functional integrated pipe joints are connected by the lower cross braces 6. The two multi-functional integrated pipe joints are connected by a lower cross brace 6 to form a single-sided piece. Two lower longitudinal braces 7 are provided between the two single-sided pieces. The two lower longitudinal braces 7 are respectively connected to the corresponding insertable pipe joints 9, so that the two single-sided pieces are connected by the lower longitudinal braces 7 to form a flat piece. The bottom of the fixed pipe joint 5 is provided with a lower interface. The lower interfaces of the four multi-functional integrated pipe joints are all connected to vertical braces 1.

[0067] It should be noted that not all pipe fittings in the components used in the multi-functional integrated pipe fitting are multi-functional integrated pipe fittings. Some are ordinary pipe fittings without the protruding structure 11. Whether to use a multi-functional integrated pipe fitting depends on whether accessories need to be added to the side of the component. When accessories need to be added to the side of the component, a multi-functional integrated pipe fitting with the protruding structure 11 should be used. When accessories do not need to be added to the side of the component, an ordinary pipe fitting without the protruding structure 11 should be used.

[0068] Furthermore, the top of the flat component is covered with a top plate 8, and the two adjacent sides of the flat component are respectively provided with side plates 2 and front plates 10. The top plate 8 and the two side plates 2 are internally threaded with multiple connecting screws 3, and the multiple connecting screws 3 are threadedly connected to the threaded holes at the corresponding positions.

[0069] It should be noted that, in order to ensure the stable connection between the multi-functional integrated pipe fitting and the two lower horizontal supports 6 and the two lower vertical supports 7, a set screw 4 is screwed into the fixed pipe fitting 5 and connected to the lower horizontal supports 6 and the lower vertical supports 7 at the corresponding positions, thereby stabilizing the structural connection stability of the planar component.

[0070] The protruding structure 11 can be used as a support structure for sheet metal or other components, and is suitable for modular structures such as cabinets, shelves, and space supports.

[0071] Example 3

[0072] Please see Figure 2 , Figure 3 and Figure 4 This embodiment discloses an assembly for use in a multifunctional integrated pipe connector, which is applied to a scenario where two symmetrical plates are fixed. Based on embodiment 2, the difference from embodiment 2 is that the protruding structure 11 is T-shaped. The two lower longitudinal supports 7 and the multifunctional integrated pipe connector are no longer connected to the side of the fixed pipe connector 5, but are instead connected to the two lower longitudinal supports 7 through the middle of the fixed pipe connector 5. This allows the fixed pipe connector 5 to reserve the protruding structure 11 at the edge of the entire assembly as an interface for connecting other accessories.

[0073] Furthermore, the fixed pipe joint 5 has multiple protruding structures 11 on the same side, and one or more protruding features can be set in the same axial direction to meet the requirements of higher strength or multi-point connection. In addition, different diameter combinations can be used to form diversified structures according to visual aesthetics and economy.

[0074] It should be noted that the matching components of the same size sequence also have the same protruding structure 11 and maintain a high degree of consistency at the angles that need to be matched, so that there is no interference during application.

[0075] The height of the protruding structure 11 is consistent with the opening of the pipe fitting, ensuring system-level compatibility within the same size series.

[0076] The height of the protruding structure 11 of pipe fittings of the same size sequence can be consistent in scenarios requiring them to be used together, in order to avoid assembly interference. For example:

[0077] In the shelving system, the ring-shaped expansion component can be used with pipe fittings of the same size to fix the shelves;

[0078] The high protruding structure 11 can be used to install components such as casters, but in the case of shelf fixing, the surface that is fixed to the shelf after rotating 90 degrees and engaging with the pipe joint does not interfere.

[0079] It should be understood that the above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. It should not be considered that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art to which this utility model pertains, several simple deductions or substitutions can be made without departing from the concept of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
