Detailed Description
As shown in figures 1-10, the invention discloses a pedal type door locking device, which comprises a lock catch part fixed on a wall and a mechanical transmission device arranged on a door, wherein a pressing spring 7 is arranged between an upper plate 4 and a lower plate 5 of a pedal, the upper plate 4 of the pedal is connected with a metal pull rope 3, the metal pull rope 3 spans across a steering pulley 2, passes through a rear cover 12, then passes through a spring 13, passes through a hole in the middle of a ratchet wheel 10, and finally is connected with a bolt 9. 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 the spring 13 provides an elastic force between the right side of the ratchet 10 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 bolt 9 is a hollow cylindrical structure, 8 square projections 18 are arranged around the bolt, and eight triangular projections formed by the tooth-shaped structure at the front part are indexing claws 14; the front end of the ratchet wheel 10 comprises four inclined plane tooth-shaped structures which are sliding claws 15, and the thinner head part 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 bevel teeth of the ratchet wheel to pass through is arranged between the bevel double teeth 17.
The structure and the motion principle of the bolt, the ratchet wheel and the guide rail of the invention are completely the same as those of the existing pressing type elastic ball pen, and the working principle is described simply here: 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.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
