Description
Technical field
The invention belongs to grass trimmer fields, and in particular to lawnmower blade rapid installation device.
Background technology
Currently, grass mower, which is a kind of common afforestation, cuts careless tool, structure is by a grass mower head mostly
The compositions such as the blade assembly of grass mower head bottom are mounted on detachable, in order to facilitate between blade assembly and grass mower head
Connection installation and ensure that the mainshaft gear in grass mower head can be transferred to power is satisfactory on blade assembly, usually also
The accessories such as blade cover board, cam gear ring and blade fixed plate can be added to carry out the installation of blade assembly.However, when above-mentioned
After accessory increases, the interconnection between several accessories is often caused to cannot achieve Fast Installation and quickly tear open
It unloads, to which the replacement and repair to blade assembly bring very big inconvenience.
Invention content
The technical problems to be solved by the invention are just to provide a kind of convenient lawnmower blade of assembly or disassembly and quickly pacify
Assembling device.
In order to solve the above technical problems, the present invention adopts the following technical scheme that：Lawnmower blade rapid installation device, including
Head and the blade assembly for being connected to head lower part, blade assembly includes lower housing, and limit sliding chutes, head are provided in lower housing
Including upper shell, the both sides of head are respectively arranged with the elastic button across upper shell, and limit protrusion is provided on elastic button,
Limit protrusion passes outwards through upper shell and is clamped with limit sliding chutes.
Further, upper shell includes outer cover and is connected to outer cover lower part to stretch into the positioning plate in lower housing, positioning plate
The step for being formed between outer cover and being offseted at the top of lower housing.
Further, it is provided with the guide protrusions for surrounding limit sliding chutes in lower housing, is provided on positioning plate convex for being oriented to
Play the guide groove of sliding.
Further, the through-hole passed through for limit protrusion is provided on positioning plate, through-hole is located in guide groove.
Further, support plate is provided in head, the both sides of support plate are both provided with guiding fixed column, elastic button packet
Include the button for being socketed in the elastic element being oriented in fixed column and being slidably connected at guiding fixed column end.
Further, button is provided with anti-rotation protrusion towards the side for being oriented to fixed column, is oriented to the end set of fixed column
There are the anti-rotation groove for preventing button from being rotated on being oriented to fixed column, anti-rotation protrusion and anti-rotation groove cooperation.
Further, positioning protrusion is provided on button, being provided in support plate, which prevents button to be detached from, is oriented to fixed column
Limit hook, limit hook coordinate with positioning protrusion.
Further, the positioning runner slided for positioning protrusion is provided on limit hook.
Further, blade assembly includes bottom plate, is arranged fluted on bottom plate, and the bottom of head is provided with and groove coordinates
Convex ribs.
Further, there are two limit protrusion, two limit protrusions are located at the both sides of button for the lower part setting of button,
The free end of limit protrusion is provided with guiding surface, and the angle between guiding surface and the top surface of limit protrusion is less than 90 degree.
Compared with prior art, the beneficial effects of the invention are as follows：
1, when head and blade assembly are installed, elastic button need to be only pressed, elastic button drives limit protrusion contracting
Into inside positioning plate, then pushing down on head or push up blade assembly so that the lower part of upper shell is stretched into lower housing,
Then the hand for pressing head two-side elastic button is unclamped, housing direction moves elastic button upwards under the elastic force effect of spring,
With button, upward housing direction moves the limit protrusion being connected on elastic button jointly, and limit protrusion passes through upper shell and stretches into
In limit sliding chutes, head and upper shell install.When needing to dismantle head and upper shell, the button of head both sides is pressed,
So that limit protrusion is retracted with button inside positioning plate, you can pull up head or pull downward on blade assembly.By head and
Blade assembly detaches.Head is connected by limit protrusion and blade assembly, limit protrusion are connected on elastic button and with elasticity
Button moves jointly, only need to press elastic button, you can limit protrusion the stretching on head that control is connected on elastic button
Contracting, and then control whether limit protrusion connects head and blade assembly, realize Fast Installation of the blade assembly on head
With fast quick-detach, it is convenient for the replacement and repair of blade assembly, saves replacement and maintenance time.
When 2, assembling head and blade assembly, if the top of lower housing offsets with step, upper shell and lower housing dress are indicated
With finishing, plays the role of assembly positioning and prevent head and blade assembly from relatively moving.
3, when head and blade assembly are installed, by the guiding on the guide groove alignment lower housing inner wall on positioning plate
Then protrusion pushes down on head or pushes up blade assembly so that guide protrusions are convex to being oriented to along guide groove upward sliding
Rise top and guide groove at the top of offset, indicate upper shell and lower housing assembly finish, the cooperation of guide groove and guide protrusions
So that head and blade assembly when being assembled, realize rapid alignment, it is convenient for the quick assembling of head and blade assembly, assembly
Afterwards, the side wall of guide protrusions and guide groove offsets, and prevents the displacement on head and blade assembly occurred level direction, ensures assembly
Precision.
4, it is oriented to the track that fixed column provides sliding to the button of elastic button so that elastic button remains at one
A fixed track is moved, and when preventing from pressing elastic button, elastic button is because unbalance stress shifts so that elasticity
Button is directed at the fixed position of upper shell always, ensures the stability of elastic button.
5, anti-rotation protrusion is connected in anti-rotation groove, prevents elastic button from being rotated on being oriented to fixed column, and guarantee is connected to bullet
Limit protrusion on property button is directed at limit sliding chutes always.
6, under the effect of the elastic force of spring, the both ends of the positioning protrusion on button and the end of limit hook offset, limit
Grab prevents button to be detached under the effect of elasticity and is oriented to fixed column.
7, when head and blade assembly are in assembled state, convex ribs are clamped in a groove, pass through the card of convex ribs and groove
It connects, the displacement dislocation occurred on circumferencial direction when reducing gear cooperation improves assembly precision.
8, the angle between guiding surface and the top surface of limit protrusion is less than 90 degree, and guiding surface is downward so that limit convex
When rising across through-hole, without being directed at through-hole completely in the vertical direction, allow, there are certain error, to pass through convenient for limit protrusion
Through-hole on upper shell.
Compared with prior art, the present invention connects head by limit protrusion and blade assembly, limit protrusion are connected to bullet
Property button on and move jointly with elastic button, only need to press elastic button, you can control is connected to the limit on elastic button
Protrusion is flexible on head, and then controls whether limit protrusion connects head and blade assembly, realizes that blade assembly exists
Fast Installation on head and fast quick-detach are convenient for the replacement and repair of blade assembly, save replacement and maintenance time.
