Description

Direct insertion lock

The utility model relates to lock.

China Patent No. provides a kind of Tubular padlock for the utility model patent of " ZL93240736.6 ".It comprises a cylinder lock housing, a button pipe, a spring, two latches, a cover cyclization, a flexible member, a locating snap ring, a torque spring, fit lid, a sliding pin, a core, a dead bolt, a closing cap and a lock bolt rod etc.This patent is compared with its listed prior art, has following advantage: 1, during snap close, lock bolt rod can insert in the cylinder lock housing simultaneously, operate more convenient, 2, during snap close, can not must open with key, lock bolt rod directly can be inserted in the cylinder lock housing, and can be automatically with the lock bolt rod snap close.But it also has following deficiency, and for example component are more, and complex structure is difficult for thereby make, and cost is high.

It is the same that the purpose of this utility model provides a kind of and above-mentioned patent, when not only having snap close, the lock bolt rod two ends can be inserted in the cylinder lock housing simultaneously, and also can open with key, lock bolt rod directly can be inserted into the lock of same advantage in the cylinder lock housing, and it to go back component few, structure is simpler.

The said lock of the utility model is such.Comparing identical with correlation technique is that it also comprises: an inverted U-shaped lock bolt rod; One hollow cylinder lock housing, suitable distance has two locking bolt holes on this cylinder lock housing; One capping; The core of one bar with lock; Different with correlation technique is, it also comprises a hollow tumbler that is the semicircle tubular, and on this tumbler, its middle part is extended with one section link plate, the certain distance in link plate both sides is last, also respectively is extended with on the tumbler on the end of a guide plate, said tumbler and also has a hole; Two cylindrical bars; One spring; One hollow pipe; Block tongue with two shapes; The said inverted U-shaped relative side in its two ends of lock bolt rod respectively has a bayonet socket; Hollow pipe be contained in the hollow tumbler that is the semicircle tubular and with this tumbler on the link plate that stretches out be fixed together; Spring is arranged on the centre in the hollow pipe; Two cylindrical bars are separately positioned on the two ends in the hollow pipe; Two block tongues are separately positioned on two guide plates that stretch out on the tumbler, and they can move along the hollow axis that is semicircle tubular tumbler along guide plate, said these two block tongues respectively be contained in that the cylindrical bar at two ends is fixedly linked in the hollow circular-tube; Hollow cylinder lock housing one end seals with capping, its other end pack into the successively hollow tumbler that is the semicircle tubular, core; The locking bar of core is inserted in the hole of tumbler one end; Fixing between core and the hollow cylinder lock housing, under the drive of core locking bar, the hollow tumbler that is the semicircle tubular can rotate in the cylinder lock housing.

During the snap close lock bolt rod, the two ends of lock bolt rod can be pressed in the locking bolt hole on the cylinder lock housing simultaneously, at this moment the block tongue in two locking bolt holes overcomes the elastic force of spring simultaneously to intrinsic displacement by cylindrical bar under the extruding of locking bolt rod end, when block tongue runs into bayonet socket on the lock bolt rod, under the effect of spring, block tongue returns in the bayonet socket that is stuck in lock bolt rod, so, can open and automatically lock bolt rod latched in the cylinder lock housing without key.When unblanking, rotate key, at this moment the locking bar of core drives the hollow tumbler rotation that is the semicircle tubular, and at this moment block tongue produces the bayonet socket at release lock tightening latch two ends thereupon, and lock just has been unlocked.

The lockset that the utility model provides has following advantage:

1, the same with correlation technique, the lock bolt rod two ends of locking can be inserted in the cylinder lock housing simultaneously, and can open with key,

2, because its component are few, thereby structure is simpler, manufactures easily, and cost is also cheap.

Be described in further detail this usefulness is novel in fact below in conjunction with accompanying drawing.

Fig. 1 is a three-dimensional exploded view of the present utility model,

Fig. 2 is the overall structure schematic diagram after the utility model assembling,

Fig. 3, Fig. 4 be respectively the utility model partial sectional view, it illustrated lock bolt rod in the cylinder lock housing by snap close with the state when triping.

With reference to Fig. 1, the utility model comprises: an inverted U-shaped lock bolt rod 1 (turn of bilge of lock bolt rod 1 does not draw in the figure), and the relative side in two ends of said inverted U-shaped lock bolt rod 1 respectively has a bayonet socket 11 and 12; One hollow cylinder lock housing 2, suitable distance has two locking bolt holes 21 and 22 on this cylinder lock housing 2; The core 3 of one bar 31 with lock; The one hollow tumbler that is the semicircle tubular 4, its middle part is extended with one section link plate 41 on this tumbler 4, also respectively be extended with a guide plate 42 and 43 on, the tumbler 4 last, also have a hole 44 on the end of said this tumbler 4 apart from the distance that link plate 41 both sides are certain; Two cylindrical bars 51 and 52; One spring 6; The block tongue 81 and 82 of one hollow 7 two shapes of pipe; With a capping 9.Please also refer to Fig. 2, during assembling: a hollow pipe 7 be contained in the hollow tumbler that is the semicircle tubular 4 and with tumbler 4 on the link plate 41 that stretches out be fixedly linked; Spring 6 is arranged on the centre in the hollow pipe 7; Two cylindrical bars 51 and 52 are separately positioned on the two ends in the hollow pipe 7; Two block tongues 81 and 82 are separately positioned on two guide plates that stretch out 42 and 43 on the tumbler 4, and they can move along the hollow axis that is semicircle tubular tumbler 4 along guide plate 42 and 43; Said two block tongues 81 and 82 are fixedly linked with the cylindrical bar 51 and 52 that is contained in two ends in the hollow circular-tube 7 again respectively; Hollow cylinder lock housing 2 one ends are with capping 9 sealing, and from the other end pack into successively hollow tumbler that is the semicircle tubular 4 and core 3, the locking bar 31 of core 3 is inserted in the hole 44 of tumbler 4 one ends; Core 3 is fixed between hollow cylinder lock housing 2, as adopting pin 10 fixing; Under the drive of core locking bar 31, the hollow tumbler that is the semicircle tubular 4 can rotate in cylinder lock housing 2.

During the snap close lock bolt rod, the two ends of lock bolt rod can be pressed in the locking bolt hole on the cylinder lock housing simultaneously, at this moment two block tongues in the locking bolt hole are pushed, overcome the elastic force of spring simultaneously to intrinsic displacement by cylindrical bar respectively by the two ends of lock bolt rod, after bayonet socket on the lock bolt rod puts in place, under the effect of spring, block tongue returns in the bayonet socket that is stuck on the lock bolt rod, and lock bolt rod is just by on the snap close, as shown in Figure 3.When unblanking, rotate key, at this moment the locking bar on the core drives the hollow tumbler rotation that is the semicircle tubular, and at this moment block tongue also rotates behind the bayonet socket place that is produced release lock tightening latch two ends thereupon, and lock just has been unlocked, as shown in Figure 4.
