Abstract
The utility model discloses a bonding bolt which comprises a bolt head and a screw. The top, connected with the bolt head, of the screw is a neck portion, the neck portion is provided with an annular stopper with a chip scraping structure, the chip scraping structure is arranged on the lower bottom face of the annular stopper, the screw is axially provided with a chip discharge groove penetrating through the bottom end of the screw, outer threads on the screw form a discontinuous thread structure through the chip discharge groove, the screw is provided with a concave portion, outer threads of the concave portion are trapezoid threads or sawtooth-shaped threads, and the chip discharge groove is communicated with the concave portion. The bonding bolt solves the problems that the chip discharge function of a bonding bolt is not sufficient, and the chip scraping function is poor, and factors causing the poor bonding phenomenon are effectively eliminated. The bonding bolt has the advantage of being popularized and used in the automobile manufacturing industry.
Description
Technical field
The utility model relates to bolt field, especially relates to a kind of for the bonding bolt in automobile.
Background technique
On automobile, need to apply the place of bonding bolt, if adopt plain bolt, cannot effectively remove paint and oxide layer on vehicle body, and the bonding bolt generally using is at present because chip removal is insufficient, can affect installation quality, and the phenomenon of bad earth occurs.
Notification number is CN202867499U, the day for announcing is to disclose a kind of bonding bolt in the patent document on April 10th, 2013, comprise head and screwed screw rod, the sawtooth that the bonding face of described lower head is provided with some annular spread, paints for striking off surface, described screw rod tail end is provided with at least one axial slot scraping.Screw rod tail end in this structure is provided with slot scraping, although to a certain extent for scraping paint or oxide layer, the chip removal effect of screw rod body is not strong, will have influence on the installation effect of bonding.
Notification number is CN102364131A, date of publication is to disclose a kind of bonding bolt in the patent document on February 29th, 2012, comprise head and screw part, the middle part of described screw part is provided with depressed part, and the part that the surface configuration of described depressed part is cylndrical surface is also provided with the screw thread consistent with the thread rotary orientation of screw part main body.Although this structure can to a certain degree play the effect of scraping bits by depressed part is set, with dregs guiding groove be communicated with chip discharging structure describe not detailed, chip removal function is perfect not.And bolt head does not possess the effect of scraping bits, in function, be short of to some extent.
Model utility content
The purpose of this utility model is that to solve bonding bolt chip removal effect insufficient and have the problem of scraping the functional difference of bits concurrently, aims to provide one and optimizes structure, practical reliable, is beneficial to the bonding bolt popularizing.
The utility model is to make by the following technical programs object be achieved.
A kind of bonding bolt, comprise bolt head and screw rod, the top of the screw rod being connected with bolt head is bar neck, bar neck is provided with band scrapes the annular stop of bits structure, scrapes bits structure and is arranged on the bottom surface of annular stop, axially offers the groove that connects screw rod bottom on screw rod, outside thread on screw rod forms interrupted screw-thread structure by groove, on screw rod, be provided with depressed part, the outside thread of depressed part is trapezoidal thread or buttress thread form, and groove is connected with depressed part.The annular stop of scraping bits structure by band has solved the paint of attachment face and the problem of striking off of oxide layer.Coordinate the scrap of wiping off is got rid of timely with groove by the depressed part arranging on screw rod.Effectively eliminate the factor that bad earth phenomenon occurs.
As preferably, annular stop and the screw rod structure that is formed in one.Also can annular stop be set to stop washer.Integrated formed structure is simple and easy to make.Be arranged to stop washer, convenient mounting or dismounting are changed, and flexibility is good.
As the improvement of above technological scheme, can preferably be arranged to some sawtooth of the bottom surface of annular stop by scraping bits structure.The setting of described sawtooth is preferably two kinds of technological schemes:
1. described in, sawtooth is uniformly distributed in the form of a ring.
2. described in, sawtooth is monodentate line or the arrangement of bidentate line.
As preferably, the bottom land of groove and the shaft axis of screw rod tilt setting, and the degree of depth of groove is deepened gradually towards the bottom of screw rod.The groove of deepening is gradually conducive to get rid of timely scrap.
As preferably, groove is provided with two to four, evenly arranges along the circumferential surface of screw rod, and depressed part is corresponding setting one by one with groove.Multiple grooves and depressed part are evenly set and can effectively strengthen scraping the effect of bits and chip removal.
The beneficial effects of the utility model: delicate structure practicality, good reliability.Effectively eliminate the factor that bad earth phenomenon occurs.Be of value to penetration and promotion application in auto manufacturing.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-bolt head, 2-screw rod, 3-groove, 4-depressed part, 5-annular stop.
Embodiment
Also by reference to the accompanying drawings the utility model is described in detail below by embodiment.
As shown in the structural representation of a kind of bonding bolt of Fig. 1 the utility model, comprise bolt head 1 and screw rod 2, the top of the screw rod 2 being connected with bolt head 1 is bar neck, bar neck is provided with band and scrapes the annular stop 5 of considering structure to be worth doing, scrape the bottom surface that bits structure is arranged on annular stop 5, on screw rod 2, axially offer the groove 3 that connects screw rod 2 bottoms, outside thread on screw rod 2 forms interrupted screw-thread structure by groove 3, on screw rod 2, be provided with depressed part 4, the outside thread of depressed part 4 is set to trapezoidal thread, also can be set to buttress thread form, groove 3 is connected with depressed part 4.
The preferred implementation of annular stop 5, can be set to integrated formed structure by annular stop 5 and screw rod 2.In order to install and remove conveniently, also annular stop 5 can be set to stop washer.
Scrape some sawtooth that bits structure can preferably be set to the bottom surface of annular stop 5.Sawtooth can preferably arrange equally distributed in the form of a ring structure.Or be preferably set to the arranging structure of monodentate line or bidentate line.
The preferred implementation of groove 3, tilts setting by the shaft axis of the bottom land of groove 3 and screw rod 2, and the degree of depth of groove 3 is deepened gradually towards the bottom of screw rod 2.
