Detailed Description
As shown in fig. 1 and 2, a novel durable lock body structure, including drain pan 1, the tongue main part 2 that slides and set up in drain pan 1 rotates the handle shifting block 3 of connecting in drain pan 1 and stirring the tongue main part 2 withdrawal drain pan 1, and the drive tongue main part 2 stretches out the outer elastic component that resets of drain pan 1, handle shifting block 3 extends there is stirring arm 301, tongue main part 2 protruding is equipped with spacing sloping block 201, stir one side of arm 301 direction of rotation and stir spacing sloping block 201 of butt, spacing sloping block 201 along with stirring arm 301 butt face extend have with stirring arm 301 reinforcing piece 202 that closely laminates. When the lock is unlocked, the handle shifting block 3 is rotated through the handle, the shifting arm 301 of the handle shifting block 3 rotates and is tightly abutted against the reinforcing sheet 202 of the limiting inclined block 201 on the lock tongue main body 2 through one side of the rotating direction of the shifting arm 301, and the lock tongue main body 2 can be directly driven to slide and retract into the bottom shell 1 easily and uniformly under stress; and unblank the back, it slowly resets outside the drain pan 1 that stretches out the lock body even to reset elastic component drive spring bolt main part 2, promote with the enhancement piece 202 that dials the arm 301 butt and dial arm 301 antiport, make handle shifting block 3 and handle rotate the return, whole process enhancement piece 202 and dial arm 301 closely butt always on a large area ground, the part area of contact of butt is little and the part that leads to sharply wears and reduces the noise that wearing and tearing brought in the effective traditional technique that reduces, the part collision sound of the transmission of the lock body of many link structures when using in the traditional technique has also been avoided, the extension lock body life-span, promote product use and experience.
In order to further make the contact between the shift arm 301 and the reinforcing plate 202 tighter, an avoiding groove 302 is recessed on one side of the shift arm 301 in the rotation direction corresponding to the edge of the reinforcing plate 202.
Reset the elastic component and be extension spring 4, drain pan 1 slides in spring bolt main part 2 and stretches out one side of drain pan 1 and be equipped with the lock tongue hole 101 that matches spring bolt main part 2 and stretch out the end, drain pan 1 is protruding to be equipped with first projection 102 in one side of lock tongue hole 101, be equipped with second projection 203 on the spring bolt main part 2, first projection 102 and second projection 203 are connected respectively to extension spring 4's both ends, through the characteristics of direction pulling between the point-to-point side of extension spring 4, make the end that stretches out of spring bolt main part 2 restore to the throne more fast and stretch out drain pan 1, avoided the off tracking phenomenon that the end that stretches out of spring bolt main part 2 probably appears at the in-process that resets.
In order to avoid noise caused by friction between the extension spring 4, the bottom case 1 and the bolt body 2 when the lock body works, the limiting rings 5 are tightly sleeved at the upper end and the lower end of the connection between the first convex column 102 and the second convex column 203 and at the position of the connection between the extension spring 4, and meanwhile, the limiting rings 5 also play a role in fixing the extension spring 4, so that the phenomenon that the extension spring 4 possibly falls off from the first convex column 102 and the second convex column 203 is further avoided.
In order to further reduce the deviation phenomenon which may occur in the return process of the lock tongue main body 2, the lock tongue main body 2 is provided with a guide long circular hole 204 along the sliding direction, a position limiting guide piece 103 matched with the guide long circular hole 204 is convexly arranged at the position of the bottom shell 1 corresponding to the guide long circular hole 204, and when the lock tongue main body 2 is pulled by the extension spring 4 to return, the lock tongue main body 2 slides along the direction of the limiting guide piece 103.
Bottom shell 1 is equipped with the spacing projection 104 with stirring arm 301 rotation direction opposite side butt to bottom shell 1 epirelief, and spacing projection 104 when spring bolt main part 2 slides and resets with enhancement piece 202 cooperation centre gripping stirring arm 301 for handle shifting block 3 and handle can not driven too much the reversal after spring bolt main part 2 slides and resets.
In order to make handle shifting block 3 and the handle that links to each other with handle shifting block 3 return more fast, and both angles do not take place to deflect after the return, still be equipped with handle shifting block reset spring 6, handle shifting block 3 extends reset arm 7, handle shifting block reset spring 6's both ends support respectively and lean on the lateral wall and the arm 7 that resets of drain pan 1, handle shifting block reset spring 6 promotes reset arm 7 and rotates along the opposite direction of shifting arm 301 rotation direction and make shifting arm 301 and spacing projection 104 keep the butt state.
In order to avoid the dropping phenomenon that shifting block reset spring studio probably appears, reset arm 7 has guide bar 701 to handle shifting block reset spring 6 extension, be equipped with spring guiding hole 105 on the 1 lateral wall of drain pan, it has spring adjusting screw 8 to connect soon in the spring guiding hole 105, 6 suit guide bar 701 of handle shifting block reset spring and one end butt reset arm 7, the other end penetrate spring guiding hole 105 and butt spring adjusting screw 8, and when long-time the back of using, shifting block reset spring ageing and warp and influence the return of handle shifting block 3, only need adjust spring adjusting screw 8 compression shifting block reset spring's stroke alright make shifting block reset spring normally work.
In order to reduce the abrasion between the extending end of the bolt body 2 and the two sides of the bolt hole 101, nylon wear-resistant blocks 9 are embedded on the two sides of the bolt hole 101 corresponding to the extending end of the bolt body 2
In order to reduce the abrasion to the latch bolt body 2 when the door is closed in daily use, the extending end of the latch bolt body 2 is provided with an inclined tongue 10 connected with the latch bolt body 2, the inclined tongue 10 is provided with an inclined surface, the inclined surface is provided with a groove, a wear-resistant sliding block 11 exposed out of the inclined surface of the inclined tongue 10 is embedded in the groove, the exposed surface of the wear-resistant sliding block 11 is a collision surface, the collision surface protrudes out of the inclined surface of the inclined tongue 10, when the door is closed, the collision surface of the wear-resistant sliding block 11 protruding out of the inclined surface of the inclined tongue 10 replaces the inclined surface of the inclined tongue 10 to collide with a door frame, when the wear-resistant sliding block 11 is abraded until the collision surface is flush with the inclined surface of the inclined tongue 10, only a new wear-resistant sliding block 11 or the inclined tongue 10 needs.
