Specific implementation mode

The utility model is further described specifically with reference to embodiment and attached drawing：

Such as Fig. 1, shown in Fig. 2, a kind of rotatable vertical handrail, whole axisymmetricly structure, including 3 handle portions and Connection structure for disposing the handle portion；The connection structure includes：It is vertically connected with bar 1,7, stem 9 is rotated up and down cap 2,5 and upper and lower shifting part 10,8, described to be vertically connected with bar 1,7, stem 9, is rotated up and down cap 2,5 and upper and lower shifting part 10,8 is same Axis；

Described to be vertically connected with bar 1,7, the upper and lower ends for being located at connection structure are used for the vertical handrail in compartment Vertical fixed, as shown in Figure 3 and Figure 4, upper connecting rod 1 is connected to the horizontal cross bar 100 on the top in compartment, and lower connecting rod 7 connects Floor 200 in compartment；

The stem 9, be threadedly connected to it is described be vertically connected between bar 1,7, for disposing the handle portion, its underpart Guide pin 4 and spring button 6 is respectively set, the two protrudes from the external peripheral surface of stem 9 respectively；The spring button 6 by Pressure effect pushes not within the external peripheral surface of the stem 9, when without pressing force effect, then in elastic recovery force effect Under bounce and other than protruding from the external peripheral surface of the stem 9；When the vertical handrail Unscrew, the lower turncap 5 rotate with the handle portion that the rotation of upper turncap 2 is driven, and drive 8 leading in the guide pin 4 of the lower shifting part The spring button 6 is slipped over from bottom to top to stem 9 described in effect lower edge, when the lower shifting part 8 slides entirely over the spring After button 6, the latter's pop-up simultaneously supports the lower shifting part 8 and lower turncap 5 in 8 bottom of lower shifting part, such as Fig. 8 institutes Show；The handle portion also reaches maximum unfolded state namely use state at this time, as shown in Figure 4；

It is described be rotated up and down cap 2,5 respectively with it is described up and down shifting part 10,8 with merge can respectively relatively up and down shifting part 10,8 rotations；The cap 2,5 that is rotated up and down is hinged with the upper and lower side of the handle portion respectively；The upper shifting part 10 and the core Column 9 is integrally machined and the relatively described stem 9 is fixed, and entirety is in the form of a column, and top is cylindric, and lower part is curl regular triangular prism Shape, the curl are interior concave arc, as shown in Figure 5；The lower shifting part 8 is placed on 9 lower part of the stem, can be in the stem 9 The guide pin 4 of lower part is oriented to stem 9 described in lower edge and moves up and down, the lower shifting part 8 can be used the processing of rigid plastics material and At whole is in open column shape, and top is hollow cylindrical, and lower part is hollow curl regular triangular prism shape, and the curl is justified for indent Arc, as shown in Figure 6.

The handle portion includes 3 hinged wing plate monomers 3 successively, is respectively its number from top to bottom for convenience of describing It is sequentially hinged for I, II, III, 3 wing plate monomers of wing plate monomer, as shown in Fig. 7 or Fig. 2, the wherein upper end of wing plate monomer I and the wing The lower end of plate monomer III respectively be rotated up and down cap 2,5 and be hinged, as shown in Fig. 8 or Fig. 2.It is in non-in the vertical handrail When under use state, i.e., when the wing plate monomer 3 is not opened, the handle portion is integrally of a straight line type fitting 9 surface of stem And entirety is in the form of a column, and is first not take up space, the rail post that second can be used as a routine is convenient for passenger directly hand steered, such as Fig. 1 Shown in Fig. 3.And when the handrail or handle deficiency in compartment, when the vertical handrail needs to enter use state, pass through rotation Turn upper turncap 2 and so that the wing plate monomer 3 is gradually opened in rotary course, so as in the same upright position of stem On be formed simultaneously 3 handle portions, each handle portion is opened by 3 wing plate monomers being hinged and is formed, such as Fig. 2 and Fig. 4 It is shown.

It is provided with elastic tape, the rubber between the lower end and upper shifting part 10 that 9 top of the stem is located at upper connecting rod 1 Apron coordinates with stem transition.

The operation principle of the rotatable vertical handrail is as follows：

Rotatable vertical handrail opening procedure and use state：The rotatable vertical handrail is mounted on subway In compartment, such as Fig. 3, shown in Fig. 4, upper connecting rod 1 is connect with the horizontal cross bar 100 on subway carriage top, and lower connecting rod 7 connects On the floor 200 in compartment.When the handle deficiency in compartment, turncap 2 only need to be rotated in certain direction, and is passed through with it The hinged wing plate monomer I of tack screw and hinged successively wing plate monomer II, III are also rotated therewith and simultaneously to far from cores The central axes direction of column 9 outwardly opens；Descend turncap 5 as wing plate monomer III hinged therewith is stirred along under described at this time Part 8 rotates and the lower shifting part 8 is driven to move up certain distance under the guiding role of the guide pin 4, in this process In lower shifting part 8 touch and compress built-in spring button 6, until the latter is pressed within 9 circumferential surface of the stem, under described Shifting part 8 moves up after the spring button 6, the latter's pop-up, at this point, the handle portion, which also reaches it, opens dominant bit It sets, that is, completes handrail opening action and enter use state, as shown in Figure 4.Passenger can catch wing plate, to ensure and improve The safety and comfort level that passenger rides.

Rotatable vertical handrail closing process：Within non-rush hour or compartment under the state enough such as intrinsic handrail, The rotatable vertical handrail opened can be closed, at this time, it is only necessary to hold lower turncap 5 while press the bullet of stem lower part Spring button 6, then without the rest of the spring button 6, lower turncap 5 and lower shifting part 8 etc. are the effect started in gravity It is lower to be moved downward along guide pin 4；At the same time, the wing plate monomer hinged with lower turncap 5 or handle portion also side in the same of rotation When move down and drive that hinged upper turncap 2 rotates therewith above, until the wing plate monomer or its handle constituted Portion, which integrally stretches and is bonded or coincide with the stem surface, becomes smooth curved surface, and the rotatable vertical handrail described at this time closes It closes, handle portion is in non-working condition.

The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not It is confined to this, any one skilled in the art is in the technical scope that the utility model discloses, according to this practicality Novel technical solution and its technical concept is subject to equivalent substitution or change, should all cover the scope of protection of the utility model it It is interior.
