[0002] A fan connector is a connection component used to connect two fan components. Through the connection work of the connector, when a driving device is driving, the shafts between the two fan components can be simultaneously started and rotated. The common structure of the connector in the existing market is the structure of a coupling. It generally consists of two parts. After connecting the two parts to the shafts of the two fan components respectively, the two parts are connected by a key or a clamping connection method to complete the connection work of the two parts, thus completing the connection work of the shafts of the two fan components. However, for the above-mentioned connector structure, the middle connection structure of the whole structure is fixed. When the two fan components rotate and start simultaneously, since both of them will generate corresponding vibration work, it will inevitably lead to different degrees of deviation of the shafts of the two fan components. Therefore, the fixed structure in the middle of the traditional connector is prone to breakage during the long-term operation of the fan components. At the same time, due to the existence of the traditional fixing mechanism, the requirement for the concentricity of the shafts between the two fan components is very high during the installation of the fan components, so the installation requirement for the whole connector is very high;

[0003] For example, in the coupling structure disclosed in the long-shaft coupling for blast furnace exhaust fans with the application number 201120244241.2, the middle of the first coupling and the second coupling is set as a fixed structure, which will affect the normal connection work of the first coupling and the second coupling when the shafts at the top of the first coupling and the second coupling vibrate and deviate for a long time. Summary of the Invention

[0004] The purpose of the utility model is to provide a flexible fan connector to solve the problems in the above background technology that the current market connectors have high requirements for the concentricity during the installation of the shafts of the fan components, and the couplings will break when the two shafts vibrate and deviate for a long time.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A flexible fan connector includes a flexible component and installation components at the top ends on both sides thereof. The installation components are used to connect the two fan shafts on the outside, and the installation components and the flexible component are of a detachable installation structure.

[0006] Preferably, the flexible component includes a connecting piece and two connecting cylinders. The two connecting cylinders are integrally installed with the connecting piece in the middle, and the connecting piece is made of anti-oxidation PPA6 plastic material.

[0007] Preferably, the flexible component further includes a mounting component, and the mounting component is any one of a snap ring or a mounting groove;

[0008] The snap ring is integrally mounted on the outer side of the connecting cylinder and is used for snap-fitting installation with the mounting component;

[0009] The mounting groove is inlaid on the outside of the connecting cylinder.

[0010] Preferably, the mounting component includes a mounting cylinder and a snap-fitting component, and the snap-fitting component is any one of a snap groove and a snap block;

[0011] The snap groove is inlaid on the inner side of the mounting cylinder and is used for snap-fitting of the snap ring inside, and the snap block is snap-fitted with the mounting groove;

[0012] The middle of the snap ring and the outer wall of the snap groove are equiangularly distributed with screw grooves penetrating through, and mounting screws are threadedly connected inside the screw grooves for mounting the mounting component and the flexible component.

[0013] Preferably, the outer wall of the mounting cylinder is also equiangularly penetrated with reserved grooves, and a threaded structure is arranged inside the reserved grooves for threaded connection with the connecting component.

[0014] Preferably, the connecting component includes a threaded post and a connecting key. The outer wall of the threaded post is provided with threads for threaded connection with the inside of the reserved groove, and a connecting key is integrally mounted at the bottom of the threaded post. The top end of the threaded post is set as a polygonal structure and is snap-fitted with the polygonal structure at the top end of the reserved groove.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: This flexible fan connector;

[0016] A flexible component is arranged between the two mounting components. Therefore, when the fan shafts inside the two mounting components vibrate during high-speed rotation, the connecting pieces inside the flexible component can perform buffering and shock-absorbing work. Thus, it is not easy to occur the phenomenon of intermediate fracture. Moreover, the flexible setting enables the two fan components to have a certain deviation in concentricity during installation, but it will not affect the normal and efficient operation of the two fan components. The installation is convenient and the service life is longer;

[0017] The mounting component and the flexible component can also be flexibly disassembled and installed. Therefore, when the flexible component or the mounting component is damaged, the repair and replacement work can be carried out flexibly. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0025] Please refer to Figures 1-5 , the present utility model provides a technical solution: a flexible fan connector, including a flexible component 1 and mounting components 2 at both top ends thereof. The mounting components 2 are used to connect two fan shafts on the outside, and the mounting components 2 and the flexible component 1 are of a detachable mounting structure;

[0026] The present application provides a flexible fan connector with a flexible component 1. Specifically, when in use, first, only the intermediate shafts of two external fan components need to be respectively engaged into the mounting components 2 on both sides of the flexible component 1 for installation. At this time, when starting an external driving device to drive the shaft of one side of the fan component to rotate, the shaft will drive the external mounting component 2 to rotate. Then, under the connection action of the flexible component 1, the mounting component 2 at the other top end will drive the shaft engaged with it to rotate, thus achieving the rotation of the shafts of the two fan components;

[0027] When the shafts of the two fan components rotate, due to the presence of the flexible component 1, it will buffer the vibration when the shafts of the two vibrate, ensuring that there is no risk of breakage and extending the service life of the entire connector.

[0028] Among them, according to Figures 1-3 As shown, the flexible component 1 includes a connecting piece 11 and two connecting cylinders 12. The connecting piece 11 is integrally installed in the middle of the two connecting cylinders 12, and the connecting piece 11 is made of anti-oxidation PPA6 plastic material;

[0029] Specifically, since the connecting piece 11 is made of anti-oxidation PPA6 plastic material, when the installation component 2 on one side drives the connecting cylinder 12 to rotate, the connecting piece 11 in the middle will rotate. And because it has a spiral structure and the material is also PPA6 plastic material, it can achieve the effect of buffering and shock absorption.

[0030] Furthermore, according to Figure 3 As shown, the flexible component 1 further includes an installation component, and the installation component is a snap ring 13;

[0031] The snap ring 13 is integrally installed on the outside of the connecting cylinder 12 for snap-fitting installation with the installation component 2;

[0032] Specifically, when the flexible component 1 and the installation component 2 are damaged, the snap ring 13 on the flexible component 1 can be separated from the installation component 2 to achieve the effect of disassembly and installation.

[0033] Even further, the specific disassembly and installation method is as follows; the installation component 2 includes an installation cylinder 21 and a snap-fitting component, and the snap-fitting component is a snap-fitting groove 23;

[0034] The snap-fitting groove 23 is inlaid on the inner side of the installation cylinder 21, and the inside is used for the snap-fitting work of the snap ring 13;

[0035] The middle of the snap ring 13 and the outer wall of the snap-fitting groove 23 are equiangularly distributed with screw grooves 5 penetrating through, and installation screws 4 are threadedly connected inside the screw grooves 5 for the installation work of the installation component 2 and the flexible component 1;

[0036] When installing, only need to snap the snap ring 13 on the connecting cylinder 12 with the snap-fitting groove 23 on the inner side of the installation cylinder 21, make the screw grooves 5 on the two correspond, take the installation screw 4, and make it rotate into the screw groove 5 to complete the installation work between the snap ring 13 and the installation cylinder 21, and then achieve the installation work between the installation component 2 and the flexible component 1. When disassembling, only need to take an external screwdriver to disassemble the installation screw 4 in the screw groove 5.

[0037] Specifically, according to Figures 3-4 as shown, the outer wall of the installation cylinder 21 is also penetrated with reserved grooves 22 at equal angles, and a threaded structure is arranged inside the reserved grooves 22 and is in threaded connection with the connection assembly 3.

[0038] The connection assembly 3 includes a threaded column 31 and a connection key 32. Threads are arranged on the outer wall of the threaded column 31 and are in threaded connection with the inside of the reserved groove 22. A connection key 32 is integrally installed at the bottom of the threaded column 31. The top end of the threaded column 31 is set as a polygonal structure and is engaged with the polygonal structure at the top end of the reserved groove 22;

[0039] Specifically, when the external fan shaft is engaged into the inside of the installation cylinder 21, at this time, it is necessary to rotate the polygonal structure at the top end of the threaded column 31 so that the threaded column 31 drives the connection key 32 at its bottom to descend and engage into the key groove inside the fan shaft, or directly extrude the outside of the fan shaft to complete the fixing work of the fan shaft;

[0040] The setting of the polygonal structure at the top end of the reserved groove 22 can facilitate the engagement of the polygonal structure at the top end of the threaded column 31 into its inside for storage, thereby making the outside of the entire connector more beautiful; Embodiment

[0041] In this application, according to Figure 5 as shown, the installation component and the engagement component can also be an installation groove 14 and an engagement block 24 respectively. Specifically, when installing and engaging, first, it is necessary to engage the installation groove 14 on the connection cylinder 12 with the engagement block 24 inside the installation cylinder 21 to complete the installation work of the connection cylinder 12 and the installation cylinder 21. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
