Description

Folded steering wheel lock

Technical field

The utility model relates to a kind of folded steering wheel lock, and bearing circle spoke post, the folded steering wheel lock that makes the robber can't use the method for cut direction dish to unload are protected in particularly a kind of frontstall and armor front and back, back of utilizing.

Background technology

Present domestic great majority are used for the handle lock of automobile burglar, mainly contain flexible top dog formula, T-shaped folder formula, baseball rod-type and collapsible.Flexible top dog formula handle lock is to be welded with crotch on telescopic steel pole two ends, when telescopic steel pole extends, is locked on the bearing circle thereby the two ends crotch withstands the outer rim of bearing circle.Thereby the steel pole of elongation can push up and bump automotive interior and make bearing circle can't rotate the purpose that reaches automobile burglar.Two guard shields before and after handle lock one end of T-shaped folder formula has, two guard shields be locker on the outer rim of bearing circle, the top handle then withstands Auto Instrument desk can not rotate bearing circle.One end of baseball rod-type handle lock has locker or latch hook, shape is locked in like the steel pole of baseball bar on the outer rim of bearing circle bearing circle can not be rotated.The principle of work of collapsible and flexible top dog formula is similar, and two sections Metallic rod that respectively have a crotch are hinged; During use, two sections Metallic rod are opened, be locked on the bearing circle thereby two crotches withstand the outer rim of bearing circle, the Metallic rod of elongation can make bearing circle rotate.Cut for anti-saw is anti-, the general abundant heaviness of such handle lock makes the difficult way of cutting with saw of robber remove destruction direction dish lock.Yet, the bearing circle of being locked but not anti-saw anti-cutting, the especially outer rim of bearing circle, it is to be made by the very thin little metal tube of edge in the plastics.The robber only needs 20 or 30 seconds with one common hacksaw, just can cut one or two otch on the outer rim of bearing circle, and handle lock is taken out from the otch that cuts.If one only to delay the robber to anti-theft column lock short one minute, just and the robber need not any technology anti-theft column lock was lost efficacy, this anti-theft column lock can be described as no much antitheft effectiveness.

Safety cover type locker automobile (bearing circle) anti-theft column lock that Chinese patent ZL 200520058918-8 proposes; the key distinction of it and traditional burglarproof lock for steering wheel is that safety cover type locker of guarding against theft for cars can protect bearing circle effectively: its U-shaped guard shield is with the spoke post of bearing circle and near outer rim ladle cover and covering; be locked on the spoke post of bearing circle by lock fine strain of millet; make the robber cut off this spoke post and near outer rim with the saw shear method; therefore can't unload safety cover type locker of guarding against theft for cars, thereby solve the fatal shortcoming of handle lock: the method for cutting bearing circle with simple saw just can unload handle lock.But safety cover type locker of guarding against theft for cars is to utilize the top handle to withstand Auto Instrument desk bearing circle can not be rotated and to reach antitheft purpose.Yet the instrument carrier panel of some vehicle is not over against bearing circle, and perhaps instrument desk is too low, makes the top handle of safety cover type locker of guarding against theft for cars can not withstand Automobile instrument, thereby causes safety cover type locker of guarding against theft for cars not too to be suitable for this part vehicle.

Summary of the invention

The purpose of this utility model provides a kind of folded steering wheel lock; it not only can protect bearing circle spoke post; make the robber can't cut off this spoke post; therefore can't unload handle lock with the method that saw is cut bearing circle; greatly improved the theftproof performance of handle lock; and its locking bar must not withstand instrument desk, therefore can be suitable for more vehicle.

For realizing above-mentioned purpose, the utility model adopts following technical solution, promptly mainly is made up of frontstall, lock core body, back armor, turning cylinder, locking bar and head part.A pair of registration mast is arranged on the frontstall.Lock core is arranged, dead bolt and pass the turning cylinder of lock core body on the lock core body.The lock core body rigidity is connected on the frontstall, and lock core body is also passed in the rotating shaft of back armor, and back armor can be around shaft swing, so the relative position of it and frontstall can be and opens and clamping.Locking bar is being connected with the turning cylinder rigidity.When locking bar forwarded deployed position to, dead bolt inserted in the lock hole of turning cylinder under the spring force effect, turning cylinder can not be rotated, thereby make locking bar be locked in deployed position.And when locking bar during in deployed position, the head part of locking bar front end withstands the back armor, makes the back armor can only be in relative position with the frontstall clamping.

During collection, back armor is in the relative position with the frontstall clamping, and locking bar also is close to frontstall, makes the length overall of lock very short, and volume is also little.During use, open the back armor, folded steering wheel lock is placed on bearing circle, at this moment, a pair of registration mast forwards locking bar to deployed position then across the both sides of bearing circle spoke post, dead bolt is under the spring force effect, insert in the lock hole of turning cylinder, turning cylinder can not be rotated, thereby make locking bar be locked in deployed position.And when locking bar during in deployed position, the head part of locking bar front end withstands the back armor, clips bearing circle spoke post before and after making frontstall and back armor, and a pair of registration mast is across the both sides of bearing circle spoke post, thereby folded steering wheel lock is locked on the bearing circle firmly.Because open locking bar is longer, thereby makes bearing circle can't rotate the purpose that reaches automobile burglar in car.

The utility model has the advantages that:, therefore can't destroy the bearing circle at this place and take out folded steering wheel lock with saw or the method for cutting because frontstall and back are being protected the lock outer rim and the spoke post of bearing circle at place of folded steering wheel lock before and after the armor; Because a pair of registration mast is locked on this spoke post folded steering wheel lock across the both sides of bearing circle spoke post, make that other position of sawing or cutting bearing circle also can't removing direction dish lock.Thereby solved the fatal shortcoming of common handle lock: the method for cutting bearing circle with simple saw just can unload handle lock.Its locking bar must not withstand instrument desk, therefore can be suitable for more vehicle.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.But the utility model is not limited in following case study on implementation.

According to shown in Figure 1, the utility model mainly is made up of frontstall 1, a pair of registration mast 7, lock core body 2, back armor 3, turning cylinder 4, locking bar 5 and head part 6.Be connected with to rigidity registration mast 7 and lock core body 2 on the frontstall 1.In this embodiment, registration mast 7 is connected on the frontstall 1 to method rigidity such as riveted joint or bolted connection by welding.The turning cylinder 4 that passes lock core body 2 has connecting bore 8, and the joint pin 9 that is welded on the locking bar 5 penetrates in the connecting bore 8, with bolt or rivet joint pin 9 is fixed in turning cylinder 4 then.The preferably square or rectangle in the cross section of joint pin 9, correspondingly, connecting bore 8 also is square or rectangle.Locking bar 5 is steel pipes, and the front end of locking bar 5 is connecting head part 6.Locking bar 5 can rotate around the axle center of turning cylinder 4, locking bar 5 can be in amount to position or deployed position.One hinge 10 vertical with locking bar 5 arranged, and back armor 3 is connected on the hinge 10, and can be around hinge 10 swings, so the relative position of it and frontstall 1 can be and opens and clamping.In this embodiment, hinge 10 passes lock core body 2, but hinge 10 also can pass frontstall 1 or other parts.

Fig. 2 is a folded steering wheel lock that is unkitted locking bar 5, and not expressing locking bar 5 on figure can be from more clearly to show the relevant position of each parts.On Fig. 2, back armor 3 is in deployed position with frontstall 1.Fig. 3 has showed that then back armor 3 and frontstall 1 are in the clamping position.Adding locking bar 5 on Fig. 2 and Fig. 3, is exactly one basic folded steering wheel lock.Fig. 4 has showed one folded steering wheel lock, and armor 3 is in deployed position with frontstall 1 thereafter, and locking bar 5 is in and amounts to the position among the figure.Fig. 5 has showed one folded steering wheel lock, and armor 3 is in the clamping position with frontstall 1 thereafter, and locking bar 5 is in and amounts to the position among the figure.

Fig. 6 is the transparent view of lock core body 2.In this embodiment, lock core body 2 can be the die casting body of aluminium or zinc, or the die casting body of aluminium or zinc adds shell (not representing shell on the figure) and forms.Lock core 11 is arranged on the lock core body 2, dead bolt 12 and spring 14, turning cylinder 4 passes lock core body 2.Fig. 7 is the fundamental diagram of lock core body 2: rotation turning cylinder 4, when the dead bolt hole on the turning cylinder 4 13 during facing to dead bolt 12, dead bolt 12 can insert dead bolt hole 13 under spring 14 effects, turning cylinder 4 is stuck and can not rotates, thereby be in lock-out state.When inserting key rotation lock core 11, the driving lever 15 of lock core 11 tail ends is stirred dead bolt 12, and dead bolt 12 is withdrawed from from dead bolt hole 13, and turning cylinder 4 can rotate, thereby is in unlocking condition.

When locking bar 5 is opened, the turning cylinder 4 that is being connected with locking bar 5 just can rotate, dead bolt hole 13 on turning cylinder 4 faces dead bolt 12, dead bolt 12 inserts dead bolt hole 13 under spring 14 effects, turning cylinder 4 is stuck and can not rotates, thereby locking bar 5 can not be rotated and be locked in deployed position, as shown in Figure 8.At this moment, the head part 6 of locking bar 5 front ends withstands back armor 3, makes back armor 3 can only not be in the relative position with frontstall 1 clamping around shaft swing.

Fig. 9 to Figure 12 is that folded steering wheel lock is the scheme drawing that how to be locked on the bearing circle.In order can clearly to show, locking bar 5 does not draw on the figure.Fig. 9 and Figure 10 have showed when being locked on the bearing circle on folded steering wheel lock, earlier back armor 3 are opened, and a pair of registration mast 7 is faced toward the spoke post 17 of bearing circle, then folded steering wheel lock are placed on the bearing circle 16.Fig. 9 cuts open frontstall 1 part, therefore can clearly show the both sides of a pair of registration mast 7 across the spoke post 17 of bearing circle.Figure 10 has showed that the folded steering wheel lock that does not have locking bar 5 is placed on the situation on the bearing circle 16.Figure 11 and Figure 12 have showed that folded steering wheel lock is placed on the bearing circle 16, and back armor 3 is in the clamping position.Figure 11 cuts open frontstall 1 part, therefore can clearly a pair of registration mast 7 across the both sides of the spoke post 17 of bearing circle, Figure 11 and Figure 12 have showed that frontstall 1 and back armor 3 front and back clamp the spoke post 17 of bearing circle.

Figure 13 and Figure 14 have demonstrated one the process that is locked on the folded steering wheel lock on the bearing circle.Among Figure 13, earlier back armor 3 is opened, the spoke post 17 of a pair of registration mast 7 facing to bearing circle, then folded steering wheel lock is placed on the bearing circle 16, this hour locking lever 5 is in amounts to the position.At Figure 14, locking bar 5 is opened, until the click clatter there being one, this is the sound that dead bolt 12 produces when inserting dead bolt hole 13 under spring 14 effects, at this moment turning cylinder 4 is stuck and can not rotates, thereby locking bar 5 can not be rotated and is locked in deployed position.Simultaneously, armor 3 made it clamp bearing circle after the head part 6 of locking bar 5 front ends withstood.Because a pair of registration mast 7 is clamped spoke post 17 from left and right directions, frontstall 1 is clamped spoke post 17 with 3 front and back of armor, back, and folded steering wheel lock is locked on the bearing circle firmly.And open locking bar 5 has limited the rotation of bearing circle, thereby reaches the automobile burglar purpose.

During collection, back armor is in the relative position with frontstall 1 clamping, and locking bar also is close to frontstall 1, as shown in figure 15.Therefore the length overall of lock is very short, and volume is also little.

Because the thickness of the bearing circle spoke post 17 of various vehicles is all different, so frontstall 1 is also answered different frontstall 1 and back armor 3 front and back clamping direction dish spoke post 17 (referring to Figure 16 and Figure 17) of just making with the included angle B between the armor 3 of back.The included angle B of adjusting between frontstall 1 and the back armor 3 has two kinds of methods: the one, and the rotational angle A of increase or minimizing locking bar 5, big corner A can obtain little included angle B, and little corner A can obtain big included angle B; The 2nd, the distance L of increase or minimizing head part 6 and joint pin.Among Figure 16, short distance L obtains little included angle B; And in Figure 17, long distance L obtains big included angle B.In this embodiment, when locking bar 5 was locked, the dead bolt hole 13 that dead bolt 12 inserts on the turning cylinder 4 under spring 14 effects can not rotate locking bar 5, so locking bar 5 is when locked, and its rotational angle A is a unmodified, and a kind of method of the mat woven of fine bamboo strips is not suitable for this embodiment.In this embodiment, adopted two kinds of methods of the mat woven of fine bamboo strips to go to regulate included angle B between frontstall 1 and the back armor 3.

Figure 18 is the detail drawing of head part 6, and head part endoporus 18 is U-shapeds, and the head part front end has circular hole 19, and circular hole one side has one, and restriction screw 20 passes.

Figure 19 is the assembling exploded perspective scheme drawing of head part 6 assemblies; Figure 20 is the schematic perspective view of head part 6 assemblies, and Figure 21 is the generalized section of head part 6 assemblies.Head part 6 assemblies are regulated bolt 21 by head part 6, and captive nut 24 is formed with restriction screw 23.Regulating bolt 21 has a corner shoulder 22, and this have the bolt popular name of a corner shoulder cup square neck bolt.Regulate bolt 21 and penetrate, almost completely enter in the circular hole 19, only leave a bit every crack C until corner shoulder 22 from head part 6 front end circular holes 19.Captive nut 24 screws in regulates bolt 21, in the U-shaped endoporus 18 that enters into head part 6 fully, with special glue captive nut 24 is fixed on and regulates on the bolt 21.Have every crack C owing to regulate between bolt 21 and the head part 6, regulate bolt 21 and can in head part 6 front end circular holes 19, rotate, but can not separate with head part 6.Like this, when adjusting bolt 21 moves, will be with head part 6 to move.If screw in limiting screw 23, restriction screw 23 limits the corner shoulder 22 of regulating bolt 21, and adjusting bolt 21 no longer can be rotated.

Figure 22 is the assembling decomposing schematic representation of head part 6 assemblies and locking bar 5.It is to weld a block plate and form on the front end of locking bar 5 that the front end of locking bar 5 (near an end of joint pin 9) has a platform 25, this platform 25.The outline in this cross section, platform 25 place is a U-shaped, and is corresponding with U-shaped endoporus 18 cross sections of head part 6.Therefore, head part 6 can be inserted on the platform 25 of locking bar 5 front ends.Platform 25 can not rotate head part 6 around locking bar 5, can only move forward and backward along locking bar 5.Because locking bar 5 is steel pipes, setting nut 26 is welded in locking bar 5 front ends.Screw in or screw out setting nut 26 regulating bolt 21, will drive head part 6 assembly retractions or stretch out locking bar 5, thereby distance L is diminished or increase (referring to Figure 16 and Figure 17).When rotation adjusting bolt 21 and after obtaining suitable distance L, limiting the restriction screw 20 that screw 23 screws on the head parts 6, restriction screw 23 limits the corner of regulating bolt 21 and takes on 22, thereby adjusting bolt 21 no longer can be rotated distance L is no longer changed.6 assembly adjustable range L can only carry out when lock in the folded steering wheel lock end with head part.After folded steering wheel lock was locked, head part assembly 6 withstood back armor 3, referring to Figure 15 and Figure 17, because back armor 3 covers restriction screw 23, restriction screw 23 can't be screwed out, therefore can not adjustable range L.

When folded steering wheel lock was locked, a pair of registration mast 7 was positioned on this spoke post folded steering wheel lock across the both sides of the spoke post 17 of bearing circle.But the width size of the spoke post 17 of the bearing circle of every kind of vehicle differs greatly.If the width of the spoke post 17 of bearing circle is too big, 7 of registration masts can't be put into; If the width of the spoke post 17 of bearing circle is too little, the spacing between registration mast 7 and the spoke post 17 is too big, and is too loosening after folded steering wheel lock is locked.Be sort this problem out, the distance between a pair of registration mast 7 is answered scalable.Figure 23 is another kind of embodiment, and registration mast 7 tail ends are welded with nut seat 27, and 4 slotted holes 28 are arranged on the nut seat 27; An elliptical aperture 29 and an elongated slot 30 are arranged on the frontstall 1, row's bolt hole 31 is respectively arranged on elongated slot 30 both sides.Registration mast 7 passes 4 slotted holes 28 on the nut seat 27 that elongated slot 30,4 support bolts pass bolt hole 31 on the both sides and registration mast 7, screws with nut 33 then, thereby registration mast 7 is fixed on the frontstall 1.

Another registration mast 7 passes elliptical aperture 29, and similarly, 4 support bolts 34 pass 4 slotted holes 28 on the nut seat 27 that 4 bolts hole 31 and registration mast 7 are arranged on elliptical aperture 29 peripheries, screw with nut 33 then, and registration mast 7 just is fixed on the frontstall 1 like this.

Because registration mast 7 can be fixed on any positions in the elongated slot 30, the distance of it and another registration mast 7 is with regard to scalable so.Regulate registration mast 7 apart from the time, 4 support bolts 34 are unscrewed, registration mast 7 is moved to the position of required separation distance, bolt 34 is screwed then can again.

Because many people can cover direction indicators cover on the bearing circle 16, bearing circle outer rim size is increased.Therefore, elliptical aperture 29 allows registration masts 7 adjusting positions, makes the distance of registration mast 7 and frontstall 1 bending edge 32 increase or reduces, to adapt to the bearing circle that is covered with or does not have direction indicators cover.
