Description

Technical Field

[0001] The utility model belongs to the technical field of automobile expansion water kettles, and particularly relates to a pressure-resistant automobile expansion water kettle. Background Art

[0002] An automobile expansion water kettle is an important part of an automobile cooling system. The filling port of the automobile expansion water kettle is sealed by screwing a sealing cover thereon. During the driving of the vehicle, bumps and vibrations will occur, and the screwing connection method will cause the phenomenon of thread slipping and loosening after a long time. The Chinese patent document "202022462547.7" discloses a limiting structure for the sealing cover of the filling port of an automobile expansion water kettle. The connecting column is clamped inside the connecting groove, then the positioning rod is clamped inside the positioning groove, and the outer side of the positioning rod is clamped with the cover groove, thereby limiting the sealing cover to prevent the sealing cover from loosening and increasing its sealing effect. However, its structure is complex, and when the sealing cover needs to be disassembled later, the operation is cumbersome, which is not conducive to later use. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a pressure-resistant automobile expansion water kettle aiming at the above defects. The sealing cover is not easy to loosen from the filling port, the sealing effect is better and more stable, and the separation of the sealing cover and the filling port is fast and convenient later, and the practicability is higher.

[0004] The technical solution adopted by the utility model to solve its technical problems is as follows: a pressure-resistant automobile expansion water kettle, including a kettle body, a filling port is opened at the top end of the kettle body, a sealing cover is screwed on the filling port, limiting columns are arranged on both sides of the filling port, a cavity is opened inside the limiting columns, through holes are opened on both sides inside the limiting columns, a limiting plate is detachably arranged at the top end of the sealing cover, connecting components are arranged at both sides of the bottom end of the limiting plate and are arranged vertically downward. The connecting component is composed of two connecting arms symmetrically arranged front and back at the bottom end of the limiting plate. A clamping block that forms a clamping fit with the through hole is arranged at one end of the connecting arm close to the through hole. Unlocking components are arranged at both ends of the limiting column to drive the clamping block to separate from the through hole. A top-out component is arranged inside the cavity to drive the clamping block and the connecting arm to move upward after the clamping block separates from the through hole.

[0005] Further, the unlocking component includes a guiding cylinder, a ejector rod, and a sliding block. The guiding cylinder is arranged at one end of the limiting column, and the guiding cylinder and the through hole are on the same central axis. The ejector rod is arranged inside the guiding cylinder. A sliding groove is opened on the inner wall of the guiding cylinder. The sliding block is arranged on the outer surface of the ejector rod and is slidably connected with the sliding groove. One end of the ejector rod penetrates through the guiding cylinder and extends into the through hole, and the other end extends outside the guiding cylinder.

[0006] Further, the ejection assembly includes a top plate disposed inside the cavity and return springs symmetrically disposed at the bottom end of the top plate. When the clamping block is engaged with the through hole, the bottom end of the connecting arm abuts against the top end of the top plate and applies a pressing force to the top plate, causing the return spring to undergo elastic deformation.

[0007] Further, a plurality of vertically arranged reinforcing ribs are spaced apart on the front and rear faces of the kettle body.

[0008] The beneficial effects of the present utility model are as follows:

[0009] Through the cooperative setting of the limit post, cavity, through hole, limit plate, connection assembly, clamping block, unlocking assembly, and ejection assembly, after the cover forms a connection with the filling port, the bottom end of the limit plate abuts against the top end of the cover. At the same time, the connection assembly and the clamping block enter the cavity of the limit post, and the clamping block forms a snap fit with the through hole, thereby locking the connection assembly and the clamping block in the cavity of the limit post. Then, the limit plate limits the cover, preventing the cover from moving upward due to unscrewing, making the sealing effect of the cover on the filling port better and more stable. After the clamping block is engaged with the through hole, it simultaneously squeezes the ejection assembly, causing it to undergo elastic deformation. When it is necessary to disassemble the cover, only need to press the unlocking assembly, and the unlocking assembly separates the clamping block from the through hole. The force that the ejection assembly is squeezed disappears, and it rebounds and resets, pushing the clamping block, connection assembly, and limit plate upward, and then the limit plate and connection assembly can be removed from the limit post, and the cover can be disassembled. Its structure is convenient and efficient to operate, convenient for later maintenance, and has higher practicability. Description of the Drawings

[0014] The following further describes the present utility model in conjunction with the drawings.

[0015] Refer to Figure 1-2As shown in the figure, a pressure-resistant expansion water kettle for an automobile includes a water kettle main body 1. An injection port 2 is opened at the top end of the water kettle main body 1. A sealing cover 3 is threadedly connected to the injection port 2. Internal threads are provided on the inner wall of the injection port 2, and external threads are provided at the connection between the sealing cover 3 and the injection port 2. Limiting columns 4 are provided on both sides of the injection port 2. A cavity 401 is opened inside the limiting column 4, and through holes 402 are opened on both sides inside the limiting column 4. A limiting plate 5 is detachably provided at the top end of the sealing cover 3. The bottom end of the limiting plate 5 abuts against the top end of the sealing cover 3. Connection components arranged vertically downward are provided on both sides of the bottom end of the limiting plate 5. The connection components are composed of two connecting arms 6 symmetrically arranged front and back at the bottom end of the limiting plate 5. The two connecting arms 6 are arranged at intervals front and back. Specifically, four connecting arms 6 are provided at the bottom end of the limiting plate 5, arranged in two pairs symmetrically. A clamping block 601 that forms a snap fit with the through hole 402 is provided at one end of the connecting arm 6 close to the through hole 402. The distance between the two clamping blocks 601 is greater than the inner diameter of the cavity 401. When the two connecting arms 6 enter the cavity 401 inside the limiting column 4, the clamping block 601 is restricted by the inner wall of the cavity 401, causing the two connecting arms 6 to be squeezed and elastically deformed, approaching each other until the clamping block 601 moves to the through hole 402. The restricted force disappears, the connecting arm 6 rebounds, the clamping block 601 enters the through hole 402 and forms a snap fit. The connecting arm 6 abuts against the inner wall of the cavity 401, and then the connecting arm 6 and the clamping block 601 form a lock in the limiting column 4, and then the limiting plate 5 is limited. At the same time, the limiting plate 5 limits the sealing cover 3, preventing the sealing cover 3 from moving upward due to thread loosening, making the sealing effect of the sealing cover 3 on the injection port 2 better and more stable.

[0016] Unlocking components 7 for driving the clamping block 601 to separate from the through hole 402 are provided at both ends of the limiting column 4. When it is necessary to disassemble the sealing cover 3, the unlocking components 7 can be directly operated outside the limiting column 4 to move the clamping block 601 out of the through hole 402, so that the clamping block 601 and the connecting arm 6 can be moved out of the limiting column 4 to disassemble and separate the limiting plate 5 and the sealing cover 3. The unlocking components 7 include a guide cylinder 701, a top rod 702, and a slider 703. The guide cylinder 701 is provided at one end of the limiting column 4, and the guide cylinder 701 and the through hole 402 are on the same central axis. The top rod 702 is provided inside the guide cylinder 701. A sliding groove 704 is opened on the inner wall of the guide cylinder 701. The slider 703 is provided on the outer surface of the top rod 702 and is slidably connected to the sliding groove 704. One end of the top rod 702 penetrates through the guide cylinder 701 and extends into the through hole 402, and the other end extends outside the guide cylinder 701. After the clamping block 601 forms a snap fit with the through hole 402, one end of the top rod 702 abuts against the clamping block 601, and the other end extends outside the guide cylinder 701. By pressing the top rod 702, the top rod 702 is driven to move towards the cavity 401 side, and the slider 703 slides along the sliding groove 704, so that the top rod 702 separates the clamping block 601 from the through hole 402.

[0017] Inside the cavity 401, there is an ejection assembly that drives the latch 601 and the connecting arm 6 to move upward after the latch 601 is separated from the through hole 402. When the latch 601 is separated from the through hole 402, the ejection assembly jacks up the connecting arm 6, facilitating the rapid separation of the latch 601 from the through hole 402 and enabling the quick removal of the limiting plate 5. The separation of the cover from the filling port is fast and convenient, with higher practicality. The ejection assembly includes a top plate 801 disposed inside the cavity 401 and return springs 802 symmetrically arranged at the bottom end of the top plate 801. When the latch 601 is engaged with the through hole 402, the bottom end of the connecting arm 6 abuts against the top end of the top plate 801 and applies a pressing force to the top plate 801, causing the return spring 802 to undergo elastic deformation. After the latch 601 is separated from the through hole 402, the restricted force on the top plate 801 disappears, and the return spring 802 rebounds, driving the top plate 801 to move upward, causing the latch 601, the connecting arm 6, and the limiting plate 5 to move upward, facilitating the operator to quickly remove the limiting plate 5, enabling the detachable cover. Its structure is convenient and efficient to operate, convenient for later maintenance, and has higher practicality.

[0018] On the front and rear end faces of the kettle body 1, a plurality of vertically arranged reinforcing ribs 9 are spaced apart. The reinforcing ribs 9 are used to increase the structural strength of the kettle body 1, thereby improving the structural stability and pressure resistance of the kettle body 1.

[0019] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
