Description
Technical field
The utility model belongs to trolley wheel, is specifically related to a kind of special-purpose wheel of ramp formula elevator that is exclusively used in.
Background technology
Existing supermarket shopping car caster wheel does not have brake equipment, during up and down ramp formula elevator, normally realizes its braking and parking function by the back-up block that is installed in the wheel both sides.And this class castor is subjected to its structural constraint generally to adopt hard material to make, and therefore vibration is big when carrying out, and noise is big.
Summary of the invention
The purpose of this utility model be to provide a kind of can be at the wheel of ramp formula elevator autobrake and Parking, to overcome above-mentioned deficiency.
The technical solution of the utility model is: the special-purpose wheel of ramp formula elevator, and it comprises support, and support connects axletree, and axletree connects wheel hub, connects wheel rim on the wheel hub, makes moving ring gear on the spoke face of wheel hub, establishes breaker slot on the braking ring gear; Be connected with the banking pin that can move relative to breaker slot in the breaker slot, connect locating bush on the wheel shaft of wheel hub, locating bush connects the braking terminal pad that can move with respect to locating bush, and the other end of banking pin connects the braking terminal pad, connects the interlock ring on the braking terminal pad.
Described braking force control system comprises the guide groove of establishing in the braking terminal pad, establishes spring in the guide groove, and the other end of spring contacts with locating bush.
When this wheel uses, interlock ring and wheel rim land simultaneously, rotate with wheel rim, when up and down ramp formula elevator, when the interlock ring runs into the tread groove of ramp formula elevator, can under the effect of return spring, descend, drop in the tread groove, this moment, banking pin moved in the breaker slot, thereby blocked wheel hub, realized braking and Parking.Its dependable performance, simple for structure, of many uses, shockproof noiselessness.Be applicable to braking and the Parkings of hand barrow on the formula elevator of ramp such as baggage car, shopping cart, tote cart, perambulator, stretcher.
