Description

Technical Field

[0001] This utility model belongs to the field of suspended door technology, specifically relating to a friction drive device for a suspended door. Background Technology

[0002] A suspended gate is a type of gate that moves in mid-air without wheels touching the ground, without running tracks, and without the need for pre-embedded guide rails. It is driven by a transmission mechanism when opening and closing.

[0003] Currently, most suspended gates on the market use rack and pinion drives, which have several significant drawbacks. First, the drive noise is excessive, which can be problematic in noise-sensitive environments such as residential areas, schools, and hospitals. Second, with prolonged use, the wear and tear is too rapid, affecting not only transmission efficiency and stability but also increasing maintenance costs and replacement frequency. Furthermore, the exposed rack and pinion mechanism detracts from the overall aesthetics of the suspended gate, failing to meet high expectations for its appearance.

[0004] Therefore, a new type of suspended door drive device is needed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a floating door drive device that is driven by friction and is adjustable.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A friction drive device for a suspended door includes a central support device and a front drive device, wherein an adjustment device is provided on the front drive device.

[0008] The central support device includes a first support plate, on which several pairs of load-bearing wheels are symmetrically arranged and distributed at the upper and lower ends of the first support plate, and a mounting frame is provided at the bottom of the first support plate.

[0009] The front drive device includes a second support plate and four pairs of load-bearing wheels symmetrically arranged on both sides thereon. A mounting bracket is provided at the bottom of the second support plate.

[0010] An adjusting seat is fixedly connected to one end of the second support plate. A driving component is rotatably connected to the adjusting seat. Two pairs of driving wheels are connected to both sides of the driving component, and the driving wheels on both sides are located at the upper and lower ends of the driving component, respectively. The adjusting device is disposed between the adjusting seat and the driving component.

[0011] Furthermore, the adjusting device includes an adjusting screw threaded to the end of the adjusting seat, the top of the adjusting screw abutting against the driving member, and an adjusting handwheel provided at the bottom of the adjusting screw.

[0012] Furthermore, several pairs of lateral travel wheels are provided on both sides of the first and second support plates.

[0013] Furthermore, the driving component is a motor and a reducer that is driven and connected to the motor, and the driving wheel is driven and connected to the reducer.

[0014] Furthermore, the drive wheel is made of soft polyurethane material.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. Excellent aesthetics: The friction structure and motor are hidden inside the door body, avoiding the problem of exposed rack and motor in traditional rack and pinion transmission, making the cantilever door more aesthetically pleasing overall.

[0017] 2. Low transmission noise: It adopts a friction drive method, and there is basically no transmission noise during the transmission process, which can create a quiet atmosphere for use, and is especially suitable for noise-sensitive places.

[0018] 3. Long service life: The soft friction wheel, combined with an adjustable tension structure, results in slow wear. When the friction drive wheel experiences insufficient contact with the suspended gate drive guide groove due to wear or other factors, the tension adjustment mechanism can be used to change the pitch angle of the rotating seat to press the friction drive wheel tightly against the suspended gate drive guide groove, ensuring stable power transmission, extending the service life of the device, and making it durable.

[0019] 4. Easy to install and maintain: The rotating seat and tension adjustment mechanism make it very convenient to engage and disengage the friction drive wheel and the suspended door body. When installation or maintenance is required, the friction drive wheel can be released for easy operation. At the same time, under certain conditions, the friction wheel can be released to allow the door body to be manually pushed and pulled, which improves the flexibility of use.

[0028] Please see Figure 1-2 The friction drive device for a suspended door shown in a preferred embodiment of this application includes a central support device and a front drive device, wherein:

[0029] The central support device includes a first support plate 1. Four pairs of load-bearing wheels 2 are symmetrically arranged on both sides of the first support plate 1 and distributed at the upper and lower ends of the first support plate 1. A mounting frame 4 is provided at the bottom of the first support plate 1. Two sets of waist-shaped holes are opened at the bottom of the mounting frame 4 and are installed inside the bottom beam of the suspended door through the waist-shaped holes.

[0030] The front drive unit includes a second support plate 5 and four pairs of load-bearing wheels 2 symmetrically arranged on both sides thereon. The bottom of the second support plate 5 is also provided with a mounting bracket 4 for connecting the bottom beam.

[0031] Furthermore, an adjusting seat 6 is fixedly connected to one end of the second support plate 5, and a driving component is rotatably connected to the adjusting seat 6. Two pairs of driving wheels 7 are connected to both sides of the driving component. The driving wheels 7 on both sides are located at the upper and lower ends of the driving component, respectively. An adjusting screw 10 is threadedly connected to the end of the adjusting seat 6. The top of the adjusting screw 10 abuts against the driving component, and an adjusting handwheel 11 is provided at the bottom of the adjusting screw 10.

[0032] Preferably, two pairs of lateral walking wheels 3 are also provided on both sides of the first support plate 1 and the second support plate 5 to limit the lateral movement of the drive guide groove of the suspended door.

[0033] Preferably, in this embodiment, the driving components are a reducer 8 and a motor 9 that is connected to it in a transmission, and the driving wheel 7 is connected to the reducer 8 in a transmission.

[0034] Preferably, the drive wheel 7 is made of soft polyurethane, which has the characteristics of oil resistance, wear resistance, low temperature resistance, aging resistance, high hardness, high elasticity, and good sound insulation and vibration damping performance.

[0035] Working principle:

[0036] Several central support devices are installed inside the bottom beam of the suspended gate, and the front drive device is installed at the end of the bottom beam and distributed along the same axis. When in use, the drive wheels at the upper and lower ends of the drive unit abut against the upper and lower sides of the drive guide groove of the suspended gate. After the motor is started, the drive wheels drive the suspended gate to move through friction and are supported by the central support devices.

[0037] When the drive wheel is worn and makes insufficient contact with the suspended door, the adjustment screw is lowered by rotating the adjustment handwheel. At this time, the drive wheels at the upper and lower ends of the drive component are offset to the upper and lower ends respectively, so as to effectively contact and press the suspended door. In special cases, the drive wheel can also be adjusted to move away from the suspended door, so that the suspended door can be pushed and pulled manually.

[0038] In addition, this structure can easily achieve the disengagement and retraction of the drive wheel and the suspended door body, which facilitates the installation and maintenance of the suspended door and represents a significant improvement over existing technologies.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
