Abstract
The utility model discloses an air inlet pipe bolt for an engine. The air inlet pipe bolt for the engine is characterized in that a hexagonal screw head is arranged at the upper end of a screw rod, a pressing cap is arranged on the periphery of the connecting position of the hexagonal screw head and the screw rod, a circle of locking teeth is evenly distributed and arranged on the end face of the bottom portion of the pressing cap, and a lead screw portion is arranged on the lower portion of the screw rod. Through the arrangement, the air inlet pipe bolt for the engine is made of special steel, and the locking teeth and special surface treatment guarantee the decay resistance and the locking performance of the bolt.
Description
Technical field
The utility model relates to a kind of standard piece, is a kind of engine intake pipe bolt specifically.
Background technique
Engine intake pipe bolt is the fastening piece high-strength bolt for engine air inlet tube, suction tude belongs to the elongate rod bolt, the engine charge tube vibration easily makes suction tude bolt looseness or fracture, the suction tude bolt exposed is perishable, the necessary intensity of above conditional request suction tude bolt is high, impact toughness good, corrosion-resistant, anti-loosening property good, a part of bolt adopts external import before, is difficult to guarantee above performance.
Summary of the invention
The purpose of this utility model be provide that a kind of intensity is high, impact toughness, the engine intake pipe bolt that corrosion-resistant, anti-loosening property is good.
To achieve these goals, the utility model is provided with hexagonal spiral shell head in the upper end of screw rod, and periphery is provided with pressure cap in the joint of hexagonal spiral shell head and screw rod, on the bottom end face of pressure cap, is laid with all locking teeths, and screw mandrel section is located at the bottom of screw rod.
By above setting, the utility model adopts the special steel manufacture, adopts cold-heading molding, is conducive to guarantee material inside organization.The heat treatment of atmosphere protection multipurpose stove, adjust the carbon potential parameter, guaranteed the product mechanical property.Decay resistance and the anti-loosening property of bolt guaranteed in locking teeth of the present utility model and special surface treatment.
The accompanying drawing explanation
Now the utility model is described in further detail by reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the worm's eye view of Fig. 1.
In figure: 1, screw rod, 2, hexagonal spiral shell head, 3, pressure cap, 4, locking teeth, 5, screw mandrel section.
Embodiment
As shown in Figure 1, 2, 3, the utility model is provided with hexagonal spiral shell head 2 in the upper end of screw rod 1, is provided with pressure cap 3 in hexagonal spiral shell head 2 and the joint periphery of screw rod 1, on the bottom end face of pressure cap 3, is laid with all locking teeths 4, and screw mandrel section 5 is located at the bottom of screw rod 1.By above setting, the utility model is worked under yield situation, unique texture and inherent technical order provide guarantee for the performance of whole motor, the special shape of locking teeth 4 is adapted to the specific (special) requirements of suction tude, under the effect of alternating force, be unlikely to loosening, performance and the anti-loosening properties such as corrosion-resistant are guaranteed in special surface treatment.By installation, verify that this suction tude bolt geometry design is reasonable, integrated performance index is good.
