[0002] Door handles are indispensable door accessories that are both decorative and functional. Traditional door handles are easily hit by the wall when the door is opened vigorously if the door stopper is loose or not installed. Over time, the door handle will become loose or deformed, affecting its service life. At the same time, the wall is also easily damaged.
[0003] Therefore, the utility model provides a door handle with a protective structure to solve the above problems. Utility Model Content
[0004] In view of the problems existing in the prior art, the utility model discloses a door handle with a protective structure. The technical solution adopted is that it includes a rotating shaft, the rear end of the rotating shaft is fixedly connected to the mounting plate, the front circumferential edge of the mounting plate is fixedly connected to the external fixed sleeve, a spring is movably mounted on the rotating shaft in the external fixed sleeve, and a buffer ring is also movably mounted on the rotating shaft at the front end of the spring, and support columns are arranged in a circumferential array on the front circumferential edge of the buffer ring, and the support columns respectively pass through the left end of the outer handle, and the rear side wall of the left end of the outer handle is fixedly inserted together with the rotating shaft, and the front end face of the support column is fixedly connected to the buffer structure.
[0005] As a preferred solution of the utility model, a threaded hole is provided on the side wall of the front end of the rotating shaft; the threaded hole is provided to facilitate fixation with the left end of the outer handle.
[0006] As a preferred solution of the utility model, four support columns are provided; such a design facilitates uniform force on the circumferential edge of the buffer ring and improves the smoothness of its compression spring.
[0007] As a preferred solution of the utility model, the outer handle includes a fixed seat at the left end, a countersunk hole is opened in the center of the rear side wall of the fixed seat, the front end of the rotating shaft is inserted into the countersunk hole, the upper side wall of the fixed seat is opened with a hexagon socket screw to lock the rotating shaft, and the circumferential side wall of the fixed seat is fixedly connected to the handle.
[0008] As a preferred solution of the utility model, the buffer structure includes a buffer seat, the buffer seat is made of rubber material, and the front end surface of the buffer seat is fixedly connected to a conical suction cup; by adopting the structural design of the buffer seat and the conical suction cup, the front end of the door handle can be provided with multiple buffering protections, thereby improving the stability of its protection.
[0009] As a preferred solution of the utility model, air holes are provided on the edge of the circumferential side wall of the conical suction cup; by providing the air holes on the conical suction cup, it is prevented from being adsorbed on the wall and causing damage to the wall when the outer handle is pulled.
[0010] The beneficial effects of the utility model are as follows: by installing a spring on the rotating shaft and cooperating with a buffer ring, when the door is opened and the door handle hits the wall, the conical suction cup first contacts the wall surface, and as it is squeezed, the air inside the conical suction cup is slowly discharged, thereby alleviating a part of the impact force, and then squeezing the buffer seat, the buffer seat squeezes the support column, the support column squeezes the buffer ring, the buffer ring compresses the spring, and finally removes the impact force, thereby effectively preventing the door handle from being hit by the wall and the wall from being damaged when the door is opened vigorously, thereby improving the ability of the door handle to protect against impact.

DETAILED DESCRIPTION
[0016] Example 1
[0017] like Figures 1 to 4As shown, the door handle with a protective structure described in the utility model adopts a technical solution that includes a rotating shaft 1, the rear end of the rotating shaft 1 is fixedly connected to a mounting plate 11, the front circumferential edge of the mounting plate 11 is fixedly connected to an external fixing sleeve 12, a threaded hole 13 is provided on the side wall of the front end of the rotating shaft 1, a spring 2 is movably mounted on the rotating shaft in the external fixing sleeve 12, a buffer ring 3 is also movably mounted on the rotating shaft at the front end of the spring 2, support columns 31 are arranged in a circumferential array on the front circumferential edge of the buffer ring 3, and 4 support columns 31 are arranged, and the support columns 31 respectively pass through the left end of the outer handle 4, and the The outer handle 4 includes a fixed seat 41 at the left end, and a countersunk hole 411 is provided in the center of the rear side wall of the fixed seat 41, and the front end of the rotating shaft 1 is inserted into the countersunk hole 411. The upper side wall of the fixed seat 41 has a hole for screwing a hexagon socket screw 42 to lock the rotating shaft 1. The circumferential side wall of the fixed seat 41 is fixedly connected to the handle 43, and the front end face of the support column 31 is fixedly connected to the buffer structure 5. The buffer structure 5 includes a buffer seat 51, and the buffer seat 51 is made of rubber. The front end face of the buffer seat 51 is fixedly connected to a conical suction cup 52, and an air hole 521 is provided on the edge of the circumferential side wall of the conical suction cup 52.
[0018] The working principle of the utility model is as follows: when in use, the door handle device is installed on the lock hole of the door, and it is unnecessary to drill holes on the wall or the ground to install the door suction. When opening the door, the conical suction cup 52 of the door handle first contacts the wall. With the squeezing, the air in the conical suction cup 52 is slowly discharged through the air hole 521, and then the buffer seat 51 is squeezed. After the buffer seat 51 is squeezed, it drives the support column 31 to move in the opposite direction of the wall, thereby pushing the buffer ring 3 to squeeze the spring 2. With the gradual compression of the spring 2, the impact force is slowly unloaded, thereby preventing the door handle from being hit by the wall.
