Abstract

The invention relates to a medical walking stick. A straight rod penetrates through an elastic ring stop block, an elastic ring, an auxiliary foot frame and an auxiliary foot stop block in sequence. The elastic ring stop block and the auxiliary foot stop block are fixed to the straight rod through bolts. The tail end of the straight rod is a main supporting point. The upper end face and the lower end face of the elastic ring make contact with the elastic ring stop block and the auxiliary foot frame respectively to provide buffer for the auxiliary foot frame when the auxiliary foot frame is stressed. The periphery, where the auxiliary foot frame is located, of the straight rod is provided with a guide groove. The position, corresponding to the auxiliary foot frame, of the guide groove is provided with a pin hole. The auxiliary foot support is arranged between the guide groove and the pin hole through a pin. The medical walking stick is small in mass and compact in structure and provides a more stable and labor-saving support for users, parts are easy to manufacture, and the scheme is easy to implement.

Description

A kind of medical crutch

Technical field

the present invention relates to a kind of medical crutch, belong to medical instruments field.

Background technology

Current, the medical crutch that user uses mostly is any and contacts to earth, and this brings many hidden danger: one, and when ground smoother, user very easily slides in moving process; Its two, user often uses crutches, occurs that only crutches contact to earth in moving process, be now 2 stressed, and unstable; Its three, in order to maintain 2 stressed stability, user can only be exerted oneself comparatively large, mobile slower; Its four, user at some in particular cases, uses when singly turning, i.e. user list lower limb and singly turn and can only provide two strong points, poor stability.

Summary of the invention

The object of this invention is to provide a kind of crutch that can improve the stability under loading of existing medical crutch.

The axil bar of medical crutch of the present invention and hand lever, identical with general crutch, the two all with turn frame and be connected, and in a plane; The main support point that main foot rest provides for crutch, the invention is characterized in:

Straight-bar is successively through playing ring stops, playing ring, auxiliary foot rest and auxiliary foot stops, bullet ring stops and auxiliary foot stops are bolted on straight-bar, the end of straight-bar is main fulcrum, and two end faces up and down playing ring contact with bullet ring stops and auxiliary foot rest respectively, for auxiliary foot rest stressed time buffering is provided; The straight-bar of auxiliary foot rest position has a gathering sill, and the correspondence position of gathering sill and auxiliary foot rest has pin-and-hole, installs auxiliary foot rest by pin between gathering sill and pin-and-hole, auxiliary foot rest is provided with auxiliary foot support.

The auxiliary foot support number of described auxiliary foot rest is 4-8, and length and the mutual angle thereof of auxiliary foot support can freely design within the specific limits.

Preferably, play ring and select elastomeric material, should rubber be used.

Preferably, the end of straight-bar is that main fulcrum and auxiliary foot support end adopt the coefficient of friction materials that are large, wear-resisting, somewhat resilient such as hard rubber to wrap its end as auxiliary callosity and main callosity.

The present invention can be the more stable support that user band derives from crutch, and with certain stressed dull and bored sensation overcoming single supporting point walking stick, has the effect that certain psychology is auxiliary.User is when using crutch walking, and contain regularly in continuous change by turning the power transmitting, the pain that user axillary fossa receives pressure and brings can be eased; Quality is little, compact conformation, and part makes simple, easily realizes.

Accompanying drawing explanation

the structural representation of the crutch that Fig. 1 provides for the embodiment of the present invention;

Fig. 2 is five auxiliary fulcrum schematic diagrams of the auxiliary foot rest of part.

Detailed description of the invention

For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.

As shown in Figure 1, a kind of medical crutch provided by the invention, is comprised two and turns frame 1, be connected by screw with hand lever 2, axil bar 3, and two are turned frame 1 and are connected by bolt with straight-bar 4.The main fulcrum 11 of straight-bar 4 end is equipped with main callosity 10.Straight-bar 4 is from top to bottom successively through fixing spring stops 5, bullet ring 6, auxiliary foot rest 7 and auxiliary foot rest stops 8.Straight-bar 4 has two through holes, play ring stops 5, auxiliary foot rest stops 8 by bolt is fixing respectively.Playing ring stops 5 to be connected with bullet ring 6, providing stop surface for playing ring 6.Straight-bar 4, through the centre bore of auxiliary foot rest 7, makes auxiliary foot rest 7 and plays ring 6 and contact, and fixes the degree of freedom that rotates in a circumferential direction of auxiliary foot rest 7 by the pin-and-hole 13 on the gathering sill of straight-bar 4 and auxiliary foot rest 7, makes auxiliary foot support 14 near outside of foot.

As shown in Figure 1, in the present embodiment, auxiliary foot rest stops 8 contacts with auxiliary foot rest 7, realizes the restriction of auxiliary foot rest 7 to straight-bar end movement.

As shown in Figure 2, in the present embodiment, auxiliary foot rest 7 is welded with 14 to No. 18 auxiliary foot supports, the end of 5 auxiliary foot supports is all equipped with auxiliary callosity 9.

Use procedure of the present invention is described below: user both hands respectively hold a crutch, the auxiliary fulcrum place plane of auxiliary foot support 14 is parallel with body abdominal part place plane, and in the one end near health, during walking, the auxiliary fulcrum of auxiliary foot support 15 and 17, the auxiliary fulcrum of auxiliary foot support 16 and 18 in succession with main fulcrum 11 kiss the earth, replace auxiliary fulcrum and main fulcrum 11 kiss the earth of auxiliary foot support 14, form two stable face contacts.Wherein only the auxiliary fulcrum of auxiliary foot support 14 and main fulcrum 11 kiss the earth time, auxiliary fulcrum and the main fulcrum 11 of two crutch auxiliary foot support 14 separately form a plane, provide stable support.

User is when using crutch walking, and the power of being come up by crutch transmission contains regularly in continuous change, and the pain that user axillary fossa receives pressure and brings can be eased.

User is static, during alone crutch, by the auxiliary fulcrum of the auxiliary fulcrum of auxiliary foot support 15 and 17 or auxiliary foot support 16 and 18 near body side, can form plane and contact to earth simultaneously, to obtain more stable support with main fulcrum 11.

Preferably, to have a certain degree relation at five auxiliary stands of described auxiliary foot rest, wherein the auxiliary fulcrum place plane of auxiliary foot support 14 and axil bar and plane being perpendicular that hand lever is formed; The auxiliary fulcrum place plane of the auxiliary fulcrum of auxiliary foot support 15 and the auxiliary fulcrum of auxiliary foot support 16 place plane and auxiliary foot support 14 separately all coordinates 70 °, is distributed in the both sides of the auxiliary fulcrum of auxiliary foot support 14; The auxiliary fulcrum place plane of the auxiliary fulcrum of auxiliary foot support 17 and the auxiliary fulcrum of auxiliary foot support 18 place plane and auxiliary foot support 14 separately all coordinates 110 °, is distributed in the both sides of the auxiliary fulcrum of auxiliary foot support 14.
