Description
Technical field
The utility model is related to haulage vehicle technical field, more particularly to a kind of hand curtain rolling formula closed lorry body door.
Background technology
Van is general to set flat-open type car door behind compartment, and door leaf is to vehicle both sides when this car door is opened
Open, can not only take the car external space, and often generation passer-by or vehicle imprudence bump against the traffic thing of car door
Therefore, there is potential safety hazard.
Utility model content
The utility model overcomes the deficiencies in the prior art, and there is provided a kind of available roller shutter type van-type easily switched manually
Boxcar door, can avoid the problem of car door of traditional flat-open type is easily bumped against after opening by pedestrian or vehicle,
The utility model is achieved through the following technical solutions：
A kind of hand curtain rolling formula closed lorry body door, including rolling screen guiding rail, support, spool, reel, roller shutter and plane whirlpool
Coil spring；The rolling screen guiding rail is divided into both sides on rear side of compartment casing, and support is fixedly arranged on the compartment casing two above rolling screen guiding rail
Side, spool is fixedly connected between being located at support with support, and drum sheath is outside spool and spool rotates connection；The roller shutter by
The curtain sheet of multiple strips, which is hinged, to be in series, and the roller shutter is wrapped on reel and can slided up and down along rolling screen guiding rail；Institute
Plane scroll spring is stated in reel, one end of the plane scroll spring is fixedly connected with spool, the other end and mandrel interior wall
It is fixedly connected.
In use, when pulling with hand roller shutter closing car door, the hanging portion of roller shutter is elongated, the deadweight of its hanging portion also adds
Greatly, spool turns drive plane scroll spring to tighten up, the increase of its elastic force, the deadweight of roller shutter hanging portion and plane scroll spring
Elastic force is in poised state, and its transform gravitational energy is the elastic potential energy of plane scroll spring during roller shutter declines；Opening vehicle
During the door of railway carriage or compartment, roller shutter rises, and the deadweight of its hanging portion reduces, and reel drives plane scroll spring to follow diastole, and its elastic force reduces, volume
The deadweight of curtain hanging portion and the elastic force of plane scroll spring are still in poised state, in roller shutter uphill process, plane scroll bullet
The elastic potential energy of spring is converted into the gravitional force of roller shutter, as long as roller shutter is overcome between rolling screen guiding rail during raising and lowering
Frictional force, it is very light with hand switch car door.
Further, the reel is rotated by bearing and spool and connected.Spool turns can be made more smooth.
Further, protective cover is provided with outside the reel, the protective cover is in towards the streamlined of headstock direction.For protecting
Reel is from exposing to the weather, and fairshaped protective cover can reduce air drag when vehicle is travelled.
Further, the roller shutter bottom is provided with handle.It is easy to pull with hand roller shutter.
The beneficial effects of the utility model are：The car door that can avoid traditional flat-open type using the car door of roller shutter type is opened
The problem of easily being bumped against afterwards by pedestrian or vehicle, beneficial to traffic safety；Reel is arranged on vehicle exterior, is not take up interior empty
Between；Using plane scroll spring power-assisted spool turns, make hand switch car door very laborsaving.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the present utility model.
Fig. 3 is Fig. 2 A-A sectional views.
Embodiment
As shown in Figures 1 to 3, embodiment of the present utility model, a kind of hand curtain rolling formula closed lorry body door, including roller shutter
Guide rail 1, support 2, spool 3, reel 4, roller shutter 5 and plane scroll spring 6；The rolling screen guiding rail 1 is divided into the rear side of compartment casing 7
Both sides, support 2 is fixedly arranged on the both sides of compartment casing 7 of the top of rolling screen guiding rail 1, and spool 3 is fixed between being located at support 2 with support 2
Connection, reel 4 is enclosed on the outside of spool 3 and spool 3 rotates connection；The roller shutter 5 is hinged string by the curtain sheet 8 of multiple strips
Connection is formed, and the roller shutter 5 is wrapped on reel 4 and can slided up and down along rolling screen guiding rail 1；The plane scroll spring 6 is located at reel 4
Interior, one end of the plane scroll spring 6 is fixedly connected with spool 3, and the other end is fixedly connected with the inwall of reel 4.
In use, when pulling with hand the closing car door of roller shutter 5, the hanging portion of roller shutter 5 is elongated, the deadweight of its hanging portion
Increase, reel 4, which is rotated, drives plane scroll spring 6 to tighten up, the increase of its elastic force, the deadweight of the hanging portion of roller shutter 5 and plane scroll
The elastic force of spring 6 is in poised state, and its transform gravitational energy is the elastic potential of plane scroll spring 6 during roller shutter 5 declines
Energy；When opening car door, roller shutter 5 rises, and the deadweight of its hanging portion reduces, and reel 4 drives plane scroll spring 6 to follow diastole,
Its elastic force reduces, and the deadweight of the hanging portion of roller shutter 5 and the elastic force of plane scroll spring 6 are still in poised state, and roller shutter 5 rose
Cheng Zhong, the elastic potential energy of plane scroll spring 6 is converted into the gravitional force of roller shutter 5, as long as roller shutter 5 is during raising and lowering
Overcome the frictional force between rolling screen guiding rail 1, it is very light with hand switch car door.
In the present embodiment, the reel 4 is rotated by bearing 9 and spool 3 and connected.Reel 4 can be made to rotate more smooth.
In the present embodiment, the outside of reel 4 is provided with protective cover（It is not shown）, the protective cover is in the stream towards headstock direction
Line style.For protecting reel 4 from exposing to the weather, fairshaped protective cover can reduce air drag when vehicle is travelled.
In the present embodiment, the bottom of roller shutter 5 is provided with handle 10.It is easy to pull with hand roller shutter 5.
It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
