A kind of quick lock mechanismTechnical field
The present invention relates to quick lock mechanism technical field, be specifically related to a kind of quick lock mechanism.
Background technique
Quick lock mechanism is the mechanism for fixing article fast, and the kind of quick locking structure is varied, and its complex structure of general quick locking structure, cost is high.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned defect, provides a kind of quick lock mechanism, and structure is simple, and cost is low, fixing reliable.
The technological scheme that the present invention solves the employing of its technical problem is as follows:
A kind of quick lock mechanism, comprise clamp, torsion spring, push rod, pedestal, it is characterized in that: described clamp is fan-shaped clamp, what fan-shaped clamp tilted is arranged in pedestal, clamp rear end is flexibly connected with pedestal with bearing pin, the scalloped end part of fan-shaped clamp leans out pedestal top, corresponding part, pedestal top is provided with breach, scalloped end is dentation structure, clamp plate is provided with groove with it, described torsion spring is flexibly connected with bearing pin, one end is embedded in groove, the other end is resisted against pedestal bottom surface, clamp rear end is provided with downward-sloping driving lever, described push rod is horizontally set in pedestal, push rod front end and driving lever hinged, push rod rear end leans out and is slidably matched with pedestal to pedestal is outside, driven forward push rod, push rod pushes driving lever and moves forward, driving lever drive clamp with bearing pin place for axial pedestal inward turning turns, make clamp scalloped end lean out pedestal outside and rotate into pedestal inside, pedestal is snapped in mounting hole, unclamp push rod, clamp scalloped end resets, the teeth of the dentation structure of clamp scalloped end clamp with installation hole wall, the elastic force of torsion spring is applied directly on clamp, the teeth of the dentation structure of clamp are tightly stuck in mounting hole inwall, fixing is firm, structure is simple, cost is low.
Further, the tendency direction that described driving lever true dip direction and torsion spring are resisted against one end, pedestal bottom surface is consistent, push rod is pushed clamp is rotated.
Further, the fan-shaped of described clamp scalloped end is that gradual change is fan-shaped, and clamp scalloped end leans out and becomes large gradually to the outside radius being in part in pedestal of assigning to of pedestal, is convenient to clamp scalloped end and rotates back to pedestal inside smoothly.
The invention has the beneficial effects as follows: adopt such scheme, directly act on fan-shaped clamp with the elastic force of torsion spring, the teeth of clamp scalloped end and mounting hole inwall are tightly fitted refined clamping, what make to fix is more firm, and simply, cost is low for structure.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Fig. 1 is schematic cross-section of the present invention.
Wherein: 1 is pedestal, 2 is clamp, and 3 is torsion spring, and 4 is bearing pin, and 5 is push rod, and 6 is driving lever.
Embodiment
A kind of quick lock mechanism as shown in Figure 1, comprise fan-shaped clamp 2, torsion spring 3, push rod 5, pedestal 1, what fan-shaped clamp 2 tilted is arranged in pedestal 1, its rear end is fixed on the inside of pedestal 1 with bearing pin 4, clamp 2 can rotate around bearing pin 5, the scalloped end part of clamp 2 leans out pedestal 1 top, the top of corresponding pedestal 1 is provided with breach, and scalloped end is that gradation type is fan-shaped, from leaning out, part is gradually large to its diameter of part being in pedestal 1, scalloped end is dentation structure, the plate of clamp 2 is provided with groove with it, torsion spring 3 is flexibly connected with bearing pin 4, its one end is embedded in groove, the other end is resisted against the bottom surface of pedestal 1, the rear end of clamp 1 is provided with downward-sloping driving lever 6, the tendency direction of one end that driving lever 6 is corresponding with pedestal 1 bottom with torsion spring 3 is consistent, push rod 5 is horizontally set in pedestal 1, front end and the driving lever 6 of push rod 5 are hinged, the rear end of push rod 5 leans out and is slidably matched to the outside of pedestal 1 and pedestal 1.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
