Description
Technical field
The invention belongs to locking technical field, relate in particular to a kind of throttle operation platform stepless locking mechanism.
Background technology
Traditional power control platform latch mechanism comprises set lever, check lock lever, axle, linkage assembly, friction block, friction disc.In the time promoting set lever from " unclamping " position to " locking " position, set lever is by pulling linkage assembly band moving axis to rotate, axle drives friction block to rotate together, make that friction block and friction disc are because extruding produces friction force in the time that set lever rotates, friction block is fixed on positive push rod as positive push rod provides frictional resistance.Although this structure only needs less space just can realize the locking function of product, but this structure set lever while being positioned at " locking " position in equipment adjustment requires, the central plane of friction block V-type groove must overlap with the central plane of friction disc, guarantee friction block and friction disc reach best friction effect, therefore this structural adjustment difficulty is larger, and there is no stepless locking function, in use there is inconvenience.
Summary of the invention
The one that the object of the invention is to overcome above-mentioned shortcoming and provide is reasonable in design, simple in structure, easy to operate, and has the power control platform latch mechanism of stepless locking function.
Object of the present invention and solve its technical problem underlying and realize by the following technical solutions:
Throttle operation platform stepless locking of the present invention mechanism, comprises set lever, friction disc, axle, check lock lever, and this friction disc is arranged on axle, set lever is arranged on check lock lever upper end, wherein: gear A is installed in described check lock lever lower end, and gear B is arranged on shaft end, and engages with gear A; On axle, be positioned at the screw thread place mounting nuts on gear B right side, on axle, be positioned at nut right side butterfly spring is installed, on axle, be positioned at butterfly spring right side friction disc is installed, on axle, be positioned at friction disc right side gear C is installed; On axle, be positioned at gear C right side friction disc is installed, the end of axle is by bolted; With gear C engagement place, gear D is being installed; Be positioned at check lock lever bottom, steel ball mechanism is installed on gear A top, with steel ball mechanism cooperation place fixed installation chute.
Above-mentioned throttle operation platform stepless locking mechanism, wherein: described nut is designed to double nuts structure.
Above-mentioned throttle operation platform stepless locking mechanism, wherein: the some groups of friction structures that are made up of friction disc, gear C, friction disc are installed on described axle, are respectively organized lining is installed between friction structure.
Above-mentioned throttle operation platform stepless locking mechanism, wherein: described gear A, gear B, gear C, gear D require to be designed to partial gear according to reality locking angle.
The present invention compared with prior art, there is obvious beneficial effect, as can be known from the above technical solutions: gear A is installed in described check lock lever lower end, gear B is arranged on shaft end, and engage with gear A, at the screw thread place on gear B right side mounting nuts, butterfly spring is installed on nut right side, friction disc is installed on butterfly spring right side, gear C is installed on friction disc right side, friction disc is installed on gear C right side, with gear C engagement place, gear D is being installed, nut is designed to double nuts structure, the some groups of friction structures that are made up of friction disc and gear C are installed on axle, between each group friction structure, lining is installed.This structure is at check lock lever during in lock-out state not, push butterfly spring by setting nut, make friction disc extruding gear C, for gear C provides normal pressure, rotation friction between gear C and friction disc increases, thereby gear C engages with gear D while rotation as positive push rod provides damping, make positive push rod reach regulation requirement in lock-out state lower-pilot power not; This structure is in the time that set lever moves to latched position, rotate by the gear A driven gear B on set lever, push butterfly spring thereby drive nut to slide axially, increase the extruding force of butterfly spring, the normal pressure of friction disc is increased, and extruding force is delivered to next friction disc by lining, increases because normal pressure increases the friction force making between gear D and friction disc, in the time that gear C engages with gear D, resistance increases, thereby reaches locking effect.Steel ball mechanism is installed on gear A top, with steel ball mechanism cooperation place fixed installation chute, in the time promoting set lever, steel ball mechanism slides in chute, provide resistance by adjusting steel ball mechanism medi-spring pressure for set lever, make set lever can rest on arbitrarily angled in specialized range, realize the function of stepless speed regulation.Gear A, gear B, gear C, gear D can be locked angle according to reality and be required to be designed to partial gear, can conserve space, save cost.The present invention is reasonable in design, simple in structure, easy to operate, has stepless locking function, has improved reliability and the ease for operation of product.
The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
