Description

Locking bolt has the plate anti-theft lock of vehicle-repairing function

The present invention relates to the plate anti-theft lock that a kind of locking bolt has maintenance ordinary bicycle, mountain bike, motorcycle, power assist vehicle spanner, screwdriver function.

Ordinary bicycle, mountain bike, motorcycle, power assist vehicle generally use slotting rod formula lock of U type and D type lock to pin two breeches pipes that support rear wheel at present, to stop wheel.Its major defect is:

1.U the type locking bolt is to make with the cylindricality metal material, locking bolt itself is cut off by " locking pliers " easily.

2. the chimeric surface of detent on the locking bolt and dead bolt is very little, and locking bolt or lock body are adopted violent meanses such as turning round, twist, prize, pound, causes the distortion of dead bolt and locking bolt detent force part to be thrown off.

Recent years, bicycle, motorcycle, power assist vehicle are stolen in a large number, and except that the social security reason, the Vehicle lock structure quality problems directly provide chance and possibility for spreading of stealing vehicle behavior.Therefore improve the safe antitheft performance of lock and will make positive contribution social safety is stable.I have applied for patent of invention (publication number CN 1139172A) by the multi-purpose plate theft-proof lock of invention, and obtain utility model patent (ZL 95.214324.0).This patent has overcome the shortcoming of above-mentioned lock, and the cylindricality locking bolt that it at first inserts the U type rod formula lock changes plate shape locking bolt into, and board-like locking bolt can be resisted the destruction of " locking pliers " fully.

Its principle is: " locking pliers " is according to shouldering rod principle after prolonging pliers grip length, extremely strong extruding force is applied on two points of cylinder locking bolt plane of structure diameter correspondence, the cutting edge extruding of " V " type acute angle of " locking pliers " is cut on the section of being cut object, under the vertical cut-out power effect that the cutting edge acute side produces towards the lateral force of outer generation and cutting edge axial line, along with closing up of pincers cutting edge, cut off component and also become big gradually, finally force the stress point metal cylinder to produce " V " type depression and brittle failure.Because " locking pliers " adopts pincers handle and gear force-increasing mechanism, general 950 millimeters alligator pliers handles are when hand is removed power 30kg; Can produce the cut-out power of 9-15 ton at jaw.The metal wire rods such as round steel, tool steel and steel wire of φ 20-25 millimeter can be sheared disconnected like a cork.

" but locking pliers " can not shear the sheet metal of certain width and thickness, and this is because " locking pliers " is different with the tinman's snips operating principle of shearing thin metal blank.During the work of the cutting edge up and down of scissors not on same plane, close up in the process it as chopper at handle, cutting edge is to being cut the constantly staggered cutting of object up and down, the continuous opening and closing of handle, the formed angle of cutting edge is non-vanishing all the time up and down for scissors, and the vertex position at angle is constantly displacement forward along with the opening and closing of handle.And " locking pliers " up and down the central axis of cutting edge close up in the process all the time at grade at handle, its cutting edge is up and down only produced extruding force as clip to cutting object, the process opening and closing for once of handle of operation, the angle that forms relatively until cutting edge up and down are zero to stop.320 millimeters the tinman's snips that shear ability is stronger on the market can only be sheared the sheet metal below 0.75 millimeter, and gruelling, and scissors is just powerless when steel plate thickness reaches 1 millimeter.

On mechanics, tension stress is far longer than shear stress.Because the part that " locking pliers " contacts with metal sheet no longer is two points, but two lines.When power that jaw applies metal sheet was dispersed on these two lines, " locking pliers " can't overcome the extremely powerful tension stress that sheet metal extends and had, and therefore can't cut off the locking bolt of plate shape metal material as " locking pliers " of clip.

Same U template formula locking bolt is not only on the minimum face of dead bolt embedding locking bolt inboard groove with the lock mode of dead bolt, enters lock body behind the dead bolt through hole of lock bolt plate face and locks in the lock tongue cavity groove of bolt throughhole one sidewall but dead bolt is run through.After dead bolt pinned locking bolt, any violence that manually applies also can't destroy the lock function of dead bolt, unless dead bolt is fractureed in lock body.Other design features of above-mentioned patent are used for the lock field with the plate anti-theft lock principle in addition, will inevitably succeed.

Since ordinary bicycle, mountain bike, motorcycle, power assist vehicle came out, lock was exactly its primary driver's tool, often also is unique driver's tool.These vehicles also should dispose a cover vehicle-mounted maintenance instrument in fact.When vehicle ', the emergency processing effectively of pitching of accidental part.Various trials of carrying car repair tool with car were at home and abroad once arranged, small tools bag of snapping on car beam pipe for example, or on saddle tube, install kit (case) additional, put car repair tools such as various spanners and screwdriver at kit bag and kit (case) lining.

But these measures are not all popularized, and its reason is:

1. the car repair tool in the driver's tool bag (case) is when the car owner locks car and leaves away, lose easily stolen, if car owner's taking-up instrument is carried extremely inconvenient after locking car at every turn.

2. various in style with the car repair outfit, car travel when jolting instrument mutually collision make a noise, a kind of burdensome sensation is arranged.

3. the chance of car repair tool utilization and few is purchased these instruments and need be paid a considerable spending, so the car owner does not carry car repair tool with car mostly.

Because lack with the car repair outfit, glitch can lead to major break down, and the existence of glitch finally also can increase maintenance cost in the future, in the long run, reduces the bulk life time of vehicle possibly.

Its technical characterictic of the present invention has covered above-mentioned scope of patent protection fully; and the design feature of utilizing U template shape locking bolt is on this basis left the hole or the opening of all hex nuts of the above vehicle of at least a model, track wrench size on each position of plate face; leave the hook spanner of bicycle head slotted round nut; leave the wrench opening of rung bar nut, and attachment sleeve spanner and die nut.Be processed into a word spiral shell cutter and a Phillips screwdriver of lozenges at the tail end of open spanner mouth.Hole, opening and the adhering tool of all size that is provided with according to different automobile types so just can be formed the dismantling device of various types of vehicles.The function that lock is had concurrently pull wrench, screwdriver.This lock has been not only for the car owner has brought convenience, and is difficult for stolen.

Main purpose of the present invention is, a kind of firm theftproof lock of the lock car function integration that repairs is provided.Locking bolt and lock body that this lock is finished vehicle-repairing function cooperatively interact.

During the lock car, the locking bolt of vehicle-repairing function is by secure lock, and car repair tool, lock body, car become one, and are difficult for stolen.

During garage, locking bolt inserts the locking bolt locating hole on the lock body, does not produce noise, does not have burdensome sense.

When repairing, locking bolt is extracted out from the locking bolt hole of lock body, uses arbitrarily.

Opening or the hole of designing spanner, screwdriver on the plate face of U-shape lock bolt two arms only prolong the board-like locking bolt two arm lengths 5-7cm of simple function lock, and its locking bolt anti-destructive function is not affected.After the manufacturing process of locking bolt increased, the manufacturing cost of lock had also only increased about two to three one-tenth, and the expense that is increased only is to purchase five to 1/7th of these car repair tool expenses.

Task of the present invention realizes by following design scheme:

A kind of multipurpose lock comprises the lock body of core with lock, and the fixing fixed head of lock body inserts the lock body bolt throughhole of locking and finish the hole and the opening of car repair tool function with the plate face of the U template formula locking bolt of lower part in addition except having the dead bolt through hole of finishing lock function.Be on the center line of two arm plate faces of " ∪ " type or " ∏ " type in the locking bolt vertical section, insert during its locking and respectively have the dead bolt through hole that two or more and dead bolt shape are complementary and spacing is arranged on the lock body part.Wherein, the dead bolt through hole that has can the double as hexagonal or tetragonal nut pull the hole.When locking, can freely adjust spacing according to the different automobile types breeches pipe between circular arc and the lock body in the locking bolt U type like this.Multi-form size openings and the hole of reasonable disposition on the peripheral panels face of each group dead bolt through hole, its quantity and shape meet all interior hexagonal holes of the above bicycle of at least a model, mountain bike, motorcycle, power assist vehicle, square hole, notch and the hook spanner be made up of gib head and interior circular arc and rung bar spanner and a word, Phillips screwdriver.The requirement according to institute's force arm all can be attached with six square bolts outside the dismounting secretly, the box spanner of nut connection and the die nut of SOC.HD. cap screw on the outer plate surface of circular arc in the U-shape lock bolt.In ordinary bicycle U-shape lock bolt, have the mouth of pulling that only lacks a rung bar cap on the plate face of circular arc.Its lock body feature: have two groups of locking bolt positioning through hole that are complementary with U template formula locking bolt cross section on the square shape lock body, two groups of locking bolt positioning through hole are vertical mutually, connect mutually.One group of horizontal locking bolt positioning through hole is finished lock function, and another is organized vertical locking bolt positioning through hole and finish locking bolt placement function when lock is opened.Since the front end proper extension of locking bolt upper lock tongue through hole the plate face in combination wrench opening and hole, when entering, locking bolt have the lock bolt plate face of 5-7cm can pass across lock body approximately when horizontal locking bolt positioning through hole is finished blocking function, for fear of when locking locking bolt to extend in two formed small spaces of end face of lock body part operation key operated, so the design of the central axis of core hole and locking bolt through hole is certain angle, make keyhole be positioned at oblique upper, the anterior lock core hole face of lock body is still vertical mutually with the lock body top surface.Locking bolt does not disturb mutually with the key direction of insertion when locking like this, and the keyhole that the while opens for fear of direction obliquely is subjected to soaking of sleet, and direction is provided with eaves before the screening water of level above the keyhole inclined-plane, with the normal running of protection key keyhole.
