Description

Technical Field

[0001] This utility model relates to the field of bracket locking technology, specifically a lightweight locking structure. Background Technology

[0002] In architectural decoration, exhibition setup, and other fields, light steel scaffolding is widely used for the construction of ceilings, partitions, and other structures. To facilitate the installation of lighting fixtures, pipelines, and other components on the scaffolding, a lightweight locking system composed of plastic parts and metal blocks is commonly used in the market. In existing technology, the plastic parts of this type of locking system are typically designed to wrap around the metal blocks from both sides. During installation, the elastic deformation of the plastic parts allows them to be directly pressed and snapped onto the edge of the scaffolding.

[0003] However, this structure has significant drawbacks: First, the sliding adjustment of the latch on the bracket relies on the friction between the plastic part and the bracket surface. Because the plastic part directly abuts against the bracket, the friction is considerable, resulting in poor sliding and difficulty in easy adjustment. Second, this structure has strict requirements on the manufacturing tolerances of the bracket and the dimensional accuracy of the latch itself. Its locking force mainly depends on the thickness of the plastic part. If the bracket opening is slightly small, the latch is difficult to press and install; if the bracket opening is slightly large, the latch may not lock properly and may easily loosen.

[0004] Therefore, it is essential to design a lightweight locking structure that is highly practical and has a smooth sliding adaptability. Utility Model Content

[0005] The purpose of this invention is to provide a lightweight locking structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lightweight locking structure, including an upper clamping member with a connecting part at its bottom; a lower clamping member with a locking part that cooperates with the connecting part; the lower clamping member also has an installation structure for installing external mounting components.

[0007] According to the above technical solution, the connecting part includes at least one elastic buckle disposed at the bottom of the upper clamping member, and the locking part includes a slot adapted to the elastic buckle; when the elastic buckle is pressed into the slot, the upper clamping member and the lower clamping member are relatively fixed.

[0008] According to the above technical solution, the end of the elastic buckle is provided with a hook. When the elastic buckle is inserted into the slot, the hook abuts against the bottom surface of the lower clamping member.

[0009] According to the above technical solution, there are two elastic buckles, which are arranged symmetrically.

[0010] According to the above technical solution, the mounting structure is a threaded hole located in the middle of the lower clamping member.

[0011] According to the above technical solution, the upper clamping member has a first through hole in the middle.

[0012] According to the above technical solution, the upper clamping member is made of plastic, the lower clamping member is made of metal, and the maximum lateral dimension of the lower clamping member is greater than the width of the bracket mounting opening.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are: (1) By setting up a combination of elastic buckles and slots, the upper and lower clamping parts can be quickly pre-assembled without any tools. The "click" sound provides clear feedback that the assembly is in place, which simplifies the process and greatly improves the installation efficiency. (2) By setting a rotational anti-detachment mechanism, the lower clamping part is larger than the bracket opening to form a mechanical limit, which fundamentally prevents the lock from accidentally falling off the bracket. At the same time, before locking, the lock can slide easily on the bracket, realizing smooth position fine adjustment; the rotational anti-detachment structure has extremely low requirements for the manufacturing tolerance and dimensional accuracy of the bracket itself. As long as the lock can be smoothly inserted and rotated, reliable anti-detachment can be achieved, which significantly enhances the product's adaptability to brackets of different specifications, reduces construction difficulty and material pickiness; (3) By providing threaded holes, which are used for final locking and also serve as a standard interface for connecting external components, the integration and expansion of functions are realized.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 The present invention provides a technical solution: a lightweight locking structure, including an upper clamping member 1 with a connecting part at its bottom; a lower clamping member 2 with a locking part that cooperates with the connecting part; the lower clamping member 2 also has an installation structure for installing external components.

[0017] Specifically, during assembly, the operator manipulates the connecting and locking parts to quickly fix the upper clamping part 1 and the lower clamping part 2. After assembly, a specific spatial relationship is naturally formed between the upper clamping part 1 and the lower clamping part 2. Because the upper clamping part 1 is made of plastic, it can be easily fitted together or separated from the lower clamping part 2. The plastic part of the upper clamping part 1 is fixed in the middle, while the two sides can still be separated. This structure is designed to clamp onto the curved edge of the bracket. After the latch is installed on the bracket, it is tightened with bolts, forming the mounting structure. After installation, the bolts and the threads of the mounting structure engage, allowing the bolts to tighten the two clamping parts, thus securing them tightly against the bracket. Simultaneously, external components can be installed and fixed using the mounting structure on the lower clamping part 2.

[0018] When installing the latch, first align it vertically with the opening of the bracket, that is, the gap between the upper clamp 1 and the lower clamp 2 to accommodate the curved edge of the bracket. After inserting it, rotate the latch, and the latch changes from vertical to horizontal. In this way, the lower clamp 2 changes from vertical to horizontal, and the horizontal length is longer. In this way, the lower clamp 2 can well support the curved edge of the bracket from below and will not fall off. Overall, there are not many restrictions on the size of the bracket. As long as the latch can rotate horizontally, it can be implemented.

[0019] By adopting a split structure in which the upper clamping part 1 and the lower clamping part 2 are combined by a connecting part and a locking part, the latch achieves modular assembly and is easy to operate.

[0020] The connecting part includes at least one elastic buckle 11 located at the bottom of the upper clamping member 1, and the locking part includes a slot 21 adapted to the elastic buckle 11; when the elastic buckle 11 is pressed into the slot 21, the upper clamping member 1 and the lower clamping member 2 are fixed relative to each other.

[0021] Specifically, the connecting portion at the bottom of the upper clamping member 1 is embodied in at least one elastic buckle 11. Correspondingly, the locking portion on the lower clamping member 2 is embodied in a slot 21 that is adapted in shape and position to the elastic buckle 11.

[0022] During assembly, the elastic buckle 11 is aligned with the slot 21 and pressure is applied. Under pressure, the elastic buckle 11 undergoes elastic deformation, allowing it to smoothly enter the slot 21. Once in place, the elastic buckle 11's elastic restoring force ensures a tight fit with the inner wall of the slot 21, thus achieving relative fixation between the upper clamping member 1 and the lower clamping member 2. This "elastic buckle-slot" mating structure enables quick, tool-free, one-click assembly, significantly simplifying the installation process and improving assembly efficiency.

[0023] The end of the elastic buckle 11 is provided with a hook 12. When the elastic buckle 11 is inserted into the slot 21, the hook 12 abuts against the bottom surface of the lower clamping member 2.

[0024] Specifically, the end of the elastic buckle 11 is further provided with a hook 12. When the elastic buckle 11 is engaged in the groove 21 of the lower clamping member 2 under pressure and reaches the predetermined position, the hook 12 will cross the edge of the groove 21 and rebound outward under the action of elastic restoring force, so that its hook-shaped part abuts against the bottom surface of the lower clamping member 2. By setting the hook 12, reliable axial locking between the upper and lower clamping members is achieved, preventing accidental loosening during use and improving the connection stability and long-term safety and reliability of the structure.

[0025] There are two elastic buckles 11, which are arranged symmetrically.

[0026] Specifically, the two elastic latches 11 at the bottom of the upper clamp 1 are arranged symmetrically. This symmetrical structure ensures that the axes of the two elastic latches 11 are parallel to each other, resulting in even force distribution during installation and smoother operation.

[0027] The mounting structure is a threaded hole located in the middle of the lower clamping member 2.

[0028] Specifically, the threaded hole penetrates the body of the lower clamping member 2, and its inner wall is machined with continuous standard threads for mating with the external threads of external components (bolts, screws, etc.). This structure allows for the connection of various external components using conventional threaded fasteners, achieving both a stable and reliable connection and convenient disassembly.

[0029] The upper clamping member 1 has a first through hole 13 in the middle.

[0030] Specifically, the existence of the first through hole 13 facilitates the installation of accessories and allows bolts to pass through for fixing.

[0031] The upper clamp 1 is made of plastic, and the lower clamp 2 is made of metal. The maximum lateral dimension of the lower clamp 2 is greater than the width of the bracket mounting opening.

[0032] Specifically, by employing a composite material design of plastic and metal, an optimized allocation of function and performance is achieved. The upper clamping component 1, made of plastic, possesses good elasticity, facilitating elastic clamping and snap-fit ​​connection with the bracket; the lower clamping component 2, made of metal, provides higher structural strength and wear resistance, ensuring the reliability and durability of the threaded connection. The mechanical limit created by the lower clamping component 2's lateral dimension being larger than the bracket opening fundamentally prevents the latch from accidentally detaching from the bracket. As long as the latch can be smoothly inserted and rotated, reliable anti-detachment is achieved, significantly enhancing the product's adaptability to brackets of different specifications, reducing construction difficulty and material requirements.

[0033] Working Principle: Step 1: Quick Pre-assembly. Place the lower metal clamp 2 below, with its central threaded hole facing upwards. Align the two symmetrical elastic clips 11 at the bottom of the upper plastic clamp 1 with the slots 21 on the lower clamp 2. Apply vertical pressure to deform the elastic clips 11 and engage them in the slots 21 until the hooks 12 at their ends cross the edge of the slots 21 and spring back, locking against the bottom surface of the lower clamp 2. A "click" sound will be heard, indicating that the locking mechanism has been pre-assembled into a stable unit.

[0034] Step 2: Mounting the bracket and rotating to prevent detachment. Align the pre-assembled locking assembly with its shorter vertical section against the opening of the bracket, allowing the bent edge of the bracket to fit into the clamping gap between the upper and lower clamping parts, then slide it in. After insertion, rotate the entire locking assembly 90°, changing it from vertical to horizontal. At this point, the lower clamping part 2, because its horizontal length is greater than the bracket opening, forms a mechanical limit below the bracket, reliably preventing the entire locking assembly from detaching from the bracket.

[0035] In this state, the latch slides very easily and smoothly on the bracket, allowing users to make precise, stepless position adjustments. This design has low requirements for the dimensional tolerances of the bracket; as long as the latch can rotate smoothly, the anti-slip function can be achieved, making it highly adaptable.

[0036] Step 3: Final Locking and Functional Expansion. After sliding the latch to the target position, screw a bolt into the threaded hole of the lower clamping member 2 through the first through hole 13 in the middle of the upper clamping member 1. As the bolt tightens, it pulls the upper and lower clamping members closer together, thereby forcefully clamping the bent edge of the bracket and achieving final secure fixing. At this point, the external mounting components can be installed using this bolt.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
