Description

Technical Field

[0001] The invention relates to the technical application field of cable tie guns, and in particular to an electric cable tie gun. Background Art

[0002] Cable ties are commonly used for wire management applications (e.g., holding wires in place, bundling groups of wires together). Typically, a cable tie can be wrapped around multiple wires and then tightened to clamp the wires together. A cutting tool (e.g., a wire cutter) is then used to cut the tail of the cable tie.

[0003] Cable ties can be tightened or loosened to achieve a tension level that provides the appropriate rigidity or flexibility. Whether this is done with the aid of a tool or by hand, maintaining consistent tension can be very difficult. For example, a tool may provide inconsistent tensioning of the cable tie due to wear during a period of use.

[0046] like Figure 1-Figure 7 As shown, the present invention specifically relates to an electric cable tie gun, comprising:

[0047] Housing 100;

[0048] The cable tie fastening assembly 300 is disposed in the housing 100 and includes a fastening pawl 320 and a fastening connecting rod 310 used in conjunction with the cable tie, and one end of the fastening connecting rod 310 is movably connected to the fastening pawl 320 via a torsion spring;

[0049] A cutting assembly 400 is disposed in the housing 100 and is configured to cut the cable tie after the cable tie is tightened by the cable tie fastening assembly 300. The cutting assembly 400 includes a blade 420 and a cutting link 410.

[0050] The power transmission system 200 is disposed in the housing 100, and includes a motor 210 and a connecting rod assembly 500 connected to the output end of the motor 210, wherein the connecting rod assembly 500 is movably connected to the fastening connecting rod 310 and the cutting connecting rod 410 respectively;

[0051] When the output end of the motor 210 rotates to position A, the cable tie is tightened by the cooperation of the connecting rod assembly 500, the fastening connecting rod 310 and the fastening pawl 320;

[0052] When the output end of the motor 210 continues to rotate to the B position, the cable tie is cut through the cooperation of the connecting rod assembly 500, the cutting connecting rod 410 and the blade 420.

[0053] It should be noted that the output end of the motor 210 is connected to a cam, and a guide rod 220 is provided at the upper end of the cam, which is connected to the connecting rod assembly 500 through the guide rod 220 to transmit the power of the motor 210.

[0054] In addition, the connecting rod assembly 500 is connected to the fastening connecting rod 310 and the cutting connecting rod 410 respectively, so as to provide external force for tightening and cutting the cable tie; when the cable tie needs to be tightened and cut, the motor 210 drives the connecting rod assembly 500 to move through the guide rod 220, and the connecting rod assembly 500 drives the fastening connecting rod 310 to move. During the movement, the cable tie is fixed and tightened by the fastening pawl 320. Since the fastening pawl 320 is connected to the fastening connecting rod 310 through a torsion spring, when the fastening pawl 320 is in an open state, it is convenient for the cable tie to pass through. When the fastening pawl 320 follows the fastening connecting rod 310 to perform the tightening action, the fastening pawl 320 is closed to fix and tighten the cable tie.

[0055] When the cable tie is tightened, the guide rod 220 of the motor 210 reaches position A. At this time, the fastening link 310 can no longer move. The guide rod 220 located at the motor 210 continues to rotate to position B, and drives the cutting link 410 to rotate through the connecting rod assembly 500 to complete the cutting of the cable tie.

[0056] The connecting rod assembly 500 includes a transmission rod 510 connected to the output end of the motor 210, a driving rod 520 whose rotating shaft is connected to the transmission rod 510, a linkage rod 530 provided on the driving rod 520, and an arm rod 540;

[0057] One end of the arm 540 is connected to the cutting link 410, and the other end of the arm 540 is connected to the driving rod 520.

[0058] One end of the connecting rod 530 is connected to the fastening connecting rod 310 through a rotating shaft, and the other end of the connecting rod 530 is connected to the driving rod 520 through a rotating shaft.

[0059] The transmission rod 510 is provided with a guide block, and the housing 100 is provided with a guide groove 150 used in conjunction with the guide block. When the motor 210 is started, the transmission rod 510 reciprocates along the length direction of the guide groove 150 .

[0060] It should be noted that the process of tightening the cable tie has been described above, and the force for moving the fastening link 310 passes through the guide rod 220, the transmission rod 510, the drive rod 520 and the connecting rod 530 in sequence, and finally reaches the fastening link 310, driving the fastening link 310 to move.

[0061] When the cable tie is tightened and the fastening link 310 cannot move, the motor 210 drives the guide rod 220 to continue rotating. At this time, the connection between the connecting rod 530 and the driving rod 520 shaft acts as a lever, and the driving rod 520 rotates along the axial direction of the connecting rod 530 and the driving rod 520 shaft. During the rotation of the driving rod 520, the arm rod 540 is driven to rotate, and then the external force is transmitted to the cutting link 410 through the arm rod 540 to complete the cutting of the cable tie.

[0062] The feed end of the housing 100 is provided with a limit block 110 used in conjunction with the fastening pawl 320. The fastening pawl 320 has two states relative to the limit block 110:

[0063] When the fastening pawl 320 abuts against the limit block 110, the cable tie can be moved relative to the fastening pawl 320 for feeding;

[0064] When the fastening clamp is separated from the limiting block 110 , the fastening pawl 320 is used to fasten the cable tie.

[0065] The fastening link 310 is provided with a plurality of slide bars 312, and the housing 100 is provided with a fastening groove 140 used in conjunction with the slide bars 312. The fastening link 310 moves along the length direction of the fastening groove 140 through the slide bars 312, and the other end of the fastening link 310 is connected to the driving rod 520 through the connecting rod 530. The setting of the slide bars 312 and the fastening grooves 140 ensures the smoothness and stability of the fastening link 310 during movement.

[0066] In addition, the linkage rod 530 is connected to the fastening link 310 via the sliding rod 312 .

[0067] A fixing plate 550 is further disposed on the outer side of the arm 540, one end of the fixing plate 550 is connected to the driving rod 520 with the rotating shaft of the arm 540, and the other end of the fixing plate 550 is positioned and connected to the housing 100. The setting of the fixing plate 550 ensures the smoothness and stability of the movement process of the entire connecting rod assembly 500.

[0068] The cutting link 410 is provided with a cutting positioning shaft 411, and the housing 100 is provided with a cutting positioning hole 120 used in conjunction with the cutting positioning shaft 411. The cutting link 410 can rotate along the axial direction of the cutting positioning shaft 411 to achieve cutting of the cable tie.

[0069] As mentioned above, the driving rod 520 is connected to the rotating shaft of the arm rod 540, and the arm rod 540 is connected to the rotating shaft of the cutting link 410. Therefore, the entire cable tie cutting process is:

[0070] After the cable tie is tightened, the position of the fastening link 310 will not change, and the motor 210 drives the guide rod 220 to continue to rotate. At this time, the connection between the connecting rod 530 and the driving rod 520 shafts acts as a lever, and the driving rod 520 rotates along the axial direction of the connecting rod 530 and the driving rod 520 shafts. During the rotation of the driving rod 520, the arm rod 540 is driven to rotate, and then the external force is transmitted to the cutting link 410 through the arm rod 540. The cutting link 410 rotates along the axial direction of the cutting positioning shaft 411 to drive the blade 420 to cut the cable tie. In this process, the cutting positioning shaft 411, the driving rod 520 and the connecting rod 530 shafts act as levers to realize the entire cutting process.

[0071] A reset mechanism is provided at the connection between the driving rod 520 and the arm 540, and the reset mechanism includes a connection block 610 clamped at the connection between the driving rod 520 and the arm 540, and the connection block 610 is provided with two shafts including a connection positioning shaft 611 and a connection sliding shaft 612, and the housing 100 is provided with a connection positioning hole 130 and a connection sliding groove 170 used in conjunction with the connection positioning shaft 611 and the connection sliding shaft 612;

[0072] The connecting sliding shaft 612 is connected to the tension adjustment mechanism 600 through a bracket 620 .

[0073] Since the connecting block 610 is clamped at the connection between the arm 540 and the driving rod 520, when the positions of the arm 540 and the driving rod 520 change, one end of the connecting block 610 is always clamped at the connection between the arm 540 and the driving rod 520, and the connecting block 610 rotates axially along the connecting positioning shaft 611. During the rotation, the connecting sliding shaft 612 moves along the length direction of the connecting groove 170 of the shell 100, and then moves relative to the tension adjustment mechanism 600 through the bracket 620.

[0074] The tension adjustment mechanism 600 includes an adjustment rod 630 disposed on the housing 100 through a fixing sleeve 640. The adjustment rod 630 passes through the bracket 620 and is connected to a knob 650. A spring 631 is provided between the adjustment rod 630 and the bracket 620. The adjustment rod 630 is rotated by the knob 650 to adjust the tension of the spring 631.

[0075] During the whole process, unless the tension of the spring 631 is adjusted by the knob 650, the position of the adjustment rod 630 will not change; when the bracket 620 moves relative to the adjustment rod 630, the spring 631 between the bracket 620 and the adjustment rod 630 will be compressed or reset.

[0076] The change in position of the adjusting rod 630 affects the tensioning force of the spring 631 between the adjusting rod 630 and the bracket 620, thereby affecting the entire cutting process and the tensioning process.

[0077] According to different application scenarios of the cable tie, the tension of the spring 631 is adjusted by the knob 650, thereby adjusting the tension of the cable tie.

[0078] When there is a cable tie and the cable tie gun is idling, the transmission rod 510 is provided with a guide block, and the housing 100 is provided with a guide groove 150 used in conjunction with the guide block. When the motor 210 is started, the transmission rod 510 reciprocates along the length direction of the guide groove 150.

[0079] The force of the fastening link 310 moving passes through the guide rod 220, the transmission rod 510, the driving rod 520 and the connecting rod 530 in sequence, and finally reaches the fastening link 310, driving the fastening link 310 to move.

[0080] During this process, since there is no cable tie, the fastening link 310 keeps reciprocating, the position of the connecting block 610 does not change, and thus the connecting block 610 does not drive the bracket 620 to move relative to the adjusting rod 630, and the tension of the spring 631 does not change.

[0081] When there is a cable tie, the force of the fastening link 310 moving passes through the guide rod 220, the transmission rod 510, the driving rod 520 and the connecting rod 530 in sequence, and finally reaches the fastening link 310, driving the fastening link 310 to move.

[0082] During this process, the driving rod 520 rotates slightly. During the rotation process, the driving rod 520 drives the connecting block 610 to rotate. The connecting block 610 drives the bracket 620 to move relative to the adjusting rod 630 through the connecting sliding shaft 612. When the tensioning force of the cable tie reaches the value adjusted by the knob 650, the movement of the bracket 620 relative to the adjusting rod 620 stops. Due to the above-mentioned connection relationship, the fastening link 310 can no longer move.

[0083] In addition, when the motor 210 continues to rotate, the drive rod 520 drives the connecting block 610 to rotate during the rotation process, and the connecting block 610 drives the bracket 620 to move relative to the adjustment rod 630 through the connecting sliding shaft 612. At this time, the force applied by the motor 210 has exceeded the value set by the knob 650, so the cutting process is directly transferred. The driving rod 520 rotates more to drive the arm 540 to move, thereby completing the cutting of the cable tie.

[0084] In combination with the cable tie cutting process described above, when the connecting block 610 rotates along the connecting positioning shaft 611, the bracket 620 moves relative to the adjusting rod 630, thereby compressing the spring 631 between the bracket 620 and the adjusting rod 630; when the cable tie is cut, the elasticity of the spring 631 is used again to reset the connecting block 610, thereby resetting the blade 420. The entire resetting process is similar to the external force transmission process of cutting, with the only difference being that the connecting block 610 drives the driving rod 520 to move, thereby driving the arm rod 540 to rotate through the driving rod 520.

[0085] It also includes a locking block 700 arranged on the housing 100 through a torsion spring shaft assembly, one end of the locking block 700 abuts against the connecting block 610, and the other end of the locking block 700 is provided with an active tooth 710, and the end of the fastening link 310 is provided with a rack 313 used to cooperate with the active tooth 710, and the active tooth 710 is meshed with the rack 313 to fix the fastening link 310.

[0086] The housing 100 is provided with a locking positioning hole 160 for use with the torsion spring shaft assembly.

[0087] During the cutting process, since the connecting block 610 rotates along the connecting positioning shaft 611 and one end of the locking block 700 is always in contact with the connecting block 610, the torsion spring of the locking block 700 is always in a compressed state during this process. When the connecting block 610 rotates, the locking block 700 also rotates through the spring 631 of the torsion spring. Finally, the active tooth 710 provided on the locking block 700 and the rack 313 of the fastening link 310 are engaged, thereby preventing the fastening link 310 from changing position or shaking of components due to the loss of the tensioning force of the cable tie at the moment the cable tie is cut.

[0088] When the cutting is completed and the blade 420 enters the reset action, the locking block 700 is driven to rotate through the connecting block 610. During the rotation, the active tooth 710 is separated from the rack 313, so that the fastening connecting rod 310 can move again.

[0089] The fastening link 310 is provided with a pawl shield 311 used in conjunction with the fastening pawl 320 .
