Abstract
The utility model relates to the field of transfer equipment, in particular to a universal caster frame. The device comprises a top plate, a bearing and two symmetrical caster frames, wherein an inner ring of the bearing protrudes upwards and is fixed on the bottom surface of the top plate; the top ends of the two foot wheel frames are respectively fixed at the positions, close to the edge of the excircle, of the bottom of the outer ring of the bearing; the lower ends of the two caster frames are respectively provided with a caster mounting hole. The utility model mainly comprises a top plate, a bearing and two symmetrical caster frames, wherein an inner ring of the bearing protrudes upwards and is fixed on the bottom surface of the top plate, a certain gap is reserved between an outer ring of the bearing and the bottom surface of the top plate, the bearing does not rub the top plate when rotating, the steering is more flexible, and the service life is longer.
Description
Technical Field
The utility model relates to the field of transfer equipment, in particular to a universal caster frame.
Background
At present, the caster is widely used in the aspects of trolleys, mechanical equipment, flat cars, warehouse carts, mobile scaffolds and the like, and comprises a movable caster, a fixed caster and a movable caster with a brake. The movable caster is also called universal caster, and a caster frame capable of rotating 360 degrees is matched with a single wheel, so that the caster can freely run in any direction. The truckle has the truckle of multiple material, like pp truckle, PVC truckle, PU truckle, cast iron truckle, nylon truckle, TPR truckle, iron core nylon truckle, iron core PU truckle etc..
The existing caster frame has the defects that the distance between a bearing and a top plate forming the caster frame is small, the bearing is easy to rub when rotating, the steering is not flexible, and the service life is short.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a universal caster frame to solve the technical problems.
In order to solve the problems, the technical scheme adopted by the utility model is as follows:
the utility model provides a universal truckle frame, includes roof, bearing and two symmetrical truckle frames which characterized in that: the inner ring of the bearing protrudes upwards and is fixed on the bottom surface of the top plate; the top ends of the two foot wheel frames are respectively fixed at the positions, close to the edge of the excircle, of the bottom of the outer ring of the bearing; the lower ends of the two caster frames are respectively provided with a caster mounting hole.
Furthermore, the center of the top plate is provided with a central through hole which is coaxial with the central hole of the bearing; and four vertex angle parts of the top plate are respectively provided with a fixed assembly hole.
Has the advantages that: compared with the prior art, the steering mechanism mainly comprises a top plate, a bearing and two symmetrical caster frames, wherein an inner ring of the bearing protrudes upwards and is fixed on the bottom surface of the top plate, a certain gap is reserved between an outer ring of the bearing and the bottom surface of the top plate, the bearing cannot rub the top plate when rotating, steering is more flexible, and the service life is longer.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The utility model is further described with reference to the following figures and detailed description.
Examples
Referring to fig. 1, the universal caster frame of the present embodiment includes a top plate 1, a bearing, and two symmetrical caster frames 3. The inner ring 21 of the bearing protrudes upwards and is fixed on the bottom surface of the top plate 1; the top ends of the two foot wheel frames 3 are respectively fixed at the positions, close to the edge of the excircle, of the bottom of the outer ring 22 of the bearing; the lower ends of the two caster frames 3 are respectively provided with caster mounting holes 31. A central through hole 12 which is coaxial with the central hole of the bearing is arranged at the center of the top plate 1; four vertex angle positions of the top plate 1 are respectively provided with a fixing assembly hole 11.
The universal caster frame mainly comprises a top plate 1, a bearing and two symmetrical caster frames 3, wherein an inner ring 21 of the bearing protrudes upwards and is fixed on the bottom surface of the top plate 1, a certain gap is reserved between an outer ring 22 of the bearing and the bottom surface of the top plate 1, and the bearing does not rub the top plate 1 when rotating, so that the steering is more flexible, and the service life is longer; moreover, the universal caster frame is integrally made of steel, so that the universal caster frame is high in bearing capacity, not prone to deformation and good in overall stability.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all equivalent structures made by using the contents of the specification and the drawings of the present invention can be directly or indirectly applied to other related technical fields, and are within the scope of the present invention.
