[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.

[0029] Embodiment 1 of this utility model:

[0030] like Figures 1-6As shown, the automatic pigeon gate opening and closing device includes a drive unit and an elastic pulling unit. The drive unit includes a motor and a roller 2, which is connected to the motor shaft 91 of the motor for transmission. The motor is located in a rectangular box 1, which is used to fix the pigeon cage. The box 1 has a cable channel for the power cord (not shown) to pass through. The force required to drive the pigeon gate is not large, and a miniature geared motor can be used. The box is made of stainless steel, the motor is built-in, and it is waterproof and has sufficient thermal conductivity to meet the motor's heat dissipation requirements.

[0031] like Figure 3 As shown, one side of the motor shaft 91 has an anti-rotation plane for inserting and anti-rotation into the center hole 24 of the roller 2. The motor shaft 91 has a threaded hole 911, through which a limit pin is connected. The limit pin passes through the center hole 24 of the roller 2 and is connected in the threaded hole 911. During installation, the roller 2 is first installed, and then the limit pin is inserted. The limit pin serves to limit the axial movement of the roller 2 without affecting its rotation.

[0032] like Figure 4 As shown, the roller 2 is made of stainless steel and includes a first winding reel 21 and a second winding reel 22. Both the first winding reel 21 and the second winding reel 22 have annular winding cavities. The first winding reel 21 is used for winding and unwinding the first rope segment 31, and the second winding reel 22 is used for winding and unwinding the second rope segment 32. The two winding reels are spaced apart and do not affect each other. The first rope segment 31 and the second rope segment 32 can be understood as two segments of the wire rope 4. Since the wire rope is movable in this example, the so-called first rope segment 31 and second rope segment 32 are not completely fixed. Taking the reversing point of the wire rope 4 as the boundary, one segment is the first rope segment 31, and the other segment is the second rope segment 32.

[0033] The bottom of the annular rope-winding cavity is provided with an insertion hole 23 for inserting one end of the first rope segment 31 and the second rope segment 32, which is a free end. During initial installation, one end of the first rope segment 31 and the second rope segment 32 is inserted into the corresponding insertion hole 23, and then winding begins, with the winding directions being opposite. In other embodiments, the free ends of the wire rope can also be welded and fixed. The first rope segment 31 and the second rope segment 32 move in opposite directions, and the first rope segment 31 and the second rope segment 32 are respectively provided with a first fixing part 41 and a second fixing part 42 for connecting with the corresponding gate body of the pigeon gate.

[0034] In this embodiment, as Figure 1As shown, the pigeon gate is a two-door sliding door, comprising a first door body 51 and a second door body 52. ​​A first fixing part 41 is connected to the first door body 51, and a second fixing part 42 is connected to the second door body 52. ​​When the wire rope moves, both the first door body 51 and the second door body 52 can be pulled simultaneously. Since the first rope segment 31 and the second rope segment 32 move in opposite directions, when the roller 2 rotates, the first door body 51 and the second door body 52 also move in opposite directions, allowing them to move towards each other to close or away to open. The bottoms of the first door body 51 and the second door body 52 slide in the slide rail 8, which is existing technology for pigeon cages and pigeon gates. In this embodiment, the first fixing part 41 and the second fixing part 42 are applied to the upper part of the respective door body, applying a pushing or pulling force.

[0035] The first fixing part 41 and the second fixing part 42 use rope clips, such as Figure 6 As shown, the rope clamp includes a rope buckle and a connecting plate 414. The rope buckle 411 has a linear groove and clamps and fixes the corresponding rope segment. The connecting plate 414 is an L-shaped plate, which better fits against one side of the door. The connecting plate 414 has screw holes for connection with corresponding door screws, thus achieving synchronous movement between the fixing part and the door. The rope buckle includes a buckle plate 411, which is connected to one side plate of the connecting plate 414 by a bolt 413. A clamping nut 412 is provided between the buckle plate 411 and the side plate to clamp the corresponding rope segment. The clamping nut 412 is threaded onto the bolt 413, and the end of the bolt also has a locking nut to ensure a tight fit between the connecting plate 414 and the buckle plate 411. The other side plate of the connecting plate 414 has the aforementioned screw holes. The buckle plate 411 and the clamping nut 412 cooperate to fix the corresponding rope segment of the wire rope 4 to the buckle plate 411, and then the connecting plate 414 is fixed to the door by screws. The rope clamp can be an existing one, the purpose of which is to fix a point of the wire rope to the door body to achieve synchronous movement of the two. In other embodiments, the location of the fixing part of the rope segment can be directly welded to the door body, or the rope segment can be wrapped around a screw and then the screw can be used to directly press the rope segment to the door body.

[0036] like Figure 1 and 5 As shown, the elastic tensioning part includes a spring 7 and a pulley buckle 6. The spring 7 is a tension spring. One end of the spring 7 is fixed to the pigeon cage, and the other end is connected to the pulley buckle 6. The junction of the first rope segment 31 and the second rope segment 32 passes around the pulley 62 of the pulley buckle 6. It can be understood that the first rope segment 31 and the second rope segment 32 are two parts of the same steel wire rope, which are reversed at the pulley 62.

[0037] The structure of the pulley buckle 6 is existing technology, including a housing 61 and a pulley 62. The pulley 62 is rotatably assembled in the housing 61. A hanging ring 63 is provided on one side of the housing 61 for one end of the spring 7 to be hooked.

[0038] The working principle of this automatic pigeon gate opening and closing device:

[0039] like Figure 1 As shown, the motor is started remotely via a remote control or mobile phone. When the motor rotates forward, the roller 2 rotates synchronously forward. The first rope segment 31 winds onto the roller 2 and moves the first door body 51 toward the motor via the first fixing part 41. Conversely, the second rope segment 32 unwinds and moves the second door body 52 toward the spring 7 via the second fixing part 42, thus achieving the opening effect. When the motor rotates in reverse, the roller 2 rotates synchronously in reverse. The first rope segment 31 unwinds and moves the first door body 51 toward the spring 7 via the first fixing part 41. Conversely, the second rope segment 32 winds onto the roller 2 and moves the second door body 52 toward the motor via the second fixing part 42, thus achieving the closing effect.

[0040] The spring 7 is designed to adjust the length of the wire rope. Because the actual effective length of the wire rope will change slightly as the first rope segment 31 is wound or unwound, the spring 7 can be used to adjust it accordingly.

[0041] Embodiment 2 of this utility model:

[0042] The automatic pigeon gate opening and closing device in this embodiment has a basically the same structure as that in Embodiment 1, but the application scenarios are slightly different. In this embodiment, both the first fixing part 41 and the second fixing part 42 are fixed to the same gate body. Figure 2 As shown, both the first fixing part 41 and the second fixing part 42 are fixed to the movable door body 53, respectively, by screws on both sides of the movable door body 53 in the width direction. The first fixing part 41 and the second fixing part 42 are both located on the same rope segment, namely the second rope segment 32. In other embodiments, they may both be located on the first rope segment 31. The individual structures of the first fixing part 41 and the second fixing part 42 are the same as those in Embodiment 1, only the installation position is different.

[0043] like Figure 2 As shown, during use, the motor is started remotely via remote control or mobile phone. When the motor rotates forward, the roller 2 rotates forward synchronously. The first rope segment 31 winds onto the roller 2, and the second rope segment 32 unwinds. The roller 2 moves towards the spring 7 via the first fixing part 41 and the second fixing part 42, thus opening the door. When the motor rotates in reverse, the roller 2 rotates in reverse synchronously. The first rope segment 31 unwinds, and the second rope segment 32 winds onto the roller 2. The roller 2 moves towards the motor via the first fixing part 41 and the second fixing part 42, thus closing the door. The forward and reverse rotation of the motor allows the movable door 53 to move linearly to the right or left, opening or closing the door.

[0044] In other embodiments, an improvement can be made based on embodiment 2 by designing a fixing part that is connected to the movable door body 53.
