Detailed Description

The embodiment of the retractable door handle of the present invention will be further described with reference to the accompanying drawings.

As shown in the accompanying drawings, the present embodiment is a retractable door handle, which includes an installation panel 1, the installation panel is attached to a door, a lock hole is opened on the front side of the installation panel, the lock hole is opposite to a lock in the door, a rotating member 2 is rotatably connected in the lock hole, when the rotating member is rotated to open the lock in the door, the rotating member can rotate in the lock hole under the driving of an external force, and the external force is from a user.

Specifically, end connection fixed handle 3 at the rotating member, be formed with the mounting groove at fixed handle's front end, be fixed adjustment handle in the mounting groove, adjustment handle includes telescopic link 4, peg graft in the mounting groove telescopic link one end slidable, hand (hold) 5 is being connected to the other end, can not the relative slip between hand (hold) and the telescopic link, the tip at the telescopic link is connected to the hand (hold), when the user pulling hand (hold), can stimulate the telescopic link and reciprocate to slide in the mounting groove.

The telescopic rod is provided with a sliding chute which is a double-section chute and consists of an upper section chute 6 and a lower section chute 7, the upper section chute is arranged on the top surface of the telescopic rod, the lower section chute is arranged in the telescopic rod, the upper section chute and the lower section chute are arranged in parallel up and down and have equal length, the end parts of the two ends of the upper section chute and the lower section chute are communicated up and down through a communication hole 8, and a spring pin 9 is inserted in the communication hole.

The spring pin comprises a pin shaft 91 which is inserted in the communicating hole, the top part of the pin shaft extends outside the telescopic rod, a spring 92 is fixed at the top of the pin shaft, a button 93 is supported on the spring, when a user presses the button, the pin shaft can be wholly pressed down to enable the bottom of the pin shaft to extend into the lower section groove, a beam 94 is arranged at the bottom of the pin shaft, the aperture of the middle section of the communicating hole is larger than the width of the lower section groove, so that after the bottom of the pin shaft extends into the lower section groove, the beam is in contact with the groove wall of the lower section groove, the bottom of the pin shaft is limited in the lower section groove until the pin shaft moves into the communicating hole at the other end part of the lower section groove, at the moment, the lower section groove releases the pressing on the beam, the pin shaft can be upwards reset under the restoring force of the spring, the button is popped outside the telescopic rod again, the button and the local pin shaft can be upwards protruded and extended in the key hole, and the pin shaft is connected with the hole wall of the key hole, so that the telescopic rod is prevented from continuously sliding forwards/backwards.

The telescopic link overcoat is equipped with folding plastic sheath 10, folding plastic sheath one end is connected on fixed handle, and the other end is connected on the hand (hold). On the one hand, the folding plastic sleeve can prevent external dust from entering the telescopic rod, and on the other hand, when the telescopic rod slides, the folding plastic sleeve can also play a role in noise reduction.

The above description is for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way, and modifications and variations can be made without departing from the principles of the present invention.
