Description
Technical field:
This utility model relates to a kind of medical treatment and nursing wheelchair.
Background technology:
The wheelchair that medical treatment and nursing is used patient is for convenience stood and is sat down, and convenient collection, the capital is made pedal frame rotating, retaining mechanism is set between chair frame and pedal frame again, existing retaining mechanism is to be fixed together and to realize being separately positioned on stator on the chair frame and the stator on the pedal frame by interference fit, but this retaining mechanism wearing and tearing will occur along with often reusable, pedal frame is loosening easily in causing using backward, influence the service life of pedal frame, when in addition pedal frame being carried out lock and unlock, require operator to grant bigger power, could realize the lock and unlock action, the application of force is not enough during if lock, and is just unreliable to the locking of pedal frame.
Summary of the invention:
The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, and a kind of pedal frame reliable lock, durable wheelchair retaining mechanism of making is provided.
For achieving the above object, the technical scheme that this utility model provides is: a kind of medical treatment and nursing retaining mechanism of wheelchair, include axle center tube and the pedal frame of being located at chair frame front end, the axle center tube is rotatably assorted with foot-operated putting up, correspondence has hole clipping and pilot hole respectively on axle center tube and the same relative position of pedal frame, an interspersed lock pin in two holes.
In the pilot hole of pedal frame, be provided with the back-moving spring that is connected on the lock pin, handgrip be installed in the outer end of described lock pin.
The surface configuration of the surface configuration of described handgrip and pedal frame and this handgrip joint is complementary.
Form boss on the wall body of axle center tube, be provided with gathering sill on boss, the top of this gathering sill is provided with locating part, and corresponding position is provided with the turntable that cooperates with gathering sill on the pedal frame.
After adopting technique scheme, utilize lock pin that pedal frame and axle center tube are locked, this locking mode is very reliability and durability, at the lock pin end handgrip that the surface configuration of surface configuration and pedal frame joint is complementary is set in addition, while cross-under back-moving spring on lock pin, make operator as long as rotate handgrip a little, the head of lock pin will be pulled away from the hole clipping of axle center tube, pedal frame is unlocked, rotate handgrip again, lock pin its head under the effect of back-moving spring is pushed in the hole clipping of axle center tube, and pedal frame is locked, and operates quite light.
Description of drawings:
Fig. 1 is that this utility model wheelchair pedal frame produces the three-dimensional structure diagram when using;
Fig. 2 is the three-dimensional structure diagram after the pedal frame of this utility model wheelchair goes back to;
Fig. 3 is the axle center tube of this utility model wheelchair and the three-dimensional exploded view of pedal frame swivel;
Fig. 4 is the structure chart of swivel portion after the release of this utility model wheelchair pedal frame;

The specific embodiment:
Now elaborate this utility model in conjunction with the accompanying drawings:
This wheelchair includes seat support 1, chair frame 16, two side wheels 2, is located at the cylinder axle center tube 3 and the pedal frame 4 of chair frame 16 front ends, pedal frame 4 inserts in the top of axle center tube 3, and can rotate around axle center tube 3, stretching out at the middle part of axle center tube 3 barrels, to form the wall body surface configuration be arcual boss 5, upper surface at arc boss 5 forms gathering sill 6, be provided with locating part 7 above gathering sill 6, the front end face of arc boss 5 forms hole clipping 8; Extending internally and be provided with swivel 9 on the pedal frame 4 with on the position of axle center tube 3 sustained heights, the downward elongation moulding in the rear portion of this swivel 9 has sliding stand 10, sliding stand 10 cooperates with the gathering sill 6 and the locating part 7 of arc boss 5, when pedal frame 4 rotates, sliding stand 10 slides between the gathering sill 6 and locating part 7 of arc boss 5, the action of producing that guarantees pedal frame 4 is stablized, the anterior elongation moulding downwards of swivel 9 has the lock pin mounting blocks 11 that cooperates with arc boss 5, the front/rear end of this lock pin mounting blocks 11 all is an arcuate shape, the rear end face of swivel 9 is designed to the circular end surface that is complementary with axle center tube 3 barrel shapes, the position of corresponding hole clipping 8 is provided with pilot hole 12 on lock pin mounting blocks 11, lock pin 13 passes pilot hole 12 and is inserted in the hole clipping 8, leave the back-moving spring 14 that is through on the lock pin 13 in the pilot hole 12, the outer end of lock pin 13 is equipped with handgrip 15, and the surface configuration of the surface configuration of this handgrip 15 and swivel 9 and these handgrip 15 joints is complementary.
When producing pedal frame 4, after pedal frame 4 forwards the position to, rotate handgrip 15, back-moving spring 14 advances lock pin 13 in the hole clipping 8, pin pedal frame 4, during release, rotate handgrip 15, under the cooperation of the front end face of handgrip 15 and lock pin mounting blocks 11, lock pin 13 rear ends are pulled away from hole clipping 8, and pedal frame 4 just can rotate, this structure reliable lock, durable, and operation is quite easy to be laborsaving.
The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to this utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
