AI Technical Summary
Existing glass doors are prone to strong impacts due to inertia when closing, causing the door leaf to collide with the door frame, resulting in glass breakage or damage. Furthermore, existing buffering technologies are difficult to effectively control the closing speed and force, increasing maintenance costs and safety risks.
A camshaft buffer structure is designed to slow down the rotation speed of the rotating shaft by cooperating with the buffer spring, thereby preventing the glass door from suddenly closing or hitting the door frame. The structure includes a combination of a buffer connector, a buffer spring, and a spring kit. The buffer spring is compressed by the abutting movement of the limit clip and the spring kit, thus slowing down the rotation speed of the rotating shaft.

Technical Field
[0001] This utility model belongs to the technical field of glass door components, specifically relating to a camshaft buffer structure. Background Technology
[0002] In modern architecture and interior design, glass doors are widely popular due to their unique aesthetics and practicality. These doors effectively enhance the light transmission and openness of a space, and are widely used in commercial buildings, office buildings, hotels, and residences. However, glass doors often face a series of technical challenges during use, especially during opening and closing. Due to their own weight and inertia, the door leaf can generate a strong impact when closing rapidly, causing a collision between the door leaf and the door frame, which can lead to glass breakage or frame damage. This not only increases subsequent maintenance and replacement costs but may also pose a serious threat to user safety, especially in high-traffic public places.
[0003] Currently, most existing buffering technologies rely on mechanical dampers. While these can slow down the closing speed of doors to some extent, they often cannot effectively control the speed and force during the closing process in practical applications. This results in the door still generating a significant impact force when closing, making it difficult to completely solve the impact and vibration problems faced by glass doors. Furthermore, their performance may degrade after a period of use, further affecting their effectiveness.
[0004] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

DETAILED DESCRIPTION
[0018] As shown in Figs. 1 to 4 A camshaft buffering structure, comprising a mounting frame 10, a buffering device 20 and a rotating shaft 30, wherein the surface of the mounting frame 10 is provided with a mounting slot 11, the buffering device 20 and the rotating shaft 30 are respectively mounted in the mounting slot 11, and the rotating shaft 30 is in abutting connection with the buffering device 20. In use, when the rotating shaft 30 rotates, the rotating shaft 30 can push the buffering device 20 to contract, so as to avoid the sudden collision of the glass door due to inertia when the glass door is opened or closed, and reduce the risk of breaking or damaging the glass door.
[0019] In specific implementation, the buffering device 20 comprises a buffering connector 21, a buffering spring 22 and a spring sleeve 23, wherein the buffering spring 22 is connected between the buffering connector 21 and the spring sleeve 23, the middle part of the rotating shaft 30 is provided with a limiting clamping part 31, and the spring sleeve 23 is in abutting connection with the limiting clamping part 31. In use, when the rotating shaft 30 rotates, the limiting clamping part 31 pushes the spring sleeve 23 to move towards the buffering connector 21, and the relative movement between the spring sleeve 23 and the buffering connector 21 causes the buffering spring 22 to be compressed. Through the compression and rebound of the buffering spring 22, the rotating speed of the rotating shaft 30 is slowed down, which helps to avoid the sudden closing or impact of the glass door to the door frame due to inertia. This buffering structure not only reduces the damage risk to the glass door itself, but also reduces the safety hidden danger that may be caused to the user. Through reducing the impact and vibration, this buffering structure helps to prolong the service life of the glass door and its related components.
[0020] In specific implementation, the front part of the buffering connector 21 is provided with a spring joint 211, the inside of the spring sleeve 23 is concavely provided with a spring joint groove 231, the rear end of the buffering spring 22 is weldedly connected to the spring joint 211, and the front end of the buffering spring 22 is connected in the spring joint groove 231, so that the buffering spring 22 is connected between the buffering connector 21 and the spring sleeve 23. The structure is simple and convenient to install.
[0021] The first embodiment of the rotating shaft 30 is as follows:
[0022] The limiting clamping part 31 is concavely provided with a limiting recess 311, the middle part of the limiting recess 311 is protrudingly provided with a limiting protruding block 312, the limiting protruding block 312 is in abutting connection with the spring sleeve 23, the front part of the limiting protruding block 312 is provided with a circular-arc-shaped limiting arc corner 313, when the rotating shaft 30 rotates, the limiting protruding block 312 moves along the spring sleeve 23 through the limiting arc corner 313, so that the limiting protruding block 312 pushes the spring sleeve 23 to move and compresses the buffering spring 22, and the rotating speed of the rotating shaft 30 is slowed down, thereby reducing the risk of breaking or damaging the glass door.
[0023] The second embodiment of the rotating shaft 30 is as follows:
[0024] The limiting card part 31 is concave and has a limiting recess 311. The limiting recess 311 has a plurality of limiting card surfaces 314. The limiting card surfaces 314 abut against the spring sleeve 23. The limiting card surfaces 314 are connected by arc-shaped limiting edge corners 315. When the rotating shaft 30 rotates, the limiting card surfaces 314 move along the spring sleeve 23 through the limiting edge corners 315. The limiting card surfaces 314 push the spring sleeve 23 to compress the buffer spring 22. The rotating speed of the rotating shaft 30 is slowed down. The risk of breaking or damaging the glass door is reduced.
[0025] In summary, the surface of the mounting frame 10 is provided with a mounting slot 11. The buffer device 20 and the rotating shaft 30 are mounted in the mounting slot 11. The buffer device 20 includes a buffer connecting piece 21, a buffer spring 22, and a spring sleeve 23.

The camshaft buffer structure of the utility model can slow down the rotating speed of the rotating shaft through the cooperation between the buffer spring and the rotating shaft. This helps to avoid the sudden closing or impact of the glass door on the door frame due to inertia, reduces the risk of damage, prolongs the service life by reducing the impact and vibration.
