Description

Rotary waterproof button lock

Technical Field

The invention relates to a rotary waterproof button lock, and belongs to the technical field of airplane flap locks.

Background

In order to ensure that airborne equipment on an airplane can be maintained and repaired in time in use, a large number of covers need to be arranged on the surface of the airplane, the covers are divided into quick-release covers and non-quick-release covers according to the use characteristics of the covers, and the whole covers can be opened or closed by simply pressing, screwing or using a simple tool.

At present, the airplane is used for rapidly opening and closing various covers, and the airplane can be mainly divided into a rotary type, namely a screw type, a snap type, a hook tongue type, an integral detachable type and the like from the mechanism principle and the operation mode. The rotary quick-release lock is convenient to apply, small in size and relatively weak in load bearing capacity; the snap-on quick release lock can bear large load, but the operation space and the opening size are large; the hook tongue type quick release lock has good sealing performance and larger bearing capacity, but is only suitable for places with larger wall thickness.

At present, be applied to the connection lock of aerospace operation flap, have bulky, weight is heavy, the operation is unchangeable, handhole door and mouthful frame all need the opening, can't rain-proof shortcoming such as sealed, and lock and open extremely inconveniently, can't satisfy the operation requirement of more and more high-speed military products.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides the rotary waterproof button lock which is simple in structure, convenient and reliable to operate, small in size, light in weight and good in sealing effect.

The technical scheme for solving the technical problems is as follows: a rotary waterproof button lock comprises a lock seat, a driving assembly, a swing arm, a sliding block, a support and a pressure head, wherein one side of the lock seat is provided with a driving jack, the other side of the lock seat is provided with a sliding groove, the driving assembly comprises a shaft shell and a mandril inserted in the shaft shell, the shaft shell is sleeved in the driving jack, the shaft shell is provided with a through groove, the mandril is provided with a pin shaft, the pin shaft extends into the through groove, the mandril below the pin shaft is provided with a spring, and the lock seat is provided with a locking groove matched with the end part of the pin shaft;

the sliding block is arranged in the sliding groove, one end of the swing arm is connected with the shaft shell, and the other end of the swing arm is hinged with one end of the sliding block through a connecting rod; the support is the form of buckling, support one end with the lock seat is articulated, and the middle part is equipped with the guide slot, and the other end is connected the pressure head, be equipped with on the other end of slider and dial the round pin, it extends to dial the round pin in the guide slot.

The invention has the beneficial effects that: the push rod is pressed, a rod head at the end part of the push rod compresses a spring, the push rod moves upwards, the pin shaft moves upwards to be separated from a locking groove on the lock seat, then the shaft shell is rotated, so that a swing arm connected with the shaft shell is driven to swing, a connecting rod hinged with the swing arm converts the rotation action of the swing arm into the linear motion of the slide block in the lock seat, the slide block moves towards the side of the driving assembly, so that a shifting pin is driven to move, the shifting pin drives the support to rotate through a hinged fulcrum of the support and the lock seat, and a pressure head rises along with the upward movement; when the push-button lock needs to be locked, the push rod is pressed, the shaft shell rotates in the opposite direction, the swing arm rotates in the opposite direction, the connecting rod converts the rotation of the swing arm into the linear motion of the sliding block in the lock seat to the direction away from the driving assembly, the shifting pin moves along with the linear motion, the support rotates through the hinged fulcrum, and the pressing head is put down to realize the locking of the push-button lock. The ejector pin is moved up and has been realized that the round pin axle breaks away from the purpose of locking recess rotating shaft shell, the shaft shell exposes the slotted hole of the spanner operation of being convenient for in addition, the rotating shaft shell is convenient and fast more, after button lock locking or unblock, the ejector pin resets under the effect of spring, ejector pin and shaft shell surface parallel and level can not only play sealed slotted hole and play waterproof effect, and to the high-speed aircraft of flying any slotted hole in surface can all influence the security of aircraft flight, the setting of ejector pin has improved the security of aircraft flight.
