Description

Lining plate fixing support for mounting on fuselage bulkhead Technical Field The utility model relates to the technical field of aircraft maintenance, in particular to a lining plate fixing support for being installed on a fuselage bulkhead. Background In the process of refitting a passenger plane into a cargo plane, a lining plate needs to be installed on a bulkhead in a plane body, and when the lining plate is installed on the bulkhead, the bulkhead and the lining plate need to be connected through a fixed bracket, but due to the fact that different aircraft models are provided with step pits on individual plane body bulkhead, if the fixed bracket is directly installed at the step pits, a gap is reserved between rivet holes in the step pits and the fixed bracket, and the connection between the fixed bracket and the bulkhead is unstable. Disclosure of utility model The utility model aims to provide a lining board fixing bracket for being installed on a bulkhead of a fuselage, which can firmly connect the fixing bracket to the bulkhead, thereby improving the connection stability of the bulkhead and the lining board. In order to solve the technical problems, the utility model adopts the following scheme: The utility model provides a welt fixed bolster for installing on fuselage bulkhead, is including being used for connecting the connecting plate on bulkhead and welt respectively, runs through on the connecting plate and is equipped with the rivet hole, be equipped with the depressed filling part of step that is used for filling on the bulkhead on the terminal surface before the connecting plate, the shape thickness of filling part is the same with the sunken shape degree of depth of step. The packing structure has the effect that the connecting plate can be tightly attached to the bulkhead through the arrangement of the packing part, so that the connecting plate is firmly connected with the bulkhead. Furthermore, the connecting plate is in a long straight plate shape, the connecting plate is provided with an inclined plate which is obliquely arranged with the connecting plate, and the inclined plate and the connecting plate are positioned in the same plane. The function is that, through the setting of swash plate, can strengthen the joint strength between swash plate and the bulkhead. Further, the swash plate is located the right side of terminal surface before the connecting plate, and terminal surface left side tip is equipped with the left flange that is used for setting up the rivet hole before the connecting plate. Further, the sloping plate is positioned on the upper side of the front end surface of the connecting plate, the filling part is positioned on the lower side of the front end surface of the connecting plate, and the lower end of the filling part is provided with a lower convex plate for setting rivet holes. Further, the lower convex plate comprises a first-stage lower convex plate and a second-stage lower convex plate, and the distance between the second-stage lower convex plate and the upper end of the connecting plate is larger than the distance between the first-stage lower convex plate and the upper end of the connecting plate. Through the setting of left flange, one-level lower flange, second grade lower flange, can set up the rivet in the edge of connecting plate, increased the setting range of rivet, strengthened the joint strength between connecting plate and the bulkhead. Further, an upper convex plate is arranged at the upper end of the left side of the connecting plate. Further, a reinforcing rib is arranged on the rear end face of the connecting plate. The reinforcing rib has the advantages that through the arrangement of the reinforcing rib, the overall structural strength of the connecting plate is enhanced, and the connecting plate is prevented from being bent. Further, the reinforcing rib comprises a main body part positioned at the upper end of the rear end face of the connecting plate, and the main body part extends from the left end to the right end of the rear end face of the connecting plate. Further, the reinforcing rib comprises an inclined reinforcing rib arranged on the rear end face of the inclined plate and a vertical reinforcing rib arranged on the rear end of the upper convex plate, wherein the inclined reinforcing rib and the main reinforcing rib are obliquely arranged, and the vertical reinforcing rib and the main reinforcing rib are vertically arranged. Further, the rivet hole is separated from the reinforcing rib. The utility model has the beneficial effects that: 1. The connecting plate can be tightly attached to the bulkhead by the arrangement of the filling part, so that the connecting plate and the bulkhead are firmly connected; 2. through the setting of swash plate, can strengthen the joint strength between swash plate and the bulkhead.
