The specific embodiment
Come the technical solution of the utility model is further elaborated below in conjunction with accompanying drawing and specific embodiment.
Referring to a kind of brake device of handcart shown in Fig. 1-5, comprise the mainboard 1 that is fixedly connected for the main body with hand barrow, be fixedly installed on bracing frame on the mainboard 1, be arranged on rotationally the bar 3 of stopping on the bracing frame, be fixedly installed on trip(ping) lever 5, locking pedal 6 and release pedal 7 on the bar 3 of stopping, bracing frame comprises the supporting blade 2 that is positioned at mainboard 1 both sides and the main support 8 that is positioned at mainboard 1 middle part, the stop two ends of bar 3 removably are provided with the dish 4 of stopping, and can realize the brake of hand barrow so that the dish 4 of stopping is conflicted on trolley wheel.Locking pedal 6 is fixedly installed on the bar 3 of stopping, be provided with extension spring 9 between locking pedal 6 and the mainboard 1, release pedal 7 can be arranged on the main support 8 by rotating shaft 10 rotationally, wherein, the axial line of rotating shaft 10 parallels setting with the line of centers of the bar 3 of stopping, also being arranged with torsion spring 11 in the rotating shaft 10, conflicts respectively on release pedal 7 and main support 8 in the two ends of this torsion spring 11.The below of release pedal 7 is provided with locking piece 71 regularly, offer locked groove 72 on the locking piece 71, trip(ping) lever 5 is between release pedal 7 and locking piece 71, this brake gear has the stop state that closes and non-stopping and closes state, when being in, stops when closing state by brake gear, locking pedal 6 is operated, and at least part of trip(ping) lever 5 is fastened in the locked groove 72; When brake gear is in non-stopping when closing state, locking pedal 6 upwards resets, and described trip(ping) lever 5 is positioned at outside the locked groove 72.
In the present embodiment, the bar 3 of stopping is to be arranged in the following way on supporting blade 2 and the main support 8: all offer the first groove 22 that opens wide on the supporting blade 2 downwards, offer the second groove 81 that is open upwards on the main support 8, the bar 3 of stopping is plugged in the first groove 22 and the second groove 81, and the bar 3 of stopping can rotate along the line of centers of the bar 3 of stopping in the first groove 22 and the second groove 81.For so that supporting blade 2 can be welded on the desired location of mainboard 1 exactly, the two ends, the left and right sides of mainboard 1 offer respectively positioning groove, the top 21 of supporting blade can be inserted in the positioning groove on corresponding matching ground, after by positioning groove supporting blade 2 being positioned, just can exactly supporting blade 2 be welded on above-mentioned desired location.Like this, in the process of actual fabrication, mainboard 1 can be by the precision die moulding, the supporting blade 2 rear direct welding operations of packing in the positioning groove need not to carry out dimensional measurement again, have improved significantly work efficiency, moulding rear support sheet 2 is accurate with the size positions of mainboard 1, the bar 3 of stopping is concentric, and the coupling mechanism force of the dish 4 of stopping about when the brake of this brake gear is consistent, can solve effectively that body of handcart produces the problems such as car body rotary moving under slope pavement or other External Force Acting.Supporting blade 2 is two in the present embodiment, and these two supporting blades 2 are arranged on the left and right end portions of mainboard 1 symmetrically.
Referring to shown in Figure 4, the below of release pedal 7 also is provided with draw-in groove 73, this draw-in groove 73 is between release pedal 7 and trip(ping) lever 5, and draw-in groove 73 also is positioned on the locking piece 71, closes state lower time when brake gear is in non-stopping, trip(ping) lever 5 is positioned at outside the locked groove 72, because the elastic acting force of extension spring 9, locking pedal 6 upwards resets, and the bar 3 of stopping is in the supporting seat rotation and so that trip(ping) lever 5 rotates up around the line of centers of the bar 3 of stopping, when it goes upward to draw-in groove 73 places, have at least part trip(ping) lever 5 to be housed in the draw-in groove 73.In the present embodiment, trip(ping) lever 5 is the circular arc bar, draw-in groove 73 is arc groove, trip(ping) lever 5 is complementary with the size of draw-in groove 73, like this, the part that trip(ping) lever 5 is housed in draw-in groove 73 can match with draw-in groove 73, and trip(ping) lever 5 can effectively be fixed and can arbitrarily not rock, thereby effectively solved when using on the non-flat forms road surface, avoided trip(ping) lever 5 and the bar 3 of stopping in the hand barrow moving process, to produce clashing into and sent noise.In the present embodiment, locking piece 71 is integrated setting with release pedal 7, can reduce like this quantity of parts.
Below specify the specific works process of the present embodiment:
This brake gear is installed on the hand barrow main body, and the below of hand barrow main body generally is equipped with and drives the wheel that hand barrow moves, and this brake gear namely is installed in the bottom of hand barrow near the wheel place.
When hand barrow normally moved, the bar 3 of stopping was supported by supporting blade 2 and main support 8 and is arranged in the first groove 22 and the second groove 81, and the dish 4 of stopping maintains a certain distance with trolley wheel, and trip(ping) lever 5 is fixing by draw-in groove 73 simultaneously.When needs brake, the user steps on locking pedal 6, along with locking pedal 6 is descending, the bar 3 of stopping rotates, and trip(ping) lever 5 rotates thereupon and promotes simultaneously locking piece 71 and rotate, when trip(ping) lever 5 intersects with locked groove 72, part trip(ping) lever 5 namely slips in the locked groove 72 and is fastened in this locked groove 72, and when unclamping locking pedal 6, trip(ping) lever 5 can not skid off from locked groove 72 yet, thereby close under the state so that brake gear remains on to stop, the dish 4 of stopping this moment is adjacent on the wheel of hand barrow.When the needs hand barrow moves, step on release pedal 7, locking piece 7 rotates thereupon, dish 4 is conflicted on the wheel of hand barrow owing to stopping, stop bar 3 and trip(ping) lever 5 do not rotate at this moment thereupon, after locking piece 7 rotates certain angle, trip(ping) lever 5 just skids off from locked groove 72, after trip(ping) lever 5 skids off in the locked groove 72 under the application force of extension spring 9 pulling locking pedals 6 and up around the line of centers rotation of the bar 3 of stopping, when trip(ping) lever 5 goes upward to draw-in groove 73 place, trip(ping) lever 5 is realized resetting, and the dish 4 of stopping unclamps the subsides of trolley wheel are touched, and hand barrow is continued mobile.
This brake gear during fabrication, locking pedal 6, release pedal 7 can adopt material all in one piece, the moulding of precision die single-piece when manufacturing, saved welding process, have improved production efficiency, the size after the moulding is accurate, the succinct no-welding-spot of outward appearance.The structure of bar 3 of stopping simultaneously is simplified, is easy to moulding, after adopting brake device of handcart of the present utility model, the bar distance overhead of stopping in bar 3 distance overhead of stopping under the state that closes of the stopping brake gear compared to existing technology has increased significantly so that when brake brake gear the flatness on ground is required to reduce significantly.In this brake gear by adopting locking pedal 6 and release pedal 7 to switch the lock-out state of trip(ping) lever 5, thereby stopping of brake gear closed state and non-stopping closed state and switched so that the use state of brake gear is very clear.This brake process is simple to operate, and is easy to use.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
