Description

Novel lock mechanism

Technical Field

The utility model belongs to the technical field of mechanical design, concretely relates to novel latch mechanism.

Background

In daily production and life, structural forms of hatches and flaps and the like which need to be opened and closed frequently exist in a plurality of products, such as airplanes, ships, automobiles and the like, and a set of reliable locking and unlocking mechanism is usually needed to ensure that the hatches and flaps can be opened and closed conveniently.

The existing lock mechanisms can be generally divided into two types from the structural form and principle, namely a lock wheel/lock hook type, a lock bolt/lock ring type. The two structural forms have advantages and disadvantages respectively: the latch/lock ring type has the disadvantages that the travel of the pull rod is long when the lock is unlocked, the lock is easy to be locked on an object moving at high speed due to the deformation of the cabin door, and the emergency separation and release of the cabin door are not facilitated, and the latch/lock ring type has the advantages that the processing technology and the assembly are relatively simple, and the use and the maintenance are convenient; the locking wheel/locking hook type is characterized by easy locking and unlocking, small operating force, and the normal and emergency systems can use the same set of transmission mechanism, and the defect is that the abrasion is larger when the design is improper, and the system function is weakened or loses efficacy. For some lock mechanisms that need to be used in high speed motion and vibration environments, the general requirements of the design are that the lock mechanism will not automatically unlock under various normal use conditions, the lock is firm, the unlocking and locking operations are simple, easy and rapid, and all locks must be synchronized and coordinated. Therefore, it is important to design a simple, safe, and reliable lock mechanism for use in the construction of these hatches and flaps.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model aims to provide a novel lock mechanism.

The utility model provides a novel latch mechanism, includes the lock shell, be equipped with lock rocking arm, latch hook and the rocking arm that resets on the lock shell, it is articulated through the lock connecting rod between lock rocking arm and the latch hook, be equipped with on the latch hook and dial the piece, dial the piece and locate the lower extreme that resets the rocking arm, and with the contact of the rocking arm that resets, be equipped with the spring on the rocking arm that resets, lock rocking arm, latch hook and the rocking arm that resets all articulate on the lock shell, latch hook and lock rocking arm all expose outside the lock shell, the operation of being convenient for.

For convenience of operation, the other end of the lock rocker arm is connected to a lock pull rod, and the driving force of the lock pull rod can be set as a motor or can be operated by manpower.

In order to facilitate the connection of the lock shell and the mounting of the lock shell on the movable hatch or the fixed opening frame structure, the lock shell is provided with screws and the lock pin is correspondingly mounted on the other fixed opening frame structure or the movable hatch.

The utility model relates to a novel latch mechanism compares with prior art, and its beneficial effect lies in: the utility model discloses simple structure, the motion of lock mechanism global design is reliable, can satisfy the requirement of locking of hatch door, flap in high-speed motion and vibration environment, and the auto-lock ability requirement when satisfying lock system locking does not produce the automatic condition of unblanking because of the accident, improves the reliability of locking.

fig. 3 is a schematic structural view of the novel lock mechanism of the present invention during unlocking;

fig. 4 is the utility model relates to a novel latch mechanism's spatial structure schematic diagram.

Shown in the figure, the lock comprises a lock shell 1, a lock rocker 2, a lock connecting rod 3, a reset rocker 4, a spring 5, a toggle piece 6, a latch hook 7, a latch pin 8, a screw 9 and a lock pull rod 10.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following examples, which are set forth only for the purposes of explanation and are not intended to limit the scope of the present invention.

As shown in fig. 1-4, a novel latch mechanism, including lock shell 1, be equipped with lock rocking arm 2, latch hook 7 and the rocking arm 4 that resets on the lock shell 1, it is articulated through lock connecting rod 3 between lock rocking arm 2 and the latch hook 7, be equipped with on the latch hook 7 and dial piece 6, dial piece 6 locates the lower extreme of rocking arm 4 that resets, and with the contact of rocking arm 4 that resets, be equipped with spring 5 on the rocking arm 4 that resets, lock rocking arm 2, latch hook 7 and the rocking arm 4 that resets all articulate on lock shell 1, latch hook 7 and lock rocking arm 2 all expose outside lock shell 1, the operation of being convenient for.

For the convenience of operation, the other end of the lock rocker arm 2 is connected to a lock pull rod 10, and the driving force of the lock pull rod 10 can be a motor or can be operated by manpower.

In order to facilitate the connection of the lock housing 1 and the mounting of the lock housing 1 on a movable hatch or a fixed opening frame structure, said lock housing 1 is provided with screws 9 and the locking pin 8 is correspondingly mounted on another fixed opening frame structure or a movable hatch.

The utility model discloses a realize through following mode: the locking and unlocking functions are realized by operating the rocker arm 2 to rotate and rotating the lock hook 7, after locking, a mechanism consisting of the rocker arm 2, the lock connecting rod 3 and the lock hook 7 is at a motion dead point, so that the self-locking performance of the mechanism can be ensured, and when the lock hook 7 slightly rotates in the unlocking direction due to airplane vibration or other reasons, the reset rocker arm 4 acts on the lock hook 7 through the shifting piece 6, so that the lock hook 7 has a torque in the locking direction, and the lock is ensured to be always in the self-locking state. When the lock is unlocked, the lock pull rod 10 is operated to enable the lock rocker arm 2 to rotate and drive the lock hook 7 to rotate towards the unlocking direction, when the lock hook 7 rotates to a certain angle, the torque of the reset rocker arm 4 to the lock hook 7 is changed into the torque in the unlocking direction, and at the moment, the lock can be smoothly released to realize the unlocking.

The utility model discloses simple structure, the motion of lock mechanism global design is reliable, can satisfy the requirement of locking of hatch door, flap in high-speed motion and vibration environment, and the auto-lock ability requirement when satisfying lock system locking does not produce the automatic condition of unblanking because of the accident, improves the reliability of locking.

The protection scope of the present invention is not limited to the technical solution disclosed in the specific embodiment, and all the modifications, equivalent replacements, improvements, etc. made by the technical entity of the present invention to the above embodiments all fall into the protection scope of the present invention.
