Abstract
The utility model relates to a universal ball castor, comprising a ball, a casing, a plurality of rolling balls arranged between the ball and the casing and a stop mechanism arranged at the upper part of the ball. The rolling balls are arranged in spherical grooves at the of inner surface of the casing. The stop mechanism is mainly composed of a stop claw passing through the casing and an offsetting spring. After the stop claw moves down and contacts with the ball, the castor can be stopped. The castor is mainly used on household appliances or sofa.
Description
The utility model relates to a kind of spherical universal castor that does not have rotating shaft.
Existing universal caster wheel is the wheel shape castor that rotating shaft is arranged mostly.It has one can be equipped with a roller around the support of vertical pivot rotation on the transverse axis of support.But the radius of gyration of this class castor is bigger, thereby has influenced the alerting ability that rotates.Chinese patent CN87202299 discloses a kind of spherical universal castor, and it is made up of a spheroid, a housing, a retainer and some steel balls.Wherein retainer is provided with the hole, cave that some circles are placed steel ball.Because the steel ball number of this castor is more, all steel balls should touch with spheroid, should rotate flexibly in retainer again, and therefore higher to each other accuracy requirement of part, this can improve manufacturing cost undoubtedly.And the steel ball number too much also will influence the alerting ability that spheroid rotates, and particularly under the situation of load-bearing, spheroid easily is stuck.In addition, above-mentioned two class castors all do not have stop motion mechnism, and this does not wish just to seem not too convenient the household electrical appliance that are subjected to displacement or the furniture under some back in place or load-bearing condition.For example: laundry machine should not move after load-bearing, should not move after sofa is in place, and existing castor is not accomplished this point.
The purpose of this utility model provides a kind of the rotation flexibly and the spherical universal castor that can carry out stop easily.
One of solution that realizes the utility model purpose is: the spherical universal castor that is provided has a spheroid, housing, some ball and carriages that places between spheroid and the housing.Be provided with a stop motion mechnism of being made up of retaining pawl and retracing spring above spheroid, retaining pawl wherein passes through housing and is connected with carriage, and retracing spring is between carriage and housing.On a horizontal circumference of above-mentioned shell inner surface, be provided with three spherical grooves of placing ball at least.Load is delivered on the housing by carriage, retracing spring, is delivered on the spheroid by ball again.When castor moved, each ball rolled with spheroid.When load was light, retaining pawl did not contact with spheroid, and castor can move to any direction.Load increases, and retaining pawl moves down with carriage, and after load surpassed certain value, retaining pawl contacted with spheroid, with Castor stop.This class castor is mainly used in the article that promptly need stop after the load-bearing., can move arbitrarily when unloaded if after loading onto this kind castor as laundry machine; After injecting water, just can not move.
Realize the purpose of this utility model solution two be: the spherical universal castor that is provided has a spheroid, housing, some ball and carriages that is connected with housing that places between spheroid and the housing.Be provided with one above the spheroid by the retaining pawl that passes through housing, retracing spring be located at the stop motion mechnism that the jam nut on the carriage is formed.On a horizontal circumference of above-mentioned shell inner surface, be provided with three spherical grooves of placing ball at least.At ordinary times, retaining pawl does not contact with spheroid, and castor can move arbitrarily.When needing stop, as long as the rotational lock nut, the stop melon is moved down can be with Castor stop.This class castor is mainly used in and moves not frequent occasion.
Compared with prior art, great advantage of the present utility model is and can carries out stop easily, and in addition, the utility model adopts the spherical groove on the housing to come rotating bearing ball, and the number of ball is also less, thereby less to the constraint of spheroid, rotates more flexible.
Below in conjunction with accompanying drawing content of the present utility model is described in detail.
Fig. 1 is the constructional drawing of first solution of the utility model.
Fig. 2 is the another kind of constructional drawing of first solution.
Fig. 3 is the constructional drawing of second solution.
As shown in Figure 1: housing 1 usefulness steel plate is stamped to form.Also stamp out six uniform spherical grooves 2 on a horizontal circumference of housing 1 inside face, the inclination angle of the diad of this spherical groove is 45 °.Ball 3 places between spherical groove 2 and the spheroid 4.The top drilling of housing 1 also is welded with one and is with externally threaded guide pin bushing 6, and setting nut 5 is positioned at the lower end of guide pin bushing 6.Retaining pawl 9 passes through the top of guide pin bushing 6 and housing 1 and can slide up and down.The lower end of retaining pawl 9 is sphere and posts one deck friction material 10 that the upper end of retaining pawl 9 is connected with carriage 8 by nut 11.Stage clip 7 is between carriage 8 and setting nut 5.Carriage 8 fluctuates according to the size of its load-bearing, and retaining pawl 9 also slides up and down thereupon.After load that carriage 8 is born reached certain value, retaining pawl 9 just contacted with spheroid, with Castor stop.The ultimate load of Castor stop is regulated by setting nut 5 as required.
Fig. 2 has provided the another kind of form of stop motion mechnism.As shown in Figure 2, riveted a guide rod 13 at the top of housing 12, carriage 14 is enclosed within on the guide rod 13 and can slides up and down.Connected three retaining pawls 15 that pass through housing 12 on carriage 14, the lower end of retaining pawl 15 is a sphere, and between two balls.Stage clip 16 is between the setting nut 17 on housing 12 and the carriage 14.Three retaining pawls 15 also move with carriage 14, and after load that carriage bore surpassed certain value, retaining pawl 15 promptly contacted with spheroid, with Castor stop.The ultimate load of stop can be regulated by nut 17.
The structure of second solution of the utility model is as shown in Figure 3: housing 18 usefulness steel plates are stamped to form, go out six spherical grooves 19 within it on the surface, the inclination angle of the diad of each spherical groove 19 is 45 °, ball 20 is between spherical groove 19 and spheroid 21, carriage 22 is fixed together by screw rod 23 and housing 18, three retaining pawls 24 are fixed on the terminal pad 25, and they pass through housing 18 and are distributed in empty place between two balls.Reseting pressuring spring 26 is between housing 18 and terminal pad 25.Be provided with a jam nut 27 in the upper end of terminal pad 25.When needing stop, as long as rotational lock nut 27 moves down retaining pawl and touch spheroid 21 to get final product.
