The specific embodiment
Be described further below in conjunction with the switching device of drawings and the specific embodiments the utility model hand barrow handle.
Shown in accompanying drawing 1～4, the handle 2 of hand barrow is in the lock state by switching device 4 in the present embodiment, and when switching device 4 was not opened, handle 2 can not fold.
This hand barrow mainly comprises as the lower part: supporting part 1, be arranged on supporting part 1 below caster wheel 3, be arranged on both sides, supporting part 1 rear end handle 2, be arranged on the switching device 4 of supporting part 1 rear end midway location.Switching device 4 comprises that matching, limit handle 2 with the bottom of handle 2 rotates or remove the sliding pin 41 that handle 2 is limited, the both sides at supporting part 1 rear portion are respectively equipped with sliding pin bearing 42, sliding pin bearing 42 is corresponding with the position of handle 2, and sliding pin bearing 42 is fixed on the supporting part 1; Sliding pin bearing 42 has symmetrical supporting walls 42a, 42b, cooresponding handle 2 between two supporting walls 42a, 42b, and by bearing pin be hinged on supporting walls 42a, 42b the top 42c place, hole.Last chute 42d, the 42e that limits sliding pin 41 sliding traces that be arranged with of supporting walls 42a, the 42b of two sliding pin bearings 42, sliding pin 41 is plugged in chute 42d, the 42e; Be hinged with pedal 43 on the supporting part 1, and the free end of pedal 43 is positioned at the top of sliding pin 41.Concrete structure is: pedal 43 is half moon, and supporting part 1 is provided with the half moon breach suitable with pedal 43; The front end of pedal 43 is provided with hinged seat 43a, and supporting part 1 is provided with two erecting beds 44, is equipped with transverse axis 45 on the erecting bed, and the hinged seat 43a of pedal 43 is located on the transverse axis 45, can rotate around transverse axis 45.
In addition, be arranged with retracing spring 46 on the sliding pin 41, retracing spring 46 is 2, divides to be located at close sliding pin bearing 42 places on the sliding pin 41, and the other end of retracing spring 46 is fixed on the supporting part 1.
As shown in Figure 1, the upper surface of supporting part 1 and castor 3 cooresponding positions are provided with groove 11, and these grooves 11 are used to locate another hand barrow caster wheel.When many hand barrows stacked mutually, this groove 11 can position the hand barrow caster wheel on upper strata, deposited thereby guarantee hand barrow failure-free superposes, and avoided mutual slip.
Therefore, under the state that handle 2 is opened fully (when promptly using state), sliding pin 41 overheads are (as accompanying drawing 5) on the rear wall of handle 2 bottoms, rotates forward thereby limit handle.And the main baffle plate 5 by handle 2 bottom front trucks that rotates backward of handle 1 limits.This baffle plate 5 is L shaped, and its Transverse plane directly is fixed on the supporting part 1 by screw and nut.
When needs fold handle 2, the outer end of pedal 43 tramps with one's feet, shown in accompanying drawing 5～7, pedal 43 drives sliding pin 41 is moved to chute 42d, 42e by the epimere of chute 42d, 42e hypomere, thereby remove qualification to handle 2 rear walls, make and successfully cross sliding pin 41, fold in loading plate 1 plane receiving 2 lower ends.And sliding pin 41 is not owing to there be stopping of handle 2, and when the external force on the pedal 41 was removed, sliding pin 41 slide into epimere by the hypomere of chute 42d, 42e, thereby also driving pedal 43 automatically reset, shown in accompanying drawing 8,9 under the effect of retracing spring 46.
Open once more when receiving 2 when needs, directly swing handle 2 will push sliding pin 41 to the lower end of receipts 2, as shown in Figure 10.The epimere of sliding pin 41 from chute 42d, 42e promoted to hypomere, and when shifting lowest order onto, the lower end of handle 2 is around arriving sliding pin 41 tops, and at this moment, the mated condition of handle 2 and sliding pin 41 as shown in Figure 6.When handle 2 continues to open, handle 2 has been walked around sliding pin 41, this moment, sliding pin 41 slided into epimere by the hypomere of chute 42d, 42e under the effect of retracing spring 46, overhead is on the rear wall of handle 2 lower ends, as shown in Figure 3, rotate forward thereby define handle 2, pedal 43 also automatically resets under the combined action of retracing spring 46 and sliding pin 41 simultaneously.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; therefore, all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the utility model claim.
