Description

Technical Field

[0001] This application relates to the technical field of mechanical connections and locking, and in particular to a locking component. Background Technology

[0002] In the field of dehumidifier units, with the increasing demand for air humidity control in industry and daily life, the application of dehumidifier units is becoming more and more widespread. They play a vital role in ensuring indoor environmental comfort, preventing items from getting damp and damaged, and maintaining the stability of certain industrial production environments. A high-performance dehumidifier unit can effectively remove excess moisture from the air, improve air quality, and thus create healthier and more suitable living and working conditions for people.

[0003] In the past, dehumidifier unit manufacturing typically employed welding to create the original monolithic frame to ensure load-bearing capacity. This method fuses metal materials together at high temperatures, forming a robust, integrated structure capable of withstanding significant weight and external forces. Alternatively, a modular frame approach is used, where the frame is disassembled into multiple parts and assembled on-site. This method allows for greater flexibility based on actual needs.

[0004] However, the large size of the welded frame can affect loading dimensions during transportation, leading to loading difficulties. While a modular frame can solve the transportation problem, it lacks the load-bearing capacity guarantee of the welded method during on-site assembly, and different installation methods can affect on-site installation efficiency. Utility Model Content

[0005] To effectively reduce the loading dimensions of the original integral welded frame during transportation and to achieve rapid and flexible modular installation, the purpose of this application is to provide a locking component. The technical solution adopted is as follows: Includes locking connectors, load-bearing frame body, and fasteners; The locking connector is connected to the load-bearing frame body by a plug-in method, wherein every two load-bearing frame bodies are arranged perpendicularly to each other and are connected by a locking connector to form the corner of the frame; The fastener is located at the connection between the locking connector and the load-bearing frame body, and the fastener is used to detachably fix the locking connector to the load-bearing frame body.

[0006] By adopting the above technical solution, a simple and quick assembly and disassembly method is provided, which greatly improves the efficiency of frame construction, effectively reduces the loading size of the original integral welded frame in the transportation process, facilitates transportation and storage, and ensures the stability and load-bearing capacity of the frame corners. It is suitable for application scenarios that require frequent assembly and disassembly, such as temporary supports, display racks or building templates, thereby reducing the cost of use and enhancing flexibility.

[0007] Optionally, the locking connector includes a right-angle member and two insertion tubes, the two insertion tubes being perpendicular to each other and fixedly connected, and the right-angle member being fixed at the connection point of the two insertion tubes to enhance the connection strength.

[0008] By adopting the above technical solution, the right-angle component, as a reinforcing part, significantly improves the rigidity and torsional resistance of the connection point, preventing the connector from deforming or breaking when subjected to heavy loads or external impacts, thereby enhancing the structural stability and safety of the overall frame. It is especially suitable for high-load environments such as industrial shelves or large equipment supports, and extends the service life.

[0009] Optionally, the right-angled member is provided with a through hole for fixing the right-angled member to two plug tubes via spot welding.

[0010] By adopting the above technical solution, spot welding is performed through through holes, which ensures the accuracy and firmness of the welding position, simplifies the manufacturing process, reduces production costs and time, avoids damage to the connector material caused by excessive welding, maintains the overall strength and aesthetics of the connector, is suitable for mass production, and improves product consistency and reliability.

[0011] Optionally, the insertion tube is provided with a limiting hole, the limiting hole including a horizontally extending transverse groove, such that the two sides of the limiting hole form a limiting plate that can be elastically bent.

[0012] By adopting the above technical solution, the elastic characteristics of the limiting plate allow for a certain buffer and self-adaptive capability when installing fasteners, which facilitates alignment and insertion, reduces assembly difficulty, and at the same time, the limiting plate can generate a continuous clamping force after tightening, effectively preventing fasteners from loosening and improving the reliability and seismic performance of the connection under vibration or dynamic load.

[0013] Optionally, the load-bearing frame body is provided with a positioning threaded hole, which is coaxially corresponding to the limiting hole, and the fastener passes through the positioning threaded hole and the limiting hole.

[0014] By adopting the above technical solution, the coaxial design of the positioning threaded hole and the limiting hole ensures that the fastener can be inserted and fixed accurately and smoothly, reducing the adjustment and error during assembly, improving assembly efficiency and accuracy, while ensuring the centering of the connection point and uniform force distribution, avoiding local wear caused by stress concentration, and enhancing the overall stability of the frame.

[0015] Optionally, the fastener includes a bolt and a nut, both the head of the bolt and the nut being frustoconical, with the conical surface of the bolt head facing opposite directions to the conical surface of the nut.

[0016] By adopting the above technical solution, the frustum-shaped head and nut can automatically align during tightening, simplifying the installation process, reducing tool dependence, and the conical contact provides a larger friction area and wedging effect, enhancing the anti-loosening performance and ensuring that the connection remains tight even in long-term use or vibration environments, thus improving safety and maintenance convenience.

[0017] Optionally, the head of the bolt abuts against the inner surface of the insertion tube, and the edge of the limiting plate contacts the conical surface of the nut.

[0018] By adopting the above technical solution, the contact between the conical surface of the bolt head and nut and the edge of the limiting plate forms a multi-point locking mechanism, which disperses the force at the connection point, reduces local stress and wear, and at the same time, the elastic deformation of the limiting plate allows for small displacement compensation, adapts to thermal expansion and contraction or load changes, improves the durability and adaptability of the connection, and is suitable for applications in harsh environments.

[0019] Optionally, after assembly, the outer surfaces of the nut, the main body of the load-bearing frame, and the right-angled piece are flush.

[0020] By adopting the above technical solution, the flush surface makes the frame look neat and smooth, avoiding potential safety hazards caused by protruding parts, such as scratching people or hindering operation. At the same time, it is easy to clean, maintain and package, improving the aesthetics of the product and the user experience. It is especially suitable for occasions with high requirements for appearance, such as furniture or public facilities.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. It provides a simple and quick assembly and disassembly method, which greatly improves the efficiency of frame construction, effectively reduces the loading size of the original integral welded frame in the transportation process, facilitates transportation and storage, and ensures the stability and load-bearing capacity of the frame corners. It is suitable for application scenarios that require frequent assembly and disassembly, such as temporary supports, display racks or building templates, thereby reducing the cost of use and enhancing flexibility. 2. By introducing right-angle components and reinforcing them with spot welding, the structural strength and deformation resistance of the components are significantly improved. The unique design of the limiting holes and elastic limiting plates, combined with bolts and nuts with tapered surfaces, not only simplifies the installation and alignment process but also forms a fastening mechanism with anti-loosening and vibration-resistant functions, ensuring the long-term stability and safety of the connection under dynamic loads. 3. The design of fasteners flush with the surface of the load-bearing frame and connectors eliminates safety hazards caused by protrusions and makes the appearance cleaner and smoother. These features work together to make the component not only sturdy and durable and easy to install, but also to broaden its application scenarios and improve the overall quality of the final product and the user experience.

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0024] A locking component, as shown in the reference Figure 1 The system includes a locking connector 1, a load-bearing frame body 2, and fasteners 3. The locking connector 1 is connected to the load-bearing frame body 2 via a plug-in connection. The two load-bearing frame bodies 2 are perpendicular to each other and connected by a locking connector 1 to form the corners of the frame. Fasteners 3 are located at the connection point between the locking connector 1 and the load-bearing frame body 2, used to detachably fix the locking connector 1 to the load-bearing frame body 2. This achieves the effect of facilitating transportation while ensuring load-bearing capacity and installation efficiency. This is because the detachable connection method allows the frame to be disassembled during transportation, reducing the loading size, while the self-tensioning positioning and locking functions ensure load-bearing capacity and installation efficiency after on-site installation.

[0025] Furthermore, refer to Figure 2 The locking connector 1 includes a right-angle member 11 and two insertion tubes 12. The two insertion tubes 12 are perpendicular to each other and fixed at the connection point by welding. The right-angle member 11 is fixed at the connection point of the two insertion tubes 12 to enhance the connection strength. The right-angle member 11 is usually made of metal, possessing a certain degree of hardness and toughness, and its shape is right-angled to accommodate the two perpendicular insertion tubes 12. The right-angle member 11 can also be made of high-strength engineering plastic, which is lightweight and has a certain degree of corrosion resistance. The connection between the right-angle member 11 and the insertion tubes 12 can be welded or connected using bolts 31 or other connectors. The insertion tubes 12 are generally made of metal, with a rectangular cross-section, providing good load-bearing capacity. The insertion tubes 12 can also be made of aluminum alloy, which is lightweight and has high strength. The two insertion tubes 12 are fixed perpendicularly to each other by welding or riveting. Welding makes the connection more secure, while riveting facilitates disassembly and replacement. The right-angle piece 11 is fixed at the connection of the two insertion pipes 12. By increasing the structural strength of the connection part, the locking connector 1 is more stable as a whole and can withstand greater external forces.

[0026] Furthermore, refer to Figure 3 The right-angled member 11 has a through hole 111 for spot welding to fix the right-angled member 11 to the two insertion tubes 12. The through hole 111 is generally circular, and its diameter is determined according to the requirements of the spot welding process. The through hole 111 can also be square, elliptical, or other shapes. Spot welding is a commonly used welding method. By spot welding at the through hole 111, the right-angled member 11 and the insertion tubes 12 can be tightly connected together. This connection method is not only strong but also relatively simple to operate, which can improve production efficiency. After the right-angled member 11 and the insertion tubes 12 are fixed by spot welding, they form a whole, further enhancing the structural stability of the locking connector 1.

[0027] Optionally, the connection between the right-angle piece 11 and the insertion tube 12 of the locking connector 1 can also be achieved by riveting instead of spot welding. The right-angle piece 11 and the insertion tube 12 are respectively provided with corresponding riveting holes, and they are fixed together by passing rivets through the riveting holes.

[0028] The right-angle piece 11 and the insertion tube 12 are connected by riveting, making the connection process more flexible and facilitating disassembly and replacement of parts. Riveting offers advantages in situations requiring frequent disassembly and assembly. Simultaneously, riveting ensures the connection strength between the right-angle piece 11 and the insertion tube 12, meeting the usage requirements of the locking connector 1 and further improving the applicability and maintainability of the locking component.

[0029] Furthermore, refer to Figure 3The connector 12 has a limiting hole 121, which includes a horizontally extending transverse groove 1211, forming elastically bendable limiting plates 122 on both sides of the limiting hole 121. The limiting hole 121 is designed to cooperate with the fastener 3 to achieve a locking function. The limiting hole 121 is typically machined on the connector 12 using processes such as drilling or stamping. The transverse groove 121 allows the elastically bendable limiting plates 122 on both sides of the limiting hole 121, which have a certain degree of elasticity and can deform elastically when subjected to external force. The elasticity of the limiting plates 122 can be adjusted according to the material and thickness of the connector 12. The design of the limiting hole 121 and the limiting plates 122 provides a basis for subsequent cooperation with the fastener 3, making the locking process more reliable.

[0030] Furthermore, refer to Figure 4 The load-bearing frame body 2 is provided with a positioning threaded hole 21, which is coaxially corresponding to the limiting hole 121. The fastener 3 passes through the positioning threaded hole 21 and the limiting hole 121. The positioning threaded hole 21 is pre-machined on the load-bearing frame body 2, and its thread specification matches that of the fastener 3. The coaxial correspondence between the positioning threaded hole 21 and the limiting hole 121 ensures that the fastener 3 can pass through smoothly. This correspondence allows the load-bearing frame body 2 to be accurately connected to the locking connector 1, ensuring the assembly accuracy of the entire frame. Through the cooperation of the positioning threaded hole 21 and the limiting hole 121, the fastener 3 can tightly connect the load-bearing frame body 2 and the locking connector 1 together.

[0031] Furthermore, refer to Figure 5 Fastener 3 includes a bolt 31 and a nut 32. Both the head of bolt 31 and the nut 32 are frustoconical, with the conical surface of the bolt 31's head facing opposite directions to the conical surface of the nut 32. Bolt 31 and nut 32 are typically made of metal, possessing high strength and wear resistance. The frustoconical design of the bolt 31's head allows for better contact with the inner surface of the connector 12, increasing the contact area and improving connection stability. The frustoconical design of the nut 32, with its conical surface facing opposite directions to the conical surface of the bolt 31's head, allows the limiting plate 122 to elastically deform when tightened, thus achieving self-tensioning positioning and locking functions. The combined use of bolt 31 and nut 32 effectively secures the load-bearing frame body 2 and the locking connector 1 together.

[0032] Furthermore, refer to Figure 5The head of bolt 31 abuts against the inner surface of connector 12, and the edge of limiting plate 122 contacts the conical surface of nut 32. After bolt 31 passes through the positioning threaded hole 21 and limiting hole 121, the head of bolt 31 tightly abuts against the inner surface of connector 12, providing a stable support point. The edge of limiting plate 122 contacts the conical surface of nut 32. When nut 32 is tightened, the conical surface of nut 32 exerts an outward thrust on limiting plate 122, causing limiting plate 122 to elastically bend, thereby achieving self-tensioning positioning and locking. This contact method makes the locking process more reliable and effectively prevents the connector from loosening.

[0033] Furthermore, after assembly, the outer surfaces of the nut 32, the load-bearing frame body 2, and the right-angle piece 11 are flush. This flush design makes the entire frame's outer surface smoother, which is not only aesthetically pleasing but also more convenient in actual use. For example, when installing other components, there will be no interference due to uneven surfaces. At the same time, the flush design also helps to improve the overall stability of the frame.

[0034] In use, the two insertion tubes 12 of the locking connector 1 are inserted into the grooves inside the two load-bearing frame bodies 2, forming a corner of the frame. At this time, the edge of the load-bearing frame body 2 is flush with the outer surface of the right-angle piece 11 of the locking connector 1. Then, the fastener 3 is inserted into the positioning threaded hole 21 on the load-bearing frame body 2, passing through the limiting hole 121. The head of the bolt 31 of the fastener 3 abuts against the inner surface of the insertion tube 12. The insertion tube 12 at the abutment point deforms outward, and the deformed insertion tube 12 also abuts tightly against the inner surface of the load-bearing frame body 2. The conical surface of the nut 32 generates an outward pushing force on the limiting plate 122, causing the limiting plate 122 to bend elastically. The limiting plate 122 and the deformed insertion tube 12 cooperate to achieve self-tensioning positioning and locking. At this time, the outer surface of the nut 32 is flush with the outer surface of the load-bearing frame body 2. Finally, the multiple corners are assembled to form a large load-bearing frame.

[0035] The implementation principle of this embodiment is as follows: The locking component in this embodiment, through the cooperation of the locking connector 1, the load-bearing frame body 2, and the fastener 3, enables rapid docking and installation of the dehumidifier unit's connector pipe 12 load-bearing frame at the assembly site. The detachable connection method solves the problem of difficult transportation of the original integral welded frame, effectively reducing the loading dimensions during transportation. Furthermore, the customized fastener 3 utilizes the micro-deformation control of the metal material under different fit allowance conditions to achieve self-tensioning positioning and locking functions, ensuring the load-bearing capacity and installation efficiency after on-site installation. Compared with existing technologies, this has significant advantages, improving the practicality and economy of the dehumidifier unit.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
