Abstract

The utility model belongs to technical field of aerospace, is related to a kind of hatch door fitful wind lock.It is made of lock support, lockwheel, driving lever, lock tongue, block, tension spring bracket, tension spring A, bolt A, tension spring B, shaft, bolt B, lock shaft etc..The bolt A is by lockwheel, lock tongue hinge on lock support, shaft is hinged with lock support by driving lever, the one end tension spring B connects driving lever, the other end connects tension spring bracket, block limitation connection driving lever movement, and the one end tension spring A connects lock tongue, the other end connects lockwheel, bolt A will be worn at various building rotations with shaft, junction bolt A connection, form a relatively complete fitful wind lock set.The utility model proposes fitful wind lock can be bolted on door, hatch door can collide the shaft on doorframe when closing, hook lock hooks automatically, hatch door touches driving lever when closing, hook is locked and is unlocked, the fitful wind latch mechanism is compact, and occupied space is few, effectively hatch door can be lockked, door will not be made to be opened accidentally because of wind load.

Description

A kind of hatch door fitful wind lock

Technical field

The utility model belongs to technical field of aerospace, is related to a kind of hatch door fitful wind lock.

Background technique

Hatch door fitful wind lock, guarantees hatch door opening state, and fitful wind will not make hatch door accidental movement or closing, is locked with fitful wind by cabin Door lock is scheduled on fixed position, and fitful wind lock should be able to resist wind load, lock firm, function automatic lock, again can be smoothly by lower button It unlocks, mechanism is simple, maintains easily.

Hatch door fitful wind lock form is relatively more, has coupling type, traditional latch hook is on door, and lock shaft is on doorframe, and mechanism is more Complexity, this fitful wind lock may be mounted on hatch door, and mechanism is compact, and component is less, and simple and reliable, there are two limit positions in lockwheel It sets, an open position, a close stance, hatch door can be fixedly secured in an accurate location, bear wind load.In addition unlock has Limit, makes the movement travel of driving lever in limited range.

Summary of the invention

The purpose of this utility model is: providing one kind under the premise of meeting structural strength, mechanism is simple, force-transfer characteristic It is good, it maintains easily, the hatch door fitful wind lock of light-weight locking.

The technical solution of the utility model is:

A kind of hatch door fitful wind lock, the fitful wind lock includes lock support 1, lockwheel 2, driving lever 3, lock tongue 4, block 5, tension spring bracket 6, tension spring A7, bolt A8, tension spring B9, shaft 10, bolt B 11, lock shaft 12；The bolt A8 is locking lockwheel 2,4 hinge of lock tongue On bracket 1, shaft 10 is hinged by driving lever 3 and lock support 1, and the one end tension spring B9 connects driving lever 3, and the other end connects tension spring bracket 6, gear The limitation connection driving lever 3 of block 5 moves, and the one end tension spring A7 connects lock tongue 4, and the other end connects lockwheel 2, and bolt A8 rotates various buildings Place's shaft 10 wears, junction bolt A8 connection, forms a relatively complete fitful wind lock set.

Assembled hatch door fitful wind Lock Lee bolt 11 is mounted on hatch door, is moved with hatch door and is touched with the lock shaft 12 on doorframe Spring lock is lived.

It is compact, light-weight that the utility model has the beneficial effect that the utility model proposes a kind of mechanisms, locking jail It leans on, opens smoothly aircraft door and open fitful wind lock, lock shaft encounters idler wheel locking automatically after opening aircraft door, and when opening presses Dynamic driving lever, pushes lock tongue to disengage idler wheel, and tension spring resets movement, and entire lock support is that aluminium alloy adds part, latch mechanism installation On a shelf, arrangement of mechanism is compact, and mechanism is simple, maintains easily.

Detailed description of the invention

Fig. 1 is that the utility model is assembled together fitful wind lock construction schematic diagram；

Fig. 2 is the sectional drawing of the utility model fitful wind lock；

Wherein: 1. lock supports, 2. lockwheels, 3. driving levers, 4. lock tongues, 5. blocks, 6. tension spring brackets, 7. tension spring A, 8. bolt A, 9. tension spring B, 10. shafts, 11. bolt Bs, 12. lock shafts

Specific embodiment

It elaborates with reference to the accompanying drawing to the utility model and embodiment.

Referring to Fig. 1, the utility model fitful wind lock, mainly composition include: by lock support, lockwheel, driving lever, lock tongue, block, The composition such as tension spring bracket, tension spring A, bolt A, tension spring B, shaft, bolt B, lock shaft.

A lock support will be added using aluminium alloy first, the boss for the fixed rotating shaft that there should be driving lever to rotate thereon is fixed The fulcrum of tension spring, and two stiles etc. fixed for lock.

It is reflected in the stroke of tension spring position according to operating force and either on or off position, designs reasonable tension spring, one is driving lever Reset tension spring B, one is tension spring A that lock tongue resets, and tension spring both ends should be equipped with hook.

According to motion principle and simulation analysis, the shape and characteristic point of lock tongue are determined, process lock tongue and idler wheel.

It will be worn at various component rotations with shaft, junction bolt A connection forms one complete group relatively Part, can test whether driving lever is effectively felt, and whether idler wheel and lock tongue can lock, and continuously adjust until satisfied stroke and lock Positioning is set to only.

Lockwheel nest is determined by the diameter of lock shaft, is determined locking by lockwheel motion principle and is unlocked, and driving lever drives turning for idler wheel Dynamic and lock tongue card slot guarantees closing and open position, and tension spring A resets lock tongue movement, and guarantees effectively to be felt with when manual operating, driving lever On also have a reset tension spring B, and in a certain range the movement travel of driving lever limitation, guarantee that lockwheel blocks lock shaft and smoothly de- It opens, entire latch mechanism is fixed on a bracket, is guaranteed stress and is rotated around the axis.
