[0023] The technical solution of this patent will be further described in detail below in combination with the specific implementation mode

[0024] Please refer to Figures 1-4 , an engine hanger connection structure, including a fixing mechanism 1. The fixing mechanism 1 includes an L-shaped connecting plate 101. Two groups of L-shaped connecting plates 101 are symmetrically arranged. Limiting perforations 107 are opened inside both groups of L-shaped connecting plates 101. Connecting studs 102 penetrate through both groups of limiting perforations 107. The limiting perforations 107 are provided for the connecting studs 102 to penetrate through. Reinforcing plates 108 are symmetrically arranged on both sides of both groups of connecting nuts 103. The two sides of the reinforcing plates 108 are respectively fixedly connected to the two groups of L-shaped connecting plates 101. The setting of the reinforcing plates 108 can further improve the strength of the L-shaped connecting plates 101. Connecting nuts 103 are fixedly connected to the tops of both groups of connecting studs 102. The setting of the connecting nuts 103 can play a role in limiting the L-shaped connecting plates 101 after the connecting studs 102 penetrate through the limiting perforations 107 and are screwed into the hanger mounting screw holes on the engine housing

[0025] A limiting washer 104 is sleeved outside two groups of connecting studs 102. The limiting washer 104 is arranged at the bottom of the connecting nut 103. The arrangement of the limiting washer 104 can separate the connecting nut 103 from the L-shaped connecting plate 101, so as to reduce the probability of the connecting nut 103 wearing the surface of the connecting nut 103. A plurality of limiting bumps 105 are fixedly connected in an annular array at the bottom of the two groups of limiting washers 104. Limiting grooves 106 adapted to the limiting bumps 105 are formed in an annular array on the top walls of the two groups of L-shaped connecting plates 101. The arrangement of the limiting bumps 105 can limit the limiting washer 104 after being inserted into the inside of the limiting grooves 106, so as to ensure that the limiting washer 104 and the limiting through hole 107 can be coaxially arranged, so that the connecting studs 102 and the limiting washers 104 adapted to the lifting lug mounting screw holes on the engine housing can be selected according to requirements, and the probability of the L-shaped connecting plate 101 deviating can be reduced after the limiting washer 104 is limited.

[0026] The hanging mechanism 2 includes a suspension rod 201 that slidably penetrates through the inside of one side L-shaped connecting plate 101. The arrangement of the suspension rod 201 can provide a hanging position when lifting the engine. A through hole 205 adapted to the suspension rod 201 is formed in the inside of the other side L-shaped connecting plate 101. The suspension rod 201 penetrates through the through hole 205. The arrangement of the through hole 205 is used for the suspension rod 201 to penetrate through, so as to play a role in limiting the suspension rod 201. At the same time, after the suspension rod 201 is slid out of the inside of the through hole 205, it is convenient to bypass the suspension rope around the outside of the suspension rod 201, so that the placement of the suspension rope is more convenient. A limiting ring 202 is fixedly connected to the outside of the suspension rod 201. The limiting ring 202 abuts against the other side L-shaped connecting plate 101. The arrangement of the limiting ring 202 can play a role in limiting the suspension rod 201.

[0027] One end of the suspension rod 201 is fixedly connected with a connecting block 204. A spring 203 is fixedly connected between the connecting block 204 and one side L-shaped connecting plate 101. The spring 203 is sleeved outside the suspension rod 201. Specifically, the spring 203 is in a stretched state, so that the elastic action of the spring 203 can be used to pull the connecting block 204 and the suspension rod 201 to move towards one side of the through hole 205, so as to reduce the probability of the suspension rod 201 disengaging from the inside of the through hole 205. Through grooves 206 communicating with each other are symmetrically formed on the inner wall of the through hole 205. Limiting blocks 207 adapted to the through grooves 206 are symmetrically fixedly connected to the outer wall of the suspension rod 201. The through grooves 206 are used for the limiting blocks 207 to penetrate through, and the limiting blocks 207 can play a role in limiting the suspension rod 201 after rotating to be misaligned with the through grooves 206, so as to further limit the probability of the suspension rod 201 disengaging from the inside of the through hole 205.

[0028] During use, two connecting studs 102 and limit washers 104 that are adapted to the size of the lifting lug mounting screw holes on the engine housing can be selected. Then, the two groups of limit washers 104 are respectively placed on the tops of the two L-shaped connecting plates 101 on both sides, and the limit bumps 105 are inserted into the corresponding limit grooves 106. Next, the two groups of connecting studs 102 respectively penetrate through the two groups of limit washers 104 and the two groups of limit perforations 107, and are screwed into the two lifting mounting screw holes on the engine housing, thereby realizing the installation of the entire engine lifting lug. Since the suspension rod 201 is slidably connected to one side of the L-shaped connecting plate 101, the distance between the two L-shaped connecting plates 101 can be freely adjusted, so as to adapt to the lifting lug mounting screw holes with different distances on the engine cover, and thus effectively improve the applicability of the entire engine lifting lug.
