Abstract
The utility model discloses a cylinder cover which comprises a cylinder cover body, a first annular groove and a second annular groove which are used for being combined with a sealing ring are formed in the inner wall of the cylinder cover body, the first groove and the second groove are formed in the near end portion inside the cylinder cover body and are the same in diameter, and a convex groove which is larger than the first groove and the second groove in diameter is further formed in the inner wall of the cylinder cover body and located between the first groove and the second groove. The cylinder cover has the advantage that the sealing ring can not fall off easily.
Description
Technical field
The utility model relates to a kind of cylinder constituent elements, and more particularly, it relates to the cylinder head in a kind of cylinder constituent elements.
Background technique
Cylinder refers in internal-combustion engine or external-combustion engine, allows piston occupy in the inner, allows its container up and down reciprocatingly.According to the size of the required power of work, determine thrust and the pulling force on piston rod.While selecting cylinder thus, should make the ouput force of cylinder that surplus is slightly arranged.If cylinder diameter selects little, ouput force is inadequate, the cylinder cisco unity malfunction; But cylinder diameter is excessive, make not only that equipment is heavy, cost is high, air consumption increases simultaneously, causes energy waste.When jig Design, should adopt boosting mechanism, to reduce the size of cylinder as far as possible.
Cylinder is comprised of cylinder barrel, cylinder cap, piston, piston rod and Sealing etc.End cap is provided with the intake and exhaust port, and what have also is provided with damping mechanism in end cap.The bar side end cap is provided with seal ring and dust ring, from piston rod, outwards leaks gas and prevents that external dust from sneaking in cylinder preventing.Cylinder cap is arranged on above the cylinder body of cylinder barrel, from the top seal cylinder and form firing chamber.It often contacts with high-temperature high-pressure fuel gas, therefore bears very large heat load and mechanical load.The sealability of cylinder head is particularly important.In the routine work process, cylinder head and seal ring are used simultaneously.In cylinder head, be provided with the circular pit of two equal diameters near cover port.Seal ring is connected with the second groove by the first groove with cylinder head at present, and the cylinder cap of this kind setting in use easily allows seal ring break away from away.
The model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of cylinder head of seal ring difficult drop-off.
For achieving the above object, the utility model provides following technological scheme:
A kind of cylinder head, include the cylinder cap body, described cylinder cap inner body wall is provided with the first groove and the second groove that are annular for being combined with seal ring, described the first groove and the second groove are located at cylinder cap body interior close end place and equal diameters, on described cylinder cap inner body wall, also be provided with the tongue that diameter is greater than the first groove and the second groove, described tongue is located between the first groove and the second groove.
By adopting technique scheme, tongue is located between the first groove and the second groove that is annular, and the tongue diameter is greater than the first groove and the second groove makes between the first groove and the second groove to form a depressed part, when seal ring being packed into to the cylinder cap body interior, seal ring just is absorbed in the tongue inside of cylinder cap body interior, so just can reach the purpose of seal ring difficult drop-off.
As further improvement in the technical proposal:
Described tongue is the convex surface groove, and drift angle is more than or equal to 0 ° and is less than or equal to 180 °.
The drift angle of described convex surface groove is more than or equal to 0 ° and is less than or equal to 90 °.
By adopting technique scheme, the drift angle size of convex surface groove needs to change by installation.
The other end of relative the second groove of described the first groove is provided with annular chamfer.
By adopting technique scheme, can not only prevent that when mounted dust from entering and can allow lid mouthful better embed and install.
The accompanying drawing explanation
Fig. 1 is the cutting plane of model utility cylinder head plan view;
Fig. 2 is model utility cylinder head A section enlarged view.
Reference character:
1, cylinder cap body; 2, Gai Kou; 31, the first groove; 32, the second groove; 4, tongue.
Embodiment
Referring to figs. 1 through cylinder head embodiment of the present utility model is described further.
As shown in Figure 1, cylinder head in the present embodiment, include cylinder cap body 1, described cylinder cap body 1 inwall is provided with the first groove 31 and the second groove 32 that are annular for being combined with seal ring, described the first groove 31 and the second groove 32 are located at cylinder cap body 1 inner proximal section place and equal diameters, on described cylinder cap body 1 inwall, also be provided with the tongue 4 that diameter is greater than the first groove 31 and the second groove 32, described tongue 4 is located between the first groove 31 and the second groove 32.
As shown in Figure 2, tongue 4 can be set to the convex surface groove, and its drift angle is more than or equal to 0 ° and is less than or equal to 180 °, and the drift angle of described convex surface groove also can be more than or equal to 0 ° and be less than or equal to 90 °.The drift angle size of tongue 4 needs to change by installation.
The other end of relative the second groove 32 of described the first groove 31 is provided with annular chamfer.Can not only prevent that so when mounted dust from entering and can allow lid mouthful 2 better embeddings install.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
