There are many types of chains, but their basic structures are only a few, and others are variations of these. Most chains are composed of chain plates, chain pins, bushings, and other components. Other types of chains simply modify the chain plates according to different needs. Some have scrapers installed on the chain plates, some have guide bearings installed on the chain plates, and some have rollers installed on the chain plates, etc. These are all modifications made for different applications. However, the current adjustable tension chain structure has the following problems: it is inconvenient for efficient buffering and is not conducive to efficient limiting. Summary of the Invention

[0003] The purpose of this invention is to provide an adjustable tension chain structure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an adjustable tension chain structure, comprising a first sprocket, a chain, and a second sprocket, wherein the chain is meshed on the second sprocket, and the first sprocket is meshed on the chain;

[0005] The chain is also meshed with a tension sprocket, and a docking shaft is rotatably mounted on the tension sprocket. The side end of the docking shaft is fixedly connected to the adjustment frame. A matching slide rod is fixedly connected to the center of the adjustment frame. The matching slide rod slides and adjusts on the limit slot seat. A control structure is docked at the front end of the adjustment frame, and a fixed guide rod is fixedly connected to the rear end of the control structure.

[0006] The control mechanism is used to guide the tension of the chain by cooperating with the slide bar and tension sprocket.

The first connecting frame is hinged to the mating hinge rod and the second connecting frame.

[0010] Specifically, the cooperating hinge and the second connecting frame are staggered, and the cooperating hinge and the second connecting frame are respectively hinged to the adjustment frames on the upper and lower sides.

[0011] Specifically, there are four tension sprockets that adjust the chain tension in the same direction.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By installing a fixed guide rod, which is fixed to the limiting slot seat, and a control structure is fixedly installed on the fixed guide rod, the control structure changes the position of the mating slide rod and the adjusting bracket by telescoping, so that the mating slide rod slides and adjusts on the limiting slot seat. At this time, the adjusting bracket drives the docking shaft and the tension sprocket to adjust accordingly, and the rear end of the mating slide rod slides on the limiting slot seat through the rod body, thereby performing the limiting and guiding work of the mating slide rod. At this time, the tension sprocket pushes the chain to perform the chain tension control work.

[0014] 2. By installing the control structure, the fixed support rod is used to fix the electric hydraulic telescopic rod. The electric hydraulic telescopic rod changes the position of the first connecting frame by telescoping. The first connecting frame is hinged with a matching hinge rod and a second connecting frame.

Detailed Implementation

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3. This utility model provides a technical solution: an adjustable tension chain structure, including a first sprocket 1, a chain 2, and a second sprocket 3. The chain 2 is meshed on the second sprocket 3, and the first sprocket 1 is meshed on the chain 2.

[0021] A tension sprocket 8 is also meshed on the chain 2. A connecting shaft 7 is rotatably mounted on the tension sprocket 8. The side end of the connecting shaft 7 is fixedly connected to the adjusting frame 6. A matching slide rod 4 is fixedly connected to the center of the adjusting frame 6. The matching slide rod 4 slides and adjusts on the limiting slot seat 5. A control structure 9 is connected to the front end of the adjusting frame 6. A fixed guide rod 10 is fixedly connected to the rear end of the control structure 9. By installing the fixed guide rod 10, the fixed guide rod 10 is fixed to the limiting slot seat 5. The control structure 9 is fixedly mounted on the fixed guide rod 10. The control structure 9 changes the position of the matching slide rod 4 and the adjusting frame 6 by extending and retracting, so that the matching slide rod 4 slides and adjusts on the limiting slot seat 5. At this time, the adjusting frame 6 drives the connecting shaft 7 and the tension sprocket 8 to adjust accordingly. The rear end of the matching slide rod 4 slides on the limiting slot seat 5 through the rod body, thereby performing the limiting and guiding work of the matching slide rod 4. At this time, the tension sprocket 8 pushes the chain 2 to perform the tension control work of the chain 2.

[0022] The control structure 9 is used to coordinate with the guide pulley 4 and the tension sprocket 8 to control the tension adjustment of the chain 2.

[0023] The limiting slot 5 provides fixed support, thereby limiting the movement of the sliding rod 4, allowing the sliding rod 4 to slide and adjust on the limiting slot 5.

[0024] An adjustment frame 6 is fixedly installed on the slide rod 4. Both ends of the adjustment frame 6 are equipped with tension sprockets 8 that rotate through the connecting shaft 7. The fixed guide rod 10 is fixedly connected to the limiting groove seat 5.

[0025] The control structure 9 includes a first connecting frame 11, a mating hinge rod 12, a second connecting frame 13, an electro-hydraulic telescopic rod 14, and a fixed support rod 15. The electro-hydraulic telescopic rod 14 is fixedly mounted on the fixed support rod 15. The first connecting frame 11 is fixedly connected to the front end of the electro-hydraulic telescopic rod 14. The mating hinge rod 12 and the second connecting frame 13 are hinged on the first connecting frame 11. By installing the control structure 9, the fixed support rod 15 is used to fix the electro-hydraulic telescopic rod 14. The electro-hydraulic telescopic rod 14 changes the position of the first connecting frame 11 by telescoping. The mating hinge rod 12 and the second connecting frame 13 are hinged on the first connecting frame 11. The mating hinge rod 12 and the second connecting frame 13 are connected to the adjustment frames 6 on the upper and lower sides. When the adjustment frames 6 are pulled, the mating slide rod 4 slides on the limiting groove seat 5, and the tension sprocket 8 follows the movement to control the compression of the chain 2.

[0026] The hinge rod 12 and the second connecting frame 13 are staggered and are respectively hinged to the upper and lower adjustment frames 6.

[0027] There are four tension sprockets 8, which adjust the tension of chain 2 in the same direction.

[0028] Working principle: During production, both the first sprocket 1 and the second sprocket 3 can be driven to control the rotation and transmission of the chain 2. When tension adjustment is required, the fixed support rod 15 fixed on the fixed guide rod 10 supports the electro-hydraulic telescopic rod 14. The electro-hydraulic telescopic rod 14 extends and adjusts, changing the position of the first connecting frame 11. This causes the first connecting frame 11 to pull the cooperating hinge rod 12 and the second connecting frame 13 to move laterally. The cooperating hinge rod 12 and the second connecting frame 13 are respectively connected to the adjusting frame 6 symmetrically arranged at the upper and lower ends, pushing the adjusting frame 6 to move. This causes the cooperating slide rod 4 to follow the movement. The cooperating slide rod 4 slides at the upper limit of the limiting groove seat 5, providing support. At this time, the adjusting frame 6 drives the docking shaft 7 and the tensioning sprocket 8 to move together. The four tensioning sprockets 8 move in the same direction, compressing the chain 2, thereby controlling the tension of the chain 2 and completing the work.
