DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] Example:
[0024] See also Figure 1-Figure 6 , the utility model provides a technical solution:
[0025] A silent aluminum alloy door with an anti-pinch function comprises a door frame 1 and a door body 2, the door body 2 is hinged to the inner side of the door frame 1, hidden grooves 3 are provided at the upper and lower ends and the right side of the door frame 1, buffer plates 4 are movably installed on the inner sides of multiple groups of hidden grooves 3, buffer mechanisms 5 are fixedly installed on both ends of the multiple groups of buffer plates 4 located on the inner sides of the hidden grooves 3, a storage groove 6 is provided at the bottom end of the inner side of the door body 2, a blocking rod 7 is rotatably connected to the inner side of the storage groove 6, a fixing column 8 is fixedly connected to the top of the blocking rod 7, and a fixing box 9 adapted for use with the fixing column 8 is fixedly installed inside the door body 2.
[0026] Firstly, the plurality of buffer plates 4 are all made of hard rubber plates, and the outer size of the plurality of buffer plates 4 is the same as the inner size of the hidden groove 3 . When the door body 2 is closed, the buffer plates 4 are located at the inner side of the hidden groove 3 .
[0027] Furthermore, the buffer mechanism 5 includes a slide bar 501 fixedly connected to the two ends of the hidden groove 3, a slide sleeve 502 is slidably connected to the outer side of the slide bar 501, a first transmission rod 503 is installed between the slide sleeve 502 and the buffer plate 4, and the two ends of the first transmission rod 503 are rotatably connected to the slide sleeve 502 and the buffer plate 4 respectively, and a first buffer spring 504 is also sleeved on the outer side of the slide bar 501. When the door body 2 is closed, the buffer plate 4 is pressed and located on the inner side of the hidden groove 3, and the slide sleeve 502 is pushed under the transmission of the first transmission rod 503, so that the first buffer spring 504 is pressed and the first buffer spring 504 is pressed. 04 is squeezed and contracted, and when the door body 2 is opened, the first buffer spring 504 rebounds to push the buffer plate 4 out from the inner side of the hidden groove 3. When the door body 2 is suddenly closed quickly, the blocking rod 7 hits the buffer plate 4 to block it, thereby avoiding the door body 2 from being pinched due to rapid closing. At the same time, when the blocking rod 7 hits the buffer plate 4, the sliding sleeve 502 is pushed under the transmission of the first transmission rod 503. The first buffer spring 504 can buffer the impact force, thereby avoiding the door body 2 from colliding with the door frame 1 when closing quickly to generate collision noise and collision vibration loss.
[0028] Then, the blocking rod 7 is composed of a connecting tube 701 and a push rod 702. The push rod 702 is slidably connected to the inside of the connecting tube 701. One end of the push rod 702 located on the outside of the connecting tube 701 is fixedly connected to a rubber block 703. A second buffer spring 704 is movably installed inside the connecting tube 701. When the door body 2 is suddenly closed quickly, the connecting tube 701 and the push rod 702 are used to block the door body 2 from being pinched due to rapid closing. At the same time, when the push rod 702 hits the door frame 1, it will support the buffer plate 4. The impact force is buffered by the second buffer spring 704 inside the connecting tube 701, further avoiding collision noise and collision vibration loss caused by the collision of the door body 2 with the door frame 1 when the door body 2 is closed quickly.
[0029] Secondly, the upper and lower ends of the connecting tube 701 are rotatably connected to the inner side of the storage slot 6 through the rotating shaft 705, and the outer sides of the two sets of rotating shafts 705 are sleeved with torsion springs 706. When the door body 2 is closed, the connecting tube 701 is rotated into the inner side of the storage slot 6 so that the door body 2 can be used normally. After the door body 2 is opened, the fixing box 9 is first used to release the fixation of the fixing column 8, and the connecting tube 701 will be automatically rotated out from the inner side of the storage slot 6 under the action of the torsion spring 706.
[0030] Finally, a button 901 is slidably connected to the outer side of the fixed box 9, and one end of the button 901 located inside the fixed box 9 is fixedly connected to the first slider 902. The inner side of the first slider 902 is fixedly connected to the fixed box 9 through a return spring 903. A second slider 904 is slidably connected to the right end of the fixed box 9. A second transmission rod 905 is installed between the second slider 904 and the first slider 902, and the two ends of the second transmission rod 905 are rotatably connected to the second slider 904 and the first slider 902 respectively. The right side of the second slider 904 is slidably connected to the fixed box 9 through a fixed plug post 906, and both ends of the first slider 902 are slidably connected to the fixed box 9 through sliding posts 907. Dynamic connection, the interior of the fixing column 8 is provided with a fixing hole 908 adapted for use with the fixing plug column 906. When the blocking rod 7 is located on the inner side of the storage groove 6, the fixing plug column 906 is inserted into the fixing hole 908 inside the fixing column 8, thereby fixing the blocking rod 7 on the inner side of the storage groove 6. After the door body 2 is opened, pressing the button 901 drives the first slider 902 to slide stably under the connection of the sliding column 907, and then pulls the second slider 904 to move under the transmission of the second transmission rod 905, thereby pulling the fixing column 8 to retract into the interior of the fixing box 9, and then quickly releasing the fixation of the fixing column 8, so that the blocking rod 7 automatically pops out from the inner side of the storage groove 6.
[0031] In this embodiment, the implementation scenario is specifically as follows: after the door body 2 is opened, the button 901 is pressed to drive the first slider 902 to slide stably under the connection of the sliding column 907, and then the second slider 904 is pulled to move under the transmission of the second transmission rod 905, thereby pulling the fixing column 8 to retract into the interior of the fixing box 9, and then quickly releasing the fixation of the fixing column 8, so that the blocking rod 7 automatically pops out from the inner side of the storage groove 6, and when the door body 2 is opened, the first buffer spring 504 rebounds to push the buffer plate 4 out from the inner side of the hidden groove 3. When the door body 2 is suddenly and quickly closed, the blocking rod 7 hits the buffer plate 4 to block it, thereby preventing the door body 2 from being blocked. In order to prevent injuries caused by rapid closing, when the blocking rod 7 hits the buffer plate 4, the sliding sleeve 502 will be pushed under the transmission of the first transmission rod 503, and the impact force can be buffered by the first buffer spring 504. When the top rod 702 hits the door frame 1, it will support the buffer plate 4, and the impact force is further buffered by the second buffer spring 704 inside the connecting tube 701. The whole operation process is simple and convenient. Compared with the existing aluminum alloy door, the utility model avoids the situation of pinching caused by rapid closing of the door body 2 through design, and at the same time avoids the collision noise and collision vibration loss caused by the collision of the door body 2 with the door frame 1 when it is closed quickly.
