Description

The telescopic door handle

The utility model relates to a kind of handle, is the improvement of grip structure of the door in a kind of room or cabinet specifically.

The handle of the door in room and cabinet is generally given prominence to and is fixed on outside the shop front.When door was opened, this door handle may bump with contiguous door-plate, wall or other objects, and the handle of door and contiguous door-plate, wall or other objects all can cause damage.Before the utility model design is finished, not seeing the handle identical with the utility model structure as yet uses in daily life, not seeing the door handle identical with the utility model structure has sale on market, it is on the books in the literature also not see the door handle identical with the utility model structure.

The purpose of this utility model is to provide a kind of telescopic door handle, in the time of within needs are with door handle retraction door body, within can indentation door body, when needs protrude in door handle outside the shop front, can protrude in the telescopic door handle outside the shop front, when door is opened, can avoid door and door-plate, wall or other objects of vicinity to bump, cause damage.

For achieving the above object, the utility model adopts following technical proposals:

The telescopic door handle, by housing, handle, spring, packing ring, last seal ring, following capping and screw are formed, it is cylindric that housing is, the bottom center of housing cylinder have with its bottom surface be that the center of one is the hollow cylinder of column type, the outside of this cylinder is by three groups of slideways of being made up of two parallel chute wall that are cross quadrature, there is the chute wall that is the type position at the 4th group of slideway, its corner forms the plane parallel with the housing bottom surface, position at the 4th group of slideway, vertical with chute wall have a plane, one convex is arranged between the bottom surface of this plane and housing cylinder, and the inner tube wall of housing cylinder is the corresponding chute in position of the slideway that two chute wall of cross quadrature form by the outside with cylinder; Handle is made by steel or alloy, the hollow cylinder shape that is end sealing, end in sealing has and is the recessed handle neck of imperial palace circlet shape outside the diameter, the other end that is connected as a single entity with it be handle cylinder, have with it at the inner face of cylindrical handle and to be the cylindrical hollow spring position holder of one, the slightly larger in diameter of hollow spring position holder is in the diameter of spring, be the corresponding three groups of slide rails of three groups of slideways that two chute wall by parallel of cross quadrature are formed at the inner face of cylindrical handle by outside with the housing cylinder, on cylindrical the 4th group of position of handle, have one with the corresponding slightly wide slide rail in position of the 4th group of slideway of the hollow cylinder of housing cylinder, with the housing cylinder minor axis that one vertical insertion is arranged on the inwall of handle of corresponding position on one plane parallel with the bottom surface of housing cylinder is arranged, be fixed with at right angles asymmetric recessed polygon unit of plastic of two minor faces on the minor axis, this unit of plastic can rotate on inwall; The outer diameter through the hollow cylinder of the bottom center that is slightly less than the housing cylinder of spring is arranged and the corresponding locating piece of the chute of housing in the outside of cylindrical handle; Last seal ring has the threads engaged of screw thread and housing cylinder; Following capping links to each other with the housing cylinder by screw.Housing is made of plastics, and handle 2 is made by steel or alloy.

The position that door handle is installed in the preparation of the door in room or cabinet, perforate, the diameter in hole is identical with the external diameter of the utility model housing cylinder, to descend capping to be buckled in a body tapping, the utility model housing will be inserted perforate, trip bolt, spring is inserted the hollow cylinder of bottom center of housing cylinder, according to corresponding position handle is inserted the housing cylinder, also will go up seal ring is screwed into the housing cylinder to put packing ring, then finishes installation of the present utility model.

The utility model has following effect and positive effect:

When pressing the student hand, spring is compressed, the outer corresponding locating piece of chute with the barrel housing cylinder of the cylinder of the other end of handle slides along the chute of the barrel of housing cylinder, rotary on the inwall of housing cylinder, the rectangular asymmetric recessed polygon unit of plastic of two minor faces then slides into the bottom of housing cylinder always, unit of plastic is stuck on the parallel plane, the bottom surface with the housing cylinder of housing cylinder, handle and housing cylinder are blocking, when being installed in when last, door handle then presents the state in the retraction door body; When pressing handle once more, spring is compressed again, and unit of plastic departs from cylinder, by the effect of spring, handle protrudes in outside the housing, outside just outstanding and the shop front, when door is opened, avoid door and door-plate, wall or other objects of vicinity to bump, cause damage.

Below in conjunction with accompanying drawing structure of the present utility model is done explanation in further detail:
