Affiliated technical field
The utility model relates to a kind of mower, especially the height adjustment mechanism in the mower.
Background technology
Usually, the cutting tool that mower comprises base, be installed in motor or the internal combustion engine on the base and be installed in the base below, thus this cutting tool is driven by motor or internal combustion engine and is carried out high speed rotating so that the weeds on the lawn are cut.Mower also be provided with several can be installed in roller on the described base and a kind of height adjustment mechanism with regulate cutting tool with respect to several rollers (being ground) thus height guarantee weeds are cut to proper height.Be provided with a regulating handle and positioning piece in the above-mentioned height adjustment mechanism, usually this regulating handle need separate from keeper when highly regulating, after highly adjusting is finished, be positioned in the keeper once more, thereby make mower keep the height that has regulated.Finishing highly at regulating handle needs a resetting structure that it can be navigated in the keeper automatically after regulating.In the prior art, disclose as European patent WO9809499 usually, regulating handle is designed to plastics or the metallic spring part, thereby the elastic recovery that relies on itself is in keeper.Therefore operation is relatively required great effort when regulating height, and has the possibility of elastic component fracture failure.
Summary of the invention
In order to overcome existing mower height adjustment mechanism deficiency, the utility model provides a kind of novel height adjustment mechanism, and it is simple in structure, good operability.
The technical scheme that its technical problem that solves the utility model adopts is: described mower comprises base, and be installed in height adjustment mechanism on the described base, described height adjustment mechanism comprises that connecting rod, the described handle resetting structure of regulating handle are arranged between described regulating handle 9 and the described connecting rod, it is characterized in that: described handle resetting structure comprises connector, latch and the elastic reset spare that is fixed in the U-shaped on the described connecting rod, and described regulating handle links to each other with latch by described connector with described connecting rod.Described connector is provided with two bridge joint holes, and described latch is rotatable to be contained in the described bridge joint hole.Described regulating handle lower end is provided with a connecting hole, and is connected with described connecting rod gudgeon by described connecting hole.Described elastic reset spare is a torsion spring, and described torsion spring set is located on the described latch, and acts on described connecting rod and described regulating handle respectively.
The beneficial effects of the utility model are, by at the connecting hole of regulating handle lower end, be fixed in connector on the connecting rod and the cooperation between the latch, make the operator when using regulating handle to regulate to mow height easy to operate easily.

Among the figure: 1. base 2. road wheels 3. arm-rest frames 4. covers 6. front axles 7. hind axles 8. connecting rods 9. regulating handles 10. keepers 11 connectors 12. latches 13. elastic reset spares 14. thin bar 15. handles 16. connecting holes 17. bridge joint holes 18. gear grooves, 19. main parts, 20. abutment end, 21. elongated ends
Embodiment
With reference to figure 1, be depicted as stereogram corresponding and the utility model embodiment mower.This mower comprises base 1, road wheel 2, arm-rest frame 3 and cover 4.Base is provided with drive motors (figure does not show), transmission mechanism (figure does not show), and the cutting tool (figure does not show) that is installed in bottom the base cuts, clears up the weeds on the lawn.Arm-rest frame 3 is used for carrying out both hands in the process of mower work and grips.Arrangement for adjusting height (figure does not show) also is installed on the base 1, and arrangement for adjusting height comprises front axle 6, hind axle 7, connecting rod 8, regulating handle 9, keeper 10.Be positioned diverse location in the keeper 10 by regulating handle 9 and regulate front axle 6 and hind axle 7 height, thereby realize the change of mower base 1 and road wheel 2 relative altitudes, reach the purpose that changes the height of mowing with respect to base 1.
Referring to figs. 2 to Fig. 4, the handle resetting structure is arranged between regulating handle 9 and the connecting rod 8, and comprises the connector 11 that is arranged on the connecting rod 8, and latch 12 and elastic reset spare 13.Regulating handle 9 is made up of a thin bar 14 and handle 15, is provided with a connecting hole 16 in thin bar 14 lower ends.Connector 11 is roughly U-shaped, is fixed in connecting rod 8 central authorities, which is provided with a pair of bridge joint hole 17; Above-mentioned thin bar 14 can be contained in the U-lag of connector 11, and is connected with connector 11 by the rotation cooperation in latch 12, connecting hole 16 and bridge joint hole 17.Be distributed with a plurality of gear grooves 18 in the keeper 10, regulating handle 9 can be positioned any one in above-mentioned a plurality of gear groove 18.Described elastic reset spare 13 is generally torsion spring, and this torsion spring includes two main parts 19, and these two main parts 19 link to each other by an abutment end 20, and all are provided with an elongated end 21 on each main part 19.Two main parts 19 of torsion spring are set in the two ends of latch 12 respectively, abutment end 20 is resisted against the lower end of regulating handle 9, two elongated end 21 hooks are located on the connecting rod 8, therefore torsion spring acts on regulating handle 9 and connecting rod 8 respectively, owing to have a torsion between the abutment end 20 of torsion spring and the elongated end 21, and regulating handle 9 and connecting rod 8 are pivotally connected, therefore regulating handle 9 and connecting rod 8 between have a power that makes it can be maintained fixed the position, can realize automatically reseting of regulating handle 9 after having regulated the mowing height, promptly regulating handle can be automatically positioned in a plurality of gear grooves 18 of keeper 10.
With reference to figure 5 and Fig. 6, corresponding to the reseting procedure of regulating handle.When the operator regulates the mowing height, at first regulating handle 9 being applied an external force makes it break away from gear groove 18 in keeper 10, change the position of regulating handle 9 then on respect to the fore-and-aft direction of base 1, when being adjusted to desirable height, with reference to figure 5, the operator decontrols regulating handle 9, and this moment, regulating handle 9 can navigate in the gear groove 18 of keeper 10 under the effect of elastic reset spare 13 automatically.
Therefore operator's operation when using regulating handle 9 to regulate the mowing height is more convenient and light.
The utility model is not limited only to above cited embodiment.
