Description

Technical Field

[0001] The utility model relates to the technical field of profile splicing, in particular to a splicing structure of profiles. Background Art

[0002] Profiles refer to aluminum alloy profiles, which are widely used in the fields of architecture, chemical industry, etc.

[0003] When aluminum alloy profiles need to be spliced according to the installation requirements, external connectors such as hinges, aluminum alloy bearing parts serving as connection structures, bolts and other structures are used for fixation. However, this method is relatively inconvenient to operate. Although installation can be ensured by a simple snap-fit structure, generally the snap-fit structure on aluminum profiles has a small overall volume, resulting in insufficient overall firmness after splicing. And an overly large snap-fit structure will affect the strength of the aluminum profiles themselves. Therefore, there are certain limitations in actual use and there is room for improvement. Summary of the Invention

[0004] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a splicing structure of profiles, which has rapid splicing and good stability.

[0005] Technical solution of the utility model: A splicing structure of profiles includes Profile One, Profile Two and Profile Three. Both Profile One and Profile Three are connected to Profile Two. Profile One includes a profile main body One integrally provided and first connection parts and second connection parts symmetrically arranged on both sides of the profile main body One. A first installation shaft hole is provided on the profile main body One. The first connection part and the second connection part have the same structure, and both are provided with a notch with at least one side open. An extension block extends outward from the notch, and the outer side wall of the extension block protrudes from the outer side wall of the notch. A second installation shaft hole is provided on the extension block. Profile Two includes a profile main body Two. The center of the profile main body Two has a connection hole passage A penetrating through both ends. Both sides of the profile main body Two have concave first connection grooves. The first connection grooves are arranged along the length direction of the profile main body Two. A connection hole passage B penetrating through both sides is further provided on the profile main body Two. The connection hole passage B communicates with the first connection groove and vertically penetrates the central connection hole passage A. When Profile One and Profile Two are spliced, the extension block is inserted into the first connection groove, and a first connecting piece is inserted and fixed in the connection hole passage B and the second installation shaft hole. Both ends of Profile Two are provided with concave second connection grooves. The second connection grooves are arranged along the length direction of Profile Two. A connection hole passage C penetrating through both ends is provided on the profile main body Two. The connection hole passage C communicates with the first connection groove and vertically penetrates the central connection hole passage A. Profile Three includes a profile main body Three. The centers of both ends of the profile main body Three protrude with plug-in parts. The center of the plug-in part has a connection hole passage D. When Profile Three and Profile Two are connected, the plug-in part is inserted into the second connection groove, the connection hole passage D is aligned with the connection hole passage A, and a second connecting piece is inserted and fixed.

[0006] With the above technical solution, on the basis of not affecting the strength of the profile itself, the spliced part is enlarged, which can ensure the stability of installation while quickly splicing, avoid the phenomenon of shaking during subsequent use, and at the same time cooperate with the connecting piece to further improve the stability after the profiles are spliced. When the profiles are assembled with each other, the extension block of profile one is inserted into one of the first connection grooves of profile two, and the first connecting piece is inserted from the other first connection groove through the connection hole B and extends to the second installation shaft hole, so as to fix profile one and profile two. When profile three is connected to profile two, the insertion part is inserted into one of the second connection grooves of profile two, and the second connecting piece is inserted from the other second connection groove through the connection hole C and extends to the connection hole D, so as to fix profile three and profile two, completing the assembly of the profiles.

Insertion areas are formed between the opposite side walls of the two connection parts and the upper end surface of profile main body one. A plurality of insertion pieces extending downward are provided on the lower end surface of profile main body one. When two profile ones are spliced vertically, the insertion pieces are located in the insertion areas.

[0008] With the above further setting, the structure of the two profile ones is more compact after assembly, and the insertion pieces can also be inserted into other profiles. For example, when the insertion pieces face right, the adjacent profile is provided with insertion grooves adapted to the shapes of the insertion pieces, and the insertion pieces are inserted and screws are driven for fixation. When the insertion pieces face up, the profile is provided with convex blocks located in the insertion areas. The splicing methods are diverse and are not limited to being placed in one orientation. The side walls of the insertion areas are inclined, and the side walls of each insertion piece are also inclined. When two profiles are spliced, it is convenient for the insertion pieces to slide into the splicing areas, and the splicing is convenient and fast.

The connecting channel A is arranged along the length direction of the hollow cavity. First through holes are respectively opened on the bottoms of the two first connecting grooves. A first perforation is provided on the connecting channel A. The first perforation and the first through holes on the opposite sides communicate with each other in the hollow cavity to form the connecting channel B.

[0013] With the above further improvement, the second profile body is hollow, with low material cost, convenient for opening holes, and convenient for subsequent handling and assembly.

[0014] A further improvement of the present utility model: second through holes are respectively opened on the bottoms of the two second connecting grooves. A second perforation is provided on the connecting channel A. The second perforation and the second through holes on the opposite sides communicate with each other in the hollow cavity to form the connecting channel C. The connecting channel C and the connecting channel B are arranged in a staggered manner and are distributed in a "cross" shape.

[0015] With the above further improvement, the overall shape of the second profile body is rectangular, so that the force-bearing surface of the contact surface during erection is relatively large, which can improve the strength and stability of the profile; and the connecting grooves are arranged in four directions, which is convenient for connecting other profiles in four directions, enabling multi-directional connection; and the connecting channel B and the connecting channel C are also axially staggered, which can meet the requirement of simultaneously inserting screws for fastening connection without interference with each other.

When the connecting channel D312 on the third profile 31 is vertically communicated with the connecting channel A211 on the second profile 21, screws are inserted from bottom to top for fastening connection, thus completing the assembly of the profiles. And the screws pass through the upper and lower sides of the second profile 21 and penetrate into the center of the end of the third profile 31, which will make the profiles stress evenly and the overall structure firm. Two groups of the second profile 2 and the third profile 3 can be provided and are respectively located on both sides of the first profile 1.
