It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0027] The embodiments of the present utility model disclose a transmission wheel structure and a linkage door having the transmission structure. To better understand the inventive concept of the technical solution of the present application, the meaning of the linkage door can be understood first. The linkage door refers to the synchronous opening and closing of multiple doors achieved through mechanical or electronic means, and the traction linkage of a conveyor belt and a transmission wheel can be specifically adopted to complete the linkage movement of multiple door leaves. However, it is found in the long-term use process that the conveyor belt will have a problem that the tightness does not meet the use conditions, that is, the conveyor belt slack problem. To solve the mentioned problem, the technical solution of the present application improves the transmission structure in the linkage door.

[0028] The following Figures 1-6 describes a transmission wheel structure in the present application.

[0029] In some embodiments, the transmission wheel structure may specifically include a base 1 and an adjustment seat 2 slidably disposed on the base 1. The adjustment seat 2 is provided with a rotatable belt pulley 21; the base 1 is provided with a rotatable driving rod 3, and the driving rod 3 is threadedly connected to the adjustment seat 2. The driving rod 3 is configured to rotate itself to adjust the relative positions of the adjustment seat 2 and the belt pulley 21 on the base 1. In practical applications, the base 1 needs to be fixed on the linkage door body, and the belt pulley 21 needs to be used to tension the conveyor belt. When it is necessary to adjust the tightness of the conveyor belt, the driving rod 3 can be rotated, and by using the principle of screw transmission, the relative positions of the adjustment seat 2 and the belt pulley 21 on the base 1 can be adjusted, and the conveyor belt can be specifically tightened to ensure that the tightness of the conveyor belt meets the use requirements and prevent the conveyor belt from slackening.

[0030] In summary, the present application can specifically adjust the relative positions of the adjusting seat 2 and the pulley 21 on the base 1 through the threaded engagement structure of the driving rod 3, thereby tightening the conveyor belt, preventing the conveyor belt from loosening, and ensuring that the tightness of the conveyor belt meets the usage requirements.

[0031] In some embodiments, the adjusting seat 2 includes a sliding portion 22 slidably disposed on the base 1. The sliding portion 22 has a chute 23 penetrating along the sliding direction, and the base 1 includes a slide rail 14 slidably disposed in the chute 23. During actual use, since the adjusting seat 2 needs to slide on the base 1, in order to ensure the smoothness and stability of the sliding structure, the chute 23 is provided on the sliding portion 22 of the adjusting seat 2, and the slide rail 14 is provided on the base 1, so that the sliding of the adjusting seat 2 is more stable.

[0032] Specifically, the chute 23 includes a vertically connected vertical groove section 231 and a horizontally connected horizontal groove section 232. The slide rail 14 includes a vertical track 141 slidably disposed in the vertical groove section 231 and a horizontal track 142 slidably disposed in the horizontal groove section 232. For example, the shapes of the chute 23 and the slide rail 14 can be specifically L-shaped or T-shaped. With such a setting, it can well ensure that the force on the adjusting seat 2 is more balanced during sliding, and prevent the adjusting seat 2 from warping and shaking.

[0033] Specifically, there are two chutes 23 and two slide rails 14. One chute 23 is slidably disposed with one slide rail 14, and the driving rod 3 is disposed between the two chutes 23. During actual use, the adjusting seat 2 is specifically moved by rotating the driving rod 3. Therefore, in order to further avoid the warping and shaking of the adjusting seat 2, two chutes 23 can be specifically provided in the adjusting seat 2, two slide rails 14 are adaptively provided at corresponding positions on the base 1, and the driving rod 3 is disposed between the two chutes 23, thereby forming a sliding structure that can be stressed on both sides, which can better ensure that the force on the adjusting seat 2 is more balanced during sliding, and prevent the adjusting seat 2 from warping and shaking.

[0034] In some embodiments, a bendable anti-detachment member 11 is provided on one side wall of the slide rail 14 of the base 1. The anti-detachment member 11 is configured to be bent downward and located on the moving path of the sliding portion 22 of the adjusting seat 2. Since the relative position of the adjusting seat 2 on the base 1 needs to be adjusted in actual application, it is found in practice that there is a problem that the adjusting seat 2 falls off the base 1 during movement on the base 1. Therefore, in order to prevent the adjusting seat 2 from falling off the base 1, a bendable anti-detachment member 11 is provided on the base 1. After the adjusting seat 2 is assembled on the base 1, the anti-detachment member 11 can be bent so that the anti-detachment member 11 blocks the moving path of the adjusting seat 2, thereby forming a blocking effect on the adjusting seat 2 and effectively preventing the adjusting seat 2 from falling off the base 1.

[0035] In a specific embodiment, at least two anti - detachment members 11 are provided, and at least two anti - detachment members 11 are spaced apart on the base 1. With such an arrangement, the adjustment seat 2 can be blocked and prevented from detachment more stably.

[0036] In some embodiments, external threads are provided on the circumferential outer wall of the driving rod 3, and the adjustment seat 2 has internal threads matching the external threads of the driving rod 3. With such an arrangement, external threads are provided on the circumferential outer wall of the driving rod 3, that is, the driving rod 3 can be specifically a threaded rod, which can effectively increase the movable distance of the adjustment seat 2 and the pulley 21 on the base 1, and can adjust the tightness of the conveyor belt in a larger range.

[0037] In some embodiments, an annular groove 31 is recessed in the circumferential outer wall of the driving rod 3, and a clamping block 32 is sleeved at the annular groove 31, and the clamping block 32 is inserted into a clamping groove 12 on the base 1. It is found in practical applications that since the driving rod 3 itself rotates, according to the principle of screw drive, the driving rod 3 needs to be limited and cannot move in order to adjust the relative positions of the adjustment seat 2 and the pulley 21 on the base 1. Since the driving rod 3 may rotate clockwise or counterclockwise in practice, in order to better limit the driving rod 3 and prevent the driving rod 3 from disengaging from the base 1, the cooperation of the annular groove 31 of the driving rod 3, the clamping block 32 and the clamping groove 12 of the base 1 can be specifically adopted to limit the driving rod 3 on the base 1 through the clamping block 32 to prevent the driving rod 3 from disengaging from the base 1, and the structure will be more stable; at the same time, with such an arrangement, the structure will also be more compact, which is beneficial to reducing the overall occupied space.

[0038] Specifically, the facing surfaces between the annular groove 31 of the driving rod 3 and the clamping block 32 can be set smoothly. Since the driving rod 3 itself needs to rotate, in order to make the rotation of the driving rod 3 smoother, the facing surfaces between the annular groove 31 of the driving rod 3 and the clamping block 32 can be specifically set to be smoother to reduce the friction coefficient between the two.

[0039] In a specific embodiment, an assembly groove 13 for limiting the driving rod 3 is recessed in the base 1, and the opposite side walls of the assembly groove 13 extend outward to form the clamping groove 12, and the bottom of the assembly groove 13 and the bottom of the clamping groove 12 are flush. With such an arrangement, the driving rod 3 can be assembled into the assembly groove 13, which can not only make the overall structure more compact, further reduce the overall occupied space, but also use the base 1 to protect the driving rod 3 to prevent the driving rod 3 from contacting other workpieces and affecting the smoothness of rotation.

[0040] In some embodiments, the adjustment seat 2 is inserted into the base 1 and is configured to be inserted into the base 1 from the side of the base 1. With such an arrangement, not only the structure is simple, which is convenient for manufacturing and production and reduces the manufacturing difficulty, but also the adjustment seat 2 can be assembled on the base 1 more conveniently and quickly.

[0041] The technical means disclosed by the solution of the present utility model are not limited to the technical means disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications are also regarded as the protection scope of the present utility model.
