Description

Technical Field

[0001] The utility model relates to the technical field of armoring, in particular to a locking structure and a steel strip armoring machine. Background Art

[0002] Armoring refers to adding a metal protective layer to the outside of the product to protect the internal structure from damage.

[0003] In the existing technology, armoring is a common process in industrial production. A metal protective layer is wrapped around the outer surface of an object to enhance the object's protection and strength. A steel strip armoring machine is a common armoring machine that wraps the steel strip around the surface of the back armored object by rotating.

[0004] However, when the steel strip armoring machine stops armoring, since the steel strip is stored on the winding roller and the steel strip is pulled by the moving object and wrapped around the object, when the armoring stops, the winding roller will continue to unwind due to inertia and cannot stop in time. Utility Model Content

[0005] The purpose of the present utility model is to provide a locking structure and a steel strip armoring machine to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a locking structure, comprising:

[0007] An armoring machine body, wherein an armored object is arranged inside the armoring machine body, a motor is fixed to the upper surface of the armoring machine body, a transmission belt is provided on the movable sleeve of the motor output end, a fixed shaft is fixed to the side surface of the armoring machine body, and a reel roller is provided on the outer surface of the fixed shaft;

[0008] A storage shell is provided with an inner groove inside the storage shell, a guide rod is provided inside the inner groove, the guide rod passes through the storage shell, a limit plate is fixed to the end of the guide rod, the limit plate is located outside the storage shell, and a transmission disk is movably provided at the port of the storage shell.

[0009] Preferably, a tooth groove is provided on the outer surface of the unwinding roller on the side close to the armoring machine body, and the storage shell is fixed on the outer surface of the fixed shaft between the unwinding roller and the armoring machine body. A through hole is provided on the outer surface of the storage shell, and the through hole is connected to the inner groove.

[0010] Preferably, an annular groove is opened on the inner wall of the inner groove near the port, a tooth block is fixed on the lower surface of the limit plate, the tooth block corresponds to the tooth groove, and a transmission rod is fixed on the outer surface of the lower end of the guide rod.

[0011] Preferably, an annular block is fixed on the arcuate surface of the transmission disc, and the annular block corresponds to and is clamped in the annular groove, and the two are movably connected.

[0012] Preferably, a connecting ring is fixed on the outer surface of the transmission disc, and the connecting ring is movably sleeved on the outer surface of the fixed shaft. An arc groove is opened on the outer surface of the transmission disc.

[0013] Preferably, the transmission rod corresponds to and is locked in the arc-shaped groove, and the two are movably connected.

[0014] A steel strip armoring machine comprises the locking structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The motor drives the transmission disc to rotate through the transmission belt. Due to the existence of the arc groove, the rotation of the transmission disc will change the position of the transmission rod in the arc groove, and the lower end of the arc groove is closer to the axis center. Therefore, when the transmission rod is at the lower end of the arc groove, it will drive the guide rod to move toward the axis center. At the same time, the guide rod will drive the limit plate to move toward the axis center, so that the tooth block is stuck in the tooth groove. Since the storage shell is fixed to the fixed shaft, the guide rod inserted in the storage shell will not rotate. Therefore, the unwinding roller cannot rotate on the fixed shaft under the restriction of the tooth block and the tooth groove. The unwinding roller cannot rotate and the steel belt stored on its surface will not be unwound due to inertia, thereby achieving the locking of the unwinding roller.

DETAILED DESCRIPTION

[0023] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clearly understood, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figures 1 to 5 The utility model provides a technical solution: a locking structure, an armored object 4 is provided inside the armoring machine body 1, a motor 5 is fixed on the upper surface of the armoring machine body 1, a transmission belt 10 is provided on the movable sleeve of the output end of the motor 5, and the motor 5 drives the transmission disk 9 to rotate through the transmission belt 10, a fixed shaft 2 is fixed on the side surface of the armoring machine body 1, and a reeling roller 3 is provided on the movable sleeve of the outer surface of the fixed shaft 2, and the reeling roller 3 is a storage support for the steel belt.

[0025] An inner groove 12 is provided inside the storage shell 7, and a guide rod 16 is provided inside the inner groove 12. The guide rod 16 passes through the storage shell 7, and a limit plate 8 is fixed to the end of the guide rod 16. The limit plate 8 is located outside the storage shell 7, and a transmission disk 9 is movably provided at the end of the storage shell 7. Since the storage shell 7 is fixed to the fixed shaft 2, the guide rod 16 inserted in the storage shell 7 will not rotate. Therefore, the unwinding roller 3 cannot rotate on the fixed shaft 2 under the restriction of the tooth block 14 and the tooth groove 6. The unwinding roller 3 cannot rotate and the steel belt stored on its surface will not be unwound due to inertia, thereby realizing the locking of the unwinding roller 3.

[0026] On the basis of Example 1, in order to achieve the locking of the unwinding roller 3, a tooth groove 6 is provided on the outer surface of the unwinding roller 3 on the side of the armoring machine body 1, and the storage shell 7 is fixed to the outer surface of the fixed shaft 2 between the unwinding roller 3 and the armoring machine body 1. Since the storage shell 7 is fixed to the fixed shaft 2, the guide rod 16 inserted in the storage shell 7 will not rotate, and a through hole 11 is provided on the outer surface of the storage shell 7, which is connected to the inner groove 12.

[0027] An annular groove 13 is provided on the inner wall of the inner groove 12 near the port, and a tooth block 14 is fixed to the lower surface of the limit plate 8. The tooth block 14 corresponds to the tooth groove 6. The unwinding roller 3 cannot rotate on the fixed shaft 2 under the restriction of the tooth block 14 and the tooth groove 6. A transmission rod 15 is fixed to the outer surface of the lower end of the guide rod 16.

[0028] An annular block 19 is fixed to the arcuate surface of the transmission disc 9, and the annular block 19 corresponds to and is locked in the annular groove 13, and the two are movably connected, so that the transmission disc 9 and the storage shell 7 are movably connected, and the transmission disc 9 will not separate from the storage shell 7.

[0029] A connecting ring 18 is fixed to the outer surface of the transmission disc 9, and the connecting ring 18 is movably sleeved on the outer surface of the fixed shaft 2. One end of the transmission belt 10 is sleeved on the output end of the motor 5, and the other end is sleeved on the surface of the connecting ring 18, thereby driving the transmission disc 9 to rotate. An arc groove 17 is opened on the outer surface of the transmission disc 9.

[0030] The transmission rod 15 corresponds to and is clamped in the arc groove 17, and the two are movably connected. Due to the existence of the arc groove 17, the rotation of the transmission plate 9 will change the position of the transmission rod 15 in the arc groove 17, and the lower end of the arc groove 17 is closer to the axis position, so when the transmission rod 15 is located at the lower end of the arc groove 17, it will drive the guide rod 16 to move toward the axis direction.

[0031] The specific solution is as follows: when the armoring machine body 1 stops running, the motor 5 will be started, and the motor 5 will drive the transmission disc 9 to rotate through the transmission belt 10. Due to the existence of the arc groove 17, the rotation of the transmission disc 9 will change the position of the transmission rod 15 in the arc groove 17, and the lower end of the arc groove 17 is closer to the axis position, so when the transmission rod 15 is located at the lower end of the arc groove 17, it will drive the guide rod 16 to move toward the axis, and at the same time, the guide rod 16 will drive the limit plate 8 to move toward the axis, so that the tooth block 14 is stuck in the tooth groove 6. Since the storage shell 7 is fixed to the fixed shaft 2, the guide rod 16 inserted in the storage shell 7 will not rotate. Therefore, the unwinding roller 3 cannot rotate on the fixed shaft 2 under the restriction of the tooth block 14 and the tooth groove 6. The unwinding roller 3 cannot rotate and the steel strip stored on its surface will not be unwound due to inertia, thereby achieving the locking of the unwinding roller 3.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
