[0002] The compensator is also customarily called an expansion joint or a telescopic joint. It consists of a corrugated pipe (an elastic element) that forms its working body and accessories such as end pipes, brackets, flanges, and conduits. It belongs to a compensating element. Utilizing the effective telescopic deformation of its working body corrugated pipe to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction, etc., or to compensate for the axial, lateral, and angular displacements of pipelines, conduits, containers, etc. It can also be used for noise reduction and vibration damping.

[0003] However, the existing compensator has a single design. When the compensator is connected to the pipeline, a large number of screws and bolts are required for fixation. This method is time-consuming and laborious, and the screws and bolts are exposed to the outside for a long time, making the screws and bolts prone to rust, and thus difficult to disassemble, thereby reducing work efficiency. For this reason, we propose a compensator with an exhaust structure to solve the above problems. Content of the Utility Model

[0023] Please refer to Figures 1-4 , an embodiment provided by the present utility model: A compensator with an exhaust structure, including a first connecting pipe 1, a connecting plate 2 and a screw 3. The outer end of the first connecting pipe 1 is fixedly connected with a connecting plate 2. Three groups of screws 3 are threadedly connected to the surface of the connecting plate 2. The lower side of the screw 3 is threadedly connected with a second connecting pipe 4. A fixing mechanism is arranged at the lower end of the first connecting pipe 1;

[0024] The fixing mechanism includes a clamping block 7, a card slot 9 and a movable slot 11. The lower end of the first connecting pipe 1 is fixedly connected with a first connecting sleeve 5. Six groups of clamping blocks 7 are fixedly connected to the lower surface of the first connecting sleeve 5. The upper end of the second connecting pipe 4 is fixedly connected with a second connecting sleeve 6. A card slot 9 is opened on the upper surface of the second connecting sleeve 6. A movable slot 11 is opened on the lower side of the card slot 9. A buckle assembly is arranged in the movable slot 11;

[0025] By using the fixing mechanism and the buckle assembly in cooperation, this device solves the problems of the single design of the existing compensator, which requires a large number of screws and bolts for fixing, making it difficult to disassemble and thus reducing work efficiency.

[0026] Furthermore, the buckle assembly includes a movable sleeve 13, a return spring 14 and a limit block 16. A spring groove 12 is formed in the inner wall of the movable groove 11. The movable sleeve 13 is movably connected in the spring groove 12. A return spring 14 is arranged in the movable sleeve 13. The two ends of the return spring 14 abut against the spring groove 12 and the movable sleeve 13. A limit block 16 is fixedly connected to the outer end of the movable sleeve 13. As Figure 4 shown, this structure is used to, through the cooperation of the limit block 16 and the movable sleeve 13, make the clamping block 7 abut against the limit block 16, so that the corresponding movable sleeve 13 moves into the spring groove 12 and at the same time compresses the return spring 14, and by the limit block 16 abutting against the inner resistance block 17, the firmness is enhanced.

[0027] Furthermore, the clamping block 7 is T-shaped, the clamping groove 9 is T-shaped, the movable groove 11 is flat and its diameter is adapted to the clamping block 7, and the movable groove 11 is communicated with the clamping groove 9. As Figure 4 shown, this structure is used to, because the clamping block 7 and the clamping groove 9 are T-shaped, it is convenient for the clamping block 7 to be inserted into the clamping groove 9 for fixing, and the structure is simple and convenient for assembly and disassembly.

[0028] Furthermore, a connecting block 8 is fixedly connected to the outer side of the clamping block 7. The connecting block 8 and the limit block 16 are opposite triangles. Resistance blocks 17 are arranged on the surfaces of both the connecting block 8 and the limit block 16. As Figure 2 shown, this structure is used to form a fastening fit through the resistance blocks 17 on the inner sides where the connecting block 8 abuts against the limit block 16, so as to prevent loosening.

[0029] Furthermore, exhaust holes 10 are annularly formed on the outer surface of the second connecting sleeve 6, and the exhaust holes 10 penetrate through the movable groove 11. As Figure 3 shown, this structure is used to, through the cooperation of the buckle assembly and the exhaust holes 10, enable the device not to expand rapidly during the exhaust process, slow down the exhaust gas fluidity, enhance the smoothness of the exhaust, and thus more effectively protect the bellows.

[0030] Furthermore, a limit ring 15 is fixedly connected to the inner end of the movable sleeve 13. The diameter of the limit ring 15 is adapted to the spring groove 12. As Figure 4 shown, this structure is used to, through the adaptation of the limit ring 15 to the spring groove 12, prevent the movable sleeve 13 from disengaging from the spring groove 12 and enhance the stability of the device.

[0031] Working principle: During installation, as Figure 1 shown, the staff connects and fixes the first connecting pipe 1 to the second connecting pipe 4 through the screw 3 on the outer side of the connecting plate 2.Figure 2 and Figure 3 As shown, at the same time, the clamping block 7 at the lower end of the first connecting pipe 1 is inserted along the slot 9 at the second connecting sleeve 6. When the clamping block 7 enters the movable slot 11 after being inserted into the slot 9, as Figure 4 shown, rotate the first connecting pipe 1 clockwise to drive the clamping block 7 to push the limiting block 16 towards the spring slot 12 for extrusion. While the limiting block 16 moves, it drives the movable sleeve 13, causing the return spring 14 to contract. The connecting block 8 at the outer end of the clamping block 7 abuts against the limiting block 16, and the inner resistance block 17 meshes with the limiting block 16 through the abutment of the connecting block 8 and the limiting block 16 to form a fastening fit, thereby achieving the function of fixing the first connecting pipe 1 and the second connecting pipe 4. This method is simple and fast to operate, without the need for bolts for fixation, which improves the installation efficiency. During exhaust, increase the rotation angle of the first connecting pipe 1. Through the movement of the limiting block 16, the exhaust hole 10 opened on the surface of the second connecting sleeve 6 is parallel to the inside of the movable slot 11, realizing opening and closing, and playing a guiding role. Through the combined use of the buckle assembly and the exhaust hole 10, the device will not expand rapidly during the exhaust process, thus slowing down the waste. And during disassembly, just rotate the first connecting pipe 1 counterclockwise to drive the clamping block 7, and then pull out the clamping block 7 in the slot 9 and the movable slot 11 to complete the disassembly. At the same time, under the action of the return spring 14 rebounding, the movable sleeve 13 and the limiting block 16 are restored to their original positions. The above is the entire working principle of the present invention.
