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 fixing device of bearing pin, comprise bearing pin and axle head fixing device, described bearing pin is stepped bearing pin, the stepped enlarged head of bearing pin is divided into the block of bearing pin one end, it is characterized in that: described axle head fixing device is the fixing device of the bearing pin the other end, for preventing random disassembly-type axle head fixing device; Described axle head fixing device 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 random disassembly-type axle head fixing device from being the head type axle head fixing device that a termination sealing is installed at the axle head of bearing pin, head type axle head fixing device comprises bearing pin part, end socket part and elastic locking device.The end socket of end socket part is that the end is the card cap of sealing, and the main body of the end of card cap and card cap is two body glued constructions, and the end of card cap is to connect as one by bonding main body with the card cap.The diaphragm of the end of card cap for backing down by special tool, the material of diaphragm is that plexiglass or hard plastics are made into; On the bearing pin of bearing pin part, have draw-in groove, in the end socket endoporus of end socket part, also have draw-in groove, the endoporus of end socket just in time matches with bearing pin, when end socket partly is enclosed within on the bearing pin, draw-in groove in the end socket endoporus is just in time corresponding with the draw-in groove on the bearing pin, be equipped with in draw-in groove in the end socket endoporus and the draw-in groove on the bearing pin and prevent that end socket breaks away from the elastic locking device of bearing pin, elastic locking device can be a kind of elastic collar, it also can be elastic circlip, elastic locking device can be mounted in when not being installed in bearing pin on the bearing pin part draw-in groove, also can be mounted in the end socket endoporus draw-in groove.
Method of work of the present utility model is: after bearing pin is installed, earlier elastic locking device is placed in the end socket endoporus of end socket part, or be placed on the bearing pin of bearing pin part on the draw-in groove, and then partly be enclosed within end socket on the bearing pin, the draw-in groove for the treatment of the end socket endoporus with on draw-in groove on the bearing pin is corresponding mutually after, elastic locking device will block end socket automatically, and form a kind of axle head fixing device 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 arbitrarily 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 random dismounting bearing pin.
