Description

Tool-free quick-assembly structure of profile frame Technical Field

[0001] This utility model relates to the field of exhibition and display, specifically to a tool-free quick-assembly structure for a profile frame. Background Technology

[0002] In the exhibition and display industry, display props typically include display cases and display stands, which are mainly used to display goods and attach promotional advertisements to achieve better product promotion. Therefore, the construction of display cases and stands is crucial for businesses. Due to the needs of exhibition and display settings, the construction of display cases and stands must be structurally sound, aesthetically pleasing, and capable of free assembly, quick disassembly, and convenient transportation.

[0003] Currently, the main material used for constructing display cases and stands on the market is aluminum profile. Aluminum profiles are processed into various shapes and then spliced ​​together to form the required frame. However, the current connection process for aluminum profiles mainly uses bolt assemblies, fasteners, plug-in connectors, and various installation tools for assembly. This is not only time-consuming and labor-intensive, but also inconvenient to transport due to the large number of parts. For example, patent 202221214977.X discloses an industrial aluminum profile modular frame structure, including vertical aluminum profile plates: connecting fasteners are installed on both the upper and lower surfaces of the vertical aluminum profile plates, and vertical splicing mechanisms are provided on the surfaces of the connecting fasteners; horizontal splicing mechanisms are provided on the surfaces of the horizontal aluminum profile plates; and assembly mechanisms are provided on the surfaces of the vertical aluminum profile plates. 202211425483.0 This invention discloses a high-strength aluminum profile structure, including an aluminum profile frame device. The aluminum profile frame device includes a frame body, a splicing reinforcement mechanism, a locking device, and a triangular reinforcement plate. The frame body is surrounded by four sets of aluminum substrates. The outer surface of the aluminum substrates is processed with four sets of guide grooves. The splicing reinforcement mechanism is located at the corner of the frame body and includes a splicing plate one and a splicing plate two. Summary of the Invention

[0004] The purpose of this utility model is to provide a tool-free quick-assembly structure for profile frames, so as to solve the problems mentioned in the background art, such as time-consuming and labor-intensive installation during the existing frame construction process, inconvenient transportation due to the large number of parts, and poor versatility.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A tool-free quick-assembly structure for a profile frame includes a connector and a profile. The profile has a through cavity along its length and multiple through holes along its length. The connector has a transition section and a connecting section connected to the transition section.

[0007] The external shape of the connecting section matches the cross-section of the profile cavity; the connecting section is a hollow structure, and its hollow cavity is divided into an inner cavity and an outer cavity by a support plate; at least one connecting hole is provided on the inner wall of the inner cavity shown.

[0008] A locking mechanism is provided, which is installed and fixed in the inner cavity by a support plate and corresponds to the connection hole;

[0009] When the connector is connected to the profile, the connecting section of the connector is inserted into the through cavity of the profile. By controlling the locking mechanism, the locking mechanism protrudes and passes through the connecting hole and the corresponding mounting through hole on the profile, thereby connecting the two.

[0010] As a preferred embodiment of this utility model, in order to make the structure simpler, more practical and easier to operate, the locking mechanism shown includes a fixed carrier and a positioning tongue. The fixed carrier and the positioning tongue are connected by a thread, and the positioning tongue can be made to protrude outward by rotating the positioning tongue.

[0011] As a further improvement of this utility model, in order to make the structure more stable after connection and increase the connection strength, the positioning tongue has a circular cross-section, and its outer diameter matches the inner diameter of the mounting through hole and the connecting hole.

[0012] As a further improvement of this utility model, in order to prevent the positioning tongue from detaching from the fixed carrier during rotation, the positioning tongue includes a cylindrical body and a convex ring formed by radius contraction. The radius of the connecting hole is larger than the radius of the mounting through hole. The radius of the cylindrical body matches the connecting hole, and the radius of the convex ring matches the mounting through hole.

[0013] In order to achieve tool-free operation and quick installation, and to reduce the number of parts in the installation process, as a preferred embodiment of this utility model, a handle is provided on the outer convex end face of the positioning tongue, and the handle and the positioning tongue are an integral structure.

[0014] In order to achieve tool-free operation and quick installation, and to reduce the number of parts in the installation process, as another preferred embodiment of this utility model, a flip cover is provided on the outer convex end face of the positioning tongue, and the flip cover is connected to the positioning tongue by a positioning pin.

[0015] The advantages of this utility model are:

[0016] This utility model simplifies the structure to the greatest extent and reduces the number of parts. The quick-connect structure design enables rapid connection and disassembly, improving the convenience of operation.

[0017] This invention enables tool-free operation during rapid assembly and disassembly, reducing the time required for assembly and disassembly and improving work efficiency.

[0018] This invention enables modular and large-scale production, and the frame can be built using only three components, which greatly reduces production costs and improves transportation efficiency, and can be reused repeatedly. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0027] In the description of this invention, it should be noted that the terms "center", "inner", "outer", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example 1

[0029] Referring to Figures 1 and 3, this embodiment describes in detail a quick-installation structure for a rectangular frame. The rectangular frame includes two sets of profiles 2 of different lengths and connectors 1. The two sets of profiles of different lengths respectively form the long side and the short side of the frame, and the corners of the long and short side are connected by connectors 1. In this embodiment, the long and short side have the same cross-sectional structure. As shown in Figures 2 and 3, a through cavity 22 is provided inside the profile 1 along the length direction, and multiple mounting through holes 21 are evenly distributed on the profile along the length direction, penetrating the inner and outer sides of the profile.

[0030] As shown in Figures 3 and 4: the connector has a transition section 12 and a connecting section 11 connected to the transition section; in this embodiment, the two connecting sections 11 form a right-angle connection structure through the transition section 12; of course, through the design of the transition section 12, the two connecting sections 11 can form any angle, which will not be discussed in detail here. In order to save costs and meet structural design requirements, as shown in Figures 3 and 4: in this embodiment, the connecting section 11 is a hollow structure, and the hollow cavity is divided into an inner cavity 15 and an outer cavity 14 by a support plate 13; in order to install the locking mechanism, a connecting hole is provided on the inner wall of the inner cavity.

[0031] As shown in Figure 2, since the connecting section 11 needs to be inserted into the cavity 22 of the profile when connecting, the external structure of the connecting section 11 matches the cross section of the cavity 22 of the profile.

[0032] As shown in Figure 5: The locking mechanism 3 involved in this embodiment includes a fixed carrier 31, a positioning tongue 32, and a flip cover 34. The fixed carrier 31 is a circular base. The positioning tongue 32 includes a cylindrical body 321 and a convex ring 322 formed by radius contraction. The positioning tongue 32 is sleeved on the circular base through the cylindrical body 321. The circular base has a certain height. The flip cover 34 is provided on the convex ring 322. The flip cover 34 is connected to the convex ring through a positioning pin 33. By touching the flip cover 34, the flip cover can be rotated around the positioning pin 33 and erected. In this way, the positioning tongue 32 can be rotated by rotating the flip cover 34, thereby achieving the purpose of tool-free operation.

[0033] As shown in Figure 4, the bottom of the fixed carrier 31 is fixed to the support plate 13 by screws 4. The positioning tongue 32 is threadedly connected to the fixed carrier 31. The position of the positioning tongue is directly opposite the connection hole so that the convex ring of the positioning tongue can quickly pass through.

[0034] To prevent the positioning tongue 32 from falling off the fixed carrier 31, this embodiment reduces the radius of the mounting through hole 21 and matches the radius of the mounting through hole 21 with the radius of the convex ring 322 of the positioning tongue. In this way, when the convex ring 322 protrudes outward through the connecting hole and the mounting through hole 21, it cannot pass through the mounting through hole 21 because the radius of the cylindrical body 321 of the positioning tongue is large. This locks the position of the protruding positioning tongue and achieves the above-mentioned purpose.

[0035] As shown in Figure 2, when the connector 1 is connected to the profile 2, the connecting section 11 of the connector is inserted into the through cavity 22 of the profile. By rotating the positioning tongue 32, the convex ring of the positioning tongue protrudes outward and passes through the connecting hole and the mounting through hole 21 of the profile, thereby realizing the connection between the connector 1 and the profile 2.

[0036] For ease of installation and aesthetic purposes, a positioning step is provided between the connecting section 11 and the transition section 12. The distance from the center of the connecting hole on the connecting section 11 to the positioning step matches the distance from the center of the mounting through hole on the profile 2 to the end of the profile on the same side. Thus, when the connecting section 11 is inserted into the final position, the connecting hole corresponds exactly to the position of the set mounting through hole 21.

[0037] The connection hole on the connecting section 11 is provided to simplify the structure. To make the connection more secure, the number of connection holes can be increased so that multiple locking mechanisms 3 can be installed.

[0038] Example 2

[0039] As shown in Figures 6 and 7, this embodiment 2 modifies the locking mechanism 3 based on embodiment 1. The locking mechanism includes a fixed carrier 31 and a positioning tongue 32. The positioning tongue includes a cylindrical body 321 and a convex ring 322 formed by radius contraction. The outer end of the convex ring 322 forms a closed end face, and a handle 323 is formed on the closed end face. Thus, the positioning tongue 32 can be directly rotated through the handle 323.

[0040] During assembly, first fix the locking mechanism 3 in the connecting hole, then insert the connecting section into the corresponding frame profile, and rotate the positioning tongue counterclockwise by hand until it presses against the profile. During disassembly, rotate the positioning tongue clockwise to the corresponding position.

[0041] To further improve lock assembly efficiency, the threads between the fixing carrier and the positioning tongue adopt a large pitch structure, thereby reducing the back-and-forth movement distance.

[0042] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
