Abstract
The utility model discloses an angle locking mechanism which belongs to the furniture field. The angle locking mechanism is composed of a chassis main body, a back bearing plate, a locating piece, a locating shaft bar, an elastic cam, an adjusting shaft, a traction shaft bar and a rotation fulcrum shaft. the chassis main body and the back bearing plate are disposed at the left and right sides of the rotation fulcrum shaft and are connected into together through the rotation fulcrum shaft, the locating shaft bar runs through the locating piece and is fixed on the chassis main body, the other end of the locating piece is connected with the back bearing plate into an integral body through the traction shaft bar, and the elastic cam is placed below the locating piece and is connected with the chassis main body through the adjusting shaft. The angle locking mechanism provided by the utility model can produce locking through simple rotation actions, is simple and convenient to operate, fast and convenient, simple in assembly and easy to assemble.
Description
Technical field
The utility model angle locking mechanism belongs to the chassis structure part using on a tool, and particularly one can secure lock angle, makes the angle of back pad reclining be fixed on multiple locational adjustment structures.
Background technology
The latch-up structure that general traditional seat tool chassis is used, all adopt one can be flexible object, move to another can movable object in screens fix it, to lock angle.But two movable objects, in the dynamic process of working in coordination, because long-term use easily causes the displacement of parts, cause not contraposition of latched position, or locking has some setbacks and maybe cannot lock, and often causes the inconvenience in use.
Utility model content
The purpose of this utility model is with the minimum application of force, the mode of most convenient, and the most stable effect, reaches the object of angle locking, to facilitate all users.
The purpose of this utility model reaches by following measures, and angle locking mechanism comprises: chassis main body, back of the body board, spacer, location mandrel rod, elastic force cam, adjustment axle, traction mandrel rod, rotation fulcrum.Chassis main body and back of the body board connect to one with rotation fulcrum in the left and right sides, and location mandrel rod runs through spacer and is fixed in the main body of chassis, and the other end of spacer links into an integrated entity with traction mandrel rod and back of the body board.Elastic force cam is placed on spacer below, to adjust axle and chassis main body links together.In the time that user rotates adjustment axle, can be with moving cam rotation, and spacer is up pushed up, make to locate mandrel rod to sink in the shrinkage pool on spacer, now spacer is subject to locating blocking of mandrel rod and cannot moves, and produces the effect of locking.Otherwise in the time that elastic force cam rotates towards other direction, elastic force cam can depart from spacer, spacer sinks because of the weight of self, now fixes mandrel rod and can depart from shrinkage pool, and spacer is no longer subject to locating blocking of mandrel rod and can move freely, no longer locking.Spacer has two, has several semicircle shrinkage pools in a row above, and fixing mandrel rod may be stuck in these shrinkage pools, produces locking effect.The determining positions of different shrinkage pools different layback angles.Elastic force cam itself has elastic force, can produce the strength of outer bullet, to withstand spacer, makes fixing mandrel rod may be stuck in locking in shrinkage pool.
The utility model blocks location mandrel rod by the shrinkage pool of spacer, reaches the object of locking.
The utility model, due to the elastic force effect of elastic force cam, reaches and stablizes strong locking effect.
The utility model produces locking by simple spinning movement, easy and simple to handle understandable, and quick and convenient, and assembly is simple, and assembling easily.
Accompanying drawing explanation
Accompanying drawing 1 is example structure schematic diagram of the present utility model: static figure.
Accompanying drawing 2 is example structure schematic diagrams of the present utility model: use case maps.
Accompanying drawing 3 is upward views of the present utility model.
Accompanying drawing 4 is front views of the present utility model.
Accompanying drawing 5 is fractionation schematic diagrams of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: chassis main body 1, adjustment axle 2, elastic force cam 3, location mandrel rod 4, spacer 5, traction mandrel rod 6, back of the body board 7, rotation fulcrum 8.
As shown in accompanying drawing 1-accompanying drawing 5, the quick elastic force adjusting mechanism of the utility model comprises chassis main body 1, adjustment axle 2, elastic force cam 3, location mandrel rod 4, spacer 5, traction mandrel rod 6, back of the body board 7, rotation fulcrum 8.Chassis main body 1 and back of the body board 7 connect to one with rotation fulcrum 8 in the left and right sides, and location mandrel rod 4 runs through spacer 5 and is fixed in chassis main body 1, and the other end of spacer 5 links into an integrated entity with traction mandrel rod 6 and back of the body board 7.Elastic force cam 3 is placed on spacer 5 belows, to adjust axle 2 and chassis main body 1 links together.Chassis main body and back of the body board connect to one with rotation fulcrum in the left and right sides, and location mandrel rod runs through spacer and is fixed in the main body of chassis, and the other end of spacer links into an integrated entity with traction mandrel rod and back of the body board.Elastic force cam is placed on spacer below, to adjust axle and chassis main body links together.In the time that user rotates adjustment axle, can be with moving cam rotation, and spacer is up pushed up, make to locate mandrel rod to sink in the shrinkage pool on spacer, now spacer is subject to locating blocking of mandrel rod and cannot moves, and produces the effect of locking.Otherwise in the time that elastic force cam rotates towards other direction, elastic force cam can depart from spacer, spacer sinks because of the weight of self, now fixes mandrel rod and can depart from shrinkage pool, and spacer is no longer subject to locating blocking of mandrel rod and can move freely, no longer locking.Spacer has two, has several semicircle shrinkage pools in a row above, and fixing mandrel rod may be stuck in these shrinkage pools, produces locking effect.The determining positions of different shrinkage pools different layback angles.Elastic force cam itself has elastic force, can produce the strength of outer bullet, to withstand spacer, makes fixing mandrel rod may be stuck in locking in shrinkage pool.
