Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of spool, more particularly, it relates to a reinforced spool. BACKGROUND

[0002] In the field of mechanical transmission, the structural strength and angular positioning ability of the spool are the key factors to ensure the stability and service life of the equipment, however, the spools on the current market still have many technical defects in actual application, these problems not only affect the performance of the equipment, but also may cause safety hazards, which urgently need technical innovation and improvement.

[0003] The first problem is the insufficient structural strength, the spool in the prior art has significant defects: first, the traditional structure is prone to deformation at the stress concentration site after long-term bearing of tensile force and torque; second, the side plate may be damaged by fatigue during repeated stress, leading to bending or even breaking; third, the connection between the middle cylinder and the side plate has the risk of structural deformation when bearing a large load, such deformation not only causes the axial deviation of the spool, but also causes unstable operation, in addition, structural deformation may also cause accelerated wear of the bearing seat, further accelerating the aging of the equipment, the deficiencies of this traditional structure design not only significantly reduce the service life of the spool, but also may cause equipment operation failure, and even cause serious safety accidents.

[0004] More prominent is the lack of positioning function, the spool in the prior art has obvious problems, the spool cannot be accurately stopped at the required position during use due to the lack of positioning mechanism, after the operator rotates the spool to the ideal angle, the spool may continue to rotate under the action of its own weight or external force due to the lack of effective fixing device, during the cable winding and unwinding operation, the cable cannot be accurately positioned at the required length, such random rotation not only increases the operation difficulty, but also may cause the cable to be loose or too tight, the lack of positioning function may also cause the operation to be interrupted, and the position needs to be adjusted repeatedly, which seriously affects the work efficiency, the deficiencies of this design not only affect the operation accuracy and controllability of the equipment, but also significantly reduce the work efficiency and operation convenience.

[0005] The most critical is the insufficient reliability of the positioning structure, although some improved spools have added positioning function, the positioning mechanism has obvious defects, the simple positioning structure cannot provide sufficient locking force, especially under load working conditions, it is prone to failure, the positioning mechanism has limited bearing capacity, under the impact of external force, when the spool bears a large torque or vibration, the positioning device is prone to dislocation, causing the spool to continue to rotate for unintended winding and unwinding, the deficiencies of this structure design not only affect the use reliability and operation safety of the spool, but also greatly increase the maintenance frequency and use cost of the equipment.
