Description

Technical Field

[0001] This utility model relates to a quick-locking mechanism, belonging to the technical field of machine tools and devices used for grinding or polishing. Background Technology

[0002] In the field of prefabricated manufacturing, it is often necessary to quickly and reliably connect and fix multiple prefabricated panels. Traditional connection methods often involve direct fastening with screws and angle brackets, complex hardware assembly, or other clamps, which have problems such as cumbersome operation, low efficiency, high technical requirements for workers, and inconvenient disassembly.

[0003] Existing technologies include "three-in-one connectors" used in the furniture industry, which typically consist of a screw, an eccentric wheel, and a pre-embedded nut, using the locking principle of the eccentric wheel to connect the panels. However, this type of connector cannot be directly applied to the field of prefabricated manufacturing, and it still suffers from problems such as cumbersome operation and low efficiency.

[0004] Therefore, there is an urgent need in this field for a quick-install lock that is highly integrated, extremely easy to operate, reliably locks, and has an anti-loosening function. Summary of the Invention

[0005] This utility model addresses the shortcomings of the existing technology by providing a quick lock that is highly integrated, fast to operate, reliable in locking, and has anti-loosening function.

[0006] The purpose of this utility model is achieved through the following technical solution: a quick lock, including a mounting plate, the mounting plate is provided with several sets of locking mechanisms, the locking mechanism includes a flip handle and an eccentric fastener, the flip handle includes a handle body with anti-slip texture on the surface and an anti-slip snap fastener, the eccentric fastener is connected to the flip handle and flips with it, and the plates are connected by clamping and fixing several sets of connecting rods pre-embedded in multiple plates.

[0007] Furthermore, the mounting plate is equipped with at least two sets of locking mechanisms.

[0008] Furthermore, the anti-slip snap fastener includes a hook-shaped buckle and a guide mounting component. One end of the buckle is provided with a guide slide rod. The inner side of the guide mounting component is provided with a semi-circular slide groove for the guide slide rod to slide inside it. A spring is provided between the end of the guide slide rod and the end of the semi-circular slide groove. The flip handle also includes a sliding push component. The sliding push component includes an arc-shaped pressing plate with anti-slip texture on its surface and a push rod fixedly provided at its bottom.

[0009] Furthermore, the middle part of the push rod is connected to the groove on the handle body through a pivot, and the end of the guide slide rod is fixed with a fixing post for sleeved spring to prevent it from deviating. The guide mounting part is installed in the groove inside the handle body and fixed with screws.

[0010] Furthermore, the eccentric fastener includes a columnar, horizontally positioned eccentric wheel, with a mounting housing on the outer side of the eccentric wheel, and an anti-slip ratchet tooth on the outer side of the mounting housing that cooperates with the anti-slip snap fastener. The inner side of the eccentric wheel is provided with an eccentric locking groove for locking the end of the connecting rod.

[0011] Furthermore, the two ends of the eccentric wheel are fixed to the flip handle by two screws not on the axis of the eccentric wheel. The anti-slip ratchet is embedded in the semi-circular surface on the outer side of the mounting housing, that is, on the flip path of the flip handle itself from vertical to horizontal. The hook-shaped buckle engages with the ratchet on the surface of the anti-slip ratchet to achieve the anti-slip effect.

[0012] Furthermore, the top of the mounting plate is provided with mounting slots corresponding to the number of mounting housings, the mounting housings are embedded in the mounting slots and fixed by screws, and the eccentric wheel is installed inside the mounting housing and is rotatably connected.

[0013] Furthermore, when the latch is in the open state, the larger opening end of the eccentric locking groove faces downward and the smaller opening end faces outward; when the latch is in the closed state, the larger opening end of the eccentric locking groove faces inward and the smaller opening end faces downward, locking the end of the connecting rod.

[0014] Furthermore, the bottom of the mounting slot is provided with a through hole for the connecting rod to pass through.

[0015] A method for using a quick-locking latch includes the following steps: S1: Install connecting rods at the corners of several panels; S2: Keep all flip handles vertical, i.e., the latch is in the open position; S3: Align the several through holes with the connecting rods respectively, then lower the locking buckle until the end of the connecting rod is inserted into the eccentric locking groove; S4: Turn the flip handle outward to drive the eccentric wheel to flip synchronously so that the end of the connecting rod is locked by the smaller opening end of the eccentric locking groove; S5: Push the sliding component to release the push rod. After losing resistance, the buckle is pushed outward by the spring until the hook-shaped buckle engages with the ratchet teeth on the surface of the anti-slip ratchet component to achieve the anti-slip effect.

[0016] In summary, compared with the prior art, this utility model has the following advantages: 1. In this utility model solution, multiple connection points can be locked simultaneously with only three actions: aligning, lowering, and flipping the handle. The operation is extremely fast and simple, greatly improving installation efficiency and reducing the technical requirements for operators. 2. In this utility model, the self-locking principle of the eccentric wheel is utilized, which has a large locking force and can make the plates fit tightly together. The design of multiple locking mechanisms ensures the balance and overall stability of the connection, making the locking reliable and the connection stable. 3. In this utility model, the innovative anti-slip locking mechanism and ratchet part have an automatic anti-loosening function. After locking, they automatically engage to form a mechanical interlock, which effectively avoids loosening that may occur in a vibration environment, and has high safety and reliability. 4. In this utility model, disassembly is convenient. When disassembly is required, simply press the sliding pusher to separate the buckle from the ratchet, then flip the handle back and easily remove the entire lock. This achieves quick disassembly, which is convenient for maintenance and reuse. 5. In this utility model, the integrated design integrates all moving parts onto the mounting plate to form a single module, avoiding the hassle of assembling multiple small parts on-site and reducing the risk of losing parts.

Each locking mechanism 2 includes a flip handle 3 and an eccentric fastener 4. The flip handle 3 includes a handle body 31 with anti-slip texture on the surface and an anti-slip fastener 32. The eccentric fastener 4 is connected to the flip handle 3 and flips accordingly. The connection of the plates is achieved by clamping and fixing several sets of connecting rods pre-embedded in multiple plates.

[0021] The mounting plate 1 is equipped with at least two sets of locking mechanisms 2.

[0022] The anti-slip snap fastener 32 includes a hook-shaped buckle 321 and a guide mounting part 322. One end of the buckle 321 is provided with a guide slide rod 323. The inner side of the guide mounting part 322 is provided with a semi-circular slide groove 324 for the guide slide rod 323 to slide inside it. A spring 325 is provided between the end of the guide slide rod 323 and the end of the semi-circular slide groove 324. The flip handle 3 also includes a sliding pusher 33. The sliding pusher 33 includes an arc-shaped pressing plate 331 with anti-slip texture on its surface and a push rod 332 fixedly provided at its bottom.

[0023] The middle part of the push rod 332 is connected to the groove on the handle body 31 by a rotating shaft. The end of the guide slide rod 323 is fixed with a fixing post for sleeved spring 325 to prevent it from deviating. The guide mounting part 322 is installed in the groove inside the handle body 31 and fixed with screws.

[0024] The eccentric fastener 4 includes a columnar horizontally placed eccentric wheel 41. The outer side of the eccentric wheel 41 is provided with a mounting housing 42. The outer side of the mounting housing 42 is provided with an anti-slip ratchet 43 that cooperates with the anti-slip snap fastener 32. The inner side of the eccentric wheel 41 is provided with an eccentric locking groove 44 for locking the end of the connecting rod.

[0025] The two ends of the eccentric wheel 41 are fixed to the flip handle 3 by two screws that are not on the axis of the eccentric wheel 41. The anti-slip ratchet 43 is embedded in the semi-circular surface of the mounting housing 42 on the outer side, that is, on the flip path of the flip handle 3 itself from vertical to horizontal. The hook-shaped buckle 321 engages with the ratchet on the surface of the anti-slip ratchet 43 to achieve the anti-slip effect.

[0026] The top of the mounting plate 1 is provided with mounting slots 11 corresponding to the number of mounting housings 42. The mounting housings 42 are embedded in the mounting slots 11 and fixed with screws. The eccentric wheel 41 is installed inside the mounting housing 42 and is rotatably connected.

[0027] When the latch is in the open state, the larger opening end of the eccentric locking groove 44 faces downward and the smaller opening end faces outward. When the latch is in the closed state, the larger opening end of the eccentric locking groove 44 faces inward and the smaller opening end faces downward, locking the end of the connecting rod.

[0028] The bottom of the mounting slot 11 has a through hole 12 for passing through the connecting rod.

[0029] A method for using a quick-locking latch includes the following steps: S1: Install connecting rods at the corners of several panels; S2: Keep all flip handles vertical, i.e., the latch is in the open position; S3: Align the several through holes with the connecting rods respectively, then lower the locking buckle until the end of the connecting rod is inserted into the eccentric locking groove; S4: Turn the flip handle outward to drive the eccentric wheel to flip synchronously so that the end of the connecting rod is locked by the smaller opening end of the eccentric locking groove; S5: Push the sliding component to release the push rod. After losing resistance, the buckle is pushed outward by the spring until the hook-shaped buckle engages with the ratchet teeth on the surface of the anti-slip ratchet component to achieve the anti-slip effect.

[0030] Working Principle: In the initial state of use, the handle is vertical, and the eccentric locking groove 44 is facing downwards. After the connecting rod end falls into the groove, the handle 3 is flipped to a horizontal position. During this process, the eccentric wheel 41 rotates, and the narrow part of its eccentric locking groove 44 clamps the connecting rod end downwards. The cam principle is used to generate a huge locking force in the latch and tighten the plate. When the handle is in position, the spring 325 pushes the latch 321 outwards, engaging with the anti-slip ratchet 43, locking it like a ratchet wrench, preventing the handle from turning back, thus achieving reliable locking and anti-loosening. During disassembly, press the sliding pusher 33 to hold the latch 321 in place, causing the latch 321 to retract and disengage from the ratchet, allowing the handle to be flipped back to unlock.

[0031] The embodiments of this utility model are not limited to those described above. Without departing from the spirit and scope of this utility model, those skilled in the art can make various changes and improvements to the form and details of this utility model, and these are all considered to fall within the protection scope of this utility model.
