[0038] Embodiment:

[0039] Referring to Figure 1 and Figure 2The embodiment discloses a chain transmission window, which comprises a box body 10, shaft bodies 20, door plates 30 and control rods 41. The box body 10 is in the shape of a hollow cuboid, and the two ends of the box body 10 are through, and a channel 12 is formed in the box body 10, and the channel 12 can be used to place or take articles. During installation, the length direction of the box body 10 is arranged along the horizontal direction. A control part 11 in a hollow structure is arranged on the top of the box body 10.

[0040] A shaft body 20 is arranged at each end of the box body 10, and the shaft bodies 20 are arranged along the vertical direction and are rotationally connected with the box body 10. One end of the shaft body 20 is arranged at the bottom of the box body 10, and the other end of the shaft body 20 penetrates into the control part 11. The shaft bodies 20 at the two ends of the box body 10 are close to the two sides of the box body 10 respectively.

[0041] A door plate 30 is arranged on each shaft body 20. The end of the door plate 30 is fixedly connected with the shaft body 20, and the other end of the door plate 30 is provided with a control hole 31 in the top. The door plate 30 can completely cover the end of the box body 10.

[0042] Two control rods 41 are arranged in the control part 11. When the two door plates 30 are in the closed state at the ends of the box body 10, the two control rods 41 are located above the two control holes 31 respectively. In addition, the two control rods 41 are dynamically connected with the two shaft bodies 20 respectively, and the control rod 41 at one end of the box body 10 is dynamically connected with the shaft body 20 at the other end of the box body 10.

[0043] In the embodiment, the shaft bodies 20, the door plates 30 and the control rods 41 at the two ends of the box body 10 are in a central symmetric structure. The box body 10 is arranged, and the channel 12 is formed in the box body 10. The control part 11 is arranged on the top of the box body 10. The control rods 41 are arranged in the control part 11. The shaft bodies 20 arranged on the door plates 30 are used to link the control rods 41. When one of the door plates 30 is opened, the control rod 41 on the other door plate 30 automatically falls into the control hole 31 on the other door plate 30, so that the mechanical door locking is realized. Through the technical scheme, the chain control transmission window can be realized without arranging the power supply circuit.

[0044] In one specific embodiment,

[0045] The chain transmission window further comprises a connecting rod 42, a pressing rod 43, a pressure bearing plate 44 and a spring 45. The connecting rod 42 is arranged in the control part 11 along the horizontal direction, and the connecting rod 42 is movably arranged in the control part 11 and can move along the length direction of the connecting rod 42. The two ends of the connecting rod 42 are close to the two ends of the box body 10 respectively, and the length direction of the connecting rod 42 is consistent with the length direction of the box body 10.

[0046] The one end of the connecting rod 42 is connected with the shaft body 20 through the gear and the gear rack 46, so that the shaft body 20 drives the connecting rod 42 to move linearly when the door plate 30 is opened or closed.

[0047] The middle part of the pressing rod 43 is rotatably arranged in the control part 11 through a support 47 fixedly arranged in the control part 11, and the pressing rod 43 is rotatably connected with the support 47.

[0048] The other end of the connecting rod 42 is slidably connected with one end of the pressing rod 43, and the other end of the pressing rod 43 is connected with the control rod 41. Specifically, a pressure bearing plate 44 is arranged on the one end of the control rod 41 located in the control part 11, the length direction of the pressure bearing plate 44 is perpendicular to the control rod 41, and the pressure bearing plate 44 and the control rod 41 form a T-shaped structure. The other end of the connecting rod 42 is slidably arranged on the top surface of the pressure bearing plate 44.

[0049] In the embodiment, when the door plate 30 is opened or closed, the shaft body 20 rotates, the connecting rod 42 is driven to move along the length direction through the gear and the gear rack 46, and then the end of the connecting rod 42 pulls the pressing rod 43 to rotate on the support 47, so that the end of the pressing rod 43 presses or pulls up the control rod 41.

[0050] In the process, when one of the door plates 30 is opened by a small angle, the control rod 41 of the other door plate 30 moves into the control hole 31 by a small distance, so as to lock the other door plate 30, and only when one of the door plates 30 is completely closed, the other door plate 30 can be opened, so that the structure disclosed in the technical solution can realize the purpose of opening only one door plate 30 at a time.

[0051] Preferably, a spring 45 is arranged between the pressure bearing plate 44 and the bottom surface of the control part 11. When the end of the pressing rod 43 is driven to move upward by the connecting rod 42, the control rod 41 can be driven to move upward by the spring 45 to move away from the control hole 31.

[0052] In another specific embodiment:

[0053] The two ends of the pressing rod 43 form an included angle greater than 90° and less than 135°, so that the positions of the control rod 41 and the connecting rod 42 can be reasonably arranged.

[0054] In another specific embodiment:

[0055] The control part 11 is provided with two intermediate shafts 48, and each of the intermediate shafts 48 is provided with a pinion and a belt wheel, and the two belt wheels are connected through a belt. One end of the shaft body 20 is provided with a large gear, the large gear is engaged with one of the pinions, the other pinion is engaged with a rack 46, and the rack 46 is arranged at the end of the connecting rod 42. The transmission ratio of the large gear to the pinion is greater than 3:1. The diameter of the pinion engaged with the rack 46 is greater than the diameter of the other pinion.

[0056] In the embodiment, by arranging the intermediate shaft 48, the large gear and the pinions, and controlling the transmission ratio of the large gear to the pinions and the diameter difference between the two pinions, the rotation angle of the pinion is greater than 360° when the rotation angle of the shaft body 20 is less than 180°, and the displacement length of the connecting rod 42 when the door plate 30 is opened or closed is improved.

[0057] The above-described embodiments only express the specific implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as the limitation of the patent scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, and these all belong to the protection scope of the present application.
