Description

Technical Field

[0001] The utility model relates to the technical field of superchargers, and in particular to an engine supercharger with high wear resistance. Background Art

[0002] Supercharging is a technology that pre-compresses the air before it is supplied to the cylinder to increase the air density and the intake volume. There are three types of superchargers: exhaust gas turbochargers, mechanical turbochargers and electrically assisted turbochargers. By compressing the air through the supercharger, the engine's intake density is increased, which can increase the engine's specific power. At the same time, since the engine's mixed combustion regulation is improved, the combustion efficiency is improved, so it can also save fuel and reduce emissions.

[0003] Due to its advantages, superchargers are widely used in engines. For example, an engine supercharger with high wear resistance can effectively improve the wear resistance of the engine supercharger by adding a rubber gasket to the exhaust port. However, there are still some shortcomings in actual use. Since the supercharger is mostly fixed by matching mounting holes and bolts, the bolts will become loose over a long period of use, which will affect the fixing effect of the supercharger and thus affect the normal operation of the supercharger. Therefore, improvements are needed. Utility Model Content

[0033] like Figures 1 to 6 As shown, the utility model provides an engine supercharger with high wear resistance, comprising:

[0034] A supercharger body 1, a mounting plate 2 is fixedly mounted on the front end of the supercharger body 1, and mounting holes 3 are respectively opened at the four corners of the mounting plate 2;

[0035] A fixing mechanism 4, which is arranged on the rear side of the mounting plate 2;

[0036] A locking mechanism 5, which is arranged outside the supercharger body 1;

There are two circular plates 405, and a first spring 406 is fixedly installed between the two circular plates 405. Hemispherical blocks 407 are fixedly installed on the opposite backs of the two circular plates 405, and the other end of the hemispherical block 407 penetrates the vertical plate 401 and extends to the outside of the vertical plate 401. The top of the outer surface of the hemispherical block 407 is movably connected to the bottom end of the movable plate 403, and the movable plate 403 will drive the fixed block 404 to move.

[0038] When the movable plate 403 moves downward along the outer surface of the vertical plate 401 with the fixed block 404, the bottom end of the movable plate 403 will squeeze the outer surface of the hemispherical block 407, so that the hemispherical block 407 and the two circular plates 405 move toward each other along the inner surface of the top of the vertical plate 401 and compress the first spring 406, thereby causing the hemispherical block 407 to completely retract into the interior of the vertical plate 401. When the fixed block 404 is aligned with the bolt on the mounting hole 3, the bolt can be locked to prevent the bolt from loosening, thereby reducing the fixing effect of the engine supercharger and affecting the normal operation of the engine supercharger.

[0039] Wherein, the locking mechanism 5 includes:

[0040] A square plate 501, the number of the square plates 501 is two, the two square plates 501 are movably sleeved on the left and right sides of the bottom end of the vertical plate 401, and a second spring 502 is fixedly installed between the two square plates 501;

The opposite surfaces of the two stoppers 503 are fixedly connected to the opposite back surfaces of the two square plates 501 , respectively.

[0042] When the movable plate 403 passes through the stopper 503, the stopper 503 will be squeezed, so that the two stoppers 503 respectively carry the two square plates 501 to move toward each other and compress the second spring 502. Under the restoring action of the second spring 502, the stopper 503 will return to its original position after the movable plate 403 passes, thereby locking the position of the movable plate 403.

[0045] Among them, a circular ring 8 is movably sleeved on the top of the outer surface of the circular block 6, the bottom end of the circular ring 8 is fixedly connected to the top end of the movable plate 403, the top end of the circular ring 8 is movably connected to the bottom end of the first handle 7, and a positioning hole 9 is opened inside the circular ring 8.

[0046] The positioning holes 9 are evenly distributed on the top of the circular ring 8 . The existence of the circular ring 8 and the positioning holes 9 will play a role in supporting and positioning the first handle 7 .

[0047] The positioning hole 9 is internally movably connected to a positioning rod 10, the top end of the positioning rod 10 passes through the first handle 7 and extends to the inside of the first handle 7 and is fixedly installed with a slide plate 11, the outer surface of the slide plate 11 is movably connected to the inner surface of the first handle 7.

[0048] When the slide plate 11 moves, the positioning rod 10 will be driven to move together, so that the positioning rod 10 and the positioning hole 9 are separated, and the positioning of the first handle 7 by the positioning rod 10 is released.

[0049] Among them, a long rod 12 is fixedly installed in the middle of the top of the skateboard 11, the top of the long rod 12 passes through the first handle 7 and extends to the outside of the first handle 7 and is fixedly installed with a second handle 13, and the bottom end of the second handle 13 is movably connected to the top of the first handle 7.

[0050] When the second handle 13 is pulled, the long rod 12 will move along the inner surface of the first handle 7 with the slide plate 11 .

[0054] The smooth design of the inner surface of the top of the vertical plate 401 and the outer surfaces of the two circular plates 405 ensures that the two circular plates 405 will not get stuck when moving along the inner surface of the top of the vertical plate 401.

[0055] There are four fixing blocks 404 , which are respectively located directly above the mounting holes 3 , and the bottom ends of the four fixing blocks 404 are each provided with a hexagonal groove.

[0057] The top ends of the two stoppers 503 on one side outside the vertical plate 401 are both smooth inclined surfaces.

[0058] The smooth inclined surfaces on the top of the two stoppers 503 will not hinder the movement of the movable plate 403 .

[0059] The working principle and use process of this utility model:

[0060] First, after the operator fixes the engine supercharger with bolts and the mounting holes 3, the operator pushes the movable plate 403 downward, so that the movable plate 403 moves downward along the outer surface of the vertical plate 401 with the fixed block 404. At this time, the movable plate 403 will squeeze the hemispherical block 407, so that the two hemispherical blocks 407 respectively move toward each other along the inner surface of the top of the vertical plate 401 with the two circular plates 405 and compress the first spring 406 until the hemispherical block 407 is completely retracted into the interior of the vertical plate 401, thereby releasing the hemispherical block 407 from blocking the movable plate 403. Then the operator continues to push the movable plate 403. When the movable plate 403 is When the plate 403 and the stopper 503 come into contact, since the top end of the stopper 503 is an inclined surface, the stopper 503 will be squeezed and move the two square plates 501 along the inner surface of the bottom end of the vertical plate 401 toward each other and compress the second spring 502. When the fixed block 404 completely overlaps with the bolt, the movable plate 403 and the stopper 503 are separated. At this time, under the restoring action of the second spring 502, the stopper 503 will be restored to its original position, so that the bottom end of the stopper 503 and the top end of the movable plate 403 are fitted together, and then the movable plate 403 is locked in position, thereby preventing the bolt from loosening and affecting its fixing effect.

[0061] Before the fixing block 404 and the bolt overlap, the operator pulls the second handle 13 according to the rotational position of the bolt, so that the second handle 13 moves upward along the inner surface of the first handle 7 with the slide plate 11 through the long rod 12 and compresses the connecting spring 14, so that the positioning rod 10 fixedly connected to the slide plate 11 moves along and separates from the positioning hole 9, thereby releasing the locking of the first handle 7 position by the positioning rod 10, and then the operator rotates the first handle 7, so that the first handle 7 rotates with the fixing block 404 through the round block 6 until the rotational position of the fixing block 404 and the bolt are consistent, and then the operator releases the second handle 13. At this time, under the recovery action of the connecting spring 14, the slide plate 11 will restore to its original position with the positioning rod 10, thereby embedding into the ring 8, and then locking the position of the first handle 7 and the fixing block 404, thereby ensuring that the fixing block 404 can overlap with the bolt smoothly.

[0062] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
