Description
Technical field
The present invention relates to a kind of cabinet door (window) fast-switching arrangement, particularly a kind of high-speed switch cabinet device that airtight cabinet door is arranged belongs to mechanical structure field.
Background technology
Have in the cabinet design of seal request or electromagnetic shielding requirement at some, the designer is for the cabinet door and cabinet can be combined closely, effectively compression seal bar or shielding strip, adopts bolt to connect usually cabinet door (window) and cabinet are linked together.
But, needing the cabinet door (window) of frequent open and close for some, bolt connects extremely inconvenient, and opening and shutting wastes time and energy, and gives and uses, safeguards, checks, keeps in repair and bring very big inconvenience.
Summary of the invention
The objective of the invention is to design a kind of high-speed switch cabinet device that airtight cabinet door is arranged, make the attended operation of cabinet door and cabinet simple, open and close are rapid, and it is reliable to be tightly connected.
The present invention includes cam handle, bearing pin, cabinet door, cabinet, screw-casing, turnbarrel, hook, pull bar, spring, guide finger, sealing ring; Screw-casing is cap-like structure, its cap shape boss is a hollow circular cylinder, cap shape boss upper edge y direction symmetry in the same way has groove, groove is divided into AB and BC two parts, AB is that spiral section, BC are straightway, turnbarrel also is cap-like structure, and its cap shape boss is a hollow circular cylinder, and the correspondence position of the groove AB section on the cap shape boss of the outside of its cap shape boss and screw-casing has guide finger; Cabinet has ring-shaped groove; The height of turnbarrel is greater than the height of screw-casing, and the cap shape boss external diameter of turnbarrel is consistent with the cap shape boss internal diameter of screw-casing,
The mutual connection relationship of each part is described: screw-casing is fixed on cabinet door inboard, pull bar passes turnbarrel, spring, screw-casing, cabinet from left to right successively and is connected with handle with bearing pin behind the door, pull bar withstands turnbarrel at left end with the shaft shoulder, the right-hand member external cylindrical surface of turnbarrel cooperates the location with the left end inner cylinder face of screw-casing, hook is socketed in the left end of turnbarrel, and circumferentially fixing on the shaft shoulder of the left side of turnbarrel, thereby make hook and turnbarrel relative fixed can advance and retreat synchronously and rotate.Sealing ring is installed in the ring-shaped groove of cabinet.
Each part interacts and describes: the cabinet door is under open mode, the cam of cam handle is in low level, spring is in little compressive state, hook is in transverse presentation and avoids cabinet, when needing to close the Over-The-Counter door, cabinet door and cabinet are closed up, pull cam handle, toward high-order motion, the pulling pull bar moves right cam from low level, and pull bar promotes turnbarrel and hook moves right, the guide finger of turnbarrel moves along the gathering sill of screw-casing, the guide finger of turnbarrel is along two helicla flute incisions of screw-casing, and turnbarrel cooperates the location with external cylindrical surface with the inner cylinder face of screw-casing, after this angle can make hook forward the cabinet edge to, when cam handle continues rotation, the guide finger of turnbarrel moves along the BC section straight-line guidance groove of screw-casing, hook axially-movable tension cabinet and cabinet door, the spring of turnbarrel compression simultaneously; Under the tension force effect of spring, all parts be in tensioning state and can the pine not spacious.
The axial tightening force that cam handle produces is very big, and cabinet door and cabinet can tightly be fitted airtight.Because the cam lift angle is less than angle of friction,, can rests on any position and can oneself not rotate so cam handle has self-locking performance.
The cabinet door is under open mode, the cam of cam handle is in low level, spring is in compressive state, hook is in transverse presentation, when needing to close the Over-The-Counter door, cabinet door and cabinet are closed up, pull cam handle, cam moves toward high-order from low level, the pulling pull bar moves right, and pull bar promotes turnbarrel and hook moves right, and the guide finger of turnbarrel moves along the gathering sill of screw-casing, in the AB section, make turnbarrel and thereon the hook of being connected rotates to an angle when moving right, after this angle can make hook forward the cabinet edge to, when cam handle continuation rotation, the guide finger of turnbarrel moved along the BC section straight-line guidance groove of screw-casing, hook axially-movable tension cabinet and cabinet door, the spring of turnbarrel compression simultaneously.Because the axial tightening force that cam handle rotation produces is very big, so that cabinet door and cabinet can tightly be fitted is airtight.Because the cam lift angle is less than angle of friction,, can rests on any position and can oneself not rotate so cam handle has self-locking performance.
When opening the door, pull cam handle, toward the low level motion, under the spring force effect, turnbarrel, hook, pull bar are to left movement from high-order for cam, at guide finger when CB straight-line guidance section is moved, cabinet door and cabinet are unclamped in the hook axially-movable, and when BA spirally-guided section was moved, hook is angle of rotation when continuing to unclamp at guide finger, make hook get around the cabinet edge, energy and cabinet door are outwards left together.
Beneficial effect:
1. simple to operate, open and close are rapid.Only need to rotate the open and close that several handles can be realized the cabinet door, satisfy the demand of the frequent open and close cabinet of some equipment door;
2. it is reliable to be tightly connected.Handle rotates cam is rotated together, and cam rotation drive axle rotates simultaneously and stretches.It is very big that handle drives cam torque, is converted into the powerful axial tension of axle, and cabinet door and cabinet are linked together reliably, compresses sealing.
3. oppositely self-locking.Can only be that cam rotation drive shaft extension contracts, and the pulling force of axle can not drive cam rotation, thereby make handle can rest on the optional position.
4. compact conformation.Fast-switching arrangement delicate structure, volume are little, arrangement convenience.
5. flexible configuration.The quantity of fast-switching arrangement can be determined according to the size of sealed door.
