[0027] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances. Example

[0028] like Figure 1-3 As shown, the utility model proposes a toothed chain plate with anti-slip components, including an outer plate 1 and a guide plate 2, the guide plate 2 includes a first guide plate 21, a second guide plate 22, and a third guide plate 23, the outer plate 1 is provided with two groups, and the guide plate 2 is movably connected to the middle of the two groups of outer plates 1 through a connecting pin 11.

[0029] Among them, two groups of first connecting holes 101 are provided on the outer plate 1, and several groups are provided on the guide plate 2. The number of guide plates 2 depends on the width of the sprocket in the actual working environment. Second connecting holes 201 are provided on the first guide plate 21, the second guide plate 22, and the third guide plate 23. The connecting pins 11 pass through the first connecting hole 101 and the second connecting hole 201 respectively.

[0030] In addition, the first connecting hole 101 on the right side of the outer panel 1 is concentrically arranged with the second connecting hole 201 on the left side of the first guide plate 21 and the second connecting hole 201 on the right side of the third guide plate 23, and the first connecting hole 101 on the left side of the outer panel 1 is concentrically arranged with the second connecting hole 201 on the right side of the second guide plate 22 and the second connecting hole 201 on the left side of the third guide plate 23, and the guide plate 2 is installed between the two groups of outer panels 1 through the connecting pin 11.

[0031] Finally, a positioning bar 111 is fixedly installed on the connecting pin 11, and a mounting bolt 8 is threadedly connected to one end of the connecting pin 11. A threaded hole 112 that is compatible with the mounting bolt 8 is provided at one end of the connecting pin 11. The mounting bolt 8 is threadedly connected to the threaded hole 112 of the connecting pin 11, which is not easy to loosen, thereby improving the stability of the toothed chain plate during operation. The first connecting hole 101 and the second connecting hole 201 are both provided with grooves that are compatible with the positioning bar 111. The positioning bar 111 is used to improve the stability of the connection between the connecting pin 11 and the outer plate 1 and the guide plate 2.

[0032] In this embodiment, the limit assembly includes a rectangular plate 3, and several groups of limit rods 5 are fixedly installed on the bottom of the rectangular plate 3. The limit assembly also includes fixed rods 4 fixedly installed at both ends of the rectangular plate 3. The fixed rods 4 are respectively fixedly connected to the outer plate 1, and the limit rods 5 are respectively inserted between two adjacent groups of third guide plates 23. When the bottom of the guide plate 2 is engaged with the sprocket, the guide plate 2 rotates around the connecting pin 11, and the limit rod 5 limits the rotation of the connecting pin 11, reducing the friction between the connecting pin 11 and the guide plate 2, thereby reducing the vibration during the transmission process. Both ends of the limit rod 5 are threadedly connected to the limit plate, and the limit plate is used to prevent the limit rod 5 from falling off the guide plate 2.

[0033] Among them, the limit assembly also includes two groups of movable rods 9, and the first guide plate 21 and the second guide plate 22 are each provided with a third connecting hole 202. The movable rods 9 are respectively inserted into multiple third connecting holes 202, and the movable rods 9 are each provided with an anti-slip ring 10. The anti-slip ring 10 is respectively located between the two adjacent groups of first guide plates 21 and second guide plates 22. The anti-slip ring 10 located between the first guide plate 21 and the second guide plate 22 converts the rigid contact part between the guide plates 2 into a rigid-flexible contact part, thereby further reducing the vibration during the meshing process, effectively reducing the meshing noise, and thus reducing the possibility of sliding between the guide plates 2.

[0034] Finally, the limiting assembly also includes a connecting rod 6 hinged at both ends of the movable rod 9, and telescopic rods 7 are hinged on both sides of the end of the rectangular plate 3. The other end of the telescopic rod 7 is hinged to the top of the connecting rod 6. When the guide plate 2 rotates, the telescopic rod 7 hinged between the movable rod 9 and the rectangular plate 3 is extended and retracted according to the rotation of the guide plate 2.

[0035] Working principle: The toothed chain plate in the present invention is only one section of the entire toothed chain, which is used to illustrate the structure of the chain. The connection methods of the remaining sections are the same as this section. During the operation of the present invention, when the bottom of the guide plate 2 is engaged with the sprocket, the guide plate 2 rotates around the connecting pin 11. The limiting rod 5 located between the third guide plates 23 limits the rotation of the connecting pin 11, reducing the friction between the connecting pin 11 and the guide plate 2, thereby reducing the vibration during the transmission process. At the same time, the anti-slip ring 10 located between the first guide plate 21 and the second guide plate 22 converts the rigid contact part between the guide plates 2 into a rigid-flexible contact part. At this time, the telescopic rod 7 hinged between the movable rod 9 and the rectangular plate 3 is extended and retracted according to the rotation of the guide plate 2, thereby further reducing the vibration during the engagement process, effectively reducing the engagement noise, and thus reducing the possibility of sliding between the guide plates 2.

[0036] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
