Abstract
The utility model discloses a height bears truckle, include: fixed plate, fixing base and rotation seat, the fixing base sets up the lower surface at the fixed plate, rotate and to be provided with first bearing between seat and the fixing base and to be connected, it is provided with the drum that extends to the fixing base top perpendicularly to rotate the seat middle part, the fixing base middle part is provided with the ladder hole that supplies the drum to pass through, the downthehole cover that is provided with is established at the outside second bearing of drum in the ladder, rotation seat below is provided with the support riser of two symmetries, it is provided with a gyro wheel to support between the riser. In this way, height bears truckle, adopted the cooperation of first bearing and second bearing to realize turning to very much, both improved rotatory flexibility and antitorque intensity, can improve bearing capacity again, the truckle durability of making is better, is difficult for breaking occur in the use.
Description
Technical field
The utility model relates to castor field, particularly relates to a kind of high-mechanic castor.
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, and the anti-twisting property of rotational structure is poor, easily in use ruptures.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of high-mechanic castor, improves load-carrying capacity and torsional strength.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of high-mechanic castor, comprise: adapter plate, permanent seat and rotation seat, described permanent seat is arranged on the lower surface of adapter plate, described rotation seat is arranged on the below of permanent seat with one heart, described rotation seat be provided with clutch shaft bearing between permanent seat and be connected, the cylinder extended perpendicularly to above permanent seat is provided with in the middle part of described rotation seat, the ladder endoporus passed through for cylinder is provided with in the middle part of described permanent seat, the second bearing being set in cylindrical outer is provided with in described ladder endoporus, two symmetrical support risers are provided with below described rotation seat, a roller is provided with between described support riser, described roller comprises irony wheel hub and is coated on the polyurethane wear resistant layer on irony wheel hub cylindrical.
In the utility model preferred embodiment, described rotation seat with permanent seat is respectively arranged with the groove corresponding with clutch shaft bearing.
In the utility model preferred embodiment, described clutch shaft bearing is thrust ball bearing, and described second bearing is tapered roller bearing.
In the utility model preferred embodiment, described cylinder and rotation seat are punching press integral structure.
In the utility model preferred embodiment, described cylinder cylindrical top is provided with screw thread, described cylinder is provided with a clamp nut.
The beneficial effects of the utility model are: a kind of high-mechanic castor that the utility model is pointed out, the cooperation that have employed clutch shaft bearing and the second bearing especially realizes turning to, both the alerting ability of rotation and antitorque intensity had been improve, load-carrying capacity can be improved again, the castor durability made is better, not easily in use ruptures.
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 a kind of high-mechanic castor one of the utility model 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 high-mechanic castor, comprising: adapter plate 1, permanent seat 2 and rotation seat 3, described permanent seat 2 is arranged on the lower surface of adapter plate 1, and employing is weldingly connected, sound construction, not fragile.
Described rotation seat 3 is arranged on the below of permanent seat 2 with one heart, described rotation seat 3 be provided with clutch shaft bearing 6 between permanent seat 2 and be connected, described rotation seat 3 is respectively arranged with the groove corresponding with clutch shaft bearing 6 with on permanent seat 2, described clutch shaft bearing 6 is thrust ball bearing, rotation seat 3 is made to be able to rotate below permanent seat 2, the load-carrying capacity of thrust ball bearing is large, is conducive to the bearing capacity improving castor.
The cylinder 31 extended perpendicularly to above permanent seat 2 is provided with in the middle part of described rotation seat 3, the ladder endoporus passed through for cylinder 31 is provided with in the middle part of described permanent seat 2, the second bearing 7 being set in cylinder 31 outside is provided with in described ladder endoporus, described second bearing 7 is tapered roller bearing, the outer wall of cylinder 31 and the inner hole wall of the second bearing 7 fit, improve the torsional property of castor, and improve the stability turned to, not easily rupture in steering procedure.
Two symmetrical support risers 4 are provided with below described rotation seat 3, a roller 5 is provided with between described support riser 4, described roller 5 comprises irony wheel hub and is coated on the polyurethane wear resistant layer on irony wheel hub cylindrical, the wide 76mm of roller 5, increase area of thrust surface, improve load-carrying capacity, sound construction, and the resistance to abrasion of polyurethane wear resistant layer is good, more durable.
Described cylinder 31 and rotation seat 3 are punching press integral structure, and sound construction, production efficiency is high, with low cost.
Described cylinder 31 cylindrical top is provided with screw thread, described cylinder 31 is provided with a clamp nut 8, and clamp nut 8 is fixed on the second bearing 7 between cylinder 31 and ladder endoporus.
In sum, a kind of high-mechanic castor that the utility model is pointed out, load-carrying capacity is large, and antitorque ability is strong, turns to flexibly, uses more stable, not easily breakage problem occurs, improve life-span and the safety of use.
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.
