[utility model content]
The utility model purpose is to have overcome the deficiencies in the prior art and shopping cart elevator castor that a kind of simple in structure, good braking effect is provided.
In order to solve the technical matters of above-mentioned existence, the utility model adopts following technical proposal:
Shopping cart elevator castor, include trundle bracket and the single-wheel that is installed on the trundle bracket, one axle sleeve passes the mounting hole of trundle bracket and the centre hole of single-wheel respectively, one bolt passes axle sleeve and is connected on the trundle bracket by nut, it is characterized in that also including a slide block, be fixedly connected with adapter shaft in the slide block lower end, adapter shaft is provided with a rotating brake wheel, be provided with a slide opening in the upper end of slide block, be provided with a friction lining on slide block the right, axle sleeve is passed in the hole of described friction lining, is provided with spring between axle sleeve and slide opening bottom.
Aforesaid shopping cart elevator castor is characterized in that being provided with a cover of dust at a side of single-wheel, and this cover of dust is connected on the axle sleeve, is provided with arc port in the cover of dust bottom, and the first half of described brake wheel places under the arc port.
Aforesaid shopping cart elevator castor, it is characterized in that described axle sleeve includes the middle support portion and the connecting portion on both sides, on the support portion, be arranged with backup bearing, the rotation section of backup bearing outside is arranged in the centre hole of single-wheel, described connecting portion is a square, the square opening that matches with connecting portion in described mounting hole and hole.
Aforesaid shopping cart elevator castor, it is characterized in that described slide opening can be divided into movable part that is located at the first half and the elastic portion that is located at lower part, the aperture of movable part is bigger than the aperture of elastic portion, and described friction lining is arranged on the movable part, and described spring is arranged on the elastic portion.
Aforesaid shopping cart elevator castor is characterized in that being provided with an inserting column on elastic portion, insert in the inserting column lower end of described spring.
The utility model compared with prior art has following advantage: the utility model adopts castor to be provided with a slide block, be provided with brake wheel in the slide block lower end, be provided with friction lining in upper end of slide block, friction lining is fixed on again on the axle sleeve, is provided with in slide block and can adorns the spring that axle sleeve up pushes up.When castor was shifted onto on the ordinary telegram ladder, brake wheel made brake wheel snap in the groove of ordinary telegram ladder under the effect of spring force like this, drove slide block to lower slider, and the front end of slide block snaps in the single-wheel teeth groove, plays the effect of braking.This is simple in structure, practicality and rotating effect are good.
Have again the utility model also have load-carrying big, durable, turn to flexibly, characteristics such as brake is stable, price is low.

[specific embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail:
Shopping cart elevator castor as shown in the figure, includes trundle bracket 1 and is installed in caster wheel 2 on the trundle bracket 1.One axle sleeve 4 passes the mounting hole 11 of trundle bracket 1 and the centre hole 21 of castor 2 respectively, and a bolt 3 passes axle sleeve 4 and is connected on the trundle bracket 1 by nut afterwards, realizes castor 2 is installed on the trundle bracket 1.Specifically, the support portion 41 in the middle of described axle sleeve 4 includes and the connecting portion 42 on both sides.Be arranged with backup bearing 11 on support portion 41, the rotation section of backup bearing 11 outsides is arranged in the centre hole 21 of single-wheel 2.Described connecting portion 42 is a square, the square opening that matches with connecting portion 42 in described mounting hole 11 and hole 81.
In addition, realize braking function in order to realize shopping cart elevator castor, described shopping cart elevator castor also includes a slide block 5.Be fixedly connected with adapter shaft 6 in slide block 5 lower ends, adapter shaft 6 is provided with a rotating brake wheel 7.Be provided with a slide opening 51 in the upper end of slide block 5, be provided with a friction lining 8 at slide block 5 sides.The hole 81 of described friction lining 8 is passed axle sleeve 4 and is fixed on the axle sleeve 4.Between axle sleeve 4 and slide opening 51 bottoms, be provided with spring 9.Under the elastic force effect of spring 9, spring 9 turns down slide block 5 like this, makes slide block 5 toward lower slider, makes brake wheel 7 also and then move down, and the bottom of brake wheel 7 is also lower than the bottom of castor 2 like this.
Side at castor 2 is provided with a cover of dust 10, and this cover of dust 10 is connected on the axle sleeve 4, is provided with arc port in cover of dust 10 bottoms.The first half of described brake wheel 7 places under the arc port.It can not only be prevented dust and attractive in appearance.
Described slide opening 51 can be divided into movable part 511 that is located at the first half and the elastic portion 512 that is located at lower part.The aperture of movable part 511 is bigger than the aperture of elastic portion 512.Described friction lining 8 is arranged on the movable part 511, and described spring 9 is arranged on the elastic portion 512.In order to prevent spring 9 landings, on elastic portion 512, be provided with an inserting column 513, insert in the inserting column 513 lower end of described spring 9.
Principle of the present utility model is: when shopping cart elevator castor promotes on the level land, under the effect of hand barrow self gravitation, ground-surface antagonistic force up pushes up brake wheel 7, and spring 9 shrinks, make brake wheel 7 and single-wheel 2 and ground maintain an equal level, hand barrow just can be walked on the ground like this.And it is when hand barrow is shifted the ordinary telegram ladder onto, because fluted on the ordinary telegram ladder.At this moment brake wheel 7 is not subjected to ground-surface antagonistic force, under the elastic force effect of spring 9, brake wheel 7 is turned down, make the bottom of brake wheel 7 snap on the ordinary telegram ladder fluted in, drive slide block 5 to lower slider, the front end of slide block snaps in single-wheel 2 teeth groove, and castor just can't rotate.Realize the braking effect of hand barrow.
