Description

Technical Field

[0001] This utility model relates to the field of handrail installation technology, and in particular to a handrail connecting mechanism. Background Technology

[0002] Among various facilities, the connection of handrails is crucial, as the connection method directly affects the handrail's performance, safety, and aesthetics. Currently, common handrail connection methods include screw connections, expansion bolt connections, and angle bracket connections. Taking bolt connections as an example, when installing handrails, they are usually connected directly to the mounting holes on the handrail, or the handrail is fixed by passing through bolts to connect with other components. However, because handrails are frequently subjected to dynamic loads applied by the human body during daily use, the bolts are under repeated stress for a long time. Long-term friction and vibration will also gradually increase the gap between the bolt and the mounting hole. When people use the handrail, they will clearly feel that the handrail is shaking more, which not only reduces the comfort of use, but also further accelerates the wear of other components.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0019] Reference Figures 1-4 As shown, an armrest connection mechanism includes a hollow armrest frame 1 and a hollow support tube 2. The support tube 2 supports the armrest frame 1. A first inner core 11 is movably installed inside the armrest frame 1. During installation, the first inner core 11 can be installed to a specific installation position of the armrest frame 1 through an opening at one end. A second inner core 21 is movably installed inside the support tube 2 and is connected to the support tube 2 by a first fixing bolt 22. A flange 3 is also installed at the end of the support tube 2 away from the armrest frame 1 and at the end of the armrest frame 1, for connecting the support tube 2 and the armrest frame 1 to other installation parts. For example, when the armrest frame 1 is installed on a seat, it is connected to the seat plate through the flange 3 to achieve the installation of the armrest frame 1. A third inner core 31 is provided inside the support tube 2 and the handrail frame 1. The third inner core 31 is connected to the support tube 2 and the handrail frame 1 by a second fixing bolt 32. A positioning bolt 4 is also included. Positioning holes that cooperate with the positioning bolt 4 are provided on the first inner core 11, the second inner core 21 and the third inner core 31. After the second inner core 21 is connected to the support tube 2 and the third inner core 31 is connected to the other end of the support tube 2 or the end of the handrail frame 1, the positioning bolt 4 passes through the second inner core 21 and the flange 3 to realize the connection between the second inner core 21 and the first inner core 11 and between the flange 3 and the third inner core 31. This makes the handrail frame 1, the support tube 2 and the flange 3 form a stable connection system, reducing the risk of loosening caused by external forces during use and ensuring the safe use of the handrail.

[0020] Reference Figure 4As shown, furthermore, a bracket connector 5 is provided between the bracket tube 2 and the handrail frame 1. The bracket connector 5 has a through hole 51 for the positioning bolt 4 to pass through, and the bracket connector 5 is connected to the first inner core 11 by a third fixing bolt 52. The bracket connector 5 can fit against the contact surface of the handrail frame 1. For example, when the surface of the handrail frame 1 is a smooth arc, the end face of the bracket connector 5 is a corresponding smooth arc, ensuring that the bracket connector 5 and the handrail frame 1 can fit tightly together. The other end of the bracket connector 5 can match the end shape of the bracket tube 2. To achieve a stable connection between the two, during installation, the third fixing bolt 52 is first passed through the bracket connector 5 and then connected to the first inner core 11, fixing the bracket connector 5 to the handrail frame 1. Then, the positioning bolt 4 passes through the second inner core 21 and the bracket connector 5 in sequence and is then connected to the first inner core 11. This increases the number of connection points between the bracket connector 5 and the bracket tube 2, distributing the force and making the connection between the bracket tube 2 and the handrail frame 1 more stable, effectively avoiding the loosening problem caused by single-point force in screw connections.

[0021] Reference Figures 1-4 As shown, further, when the positioning bolt 4 connects the second inner core 21 to the first inner core 11, and then the bracket tube 2 is sleeved on the outside of the second inner core 21 and comes into contact with the bracket connector 5, the first fixing bolt 22 can be threaded into the through hole 51 of the second inner core 21. When the positioning bolt 4 connects the flange 3 to the third inner core 31, and the third inner core 31 is installed in the other end of the bracket tube 2 or the end of the handrail frame 1, so that the flange 3 comes into contact with its end, the second fixing bolt 32 can be threaded into the through hole 51 of the third inner core 31, thereby facilitating the installation of the first fixing bolt 22 and the second fixing bolt 32.

[0022] This also includes a cover plate 6, which is installed on the support tube 2 to cover the first fixing bolt 22 and the second fixing bolt 32. When covering the first fixing bolt 22, the cover plate 6 can be first placed on the support tube 2. After the support tube 2 is connected to the handrail frame 1, the cover plate 6 on the support tube 2 is connected to the support connector 5 by means of snap-fit ​​connection, thereby covering the first fixing bolt 22. When covering the second fixing bolt 32, the cover plate 6 can be first placed on the support tube 2 or the handrail frame 1. After the flange 3 is installed on the support tube 2 or the handrail frame 1, the cover plate 6 is connected to the flange 3 by means of snap-fit ​​connection. It should be noted that the cover plate 6 connected to the flange 3 and the cover plate 6 connected to the support connector 5 may have different shapes and sizes, as long as they can be matched and connected with the flange 3 or the support connector 5. The main purpose is to cover the first fixing bolt 22 and the second fixing bolt 32, making their appearance more aesthetically pleasing.

[0023] Reference Figure 3 As shown, further, the guide members 7 arranged axially on the outer walls of the first inner core 11, the second inner core 21, and the third inner core 31 are equipped with auxiliary parts that cooperate with the guide members 7 in the support tube 2 or the handrail frame 1. For example, the guide member 7 is a sliding groove, and the auxiliary part can be a sliding rail that slides with it, so as to guide the first inner core 11, the second inner core 21, or the third inner core 31 in the handrail frame 1 and the support tube 2, so that they will not rotate at will, and ensure that the first fixing bolt 22, the second fixing bolt 32, the third fixing bolt 52, and the positioning bolt 4 can be accurately threaded to their holes.

[0024] Furthermore, the first inner core 11, the second inner core 21, and the third inner core 31 are all made of high-strength aluminum alloy, which is lightweight, high-strength, and corrosion-resistant. This ensures the stability of the connection structure while extending the overall service life of the handrail.
