Description

Technical Field

[0001] The utility model relates to the technical field of abrasive belt machines, in particular to a quick disassembly and assembly structure of an abrasive belt head. Background Art

[0002] In the prior art, the connection method between the sanding belt head assembly and the angle grinding assembly of the belt sander is usually screw connection, which requires the use of multiple screws for fixing. However, since there are many models of angle grinding assemblies, a belt sander must be used with multiple angle grinding assemblies, which requires frequent disassembly and assembly of the angle grinding assemblies. However, disassembly and assembly of multiple screws is relatively time-consuming and laborious. A quick-release clamp is commonly used on circular pipe fittings such as bicycle seat tubes, handlebar tubes, and pipes. Its structure generally includes an elastic clamp, a cam wrench, a screw, and a nut. The clamp is C-shaped and has a notch. The screw passes through the notch of the clamp. One end of the screw is connected to the nut, and the other end is connected to the cam wrench through a rotating shaft. The end of the cam wrench connected to the screw is an eccentric wheel. After the cam wrench is bent by hand, the clamp can be clamped or loosened through the contact and separation of the eccentric wheel and the clamp, which is relatively convenient to operate. The clamp disclosed in CN214985852U scooter folding device, such as the clamp disclosed in CN220470387U a ruler locking mechanism.

[0003] Therefore, if the above clamp structure is applied to the sanding machine, the disassembly and assembly efficiency of the sanding head assembly and the angle grinding assembly can be improved, and the disassembly and assembly speed can be increased. Therefore, how to develop a sanding head quick disassembly and assembly structure is the research direction that the staff in this field want to study. Utility Model Content

[0004] In view of the above-mentioned defects of the prior art, the purpose of the utility model is to provide a structure for quickly disassembling and assembling a sanding belt head.

[0005] The technical solution of the utility model is: a sanding belt head quick disassembly and assembly structure, comprising a sanding belt head assembly and an angle grinding assembly, a quick-release clamp is installed at the lower end of the sanding belt head assembly, the rear end of the angle grinding assembly has a round head, and the quick-release clamp clamps the round head; the quick-release clamp comprises an elastic clamp fixed to the lower end of the sanding belt head assembly and clamped outside the round head, a bolt installed at the left end of the elastic clamp, and a wrench rotatably connected to the bolt and used to control the elastic clamp to clamp or loosen the round head.

[0006] Furthermore, the left end of the elastic clamp has a first clamp block and a second clamp block distributed vertically, an opening is formed between the first clamp block and the second clamp block, the bolt extends vertically through the first clamp block and the second clamp block, and the lower end of the bolt is threadedly connected with a nut abutting against the bottom of the second clamp block.

[0007] Furthermore, a gasket is placed on the top of the first clamp block, and the bolt passes through the gasket. One end of the wrench has a cam, which is rotatably connected to the upper end of the bolt through a rotating shaft, and the cam is pressed on the top of the gasket.

[0008] The application of the sand belt head quick disassembly and assembly structure provided by the utility model has the beneficial effect that the angle grinding assembly can be clamped and loosened by turning a wrench by hand, thereby improving the disassembly and assembly efficiency.

[0012] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model:

[0013] like Figure 1 , Figure 2 As shown, a quick disassembly structure of a sanding belt head includes a sanding belt head assembly 1 and an angle grinding assembly 2. A quick release clamp 3 is installed at the lower end of the sanding belt head assembly 1. The rear end of the angle grinding assembly 2 has a round head 21, and the quick release clamp 3 clamps the round head 21; the quick release clamp 3 includes an elastic clamp 31 fixed to the lower end of the sanding belt head assembly 1 and clamped outside the round head 21, a bolt 32 installed at the left end of the elastic clamp 31, and a wrench 33 rotatably connected to the bolt 32 and used to control the elastic clamp 31 to clamp or loosen the round head 21.

[0014] like Figure 2As shown, the left end of the elastic clamp 31 has a first clamp block 311 and a second clamp block 312 distributed up and down, an opening 313 is formed between the first clamp block 311 and the second clamp block 312, and a bolt 32 extends up and down through the first clamp block 311 and the second clamp block 312, and the lower end of the bolt 32 is threadedly connected with a nut 34 that rests against the bottom of the second clamp block 312. A gasket 35 is placed on the top of the first clamp block 311, and the bolt 32 passes through the gasket 35. One end of the wrench 33 has a cam 331, and the cam 331 is rotatably connected to the upper end of the bolt 32 through a rotating shaft 36, and the cam 331 is pressed on the top of the gasket 35.

It contacts the gasket 35 through different parts of it, can provide different pressures to the gasket 35, can change the size of the opening 313, and can make the elastic clamp 31 product deform when the wrench 33 is opened or closed. Figure 1 When the angle grinding assembly 2 is removed from the state, the wrench 33 is first opened to make the elastic clamp 31 loosen the round head 21 of the angle grinding assembly 2, and then the angle grinding assembly 2 can be removed.

[0015] The utility model provides a quick disassembly structure for a sanding belt head, which can realize the clamping and loosening of the angle grinding assembly 2 by turning the wrench 33 by hand, thereby improving the disassembly efficiency.
