Description

Technical fields:

[0001] This utility model relates to the field of engine parts and equipment technology, and more specifically to a quick-installation engine protective cover. Background technology:

[0002] As my country's engine manufacturing technology continues to improve, various engine manufacturers are enhancing product quality, attracting customer attention, and meeting users' aesthetic and modern needs by improving appearance, upgrading electrification, and meeting intelligent requirements. The industrial design of engine protective covers is used to beautify the appearance of engines and product image.

[0003] For engine manufacturing, the installation of protective covers should reduce the labor intensity of workers and improve production efficiency. For maintenance, they should be adaptable to multiple disassembly and assembly, and solve the problems of difficult control of bolt torque and easy damage to the protective covers.

[0004] Existing engine guards are generally fixed with bolts. Bolt installation increases the labor intensity of workers and takes a long time to install and remove. At the same time, because the torque required to turn the bolts is not easy to control, the bolts are prone to being overtightened. This causes excessive pressure on the corresponding installation position of the rotating part of the bolt against the top plate of the engine guard, which can deform or even break the bolt. Utility Model Content:

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a quick-installation engine cover. It adopts a plug-in structure to realize installation and disassembly, which is convenient for installation and disassembly. The engine cover body is not easily damaged or deformed and has good performance.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A quick-installation engine cover includes an engine cover body, which is a horizontally extending cover plate. The bottom edge of the cover body has multiple downwardly extending cylindrical sleeve portions. A rubber elastic post is inserted into each cylindrical sleeve portion. The lower part of the rubber elastic post extends out of the bottom end of the cylindrical sleeve portion. An upwardly extending locking hole is formed in the middle of the bottom end face of the rubber elastic post.

[0008] An inner annular protrusion is formed on the inner side wall of the bottom end of the cylindrical sleeve. The upper part of the rubber elastic column is inserted into the cylindrical sleeve, and the inner annular protrusion is embedded in the annular groove formed on the outer side wall of the middle part of the rubber elastic column.

[0009] The bottom end face of the rubber elastic column is formed with a frustum-shaped concave hole with a larger inner diameter at the bottom and a smaller inner diameter at the top. The top surface of the frustum-shaped concave hole is formed with a locking hole that extends vertically upward.

[0010] The top rod of the upper fixing bolt is inserted into the locking hole. The top end of the top rod is formed with a spherical part. The outer diameter of the spherical part is larger than the inner diameter of the locking hole. The outer side wall of the spherical part is pressed against the upper inner side wall of the locking hole, and the spherical part is locked in the locking hole.

[0011] The middle outer wall of the upper fixing bolt rod has an annular protrusion, which is inserted into a frustum-shaped concave hole. The lower outer wall of the rod has an external thread.

[0012] The lower part of the upper fixing bolt is screwed into the screw hole at the top of the lower connecting bolt.

[0013] The outstanding effect of this utility model is:

[0014] It adopts a plug-in structure for installation and disassembly, which makes installation and disassembly convenient, the engine cover body is not easily damaged or deformed, and the performance is good.

[0015] It uses a snap-fit ​​method to fix the rubber elastic post, making it difficult for it to detach from the engine cover body and ensuring a firm connection. Attached image description:

[0018] Figure 3 This is a partial structural schematic diagram of the connecting bolt of this utility model. Detailed implementation method:

[0019] For example, see below. Figures 1 to 3 As shown, a quick-install engine cover includes an engine cover body 10. The engine cover body 10 is a horizontally extending nylon cover plate. One side of its top surface is formed with multiple upwardly extending waist-shaped protrusions, and the middle of its top surface is formed with a horizontally extending protruding strip. The other side of its top surface is formed with multiple protrusions. Corresponding upwardly extending recesses of the shape are formed on the bottom surface of the engine cover body 10 corresponding to the protrusions, protruding strips, and waist-shaped protrusions. This structure not only improves the aesthetic appearance of the engine cover body 10, but also strengthens the overall strength of the top plate of the engine cover body 10.

[0020] The bottom edge of the engine cover body 10 is formed with a plurality of downwardly extending cylindrical sleeve portions 11. A rubber elastic post 20 is inserted in the cylindrical sleeve portion 11. The rubber elastic post 20 is a nitrile rubber elastic post. The lower part of the rubber elastic post 20 extends out of the bottom end of the cylindrical sleeve portion 11. An upwardly extending locking hole 21 is formed in the middle of the bottom end face of the rubber elastic post 20.

[0021] Furthermore, an inner annular protrusion 12 is formed on the inner sidewall of the bottom end of the cylindrical sleeve portion 11, the upper part of the rubber elastic column 20 is inserted into the cylindrical sleeve portion 11, the inner annular protrusion 12 is embedded in the annular groove 23 formed on the outer sidewall of the middle part of the rubber elastic column 20, and the lower part of the rubber elastic column 20 is located below the cylindrical sleeve portion 11.

[0022] The bottom end face of the rubber elastic column 20 is formed with a frustum-shaped concave hole 22 with a larger inner diameter at the bottom and a smaller inner diameter at the top. The top surface of the frustum-shaped concave hole 22 is formed with a vertically extending locking hole 21.

[0023] The top rod 31 of the upper fixing bolt 30 is inserted into the locking hole 21. The top end of the top rod 31 is formed with a spherical part 32. The outer diameter of the spherical part 32 is larger than the inner diameter of the locking hole 21. The outer side wall of the spherical part 32 is pressed against the upper inner side wall of the locking hole 21, and the spherical part 32 is locked in the locking hole 21.

[0024] The upper fixing bolt 30 has an annular protrusion 33 formed on the outer wall of the middle part of the rod body. The annular protrusion 33 is inserted into the frustum-shaped concave hole 22. The lower part of the rod body is located below the rubber elastic column 20, and its outer wall is formed with external threads.

[0025] The lower part of the upper fixing bolt 30 is screwed into the screw hole at the top of the lower connecting bolt 40, and the top surface of the lower connecting bolt 40 presses against the bottom surface of the annular protrusion 33.

[0026] The bottom surface of the engine cover body 10, where the cylindrical sleeve portion 11 is located, is formed with a threaded post 13. An elastic extension post 24 formed in the center of the top surface of the rubber elastic post 20 is inserted into the upper part of the cylindrical sleeve portion 11. The threaded post 13 is engaged in the connecting hole formed in the center of the top surface of the elastic extension post 24. During installation, the upper part of the rubber elastic post 20 is engaged in the cylindrical sleeve portion 11, so that the bottom of the threaded post 13 is engaged in the corresponding connecting hole (achieved through the elastic deformation of the inner wall of the connecting hole of the elastic extension post 24). Its external thread increases the contact area with the inner wall of the connecting hole, improving the engagement strength. Simultaneously, the inner annular protrusion 12 is embedded in the annular groove 23 formed on the outer wall of the middle part of the rubber elastic post 20, further improving the fixing effect of the rubber elastic post 20, ensuring that the rubber elastic post 20 will not be pulled out of the cylindrical sleeve portion 11 when the engine cover body 10 is subsequently lifted.

[0027] The top surface of the spherical part 32 is a horizontal surface, which presses against the top surface of the locking hole 21.

[0028] In this embodiment, the lower connecting bolt 40 is installed on the engine mounting housing. The lower part of the upper fixing bolt 30 is screwed into the screw hole at the top of the lower connecting bolt 40, so that the bottom end face of the annular protrusion 33 presses against the top end face of the lower connecting bolt 40, thereby achieving fixation.

[0029] Then, install the engine cover body 10 by aligning the top rod 31 of the upper fixing bolt 30 with the bottom end of the cylindrical sleeve part 11 of the engine cover body 10, and pressing down on the engine cover body 10 so that the top rod 31 is inserted into the locking hole 21 and the spherical part 32 is locked in the locking hole 21, thus completing the installation. The installation is convenient and only requires pressing down to install.

[0030] During disassembly, the engine cover body 10 needs to be lifted up so that the top rod 31 and the ball part 32 can be disengaged from the locking hole 21. The disassembly is convenient and efficient. Since no bolts or other parts are used to fix the engine cover body 10, there are no pressing parts on the top plate of the engine cover body 10, making it less prone to deformation and damage, thus ensuring its service life.

[0031] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
