Abstract

The invention provides a rope clamping device of a grass trimmer. Grass trimmer rope clamping pieces (4 and 6) are arranged on a grass trimmer main body (1); grass trimmer guiding and fixing pieces (2 and 5) correspond to the grass trimmer rope clamping pieces (4 and 6); and the purpose that grass trimming ropes (7 and 15) are positioned, fixed and replaced quickly and conveniently is achieved through the horizontal fixed clamping force of secondary cavity inner springs (14 and 22) on secondary key clamping bodies rope holes (10 and 18) and the self-locking function of a grass trimming rope replacement hole (24) to the secondary key clamping bodies rope holes (10 and 18). The flexibility and the bendability of a grass trimming rope in a grass trimmer storer are eliminated, the grass trimming rope is guaranteed to be fixed and positioned in a linear shape on the grass trimmer rope clamping device; the dependency of the grass trimmer rope on the power transmission centrifugal force is reduced, the working efficiency is improved, and the mechanical operation and the energy consumption saving are well achieved.

Description

A kind of mower card rope device

Technical field

The present invention relates to the garden instrument technical field, particularly a kind of mower card rope device.

Background technology

Existing mower storage rope device all is to twine the rope product of beating the grass that stores based on plastic materials such as nylon in the head of beating the grass is beaten the grass device, to discharge the operation of length as required when working.

Existing mower generally is divided into two big classes: electric-powered mower, the diameter 1.3---1.6 millimeter of the rope of beating the grass of joining; Fuel engines power mower, the diameter 2.4---3.5 millimeter of the rope of beating the grass of joining.

Because: electric-powered mower, the rope of the diameter 1.3---1.6 millimeter of joining will being beaten the grass, the rope of beating the grass that rotates tiny diameter by the high speed of electromotor gets rid of straight, pass to the centrifugal force that tiny diameter is beaten the grass and restricted with electromotor, the effect of beating the grass, such operation principle---can learn the significant wastage of electric power intuitively.

Because: fuel engines power mower, the rope of the diameter 2.4---3.5 millimeter of joining being beaten the grass is stored in the device of beating the grass on the head of beating the grass by the mode of twining, when work, discharge the operation of length as required after, the bending of restricting all of beating the grass.High speed rotation by the fuel engines rope of beating the grass of bending is got rid of directly, passes to the centrifugal force that gets rid of the rope of beating the grass after straight with engine, the effect of beating the grass, and such operation principle---can learn the significant wastage of engine power intuitively.

When reality is used operation, obviously exposed the disadvantage that the existing rope holder of beating the grass of configuration produces on the head of beating the grass, change the existing rope holder of beating the grass of configuration on the head of beating the grass, the demand of essence is arranged.

Along with the development in pluralism of society, urban environment is all optimized constantly with greening, to the equipment of garden instrument and energy-conservation on, high-tech requirement renewal, that have more advantage has all been proposed.

Summary of the invention

The present invention realizes mechanically actuated better and energy efficient to implement providing a kind of mower card rope device.

In order to achieve the above object, the embodiment of the invention provides a kind of mower card rope device, it is characterized in that product is with the vertical bar shape of fixing, the mode adapted typing of location, the solid shape rope of beating the grass, abandon softness and the bendability of mower rope in the existing rope holder of beating the grass, fixing, the location vertical bar shape that guarantee to beat the grass on the mower card rope device and restrict.

Compare with the existing rope holder technology of beating the grass, the embodiment of the invention has following advantage and is:

1, beat the grass rope change convenient; Fixing, location guarantees.

2, reduce power is transmitted the dependence of centrifugal force.

3, reduce the diameter that mower is joined the rope of beating the grass.

4, increase operating efficiency.

5, energy savings.

Embodiment

Introduce a kind of mower card of embodiment of the invention rope device in detail below in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4.

Mower main body (1) at a kind of mower card rope device has mower card rope spare (4) (6), the rope guide shaft fixing unit (2) (5) and the corresponding existence of mower card rope spare (4) (6) of beating the grass is fixedlyed connected with power transmission shaft by the mower main body (1) that is connected and fixed hole (3) mower card rope device.

I and II cavity cover (12) (20) is arranged on the mower card rope spare (4) (6), have the rope of beating the grass with auto-lock function to change hole (24) in the outside of I and II cavity cover (12) (20); All the time the rope guide hole (25) of beating the grass that connects is arranged in the inboard of I and II cavity cover (12) (20).

Front end at I and II cavity cover (12) (20) has by nip (26); One-level clamping key body (11) (19) is arranged in I and II cavity cover (12) (20).

Press by nip (26), I and II cavity cover (12) (20) is moved forward, inboard one-level clamping key body (11) (19) compressing one-level cavity inner spring (13) (21) acts on the interior secondary clamping key body of secondary cavity (23) (9) (17), secondary cavity inner spring (14) (22) is oppressed, secondary clamping key body rope hole (10) (18) crosswise fixed card power disappears, and secondary clamping key body rope hole (10) (18) connects the effective aperture and enlarges.

Rope replacing hole (24) loses the auto-lock function to secondary clamping key body rope hole (10) (18) because I and II cavity cover (12) (20) when moving forward, is beaten the grass, and beating the grass rope is changed hole (24) and connected with secondary clamping key body rope hole (10) (18).The rope (7) (15) of beating the grass is gone up power-assisted fixed guide hole (8) (16) and is in place by beat the grass rope replacing hole (24), secondary clamping key body rope hole (10) (18), the rope guide hole (25) of beating the grass, the rope guide shaft fixing unit (2) (5) of beating the grass.

Disappear when pressing nip (26) upward pressure, secondary cavity (23) interior secondary cavity inner spring (14) (22) elastic force effect and mobile secondary clamping key body (9) (17), the straw rope of fighting each other (7) (15) produces crosswise fixed card power because the perforation effective aperture reduces in secondary clamping key body rope hole (10) (18).Hole (24) changed by the rope of beating the grass because the opposition of one-level cavity inner spring (13) (21) is sealed self-locking to secondary clamping key body rope hole (10) (18), to guarantee the fixing of rope (7) (15) of beating the grass.

The rope guide shaft fixing unit (2) (5) of beating the grass is gone up the guiding assurance that power-assisted fixed guide hole (8) (16) is air exercise straw rope (7) (15), and the broadening formation in the outside, power-assisted fixed guide hole (8) (16) has increased the reliability and stability when beating the grass rope (7) (15) work.

Describe by above embodiment, those skilled in the art can be well understood to process of the present invention, and still, the present invention is not limited thereto, any those skilled in the art can think variation all should implement protection scope of the present invention.
