Description

TECHNICAL FIELD

[0001] The utility model relates to fast plug buckle technical field, concretely relates to a fast plug buckle with connecting point. BACKGROUND

[0002] The fast plug buckle is the core connecting device in the field of rope rescue and aerial work, and is mainly used for quickly establishing the safe connection between personnel and anchor points and equipment. Its core function is to realize the quick operation of "one insertion and locking, and double pressing and opening" while bearing high dynamic load. The device is widely used in fire rescue, mountain climbing protection, industrial aerial work and other scenes, and is the key equipment for protecting the life safety of workers.

[0003] The current mainstream left-right split fast plug buckle includes the following structures: a shell assembly: a symmetrical split design, a lock tongue accommodating cavity is arranged in the middle part, and a pressing guide groove is arranged on both sides; a locking mechanism: a single straight-tooth lock tongue (mostly nylon or ordinary steel), which realizes the insertion rod clamping through spring pre-tightening; an unlocking mechanism: double-sided independent pressing buttons, and any single side force ≥ 50N can trigger the lock tongue to retract. The working mode of the left-right split fast plug buckle is as follows: when the insertion rod is inserted, the lock tongue pushes the spring, and after reaching the clamping position, the lock tongue pops up to complete the locking; when unlocking, the two buttons need to be pressed at the same time, and the lock tongue is released to realize the separation. Although the structure can realize the basic connection function, it has the following significant functional defects:

[0004] Insufficient device compatibility: only a single lanyard fixing hole is arranged, and rescue equipment such as a descender and a safety hook cannot be directly connected, so that the worker has to carry a conversion connector, and the additional conversion connector has a problem of connection stability due to the non-integral structure; in a complex rescue scene (such as multi-rope cooperative work), due to the lack of a secondary connecting point, the topological connection of "single buckle and multiple devices" cannot be realized, so that when the main lock tongue fails unexpectedly, there is no secondary protection provided by the secondary connecting point.

[0059] The working principle of this quick-connect buckle with connection points will be explained in detail below.

[0060] like Figures 1-10 As shown, when the male buckle 1 and the female buckle 2 are inserted, pressing the buckles 203 on both sides simultaneously moves the push block 204 and squeezes the first spring 205, causing the two locking pins 206 to move towards each other. Then, the locking part is inserted into the slot 201. During the insertion process, the two locking pins 206 are located in the center of the two locking plates 405, so they will not block the insertion. After the insertion is in place, the buckles 203 are released, so that the push block 204 and the buckles 203 are reset under the rebound of the first spring 205, and the locking pins 206 are reset and locked into the slot 401, thus completing the connection. When disassembling, simply press the two buckles 203 simultaneously to make the locking pins 206 leave the slot 401, and the locking plate 405 can be pulled out.

[0061] Considering the possibility of accidental activation of the snap fastener 203 during use, an anti-accidental activation component is also provided to avoid risks. When the connector 3 is not used to connect external auxiliary equipment, after the male buckle 1 and female buckle 2 are connected, by rotating the connector 3, the baffles 501 located at both ends of the connector 3 will rotate and cover the snap fastener 203, preventing external force from pressing the snap fastener 203. During the above process, the inclined side of the locking block 504 contacts and is squeezed, causing it to move and squeeze the second spring 503 until the locking block 504 is aligned with the positioning groove 505. Under the elastic force of the second spring 503, the locking block 504 is pushed to move, causing the locking block 504 to pop out and lock into the positioning groove 505, thereby completing the locking and preventing the connector 3 from rotating (both sides are limited by the locking block 504 and the snap fastener 203 respectively).

[0062] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
