Abstract
The utility model relates to a connecting piece for quickly changing a drive shaft, which comprises a first screw cap, a box body, a second screw cap, a first spring, a push plate, a first sliding block, a lining, a second spring, a guide rod, a first bolt, a second bolt, a limiting pin, a handle, a gasket, an aluminum pipe, a spline top guide, a drive shaft and a second sliding block, wherein the push plate is installed on the box body, and the bottom of the push plate presses against the protruded part at the right side of the box body through the first spring; the lining and the second spring are sheathed on the upper part of the guide rod from the outside to the inside, and the first sliding block is riveted on the upper end of the guide rod; and lower side of the push plate and the second sliding block are in injection molding integrally, and the second sliding block and the first sliding block are connected. The connecting piece can realize quick change of a drive shaft assembly and an anti-loosening function on the premise of not influencing the transmitting effect of driving torque.
Description
Technical field
The utility model belongs to graden machine accessory field, particularly relates to a kind of live axle and changes coupling fast.
Background technique
Attractive in appearance and satisfy the demand on athletic ground for gardens, various graden machines are widely used, and comprise mowing machine, hedge machine, edge cutter, chain saw etc.The basic structure of above-mentioned graden machine is that a motor drives the work of a function head by live axle.A kind of connected piece structure that can realize the shared motor of above-mentioned graden machine has appearred in the market, promptly connect live axle and coupling can be applied to the difference in functionality head and change graden machines such as mowing machine, hedge machine, edge cutter, chain saw into, realized the function of a tractor serves several purposes with a motor.
This kind device exists some defectives: the coupling connecting mode is too complicated, inconvenient operation, and live axle is changed inconvenient; Coupling connects insecure, gets loose easily etc.
The model utility content
Technical problem to be solved in the utility model provides a kind of live axle and changes coupling fast, can realize the quick replacing of drive shaft assembly and anti-loose function under the prerequisite that does not influence driving torque transmission effect.
The technological scheme that its technical problem that solves the utility model adopts is: provide a kind of live axle to change coupling fast, comprise first nut, casing, second nut, first spring, push pedal, first slide block, lining, second spring, guide rod, first bolt, second bolt, position limit pin, handle, packing ring, aluminum pipe, spline top guide, the live axle and second slide block is characterized in that: described push pedal is installed on the casing, and the push pedal bottom props up casing right side jut by first spring; The lining and second spring are placed in guide rod top from outside to inside, guide rod upper end riveted joint first slide block; The push pedal downside and second slide block are injected into one, and second slide block is connected with first slide block.
There is the inclined-plane in described lower end of the guide rod portion.
Beneficial effect
The utility model is simple in structure, and is easy to operate, and personnel are difficult to destroy coupling in operation.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiments only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As Figure 1-3, a kind of live axle is changed coupling fast, first nut 9, casing 10, second nut, 11, the first springs 12, push pedal 13, the first slide blocks 14, lining 15, the second springs 16, guide rod 17, the first bolts 18, second bolt 19, position limit pin 20, handle 21, packing ring 22, aluminum pipe 23, spline top guide 24, the live axle 25 and second slide block 26 is characterized in that: described push pedal 13 is installed on the casing 10, and push pedal 13 bottoms prop up casing 10 right side juts by first spring 12; The lining 15 and second spring 16 are placed in guide rod 17 tops from outside to inside, and first slide block 14 is riveted in guide rod 17 upper ends; Push pedal 13 downsides and second slide block 26 are injected into one, and second slide block 26 is connected with first slide block 14.
There is the inclined-plane in described lower end of the guide rod portion.
Drive shaft assembly comprises aluminum pipe 23, spline top guide 24 and live axle 25, when drive shaft assembly inserts casing 10, because guide rod 17 head inclined-planes face drive shaft assembly, it can apply an axial force to guide rod 17, makes guide rod 17 by jack-up, when drive shaft assembly is inserted into, because the rebound effect of second spring 16 is inserted in the positioning hole of drive shaft assembly guide rod 17, thereby form being connected of casing 10 and drive shaft assembly.Promoting push pedal 13, the second slide blocks 26 with the arrow direction in figure two can move upward by drive first slide block 14, thereby makes guide rod 17 break away from the positioning hole of drive shaft assemblies, just drive shaft assembly can be separated with casing 10.
