Among the above-mentioned technical scheme, the bearing plays the effect of buffering, has advantages such as rotate smoothly, silence, simple structure, and processing and installation are all very convenient.

As a further arrangement of the utility model, the groove is cylindrical, the square hole is positioned on the bottom surface of the groove, a spring for providing buffering elastic force for the lock tongue is arranged in the square hole, the inner ring of the bearing is sleeved on the lock tongue, and the inner wall of the inner ring of the bearing is in clearance fit with the lock tongue.

Among the above-mentioned technical scheme, the whole structure that is the invagination of recess, the quad slit is the sunken of recess bottom surface, and its profile and spring bolt adaptation play the effect of linkage, and the bearing housing is established on the spring bolt, and is embedded in the recess, and the circumference inner wall fixed connection of its outer lane and recess, inner circle and spring bolt clearance fit make the handle body when rotating, through the bearing buffering, avoid the friction.

As a further provision of the utility model, the depth of the recess is equal to the thickness of the bearing.

As a further arrangement of the utility model, the bearings are ball bearings.

As a further arrangement of the utility model, the handle body comprises a handle portion and a connecting portion which is arranged in a bending manner, and the groove is located on the connecting portion.

As a further arrangement of the utility model, a fixing hole communicated with the square hole is arranged on the peripheral surface of the connecting part, and a fixing pin is arranged on the fixing hole.

The utility model is further described below with reference to the accompanying drawings.

Detailed Description

The specific embodiment of the utility model is shown in fig. 1-2, and the lever handle structure of the door lock comprises a lever handle body 1, wherein a square hole 11 matched with a bolt 2 is formed in the lever handle body 1, a groove 12 is formed in the end face, provided with the square hole 11, of the lever handle body 1, a bearing 3 is installed in the groove 12, the circumferential inner wall of the groove 12 serves as a bearing seat of an outer ring 32 of the bearing 3, and the inner diameter of an inner ring 31 of the bearing 3 is larger than the diagonal length of the square hole 11.

The bearing 3 plays a role in buffering, has the advantages of smooth rotation, silence and the like, and is simple in structure and convenient to process and install. The handle body 1 here both can be the handle in the door also can be the handle outside the door, and the inside and outside handle of lock all is provided with bearing 3 promptly, and it is better to rotate the effect.

The groove 12 is cylindrical, the square hole 11 is located on the bottom surface of the groove 12, a spring 111 which provides buffering elastic force for the bolt 2 is arranged in the square hole 11, the inner ring of the bearing 3 is sleeved on the bolt 2, and the inner wall of the inner ring of the bearing 3 is in clearance fit with the bolt 2.

The whole sunken structure that is of recess 12, quad slit 11 is the sunken of recess 12 bottom surfaces, and its profile and spring bolt 2 adaptation play the effect of linkage, and 3 covers of bearing are established on spring bolt 2, and embedded in recess 12, its outer lane and the circumference inner wall fixed connection of recess 12, inner circle and 2 clearance fit of spring bolt make handle body 1 when rotating, cushion through bearing 3, avoid the friction.

The bearing 3 inner race may be connected to other parts of the lock, such as the lock face plate or other connections.
