Description

Fixing Wire Rope Lock Head

Technical field

The present invention relates to a kind of Wire Rope Lock Head.

Background technology

The general fixedly pins type structure that adopts of steel cable lock of the prior art, promptly the end at wirerope is provided with fixedly pin, and the other end of wirerope is fixedly connected with tapered end, accomplishes locking in the pin holes that fixedly pin insertion tapered end is provided with during use.The said structure steel cable lock is owing to adopt fixedly pins type structure; Therefore the wirerope length of its locking is uncontrollable, is not suitable for strapping goods, promptly is used in strapping goods (can adopt the mode of coiling); Its use neither be very convenient, and the fastness of tying up is bad.

Summary of the invention

Technical problem to be solved by this invention provides a kind of fixedly Wire Rope Lock Head that makes things convenient for strapping goods.

For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of fixedly Wire Rope Lock Head comprises upper casing, stop, dial, ratchet, lower casing, lock core; Said lower casing is provided with the lock core column that lock core is installed, and stop is enclosed within the lock core column rotationally, is provided with the stop spring between stop and the lock core column; The end of lock core column is provided with the dial that matches with the lock core thumb wheel, and dial can drive stop and rotate, and the adjacent stop of ratchet also is slidably disposed on the lower casing; Be provided with ratchet spring between ratchet and the lower casing; The periphery of stop is provided with the ratchet that matches with ratchet, and ratchet is provided with projection, and the periphery of dial is provided with the slide rail that matches with the projection of ratchet; Upper casing covers with following shell facies; Be provided with between upper casing and the lower casing and hold the wirerope through hole that wirerope passes, the sidewall that lower casing and stop are relative is provided with the housing tooth bar, and stop is provided with the stop tooth bar.

The present invention fixedly beneficial effect of Wire Rope Lock Head is: hold the wirerope through hole that wirerope passes owing to be provided with between upper casing and the lower casing; Free end with wirerope during use passes the wirerope through hole; Through the locking of incompatible realization that match of stop tooth bar on the stop and the housing tooth bar on the lower case side wall to wirerope; Therefore as long as, can steel cable lock be fixed on any position, use very convenient toward a direction pulling wirerope; Because lower casing is provided with slidably ratchet, when the rotational lock core certain angle, the projection of ratchet matches with the protruding place of the slide rail of dial in addition; Make ratchet break away from the ratchet of stop, this moment, stop was rotatable, this moment wirerope in the past a direction pull out; And draw and lock toward another direction, and when rotational lock core certain angle again, the projection of ratchet matches with the slide rail recess of dial; Make ratchet get into the ratchet of stop; This moment, stop was locked, and this moment, wirerope also by thorough locking (which direction drawing wirerope all to be locked toward), therefore was suitable for strapping goods very much.

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further description.

Description of drawings

Fig. 1 is the fixedly decomposition texture sketch map of a kind of embodiment of Wire Rope Lock Head of the present invention;

Fig. 2 is the fixing overall fit structural representation of Wire Rope Lock Head among Fig. 1;

Fig. 3 is the A-A sectional view among Fig. 2.

The specific embodiment

Like Fig. 1, Fig. 2, shown in Figure 3, the present invention is a kind of embodiment of Wire Rope Lock Head fixedly, comprises upper casing 1, stop 19, dial 17, ratchet 7, lower casing 13, lock core 10; Said lower casing 13 is provided with the lock core column 14 that lock core 10 is installed, and stop 19 is enclosed within the lock core column 14 rotationally, is provided with stop spring 4 between stop 19 and the lock core column 14; The end of lock core column 14 is provided with the dial 17 that matches with the lock core thumb wheel, and dial 17 can drive stop 19 and rotate, and ratchet 7 adjacent stops 19 also are slidably disposed on the lower casing 13; Be provided with ratchet spring 8 between ratchet 7 and the lower casing 13; The periphery of stop 19 is provided with the ratchet 3 that matches with ratchet 7, and ratchet 7 is provided with projection 6, and the periphery of dial 17 is provided with the slide rail 5 that matches with the projection 6 of ratchet 7; Upper casing 1 covers with lower casing 13 mutually; Be provided with between upper casing 1 and the lower casing 13 and hold the wirerope through hole 11 that wirerope passes, lower casing 13 is provided with housing tooth bar 12 with stop 19 relative sidewalls, and stop 19 is provided with stop tooth bar 18.In order to make structure simpler; The end of said stop 19 is provided with vertical projection 2; The periphery of said dial 17 is provided with the horizontal raised line 9 that matches with the vertical projection 2 of stop 19; When dial 17 counterclockwise sides rotated together, the horizontal raised line 9 of dial 17 matched with the vertical projection 2 of stop 19 and can drive stop 19 rotation counterclockwise.In order to increase the rotation feel; Be provided with hoodle 16 and hoodle spring 15 between said dial 17 and the lock core column 14; The end face that said dial 17 matches with lock core column 14 is provided with three shrinkage pools that semicircle along the circumferential direction evenly distributes and matches with hoodle 16, and moving 90 degree of lock core 10 revolutions, hoodle 16 snap in respectively in the shrinkage pool that dial 17 is provided with; Thereby make lock core 10 rotation class clearly demarcated, have good rotation feel.

The present invention fixedly operating principle of Wire Rope Lock Head is: like Fig. 1, shown in Figure 2, during use, the free end of wirerope 20 is passed wirerope through hole 11; Rotational lock core 10 is in half lock-out state, owing to be provided with stop spring 4 between stop 19 and the lock core column 14, stop 19 is under the effect of stop spring 4; The stop tooth bar 18 of stop 19 contacts with the surface of wirerope 20 all the time; And with the housing tooth bar 12 of lower casing 13 match incompatible realization to the folk prescription of wirerope 20 to locking, this moment, the projection 6 of ratchet 7 matched with the slide rail 5 protruding places of dial 17, made the ratchet 3 of ratchet 7 disengaging stops 19; This moment, stop 19 can counterclockwise rotate; This moment, wirerope 20 direction of can turning left from the right side was pulled out, and direction is drawn and locked from left to right, and promptly wirerope 20 is in half lock-out state; Clockwise rotate lock core 90 degree this moment; Lock core 10 drives dial 17 clockwise directions and rotates 90 degree; This moment, the projection 6 of ratchet 7 matched with slide rail 5 recesses of dial 17, made ratchet 7 get into the ratchet 3 of stop 19, and this moment, stop 19 was locked; Also by thorough locking (which direction drawing wirerope all to be locked toward), promptly wirerope 20 is in the lock state wirerope 20 at this moment; When needs are unblanked; Counterclockwise rotational lock core 180 is spent; Lock core 10 drives dial 17 and counterclockwise rotates 180 degree, and dial 17 drives stop 19 and counterclockwise rotates 90 degree, and this moment, the stop tooth bar 18 of stop 19 broke away from wirerope 20 surfaces; Both direction can spur wirerope 20, and wirerope 20 is in released state.
