Abstract
The utility model discloses a buffer starter which comprises a starter body. The two sides of the starter body are provided with pusher dogs, the pusher dogs are fixedly connected with the starter body through sealing gaskets, pressing pieces are arranged in the pusher dogs and are made of elastic materials, the inside and the two ends of each pressing piece form a hollow cavity structure, the hollow cavity of each pressing piece is provided with a buffer spring which is a spiral spring, the height of each buffer spring is smaller than the length of the corresponding pressing piece, when pressed in an elastic mode, the two ends of each buffer spring can extend out of the corresponding pressing piece, and a pusher dog shaft and a crank shaft are connected between the pusher dogs. The buffer starter effectively solves the problems that the rotation speed of an existing starter is not large enough, operation strength is large, a pull rope is tight during starting, and starting cannot be easily achieved; during starting, collision and abrasion among components cannot occur, buffering and energy storing functions are effectively achieved under the action of the buffer springs, recoil force of a cylinder of a gasoline engine is effectively buffered, vibration can be reduced to a great extent and more labor is saved during starting.
Description
Technical field
The utility model relates to a kind of starting drive, particularly a kind of buffer starting device.
Background technique
At present, petrol engine or diesel engine starting mode are hand-pulling recoil startup.When operator's hand pull starting-up, must overcome gas cylinder pressure rotates bent axle, thereby meet the requirements of fire speed, stay cord starter used is in the time starting, pull rope sheave, the direct flywheel driven of rope sheave and bent axle rotate, fuel engine is started, but fly wheel assembly inertia is large, start more difficult, need to pull energetically rope sheave, and large to the impact force of whole starting drive in the time starting, stay cord has obvious back attack phenomenon, so just likely cause service time short, maintenance frequency is many, change frequent, also higher to the material requirements of starting drive thus, be unfavorable for economic saving.
Model utility content
The technical problems to be solved in the utility model is: overcome the problems referred to above, provide a kind of starter rotating speed enough, operating force is little, buffer starting device in labour-saving when startup.
To achieve these goals, the technical solution adopted in the utility model is such: buffer starting device of the present utility model, comprise starter, starter both sides are equipped with pusher dog, pusher dog is fixedly connected with starter by sealing gasket, in pusher dog, be provided with compressing tablet, compressing tablet adopts elastic material to make, compressing tablet inside and two ends form hollow cavity structure, in its compressing tablet hollow cavity, be provided with damping spring, damping spring is helical spring, the height of damping spring is less than compressing tablet length, damping spring two ends can be extended out outside compressing tablet in the time suppressing, between pusher dog, be connected with respectively pusher dog axle and bent axle, bent axle is vertical structure setting, bent axle is fixedly connected on pusher dog, between pusher dog and pusher dog axle, adopt embedded connection, pusher dog is provided with startup ratchet wheel, starting ratchet wheel is rotationally connected by bearing and pusher dog, start between ratchet wheel and pusher dog and be provided with rope sheave, rope sheave is with to start ratchet wheel relatively independent and relatively rotate, rope sheave two ends are individually fixed in and start on ratchet wheel and pusher dog, in rope sheave, be provided with Returnning spring, between pusher dog, be provided with cylinder, the cylinder structure that takes the shape of the letter U, cylinder is fixedly connected with pusher dog and rope sheave.
Further, as a kind of concrete structural type, the utility model is provided with positioning link between cylinder and pusher dog and rope sheave, and is fixedly connected with by positioning link between cylinder and pusher dog and rope sheave.
Further, as a kind of concrete structural type, the utility model is provided with groove at rope sheave end face, the built-in rope sheave plain cushion of its end face groove.
Compared with prior art, the utility model has the advantage of: the utility model buffer starting device efficiently solves that existing starter rotating speed is inadequate, and operating force is large, and when startup, stay cord is tight, cause the problem that is not easy startup, in the time starting, between each parts, can not cause collision and wearing and tearing, under the effect of damping spring, can play the effect of effective buffering and energy storage, thereby effectively cushion the recoil force from gasoline engine cylinder, can, reducing vibration in degree greatly, start more laborsaving.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
In figure: 1. starter, 2. pusher dog, 3. pusher dog axle, 4. compressing tablet, 5. damping spring, 6. starts ratchet wheel, 7. bent axle, 8. rope sheave, 9. Returnning spring, 10. cylinder.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The preferred embodiment of the utility model buffer starting device as shown in Figure 1, comprise starter 1, starter 1 both sides are equipped with pusher dog 2, pusher dog 2 is fixedly connected with starter 1 by sealing gasket, in pusher dog 2, be provided with compressing tablet 4, compressing tablet 4 adopts elastic material to make, compressing tablet 4 inside and two ends form hollow cavity structure, in its compressing tablet 4 hollow cavities, be provided with damping spring 5, damping spring 5 is helical spring, the height of damping spring 5 is less than compressing tablet length, damping spring 5 two ends can be extended out outside compressing tablet 4 in the time suppressing, between pusher dog 2, be connected with respectively pusher dog axle 3 and bent axle 7, bent axle 7 is vertical structure setting, bent axle 7 is fixedly connected on pusher dog 2, between pusher dog 2 and pusher dog axle 3, adopt embedded connection, pusher dog 2 is provided with and starts ratchet wheel 6, starting ratchet wheel 6 is rotationally connected by bearing 7 and pusher dog 2, start between ratchet wheel 6 and pusher dog 2 and be provided with rope sheave 8, rope sheave 8 is with to start ratchet wheel 6 relatively independent and relatively rotate, rope sheave 8 two ends are individually fixed in and start on ratchet wheel 6 and pusher dog 2, in rope sheave 8, be provided with Returnning spring 9, between pusher dog 2, be provided with cylinder 10, cylinder 10 structure that takes the shape of the letter U, cylinder 10 is fixedly connected with pusher dog 2 and rope sheave 8, between cylinder 10 and pusher dog 2 and rope sheave 8, be provided with positioning link, and be fixedly connected with by positioning link between cylinder 10 and pusher dog 2 and rope sheave 8, rope sheave 8 end faces are provided with groove, the built-in rope sheave plain cushion of its end face groove.
