Description
Technical field
The utility model is related to a kind of dynamic environmental test equipment, and in particular to a kind of door latch structure of temperature control box.
Background technology
Three synthesis oscillation pilot systems are to enter the equipment of trip temperature and vibration integrated dynamic environmental test to product, be for
Electronic product is investigated during transport, storage, use because of influence that vibration and temperature change are produced to it.
Traditional three synthesis oscillation pilot systems, including temperature control box and electric vibration table, temperature control box have sealing due to its door
It is required that, therefore need to close the door lock of pulling force with certain door.
Conventional temperature control box door lock is general using finished product door locks such as the mechanical packing handles or the quick hasp of adjustable type of finished product.
In industrial hardware enterprise, although door lock can also require to make corresponding change according to user（For example：Coupling mechanism force, locking pattern, lock
Volume etc.）, but be also only that micromodification is dynamic in terms of installing room, it is impossible to accomplish personalized customization（It can accomplish also to pay big
Cost）.
The content of the invention
The utility model purpose is to provide a kind of temperature control box rotation lock compact form door lock, meets what temperature control box was proposed to door lock
There is certain closure pulling force and installation site is arbitrarily required.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of temperature control box rotation lock compact form door lock,
Including lock core and dead bolt；
The lock core includes lock housing, steel ball and keeps set, rotational lock bushing and at least three steel balls；The lock housing is fixed

At least three steel ball providing holes are offered in the circumference of set, steel ball is arranged in steel ball providing holes, the rotational lock bushing with
Steel ball keeps the concentric outside for being sheathed on steel ball holding set of set, and rotational lock bushing is rotated relative to lock housing and set, the rotation
Correspond to each steel ball on twist lock clamping hub inwall and be provided with the contention effect cambered surface for acting on steel ball, these contention effect cambered surfaces are around rotation
The axial line of twist lock clamping hub is rotationally symmetrical to be set；On the radial section of rotational lock bushing, each contention effect cambered surface
One end to the distance of the axial line of rotational lock bushing is more than its other end to the distance in the axle center of rotational lock bushing, is made with this
Steel ball, which has, extends out two working conditions of release and interior crowded locking；
The dead bolt is arranged on the chamber door of temperature control box or casing corresponding to lock core, and dead bolt includes a dead bolt post, an aligning
Seat and an aligning spring；The aligning seat is fixed, and the dead bolt post is set in aligning seat towards lock core, the dead bolt post root
It is slidably matched between aligning seat with sphere, the aligning spring is a volute spring, and it is sheathed on the root of dead bolt post, and its is big
Head end is pressed on aligning seat, and small head end is fastened on dead bolt post periphery；The head of the dead bolt post and the steel ball of lock core are protected
Hold and cover correspondence nested arrangements, the head of dead bolt post is provided with the locking inclined-plane coordinated with steel ball, locking for dead bolt post is made with this
The radial dimension of inclined-plane towards the end of dead bolt post head side is more than it and is locking footpath of the inclined-plane towards the end of dead bolt post root
To size；
The head of the dead bolt post of the dead bolt is embedded in the steel ball of the lock core and kept in set, when the rotation of rotational lock bushing,
Steel ball is moved along contention effect cambered surface, steel ball is in interior crowded lock-out state, steel ball coordinates with the locking inclined-plane on dead bolt post will
Dead bolt post clamping, so as to constitute the locking state of door lock；When rotational lock bushing is reversely rotated, steel ball is moved back along contention effect cambered surface
Return, switch to steel ball and extend out releasing orientation, so as to constitute the released state of door lock.
In such scheme, the dead bolt post includes a cylinder, a sphere piece and a bolt, and the cylinder root is located at tune
The side of heart seat, and sphere piece is located at the opposite side of aligning seat, bolt is from sphere piece through aligning seat and cylinder root screw thread
The first sphere of indent is set on connection fastening, the cylinder root, and with the second sphere and the first ball of an evagination on aligning seat
Face is slidably matched, towards the 3rd sphere that the side of aligning seat is an evagination on the sphere piece, with the of an indent on aligning seat
Four spheres are slidably matched with the 3rd sphere.
Further, the cylinder is formed by a root body and header body two parts threaded connection, and root body is provided with use
In the taper surface of the small head end cutting ferrule of aligning spring.
In such scheme, two wire digging lines are wound with the rotational lock bushing periphery, two wire digging lines are around to phase
Instead, steel wire draws one end of shell to rotate against Locking bushing and fixed, and the other end draws lock housing and is used as operating portion.
The utility model has advantages below：
