Description

Technical Field

[0001] The utility model relates to the technical field of anti-collision strips, and particularly relates to an anti-collision strip capable of adjusting the bearing pressure. Background Art

[0002] Anti-collision strips are often used on sliding doors and windows. The anti-collision strips achieve shock absorption and buffering when the doors and windows are closed through the elasticity of the material itself and the buffer cavities inside. In actual use, different doors and windows have different weights and different kinetic energies when closed. However, the buffering ability of ordinary anti-collision strips is fixed. When the weight of the doors and windows does not match the bearing pressure of the anti-collision strips, the anti-collision strips will be directly flattened or have a small deformation, resulting in a poor buffering effect. Content of the Utility Model

[0003] In order to solve the above technical deficiencies, the utility model provides an anti-collision strip capable of adjusting the bearing pressure, which can adjust the bearing pressure of the anti-collision strip to adapt to doors and windows of different weights.

[0004] The utility model discloses an anti-collision strip capable of adjusting the bearing pressure, which comprises a long strip-shaped base. An arc-shaped buffer structure is arranged on the front surface of the long strip-shaped base. The long strip-shaped base and the arc-shaped buffer structure form a buffer cavity. Both ends of the buffer cavity are sealed by a first plug. Through holes communicating with the buffer cavity are evenly arranged on the back surface of the long strip-shaped base. Counterbores corresponding to the through holes are arranged at the positions of the side surface of the long strip-shaped base. The counterbores are communicated with the through holes. A second plug is arranged on the counterbore. A paste layer is arranged on the back surface of the long strip-shaped base. The paste layer seals the end of the through hole close to the back surface of the long strip-shaped base.

[0005] When the above technical solution is used, the back surface of the long strip-shaped base is bonded to the doors and windows through the paste layer. When closing the doors and windows, buffering is carried out through the arc-shaped buffer structure. During the buffering process, the arc-shaped buffer structure is pressed. At this time, since both ends of the buffer cavity are sealed by the first plug, it should be noted that the first plug is made of an elastic material, and the paste layer seals the end of the through hole close to the back surface of the long strip-shaped base. At the same time, a second plug is arranged on the counterbore. Therefore, the air pressure in the buffer cavity becomes larger, further playing a buffering role. At this time, the bearing pressure of the anti-collision strip reaches the maximum. When the weight of the doors and windows is small and the required bearing pressure of the anti-collision strip is small, some of the second plugs can be removed, so that the inside of the buffer cavity communicates with the outside. It should be noted here that the number of removed second plugs should be related to the weight of the doors and windows. The more second plugs are removed, the faster the air in the buffer cavity can be discharged when the arc-shaped buffer structure is pressed, so that the bearing pressure of the anti-collision strip is smaller, thus adapting to lighter doors and windows.

[0006] Furthermore, internal threads are arranged at the ends of the counterbores, external threads are arranged on the second plugs, and the second plugs are screwed with the counterbores, so that the connection between the second plugs and the counterbores is more firm through screwing.

[0007] An anti-collision strip capable of adjusting the bearing pressure obtained by the present utility model has the beneficial effect that through the arc-shaped buffer structure, the anti-collision strip has a certain bearing capacity. At the same time, by adjusting the number of removed second plugs, the communication degree between the buffer cavity and the outside is adjusted, so as to adjust the discharge speed of the air in the buffer cavity when the arc-shaped buffer structure is pressed, thereby changing the bearing capacity of the anti-collision strip to adapt to doors and windows of different weights.

[0011] In order to further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following combines the drawings and preferred embodiments to detail the specific implementation manners, structures, features and their effects according to the present utility model as follows.

[0012] Embodiment 1:

[0013] As Figures 1 to 3 shown, the present utility model discloses an anti-collision strip capable of adjusting the bearing pressure, including a long strip-shaped base 2. An arc-shaped buffer structure 4 is arranged on the front surface of the long strip-shaped base 2. A buffer cavity 9 is formed between the long strip-shaped base 2 and the arc-shaped buffer structure 4. Both ends of the buffer cavity 9 are sealed by a first plug 5. Through holes 6 communicating with the buffer cavity 9 are evenly arranged on the back surface of the long strip-shaped base 2. Counterbores 7 corresponding to the positions of the through holes 6 are arranged on the side surface of the long strip-shaped base 2. The counterbores 7 communicate with the through holes 6. Internal threads 8 are arranged at the ends of the counterbores 7. Second plugs 3 are arranged on the counterbores 7. External threads are arranged on the second plugs 3. The second plugs 3 are screwed with the counterbores 7. A paste layer 1 is arranged on the back surface of the long strip-shaped base 2. The paste layer 1 seals the end of the through hole 6 close to the back surface of the long strip-shaped base 2.

[0014] When the above technical solution is in use, the back of the long strip base 2 is bonded to the doors and windows through the adhesive layer 1. When closing the doors and windows, buffering is carried out through the arc buffering structure 4. During the buffering process, the arc buffering structure 4 is pressed. At this time, since both ends of the buffer cavity 9 are sealed by the first plug 5, and the adhesive layer 1 seals the end of the through hole 6 close to the back of the long strip base 2, and at the same time, the second plug 3 is arranged on the counterbore 7, the air pressure in the buffer cavity 9 becomes larger, further playing a buffering role. At this time, the bearing pressure of the anti-collision strip reaches the maximum. When the weight of the doors and windows is small and the required bearing pressure of the anti-collision strip is small, some of the second plugs 3 can be removed, so that the inside of the buffer cavity 9 is communicated with the outside. It should be noted here that the number of the second plugs 3 removed should be related to the weight of the doors and windows. The more the second plugs 3 are removed, the faster the air in the buffer cavity 9 can be discharged when the arc buffering structure 4 is pressed, so that the bearing pressure of the anti-collision strip is smaller, so as to adapt to lighter doors and windows.
