Description

Lock for preventing moisture and mud in rain

The utility model relates to the manufacturing of iron bag padlock.

Existing iron bag padlock is owing to be non-sealing, so only be fit to indoor use.The padlock shell of being particular about, lock core are all done but can not be used for for a long time in the rain outdoor with copper, more can not be used in the occasion of the many mud of many dusts.

The purpose of this utility model is to provide the iron pad lock in the rain that is applicable to occasions such as various humidities, water pouring, many dust, many mud.

The purpose of this utility model is achieved in that at first the method for taking " displacement " moves on to central authorities to the pellet shot from a slingshot in a row of inside, lock housing right side, spring displacement for 90 °, thereby the central authorities of lock housing just are strip because of thickening projection.At this moment inside, lock housing right side has not had " internal organ ", just opens a semicircle breach on the lock housing herein;

Second step was adopted the method for " isolation ": and the movable patchhole of lock ring (locking is used) is made the through hole of isolating fully with lock body inside, and the lower end in this hole communicates with aforementioned half round cut, unblocked in order to the draining spoil disposal, such weak spot has just been solved;

Second weak spot is the lock ring installing hole, take the method for " sealing " to solve: promptly earlier at (on the lock housing) one section short tube of lock ring installing hole fixed outside, establishing step (being that major diameter connects minor diameter) on the lock ring above herein again, load onto bucker, cover liner rubber sheet gasket, bucker is placed in the short tube periphery, and rubber sheet gasket is with the sealing of short tube mouth, and its pressure comes the step on the self-locking ring.Rubber sheet gasket, tarpaulin rise with lock ring when unblanking, but tarpaulin and short tube entangle all the time and do not break away from, this be because their height greater than the stroke of lock ring, so can be in the unlikely immersion of the rainwater of unblanking in the rain.

Last weak spot is the lock core hole towards the below, takes to solve with the method for sealing cap sealing: promptly there is internal thread at the lock core hole hole, with the sealing cap screw-in of a termination band external screw thread and sealing ring lock core hole is tightly sealed.For sealing cap is lost with easy to use, with brace, packing ring, screw sealing cap system is fixed on the lock housing, sealing cap can rotation and and revolution.

Because this lock does not rely on and does not use copper material more, so the cost increase is limited and effect than also good with copper.This lock is compared its tangible characteristics with existing padlock: be that this lock is fully closed, it is not afraid of humidity, drenches with rain, is not afraid of dust, mud.It is applicable to that the chemical plant that includes acid and alkali corrosion gas is interior among the adverse circumstances of outdoor round-the-clock and many dust mud.

More than be first scheme (lock core hole is towards the below) of this lock, describe it in the lump in an embodiment in detail after still having second scheme (lock core hole is towards the right side) to treat.Two embodiments of this lock have all been made sample, and through soaking, inflating test, the result is at all air tight, not bubbling and once successful, prove reasonable in design, suitable industrial living

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

Fig. 1: the outward appearance and the partial sectional view that are moistureproof anti-mud rain lock (first scheme)

Fig. 2: the vertical view that is Fig. 1

Fig. 3: the outward appearance and the partial sectional view that are moistureproof anti-mud rain lock (alternative plan)

Describe implementation detail in detail below in conjunction with Fig. 1-3:

This lock is made up of lock housing (9), lock core (7) and lock ring (0).Be characterized in: inner pellet shot from a slingshot, the spring in a row in lock housing right side all is displaced to the positive central authorities of lock housing, lock housing (9) central authorities are strip (8) because of the thickening projection, the movable through hole (1) that inserts of the lock ring (0) of top, lock housing right side, isolate fully with lock body inside, but communicate with the semicircle breach (2) on lock housing (9) right side.

At the upper left lock ring installing hole of lock housing hole, if be fixed in the upper left side that short tube (10) on the lock housing (9) protrudes from lock housing, establish step (13) at the left-hand side of lock ring (0), and suit, fixedly bucker (11) covers short tube (10), rubber sheet gasket (12) is arranged, with the tightly sealing of short tube (10) mouth in the bucker.

Lock core (7) and hole be towards the below, lock core and slightly inside indentation, and there is internal thread at the hole, screws in a termination band external screw thread and the sealing cap (5) that is with sealing ring (6) to seal.There is cannelure at the sealing cap middle part, and sealing ring (6) promptly is embedded in the groove, and sealing cap (5) is to fix on the lock housing (9) with brace (4) and packing ring, screw (3), and sealing cap (5) can rotation and revolution.

Second its composition of scheme of this lock is identical with the former, but lock core (22) hole is (pellet shot from a slingshot, spring are in the lock housing lower inner part) on the lock housing right side, the encapsulating method of its lock core hole is also identical with alternative plan, it is exactly slightly indentation of lock core (22), there is internal thread at the hole, screwing in sealing with the sealing cap that has external screw thread and sealing ring (19) (18), is to fix on the lock housing (23) with brace (20) packing ring and screw (21), and sealing cap (18) can rotation and revolution.

This programme and preceding difference are that the movable patchhole of right lock ring (15) is non through hole (16), and bottom it transverse row water hole (17) are arranged, and two Kong Douyu lock body internal insulation.

At the upper left lock ring of lock housing (23) (15) aperture is installed and establishes the short tube (24) that is fixed on the lock housing, between the space of short tube and lock ring (15), establish the sealing ring (25) that is normally off, and sealing ring (25) is embedded in the cannelure of lock ring (15), slides up and down with lock ring (15) in short tube.The height of self-evident short tube (24) must be greater than the stroke of lock ring.

This a kind of encapsulating method, because sealing ring is closed state all the time, thus can remove bucker from, can be at open and close in the rain, rainwater and dust can not immerse.
