Description

Technical Field

[0001] The utility model relates to the technical field of turbojet engines, in particular to a diffuser used for turbojet engines. Background Art

[0002] In the design of turbojet engines, the diffuser is an important component, which is responsible for decelerating the high-speed airflow and increasing its static pressure so as to drive the compressor and turbine more efficiently. However, the existing turbojet engine diffuser design has some shortcomings in installation and removal.

[0003] Traditional diffusers are usually connected to other engine components by bolts, welding or other fixing methods. Although such a design can provide sufficient strength and stability, it is particularly inconvenient when the diffuser needs to be maintained, replaced or upgraded. Due to the complexity and fixity of the connection method, the installation and removal of the diffuser often requires a lot of time and manpower, which not only increases maintenance costs, but may also affect the maintenance efficiency of the engine. Utility Model Content

[0004] The purpose of the utility model is to provide a diffuser for a turbojet engine to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a diffuser for a turbojet engine, comprising a shell, a diffuser, a connecting tube and a clamping structure, a connecting tube is arranged on the left side of the diffuser, the top and the bottom of the connecting tube are provided with clamping grooves, two clamping structures are arranged on the top and the bottom of the shell, the clamping structure comprises a bracket, two springs, a movable plate, a clamping block and a pull rod, the bracket is arranged at the bottom of the shell, the two springs are located in the bracket, and one end of the two springs is connected to the bottom of the shell, the bottom of the movable plate is connected to the other end of the two springs, the clamping block is arranged at the top of the movable plate, and the clamping block movably passes through the clamping groove of the connecting tube, the pull rod movably passes through the bottom of the shell, and one end of the pull rod is connected to the bottom of the movable plate.

[0006] Preferably, a handle is provided at the other end of the pull rod.

[0007] Preferably, the distance between the two clamping structures is the same as the diameter of the connecting tube.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the utility model provides great convenience for the installation and removal of the diffuser by arranging two clamping structures in the housing. The two clamping structures can ensure a stable connection between the diffuser and the housing, while enabling rapid assembly and disassembly operations. This not only greatly saves maintenance time and improves work efficiency, but also reduces the difficulty of operation, making the replacement and maintenance of the diffuser simpler and faster.

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] See also Figure 1-3 The utility model provides a diffuser for a turbojet engine, comprising a shell 1, a diffuser 2, a connecting tube 3 and a clamping structure 4. The left side of the diffuser 2 is provided with a connecting tube 3, and the top and bottom of the connecting tube 3 are provided with clamping grooves. Two clamping structures 4 are provided at the top and bottom of the shell 1. The clamping structure 4 comprises a bracket 41, two springs 42, a movable plate 43, a clamping block 44 and a pull rod 45. The bracket 41 is arranged at the bottom of the shell 1, the two springs 42 are located in the bracket 41, and one end of the two springs 42 is connected to the bottom of the shell 1, the bottom of the movable plate 43 is connected to the other end of the two springs 42, the clamping block 44 is arranged at the top of the movable plate 43, and the clamping block 44 movably passes through the clamping groove of the connecting tube 3, the pull rod 45 movably passes through the bottom of the shell 1, and one end of the pull rod 45 is connected to the bottom of the movable plate 43.

[0015] Specifically, a handle 46 is provided at the other end of the pull rod 45 .

[0016] Specifically, the distance between the two clamping structures 4 is the same as the diameter of the connecting tube 3 .

[0017] Working principle: During the installation of the diffuser 2, the user only needs to pull the rod 45 outward through the handle 46 to allow the block 44 to enter the bracket 41, and the spring 42 is compressed. Next, insert the connecting tube 3 of the diffuser 2 between the two clamping structures 4. Since the distance between the two clamping structures 4 is the same as the diameter of the connecting tube 3, the connecting tube 3 can be smoothly inserted. When the connecting tube 3 is fully inserted, release the rod 45, and the elastic restoring force of the spring 42 will push the moving plate 43 to move upward, so that the block 44 passes through the slot of the connecting tube 3. At this time, the cooperation between the block 44 and the slot firmly fixes the diffuser 2 in the housing 1, completing the installation process of the diffuser 2.

[0018] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
