Abstract
The utility model relates to a wrench for dismounting an air gate of an engine. The utility model is composed of a working pressing plate (1), a pressing handle (2), a trough (3) on the working pressing plate (1), a lock hole (4), etc. The utility model has the characteristics of simple structure, and labor saving and convenient use because the lever structure which is composed of the working pressing plate and the pressing handle is used; the utility model can be used for maintenance of engine valves of various overhead type automobiles.
Description
The utility model belongs to automotive service set, and specifically it is a kind of wrench for dismounting that is used for the dismounting automotive engine valves.
In automobile maintenance industry, the dismounting of automotive engine valves mainly is to cooperate by many people firmly to suppress, and just can carry out dismounting.This traditional dismounting mode is very inconvenient, and very requires great effort.By retrieval, also find no the instrument that is used for the automotive engine valves dismounting that closes.
The purpose of this utility model provides a kind of automotive engine valves wrench for dismounting simple in structure, to satisfy the needs of automobile maintenance industry.
The purpose of this utility model can reach by following structures.The utility model has a work pressing plate, is connected with the pressurization hand lever at an end of work pressing plate, has an elongated slot that can put in screw rod at the other end of work pressing plate, has a lockhole that can put in the engine valve microcephaly at the middle part of work pressing plate.So in use, elongated slot on the work pressing plate can be put in the studding screw rod that has nut on the engine fuselage, nut spacingly makes it become the pressurization fulcrum it, the lockhole at work pressing plate middle part is aimed at engine valve, firmly depress the pressurization hand lever, make the engine valve spring compression and the engine valve microcephaly is exposed from lockhole, the engine valve locking plate just unclamps naturally, take out the engine valve locking plate, unclamp spanner, this valve has just disassembled.The installation and removal method of engine valve is basic identical, different just after compressing valve spring, install the engine valve locking plate, unclamp spanner and get final product.
In order to prevent the swing of engine valve spring when pressurizeing, the utility model can be slightly larger than on the position of engine valve spring radius at radius around the lockhole of work pressing plate middle part stretches the spring limiting block rib that strip or circle bar shaped are arranged downwards.So in use, spring limiting block rib just can block engine valve spring makes it the swing situation not occur when pressurization, makes the utility model more practical.
In order to make the utility model adaptability stronger, the utility model can extend upwardly the fulcrum rib on the elongated slot limit of work pressing plate termination, and so in use just can adapt to engine studding screw rod middle part does not have thread and make on the nut situation less than the bottom.
The utility model makes to the utlity model has simple in structure, the laborsaving characteristics easily of use, thereby has reached the purpose of this utility model owing to the lever construction that has adopted work pressing plate and pressurization hand lever to constitute.
Accompanying drawing has provided an embodiment of the present utility model.Further specify concrete structure of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing 1 is a structural representation front view of the present utility model, and accompanying drawing 2 is a structural representation vertical view of the present utility model.Among the figure, (1) is the work pressing plate, end at work pressing plate (1) is connected with pressurization hand lever (2), the other end at work pressing plate (1) has an elongated slot (3) that can put in screw rod, have a lockhole (4) that can put in the engine valve microcephaly at the middle part of work pressing plate (1), being slightly larger than to stretch downwards on the position of engine valve spring radius at radius around work pressing plate (1) the middle part lockhole (4) has the spring of strip limiting block rib (5), and elongated slot (3) periphery in work pressing plate (1) termination has extended upwardly fulcrum rib (6).
The utility model has vast market prospect applicable to the maintenance of various overhead type automotive engine valves.
Claims (3)
1, a kind of engine valve wrench for dismounting, it is characterized in that having a work pressing plate (1), end at work pressing plate (1) is connected with pressurization hand lever (2), the other end at work pressing plate (1) has an elongated slot (3) that can put in screw rod, has a lockhole (4) that can put in the engine valve microcephaly at the middle part of work pressing plate (1).
2,, it is characterized in that being slightly larger than and stretch the spring limiting block rib (5) that strip or circle bar shaped are arranged on the position of engine valve spring radius downwards at radius around work pressing plate (1) the middle part lockhole (4) according to the described engine valve wrench for dismounting of claim 1.
3,, it is characterized in that having extended upwardly fulcrum rib (6) at elongated slot (3) periphery in work pressing plate (1) termination according to claim 1 or 2 described engine valve wrench for dismounting.
