Abstract
The utility model discloses an adjusting device of a head pillow on a backrest, which comprises a stretched shaft and a sleeve tube; a plurality of grooves arranged at the surface of the stretched shaft are locked in the sleeve by a locking mechanism. The utility model is characterized in that the locking mechanism comprises a locking head, a movable component and an elastic component forcing the movable component to move, wherein the locking head is fixedly arranged at one end of the sleeve; a cavity provided with the movable component is arranged in a body of the locking head; the movable component and the locking head are provided with through holes for containing the stretched shaft, and the through holes are communicated with the sleeve; locking bodies which can get into the grooves are arranged at the inner walls of the through holes of the movable component. The utility model has the advantages of convenient adjustment and long service life.
Description
Technical field
The utility model relates to a kind of mechanically-operated controller with Telescopic, particularly a kind of backrest headrest regulator that is used for bed, sofa or seat.
Background technology
Existing backrest headrest regulator is various, and the employing electromagnetic principle that has is realized Telescopic, and what have mechanically stretches by staff.Adopt electromagnetic principle realize Telescopic the backrest headrest regulator since production cost than higher, existing backrest headrest regulator great majority adopt staff mechanically to be adjusted to the master.Mainly be made up of tensile axis and sleeve pipe by the backrest headrest regulator that staff is mechanically regulated, tensile axis is installed in the sleeve pipe by locking mechanism.The employing screw that described locking mechanism has is connected with casing threads tensile axis is locked in the sleeve pipe, when tensile axis is carried out telescopic adjustment, unclamp screw, then tensile axis is stretched to suitable position, tighten screw locking tensile axis at last, its process operation gets up more loaded down with trivial details.The locking mechanism that has is the fixed plastics glue heart in sleeve pipe then, and the plastic cement heart is provided with the through hole that allows tensile axis intert vertically, and the plastic cement heart is connected with the tensile axis interference and locks tensile axis.Because the through hole internal diameter of the plastic cement heart is less than the external diameter of tensile axis, when regulating the stretching distance of tensile axis, nature produces wearing and tearing, heating with the plastic cement heart, and therefore the plastic cement heart is easy to and fatigue damage, shortens the service life of backrest headrest regulator.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of backrest headrest regulator of easy to adjust, long service life.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of backrest headrest regulator, comprise tensile axis and sleeve pipe, the surface of tensile axis is provided with several grooves, and be locked in the sleeve pipe by locking mechanism, it is characterized in that: described locking mechanism comprises tapered end, movable part and the flexible member that forces movable part to move, described tapered end is fixedly mounted on an end of sleeve pipe, be provided with the cavity that movable part is installed in its body, described movable part and tapered end are provided with sleeve pipe and communicate, be used for the through hole of ccontaining tensile axis, the inwall of the through hole of movable part is provided with the lock body that can be absorbed in the groove.
The beneficial effects of the utility model are: because locking mechanism of the present utility model mainly is made of tapered end, movable part and the flexible member that forces movable part to move; As long as press movable part, make the groove of lock body disengaging tensile axis, just can regulate the stretching distance of tensile axis according to actual needs; When desired stretching distance regulated, as long as unclamp hand, movable part outwards moved under the active force of flexible member, locking bar is pressed in the groove of tensile axis again, thereby tensile axis is locked, and therefore the utility model has advantage easy to adjust.In addition, because the utility model is in adjustment process, described lock body does not generally produce with tensile axis and contacts, and they are the phenomenon with regard to not producing wearing and tearing, generating heat naturally between the two, thereby prolongs service life of the present utility model greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the utility model preferred embodiment;
Fig. 2 is the A place enlarged drawing of Fig. 1;
Fig. 3 is the B-B line cutaway view of Fig. 1;
Fig. 4 is the structural representation of another embodiment of the utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2 and Fig. 3, a kind of backrest headrest regulator, comprise tensile axis 1 and sleeve pipe 2, the surface of tensile axis 1 is provided with several grooves 3, and be locked in the sleeve pipe 2 by locking mechanism, described locking mechanism comprises tapered end 4, movable part 5 and the flexible member 6 that forces movable part 5 to move, described tapered end 4 can be by being threaded or mode such as splicing is fixedly mounted on an end of sleeve pipe 2, be provided with the cavity 7 that movable part 5 is installed in its body, described flexible member 6 is installed between the inwall and movable part 5 of cavity 7, described movable part 5 and tapered end 4 are provided with sleeve pipe 2 and communicate, be used for the through hole of ccontaining tensile axis 1, the inwall of the through hole 8 of movable part 5 is provided with the lock body 10 that can be absorbed in the groove 3.As long as press movable part 5, make the groove 3 of lock body 10 disengaging tensile axis 1, just can regulate the stretching distance of tensile axis 1 according to actual needs; When desired stretching distance regulates, as long as unclamp hand, movable part 5 outwards moves under the active force of flexible member 6, again lock body 10 is pressed in the groove 3 of tensile axis 1, thereby tensile axis 1 locking, therefore the utility model has advantage easy to adjust.In addition, because the utility model is in adjustment process, described lock body 10 does not generally produce with tensile axis 1 and contacts, and they are the phenomenon with regard to not producing wearing and tearing, generating heat naturally between the two, thereby prolongs service life of the present utility model greatly.Wherein, described lock body 10 is the higher circular metal bar of strength ratio, and certainly, also the projection 20 that can match at the inwall design and the groove 3 of through hole 8 is as lock body (as shown in Figure 4), and described tapered end 4 can be one-body molded with sleeve pipe 2.
In addition, described flexible member 6 is two compression springs, and described two compression springs are symmetrically distributed, thereby avoids movable part 5 and tapered end 4 to produce excessive friction, guarantees service life of the present utility model.
When preventing that tensile axis 1 from stretching out tapered end 4, described movable part 5 is deviate from from cavity 7, and the inwall of described cavity 7 is provided with groove 11, and movable part 5 is provided with can be in groove 11 movable projection 12.If the space of described groove 11 is enough big, the flexible member 6 that forces movable part to move can be installed in the groove 11, and its two ends contact with the inwall of projection 12 and groove 11 respectively.
Certainly, the utility model is not limited to the foregoing description, and being equal to the utility model or becoming bad technical scheme also should be within the protection domain of the invention.
