Abstract
The invention discloses a kind of door frame lifting assembly, including upper strut, lower supporting rod and connect assemblies for connecting two groups of upper and lower strut；The first connecting plate and the second connecting plate that connection assembly is differed by multiple length the most respectively form, and described first connecting plate and the second connecting plate are by resilient key and alignment pin interconnection successively, and form the quadrilateral structure that can stretch up and down；This door frame lifting assembly is also equipped with boatswain chair connecting pin on the two groups of connection assemblies be positioned at middle part, and arranges connection gusset in-between, so that coupled boatswain chair connecting pin is synchronized with the movement.The present invention, during using, utilizes the quadrilateral structure that can stretch up and down being made up of connecting plate to carry out up-down adjustment, and the door frame lifting assembly of this structure uses more convenient, safety, and then improves the service efficiency of fork truck；The connection gusset being simultaneously provided with can ensure that boatswain chair connecting pin uniform force, works simultaneously, and then ensures the connection component synchronization motion of both sides.
Description
Technical field
The present invention relates to a kind of portal-framed structure, be with being specifically related to a kind of apply on fork truck door frame lifting assembly.
Background technology
Mesh fork truck during being specifically applied to production assembling, the too high suspender belt that should not use of its door frame, the most easily produce danger, and the practical operation of inconvenient user.
Summary of the invention
For the technical problem of above-mentioned existence, it is an object of the invention to: propose a kind of apply on fork truck door frame lifting assembly.
The technical solution of the present invention is achieved in that a kind of door frame lifting assembly, including upper strut, lower supporting rod and connects assemblies for connecting two groups of upper and lower strut, and described connection assembly is symmetrically disposed in the left and right sides of strut and lower supporting rod；The first connecting plate and the second connecting plate that described connection assembly is differed by multiple length the most respectively form, and described first connecting plate and the second connecting plate are by resilient key and alignment pin interconnection successively, and form the quadrilateral structure that can stretch up and down；This door frame lifting assembly is also equipped with boatswain chair connecting pin on the two groups of connection assemblies be positioned at middle part, and arranges connection gusset in-between, so that coupled boatswain chair connecting pin is synchronized with the movement.
Further, described resilient key is horizontally through the first connecting plate and the contact site of the second connecting plate, and be positioned pin in its end spacing firmly；The end of described resilient key is also set with plain cushion, and described plain cushion is arranged on the inner side of alignment pin.
Further, described first connecting plate and the second connecting plate are additionally provided with copper sheathing on its contact site being connected.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
Door frame lifting assembly described in the present invention program is during specifically used, the left and right sides of upper strut is individually positioned in the channel-section steel of door frame left and right, then utilize the quadrilateral structure that can stretch up and down being made up of connecting plate below to carry out up-down adjustment, the door frame lifting assembly of this structure uses more convenient, safety, and then improves the service efficiency of fork truck；The connection gusset being simultaneously provided with can ensure that boatswain chair connecting pin uniform force, works simultaneously, and then ensures the connection component synchronization motion of both sides.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solution of the present invention is described further:
Accompanying drawing 1 is the front view of door frame lifting assembly of the present invention；
Accompanying drawing 2 is the A portion enlarged drawing of accompanying drawing 1；
Accompanying drawing 3 is the quadrilateral structure being made up of the first connecting plate and the second connecting plate in door frame lifting assembly of the present invention;
Wherein: 1, upper strut；2, lower supporting rod；3, assembly is connected；4, the first connecting plate；5, the second connecting plate；6, resilient key；7, alignment pin；8, boatswain chair connecting pin；9, gusset is connected；10, plain cushion；11, copper sheathing.
Detailed description of the invention
The present invention is described below in conjunction with the accompanying drawings.
Accompanying drawing 1-3 is a kind of door frame lifting assembly of the present invention, including upper strut 1, lower supporting rod 2 and connects assemblies 3 for connecting two groups of upper and lower strut, and described connection assembly 3 is symmetrically disposed in strut 1 and the left and right sides of lower supporting rod 2；The first connecting plate 4 and the second connecting plate 5 that described connection assembly 3 is differed by multiple length the most respectively form, and described first connecting plate 4 and the second connecting plate 5 are by resilient key 6 and alignment pin 7 interconnection successively, and form the quadrilateral structure that can stretch up and down；This door frame lifting assembly is also equipped with boatswain chair connecting pin 8 on the two groups of connection assemblies 3 be positioned at middle part, and arranges connection gusset 9 in-between, so that coupled boatswain chair connecting pin 8 is synchronized with the movement.
Wherein said resilient key 6 is horizontally through the first connecting plate 4 and contact site of the second connecting plate 5, and be positioned pin 7 in its end spacing firmly；The end of described resilient key 6 is also set with plain cushion 10, and described plain cushion 10 is arranged on the inner side of alignment pin 7；Described first connecting plate 4 is additionally provided with copper sheathing 11 with the second connecting plate 5 on its contact site being connected.
Door frame lifting assembly of the present invention is when specifically used, it is one group that the quantity of the scalability quadrilateral structure to be made up of the first connecting plate 4 and the second connecting plate 5 is 3, boatswain chair connecting pin 8 it is set and connects gusset 9, thus can ensure that two groups, set left and right connects assembly 3 and is synchronized with the movement.It is during specifically used, the left and right sides of upper strut 1 is individually positioned in the channel-section steel (not shown) of door frame left and right, then utilize the quadrilateral structure that can stretch up and down being made up of connecting plate below to carry out up-down adjustment, the door frame lifting assembly of this structure uses more convenient, safety, and then improves the service efficiency of fork truck；The connection gusset being simultaneously provided with can ensure that boatswain chair connecting pin 8 uniform force, works simultaneously, and then ensures that the connection assembly 3 of both sides is synchronized with the movement.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within the scope of the present invention.
