[0036] The technical solutions according to the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings according to the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0037] An object of the present disclosure is to provide an assembled door frame. By improving the structure design thereof, the overall assembly accuracy of the door frame is not affected while the simple assembly and the convenient installation are ensured.

[0038] In order to make the above objects, features and advantages of the present disclosure more apparent, the present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments.

First Embodiment

[0039] As shown in FIGS. 1 to 6, the present embodiment provides an assembled door frame, the assembled door frame includes several side frames 1 spliced to each other; For the assembly of the corner parts of the door frame, two of the side frames 1 perpendicular to each other are spliced at their ends to form a right-angled side frame of the corner parts of the door frame. Further, every adjacent two of the side frames 1 for right-angle splicing are connected with each other via a corner connector assembly 2.

[0040] The corner connector assembly 2 is disposed inside the every adjacent two of the side frames 1 spliced at right angle. The corner connector assembly 2 includes a corner connector 21 and fixing bolts 22. One of the every adjacent two of side frames 1 spliced at right angle is fixed on the corner connector 21 by the fixing bolts 22.

[0041] As shown in FIGS. 3 and 4, the corner connector 21 is fixed inside a first side frame 11 which spliced at right angle with a second side frame, and the corner connector 21 can be designed as a block or a sheet structure. In order to facilitate the mounting and fixing of the corner connector 21 inside the first side frame 11, the shape thereof is the same as the cross-sectional shape of the first side frame 11. The corner connector 21 can be fixed by bonding, plugging, welding, and bolting, etc. And the corner connector 21 is provided with first bolt holes for connecting the fixing bolts 22. Second bolt holes are formed in the second side frame 12 corresponding to the first bolt holes, the second bolt hole matches the fixing bolts 22, the second bolt holes and the first bolt holes are coaxial. The length of the fixing bolts 22 is sufficient to connect the first bolt holes and the second bolt holes, countersunk bolts or pan head bolts can be used, and a Philips head or a slotted head can be selected according to practical requirements.

[0042] During splicing, each of the fixing bolts 22 is first screwed into the corresponding one of the second bolt holes to be connected to the second side frame 12, and then screwed into the corresponding one of the first bolt holes provided on the corner connector 21, so that the first side frame 11 is connected to the fixing bolts 22 together with the second side frame 12 through the corner connector 21, thereby the right-angle splicing of the first side frame 11 and the second side frame 12 is accomplished.

[0043] The side frames 1 are spliced directly together through the respective corner connector assemblies 2 each including the corner connector 21 and the fixing bolts 22. On one hand, the corner connector 21 and the fixing bolts 22 are each disposed within the corresponding side frame 1, such that the original external structure of the side frames 1 will not be changed after the side frames 1 are spliced together, thereby reducing assembly errors of the door frame caused by using the connecting structure. On the other hand, the direct splicing of the side frames 1 is achieved merely by two types of members that are the corner connector 21 and the fixing bolts 22. So, compared with the prior art, a welding process of the side frames is not required, the structure thereof is simple, and the mounting thereof is convenient.

[0044] Further, as shown in FIGS. 5 and 6, a bolt connection piece 23 is provided at a connection position between the second side frame 12 and the fixing bolts 22, the bolt connection piece 23 is recessed towards the inside of the second side frame 12, and the second bolt holes are provided on the bolt connection piece 23. The purpose of this structural design is to provide a recess on the second side frame 12 which is enough to accommodate the head of each of the fixing bolts 22, after each of the fixing bolts 22 is screwed into the corresponding one of the second bolt holes, the head of each of the fixing bolts 22 is received in the recess of the bolt connection piece 23. So that the outer contour of the second side frame 12 will not protrude at the connection position between the second side frame 12 and the fixing bolt 22 due to the additional installation of the fixing bolts 22, thereby, an original external structure of the side frames 1 is ensured, and assembly errors of the door frame is reduced.

[0045] Further, a seam decorative cover 3 is further arranged on a spliced seam between the first side frame 11 and the second side frame 12 spliced together at a right angle, so that on the basis of making the appearance more beautiful, the seam decorative cover 3 also achieves the effect of splicing and positioning the side frames 1.

[0046] Further, as shown in FIGS. 10 and 11, a groove 13 for receiving a sheet material is provided at an inner side of each of the side frames 1. A transom 4 is arranged between two of the side frames 1 which are parallel to each other. Two ends of the transom 4 are respectively connected to the corresponding two of side frames 1 by plugging, and transom 4 is provided with a bidirectional groove 41 having an H-shaped cross section, so as to enable the sheet material to plug into and fix with the bidirectional groove 41. The groove 13 on each of the side frames 1 and the bidirectional groove 41 of the transom 4 are respectively provided with an U-shaped adhesive strip 5 for fixing the sheet material.

[0047] Further, each of the side frames 1 is made of an iron profile, and the strength of the iron profile such as tensile strength, twisting resistance, and bending resistance is stronger than that of the aluminum profile. So, the iron profile with the same strength as the aluminum profile can have a thinner wall thickness, thereby reducing the weight and cost. Because the transom 4 has a relatively complex structure and is suitable for the production of an aluminum extrusion production process, so that the transom 4 is made of an aluminum profile for being easily machined.

Second Embodiment

[0048] The assembled door frame provided by the present embodiment differs from the first embodiment in that the structure design of the corner connector assembly 2 is different.

[0049] As shown in FIGS. 7 to 9, according to the present embodiment, the corner connector 21 of the corner connector assembly 2 is of a right-angle fixing structure, and two right-angle sides of the right-angle fixing piece structure are respectively provided with several bolt holes. Bolt holes corresponding to bolt holes provided on the corner connector 21 are also respectively provided on the first side frame 11 and the second side frame 12 which are spliced at right angle.

[0050] During splicing, the first side frame 11 and the second side frame 12 are respectively sleeved on the two right-angle sides of the corner connector 21, and the bolt holes provided on the first side frame 11 and the second side frame 12 are respectively aligned with the bolt holes provided on the corner connector 21. After that, the fixing bolts 21 are screwed into the bolt holes to fix the first side frame 11 and the second side frame 12 at the two right-angle sides of the corner connector 21 respectively to complete the splicing of the first side frame 11 and the second side frame 12.
