Description
Technical field
The utility model belongs to a kind of machinery equipment part apparatus structure, especially a kind of fixedly round pin constructional device of axle head, and the axle head that is mainly used in the bearing pin of various vehicles is fixed.
Background technique
Bearing pin is component commonly used in various device or the mechanical device, is mainly used in the connection between the component, is generally " T " word shape.Generally be that the small end of " T " word shape bearing pin is inserted in the pin-and-hole of connecting device during use, the part of stretching out outside the pin-and-hole at the bearing pin small end is fixed bearing pin with a fixing device again, in case the bearing pin slippage.The means of fixation of the axle head fixing device of present bearing pin has a lot, can adopt cotter pin to fix, this is the fixing method the most commonly used of axle head of general bearing pin, this method is when using bearing pin, earlier bearing pin is inserted in the pin-and-hole of required connected element, stretch out part outside the pin-and-hole by inserting with cotter pin in the cotter pin pin-and-hole on the bearing pin end at the bearing pin small end then, move the afterbody of cotter pin again and fix, prevent that bearing pin from coming off.Use spring collar fixing in addition in addition, the method is directly to have draw-in groove on the bearing pin small end stretches out part outside the pin-and-hole, spring collar is stuck in the slippage that prevents bearing pin in the draw-in groove.Also have direct employing nut to fix bearing pin, this method is to process screw thread on the bearing pin small end stretches out part outside the pin-and-hole, with nut the axle head of bearing pin is fixed, in case the slippage of bearing pin.The main feature of the axle head fixation method of these bearing pins is, fixing very simple, and dismantle very convenient, bearing pin can be reused, but it is just not really suitable (as the appliance arrangement on the vehicle in the industrial and mineral place that can also dismantle easily after the installation that this method is not wished for some, in order to prevent that other people from stealing, after not wishing that bearing pin is installed, can disassemble easily).
(patent No. is 200620025160.2 to Chinese patent literature, denomination of invention is " rail truck is locked with round pin ") disclose a kind of rail truck that is used for railway and locked with round pin, it is characterized in that being made up of tapered end, jump ring chamber, clip spring seat and jump ring, tapered end comprises head, locking bar, locked groove and lock point; The jump ring chamber comprises pilot hole, jump ring chamber body, clip spring seat hole and seat limit, hole, and clip spring seat is embedded in the clip spring seat hole to be lived by checkpost, seat hole; Jump ring is installed in the body of jump ring chamber, and tapered end enters the jump ring chamber by the lock point by pilot hole and inserts jump ring, and jump ring snaps in the locked groove locking.Can not release behind this kind round pin locking lock, though can prevent effectively that like this vehicle fitting is stolen, banned simultaneously round pin has been welded dead anti-theft measure, but this structure is too inflexible, in case hindering for some reason, equipment needs maintenance, need that then round pin lock is carried out destructive beaing and break the round pin lock and just can unblank, so just probably injure bearing pin or its connected element, so necessary this is improved.
The model utility content
The purpose of this utility model is: at the deficiency of the axle head fixation method that has bearing pin now, exploitation one cover prevents the arbitrarily axle head round pin of dismounting, and this round pin just cannot arbitrarily disassemble later at the axle head that overlaps upper pin again.If dismounting must use special instrument to dismantle.
The purpose of this utility model is achieved through the following technical solutions: a kind of axle head round pin of bearing pin, comprise bearing pin and axle head round pin, described bearing pin is stepped bearing pin, the stepped portion of bearing pin is divided into the block of bearing pin one end, it is characterized in that: described axle head round pin is the fixing device of the bearing pin the other end, the axle head round pin is a fabricated structure, and the axle head round pin is fixing by the elastic fixing device that is installed in the bearing pin axle center, for preventing arbitrarily to dismantle composite structure axle head round pin; Described axle head round pin is the parts that cannot arbitrarily dismantle after being installed on the bearing pin, if dismounting must use special instrument to dismantle.Describedly prevent that arbitrarily dismantling composite structure axle head round pin is: in the pin-and-hole of the axle head of bearing pin knockdown axle head round pin is installed, the axle head round pin is fixed by the elastic locking device that is installed in the bearing pin, and can open under the effect of special tool.The axle head round pin can be divided into first round pin and second round pin.Be provided with elastic locking device between first round pin and second round pin, elastic locking device is the elasticity sliding motion mechanism that can slide in the axle center circular hole of the axle head of bearing pin, elastic locking device is installed in the axle center circular hole of axle head of bearing pin, the axle center circular hole inner bottom part of axle head is provided with spring, spring withstands an elastic collar, elastic collar is inserted in the slide block of band pin-and-hole and a keyhole and can moves under the drive of slide block or rotate, between the pin hole of the axle head of the axial end of bearing pin and bearing pin, have be used to open or the locking pin hole in the lockhole of elastic locking device, key by special use can be opened elastic locking device in lockhole, be used for the fixing axle head round pin of bearing pin axle head thereby open.The axle head round pin also can have only one side of something, and the pin-and-hole of the axle head of bearing pin also has only on one side at this moment, is blind hole.
Method of work of the present utility model is: after bearing pin is installed, earlier elastic locking device is placed in the pin hole of axle head of bearing pin, and then first round pin and second round pin be enclosed within respectively in the bearing pin pin hole, after allowing elastic locking device block first round pin and second round pin, form a kind of axle head round pin of the bearing pin that can not arbitrarily dismantle.
Advantage of the present utility model is: the axle head of bearing pin has adopted the end enclosure structure of sealing, and since this moment end socket be adjacent to the parts that bearing pin connected fully, after installing, can not disassemble again, also can not withdraw from bearing pin by directly beat bearing pin habitually in the past, avoid dismantling the phenomenon of equipment with regard to having reached like this, prevent by unloading the safeguard of bearing pin dismounting equipment thereby strengthened by the dismounting bearing pin.
