Abstract
The utility model relates to a lawn mower handrail height quick adjustment device which comprises a lawn mower main body. A lower handrail is obliquely arranged on the rear side of the lawn mower main body. The side face of the upper portion of the lower handrail is connected with an upper handrail through an adjusting disk. The upper side of the upper handrail is connected with a stretchable handle. According to the lawn mower handrail height quick adjustment device, a contrate gear structure is used, and the height of each handrail is adjusted through the adjustment of the angle of the contrate gear structure. Therefore, the lawn mower handrail height quick adjustment device is convenient to use, practical, simple in overall structure, easy to manufacture, simple and convenient to operate, not prone to damage and suitable for multiple types of lawn mowers.
Description
Technical field
The utility model relates to a kind of lawn machine handrail height fast adjuster.
Background technology
Lawn machine handrail height is generally fixing, during use, because user's height difference or geopotentia change, therefore lawn machine operation inconvenience need to change handrail height or angle, the lawn machine of Cun Zaiing adopts the nodular expansion link to regulate handrail height more on the market, but in use,, fracture easily because expansion link intensity is relatively poor, and expansion link is longer, operation inconvenience.
Summary of the invention
In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of lawn machine handrail height fast adjuster convenient and practical, easy and simple to handle.
To achieve these goals, the technical solution of the utility model is: a kind of lawn machine handrail height fast adjuster, comprise lawn machine main body, described lawn machine main body rear side is tiltedly installed with down handrail, described handrail upper side down is connected with last handrail by adjustment disk, the described handrail upside of going up is connected with retractable handle, can be by handrail height in adjustment disk and the multiple adjusting of retractable handle.
Further, described adjustment disk comprises first contrate gear that is arranged on down the outside, handrail upper end and second contrate gear that is arranged on inboard, handrail lower end, described first contrate gear and second contrate gear are meshing with each other, described first contrate gear and the second contrate gear axle center are horizontally arranged with connecting rod, hold up the lower end arranged outside that handle is arranged on described, the rounded ends off-centre on described interlinking lever end and handle top is hinged, regulating the distance between first contrate gear and second contrate gear, and then regulate and go up handrail angle and height.
Further, described interlinking lever end is fixed on down the handrail upper end by nut.
Further, the described handrail upper end mouth of pipe of going up is less than the retractable handle mouth of pipe, and described retractable handle is set in the handrail two ends, scalable adjusting.
The utlity model has following advantage: adopt the contrate gear structure, by regulating its angle, adjust handrail height, convenient and practical, overall structure is simple, and is easy to manufacture, easy and simple to handle, not fragile, is applicable to multiple lawn machine.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Fig. 2 is the front view of the utility model embodiment.
Fig. 3 is the A detail view of the utility model embodiment.
Among the figure: 1-lawn machine main body, handrail under the 2-, 3-handle, 4-second contrate gear, the last handrail of 5-, 6-retractable handle, 7-connecting rod, 8-first contrate gear.
Embodiment
Below in conjunction with drawings and Examples the utility model is further elaborated.
With reference to figure 1, a kind of lawn machine handrail height fast adjuster, comprise lawn machine main body 1, described lawn machine main body 1 rear side is tiltedly installed with down handrail 2, described handrail 2 upper side down are connected with last handrail 5 by adjustment disk, described handrail 5 upsides of going up are connected with retractable handle 6, can be by 5 height of handrail in adjustment disk and the retractable handle 6 multiple adjustings.
In conjunction with Fig. 2 and Fig. 3, in the present embodiment, described adjustment disk comprises first contrate gear 8 that is arranged on down the outside, handrail 2 upper ends and second contrate gear 4 that is arranged on inboard, handrail 5 lower end, described first contrate gear 8 and second contrate gear 4 are meshing with each other, described first contrate gear 8 and second contrate gear, 4 axle center are horizontally arranged with connecting rod 7, the described handrail lower end arranged outside that goes up has handle 3, the rounded ends off-centre on described connecting rod 7 ends and handle 3 tops is hinged, regulating the distance between first contrate gear 8 and second contrate gear 4, and then regulate and go up handrail 5 angles and height.
In the present embodiment, described connecting rod 7 ends are fixed on down handrail 2 upper ends by nut.
In the present embodiment, the described handrail 5 upper end mouths of pipe of going up are less than retractable handle 6 mouths of pipe, and described retractable handle 6 is set in handrail 5 two ends, scalable adjusting.
The present embodiment operation principle is as follows: handle 3 is broken into two with one's hands, make the rounded ends of handle 3 rotate to the less end of eccentric distance near last handrail 5, first contrate gear 8 and second contrate gear 4 are not subjected to handle 3 pressure separately, rotation this moment is regulated and is gone up handrail 5 angles, when last handrail 5 is highly suitable, handle 3 is depressed, first contrate gear 8 and second contrate gear 4 are compressed, simultaneously, handrail 5 is withstood in the end self-locking that the rounded ends eccentric distance of handle 3 is bigger, last handrail 5 just is fixed on down on the handrail 2, and also can regulate its height once more by regulating the retractable handle 6 of going up handrail 5 upper ends this moment.
The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
