Abstract
The utility model discloses a waterproof and anti-collision swivel caster and belongs to the technical field of ordinary casters. The waterproof and anti-collision swivel caster comprises an upper cover plate, a main shaft, a surface bearing, a support and a wheel, wherein the upper cover plate is connected with the support in a rotary mode through the surface bearing, and the support is connected with the wheel through a bolt and a nut. The waterproof and anti-collision swivel caster further comprises a waterproof cover and an anti-collision structure, wherein the waterproof cover is arranged inside the support and under the surface bearing, and the periphery of the waterproof cover is connected with the underside of the surface bearing in a sealed mode. The anti-collision structure comprises two pieces of steel plate in a semi-circle flake shape which are respectively arranged at two sides of the bottom of the support and combined with the support to form a whole structure. The circle center of the steel plates in a semi-circle flake shape is consistent with the axle center of the main shaft. Compared with the prior art, the waterproof and anti-collision swivel caster has the advantages of being waterproof and anti-collision, wherein the waterproof function prevents water from being carried to the inside of the surface bearing by the wheel, and therefore rust of the surface bearing is avoided, and the rotary connection between the upper cover plate and the support is ensured; the anti-collision function prevents the caster from being collided, and therefore damage to the swivel caster from being frequently collided is avoided, and the service life of the swivel caster is prolonged.
Description
Technical field
The utility model is a kind of universal caster wheel, and particularly a kind of waterproof, crashproof universal caster wheel belong to general castor technical field.
Background technology
Universal caster wheel is a kind of object bottom of being installed in, and makes it to be convenient to mobile parts, is widely used in the products such as go-cart, casing, seat, for people at home, the fields such as travelling, medical treatment are indispensable.Existing universal caster wheel generally has two kinds, and a kind of is universal caster wheel with upper cover plate, during installation, is to be fixed on the object with the upper cover plate of 2-4 bolt with universal caster wheel; Another kind during installation, is in the screw rod insertion go-cart base plate mounting hole with main shaft with the universal caster wheel of main shaft, uses nut screwing clamping.No matter be the sort of universal caster wheel, in use, when process had the ground of water, it is inner that wheel is easy to that water is brought into surface bearing, so just causes the surface bearing inner inlet to get rusty easily, so that universal caster wheel damages, the life-span reduces.No matter and be the sort of universal caster wheel, in use, wheel often bumps with the object such as wall, so just causes easily the castor damage, the life-span minimizing.
The utility model content
The purpose of this utility model is in the above-mentioned prior art, the universal caster wheel wheel is easy to that water is brought into surface bearing inside and causes and get rusty, wheel is often collided, cause easily castor to damage, the defective that the life-span reduces provides a kind of waterproof universal caster wheel, can reach wheel can not bring water surface bearing inside into, not cause and get rusty, wheel can not collided, so that universal caster wheel does not damage the purpose that increases the service life
The technical scheme taked of the utility model is to achieve these goals: a kind of waterproof, crashproof universal caster wheel, comprise upper cover plate, main shaft, surface bearing, support and wheel, and described upper cover plate is rotationally connected by surface bearing and support; Described support is connected by bolt, nut with wheel, also comprises watertight cover and collision protection structure, and described watertight cover is arranged in the support, the surface bearing below, and the watertight cover periphery is tightly connected below surface bearing; Described collision protection structure comprises 2 blocks of semicircle sheet steel plates, is separately positioned on the frame bottom both sides, is structure as a whole with support.
Described surface bearing comprises steel loop, upper steel ball group, middle steel loop, lower steel ball group and lower steel loop, described upper cover plate is captiveed joint with main shaft by the upper steel loop of surface bearing, described middle steel loop is captiveed joint with the support upper end, described watertight cover is below lower steel loop, and the watertight cover periphery is connected with glue sealing with middle steel loop bottom.
The center of circle of the semicircle sheet steel plate of described collision protection structure is consistent with spindle axis.Compared with prior art, the beneficial effects of the utility model are:
(1) waterproof, wheel can not bring water into surface bearing inside, avoid surface bearing to get rusty, and have guaranteed that upper cover plate and support are rotationally connected.
(2) prevent that castor from being collided, avoided universal caster wheel to be damaged because often colliding, prolonged the service life of universal caster wheel.
