Description

Technical Field

[0001] The utility model relates to the technical field of drag chains, in particular to a magnetic attraction module for a drag chain. Background Art

[0002] Drag chains are a common mechanical device that is often used to power the source of moving machinery such as ladder trucks and provide data signal connections. They can also protect cables while providing power.

[0003] During use, drag chains can experience swinging and wiggling. Specifically, they are affected by inertia, their own weight, the weight of the cables they carry, and the movement of the chain itself and the overall mechanism, causing them to move outside their intended trajectory. This can cause the chain to extend beyond its designated area, potentially causing it to jam or break, or even scratch other mechanical structures, resulting in serious consequences.

[0004] Existing solutions often rely on baffles, guide grooves, or other guide mechanisms to restrict the trajectory of the drag chain. However, due to the overall mechanical structure and the available space on site, the size and installation space of the guides are also very limited. This sometimes fails to completely restrict the drag chain, and risks cannot be completely avoided. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art and provide a drag chain magnetic module that can be used to fix the drag chain and limit its trajectory.

[0006] In order to achieve the above-mentioned purpose, the drag chain magnetic module of the present invention has the following structure:

[0007] The drag chain magnetic module includes a sheath and a magnet. The sheath includes a base plate, side plates arranged on the side of the base plate, and magnet embedding grooves arranged between the side plates. The magnet is embedded and fixed in the magnet embedding groove and abuts against the base plate. The top of the side plate has a drag chain connector.

[0008] In the drag chain magnetic module, the bottom plate is a rectangular bottom plate, the side plates are arranged around the bottom plate, and the tops of two opposite side plates are provided with the drag chain connectors.

[0009] In the drag chain magnetic module, four-side positioning ribs are provided within the area enclosed by the side panels, and rectangular magnet embedding grooves are provided within the four-side positioning ribs, and the bottom surface of the magnet embedding grooves is the bottom plate.

[0010] In the drag chain magnetic module, the drag chain connector is a plurality of protruding pieces respectively provided on the top of two opposite side panels, and the drag chain magnetic module is fastened to the crossbar of the drag chain by the protruding pieces.

[0011] The drag chain magnetic module also includes a disassembly hole passing through the bottom plate, and the position of the disassembly hole corresponds to the position of the drag chain connector.

[0012] In the drag chain magnetic module, several cross bars on one side of the drag chain are fixed with corresponding drag chain magnetic modules, and are adsorbed and fixed to the external sheet metal surface through each of the drag chain magnetic modules, and the bottom plate is located between the magnet and the external sheet metal surface.

[0013] The utility model employs a drag chain magnetic module, which includes a sheath and magnets. The sheath comprises a base plate, side plates disposed on the sides of the base plate, and magnet insertion slots disposed between the side plates. The magnets are embedded and fixed in the magnet insertion slots and abut against the base plate. The tops of the side plates have drag chain connectors. Multiple drag chain magnetic modules are secured to various locations on the drag chain via the drag chain connectors. Magnets are attached to the desired drag chain locations to secure the drag chain and confine it to a trajectory formed by the attachment points of the magnetic modules. This prevents the drag chain from exceeding the designated area, causing it to become stuck, break, or scrape against other mechanical structures. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to more clearly understand the technical content of the present invention, the following embodiments are given to explain in detail.

[0027] See also Figure 1 , which is a structural diagram of the drag chain magnetic module of the present invention.

[0028] In one embodiment, Figures 1 to 4 As shown, the drag chain magnetic module 1 includes a sheath 11 and a magnet 12. The sheath 11 includes a base plate 13, side plates 14 arranged on the side of the base plate 13, and magnet embedding grooves 15 arranged between the side plates 14. The magnet 12 is embedded and fixed in the magnet embedding grooves 15 and abuts against the base plate 13. The top of the side plate 14 has a drag chain connector 16.

[0029] In a more preferred embodiment, the bottom plate 13 is a rectangular bottom plate, and the side plates 14 are arranged around the bottom plate 13 , wherein the drag chain connectors 16 are arranged on the tops of two opposite side plates 14 .

[0030] In another preferred embodiment, four-side positioning ribs 17 are provided within the enclosed area of ​​the side panels 14 , and rectangular magnet embedding slots 16 are provided within the four-side positioning ribs 17 , and the bottom surface of the magnet embedding slots 16 is the bottom panel 13 .

[0031] In a further preferred embodiment, Figure 5 、 6 As shown, the drag chain connector 16 is a plurality of protrusions respectively provided on the top inner sides of two opposite side panels 14 , and the drag chain magnetic module 1 is fastened and fixed to the crossbar 21 of the drag chain 2 through the protrusions.

[0032] Further, such as Figures 1 to 3 As shown, the drag chain magnetic module 1 also includes a disassembly hole 18 that passes through the bottom plate 13. The disassembly hole 18 is in a long strip shape and its position corresponds to the position of the drag chain connector 16. When it is necessary to remove the drag chain magnetic module 1 from the crossbar 21 of the drag chain 2, a tool such as a screwdriver can be used to remove it. Figure 3 The back side of the protective cover 11 is inserted into the disassembly hole 18 , and the magnetic module 1 of the drag chain is pried open from the position where the protruding piece and the cross bar are buckled, so as to facilitate disassembly.

[0033] In a more preferred embodiment, a plurality of crossbars 21 on one side of the drag chain 2 are fixed with corresponding drag chain magnetic modules 1, and are fixed to the surface of the external sheet metal 3 by adsorption of each of the drag chain magnetic modules 1, and the bottom plate 13 is located between the magnet 12 and the surface of the external sheet metal 3. Figure 3 As shown, the back of the drag chain magnetic module 1 may further include a shock-absorbing strip 19 , which is used to reduce vibration during the adsorption process when the drag chain 2 is adsorbed and fixed to the surface of the external sheet metal 3 through the drag chain magnetic module 1 .

[0034] Thus, a plurality of the drag chain magnetic modules 1 can be fixed to various locations of the drag chain 2 through the drag chain connectors 16 , and at the same time, the magnets 12 are adsorbed on the locations where the drag chain 2 is to be set to fix the drag chain 2 .

[0035] When Figure 5 When the column shown has a lateral high-speed displacement, the drag chain 2 can also be adsorbed on the column (external sheet metal 3) without shaking, and at the same time does not affect the movement of the drag chain itself.

[0036] When Figure 6 As shown, the drag chain 2 is adsorbed on the top structure (external sheet metal 3). Even if the drag chain 2 is affected by its own gravity, it will not sag and will not affect the movement of the drag chain itself.

[0037] like Figure 7 and Figure 8 The following are schematic diagrams of the front and back structures of the second alternative embodiment of the drag chain magnetic module of the present invention. The difference from the previous embodiment is that the drag chain connectors are located at the four corners, with the disassembly holes located correspondingly, and the side panels directly enclose the magnet insertion slots.

[0038] like Figure 9 and Figure 10 The figure shows the front structure of the cover of the third alternative embodiment of the drag chain magnetic module of the present invention. It differs from the previous two embodiments in that a fastening strip extending along the length of the top of the side panel is used instead of the drag chain connector, eliminating the need for a disassembly hole. The fastening strip is used to secure the cover to the drag chain's crossbar.

[0039] Compared with the baffle structure used in the prior art, the use of the drag chain magnetic module of each embodiment of the present invention can greatly reduce design time and save design and application costs.

[0040] In practical applications, the drag chain magnetic module of this utility model consists of a sheath and a magnet or magnet. The module is installed and fastened to the drag chain's crossbar, firmly securing the magnet / magnet to prevent it from shaking. This allows the drag chain to adhere to external sheet metal materials such as carbon steel, thereby maintaining the drag chain's trajectory.

[0041] The characteristics of the drag chain magnetic module of this utility model are:

[0042] 1. Does not affect the movement of the drag chain and does not increase the horizontal width of the drag chain;

[0043] 2. Wear-resistant and durable, not easy to fall off during work, easy to install, dismantle and maintain;

[0044] 3. It is easy to control the magnetic attraction strength by adjusting the number of installed magnetic modules;

[0045] 4. Less impact noise;

[0046] 5. It can be produced by 3D printing and injection molding, and can be adjusted according to quantity, which is convenient for production and manufacturing;

[0047] 6. Different specifications and sizes can be manufactured to suit different specifications of drag chains.

[0048] The utility model employs a drag chain magnetic module, which includes a sheath and magnets. The sheath comprises a base plate, side plates disposed on the sides of the base plate, and magnet insertion slots disposed between the side plates. The magnets are embedded and fixed in the magnet insertion slots and abut against the base plate. The tops of the side plates have drag chain connectors. Multiple drag chain magnetic modules are secured to various locations on the drag chain via the drag chain connectors. Magnets are attached to the desired drag chain locations to secure the drag chain and confine it to a track formed by the attachment points of the magnetic modules. This prevents the drag chain from exceeding the designated area, causing it to become stuck, break, or scrape against other mechanical structures.

[0049] In this specification, the present invention has been described with reference to specific embodiments thereof. However, it will be apparent that various modifications and variations may be made without departing from the spirit and scope of the present invention. Accordingly, the specification and drawings are to be regarded as illustrative rather than restrictive.
