In modern buildings, elevators are widely used, so the demand for elevators is increasing, and the requirements for installation and reliability are also getting higher and higher. They require easy installation and easy adjustment. The elevator hall door requires a slider when in use, which can help the elevator door slide smoothly during opening and closing.

[0003] The existing door sliders still have some shortcomings in actual use:

[0004] In order to ensure the smooth operation of the elevator hall door, the slider is mostly made of plastic or rubber. In addition, for some elevator hall sliders, in order to ensure the smooth installation of the slider and prevent the slider from falling off at the connection between the slider and the hall door, the bottom of the slider is mostly closed, which makes it inconvenient to remove the slider. At the same time, the slider is made of plastic or rubber, and it is easy to cause the slider to deform or break when it is forcibly removed. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the bottom of the door slider is mostly closed, which makes it inconvenient to remove the slider, and the slider is made of plastic, which is easy to deform or break when the slider is forcibly removed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The door slider comprises a hall door, and a slider body is embedded in the hall door, the slider body consists of a slide seat, two connecting blocks and two clamping plates, and the connecting blocks are fixedly connected to the top two sides of the slide seat, and the two clamping plates are respectively fixedly connected to the top of the connecting blocks, and the two clamping plates can fit with the connection of the hall door; support plates are provided on both sides of the slide seat, and the tops of the two support plates are inclined to both sides, and the support plates are inclined to both sides to support in the hall door track.

[0008] In a possible design, a top block is provided on the top of the clamping plate to increase the contact area of ​​the top of the clamping plate, and a resistance block is provided on the side away from each other of the two top blocks, and a reinforcing rib is provided on the side away from each other of the two clamping plates, and the resistance block and the reinforcing rib protrude from one side of the clamping plate, and a slot is formed on one side of the clamping plate through the resistance block and the reinforcing rib, and the slot and the hall door are engaged to limit the position.

[0009] In a possible design, both sides of the slide seat are provided with a clearance groove, and the opening of the side where the two clearance grooves are close to each other is smaller than the opening of the side where they are far away from each other. An arc groove is provided at the bottom of the clearance groove, and the support plate is fixedly connected to one end of the arc groove. The arc groove can assist the support plate in folding, and the clearance groove can provide a clearance space for the folding of the support plate.

[0010] In a possible design, a U-shaped groove is provided at the bottom of the slide seat, which can not only slide in cooperation with the slide rail, but also guide its sliding. At the same time, the U-shaped groove can also support the cooperation between the slide seat and the hanging rail.

[0011] In a possible design, triangular grooves are provided on both sides of the slide seat, through grooves are provided in the two connecting blocks, and the through grooves, triangular grooves and U-shaped grooves are connected. The two sides of the U-shaped groove can be connected with the two triangular grooves respectively. The triangular grooves can be sleeved on the connection of the hall door to support the entire slide block, and the two triangular grooves can also be used to limit the slide block on the left and right sides.

[0012] In a possible design, the slider body is made of TPFE material, which has good wear resistance.

[0013] In a possible design, a reinforcing block is provided on each side of the two top blocks that are close to each other, so as to facilitate squeezing the two clamping plates inwards and release the clamping groove from the hall door.

[0014] In a possible design, arc corners are provided at the connection points between the two connection blocks and the sliding seat on the side close to each other, and the arc corners can facilitate the clamping plate to bend inwardly.

[0015] In the present application, a slider body is included in the hall door. The assembly consists of a slide seat, two connecting blocks and two clamping plates to ensure the stability and wear resistance of the slider body during the opening and closing of the elevator door. First, the slider body is guided and matched with the slide rail through the U-shaped groove of its bottom structure to achieve a smooth sliding action. At the same time, the U-shaped groove also plays a supporting role to ensure a close fit between the door slider and the hanging rail. Secondly, the support plate parts on both sides of the slider body are designed with an inclined angle. This design enables it to be effectively supported in the hall door track to prevent the door slider from shaking or deviating during the sliding process. The door slider is designed to move in a manner that allows it to move freely, and a slot structure is formed on one side of the clip plate through the top block and the reinforcement ribs, which engages with the hall door and effectively limits the movement range of the door slider to ensure that it runs within the predetermined track. In addition, the door slider is made of TPFE material, which has good wear resistance and can extend the service life of the door slider. Finally, the design of the door slider also takes into account the characteristics of easy installation and disassembly.

[0016] In the utility model, the top of the door slider and the clamping plate part are provided with a top block, a resistance block and a reinforcing rib. Through the combination of these structures, a clamping groove is formed to engage with the hall door, which effectively enhances the structural strength of the door slider and ensures its quality of use. It also effectively limits the moving range of the slider body and ensures its stable operation within the predetermined track. This limit design not only improves the safety of elevator operation, but also reduces the risk of failure caused by displacement or falling off of the slider body.

[0017] In the utility model, the slider body is supported by an integrated molding method and is made of TPFE material, which has good wear resistance, which means that the slider body can maintain a good shape and function during long-term use, while also extending the service life. The improvement of wear resistance also reduces the noise and wear caused by friction, and improves the passenger experience;

[0018] In the utility model, the slider body achieves beneficial effects such as enhanced stability, significant limiting function, excellent wear resistance, convenient installation and disassembly, and reasonable structural design through its unique design, providing a strong guarantee for the safe and stable operation of the elevator.
