The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The present invention will be described in further detail below with reference to specific embodiments and with reference to the attached drawings.

The first embodiment is as follows: as shown in fig. 1 to 3, the manual locking arm applied to the folding door includes a door frame 1, wherein a connecting groove is formed on a side wall of the door frame 1 close to the door body 12, and an edge of the door body 12 can abut against the connecting groove. The fluting 2 of the leading flank of door frame 1, wherein, fluting 2 adopts cuboid structure, all rotates in the fluting 2 to be connected with manual handle, and wherein, manual handle comprises tension bar 3 and locating part 4 jointly, and tension bar 3 and locating part 4 can adopt integrated into one piece to set up, and locating part 4 passes through the pivot with 2 inside walls of fluting to be connected, and tension bar 3 adopts rectangular structure, and the equal fillet of edge of tension bar 3 sets up.

Set up the sliding tray 5 of horizontal direction on the door frame 1, sliding tray 5 intercommunication spread groove and fluting 2 setting, sliding

block

6 and 5 inside big or small looks adaptations of sliding tray make sliding block 6 can make a round trip to slide in sliding tray 5 inside, and the surface of sliding block 6 and the equal smooth setting of internal surface of sliding tray 5 set up the frictional force between reducible sliding block 6 and the sliding tray 5 like this.

The side wall of the sliding groove 5 is provided with a rectangular groove 7, the rectangular groove 7 is communicated with the inside of the sliding groove 5, and the rectangular groove 7 corresponds to the position of the limiting part 4.

Be provided with slide bar 8 in the rectangular channel 7, the both ends of slide bar 8 weld respectively inside rectangular channel 7, and sliding connection has sliding sleeve 9 on slide bar 8, and the surface of slide bar 8 and the equal smooth setting of internal surface of sliding sleeve 9 set up the frictional force between reducible slide bar 8 and the sliding sleeve 9 like this.

The sliding sleeve 9 is fixedly connected with the side wall of the sliding block 6 in a welding mode, the sliding rod 8 is sleeved with two springs 10, the two springs 10 are respectively located at two ends of the sliding sleeve 9, two ends of each spring 10 are respectively fixedly connected with the sliding sleeve 9 and the sliding block 6 in a welding mode, and after the sliding block 6 slides into the rectangular groove 7, the two springs 10 are in a static state.

One side of the sliding block 6 close to the limiting part 4 is designed with an arc-shaped groove 11, and the arc-shaped groove 11 corresponds to the arc-shaped protrusion 20 of the limiting part 4 when the switch is closed.

The front side wall of the door body 12 is provided with a slot 13, the slot 13 is arranged corresponding to the sliding block 6, and the slot 13 is matched with the sliding block 6 in size, so that the end part of the sliding block 6 can slide into the slot 13. When the arc protrusion 20 is completely separated from the inside of the arc groove 11, the sliding block 6 slides into the sliding groove 5, and when the arc protrusion 20 is completely clamped into the inside of the arc groove 11, the sliding block 6 slides into the slot 13.

The working principle is as follows: after the door body 12 is closed, a user pulls the tension rod 3 downwards by hand, the arc-shaped protrusion 20 extrudes the arc-shaped groove 11 to enable the sliding block 6 to be extruded, the sliding block 6 slides in the sliding groove 5 at the moment, the end part of the sliding block 6 slides into the slot 13 to lock the door body 12 and the door frame 1, when the door body 12 needs to be opened, the tension rod 3 is pulled upwards, the arc-shaped protrusion 20 slowly breaks away from the arc-shaped groove 11 to enable the pressure on the sliding block 6 to be relieved, the sliding block 6 slides into the sliding groove 5 under the elastic action force of the spring 10, and the locking of the door body 12 and the door frame 1 is relieved at the moment.

Example two: on the basis of the above embodiment, the inner side surface of the slot 2 is provided with a first groove 14, the first groove 14 is internally provided with a first magnet block 15, the first magnet block 15 is adhered in the first groove 14 through glue, the front side wall and the rear side wall of the tension rod 3 are both provided with a second groove 16, the second groove 16 is internally provided with a second magnet block 17, the second magnet block 17 is adhered in the second groove 16 through glue, the first magnet block 15 and the second magnet block 17 have opposite magnetism, since the first magnet piece 15 and the second magnet piece 17 are magnetically attracted to each other due to opposite attraction, therefore, set up the magnet piece between fluting 2 and tension bar 3, make tension bar 3 can the actuation in fluting 2, tension bar 3 accomodates comparatively neatly in fluting 2, does not influence folding door and door frame 1's whole pleasing to the eye, also can not appear because the problem that the lock handle overlength leads to the collision.

Example three: on the basis of the above embodiment, the left and right side walls of the tension rod 3 are both provided with the handle grooves 18, and the handle grooves 18 are in a rectangular structure and provided with the handle grooves 18, so that the tension rod 3 can be conveniently pulled.

Example four: on the basis of the above embodiment, the outer side of the tension rod 3 is wrapped with the anti-slip rubber layer 19, the anti-slip rubber layer 19 is bonded on the outer side of the tension rod 3 through glue, and the anti-slip rubber layer 19 is arranged to increase the comfort of hands.

In summary, after the door body is closed, the tension rod is pulled down, the arc-shaped protrusion extrudes the arc-shaped groove, the sliding block is extruded to slide in the sliding groove, the end part of the sliding block slides into the slot, the locking of the door body and the door frame is completed, when the door body needs to be opened, the tension rod is pulled up, the arc-shaped protrusion slowly separates from the arc-shaped groove at the moment, the pressure applied to the sliding block is relieved, the sliding block slides into the sliding groove under the elastic action force of the spring, the locking of the door body and the door frame is relieved at the moment, and the manual locking arm is simple in structure, convenient to operate and low in production cost.

While the present invention has been particularly shown and described with reference to the preferred embodiments, and many methods and approaches to the practice thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
