Abstract
The utility model discloses a quick elasticity adjusting mechanism, and belongs to the furniture field. The quick elasticity adjusting mechanism comprises a chassis main body, a back bearing plate, a coil spring, a front guiding piece, a front guiding piece, a connecting shaft rod, a movable piece, a positioning block, a fixing shaft rod, a cam, an adjusting shaft, a drawing shaft rod and rotary supporting shafts. According to the utility model, an automatic repairing protective layer can automatically repair scratches on the surface of an optical disk during the use within certain time range, so that the normal reading function of the optical disk can be guaranteed, and the service life of the optical disk can be effectively prolonged; the elasticity can be adjusted through simple rotation, the operation is simple, convenient and easy to understand, quickness and convenience are achieved, the assembly is simple, and the assembling is easy.
Description
Technical field
The quick elastic force guiding mechanism of the utility model belongs to the chassis structure part using on a tool, and particularly relating to one can rapid adjustment spring force, the adjustment structure that the elastic force of back pad reclining is changed.
Background technology
The coil spring that general traditional seat tool chassis is used, all adopts the mode of compression or the spring of loosening, and carrys out the compression elasticity of control spring to change the length of spring.But the control of spring length need to be used the larger application of force, the required adjustment time is also longer, and in the time that spring length diminishes, the screen resilience of generation can become large relatively, causes the difficulty of the application of force in the time adjusting.Very inconvenient compared with little user for dynamics, be even difficult to adjust.
Utility model content
The purpose of this utility model is with the less application of force, in mode fast, reaches the effect that elastic force is adjusted, and increases convenience and practicality, to be suitable for all users.
The purpose of this utility model reaches by following measures, and elastic force guiding mechanism is made up of chassis main body, back of the body board, coil spring, front leader, rear leader, connection mandrel rod, activity template, locating piece, fixing mandrel rod, cam, adjustment axle, traction mandrel rod, rotation fulcrum fast.Chassis main body and back of the body board connect to one with rotation fulcrum in the left and right sides, before coil spring rear and front end is each, leader and rear leader snap together, the rear leader other end is connected with activity template to connect mandrel rod, the other end of activity template is connected in the main body of chassis to fix mandrel rod, locating piece is assembled in the below of activity template, cam is placed on locating piece below, and to adjust axle and chassis main body links together, the other end of front leader links into an integrated entity with traction mandrel rod and back of the body board.
The utility model, by the length of the Angulation changes spring of spring, reaches the object that elastic force is adjusted.
The utility model, by the effect of cam, reaches elastic force output in various degree.
The utility model is adjusted elastic force 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 diagrames of the present utility model: use case maps.
The upward view of accompanying drawing 3 utility models.
Accompanying drawing 4 is front views of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: back of the body board 1, rotation fulcrum 2, traction mandrel rod 3, front leader 4, coil spring 5, adjustment axle 6, connection mandrel rod 7, rear leader 8, cam 9, activity template 10, fixing mandrel rod 11, chassis main body 12, locating piece 13
As shown in accompanying drawing 1-accompanying drawing 4, the quick elastic force guiding mechanism of the utility model comprises back of the body board 1, rotation fulcrum 2, traction mandrel rod 3, front leader 4, coil spring 5, adjusts axle 6, connection mandrel rod 7, rear leader 8, cam 9, activity template 10, fixing mandrel rod 11, chassis main body 12, locating piece 13.Chassis main body 12 and back of the body board 1 connect to one with rotation fulcrum 2 in the left and right sides, before coil spring 5 rear and front ends are each, leader 4 and rear leader 8 snap together, rear leader 8 other ends are connected with activity template 10 to connect mandrel rod 7, and the other end of activity template 10 is connected in chassis main body 12 to fix mandrel rod 11.Locating piece 13 is assembled in the below of activity template 10, and cam 9 is placed on locating piece 13 belows, to adjust axle 6 and chassis main body 12 links together.The other end of front leader 4 links into an integrated entity with traction mandrel rod 3 and back of the body board 1.In the time that rotating adjustment axle, user can be with moving cam rotation, and activity template is up pushed up, cause the Angulation changes of coil spring, coil spring is elongated and elastic force is strengthened, otherwise, in the time that cam rotates towards other direction, spring angle diminishes and elastic force is weakened, and reaches fast the effect that elastic force is adjusted.On cam, there is stepped boss, be used for fixing the anglec of rotation of cam, produce elastic force output in various degree.
