Abstract
The utility model discloses a novel inserted bar type movable caster, which comprises a roller, an inserted bar and a support installed on the inserted bar, wherein outer curved trays and inner curvedtrays are mounted on the upper side and the lower side of the support, steel balls are installed between the support and each of the outer curved trays and between the support and each of the inner curved trays, first ball paths are arranged between the support and the outer curved trays, second ball paths are disposed between the support and the inner curved trays, and the steel balls are disposed inside the first ball paths and the second ball paths. The novel inserted bar type movable caster enables the roller to rotate flexibly, reduces noise, is durable, has long service life, and is suitable for being applied widely.
Description
Technical field
The utility model relates to a kind of castor, particularly a kind of inserted-link type movable castor.
Background technology
Along with science and technology development, castor becomes indispensable parts, has obtained using widely.The castor kind is numerous, and people invent out different caster wheeles and are applied among all trades and professions.Yet present inserted-link type movable castor but exists some problems.Support on the castor all is provided with a rolling ball track, and in use, rotates dumbly, and noise is bigger.Simultaneously because the bad castor that causes of rotation alerting ability is durable inadequately.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provide a kind of rotation flexibly, less, the long-lived novel inserted-link type movable castor of noise.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of novel inserted-link type movable castor, comprise roller, inserted link, be installed in the support on the described inserted link, the both sides up and down of described support are equipped with external wave dish and interior ripple dish, between described support and the external wave dish and between support and the interior ripple dish steel ball is installed, be provided with first rolling ball track between described support and the external wave dish, be provided with second rolling ball track between described support and the interior ripple dish, described steel ball places in first rolling ball track and second rolling ball track.
The beneficial effects of the utility model are: owing to be provided with first rolling ball track between support and the external wave dish, and be provided with second rolling ball track between support and the interior ripple dish, steel ball can roll within it, adopt the two rolling ball track structures of this kind can strengthen the rotation alerting ability of roller, reduced noise, thereby also more durable, prolonged service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a cross-sectional schematic of the present utility model.
The specific embodiment
With reference to Fig. 1, a kind of novel inserted-link type movable castor, comprise roller 7, inserted link 1, be installed in the support 2 on the described inserted link 1, the both sides up and down of described support 2 are equipped with external wave dish 3 and interior ripple dish 4, between described support 2 and the external wave dish 3 and between support 2 and the interior ripple dish 4 steel ball 5 is installed, be provided with first rolling ball track 6 between described support 2 and the external wave dish 3, be provided with second rolling ball track 8 between described support 2 and the interior ripple dish 4, described steel ball 5 places in first rolling ball track 6 and second rolling ball track 8, because be provided with first rolling ball track 6 between support 2 and the external wave dish 3, and be provided with second rolling ball track 8 between support 2 and the interior ripple dish 4, steel ball 5 can roll within it, adopt the two rolling ball track structures of this kind can strengthen the rotation alerting ability of roller 7, in use, rotate flexibly, reduced noise, thereby also more durable, prolonged service life.
Certainly, the invention is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
