Description

Cylinder-type lock

The present invention relates to a kind of cylinder-type lock, refer in particular to a kind of inside and outside flat handle that has, internal construction is improved, is suitable for the cylindrical door lock that the disabled person uses.

Traditional door is used the horn lock, is the horn shape handle confession gripping rotation with circle, therefore, is known as the horn lock again.But, this kind loudspeaker handle can't use for the disabled person, therefore, this loudspeaker handle portion preferably replaces with flat handle, yet this flat handle is being pressed on time, need bigger pressure, therefore, whole lockset just need be improved, otherwise the problem damaging and can't reset of being easy to is arranged promptly, in addition, this case applicant has " tubular disability lock " patent the 8220361 No. eight in Taiwan application, be in, outer handle is combined in the door with bolt, the outside, in making, outer handle is rotatable, rotate the dead bolt of the lock bolt that is pulled with a square shaft, this outer handle has a rotation central siphon, in have an application cylinder to be driven with correct key by the core of outer handle, or rotate with the turn-button tube by internal handle, one interlock plate is with the square external diameter of square opening and an interlock ring separates or mesh, lock and to rotate so that flat handle is, maybe the opened the door situation that can become to rotate.

The purpose of this utility model is improved the structure of this cylinder-type lock, and it can be combined with flat handle, uses for the disabled person.

Cylinder-type lock of the present invention, its main body mainly is made of Internal handle, outer handle, this main body drives axle by one and combines with thimble in conjunction with after leading the device that contracts again, drive axle and can be nested with combination for Internal handle, and stretch out by the inner handle central shaft hole with a button, leading the device that contracts has a central siphon can supply outer handle combination, has two spring pushing tow slurcams that the hook arm-tie is resetted in the device that contracts but lead; Its characteristics are: Internal handle and outer handle are flat handle, this outer handle with axis hole for the core group hold into, and be inserted in the bossy body of a combination bore for the core group, the two has locating piece, establishes elastic projection by locating piece, can make the core group be easy to the taking-up replacing; Each holds to go into another inner spring bar to the two spring internal diameters that lead the device that contracts again, and this inner spring bar one end can withstand on slurcam or hook arm-tie, and end is stretched out by the wall that leads the device that contracts in addition, and with a plate apical grafting, plate with lead the device that contracts and be seated in the thimble jointly; Main body has an accessory plate in addition, accessory plate, is established screw with two pin in addition and is combined on the thimble for retaining element at the central siphon that leads the device that contracts with a borehole jack, and accessory plate can stretch out outside the circular hole of door with two arc limits in addition, there is the fixture block of protrusion on the arc limit, can snap in the hole, cave, location of a circular hole side.

Describe embodiments of the invention in detail below in conjunction with accompanying drawing.

Description of drawings:

Fig. 1 is a stereogram of the present invention.

Fig. 2 is the present invention's elevation from outer handle side when assembling.

Fig. 3 is the 3-3 sectional drawing of Fig. 2.

Fig. 4 is the 4-4 partial enlarged drawing of Fig. 3.

Fig. 5 is the 5-5 sectional drawing of Fig. 3.

Shown in first figure, lock of the present invention includes major parts such as main body 1, Internal handle 1, outer handle 3.

Main body 1 includes thimble 11, drives axle 12, leads contract a device 13 and a subsidy plate 14, thimble 11, drive axle 12, lead the device 13 that contracts and can be known structure, combining makes the button 121 that drives axle 12 be stretched out by the central shaft hole 20 of Internal handle 2, and the central siphons 131 that lead in the device 13 that contracts can supply outer handle 3 windings.This case is characterised in that the reposition element structure that leads in the device 13 that contracts, because Internal handle 2, outer handle 3 is flat handle, so, drive axle 12, the strength that resets of central siphon 131 needs bigger, therefore, if with 132 overstrikings of known back-moving spring or increase coefficient of elasticity, then certainly will cause the difficulty in the assembly, therefore, the present invention increases in addition back-moving spring 134 in two, known back-moving spring 132 1 ends withstand on slurcam 133, end withstands on the wall 130 that leads the device 13 that contracts in addition, 134 one-tenth of back-moving spring are than minor diameter in of the present invention in addition, can be enclosed within the internal diameter of back-moving spring 132, these two interior back-moving spring 134 1 ends are passed through by the hole 1331 of slurcam 133, and withstand on the baffle plate 1351 of clasp joint plate 135, maybe can be with hole 1331 sealings of slurcam 133, but make back-moving spring 134 1 end roof pressures, back-moving spring 134 end is in addition passed through by the hole 1301 of wall 130, and by 136 roof pressures of a plate, plate 136 cooperates the wall 130 that leads the device 13 that contracts, and packed into (as shown in Figure 4) in the thimble 11 by mutual group, therefore, increase two in back-moving springs 134 when assembling, be at existing drive axle 12, lead contract device 13 in conjunction with after combined again, and back-moving springs 134 are separately by plate 136 crimping in two, insert in the lump in thimble 11, so promptly do not have not easy-to-assemble problem installing, this is first feature of the present invention.

Subsidy plate 14 is the members that are increased, can make lockset more firm, this is the present invention's second feature, this subsidy plate 14 is enclosed within the central siphon 131 that leads the device 13 that contracts with a hole 141, and this subsidy plate 14 has two pin 142 and posts for 122 one-tenth with the location-plate that drives axle 12, traditional lockset is established hole 1221 by location-plate 122 and is screwed on thimble 11 for bolt 15, this traditional combination is to adapt to pulling force that flat handle produces because of the big arm of force and torsion, for this reason, subsidy plate 14 of the present invention is promptly in this shortcoming of improvement, establishing screw 143 by subsidy plate 14 screws for bolt 15, this bolt 15 is penetrated with location-plate 122 simultaneously and interior cover plate 21 is fixed, to remedy location-plate 122 and to lead the not enough place of device 13 by lug 138 combinations of contracting; Again, two fixture blocks 144 that protrude about subsidy plate 14 has itself, fixture block 144 can be entrapped in the hole, cave, location (as shown in Figure 5) of door.Setting up of plate 14 of subsidy can reach following effect; (1) is entrapped in the hole, cave, location of door with fixture block 144, so can prevents to force torsional mode to rotate to lead the device thereby lockset is destroyed of contracting.(2) because subsidy plate 14 is established fixture block 144, the circular hole outside of crossing the threshold in its arc tips checkpost (shown in Fig. 3,5) is so also can't reach demolition purpose with powerful drawing mode.

Outer handle 3 itself can be enclosed within central siphon 131, and snapped in by the spacer 137 in the central siphon 131 with locating slot 31, form outer handle 3 and be incorporated into central siphon 131, outer handle 3 holds to go into for core group 33 with an axis hole 32, core group 33 has a bossy body 331, and bossy body 331 can stretch into the combination bore 35 of handle 3 outside, and the two has inserted a positioning block 34, this locating piece 34 is provided with elastic projection 341 and can be protruded by the locating hole 36 of outer handle 3, makes core group 33 hold to go into fixing.This projection 341 can be pressed by pressure, makes core group 33 be easy to take out, and to reach the purpose that is convenient for changing the core group, this structure is the present invention's the 3rd feature.

The present invention's structure can make traditional loudspeaker lockset also can use flat handle combination instead, so, can make things convenient for the individuals with disabilities to use, and this lockset is structurally safer, and does not also increase trouble in assembling, and its effect has remarkable enhancement.
