Description

Crutch

Technical field

This utility model relates to a kind of crutch, particularly relates to a kind of crutch of saving material of Improvement type.

Background technology

See also shown in Figure 4, existing crutch includes a main support 50, the sleeve pipe 60 of one hollow and an expansion link 70, main support 50 comprises the two parallel bodies of rod, it is terminal and between the two parallel bodies of rod that the two ends of sleeve pipe 60 are fixed on main support 50, indirectly nearly sleeve pipe 60 places of the two parallel bodies of rod of main support 50 are provided with a handle 51, handle 51 is used for gripping for staff, expansion link 70 1 ends are located in the sleeve pipe 60, be provided with adjusting device between sleeve pipe 60 and the expansion link 70, be used for adjusting expansion link 70 and be located in length in the sleeve pipe 60,, make that the length of main support 50 ends is identical with sleeve pipe 60 because the two ends of sleeve pipe 60 are fixed on the main support 50 with the height of decision crutch integral body.

If user vertically uses crutch, promptly allow crutch perpendicular to ground, this moment, user applied force amount and ground reaction force were mainly born by expansion link 70, the stress intensity that can bear is only relevant with the bar footpath of expansion link 70, if user is because of landform or user mode difference, form an angle less than 45 degree between crutch and ground and make, be fulcrum with expansion link 70 with the joint, ground this moment, the suffered power of crutch can form a moment everywhere to crutch, because of suffered power all identical, so the arm of force far away more is big more apart from ground, then suffered moment is big more, maximal bending moment is at the intermediate point of handgrip 51 with expansion link 70 bottoms, and the chance of the big more feasible fracture of suffered moment is big more.

Therefore the end of main support 50 and sleeve pipe 60 place that interfixes not is the key point place of stress destruction, so the terminal length reality identical with sleeve pipe 60 of main support 50 causes the waste on the material.

This shows that above-mentioned existing crutch obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem that existing crutch exists, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.

Because the defective that above-mentioned existing crutch exists, the design people is based on being engaged in this type of product design manufacturing abundant for many years practical experience and Professional knowledge, and the utilization of cooperation scientific principle, actively studied innovation, crutch in the hope of the minimizing waste of material of founding a kind of new structure, can improve general existing crutch, make it have more practicality.Through constantly research, design, and after studying sample and improvement repeatedly, create this utility model that has practical value finally.

Summary of the invention

The purpose of this utility model is, overcomes inconvenience and defective that above-mentioned existing crutch exists, and a kind of crutch of new structure is provided, and technical problem to be solved is improved crutch, with the waste of minimizing material, thereby is suitable for practicality more.

The purpose of this utility model and to solve its technical problem be to adopt following technical scheme to realize.Crutch according to a kind of new structure that the utility model proposes, it comprises: a main support of being made up of two bodies of rod, two bodies of rod are parallel to each other and have constant spacing, the spacing that two bodies of rod, one end becomes bending inwardly to dwindle two bodies of rod, and the body of rod should form fixed part in the place; Two body of rod other ends are provided with holds up shoulder, and a handle is fixed between two bodies of rod; One sleeve pipe is equiped with expansion link in the one end, is provided with adjusting device in the expansion link, is located in length in the sleeve pipe in order to adjust expansion link; This sleeve pipe in addition end is combined segment, between the formed fixed part of two bodies of rod, on the fixed part of combined segment with 2 two parallel bodies of rod that are fixed on main support.

The purpose of this utility model and solve its technical problem and can also be further achieved by the following technical measures.

The crutch of aforesaid Improvement type, the fixed part of two bodies of rod of wherein said main support is provided with relative two groups fixing hole, and be provided with fixture telescopic combined segment is fixed between two bodies of rod, end at the fixed part of two bodies of rod is provided with a holder, the holder two ends are respectively equipped with a groove with respect to two bodies of rod, and holder central authorities are provided with one with respect to telescopic perforation.

The crutch of aforesaid Improvement type, two body of rod middle sections of wherein said main support are provided with the array hole that is relatively fixed, and handle is fixed on the fixing hole with a fixture.

The crutch of aforesaid Improvement type, wherein said sleeve pipe is provided with the relative through hole of array, expansion link one end is provided with relative through hole, the other end is arranged with a callosity, adjusting device is a U-shaped shell fragment, the shell fragment two ends form a round button that contracts in can pushing respectively, and round button is sticked in the through hole of sleeve pipe and expansion link relatively.

This utility model compared with prior art has tangible advantage and beneficial effect.By above technical scheme as can be known, in order to reach aforementioned goal of the invention, the technological means that this utility model used is to provide a kind of crutch of Improvement type, it comprises a main support, the main support end is to be fixed with a sleeve pipe with fixed part, be equipped with an expansion link in the sleeve pipe, expansion link is to be located in length in the sleeve pipe by an adjusting device adjustment, to change the height of crutch integral body, the length of the fixed part of two bodies of rod of this utility model shortening main support, making sleeve pipe only is the fixed part that is fixed on two bodies of rod by two places on the combined segment, to reduce unnecessary waste of material.

By technique scheme, the crutch of this utility model Improvement type has following advantage at least:

Because user is identical to the application of force size of crutch integral body, when user tilts to use with crutch, promptly allow crutch and ground form one during less than the angle of 45 degree, the arm of force that the point far away more apart from ground produced on the crutch is big more, because stressed size is identical, then moment overhead far away more is big more, then Duan Lie chance is big more, so reduce the length of two parallel body of rod ends, can't influence the stressed of integral body, this utility model is strengthened cleverly and is avoided the maximal bending moment breakdown point, so not only same by this energy fixed sleeving, and can reduce the length of main support, to reach the purpose that reduces waste of material.

In sum, the crutch of this utility model Improvement type, it has above-mentioned many advantages and practical value, and in like product, do not see have similar structural design to publish or use and really genus innovation, no matter it structurally or bigger improvement all arranged on the function, have large improvement technically, and produced handy and practical effect, and more existing crutch has the multinomial effect of enhancement, thereby be suitable for practicality more, and have the extensive value of industry, really be a new and innovative, progressive, practical new design.
