Description
Technical field
The present invention relates to a kind of drag body, more precisely, relating to a kind of drag body for connecting transfer car(buggy) and working position apparatus.
Background technology
The quality of automobile body covering piece is particularly crucial for Automobile manufacturing, because its size is comparatively large, shape is more complicated, therefore need deposit with special utensil, needs to transport with fork truck or transport carriage in the circulation process of producing.
Because the point of connection of transport carriage is lower relative to the position on ground, therefore the point of connection on utensil, generally can not arrange too high, otherwise cannot mate with dolly point of connection and be connected.
Drag body of the prior art, is welded as a whole by tubular rotary sleeve and short connecting arm, is fixed on effect utensil played and connects dolly and utensil by adapter shaft and fixed hub; The connecting arm of this structure is shorter, and dolly and utensil connection procedure easily produce collision, and then have influence on the product design of blanked part in utensil.
Another structure is welded as a whole by tubular rotary sleeve and long connecting arm, is fixed on effect utensil played and connects dolly and utensil by adapter shaft and fixed hub; The connecting arm of this structure is longer, though ensure that the safety that utensil connects, when storage configuration, connecting arm due to Action of Gravity Field freely sagging, take more space, the fork of the laminated multi-layer and fork truck that affects utensil is transported.
Summary of the invention
The present invention, in order to solve problems of the prior art, provides a kind of drag body, effectively can solve the problem taken up room when long connecting arm is deposited.
In order to realize above-mentioned object, technical scheme of the present invention is: a kind of drag body, comprise spline stop part, the end face of described spline stop part is provided with adapter shaft, also comprise a rotary sleeve taking the shape of the letter U structure, the open end of described rotary sleeve is fixed with connecting arm, and described adapter shaft is through the U-lag of rotary sleeve; When rotary sleeve rotates to its sidewall and spline stop part end face less parallel around adapter shaft, the U-lag of described rotary sleeve has one section of path that can glide along adapter shaft for rotary sleeve on its bottom land to the direction of open end.
Preferably, described in take the shape of the letter U that the rotary sleeve of structure comprises that less parallel arranges first dull and stereotyped and second dull and stereotyped, and connect the first flat board, the second dull and stereotyped corresponding side and the curved connecting panel in cross section.
Preferably, described first flat board, the second flat board, connecting panel are formed by panel-bending.
Preferably, the U-lag open end of described rotary sleeve also has the position limiting structure preventing it from coming off from adapter shaft.
Preferably, described position limiting structure is through the bolt of the first flat board, the second flat board.
Preferably, described connecting arm is fixed between the first flat board and the second flat board, and described position limiting structure is the end that connecting arm extend between the first flat board and the second flat board.
Preferably, described adapter shaft is fixed on the end face of spline stop part by the fixed hub that its two ends are arranged.
Preferably, described spline stop part is the sidewall of working position apparatus.
When off working state, rotary sleeve can be rotated around adapter shaft, until make sidewall and the spline stop part end face less parallel of rotary sleeve, now, under the Action of Gravity Field of rotary sleeve and connecting arm self, or the power that artificial applying is certain, the U-lag of rotary sleeve can be made to glide along adapter shaft.Under slide to correct position after, part rotary sleeve being positioned at adapter shaft lower end and the part being positioned at adapter shaft upper end all can coordinate with the end face of spline stop part, rotate along adapter shaft 5 to prevent rotary sleeve.Thus avoid long connecting arm taking space.
Accompanying drawing explanation
Fig. 1 shows drag body of the present invention structural representation operationally.
Fig. 2 show drag body of the present invention fold after schematic diagram.
Detailed description of the invention
The technical matters solved to make the present invention, the technical scheme of employing, the technique effect easy to understand obtained, below in conjunction with concrete accompanying drawing, be described further the specific embodiment of the present invention.
With reference to figure 1, Fig. 2, a kind of drag body provided by the invention, comprises spline stop part 3, and should stop part 3 can be only one piece of flat board being fixed on working position apparatus, also can be the sidewall of working position apparatus.The end face of this spline stop part 3 is provided with adapter shaft 5, this adapter shaft 5 can be fix, also can be rotatably connected on the end face of spline stop part 3, leave between adapter shaft 5 and spline stop part 3 for installing the gap of rotary sleeve 2.
Adapter shaft 5 needs through rotary sleeve 2, and rotary sleeve 2 can be rotated along axle.Rotary sleeve 2 comprises the first dull and stereotyped 21 and second flat board 22 that less parallel is arranged, and connects the dull and stereotyped 22 corresponding sides of the first flat board 21, second and the curved connecting panel 20 in cross section, and this rotary sleeve 2 cross section is taken the shape of the letter U structure.
The open end of described rotary sleeve 2 is fixed with connecting arm 1, and adapter shaft 5 through the U-lag of rotary sleeve, and is fixed on the end face of spline stop part 3 by two fixed hubs 4; When needs towing, connecting panel 20 and the adapter shaft 5 of rotary sleeve 2 are combined together, thus realize the transport function of this drag body.
The U-lag of rotary sleeve 2 of the present invention has certain degree of depth, that is, the U-lag of rotary sleeve 2 has its path glided along adapter shaft 5 of one section of confession from its bottom land to its open end.Namely when off working state, rotary sleeve 2 can be rotated around adapter shaft 5, until make sidewall and the spline stop part 3 end face less parallel of rotary sleeve 2, now, under the Action of Gravity Field of rotary sleeve 2 and connecting arm 1 self, or the power that artificial applying is certain, the U-lag of rotary sleeve 2 can be made to glide along adapter shaft 5.Under slide to correct position after, part rotary sleeve 2 being positioned at adapter shaft 5 lower end and the part being positioned at adapter shaft 5 upper end all can coordinate with the end face of spline stop part 3, rotate along adapter shaft 5 to prevent rotary sleeve 2.Thus avoid long connecting arm taking space.
When needs use time, mentioned by connecting arm 1 together with rotary sleeve 2, until adapter shaft 3 is fitted with the connecting panel 20 (i.e. the bottom land of rotary sleeve) of rotary sleeve 2, now, rotatable rotary sleeve 2, couples together connecting arm 1 and transport carriage.
Preferably, the U-lag open end of described rotary sleeve 2 also has the position limiting structure preventing it from coming off from adapter shaft 5 in the present invention.This position limiting structure can be through bolt or the registration mast of the first flat board 21, second flat board 22.Can also be following structure: described connecting arm 1 is fixed between the first dull and stereotyped 21 and second flat board 22 by the mode of welding, and described position limiting structure is the end that connecting arm 1 extend between the first dull and stereotyped 21 and second flat board 22.
The present invention is by preferred embodiment having carried out detailed explanation.But, by studying carefully above, to the change of each embodiment with to increase also be that one of ordinary skill in the art institute is apparent.Being intended that all these changes and increasing of applicant has all dropped in scope that the claims in the present invention protect.
