Abstract
The utility model belongs to accessory equipment of a civil aviation airplane, and in particular, the utility model is a carpet compression bar for the airstairs. According to the design scheme provided by the utility model, one end of a sleeve bar is connected with a fixing sleeve whose inner portion is provided with a movable expansion bar; the space between the end portion of the expansion bar and the fixing sleeve is provided with a spring. The outer end of the expansion bar and the end portion of the sleeve bar are respectively connected with a fixing socket. The wall of the fixing sleeve is provided with a guiding slot; the expansion bar is provided with a guiding pin whose outer end is positioned in the guiding slot. The compression bar has expanding and shrinking functions and is convenient for the installation, the assembly and the disassembly of the carpet compression bar.
Description
Technical field
The utility model belongs to a kind of accessory equipment of aircarrier aircraft, the carpet depression bar on specifically a kind of elevator.
Background technology
Aircarrier aircraft is when on-board and off-board, a kind of elevator of movable type is used in the capital, this elevator generally is installed on the civil aviaton's special-use vehicle that is referred to as ladder vehicle, after aircraft reaches the airport, this ladder vehicle is opened the objective door place to aircraft, under the effect of cylinder piston, elevator is given rise to certain height, so that the passenger goes on or off the plane.On elevator, generally all lay carpet,, but just lay when using at every turn because this carpet is not for good and all to be laid on the elevator, with just accepting later, therefore can only be simply to lie on the elevator,, need utilize a kind of removable depression bar that it is pushed down for avoiding loosening and landing.
In the prior art, the structure of this depression bar is relatively backward, usually adopt the through-hole type permanent seat at the carpet two ends, be fixed on the plane at ladder two ends, depression bar is a straight-bar, during installation, one end of depression bar is put into the depression bar seat earlier, and till extending through certain distance and can inserting the depression bar seat to the other end, at this moment with depression bar other end aligning depression bar seat hole, depression bar seat, fixedly carpet are inserted in the depression bar translation.
The defective of this mode is 1, because the carpet depression bar is less with the carpet fixed range, or the carpet depression bar is tighter with the permanent seat assemblage gap, the installation inconvenience.If 2 carpet depression bars and permanent seat assemblage gap be pine, or distance is bigger between carpet and the depression bar, and vehicle is when travelling or turn, and depression bar comes off easily.3, this depression bar is cumbersome when installing with use.
Summary of the invention
The purpose of this utility model is to design a kind of carpet depression bar of aircraft ladder vehicle, and this depression bar has Telescopic, can make things convenient for the installation and removal of carpet depression bar.
According to design plan provided by the utility model, be connected and fixed cover at an end of loop bar, transportable expansion link is arranged in fixed cover, between the end of expansion link and fixed cover, spring is set.Be connected and fixed seat respectively in the outer end of expansion link and the end of loop bar.
Offer guide groove on the wall of fixed cover, guide finger is installed on expansion link, the outer end of this guide finger is positioned at guide groove.As another kind guiding form, can on expansion link, offer guide groove, can embed guide finger in this guide groove the inwall setting of fixed cover.
The inner sealing of fixed cover is placed spring between the inwall bottom of expansion link and fixed cover.
The utility model has the advantages that: because the carpet depression bar has Telescopic,, reduced the time of installation and removal, improved effect so installation and removal are very convenient; Secondly, because the carpet depression bar can stretch, when time spent not can be taken in the fixed cover, vehicle is when travelling or turn, and the carpet depression bar can not come off.

The specific embodiment
As shown in the figure: be connected and fixed cover 5 at an end of loop bar 7, transportable expansion link 3 is arranged in fixed cover 5, between the end of expansion link 3 and fixed cover 5, spring 6 is set.During use, expansion link 3 is pressed in the fixed cover 5, being pressed in needs on the fixing carpet again, loosen expansion link 3 then, under the effect of spring 6, expansion link 3 is protruding, the end of expansion link 3 and the end of loop bar 7 are withstood on the side plate of elevator both sides respectively tightly, carpet is fixed.
Offer guide groove 8 on the wall of fixed cover 5, guide finger 4 is installed on expansion link 3, the outer end of this guide finger 4 is positioned at guide groove 8.Guide finger 4 play the guiding role on the one hand with guide groove 8, avoids phenomenons such as expansion link 3 twists when stretching out; Also play position-limiting action simultaneously, in order to avoid expansion link 3 breaks away from fixed cover 5, the Stroke Control that makes expansion link 3 is in certain scope.
As guiding and spacing another kind of version, also can on expansion link 3, offer guide groove, can embed guide finger in this guide groove the inwall setting of fixed cover 5.The effect of this structure and last kind are similar, but because guide groove is opened on the expansion link, comparatively speaking, the outer wall of fixed cover can avoid the above-mentioned guide finger that exposes to collude brokenly problems such as carpet with regard to smoother.
For making whole depression bar can obtain good location, can utilize screw 1 to be connected and fixed seat 2 respectively in the outer end of expansion link 3 and the end of loop bar 7 with fixing.
The inner sealing of fixed cover 5 is placed spring 6 between the inwall bottom of expansion link 3 and fixed cover 5, this structure helps the location of spring, need not utilize other member to come retainer spring again.
