Abstract
The utility model provides a slot pipe fitting is with breaking bolt certainly, relates to connecting piece technical field, including the cylinder, and the one end rigid coupling of cylinder has the drive handle, has seted up the annular on the drive handle and has been from breaking the groove. The pipeline connecting structure solves the problems that in the pipeline connecting structure in the prior art, the connecting tightness between the pipeline connecting structure and the pipeline cannot be guaranteed in the connecting process, the pipeline is easy to slip when the pipeline connecting structure is too loose, the pipeline is extruded and deformed when the pipeline connecting structure is too tight, and torque measurement is required to be carried out on the pipeline connecting structure by torque measurement equipment, so that the pipeline connecting structure is inconvenient to use.
Description
Technical Field
The utility model relates to the technical field of connecting pieces, in particular to a self-breaking bolt for a groove pipe fitting.
Background
The clamp is a connecting device for connecting pipe fittings, valves and pipeline fittings with grooves and is used for tightening the quick connectors. The clamp connection mode has unique flexibility characteristics, so that the pipeline has the capabilities of resisting vibration, contraction and expansion, and compared with welding and flange connection, the stability of a pipeline system is improved, and the pipeline system is more suitable for temperature change, so that pipeline valves are protected, and the damage of pipeline stress to structural members is also reduced.
The prior art discloses a patent with publication number CN207729086U, which comprises an upper hoop shell, a lower hoop shell, a strap, a screw rod and a hoop tile, wherein the upper hoop shell and the lower hoop shell are fixedly held together from top to bottom, and the screw rod is screwed in a cavity formed by the upper hoop shell and the lower hoop shell.
The device gradually exposes the defects of the technology along with production and use, and is mainly shown in the following aspects:
the existing pipeline connecting structure cannot guarantee the tightness of connection between the pipeline and the pipeline in the connecting process, the phenomenon that the pipeline is prone to slipping is caused due to over looseness, the pipeline is extruded and deformed due to over tightness, the torque cannot be judged, torque measuring equipment is required to measure the pipeline, and the pipeline connecting structure is inconvenient to use.
In view of the above, the prior art is obviously inconvenient and disadvantageous in practical use, and needs to be improved.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model provides a self-breaking bolt for a groove pipe fitting, which is used for solving the problems that in a pipeline connecting structure in the traditional technology, the connecting tightness between the self-breaking bolt and a pipeline cannot be ensured in the connecting process, the self-breaking bolt easily slips when being too loose, the pipeline is extruded and deformed when being too tight, and torque measurement is required to be carried out on the self-breaking bolt by torque measurement equipment, so that the use is inconvenient.
In order to achieve the purpose, the utility model provides the following technical scheme:
the utility model provides a slot is self-breaking bolt for pipe fitting, includes the cylinder, the one end rigid coupling of cylinder has the drive handle, the annular is seted up on the drive handle and is self-broken the groove.
As an optimized scheme, an oval limiting plate is further fixedly connected between the driving handle and the end part of the column body.
As an optimized scheme, the distance between the opposite short sides of the oval limiting plate is the same as the diameter of the column.
In an advantageous embodiment, the axial length of the drive shaft section lying on the outside is greater than the length of the drive shaft section lying on the inside.
Preferably, the axial length of the annular self-breaking groove is greater than the length of the drive shank section located on the inside.
As an optimized scheme, the driving handle is a hexagonal prism.
As an optimized scheme, the outer wall of the cylinder body close to the other end is provided with external threads, and the external threads are connected with fastening nuts.
Compared with the prior art, the utility model has the beneficial effects that:
through the self-breaking bolt, when the pre-tightening force reaches a certain value, the driving handle section at the outer side is broken through the annular self-breaking groove, so that the pre-tightening force between the hoop and the groove pipe fitting can be conveniently mastered, and the operation is convenient;
the number of parts is small, the work is simple and convenient, and the failure rate is low; the structure is simple, and the service life is long; simple and convenient operation and control, easy large-scale manufacture and installation and wide application range.
