Abstract
The invention relates to a novel universal truckle. The universal truckle comprises a mounting plate, a rolling wheel and a rolling wheel bracket, wherein a connecting block is arranged between the mounting plate and the rolling wheel bracket, the connecting block is fixedly connected with the rolling wheel bracket at the lower end and movably connected with the mounting plate at the upper end in a way of relative rotating, and an adjusting locking buckle is arranged at the edge of the mounting plate. The novel universal truckle has an optimized structure, the locking device is arranged at the upper end of the universal truckle and enables the universal truckle to be fixed at a preset angle to achieve the exchange between a universal wheel and a fixed wheel, and therefore the novel universal truckle increases the flexibility of the use of a push cart when used on the push cart.
Description
Technical field
The present invention relates to a kind of castor, is a kind of novel universal castor specifically.
Background technology
Castor is divided into movable castor and rigid castors, and movable castor is also with regard to our said cardan wheel, and its structure allows 360 degree of rotations; Rigid castors does not have rotational structure, can not rotate.Normally two kinds of castors are all generally collocation use, and the structure of such as hand barrow is two, front tight pulley, and back is two movable cardan wheels near what promote handrail.The cardan wheel of back turns to for controlling, but when routine use, often encounter such problem, go-cart can because local narrow and small and cannot turn when turning, and when drawing go-cart, direction can be caused wayward instead, because front end is provided with tight pulley, also just cannot in the position go-cart of tight pulley because tight pulley and cardan wheel can not flexible conversion, cause the trouble of use.
Summary of the invention
For the problems referred to above of existing castor, the present invention designs a kind of novel universal caster wheel, and this universal caster wheel all can be installed in rear end, front end during use, this universal caster wheel can realize the conversion between tight pulley and cardan wheel, improves the alerting ability of go-cart.
Technical scheme of the present invention is: comprise adapter plate, roller and rolling wheel support, contiguous block is provided with between described adapter plate and rolling wheel support, the rolling wheel support of described contiguous block and lower end is for being fixedly connected with, be relatively turnable flexible connection with the adapter plate of upper end, described adapter plate edge is provided with adjustment snap close.
Described contiguous block is circular configuration, and contiguous block side is provided with some draw-in grooves.
The quantity of described draw-in groove is at least 4.
Described adjustment snap close comprises lock core, spring and lock tube, described lock core is placed in lock tube, lock core sleeve has spring, lock core front end is provided with stay bearing plate, for support spring, elastic force is produced to lock core, lock core rear end is provided with draw ring, and described lock tube front position is provided with cuts groove, described in cut groove and be divided into locking and cut groove and groove is cut in unblock.
Described locking is cut groove and unblock to cut groove is cross structure, lock cut groove cut groove depth be greater than unlock cut groove cut groove depth.
The invention has the beneficial effects as follows: the structure that present invention optimizes castor, a latching device is devised in cardan wheel upper end, this device can make cardan wheel be fixed on a predetermined angular, can realize changing between cardan wheel and tight pulley, thus when coordinating go-cart to use, add the alerting ability that go-cart uses.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of tight locking button of the present invention and contiguous block.
Fig. 3 is the structural representation of tight locking button of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in the figure 1, shown in 2 and 3: castor of the present invention comprises adapter plate 3, roller 1 and rolling wheel support 5, contiguous block 2 is provided with between adapter plate 3 and rolling wheel support 5, contiguous block 2 is welded as a whole with the rolling wheel support 5 of lower end, and be flexibly connected for relatively turnable with the adapter plate 3 of upper end, adapter plate 3 edge is provided with and regulates snap close 4.
Contiguous block 2 is circular configuration, and contiguous block side is provided with some draw-in grooves 6, the quantity of draw-in groove at least 4, also can design multiple to realize fixing multiple angle.
Snap close 4 is regulated to comprise lock core 8, spring 12 and lock tube 7, lock core 8 is placed in lock tube 7, lock core 8 overcoat has spring 12, lock core 8 front end is provided with stay bearing plate 13, produces elastic force for support spring to lock core, and lock core 8 rear end is provided with draw ring 10, lock tube 7 front position is provided with cuts groove, cut groove to be divided into locking and to cut groove 11 and groove 9 is cut in unblock, lock and cut groove 11 and cut groove 9 in cross structure with unblock, lock cut groove 11 cut groove depth be greater than unlock cut groove 9 cut groove depth.
During use, pull draw ring 10 to be with movable lock core 8 to be pulled outwardly, being admittedly stuck in by draw ring 10 locks when cutting in groove 11, relies on the elastic force of spring to be stuck in the draw-in groove 6 of contiguous block 2 lock core front end, and what realize castor is fixing, can use as tight pulley; During unblock, draw ring 10 is pulled out rear half-twist, make draw ring 10 fixedly be stuck in unblock and cut in groove 9, at this moment lock core 8 front end pull-out in draw-in groove 6, remove the locking to castor, castor is free to rotate, thus achieves cardan wheel and tight pulley is directly changed.
Claims (5)
1. a novel universal castor, comprise adapter plate, roller and rolling wheel support, it is characterized in that being provided with contiguous block between described adapter plate and rolling wheel support, the rolling wheel support of described contiguous block and lower end is for being fixedly connected with, be relatively turnable flexible connection with the adapter plate of upper end, described adapter plate edge is provided with adjustment snap close.
