Abstract
The invention belongs to the technical field of connecting parts of aircraft access panels and particularly relates to a non-falling structure for an access panel lock. In the mechanism, an axial hole (6) is formed in the end face at the lower end of a screw of a bolt (1); one end of a spring (3) is clamped in the hole (6); the other end of the spring (3) is clamped in one of two axial symmetrical short slots (5) in the screw of the bolt (1); two axial symmetrical long slots (2) are formed in the circumferential surfaces of the screw of the bolt (1); two radial symmetrical cross slots (4) are formed between the long slots (2) and the short slots (5); a stopper ring (7) is provided with a hollow circle; the stopper ring (7) is provided with two symmetrical radial bosses pointing to the circle center of the hollow circle in the hollow circle; the diameter of the hollow circle is consistent with that of the screw of the bolt (1); the widths of the long slots (2), the cross slots (4) and the short slots (5) are consistent and are respectively consistent with the widths of the bosses at the middle of the stopper ring (7). The non-falling structure is used for aircraft access panels; the maintainability of the aircraft can be improved.
Description
Technical field
The invention belongs to airplane hatch cover link technical field, particularly relate to a kind of not dropping structure for lid lock.
Background technique
The stressed lid of former aircraft all adopts plate nut, bolt to connect, and this Placement is in lid frequently in opening process, and bolt is easily wrongly installed or lose.Along with improving constantly that home-built aircraft reliability, maintenance are required, in the urgent need to improving this Placement.
Summary of the invention
Goal of the invention of the present invention
The structural type that the present invention locks lock bolt body to airplane hatch cover is improved, under the prerequisite of proof strength index, bolt tail is made to through hole, long and short groove is made on bolt surface, and design one special-shaped spring is as in through hole and short groove, by being used in conjunction with of special-shaped spring, long and short groove, stopper ring is installed on bolt, stopper ring is locked lock body by lid and is connected in lid and realizes the function that do not come off, and after preventing lid and opening, upper lock body is lost or the phenomenon of misloading; Also met the loss of weight requirement of aircraft simultaneously.
Technological scheme of the present invention
A kind of not dropping structure for lid lock, comprise bolt 1, elongated slot 2, spring 3, translot 4, short groove 5 and stopper ring 7, wherein, bolt 1 screw rod lower end surface has axial bore 6, spring 3 one end are stuck in hole 6, the other end is stuck in one of two symmetrical axial short grooves 5 on bolt 1 screw rod, on bolt 1 screw rod circumferential surface, have two symmetrical axial elongated slots 2, between elongated slot 2 and short groove 5, have symmetrical two translots 4 radially, stopper ring 7 is with open circles, stopper ring 7 in open circles with symmetrical two boss radially that point to the open circles center of circle, open circles diameter is consistent with bolt 1 screw diameter, elongated slot 2, the width of translot 4 and short groove 5 is consistent, be all that the middle boss width of stopper ring 7 is consistent.
On stopper ring 7, have lightening grooves.
Beneficial effect of the present invention
A) this structure, for airplane hatch cover, can improve aircraft maintainability;
B) this structural type is simple, and owing to adopting via design at bolt tail, lightweight construction, cost are low;
C) this structure can be used for aircraft double curvature lid;
D) meet model development demand, promote the technological progress of domestic air mail standard piece.
Brief description of the drawings
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is stopper ring schematic diagram;
Fig. 3 is scheme of installation of the present invention.
Embodiment
A kind of not dropping structure for lid lock, comprise bolt 1, elongated slot 2, spring 3, translot 4, short groove 5 and stopper ring 7, wherein, bolt 1 screw rod lower end surface has axial bore 6, spring 3 one end are stuck in hole 6, the other end is stuck in one of two symmetrical axial short grooves 5 on bolt 1 screw rod, on bolt 1 screw rod circumferential surface, have two symmetrical axial elongated slots 2, between elongated slot 2 and short groove 5, have symmetrical two translots 4 radially, stopper ring 7 is with open circles, stopper ring 7 in open circles with symmetrical two boss radially that point to the open circles center of circle, open circles diameter is consistent with bolt 1 screw diameter, elongated slot 2, the width of translot 4 and short groove 5 is consistent, be all that the middle boss width of stopper ring 7 is consistent.
On stopper ring 7, have lightening grooves.
The present invention can be applicable to the bolt of metric system diameter 6mm, 10mm, diameter 1/4in made in Great Britain, 3/8in at present.The material that bolt uses is pressed AMS6382, AMS6349, AMS6322, AMS6325 for alloyed steel 4140 or 8740, or ML40Cr8NiMoA presses GB/T5953, and excessive or too small diameter specifications manufacturability is poor.
One embodiment of the present of invention are as follows: bolt head adopts hexagonal structure in standard, and setting tool adopts standard hex spanner; Inner via design, the mounting spring of adopting of bolt thread; Short groove as shown in Figure 1, starts system from bolt bottom, length 7.5mm, and mounting spring, and as the pilot hole that stopper ring is installed; Elongated slot as shown in Figure 1, with 45 ° of short groove angles, apart from bolt bottom 1.3mm, bolt head 2mm, by translot and short groove together with.
When installation, stopper ring is mounted to spring place by short groove, and spring stretches out bolt surface MAX1.3mm, presses after spring makes stopper ring be pushed into translot and rotates, and makes stopper ring be installed on elongated slot.Under normal working, stopper ring (structure as shown in Figure 2) slides in elongated slot, due to the effect of spring, skids off, thereby reach the effect that bolt does not come off from screw after stopper ring can not rotate from short groove.
Claims (2)
1. the not dropping structure for lid lock, it is characterized in that, this structure comprises bolt (1), elongated slot (2), spring (3), translot (4), short groove (5) and stopper ring (7), wherein, bolt (1) screw rod lower end surface has axial bore (6), spring (3) one end is stuck in hole (6), the other end is stuck in one of symmetrical two axial short grooves (5) on bolt (1) screw rod, on bolt (1) screw rod circumferential surface, have symmetrical two axial elongated slots (2), between elongated slot (2) and short groove (5), have symmetrical two translots (4) radially, stopper ring (7) is with open circles, stopper ring (7) in open circles with symmetrical two boss radially that point to the open circles center of circle, open circles diameter is consistent with bolt (1) screw diameter, elongated slot (2), the width of translot (4) and short groove (5) is consistent, all consistent with the boss width in the middle of stopper ring (7).
2. a kind of not dropping structure for lid lock as described in claim (1), is characterized in that, stopper ring has lightening grooves on (7).
