[0019] To make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings.

[0020] See Figures 1 to 4 As shown, the embodiment of the present utility model provides a doorknob for a door, including doorknobs 1 symmetrically arranged on both sides of the door gap.

[0021] The embodiment of the present utility model has improved the structure and installation structure of the doorknob to solve the problems of pinching hands and complex installation procedures.

[0022] Specifically, the doorknob 1 is in a plate-like structure, and one side close to the door bends towards the door gap at a predetermined angle to form a handstop plate 11; an installation structure is provided on the back of the doorknob 1, and the installation structure includes an installation part 2 and a connecting column 24. The installation part 2 is arranged on the back of the doorknob 1. An installation groove 21 is provided on the installation part 1. One end of the connecting column 24 is installed on the door, and the other end is inserted into the installation groove 21 and fixedly connected to the installation groove 21.

[0023] Compared with the prior art, firstly, a handstop plate 11 is provided on one side of the doorknob close to the door gap. During the process of closing and opening the door, the human hand cannot reach into the door gap, effectively solving the problem of easy pinching of the hand. Secondly, an installation part 2 is provided on the back of the doorknob. The connecting column 24 in the blind hole on the door can be inserted into the installation groove 21 of the installation part 2 and fixedly connected to the installation groove 21, effectively reducing the number of holes drilled on the door body and reducing the installation difficulty.

[0024] Preferably, an installation counterbore 22 is provided on the side of the installation part 2 away from the door gap. A threaded groove 241 adapted to the installation counterbore 22 is provided on the connecting column 24. The installation counterbore 22 is fixedly connected to the threaded groove 241 through a bolt 23. During installation, the installation groove 241 is aligned with the connecting column 24, and the connecting column 24 is inserted into the installation groove 21 until the installation counterbore 22 is aligned with the threaded groove 241 on the connecting column 24, and then the bolt 23 is screwed in for fixed connection.

[0025] More preferably, positioning structures are provided at both the top and bottom of the installation part 2. The positioning structure includes a positioning rod 25, a positioning hole 242, and an elastic member 27. A positioning cavity 26 is provided on the installation part 2. One end of the positioning rod 25 passes through the positioning cavity 26 and extends into the positioning hole 242 provided on the connecting column 24. A handle 252 is provided at the other end of the positioning rod 25. A protrusion 251 is provided on the side surface of the positioning rod 25 in the positioning cavity 26. An elastic member 27 is provided between the inner wall of the positioning cavity 26 away from the installation groove 21 and the protrusion 251. Since the doorknob 1 is relatively large in volume, a positioning structure is required to pre-fix the doorknob and the connecting column on the door during installation, which can reduce the installation difficulty of the doorknob.

[0026] Most preferably, the elastic member 27 is a spring. The spring is sleeved on the positioning rod 25. One end of the elastic member is connected to the protrusion 251, and the other end is connected to the inner wall of the positioning cavity 26. Sleeving the spring on the positioning rod can, firstly, make the force on the positioning rod 25 more uniform, and secondly, save materials.

[0027] Preferably, a decorative part installation groove 12 is provided on the surface of the doorknob, and a decorative plate is provided in the decorative part installation groove 12. Setting the decorative plate can improve the aesthetic appearance of the doorknob.

[0028] Preferably, both ends of the side of the doorknob away from the door gap are chamfered structures. The chamfers are provided to reduce the damage suffered in a collision accident and improve the safety of the doorknob.

[0029] An embodiment of the present utility model further provides a door, including the above-mentioned doorknob.

[0030] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present utility model.
