The engine flywheel housing is fixedly mounted on the outside of the connecting plate through a fixed seat sleeve, and the elastic force of the spring pushes the sliding block to move. During the movement of the sliding block, the clamping rod is pushed through the inside of the through opening and inserted into the inside of the clamping groove, so that the dustproof housing body can be fixed on the surface of the flywheel housing body for protection. The structure is simple and the operation is fast, and it replaces the traditional bolt fixing method to avoid looseness between the fixed connection between the flywheel housing body and the dustproof housing body.

[0004] This patent has a simple structure and is quick to operate. It replaces the traditional bolt fixing method to avoid loosening between the fixed connection between the flywheel housing body and the dustproof housing body. However, the existing dustproof net is relatively cumbersome to install and disassemble, and cannot achieve the effect of quick disassembly and assembly. Therefore, we propose a new type of engine flywheel housing. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0027] Embodiment 1, as Figure 1-Figure 7 As shown, the utility model provides an engine flywheel housing, including a flywheel housing body 1, a housing 2 is connected to one side of the flywheel housing body 1, a dustproof component 3 is connected to one side of the housing 2, the dustproof component 3 includes a fan 301 and a dustproof frame 302, a dustproof frame 302 is connected to one side of the fan 301, a dustproof net 303 is arranged inside the dustproof frame 302, plug holes 304 are opened on both sides of the outer surface of the dustproof net 303, and a fixing block 305 is connected to both sides of the outer surface of the dustproof frame 302, a first spring 306 is arranged inside the fixing block 305, a push rod 307 is inserted inside the first spring 306, one end of the push rod 307 is connected to a pull block 308, and the other end of the push rod 307 is connected to a push plate 30 9. One side of the push plate 309 is connected with an insert block 310. Notches 311 are provided at the inner bottoms of both sides of the dustproof frame 302. A second spring 312 is provided inside the notch 311. The outer surface of the dustproof net 303 fits with the inner surface wall of the dustproof frame 302. The dustproof net 303 and the dustproof frame 302 are in sliding connection. The push plate 309 forms an elastic structure with the fixed block 305 through the first spring 306. The position and size of the insert block 310 match the position and size of the jack 304. An oblique opening is provided on one side of the insert block 310. The dustproof net 303 forms an elastic structure with the second spring 312 through the notch 311. The top surface of the second spring 312 fits with the bottom surface of the dustproof net 303.

[0028] The effect achieved by the entire embodiment 1 is that when the fan 301 is turned on for a long time to dissipate heat, the surface of the dustproof net 303 will absorb more dust. In order to avoid clogging, the dustproof net 303 needs to be replaced regularly. When the dustproof net 303 needs to be replaced, the two sets of pull blocks 308 can be grasped and pulled to both sides at the same time, so that the pull blocks 308 can drive the push plates 309 to squeeze the first springs 306 through the push rods 307, and the plug blocks 310 can be pulled out of the plug holes 304. Then the second springs 312 will push the dustproof net 303 upwards through their own elastic force, so that the dustproof net 303 can be pushed out of the dustproof frame 302, thereby completing the quick disassembly of the dustproof net 303. When the dustproof net 303 needs to be installed, the dustproof net 303 can be directly pushed into the dustproof frame 302. When the bottom sides of the dust net 303 contact the plug block 310, continue to push downward so that the bottom of the dust net 303 squeezes the plug block 310. At this time, the plug block 310 will shrink toward the fixing block 305 after being squeezed, and push the push rod 307 to compress the first spring 306. When the dust net 303 is fully inserted into the dust frame 302, the dust net 303 will also push the second spring 312 into the slot 311. At this time, the dust frame 302 will push the push plate 309 through its own elastic force, driving the plug block 310 to be inserted into the socket 304, completing the fixation of the dust net 303. In this way, the dust net 303 is quickly disassembled and assembled, avoiding the cumbersome problem of the existing dust net 303 during disassembly and assembly, and improving the convenience of disassembling and assembling the dust net 303.

[0029] Embodiment 2, as Figure 1 , Figure 2 and Figure 8 As shown, a disassembly assembly 4 is arranged between the flywheel housing body 1 and the outer shell 2, and the disassembly assembly 4 includes a threaded hole 401 and a hole 402. A threaded hole 401 is opened on the surface of the flywheel housing body 1 on one side close to the outer shell 2, and a hole 402 is opened on the side of the outer shell 2 close to the flywheel housing body 1. A threaded rod 403 is inserted into the inside of the hole 402, and the threaded rod 403 passes through the hole 402 to form a threaded connection with the threaded hole 401.

[0030] The effect achieved by the entire embodiment 2 is that when part of the outer shell 2 is damaged and needs to be replaced, the threaded rods 403 can be rotated in the opposite direction, and all the threaded rods 403 can be taken out from the threaded holes 401, and the outer shell 2 can be replaced separately. When installing the new outer shell 2, it is necessary to align the hole 402 with the threaded hole 401, and the threaded rod 403 is passed through the hole 402 and then threadedly connected and fixed with the threaded hole 401. This avoids the problem that most of the existing flywheel housing body 1 is integrated and needs to be completely replaced when damaged, thereby avoiding unnecessary waste of resources.

[0031] Working principle: when the dustproof net 303 needs to be replaced, the pull block 308 is directly pulled to both sides, and then the second spring 312 will push the dustproof net 303 out of the dustproof frame 302; when the dustproof net 303 needs to be installed, the dustproof net 303 is directly pushed into the dustproof frame 302, and the plug block 310 will automatically be inserted into the plug hole 304, thereby completing the quick disassembly and assembly of the dustproof net 303, avoiding the cumbersome problem of the existing dustproof net 303 during disassembly and assembly, and improving the convenience of disassembly and assembly of the dustproof net 303; when part of the outer shell 2 is damaged and needs to be replaced, the threaded rod 403 can be removed and the outer shell 2 can be replaced separately, avoiding the problem that most of the existing flywheel housing body 1 is integrated and needs to be completely replaced when damaged, thereby avoiding unnecessary waste of resources.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in other forms. Any technician familiar with the profession may use the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
