Description

Technical Field

[0001] This utility model relates to the field of carburetor needle adjustment technology, and in particular to a carburetor with an easily adjustable needle. Background Technology

[0002] A carburetor is a mechanical device that mixes gasoline and air in a certain proportion under the action of an engine. Fuel efficiency can be achieved by adjusting the needle valve. The end surface of the needle valve has multiple annular grooves, and shims are engaged in these grooves. Therefore, when adjusting, you can use pliers to grasp the shims of the needle valve and move them to different positions in the annular grooves. Raising the needle valve will make the mixture richer, while lowering it will make the mixture leaner. However, it is difficult to move the shims directly with pliers. The shims are restricted by the grooves, and it takes a lot of force to move the shims out of the grooves and move them to a new position. This is slow and inefficient.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0027] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0028] A carburetor with an easily adjustable needle includes a housing 1. Inside the housing 1, a needle body 2 is disposed. Eight ends 3 are sequentially disposed at one end of the needle body 2. A connection hole 11 is provided on one side of each end 3. A sleeve block 4 is fixedly connected to the side of each end 3 away from the connection hole 11. A gasket 5 is fitted on the surface of one of the sleeve blocks 4. A connector 10 adapted to the connection hole 11 is fixedly connected to one side of the sleeve block 4. A slot 6 is provided on the top of the sleeve block 4. A snap-fit ​​assembly is provided on the top of the inner side of the gasket 5. The snap-fit ​​assembly is adapted to the corresponding slot 6.

[0029] The specific usage process is as follows: It should be noted that the eight ends 3 are identical and can be connected end to end. The end of the oil needle body 2 facing the end 3 also has a mounting hole identical to the connecting hole 11 on the end 3. First, remove the end cap 17 from the outer shell 1. Then, remove the spring 16, and then remove the collar 12 from the outer shell 1. Next, remove the retaining ring 15 from the collar 12. Then, push the end of the oil needle body 2 against the outside of the collar 12, that is, push the end of the oil needle body 2 inside the collar 12 out of the collar 12. The gasket 5 will then move out of the adapter groove 14 along with the oil needle body 2. Then, remove the oil needle body 2. After that, the position of the gasket 5 can be adjusted. Adjustment is done by directly attaching the end cap 17 to the outer shell 1. Loosen and remove the end 3 with gasket 5 by rotating it. It should be noted that the other ends 3 connected to this end 3 will also be removed along with it. After this end 3 is removed, gasket 5 will fall off. Set aside the fallen gasket 5 for later use. Then, loosen and remove the end 3 in the designated position from the entire oil needle body 2. Similarly, the other ends 3 connected to this end 3 will also be removed. Then, pick up the removed gasket 5 and attach it to the end 3 removed from the corresponding position. Specifically, attach the gasket 5 to the sleeve block 4 on this end 3. During installation, align the retaining block 7 and the abutment block 8 inside the gasket 5 with the retaining groove 6 on the sleeve block 4 and insert them. During this process, the abutment block 8 will be pressed into the retaining block 7 by the pressure from the inner wall of the retaining groove 6. Compress spring 9 until the locking block 7 and the abutment block 8 are fully engaged deep into the inner cavity of the slot 6. Then, rotate the washer 5 to lock the locking block 7 into the slot 6. Simultaneously, the position of the locking block 7 changes, and the abutment block 8 is no longer squeezed by the inner wall of the slot 6. Under the action of spring 9, the abutment block 8 is ejected from the locking block 7 and abuts against the inner wall of the slot 6. This effectively limits the locking block 7, preventing the washer 5 from moving freely on the sleeve 4, and thus preventing the washer 5 from moving freely within the groove on the oil needle body 2, providing convenience for the user. Next, align the connector 10 on the sleeve 4 with the corresponding connecting hole 11 on the end 3, and then twist the end 3 with the washer 5 until it is fully installed. After inserting the connecting hole 11 into the corresponding end 3, reassemble the remaining disassembled ends 3 in the same manner. This completes the disassembly and assembly of the oil needle body 2, and also completes the position adjustment of the gasket 5 and the adjustment of the oil needle body 2. The entire adjustment process is quick, convenient, easy to operate, and highly efficient. The groove on the oil needle is formed by two adjacent sleeve blocks 4 and a corresponding sleeve block 4. It is used to lock the gasket 5 in place, preventing the gasket 5 from moving freely on the oil needle, and also to adjust the extension length of the oil needle, thereby achieving the purpose of saving oil. The snap-fit ​​assembly consists of a snap-fit ​​block 7, a stop block 8, and a spring 9. The snap-fit ​​assembly is also compatible with the snap-fit ​​groove 6. Therefore, during installation, after snapping the snap-fit ​​assembly into the corresponding snap-fit ​​groove 6,Under the action of spring 9, the stop block 8 is ejected from the inner cavity of the locking block 7 and abuts against the inner wall of the locking groove 6. The locking block 7 can then be firmly locked in the locking groove 6, ensuring the firmness and stability of the gasket 5 after installation, and providing convenience for the user's work. The fixing block 13 is fixed in the inner cavity of the collar 12. After the oil needle body 2 is installed, the gasket 5 will be inserted into the adapter groove 14. Then, the retaining spring 15 is also fastened in the collar 12 and restricts the gasket 5, so that the gasket 5 and the oil needle body 2 will not move freely, ensuring the stability of the oil needle body 2 during operation and providing convenience for the user's work. One end of the second spring 16 extends into the collar. The end cap 17 is installed on the outer casing 1, thus compressing the second spring 16. The spring 16's own elasticity pushes the collar 12 firmly against the inner wall of the outer casing 1, ensuring the stability of the collar 12 and the needle valve body 2 after installation, and improving the stability of the needle valve body 2 during operation. Both mounting blocks 18 and 19 are used to install and fix the carburetor. The mounting directions of mounting blocks 18 and 19 are different, allowing the carburetor to be installed in multiple different positions, providing more flexibility and convenience for users.

[0030] Therefore, the oil needle structure is designed with multiple end blocks connected by threads at the tail end. When adjusting the oil needle, simply remove the end block corresponding to the shim, and the shim will fall off. Remove the end block that the shim is clipped to the set position and tighten it to fix the end block. This quickly completes the adjustment of the oil needle, improves the adjustment efficiency of the oil needle, and provides convenience for users' work.

[0031] The diameter of the sleeve 4 is smaller than the diameter of the end 3. The sleeve 4 is located between two adjacent ends 3, and the two adjacent ends 3 and the corresponding sleeve 4 form a groove that is compatible with the gasket 5.

[0032] Specifically, the end 3 and the sleeve 4 are designed such that the groove on the oil needle is formed by two adjacent sleeves 4 and the corresponding sleeve 4. It is used to snap the installation of the gasket 5 to prevent the gasket 5 from moving freely on the oil needle. It is also used to adjust the extension length of the oil needle, thereby achieving the purpose of saving oil.

[0033] The snap-fit ​​assembly includes a snap-fit ​​block 7 fixedly connected to the inner wall of the gasket 5. A stop block 8 is embedded and slidably installed on one side of the snap-fit ​​block 7. Both the snap-fit ​​block 7 and the stop block 8 are adapted to the corresponding snap-fit ​​slot 6. A spring 9 is fixedly connected to one side of the stop block 8. The end of the spring 9 away from the stop block 8 is fixedly connected to the inner wall of the snap-fit ​​block 7.

[0034] Specifically, the snap-fit ​​assembly consists of a snap-fit ​​block 7, a stop block 8, and a spring 9. The snap-fit ​​assembly is also compatible with the slot 6. Therefore, during installation, after the snap-fit ​​assembly is inserted into the corresponding slot 6, the spring 9 causes the stop block 8 to pop out of the inner cavity of the snap-fit ​​block 7 and abut against the inner wall of the slot 6. This allows the snap-fit ​​block 7 to be firmly secured within the slot 6, ensuring the stability and secureness of the gasket 5 after installation and providing convenience for the user.

[0035] A fixing block 13 is sleeved on the outside of the oil needle body 2. An adapter groove 14 that matches the gasket 5 is opened on one side of the fixing block 13. A collar 12 is provided on the outside of the fixing block 13. The collar 12 is slidably installed in the outer shell 1. A retaining spring 15 is provided on one side of the fixing block 13. The retaining spring 15 is fastened in the collar 12.

[0036] Specifically, the collar 12, fixing block 13, adapter groove 14, and retaining spring 15 are configured such that the fixing block 13 is fixed in the inner cavity of the collar 12. After the oil needle body 2 is installed, the gasket 5 will be inserted into the adapter groove 14, and then the retaining spring 15 will also be fastened in the collar 12 and restrict the gasket 5, so that the gasket 5 and the oil needle body 2 will not move freely, ensuring the stability of the oil needle body 2 during operation and providing convenience for the user's work.

[0037] The inner cavity of the outer shell 1 is provided with a second spring 16, one end of which extends into the collar 12. An end cap 17 is detachably installed on one side of the outer shell 1, and one end of the second spring 16 abuts against the end cap 17.

[0038] Specifically, regarding the arrangement of spring 16 and end cap 17, one end of spring 16 extends into collar 12. Therefore, after end cap 17 is installed on housing 1, spring 16 will be compressed. Under the action of spring 16's own elasticity, collar 12 will be pushed to firmly adhere to the inner wall of housing 1, thereby ensuring the stability of collar 12 and oil needle body 2 after installation, and also improving the stability of oil needle body 2 during operation.

[0039] Mounting corner blocks 19 are fixedly installed on the top and bottom of the outer shell 1, and multiple mounting corner blocks 18 are fixedly connected to one side of the surface of the outer shell 1.

[0040] Specifically, the installation of corner block 18 and corner block 2 is designed to secure the carburetor. However, the installation directions of corner blocks 18 and 2 are different, allowing the carburetor to be installed in multiple different positions. This provides greater flexibility for carburetor installation and makes installation more convenient for users.

[0041] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
