Abstract
The utility model discloses a bolt component for fixing an engine cylinder head housing. The bolt component is characterized by comprising a bolt and a positioning sleeve, wherein the bolt consists of outer-hexagonal bolt head, a polished rod and a screw rod; the polished rod is smaller than the screw rod in outer diameter; the positioning sleeve is movably sleeved outside the polished rod; the pore diameter of the inner hole of the positioning sleeve is larger than the outer diameter of the screw rod; a shrinkage hole is formed in the top of the inner hole of the positioning sleeve and has a pore diameter larger than the outer diameter of the polished rod, but smaller than the outer diameter of the screw rod; and flange surfaces are respectively arranged on the upper and lower end surfaces of the positioning sleeve. The bolt component facilitates the mounting and dismounting of the engine cylinder head housing and effectively avoids damage to the cylinder head housing.
Description
Technical field
The utility model relates to a kind of bolt assembly of stationary engine cylinder cap case.
Background technique
The cylinder cap case of motor car engine adopts aluminum hull or thin-walled steel plate or working of plastics usually, is fixed by bolts to when mounted on the motor body, will put abutment sleeve between engine cylinder cover and cylinder cap case.Because bolt and abutment sleeve are two fully independently parts,, cause the part disappearance easily so in the installing/dismounting process of cylinder cap case, can make troubles; In addition, when stationary cylinder housing shell, bolt head can directly be pressed on the cylinder cap case, if firmly bigger than normal, as easy as rolling off a log distortion of cylinder cap case or the cracking of making causes damaging.
Summary of the invention
In view of the deficiency that background technique exists, the purpose of this utility model is intended to provide a kind of installing/dismounting that makes things convenient for the cylinder cap case, avoids the cylinder cap case is caused the bolt assembly of the stationary engine cylinder cap case of damage.
The utility model is implemented by following technical solution:
The bolt assembly of stationary engine cylinder cap case, it is characterized in that: comprise bolt and abutment sleeve, bolt is made up of outer-hexagonal head, polished rod and screw portion, the polished rod external diameter is less than the screw rod external diameter, described abutment sleeve is movably set in outside the polished rod, the endoporus aperture of abutment sleeve is greater than the screw rod external diameter, and the endoporus of abutment sleeve forms shrinkage cavity at tip position, and the aperture of shrinkage cavity is greater than the polished rod external diameter but less than the screw rod external diameter.The upper and lower end face of described abutment sleeve has flanged surface.
Bolt assembly of the present utility model, bolt and abutment sleeve are the siamese parts that flexibly connects, thereby have made things convenient for the installation and removal of engine cylinder cover case; In addition by the utility model to the cylinder cap case fixedly the time, be that the upper flange surface of abutment sleeve compresses the cylinder cap case rather than the head of bolt, because the abutment sleeve upper flange surface has bigger area, so be difficult for making distortion of cylinder cap case or cracking, effectively avoid the cylinder cap case is caused damage.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, the bolt assembly of stationary engine cylinder cap case of the present utility model, comprise bolt and abutment sleeve 7, bolt is made up of outer-hexagonal head 1, polished rod 2 and screw rod 3 parts, polished rod 2 external diameters are less than screw rod 3 external diameters, described abutment sleeve 7 is movably set in outside the polished rod 2, endoporus 6 apertures of abutment sleeve are greater than screw rod 3 external diameters, the endoporus of abutment sleeve forms shrinkage cavity 5 at tip position, the aperture of shrinkage cavity 5 is greater than polished rod 2 external diameters but less than screw rod 3 external diameters, the upper and lower end face of described abutment sleeve has upper flange surface 4 and lower flange face 8.
Bolt assembly of the present utility model, when stationary engine cylinder cap case, the lower flange face bottom of abutment sleeve can be pressed in engine cylinder and cover, and the upper flange surface bottom can be pressed on the cylinder cap case, the excessive damage that the cylinder cap case is caused distortion or cracking forms of can avoiding exerting oneself; When dismounting engine cylinder cover case, be connected as long as unclamp with the bolt of motor body, whole bolt assembly will be removed with the cylinder cap housing and can not be scattered together.So the utility model has greatly made things convenient for the installation and removal of engine cylinder cover case, and effectively avoid the cylinder cap case is caused damage.
Claims (2)
1. the bolt assembly of stationary engine cylinder cap case, it is characterized in that: comprise bolt and abutment sleeve, bolt is made up of outer-hexagonal head, polished rod and screw portion, the polished rod external diameter is less than the screw rod external diameter, described abutment sleeve is movably set in outside the polished rod, the endoporus aperture of abutment sleeve is greater than the screw rod external diameter, and the endoporus of abutment sleeve forms shrinkage cavity at tip position, and the aperture of shrinkage cavity is greater than the polished rod external diameter but less than the screw rod external diameter.
2. the bolt assembly of stationary engine cylinder cap case as claimed in claim 1 is characterized in that: the upper and lower end face of described abutment sleeve has flanged surface.
