The utility model content:
The purpose of this utility model is to provide a kind of office chair rotation durability test machine at the deficiencies in the prior art, and not only vibration equipment is little, and noise is little, and equipment is small, convenient mounting and clamping.
For achieving the above object, the utility model adopts following technical scheme:
Office chair rotation durability test machine, it comprises support and is used to place the rotating disk of office chair that it also comprises motor, reductor, driving gear, driven gear, seat fixed mechanism and chair pawl fixed mechanism; Described motor is fixed in support, and motor-driven connects reductor, and reductor drives and connects driving gear, driving gear and driven gear engagement, and driven gear connects described rotating disk, and described seat fixed mechanism and chair pawl fixed mechanism all are installed in described support.
It also comprises main shaft, and described driven gear connects described rotating disk by main shaft.
Described seat fixed mechanism comprises the platen that is arranged at the office chair two sides and compresses the office chair two sides.
Described seat fixed mechanism also comprises the pillar that is arranged at support, and described pillar is connected with handle, and handle connects described platen.
But described chair pawl fixed mechanism comprises up-down adjustment and compresses the press strip of chair pawl.
Described chair pawl fixed mechanism also comprises screw mandrel, and the screw mandrel bottom is threaded with support, and the screw mandrel top is threaded with press strip.
The utility model beneficial effect is:
Office chair rotation durability test machine described in the utility model, it comprises support and is used to place the rotating disk of office chair that it also comprises motor, reductor, driving gear, driven gear, seat fixed mechanism and chair pawl fixed mechanism; Described motor is fixed in support, and motor-driven connects reductor, and reductor drives and connects driving gear, driving gear and driven gear engagement, and driven gear connects described rotating disk, and described seat fixed mechanism and chair pawl fixed mechanism all are installed in described support.Adopt the office chair rotation durability test machine of said structure, owing to adopt two gear reductions, the equipment center of gravity is descended, reduced the height of support, thereby reduced the vibration and the noise of equipment, make equipment small, clamping is more convenient.
Description of drawings:
Accompanying drawing 1 is an external structure synoptic diagram of the present utility model;
Accompanying drawing 2 is inner structure synoptic diagram of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As depicted in figs. 1 and 2, office chair described in the utility model rotation durability test machine, it comprises support 13, is used to place the rotating disk 8 of office chair 5, motor 11, reductor 2, driving gear 1, driven gear 9, seat fixed mechanism and chair pawl fixed mechanism; Described motor 11 is fixed in support 13, motor 11 drives and connects reductor 2, reductor 2 drives and connects driving gear 1, driving gear 1 and driven gear 9 engagements, described driven gear 9 connects described rotating disk 8 by main shaft 10, and described seat fixed mechanism and chair pawl fixed mechanism all are installed in described support 13.
As preferred embodiment, described seat fixed mechanism comprises the platen 3 that is arranged at office chair 5 two sides and compresses office chair 5 two sides, and the pillar 12 that is arranged at support 13, and described pillar 12 is connected with handle 4, and handle 4 connects described platen 3.Before the test, by turning handle 4, promptly the position of scalable platen 3 makes the platen 3 of office chair 5 two sides can compress office chair 5 two sides tightly, prevent office chair 5 displacements in the test process and influence test structure, have advantage simple in structure, easy to adjust.
As preferred embodiment, but described chair pawl fixed mechanism comprise up-down adjustment and compress the press strip 6 and the screw mandrel 7 of chair pawl, screw mandrel 7 bottoms are threaded with support 13, screw mandrel 7 tops are threaded with press strip 6.Before the test, regulate the upper and lower displacement of press strip 6, make press strip 6 can compress five pawls of chair bottom tightly, prevent that five pawls produce displacement and influence test structure in the test process, have advantage simple in structure, easy to adjust by rotary screw rod 7.
Office chair rotation durability test machine described in the utility model, its principle of work is: motor 11 is fixed on the bottom of support 13, by giving top rotating disk 8 transmission of power by main shaft 10 after the deceleration of reductor 2, driving gear 1, driven gear 9, make the speed rotation of rotating disk 8 with 6r/min.Office chair 5 is placed on the rotating disk 8, is added with the sandbag load of regulation on the seat, and office chair 5 both sides are fixed with pillar 12, two platens 3 are installed on the pillar 12, platen 3 can carry out front and back by the rotation of handle 4 to be regulated, and the both sides of office chair 5 are withstood, and its seat can not rotated.Five pawls below the office chair 5 are fixing by press strip 6, are locked on the support 13 with screw mandrel 7, make castor follow following rotating disk 8 and rotate in opposite directions; Rotating disk 8 rotations of energising back so just can be tested office chair 5 life-span in this state, learn the rotation endurance quality of pulley.Owing to adopt two gear reductions, the equipment center of gravity is descended, reduce the height of support 13, thereby reduced the vibration and the noise of equipment, make equipment small, clamping is more convenient.
