Detailed ways

The specific structure and locking and unlocking process of the present utility model will be further elaborated below in conjunction with the accompanying drawings.

Specific embodiment one, see accompanying drawing 1-3 shows, a kind of children's trailer, is arranged on described trailer frame 1 by trailer frame 1, the side wheel 2 that is respectively arranged under the two sides of described trailer frame 1. The towbar 3 at the front is composed of a shielding body arranged on the trailer frame 1, and the shielding body is not shown in each accompanying drawing. The trailer frame 1 is composed of a chassis 4, which is arranged on the chassis 4 The side brackets 5 above both sides are composed of a cross bar 6 connected between the side brackets 5 on both sides. The base frame 4 is provided with a seat, and the side brackets 5 on each side are provided with a door. Frame 8, the door frame 8 and the side bracket 5 are rotatably connected through the rotating shaft 19, the rotation connection position of the door frame 8 and the side bracket 5 is located at the front part of the side bracket 5, and the rotation The axis line of the shaft 19 is perpendicular to the horizontal plane, and the rear portion of the side support 5 has a strut 7, and the strut 7 is inclined backward, and the angle between the length direction of the rod and the horizontal plane is 75 degrees. A locking mechanism 9 is provided between the door frame 8 and the pole 7, and the locking mechanism 9 includes a locking element 10 arranged in the middle of the pole 7, arranged on the door frame 8 and positioned at The lock seat 11 corresponding to the locking element 10 is shown in accompanying drawings 5 and 6, the lock tongue 12 is slidably provided on the lock seat 11, and the lock seat 11 and the An elastic piece 13 is arranged between the deadbolt 12, and the elastic piece 13 provides a restoring force for the deadbolt 12. The elastic piece 13 described in this embodiment is a compression spring, and the right side of the deadbolt 12 The part has a protrusion 14, and the locking element 10 is provided with a groove 15 matching the protrusion 14. The locking mechanism 9 has a locked state and an unlocked state. When the locking mechanism 9 is in the locked state , the bump 14 is inserted into the groove 15, the door frame 8 is in a closed state, and the door frame 8 is fixed to the pole 7; when the locking mechanism 9 is in In the unlocked state, the projection 14 is separated from the groove 15, the door frame 8 is separated from the pole 7, the door frame 8 is in an open state, and the door frame 8 can be Rotate relative to the side bracket 5.
