The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation on the present application.

[0028] As shown in Figures 1-6 a door hand grip, comprising a hand grip back plate 1 and a hand grip arm 2 transversely rotatingly mounted on the hand grip back plate 1, and further comprising a hand grip part 3, as shown in Figure 1 the hand grip part 3 is transversely rotatingly mounted on the hand grip back plate 1, i.e. the axis of rotation of the hand grip part 3 relative to the hand grip back plate 1 is parallel to the axis of rotation of the hand grip arm 2 relative to the hand grip back plate 1, the hand grip part 3 is located on the outside of the hand grip back plate 1, and the hand grip arm 2 is located on the inside of the hand grip back plate 1;

[0029] Specifically, a recessed part 10 is processed on the hand grip back plate 1, and the hand grip part 3 is transversely rotatingly mounted in the recessed part 10;

[0030] The back plate 1 of the handle has a through hole 11, and the handle part 3 is provided with a contact part 30 which penetrates the through hole 11 and contacts the handle arm 2. When the handle part 3 is rotated, the contact part 30 contacts the handle arm 2 to make the handle arm 2 penetrate the through hole 11 and contact the handle arm 2. The back plate 1 of the handle is provided with a limiting surface, and the handle part 3 is provided with a limiting part which contacts the limiting surface. The limiting part and the contact part 30 are located on both sides of the handle part 3 relative to the rotation axis of the back plate 1 of the handle. Specifically, the diameter of the through hole 11 is larger than the outer diameter of the part of the contact part 30 located in the through hole 11.

[0031] The handle arm 2 and the back plate 1 of the handle are provided with an elastic recovery part 4. When no external force is applied, the limiting part contacts the limiting surface, and the contact part 30 contacts the handle arm 2. When the handle part 3 is pulled outward, the limiting part is separated from the limiting surface, and the contact part 30 presses the handle arm 2 to rotate the handle arm 2 and make the elastic recovery part 4 deform.

[0032] Specifically, the elastic recovery part 4 is a torsion spring. The handle arm 2 is provided with a rotating column 20 which is integrally formed with other structures of the handle arm 2 and is supported. The rotating column 20 of the handle arm 2 is transversely rotatably installed on the back plate 1 of the handle by a rotating pin. The torsion spring is sleeved on the outside of the rotating column 20, and one end of the torsion spring is fixed on the handle arm 2, and the other end of the torsion spring is fixed on the back plate 1 of the handle.

The side of the transmission rod 5 away from the spherical connecting part 50 is slidably connected with the limiting hole. The transmission rod 5 slides in the limiting hole to touch and open / close the switch, and then the transmission rod 5 controls the closing of the contact switch (it is to be noted that the contact switch is a structure installed on the back plate 1 of the handle in the prior art, and the structure thereof will not be described in detail here). During the rotation of the handle arm 2, the transmission rod 5 starts to rotate in the sliding groove 121 and slides the transmission rod 5 to make the handle rod control the opening / closing of the touch switch.

[0036] Preferably, the outer side of the cylindrical protrusion 12 is provided with a communication groove 122 along the radial direction thereof, which is in communication with the sliding groove 121 and the mounting hole 120, facilitating the mounting of the connecting rod.

[0037] Preferably, the side of the handle arm 2 in contact with the abutting portion 30 is provided with a plurality of first limiting grooves 21, and the abutting portion 30 is provided with a first rolling element 7, which rolls in the first limiting groove 21 when the handle portion 3 abuts against the handle arm 2; on the one hand, the abutting portion 30 and the handle arm 2 are reduced in abrasion, and on the other hand, the relative rotation between the handle arm 2 and the handle portion 3 is limited.

[0038] Preferably, the abutting portion 30 is located between the handle back plate 1 and the handle arm 2, and the abutting portion 30 is detachably mounted on the handle portion 3, facilitating the mounting and dismounting of the handle.

[0039] Preferably, when subjected to an external force, the elastic recovery element 4 is in a deformed state, thereby ensuring that the elastic recovery element 4 can drive the handle arm 2 to return to the original position when subjected to a force.

[0040] Preferably, the handle arm 2 is provided with a limiting platform 22, and the handle back plate 1 is provided with a second limiting element 8, which abuts against the limiting platform 22 when not subjected to an external force.

[0041] Preferably, the second limiting element 8 is provided with a second rolling element 9, and the limiting platform 22 is provided with a second limiting groove 220, in which the second rolling element 9 rolls, facilitating the limiting of the handle arm 2.

[0042] Specifically, as Figure 4 described, the second limiting element 8 is provided with a mounting ring groove 80, the handle back plate 1 is provided with a mounting plate 13, the mounting plate 13 is provided with a connecting hole, the second limiting portion penetrates through the connecting hole, and the mounting ring groove 80 abuts against the mounting hole 120; the second limiting element 8 has a portion located on one side of the mounting plate 13, and the second limiting portion has a portion located on the other side of the mounting plate 13; the portion of the second limiting portion in contact with the mounting plate 13 is made of an elastic material, reducing the wear of the parts and achieving the effect of noise reduction;
