The utility model content
The technical problems to be solved in the utility model is the above-mentioned difference at prior art, and a kind of simple in structure, easy to use, brake type universal caster wheel that roller can be braked is provided.
The technical solution of the utility model is such: a kind of brake type universal caster wheel, comprise wheel seat, be provided with rotating shaft at the wheel seat middle part, on the rotating shaft both sides roller is housed, wherein, described roller medial surface is provided with a circle limiting tooth, is hinged with brake rod in the wheel seat side, the both sides of brake rod are provided with respectively and the cooresponding brake tooth piece of both sides roller medial surface limiting tooth, and the rolling brake bar can make the brake tooth piece with the limiting tooth engagement or separate.
In above-mentioned a kind of brake type universal caster wheel, lower end, described wheel seat side is provided with a portion of colluding, and the corresponding position of brake rod is provided with the groove that colludes that adapts, between wheel seat and the brake rod by collude groove snap onto collude in the portion hinged.
In above-mentioned a kind of brake type universal caster wheel, described brake rod is a U-shaped, on the wheel seat relative, be provided with positioning convex strip with colluding a portion, be provided with spacing draw-in groove with the corresponding brake rod of positioning convex strip side, be provided with to outer lug at spacing draw-in groove upper side, when positioning convex strip is positioned at spacing draw-in groove, brake tooth piece and limiting tooth engagement.
In above-mentioned a kind of brake type universal caster wheel, described wheel seat is provided with guide groove, is provided with the cylinder that slides along this guide groove between the brake tooth piece on brake rod both sides.
After the utility model adopted said structure, the brake tooth piece by the brake rod both sides cooperated with limiting tooth, the mode of utilizing the rotation brake bar easily the item roller braking and brake releasing, have simple in structure, easy to operate advantage.
Description of drawings
Below in conjunction with the embodiment in the accompanying drawing the utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation of brake rod in the utility model;
Fig. 4 is the birds-eye view of Fig. 3;
Fig. 5 is the view of glancing impact.
Among the figure: wheel seat 1, collude a 1a of portion, positioning convex strip 1b, guide groove 1c, rotating shaft 2, roller 3, limiting tooth 3a, brake rod 4, brake tooth piece 4a, collude groove 4b, spacing draw-in groove 4b, protruding 4c, cylinder 4d.
The specific embodiment
Consult Fig. 1 to shown in Figure 4, a kind of brake type universal caster wheel of the present utility model, comprise plastics wheel seat 1, be provided with rotating shaft 2 at wheel seat 1 middle part, on rotating shaft 2 both sides plastic roller 3 is housed, be provided with a circle limiting tooth 3a at roller 3 medial surfaces, be hinged with plastics brake rod 4 at wheel seat 1 right flank, in the present embodiment, the pivotally attached method is to be provided with in lower end, wheel seat 1 side to collude a 1a of portion, the corresponding position of brake rod 4 be provided with adapt collude groove 4b, between wheel seat 1 and the brake rod 4 by collude groove 4b snap onto collude in the 1a of portion hinged; Brake rod 4 in the present embodiment is a U-shaped, be provided with in the both sides of brake rod 4 respectively and the cooresponding brake tooth piece of both sides roller 3 medial surface limiting tooth 3a 4a, with collude a wheel seat that the 1a of portion is relative 1 on be provided with positioning convex strip 1b, being provided with spacing draw-in groove 4b, be provided with to outer lug 4c at spacing draw-in groove 4b upper side with the corresponding brake rod of positioning convex strip 1b 4 sides; Be provided with guide groove 1c at wheel seat 1, be provided with the cylinder 4d that slides along this guide groove 1c between the brake tooth piece 4a on brake rod 4 both sides, cylinder 4d plays stable effect of moving, and can prevent effectively that brake tooth piece 4a from departing from.
When the utility model specifically used, the state when its roller 2 is braked was consulted shown in Figure 1, when at this moment positioning convex strip 1b is positioned at spacing draw-in groove 4b, and brake tooth piece 4a and limiting tooth 3a engagement, roller 2 can not rotate; Rotate brake rod 4, the groove 4b that colludes of brake rod 4 sides will be around colluding the 1a of a portion rotation, owing to the elastic deformation of plastics make spacing draw-in groove 4b break away from positioning convex strip 1b the position and downwards the right side move, simultaneously, brake tooth piece 4a also separates with limiting tooth 3a, at this moment shape body is consulted shown in Fig. 5, and roller 2 recovers rotary state, and braking is removed.
