Description

a pipe clamp

technical field

The utility model is applied to the technical field of clamping pieces, in particular to a pipe clamping piece.

Background technique

Cylindrical workpieces are widely used in all walks of life, such as steel pipes, water pipes, air pipes, etc.; for commonly used bars, the easiest way is to use cable ties for binding, and the applicability of binding is directly determined by the material of the cable ties themselves. Usually nylon cable ties. Since the plastic head of the cable tie is engaged with the threaded structure of the cable tie, it is necessary to press the plastic head of the cable tie to untie the cable tie, which obviously brings great inconvenience. Most of the belts are one-time use, and are directly scrapped after being disassembled, which greatly increases the amount of consumables. In the ideal state, the cross-section of the cylindrical workpiece is circular, but the actual contour will have slight fluctuations, which may easily cause unstable clamping and overall shaking. The commonly used clamping mechanism on the market is the clamp table, which is a general fixture used to clamp the workpiece, and is also an essential tool in the fitter workshop. The clamp table is generally a one-piece casting, which has a large mass and is inconvenient to move. The workpiece and the clamp table are integrated into one structure, and the portability is too poor. Chinese patent CN102057201A discloses a clamp joint for clamping together coupling sleeves on pipes, which are connected at one end by two clamping rings through a hinge and can be opened around the hinge swivel between the position and the clamping position close to each other; and the clamping device on the end of the clamping ring opposite the hinge, the clamping bolt in the clamping device can be rotated from an active position to a The release position, which is folded out from the active position, in which the clamping bolts interact with the clamping ring in order to generate a clamping force which can press the clamping ring into the clamping position, which is achieved by a single clamping The overall structure of the workpiece is still not strong enough to be clamped by the device, and it is prone to loosening after a long time. At the same time, the opening angle of the clamping rings on both sides is limited, the operating space is too narrow, and it is difficult to be compatible with larger size workpieces, and there is no adjustable preload. Therefore, it is necessary to provide a pipeline clamp with simple structure, strong disassembly and good fastening effect.

Utility model content

The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a pipeline clamping piece with simple structure, strong disassembly and good fastening effect.

The technical scheme adopted by the present invention is as follows: the present invention comprises a first clamping ring piece and a second clamping ring piece, the ends of both sides of the first clamping ring piece are hinged with connecting rods, and the connecting rods The other end is provided with a threaded structure, the middle parts of both sides of the second clamping ring are provided with a first through groove matching the connecting rod, the threaded structure is threadedly fitted with a nut, and the nut is located at the The outer edge side of the first through groove and the outer diameter of the nut is greater than the height of the first through groove, when the first clamping ring is clamped with the second clamping ring, the first clamping ring is clamped. The inner side of the first clamping ring and the inner side of the second clamping ring are combined to form a space suitable for the product.

It can be seen from the above solution that the inner side of the first clamping ring and the inner side of the second clamping ring are combined to form a space suitable for the product, which is suitable for clamping standard pipes. The ring piece is connected and fixed with the second clamping ring piece through the threaded cooperation of the nut and the threaded structure. Before clamping, the first clamping ring piece and the second clamping ring piece are integral structures. , so loosen the nut, so that the first clamping ring part is separated from the second clamping ring part, and the first clamping ring part and the second clamping ring part are sleeved together on the pipeline product The outer side of the connecting rod rotates into the first through groove, and according to the size of the pipe product, the nut is twisted and engaged with the threaded structure, and the depth of the nut engaging the threaded structure is adjusted. The outer diameter of the nut is larger than the height of the first through groove, so the nut is clamped on the outer edge side of the first through groove, and the connecting rod is limited and fixed in the first through groove, The first clamping ring piece and the second clamping ring piece are fastened together to ensure the stability of the pipeline product. After the nut is fixed at one end of the second clamping ring piece, Then fix the end adjustment on the other side, so as to meet the installation requirements. Compared with a single clamping structure, the pipe clamp has a better tightening effect, and can be quickly disassembled and assembled, and can be reused. Cable ties are more practical.

A preferred solution is that the pipe clamping member further includes a pin, an escape groove is provided at the top of the arc inside the first clamping ring, and the pin passes through the first clamping ring to the In the avoidance groove, the end of the pin is provided with the superior glue.

It can be seen from the above solution that the pin passes through the first clamping ring into the avoidance groove, and when the first clamping ring and the second clamping ring are in position limit fit, tighten the The column pin enables the top-press fit of the superior glue and the pipeline product, which can reduce the damage to the surface of the pipeline product on the one hand, and can ensure the clamping of the pipeline product on the other hand to achieve the secondary positioning effect.

A preferred solution is that the pipe clamping member further includes two rotating shafts, the middle of both sides of the first clamping ring member is provided with a second through groove, and the two rotating shafts respectively pass through the first clamping ring in sequence. The upper end of a clamping ring, the second through groove and the lower end of the first clamping ring, and the end of the connecting rod away from the threaded structure rotates around the rotating shaft.

It can be seen from the above solution that one end of the connecting rod is hinged in the second through groove through the rotating shaft, and the connecting rod can rotate laterally around the rotating shaft, so that the connecting rod rotates to the desired position. The first through groove is convenient for clamping and fixing.

A preferred solution is that a plurality of positioning holes are provided on the outer side of the first clamping ring member, and the plurality of positioning holes are limitedly matched with an external positioning mechanism.

It can be seen from the above solution that the first clamping ring can be fixed to other external positioning mechanisms through a plurality of the positioning holes, so as to realize the standardization and universality of the workpiece.

A preferred solution is that the nut includes a wing nut.

It can be seen from the above solution that the nut adopts a butterfly nut structure, which is more convenient for fixing or loosening by hand, and does not require special tools to screw the screw, which is beneficial to improve work efficiency.
