Description

Technical Field

[0001] This utility model relates to the field of mechanical connection and fixing technology, specifically to a quick locking device. Background Technology

[0002] In many fields such as machinery manufacturing, equipment maintenance, and automated production lines, it is frequently necessary to connect and secure components. Traditional connection methods, such as bolt and nut connections, while providing relatively reliable fastening, have several inconveniences in practical operation. Using bolt and nut connections requires the use of tools such as wrenches for tightening and loosening, which is cumbersome and time-consuming, especially in situations requiring frequent disassembly and installation, making it extremely inefficient. Furthermore, with prolonged use, thread wear accelerates, leading to misalignment, affecting installation, or even reducing the tightening effect, potentially causing loosening or detachment, further impacting safety and convenience. In addition, in some space-constrained work environments, using wrenches and other tools is difficult or even impossible.

[0003] While some existing quick-connect devices improve connection speed to a certain extent, they are insufficient in terms of connection stability. During equipment operation, when subjected to external forces such as vibration and impact, these quick-connect devices are prone to loosening, leading to connection failure, affecting the normal operation of the equipment, and may even cause safety accidents. Summary of the Invention

[0004] The purpose of this invention is to provide a quick locking device to solve the problems of cumbersome operation, low efficiency, and insufficient stability of existing quick connection methods.

[0005] To achieve the above objectives, the quick locking device of this utility model mainly includes a lock cap, an anti-loosening component, a lock body, and a lock nut.

[0006] The lock cap serves as both the main connecting structure and an auxiliary load-bearing structure. It controls the rotation and fastening of the lock body. The back of the lock cap has a wear-resistant threaded hole for connecting to the lock body and also acts as a limiting device for the anti-loosening component, preventing the anti-loosening component from falling off the lock body and becoming ineffective.

[0007] The anti-loosening component is a lock cavity structure with a threaded through hole inside, allowing it to rotate on the lock body. The anti-loosening component is installed on the lock body, positioned between the lock cap and the object being locked. Once fully engaged, rotating the anti-loosening component completely tightens the locking mechanism.

[0008] The lock body is made of an alloy material with pressure resistance and wear resistance. The upper end is threaded to connect with the anti-loosening component and the lock cap, and the lower end is equipped with a lock buckle to cooperate with the lock nut to complete the locking action. Its internal mating surface is at a negative angle. When it is used for hoisting, the greater the pulling force, the tighter the fit. Under normal use, after being locked by the anti-loosening component, it can achieve the functions of tensile resistance and preventing falling off.

[0009] The lock nut has a concave, recessed structure with a cross-shaped opening at the top to accommodate the insertion of the lock body. Internally, it features alternating short and long pins. The long pins act as a limiting mechanism; after the lock body is inserted, a slight rotation locks it in place. The short pins are designed with a negative angle; when the lock body is locked in place and tightening is performed, they fit tightly against the negative angled surface of the lock body, achieving tightening and positioning, and preventing it from falling out.

[0010] The anti-loosening component is set on the thread of the lock body, and the lock cap thread is installed on the thread of the lock body, forming a whole. The lock nut is installed in the object to be secured, the lock body is inserted into the lock nut, the lock cap is rotated so that the lock body locking pin is locked in the lock nut limit position, and the rotating wrench is turned so that the lock body mating surface and the lock nut mating surface are tightly pressed together.

[0011] Compared with existing technologies, the advantages of this utility model are as follows: It is convenient and efficient to operate. The lock body rotates via the lock cap, and upon reaching the limit, the anti-loosening component tightens, achieving complete locking. No additional tools are needed; operators can quickly lock and unlock simply by manually moving the lock cap and anti-loosening component, significantly shortening connection and disassembly time and improving work efficiency. The connection is stable and reliable. The unique design of the lock body and lock nut ensures accurate connection and effectively avoids connection deviations. The anti-loosening component prevents loosening caused by external forces during equipment operation, ensuring connection stability. The embedded negative angle mating surface enables self-locking and anti-loosening under any conditions of self-weight and locking, improving the safety and reliability of equipment operation. It has wide applicability. The lock body's connection interface can be customized according to different needs, suitable for connecting components of various shapes and specifications, and can meet the usage requirements of different fields and equipment.

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] When connecting components using this quick-locking device, first install the anti-loosening component 21 onto the threaded part of the lock body 31, and then install the lock cap thread 13 of the lock cap 11 onto the threaded part of the lock body 31 to form a single unit. Install the lock nut 41 into the object to be locked, ensuring it is flush with the object. Then, begin locking: insert the assembled lock body 31 into the lock nut 41, rotate the lock cap 11 to engage the lock body locking pin 33 with the lock nut limit 43, and then turn the rotary wrench 23 to bring the lock body mating surface 32 and the lock nut mating surface 42 into tight contact, thus achieving locking.

[0021] When it is necessary to disassemble the connecting parts, first use a tool to turn the rotary wrench 23 to release the lock body 31 from the lock nut 41, separating the lock body mating surface 32 from the lock nut mating surface 42. Rotate the lock cap 11 to disengage the lock body locking pin 33 from the lock nut limit 43. Then pull out the lock cap 11 to disengage it from the connection structure of the part to be connected. At this point, the two connecting parts can be separated, completing the disassembly operation.
