Abstract
Disclosed is a double-end flange bolt for fixing a cover of an engine. The problems that mounting the cover on the engine is troublesome, and connecting is unreliable are solved. The double-end flange bolt comprises a bolt body, and the bolt body comprises a first threaded part, a flange part and a second threaded part. A hexagonal rotation part is arranged between the first threaded part and the flange part. The bolt body is made of carbon boracic steel. The tensioning strength of the bolt body is 784-980 N/mm<2>, and the hardness of the bolt body is HRC 22-32. The double-end flange bolt for fixing the cover of the engine has the advantages that the design of the first threaded part and the second threaded part can well and reliably enable the two parts to be fixedly connected, and meanwhile a good loosening and positioning effect can be achieved. In addition, the flange part and the rotation part are arranged, the work of a monkey wrench can be made to be convenient, and mounting is fast and reliable.
Description
Technical field
The utility model relates to a kind of fixing double end flange bolt of motor lid that is used for.
Background technique
(English: Engine), be called engine again, be a kind ofly can normally be converted into mechanical energy to the machine of the another kind of more useful energy of being converted into of a kind of form to chemical energy to motor.Sometimes it both had been applicable to power generating apparatus, also can refer to comprise the entire machine of power plant.Common engine structure complexity, engine interior spare is various, during engine operation vibrations bigger, so that being connected usually appears in the common bolt of the lid of motor and the fixedly employing of housing is unreliable, fracture easily, and adopt plain bolt stationary engine lid cumbersome.
Summary of the invention
For solving the installation of the lid on motor trouble in the background technique, connect insecure problem, the utility model provides a kind of fixing double end flange bolt of motor lid that is used for.
The technical solution of the utility model is: a kind of fixing double end flange bolt of motor lid that is used for, comprise bolt body, comprise first screw section, flange part and second screw section on the described bolt body, the reach of identical and first screw section of the Major Diam of the Major Diam of described first screw section and second screw section is less than the reach of second screw section, be provided with hexagonal rotation section between described first screw section and the flange part, described bolt body adopts the carbon element boron-containing steel, and the Zhang Qiangdu that draws of described bolt body is 784-980N/mm
2, the hardness of described bolt body is HRC22-32.
As a kind of improvement of the present utility model, be provided with joint between the described flange part and second screw section.
As further improvement of the utility model, the Zhang Qiangdu that draws of described bolt body is 882N/mm
2
As further improvement of the utility model, the hardness of described bolt body is HRC27.
The beneficial effects of the utility model are, the design of first bolt part and second bolt part can be fine, reliably two parts are fixedlyed connected, can play simultaneously and well loosen and locating effect, and flange part of the present utility model and rotation section be provided with can the portable propelling spanner work, make install quick more, reliable.
Description of drawings
Accompanying drawing 1 is the utility model embodiment's a structural representation.
Accompanying drawing 2 is the left view of accompanying drawing 1.
Among the figure, 1, bolt body; 11, first screw section; 12, flange part; 13, second screw section; 14, rotation section; 15, joint.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described further:
By Fig. 1 in conjunction with shown in Figure 2, a kind of fixing double end flange bolt of motor lid that is used for, comprise bolt body 1, comprise first screw section 11 on the described bolt body 1, the flange part 12 and second screw section 13, the reach of identical and first screw section 11 of the Major Diam of the Major Diam of described first screw section 11 and second screw section 13 is less than the reach of second screw section 13, be provided with 14(rotation section, hexagonal rotation section between described first screw section 11 and the flange part 12 and be meant the position that drives the bolt body rotation), be provided with joint 15 between the described flange part 12 and second screw section 13.Described bolt body 1 adopts carbon element boron-containing steel (be meant and contain trace B in the carbon steel), and the Zhang Qiangdu that draws of described bolt body 1 is 784-980N/ mm
2, specifically, the Zhang Qiangdu that draws of described bolt body 1 is 882N/ mm
2Specifically, the hardness of described bolt body 1 is HRC22-32, and the hardness of described bolt body 1 is HRC27.The design of first bolt part and second bolt part can be fine, reliably two parts are fixedlyed connected, can play simultaneously and well loosen and locating effect, and flange part of the present utility model and rotation section be provided with can the portable propelling spanner work, make install quick more, reliable.
Every technician's notice: though the utility model is described according to above-mentioned embodiment; but invention thought of the present utility model is not limited in this model utility; the repacking of any utilization inventive concept all will be included in this patent scope of patent protection.
