Description

Three cassette locksets

Technical field

The utility model relates to a kind of locking device that is used to connect special-shaped pole stock.

Background technique

Existing lockset generally is made up of lock housing, lock wheel and reed with bayonet, for example Chinese patent CN87206373U discloses a kind of like this structure, the reed major part places in the lock housing, the lock housing top has opening, lock wheel is installed in interior and leans with the bending section of reed tail end, by the rotation lock wheel, makes bending section be subjected to active force, carry out the longitudinal extension campaign thereby drive the relative lock housing of whole reed, lock special-shaped pole stock.Because bending section is stressed bigger, so easily produce distortion and " allow " backward, make lock wheel and bending section slippage, locking lost efficacy promptly lock unreliable.The structure that also has a kind of reed tail end to be bent into 180 ° in the prior art, though this structure afterbody rigidity increase to some extent, more because of its bending, make the manufacturing process complexity, and easily crack, easily rupture in the use, shortened life of product.

Summary of the invention

The purpose of this utility model is to provide a kind of reliable lock, and the reed manufacturing process is simple, the three cassette locksets that the life-span is long.

In order to achieve the above object, the utility model is by the following technical solutions: a kind of three cassette locksets, have lock housing, lock wheel and reed with bayonet, lock housing is made hollow rectangular, the lock housing top has opening, in the lock wheel is installed in, there are three crotches as bayonet socket the front portion of reed, two crotch back-flexings each other on a middle crotch and both sides, reed is installed in the centre of lock housing, carry out the longitudinal extension campaign, the boss that the reed afterbody has an eccentric wheel of taking turns with lock to lean by lock wheel drive reed.

After adopting said structure, because the boss that the reed afterbody has an eccentric wheel of taking turns with lock to lean, this boss adopts impact briquetting, rigidity is big, and is stressed not yielding, thereby can slippage when leaning with the eccentric wheel of lock wheel, the longitudinal extension campaign of reed accurately puts in place, thereby makes reliable lock; Because this boss can disposable impact briquetting, not resembling 180 ° of bendings needs repeatedly moulding, thereby manufacturing process is simple again, and the distortion of punching press simultaneously is little, is difficult for cracking, and makes the life of product prolongation.

Embodiment

The embodiment who provides below in conjunction with accompanying drawing is described in further detail the utility model.

As shown in Figure 1, 2, 3, three cassette locksets of the present utility model, have lock housing 7, lock wheel 2 and reed with bayonet 5, lock housing 7 is made hollow rectangular, lock housing 7 tops have opening 4, in lock wheel 2 is installed in, the front portion of reed 5 have three

crotches

6,6 as bayonet socket ', a middle crotch 6 ' with two crotch 6 back-flexings each other on both sides, reed 5 is installed in the centre of lock housing 7, drive reed 5 by lock wheel 2 and carry out the longitudinal extension campaign, reed 5 afterbodys have a boss 1 that leans with the eccentric wheel 3 of locking wheel 2.

Shown in Fig. 4,5,6, the balance slotted eye 8 that it is 6～14mm that the upper bend section 13 of the intermediate plate tongue 11 of reed 5 has a length that communicates with the punching press cavity 9 of supporting leg 10 makes that to be formed with a balancing segment on the upper bend section 13 of intermediate plate tongue 11 also be the balance groove hole section.The purpose of setting up this balance slotted eye 8 is for the elasticity that makes intermediate plate tongue 11 and biside plate tongue 12 balance more, thus the reseting performance that improves locking and unclamp.The width of this balance slotted eye 8 can be 1.4～2.5mm, accomplishes that preferably balancing segment with the upper bend section 13 of intermediate plate tongue 11 also is that the cross-section area of balance groove hole section equates with the cross-section area sum of biside plate tongue 12 corresponding sites.

Shown in Fig. 4,5,6,7,8, boss 1 the right is wide and high, and the left side is gradually little and gradually short, and such boss 1 rigidity is big.Tear reed 5 when preventing punching press boss 1, reed 5 convex platforms 1 front end place has chap preventing process hole 14.Boss 1 of the present utility model is except can being structures such as welding boss for the punching press boss.

As shown in Figure 9, among another embodiment of the present utility model, upper bend section 13 its both sides of the intermediate plate tongue 11 of reed 5 all have balance gap 15, and the cross-sectional width of the balance gap section of upper bend section 13 is 4～6mm, makes that to be formed with a balancing segment on the upper bend section 13 of intermediate plate tongue 11 also be balance gap section.The balancing segment of preferably accomplishing the upper bend section 13 of intermediate plate tongue 11 also is that the cross-section area of balance gap section equates with the cross-section area sum of biside plate tongue 12 corresponding sites.All the other structures are identical with above-mentioned first embodiment.Set up the purpose of balance gap 15, with above-mentioned to set up the purpose of balance slotted eye 8 be identical.

When the utility model uses, as shown in Figure 1, 2, 3, rotation lock wheel 2, be resisted against 3 drive reeds 5 of eccentric wheel on the boss 1 to left movement on the lock wheel 2, because the ramp effect on the lock housing 7, make three crotches 6,6 ' strut up and down respectively, as shown in fig. 1, middle crotch 6 ' move downward, the crotch 6 of both sides moves upward, thereby pins special-shaped pole stock 16.During release, only need counterrotating lock wheel 2, reed 5 is moved right, three crotches 6,6 ' under the elastic force effect, draw in point-blank, as shown in Figure 2, crotch 6,6 ' all can be thrown off special-shaped pole stock 16.
