Description

A frame structure assembled with a backplane

technical field

The utility model relates to the field of assembly profiles, in particular to a frame assembly structure connected with a backboard.

Background technique

The existing frame is a regular-shaped product, and its backplane and profile frame mainly have the following assembly and sealing methods:

1. Assembly of back panel and profiles:

1. The backplane and the profile are formed by punching and stretching the whole sheet. This kind of integral molding of the backplane and the profile has good sealing performance, but the investment in equipment is large, and the structure and size are finalized at one time, with large limitations. It is not suitable to expand other sizes and A new model of the structure.

2. The backplane and the profile are two parts, and the backplane is assembled through the slot structure of the profile. In this way, there are gaps between the back plate and the profile, the sealing is not good, and water is easy to enter, which affects the product performance.

3. The back panel is assembled with the profiles by rivets. In this way, there are gaps between the back panel and the profiles, the sealing is not good, and water is easy to enter, which affects product performance. At the same time, the process is cumbersome, time-consuming, and increases labor costs.

Second, the sealing of the back plate and the profile:

1. The back plate and profile frame are sealed by rubber parts. Such as PVC rubber strips or EPDM rubber strips, this connection method is mainly fixed by rivets, the process is cumbersome, time-consuming, and increases labor costs.

2. The back panel and profile frame are sealed by glue coating. The actual operation of this method is complicated, difficult to clean, and affects the aesthetics. In addition, it takes a long time for the glue to cure, which is time-consuming and labor-intensive, which is not conducive to mass assembly line operations.

Chinese patent document CN 201527127U discloses an outer frame structure of an integral back plate type flat solar collector, including a designed integral back plate as the outer frame of the heat collector, and the frame opening is an “L”-shaped structure, which is a seal for the sealing strip. After installation with the glass cover plate, the convex surface of the frame mouth is facing downward to fix the upper and lower bead, and the upper and lower bead are used to fasten the outer frame of the collector and the glass cover plate. The utility model uses a convex lower bead and an upper bead to cooperate, and adds a sealing strip to provide a mosaic installation method, which solves the above problems, but this installation structure is still relatively cumbersome to assemble, and the structural strength after installation is insufficient The problem.

Utility model content

The purpose of the utility model is to provide a frame structure assembled with the backboard, the structure design is simpler, not only easy to install, but also has a high structural strength, especially suitable for assembly line production.

In order to achieve the above object, the utility model is realized through the following technical solutions:

A frame structure for assembly with a backboard, wherein an assembly edge protrudes from the edge of the frame installation surface, an extrusion edge is correspondingly arranged on the upper part of the assembly edge, and there is a space for accommodating the backplane between the assembly edge and the extrusion edge.

In particular, the extruded edge is a planar structure or a special-shaped structure.

In particular, grooves are provided on the assembly side; protruding structural ribs are provided on the pressing side corresponding to the grooves on the assembly side.

Preferably, the extruded side and the frame are connected by a smooth transition.

Further, the cross-sectional shapes of the grooves and raised structural ribs may be semicircular, triangular, rectangular, trapezoidal, or elliptical.

In order to further increase the sealing performance, a sealing member is provided between the assembly side and the extrusion side.

The material of the seal is rubber or polyurethane.

The beneficial effect of the utility model is that by using the press-fit assembly structure on the frame to complete the connection with the back plate, the production process is reduced, the rapid assembly of the product is realized, the production efficiency is improved, and the assembly of the back plate and the frame can be increased at the same time. The overall strength improves the performance of the product; in addition, the cooperation of the groove and the raised structural rib can play a sealing role, and the sealing performance of the product can be further enhanced by adding a seal between the back plate and the frame.
