Detailed Description
As shown in fig. 1-10, the utility model discloses a pedal type door locking device, which comprises a locking part fixed on the wall and a mechanical transmission device installed on the door, a pressing spring 7 is arranged between the upper and lower plates 4 and 5 of the pedal plate, the upper plate 4 of the pedal plate is connected with a metal pull rope 3, the metal pull rope 3 strides over a steering pulley 2, passes through a rear cover 12, passes through a spring 13, passes through a hole in the middle of a ratchet 10, and is connected with a bolt 9 finally. The inner part of the rear cover 12 is of a hollow structure, the right end of the rear cover is provided with a baffle plate 19, and the center of the baffle plate 19 is provided with a hole for a stay wire to pass through; the inner side of the front cover 11 is provided with a guide rail, and a spring provides elastic force between the right side of the ratchet wheel and the baffle 19. After a user enters a toilet, the user pushes a door to close the door, steps on the upper plate 4 of the pedal by feet, transmits power to the bolt through the metal pull rope 3 and the steering device, the bolt 9 retreats, the indexing claw 14 on the bolt 9 presses the sliding claw 15 on the ratchet wheel 10 to be matched with the guide rail in the rear cover 12, the action principle of the bolt is similar to that of the inside of a pressing type elastic ball pen, the bolt 9 acts as a ball pen pressing head, the pressure of fingers during use is replaced by the pulling force of the pull rope, the pulling force acts once, the bolt 9 pops out to enter the lock catch 8 on the wall, and the door locking is completed; when a user wants to open the door, the user steps on the pedal upper plate 4 again, power is transmitted to the bolt 9 through the metal pull rope 3 and the steering device 2, the bolt is pulled out of the jack fixed on the wall, the internal indexing claw 14, the sliding claw 15 of the ratchet wheel 10 and the guide rail in the rear cover 12 are matched with each other to stop, and then the pedal lower plate 5 is stepped on by the foot to withdraw, so that the door opening is completed.
The utility model discloses the structure and the motion principle of bolt, ratchet, guide rail are the same completely with current push type elasticity ballpoint press down the principle, and the guide rail of ejector pin, carousel, the pen container of pressing the ballpoint is corresponding respectively to the guide rail of bolt, ratchet, protecgulum, and the bolt effect is equivalent to the ballpoint press head, replaces the pressure of finger when using with the pulling force of stay cord, its structure of following simple description and principle:
the bolt is cylindrical, 8 square bulges 18 are arranged around the bolt, eight indexing claws 14 are uniformly distributed at the front part of the bolt, and the indexing claws are triangular; the ratchet wheel is in a hollow rod shape, the front end of the ratchet wheel is uniformly provided with four sliding claws 15, the sliding claws 15 are in inclined plane tooth-shaped structures matched with the indexing claws 14, and the thinner head of the ratchet wheel 10 is inserted into an inner hole of the bolt 9.
The guide rail comprises four bevel double teeth 17 which are symmetrically arranged, a guide groove 18 for square convex movement is arranged in the middle of the inner side of each bevel double tooth 17, and a moving groove 16 for the sliding claw of the ratchet wheel to pass through is arranged between the bevel double teeth 17.
After the bolt and the ratchet wheel are combined, the eight rectangular bulges surrounding the bolt are just placed into the guide groove of the guide rail, and the bevel double teeth at the front end of the guide rail correspond to the bevel teeth on the ratchet wheel; the ratchet wheel starts to slide after the bolt is pulled, once the ratchet wheel is separated from the moving groove, the ratchet wheel slightly rotates when sliding into the edge, when the bolt is released and pulled, the contact of the ratchet wheel teeth and the guide edge causes more rotation and slides inwards until the ratchet wheel teeth are meshed with the bottoms of the long teeth of the inclined double teeth of the guide rail, and then the bolt retracts and is pulled out of the jack; when the ratchet wheel is pulled again, the bevel teeth on the ratchet wheel continuously rotate, the bevel teeth slide to the tail end along the moving groove of the guide rail, and the corresponding latch extends out of the front cover and enters the jack.
