Description

Technical Field

[0001] The utility model relates to the technical field of acrylic plate thermoforming, in particular to a crankshaft connecting rod assembly. Background Art

[0002] Crankshaft connecting rods are mostly used inside the engine. After the fuel is ignited inside the engine, friction between these parts will produce iron filings.

[0003] Application number CN202121835150.6 discloses a crankshaft connecting rod assembly with an embedded magnetic block, which relates to the field of crankshaft connecting rod technology, including two sets of crankshaft mechanisms with the same structure. This application allows the magnetic block to collect iron filings by adsorption to prevent wear of internal parts caused by iron filings. However, during specific use, since the magnet is completely sealed by the cover assembly, the magnetically attracted debris can only remain on the surface of the cover, and then the connecting rod assembly will inevitably rub against these debris when it is moving, and then wear will occur, which threatens the service life of the entire structure.

[0023] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0024] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0025] A crankshaft-connecting rod assembly provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings. Embodiment 1

[0026] Combination Figure 1-4 As shown, the present invention provides a crankshaft-connecting rod assembly, including a linkage module 100 and a magnetic attraction module 200, wherein the linkage module 100 includes two crankshafts 110, a connecting shaft 120 connected between the two crankshafts 110, and a connecting rod 130 movably sleeved on the outside of the connecting shaft 120;

[0027] The magnetic attraction module 200 includes a shallow groove 210 opened on the inner side of the crankshaft 110, a magnet 220 installed in the shallow groove 210, a plate frame 230 arranged in the shallow groove 210 and fitted with the magnet 220, two plate sleeves 240 installed on both sides of the plate frame 230, a plug-in plate 250 movably plugged with the plate sleeve 240, two springs 260 connected between the plate sleeve 240 and the plug-in plate 250, and a magnet 270 installed on the inner side of the plate frame 230, the plug-in plate 250 is plugged with the inner wall of the crankshaft 110, the magnet 270 is located on the outer side of the magnet 220, and the spring 260 is located on the inner side of the plate sleeve 240.

[0028] Furthermore, the connecting rod 130 is located between the two crankshafts 110 and fits against the inner side of the crankshaft 110 . With this structural design, the movement of the connecting rod 130 is more stable.

[0029] Furthermore, the plate frame 230 , plate sleeve 240 , and plug plate 250 are all made of insulating metal materials. Using the same metal materials can reduce the difficulty of material selection when manufacturing the plate frame 230 , plate sleeve 240 , and plug plate 250 .

[0030] Furthermore, a protrusion is integrally formed on the front side of the plug plate 250, and a sliding groove suitable for the sliding of the protrusion is opened on the front side of the plate sleeve 240. The protrusion is provided to facilitate the staff to retract multiple plug plates 250, so that the plate frame 230 can be more easily installed into the shallow groove 210. Embodiment 2

[0031] Combination Figure 1-2 As shown, on the basis of the first embodiment, circular thin sheets are integrally formed at both ends of the connecting shaft 120, and the diameter of the circular thin sheets is larger than the diameter of the connecting shaft 120. The provision of the circular thin sheets can prevent the connecting shaft 120 from falling off from the two crankshafts 110, making the structure of the device more stable and firm. Embodiment 3

[0032] Combination Figure 3-4 As shown, in the above embodiment, the plate frame 230 is composed of a square piece and a plurality of short shafts, and the plurality of short shafts are welded in a matrix on the inner side of the square piece, and the short shafts are in contact with the outer wall of the magnet 220. The surface area of ​​the square piece is smaller than the surface area of ​​the magnet 220. This size design ensures that the debris can enter the shallow groove 210, preventing the debris from being rubbed to other locations.

[0033] Specifically, the second magnet 270 is fixedly connected to the square piece, and the thickness of the second magnet 270 is smaller than the length of the short axis. This layout design ensures that debris can come between the first magnet 220 and the second magnet 270.

[0034] The working principle and use process of the utility model: when the device is put into actual use, it is installed inside the engine. Iron filings generated by the parts in the engine are adsorbed by magnet 1 220 and attached to the surface of magnet 1 220. Then, after being adsorbed by magnet 2 270, they gradually move between magnet 1 220 and magnet 2 270. This can prevent the debris from moving around, reduce the probability of wear of the device, and ensure its service life.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
