Description

Latch for bicycle lock

Lock is indispensable to the people who has car in daily life, and group is savage because of auto theft, causes to purchase car and must purchase a lock separately.Therefore, along with increasing substantially of car quantity, lock also has many innovations and improvement.Early stage lock is divided into lock body and U-shaped latch hook two parts, after unblanking, look for an appropriate location to place this lock, also is a headachy problem.Thus, the lock on the car front-wheel shock-absorbing bar occurred being fixed in,, reached purpose sealed or this lock of keeping by the U-shaped latch hook is inserted in the lock body, not only easy to use, also save simultaneously and seek the worry of placing this lock.

Though can be fixed in the lock on the car front-wheel shock-absorbing bar, solve the difficulty of carrying; See also shown in Figure 6ly, it is the outside drawing of general bayonet lock, only is provided with the unidirectional arc of leading, and has only when the parallel insertion lock body of U-shaped latch hook, is just slipped into smoothly, makes bayonet lock can buckle in the short slot of U-shaped latch hook; But if after opening this lock the U-shaped latch hook taken out, when vertically inserting lock body, must with key operated treat that system is moved back bayonet lock after, the U-shaped latch hook could insert smoothly, causes the inconvenience in the use.The utility model provides a kind of compound mitre and two-way vertical bayonet lock, no matter during the perpendicular or parallel insertion lock body of U-shaped latch hook, neitherly must move back bayonet lock by key system, get final product smooth ejection bayonet lock, bayonet lock is buckled in the short slot of U-shaped latch hook, reach the U-shaped latch hook and combine, reach the purpose of locking wheel or this lock of keeping with lock body.

Main purpose of the present utility model is to provide a kind of bayonet lock of lock, no matter make the U-shaped latch hook parallel or when vertically inserting lock body, the ejection bayonet lock makes bayonet lock be detained the short slot of solid U-shaped latch hook all smoothly.

Technical solution of the present utility model is: a kind of bayonet lock of lock, the one end is provided with fixture block, one side is provided with pressing plate, pressing plate the place ahead is provided with embedded hole, and be provided with the U-shaped breach at the pressing plate appropriate location, it can embed in the embedding slot of lock body, make fixture block be positioned at the intersection of storing hole and lockhole, wherein, the top of fixture block and side all are provided with the inclined-plane, no matter when making the U-shaped latch hook from vertical insertion storage hole, lock body top or parallel insertion lockhole, the ejection bayonet lock buckles in the suitable short slot of U-shaped latch hook all smoothly.

In order more clearly to understand architectural feature of the present utility model and effect, attached now as follows with description of drawings:

Fig. 7 is that of the present utility model another implemented illustration.

See also Figure 1 and Figure 2, can be fixed in the lock on the car front-wheel shock-absorbing bar, mainly comprise lock body (1) and iron hoop (3) and U-shaped latch hook (4) three parts, wherein lock body (1) is the block of inner hollow, it is provided with the two storage holes (11) of vertically running through lock body (1) up and down in addition, and front and back are provided with the two parallel lockholes (12) that run through lock body (1), and be provided with an embedding slot (13) in a side of lock body (1), and the place ahead of lock body (1) forms half arc end (14), after can be fixedly embedded a control lock body (2), its place ahead is provided with backing pin (21).

Bayonet lock (5) one ends form fixture block (51), fixture block (51) top and side form the inclined-plane, all the other two vertical, bayonet lock (5) one sides are provided with pressing plate (52), its appropriate location is provided with U-shaped breach (53), and be provided with embedded hole (55) in pressing plate (52) the place ahead and can put into a spring (54), a pair of bayonet lock (5) is oppositely put into embedding slot (13), seal the opening of embedding slot (13) again, make the fixture block (51) of bayonet lock (5) be positioned at the intersection of storing hole and lockhole, the backing pin (21) in control lock body (2) the place ahead is embedded in the U-shaped breach (53) of two bayonet locks (5), transmission by backing pin (21) can make two bayonet locks (5) produce compression or uphold, and this is that lock utilizes the compression of bayonet lock (5) or extension and the mode that locks.

Iron hoop (3) is the lamellar body that central authorities become the semicircle arcuation; have the lockhole (12) of breach (31) to avoid stopping lock body (1) at the circular arc two ends; adopt two screws (33) lock body (1) and iron hoop (3) can be fixed on the columniform shock-absorbing bar of car front-wheel; rubber pad (32) is positioned at iron hoop (3) inboard; the shock-absorbing bar that can adapt to different thicknesses is with anti-loose (except preventing to get loose to absorbing vibration and protect the equal tool effect of this shock-absorbing bar), and U-shaped latch hook (4) inboard is provided with short slot (41).

See also shown in Figure 3, it is the sectional view of the lockhole (12) in the parallel insertion lock body of U-shaped latch hook (4) (1), because of being provided with the inclined-plane in bayonet lock (5) two ends fixture blocks (51) side, make U-shaped latch hook (4) smoothly ejection bayonet lock (5) to the required short slot (41), but desire is extracted U-shaped latch hook (4) out, because of fixture block (51) bottom and slope-less but vertical, need dial to change to extract out after control lock body (2) makes backing pin (21) stir bayonet lock (5) with key; That is U-shaped latch hook (4) is by the inclined-plane on the fixture block (51), and ejection bayonet lock (5) buckles in the short slot 41 of its top, and can't directly make the short slot (41) below bayonet lock (5) returning; In like manner, see also shown in Figure 4ly, it vertically inserts the sectional view in the storage hole (11) of lock body top for U-shaped latch hook (4).Because of the top of fixture block (51) also is provided with the inclined-plane, just U-shaped latch hook (4) also smoothly ejection bayonet lock (5) it is buckled in the suitable short slot (41).

See also shown in Figure 5, no matter parallel insertion lockhole of U-shaped latch hook (4) (12) or vertical the insertion are stored in the hole (11), neitherly must control lock body (2) by key turns and can embed smoothly, and when desiring directly extraction U-shaped latch hook (4), no matter it is perpendicular or parallel in lock body (1), fixture block (51) bottom becomes a plane with short slot (41) below, so can't directly take out.

Square U-shaped latch hook among the embodiment among Fig. 2 also can adopt circular U-shaped latch hook, and corresponding square lockhole and storage Kong Yike change round keyhole into and store the hole, as shown in Figure 7.

The general lock of the utility model has more the effect part and is that this lock has compound mitre and two-way vertical bayonet lock, no matter during the perpendicular or parallel insertion lock body of U-shaped latch hook, neitherly must move back bayonet lock by key system, get final product smooth ejection bayonet lock, bayonet lock is buckled in the short slot of U-shaped latch hook, reach the U-shaped latch hook and be combined with lock body, and then reach the purpose of locking wheel or this lock of keeping.
