Description
Technical field
The utility model relates to Tiandi lock technical field, more specifically to a kind of double hook Tiandi lock locking mechanism.
Background technology
Existing Tiandi lock is generally to drive world hook horizontal linear to move back and forth by master lock tongue, then by master lock tongue and secondary lock tongue by door locking, its weak point is: its locking point only has two, locking firmness and security performance need further to be improved.
Summary of the invention
The purpose of this utility model is exactly the deficiency for prior art, and a kind of double hook Tiandi lock locking mechanism is provided, and it has increased rises to the bait and two locking points of lower hook, makes Tiandi lock locking more firm, and security performance is better.
Technology solution of the present utility model is as follows
Double hook Tiandi lock locking mechanism, comprise master lock tongue, lock body lid, upper connecting rod and lower link, master lock tongue is arranged on lock body and covers, master lock tongue drives upper connecting rod and lower link straight reciprocating motion, rise to the bait and formed by arc coupler body and supporter, on supporter, form jointed shaft, two cylindrical bumps are molded over respectively in the upper and lower surface of supporter, form several teeth on cylindrical bump;
Jointed shaft is hinged on lock body and covers, and side slat and lock body lid are fixed together, and on side slat, forming rises to the bait stretches out hole and the bonnet lock hole of rising to the bait, and one end of arc coupler body is inserted to rise to the bait and stretched out in hole, forms upper connecting rod bar tooth on upper connecting rod, and bar tooth is meshed with tooth.
The structure of described lower hook with rise to the bait identically, the tooth on lower hook is meshed with the drop-down bar strip tooth on lower link, forms lower hook and stretch out hole and lower hook lock button hole on side slat, one end of lower hook is inserted lower hook and is stretched also in hole.
Described several teeth centered by the axial line of cylindrical bump annular spread on cylindrical bump.
The beneficial effects of the utility model are:
It has increased rises to the bait and two locking points of lower hook, makes Tiandi lock locking more firm, and security performance is better.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic perspective view that the utility model is risen to the bait;
Fig. 3 is the structural representation at position, place of rising to the bait while retracting of rising to the bait;
Fig. 4 is the structural representation at position, place of rising to the bait while stretching out of rising to the bait.
In figure: 1, upper connecting rod; 11, upper connecting rod bar tooth; 2, rise to the bait; 21, arc coupler body; 22, supporter; 23, cylindrical bump; 24, tooth; 25, jointed shaft; 3, master lock tongue; 4, lower hook; 5, lower link; 51, drop-down bar strip tooth; 6, lock body lid; 7, side slat; 71, rise to the bait and stretch out hole; 72, the bonnet lock hole of rising to the bait; 73, lower hook stretches out hole; 74, lower hook lock button hole.
the specific embodiment:
Embodiment: see shown in Fig. 1 to 4, double hook Tiandi lock locking mechanism, comprise master lock tongue 3, lock body lid 6, upper connecting rod 1 and lower link 5, master lock tongue 3 is arranged on lock body lid 6, master lock tongue 3 drives upper connecting rod 1 and lower link 5 straight reciprocating motions, rises to the bait 2 arc coupler body 21 and supporter 22, to consist of, and forms jointed shaft 25 on supporter 22, two cylindrical bumps 23 are molded over respectively in the upper and lower surface of supporter 22, form several teeth 24 on cylindrical bump 23;
Jointed shaft 25 is hinged on lock body lid 6, side slat 7 is fixed together with lock body lid 6, and on side slat 7, forming rises to the bait stretches out hole 71 and the bonnet lock hole 72 of rising to the bait, and one end of arc coupler body 21 is inserted to rise to the bait and stretched out in hole 71, on upper connecting rod 1, form upper connecting rod bar tooth 11, bar tooth 11 is meshed with tooth 24.
The structure of described lower hook 4 with rise to the bait 2 identically, the tooth 24 on lower hook 4 is meshed with the drop-down bar strip tooth 51 on lower link 5, forms lower hook and stretch out hole 73 and lower hook lock button hole 74 on side slat 7, one end of lower hook 4 is inserted lower hook and is stretched also in hole 73.
Described several teeth 24 centered by the axial line of cylindrical bump 23 annular spread on cylindrical bump 23.
Operating principle: as shown in Figure 3, master lock tongue 3 drives upper connecting rods 1 to move downward, upper connecting rod bar tooth 11 drives to rise to the bait and 2 turns clockwise, in the retraction lock body of rising to the bait lid 6.
As shown in Figure 4, master lock tongue 3 drives upper connecting rods 1 to move upward, and upper connecting rod bar tooth 11 drives to rise to the bait and 2 is rotated counterclockwise, and rises to the bait and stretches out outside lock body lid 6.
The utility model utilizes the principle of rack drives gear rotation, makes to rise to the bait and lower hook fast rotational, reaches to rise to the bait and lower hook stretches out and retracts, and locks a door and opens the door object.
