Abstract
Description
Technical Field
[0001] This utility model relates to the field of horizontal drawing machine chain technology, specifically a horizontal drawing machine chain that is easy to assemble and disassemble. Background Technology
[0002] Chains are generally metal links or rings, mostly used for mechanical transmission and traction. They can also be used as chain-like objects to obstruct traffic (such as in streets, river or harbor entrances), or as chains for mechanical transmission. Chain products are classified according to their basic structure, that is, based on the shape of the components, the parts and locations that mesh with the chain, and the dimensional proportions between the parts.
[0003] According to a publicly disclosed chain that is easy to disassemble (publication number: CN221704316U), the above application directly installs and locks the mounting block and mounting groove inside a chain plate. The middle part of the two chain plates is a connecting plate that can be inserted. Moreover, the beginning and end of the chain can be disassembled by simply removing the mounting block and fixing screw. While satisfying the requirements of easy disassembly, it is also more secure in use.
[0004] However, in actual use, the above-mentioned equipment has fixed chain link or fixing frame size, which cannot be adapted to chains of different diameters or specifications. Multiple sets of equipment need to be prepared for different tasks, which increases costs and storage space. The chain fixing frame size is not adjustable, which means that one set of equipment can only be adapted to chains of specific specifications, resulting in poor versatility and frequent replacement. In view of this, we propose a cross-thread machine chain that is easy to assemble and disassemble. Utility Model Content
[0005] The purpose of this invention is to provide a convenient assembly and disassembly chain for a horizontal pulling machine, in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a conveniently detachable and assembled horizontal pulling machine chain includes a fixing frame, and the side wall of the fixing frame is provided with an adaptive chain size adjustment mechanism, the adjustment mechanism including:
[0007] A sliding groove is formed on the side wall of the fixed frame. A first telescopic spring is fixedly connected to the bottom surface of the sliding groove. A sliding rod is fixedly connected to the end of the first telescopic spring away from the fixed frame. A mounting plate is fixedly connected to the end of the sliding rod away from the first telescopic spring.
[0008] The first slot is located at one end of the mounting plate near the fixing frame, and a connecting plate is rotatably connected to the end of the first slot near the fixing frame. The connecting plate has a second slot at one end near the fixing frame.
[0009] Preferably, the ends of the mounting plate and the connecting plate are both arc-shaped, and the first slot and the second slot are both semi-circular in shape.
[0010] Preferably, there are two sets of sliding grooves, which are mirror-symmetrically arranged on the outer walls of both ends of the fixed frame, and the outer wall of the sliding rod is slidably connected to the inner wall of the sliding groove.
[0011] Preferably, the fixing frame is provided with a fixing mechanism that connects multiple fixing frames in conjunction with the adjustment mechanism. The fixing mechanism includes a mounting groove, a telescopic rod is fixedly connected to the bottom surface of the mounting groove, a second telescopic spring is sleeved on the outer surface of the telescopic rod, a fixing sleeve is fixedly connected to the end of the telescopic rod away from the fixing frame, and a fixing bolt is threadedly connected to the inner wall of the fixing sleeve.
[0012] Preferably, the outer diameter of the head of the fixing bolt is larger than the opening size of the fixing sleeve, and the end of the connecting plate away from the fixing frame has a slot whose size matches that of the fixing bolt.
[0013] Preferably, both the mounting plate and the connecting plate have through holes on their outer walls, and the inner wall of the through hole in the connecting plate abuts against the outer wall of the fixing sleeve.
[0014] Preferably, the number of fixing frames is provided in multiple sets, and the multiple sets of fixing frames are detachably connected by connecting plates and fixing bolts, and both ends of the fixing frames are set to be arc-shaped.
[0015] Compared with the prior art, this utility model provides a convenient assembly and disassembly chain for a horizontal pulling machine, which has the following advantages:
[0016] 1. This easy-to-assemble and disassemble horizontal pulling machine chain, through the setting of an adjustment mechanism, in conjunction with a slide groove, a first telescopic spring and a slide rod, allows the mounting plate to slide elastically along the side wall of the fixed frame, thereby driving the connecting plate to automatically adjust its position. Through the movable connecting plate and mounting plate, the chain can adapt to work objects of different sizes. When subjected to changes in external dimensions, it maintains a close fit through spring buffering. At the same time, the abutment of the connecting plate further enhances the adaptability of the chain, improves the flexibility of installation and compatibility with different working conditions.
[0017] 2. This easily detachable horizontal pulling machine chain, through the setting of a fixing mechanism, in conjunction with the elastic cooperation of the telescopic rod, the second telescopic spring and the fixing sleeve, allows multiple fixing frames to be quickly connected and locked through fixing bolts. This not only realizes the detachable assembly of multiple fixing frames, facilitating flexible adjustment and partial replacement of the chain length, but also allows the elastic element to work with the adjustment mechanism to provide a tight connection between the mounting plate and the connecting plate to the fixing frame, enhancing the stability and durability of the overall chain connection and simplifying the maintenance and assembly process.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a conveniently detachable and assembled horizontal pulling machine chain, including a fixed frame 1. The side wall of the fixed frame 1 is provided with an adaptive chain size adjustment mechanism 2. The adjustment mechanism 2 includes: a slide groove 21, a first telescopic spring 22, a slide rod 23, a mounting plate 24, a first slot 25, a connecting plate 26, and a second slot 27.
[0024] In one embodiment of this utility model, a sliding groove 21 is formed on the side wall of the fixed frame 1. A first telescopic spring 22 is fixedly connected to the bottom surface of the sliding groove 21. A sliding rod 23 is fixedly connected to the end of the first telescopic spring 22 away from the fixed frame 1. A mounting plate 24 is fixedly connected to the end of the sliding rod 23 away from the first telescopic spring 22. A first slot 25 is formed at the end of the mounting plate 24 near the fixed frame 1, and a connecting plate 26 is rotatably connected to the end of the first slot 25 near the fixed frame 1. A second slot 27 is formed at the end of the connecting plate 26 near the fixed frame 1. The ends of the mounting plate 24 and the connecting plate 26 are both arc-shaped, and the shapes of the first slot 25 and the second slot 27 are both semi-circular. Two sets of sliding grooves 21 are provided, and the two sets of sliding grooves 21 are mirror-symmetrically arranged on the outer walls of both ends of the fixed frame 1. The outer wall of the sliding rod 23 is slidably connected to the inner wall of the sliding groove 21. When subjected to external pressure, the mounting plate 24 and connecting plate 26 are forced to retract the slide rod 23 along the slide groove 21, compressing the first telescopic spring 22. This creates a self-adjusting space. Furthermore, the ends of the mounting plate 24 and connecting plate 26 are both arc-shaped, allowing the chain to rotate more smoothly. The semi-circular first and second slots 25 and 27 can cooperate with the arc-shaped mounting plate 24 and connecting plate 26, making the overall chain operation smoother. Additionally, the outer wall of the slide rod 23 slides against the inner wall of the slide groove 21, preventing external oil and impurities from entering the slide groove 21 and protecting the first telescopic spring 22. The mounting plates 24 and connecting plates 26 on both sides allow for self-adjusting on both sides, further expanding the adjustment range of the mounting plates 24 and connecting plates 26.
[0025] Additionally, the mounting bracket 1 is internally equipped with a fixing mechanism 3 that connects multiple sets of mounting brackets 1 in conjunction with the adjustment mechanism 2. The fixing mechanism 3 includes a mounting groove 31, with a telescopic rod 33 fixedly connected to the bottom surface of the mounting groove 31. A second telescopic spring 32 is sleeved on the outer surface of the telescopic rod 33. A fixing sleeve 34 is fixedly connected to the end of the telescopic rod 33 away from the mounting bracket 1. A fixing bolt 35 is threadedly connected to the inner wall of the fixing sleeve 34. The outer diameter of the head of the fixing bolt 35 is larger than the opening size of the fixing sleeve 34. Furthermore, a slot with a size matching the fixing bolt 35 is provided at the end of the connecting plate 26 away from the mounting bracket 1. When the mounting plate 24 and the connecting plate 26 move... When in motion, it can synchronously drive the fixing bolt 35 to move. In conjunction with the second telescopic spring 32 and the fixing sleeve 34 set in the slot, it can follow the movement of the mounting plate 24 and the connecting plate 26, dynamically connecting with the fixing bolt 35 to maintain the integrity and tightness of the chain connection. The outer diameter of the head of the fixing bolt 35 is larger than the opening size of the fixing sleeve 34, so that the fixing bolt 35 can squeeze the connecting plate 26. Then, the mounting plate 24 is connected and fixed through the first slot 25 and the second slot 27. The fixing bolt 35 can be threaded to the inner wall of the fixing sleeve 34 through the through hole to complete the stable connection of the mounting plate 24 and the connecting plate 26.
[0026] In this embodiment of the utility model, both the mounting plate 24 and the connecting plate 26 have through holes on their outer walls. The through holes are used to install fixing bolts 35. The inner wall of the through hole in the connecting plate 26 abuts against the outer wall of the fixing sleeve 34, so that the inner wall of the connecting plate 26 and the outer wall of the fixing sleeve 34 will not affect the normal operation of the chain. Multiple sets of fixing frames 1 are provided. Multiple sets of fixing frames 1 are detachably connected to the connecting plate 26 and the fixing bolts 35. Multiple sets of fixing frames 1, together with the connecting plate 26, the mounting plate 24 and the fixing bolts 35, can form a complete chain. Through the design of the first slot 25 and the second slot 27, the outer surfaces of the mounting plate 24 and the connecting plate 26 can be flush, reducing unnecessary friction between the chain and the equipment during operation. Both ends of the fixing frame 1 are set as arcs. The arc-shaped fixing frame 1 can better adapt to different working environments and reduce wear during operation. The fixing bolts 35 are existing models, which makes it easier to install and remove the fixing bolts 35.
[0027] In this invention, during use, multiple fixing frames 1 cooperate with the internal fixing mechanism 3 through the adjustment mechanism 2 on their sides to form a detachable and adaptive continuous chain structure. When installing the chain, the chain body acts on the first slot 25 of the mounting plate 24 and the second slot 27 of the connecting plate 26, forcing the mounting plate 24 to drive the slide rod 23 to retract along the slide groove 21 and compress the first telescopic spring 22, thereby providing adaptive adjustment space. The fixing sleeve 34, the second telescopic spring 32 and the telescopic rod 33 in the fixing mechanism 3 will work together to make the fixing bolt 35 dynamically aligned with the slot on the connecting plate 26 of the adjacent fixing frame 1 and locked, thereby firmly connecting multiple fixing frames 1 to form a complete working chain that is both tight and flexible to adapt to the chain state.
[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
