[0017] Description of the Reference Numerals in the Drawings:

[0019] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.
[0020] In order to better understand the above technical solution, the exemplary embodiments of the present invention will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to be able to convey the scope of the present invention completely to those skilled in the art.
[0021] In order to better understand the above technical solution, the above technical solution will be described in detail below in combination with the drawings of the specification and the specific embodiments.
[0022] Reference will be made below Figure 1-2 to describe in detail the implementation of the drag chain support device according to the embodiments of the present invention.
[0023] The drag chain support device according to the embodiments of the present invention includes: a first rolling member 1 and a support 2.
[0024] Specifically, the first rolling member 1 is rotatably and elastically telescopicly disposed on the support 2 to elastically abut against the bottom of the drag chain 4 from the bottom of the drag chain 4 and rotate following the dragging of the drag chain 4.
[0025] That is to say, during the rapid back-and-forth dragging of the drag chain 4, the drag chain 4 will float up and down. By elastically abutting the bottom of the drag chain 4 with the first rolling member 1, the dragging can be supported and rotated following the dragging of the drag chain 4. Not only can the drag chain 4 be smoothly dragged, but also when the first rolling member 1 is worn or the drag chain 4 floats up and down, it can float and fit to support the drag chain 4, ensuring the service life of the drag chain 4.
[0026] Thus, the bottom of the drag chain 4 can be elastically telescopicly abutted by the first roller to float and fit the bottom of the drag chain 4 when the drag chain 4 is dragged, thereby supporting the drag chain 4 and ensuring the service life of the drag chain 4.
[0027] For the support 2, the support 2 includes two oppositely arranged chutes 21. The two ends of the first rolling member 1 are correspondingly connected to the two chutes 21, and an elastic member 22 for making the first rolling member 1 elastically telescopic is provided in the chute 21. It can be understood that by correspondingly connecting the two ends of the first rolling member 1 to the chute 21, it is convenient to improve the support strength of the first rolling member 1. By providing the elastic member 22 for making the first rolling member 1 elastically telescopic in the chute 21, it is convenient for the first rolling member 1 to elastically support the drag chain 4 and ensure the service life of the drag chain 4.
[0028] For the support 2, the support 2 includes a bottom plate 23 and two columns 24. The bottom plate 23 and the two columns 24 are detachably connected. The sliding grooves 21 are respectively arranged on the two columns 24, and the lower ends of the sliding grooves 21 penetrate through the lower ends of the columns 24. One end of the elastic member 22 abuts against the first rolling member 1, and the other end of the elastic member 22 abuts against the bottom plate 23. It can be understood that, through the detachable arrangement of the bottom plate 23 and the columns 24 and the lower ends of the sliding grooves 21 penetrating through the lower ends of the columns 24, it is convenient to load the first rolling member 1 into the sliding groove 21 from the penetration of the sliding groove 21, so as to facilitate the quick assembly of the first rolling member 1 and the support 2; through the arrangement of the elastic member 22, it is convenient for the first rolling member 1 to elastically slide in the sliding groove 21, so as to facilitate the first rolling member 1 to float and fit the drag chain 4 and support the drag chain 4. Among them, the elastic member 22 can be a spring. The column 24 has an installation space for the deformation of the spring along its length direction. This installation space communicates with the sliding groove 21. The cross section of this installation space can be in a quasi-circular shape. The matching parts of the two ends of the first rolling member 1 and the sliding groove 21 can be in a rectangular shape.
[0029] For the limitation when the drag chain 4 floats upward, it further includes a second rolling member 3. The second rolling member 3 is rotatably connected to the support 2 and is located above the drag chain 4. When the top of the drag chain 4 touches and drags the second rolling member 3, the second rolling member 3 can be driven to rotate. It can be understood that since the drag chain 4 will also arch upward when it is dragged at high speed, through the arrangement of the second rolling member 3, it is convenient for the drag chain 4 to roll and contact the top of the drag chain 4 when it arches, so as to limit the drag chain 4 to drag between the first rolling member 1 and the second rolling member 3. The service life of the drag chain 4 is guaranteed, and at the same time, it is avoided that the drag chain 4 makes noise when it drags and touches the sheet metal or the shield, etc. Among them, when the drag chain 4 is in a stopped state, the second rolling member 3 can have a gap with the top of the drag chain 4.
[0030] For the floating of the second rolling member 3, the second rolling member 3 is connected to the first rolling member 1 so that the second rolling member 3 synchronously elastically expands and contracts with the first rolling member 1. The first rolling member 1 and the second rolling member 3 jointly construct a limiting space to limit the drag chain 4 to drag in the limiting space. It can be understood that by connecting the second rolling member 3 to the first rolling member 1, the second rolling member 3 can synchronously expand and contract with the first rolling member 1, so as to form a floating limiting space and limit the drag chain 4 to drag in the limiting space, thereby guaranteeing the service life of the drag chain 4. Among them, the first rolling member 1 and the second rolling member 3 can be made of metal or non-metal materials, such as nylon, rubber, etc.
[0031] For the floating of the second rolling member 3, the second rolling member 3 includes two connecting members 31. The two connecting members 31 pass through the two columns 24 one by one and are connected to the first rolling member 1, so that the second rolling member 3 is connected to the first rolling member 1. It can be understood that through the arrangement of the connecting members 31, the installation of the second rolling member 3 and the first rolling member 1 can be facilitated, thereby forming a synchronous telescopic function; by passing the connecting members 31 through the columns 24 to connect the first rolling member 1, it is convenient to improve the connection strength between the second rolling member 3 and the support 2, thereby ensuring the service life of the second rolling member 3. At the same time, the connecting members 31 can also limit the left-right yaw of the drag chain 4 during dragging. Among them, the connecting members 31 can be cylindrical, and the connection between the connecting members 31 and the first rolling member 1 can be detachable, which is convenient for assembly and replacement.
[0032] For the first rolling member 1 and the second rolling member 3, the first rolling member 1 and the second rolling member 3 are elastic rollers. It can be understood that since both surfaces of the drag chain 4 are concave-convex, when the drag chain 4 comes into contact with the first rolling member 1 and the second rolling member 3 during dragging, a relatively large noise will be generated. Through the arrangement of the elastic rollers, it is convenient to reduce the noise generated during the dragging of the drag chain 4, and rollers made of sponge material can also be used.
