For achieving the above object, the utility model adopts insurance knob assembly in a kind of door lock, comprise a knob, knob main body one end forms the knob-operated handle, be provided with shrinkage pool on the outer face of the other end vertically, and be connected by other assembly in the Arming Assembly in shrinkage pool and the door lock, on the cylindrical of knob upper concave hole one side, form cone boss as barb, the taper fixed cover of a sheathed both ends open on the knob main body, the axial length of taper fixed cover is less than the length of knob main body, the cylindrical of its inwall close neighbour knob main body, taper fixed cover one end is pressed on the cone boss inboard, the cylindrical upper edge circumference of taper fixed cover is evenly distributed with the groove more than 2 or 2, the cone boss of groove opening on knob.
The utility model is dismantled knob for convenience, and the cylindrical upper edge circumference of the cone boss on the knob is evenly distributed with one or more grooves.
For easy to assembly, other end cylindrical relative with groove on the taper fixed cover is provided with annular boss.
For in assembling, make taper fixed cover front end have elasticity, it is good being uniformly distributed with 4 grooves on the cylindrical of taper fixed cover along the circumference, perhaps be uniformly distributed with 2 grooves on the cylindrical of taper fixed cover along the circumference, the width of groove is greater than the cylindrical of groove opening one end on 1/4th the taper fixed cover.
The groove that the utility model further is set on the knob main body is the best for 2 of being symmetrically distributed.
In order better to realize cooperating of taper fixed cover and knob, make knob be difficult for taking place left and right swing in operation, the knob main body adopts taper shape.
The utility model utilizes the elastic characteristic of plastics, replaces original snap ring or back-up ring by setting up a taper fixed cover, makes things convenient for the installation of knob.On the cylindrical of knob upper concave hole one side, form cone boss as barb, the taper fixed cover of a sheathed both ends open on the knob main body, the axial length of taper fixed cover is less than the length of knob main body, the cylindrical of its inwall close neighbour knob main body, taper fixed cover one end is pressed on the cone boss inboard, the cylindrical upper edge circumference of taper fixed cover is evenly distributed with the groove more than 2 or 2, the cone boss of groove opening on knob.When assembling, earlier knob is inserted in from the installing hole front end on the handle, the taper fixed cover is packed into from the installing hole rear end on the handle, knob band cone boss one side is inserted in the taper fixed cover, because the cylindrical upper edge circumference of taper fixed cover is evenly distributed with groove, make taper fixed cover front end have elasticity, can spreading, make cone boss by and be against taper fixed cover front end, because the diameter of cone boss is greater than taper fixed cover front opening diameter, the taper fixed cover can not come off, and knob just is fixed on the handle, finishes the assembling of handle; If the dismounting knob the groove of instrument from the installing hole rear end insertion knob of handle with similar tweezers, with taper fixed cover spreading, can be pulled down knob.The utility model is simple in structure, and easy accessibility is practical.
