Description

Technical Field

[0001] This utility model relates to the technical field of engine component mounting brackets, and more specifically to an engine bracket for fixing an air pump. Background Technology

[0002] As the market share of non-road diesel engines grows and the market audience expands, customer demands are also increasing. Often, customers request additional components for their non-road diesel engines, such as air pumps. However, due to limited space at the engine mounting location, there isn't enough room to install the air pump. Therefore, some have suggested mounting the air pump on the outer wall of the diesel engine, requiring the design of a corresponding bracket. When designing this bracket, it's necessary to consider that the outer wall of the diesel engine is not a single flat surface but consists of multiple structural surfaces with varying elevations. Furthermore, the elevation differences between these surfaces vary depending on the type of engine. Therefore, a mounting bracket that fits the structural surfaces of the mounting holes and offers universal compatibility is needed. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing an engine bracket for fixing an air pump. The bracket has multiple support points that abut against the outer wall surface of the engine. Based on the support points, the connection strength between the bracket and the engine can be improved, thereby ensuring that the air pump is firmly installed on the engine.

[0004] An engine bracket for fixing an air pump includes a horizontally upright engine mounting plate, a horizontal air pump mounting plate fixedly connected to the lower part of the engine mounting plate, and four sets of rectangular mounting holes formed on the left side of the air pump mounting plate, including two sets of diagonally distributed air pump mounting holes and two sets of diagonally distributed locating pin holes; several longitudinally upright upper reinforcing ribs are fixedly connected between the right side of the air pump mounting plate and the engine mounting plate.

[0021] Example: See Figures 1 to 4 As shown, an engine bracket for fixing an air pump includes a horizontally upright engine mounting plate 1. A horizontal air pump mounting plate 2 is fixedly connected to the lower part of the engine mounting plate 1. The left side of the air pump mounting plate 2 has four sets of rectangular mounting holes distributed at the four corners. The four sets of mounting holes include two sets of diagonally distributed air pump mounting holes 21 and two sets of diagonally distributed locating pin holes 22. Several longitudinally upright upper reinforcing ribs 3 are fixedly connected between the right side of the air pump mounting plate 2 and the engine mounting plate 1.

[0022] The left side of the engine mounting plate 1 is formed with a plurality of engine mounting holes 11. A circular convex ring seat 13 is formed on the front end face of the left end of the engine mounting hole 11. A longitudinal T-shaped stud 6 is inserted into the convex ring seat 13. The rear end of the stud 6 extends out of the engine mounting plate 1 and is screwed with an adjusting sleeve 8. A D-shaped limiting pin 7 is inserted into the convex ring seat 13. The limiting pin 7 is inserted into the head of the stud 6, and the lower end of the limiting pin 7 abuts against the air pump mounting plate 2.

[0023] Several T-shaped adjusting sleeves 5 are screwed between the upper reinforcing ribs 3 on the right side of the engine mounting plate 1. The center of the adjusting sleeve 5 is formed with a bolt through hole, and the front end face of the adjusting sleeve 5 is formed with a countersunk hole 51 that communicates with the bolt through hole. Several actuating grooves 52 are formed on the inner wall of the countersunk hole 51.

[0024] The diameter of the engine mounting hole 11 on the engine mounting plate 1 is equal to the diameter of the bolt through hole in the adjusting sleeve 5; both the engine mounting hole 11 and the bolt through hole in the adjusting sleeve 5 are used to insert bolts connected to the engine.

[0025] The rear end of the adjusting sleeve 5 extends out of the engine mounting plate 1 and is screwed with a thin nut 9, which presses against the rear end face of the engine mounting plate 1. After the adjustment of the adjusting sleeve 5 is completed, the nut 9 can be used to constrain the rotation of the adjusting sleeve 5, thereby preventing the adjusting sleeve 5 from rotating during the bolt rotation process.

[0026] The four sets of mounting holes on the air pump mounting plate 2 are all distributed on the front side of the convex ring seat 13 and the stud 6; the front end face of the stud 6 is flush with the front end face of the convex ring seat 13, so the convex ring seat 13 and the stud 6 will not cause interference to the installation of the air pump.

[0027] The lower left end of the engine mounting plate 1 is formed into a support plate 12 that extends downward and is in the shape of an isosceles trapezoid. A longitudinally upright lower reinforcing rib 4 is fixed to the support plate 12. The upper end of the lower reinforcing rib 4 is fixed to the lower end surface of the air pump mounting plate 2. The lower reinforcing rib 4 improves the strength of the support.

[0028] The length of the adjusting sleeve 8 on the stud 6 is greater than the length of the stud 6 extending out of the engine mounting plate 1. The outer walls on opposite sides of the adjusting sleeve 8 are formed with planar grooves, which facilitate the rotation adjustment of the adjusting sleeve 8.

[0029] A circular expansion hole 23 is formed on one side of the inner wall of the positioning pin hole 22 on the air pump mounting plate 2. The diameter of the positioning pin hole 22 is generally slightly smaller than the diameter of the positioning pin. By adding the expansion hole 23, the diameter of the positioning pin hole 22 can be expanded, so that the interference fit between the positioning pin and the positioning pin hole 22 can be achieved.

[0030] Figure 2 As shown, the engine mounting holes 11 on the left side of the engine mounting plate 1 are provided in three sets. Two sets of the three sets of engine mounting holes 11 are distributed vertically and located between the positioning pin holes 22, and the other set is close to the upper reinforcing rib plate 3.

[0031] Working principle: This structure is an engine bracket for fixing the air pump. The engine bracket is installed and connected to the outer wall of the engine by bolts. Before installation, the adjusting sleeve 5 and adjusting screw sleeve 8 can be rotated and adjusted to make the engine mounting plate 1 abut against the outermost outer wall of the engine. At the same time, the rear ends of the adjusting sleeve 5 and adjusting screw sleeve 8 abut against other structural surfaces of the engine outer wall, so that there are multiple support points between the engine mounting plate 1 and the engine outer wall. When the bolts are finally installed, the bracket can be firmly fixed to the engine. Finally, the air pump is installed and fixed on the air pump mounting plate 2 by the positioning pin and corresponding bolts.

[0032] Because the positions of the adjusting screw sleeve 8 and the adjusting sleeve 5 are adjustable, they can fit together with various structural surfaces of different depths, thus possessing versatility and being able to be installed on different types of engines.

[0033] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
