Utility model content
The purpose of this utility model is the draw-bar box proposing a kind of strap brake function, avoids quick downslide, thus draw-bar box is easily manipulated when it adopts brake gear that draw-bar box is glided on abrupt slope.
For reaching this object, the utility model by the following technical solutions:
A kind of draw-bar box of strap brake function, comprise casing, the top of casing is provided with pull bar, the bottom of casing is provided with roller, wherein, the back of described casing is provided with brake gear, and described brake gear comprises expansion link, described expansion link can move up and down, and the end of described expansion link is provided with telescopic pin.
Wherein, described telescopic pin comprises pin rod and key seat, and the top of described pin rod is provided with elastic device, and when described elastic device is in free state, the end of described pin rod stretches out described key seat and stretches out described tank floor.
Preferably, described elastic device is spring.
Wherein, the end of described pin rod is provided with buffer unit.
Preferably, described buffer unit is Rubber end.
Preferably, described Rubber end is abrasive rubber head.
Wherein, described expansion link arranged outside has sleeve pipe, and described sleeve pipe is fixed on described box back surface, and described expansion link is set in described sleeve pipe, and the end of described sleeve pipe is provided with stopping means.
Wherein, described expansion link top is provided with the handle being convenient to pull described expansion link upper and lower, and described handle is arranged at described casing top.
The draw-bar box of a kind of strap brake function described in the utility model, the bottom of casing is provided with brake gear, brake gear comprises expansion link, expansion link can move up and down, the end of expansion link is provided with telescopic pin, and draw-bar box is when abrupt slope glides, and expansion link pushes away downwards and makes the telescopic pin of its end stretch out the bottom surface of described casing and offset with domatic, produce the resistance preventing draw-bar box from gliding fast, make draw-bar box in downslide process, avoid excessive velocities to be difficult to manipulation.

Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1, Figure 2, a kind of draw-bar box of strap brake function described in the present embodiment, comprise casing 1, the top of casing 1 is provided with pull bar 2, and the bottom of casing 1 is provided with roller 3, wherein, the back of described casing 1 is provided with brake gear 4, described brake gear 4 comprises expansion link 43, and described expansion link 43 can move up and down, and the end of described expansion link 43 is provided with telescopic pin 44.
Described telescopic pin 44 comprises pin rod 443 and key seat 441, the top of described pin rod 443 is provided with spring 442, described pin rod 443 is fixed in described key seat 441 by the described spring 442 on top, when described spring 442 is in free state, the end of described pin rod 443 stretches out described key seat 441 and stretches out described casing 1 bottom surface; The end of described pin rod 443 has been provided with the wear-resisting Rubber end 444 of cushioning effect; The pin rod 443 postponing its end when described expansion link 43 downwards stretches out the bottom surface of described casing 1 and offsets with domatic, because the top of described pin rod 443 is provided with spring 442, described pin rod 443 is subject to domatic reaction force makes spring 442 compress, therefore described pin rod 443 can from main regulation, avoids draw-bar box expansion link 43 described in abrupt slope downslide process and causes Ka Dun and dumb with domatic offseting; Described 444 Rubber ends play buffering and anti abrasive effect.
Described expansion link 43 arranged outside has sleeve pipe 42, and described sleeve pipe 42 is fixed on described casing 1 back side, and described expansion link 43 is set in described sleeve pipe 42, and the end of described sleeve pipe 42 is provided with stopping means 421; Described expansion link 43 top is provided with the handle 41 being convenient to pull described expansion link about 43, and described handle 41 is arranged at described casing 1 top; By described sleeve pipe 42, described brake gear 4 is fixed on described casing 1 back side, described stopping means 421 and handle 441 for controlling the upper-lower position of described expansion link 43, thus play the effect of open and close brake gear 4.
The case and bag of the strap brake function described in the present embodiment have the following advantages: 1, add brake gear, make draw-bar box avoid excessive velocities to cause in downslide process and be difficult to control, and the domatic pin rod contacted is provided with self-regulation spring and abrasive rubber head, avoid Ka Dun and wearing and tearing in the process that draw-bar box is glided on abrupt slope; 2, the box shape of draw-bar box does not need to change, and brake gear is fixed on box back surface, does not affect the profile of draw-bar box; 3, take less the long-pending of casing, brake device structure is simple, volume is little, is jointly arranged at the body back side with the pull bar of draw-bar box, increases brake gear very little to taking of tank-volumes.
