It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the utility model. The present invention will be described in detail with reference to the following specific examples:

example 1

Fig. 1 is a schematic diagram of an exploded structure of a drag chain structure for a mud scraper according to an embodiment of the present invention.

In the present embodiment, the traction chain used in the mud scraper has a structure as shown in fig. 1. As can be seen with reference to fig. 1, the traction chain structure comprises a link body 1, a detachable connection piece 2 and a fixed catch 3.

While reference is made to figures 2 to 7 as regards the specific structure of the link body 1, the detachable connection 2 and the fixed catch 3.

Fig. 2 is a schematic front structural view of a chain link of a traction chain structure for a mud scraper in one embodiment of the utility model; fig. 3 is a schematic side view of a chain link of one embodiment of the drag chain structure for the mud scraper of the present invention.

As shown in fig. 2 and 3, the link body 1 is composed of a left chain plate, a right chain plate and a roller, and the three are formed into an integral chain link through a non-metallic material injection molding process.

The left and right link plates form a first link member 11 and a second link member 12 which are oppositely arranged, and the roller forms a fixed end 14, so that the first link member 11 is fixedly connected with the second link member 12 through the fixed end 14. As can be seen with further reference to fig. 2 and 3, the first link element 11 has a first outer surface I and a first inner surface opposite the first outer surface. And, in contrast, the second link member 12 has a second outer surface and a second inner surface II opposite the second outer surface, the second inner surface II being disposed opposite the first inner surface.

Furthermore, a rib 16 is provided on the first outer surface in the axial direction of the first link member 11, and the rib 16 is provided to reinforce the strength thereof. And first chain link spare 11 and second chain link spare 12 all are equipped with connecting hole 13 at the tip of keeping away from stiff end 14, and the two difference lies in first chain link spare 11 still is equipped with draw-in groove 15 at the tip that is close connecting hole 13, and draw-in groove 15 is located on first surface I, and detachable connecting piece 2 joint is on draw-in groove 15.

Reference is made to fig. 4 and 5 for the structure of the detachable connection 2, wherein fig. 4 is a schematic perspective view of the detachable connection in one embodiment of the drag chain structure for a mud scraper according to the present invention; fig. 5 is a schematic top view of a detachable connecting member of a drag chain structure for a mud scraper according to an embodiment of the present invention.

As can be seen from fig. 4 and 5, the detachable connecting member 2 is a bolt, and one end of the detachable connecting member 2 is provided with a plug 15 matched with the slot 15, so that the detachable connecting member 2 is inserted into the connecting hole 13 to fix the ends of the first chain link member 11 and the second chain link member 12 away from the fixed end 14 (i.e. the ends close to the connecting hole 13), and preferably, the diameter of the detachable connecting member 2 is slightly smaller than the aperture of the connecting hole 13 by 0.1-4 mm, so that the chain links can rotate freely around the bolt axis.

It should be noted that the matching means that the plug 21 can be just locked in the slot 15. The plug 21 is not easy to be too large, otherwise, the plug is difficult to be clamped into the clamping groove 15; and the size of the connecting piece 2 is not too small, so that too much clearance is left between the plug 21 and the clamping groove 15 due to the fact that the plug 21 is too small, and the whole chain is easy to rotate axially in the clearance due to the fact that the connecting piece 2 can be disassembled in the operation process.

As can be seen from the combination of FIG. 2 and FIG. 4, the size of the bayonet 15 on the first link member 11 is slightly larger than that of the plug 21, and the difference is 0-1.0 mm.

As can be seen from fig. 6 and 7, the traction chain structure further includes a fixing buckle 3, and the fixing buckle 3 is clamped on the detachable connecting member 2 to fix the detachable connecting member 2. Specifically, in the present embodiment, the fixing clip 3 includes a clip body 31, and an upper end surface of the clip body 31 has a port 32, and the port 32 is used for manually pulling and inserting the fixing clip 3, so as to facilitate on-site construction. In addition, the fixed buckle 3 is provided with a first positioning element (i.e. the annular groove 33 and the boss 34) at the connection position of the fixed buckle and the detachable connector 2, and the first positioning element is matched with a second positioning element (i.e. the pin salient point 22 and the annular dent 23) arranged on the detachable connector 2 so as to fix the position of the fixed buckle 3 relative to the detachable connector 2.

In particular, the annular groove 33 of the fixed catch 3 can be tightly engaged with the annular indentation 23 to secure the detachable connection 2 to the fixed catch 3 well.

In this embodiment, the fixed end 14 of the drag chain structure can be connected with the connecting hole 13 of another drag chain structure when the drag chain structure is used, especially assembled, that is, the structure is connected end to end.

And the detachable connecting piece 2 is inserted into the connecting hole 13, and the plug 21 is closely matched with the clamping groove 15. The other end of the detachable connection 2 is clamped at its annular indentation 23 by means of the fixing catch 3. And, when fixed buckle 3 is blocked in annular groove 33, annular groove 33 just can closely interlock with bolt bump 22, and boss 34 is closely laminated with the wall of annular groove 33 simultaneously, forms powerful support, prevents to dismantle connecting piece 2 radial displacement in connecting hole 13.

And the disassembly process of the traction chain structure is just opposite to the assembly process, the fixed buckle 3 is firstly pulled out, the detachable connecting piece 2 is pulled out, and the disassembly of the chain is completed.

It should be noted that, among the above technical scheme, chain link body 1, detachable connecting piece 2 and fixed buckle 3 are all non-metallic material and pass through injection moulding technology machine-shaping, have simple structure, processing is convenient, and size precision is high, and the technology is stable, and the raw materials is extravagant advantage such as few.

In conclusion, the traction chain structure is formed by assembling three components, namely the chain link body, the detachable connecting piece and the fixed buckle, is few in component types and easy to identify, and avoids the phenomena of less assembly, neglected assembly, wrong assembly and the like caused by excessive components. Simultaneously, the present case carries out special design and optimization through chain link body in to the chain, the structure of dismantling connecting piece and fixed buckle for can closely firmly be fixed together between the three, prevent that the chain from taking off, landing in the operation process. Meanwhile, the chain is very convenient to assemble and disassemble, special auxiliary tools are not needed, the working efficiency of the site is greatly improved, and the labor intensity of workers and the later maintenance cost are reduced.

In addition, the traction chain structure of the scheme also has the following advantages: the component types are few and easy to identify; the chain is very convenient to assemble and disassemble, special auxiliary tools are not needed, the working efficiency of the site is greatly improved, and the labor intensity of workers and the later maintenance cost are reduced.
