Abstract

The utility model provides an underarm crutch structure. The underarm crutch structure comprises an upper bracket, a lower bracket, a grip and junction components, wherein, a cushion is arranged at the upper part of the upper bracket; two parallel pipe bodies are arranged below the cushion; the lower parts of the two parallel pipe bodies are sleeved on the upper part of the lower bracket; a plurality of penetration holes are formed on the two pipe bodies in corresponding positions from top to bottom; the lower bracket further comprises two parallel pipe bodies; a support leg is arranged at the lower part of the lower bracket; a plurality of penetration holes are formed at the central parts of the two parallel pipe bodies of the lower bracket; the width of the grip is shorter than the distance between the two pipe bodies of the upper bracket as well as the distance between the two pipe bodies of the lower bracket; the junction components are a junction pillar and a nut; the length of the junction pillar is longer than the distance between the two pipe bodies of the upper bracket and the distance between the two pipe bodies of the lower bracket; and the junction pillar is provided with a threaded part, so as to be in threaded connection with the nut. Therefore, the utility model has relatively good applicability and saves materials and manufacture cost.

Description

Structure is turned in the oxter

Technical field

The structurally associated that turn this utility model and a kind of oxter.

Background technology

The oxter is turned and is one of main walk help instrument of behavior inconvenience person, and turn as shown in Figure 6 known oxter, form by body frame 1 ', foot lever 2 ', back cushion 3 ', handle 4 ', Joining device for pipe 5 ', and this body frame 1 ' tool bipole body 11 ', 12 ', and in bipole body 11 ', 12 ' the central correspondence position be provided with the perforation 111 ', 121 "; Foot lever 2 ' is located at body frame 1 ' below again, and can put in order the pattern length of transferring foot lever 2 '; Back cushion 3 ' is fixedly arranged on body frame 1 ' top again, and can be for supporting against the oxter; Handle 4 ' is located between bipole body 11 ', 12 ' again, and the tool open-work, and can by engaging lever 5 ' stretch through perforation 111 ', 121 ' and open-work be mounted on bipole body 11 ', 12 ' suitable height and position, hand can grip handle 4 ' support during use.

Yet the length of aforementioned structure body frame 1 ' is fixed, cause the different users that can not be suitable for as adult, child, and tool large, medium and small three kinds of sizes in commercially available prod are used to cooperate different users's height at present, but so be provided with the increase manufacturing cost and store inconvenient situation, and the oxter of this same pattern is only turned and can be used for the user of corresponding height, causing the oxter to turn can not provide different heights (the height gap is bigger) user to use simultaneously, has the not good disappearance of the suitability.

Moreover aforementioned oxter is turned because of length is fixing and can not be folded, and causes and goes out to put portable inconvenience situation on the car, has the disappearance of portable delivery inconvenience.

The utility model content

The purpose of this utility model is to provide a kind of oxter to turn structure, and its easy disassembling is convenient to portable delivery, the preferable suitability of tool.

For reaching above-mentioned purpose, the technical solution of the utility model is:

Structure is turned in a kind of oxter, and it includes: upper bracket is two bodys, and the top is provided with back cushion, and the number perforation is set on two bodys again; Lower carriage is two bodys, and the below is leg, and this two body can intert combination with aforementioned upper bracket body, and the number perforation is set; Handle is located between two bodys of aforementioned upper and lower support; Conjugative component after upper and lower support adjustment interts pattern length, stretch through upper and lower support the body perforation and make up handle simultaneously.

Described handle is provided with open-work; Conjugative component is Joining device for pipe, nut again, and can the stretch through perforation and the handle open-work of upper and lower support of Joining device for pipe screws togather the nut winding again.

Adopt such scheme, but because two body socket lower carriages, two bodys of this utility model upper bracket, and can adjust pattern length, handle is located at the suitable height punch position of the interspersed junction of upper and lower support again, makes this utility model not only can adjust the pattern length of the upper and lower support in location flexibly, also can adjust the height of handle, the preferable suitability of tool, can reduce manufacturing cost, upper and lower support of the present utility model again is removable to reduce volume, is convenient to portable delivery.

The specific embodiment

See also Fig. 1 to Fig. 3, this utility model includes upper bracket 1, lower carriage 2, handle 3, conjugative component 4, this upper bracket 1 top is provided with back cushion 11, back cushion 11 belows are two parallel tubes 12, the following of this two parallel tubes 12 can socket lower carriage 2 tops, in two bodys, 12 correspondence positions number perforation 13 are set from top to bottom again.

Lower carriage 2 is two parallel tubes 21, and the below is provided with leg 22, in two bodys 21 number perforation 23 is set again.

Handle 3 width are less than two bodys, 12,21 spacings of aforementioned upper and

lower support

1,2, and central authorities establish the open-work 31 that runs through.

Conjugative component 4 can be bond post 41, nut 42, and bond post 41 length are slightly larger than two bodys, 12,21 spacings of aforementioned upper and

lower support

1,2, and the threaded portion is set and is screwed togather by nut 42.

But two bodys, 12 socket lower carriages, 2 two bodys 21 of upper bracket 1 of the present utility model, and can adjust pattern length, make handle 3 be located at

suitable height perforation

13,23 positions of upper and

lower support

1,2 interspersed junctions again, make the

conjugate foramen

13,23 and handle 3 open-works 31 of Joining device for pipe 41 interspersed upper and lower two

bodys

12,21 again, screw togather by nut 42, the feasible pattern length that can locate upper and

lower support

1,2, and as shown in Figure 4, be to adjust pattern length to shorten state.

See also Fig. 5, this utility model is except adjusting the pattern length, also can adjust the group of location handle 3 simultaneously and establish height to make things convenient for the hand gripping, and can reduce the cost of making the different size model, and upper and

lower support

1,2 of the present utility model can be taken apart as shown in Figure 1 to reduce the support volume, be convenient to portable delivery, and this utility model can have aforementioned combination effect concurrently by the minimum cost mode.

In addition, handle of the present utility model can be engaged with upper and lower support by other juncture, thereby previous embodiment is that illustration is set forth this utility model, be not the restriction of this utility model claim, and this utility model can change in this utility model spirit and category or revise.
