Description

Technical Field

[0001] The utility model relates to the field of doors, in particular to a sealing leather strip structure of an airtight door. Background Art

[0002] Sealing strips are widely used in door products. The functions of sealing strips are: first, they play a sealing and isolation role; second, they avoid rigid collision between the door body and the door frame, protecting the door from damage; third, they reduce abnormal noise caused by closing the door.

[0003] Publication No. CN117841633A provides a lower sealing strip structure, a side door decorative panel and a car. The patent has the following defects: first, after long-term use, the elasticity of the sealing strip will decrease due to aging, and the aged sealing strip needs to be replaced. The patent uses buckles to connect the sealing strips, and the buckles need to be removed in advance before removing the sealing strips. Therefore, the sealing strip structure provided by the patent is inconvenient to disassemble; second, when the sealing strip is in an extruded state, there is an uneven extrusion force. After long-term use, there are differences in the resilience of the leather strip, and the sealing performance is reduced; third, since the position of the buckle determines the installation position of the sealing strip, when the buckle is not installed accurately, the installation position of the sealing strip also has deviations. Therefore, the installation accuracy of the sealing strip provided by the patent is not high enough, and there is a certain installation deviation, which affects the sealing effect. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a novel leather strip structure for sliding doors. When the leather strip is in an extruded state, the extrusion force is uniform. After long-term use, there is no difference in the rebound force of each position of the leather strip, and the sealing performance is good.

[0005] The scheme is as follows: A leather strip structure for a sliding door, including a leather strip body 1 and a profile body 2, the leather strip body 1 including an arc surface 3 and a connecting surface 4, the arc surface 3 having a cross-section in the shape of an arc and connected to the connecting surface 4, the arc surface 3 and the connecting surface 4 enclosing an extrusion cavity 17; the two ends of the arc surface 3 are bent inward and extended to form a first extension surface 5 and a second extension surface 6, the first extension surface 5 and the second extension surface 6 are parallel to the connecting surface 4, the first extension surface 5 and the second extension surface 6 respectively form a first groove 7 and a second groove 8 with the connecting surface 4, and a profile mounting groove 9 is formed between the first extension surface 5 and the second extension surface 6.

[0006] Preferably, the profile body 2 includes a mounting surface 10, a first supporting surface 11, and a second supporting surface 12, and the mounting surface 10, the first supporting surface 11, and the second supporting surface 12 form a screw mounting groove 15, and the first supporting surface 11 and the second supporting surface 12 are respectively bent outward and extended to form a third extension surface 13 and a fourth extension surface 14; the third extension surface 13 is embedded in the first groove 7, and the fourth extension surface 14 is embedded in the second groove 8.

[0007] Preferably, the distance between the first extension surface 5 and the second extension surface 6 is slightly smaller than the distance between the first supporting surface 11 and the second supporting surface 12 .

[0008] Preferably, the profile body 2 is connected to the sliding door frame via screws 16 .

[0009] The beneficial effects of the utility model are as follows: the strap structure of the utility model is used for sealing the sliding door frame. When the sliding door is closed, the arc surfaces of the strap structure are squeezed to form a good seal. The strap is made of rubber material, and the extrusion cavity makes the strap more elastic, thereby enhancing the sealing performance of the sliding door. The sliding door is commonly used in hospital operating rooms, radiology rooms, food workshops, pharmaceutical workshops, and other places with high sealing requirements. The strap locates the installation position of the strap according to the trajectory of the profile body, and uses the structural form of the profile body to determine the structural form of the strap. When the strap is in an extruded state, the extrusion force is uniform, which greatly improves the sealing performance of the strap. In addition, the first groove and the second groove of the strap body can be directly embedded or inserted into the third extension surface and the fourth extension surface of the profile body, so it is very convenient to disassemble and assemble the strap, which is convenient for daily replacement, cleaning and maintenance of the strap.
