Abstract
The invention provides a waterproof thread fastener, comprised of welding bolt and nut, where the welding bolt has bolt head and threaded bolt bar, the bolt head is equipped with circular welding salient side, when welding with parts through the circular welding salient side, the whole salient side can fuse and closely joint with the parts to form a circle of closed seal belt and the nut has threaded inner hole cooperating with the bolt, the threaded inner hole is designed into a structure with top end open and bottom end closed and also designed into a big-end-up sink hole and cooperates with the bolt, and the upper part of the threaded inner hole is relatively big so as to form liquid storage space between the inner wall of the nut and the bolt bar, thus able to guide the leakage liquid to the storage space for storage and prevent water and dust and other impurities passing through the inner hole into the parts. And it has functions of linking and fixing, water-proofing and dust-proofing, and features of simple structure, connecting reliability, strong bearing capacity and saving materials.
Description
Technical field
The present invention relates to a kind of threaded fastener.
Background technique
Common threaded fastener is constituted by screw bolt and nut, wherein bolt has two kinds of penetrability and non-penetratives, traditional penetrability bolt only possesses it fastening fundamental function is installed, because the narrow limitation of its structure, when bolt and installation position welding were fitted, bolt faying surface and installation position can not fit tightly.This is because its face of weld is usually designed to three boss, with 120 degree serves as to stagger mutually at interval, when welding with body parts, by bonding after the boss fusion with car body spare, but can leave comparatively significantly space between the welding rear boss, external substance comprises that water and dust penetrate into the screw rod side of penetrability bolt by these slits, flows along the screw rod direction, therefore can not play waterproof action.In addition, owing to disconnect between three boss, discontinuity has reduced welding reliability; It is limited to connect area, also influences its bearing capacity.And its nut is non-water-tight substantially, is six prisms or four prism type on the structure, and central authorities have through hole, after the part assembling, can leave certain fit up gap between them, external substance comprises that water and dust can flow into by the slit between the screw thread, flow in the part from the through hole lower end.
Such threaded fastener is for the fastening part of needs, and is very unfavorable as the sealing and the waterproof of automobile engine compartment, car steering storehouse and storage room, can not satisfy requirements such as existing machinery product high sealing, high strength.
Summary of the invention
The objective of the invention is to the deficiency that traditional threaded fastener exists, design a kind of water-proof screw-thread fastening piece, have waterproof and dust reduction capability, and can improve welding reliability, improve bearing capacity etc.
Technological scheme of the present invention is as follows:
A kind of water-proof screw-thread fastening piece, form by weld bolt and nut, weld bolt has bolt head and threaded shank bar, circular welding chimb is arranged on the bolt head, when by circular welding chimb and part welding, whole chimb can both weld fusion, fits tightly with part to be connected like this, form the sealing strip of a circle sealing, can stop the infiltration of liquid substances such as water and the propagation of noise.And circular welding chimb is stressed evenly, connects more reliably, connects the area increase, has improved its bearing capacity, can guarantee the molded effect of welding heat preferably.And nut is six prisms or four prism type, has endoporus, and bore design is the structure of upper end open lower end closed, can prevent that like this impurity such as sealing, dust flow in the part by endoporus.Both are in conjunction with the sealability that just can significantly improve part.
Further, for impurity such as the water that prevents to flow to endoporus, dust overflow from the nut head owing to do not descend fluid space, the present invention becomes the little counterbore in bottom with bore design, cooperate with bolt, top is designed greatlyyer, between nut inner wall and bolt shank, to form the storage liquid space, the liquid that leaks out can be drained into this space also stores, prevent that effectively liquid is from the nut side leakage, realize reliable waterproof and dustproof purpose, and its position approaches the nut oral area, also is beneficial to natural air drying.
In addition, adapt to part mounting hole with different sizes in order both to make things convenient for nut, simplify the structure of nut head again, save material, form a circle shirt rim at the cold pier of nut head, the flange plate or the packing ring that are used for alternative conventional nut head combine with Assembly part.
In order to reach reasonable connection effect, also can be with the Cross section Design equilateral triangle of circular welding chimb, the easier welding heat of this chimb than other shapes such as rectangles is molded.In addition, the height that welds chimb is designed to 1mm, is designed to 2mm, can reach the preferable molded effect of welding heat apart from the outer peripheral distance of bolt head.
As seen this threaded fastener has not only possessed the connection fixation of regular screw threads fastening pieces by the improvement design to screw bolt and nut, also possesses the effect of waterproof and dustproof, and is simple in structure, connects reliably, and bearing capacity is strong, and materials are saved.
The present invention can extensively use at mechanical industry fit on, be specially adapted to the not high component of component and local strength of sealing requirements, in being connected as assembling in automobile engine compartment, car steering storehouse and storage room etc., can play and improve the engine operation environment and prolong the motor effect in working life, solve the seepy question of cockpit, storage room, improve occupant's travelling comfort, certain help is also arranged for the auto sound noise reduction.

Fig. 2 is the structural representation of weld bolt wherein.
Fig. 3 is the amplification profile of bolt head part.
Fig. 4 is the structural representation of nut.
Embodiment
Referring to Fig. 1, this threaded fastener is made up of weld bolt 1 and nut 2.
In conjunction with Fig. 2 and Fig. 3 as seen, weld bolt 1 has bolt head 11 and threaded shank bar 12, and a circular welding chimb 13 is arranged on bolt head 11, and the cross section of this welding chimb is an equilateral triangle, highly is 1mm, and is outer peripheral apart from 2mm apart from bolt head.When by 3 welding of circular welding chimb and part, can fit tightly with part 3 and be connected, form the sealing strip of a circle sealing, stop the infiltration of liquid substances such as water and the propagation of noise, thereby improve the sealability of part.
In conjunction with Fig. 4 as seen, nut 2 its profiles are hexagon, has endoporus in it, endoporus is the structure of upper end open lower end closed, the bottom is divided into and cooperates counterbore 23, top to be divided into a storage liquid space 22 with bolt, makes impurity such as water can be deposited on this part space between nut inner wall and the bolt, the cold pier of nut head is formed with a circle shirt rim 21, combines with Assembly part during assembling.
