Specific embodiment

In order to illustrate more clearly of the utility model embodiment and technical solution in the prior art, attached drawing will be compareed below Illustrate specific embodiment of the present utility model.It should be evident that the accompanying drawings in the following description is only the one of the utility model A little embodiments for those of ordinary skill in the art without creative efforts, can also be according to these Attached drawing obtains other attached drawings, and obtains other embodiments, and the utility model is not restricted to the embodiment.

Please refer to Fig. 1 to Fig. 5, a kind of Multifunctional liftable handrail of the utility model embodiment, including, handrail lid 1, support Frame 2, support leg 3, the handrail lid 1 include being used to support the balustrade panel 11 of user's arm, for connecting handrail lid 1 and support frame 2 connecting component, support frame as described above 2 include for going up and down the elevating lever 4 of handrail, the locating part 6 for limiting elevating lever 4, use Fixing piece 5, the first sleeve 21 for accommodating elevating lever 4, second set for accommodating first sleeve 21 in fixed elevating lever 4 Cylinder 22 goes up and down the lifting for realizing handrail entirety by first sleeve 21 in second sleeve 22.

In above structure, the connecting component is set in handrail lid 1, and is connected with locating part 6, and the locating part 6 is solid It connects in first sleeve 21, is partially limited in locating part 6 on elevating lever 4, therefore, elevating lever 4 goes up and down to realize, it is necessary to So that locating part 6 moves therewith, and locating part 6 is fixed in first sleeve 21, and is connected with connecting component, so limit The movement of position part 6 also will drive the movement of first sleeve 21 and handrail lid 1, realize the lifting of handrail.Conversely, passing through handrail or the One sleeve 21 also will drive locating part 6 or even elevating lever 4 moves, so that being able to achieve external action adjusts elevating lever 4, to adjust The height of support frame 2.

According to described above, if above structure does not increase some lifting supplementary structures, this utility model one kind is multi-functional Liftable armrest may be designed as a kind of purely manual lifting handrail, and user is by applying one to handrail lid 1 or first sleeve 21 Active force upward or downward changes the height of handrail.

In this example, 4 both ends of elevating lever all have bending and contrary protrusion 42.

Wherein, two 42 functions of protrusion are different, limit on locating part 6 elevating lever 4 of part it is convex Switching function is played in portion 42 out, which is inserted into the emptying aperture of first sleeve, and the protrusion 42 and fixing piece 5 of the other end match Close the fixed function to elevating lever 4.

In this example, 4 two sides of elevating lever are equipped with limited post 41, limit to match with locating part 6 elevating lever 4 Position.

In this example, the locating part 6, which is equipped with the limiting groove 62 of accommodating limited post 41 and accommodates elevating lever 4, is equipped with limited post The elevating lever groove 61 of 41 parts.

Among the above, the limiting groove 62 accommodates limited post 41, and the elevating lever 4 accommodates the upper part of elevating lever 4, described The cooperation of limited post 41 and limiting groove 62 can make locating part 6 have better limit effect to elevating lever 4, to reduce liter The probability that drop bar 4 shakes in locating part 6.

In this example, the locating part 6 is set in first sleeve 21.

Above-mentioned by the agency of mistake, locating part 6 are fixed in first sleeve 21, enable locating part 6 and first sleeve 21 It moves together.

In this example, the first sleeve 21 is equipped with through-hole 211 corresponding with the protrusion 42 that 4 one end of elevating lever is bent.

Above-mentioned by the agency of mistake, limit protrusion 42 of the elevating lever 4 of part on locating part 6 play switching function, The protrusion 42 is inserted into the through-hole of first sleeve 21.

In this example, the fixing piece 5 is equipped with multiple fixation holes 51.

Wherein, elevating lever 4 is arc, so that when pressing has the protrusion 42 of switching function, the protrusion of the other end Portion 42 can move back, so that the protrusion 42 skids off fixation hole 51, so that adjustable elevating lever 4 is gone up and down；Among the above, elevating lever 4 The upper part other side opposite with protrusion 42 is equipped with spring, so that the protrusion 42 of part can after being pressed on elevating lever 4 Rebound is gone back.

In this example, elastomeric element is equipped between the elevating lever 4 and support leg 3.

The elastomeric element plays miscellaneous function to the lifting of elevating lever 4, when the protrusion 42 of elevating lever lower part skids off fixation Hole 51, spring can bounce elevating lever 4, so that lighter to the height-regulating of elevating lever 4.

In this example, the elastomeric element includes spring.

Wherein, elastomeric element is not only chosen as spring, is also chosen as other elastomeric elements such as atmospheric pressure pole.

In this example, the balustrade panel 11 is the intermediate substantially straight reclinate arcuate structure in both ends.

Using this kind of balustrade panel 11, when handrail may make to be in appropriate height, 90 degree of elbow bends or so, hand naturally to Under, so that user obtains preferable support experience.

Specific embodiment of the utility model is described in detail above.It should be appreciated that those skilled in the art without It needs creative work according to the present utility model can conceive and makes many modifications and variations.Therefore, all the art Technical staff's the utility model design is available by logical analysis, reasoning, or a limited experiment in the prior art Technical solution, all should be in protection scope determined by the claims.
