Between connect the bindiny mechanism used or device.
Background technology
Now, when carrying out corner connection between the plank and plank of plate fitment cabinet, screw is mostly added using connecting corner yard
Form carries out assembly and connection；Or group is carried out using the plank connection component being made of eccentric wheel, screw connection bar, embedded nut
Load connects.In actual use, there is also following deficiencies for these corner connectors：First, it is carried out using corner brace and screw
Be fixedly connected, corner brace and screw terminal be all apparent in it is outer, leverage connected between furniture item or plank it is clean and tidy with it is beautiful
It sees；Secondly, assembly and connection is carried out using corner brace and screw, cannot achieve multiple repeated disassembled and assembled, in other words, repeatedly it is upper it is secondary with
After dismounting, screw hole position is easy to be stretched or wear, and causes to connect insecure.In addition, using eccentric wheel, screw connection bar,
Embedded nut carries out assembly and connection, since eccentric wheel is to lock the screw terminal of screw connection bar by rotating a certain angle
, however whether eccentric wheel lock obtains and fastens, and has much relations with the damping design at eccentric wheel rotation, it is existing by eccentric wheel,
In the plank connection component that screw connection bar, embedded nut are constituted, significant portion damping is not fine, is being actually used
In, the phenomenon that being all easy to get loose, lock loosely.Therefore, all there is also larger deficiencies in the prior art scheme, very
It is necessary to carry out exploitation again and design to these connection components, connected between furniture cabinet or plank and plank with preferably meeting
The needs of assembling.
Utility model content
Utility model aims to solve the above problem and deficiency, provide it is a kind of it is easy to connect, will not loosen, connect
It is solid and reliable, it can assemble and disassemble repeatedly, will not damage or be corrupted to the quality of plank, and simple in structure, realization is easy, production cost
Rationally, without the low concealed connecting device of dedicated fluting apparatus, application cost.
What the technical solution of the utility model was realized in：A kind of concealed connecting device, feature are to include peace
Pedestal, vertical bolt, vertical gear, transverse gear and connector are filled, wherein the vertical bolt is rotationally vertically installed on
In installation pedestal, the upper end of the connector and vertical bolt is mutually screwed on, and the vertical gear is connected with the bottom end of vertical bolt
It connects；The transverse gear is rotatably installed in installation pedestal and is meshed together with vertical gear, the one of transverse gear
Tool operation port is additionally provided on end.
In order to further optimize the utility model installation pedestal structure reasonability and science, make more easily to process
With production, the installation pedestal includes the left fixed part with mounting hole, the right fixed part with mounting hole and chamber resettling, described perpendicular
It is passed through into chamber resettling to the lower end of bolt from the top surface of installation pedestal, the vertical gear is mounted in chamber resettling
Vertical bolt lower end on；The transverse gear is installed in chamber resettling and is meshed with vertical gear；In chamber resettling
Handle hole corresponding with the tool operation port on transverse gear is additionally provided on surface.
Anti-loose performance after being connected in order to further enhance the utility model, keeps locking very secured, never occurs
The phenomenon that loosening is located in the chamber resettling on the other end of transverse gear and is additionally provided with clutch, and the clutch is by grasping
Control lever, preceding clutch part, rear clutch part, spring are constituted.
In order to optimize the assembling structure of clutch, make its structure is more simple, assembly is more convenient, processing more
It is easy, the suit hole of connectivitv tool operation port is equipped in the transverse gear, the control lever is connected one with rear clutch part
It rises, which is set in suit hole and is formed with manipulation end in tool operation port, and the preceding clutch part is set to
In the other end face of transverse gear；It is additionally provided with limit connecting pole in clutch part after described, band is additionally provided in the chamber resettling
The mounting post in hole is limited, the limit connecting pole of the rear clutch part is socketed on the restriction hole of mounting post, one end of the spring
It is sleeved in mounting post, the other end overhead of the spring is on the back side of rear clutch part, so that rear clutch part is nibbled with preceding clutch part
Unify.
The beneficial effects of the utility model：Due to using by installation pedestal, vertical bolt, vertical gear, transverse gear and
The concealed connecting device that connector is constituted, in application, installation pedestal and the vertical bolt being installed on it, vertical gear, transverse direction
Gear, which is hidden to be installed on one block of plank together, to be provided in installation cavity groove, and by being locked in screw to plank from mounting hole, real
Now installation pedestal is fixed on the plank, connector is installed on another block of plank；When two plates assemble, by one block of plank
It is connected to each other with another block of plate, uses operation instrument（Such as Allen key, screwdriver）The tool operation port on transverse gear is rotated, is enabled
Transverse gear rotates, and then drives the rotation of vertical gear, and vertical bolt is made to rotate, vertical bolt and connector be screwed on together, from
And mutually assembling is fixedly connected between realizing two blocks of planks.Bindiny mechanism as the utility model designs so that vertical bolt
The problem of being very firm with being screwed on for connector, pine will not be returned, revolve not tight, lock loosely, and entire attachment device
It hides and is placed in plank, be effectively guaranteed the clean and tidy and beautiful of plate surface.Reason is among these, transverse gear rotation
It is the rotation in lateral orientation, it is to pass through transverse gear in the rotation in vertical orientation that vertical gear, which drives the rotation of vertical bolt,
It drives the vertical gear to rotate, and then vertical bolt is made to be screwed with connector, virtually between transverse gear and vertical gear
Frictional resistance is formd, and this frictional resistance is longitudinal and laterally staggered formation friction damping force.When external force acts on
When in two plates, the suffered power impact indirectly of installation pedestal, connector, vertical bolt cannot enable vertical bolt perpendicular
To orientation rotation, so as to ensure that being screwed on for vertical bolt and connector will not return pine or fall off.And traditional screw is straight
Formula locking is connect, not crisscross frictional resistance makes its screw under external force, is susceptible to and returns pine, revolves not tight, lock not
Phenomena such as firm, and screw head is exposed at outside, influences the beautiful and clean and tidy of plate surface.The utility model can widely be applied each
Kind plank（Such as wood plank, sheet metal, aluminium plate）Between, the mutual assembly and connection of workpiece and workpiece uses.
