The Novel brake castor that a kind of brake facing is adjustable, include top board, base plate, trundle bracket, brake pedal and brake shrapnel, wherein, the trundle bracket live splint is loaded between top board and the base plate, brake pedal cooperates with trundle bracket is hinged, brake shrapnel is installed in the trundle bracket by a bearing pin and its outer end contacts cooperation with the brake pedal contact, and the outer end of brake shrapnel is provided with the adjustable type brake facing, adjustable type brake facing and brake shrapnel activity threaded.When rolling wheel wear during large or roller diameter size change, by adjusting the adjustable type brake facing, can change the distance between brake facing and the roller edge, thereby guarantee that brake facing brake point maintains optimum distance with the roller edge, to keep preferably drag effect.
Further, also include the pedal that resets, the inner end of the described pedal that resets cooperates with brake pedal is hinged, and the middle part cooperates with the outer end of brake shrapnel is hinged.The utilization pedal that resets when needs are removed the castor braking mode, only need press down the pedal that resets, and can drive on the brake pedal and move, and moves synchronously thereby drive reset pedal and brake shrapnel, and then removes contacting of brake facing and roller edge.
Further, the described pedal that resets is superimposed on the brake pedal below, and both outer ends stretch out respectively.
Further, the below of described base plate is provided with the location chain wheel, and bottom week of location chain wheel is along being arranged at intervals with teeth, and the inner end of described brake shrapnel is provided with the opening with the teeth clutch phase interlock of locating chain wheel.Utilize brake shrapnel opening and the phase interlock of locating the chain wheel teeth, can be with trundle bracket and utensil locking.
Further, described top board, base plate and location chain wheel are by a rivet captive joint.
Further, described trundle bracket includes wheel carrier and carriage, and wherein, wheel carrier is loaded between top board and the base plate by the rivet live splint, and wheel carrier is provided with ball with the position that top board contacts with base plate, and carriage is inlayed to be fixed on the wheel carrier by wedge and formed one with wheel carrier.
Further, the middle part of described brake shrapnel raises up and forms a groove position, and the groove position is arranged on the bearing pin in the carriage, and brake shrapnel also is provided with a upwardly extending branch tablet, and branch tablet contacts cooperation with contact of the interior end of carriage.
The utility model compared with prior art, its beneficial effect is:
By adjusting the adjustable type brake facing, when rolling wheel wear during large or roller diameter size change, can change the distance between brake facing and the roller edge, thereby guarantee that brake facing brake point maintains optimum distance with the roller edge, keeping preferably drag effect, and integral structure is simply compact, easy to manufacture, easy to operate, practical safe and reliable.
In order to understand more clearly the utility model, set forth the specific embodiment of the present utility model below with reference to description of drawings.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the Novel brake castor that brake facing described in the utility model is adjustable has been drawn together top board 1, base plate 2, trundle bracket 3, brake pedal 4, pedal 5 and brake shrapnel 6 reset.
Above-mentioned trundle bracket 3 includes wheel carrier 31 and carriage 32, wherein, wheel carrier 31 upper ends are loaded between top board 1 and the base plate 2 by rivet 7 live splints, and wheel carrier 31 is provided with ball with top board 1 with the position that base plate 2 contacts, and carriage 32 is inlayed to be fixed on the wheel carrier 31 by wedge and formed one with wheel carrier 31.
The inner end of above-mentioned brake pedal 4 and 32 hinged cooperations of the carriage of trundle bracket, the pedal 5 that resets is superimposed on brake pedal 4 belows, its inner end and 4 hinged cooperations of brake pedal, the middle part cooperates with the outer end of brake shrapnel 6 is hinged, and the outer end of brake pedal 4 and the pedal 5 that resets stretches out respectively, so that jam on.
The middle part of above-mentioned brake shrapnel 6 raises up and forms a groove position, the groove position is arranged on the bearing pin 321 in the carriage 32, and the outer end of brake shrapnel 6 is provided with adjustable type brake facing 8, adjustable type brake facing 8 and brake shrapnel 6 activity threaded, and brake shrapnel 6 also is provided with a upwardly extending branch tablet 61, and branch tablet 61 contacts cooperation with the 32 interior end of carriage contact.
The below of above-mentioned base plate 2 also is provided with location chain wheel 9, and bottom week of location chain wheel 9 is along being arranged at intervals with teeth 91, and the inner end of described brake shrapnel 6 is provided with the opening with the teeth 91 clutch phase interlocks of locating chain wheel 9.Utilize brake shrapnel opening and the phase interlock of locating the chain wheel teeth, can be with trundle bracket and utensil locking.Further, described top board 1, base plate 2 and location chain wheel 9 are by above-mentioned rivet 7 captive joints.
Operating principle of the present utility model is as described below:
When needing braking, jam on brake pedal, driving the brake shrapnel outer end by the pedal that resets is bent downwardly, adjustable type brake facing on the brake shrapnel is close to the roller edge, utilizes the friction force brake wheel between adjustable type brake facing and the roller edge to rotate, simultaneously, the inner end of brake shrapnel moves up, the opening of this end and the teeth phase interlock of locating chain wheel, thus pin trundle bracket, guarantee trundle bracket and roller genlocing;
When wanting brake off, jam on equally the pedal that resets, the inner end of the pedal that resets is upturned, and passes through interlink function, the drive brake pedal moves up, brake pedal drives again the outer end of reset pedal and brake shrapnel and moves synchronously, thereby removes contacting of brake facing and roller edge, simultaneously, along with moving on the brake shrapnel outer end, the inner end of brake shrapnel moves down, thereby the opening of this end breaks away from the teeth of location chain wheel, and trundle bracket is free to rotate.
