Description of reference numerals: 1. the door comprises a door frame, 2, a door body, 3, a handle, 4, a locking plate, 5, a return spring, 6, a guide rod, 7 and a U-shaped plate.

Detailed Description

Referring to fig. 1-4, the door locking mechanism of the sheep grabber of the present invention is characterized in that it comprises a handle 3, a locking plate 4 and a return spring 5, wherein the L-shaped locking plate 4 is fixed on the outer side of the upper edge of the door frame 1 provided with the door 2; the bottom end of the handle 3 is hinged on the outer side of the door body 2, and the upper part of the handle 3 corresponds to the opening end of the lock plate 4; a return spring 5 is provided between one side of the handle 3 and the door body 2.

One mounting structure of the return spring 5 is: the lower part of the handle 3 is connected with a U-shaped plate 7, and the bottom end of the U-shaped plate 7 faces to the free end of the door body 2 and is provided with a through hole; one side of the U-shaped plate 7 is connected with the outer side of the handle 3, and the other side of the U-shaped plate 7 is longer than the opposite side and is positioned on the inner side of a vertical column of the door body 2 connected with the handle 3; one end of a guide rod 6 is fixed on the edge of the free end of the door body 2 corresponding to the through hole of the U-shaped plate 7, the other end of the guide rod 6 penetrates through the through hole of the U-shaped plate 7 in a sliding manner (a through hole can be formed in an upright column corresponding to the door body 2 for the guide rod 6 to pass through), the return spring 5 is sleeved on the guide rod 6, and two ends of the return spring 5 are respectively propped between the U-shaped plate 7 and one edge of the free end of the door body 2. The U-shaped plate 7 is long inside and is used for limiting and guiding the handle 3, so that the handle can only swing in the left and right directions (i.e. between two vertical edges of the door body 2).

The guide rod 6 adopts a bolt, and the nut end of the bolt is connected with one side of the free end of the door body 2.

When in use, the door body 2 is in a closed state as shown in fig. 1, and the upper part of the handle 3 is tightly leaned against the opening of the locking plate 4 under the thrust action of the return spring 5; when the door is opened, an operator holds the handle 3 and deflects to the right (see fig. 2) to move out of the lock plate 4, and then opens the door body 2 to the outer side.
