The utility model discloses an integrated bolt's flat pad can not break away from the bolt, and the two integration sets up, when using, makes things convenient for operating personnel's operation greatly to in the use, the bolt is difficult not hard up, has avoided arousing the incident because of bolt looseness.
Description
Technical field
The utility model relates to a kind of mechanical parts, particularly relates to a kind of integration bolt.
Background technique
Current ev industry is subject to the support energetically of national government, and electric automobile market is also just more and more prosperous.Because lead-acid battery is one of electric vehicle product main parts size, therefore, the demand for the storage battery of electric vehicle is increasing.
Storage battery common is at present lead-acid battery, and storage battery is made up of positive and negative pole plate, dividing plate and electrolytic solution, battery case and connection strap (or plumbous part), tenminal block and outlet valve etc.A storage battery is generally combined by 3 single lattice (6V battery) or 6 single lattice (12V battery).Each single lattice are by some positive plates and some negative plates (negative plate a slice more than positive plate), and interval overlapping forms, and centre superfine glass fibre partition board is isolated.Several pieces positive plate lead alloys weld together composition positive pole group, and several pieces negative plate lead alloys weld together composition negative pole group equally, and positive and negative electrode group is loaded on compositing monomer storage battery in battery case.Connect together with cascade from the battery case dividing plate top (or perforation through-wall welding) between single lattice with plumbous part or connection strap between cell.Cell through lid sealer bonds.The single lattice of head and the tail make leading out terminal, draw both positive and negative polarity.
Need to use bolt in the process that the storage battery of electric vehicle is installed in car load factory.Bolt: mechanical parts, the cylindrical threaded fastening piece of adapted nut.By head and screw rod (with an externally threaded cylindrical body) class fastening piece dimerous, need and nut screw connection, for being fastenedly connected two parts with through hole.Bolt is in daily life is worked as and in the middle of industrial production manufacture, and can't do without, bolt is also referred to as the rice of industry.
Bolt can be equipped with packing ring in use usually, as plain cushion, bullet pad etc.The effect of plain cushion is: (1) adds the area of contact of king bolt and machine; (2) spring pad is eliminated when unloading screw to the infringement of machine surface.The effect of bullet pad is: after fastening nut, and bullet pad, to nut elastic force, pushes against the frictional force between nut increase nuts and bolt, makes its difficult drop-off.
The design that usual plain cushion, bullet pad, bolt three are separated, when installing to car load, plain cushion, bullet pad must penetrate on bolt before installing by operator, then push down bolt, connecting line with pneumatic wrench, are connected by battery.Install in the process connected often there is plain cushion, phenomenon that bullet pad comes off, easily cause battery bolt looseness in the process used, add the internal resistance of battery terminal joint, internal resistance increases temperature also along with increase, finally easily cause battery catches fire, there is potential safety hazard.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of integration bolt, bolt, plain cushion integrated setting, plain cushion can not depart from bolt, in use, greatly facilitate the operation of operator, can prevent from use causing security incident because of bolt looseness simultaneously.
For achieving the above object, the utility model provides following technological scheme:
A kind of integration bolt, comprise bolt, the plain cushion be set on bolt, described bolt comprises the bolt head connected successively, threadless polished rod section, threaded thread section, the external diameter of polished rod section is less than the large footpath of thread section, described plain cushion is set in polished rod section, and the internal diameter of plain cushion is less than the large footpath of thread section.
The plain cushion of integration bolt of the present utility model is set in polished rod section, and the internal diameter of plain cushion is less than the large footpath of thread section, therefore, plain cushion can not depart from bolt, the two integrated setting, in use, the operation of easy-to-operat personnel greatly, and in use, bolt not easily loosens, and avoids and causes security incident because of bolt looseness.
In order to ensure that plain cushion can not depart from bolt, also ensure that plain cushion can be free to slide in polished rod section, as preferably, the ratio of the external diameter of the large footpath of described thread section, the internal diameter of plain cushion, polished rod section is 1: 0.85 ~ 0.95: 0.7 ~ 0.8 simultaneously.
Preferred further, the ratio of the external diameter of the large footpath of described thread section, the internal diameter of plain cushion, polished rod section is 1: 0.9: 0.8.
After fastening nut, bullet pad can give nut elastic force, pushes against the frictional force between nut increase nuts and bolt, make nut difficult drop-off, increase the Security of bolt, therefore integration bolt of the present utility model, as preferably, between described plain cushion and bolt head, be also arranged with bullet pad.
As preferably, the total thickness of described plain cushion, bullet pad and the length ratio of polished rod section are 0.5 ~ 0.8: 1.
Preferred further, the total thickness of described plain cushion, bullet pad and the length ratio of polished rod section are 0.5: 1.
Compared with prior art, the beneficial effects of the utility model are:
The plain cushion of integration bolt of the present utility model is set in polished rod section, and the internal diameter of plain cushion is less than the large footpath of thread section, therefore, plain cushion can not depart from bolt, the two integrated setting, in use, the operation of easy-to-operat personnel greatly, and in use, bolt not easily loosens, and avoids and causes security incident because of bolt looseness.
