Abstract

A seat slewing mechanism of a handicapped mobility scooter comprises a square tube (1), a rotating handle (2), a rotating rod (3), a base board (4), a transmission bar limited block (5), a support (6), a sleeve (7), a circular boss (8), a locking screw(9), a fixture block (10), a torsional spring (11), a pattern card (12), a seat foot tube (13) and a seat rotating shaft (14). The support (6) is welded on the base board (4), the rotating rod (3) is inserted in holes of two lateral plates of the support (6), the sleeve (7) is sleeved on the rotating rod (3) which drives the sleeve (7) to rotate through the locking screw(9), the fixture block (10) and the torsional spring (11) are arranged on the sleeve (7), a plurality of grooves are manufactured on the periphery of the outer edge of the pattern card (12), and the fixture block (10) is clamped in a certain groove of the outer edge of the pattern card (12). The rotating handle (2) is pulled to rotate a seat to enable the fixture block (10) to be clamped in different grooves of the pattern card (12) to enable the seat to stop at different positions, and the fracture surface of the fixture block (10) is a trapezoid with big top and small bottom so that the fixture block (10) can be firmly clamped in the grooves of the pattern card (12). The seat slewing mechanism is simple in structure, flexible in rotation, reliable in location, free of swaying and free of noise.

Description

A kind of instead of walk for invalids vehicle seats rotating mechanism

Technical field

The present invention relates to a kind of seat tumbler, be specifically related to a kind of instead of walk for invalids vehicle seats rotating mechanism.

Background technology

Now general instead of walk for invalids vehicle seats be can not rotate or can rotate arbitrarily, about the inconvenient people with disability.

This utility model is to existing instead of walk for invalids vehicle seats inconvenience people with disability deficiency up and down, design and develop out a kind of simple to operate, rotate flexibly, the reliable instead of walk for invalids vehicle seats rotating mechanism in location.

This utility model is realized through following technical scheme:

A kind of instead of walk for invalids vehicle seats rotating mechanism; Comprise square tube, turning handle, dwang, base plate, drive link limited block, support, sleeve pipe, round boss, lock-screw, fixture block, torsion spring, card, seat foot pipe and seat rotating shaft; It is characterized in that: be processed with some grooves around the card outer rim; A fixture block is arranged on the sleeve pipe, seat fixedly the time fixture block be stuck in a certain groove of card outer rim.

Base plate and square tube weld together and are connected the seat cushion below with bolt, in the middle of floor below, are welded with a seat rotating shaft downwards.

Support is welded on the base plate, on the support biside plate, respectively is processed with a circular hole, and two holes are coaxial, and dwang is inserted in the hole of support biside plate, and the drive link limited block plays position-limiting action.

Casing pipe sleeve is on dwang; Between the support biside plate, in the sleeve pipe middle part one round boss is arranged, screwed hole of processing at the boss center; Position corresponding with screwed hole on dwang processes a plane; A lock-screw is screwed in from screwed hole on the plane that withstands on dwang, during through turning handle rotated bar, drive sleeve pipe through lock-screw and rotate.

Also have a fixture block in the sleeve pipe middle part, the fixture block section is trapezoidal, up big and down small.

Torsion spring set is at telescopic right-hand member, and an end is stuck in the fixture block front end, and the other end is inserted in the aperture of support front end.

Seat foot pipe and card weld together, and are inserted in outside the seat rotating shaft.

Fixture block was not stuck under the effect of torsion spring torsion in the card outer rim a certain groove all around when seat did not rotate.

Want swiveling seat; At first pulling turning handle rotates dwang; The drive sleeve pipe rotates, and overcomes torsion spring torsion fixture block is broken away from the groove of card outer rim, makes seat rotate drive support, sleeve pipe and fixture block when turning to the position of a certain groove of card outer rim together through external force (like buttocks girl power) again; Decontrol turning handle, fixture block is stuck under the effect of torsion spring torsion in a certain groove around the card outer rim.

Because the fixture block section is trapezoidal, up big and down small, so fixture block can tightly be stuck in the card outer rim a certain groove all around, can rock, and not have dry sound.

The beneficial effect of this utility model is:

Simple in structure, rotate flexibly, the location reliably, can not rock no dry.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment a kind of instead of walk for invalids vehicle seats of this utility model rotating mechanism is done further detailed explanation.

Fig. 1 is the front view (look up from under-seat, fixture block is stuck in the groove of card) of this utility model embodiment;

Fig. 2 is the front view (look up from under-seat, fixture block is thrown off in the groove of card) of this utility model embodiment;

Fig. 3 is the A-A cutaway view of this utility model embodiment Fig. 1;

Fig. 4 is the partial enlarged view of this utility model embodiment Fig. 3;

Fig. 5 is the partial enlarged view of this utility model embodiment Fig. 1 core.

Among the figure: 1, square tube; 2, turning handle; 3, dwang; 4, base plate; 5, drive link limited block; 6, support; 7, sleeve pipe; 8, round boss; 9, lock-screw; 10, fixture block; 11, torsion spring; 12, card; 13, seat foot pipe; 14, seat rotating shaft.

The specific embodiment

Be processed with 8 U type grooves around the card 12 from outside to inside, seat fixedly the time fixture block 10 on the sleeve pipe 7 be stuck in the card 12 outer rims a certain groove all around.

Base plate 4 welds together with square tube 1 and is connected under-seat with bolt, and the centre is welded with seat rotating shaft 14 downwards below base plate 4.

Support 6 is welded on the base plate 4, on the biside plate of support 6, respectively is processed with a circular hole, and two holes are coaxial, and dwang 3 is inserted in the hole of support 6 biside plates, and spacing through drive link limited block 5.

Sleeve pipe 7 is enclosed within on the dwang 3; Be positioned in the middle of support 6 biside plates, one round boss 8 arranged, screwed hole of processing at boss 8 centers in sleeve pipe 7 middle parts; Position corresponding with this screwed hole on dwang 3 processes a plane; A lock-screw 9 screwed in from screwed hole withstand on the plane of dwang 3,, drive sleeve pipes 7 through lock-screw 9 and rotate through turning handle 2 rotated bars 3.

Also have a fixture block 10 in the middle part of sleeve pipe 7, fixture block 10 sections are trapezoidal, up big and down small.

Torsion spring 11 is enclosed within the right-hand member of sleeve pipe 7, and an end is stuck in fixture block 10 front ends, and the other end is inserted in the aperture of support 6 front ends.

Seat foot pipe 13 welds together with card 12, is inserted in seat rotating shaft 14 outsides.

Fixture block 10 was not stuck under the effect of torsion spring 11 torsion in the card 12 outer rims groove all around when seat did not rotate.

Want swiveling seat; At first pulling turning handle 2 rotates dwang 3; Through 7 rotations of lock-screw 9 drive sleeve pipes, overcome torsion spring 11 torsion fixture block 10 is broken away from the cards 12 outer rims groove all around, when making seat rotation drive base plate 4, support 6 and fixture block 10 turn to the position of card 12 outer rims a certain groove all around through external force (like buttocks girl power); Decontrol turning handle 2, fixture block 10 is stuck under the effect of torsion spring 11 torsion in the groove around card 12 outer rims.

Because fixture block 10 sections are trapezoidal, up big and down small, so fixture block 10 can tightly be stuck in the card 12 outer rims groove all around, can rock, and not have dry sound.
