[0003] The connection method between the traditional abrasive disc and the fixing rod often has the problem of insufficient connection tightness, which may cause the abrasive disc and the fixing rod to become loose or even fall off during high-speed rotation or long-term use, thus affecting work efficiency and safety. At the same time, the connection method between the traditional abrasive disc and the fixing rod is usually relatively complex and requires the use of special tools or equipment for installation, which not only increases the installation difficulty, but also may cause human errors during the installation process, further affecting the connection tightness and stability. Therefore, a quick-clamping and anti-dropping abrasive disc is hereby proposed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a quick-clamping and anti-dropping abrasive disc, which solves the problem that the connection method between the traditional abrasive disc and the fixing rod in the prior art often has insufficient connection tightness, which may cause the abrasive disc and the fixing rod to become loose or even fall off during high-speed rotation or long-term use, thus affecting work efficiency and safety. At the same time, the connection method between the traditional abrasive disc and the fixing rod is usually relatively complex and requires the use of special tools or equipment for installation, which not only increases the installation difficulty, but also may cause human errors during the installation process, further affecting the connection tightness and stability.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A quick-clamping and anti-dropping abrasive disc includes a circular ring. A plurality of impeller blades are fixedly connected to the outer ring of the circular ring. A fixing rod is vertically arranged in the inner cavity of the circular ring. Slots are opened on both sides of the inner ring of the circular ring.

When the insertion blocks are aligned with the corresponding slots inside the circular ring, the user releases the limiting blocks. Under the action of the springs, the limiting blocks return to their initial positions, and the insertion blocks also smoothly enter the inner cavities of the slots, thus achieving the docking of the fixed rod and the impeller. Finally, the user passes a bolt through the corresponding through hole and threadedly engages it with the adjacent screw hole to strengthen the connection between the two.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] Refer to Figures 1-5 , a quick-clamping and anti-dropping abrasive disc, including a circular ring 3, the outer ring of the circular ring 3 is fixedly connected with a plurality of impeller blades 2, the inner cavity of the circular ring 3 is vertically provided with a fixing rod 1, both sides of the inner ring of the circular ring 3 are provided with slots 12, both sides of the outer ring of the fixing rod 1 are fixedly connected with fixing boxes 5, one side of the inner cavity of the fixing box 5 is fixedly connected with a damping rod 8, one end of the damping rod 8 is fixedly connected with a limiting block 6, one side of the limiting block 6 is fixedly connected with an insertion block 9, and a screw hole 10 is opened at the top of the insertion block 9. Specifically, when in use, the user can first pull the two limiting blocks 6, so that the limiting blocks 6 squeeze the adjacent damping rods 8 and springs 7, so that the limiting blocks 6 can smoothly enter the inner cavity of the circular ring 3. When the insertion block 9 is aligned with the corresponding slot 12 inside the circular ring 3, the user releases the limiting block 6. Under the action of the spring 7, the limiting block 6 will move out of the initial position, so that the insertion block 9 also smoothly enters the inner cavity of the slot 12, thereby achieving the docking of the fixing rod 1 and the impeller. Finally, the user uses a bolt to pass through the corresponding through hole 4 and thread it with the adjacent screw hole 10 to strengthen the connection between the two. Through the structural design, the connection between the fixing rod 1 and the abrasive disc is made more compact. At the same time, the connection method of the two is more convenient for the user to operate and connect, simplifies the convenient installation steps of the user, brings convenience to the actual users, and reduces the work burden of the users.

[0025] This solution has the following working process:

[0026] When in use, personnel can first pull the two limit blocks 6 so that the limit blocks 6 squeeze the adjacent damping rod 8 and spring 7, so that the limit blocks 6 can smoothly enter the inner cavity of the ring 3. When the plug block 9 is aligned with the corresponding slot 12 inside the ring 3, the personnel release the limit block 6. Under the action of the spring 7, the limit block 6 will move out of the initial position, so that the plug block 9 can smoothly enter the inner cavity of the slot 12, thereby achieving the docking of the fixing rod 1 and the impeller. Finally, the personnel use bolts to pass through the corresponding through holes 4 to screw them together with the adjacent screw holes 10 to strengthen the connection between the two.

[0027] According to the above working process, we can know that:

[0028] Through the structural design, the connection between the fixed rod 1 and the flap wheel is made tighter. At the same time, the connection method between the two is more convenient for personnel to operate and connect, which simplifies the convenient installation steps for personnel, brings convenience to actual users, and reduces the workload of personnel.

[0029] Furthermore, a spring 7 is installed on the outer ring of the damping rod 8, one end of the spring 7 is fixedly connected to the inner wall of one side of the adjacent fixing box 5, and the other end of the spring 7 is fixedly connected to one side of the adjacent limit block 6. Specifically, through the setting of the spring 7, the damping rod 8 has the ability to return to the initial position.

[0030] Furthermore, one end of the plug block 9 is plugged into the adjacent slot 12 . Specifically, by setting the slot 12 and cooperating with the plug block 9 , the fixing rod 1 can be tightly connected to the ring 3 .

[0031] Furthermore, the top and the bottom of the limit block 6 are fixedly connected with a paddle 11. Specifically, the setting of the paddle 11 makes it convenient for people to pull the limit block 6.

[0032] Furthermore, two through holes 4 are provided at both ends of the ring 3, and a bolt is provided on one side of the through hole 4. One end of the bolt passes through the adjacent through hole 4 and is screwed together with the corresponding screw hole 10 by means of a thread. Specifically, through the provision of the through hole 4, the bolt can connect the adjacent plug blocks 9 and the ring 3.

[0033] Furthermore, the two fixing boxes 5 are symmetrically distributed on both sides of the outer circle of the fixing rod 1 . Specifically, through the arrangement of the fixing boxes 5 , a storage space is provided for the corresponding damping rods 8 .

[0034] In summary: When in use, the user can first pull the two limit blocks 6, so that the limit blocks 6 squeeze the adjacent damping rods 8 and springs 7, enabling the limit blocks 6 to smoothly enter the inner cavity of the ring 3. When the insertion block 9 aligns with the corresponding slot 12 inside the ring 3, the user releases the limit blocks 6. Under the action of the spring 7, the limit blocks 6 return to their initial positions, and thus the insertion block 9 also smoothly enters the inner cavity of the slot 12, thereby achieving the docking of the fixed rod 1 and the impeller. Finally, the user passes a bolt through the corresponding through hole 4 and threads it into the adjacent screw hole 10 to reinforce the connection between the two. Through the setting of the spring 7, the damping rod 8 has the ability to return to its initial position. Through the setting of the slot 12, in cooperation with the insertion block 9, the fixed rod 1 can be tightly connected to the ring 3. Through the setting of the dial 11, it is convenient for the user to pull the limit block 6. Through the setting of the through hole 4, the bolt can connect the adjacent insertion block 9 and the ring 3. Through the setting of the fixed box 5, a storage space is provided for the corresponding damping rod 8. Through the structural design, the connection between the fixed rod 1 and the impeller is made more tight. At the same time, the connection method between the two is more convenient for the user to operate and connect, simplifying the convenient installation steps for the user, bringing convenience to the actual users, and reducing the work burden of the users.
