Technical Field
[0001] The utility model relates to the technical field of retractable door equipment, and particularly relates to a turning retractable door. Background Art
[0002] A retractable door is a door that can move the door body freely to control the size of the door opening to intercept and release pedestrians or vehicles. The retractable door mainly consists of a door body, a power device, a slideway, and a control system. The power device is driven by an electric motor and decelerated by a reducer, and the power is transmitted to the door body to control the retractable door to slide on the track to realize opening and closing. The control system has a control board and a button switch, and a wireless remote control device can be used to transmit signals to the control board to control the switch.
[0003] The existing retractable doors are relatively large and still occupy a lot of space even after being folded. They are only suitable for installation in large factories or communities. For some small courtyards or other smaller spaces, there is no space for installation, and the shape does not match the environment and is not beautiful. The existing turning retractable doors lack a suitable limiting device and the traditional wheel-rail cooperation is prone to derailment. Therefore, it is urgent to design a turning retractable door to solve the above problems. Summary of the Utility Model

[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A turning retractable door includes a track. A number of unit moving sections are installed above the track. There is a limiting device fixedly installed on the wall at the top of the unit moving section. On one side of the bottom of the last unit moving section, a power device is fixedly installed. The power device includes a mounting plate. On one side of the upper surface of the mounting plate, a motor is fixedly installed. In the middle of the upper surface of the mounting plate, a reducer is fixedly installed. The reducer is connected to the motor through a shaft transmission. On the other side of the upper surface of the mounting plate, a pair of transmission shaft mounting brackets are fixedly connected. On one side of the reducer, a driving gear is connected through a shaft transmission. On both sides of the driving gear, a pair of driven gears are meshed.

At the rear end of one side of the door body, a lower hinge is fixedly connected. At the front end of the bottom of the door body, a V-shaped wheel is fixedly installed. At one side of the bottom of the door body, a rack mounting bracket is fixedly connected. Below one side of the rack mounting bracket, a rack is fixedly connected. The rack is meshed and linked with a transmission gear.
[0008] Preferably, the track includes an arc section and two straight sections. The radius of the arc section is 0.5 to 1.5 times the length of the unit moving section.
[0009] Preferably, the limiting device includes a limiting frame. At the bottom of one side of the limiting frame, a limiting wheel is fixedly connected. The number of the limiting devices is several.

[0028] In an embodiment provided by the present utility model, the unit moving section 2 includes a door body 21. A top hinge 22 is fixedly connected to the front end of one side of the door body 21, and a bottom hinge 23 is fixedly connected to the rear end of one side of the door body 21. A V-shaped wheel 24 is fixedly installed at the front end of the bottom of the door body 21, and the inner side of the V-shaped wheel at the arc of the track 1 needs to be cut off to ensure that the unit moving section moves linearly on the arc section of the track 1.

The toothed plate 26 is meshed with a transmission gear 37.
[0029] In another embodiment provided by the present utility model, the track 1 includes an arc section and two straight sections. The radius of the arc section is 0.9 to 1.1 times the length of the unit moving section 2. The track 1 is a circular track, and correspondingly, the unit moving section 2 adopts a V-shaped wheel 24.
[0030] In still another embodiment provided by the present utility model, the number of the limiting devices 4 is preferably 2, which are located on the upper wall of the two adjacent unit moving sections 2 at the end. The limiting device 4 includes a limiting frame 41, and the limiting frame 41 is integrally formed by bending sheet metal.

The number of the limiting devices 4 is several, and the number of the limiting wheels 42 on one limiting frame 41 is preferably 2.
[0031] In an embodiment provided by the present utility model, a pair of top hinges 22 and a pair of bottom hinges 23 are used to connect the adjacent unit moving sections 2, and a rotational connection is formed through the top hinges 22 and the bottom hinges 23. Moreover, the structures and specifications of each unit moving section 2 are the same, and the middle part of the unit moving section 2 is a hollow structure.
[0032] In another embodiment provided by the present utility model, a limiting block 5 is fixedly installed on the ground outside the arc section of the track 1. The limiting block 5 is located at the intersection of the two straight lines of the track. The limiting block is formed by driving a section of steel bar into the ground first, and a section needs to be exposed on the ground, and then cement is poured on this exposed section of the steel bar to form a cube.
[0033] Working principle: When closing the retractable door, press the switch. The motor 32 rotates forward, transmits the power to the driving gear 34 through the reducer 33, causing the driving gear 34 to rotate. The rotation of the driving gear 34 drives the driven gear 35 to rotate. The rotation of the driven gear 35 drives the transmission gear 37 to rotate through the transmission shaft 36. The rotation of the transmission gear 37 causes the engaged tooth plate 26 to move translationally, thereby realizing the movement of the door body 21. The unit moving section moves along the track 1 under the restriction of the limiting device 3. After the unit moving section 2 at the top is about to reach the position, the power device drives the rear half of the unit moving section 2 to continue moving forward and stops moving under the action of the limiting block 5 on the arc section of the track 1, forming a right angle with the front half of the unit moving section. When opening the retractable door, just control the switch to make the motor 32 rotate in reverse to drive the retractable door to contract. The circuit inside the power device 3 is provided with an infrared signal receiving device to control the switch. When the remote control or the monitoring device at the door recognizes the stored vehicle license plate and face, it will emit a signal to control the opening and closing of the door.
[0034] Only some exemplary embodiments of the present invention are described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
