Description

Technical Field

[0001] The invention relates to an electric telescopic door, in particular to a trackless electric sliding door with a deviation correcting device. Background Art

[0002] At present, due to the characteristics of beautiful and exquisite electric retractable door series products and easy opening and closing, they have been widely used in the gates of large courtyards of government agencies, colleges, factories and residential communities, and with the rapid development of social and economic construction, the market demand is growing.

[0003] With the advancement of technology, electric telescopic doors have evolved into an electric sliding door.

[0004] The sliding doors currently on the market have their own shortcomings: 1. Sliding doors need to be installed against the wall with limit cards, which clamp them in place. The paint on the door surface is prone to falling off after repeated friction with the limit cards, causing corrosion and rust on the door material, greatly shortening the life of the door. 3. Sliding doors are equipped with rollers at the bottom, and embedded guide rails are installed on the corresponding parts of the ground for guidance. Since the rollers are fixed in a vertical position, in order to ensure that the embedded guide rails have appropriate contact with the rollers, the embedded guide rails must be aligned before embedding to ensure that their upper surfaces are parallel to the horizontal plane. However, the embedded guide rails on the ground will quickly wear, age, and deform after long-term rolling by pedestrians and vehicles, affecting the normal operation of the door. 4. There is also a type of sliding door whose overall structure is relatively easy to produce and install, but its door row traction device cannot achieve a good deviation correction function, the maintenance cost is high, and it is in urgent need of improvement. The following patent solutions of the existing technology can serve as representatives of the sliding door with the fourth defect.

[0005] Prior art: "A Corrective Sliding Door" (Publication No.: CN209413832U), Publication Date: September 20, 2019. This prior art discloses a corrective sliding door, comprising a door body and a magnetic track arranged in the forward direction of the door body; a column is provided at the front end of the door body, the column being rotatable relative to the door body; a running mechanism is provided on the column; the running mechanism includes a pair of motors and rollers respectively connected to the pair of motors; the rollers are respectively located on both sides of the door body; a probe is provided on the door body that can sense the magnetic track and thus detect whether the door body has deviated from the track; the door body is also provided with a control device that controls the start and stop of the motor to correct the door body; the probe is connected to the control device. This prior art realizes that by providing a door row tractor on the door body, the section sliding door drive system (head) pulls the door body to open and close normally along the specified route, and does not deviate significantly from the route. The biggest drawback of this existing technology is that the cross-section of the connecting shaft of the door row traction device is rectangular. During the actual use of the sliding door, the connecting shaft with a rectangular cross-section is very easy to wear. Once worn, the correction effect of the door row traction device is greatly reduced, which ultimately leads to frequent maintenance.

[0006] The present invention is an improvement directed to this type of sliding door. Summary of the Invention

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] [Example 1]

[0026] like Figure 1The figure shows the overall structure diagram of the telescopic door of the present embodiment 1 (three door rows). The trackless electric sliding door with a correcting device in the present embodiment includes an electromechanical door head 1, a door body 2 connected to the electromechanical door head 1, the door body 2 is composed of a plurality of door rows, and running wheels 3 are installed under the electromechanical door head 1 and the door body 2. The door rows are connected to their adjacent door rows and move relative to each other. The present embodiment includes a first door row 21, a second door row 22, and a third door row 23. The door rows are parallel to each other and are no longer on the same plane. The door rows are connected to each other in turn by rollers and chains; the correcting device 4 is composed of a first assembly 41, a second assembly 42, a first side wing 43, a second side wing 44, a pin 45 and a connecting shaft 49. The pin 45 also includes a nut 46. The cross section of the connecting shaft 49 is a runway circle. The first assembly 41 and The first side wing 43 is of integrated design, and the second assembly 42 and the second side wing 44 are also of integrated design. The first assembly 41 and the second assembly 42 are provided with holes with a runway circle cross section, and the connecting shaft 49 coincides with the holes of the first assembly 41 and the second assembly 42, and is clearance-fitted, and is assembled by the pin 45 (including the nut 46); the first assembly 41 and the second assembly 42 have a swing amplitude of 6 to 9 degrees relative to the connecting shaft; the first side wing 43 is connected to the electromechanical door head 1 with screws through the first side wing hole 47, and the second side wing 44 is connected to the door row 21 close to the electromechanical door head with screws through the second side wing hole 48; the electromechanical door head 1 drives the door row 21 to expand or contract, and the electromechanical door head 1 maintains its door body in a straight running state through the correcting device 4.

[0027] In this embodiment, two correcting devices 4 are spaced apart, significantly increasing the overall rigidity of the door and ensuring the stability of the sliding door. The electromechanical door head 1 drives the door body 2 and the running wheels 3 to expand or contract, while the correcting devices 4 maintain the door body 2 in a straight line. If the door body 1 deviates at a certain angle while moving, the correcting devices 4, with their rotational angle of 6 to 9 degrees relative to the door body 2, can return the door body 2 to its original position, thus correcting the deviation.

[0028] The structural design of the first side wing 43 and the second side wing 44 of the deviation-correcting device 4 of this embodiment is simple in structure, novel in shape, and easy to produce and process.

[0029] The door rows of this embodiment are connected to each other by rollers and chains. The door rows are parallel to each other and are no longer on the same plane, which can further reduce the installation process and save costs.

[0030] [Example 2]

[0031] like Figure 2The diagram shows a partial schematic diagram of the structure of a trackless electric sliding door with a corrective device according to Example 2 (one door row). This embodiment includes two corrective devices 4, spaced apart one above the other. A through-hole is defined in the center of the connecting shaft 49, through which the pin 45 passes to assemble the first assembly 41 and the second assembly 42. This embodiment, with only one door row, maintains a simple structure.

[0032] [Example 3]

[0033] Figure 3 、 Figure 4 It is a structural schematic diagram and an exploded diagram of the correction device for the sliding door of this embodiment.

[0034] The first assembly part 41 and the second assembly part 42 of the correction device of this embodiment are respectively provided with holes with the same cross-section as the connecting shaft 49, and the holes are through-holes and fit with the connecting shaft 49 with clearance. This design structure can further simplify the on-site installation process and improve assembly efficiency.

[0035] The pin 45 in this embodiment comprises a screw and a nut 46. The connecting shaft 49 has a central through-hole, through which the screw of the pin 45 passes, and is then assembled by assembling the first and second assemblies 41 and 42. A first washer 411 is placed at one end of the pin 45, and a third washer 412 is placed at the other end, and then assembled with a nut 46. A second washer 410 is also placed between the first and second assemblies 41 and 42 to effectively prevent friction between them. The first and second assemblies 41 and 42 have a swing range of 6 to 9 degrees relative to the connecting shaft 49. The connecting shaft 49 in this embodiment has a runway-shaped cross-section, meaning its left and right sides are straight and its top and bottom sides are arc-shaped. This unique design ensures a clearance fit between the connecting shaft and the first and second assemblies 41 and 42, and the holes, which also have a runway-shaped cross-section, align with each other. This significantly extends the service life of the correction device and significantly enhances its correction effectiveness. The connecting shaft with a runway circle cross section and the assembly hole with a runway circle cross section cooperate with each other, which significantly extends the service life of the correction device. This is the biggest improvement over the door row tractor with a rectangular connecting shaft cross section mentioned in the background technology. The door row tractor with a rectangular connecting shaft cross section mentioned in the background technology has a right-angled side, which causes large friction loss during use, and the angle required for its clearance fit is small. After long-term use, the correction effect is reduced due to wear. In the correction device of this embodiment, the connecting shaft with a runway circle cross section and the assembly hole with a runway circle cross section are in arc-shaped contact, resulting in a large friction surface, a long service life, and a greater tolerance for clearance fit requirements.
