Description

Technical Field

[0001] This utility model belongs to the field of connection components for pipe fitting assembly structures, and specifically relates to a multi-directional connection component for connecting pipe fittings. Background Technology

[0002] In the construction of small structures such as prefabricated greenhouses, sunrooms, small display racks, and folding furniture, the connection between pipes is crucial for achieving structural stability and diverse forms. Currently, most prefabricated greenhouses or sunrooms in the industry use traditional bolt connections or welding methods for pipe connections.

[0003] While bolted connections are detachable, they require precise threaded holes or through holes to be pre-drilled on the pipe ends or connectors. During installation, the holes must be aligned and tools used for tightening, making the process cumbersome, inefficient, and time-consuming. Welding, on the other hand, provides a strong and permanent connection, but its construction requires specialized equipment and personnel, it is not detachable, and lacks flexibility.

[0004] Therefore, we propose a multi-directional connection assembly for pipe fitting to pipe fitting connection to solve the above problems. Utility Model Content

[0005] In response to the problem that most pipe connections in the industry for assembled greenhouses, sunrooms, and folding furniture use traditional bolt connections or welding methods, which are cumbersome and have low assembly efficiency, this utility model provides a multi-directional connection component for pipe-to-pipe connections.

[0006] The solution adopted by this utility model to solve its technical problem is: a multi-directional connection component for connecting pipe fittings, including a central base and N docking sleeves, each of the docking sleeves being fixedly installed inside the open end of a pipe fitting, the outer surface of the central base having N plugs to form a multi-directional connection angle, and the N plugs of the central base corresponding to the N docking sleeves respectively.

[0007] The shape and size of the connector of the central base are matched with the internal cavity of the docking sleeve, so that the connector of the central base is tightly inserted into the docking sleeve, thereby realizing the quick connection between the pipe and the central base, and achieving quick connection and separation of the pipes through the central base.

[0008] Preferably, the connector of the central base has a tapered structure.

[0009] Preferably, the inner cavity of the mating sleeve is a conical cavity adapted to the conical structure of the plug connector of the central base.

[0010] Preferably, the number N of the connectors in the central base is at least two, and the number N of the mating sleeves corresponds to the number of connectors in the central base.

[0011] Preferably, a detachable locking mechanism is provided between the plug of the central base and the mating sleeve. When the plug of the central base is inserted into the mating sleeve, the locking mechanism can prevent the two from axially separating.

[0012] Preferably, the outer walls of the connecting sleeve and the pipe fitting are respectively provided with coaxial positioning holes, and the plug of the central base is provided with fixing holes at the positions corresponding to the positioning holes.

[0013] Preferably, the locking mechanism is a positioning pin disposed in the positioning hole and the fixing hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model adopts a structure of "precise matching of shape and size" between the plug of the central base and the connecting sleeve at the end of the pipe fitting. The connecting sleeve can be directly inserted into the corresponding plug of the central base to complete the tight connection. Under the action of friction, the connecting sleeve and the plug of the central base are not easy to separate. This eliminates the precise hole alignment and tool tightening process required by traditional bolt connections, as well as the professional equipment and personnel required for welding. The pipe fitting and the central base can be directly and quickly inserted and separated, which greatly simplifies the operation process and reduces time and labor costs. It is especially suitable for the rapid construction needs of small structures such as assembled greenhouses, sunrooms, and small display racks.

[0016] 2. This utility model allows for the connection of pipe fittings in multiple directions by distributing multiple connectors on the central base, enabling the flexible construction of frame structures of various angles and shapes (such as the top corners of greenhouses and sunrooms, and the connection points of side columns). This design meets the morphological requirements of diverse products while ensuring the structural strength and overall stability at the nodes.

[0017] 3. This utility model, through the combined design of the raised guide structure and the concave guide groove, enables the directional insertion of the connector and the mating sleeve of the central base, preventing misalignment and making the subsequent installation of the positioning pin more convenient.

[0018] 4. This utility model further fixes the pipe fittings, connecting sleeves and the plug of the central base by positioning pins, which effectively prevents the connecting sleeves and the plug of the central base from accidentally coming apart after connection, ensuring the safety and reliability of the structure during use, while maintaining the advantage of quick disassembly.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please see Figure 1-5 This utility model provides a technical solution for a multi-directional connection assembly for connecting pipe fittings:

[0027] Example 1:

[0028] according to Figure 1-5 As shown, it includes a central base 1 and N connecting sleeves 3. Each connecting sleeve 3 is fixedly installed inside the open end of a pipe fitting 4. The outer surface of the central base 1 has N plugs 2 to form multi-directional connection angles. The N plugs 2 are respectively set to N connecting sleeves 3, allowing the pipe fitting 4 to be connected in multiple directions. It can flexibly construct frame structures of various angles and shapes (such as the top corners of greenhouses and sunrooms, and the connection of side columns). This design meets the form requirements of diverse products, while ensuring the structural strength and overall stability at the nodes.

[0029] In this embodiment, the number N of connectors 2 is at least two, and the number N of mating sleeves 3 is at least two.

[0030] The shape and size of the plug 2 match the internal cavity of the mating sleeve 3, allowing the plug 2 to be tightly inserted into the mating sleeve 3, thus achieving a tight connection. Under the action of friction, the mating sleeve 3 and the plug 2 are not easily separated, eliminating the need for precise hole alignment and tool tightening required by traditional bolt connections, as well as the professional equipment and personnel required for welding. The fitting 4 and the central base 1 can be directly and quickly inserted and separated, greatly simplifying the operation process and reducing time and labor costs. It is especially suitable for the rapid assembly needs of small structures such as assembled greenhouses, sunrooms, and small display racks.

[0031] Example 2:

[0032] Based on Example 1, such as Figure 1and Figure 4 As shown, the connector 2 has a tapered structure, and the outer circumferential surface of the connector 2 is provided with at least one set of protruding guide structures 5, which are protruding guide strips.

[0033] The inner cavity of the mating sleeve 3 is a conical cavity adapted to the conical structure. The inner wall of the conical cavity is provided with a concave guide groove 6 adapted to the protruding guide structure 5. The protruding guide structure 5 and the concave guide groove 6 cooperate to realize the directional insertion of the plug 2 and the mating sleeve 3, prevent misalignment, and make the subsequent installation of the positioning pin more convenient.

[0034] Example 3:

[0035] Based on Example 1, such as Figure 3 and Figure 5 As shown, a detachable locking mechanism is also provided between the plug 2 and the mating sleeve 3. When the plug 2 is inserted into the mating sleeve 3, the locking mechanism can prevent the two from axially separating.

[0036] Coaxial positioning holes 7 are respectively opened on the outer walls of the connecting sleeve 3 and the pipe fitting 4. The plug 2 is provided with a fixing hole 8 corresponding to the positioning hole 7. The locking mechanism is a positioning pin set in the positioning hole 7 and the fixing hole 8. The positioning pin further fixes the pipe fitting 4, the connecting sleeve 3 and the plug 2, effectively preventing the connecting sleeve 3 and the plug 2 from accidentally disengaging after connection, ensuring the safety and reliability of the structure during use, while maintaining the advantage of quick disassembly.
