Detailed Description
The conception, the specific structure and the technical effects of the present invention will be further described with reference to the accompanying drawings, so as to fully understand the objects, the features and the effects of the present invention.
With reference to fig. 1-6 of the specification, a light-force and reversing-free anti-insertion functional lock body comprises a lock box 1, an anti-insertion top piece 2, a fixing plate 3, an oblique tongue component 4, an anti-insertion tongue component 5 and a pin 6, wherein the cross section of the lock box is rectangular, a hollow cylinder 103 facing upwards is arranged on the bottom surface of the lock box 1, an anti-insertion tongue hole 102 and a rectangular oblique tongue hole 101 are formed in the side surface of the lock box, the oblique tongue component 4 is installed in the oblique tongue hole 101, the anti-insertion tongue component 5 is installed corresponding to the anti-insertion tongue hole 102, circular openings corresponding to the cylinder 103 are formed in the anti-insertion top piece 2 and the fixing plate 3, an upward second cylinder is fixedly arranged on the circular opening of the fixing plate 3, a torsion spring is sleeved on the circumference of the second cylinder, and the anti-insertion tongue component 5 is installed at the front end of the fixing.
The front end of the fixed plate 3 is vertically and fixedly provided with a mounting plate, and the two sides of the anti-insertion tongue component 5 are all arranged in a radian manner.
The front end of the mounting plate is provided with an arc-shaped boss 301, the center of the arc is provided with a positioning hole 302, the inner side of the anti-insertion tongue component 5 is longitudinally provided with an arc-shaped groove 501 matched with the arc-shaped boss 301, the transverse center of the anti-insertion tongue component 5 is provided with a pin hole 502 in a penetrating manner, and the pin 6 is fixedly mounted in the pin hole 502 and penetrates through the positioning hole 302.
The radian of the arc-shaped boss 301 is not less than 240 degrees, and two limiting blocks 503 are further longitudinally and fixedly arranged on two sides of the anti-insertion tongue component 5.
The latch bolt component 4 is provided with a limit groove corresponding to the cylinder 103, the limit groove is integrally in a combined shape of a rectangle and semicircles at two ends of the limit groove, and the radius of the semicircle is matched with that of the cylinder 103.
In this is novel, pin 6 and pin hole 502 interference fit, pin 6 and locating hole 302 clearance fit prevent that tongue 5 and pin 6 and fixed plate 3 can the rotation each other. As shown in fig. 4 and 5, when the door is closed, the anti-inserting tongue 3 swings at a certain angle corresponding to the direction when it touches the buckle plate of the door frame.
As shown in fig. 7, the latch bolt pushing surface 401 is disposed on the latch bolt assembly 4, the fixing plate driven surface 303 is disposed on the fixing plate 3, when the door is closed, the latch bolt assembly 4 will first touch the door lock plate on the door frame because the length of the latch bolt assembly 4 is longer than that of the anti-insertion bolt 5, so that the latch bolt assembly 4 will first retract into the lock body, and after entering a certain stroke, will drive the fixing plate 3 and the anti-insertion bolt 5 to retract into the lock body at the same time.
When the door is closed, the anti-insertion tongue 5 can swing along with the door closing direction, the friction between the anti-insertion tongue 5 and the door frame can be effectively reduced without dividing the left direction and the right direction, and the anti-insertion tongue 5 is driven by the oblique tongue component 4 to retract into the lock body, so that the force for closing the door can be greatly reduced.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
