Further, brake block and rolling wheel support are integral type structure.
Further, rotary handle includes sleeve and handle, and the outer surface of handle and the second end contact is arcuation smooth surface, and during confined state, sleeve set is through on roller pin, and handle at least one end lowest part domatic with described in the second end face contacts.
Further, second end face includes the first plane and the second plane, first plane and the second plane are along brake block the second end face alternate setting of circumferencial direction, first plane is higher than the second plane, between first plane and the second plane, groove is set, groove bottom land is less than the second plane, arranges light landslide surface as transition face between groove bottom land and the second plane.
Further, the second end face includes two to the first plane and described second plane.
Further, handle two ends lay respectively at the both sides of sleeve.
Further, left socle and right support are elastic material.
Compared with prior art, the beneficial effects of the utility model are: roller can running status time, rotary handle is placed in the lowest part that brake block the second end face is domatic, connected by the pin of roller pin, the left socle of rolling wheel support, certain gap is had between right support and wheel body, when needs brake, move rotary handle, make rotary handle slide into along the second end face domatic from domatic lowest part domatic to exceed, and then under the opposition of roller pin end cap and pad, squeeze and push away brake block and then squeeze that to push away rolling wheel support close to wheel body, rotation along with rotary handle, gap between rolling wheel support and wheel body is the least, until rolling wheel support clamping wheel body makes wheel body not rotate, i.e. wheel body is in braking state.Above-mentioned brake structure is simple, easy to use, provides convenient for carrying the trip of draw-bar box.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is further described.Following example are only used for clearly illustrating the technical solution of the utility model, and can not limit protection domain of the present utility model with this.
A kind of draw-bar box idler wheel of strap brake, including wheel body 1, rolling wheel support 2 and roller pin 3, rolling wheel support 2 includes left socle 201 and right support 202, roller pin 1 sequentially passes through left socle 201, wheel body 1 and right support 202, rolling wheel support 2 cylinder lever connecting rod case body, including brake part, brake part includes rotary handle 4, pad 5 and brake block 6, and brake block 6 and rolling wheel support 2 are integral type structure.Brake block 6 includes the first end face 61 and the second end face 62, during confined state, roller pin 3 sequentially passes through pad 5, rotary handle 4 and brake block 6, first end face 61 abuts with rolling wheel support 2 outer surface, second end face 62 abuts with rotary handle 4, rotary handle 4 includes that sleeve 41 and handle 42, handle 42 two ends lay respectively at the both sides of sleeve 41, and the outer surface that handle 42 contacts with the second end face 62 is arcuation smooth surface.During confined state, sleeve 41 set is through on roller pin 3；Second end face 62 includes the first plane 621 and the second plane 622, two pairs of the first planes 621 and the second plane 622 are along the brake block 6 second end face 62 alternate setting of circumferencial direction, the two ends of corresponding assembling handle 42, first plane 621 is higher than the second plane 622, between first plane 621 and the second plane 622, groove 623 is set, groove 623 bottom land is less than the second plane 622, the difference in height of groove 623 bottom land and the second plane 622, more than the gap between rolling wheel support 2 and wheel body 1, arranges light landslide surface as transition face 624 between groove 623 bottom land and the second plane 622.When wheel body can roll, the arcuation smooth surface at handle 42 two ends contacts with the cooperation of groove 623 bottom land.When needing brake, move rotary handle 4, rotary handle 4 is made to slide into the second plane 622 along transition face 624 from groove 623 bottom land, owing to left socle 201 and right support 202 are elastic material, and then under the opposition of roller pin 3 end cap and pad 5, squeeze and push away brake block 6 and then squeeze and push away the rolling wheel support 2 of elastic material and clamp to wheel body 1, rotation along with rotary handle 4, gap between rolling wheel support 2 and wheel body 1 is the least, until rolling wheel support 2 clamps wheel body 1 and makes wheel body 1 not rotate, i.e. draw-bar box idler wheel is in braking state.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
