Description

Technical Field

[0001] This utility model belongs to the technical field of lower guard plate welding assembly, specifically, it relates to a lower guard plate welding assembly. Background Technology

[0002] The engine is located in the middle of the motorcycle frame, and a skid plate is installed at the bottom of the engine area. The skid plate is fixed to the bottom bar of the frame. This is especially important for off-road motorcycles. During riding, the bottom of the engine is prone to scraping against dirt slopes, and stones kicked up from the front wheel can also hit the engine. The skid plate plays a good role in protecting the engine. However, after the skid plate is fixed to the bottom bar, the bolts can easily loosen or even come off due to vibration. If one end of the skid plate comes off during riding, it can easily get caught in the rear wheel, causing a crash or causing damage to the engine's outer wall due to compression between the engine and the bottom surface. To prevent the skid plate from coming off, a welding assembly for the skid plate is provided. Utility Model Content

[0003] In view of this, the technical problem to be solved by this utility model is to provide a lower guard plate welding assembly, which solves the problem that the lower guard plate detachment in the prior art can easily cause the vehicle to crash or the engine to be damaged.

[0004] To solve the above-mentioned technical problems, this utility model discloses a lower guard plate welding assembly, including: a motorcycle frame and a lower guard plate; the motorcycle frame has a bottom bar arranged symmetrically on the left and right, each bottom bar is provided with two fixing parts, the fixing parts have symmetrically arranged protrusions and fixing plates, multiple fixing rings are welded to the inner surface of the lower guard plate, the fixing rings are provided with welding seats, the fixing rings are divided into a first leg and a second leg, the end of the first leg is provided with a through hole, the two ends of the through hole are respectively provided with a nut and a plug-in part, the end of the second leg is provided with a through hole, one end of the through hole is provided with a plug-in part, the plug-in parts on the first leg and the second leg are engaged with the slots on both sides of the fixing plate, and bolts are sequentially passed through the second leg, the fixing plate, the first leg and the nut.

[0005] Furthermore, the first and second legs are provided with limiting holes, which cooperate with the protrusions.

[0006] Furthermore, the aforementioned plug-in portion has a plurality of plug-in posts arranged in a ring array.

[0007] Furthermore, the aforementioned plug-in portion has multiple plug-in plates arranged in a ring array.

[0008] Furthermore, the cross-section of the aforementioned slot is L-shaped.

[0009] Compared with the prior art, this application can achieve the following technical effects:

[0010] This utility model features a protruding post and a fixing plate on the base bar. The protruding post engages with the limiting hole on the support leg, and the slot on the fixing plate engages with the insertion part on the support leg. The insertion part is pressed into the slot by the engagement of bolts and nuts, causing the insertion part to deform and yield to the internal shape of the slot. This ensures that the support leg and the fixing plate are securely engaged, preventing the bolts and nuts from loosening and reducing the risk of the lower guard plate and base bar detaching.

[0011] Of course, any product implementing this application does not necessarily need to achieve all of the technical effects described above at the same time. Attached Figure Description
