Moreover, the existing electric gate does not have an over-travel protection device. In the case of the failure of the gate in-place sensor, the gate cannot stop when it reaches the position, which easily causes the motor to burn out. Content of the Utility Model

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a manual and electric integrated gate with over-travel protection, including a reduction motor, a gate housing and a gate. The innovation lies in that: the reduction motor is fixed on the side of the gate housing, an extension shaft is arranged in the reduction motor, a handle is arranged on the extension shaft, a screw rod is horizontally arranged inside the gate housing, the left and right ends of the screw rod are smooth rods, a screw pair is threadedly connected to the screw rod, the screw pair is fixedly connected to the gate, one end of the screw rod is in transmission connection with the horizontal output shaft of the reduction motor, when the screw pair moves to the smooth rod, it separates from the screw rod and the screw rod idles, door-opening protectors and door-closing protectors are respectively arranged at the left and right ends of the screw rod, door-opening sensors and door-closing sensors are respectively arranged at the top of the gate housing, the door-opening sensor corresponds to the door-opening protector, and the door-closing sensor corresponds to the door-closing protector.

[0005] Furthermore, rollers are arranged in sequence at the upper and lower ends of the gate housing, and the rollers limit and guide the gate.

[0006] Furthermore, the door-opening protector and the door-closing protector have the same structure and are composed of a compression spring or a compressible rubber body.

[0007] After adopting the above structure, the beneficial effects of the utility model are as follows:

[0008] Through the manual and electric integrated structure, the utility model can manually start the gate through the handle in the case of motor failure, improving the applicability of the gate; through the over-travel protection device, in the case of the failure of the gate in-place sensor, the screw rod and the screw pair are separated, enabling the reduction motor to idle, thereby protecting the reduction motor and avoiding the motor from burning out.

[0012] The present utility model will be further described below with reference to the accompanying drawings.

[0013] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be understood that the specific implementation manners described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0014] Refer to Figure 1 , a manual and electric integrated gate with over-travel protection, including a reducing motor 1, a gate housing 2 and a gate 3. The reducing motor 1 is fixed on the side of the gate housing 2. An extension shaft is provided in the reducing motor 1, and a handle 4 is provided on the extension shaft. A screw rod 5 is horizontally arranged inside the gate housing 2. The left and right ends of the screw rod 5 are smooth rods. A screw pair 6 is threadedly connected to the screw rod 5. The screw pair 6 is fixedly connected to the gate 3. One end of the screw rod 5 is in transmission connection with the horizontal output shaft of the reducing motor. When the screw pair 6 moves to the smooth rod, it is separated from the screw rod 5, and the screw rod idles. Door-opening protectors 7 and door-closing protectors 8 are respectively arranged at the left and right ends of the screw rod 5. Door-opening sensors 9 and door-closing sensors 10 are respectively arranged at the top of the gate housing 2. The door-opening sensor 9 corresponds to the door-opening protector 7, and the door-closing sensor 10 corresponds to the door-closing protector 8. Specifically, when the reducing motor 1 fails, the gate can be manually rotated through the handle 4, and the gate plate 3 can be driven by the screw rod 5 to perform the door opening and closing operations;

[0015] During normal gate operation, the reducing motor 1 drives the screw rod 5 to rotate, and the screw pair 6 moves synchronously with the gate plate 3. When the gate plate 3 touches the door-opening sensor 9, the door-opening sensor 9 acts, and the reducing motor 1 stops reversing, and the door-opening operation ends. When the gate plate 3 touches the door-closing sensor 10, the door-closing sensor 10 acts, and the reducing motor 1 stops rotating forward.

[0016] When the gate is in the process of opening or closing the door, and the door-opening sensor 9 or the door-closing sensor 10 fails, the screw rod 5 will drive the screw pair 6 to move a certain distance. At this time, the door-opening protector 7 or the door-closing protector 8 will be compressed. After the door-opening protector 7 or the door-closing protector 8 is compressed, at this time, the screw pair 6 is located at the smooth rod, and the screw rod 5 is separated from the screw pair 6. At this time, the reducing motor 1 can only drive the screw rod 5 to idle, avoiding the burnout of the reducing motor 1 due to overload.

[0017] The opening protector 7 and the closing protector 8 are combined into an over-travel protection device, which is also to prevent the screw pair 6 after detachment from completely disengaging from the screw.

[0018] In this embodiment, rollers 11 are arranged at the upper and lower ends of the gate housing 2 respectively. The rollers 11 limit and guide the gate 3. The rollers 11 reduce the friction with the gate 3, which is beneficial to the movement of the gate 3.

[0019] In this embodiment, the opening protector 7 and the closing protector 8 have the same structure and are composed of a compression spring or a compressible rubber body. When the opening protector 7 and the closing protector 8 are under pressure, they react on the screw pair 6. After the screw pair 6 is under a certain degree of pressure, it will disengage from the screw 5, so that the reduction motor can run idly, avoiding the motor being burned out due to overload.

[0020] The above is only used to illustrate the technical solution of the present invention and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention shall be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
