Description

Technical Field

[0001] The utility model relates to the technical field of PVC profiles, in particular to an assembled PVC profile. Background Art

[0002] CN202222517829.1 proposes an assembled PVC profile. By setting a fixed block and a connecting block, when the two profiles are ready to be docked, the connecting block is pulled out, and then the rotating plate in the placement groove is pulled out and clamped with the limit block. In this way, the connecting block will not move under the restriction of the fixed block and the limit block. Then another profile is inserted into the connecting block through the fixed block fixed at the upper end of the inner wall. In this way, the two profiles can be docked and assembled, and then the connection of the profiles can be bonded. In this way, the connection gap is smaller and will not be skewed during bonding.

[0003] Although the above-mentioned prior art solves the problem of skewness when two profiles are butted, assembled and pasted, in some cases the profiles need to be cut, or they may be assembled with other profiles to form the required length after cutting. At this time, after the assembled PVC profiles in the comparative documents are cut, the active structures such as the shift blocks and rotating plates inside them will be cut off, making the device unable to be used normally, and there are limitations on its use. Utility Model Content

[0039] The first PVC profile body 1 and the second PVC profile body 6 have the same structure;

[0040] The first PVC profile body 1 and the second PVC profile body 6 are both slidably fitted with a PVC profile core 2;

[0041] The inner wall of the PVC profile core 2 is fixedly equipped with a splicing connection structure 3 along the length direction;

[0042] The ends of the first PVC profile body 1 and the second PVC profile body 6 are fitted together;

[0055] In some embodiments, in order to further improve the firmness of the end surface adhesion between the first PVC profile body 1 and the second PVC profile body 6, a first annular mesh plate 8 is inserted and fixed in the outer annular groove 7, and the adhesive layer filled between the first PVC profile body 1 and the second PVC profile body 6 enters the mesh of the first annular mesh plate 8, and after the adhesive solidifies, it is connected to the first annular mesh plate 8 as a whole.

[0056] In some embodiments, in order to improve the firmness of the adhesion between the end faces of the first PVC profile body 1 and the second PVC profile body 6, an inner annular groove 9 is provided on the inner annular surface of the end faces of the first PVC profile body 1 and the second PVC profile body 6. The adhesive layer filled between the first PVC profile body 1 and the second PVC profile body 6 enters the inner annular groove 9, further increasing the contact area between the end faces of the first PVC profile body 1 and the second PVC profile body 6 and the adhesive.

[0057] In some embodiments, in order to further improve the firmness of the end surface adhesion between the first PVC profile body 1 and the second PVC profile body 6, a second annular mesh plate 10 is inserted and fixed in the inner annular groove 9, and the adhesive layer filled between the first PVC profile body 1 and the second PVC profile body 6 enters the mesh of the second annular mesh plate 10, and after the adhesive solidifies, it is connected to the second annular mesh plate 10 as a whole.
