[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] Please refer to Figure 1-Figure 4 The utility model discloses an anti-collision device, comprising:

[0028] An installation housing 100 is installed on a wall, and an installation notch 110 is provided on the installation housing 100;

[0029] The collision block 200 is used to contact the door. The collision block 200 is provided with the installation notch 110 and is detachably connected to the installation shell 100 , and the collision block 200 protrudes from the surface of the installation shell 100 .

[0030] In the present application, an installation notch 110 is opened on the installation shell 100, and the collision block 200 is arranged at the installation notch 110 and is detachably connected to the installation shell 100. When the collision block 200 is damaged, it only needs to be disassembled and replaced separately without disassembling the installation shell 100, thereby avoiding opening a hole in the wall again and reducing maintenance costs.

[0031] Specifically, since the collision block 200 protrudes from the surface of the mounting shell 100, when the door rotates to the position of the bumper, the door body will abut against the collision block 200 instead of directly hitting the mounting shell 100, thereby preventing the mounting shell 100 from being damaged.

[0032] Furthermore, the mounting notch 110 has a bottom surface, and the bottom surface is provided with a mounting hole 120;

[0033] The collision block 200 is provided with a mounting groove 230 , and the mounting groove 230 is connected to the mounting hole 120 by screws or bolts.

[0034] Specifically, the mounting groove 230 on the collision block 200 runs through the side surface and the top surface of the collision block 200, which is convenient for inserting tools and provides convenience for maintenance and replacement.

[0035] Furthermore, the height of the collision block 200 is greater than the height of the installation notch 110 .

[0036] The height of the collision block 200 is greater than the height of the installation notch 110, so that the top of the collision block 200 can be higher than the top of the installation shell 100, so that when the door body rotates to this position, it will directly contact the collision block 200 instead of directly hitting the installation shell 100, avoiding damage to the installation shell 100.

[0037] Furthermore, the edge of the collision block 200 is located outside the installation notch 110 .

[0038] The edge of the collision block 200 is located on the outside of the installation notch 110, so that the collision block 200 has a certain protective effect on the installation shell 100. The impact from other objects can be blocked by the collision block 200, avoiding the side of the installation shell 100 from being hit by other objects, thereby extending the service life of the installation shell 100.

[0039] Furthermore, the cross-sectional area of ​​the collision block 200 gradually increases from top to bottom along the height direction of the installation notch 110 .

[0040] The cross-section of the collision block 200 gradually increases from top to bottom, so that the area of ​​the bottom end of the collision block 200 that is in contact with the installation notch 110 is larger, which can make the connection between the collision block 200 and the installation shell 100 more stable; the area of ​​the end of the collision block 200 that contacts the door is smaller, which facilitates the deformation of the end under the pressure of the door to provide a buffering effect, thereby improving the user experience.

[0041] Furthermore, the collision block 200 includes a first side surface 210 and a second side surface 220 , wherein the first side surface 210 can abut against a side surface of the installation notch 110 , and the second side surface 220 is used to abut against a door, and the second side surface 220 is spherically arranged.

[0042] The second side surface 220 is spherical, so that when the second side surface 220 contacts the door body, as the door body is squeezed, the deformation of the spherical second side surface 220 becomes larger and larger, so that the force of its deformation becomes larger and larger, and then the reaction force on the door body becomes larger and larger. Therefore, the spherical second side surface 220 can not only play a buffering role on the door body, but also prevent the collision block 200 from excessively deforming and causing the door body to hit the installation shell 100, which eventually causes the installation shell 100 to be damaged.

[0043] Furthermore, the installation housing 100 is provided with a mounting column 130 , and the mounting column 130 is used to install the installation housing 100 on a wall.

[0044] Furthermore, the collision block 200 is located on a side of the mounting housing 100 facing the rotation axis of the door.

[0045] It should be noted that the anti-collision device in the present application is suitable for doors that rotate to open and close. This type of door rotates around a shaft to achieve opening and closing, and the position of the shaft is generally in the same plane as the wall on which the anti-collision device is installed. This causes the door to collide with the anti-collision device before it rotates to 90° from a closed state. It can be seen that the surface of the door body and the anti-collision device are not completely perpendicular, but have an angle less than 90°.

[0046] Based on this, the collision block 200 of the present application is arranged at an angle above the mounting shell 100 and on the side facing the rotating shaft, so that the bottom and side surfaces of the mounting notch 110 can be subjected to force at the same time, making the force at various positions of the mounting shell 100 more uniform, thereby reducing the force at a single position and extending the service life.

[0047] Furthermore, the mounting shell 100 is made of metal or plastic, and the collision block 200 is made of rubber.

[0048] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0049] In addition, in the present invention, the descriptions such as "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0050] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
