Description
The utility model relates to seat, the adjustable cushioning device on particularly a kind of construction machinery and equipment seat.
Existing construction machinery and equipment seat can not be adjusted because of the position, makes the operator can not be in the optimal operations position; Moreover because of seat cushion directly is shelved on the fuselage, no any effect of shaking of keeping away makes the operator be easy to generate fatigue.
The purpose of this utility model provides a kind of construction machinery and equipment seat adjustable cushioning device, and its energy level and lift adjustment seat position has the good function of shaking of keeping away.
A kind of construction machinery and equipment seat adjustable cushioning device described in the utility model comprises the level(l)ing device of parallel motion ground adjusting seat position, it also comprises the elevation and subsidence regulating device of height adjustment seat position, the vibration damping control apparatus of shock preventing device and adjusting vibration damping amplitude; Described level(l)ing device comprises that a suspension holdfast, two upper rails, two lower guideways and handle the bar handle of guide rail; Described elevation and subsidence regulating device comprises two chutes that are positioned at suspension holdfast top, two wherein a pair of goes up that fulcrum can slide, lower fulcrum and intersects strut by the attaching parts bonded assembly in chute, and pass through the attaching parts bonded assembly in the bottom of intersection strut and locate castellated plates, restoring board, limiting stopper, limiting stopper extension spring and promote spring, on the castellated plates of location two above teeth are arranged, when limiting stopper is positioned in the tooth portion under the effect of limiting stopper extension spring, make seat be positioned at different height, restoring board makes limiting stopper break away from the tooth portion of location castellated plates and makes seat return; Described shock preventing device comprises that an adjusting screw(rod) that is provided with is together with regulating handle in the middle of the bottom of intersection strut, one on the other end of adjusting screw(rod) bonded assembly extension spring seat, two at two end places of extension spring seat respectively bonded assembly the damping cylinder of damper spring is housed, one with adjusting screw(rod) bonded assembly dowel bar, one combination bearing that is in transmission connection with dowel bar, and being installed in crescent force transmitting board on the cross-bridging joint element for bar, the crescent force transmitting board is delivered to power on dowel bar, extension spring seat, damping cylinder and the damper spring and realizes keeping away shaking.
Seat position is regulated on parallel motion, lift in height ground before and after the utility model, makes the operator of different heights can both be in the optimum operation position, and the utility model is good keeps away that the function of shaking makes operator's long-time operation and be difficult for producing tired.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a kind of main TV structure scheme drawing of construction machinery and equipment seat adjustable cushioning device.
Fig. 2 is by plan structure scheme drawing shown in Figure 1.
Fig. 3 is by left TV structure scheme drawing shown in Figure 1.
Fig. 4 is the enlarged drawing by part shown in Fig. 1.
Referring to Fig. 1 to Fig. 4, a kind of construction machinery and equipment seat adjustable cushioning device is regulated elevation and subsidence regulating device, the shock preventing device of level(l)ing device, height adjustment seat position of seat position by parallel motion ground and the vibration damping control apparatus of regulating the vibration damping amplitude is formed.
Level(l)ing device is equipped with the bar handle 4 that a suspension holdfast 1, two upper rails 2, two lower guideways 3 and are handled guide rail.Upper rail 2 and lower guideway 3 are installed in the top and the bottom of suspension holdfast 1 respectively.By bar handle 4, unclamp the engaging tooth of guide rail, realize the front and back parallel motion of seat.
Elevation and subsidence regulating device is equipped with two chutes 5 that are positioned at suspension holdfast 1 top, two wherein a pair of goes up that fulcrum can slide, lower fulcrum and intersects strut 6 by the attaching parts bonded assembly chute 5 in, and locatees castellated plates 8, restoring board 9, limiting stopper 10, limiting stopper extension spring 11 and lifting spring 12 by attaching parts 7 bonded assemblys intersecting the bottom of strut 6.On the castellated plates 8 of location three teeth are arranged.During operation, promote the seat on the suspension holdfast 1, intersection strut 6 is risen, the toothed section of at this moment locating castellated plates 8 is also along with rising, when limiting stopper 10 is positioned in the tooth portion under the effect of limiting stopper extension spring 11, just can make seat be positioned at different height, continue to promote seat, restoring board 9 makes limiting stopper 10 break away from the tooth portion of location castellated plates 8, and put down seat this moment makes seat return.
Shock preventing device is equipped with an adjusting screw(rod) 13 that is provided with together with regulating handle 14 in the middle of the bottom of intersection strut 6, one on the other end of adjusting screw(rod) 13 bonded assembly extension spring seat 15, two at two end places of extension spring seat 15 respectively bonded assembly the damping cylinder 17 of damper spring 16 is housed, one with adjusting screw(rod) 13 bonded assembly dowel bars 18, one combination bearing 19 that is in transmission connection with dowel bar 18, and be installed in crescent force transmitting board 20 on the cross-bridging joint element for bar 7.When seat is subjected to impact load, by the crescent force transmitting board 20 on the intersection strut 6 power is delivered on dowel bar 18, extension spring seat 15, damping cylinder 17 and the damper spring 16, and is absorbed, thereby realizing keeping away shakes.
The vibration damping control apparatus comprises adjusting screw(rod) 13, regulating handle 14, extension spring seat 15 and can show the telltale 21 of human body weight scale.Rotation adjusting screw(rod) 13 during use, front and back parallel motion extension spring seat 15 elongates or shortens damper spring 16, regulates the vibration damping amplitude by the starting force that changes damper spring 16.The adjusting of vibration damping amplitude can show that the people of different weight can both be in the best state of shaking of keeping away thus by telltale 21.
