Abstract

The utility model provides a folding lock for a steering wheel in an automobile. A lockset is arranged on a hollow lock rod. A clamping lever which is plugged with the hollow lock rod is composed of a locking section with a locking annular groove and a stop section which is pivoted with the end of the locking section. The lock rod and one end of the clamping lever are respectively provided with hooks which are arranged oppositely and are supported and clamped with the wheel edge of the steering wheel. When the utility model is locked, the two pivoting sections of the clamping lever are just inserted and covered in the hollow lock rod. So the clamping lever is in the state of a straight bar when the utility model is locked. When the lock for a steering wheel is not used, the clamping lever can move in the hollow lock rod and leads the hooks to disengage out of the steering wheel. Now, because of the movement of the clamping lever, the pivoting part is exposed, so the lock for a steering wheel can be folded to one side of the lock rod.

Description

Folding lock for stearing wheel

The utility model relates to a kind of lockset, particularly a kind of foldable automobile steering lock.

Present automobile steering lock is varied, but no matter the sort of version, all be with hollow locking bar with locking bar mutually the flexible supporting rod of plug-in mounting constitute, an end of locking bar and flexible supporting rod be provided with can with the bearing circle two respective disc edge places crotch of grab mutually, between locking bar and the flexible supporting rod in it, be provided with lockset, though this class lockset has certain lock function, the shortcoming of its existence also is conspicuous.Promptly because it is one to insert the elongated body of rod of string mutually, no matter when folding and unfolding, still in use all to occupy bigger space, inconvenience is carried and is deposited.In addition, flexible supporting rod can rotate in the locking bar endoporus, easily bumps when fetching.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, takes up space for a short time and provide a kind of, is difficult for the foldable automobile steering lock of idle running.

The purpose of this utility model is to realize by following technical scheme.

On the hollow locking bar, be provided with lockset, with the hollow locking bar mutually the supporting rod of plug-in mounting be to constitute for two sections by the lock segments of deciding annular groove with lock with sheathing section that the lock segments end is articulated, what one end of locking bar and supporting rod respectively was provided with opposing setting supports the crotch of card mutually with bearing circle dish edge, when locking, two sections of supporting rod articulate lucky the inserting of section and cover in the hollow locking bar, so be the straight-bar state during supporting rod locking, when time spent not, supporting rod can be scurried in the hollow locking bar and be moved and make crotch deviate from bearing circle, at this moment, because scurrying of supporting rod moved, its articulated section is outer dewiness, so collapsible to locking bar one side.

Therefore remarkable result of the present utility model is:

The 1st: because supporting rod is two sections articulated structures, covers in locking bar and make lockset be direct rod shape so can insert when locking, and collapsible after the release, be beneficial to deposit and carry.

The 2nd: the mutual bearing fit of guide finger on guide groove on the lock segments of supporting rod and the hollow locking bar, not only can play the effect that limits the axial excess in displacement of supporting rod, and, can prevent the circumferential rotation of supporting rod.

Concrete structure of the present utility model is realized by the following examples and accompanying drawing thereof.

Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model.

Fig. 2 is the structural perspective after the combination of the present utility model.

Fig. 3 is the section of structure after the combination of the present utility model.

Fig. 4 is the structural perspective of the utility model when folding.

Below in conjunction with accompanying drawing 1-4 concrete structure of the present utility model is described in detail:

The utility model has a hollow locking bar 3 that lockset 31 is installed, one end of hollow locking bar 3 has a crotch 32, with hollow locking bar 3 mutually plug-in mounting be one to have the supporting rod 4 that locks annular groove 12, one end of supporting rod 4 have one with the crotch 11 of crotch 32 opposing openings, it is characterized in that: supporting rod 4 be by lock segments 1 be connected to form with the movable mutually sheathing section 2 that is articulated of lock segments 1, crotch 11 is arranged on an end of lock segments 1.Referring to Fig. 1 to Fig. 4.

Structure of the present utility model also is:

The back segment of the locking annular groove 12 of lock segments 1 has a U-shaped clamp groove 13, the articulated slab 5 that inserts in the U-shaped clamp groove 13 is articulated in the clip slot 13 by bearing pin 132 activities, the other end of articulated slab 5 inserts in the U-shaped clamp groove 22 of sheathing section 2 front ends and by bearing pin 222 activities and articulates, offer an axial channel 14 vertically in the segment length between the front portion of the locking annular groove 12 of lock segments 1 and crotch 11, sliding with axial channel 14, what insert is the pilot pins of inwardly visiting in hollow locking bar 3 leading portions week 33.Referring to Fig. 1 to Fig. 4.

The articulated slab 5 that connects lock segments 1 and sheathing section 2 is a square bar shaped plate, two outer sections of plate offer the pin-and-hole 51 that installs with

bearing pin

132 and 222 activities, and bearing

132 and 222 is inserted build-in mutually with corresponding

pin shaft hole

131 and 221 about

U-lag

13 and 22 respectively and decided.Referring to Fig. 1 and Fig. 2.

The protecting of sheathing section 2 is arranged with a location collar 23 before holding cover 21.Referring to Fig. 1 and Fig. 2.

Using method of the present utility model is as follows:

During locking, supporting rod 4 is pushed away to hollow locking bar 3 interpolations.Referring to Fig. 2, treat two

crotches

32 and 11 and bearing circle dish edge fork support well after, lockset 31 is locked, even the annular groove 12 of the lock segments of the interior spy dead bolt of lockset 31 and supporting rod 4 blocks, sheathing section 2 then passes along hollow locking bar 3 and is overhanging state state to play the purpose that prevents that bearing circle is rotated, referring to Fig. 3.When locking, the pivot joint section of lock segments and sheathing section 2 is positioned at hollow locking bar 3, so whole supporting rod 4 is the straight-bar state.

And after the release, supporting rod 4 can axially back and forth be scurried along hollow locking bar 3 and be moved, and articulated slab 5 parts referring to Fig. 2, can fold when withdrawing from the hollow locking bar 3, as shown in Figure 4, because whole lock body contraction in length is deposited so be easy to carry.

The effect one of axial channel 14 is the excess in displacement plaies that limit supporting rod 4, the 2nd, prevent any rotation of supporting rod 4 in the hollow locking bar.
