Description

Technical Field

[0001] This utility model relates to the field of advertising display frame technology, specifically a connector and its frame assembly structure. Background Technology

[0002] In the field of advertising display, large advertising banners usually need to be fixed to a frame structure to achieve a good visual presentation effect.

[0003] If the entire assembly is pre-assembled in the warehouse or production site and then transported to the exhibition site, it will face problems such as handling difficulties, high transportation costs, and easy damage. Therefore, the industry practice generally adopts the method of on-site assembly, that is, after the frame is transported to the exhibition site, the frame is assembled into a whole, and then the advertising cloth is fixed to the frame piece by piece.

[0004] However, in some applications, to improve installation efficiency or protect the surface of the advertising cloth, it is pre-fixed to some frame units to form "frame modules with cloth." When these frame modules with the advertising cloth installed need to be spliced ​​with other frame components on site, the advertising cloth itself will block the connection points, causing physical obstacles to the splicing operation.

[0005] Therefore, in order to address the above problems, there is an urgent need to provide an improved frame connection structure or splicing method that can effectively avoid fabric interference when the advertising cloth is already fixed, simplify the on-site splicing process, improve assembly speed and reliability, and meet the needs of modern advertising displays for efficient deployment and high-quality presentation. Utility Model Content

[0006] To address the technical problems in the background art, this utility model discloses a connector and its frame assembly structure.

[0007] This utility model provides a connector, including a main body; One end of the main body is provided with a connecting part, which is configured to be connected and fixed to the frame when the connector is inserted into the frame, and the main body is configured to have its rotational freedom restricted when the connector is inserted into the frame; The other end of the main body is provided with a hook to enable the interlocking of the connecting parts.

[0008] Furthermore, the main body forms a surface connection with the frame when the connector is inserted into the frame.

[0009] Furthermore, the connecting part is connected and fixed to the frame by a snap-fit ​​connector.

[0010] Furthermore, the connecting part has a slot; The snap-fit ​​component snaps into the slot to restrict the axial freedom of the connector; When the connector is inserted into the frame, the frame is confined between the hook of the connector and the snap-fit.

[0011] Furthermore, the snap-fit ​​connector has an opening; The opening snaps into the slot of the connecting part.

[0012] Furthermore, the opening is composed of an arc-shaped groove at the bottom and a straight groove at the opening end; When the snap-fit ​​component engages with the connecting part, the open end of the opening converges into the slot to prevent the snap-fit ​​component from disengaging.

[0013] Furthermore, the hook is offset at one end of the main body.

[0014] Furthermore, a radially extending extension is provided at the connection point between the hook and the main body.

[0015] This utility model also provides a frame assembly structure, including a first frame and a second frame; Both the splicing ends of the first frame and the second frame are equipped with connectors according to any one of the claims; The connectors of the first frame and the connectors of the second frame are installed inverted relative to each other. The hooks of the connectors on the first and second frames protrude from the frames. When the first and second frames are spliced ​​together, the hooks of the connectors on the first frame and the hooks of the connectors on the second frame engage with each other to achieve a hook connection.

[0016] Furthermore, the first frame and the second frame are provided with insertion holes; The main body of the plug hole and connector is modeled.

[0017] Furthermore, the length of the protruding groove of the hook is configured such that when the hook is engaged, the splicing end faces of the first frame and the second frame fit together.

[0018] The beneficial effects of this utility model are: 1. This utility model utilizes a dedicated connector with connecting parts and hooks, employing a method where the hook openings face each other and are staggered along the opening direction, allowing adjacent frame modules to be quickly connected even when the advertising cloth is pre-fixed. This structure effectively avoids the obstruction and interference of the advertising cloth on traditional bolt or plug-in connection methods, solving the assembly difficulties caused by the cloth covering the frame modules during on-site assembly.

[0019] 2. The connectors can be securely connected by push-in staggered snap-fit, without the need for additional tools or complex alignment operations. This significantly simplifies the on-site assembly process, reduces manual labor time, and improves the overall assembly speed of the advertising frame system, meeting the needs of modern advertising displays for efficient deployment.

[0020] 3. The connector has a simple structure and strong versatility. It is suitable for advertising frame systems of various materials and sizes, and can be arranged at multiple connection nodes of the frame according to actual needs. It supports multi-directional expansion and splicing, and can flexibly adapt to advertising display scenarios of different scales and forms.

[0021] 4. The connector in this utility model is an independent component. Compared with the structure in which the connector is integrally formed on the frame, it has the following advantages: a. It simplifies the structure of the frame and reduces the processing cost of the frame; b. It avoids the frame from breaking when it is impacted during transportation; c. When the connector is damaged, a new connector can be replaced instead of replacing the entire frame, which further reduces costs. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] Example 1: like Figure 1-4 As shown, this utility model discloses a connector, including a main body 1, one end of which is provided with a connecting part 13 and the other end is provided with a hook part 12.

[0026] When the connector is inserted into the frame, the main body 1 forms a surface connection with the frame to restrict the rotational freedom of the main body 1. In this embodiment, the cross-section of the main body 1 is oblong, but in other embodiments it may be elliptical or flattened round.

[0027] The connecting part 13 is provided with an annular groove 11, which is located inside the frame and engages with a snap-fit ​​member 2. The snap-fit ​​member 2 is an arc-shaped plate with a U-shaped opening 21. The opening 21 engages with the groove 11, and the hook part 12 is offset at one end of the main body 1, so that the frame is confined within the hook part 12 and the snap-fit ​​member 2, thereby restricting the degree of freedom of the connector insertion direction. At the connection position between the hook part 12 and the main body 1, there is a radially extending extension 14, which fits against the frame and can further restrict the degree of freedom of the connector insertion direction. To prevent the snap-fit ​​member 2 from falling off the groove 11, the opening 21 is composed of an arc-shaped groove 211 at the bottom and a straight groove 212 at the opening end; the diameter of the arc-shaped groove 211 is the same as the diameter of the bottom of the groove 11; the walls of the straight groove 212 are parallel, and their spacing is smaller than the diameter of the arc-shaped groove 211. With this configuration, when the straight groove 212 engages with the slot 11, it will deform and open; when the straight groove 212 passes over the slot 11 and the arc groove 211 engages with the slot 11, the straight groove 212 acts as a blocking mechanism to prevent the engaging part 2 from falling off the slot 11.

[0028] The flat groove 212 makes it difficult for the snap fastener 2 to snap into the slot 11. The flat groove 212 has a small contact area with the hand and not enough operating space, making it difficult to push and pull the snap fastener 2. Therefore, a protruding plate 22 is vertically provided on the opening end of the snap fastener 2 facing away from the opening 21 to provide enough gripping area for the hand to push and pull the snap fastener 2.

[0029] The hook 12 is U-shaped. The main body 1 and the center of the outer side of one of the side arms of the hook 12 are integrally formed and connected. The side arm connected to the main body 1 covers the main body 1 in the projection along the length direction, so as to play an effective blocking role, making the frame structure between the hook 12 and the snap fastener 2 more robust.

[0030] The connectors are installed upside down at the splicing ends of adjacent frames, so that the openings of the hooks 12 face opposite directions. The two connectors are locked together by the openings of the hooks 12 facing each other and interlocking along the opening direction of the hooks 12, thereby achieving the locking and fixing of adjacent frames.

[0031] Compared to existing technologies, the advantages of this embodiment are: 1. This utility model, by setting a dedicated connector with connecting parts and hooks 12, and using a method where the hooks 12 have opposite openings and are staggered along the opening direction, allows adjacent frame modules to be quickly connected even when the advertising cloth is pre-fixed. This structure effectively avoids the obstruction and interference of the advertising cloth on traditional bolt or plug-in connection methods, and solves the assembly difficulties caused by the cloth covering when assembling frame modules with cloth on site. 2. The connectors can achieve a stable connection through push-in staggered snap-fit, without the need for additional tools or complex alignment operations, significantly simplifying the on-site assembly process, reducing manual labor time, and improving the overall assembly speed of the advertising frame system, meeting the needs of modern advertising displays for efficient deployment. 3. The connector has a simple structure and strong versatility, is suitable for advertising frame systems of various materials and sizes, and can be arranged at multiple connection nodes of the frame according to actual needs, supporting multi-directional expansion splicing, and flexibly adapting to advertising display scenarios of different scales and forms. 4. The connector in this utility model is an independent component. Compared with the structure in which the connector is integrally formed on the frame, it has the following advantages: a. It simplifies the structure of the frame and reduces the processing cost of the frame; b. It avoids the frame from breaking when it is impacted during transportation; c. When the connector is damaged, a new connector can be replaced instead of replacing the entire frame, which further reduces costs.

[0032] Example 2: like Figure 5 and Figure 6 As shown, this utility model also discloses a frame assembly structure, including a first frame 3 and a second frame 4; the first frame 3 and the second frame 4 are not limited to a straight shape, but can also be arc-shaped or other shapes.

[0033] The splicing ends of the first frame 3 and the second frame 4 are both equipped with the connectors shown in Embodiment 1, and their specific installation structure is as follows: Figure 8 As shown, the splicing ends of the first frame 3 and the second frame 4 are provided with horizontally arranged insertion holes 5. The connector is inserted into the insertion hole 5 from the outside to the inside, so that the main body 1 is located in the insertion hole 5. The outer side of the splicing end abuts against the hook part 12, so that the hook part 12 protrudes outward from the frame. The side of the slot 11 adjacent to the main body 1 is flush with the inner side of the splicing end, and the snap fastener 2 snaps into the slot 11.

[0034] The connector installed on the first frame 3 has its hook 12 opening facing downwards, while the connector installed on the second frame 4 has its hook 12 opening facing upwards. First, the first frame 3 is raised so that the connector on the first frame 3 is positioned above the connector on the second frame 4, with the outer arm of the hook 12 of the connector on the first frame 3 aligned with the groove of the connector on the second frame 4. Then, by lowering the first frame 3, the two hooks 12 engage, thus securing the first frame 3 and the second frame 4.

[0035] If there is a gap between the first frame 3 and the second frame 4, it will reduce the connection strength between the first frame 3 and the second frame 4, and may also cause the hook 12 to break. Therefore, if... Figure 7 As shown, the splicing ends of the first frame 3 and the second frame 4 are provided with vertically extending grooves 6, and only the outer arm of the hook 12 protrudes. With this configuration, when the hook 12 is engaged, the splicing end faces of the first frame 3 and the second frame 4 fit together. Moreover, it eliminates the need for the process of aligning the two hooks 12. The splicing ends of the first frame 3 and the second frame 4 are first fitted together, and then moved, so that the two hooks 12 can be accurately engaged.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
