[0002] In the field of gasoline engine technology, the installation of the thermostat remains a key factor affecting engine performance and maintenance efficiency. Traditional gasoline engine thermostat installation methods have many drawbacks, especially in terms of precise positioning.

[0003] During installation, operators often need to spend a lot of time adjusting the position of the thermostat to ensure it is accurately aligned with the installation location, which reduces installation efficiency. Even a slight positional deviation may cause the bolts to fail to screw in properly, or the thermostat to shift after tightening, making it difficult for the thermostat to fit tightly with other components. This results in a loose connection between the thermostat and other components, increasing the probability of future malfunctions.

[0004] Therefore, developing a gasoline engine thermostat installation structure that enables rapid positioning, secure connection, and reliable sealing is of significant practical importance. This utility model presents a gasoline engine thermostat rapid positioning and installation clip structure specifically addressing the shortcomings of the aforementioned existing technologies. Utility Model Content

[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide a quick-positioning and installation clip structure for a gasoline engine thermostat. This structure offers advantages such as quick positioning and installation, a secure connection, and reliable sealing. It solves the problem that during installation, operators often need to spend a lot of time adjusting the position of the thermostat to accurately align it with the installation location, thus reducing installation efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-positioning and installation buckle structure for a gasoline engine thermostat, comprising an installation part, a connecting pipe, and a thermostat body. A sealing slip ring is fixedly connected to the right side of the surface of the thermostat body. Limit grooves are formed around the circumference of the sealing slip ring. A sealing limiting strip is formed around the circumference of the inner wall of the connecting pipe to cooperate with the limiting grooves. The surface of the sealing limiting strip fits against the inner wall of the limiting groove. A rotating ring is rotatably connected to the left end of the connecting pipe. A convex locking block is fixedly connected around the circumference of the inner wall of the rotating ring. Four evenly distributed concave locking blocks that cooperate with the convex locking blocks are fixedly connected to the left side of the sealing slip ring. Positioning threaded holes are formed around the right side of the surface of the installation part. Nut seats are fixedly connected around the circumference of the left side of the surface of the connecting pipe. Fixing bolts are threaded into the internal parts of the nut seats, and the positions of the four nut seats correspond one-to-one with the positions of the concave locking blocks.

[0007] As a preferred embodiment of this utility model, anti-loosening seats are fixedly connected to all four sides of the rotating ring surface. The anti-loosening seats have through-hole fixing threads on their surfaces, and the positions of the four anti-loosening seats correspond one-to-one with the convex locking blocks.

[0008] In a preferred embodiment of this invention, a first sealing washer is fixedly connected to the left side of the rotating ring, and a second sealing washer that cooperates with the first sealing washer is fixedly connected to the right side of the mounting part.

[0009] In a preferred embodiment of this invention, a sealed bearing is fixedly connected to the left end of the connecting pipe, and the surface of the right end of the rotating ring is fixedly connected to the inner wall of the sealed bearing.

[0010] As a preferred embodiment of this utility model, four limiting blocks corresponding one-to-one with the concave locking blocks are fixedly connected to the left side of the sealing slip ring, and one side of the limiting blocks is in contact with one side of the concave locking blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model features a sealing slip ring on the right side of the thermostat body surface, with a limiting groove around the sealing slip ring that cooperates with the sealing limiting strip around the inner wall of the connecting pipe. This achieves precise positioning and a good sealing effect, preventing coolant leakage. The rotating ring at the left end of the connecting pipe and the convex locking block on its inner wall cooperate with the concave locking block on the left side of the sealing slip ring, facilitating quick and easy installation and removal of the thermostat and improving installation efficiency. The positioning threaded hole on the right side of the mounting part surface cooperates with the nut seat and fixing bolt on the left side of the connecting pipe surface, further ensuring the firmness of the thermostat installation.

[0014] 2. This utility model, by setting anti-loosening seats and fixing threaded holes fixedly connected around the surface of the rotating ring, ensures that after the thermostat is installed, the fixing threaded holes, positioning threaded holes, and nut seats are on the same axis. The fixing bolts are screwed into the fixing threaded holes, and the left end of the fixing bolts is screwed into the positioning threaded holes, which firmly fixes the connecting pipe, rotating ring, and thermostat body on the right side of the mounting part. This effectively prevents the rotating ring from loosening, thereby ensuring a tight fit between the convex and concave locking blocks. This further enhances the stability and reliability of the thermostat installation, reduces the risk of thermostat position displacement or loose connection due to the rotating ring loosening, and improves the service life and safety of the entire structure.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a quick-positioning and installation clip structure for a gasoline engine thermostat, including an installation part 1, a connecting pipe 2, and a thermostat body 3. A sealing slip ring 4 is fixedly connected to the right side of the surface of the thermostat body 3. Limit grooves 5 are formed around the sealing slip ring 4. Sealing limit strips 6, which cooperate with the limit grooves 5, are formed around the inner wall of the connecting pipe 2. The surface of the sealing limit strip 6 fits against the inner wall of the limit groove 5. The sealing limit strip 6 is made of a thermally expanding material; when the thermostat body 3 is working, the temperature rises, and the sealing limit strip 6 expands to improve the sealing effect. The left end of the connecting pipe 2... A rotating ring 7 is rotatably connected. A convex locking block 8 is fixedly connected to the inner wall of the rotating ring 7. Four evenly distributed concave locking blocks 9 that cooperate with the convex locking blocks 8 are fixedly connected to the left side of the sealing slip ring 4. Positioning threaded holes 10 are opened on the right side of the surface of the mounting part 1. Nut seats 11 are fixedly connected to the left side of the connecting pipe 2. The internal threads of the nut seats 11 are connected to fixing bolts 12, and the positions of the four nut seats 11 correspond one-to-one with the positions of the concave locking blocks 9. A sealing quick connector is connected to the right end of the connecting pipe 2 for connecting to the external coolant pipeline.

[0022] refer to Figure 1Anti-loosening seats 13 are fixedly connected to all four sides of the surface of the rotating ring 7. The surface of the anti-loosening seat 13 has a fixed threaded hole that runs through from left to right, and the four anti-loosening seats 13 correspond one-to-one with the positions of the convex locking blocks 8.

[0023] As a technical optimization of this utility model, by setting anti-loosening seats 13 and their fixed threaded holes to be fixedly connected around the surface of the rotating ring 7, after the thermostat is installed, the fixed threaded holes, positioning threaded holes 10 and nut seats 11 are on the same axis. The fixing bolts 12 are screwed into the fixing threaded holes, and the left end of the fixing bolts 12 is screwed into the positioning threaded holes 10, which firmly fixes the connecting pipe 2, the rotating ring 7 and the thermostat body on the right side of the mounting part 1, effectively preventing the rotating ring 7 from loosening. This ensures the tight fit between the convex locking block 8 and the concave locking block 9, further enhancing the stability and reliability of the thermostat installation, reducing the risk of thermostat position displacement or loose connection due to the loosening of the rotating ring 7, and improving the service life and safety of the entire structure.

[0024] refer to Figure 1 A first sealing washer 14 is fixedly connected to the left side of the rotating ring 7, and a second sealing washer 15 that cooperates with the first sealing washer 14 is fixedly connected to the right side of the mounting part 1.

[0025] As a technical optimization of this utility model, by setting the first sealing gasket 14 on the left side of the rotating ring 7 and the second sealing gasket 15 on the right side of the mounting part 1 to cooperate with each other, the sealing performance of the thermostat mounting point is improved. These two sealing gaskets effectively prevent coolant leakage from the connection between the rotating ring 7 and the mounting part 1, avoiding damage to other engine components caused by coolant leakage and ensuring the normal operation of the engine cooling system. At the same time, good sealing performance also helps to improve engine performance and efficiency, reducing energy waste and the probability of malfunctions.

[0026] refer to Figure 1 A sealed bearing 16 is fixedly connected to the left end of the connecting pipe 2, and the surface of the right end of the rotating ring 7 is fixedly connected to the inner wall of the sealed bearing 16.

[0027] As a technical optimization of this utility model, by setting a sealed bearing 16 fixedly connected to the left end of the connecting pipe 2, the rotating ring 7 can rotate flexibly while ensuring the sealing between the rotating ring 7 and the connecting pipe 2. The setting of the sealed bearing 16 not only facilitates the operation of the rotating ring 7 and the alignment and cooperation of the convex locking block 8 and the concave locking block 9, but also prevents coolant leakage from the connection between the rotating ring 7 and the connecting pipe 2, further improving the reliability and stability of the entire thermostat installation structure and ensuring the normal installation and use of the thermostat.

[0028] refer to Figure 3The left side of the sealing slip ring 4 is fixedly connected with four limiting blocks 17 that correspond one-to-one with the concave block 9. One side of the limiting block 17 is in contact with one side of the concave block 9.

[0029] As a technical optimization of this utility model, the limiting block 17 fixedly connected to the left side of the sealing slip ring 4 corresponds one-to-one with the concave locking block 9, playing an important limiting role. During the installation of the thermostat, the limiting block 17 can accurately restrict the position of the concave locking block 9, ensuring the correct fit between the convex locking block 8 and the concave locking block 9, avoiding installation difficulties or insecure installation caused by positional deviation of the concave locking block 9. At the same time, the limiting block 17 can also enhance the structural strength of the concave locking block 9 to a certain extent, improve its service life, and ensure the stability and reliability of the thermostat installation structure.

[0030] refer to Figure 3 An anti-loosening washer 18 is fitted on the left side of the surface of the fixing bolt 12. The anti-loosening washer 18 is made of silicone.

[0031] As a technical optimization of this utility model, the silicone anti-loosening washer 18 fitted on the left side of the fixing bolt 12 provides excellent anti-loosening effect. The silicone material has a certain degree of elasticity and friction, effectively preventing the fixing bolt 12 from loosening during use and ensuring a tight connection between the nut seat 11 and the positioning threaded hole 10. Simultaneously, the silicone material also has a certain degree of corrosion resistance, maintaining good performance in environments such as coolant, extending the service life of the anti-loosening washer 18, and further improving the stability and reliability of the thermostat installation structure.

[0032] The working principle and usage process of this utility model are as follows: When installing the thermostat, first insert the thermostat body 3 into the connecting pipe 2 from the right end of the connecting pipe 2. Align the limiting groove 5 on the sealing slip ring 4 with the sealing limiting strip 6 on the inner wall of the connecting pipe 2. Push the thermostat body 3 to the leftmost end of the connecting pipe 2 to achieve initial positioning. Then, rotate the rotating ring 7 at the left end of the connecting pipe 2 so that the convex locking block 8 on the inner wall of the rotating ring 7 engages with the concave locking block 9 on the left side of the sealing slip ring 4, completing the quick installation and positioning of the thermostat. Then, with the fixing threaded hole, positioning threaded hole 10 and nut seat 11 on the same axis, screw the fixing bolt 12 into the fixing threaded hole and screw the left end of the fixing bolt 12 into the positioning threaded hole 10 to firmly fix the connecting pipe 2, rotating ring 7 and thermostat body on the right side of the mounting part 1, preventing the rotating ring 7 from loosening and maintaining the tight fit between the convex locking block 8 and the concave locking block 9. During installation, the first sealing washer 14 on the left side of the rotating ring 7 and the second sealing washer 15 on the right side of the mounting part 1 fit together, effectively preventing coolant leakage from the connection between the rotating ring 7 and the mounting part 1. Finally, connect the sealing quick connector at the right end of the connecting pipe 2 to the external coolant pipeline to ensure smooth coolant flow and normal operation of the gasoline engine cooling system. When it is necessary to disassemble the thermostat, simply reverse the above steps: first loosen the fixing bolt 12, then rotate the rotating ring 7 to separate the convex locking block 8 from the concave locking block 9, and finally remove the thermostat body 3 from the connecting pipe 2.
