Description

Clamp connection structure

Technical Field

The utility model relates to a connection structure, especially a clamp connection structure.

Background

The clamp is widely applied to the fixed connection of cables and pipelines. For some relatively low durometer hoses, the clamp is often formed by bending a thin sheet of material to form a structure that is secured by a mating fastener. The clamp structure has the characteristics of good ductility and uniform stress; for some high-pressure pipelines with higher hardness, the clamp formed by bending the sheet metal plate is difficult to clamp by manually tightening. Stainless steel band clamps are commonly used, but the size envelope of the structure is large, and the operation is difficult in a limited structural space.

Disclosure of Invention

The utility model discloses the purpose:

the utility model discloses a to above-mentioned technical situation, and design a clamp connection structure for high-pressure line. The purpose is on the premise of satisfying the pipeline fastening and sealing, and the structure principle is simple, the envelope is small, and the locking and fixing are reliable.

The utility model discloses technical scheme:

a clamp connection structure is characterized by comprising a clamping ring, a clamping block and a screw; the screw is screwed into the clamping ring through a thread section on the clamping ring, a polished rod at the lower end of the screw is sleeved into the clamping block, and the clamping block comprises an upper end 7 of the clamping block and a circular section 8 at the lower end of the clamping block.

The clamping ring comprises a clamping ring upper end 4 and a clamping ring lower end circular section 9; the side walls of two ends of the upper end 4 of the clamping ring are provided with clamping ring safety holes 5;

the screw comprises a screw head 2, a screw thread section 3 and a screw polish rod 6; the center line position of the adjacent surface of the screw head 2 is provided with a screw safety hole 1, and the screw head 2, the screw thread section 3 and the screw polish rod 6 are arranged from top to bottom in sequence.

The diameters of the circular section 9 at the lower end of the clamping ring and the circular section 8 at the lower end of the clamping block are slightly smaller than the diameter of the pipeline 10.

The screw polish rod 6 is movably connected with the upper end 7 of the clamping block.

The thickness of the band is determined by the diameter of the screw.

The screw head 2 can be designed into different shapes according to different tools.

The utility model has the advantages that: the utility model discloses can realize the fixed chucking of some high-pressure pipelines. The structure principle is simple, the dismounting is convenient, and the number of components is small. The installation is the spare part state before, and the installation can lock reliably afterwards.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

referring to fig. 1-3 and fig. 1-2, the clamp structure comprises a clamp ring, a clamp block and a screw. Wherein the snap ring consists of a snap ring upper end 4, a snap ring lower end circular section 9 and a snap ring safety hole 5; the fixture block consists of a fixture block upper end 7 and a fixture block lower end circular section 8; the screw consists of a screw head 2, a screw safety hole 1, a screw thread section 3 and a screw polish rod 6. The pipeline 10 is sleeved in the circular section 9 at the lower end of the snap ring in advance, and the pipeline 10 is extruded and deformed because the diameter of the circular section 9 is slightly smaller than that of the pipeline 10.

The screw thread section 3 is screwed into the upper end 4 of the clamping ring, and the screw polish rod 6 is sleeved into the upper end 7 of the clamping block. As shown in fig. 3, the screw head 2 may be designed into a straight slot or a hexagon head, a semi-circular head, etc. according to the operating tool. Along with the screw in, the screw drives fixture block upper end 7 and moves down, and fixture block lower extreme circle cross-section 8 contacts pipeline 10, continues to revolve the screw, and according to the compressive capacity of pipeline, fixture block upper end 7 compresses pipeline 10 to appointed thickness, designs the screw into that screwhead 2 just flushes with snap ring upper end 4 this moment, shows to target in place promptly. The fuse 11 passes through the snap ring fuse hole 5 and the screw fuse hole 1, and plays a role in preventing looseness.

During disassembly and assembly, the fuse 11 is loosened, the screw head 2 is moved, the screw polish rod 6 is screwed out to the upper part of the upper end 7 of the clamping block, and the clamping block 7 can be manually taken out. Finally, the broken card is drawn out from the pipeline 10 to realize the disassembly.

Because this scheme is applicable to the great high-pressure line of hardness, snap ring lower extreme circle cross-section 9 and fixture block lower extreme circle cross-section 8 diameter should slightly be less than pipeline 10 diameter, both can guarantee that pipeline 10 all directions can the compression deformation, can not cause the installation difficulty again. The screw polish rod 6 is movably connected with the upper end 7 of the clamping block, so that the clamping block can be replaced at any time. By measuring the distance the screw is screwed in, the amount of compression of the pipeline 10 can be calculated, which in turn ensures that the pipeline 10 is sufficiently compressed without being crushed. The thickness of the clamp is determined by the diameter of the screw, and only the height of the screw head 2 needs to be ensured after the installation is finished, so that the requirement of small envelope is met. The screw head 2 can be designed into different shapes according to different tools, so that the requirement of convenient disassembly and assembly is met. The whole clamp has no complex parts, the processing technology is simple, the tightening force can be realized by screwing up the clamp through threads, and the locking is reliable.
