Description

Technical Field

[0001] The utility model relates to the technical field of aluminum profiles, and particularly relates to a quickly splicable aluminum profile. Background Art

[0002] Aluminum profiles are widely used due to their light weight, easy plasticity, easy processing, etc., especially in the use of building materials, such as door frames, window frames, spliced exhibition booths, office desk frames, etc. A spliced exhibition booth means that aluminum profiles are quickly spliced into walls, and multiple walls enclose the exhibition booth. The existing splicing structure of aluminum profiles for spliced exhibition booths is relatively troublesome. When installing, two aluminum profiles need to be locked with screws. Tools are required for both installation and disassembly, and multiple people are needed to complete the work. There will be gaps in the splicing structure, which are prone to damage and loosening. Other components need to be used for locking at the corners, which is rather troublesome.

[0003] In order to solve the above problems, a patent document with the publication number of "CN204098692U" discloses a spliced aluminum profile, which relates to the field of aluminum profiles and includes an aluminum profile body and a splicing component. Circular grooves are vertically arranged on both side surfaces of the aluminum profile body. The splicing component includes a connecting plate and circular columns arranged on the vertical sides of the connecting plate. The diameter of the circular groove matches the diameter of the circular column for embedding and rotation. The opening width of the circular groove is smaller than the diameter of the circular groove. This splicing structure can rotate and is not easy to fall out. It can be directly applied at the corner without locking with other components. One person can complete the installation alone without using any tools. The structure is tightly stable. The setting of the cover plate is suitable for planar fixation, making the structure more stable. The lines are more beautiful in appearance, and the installation is convenient and the structure is stable.

[0004] In the above prior art, there is no limit at the end after the splicing component is inserted. Although the setting of the cover plate can enhance the stability of some structures, its limiting effect on the axial direction of the circular column of the splicing component is not good, making the splicing component easy to slide along the circular groove after splicing, resulting in an unstable structure after splicing. Seriously, it will even cause the splicing component to fall off and the structure to scatter. Therefore, a quickly splicable aluminum profile is needed. Summary of the Utility Model

[0005] The purpose of this application is to provide a quickly splicable aluminum profile to solve the problems raised in the above background art.

[0006] To achieve the above object, the present application provides the following technical solutions: A quick-assembling aluminum profile, including an aluminum profile body and a splicing member. One end of the aluminum profile body is provided with a circular connection hole, and a plurality of uniformly distributed positioning grooves are provided on the inner side wall of the circular connection hole. The splicing member includes a connecting plate and connecting cylinders. There are two connecting cylinders, which are integrally formed at both ends of the connecting plate respectively. On the side of the two connecting cylinders away from the connecting plate, positioning ridges are integrally formed. The connecting cylinders are inserted and matched with the circular connection hole, and the positioning ridges are inserted and matched with the positioning grooves;

When the swelling post is inserted into the swelling hole, the connecting cylinder generates a deformation of expanding outward, and the outer side wall of the connecting cylinder is in interference fit with the inner side wall of the circular connection hole.

[0009] Preferably, a resistance-increasing rib is fixed on the outer side wall of the connecting cylinder. When the swelling post is not inserted into the swelling hole, the outer side wall of the resistance-increasing rib is in clearance fit with the inner side wall of the circular connection hole. When the swelling post is inserted into the swelling hole, the resistance-increasing rib is in interference fit with the inner side wall of the circular connection hole.

[0010] Preferably, a cover plate groove with an inner diameter larger than that of the circular connection hole is provided on the upper surface of the aluminum profile body, and the positioning grooves are provided in the cover plate groove;

[0011] A cover is integrally formed at the upper end of the swelling post. After the swelling post is inserted into the swelling hole, the cover is movably embedded in the cover plate groove and closes the opening of the cover plate groove.

[0012] Preferably, a cover plate groove is also provided on the bottom surface of the aluminum profile body. The lower end of the swelling post is detachably connected with another cover through a connecting member, and the cover covers the cover plate groove on the bottom surface of the aluminum profile body.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment: Refer to Figures 1-4 A kind of aluminum profile that can be quickly spliced, which includes an aluminum profile body 1 and a splicing part 2. One end of the aluminum profile body 1 is provided with a circular connection hole 11, and a plurality of uniformly distributed positioning grooves 111 are arranged on the inner side wall of the circular connection hole 11. The splicing part 2 includes a connecting plate 21 and a connecting cylinder 22. There are two connecting cylinders 22, which are integrally formed at both ends of the connecting plate 21 respectively. On the side of the two connecting cylinders 22 away from the connecting plate 21, positioning ridges 23 are integrally formed. The connecting cylinder 22 is inserted and matched with the circular connection hole 11, and the positioning ridge 23 is inserted and matched with the positioning groove 111;

[0027] The connecting cylinder 22 is a circular ring column with a swelling hole 221 inside. On the side of the connecting cylinder 22 close to the connecting plate 21, a deformation notch 222 penetrating the connecting cylinder 22 is provided;

[0028] A swelling column 3 is inserted into the swelling hole 221. The diameter of the swelling column 3 is larger than the inner diameter of the swelling hole 221. When the swelling column 3 is inserted into the swelling hole 221, the connecting cylinder 22 generates a deformation of expanding outward, and the outer side wall of the connecting cylinder 22 is in interference fit with the inner side wall of the circular connection hole 11.

[0029] Based on the above structure, when the connecting cylinder 22 is inserted into the circular connection hole 11 to a predetermined position, only need to insert the swelling column 3 into the swelling hole 221, so that the connecting cylinder 22 generates a deformation of expanding outward, and the outer side wall of the connecting cylinder 22 is in interference fit with the inner side wall of the circular connection hole 11, so as to make the connection between the connecting cylinder 22 and the circular connection hole 11 closer, greatly enhancing the friction between the two, making a stable connection relationship between the connecting cylinder 22 and the aluminum profile body 1, avoiding the axial sliding of the connecting cylinder 22 along the circular connection hole 11, and thus avoiding the possibility of the deformation or scattering of the aluminum profile structure after splicing, and the actual use effect is excellent.

[0030] It should be noted that during the actual use process, through multiple tests, according to the thickness of the aluminum profile body 1 itself, the inner diameter of the circular connection hole 11, and the deformation coefficient of the connecting cylinder 22, the diameter of the swelling column 3 is set to be 0.5 - 5 mm larger than the inner diameter of the swelling hole 221, which can better meet the deformation requirements of different aluminum profiles;

[0031] Meanwhile, in order to facilitate the insertion of the expansion post 3 into the expansion post hole 221 of the connecting cylinder 22, a chamfer structure should also be provided at the lower end of the expansion post 3 (refer to Figure 2 , Figure 4 ), so as to facilitate the insertion of the expansion post 3 with a larger diameter into the expansion post hole 221 with a smaller inner diameter.

[0032] Furthermore, a resistance-increasing rib 24 is fixed on the outer side wall of the connecting cylinder 22. When the expansion post 3 is not inserted into the expansion post hole 221, there is a clearance fit between the outer side wall of the resistance-increasing rib 24 and the inner side wall of the circular connecting hole 11. When the expansion post 3 is inserted into the expansion post hole 221, the resistance-increasing rib 24 has an interference fit with the inner side wall of the circular connecting hole 11;

[0033] Through the setting of the resistance-increasing rib 24, an uneven connecting surface is formed between the outer side wall of the connecting cylinder 22 and the inner side wall of the circular connecting hole 11, so that the friction force between the connecting cylinder 22 and the inner side wall of the circular connecting hole 11 is further increased after deformation, which is beneficial to further improving the connection stability between the two and further enhancing the stability of the aluminum profile structure after splicing.

[0034] Furthermore, a cover plate groove 12 with an inner diameter larger than that of the circular connecting hole 11 is provided on the upper surface of the aluminum profile body 1, and the positioning groove 111 is arranged in the cover plate groove 12;

[0035] A cover 6 is integrally formed at the upper end of the expansion post 3. After the expansion post 3 is inserted into the expansion post hole 221, the cover 6 is movably embedded in the cover plate groove 12 and closes the opening of the cover plate groove 12;

[0036] Through the setting of the cover 6 and the cover plate groove 12, it is beneficial to cover the positioning groove 111 and the end face of the circular connecting hole 11 after inserting the expansion post 3, forming a relatively sealed structure. On the one hand, it can improve the aesthetics of the end face, and on the other hand, it can isolate the connecting end face from the outside world, avoiding the connecting end face from being polluted or eroded by the external environment (such as oxidation, rainwater corrosion, etc.), thereby improving the service life of the quickly spliceable aluminum profile to a certain extent after splicing.

[0037] Furthermore, a cover plate groove 12 is also provided on the bottom surface of the aluminum profile body 1. The lower end of the expansion post 3 is detachably connected with another cover 6 through a connecting piece, and the cover 6 covers the cover plate groove 12 on the bottom surface of the aluminum profile body 1;

[0038] An insertion hole 31 with an opening downward is provided at the lower end of the expansion post 3;

[0039] The connecting piece includes an insertion post 4. The lower end of the insertion post 4 is integrally formed with the cover 6, and the upper end of the insertion post 4 is inserted into the insertion hole 31;

[0040] Through the setting of the insertion post 4 and another cover 6, the other connecting end face of the aluminum profile body 1 can be covered, so as to play a more comprehensive protective role.

[0041] Furthermore, several rubber rings 5 are fixed inside the socket 31. The rubber rings 5 are in interference fit with the peripheral side wall of the plug post 4. Through the arrangement of the rubber rings 5, the connection stability between the plug post 4 and the expansion post 3 can be enhanced, thereby preventing the detachment of the other cover 6 and improving the use effect.

[0042] Working principle of the present utility model: During daily use, first insert the two connection cylinders 22 at both ends of the connection plate 21 into the two circular connection holes 11 of the two aluminum profile bodies 1 respectively, and make the positioning convex strips 23 be inserted and matched with the positioning grooves 111 inside the two circular connection holes 11 respectively to complete the preliminary installation of the two aluminum profile bodies 1. Then insert the expansion post 3 into the expansion post hole 221, causing the connection cylinder 22 to deform and expand outward, and making the outer side wall of the connection cylinder 22 be in interference fit with the inner side wall of the circular connection hole 11. In this way, the connection between the connection cylinder 22 and the circular connection hole 11 becomes tighter, greatly enhancing the friction between the two, resulting in a stable connection relationship between the connection cylinder 22 and the aluminum profile body 1, preventing the connection cylinder 22 from sliding axially along the circular connection hole 11, and thus avoiding the possibility of deformation or scattering of the aluminum profile structure after splicing, with excellent actual use effect. At the same time, after the cover 6 is inserted into the expansion post 3, it covers the positioning groove 111 and the end face of the circular connection hole 11, and cooperates with the cover plate groove 12 to form a relatively sealed structure. On the one hand, it can improve the aesthetics of the end face, and on the other hand, it can isolate the connection end face from the outside world, preventing the connection end face from being polluted or eroded by the external environment, thereby improving the service life of the quickly spliceable aluminum profile to a certain extent after splicing.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
