Description

Novel door lock handle device

Technical field

The utility model relates to a kind of lockset, and more particularly it relates to a kind of door lock handle device.

Background technology

In prior art, application number be 98123666.9 Chinese patent document disclose a kind of door lock handle device, this device is by the positive and negative rotation for the key handle of the switching manipulation of door, the upper lock shaft be connected with it is rotated and carry out door unblank lock, in more detail, relate to so a kind of door lock handle device, namely when locking can key handle from lock shaft take off, taking by this key handle, upper lock shaft to taking up a main body automatically locking, on the other hand, by the insertion of key handle, locking is removed immediately.

Its structure can be clearly expressed by the accompanying drawing of above-mentioned patent, popular says, lock body comprises upper bed-plate and lower bottom base, upper bed-plate offers keyhole, install lock core between Up/down base, non-locking states, upper bed-plate coaxial rotating is connected to lower bottom base, mainly through upper bed-plate is provided with rotating shaft, rotating shaft passes formation from the axis hole of lower bottom base.Under locking states, upper bed-plate is lockable and cannot rotates, and only only has to insert key handle to carry out unblock rear rotatable.The lock of said structure, the position of its upper bed-plate and lower bottom base must be fixed, namely upper bed-plate must be adjacent to lower bottom base, axial displacement can not be there is, this patent document be reach like this " upper lock shaft (being equivalent to rotating shaft) is plugged in the axis hole taking up a main body (being equivalent to lower bottom base), and the square shaft portion, front end of upper lock shaft is pressed into square slip-off preventing annular slab." this patent passes axis hole by rotating shaft and enter annular slab at end riveting and play the object preventing upper bed-plate and rotating shaft from moving axially.For said structure, although annular slab riveting can play slip-off preventing object in the structure of roller end, but this annular slab is only the frictional force produced by riveting to be fixed, itself does not possess position limiting structure, this just makes to pull from outside to be easy to just by the end roof fall of annular slab from rotating shaft the process of upper bed-plate, security performance is not high, and installs the maintenance of annular slab to the later stage by the mode of riveting, and dismounting is all inconvenient.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of novel door lock handle device, and its structure is more reasonable, and performance is more stable, keeps in repair more convenient.

For achieving the above object, the utility model provides following technical scheme: a kind of novel door lock handle device, include lock body, the key handle of upper bed-plate, lower bottom base and lock core composition, upper bed-plate is connected with rotating shaft, lower bottom base is provided with axis hole, and described rotating shaft passes lower bottom base from axis hole, and the part that described rotating shaft passes axis hole is provided with annular groove, be embedded with jump ring in described groove, described jump ring and lower bottom base are formed conflicts.

Described key handle bends U-shaped structure, and one end of key handle is provided with operation dog.

The side of the relative jump ring of described lower bottom base is installation portion, and described installation portion is provided with external screw thread and the mounting nuts with external screw thread adaptation.

The side of the relative jump ring of described lower bottom base is fitted with rubber layer.

By adopting technique scheme, the utility model have been abandoned in prior art at roller end riveting annular slab to play the mode preventing upper bed-plate axial displacement, but by rotating shaft, the part passed outside axis hole arranges groove, setting-in jump ring in a groove, and jump ring and lower bottom base are formed and conflict, namely jump ring is installed on the position that rotating shaft has just passed axis hole.Formed by jump ring and lower bottom base and conflict, thus prevent upper bed-plate from driving rotating shaft generation axial displacement, because jump ring is for being flush-mounted in groove, groove plays fixing and spacing effect to jump ring, effectively prevent jump ring from coming off, and jump ring mounts and dismounts by Circlip tongs, keep in repair convenient, its structure is more reasonable, uses more stable.

Detailed description of the invention

Referring to figs. 1 through Fig. 3, the utility model embodiment is described further.

Novel door lock handle device described in the present embodiment, as shown in Figure 2, include lock body 1, the key handle 2 of upper bed-plate 11, lower bottom base 12 and lock core composition, upper bed-plate 11 is connected with rotating shaft 13, lower bottom base 12 is provided with axis hole, described rotating shaft 13 passes lower bottom base 12 from axis hole, all be as good as with prior art with upper part, seldom repeat herein, its feature is, the part that described rotating shaft 13 passes axis hole is provided with the groove 15 of annular, is embedded with jump ring 3 in described groove 15, and described jump ring 3 is formed with lower bottom base 12 and conflicts.

By adopting technique scheme, the utility model have been abandoned in prior art at rotating shaft 13 end riveting annular slab to play the mode preventing upper bed-plate 11 axial displacement, but groove 15 is set by the part passed outside axis hole in rotating shaft 13, setting-in jump ring 3 in groove 15, and jump ring 3 and lower bottom base 12 are formed and conflict, namely jump ring 3 is installed on the position that rotating shaft 13 has just passed axis hole.Formed by jump ring 3 and lower bottom base 12 and conflict, thus prevent upper bed-plate 11 from driving rotating shaft 13 that axial displacement occurs, because jump ring 3 is for being flush-mounted in groove 15, groove 15 pairs of jump rings 3 play fixing and spacing effect, effectively prevent jump ring 3 from coming off, and jump ring 3 mount and dismount, and keeps in repair convenient by jump ring 3 pincers, its structure is more reasonable, uses more stable.

Further optimization, described key handle 2 bends U-shaped structure, and one end of key handle 2 is provided with operation dog 21.Key handle 2 includes operation dog 21, and operation dog 21 is inserted the keyhole of upper bed-plate 11 to unlock.Traditional key handle 2 is staight shank, and lock body 1 is installed on door-plate usually, and when the key handle 2 of staight shank shape inserts in keyhole, key handle 2 is almost adjacent to door-plate, inconvenient hand-held.This programme by key handle 2 is set to U-shaped structure, when key handle 2 is inserted in keyhole, handle and can certain distance be preserved between door-plate, facilitate hand-held use.

Further, as shown in Figure 2, the side of the relative jump ring 3 of described lower bottom base 12 is installation portion 14, and described installation portion 14 is provided with external screw thread and the mounting nuts 4 with external screw thread adaptation.During installation, by installation portion 14 through door-plate, screw mounting nuts 4 in the inner side of door-plate, door-plate is held between lower bottom base 12 and mounting nuts 4 and carries out thus fixing lock body 1.The end of rotating shaft 13 is provided with the bolt 5 for installing jam plate (not shown).

Further, the side of the relative jump ring 3 of described lower bottom base 12 is fitted with rubber layer 16.Arrange rubber layer 16 can prevent install lock body 1 time, scratch door-plate.And there is better tightness and fastening effect when mounted.

The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all within design concept of the present utility model, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
