Abstract

The utility model discloses an emergent handle structure, including installing the support on the hatch door, inserting the bolt of establishing in the support, be equipped with on the hatch door frame can with bolt complex jack, be equipped with on the support can with bolt complex pinhole, the pinhole is equipped with the opening. In emergency, the stability and the precision of operator's action are not high, and it becomes a difficulty to extract the bolt from the support, and for this reason, this design sets up the opening with the pinhole. The existence of the notch enables the pin hole to be enlarged even if the pulling-out direction of the pin is large in axial deviation from the pin hole, and the pin can be smoothly pulled out from the pin hole. Therefore, the operator can open the cabin door quickly to strive for time for escape.

Detailed Description

With reference to fig. 1 and 2, an emergency handle structure includes a support 20 mounted on a door 10, and a bolt 30 inserted into the support, wherein a receptacle capable of being engaged with the bolt is provided on a door frame 40, a pin hole 21 capable of being engaged with the bolt is provided on the support, and the pin hole is provided with a gap 22.

In an emergency, the operator pulls out the plug 30 from the holder 20, and even if the axial deviation between the pull-out direction of the plug and the pin hole 21 is large, the plug can enlarge the pin hole due to the notch 22, and can further pull out the plug smoothly from the pin hole.

As shown in fig. 3, the support 20 includes a bottom plate 23, and a left wing plate 24 and a right wing plate 25 disposed at both sides of the bottom plate, the bottom plate is connected to the pod door 10, the pin holes 21 are disposed on the left wing plate and the right wing plate, and the slits 22 are disposed on the left wing plate and the right wing plate. As a modification, the support 20 is formed by bending a single plate, that is, the left wing plate 24 and the right wing plate 25 are formed by bending. In the above-described structure of the bracket, since the left wing plate 24 and the right wing plate 25 are thin plate-shaped, when the plug 30 is largely deviated from the axial direction of the pin hole 21 in the drawing direction, the plug can easily and smoothly draw out the pin hole by enlarging the pin hole.

The hatch 10 is provided with a recess 11 in which the seat 20 fits, the side wall of the recess being provided with a through hole corresponding to the pin hole 21 in the seat, i.e. the through hole and the pin hole are arranged coaxially. And the bottom plate 23 of the support is arranged at the bottom of the concave structure through a threaded connector, so that the support is fixed.

The surface of the cabin door frame 40 is provided with a groove, the side wall of the groove is provided with a through hole, the bolt 30 is inserted into the through hole on the side wall of the groove from the groove, passes through the through hole on the side wall of the concave structure and is matched into the pin hole 21 of the support 20.

The outer surface of the plug pin 30 is provided with a paint layer, the plug pin is in clearance fit with the pin hole 21, and the paint layer is in interference fit with the pin hole. When the surface of the bolt is not painted, the bolt is in clearance fit with the pin hole; when the surface of the bolt is sprayed with a layer of paint, the bolt is in interference fit with the pin hole. By the design, the bolt and the pin hole can be stably matched under normal conditions; in an emergency, the plug pin can be smoothly pulled out of the pin hole.

As a modification, as shown in figure 2, a bush 26 is provided in the pin bore 21, extending to a through hole in the side wall of the recess, in which bush a spigot 30 is fitted. Therefore, when the surface of the bolt is not sprayed with paint, the bolt is in clearance fit with the bush; when the surface of the plug pin is sprayed with a layer of paint, the plug pin is in interference fit with the bushing.

Referring to fig. 4, the latch 30 is connected to a handle 32 by a connecting piece 31, the handle having a closed opening 33 into which an operator's fingers can extend to grasp the handle and smoothly pull out the latch. The connecting piece is welded with the bolt and the connecting piece is welded with the handle. Wherein, the handle is formed by bending a strip-shaped piece.

The connecting piece 31 is bent, and the handle 32 protrudes outwards, i.e. towards the outside of the recess of the door frame, or protrudes towards the operator from the recess of the door frame, so that the operator can hold the handle quickly.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
