Description
Technical field
The utility model relates to a kind of locking structure that two articles can be linked together, and relates in particular to a kind of Clutch lock fixed structure of energy rapid adjustment angle, and this structure is adapted on the note computer desk especially.
Background technique
Two articles general screw or the bolt of adopting that link together connected, and this Placement can be fixed together two articles, and this Placement is after connection, and the position relation between the two articles just can not change again, promptly is difficult to change angle of swing and direction.But usually need in actual applications to connect fast, fix, can change the locking structure of angle of swing and direction again, as in note computer desk, realize that the change at table (working plate) angle of inclination just needs this locking structure that can change angle of swing and direction.
It also is the linkage structure of a kind of table leg and table the Chinese utility model patent " Foldable notebook computer desk " of ZL200820046461.2 (notification number is CN201200103Y) has disclosed as a patent No., be provided with D type seat in both sides, table back, D type seat inboard is provided with three point arbitrage, the mobile jib two ends are socketed in the three point arbitrage, and the head of strut is located at the bottom of three point arbitrage; The D type seat outside is provided with coupling shaft, coupling shaft is provided with fixed wafer, fixed wafer simultaneously is provided with draw-in groove towards three point arbitrage, the fitting surface of three point arbitrage then is provided with the trip of coupling, also be provided with spring between the two, fixed wafer is provided with spoke shape fluted disc towards the one side of D type seat, is provided with the spoke shape fluted disc of coupling on the fitting surface of D type seat equally; The D type seat outside is provided with lock handle, and both fitting surfaces are a rotation lifting face, and the lock handle inboard is provided with profiled holes and passes the socket of D type seat coupling shaft head; Stressed group of lock handle is changeed the rotation of rear driving coupling shaft, and the rotation lifting face that lock handle is cooperated with D type seat after turning an angle pulls away coupling shaft, and then can make three point arbitrage after coupling shaft obtains to discharge is that the table back side is pressed close in a rotation with the mobile jib.
Though this linkage structure can realize changing the purpose of angle of swing and direction, but its complex structure, and be by lock handle by with D type seat between rotation lifting face cooperate the purpose that realizes pulling away coupling shaft, so the frictional force when the twist-lock handle between lock handle and the D type seat is big, rotate effort and dumb.
In sum, aforementioned locking structure also can be further improved.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of two articles that can make of novel structure to connect fast, fix at above-mentioned prior art present situation, can change the Clutch lock fixed structure of two articles angle of swing and direction again, it has easy to operate advantage simple in structure.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of Clutch lock fixed structure of energy rapid adjustment angle, comprise first link and second link, has the exterior edge face tooth that ring distributes on the exterior edge face of described first link, corresponding, has the interior edge face tooth that ring distributes that is on the interior edge face of described second link with aforementioned exterior edge face tooth engagement fit, it is characterized in that: a Control Shaft is connected with a locking handle in the outside of first link after passing second link and first link successively, described first link can be along the Control Shaft slippage, described locking handle is rotationally connected by bearing pin and Control Shaft, locking handle is provided with an eccentric press part in the joint place with the first link interior edge face, the interior edge face of second link is pressed close in the exterior edge face that the rotation of locking handle can promote first link, so that described exterior edge face tooth and the engagement of interior edge face tooth.
First link can separate automatically with second link under locking handle unlocks state in order to make, be arranged with a spring on the above-mentioned Control Shaft, this spring is supported between first link and second link, makes the exterior edge face of first link and the interior edge face of second link keep separation trend.Like this, after locking handle is removed the locking of first link, under spring action, first link moves along Control Shaft automatically, the exterior edge face of first link and the interior edge face of second link are separated, even exterior edge face tooth and interior edge face tooth are removed engagement, just can lock the adjustment of angle and direction.
For ease of placing mounting spring, be provided with first cavity of putting spring in above-mentioned first link, be provided with second cavity of putting spring in described second link, described spring is positioned at first cavity and second cavity.By spacing to spring of first cavity and second cavity, make spring be difficult for displacement.
The circular insertion part that has evagination on the exterior edge face of above-mentioned first link, described exterior edge face tooth is located on the exterior edge face of this circle insertion part; Have the circular-shaped, concave cavity that indent is inserted for circular insertion part on the interior edge face of described second link, described interior edge face tooth is located on the bottom surface of this circular-shaped, concave cavity.Cooperate by circular insertion part and circular-shaped, concave cavity, can prevent that first link and second link are being offset in the radial direction, guarantee the stability of first link and second link locking.
Compared with prior art, advantage of the present utility model is: during angle adjustment, unclamp locking handle earlier, the interior edge face of first link is left in eccentric press part on the locking handle, first link can move along Control Shaft, under spring action, separate with the interior edge face of second link exterior edge face of first link, make the exterior edge face tooth no longer with the interlock of interior edge face tooth, that is to say that first link can rotate around the axial direction of Control Shaft by relative second link, when deflecting into correct position, oppositely pull locking handle again, the eccentric press part on the locking handle pushes against the interior edge face of first link, promotes first link and moves towards second link along Control Shaft, until exterior edge face tooth and the interlock of interior edge face tooth, locking between first link and second link is finished, and it is few that this locking structure relates to parts, simple in structure, moment of rotation was big when locking handle rotated, rapid operation.
