[0003] The problem with the prior art is that in daily life, when people open the door, they may use too much force and hit the door against the wall. Some doors without anti-collision columns are in a slightly open state, and a strong wind blows and hits the door against the wall. Since the door handle protrudes from the surface of the door body and is connected to the lock body, when the door handle hits the wall, the door handle and the lock body will be impacted at the same time. If this continues for a long time, the door handle and the lock body will become loose or damaged. In order to protect the door handle, an anti-collision door handle is proposed. When a collision occurs, the impact force can be fully alleviated, and the wall can be protected to a certain extent while protecting the door handle. Utility Model Content
[0004] In view of the problems existing in the prior art, the utility model provides an anti-collision door handle, which has the advantage of alleviating the impact force on the door handle, and solves the problem that in daily life, when people open the door, they use too much force and hit the door against the wall. Some doors without anti-collision columns are in a slightly open state, and a strong wind blows and hits the door against the wall. Since the door handle protrudes from the surface of the door body and is connected to the lock body, when the door handle hits the wall, the door handle and the lock body will be impacted at the same time. If this continues for a long time, the door handle and the lock body will become loose or damaged. In order to protect the door handle, an anti-collision door handle is proposed, which can fully alleviate the impact force when a collision occurs, and protect the door handle while also providing a certain degree of protection to the wall.
[0005] The utility model is implemented as follows: an anti-collision door handle comprises a shell, a connecting rod, a buffer plate and a buffer block, the rear side of the shell is movably connected to the front side of the connecting rod, the front side of the shell is movably connected to the rear side of the buffer plate, the front side of the buffer plate is fixedly connected to the rear side of the buffer block, a cavity is opened inside the shell, a buffer mechanism is arranged inside the cavity, and the front side of the buffer mechanism is fixedly connected to the rear side of the buffer plate.
[0006] As a preferred embodiment of the present invention, limiting blocks are fixedly connected to the left and right sides of the buffer plate, and the inner wall of the cavity is provided with a limiting groove used in conjunction with the limiting block. By providing the limiting block and the limiting groove, the moving direction and stroke of the buffer plate can be limited when it moves backward to prevent damage during use.
[0007] As a preferred embodiment of the utility model, the buffer mechanism includes a movable column, a horizontal plate and a compression spring. The front side of the movable column is fixedly connected to the rear side of the buffer plate, the rear side of the movable column is fixedly connected to the front side of the horizontal plate, the rear side of the horizontal plate is fixedly connected to the front side of the compression spring, and the rear side of the compression spring is fixedly connected to the inner wall of the cavity. By setting up the buffer mechanism, the door handle can be protected and its recoil force can be fully released to prevent damage to the door handle or the wall.
[0008] As a preferred embodiment of the utility model, a travel rod is fixedly connected to the inside of the cavity, and the cross plate is sleeved on the surface of the travel rod. By setting the travel rod, the moving direction and stroke of the cross plate can be limited to ensure the normal use of the structure and prevent damage.
[0009] As a preferred embodiment of the utility model, two buffer columns are fixedly connected inside the cavity, the rear sides of the buffer columns are fixedly connected to the inner wall of the cavity, and the front sides of the buffer columns are in contact with the rear sides of the buffer plates. By providing the buffer columns, the buffer columns can replace the buffer mechanism to share part of the impact force, thereby extending the service life of the buffer mechanism.
[0010] As a preferred embodiment of the present invention, the buffer block and the buffer column are both made of rubber.

[0011] 1. The utility model sets a shell, a connecting rod, a buffer plate, a buffer block, a buffer mechanism and a buffer column for coordinated use. Through the buffer mechanism, when the door handle is impacted, its shell is protected, the buffer force is reduced and the wall surface is protected at the same time, so that in daily life, when people open the door, they may use too much force and hit the door against the wall. Some doors without anti-collision columns are in a slightly open state, and a strong wind blows and hits the door against the wall. Since the door handle protrudes from the surface of the door body and is connected to the lock body, when the door handle hits the wall, the door handle and the lock body will be impacted at the same time. If things go on for a long time, the door handle and the lock body will become loose or damaged. In order to protect the door handle, an anti-collision door handle is proposed. When a collision occurs, the impact force is fully alleviated, and the wall surface is protected to a certain extent.

[0018] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.
[0019] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.
[0020] like Figures 1 to 4 As shown, an anti-collision door handle provided by an embodiment of the utility model includes a shell 1, a connecting rod 2, a buffer plate 3 and a buffer block 4, the rear side of the shell 1 is movably connected to the front side of the connecting rod 2, the front side of the shell 1 is movably connected to the rear side of the buffer plate 3, the front side of the buffer plate 3 is fixedly connected to the rear side of the buffer block 4, a cavity 5 is opened inside the shell 1, a buffer mechanism 6 is provided inside the cavity 5, and the front side of the buffer mechanism 6 is fixedly connected to the rear side of the buffer plate 3.
[0021] refer to Figure 3 and Figure 4 The left and right sides of the buffer plate 3 are fixedly connected with limiting blocks 7, and the inner wall of the cavity 5 is provided with limiting grooves 8 used in conjunction with the limiting blocks 7.
[0022] By adopting the above solution, by providing the limiting block 7 and the limiting groove 8, the moving direction and stroke of the buffer plate 3 can be limited when it moves backward, so as to prevent damage during use.
[0023] refer to Figure 4The buffer mechanism 6 includes a movable column 601, a horizontal plate 602 and a compression spring 603. The front side of the movable column 601 is fixedly connected to the rear side of the buffer plate 3, the rear side of the movable column 601 is fixedly connected to the front side of the horizontal plate 602, the rear side of the horizontal plate 602 is fixedly connected to the front side of the compression spring 603, and the rear side of the compression spring 603 is fixedly connected to the inner wall of the cavity 5.
[0024] By adopting the above solution, the buffer mechanism 6 is provided to protect the door handle, and its recoil force can be fully released to prevent the door handle or the wall from being damaged.
[0025] refer to Figure 4 The interior of the cavity 5 is fixedly connected with a travel rod 9 , and the horizontal plate 602 is sleeved on the surface of the travel rod 9 .
[0026] By adopting the above solution, the travel rod 9 is provided to limit the moving direction and travel of the cross plate 602, thereby ensuring the normal use of the structure and preventing damage.
[0027] refer to Figure 4 Two buffer columns 10 are fixedly connected inside the cavity 5 , the rear side of the buffer column 10 is fixedly connected to the inner wall of the cavity 5 , and the front side of the buffer column 10 is in contact with the rear side of the buffer plate 3 .
[0028] By adopting the above solution, by providing the buffer column 10 , the buffer column 10 can replace the buffer mechanism 6 to share a part of the impact force, thereby extending the service life of the buffer mechanism 6 .

[0030] By adopting the above solution, by providing the buffer block 4 and the buffer column 10, when the door handle is hit, the housing 1 can have a certain buffering effect according to the characteristics of the rubber.
[0031] During use, when the door handle hits the wall, since the buffer block 4 is arranged on the front side of the buffer plate 3, the buffer block 4 will bear a large impact force, and the buffer block 4 pushes the buffer plate 3 to move backward along the moving trajectory provided by the limiting groove 8, and the buffer plate 3 pushes the moving column 601 to move backward, and the moving column 601 pushes the cross plate 602 to move backward along the moving trajectory provided by the stroke rod 9. When the cross plate 602 moves backward, the compression spring 603 is compressed, and the impact force is fully absorbed by the compression spring 603 and the buffer column 10.

Some doors without anti-collision columns are in a slightly open state, and a strong wind blows and hits the door against the wall. Since the door handle protrudes from the surface of the door body and is connected to the lock body, when the door handle hits the wall, the door handle and the lock body will be impacted at the same time. If things go on for a long time, the door handle and the lock body will become loose or damaged. In order to protect the door handle, an anti-collision door handle is proposed, which can fully alleviate the impact force when a collision occurs, and protect the door handle while also providing a certain degree of protection to the wall.
