Description

Technical Field

[0001] The invention relates to a vibration reduction device, more specifically, to a vibration reduction device for a driving shaft of a mixer. Background Art

[0002] A mixer usually uses a motor to drive a stirring rod. The stirring blades on the stirring rod rotate continuously to stir the fluid or solid inside the mixing machine to achieve a uniform mixing effect. During stirring, the drive shaft on the motor will be subjected to a horizontal force, thereby generating horizontal vibrations. These vibrations will damage the drive shaft and the motor. In order to avoid deformation of the drive shaft or damage to the motor caused by vibration, a shock absorbing device is often required when the mixer is in use. In addition, the existing shock absorbing device has a complex structure, is expensive, and cannot be easily disassembled. Therefore, maintenance and repair are relatively difficult and the service life is short. Summary of the invention

[0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a shock absorbing device for a mixer transmission shaft, which has the advantages of simple structure, low cost, obvious effect, easy disassembly and good stability.

[0004] The above technical problems of the present invention are mainly solved by the following technical solutions:

[0005] A shock absorbing device for a mixer drive shaft, the shock absorbing device for the mixer drive shaft comprising a holder and a connecting seat, a connecting hole is provided in the middle of the connecting seat, slots are provided at both ends of the connecting seat, holder bolts are provided on both sides of the holder, a connecting hole is provided on the surface of the holder bolt, a spring is connected to the connecting hole, and a protrusion is provided inside the holder.

[0006] As a preferred embodiment of the present invention, the connecting seat is snap-connected with the protrusion inside the socket through the slots at both ends thereof.

[0007] As a preferred embodiment of the present invention, the clamping seat is movably connected to the spring through the clamping seat bolts and the clamping holes on both sides thereof.

[0008] As a preferred embodiment of the present invention, the outer surface of the card seat is an arc-shaped structure, the inner side of the card seat is a square structure and is engaged with both ends of the connecting seat.

[0009] As a preferred embodiment of the present invention, the springs are symmetrically installed on both sides of the holder.

[0010] The supporting device of the present invention has the following advantages: when in use, one end of the connecting seat is embedded with the inner side of the clamping seat. At this time, the connecting seat clamps the protrusions through the clamping grooves at both ends of the connecting seat, so that the connecting seat can be effectively fixed and will not fall off. Then one end of the spring is connected to the clamping seat bolt through the clamping hole. After the connection of one end is completed, the spring is pulled to connect it to the clamping seat at the other end of the connecting seat through the clamping seat bolt and the clamping hole. After the connection is completed, the spring is always in a stretched state, and the connecting seat and the clamping seat can be connected to make the device structure tighter and more integrated. After the connection is completed, the mixer drive shaft is passed through the connecting hole in the middle of the connecting seat. When the mixer drive shaft is working, the horizontal vibration generated by its rotation and shaking can be fully offset by the spring, thereby realizing the shock absorption function. The structure is simple, the cost is low, the stability is good, the spring and the clamping seat bolt are movably connected, the connection is flexible, it is easy to install and disassemble, and it is practical.

[0018] The present invention is further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0019] like Figures 1 to 5As shown, a shock absorbing device for a mixer drive shaft, the shock absorbing device 1 for the mixer drive shaft comprises a base 2 and a connecting base 6, a connecting hole 5 is provided in the middle of the connecting base 6, a clamping groove 9 is provided at both ends of the connecting base 6, a base bolt 4 is provided on both sides of the base 2, a clamping hole 7 is provided on the surface of the base bolt 4, a spring 3 is connected to the clamping hole 7, and a protrusion 8 is provided inside the base 2.

[0020] The connecting base 6 is engaged with the protrusion 8 inside the base 2 through the card slots 9 at both ends thereof.

[0021] The holder 2 is movably connected to the spring 3 via the holder bolts 4 and the engaging holes 7 on both sides thereof.

[0022] The outer surface of the card holder 2 is in an arc-shaped structure, and the inner side of the card holder 2 is in a square structure and is engaged with the two ends of the connecting seat 6.

[0023] The springs 3 are symmetrically mounted on both sides of the holder 2 .

[0024] When in use, one end of the connecting seat 6 is embedded with the inner side of the holder 2. At this time, the connecting seat 6 engages the protrusion 8 through the grooves 9 at both ends of the connecting seat 6, so that the connecting seat 6 can be effectively fixed and will not fall off. Then one end of the spring 3 is connected to the holder bolt 4 through the engaging hole 7. After one end is connected, pull the spring 3 to connect it to the holder 2 at the other end of the connecting seat 6 through the holder bolt 4 and the engaging hole 7. After the connection is completed, the spring 3 is always in a stretched state. Similarly, the spring 3 is installed on the other side of the holder 2 using the same steps, so that the spring 3 is located on both sides of the connecting seat 6. After the connection is completed, the mixer drive shaft is passed through the connecting hole 5 in the middle of the connecting seat 6. When the mixer drive shaft is working, the horizontal vibration caused by its rotation and shaking can be fully offset by the spring 3, thereby achieving a shock absorbing effect.

[0025] The device has a simple structure, obvious effect, convenient disassembly and good stability.
