Description

Technical Field

[0001] This utility model relates to the field of elevator handrail technology, and in particular to a handrail belt docking structure. Background Technology

[0002] Elevator handrails are an important component of elevators, primarily used to ensure passenger safety and stability. The connection structure of the handrail is a key part of ensuring its stable operation and safety, especially in escalators where the handrail belt needs to move synchronously with the steps while maintaining sufficient strength and durability. During use, the two ends of the handrail belt need to be joined together. However, in existing technologies, during this joining process, the steel wires inside the handrail belt can warp and pierce through, leading to damage. Summary of the Invention

[0003] According to an embodiment of the present utility model, a handrail belt docking structure is provided, comprising: a handrail belt, steel wire, reinforcing mesh, and a filler layer;

[0004] The handrail belt has a reinforcing groove, and the steel wire is placed in the reinforcing groove. The two ends of the handrail belt are the beginning end and the end end, respectively.

[0005] Both the first and last ends are provided with cutting grooves. The bottom of the cutting grooves reveals the reinforcing grooves and the steel wires inside. The steel wires at the first end are connected to the steel wires at the last end. The reinforcing mesh covers the connection point of the steel wires. The cutting grooves at the first and last ends are filled with a filler layer.

[0006] Furthermore, the handrail is provided with a sliding layer, and a sliding strip is provided at the connection between the sliding layers at the first and last ends.

[0007] Furthermore, the sliding strip is made of the same material as the sliding layer.

[0008] Furthermore, the steel wire includes: a central wire and side wires;

[0009] The side wires are located on both sides of the middle wires, and there are eight middle wires and five side wires.

[0010] According to an embodiment of the present invention, a handrail belt docking structure is provided. The first end and the last end are cut to form a cutting groove, exposing the steel wires at the first end and the last end. Then, the steel wires at the first end and the last end are docked, and a reinforcing mesh is placed over the docking point of the steel wires. This can effectively prevent the steel wires from warping and avoid the steel wires from penetrating the handrail belt or filler layer, while also increasing the structural strength of the handrail belt connection.

[0011] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0017] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0018] like Figs. 1-4 As shown, an embodiment of the present invention provides a handrail belt docking structure, comprising: a handrail belt, a steel wire 3, a reinforcing mesh 4, and a filler layer 5;

[0019] The handrail belt has a reinforcing groove, the steel wire 3 is placed in the reinforcing groove, and the two ends of the handrail belt are the first end 1 and the last end 2, respectively.

[0020] Both the first end 1 and the last end 2 are provided with cutting grooves. The bottom of the cutting grooves can see the reinforcing grooves and the steel wires 3 inside the reinforcing grooves. The steel wires 3 on the first end 1 are connected to the steel wires 3 on the last end 2. The reinforcing mesh 4 covers the connection of the steel wires 3. The cutting grooves on the first end 1 and the last end 2 are filled by the filler layer 5.

[0021] This application first cuts the first end 1 and the last end 2 to form a cutting groove, exposing the steel wire 3 of the first end 1 and the last end 2. Then, the steel wire 3 of the first end 1 and the last end 2 are joined together, and the reinforcing mesh 4 is covered at the joint of the steel wire 3. This can effectively prevent the steel wire 3 from sticking up and avoid the steel wire 3 from penetrating the handrail belt or filler layer 5 when the first end 1 and the last end 2 are spliced. At the same time, it increases the structural strength of the handrail belt connection.

[0022] In this embodiment, when the first end 1 and the last end 2 of the handrail belt are joined together, there is a gap of 0mm to 10mm between the first end 1 and the last end 2, which can be filled with rubber. After the handrail belt is cut to form a cutting groove, the cut part can be attached to the handrail belt or cut off from the handrail belt, as long as the cut part can be used to fill the cutting groove.

[0023] The handrail is provided with a sliding layer 7, and a sliding strip 6 is provided at the connection between the sliding layer 7 at the first end 1 and the last end 2. The sliding strip 6 is made of the same material as the sliding layer 7.

[0024] In this embodiment, the two ends of the sliding strip 6 are inclined to prevent edge cracking and enhance strength. By covering the connection between the sliding layer 7 on the first end 1 and the last end 2 with the sliding strip 6, the performance of the splicing point is ensured to be unaffected.

[0025] The steel wire 3 includes: a central wire and side wires; the side wires are located on both sides of the central wire, there are eight central wires and five side wires.

[0026] In other embodiments, the steel wire 3 on the first end 1 is U-shaped, the steel wire 3 on the tail end 2 is convex, the middle wire at the tail end 2 extends from the end of the tail end 2, the middle wire is set corresponding to the middle wire on the first end 1 and is located in the reinforcing groove on the first end 1.

[0027] Cut off part of the middle wire on the first end 1 to make the steel wire 3 of the first end 1 concave. Cut off part of the handrail and sliding layer 7 of the tail end 2 to expose part of the steel wire 3. Then cut off the side wires of the steel wire 3 to make the steel wire 3 convex. Place the middle wire of the tail end 2 into the reinforcing groove of the middle wire on the first end 1. Splice the first end 1 and the tail end 2. Cover the joint of the steel wire 3 with the reinforcing mesh 4. Then cover the cutting groove on the first end 1 and the tail end 2 with the filling layer 5. Heat the filling layer 5 to connect and fix the first end 1 and the tail end 2.

[0028] Above, refer to Figs. 1-4 This application describes a handrail belt docking structure according to an embodiment of the present invention. First, the first end 1 and the last end 2 are cut to form a cutting groove, exposing the steel wires 3 of the first end 1 and the last end 2. Then, the steel wires 3 of the first end 1 and the last end 2 are docked. The reinforcing mesh 4 is covered at the docking point of the steel wires 3, which can effectively prevent the steel wires 3 from sticking up and avoid the steel wires 3 from penetrating the handrail belt or the filler layer 5.
