Description

A reliable profile connection structure

technical field

The invention relates to a connection structure of profiles in the field of profiles.

Background technique

In order to achieve the required profile shape, many profiles are formed by connecting profile units, such as double-color glue injection profiles or spliced profiles. However, for combined profiles, it is often difficult to resist torsion and easy to loosen between its profile units, so most of the existing designs use the connection structure of double-sided hooks. Referring to Figure 1, the connection structure of the double-sided hooks includes a left profile unit 1a and a right profile unit 2a, the right profile unit 2a protrudes two right connecting hooks 21a up and down to the left, and the left profile unit 1a protrudes two pairs of connecting groups to the right , are respectively connected with two right connecting hooks 21a, specifically, each pair of connecting groups includes an abutting plate 11a on the outside that abuts against the outer side of the corresponding right connecting hook and an inner one that is in contact with the corresponding right connecting hook connected left connecting hook 12a. The upper and lower connectomes are mirror images of each other. In this way, whether it is twisted to the left or to the right, due to the relationship between hooking and abutment in the structure, the left profile unit 1a and the right profile unit 2a are not easy to loosen each other, so this double-sided hook The connection structure is indeed relatively stable. But this connection structure has an obvious defect: in order to resist the left and right torque, it has to make two pairs of connection groups (if one is missing, the reverse torque can easily loosen the hook joint, and the abutment plate is not at all can not be blocked), and the upper and lower connecting groups cooperate with the upper and lower right connecting hooks, naturally forming a cavity 3a when combined, the cavity 3a is bulky and takes up space, making it difficult for engineers to design a portable combination Profiles, for example, only need to provide a combination of "I" type profiles in actual work, but if designed according to the double-sided hook connection structure, "II" type will eventually be produced. And to form a double-sided hook connection structure, it is necessary to apply force to the panels of the left profile unit 1a and the right profile unit 2a, which will easily cause deformation of the panels.

Contents of the invention

The technical problem to be solved by the present invention is to provide a reliable profile connection structure, which enables the combination of profile units to occupy a small space without the traditional large cavity, and has strong torsion resistance and is not easy to loose .

The solution that the present invention solves its technical problem is:

A reliable profile connection structure, including a first profile unit and a second profile unit, the first profile unit includes: a first embedding pit, the left pit wall is the left side plate, and the right pit wall is the center column; Two embedding pits, the left pit wall is the center column, and the right pit wall is the right side plate body or right side plate assembly; the second profile unit includes: the center column accommodation pit, the left pit wall is the end The first connecting hook is fixed in the first embedding pit, the right pit wall is the second connecting hook whose end is fixed in the second embedding pit, and the end of the central column is located in the accommodating pit of the central column; the first The embedding pit, the center column accommodating pit, and the second embedding pit are arranged in order from left to right.

It should be pointed out that the concepts of left, right and other orientations mentioned in this article are only descriptions of relative positions between components, and do not represent an absolute spatial position relationship.

From the technical solution of the present invention, it can be seen that the central column not only serves as the right pit wall of the first scarfing pit, but also serves as the left pit wall of the second scarring pit, which creates a huge problem for the prior art. The difference is that since the central column plays the same role as the two walls, the structure of the present invention no longer has a large-span cavity, which greatly saves space and improves the flexibility of position design, and there will be no bending when combining profiles Profile panel phenomenon. In addition, the right pit wall of the second embedding pit can be a single profile, or a combination of structures, for example, the right side plate body is such a structure: it is the right end of the first profile unit , the end of the right plate body is against the second profile unit or embraces the end of the second connecting hook. Alternatively, the right side plate assembly has such a structure: it includes two parts, one part is a turning hook on the right section of the first profile unit, and the other part is a top connecting step of the second profile unit, the turning The folding hook is closely against the abutting step.

In order to make the profile connection structure more reliable, the three pits can be injected with glue, so that the connecting hook and the center column can be hooked together. In fact, by controlling the amount of glue injection and the length and time of splicing, the glue injection and fixing of the plates in the three pits can be completed at one time. For example, glue is only injected in the center column accommodation pit, and the glue in the pit will naturally overflow into the first and second scarfing pits next door when the profile is crimped, and the center column and the connecting hooks on both sides are fixed when it is finally cured.

The beneficial effects of the present invention are: It can be seen from the above technical solution that in the connection structure of the present invention, the first embedding pit, the center column accommodating pit, and the second embedding pit are arranged in sequence from left to right, and the center post At the same time, as the pit walls on both sides, there is no longer a wide cavity in the whole connection structure. In the original bilateral hook connection structure, a pair of hooks need to be installed on both sides to add glue, but the center column is actually a single hook with both sides facing inward. The function is integrated into itself, so that when the profiles are assembled, the panels will no longer be easily bent, and a wider design space will be freed up for engineers to design other profile functional structures. When twisting both sides of the profile in the present invention, since the center column is inserted into the center column accommodation pit, and there are left side plate, right side plate/right side plate clamped and wrapped on both sides, the space for shaking is already very small. The trend of twisting and loosening is forced to be transformed into the trend of pulling out the two connecting hooks from the scarfing pit, but the ends of the two connecting hooks are respectively fixed and extremely difficult to pull out, so it is almost only possible to force the first connecting hook or the second connecting hook The root of the second connecting hook is broken (this is determined by the profile material, thickness and other factors, and it is an objective problem that cannot be overcome by clever connection structure design, but the problem of the mutual loosening of the profile units can be overcome by optimizing the connection structure) , but it is difficult for the profile units to loosen from each other, which truly realizes the firm connection of the small-volume composite profile units. The invention has ingenious structure, safety and stability, quick assembly and can be widely used in the connection structure of profile units.

The idea, specific structure and technical effects of the present invention will be clearly and completely described below in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features and effects of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts belong to The protection scope of the present invention. In addition, all the connection/connection relationships mentioned in this article do not refer to the direct connection of components, but mean that a better connection structure can be formed by adding or reducing connection accessories according to specific implementation conditions. The various technical features in the invention can be combined interactively on the premise of not conflicting with each other.

Embodiment 1: Referring to Figure 2, a reliable profile connection structure includes a first profile unit 1 and a second profile unit 2, the first profile unit 1 includes: a first embedding pit, the left pit wall is the left The side plate 21, the right pit wall is the center column 22; the second embedding pit, the left pit wall is the center column 22, the right pit wall is the right side plate body 23 or the right side plate assembly 24; the second The profile unit 2 includes: a central pillar accommodation pit, the left pit wall is the first connecting hook 11 whose end is fixed in the first embedding pit, and the right pit wall is the second connecting hook whose end is fixed in the second embedding pit 12. The end of the center pillar 22 is located in the center pillar accommodation pit; the first embedding pit, center pillar accommodation pit, and second embedding pit are arranged in sequence from left to right.

Then, in the present embodiment, the right wall of the second embedding pit adopts the right side plate assembly 24, that is, the part framed by the dotted line in Fig. 2, which has such a structure: it includes two parts, one part is the first profile unit 1 A turning hook on the right section, and the other part is an abutting step of the second profile unit 2, and the turning hook closely abuts against the abutting step.

The central column accommodation pit is provided with a middle injection colloid wrapping the end of the central column 22 . In the first embedding pit and in the second embedding pit, there are respectively provided side injection glues wrapping the end of the first connecting hook 11 and the end of the second connecting hook 12 respectively. Here, the above-mentioned intermediate pit can be used for one-time injection of glue, and when it is not cured, press and squeeze the glue to overflow and wrap the ends of the first and second connecting hooks on both sides, that is, the middle injection glue and The side injection colloid is the same whole. In order to strengthen the firmness of the structure again, the first connecting hook 11 is hooked with the central column 22 , and the second connecting hook 12 is also hooked with the central column 22 . In this way, the connecting hooks on both sides can no longer be easily pulled out from their respective embedding pits.

As can be seen from Fig. 2, a large area of design space has been vacated on the left and upper sides of the left side panel 21 and the right side and upper side of the right side panel assembly 24, so the left side of the left side panel 21 continues to extend to the left to form a flat panel 1. The right side of the right side plate assembly 24 also continues to extend to the right to form a flat plate, and the two form a flat-top combined profile.

Embodiment 2: Referring to Fig. 3, the structure of Embodiment 2 is basically the same as that of Embodiment 1, except that after the design space is vacated on the left side and above the left side panel 21, the left side panel 21 continues to extend upwards to make the overall appearance A state of "T" shape placed horizontally.

Embodiment 3: Referring to Fig. 4, the structure of embodiment 3 is basically the same as that of embodiment 1, but the right pit wall of the second embedding pit is the right side plate body 23, and the right side plate body 23 has such a structure: It is the protruding part of the right end of the first profile unit 1 , and the end of the right plate body 23 abuts against the second profile unit 2 or wraps around the end of the second connecting hook 12 . More specifically, in this embodiment, the end of the right plate body 23 abuts against the second profile unit 2 . In this way, the second profile unit 2 is more difficult to overturn. The left side of the left side plate 21 continues to extend leftwards to become a flat plate, and the right side of the right side plate body 23 also continues to extend rightwards to form a flat plate, and the two form a flat-top composite profile.

Embodiment 4: Referring to FIG. 5 , the structure of embodiment 4 is basically the same as that of embodiment 3, but the left side plate 21 continues to extend upward.

Embodiment 5: Referring to Fig. 6, the structure of embodiment 5 is basically the same as that of embodiment 4, except that the column 22 is slightly short and does not completely withstand the bottom wall of the middle column accommodation pit, while the left side plate 21 faces The left side continues to extend to the left to form a flat plate, and the right side of the right plate body 23 also continues to extend to the right to form a flat plate, and the two form a flat-top composite profile. As for the middle injection glue and the side injection glue, you can inject glue according to the actual situation, as long as the center column and the two connecting hooks can be fixed firmly.

Embodiment 6: Referring to FIG. 7 , the structure of embodiment 6 is basically the same as that of embodiment 5, and also adopts the design of a short center column, but the top of the left side plate 21 is flush with the upper plane of the second profile unit 2 .

Embodiment 7: Referring to FIG. 8, the structure of Embodiment 7 is basically the same as that of Embodiment 4, but the end of the right side plate body 23 is not against the second profile unit 2 but embraces the end of the second connecting hook 12 . This structure also follows the basic idea of the present invention. In order to ensure that the second profile unit 2 is not easy to twist to the right, the end of the right plate body 23 wraps around the end of the second connecting hook 12 and the second embedding pit formed after the end of the second connecting hook 12 should be Filled with strong colloid.

Referring to FIG. 9, this is an example of a practical application of the present invention. Figure 9 shows a two-color combination profile, which is H-shaped overall, with one profile unit on the left and another profile unit on the right. When assembling, simply insert the first connecting hook 11 and the second connecting hook 12 Go into the corresponding embedding pit, hook it with the center column 22 at the same time, inject glue into the corresponding embedding pit and the center column accommodating pit and solidify.
