Description

Technical Field

[0001] This utility model relates to the field of cable tie machine technology, specifically a handheld automatic cable tie machine. Background Technology

[0002] As an electric strapping tool, the power connection method of a handheld automatic cable tie machine directly affects its ease of use. Currently, most similar products on the market adopt a power cord integrated with the machine body.

[0003] As disclosed in the patent announcement CN214112967U, a handheld automatic cable tie machine includes a body. One end of the body is equipped with a gas feeding pipe through which cable ties are blown by gas via a square rubber tube, and the other end of the body is equipped with an automatic cable tie mechanism. The beneficial effects of this invention are as follows: Cable ties are automatically dispensed by a vibrating disc and then conveyed to the gas feeding pipe via a square rubber tube. From there, they are transported to the automatic cable tie mechanism at the other end of the body, completing the automatic cable tie operation. The structure and layout of electrical components are reasonable, and the logical relationship between the structure and control is also reasonable, achieving the effect of small size and high working efficiency.

[0004] While the aforementioned patent achieves the advantages of small size and high working efficiency, the integrated structure of the power cord and the main body means that when the power cord is damaged, the entire device needs to be replaced or professionally repaired, which significantly increases the cost of use and affects work efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] A handheld automatic cable tie machine includes a gun-type cable tie machine body 1, with a power terminal 2 fixedly connected to its left end. A sealing ring 8 is arranged in annular shape on the inner wall of the right side of the power terminal 2. Three power sockets 18 are arranged in a triangle on the left side of the power terminal 2. The right end of the power connector 3 is inserted into the power socket 18. The power connector 3 is detachably connected to the end of the power terminal 2 away from the gun-type cable tie machine body 1. A disassembly and assembly mechanism is provided between the power terminal 2 and the power connector 3. The disassembly and assembly mechanism includes a movable groove 5. The movable groove 5 is provided through the upper and lower ends of the power terminal 2. The elastic clip 6 is fixedly connected to the upper and lower ends of the right side of the power connector 3. A triangular block 7 is fixedly connected to the upper right side of the elastic clip 6. When the power connector 3 is inserted into the power terminal 2, the left end face of the triangular block 7 elastically abuts against the left end face of the movable groove 5.

[0026] In this embodiment, the power connector 3 can be quickly plugged in and unplugged through the cooperative design of the elastic clip 6 and the movable slot 5, which solves the problem of inconvenient disassembly of the integrated connection in the prior art, facilitates the individual replacement of the power cord 4 or the connector, and reduces maintenance costs.

[0027] like Figure 3 and Figure 4As shown, a power connector 3 is fixedly connected to a power cord 4 at the end furthest from the power receiving end 2. An anti-breakage mechanism is provided between the power receiving end 2 and the power cord 4. The anti-breakage mechanism includes a rubber block 9. Rubber blocks 9 are fixedly connected to the upper and lower ends of the right side of the power cord 4. A hole 10 is provided at the end of rubber block 9 closest to the power cord 4. Side blocks 11 are connected to the upper and lower ends of the left outer side of the power receiving end 2. A second rubber block 19 is fixedly connected to the outer side of the side blocks 11. A second hole 12 is provided in the middle of the second rubber block 19. A gap is provided between the second hole 12 and the first hole 10. Pull strap 13, the left side of pull strap 13 is fixedly sleeved with hole 10, and the right side of pull strap 13 is movably sleeved with hole 22 via hook 14. The anti-breakage mechanism also includes hole 35. Hole 315 is provided at the end of rubber block 9 away from power line 4. L-shaped actuating block 16 is movably installed on the right side inside the movable groove 5. Pull rope 17 is provided between L-shaped actuating block 16 and hole 315. The right end of pull rope 17 is fixedly sleeved with the upper end of L-shaped actuating block 16. The left side of L-shaped actuating block 16 is movably sleeved with hole 315 via hook 220.

[0028] In this embodiment, the dual protection mechanism of the pull strap 13 and the pull rope 17 can buffer the impact force and automatically trigger mechanical unlocking when the power cord 4 is subjected to abnormal tension, effectively preventing damage to the power connector 3 or breakage of the power cord 4, and improving the service life and safety of the equipment.

[0029] Working principle: When the power connector 3 needs to be plugged in, the operator presses the elastic clip 6 to retract it inward, causing the triangular block 7 to disengage from the initial position of the movable slot 5. At this time, the power connector 3 is aligned with the power socket 18 of the power terminal 2 and inserted. After it is fully plugged in, the elastic clip 6 is released. Under the action of elastic restoring force, the triangular block 7 pops outward and locks into the left side of the movable slot 5, forming a stable connection. At the same time, the sealing ring 8 ensures the sealing between the power terminal 2 and the power connector 3. In daily use, the pull strap 13 of the anti-breakage mechanism normally bears the pulling force of the power cord 4. When the external force exceeds the limit of the pull strap 13, the pull strap 13 breaks to protect the power connector 3 and the power cord 4. At this time, the pull rope 17 is forced to drive the L-shaped toggle block 16 to flip to the left. Through the lever action, the lower triangular block 7 is pressed down, causing it to disengage from the locking position of the movable slot 5. The power connector 3 then automatically disengages from the power terminal 2, thereby preventing the power connector 3 from being pulled and damaged or the power cord 4 from breaking.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
