Description

Technical Field

[0001] This utility model relates to the field of decorative panel technology, and more specifically, to a connection structure. Background Technology

[0002] Decorative panel connection structures are a key technology in the field of architectural decoration, especially in prefabricated buildings and interior and exterior decoration projects, where the requirements for the convenience, stability, and aesthetics of the connection structure are increasing. In existing technologies, the slot and hook connection method is widely used due to its convenient installation and high detachability; however, in practical applications, it still suffers from problems such as insufficient connection stability, weak deformation resistance, and lack of multi-directional limiting.

[0003] Existing patents present various forms of engagement between the slot and the hook, but they generally suffer from the following drawbacks:

[0004] 1. Chinese Patent (Application No.: CN202321498097.4) discloses a snap-on aluminum alloy profile, which achieves connection by inserting a T-shaped sub-component into the groove of the T-shaped profile. However, the insertion alignment depends on the precision of manual insertion, and it is easy to have problems such as looseness and wobbling after insertion or difficulty in insertion when it is too tight due to processing tolerance.

[0005] 2. Chinese Patent (Application No.: CN202121799846.8) discloses a buckle structure that uses an inverted buckle to cooperate with a U-shaped buckle and achieves self-locking through a spring. However, after long-term use, the inverted buckle is prone to springback failure due to material fatigue. Utility Model Content

[0006] Based on this, in order to solve the problems of traditional snap-fit ​​structures: 1. troublesome installation, with insertion alignment relying on manual precision; 2. prone to looseness and wobbling after insertion due to machining tolerances, or difficult insertion when too tight; 3. prone to failure due to material fatigue and springback after long-term use, this utility model provides a connection structure, the specific technical solution of which is as follows:

[0007] A connection structure, including

[0008] A card slot, wherein a first engaging part and an abutting part are provided in the card slot, and the card slot is used to connect with a first block to be connected;

[0009] The hook has a second engaging portion that matches the first engaging portion. When the hook rotates and engages in the slot, the first engaging portion abuts against the second engaging portion, and the hook abuts against the engaging portion. The hook is used to connect with the second block to be connected.

[0010] The aforementioned connection structure, when the hook rotates and engages with the slot, creates a limiting effect between the first and second engaging parts; simultaneously, the hook and the abutment part physically abut against each other, forming the main engagement point; through the abutment between the first and second engaging parts, and the abutment between the hook and the abutment part, bidirectional limiting is achieved; the abutment part inside the slot can compensate for engagement gaps caused by dimensional errors or installation deviations of the decorative panel, avoiding connection failures due to insufficient processing precision; the hook's rotation engagement path is designed with an arc trajectory, reducing the difficulty of manual alignment, while the abutment part provides tactile feedback for proper installation; the engagement between the slot and the hook achieves the connection between the first and second blocks to be connected. This connection structure solves the problems of traditional engagement structures: 1. cumbersome installation, with insertion alignment relying on manual precision; 2. easy to become too loose and wobble after insertion due to processing tolerances, or difficult to insert when too tight; 3. easy to fail due to material fatigue and springback failure after long-term use; and it can achieve a fixed connection without the use of bolts, improving installation efficiency.

[0011] Furthermore, the slot includes a first connecting part, a second connecting part, and a third connecting part connected in sequence; a snap-fit ​​space is formed between the first connecting part, the second connecting part, and the third connecting part, and the hook snaps into the snap-fit ​​space.

[0012] Furthermore, the first snap-fit ​​portion is disposed on the first connecting portion, and the abutting portion is disposed on the third connecting portion.

[0013] Furthermore, the hook includes a fourth connecting part, a fifth connecting part, and a sixth connecting part connected in sequence; when the slot engages with the hook, the fourth connecting part abuts against the abutting part and the third connecting part respectively.

[0014] Furthermore, the third connecting portion is also provided with a first protrusion, and the sixth connecting portion is also provided with a second protrusion; the connecting structure also includes a reinforcing block, which is disposed in the snap-fit ​​space, one side of the reinforcing block abuts against the sixth connecting portion, the other side of the reinforcing block abuts against the third connecting portion, and one end face of the reinforcing block abuts against the abutting portion; the first protrusion and the second protrusion cooperate to prevent the reinforcing block from disengaging from the snap-fit ​​space.

[0015] Furthermore, the reinforcing block is provided with a screw portion, which passes through the second connecting portion and the fifth connecting portion, and the screw portion is threadedly connected to the second connecting portion and the fifth connecting portion.

[0016] Furthermore, the outer contours of both the first and second latching portions are arc-shaped.

[0017] Furthermore, the outer contours of both the first and second snap-fit ​​portions are flat. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with its embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit its scope of protection.

[0038] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0040] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0041] like Figure 1-16As shown, a connection structure in one embodiment of the present invention includes a slot 1 and a hook 2; the slot 1 is provided with a first engaging part 3 and an abutting part 4, and the slot 1 is used to connect with a first block 31 to be connected; the hook 2 is provided with a second engaging part 5 that matches the first engaging part 3, and when the hook 2 rotates and engages in the slot 1, the first engaging part 3 abuts against the second engaging part 5, and the hook 2 abuts against the abutting part 4; the hook 2 is used to connect with a second block 32 to be connected.

[0042] The above-mentioned connection structure, when the hook 2 is rotated and inserted into the slot 1, the first engaging part 3 and the second engaging part 5 form a limiting position, and at the same time the hook 2 and the abutting part 4 physically abut against each other, forming the main engaging point; through the abutting of the first engaging part 3 and the second engaging part 5, and the abutting of the hook 2 and the abutting part 4, a two-way limiting is achieved; the abutting part 4 is provided in the slot 1, which can compensate for the engaging gap caused by the size error of the decorative panel or the installation deviation, and avoid connection failure caused by insufficient processing accuracy; the path of the hook 2 rotating and engaging is designed as an arc trajectory, which reduces the difficulty of manual alignment, and at the same time the abutting part 4 provides tactile feedback for installation in place; through the engaging of the slot 1 and the hook 2, the connection between the first block to be connected 31 and the second block to be connected 32 is achieved. This connection structure solves the problems of traditional snap-fit ​​structures: 1. troublesome installation, with insertion and alignment relying on manual precision; 2. prone to looseness and wobbling after insertion due to machining tolerances, or difficult to insert when too tight; 3. prone to failure due to material fatigue and springback after long-term use. It also enables a fixed connection without the use of bolts, improving installation efficiency.

[0043] like Figure 1-4 As shown, in one embodiment, the slot 1 includes a first connecting part 11, a second connecting part 12, and a third connecting part 13 connected in sequence; a snap-fit ​​space 6 is formed between the first connecting part 11, the second connecting part 12, and the third connecting part 13, and the hook 2 snaps into the snap-fit ​​space 6; the first snap-fit ​​part 3 is disposed on the first connecting part 11, and the abutting part 4 is disposed on the third connecting part 13; the hook 2 includes a fourth connecting part 21, a fifth connecting part 22, and a sixth connecting part 23 connected in sequence; when the slot 1 and the hook 2 snap into each other, the fourth connecting part 21 abuts against the abutting part 4 and the third connecting part 13 respectively. Thus, when the latch is engaged, the fourth connecting part 21 simultaneously contacts the third connecting part 13 (side wall of the slot 1) and the abutting part 4, forming a double abutting action in both the lateral and longitudinal directions; the first latching part 3 (first connecting part 11) and the second latching part 5 (hook 2) form a limiting point, and the abutting part 4 (third connecting part 13) and the fourth connecting part 21 form a main latching point, constituting a "primary-secondary" limiting hierarchy; the three-section connecting part of the slot 1 forms a progressive latching space 6, and when the hook 2 is inserted, the "guiding first, locking later" action is achieved through the abutting action of the fourth connecting part 21 and the third connecting part 13.

[0044] like Figure 1-5 As shown, in one embodiment, the third connecting portion 13 is further provided with a first protrusion 7, and the sixth connecting portion 23 is further provided with a second protrusion 8; the connecting structure also includes a reinforcing block 9, which is disposed in the snap-fit ​​space 6, one side of the reinforcing block 9 abuts against the sixth connecting portion 23, the other side of the reinforcing block 9 abuts against the third connecting portion 13, and one end face of the reinforcing block 9 abuts against the abutting portion 4; the first protrusion 7 and the second protrusion 8 cooperate to prevent the reinforcing block 9 from disengaging from the snap-fit ​​space 6. Thus, the abutment part 4, the first protrusion 7 of the third connecting part 13, and the second protrusion 8 of the sixth connecting part 23 form an interlocking mechanism, while the reinforcing block 9 is confined within the interlocking space 6 between the three, forming a three-dimensional limiting structure of "protrusion + abutment part 4". Even if the decorative panel is subjected to vertical tension (such as the suction force of the curtain wall), the mechanical interlock between the protrusion and the reinforcing block 9 can prevent the hook 2 from coming out of the slot 1. The external load is transmitted to the reinforcing block 9 through the hook 2, and then distributed by the reinforcing block 9 to the first protrusion 7 of the third connecting part 13 and the side wall of the slot 1, forming a triangular force transmission path of "hook 2 → reinforcing block 9 → slot 1", thereby strengthening the connection strength of the connection structure.

[0045] like Figure 1-5 As shown, in one embodiment, the reinforcing block 9 is provided with a screw portion 10, which passes through the second connecting portion 12 and the fifth connecting portion 22, and is threadedly connected to both the second connecting portion 12 and the fifth connecting portion 22. Thus, this connection structure can also strengthen and reinforce the connection between the slot 1 and the hook 2 through the screw portion 10, further preventing the hook 2 from detaching from the slot 1.

[0046] like Figure 1-5 As shown, in one embodiment, the outer contours of both the first snap-fit ​​portion 3 and the second snap-fit ​​portion 5 are arc-shaped.

[0047] like Figure 1-5 As shown, in one embodiment, the outer contours of both the first snap-fit ​​portion 3 and the second snap-fit ​​portion 5 are flat.

[0048] In one embodiment, the outer contours of both the first snap-fit ​​portion 3 and the second snap-fit ​​portion 5 are serrated.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
