Abstract
The utility model discloses a two ball universal wheel supports, include: fixing base and ball bear the tile, the ball bears the tile and sets up in the fixing base below, the ball bears and is provided with the first ball of round on the tile, be provided with first protection casing on the first ball, the fixed second protection casing that is provided with in first protection casing top, be provided with round second ball between second protection casing and the fixing base, the both sides of first protection casing one end are provided with downwardly extending's backup pad. In this way, two ball universal wheel supports, special design the cooperation of first ball and second ball support rotatory structure, rotatory stability is high, it is little rub, is favorable to the increase to bear, turns to more steadily, has improved life.
Description
Technical field
The utility model relates to castor field, particularly relates to a kind of two ball caster bracket.
Background technology
In order to conveniently moving, part furniture, household electrical appliances or seat bottom have been installed castor and have been promoted.Castor is mainly divided into directional wheel and cardan wheel, and directional wheel load-carrying capacity is strong, but can not at will turn, and the turning rate of cardan wheel is more flexible.
Because cardan wheel can realize turning to, Application comparison is extensive.Roll structure is enclosed in the many employings one of common cardan wheel, and friction is large, and load-carrying capacity is limited, poor durability, is easily damaged within go-cart service life, adds the expense of later maintenance.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of two ball caster bracket, reduces the friction turned to, improves load-carrying capacity and durability.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of two ball caster bracket, comprise: permanent seat and ball carrying watt, described ball carrying watt is arranged on below permanent seat, described ball carrying watt is provided with circle first ball, described first ball is provided with the first protective cover, the second protective cover is fixedly installed above described first protective cover, be provided with circle second ball between described second protective cover and permanent seat, the both sides of described first protective cover one end are provided with the stay bearing plate to downward-extension.
In the utility model preferred embodiment, between described ball carrying watt and permanent seat, rivet is adopted to be fixed.
In the utility model preferred embodiment, described stay bearing plate bottom is provided with roller fixed orifice.
In the utility model preferred embodiment, the both sides of described first protective cover are provided with the brace panel be connected with stay bearing plate.
In the utility model preferred embodiment, described first protection and the second protective cover rotate under the support of the first ball and the second ball.
The beneficial effects of the utility model are: the two ball caster bracket of one that the utility model is pointed out, devise the structure of the first ball and the second ball engagement support rotation especially, the stability of rotation is high, rub little, be conducive to increasing carrying, turn to more steady, improve service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of the utility model a kind of pair of ball caster bracket one preferred embodiment.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, the utility model embodiment comprises:
A kind of two ball caster bracket, comprise: permanent seat 1 and ball carrying watts 2, described ball carrying watts 2 is arranged on below permanent seat 1, described ball carrying watt adopts rivet 3 to be fixed between 2 and permanent seat 1, Joint strenght is high, ball carrying watts 2 is fixed on the bottom of go-cart with permanent seat 1, ensure that overall structural strength.
Described ball carrying watts 2 is provided with circle first ball 7, described first ball 7 is provided with the first protective cover 4, the second protective cover 5 is fixedly installed above described first protective cover 4, circle second ball 6 is provided with between described second protective cover 5 and permanent seat 1, the both sides of described first protective cover 4 one end are provided with the interval leaving roller between stay bearing plate 8, two stay bearing plates 8 to downward-extension.
Described stay bearing plate 8 bottom is provided with roller fixed orifice 81.By roller fixed orifice 81, be conducive to the Assembly &Disassembly of roller.
The both sides of described first protective cover 4 are provided with the brace panel 9 be connected with stay bearing plate 8, and brace panel 9 improves the Joint strenght of stay bearing plate 8 and the first protective cover 4, are conducive to the load-carrying capacity improving two ball caster bracket entirety.
Described first protection 4 and the second protective cover 5 rotate under the support of the first ball 7 and the second ball 6.What the first protection 4 and the second protective cover 5 combined is all friction of rolling up and down, and friction force is little, smooth running, is conducive to improving load-carrying capacity.
In sum, the two ball caster bracket of one that the utility model is pointed out, the good stability turned to, rubs little, and load-carrying capacity is strong, is applicable to coordinating with multiple roller making cardan wheel, is conducive to improving its service life.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
