Description
Technical field
The present invention relates to rail vehicle braking technical field, particularly a kind of rail vehicle is hand braking with telescopic foldable
Formula brakes crank.
Background technology
Passenger train brakes is generally divided into air damping and hand braking, wherein hand braking is by artificially rotating system
Shake come what is realized, i.e., realized by manpower.Existing hand braking crank, as shown in figure 1, length is longer, and length can not
Regulation, for staff in operation, amplitude of rolling over is very big, and turnning circle is more, very inconvenient using operating, and specifically deposits
In following weak point：
(1) crank length is a fixed value, it is impossible to adjusts the suitable arm of force according to personal firmly custom, physical difference
Size.
(2) because crank is longer, slewing area is larger, in the case of crank stress very little, rotates very inconvenient.
(3) profile is larger, takes up space big, is influenceed for outward appearance angle attractive in appearance.
The content of the invention
In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a kind of rail vehicle is hand-made
Telescopic foldable formula braking crank, adjustable length of the present invention are employed, staff can select according to own characteristic when in use
Suitable crank length.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of rail vehicle is hand braking to brake crank, including swingle with telescopic foldable formula, positioned at swingle side
Be provided at both ends with hand handle, offer chute inside the both ends of the swingle, slided in chute and be provided with slide bar, crank is set
In on slide bar, slide bar can slide together with hand handle in chute, and slide bar be located at chute one end be provided with prevent its from
The stopper to be come off in chute；The hand handle is articulated with slide bar, can be rotated around hinge, with rotating rod in rotation process
Into two kinds of relative position states：Hang down perpendicular and parallel；And during parallel rotating, rotated towards swingle internal direction, hand handle is folded
To swingle side.
The slide bar equal length at swingle both ends is preferably located at, i.e. stroke of the hand handle at both ends in chute is equal.
Further, it is hinged on slide bar at hand handle and is provided with a semicircle swivelling chute, semicircle rotation channel opening court
To swingle inside, for limiting the direction of rotation of hand handle.
It is preferred that hand handle has a rotating shaft, the rotating shaft is articulated with slide bar by hinge, and spring is arranged with rotating shaft.
After the present invention uses said structure, have the following technical effect that：
The present invention into can adjust, can select the Design of length of swingle properly according to the space size of operating environment
Length；Regulation rotation pole length, changes handle rotation radius, can make the rotation of hand handle become more flexible and convenient, can basis
Personal considerations select the swingle of appropriate length, and use is more comfortable, efficiently；Because swingle can stretch, hand handle can
Fold, save space, from the appearance from the point of view of, it is also more attractive in appearance.
Brief description of the drawings
Fig. 1 is the structure of hand braking crank in the prior art.
Fig. 2 is the overall structure of the present invention.
Fig. 3 is the structure that crank is folded to swingle side.
Fig. 4 is that stroke of the crank in chute is maximum, and crank is perpendicular to the structure of swingle.
Embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention..
As shown in Fig. 2 a kind of rail vehicle is hand braking to brake crank, including swingle 4 with telescopic foldable formula, it is located at
The side of swingle 4 is provided at both ends with hand handle 1, it is characterised in that：Chute 3, chute are offered inside the both ends of the swingle 4
To be slided in 3 and be provided with slide bar 2, hand handle 1 is arranged on slide bar 2, and slide bar 2 can slide together with hand handle 1 in chute 3, and
One end that slide bar 2 is located at chute 3 is provided with the stopper for preventing that it from coming off out of chute 3；
As shown in Figure 3,4, the hand handle 1 is articulated with slide bar 2, can be rotated around hinge, in rotation process with rotation
Bar 4 forms two kinds of relative position states：Hang down perpendicular and parallel；And during parallel rotating, rotated towards the internal direction of swingle 4, by hand
The side of swingle 4 is folded to 1.
The equal length of slide bar 2 positioned at the both ends of swingle 4, i.e. stroke of the hand handle 1 at both ends in chute 3 are equal.It is existing
The length of swingle is commonly used for 360mm in technology, and present invention design respectively has 40mm stroke, i.e. this kind of structure at swingle both ends
80mm space can be saved.In use, by the stretched chute of slide bar, specific tensile elongation can be maximum according to personal habits, both ends
It is stretchable to 40mm so that the overall length of whole swingle is 360mm, and now, the moment of torsion that can apply reaches maximum., will during reset
In slide bar push-in chute, swingle is contracted to most short position, i.e., now length is 280mm.Therefore total degree of swingle can be with
Adjusted between 280mm~360mm.
It is hinged on slide bar 2 at hand handle 1 and is provided with a semicircle swivelling chute 5, semicircle rotation channel opening direction rotation
Inside bar 4, for limiting the direction of rotation of hand handle 1.
Hand handle 1 has a rotating shaft, and the rotating shaft is articulated with slide bar 2 by hinge, in order in use, being used to hold hand handle
It is more comfortable during power, the sheathed spring in rotating shaft, spring outside cladding sponge.
One of the present invention uses embodiment：
, it is necessary to rotate clockwise the circle of hand handle about 25 during braking.Be characterized in preceding 20 circle, it is necessary to torque very little, most
Afterwards during 5 circle, brake force gradually increases, and the torque for rotating crank is also required to become larger, so, can be according to individual from figure
The difference of part, firmly custom, when preceding 20 enclose, the swingle of minimum length is selected, when last 5 enclose, selects swingle as most
Long length.
, it is necessary to rotate counterclockwise the circle of hand handle about 25 during alleviation.It is characterized in that preceding 5 circle needs torque larger, rear 20 circle needs
Torque very little.So can be in preceding 5 circle selection swingle maximum lengths, rear 20 circle selection swingle minimum length.
Telescopic hand braking crank makes operation simpler effectively, and operating personnel can be helped to save strength, and not shadow
Ring brake force size.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
