The improvement of the utility model is that the tail ends of the telescopic rod and the lock handle are totally provided with grips. The handle mouth point of lock handle is provided with a retraction mouth. A directional telescopic mechanism is formed when the telescopic rod is inserted into the lock handle, and the buckle on the telescopic rod is just retracted the retraction mouth of the lock handle after the telescopic rod is inserted into the lock handle. The utility model has the advantages of convenient use, directional telescoping, small volume, and low cost.

Description

Concealed lock for motor vehicle steering wheel

The utility model belongs to lock, particularly about the automobile steering lock of automobile burglar.

General commercially available handle lock, with the double-joint type stretching structure, the fastener that combines usefulness with steering wheel has multiple variations such as U-shaped, Y shape, hand button shape, spirality, pursue purpose and the ability that fastens separately, but do not make improvements for whether the volume of lock itself, length, operation be convenient, cause general being seen vehicle steering to be latched in following shortcoming.

1. shank of the key wears into the flexible design of double-joint type each other with expansion link, but fastener on the expansion link and the omnidirectional mechanism of the fastener on the shank of the key, can rotate arbitrarily, must rotate expansion link earlier when therefore taking, make fastener and the ability of the fastener homonymy on shank of the key padlock steering wheel on the expansion link, use inconvenience to some extent.

2. the expansion link fastener of the flexible design of double-joint type is positioned at the front end of expansion link, can't hide in the shank of the key fully during expansion link retraction shank of the key, thereby its length and volume is obviously small and exquisite not as single-unit formula structure lock.

3. the expansion link of the flexible design of general double-joint type can freely rotate arbitrarily, and the scrobicular ring ditch that all utilizes the expansion link body of rod to make is realized so the lock of the lockset between shank of the key and expansion link is pulled, and the processing time consuming of scrobicular ring ditch is bothersome, the cost height, and effect there is no part easy to use.

For this reason, the purpose of this utility model provides a kind of Tibetan and goes into formula expansion link and shank of the key double-joint type automobile steering lock, when expansion link inserts lock, has directed telescoping mechanism, and the length of length after the insertion and single-unit formula lock is suitable, and cost is low, and is easy to use.

The utility model also is a double-joint type, expansion link and shank of the key two parts by equal bracelet tool are formed, be characterized in: said shank of the key is for constituting the hollow tube of handle, at a side of the fastener mouth of shrinking back in addition, lock body and locking bolt are positioned at fastener and shrink back the offside of mouth, said expansion link also has locating hole, lock pull hole and handle, lock the offside that the hole of pulling is positioned at fastener, the size and dimension of the hollow tube internal diameter of the profile of expansion link and size and shank of the key adapts, when expansion link inserts shank of the key, directed flexible, owing to be provided with the mouth of shrinking back, after the insertion, the length of lock and single-unit formula are phase-locked to be worked as.

The hollow tube of said shank of the key is for having the body of any cross sectional shape.

The present in conjunction with the embodiments accompanying drawing the utility model is elaborated.

Fig. 1 is embodiment 1, and promptly the shank of the key hollow tube is that the formula automobile steering lock is gone in the Tibetan of square tube.

Fig. 2 is the sectional drawing of Fig. 1.

Fig. 3 is the expanded view of Fig. 1.

Fig. 4 is embodiment 2, and promptly the shank of the key hollow tube is that the formula automobile steering lock is gone in the Tibetan of pipe.

Fig. 5 is the sectional drawing of Fig. 4.

Fig. 6 is the expanded view of Fig. 4.

1 describe at first in conjunction with the embodiments, by Fig. 2 and Fig. 3 as seen, shank of the key 1 body tail end is a handle 14, one side has fastener 11, this fastener 11 can be U-shaped, Y shape, hand button shape or any button that fastens steering wheel of executing, the homonymy that shank of the key 1 front end handle mouth is positioned at fastener 11 offers the mouth 12 of shrinking back, fastener 21 for expansion link 2 inserts, and the offside of the shank of the key 1 and the mouth 12 of shrinking back is provided with lock body 13 and locking bolt 131, the tail end of expansion link 2 is a handle 23, the interior cross sectional shape and the size of the hollow tube of the outer cross sectional shape of expansion link and size and shank of the key 1 are complementary, and are all squarely, are convenient to insert, expansion link one side is fixed with a fastener 21, this fastener 21 can be U-shaped, Y shape, the any button that fastens on the steering wheel of executing of hand button shape or other, expansion link 2 are positioned at fastener 21 offside front ends has several to run through the lock hole 22 of pulling, and runs through lock for the locking bolt 131 of shank of the key 1 lock body 13 and pulls, expansion link 2 is positioned at fastener 21 offsides and is provided with one and runs through locating hole 221 near handbar, when time in the expansion link 2 withdrawal shank of the keys 1 is done the location and locks the usefulness of pulling.

From the above, the utility model as shown in Figure 1, have directed flexible, easy and simple to handle, deposit advantages such as volume is little.

Secondly, 2 describe in conjunction with the embodiments, by Fig. 4 to circular pipe type automobile steering lock shown in Figure 6 as can be known, the tail end of shank of the key 10 is a handle 105, the tail end of expansion link 20 is a handle 205, the mouth 102 of shrinking back of shank of the key 10 is same with the mouth 12 of shrinking back of shank of the key 1, the lock that runs through of locking pull hole 202 and expansion link 2 that runs through of expansion link 20 is pulled hole 22 together, and what run through locating hole 203 and expansion link 2 runs through locating hole 221 together, unique difference, Fig. 1 is a square tube, Fig. 4 is a pipe, so be equipped with a guiding ditch 204 on expansion link 20 bodies of rod, cooperates with it, shank of the key 10 inner tubal walls are established a dowel 104 at least, can be directed flexible when making circular pipe type expansion link 20 insert shank of the key 10.

In sum as can be known, the utility model is not only convenient to be used, and has characteristics such as volume is little, directed flexible low cost of manufacture, has reached the purpose of invention.
