Description

Rake claw position structure of straw rake

The utility model relates to the harrow structure of garden tool set, is meant the rake pawl location structure of harrow especially.

From prior art as can be known, harrow is to be used to harrow the leaf or the withered grass of getting the ground for horticulture person, in order to adapt to the convenience that different rakes is got thing and collected, its rake pawl generally all is designed to have flexible function, as shown in Figure 1, schematic appearance for a kind of habitual harrow 80, this harrow 80 is by a holding rod 81 substantially, one rake claw 82 and certain hyte part 84 3 are partly formed, wherein these holding rod 81 front ends set firmly to link a spacer 83, just the rake pawl for this rake claw 82 wears combination, this positioning component 84 then is to be provided with a press fixing piece 86 and in a U-shaped bearing 85 to press bar 87, this presses bar 87 is to press this press fixing piece 86 and this bearing 85 is combined with holding rod 81, and linking in the front end of this bearing 85 has a grip block 88 again, 88 of this grip blocks are connected with mutually with this rake claw 82 again, by this bearing 85 can along this holding rod 81 axially appropriateness adjust the location, impelled this rake claw 82 to have flexible function and can conveniently harrow and get and collect.But, when each member manufacturing of the coupling unit 84 of habitual harrow 80 is assembled, all be by metal sheet dash be set as shape after, electroplated earlier, and then in addition the pressing riveted joint is formed, and its procedure is loaded down with trivial details, it is time-consuming to assemble, the Master Cost height of each member, and make the price of harrow 80 higher, can't popularize.

Main purpose of the present utility model is to provide a kind of rake pawl location structure of harrow, and it is simple in structure, assembling is easy, can significantly reduce the manufacturing cost of harrow.

An of the present utility model purpose then is to provide a kind of rake pawl location structure of harrow, and it has profile attractive in appearance.

The rake pawl location structure of a kind of harrow provided by the utility model, it is made up of a rake claw and a holding rod substantially, it is characterized in that: this holding rod appropriate position is provided with a positioning seat, this positioning seat is a plastics one ejection formation, it includes a pivot cover portion, this pivot cover portion has a pivot trepanning and just is set in the outer peripheral edges of this holding rod, and extend respectively in the side of this pivot cover portion and to be provided with a blocking part and a joint portion, wherein this blocking part is along the clamping groove that is axially arranged with of this holding rod, and this joint portion then is connected with this rake claw; One pressure handle also is a plastics one ejection formation, is the clamping groove that is hubbed at this blocking part with a pivot, and it has the shank that a packing head end and that is eccentric shape is elongated rod shape; Follow the pivot turn of this pressure handle by this shank, impel the maximum eccentric periphery of this packing head end to urge the outer peripheral edges of this holding rod, combine and this positioning seat is set firmly mutually with holding rod.

Relevant the utility model detailed construction, function and characteristics can and be able to abundant understanding by the detailed description of following examples conjunction with figs., wherein:

Fig. 1 is a kind of schematic appearance of habitual harrow.

Fig. 2 is the stereoscopic schematic diagram of the utility model one preferred embodiment.

Fig. 3 is that schematic perspective view is amplified in the part of positioning seat of the present utility model, and shows the packing bonding state of pressure handle and holding rod.

Fig. 4 is the schematic diagram identical with Fig. 3, and shows the released state of pressure handle and holding rod.

See also Fig. 2 to 4, harrow rake pawl location structure of the present utility model is made up of a holding rod 10, a rake claw 20 and certain hyte part 30 3 parts substantially, wherein:

This holding rod 10 is the round bar of a strip, and the one end is provided with a shank part 11, and the other end then vertically has been horizontally set with a spacer 12, then provides the circular hole 13 of predetermined number on this spacer 12.

This rake claw 20 generally is made up of the rake pawl 21 of predetermined number, and each harrows the circular hole 13 that pawl 21 just can pass this spacer 12, and its front end respectively forms the bending of predetermined angular.

30 of this positioning components are made up of a positioning seat 31 and a pressure handle 32, wherein this positioning seat 31 is a plastics one ejection formation, it includes a pivot cover portion 33, the axle center of this pivot cover portion 33 has provided a trepanning 34, this trepanning 34 just can be set in the outer peripheral edges of this holding rod 10, and up extend in the front end of this pivot cover portion 33 and to be provided with a blocking part 35, this blocking part 35 axially then is concaved with a clamping groove 36 along this holding rod 10, and extend again in the opposite end of this blocking part 35 and to be provided with a joint portion 37, the bottom of this joint portion 37 axially then up is concaved with a storage tank 38 perpendicular to this holding rod 10, just the rake pawl 21 for this rake claw 20 is installed with, and is able to a board 39 cooperations two riveted

joint elements

41,42 and make the rake pawl 21 of this rake claw 20 can't break away from this storage tank 38; And this pressure handle 32 also is a plastics one ejection formation, it has a clamping head end 321 and a shank 322, this packing head end 321 is cooperated a pivot 43 and the fore-telling that is hubbed at this blocking part 35 is pulled in the groove 36, can the suitable angle swing of this pivot 43 for the axle center produces, this packing head end 321 has outer peripheral edges that are eccentric shape, the all intermarginal pre-positions of its maximum eccentric are provided with one and outwards are the separately circular arc grooving 323 of shape, impel 323 clamping parts 324 that form a curved arc shape of its packing head 321 and grooving, the eccentric external diameter of this clamping part 324 is slightly larger than the distance between these pivot 43 axle center and this holding rod 10 outer peripheral edges.

See also shown in Figure 2ly again, the positioning seat 31 of the utility model positioning component 30 is the outer peripheral edges of compeling to support this holding rod 10 by the clamping part 324 maximum eccentric peripheries of the packing head end 321 of this pressure handle 32, combines and impel 10 of this positioning seat 31 and holding rods to interfix; And when this positioning seat 31 must be along the moving axially of this holding rod 10, be earlier that this pressure handle 32 is moving toward upper plate, as shown in Figure 3, impel the clamping part 324 of its packing head end 321 to leave the outer peripheral edges of this holding rod 10, even also the fastening force on these holding rod 10 surfaces disappears, this positioning seat 31 can move axially to the appropriate location along this holding rod 10 soon, and then action established in the accent that this pressure handle 32 pressing again can be finished this positioning seat 31, quite easy fast.In brief, axially move forward and backward fixing by this positioning seat 31 along this holding rod 10, as if can make the rake pawl 21 of this rake claw 20 present strutting and actuating like umbrella, and applicable to various user mode and collection, it then is known using situation and effect as for it, does not repeat in this appearance.

Again, the grooving 323 that the pressure handle 32 packing head ends 321 of rake pawl location structure of the present utility model are had can provide the clamping part 324 1 of this packing head end 321 preferable elastic compression or dilating effect, so that this pressure handle 32 sets firmly do swing or when loosening, it is more smooth and easy and action is more certain that it makes kinetic energy.

To sum up state old, each element of the rake pawl location structure of the utility model harrow, not only simple in structure and to make assembling more easy, can significantly reduce manufacturing cost.
