Description
Technical field
The present invention relates to Hardware fitting technical field, especially relate to a kind of adjustable for height cardan wheel.
Background technology
Cardan wheel is widely used on comparatively large-scale case and bag, so that such case and bag can move easily.But in the time of ground relief, if the height of cardan wheel is lower, ground can break the bottom of case and bag.
Summary of the invention
The object of this invention is to provide a kind of adjustable for height cardan wheel, it has the advantages that to regulate easily according to service condition height.
The technical solution adopted in the present invention is: adjustable for height cardan wheel, comprise adapter plate, the bottom of this adapter plate is connected with wheel by swivel bearing, described adapter plate bottom is welded with the sleeve pipe that is vertical, the outside of this sleeve pipe is bolted with the non-rotatable lifting shaft that is inserted with of nut, internal clearance cooperation, and the lower end of this lifting shaft is fixed on the top of this swivel bearing; Simultaneously, the sidewall of this sleeve pipe is provided with a receiving opening, in this receiving opening, be provided with a steel ball, and at least 2 positioning pits that the sidewall of this lifting shaft is provided with and this steel ball matches, and the pass of the depth H of the diameter D of this steel ball, the wall thickness δ of sleeve pipe, positioning pit is: δ < D≤H+ δ.
The pass of the depth H of the diameter D of described steel ball, the wall thickness δ of sleeve pipe, positioning pit is: D=H+ δ.
The spring plate that sidewall outside is embedded with and this steel ball matches of described sleeve pipe.
The advantage that the present invention has is: can regulate easily height according to service condition.Adjustable for height cardan wheel of the present invention in use, only needs by rotary nut, and steel ball can inside and outsidely be moved, then make steel ball corresponding in different positioning pits, afterwards, again rotate this nut, steel ball cannot be moved, the height of this cardan wheel is regulated, very convenient.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the front views (semi-sictional view) of embodiments of the invention after adjustment completes;
Fig. 2 is the front view (semi-sictional view) that embodiments of the invention are in course of adjustment.
In figure: 10, adapter plate; 20, sleeve pipe, 21, receiving opening, 22, steel ball, 23, spring plate; 30, nut; 40, lifting shaft, 41, positioning pit; 50, swivel bearing; 60, wheel.
Detailed description of the invention
Embodiment, is shown in shown in Fig. 1 and Fig. 2: adjustable for height cardan wheel, comprises the adapter plate 10 of the bottom for be fixed on case and bag by screw.The bottom of this adapter plate 10 is connected with wheel 60 by swivel bearing 50.Further say, these adapter plate 10 bottoms are welded with the sleeve pipe 20 that is vertical.The outside of this sleeve pipe 20 is bolted with the non-rotatable lifting shaft 40 that is inserted with of nut 30, internal clearance cooperation.Such as, the inner chamber cross-sectional plane of this sleeve pipe 20 and the cross-sectional plane of this lifting shaft 40 are congruent polygon.The lower end of this lifting shaft 40 is fixed on the top of this swivel bearing 50.Meanwhile, the sidewall of this sleeve pipe 20 is provided with a receiving opening 21.In this receiving opening 21, be provided with a steel ball 22.At least 2 positioning pits 41 that the sidewall of this lifting shaft 40 is provided with and this steel ball 22 matches., this steel ball 22 can partly be stuck in this positioning pit 41 this lifting shaft 40 cannot be moved up and down.And, the diameter D of this steel ball 22, the wall thickness δ of this sleeve pipe 20, the pass of the depth H of this positioning pit 41 is: δ < D≤H+ δ.More excellent, the diameter D of this steel ball 22, the wall thickness δ of this sleeve pipe 20, the pass of the depth H of this positioning pit 41 is D=H+ δ.Like this, by rotating this nut 30, make the inside contact of these steel ball 22 these nuts 30 of discord, this steel ball 22 can be inside and outside mobile, then move up and down this lifting shaft 40, this steel ball 22 is entered in different positioning pit 41, then, again rotate this nut 30, this steel ball 22 is contacted with the inside of this nut 30, this steel ball 22 cannot move, and is then stuck in this positioning pit 41, and the height of this cardan wheel is line stabilization.That is to say, the height of this cardan wheel can regulate easily.
Further say the spring plate 23 that the sidewall outside of this sleeve pipe 20 is embedded with and this steel ball 22 matches.That is, the inside face of this spring plate 23 is against on this steel ball 22, has avoided this steel ball 22 in this receiving opening 21, to deviate from voluntarily, and is convenient to this steel ball 22 from being advanced in positioning pit 41.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification sheets of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
