Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum profile edge sealing, and particularly relates to a profile edge sealing connection structure. Background Art

[0002] In existing exhibition display technology, considering the production and use costs, frames built with aluminum profiles usually do not have edge banding. However, considering the aesthetics and the sharp corners of the profiles that can easily cause damage to visitors or users, edge banding is gradually required in large-scale exhibitions.

[0003] Currently, the common methods for edge banding aluminum profiles are: 1. Gluing decorative strips to the outside of the profile; 2. Fastening the edge banding strips to the profile with screws or other fasteners. However, after installation, these edge banding methods are difficult to disassemble, and the work is laborious, time-consuming, and labor-intensive.

[0004] In addition, some edge-sealing structures that adopt plug-in, snap-in and other plug-in forms have also appeared on the market. For example, patent number 201920999911.8, named as a profile connection structure, profile and profile assembly, describes a structure in which profiles are connected by matching male and female ends, but it only relies on two raised hooks for docking, which is very inconvenient to disassemble, and the stability cannot be well guaranteed. Summary of the Invention

[0005] In order to solve the technical problem of troublesome assembly and disassembly caused by edge sealing of profiles in the prior art, the utility model aims to provide a profile connection structure which has a simple structure, is easy to assemble and disassemble, and does not require any installation tools.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a profile edge sealing connection structure, comprising a profile and an edge sealing profile, wherein a plurality of connecting holes are arranged on the profile; an edge sealing groove is provided on the opposite end surfaces of the edge sealing profile along the length direction, and the two inner sides of the edge sealing groove expand in the width direction so that the inner groove width of the edge sealing groove is greater than the width of the edge sealing groove slot; it also includes a connecting piece; the connecting piece includes a connecting piece body and an elastic protrusion; the connecting piece body has two mutually parallel side surfaces, and elastic protrusions are respectively formed at both ends of the two side surfaces, the width between the two side surfaces of the connecting piece body is adapted to the width of the edge sealing groove slot; the width between the two elastic protrusions at the same end is greater than the width of the edge sealing groove slot; the connecting piece body is also provided with two elastic clips, and the connecting piece is connected to the profile by respectively buckling the edges of the profile connection holes through the elastic clips; the connecting piece realizes an embedded connection with the edge sealing profile by squeezing the elastic protrusions so that the elastic protrusions are embedded in the edge sealing groove.

[0007] As a preferred implementation structure of the present invention: the elastic protrusion and the connector body are an integrated structure, and an elastic groove is opened between the elastic protrusion and the connector body. The elastic protrusion can be tilted by squeezing to reduce the width of the elastic groove so that the connector can be embedded in the edge sealing groove.

[0008] The above structure is simple and cleverly designed, can be integrally formed with the connector body, and has low production cost.

[0009] In order to facilitate the installation and buckling of the connecting piece, a chamfer is provided on the outer edge of the notch of the elastic protrusion.

[0010] In order to strengthen the connection strength between the connector and the profile and facilitate the connection, two positioning arcs are provided on the connector body. The two positioning arcs are located on both sides of the elastic buckle. When connected, they are respectively inserted into adjacent connecting holes and cooperate with the walls of the connecting holes.

[0011] As a further improvement of the present invention: the connecting piece is made of plastic or nylon.

[0012] As a preferred embodiment of the present invention, the elastic buckle is in an R-shaped structure, consisting of straight sides and curved sides of an integrated structure, with a deformation groove formed between the straight sides and the curved sides.

[0013] The elastic buckle can be integrally formed with the connector body, and production is convenient and quick.

[0014] Beneficial effects of the utility model:

[0015] 1. The connector structure of the utility model can be integrally formed at one time and is made of plastic or nylon material. It is quick and convenient to produce and is cheap, and can be widely promoted and used.

[0016] 2. The connecting parts are first buckled into the edge banding groove of the edge banding profile, and then connected to the profile mouth through elastic buckles. It is simple to install and easy to operate. No tools are required during the entire installation or disassembly process. It has low skill requirements for workers, is easy to use, and requires less installation time.

[0017] 3. After the utility model is connected, the profile and the edge banding profile have good bonding and high firmness, and multiple connectors can be set according to the length of the profile. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0029] It should be noted that the words "back", "front", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0030] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments.

[0031] like Figure 1 As shown: This embodiment relates to a profile edge connection structure, including a profile 1, an edge profile 2 and a connector 3; a plurality of connection holes 11 are arranged on the profile 1, and the connection holes 11 are used to connect with other profiles or components; in this embodiment, the profile 1 has been used in the construction of the profile frame. Of course, there are many ways to use this profile, and no one will be given as examples.

[0032] like Figure 4 and Figure 5 As shown: an edge sealing groove 21 is provided on the opposite end surface of the edge sealing profile 2 along the length direction, and the inner sides of the edge sealing groove 21 expand in the width direction, so that the inner groove width h1 of the edge sealing groove is greater than the width of the edge sealing groove notch h.

[0033] like Figure 2 and Figure 3 As shown: the connector 3 includes a connector body 31, an elastic protrusion 32 and an elastic buckle 36; the connector body 31 is a rectangular structure, and elastic protrusions 32 are formed on the four corners of the two side surfaces 311 of the connector body. An elastic groove 34 is provided between the elastic protrusion 32 and the connector body 31 so that only the bottom side of the elastic protrusion 32 is connected to the connector body 31. In this way, the open end of the elastic protrusion can be tilted toward the connector body 31 after being squeezed. Figures 3 to 5 As shown, the width H between the two side surfaces of the connector body matches the width h of the edge banding slot; while the width L between the two elastic protrusions 31 on the same end is greater than the edge banding slot width h and less than the inner width h1 of the edge banding slot. To facilitate snapping the connector into the edge banding slot, the outer edges of the elastic protrusions at the slot are chamfered 33.

[0034] In this embodiment, the connector body 31 and the elastic protrusion 32 are an integrally formed structure.

[0035] like Figure 2 As shown, in this embodiment, the elastic clip 36 is an R-shaped structure, consisting of a straight side 361 and a curved side 362. The straight side 361 and the curved side 362 are connected to form a single piece at the end away from the connector body. A deformation groove 364 is formed between the straight and curved sides, and a groove 363 is formed on the curved side. A rectangular hole is provided in the center of the connector body. Two elastic clips 36 are fixed upright on the two wide sides of the rectangular hole via the straight sides 361, with the curved sides 362 of the two elastic clips facing each other. In this embodiment, the distance between the grooves 363 on the two curved sides is less than the minimum distance p between adjacent connecting holes on the profile, ensuring that the curved sides expand to the sides after connection, generating an elastic force. Of course, the distance between the grooves 363 can also be equal to the minimum distance between adjacent connecting holes on the profile. If this is greater, the connector will wobble after connection. To facilitate the insertion of the elastic clip into the connecting hole, the connection between the straight and curved sides of the elastic clip is an arc.

[0036] In this embodiment, the elastic buckle 36 and the connector body 31 are integrally formed.

[0037] like Figure 2 and Figure 3 As shown: In order to achieve rapid positioning and installation of the connector 3 and the profile 1, and at the same time strengthen the connection strength between the connector and the profile, this embodiment further provides two positioning arcs 35 on the central axis of the connector body. The two positioning arcs 35 are respectively located on the left and right sides of the two elastic buckles 36. The axial distance between the two positioning arcs is adapted to the farthest distance p1 between the two adjacent holes connected. The radius of the positioning arc 35 is adapted to the radius of the connecting hole 11. Figure 6 and Figure 9 As shown, the cross-section of the positioning arc 35 is a frustum structure, with a radius at the front end that contracts to facilitate quick insertion into the connection hole, while the radius at the base of the positioning arc gradually increases to achieve a tight fit with the connection hole 11. Of course, the tight fit between the positioning arc and the connection hole is intended to ensure an optimal connection effect. If the optimal connection effect is not sought, the positioning arc can simply provide a corresponding positioning effect.

[0038] like Figures 6 to 9 As shown: When connecting, the connecting piece 3 is first pressed obliquely into the edge banding groove 21, that is, by squeezing the elastic protrusion 32 to make the elastic protrusion tilted, the connecting piece is embedded in the edge banding groove 21, thereby realizing the embedded connection with the edge banding profile 2. After embedding, since the width of the two elastic protrusions at the same end is greater than the width of the edge banding groove, it is ensured that the connecting piece will not be detached from the edge banding groove. Due to the elastic force of the elastic protrusion and the adaptation of the size width, the tightness of the connection between the connecting piece and the edge banding profile is guaranteed.

[0039] After the edge banding profile 2 is connected to the connecting piece 3, the connecting piece 3 is tightly connected to the profile 1 through the dual functions of the positioning arc 35 and the elastic snap 36, that is, the elastic snap is used to respectively buckle the two edge hole walls closest to the two adjacent connecting holes on the profile to achieve a snap connection with the profile; the positioning arc is inserted into the two adjacent connecting holes and is tightly fitted with the two edge hole walls farthest from the two adjacent connecting holes, thereby ensuring the stability of the connection between the connecting piece and the profile, and further ensuring that the two will not produce any displacement or shaking.

[0040] In this embodiment, the connecting member 3 is made of plastic integrally by injection molding, which is low in cost and the color of the plastic can be changed, so it is easy to find during installation.

[0041] It can be seen from this embodiment that the connection structure involved in this case is simple to install and easy to disassemble, and no tools are required during the entire installation or disassembly process, which greatly improves work efficiency.

[0042] The above is a description of the present invention and its implementation methods. This description is not restrictive. What is shown in the accompanying drawings is only one of the implementation methods of the present invention, and the actual structure is not limited to this. There are many ways to implement the elastic protrusion. For example, holes can be punched at the four corners of the connector body, and the spring and the protrusion can be used to implement it. There are many ways to implement the elastic buckle, such as directly forming two protrusions on the straight edge. Examples of such structures will not be given one by one in this case. In addition, in order to ensure the reliability of the connection, the connector in this case is realized by crossing the two adjacent holes. Of course, it can also be designed as a single-hole or three-hole connection.

[0043] In short, if a person of ordinary skill in the art is inspired by this case and, without departing from the inventive purpose of the utility model, designs a similar structure or embodiment to the technical solution without inventiveness, such design should fall within the scope of protection of the utility model. Any substitutions, improvements, etc. should also be included within the scope of protection of the utility model.
