Description

A kind of pedal plate resilient mounting of artificial limb foot

[technical field]

The utility model relates to a kind of resilient mounting more particularly to a kind of pedal plate resilient mountings of artificial limb foot.

[background technique]

Artificial limb is suitable for foot amputations patient enough, conventional prosthesis foot in order to restore the ability to act and balanced capacity of patient, Majority realizes the function affect of artificial limb using hydraulic or electronic mode, but this artificial limb cost is high, is unfavorable for pushing away Extensively.The prosthetic structure of hydraulic or electronic mode is complicated, and service life is not grown, and is difficult to once there is component wear situation extensive It is multiple, the use of extreme influence patient.And traditional prosthetic weight weight, the imbalance be easy to causeing between body and artificial limb are long Time using that can allow user's textured bone, influences artificial limb using effect.Also have using spring structure and make artificial limb, still Traditional spring structure artificial limb can not eliminate dynamics when recoil of spring, when leg is by recoil of spring when walking or running Power is pedaled, muscle damage is be easy to cause.Power is pedaled when can reduce recoil of spring it is therefore desirable to provide one kind, and structure is simple, makes With the pedal plate resilient mounting of convenient artificial limb foot.

[summary of the invention]

The utility model aims to solve the problem that the above problem and provides that a kind of structure is simple, light, support degree is big and can reduce Torsional spring pedals the pedal plate resilient mounting of the artificial limb foot of power when springing back.

To achieve the above object, the pedal plate resilient mounting of a kind of artificial limb foot of the utility model, including a support rod 10, set It sets the resilient mounting 20 on support rod 10 and the resistance bullet device 40 of 20 side-lower of resilient mounting is set, the rebound dress Set 20 identical by several shapes, torsional spring 21 not of uniform size is socketed to form, and has gap between adjacent torsional spring 21, on torsional spring 21 It is provided with hole for hoist, torsional spring 21 is lifted on support rod 10 by hole for hoist.

Further, 10 top of support rod is connect with shank attachment device 50, and bottom end is equipped with supporting element 30, supporting element 30 supports the torsional spring 21 of innermost layer.

Further, the resistance bullet device 40 is mounted on pedal plate, and 20 stress of resilient mounting generates deformation and resistance bullet dress 40 contacts are set, resilient mounting 20 is made to generate screen resilience to shank attachment device 50.

Further, 21 surface of torsional spring is provided with unidirectional friction buffer line 22, the resistance bullet device 40 with return The contact surface for playing device 20 is also equipped with unidirectional friction buffer line 22, after unidirectional friction buffer line 22 reduces the generation deformation of torsional spring 21 Screen resilience.

The contribution of the utility model is the provision of a kind of pedal plate resilient mounting of artificial limb foot, the elastic force master of the resilient mounting It to be provided by torsional spring, torsional spring generates the normal condition that deformation provides screen resilience when artificial limb being made to be returned to human body standing enough, is expert at Forward motive force is provided by the screen resilience that torsional spring generates when walking or running, reduces strength consumption when walking.And this is practical The novel socket quantity that torsional spring can be voluntarily adjusted according to human body weight, the people of applicable different weight.In order to avoid torsional spring rebound When dynamics it is excessive and cause the muscle damage to limbs, the utility model is designed there are also unidirectional friction buffer line, is returned in torsional spring When bullet, the power of pedaling of torsional spring is reduced, it is safe and convenient to use.

Fig. 2 is the explosive view of the utility model.

Fig. 3 is the structural schematic diagram that the utility model is mounted on artificial limb foot.

[specific embodiment]

The following example is being explained further and supplementing to the utility model, does not constitute any limit to the utility model System.

Embodiment 1

As shown in Figure 1, 2, 3, the pedal plate resilient mounting of the artificial limb foot of the present embodiment, including a support rod 10, setting are propping up Resilient mounting 20 on strut 10 and the resistance bullet device 40 that 20 side-lower of resilient mounting is set, the resilient mounting 20 by Several shapes are identical, and torsional spring 21 not of uniform size is socketed to form, and have gap between adjacent torsional spring 21, are provided on torsional spring 21 Hole for hoist, torsional spring 21 are lifted on support rod 10 by hole for hoist.10 top of support rod connects with shank attachment device 50 It connects, bottom end is equipped with supporting element 30, and supporting element 30 supports the torsional spring 21 of innermost layer.

Shank attachment device 50 is used to for artificial limb foot connecting with lower leg portion, is provided with support rod in shank attachment device 50 10, support rod 10 is connected to the bottom of shank attachment device 50, and support rod 10 is fixed on resilient mounting 20.When normal stand, Shank attachment device 50 is pushed by the pressure of calf, and 10 load-bearing of support rod is caused to push, and is provided with back below support rod 10 Device 20, deformation retract when resilient mounting 20 is under pressure are played, and provides screen resilience simultaneously to support rod 10, shank is connected and is filled 50 are set to be supported.Resistance plays device 40 and is mounted on pedal plate, and 20 stress of resilient mounting generates deformation and contacts with resistance bullet device 40, makes Resilient mounting 20 generates screen resilience to shank attachment device 50.When walking, due to the angle formed between support rod 10 and pedal plate Smaller, so that the pressure that resilient mounting 20 is subject to is bigger, the screen resilience that at this moment resilient mounting 20 is given is also bigger, can provide walking When forward thrust, labour-saving effect when reaching walking or running.

Embodiment 2

As shown in Fig. 2, 21 surface of torsional spring is provided with unidirectional friction buffer line 22, the resistance bullet device 40 with return The contact surface for playing device 20 is also equipped with unidirectional friction buffer line 22, after unidirectional friction buffer line 22 reduces the generation deformation of torsional spring 21 Screen resilience.

It is excessive in order to avoid returning 20 screen resilience of resilient mounting, cause moment to pedal power macrolesion muscle, the present embodiment is in torsional spring Unidirectional friction buffer line 22 is arranged in 21 the inner surface and the outer surface, and unidirectional friction buffer line 22 can generate deformation in torsional spring 21 and want Friction is generated when returning normal condition, slows down rebound dynamics when torsional spring 21 is sprung back, resistance is played to be also equipped on device 40 and unidirectionally be rubbed Wipe buffering line 22, due to the effect of unidirectional friction buffer line 22, can also slow down rebound velocity, avoid when resilient mounting 20 is sprung back It is excessive and cause muscle damage that moment pedals power.

Although being disclosed by above embodiments to the utility model, the protection scope of the utility model not office It is limited to this, under conditions of conceiving without departing from the utility model, deformation, the replacement etc. done to above each component will fall into this In the scope of the claims of utility model.
