Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The present embodiment provides a protection chain 100 capable of reducing noise as much as possible during use of the protection chain 100 while ensuring that wear of the protection chain 100 is within a receivable range, and with reference to fig. 1, the protection chain 10 includes: a plurality of chain plates 10, wherein the chain plates 10 symmetrically form the left side and the right side of the protection chain 100; a plurality of baffles 20, wherein the baffles 20 symmetrically form the upper and lower sides of the protection chain 100; an elastic plate 30 connecting adjacent two link plates 10, the elastic plate 30 having a width extending in a link plate thickness direction and a length extending in a protective chain length direction; wherein, a plurality of elastic plates 30 are connected with each other by a connecting member 50.
In the present embodiment, since the elastic plate 30 is connected between two adjacent link plates 10, the protection chain 100 can play a role of buffering during the movement. And because the elastic plate 30 has a width extending in the thickness direction of the link plate 10 and a length extending in the length direction of the protection chain, the contact area between the elastic plate 30 and the link plate 10 is increased, and the abrasion of the elastic plate 30 is effectively reduced.
In addition, a plurality of elastic plates 30 are connected by a connecting member 50, for example, five elastic plates 30 are connected into a set of elastic plates 30 by the connecting member 50 in fig. 1, and the connecting member 50 is provided on the inner plate portion 12 side of the elastic plates 30. This facilitates the assembly between the elastic plate 30 and the link plate 10, and avoids the problems of difficulty in counting and time-consuming assembly due to the scattering of a plurality of elastic plates 30. Of course, the number of the elastic plates 30 connected together by the connecting member 50 can be selected by those skilled in the art according to actual needs, and fig. 1 is only an exemplary connection manner.
In this embodiment, the coupling manner between the link plate 10 and the baffle plate 20, and between the link plate 10 and the elastic plate 30 are not limited, and may be a detachable coupling manner, an integrally formed non-detachable coupling manner, or different coupling manners for different parts of the protection chain 100.
Further, the elastic plate 30 has thickened portions 31 at both ends in the length direction thereof, and the thickened portions 31 are engaged with the notches 11 on the link plate 10 to connect the link plate 10 and the elastic plate 30. Due to the thickened portion 31 provided on the elastic plate 30, a fastening effect between the plurality of link plates 10 is achieved. Additional fasteners are removed, mitigating wear on the spring plate 30 and the protective chain 100.
Referring to fig. 1 and 3, the thickened portions 31 at the two ends of the elastic plate 30 have different shapes, and accordingly, the two notches 11 of the link plate 10 matched therewith also have different shapes. Specifically, the thickened portion 31 at one end of the elastic plate 30 is a round head, and the thickened portion 31 at the other end is a flat head, and a hook connected with the chain plate 10 can be attached to one end of the flat head.
In some preferred embodiments, the thickened portion 31 may be made of a material with a certain elastic deformation force, and may further play a role of buffering during the movement of the protection chain 100, so as to reduce noise.
Further, the middle of the elastic plate 30 may be bent. Since the middle of the elastic plate 30 is bendable, flexibility of the protection chain 100 during movement can be improved. The middle position of the elastic plate (broken line a in fig. 1) refers to the middle of both ends in the length direction of the elastic plate (i.e., the position where the thickened portion 31 is located), that is, the position between two adjacent link plates 10.
In some preferred embodiments, the elastic plate 30 is provided to be intermediately bendable in the length direction; has high tensile rigidity and bending rigidity in the width direction. This ensures flexibility of the protection chain 100 during movement, and improves the stability of the connection of the link plate 10 and the abrasion resistance of the elastic plate 30 itself.
Further, the link plates 10 include inner plate portions 12 and outer plate portions 13, and the inner plate portion 12 of one of the link plates 10 is overlapped with the outer plate portion 13 of the other link plate 10 in adjacent two link plates.
Since the link plates 10 include the inner plate portions 12 and the outer plate portions 13, the inner plate portion 12 of one of the link plates 10 is overlapped with the outer plate portion 13 of the other link plate 10 in the adjacent two link plates 10, so that the structure can increase the contact area between the two link plates 10, ensure the connection stability, reduce the pitch a (the distance between the central axes of the outer plate portions 13 of the two link plates), improve the smoothness of the protection chain 100 during the movement, and obtain the effect of reducing noise.
Furthermore, the upper and lower ends of the inner plate 12 are respectively provided with a connecting portion 121 perpendicular to the inner plate 12, the connecting portion 121 is provided with a protrusion 1211, the left and right ends of the baffle plate 20 are respectively provided with a hollow portion 21, and the protrusion 1211 is inserted into the hollow portion 21 to fix the chain plate 10 and the baffle plate 20.
The baffle 20 is connected with the inner plate 12 by the hollow part 21 on the baffle 20 and the projection 1211 on the connecting part 121 in a clamping way, so that the baffle is easy to open and convenient to detach. In addition, the connecting portion 121 having the projection 1211 is provided only on the inner plate portion 12, not extending to the outer plate portion 13, reducing the weight of the baffle plate 20, thereby reducing the overall weight of the protection chain 100, obtaining an effect of reducing noise.
Further, a plurality of partition plates 40 are arranged between the two opposite baffle plates 20 at intervals, and the partition plates 40 are adjustable partition plates 40.
Due to the fact that the plurality of adjustable partition plates 40 are arranged between the two opposite baffle plates 20 at intervals, the positions of the partition plates 40 can be adjusted according to actual requirements, and flexible pipe structures such as cables and electric wires can be guided in order. For example, when a large cable needs to be transported, the partition 40 between the upper and lower baffle plates 20 can be disassembled to obtain a larger inner space of the protection chain 100; when the thin wires need to be transported and guided, the distance between two adjacent partition boards 40 can be adjusted to prevent the wires from being twisted together.
Further, referring to fig. 2, the vertical distance (h1) between the elastic plate 30 and the upper baffle 20 is equal to the vertical distance (h2) between the elastic plate 30 and the lower baffle 20.
Because the elastic plate 30 is located at the middle height of the protection chain 100, the elastic plate 30 not only can play a role in buffering the protection chain 100 in the movement process, but also can be stably connected between the chain plates 10, thereby improving the compressive strength of the protection chain 100. The vertical distance between the elastic plate 30 and the upper baffle 20 is the vertical distance between the position of the elastic plate 30 closest to the upper baffle 20 and the upper baffle 20; the vertical distance between the elastic plate 30 and the lower baffle 20 refers to the vertical distance between the position of the elastic plate 30 closest to the lower baffle 20 and the lower baffle 20.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
