[0001] The utility model relates to the technical field of carburetors, in particular to a snap-on carburetors. Background Art

[0002] With the continuous progress of modern sports machinery, general gasoline engines have been widely developed. As a precise core component in gasoline engines and gasoline generators, carburetors use the kinetic energy of the inhaled air flow to achieve the atomization of gasoline. Carburetors can automatically match the corresponding oil and gas concentration according to the different working state requirements of the engine and output the corresponding amount of mixed gas. In the process of starting the vehicle to high-speed driving, the throttle cable drives the rotary valve to rotate, and then gradually achieves the effect of high-speed operation of the carburetors. The carburetors in the prior art generally include an upper cover and a lower cover, and the upper cover and the lower cover are locked by screws, generally requiring at least three screws, resulting in high production costs and low efficiency. Therefore, there is a need for a carburetors housing that can reduce costs and improve efficiency. Utility Model Content

[0022] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0023] Please refer to Figures 1 to 3 As shown, a buckle 2 type carburetor of the utility model comprises a carburetor body 1 and a buckle 2;

[0024] The carburetor body 1 comprises an upper cover 11, a lower cover 12 and a sealing ring 13; the sealing ring 13 is elastic and is located between the upper cover 11 and the lower cover 12;

[0025] Blind holes are respectively provided on the side walls of both sides of the upper cover 11; a limiting rib 121 is provided on a surface of the lower cover 12 away from the upper cover 11, and an upwardly protruding limiting portion 122 is provided at the end of the limiting rib 121, and a transition portion protruding upward and having a curve is provided on the limiting rib 121 close to the limiting portion 122;

[0026] The buckle 2 is U-shaped, and includes a middle part 21, connecting parts 22 on both sides, and bent parts 23 bent inward at both ends. The middle part 21 is connected to the bent parts 23 through the connecting parts 22 respectively; the buckle 2 is rotatably connected to the upper cover 11 through the bending parts 23 and the blind holes; the upper cover 11, the sealing ring 13, and the lower cover 12 are rotated in sequence and the middle part 21 of the buckle 2 is located between the limiting part 122 and the transition part 123.

[0027] From the above description, it can be known that by cooperating with the setting of the buckle 2 through the upper cover 11, the lower cover 12 and the sealing ring 13, the sealing ring 13 is compressed and deformed by squeezing the upper cover 11 and the lower cover 12 during assembly, so that the sealing ring 13 becomes thinner. At this time, after rotating the middle part 21 of the buckle 2 to be located between the limiting part 122 and the transition part 123, the upper cover 11 and the lower cover 12 are loosened to restore the sealing ring 13 to its original state, and the upper cover 11 and the lower cover 12 are fixed by the tension and friction force of the buckle 2. The structure is simpler and the fixing is more convenient. The buckle 2 can be fixed after being engaged through the transition part 123 and the limiting part 122.

[0028] Furthermore, the height of the limiting portion 122 is greater than or equal to the cross-sectional thickness of the buckle 2 .

[0029] From the above description, it can be seen that by the height of the limiting portion 122 being greater than or equal to the cross-sectional thickness of the buckle 2, the buckle 2 can be prevented from going over the limiting portion 122. At the same time, the limiting portion 122 can also protect the buckle 2 and reduce the probability of being hit.

[0030] Furthermore, the bending portion 23 is bent toward the middle portion 21 .

[0031] It can be seen from the above description that by bending the bent portion 23 toward the middle portion 21 of the buckle 2 , it is possible to avoid the bent portion 23 from being disengaged from the blind hole.

[0032] Furthermore, the connection portion 22 is bent toward another connection portion 22 .

[0033] Furthermore, a protruding force-bearing portion 124 is disposed at the bottom of the lower cover 12 , and a special-shaped portion 24 cooperating with the force-bearing portion 124 is disposed on the middle portion 21 .

[0034] It can be seen from the above description that the force-bearing portion 124 can be used to facilitate force bearing during installation, and the special-shaped portion 24 can cooperate with the force-bearing portion 124 to prevent interference.

[0035] Furthermore, the height of the force-bearing portion 124 is greater than or equal to the cross-sectional thickness of the buckle 2 .

[0036] It can be seen from the above description that by making the height of the force-bearing portion 124 greater than or equal to the thickness of the cross-section of the buckle 2 , the buckle 2 can be protected and the probability of being hit can be reduced.

[0037] Furthermore, the lower cover 12 is made of transparent material.

[0038] It can be seen from the above description that the transparent lower cover 12 makes it easier to observe the oil in the lower cover 12 .

[0039] Furthermore, there are two limiting ribs 121 .

[0040] Furthermore, the edges of the limiting ribs 121 are rounded.

[0041] It can be seen from the above description that the rounded edges of the limiting ribs 121 can prevent the installer's fingers from being scratched during installation.
