Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a high-sealing cylinder head. Background Technology

[0002] In mechanical engineering, the cylinder head is one of the most important components in mechanical equipment such as engines. The existing cylinder head fixing methods mostly use bolts for fastening, which have insufficient locking force, are inconvenient to adjust, and are prone to loosening under long-term vibration or high temperature environment, resulting in gasket failure and leakage.

[0004] Each pair of pull-type locking structures includes: a pair of fixing blocks, a pair of combination rods, a guide frame, a pair of pull rods, a pair of mounting brackets, fixing screws, a pair of elastic ratchet locking components, a pair of locking blocks, and a pair of moving blocks;

[0005] A pair of fixing blocks are installed on the side wall of the cylinder head, a pair of combined insert rods are installed on the lower wall of the pair of fixing blocks, a guide bracket is installed on the side wall of the cylinder block connector, the upper ends of a pair of tie rods are movably installed at the lower ends of the pair of combined insert rods, a pair of mounting brackets are installed below the guide bracket, a fixing screw is movably installed on a pair of mounting brackets, a pair of elastic ratchet clamping assemblies are installed on the outer wall of a pair of mounting brackets, a pair of locking blocks are installed at both ends of the fixing screw, a pair of moving blocks are installed on the fixing screw through threaded engagement, and the lower ends of a pair of tie rods are movably installed on a pair of moving blocks.

[0006] Preferably, the sealing gasket is positioned and installed on the cylinder head by a retaining pin.

[0007] Preferably, the sealing gasket adopts a filled multi-layer structure.

[0008] Preferably, a positioning rod is provided on a pair of combined insertion rods.

[0009] Preferably, pairs of tie rods are connected to the combined insert rod and the moving block via rotating hinges.

One end of the two pairs of spring support rods is installed inside the mounting groove, and the ratchet clasp is embedded in the mounting groove and connected to the other end of the two pairs of spring support rods.

[0012] Preferably, the inner wall of the locking block has a locking groove for engaging with the ratchet retaining ring.

[0013] Beneficial effects

[0014] This utility model provides a high-sealing cylinder head with the following advantages: This solution uses a pull-type locking structure, adding a pull-type fixing structure to the traditional bolt fastening. By adjusting the screw to drive the moving block, the pull rod is driven to quickly tighten or loosen the cylinder head, simplifying the disassembly and assembly process and improving maintenance efficiency. The elastic ratchet locking component cooperates with the locking groove on the locking block to form a self-locking mechanism, preventing loosening caused by vibration or pressure changes and ensuring long-term stability. At the same time, through the filling multi-layer structure of the sealing gasket and the positioning installation of the fixing pin, the sealing performance at the connection between the cylinder head and the cylinder body is significantly improved, effectively preventing liquid or gas leakage. This solves the problems of existing cylinder head fixing methods that mostly use bolt fastening, which have insufficient locking force, are inconvenient to adjust, and are prone to loosening under long-term vibration or high-temperature environments, leading to gasket failure and leakage.

Detailed Implementation

[0022] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example: Please refer to Figure 1-6 This utility model provides a technical solution: a high-sealing cylinder head. This solution takes into account that the existing engine cylinder head is only connected and fixed by a single bolt, which has poor fixing stability. With the increase of use time, it will loosen, and the gasket will shift in position due to vibration, thus affecting the sealing effect. Based on the above, this invention sets up the following technical means.

[0024] Specifically, this device includes at least: cylinder block connector 1, cylinder head 2, sealing gasket 3, a pair of fixing blocks 4, a pair of combined insert rods 5, guide frame 6, a pair of tie rods 7, a pair of mounting brackets 8, fixing screws 9, a pair of elastic ratchet clamping assemblies, a pair of locking blocks 10, and a pair of moving blocks 11;

[0025] Each pair of spring-loaded ratchet locking components includes: a retaining collar 15, a mounting groove 16, two pairs of spring support rods 17, and a ratchet 18;

[0026] The cylinder block connector 1 and cylinder head 2 form the main body of the equipment. During assembly, the sealing gasket 3 is positioned and installed on the lower wall of the cylinder head 2 using the fixing pin 12. The combined insert rod 5, which is installed on the cylinder head 2 through the fixing block 4, passes through the guide bracket 6 installed on the side wall of the cylinder block connector 1 via the positioning rod 13, thereby limiting the horizontal installation accuracy of the cylinder head 2. Then, the tie rod 7 is installed at the lower end of the combined insert rod 5, and the fixing screw 9, which is installed on the mounting bracket 8, is rotated. The fixing screw 9 in this solution uses both positive and negative threads. The screw and the fixed screw 9 rotate and drive the moving block 11 to move to both sides through the threaded engagement. The moving block 11 pulls and stretches the tie rod 7 through the rotating hinge seat 14, thereby cooperating with the combined insert rod 5 to drive the cylinder head 2 and the cylinder body connecting piece 1 to achieve a stable and sealed connection. At the same time, the ratchet retaining ring 18 installed on the fixed collar 15 through the spring support rod 17 will be engaged into the retaining groove 19 opened on the locking blocks 10 at both ends of the fixed screw 9 by the deformation elastic force of the spring support rod 17. The ratchet structure prevents loosening due to reverse rotation.

[0027] More specifically, a pair of fixing blocks 4 are installed on the side wall of the cylinder head 2, a pair of combined insert rods 5 are installed on the lower wall of the pair of fixing blocks 4, a guide bracket 6 is installed on the side wall of the cylinder block connector 1, the upper ends of a pair of tie rods 7 are movably installed at the lower end of the pair of combined insert rods 5, a pair of mounting brackets 8 are installed below the guide bracket 6, a fixing screw 9 is movably installed on the pair of mounting brackets 8, a pair of elastic ratchet clamping components are installed on the outer wall of the pair of mounting brackets 8, a pair of locking blocks 10 are installed at both ends of the fixing screw 9, a pair of moving blocks 11 are installed on the fixing screw 9 through threaded engagement, and the lower ends of a pair of tie rods 7 are movably installed on a pair of moving blocks 11;

[0028] The fixing collar 15 is installed on the outer wall of the mounting bracket 8. The mounting groove 16 is opened on the fixing collar 15. One end of the two pairs of spring support rods 17 is installed inside the mounting groove 16. The ratchet clasp 18 is embedded in the mounting groove 16 and connected to the other end of the two pairs of spring support rods 17.

[0029] In the specific implementation process, the sealing gasket 3 is further positioned and installed on the cylinder head 2 by the fixing pin 12.

[0030] In the specific implementation process, the sealing gasket 3 further adopts a filled multi-layer structure.

[0031] In the specific implementation process, a positioning rod 13 is further provided on a pair of combined insertion rods 5.

[0032] In the specific implementation process, furthermore, a pair of pull rods 7 are connected to the combined plug rod 5 and the moving block 11 through the rotating hinge seat 14.

[0033] In the specific implementation process, furthermore, a locking groove 19 is provided on the inner wall surface of the locking block 10 for locking together with the ratchet retaining ring 18.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
