Detailed description of the invention

The present invention as shown in figures 1-8, comprises matrix 1, A latch 2, B latch 3, lock pin 4, A spring card pole 5, B spring card pole 6, left spring 7 and right spring 8;

Described matrix 1 is provided with a level trough 11 and pair of parallel A groove 12, B groove 13, described A groove and B groove respectively perpendicular to described level trough,

Described A latch 2 is movably connected in described A groove 12 by described A spring card pole 5, and described B latch 3 is movably connected in described B groove 13 by described B spring card pole 6, and A latch is identical with the structure of B latch, and A spring card pole is identical with the structure of B spring card pole;

Described A latch and B latch are respectively equipped with chute, described lock pin level to be located in described level trough and to be positioned at the chute of described A latch and B latch, described left spring 7 and right spring 8 are located at the two ends of described lock pin respectively and are positioned at described level trough, and lock pin is moved horizontally;

As shown in Figure 4, the inner side of described lock pin 4 is provided with a recess 41, and described recess is consistent with the cross section of described chute, the bottom surface laminating A latch of recess or the face towards lock pin (i.e. the end face of chute) of B latch, make the recess of lock pin when moving to chute, A latch or B latch can be opened;

The bottom surface of described lock pin 4 is provided with card column hole 42, and described card column hole is for placing described A spring card pole or B spring card pole (namely placing A card column or B card column) and being positioned at the outside of described recess.

Described A spring card pole 5 comprises A card column 51 and A spring 52, and described A card column is positioned at the top of A spring; Described B spring card pole 6 comprises B card column and B spring, and described B card column is positioned at the top of B spring.

The both sides, top of described matrix 1 are respectively equipped with A safety rope connecting ring 101 and B safety rope connecting ring 102, and described A latch is provided with A safety rope connecting ring 101, B latch and is provided with B safety rope connecting ring 102.

The outside of described lock pin 4 is provided with switch 9, is convenient to band pendulum lock pin 4 horizontal balance.

As viewed in figures 5-8, described A card column 51 comprises the column body 511 and lower prop 512 that are connected as a single entity, is provided with embedding 513 between the side of described column body 511 and the end face of lower prop 512, and described A latch 2 is located on described embedding 513, arrange embedding and form accommodation space, be convenient to support A latch; For moving horizontally of follow-up lock pin, column body is embedded in card column hole, thus the elastic force of release A spring, A latch is ejected;

The end face of described column body 511 is fitted the bottom surface of described lock pin 4, and described column body 511 and card column hole 42 are positioned on same level direction.

The column body of the integration of A card column and the connection of lower prop, can be realized column body and reliably be connected in card column hole, can realize again under the effect of A spring, be upspring reliably by A latch by embedding, handled easily, improve the reliability of work.

The present invention utilizes the mechanical equivalent of light feature of chain lock safety buckle, and the moment reminds ascend operation personnel specification to use of seat belts, and stopping operating personnel opens major and minor safety rope simultaneously unlawful practice when changing safety rope position, confirming personnel's job safety.

The present invention compared with prior art, its remarkable advantage:

(1), realize the forced blocking of major and minor safety rope, guarantee that the safety belt moment is in safeguard protection state.

(2), product closedown structure is simple, easy to use.

(3), product is firm, meets safety requirements.

The course of work of the present invention is: when double bolt all inserts, and lock pin is held in centre position based on the thrust of left and right spring, and the two end portions of lock pin recess is major and minor by A, B(simultaneously) latch locking, now major and minor latch all processes safe lock state.

When needing to open A latch, pull switch linkage lock pin slides to A latch direction, when lock pin recess slides corresponding with the chute of A latch, the card column that A spring card pole below A latch is reserved with lock pin bottom surface is simultaneously cheated corresponding, be in store power state because A spring card pole withstands lock pin always, when cheating corresponding with the card column of lock pin, A latch has been ejected unblock by its own resilient, cheat rigid contact by lock pin locking with card column simultaneously, thus lock pin can not slide to B latch direction, cannot open B latch again in this state.

Like this, when needing to open B latch, A latch must be turned back to A slot.When A latch turns back to original position, withstand below A spring card pole, cheated by A spring card pole be separated with the card column of lock pin, the locking that lock pin departs from A spring card pole is subject to the elastic force of A latch side left spring to B latch Slideslip, returns to centre position, and by A latch locking.B latch and in like manner above-mentioned is opened in realization.
