Abstract
The utility model provides a mechanical seat adjusting rod, comprising a front mounting card and a rear mounting card. The rear mounting card is fixedly connected with an inner threaded pipe. A three-jaw threaded rod which can engage with and disengage from the inner threaded pipe is arranged in the inner threaded pipe. The three-jaw threaded rod is sheathed with an outer spring which can limit the axial position of the inner threaded pipe. The three-jaw threaded rod is sheathed on a control lever which can make the threaded rod tighten and relax. The control lever is supported in the front mounting card. The motion of the control lever is controlled by the control lever hinged on the front mounting card and a return spring mounted on the control lever. The utility model is suitable for various types seats on vehicles and similar devices for the use of regulating the angle.
Description
The utility model relates to a kind of seat mechanical type adjust bar that can adjustment seat chair back angle, is applicable to that all kinds seat and allied equipment are adjusted angle on the vehicle to use.
Known seat adjustment bar has air pressure piston type adjust bar and mechanical type adjust bar.In the air pressure piston type adjust bar control cock is housed, and the requirement on machining accuracy height of piston and cylinder, this adjust bar cost is very high, its adjustment pressure and design theory pressure greatly differ from each other, and pressure is too big, regulate very inconvenient, the leakage of oil in addition, the gas leak phenomenon that have, influence self-locking performance, and bad maintenance, often cause adjust bar to scrap easily.The mechanical type adjust bar is made up of a sleeve and axle with matching, on axle, be milled with an elongated slot, sleeve radially is equipped with certain position pin, and locating dowel pin is inserted in the elongated slot just can control pinion and the relatively rotating of axle, and the another side of axle is drilled with three holes vertically, sleeve radially is equipped with the locating dowel pin of a telescopic band handle, this locating dowel pin is inserted in wherein the hole, has just determined the extension position of phase place, and it is inferior therefore just can only to regulate several retainings, can not realize step-less adjustment, volume is attractive in appearance greatly and not.
The purpose of this utility model is to overcome above-mentioned deficiency and a kind of light seat mechanical type adjust bar of regulating is provided.
The utility model provides a kind of seat mechanical type adjust bar, card is installed before comprising card is installed with the back, the back is installed on the card and is fixedly connected with rifled pipe, have in the rifled pipe and can be engaged with and out-of-gear three-jaw thread rod, be set with the outer spring that limits the rifled pipe axial location on the three-jaw thread rod, the three-jaw thread rod is sleeved on the control stalk that enables tensioner and loosen, in the installation card, the motion of control stalk was by the joystick and the pull back spring control that is contained on the control stalk installed before being hinged on the card before control stalk was bearing in.Stir joystick, control stalk is moved right, thereby make three-jaw thread rod and rifled pipe jump out of mesh, this moment, the three-jaw thread rod can move with respect to rifled pipe, after meeting the requirements of the position, loosen joystick, control stalk is return tensioner three-jaw thread rod under the effect of pull back spring, three-jaw thread rod and rifled pipe mesh again, and outer spring holds out against rifled pipe.
The right-hand member of above-mentioned rifled pipe is captiveed joint with the rear head on being connected in back installation card, can be threaded or adopt alternate manner to connect, have in the rifled pipe with the three-jaw thread rod on the negative thread of threaded engagement, outer spring is installed the step location on the front head on the card by the left side of rifled pipe with before being connected in.
Have the inner via hole that diameter does not wait in the above-mentioned three-jaw thread rod, with dress control stalk and pull back spring, the left end of three-jaw thread rod is sleeved on the front head, and right-hand member is meshed with rifled pipe, the right-hand member of three-jaw thread rod has outside thread, and threaded shaft respectively has three grooves to equidistantly outside.
The left part of above-mentioned control stalk is bearing in preceding installation and fastens in the bonded assembly front head, its left part contacts with joystick, match with the endoporus of three-jaw thread rod in the middle part, pull back spring is by the inner hole wall location that is connected in stop collar on the control stalk and three-jaw thread rod, the right-hand member of control stalk is fixed with the tensioner pin of tensioner three-jaw thread rod, axially being located by nut of tensioner pin.
Install before during use and fasten on cushion, the back is installed and is fastened on seat, stirring the joystick push lever moves right, the tensioner pin skids off from the inner via hole of three-jaw thread rod gradually, three-jaw thread rod radial shrinkage and break away from screw-threaded engagement with rifled pipe, the three-jaw thread rod can move arbitrarily in rifled pipe, when moving on to desired location, loosen joystick, under the effect of pull back spring, the tensioner pin puts in the inner via hole of three-jaw thread rod gradually, and the outside thread of three-jaw thread rod and rifled pipe are meshed again, and reaches the purpose of length adjustment.When the three-jaw thread rod was transferred to Len req, outer spring stretching rifled pipe reached the purpose of locking.Change the length of three-jaw thread rod, make the backrest of automotive seat obtain required angle.
Therefore the utility model has overcome the shortcoming of existing adjust bar, and requirement on machining accuracy is not too high, and actuating force can reach designing requirement according to the size of spring force, has cost low, regulate light, step-less adjustment, self-locking performance is good, the advantage that volume is little.
