Abstract
A clutch mechanism for a lock comprises handles (1) and (2) and a transmission shaft (3), wherein two ends of the transmission shaft (3) are respectively inserted into inner holes of the handles (1) and (2). The transmission shaft (3) is a single and integral component. When handle (1) rotated, handle (1) passed through contact surface C and driven transmission shaft (3) and rotate, and transmission shaft (3) can idle a certain angle relative to handle (2), so, when handle (1) rotated, handle (2) can not follow the rotation. The situation is the same when the handle (2) is turned to open the door. The clutch mechanism for the lock has the characteristics of simple structure, convenience in installation, reliability in work, good manufacturability, low cost and the like.
Description
The utility model relates to the clutch of a kind of mechanical device, particularly a kind of door lock.
Lock with the primary condition that clutch should satisfy is: rotate certain one handle when opening the door in certain scope, another handle keeps original state constant.Existing lock is various with clutch form of structure, and the complicated and simple degree of structure and the reliability of work etc. are widely different.The at present domestic a kind of lock that generally uses generally comprises six parts with clutch, and external comparatively advanced a kind of lock also comprises five parts with clutch, and structure is all complicated, and cost is higher, installs inconvenient.
The purpose of this utility model is for a kind of novel lock clutch is provided.
The purpose of this utility model is achieved in that a kind of lock clutch of structure, comprises handle and power transmission shaft, it is characterized in that the handle endoporus is inserted at the power transmission shaft two ends respectively.
Lock clutch of the present utility model, its feature are that also described power transmission shaft is single, integrated member.
According to the assembling condition of power transmission shaft and handle, when a handle rotated, this handle drove power transmission shaft by contact surface and rotates, and power transmission shaft is the certain angle of another handle idle running relatively, so when a handle rotated, another handle was static.
Advantage of the present utility model is: this structure has characteristics such as simple in structure, easy for installation, reliable operation, good manufacturability, cost be low.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the assembling schematic diagram of lock of the present utility model with the main running part of clutch and door lock.
Fig. 2 is the concrete structure figure schematic diagram of lock of the present utility model with clutch.
Fig. 3 is the distressed structure schematic diagram of Fig. 2.
Fig. 4 is the at present domestic a kind of lock clutch schematic diagram that generally uses.
Fig. 5 is external comparatively advanced a kind of lock clutch schematic diagram.
A kind of lock clutch comprises handle 1,2 and power transmission shaft 3, it is characterized in that, handle 1,2 endoporus are inserted at power transmission shaft 3 two ends respectively.Described power transmission shaft 3 is single, integrated member.
Section A, the B of Fig. 2, Fig. 3 represents the assembling condition of power transmission shaft 3 and handle 1,2 respectively.Press the direction shown in the arrow when rotating when handle 1, handle 1 drives power transmission shaft 3 by contact surface C and rotates, and by section B as can be known, power transmission shaft 3 is the certain angle of handle 2 idle running relatively, so when handle 1 rotation, handle 2 can and then not rotate.Situation when turning handle 2 opens the door herewith.
Fig. 4 is the at present domestic a kind of lock clutch schematic diagram that generally uses, and its operating principle is: when handle 1 rotated by the diagram direction of arrow, part 5 and then rotated, and by part 6 drive parts 4 and power transmission shaft 3, handle 2, finished the action of opening the door; When handle 2 rotated in certain angular range by the diagram direction of arrow, handle 1 can and then not rotate.Compare with the structure of Fig. 2, Fig. 3, have two defectives: the first, when handle 1 rotated, handle 2 can and then rotate; The second, many three members, promptly 4,5,6.
Fig. 5 is external comparatively advanced a kind of lock clutch schematic diagram.Operating principle is: when handle 1 rotated by the diagram direction of arrow, power transmission shaft 3 drove part 5 and finishes the action of opening the door.Part 4 and part 5 are matched in clearance, and handle 2 can and then not rotate.Situation when opening the door with handle 2 herewith.Compare with Fig. 2, Fig. 3, although principle, function are identical, yet, still have more part 4,5 on the structure, and used a power transmission shaft 3 more.
Lock clutch of the present utility model, simple in structure, easy for installation, reliable operation, good manufacturability, cost are low.
Claims (4)
1, a kind of lock clutch comprises handle (1), (2) and power transmission shaft (3), it is characterized in that, power transmission shaft (3) two ends are inserted handle (1), (2) endoporus respectively.
2, lock clutch according to claim 1 is characterized in that, described power transmission shaft (3) is single, integrated member.
3, lock clutch according to claim 1 is characterized in that, when handle (1) rotates, handle (1) drives power transmission shaft (3) by contact surface C and rotates, and power transmission shaft (3) is the certain angle of handle (2) idle running relatively, so, when handle (1) rotated, handle (2) was static.
4, lock clutch according to claim 1 is characterized in that, when the same turning handle of the situation of turning handle (2) when opening the door (1), promptly handle this moment (1) is static.
