The invention relates to a device for adjusting the angle of the back of a foldable product. The device which comprises a knob shaft (1), a spring (3), a fixed pin (5), a wrench (6) and a group of concavo-convex structures (2,4) is characterized in that the spring (3) is arranged between the two concavo-convex structures (2,4); the knob shaft (1) connects the two concavo-convex structures (2,4) in series; the wrench (6) is fixed on the knob shaft (1); and the wrench (6) can adjust the combination and the separation of the two concavo-convex structures (2,4). According to the invention, the knob shaft and the wrench can rotate in a 360DEG mode, the wrench does not randomly drop from the whole adjusting device, and the free rotation of the spring can be maintained during separation of the two concavo-convex structures. The device which is simple and convenient has a very high practical value.
Description
Technical field
The present invention relates to a kind of back angle regulator of collapsible product.
Background technology
We often need it to fold and launch when using the folded products of band back angle regulator, and regulate the angle of back.The adjusting device of product part all adopts concaveconvex structure, adds upper knob in the outside of concaveconvex structure, and the elasticity through adjusting knob realizes concavo-convex combination and separate, reaching locking and to unclamp, thus the effect of regulating backrest angle.This knob structure in the market is a kind of very mature technique.But there are some defectives in this design: when the user is seated or recumbency and when needing to regulate the angle of inclination of backrest, tighten not only time-consuming but also effort after need knob being unclamped again.Secondly, when the user is seated or back-out distance that can't the identification knob during recumbency adjusting knob, so knob often drops easily, and normal use is produced greatly influence.In addition, because device does not exist two concaveconvex structure separated structures, even after knob unclamps, two concaveconvex structures also can be in mutual interlocking pattern, make backrest be difficult to carry out angular adjustment or folding.
Summary of the invention
To above deficiency; The object of the present invention is to provide a kind of back angle regulator of collapsible product; Be to have adopted a kind of spanner in the outside of concaveconvex structure; Control separating and combination of concaveconvex structure through turning on the spanner, thereby realization is locked to the backrest coupling part and is unclamped with pressing down; Through in two concaveconvex structures, adding spring assembly, make two concaveconvex structures after separation, can rotate freely, thus the angle of inclination of free adjustment backrest; Through the integrated design of adjusting spanner, rotation axis, thus the problem of avoiding spanner arbitrarily to drop.
Technical scheme of the present invention realizes in the following manner: the back angle regulator of collapsible product; Comprise rotation axis, spanner, spring and one group of concaveconvex structure; It is characterized in that: at the middle inserting spring device of two concaveconvex structures; Through a rotation axis two concaveconvex structures are connected in series, a spanner is fixed on the rotation axis, the combination of spanner scalable concaveconvex structure with separate.
The spring of described spring assembly is located at the outer rim of rotation axis, spanner upward turn over, two concaveconvex structures keep released state when separating.
Described rotation axis is connected to integral body with spanner, is the center with the rotation axis, can carry out 360 degree rotations around rotation axis.
The dentation sunk part of the dentation projection of described concaveconvex structure (2) in can same concaveconvex structure (4) matches.Opposite, the dentation projection of the dentation sunk part of concaveconvex structure (2) in can same concaveconvex structure (4) matches.
Structure of the present invention, the spring in the knob in the time of can keeping two parts concaveconvex structure to separate be all the time parallel and can the phase mutual interference; Rotation axis connects as a whole with spanner, can carry out 360 degree rotations around rotation axis, and spanner can't drop simultaneously; Whole jockey can press down through spanner in any concaveconvex structure phase interlock place and be fixed, and turns on the spanner its separation.Such structure not only simply but also practical, had very high practical value.

The specific embodiment
Being known by Fig. 1, is the overall diagram of present embodiment.Comprise rotation axis 1, spring 3, steady pin 5, spanner 6 and one group of concaveconvex structure 2,4.The handle of concaveconvex structure 2,4 is connected with the pipe of collapsible product.When pressing down spanner 6, concaveconvex structure 2,4 is realized combining; When on when turning over spanner 6, two concaveconvex structures 2,4 will be realized separating and can realizing rotating freely under the effect of spring 3, thereby realize the adjusting of the folding and backrest inclination angle of collapsible product.
Being known by Fig. 2, is rotation axis of the present invention.In the middle of two concaveconvex structures 2,4, insert a rotation axis 1, spanner 6 is fixed on and revolves on the rotation axis 1.Rotation axis 1 and spanner 6 can be that 360 degree rotations are carried out at the center with the rotation axis.
Being known by Fig. 3, is one side of knob concaveconvex structure of the present invention.Dentalation on the concaveconvex structure is to coincide each other with the another side of concaveconvex structure, and the dentation projection of concaveconvex structure 2 can match with the dentation sunk part in the concaveconvex structure 4.Opposite, the dentation sunk part of concaveconvex structure 2 can match with the dentation projection in the concaveconvex structure 4.Like this, coincideing of continuous dentation jog remains " interlock " state each other after spanner 6 presses down, can not rotate, thus the purpose that reaches folded products or fix its backrest angle.
Being known by Fig. 4, is spring of the present invention.Spring 3 makes it keep the state that separates when on spanner 6, turning over 2,4 separation of two concaveconvex structures, thereby makes two concaveconvex structures 2,4 rotate each other, thereby reaches the purpose that backrest angle is regulated.
Being known by Fig. 5, is the another side of concaveconvex structure of the present invention.Like above-mentioned principle, coincideing of continuous dentation jog remains " interlock " state each other after spanner 6 presses down, can not rotate, thus the purpose that reaches folded products or fix its backrest angle.
Being known by Fig. 6, is steady pin of the present invention.Steady pin 5 is fixed on spanner 6 on the rotation axis 1 firmly, makes spanner 6 can arbitrarily not drop from whole adjusting device.
Being known by Fig. 7, is spanner of the present invention.Spanner 6 is fixed on the button axle 1, and therefore spanner 6 can arbitrarily not drop.Rotation axis 1 and spanner 6 can be that 360 degree rotations are carried out at the center with the rotation axis, and utilize spanner 6 to press down in concaveconvex structure 2,4 phase interlocks place arbitrarily to be fixed.Thereby the purpose that is fixed when reaching folding back or regulating the backrest inclination angle.In like manner,, 2 concaveconvex structures 2,4 are separated, make backrest can arbitrarily rotate, regulate through turning on the spanner 6 in any fixed position.
