In the field of fluid machinery industry, a fluid pumping process is widely used, the problems of pipeline jumping, abrasion and the like mostly exist in the process of conveying fluid, particularly under the condition that the tail end of a pipeline is not fixed, the pipeline jumping is more severe, the abrasion is faster, and even in order to prevent the pipeline from jumping out of an attached tank body or other equipment, the pipeline needs to be manually fixed.

Chinese patent CN208845871U discloses a pipeline fixing device for trucks. Including couple seat and lock body, lock body one end with the couple seat is articulated, the other end pass through latched device with the couple seat is connected, the couple seat with the joint has rotatable internal fixation core between the lock body, internal fixation core will the couple seat with spatial separation between the lock body becomes a plurality of pipeline hole. As an improvement, a limiting block is fixed on the side wall of the inner fixed core, a hook inner groove matched with the limiting block is arranged on the inner wall of the hook seat, and a lock body inner groove matched with the limiting block is arranged on the inner wall of the lock body; when the hook seat is buckled with the lock body, the hook inner groove and the lock body inner groove form a circle, and when the internal fixing core rotates, the limiting block slides in the hook inner groove and the lock body inner groove. The lock catch mechanism comprises a hasp lock hinged on the lock body and a clamping frame hinged on the hasp lock, and a clamping block matched with the clamping frame is fixed on the hook seat; when the clamping frame is clamped on the clamping block, the clamping frame is driven to clamp the clamping block after the hasp lock passes through a critical angle, and the clamping enables the hasp lock and the clamping frame to be relatively static, so that locking is completed. And a positioning lug is fixed on the end face of one end of the hasp lock, which is arranged on the lock body, and a positioning groove matched with the positioning lug is arranged on the end face of one end, which is provided with the clamping block, of the hook seat. The positioning lug and the positioning groove can ensure that the hook inner groove is just connected with the lock body inner groove, so that the inner fixing core can rotate between the hook seat and the lock body without obstruction. The lock body is provided with a lock catch groove matched with the lock catch flank, and the lock catch flank can be buckled on the lock catch groove. And a hanging ring is fixed on the hook seat, and a retaining ring used for connecting a truck is connected to the hanging ring. One side of the retaining ring is hinged with a pressure lever through a torsion spring, and the pressure lever and the retaining ring form a closed annular structure. The inner fixing core equally divides the space between the hook seat and the lock body into three pipeline holes. The utility model has the advantages that: the inner fixing core is detachably connected with the hook seat, and the number of the fixable pipelines can be changed by replacing the inner fixing core, so that the plurality of pipelines are neatly fixed on the utility model; the pipeline is mostly rubbed with the inner fixed core, so that the service life of the hook seat can be prolonged by replacing the inner fixed core, and the cost is reduced; the inner fixing core can rotate between the hook seat and the lock body, and when the truck vibrates strongly, the inner fixing core drives the pipeline to rotate, so that the influence of the vibration on the pipeline can be relieved, and the service life of the pipeline is prolonged; the hasp lock can be opened repeatedly and close to safety and stability, the secondary locking has been accomplished to the block in hasp flank and hasp groove.

Although the pipeline fixing device has the advantages, the pipeline fixing device has the problems of complex structure, instability in fixing the hook and poor practicability.
