Description

Technical Field

[0001] The utility model relates to the technical field of cable tie guns, in particular to a handheld nylon cable tie gun. Background Technique

[0002] A cable tie gun, also known as a cable tie tool or a wire bundling tool, is a tool that uses mechanical principles to quickly install and fasten cable ties. After the user loads the cable tie into the gun body, aims at the object to be tied, and triggers the internal mechanical structure by pulling the trigger. This action will quickly tighten and lock the cable tie on the object, and at the same time, the excess part of the cable tie will be automatically cut off. The whole process usually only takes a few seconds, greatly improving work efficiency.

[0003] When using the cable tie gun, the sliding knob can be used to limit and unlock the spring tension adjustment knob. However, during the sliding process of the knob, it is necessary to first unscrew the bolt on its surface, then install it in another hole. After turning the knob to adjust the spring tension, the bolt needs to be unscrewed again and installed in another hole to limit the position of the knob, so that the knob can stably limit the knob. The operation is relatively troublesome and can be further improved. Content of the Utility Model

[0041] See also Figure 1 - Figure 2 A handheld nylon cable tie gun includes a housing 100, which is composed of two half shells, and the two half shells are fixed together by bolts. A wrench assembly 200 is movably connected to the bottom of the housing 100, and a pulling assembly 300 and a shearing assembly 400 are arranged inside the housing 100, and the pulling assembly 300 is used to clamp the cable tie and pull it to the right to tighten the cable tie; the shearing assembly 400 is used to shear the excess part of the tightened cable tie. During the rightward deflection of the wrench assembly 200, the pulling assembly 300 is driven to move to the right, and during the rightward movement of the pulling assembly 300, the front end of the shearing assembly 400 is driven to tilt upward, and the rear end of the shearing assembly 400 is provided with an elastic force adjustment assembly 500, and a limit assembly 600 is arranged on the upper side of the elastic force adjustment assembly 500, and the limit assembly 600 is connected to the top of the housing 100 through sliding.

[0042] See also Figure 1 A handle 101 is integrally formed on the lower right side of the housing 100, and a gun head cover 102 is fixedly installed at the gun head of the left end of the housing 100 by screws. A "I"-shaped slot for passing the cable tie is opened through the surface of the gun head cover 102, and a through slot 103 is opened on the upper left end of the housing 100. Part of the structure of the pulling assembly 300 passes through the through slot 103, and the cable tie passes through the "I"-shaped slot and is inserted into the left end of the pulling assembly 300. When the pulling assembly 300 moves to the right, the cable tie is tightened.

[0043] See also Figure 3 - Figure 6 The wrench assembly 200 includes a connecting shaft 201 disposed in the middle of the housing 100, and a pull arm 202 is rotatably connected to the surface of the connecting shaft 201. The pull arm 202 is composed of three layers. The inner layer and the middle layer of the pull arm 202 are both made of sheet metal, and the top of the inner layer and the middle layer are both rotatably connected to the connecting shaft 201. The outer layer of the pull arm 202 is a rubber layer coated on the outer side of the middle layer. When in use, hold the handle 101 and pull the pull arm 202 to the right with your fingers. The upper right side of the pull arm 202 is rotatably connected to a push plate 203, and the right end of the push plate 203 is rotatably connected to a deflection arm 204. The bottom end of the deflection arm 204 is hinged on the inner wall of the through groove 103, and the end of the push plate 203 is hinged in the middle of the deflection arm 204. A compensation groove 205 is provided on the top side of the deflection arm 204, and a sliding shaft 206 is inserted and inserted in the compensation groove 205. When the pull arm 202 is pulled to the right, the push plate 203 is driven to push the deflection arm 204 to the right, so that the deflection arm 204 deflects around its bottom end and pulls the sliding shaft 1 206 to the right.

[0044] See also Figure 3 - Figure 4The pulling assembly 300 includes a pulling plate 301 rotatably connected to the sliding shaft 1 206. Both sides of the middle of the pulling plate 301 are rotatably connected to pulleys 302. The pulleys 302 are laterally slidably connected to the inner wall of the housing 100, thereby limiting the moving path of the pulling plate 301 so that the pulling plate 301 can only move in the horizontal direction. When the deflection arm 204 deflects to the right, the pulling plate 301 is pulled to the right through the sliding shaft 1 206, and at the same time, the sliding shaft 1 206 slides in the compensation groove 205.

[0045] The top of the front end of the pulling plate 301 is rotatably connected to a clamping piece 303, and a torsion spring 304 is arranged inside the front end of the pulling plate 301. One end of the torsion spring 304 is clamped in the pulling plate 301, and the other end of the torsion spring 304 is attached to the bottom of the clamping piece 303, so that when the pulling plate 301 moves to the right, the torsion spring 304 is twisted, and the L-shaped baffle 305 is tilted upward through the elasticity of the torsion spring 304. An L-shaped baffle plate 305 is integrally formed on the rear side of the left end of the pulling plate 301, and the horizontal part of the L-shaped baffle plate 305 is located above the clamping piece 303. The clamping piece 303 and the L-shaped baffle plate 305 are slidably connected in the through groove 103, and the cable tie passes between the clamping piece 303 and the L-shaped baffle plate 305. When the clamping piece 303 is tilted upward, the L-shaped baffle plate 305 and the clamping piece 303 clamp and fix the cable tie from the upper and lower sides, and cooperate with the pulling plate 301 to move to the right, so that the cable tie is pulled to the right and is tightened.

[0046] A second torsion spring 307 is disposed inside the through slot 103, one end of which is clamped on the inner wall of the through slot 103, and the other end of which is attached to the right end of the pulling plate 301. Due to the elasticity of the second torsion spring 307, the pulling plate 301 has a tendency to move leftward, and after the pulling arm 202 is released, the pulling plate 301 can be driven to move leftward for reset by the second torsion spring 307.

[0047] A sealing plate 306 is clamped on the upper side of the left half of the pulling plate 301, and the sealing plate 306 is located below the opening of the through slot 103 and on the right side of the clamping piece 303. The sealing plate 306 is used to seal the opening of the through slot 103 to prevent the cable tie from being inserted into the housing 100 during the process of being inserted between the clamping piece 303 and the L-shaped baffle 305; and to prevent the cut cable tie from entering the housing 100 from the through slot 103.

[0048] See also Figure 4 - Figure 8 The shearing assembly 400 includes a hook 401 attached to the lower middle side of the connecting shaft 201. The hook 401 is in a hook shape, and an arc groove matched with the hook 401 is arranged at the bending part thereof, so that the hook 401 is stably arranged at the bending part of the hook 401.

[0049] A positioning shaft one 402 is rotatably connected through the lower side of the middle part of the hook 401, and the positioning shaft one 402 is rotatably connected to the inner wall of the housing 100, so that the hook 401 can deflect along the positioning shaft one 402. An inclined groove 403 is penetrated and opened on the upper side of the right half of the hook 401, and a sliding shaft two 404 is penetrated and inserted in the inclined groove 403;

[0050] A positioning shaft two 405 is arranged on the right side of the hook 401. The positioning shaft two 405 is fixedly installed on the inner wall of the housing 100. A deflection plate 406 is sleeved and rotatably connected to the outer side of the positioning shaft two 405. The deflection plate 406 is attached to the middle part of the right end of the hook 401. A torsion spring three 407 is arranged between the deflection plate 406 and the positioning shaft two 405. Due to the elasticity of the torsion spring three 407, the deflection plate 406 has a tendency to deflect to the left, so that the deflection plate 406 is closely attached to the right side of the hook 401.

[0051] A rack one 408 is integrally formed at the bottom of the deflection plate 406; a rack two 409 is engaged with the bottom of the rack one 408. The rack two 409 is fixedly installed at the top of the right end of the pulling plate 301. Thus, when the pulling plate 301 moves to the right, the rack two 409 moves to the right synchronously, and then the rack two 409 pushes the rack one 408 to the right, driving the deflection plate 406 to deflect counterclockwise, driving the hook 401 to deflect counterclockwise, and driving the connecting shaft 201 to move downward;

[0052] A connecting piece 410 is rotatably connected to the surface of the connecting shaft 201. The front end of the connecting piece 410 is rotatably connected to a lever 411. The lever 411 is located below the pulling plate 301. A positioning shaft three 412 is rotatably connected through the surface of the left half of the lever 411. The positioning shaft three 412 is rotatably connected to the inner wall of the housing 100. A cutter 413 is clamped at the front end of the lever 411. The cutter 413 is attached to the right side of the handle 101. When the connecting shaft 201 moves downward, it pushes the connecting piece 410 downward, driving the lever 411 to deflect around the positioning shaft three 412. The front end of the lever 411 pushes the cutter 413 upward, and the cable tie is blocked from above by the gun head cover 102, and the cutter 413 cuts off the cable tie.

[0053] Please refer to Figure 9 - Figure 10 , the elastic force adjustment assembly 500 includes a U-shaped plate 501 rotatably connected to the surface of the sliding shaft two 404. The U-shaped plate 501 is U-shaped. The sliding shaft two 404 penetrates through both ends of the left side of the U-shaped plate 501. Thus, when the hook 401 deflects counterclockwise, it will pull the U-shaped plate 501 to the left through the sliding shaft two 404.

[0054] A pull rod 502 is slidably connected through the middle part of the right side of the U-shaped plate 501. The cross section of the pull rod 502 is T-shaped. A spring one 503 is sleeved on the outer side of the pull rod 502. Both ends of the spring one 503 are respectively attached to the left end of the pull rod 502 and the right end of the U-shaped plate 501; due to the elasticity of the spring one 503, the U-shaped plate 501 has a tendency to move to the right.

[0055] A U-shaped plate 501 is sleeved with an internally threaded pipe 504 on the outer side of the right end. A slide rail 505 is fixedly installed on the upper part of the left end of the internally threaded pipe 504, and the slide rail 505 is fixedly installed with the housing 100. An externally threaded pipe 506 is threadedly connected to the inside of the right end of the internally threaded pipe 504. Threads are correspondingly arranged on the inner wall of the internally threaded pipe 504 and the outer wall of the externally threaded pipe 506. A connecting sleeve 507 is inserted into the right end of the externally threaded pipe 506, and the connecting sleeve 507 is threadedly connected to the right end of the pull rod 502. Threads are correspondingly arranged on the inner wall of the connecting sleeve 507 and the right end of the pull rod 502; as Figure 10 shown, two symmetrical planar parts are arranged in the middle of the pull rod 502, so that its cross-section is not circular, and a gasket is sleeved in the middle of the pull rod 502. The hole at the center of the gasket is adapted to the cross-section of the middle of the pull rod 502. The gasket is fixed on the inner wall of the internally threaded pipe 504, thereby inhibiting the rotation of the pull rod 502.

[0056] A knob 508 is sleeved on the outside of the externally threaded pipe 506, and the knob 508 is fixedly installed with the connecting sleeve 507. A plurality of notches are formed on the right end surface of the externally threaded pipe 506, and a plurality of ribs are correspondingly arranged on the inner wall of the knob 508. The externally threaded pipe 506 is slidably connected to the ribs through the notches, so that the knob 508 is slidably adapted to the externally threaded pipe 506. A decorative cover 509 is arranged at the right end of the knob 508. Thus, when the knob 508 is rotated, the connecting sleeve 507 rotates synchronously, driving the pull rod 502 to move left and right, and adjusting the compression amount of the first spring 503. A second spring 510 is arranged on the right side of the bottom of the slide rail 505, and the right end of the second spring 510 abuts against the inner wall of the knob 508.

[0057] Please refer to Figure 9 - Figure 13 , the limiting component 600 includes a slider 601 slidably connected to the top of the slide rail 505.

The first clamping block 604 is inserted between two adjacent second clamping blocks 605. Through the elasticity of the third spring 603, the slider 601 has a tendency to move to the right, and the first clamping block 604 is inserted between two adjacent second clamping blocks 605, inhibiting the rotation of the knob 508.

[0058] Please refer to Figure 11 - Figure 13 , an installation cavity 606 is arranged inside the slider 601. A rotating shaft hole 607 communicating with the installation cavity 606 is formed on the surface of the sliding button 602.

Both ends of the V-shaped metal sheets 612 are respectively located above the avoidance grooves 608. Blocking sheets 613 are fixedly installed on both the left and right side walls of the installation cavity 606. The blocking sheets 613 are attached to the top of the support plate 610. Due to the elasticity of the fourth spring 611, the support plate 610 has a tendency to move upward, and the blocking sheets 613 block the support plate 610, so that the V-shaped metal sheets 612 are located above the avoidance grooves 608.

[0060] A rotating shaft 614 is rotatably connected through the rotating shaft hole 607. A limiting ring 615 is fixedly installed on the surface of the rotating shaft 614. The assembly of the rotating shaft 614 and the limiting ring 615 is adapted to the rotating shaft hole 607. Through the setting of the limiting ring 615, the rotating shaft 614 can only rotate relative to the slider 601 and the sliding button 602, and cannot move up and down relative to the slider 601 and the sliding button 602. A push tube 616 is threadedly connected to the lower half of the rotating shaft 614. Threads are correspondingly arranged on the surface of the rotating shaft 614 and the inner wall of the push tube 616. Protrusions 617 are arranged in an array on the outer wall of the push tube 616. A guide ring 618 is sleeved outside the assembly of the push tube 616 and the protrusions 617. The assembly of the push tube 616 and the protrusions 617 is slidably adapted to the guide ring 618. A fixing column 619 is fixedly installed between the guide ring 618 and the top wall of the installation cavity 606. The push tube 616 is attached to the top of the support plate 610. Thus, the protrusions 617 are guided by the guide ring 618 to prevent the push tube 616 from rotating, so that the push tube 616 can only move in the vertical direction. When the rotating shaft 614 is rotated, the push tube 616 is driven to move up and down by the threaded connection between the rotating shaft 614 and the push tube 616. When the push tube 616 moves downward, it pushes the support plate 610 downward. The V-shaped metal sheets 612 pass through the avoidance grooves 608 and are attached to the surface of the slide rail 505. As the support plate 610 continues to move downward, the V-shaped metal sheets 612 are bent and deformed and closely attached to the surface of the slide rail 505, increasing the frictional force of the slider 601 sliding relative to the slide rail 505, thereby preventing the slider 601 from sliding.

[0061] During use, by rotating the rotating shaft 614, the push tube 616 is driven to move upward. Under the elastic action of the fourth spring 611, the support plate 610 moves upward, and the V-shaped metal sheets 612 are pulled out from the avoidance grooves 608. Then, the slider 601 is pushed to the left to separate the first latch 604 from the second latch 605. Then, the rotating shaft 614 is rotated in the reverse direction to make the support plate 610 move downward, and the V-shaped metal sheets 612 are closely attached to the surface of the slide rail 505, keeping the slider 601 separated from the knob 508.

[0062] Rotate the knob 508 again to drive the pull rod 502 to move left and right, thereby adjusting the compression amount of the first spring 503; after the adjustment is completed, rotate the rotating shaft 614 to move the push tube 616 upward, and the V-shaped metal sheet 612 is separated from the slide rail 505. Thus, under the elastic action of the third spring 603, the slider 601 moves to the right, and the first clamping block 604 is inserted between the second clamping blocks 605 to inhibit the rotation of the knob 508.

[0063] Hold the through groove 103 by hand and pull the lever arm 202 with your finger to deflect the lever arm 202 to the right. The push plate 203 pushes the deflecting arm 204 to the right, causing the deflecting arm 204 to deflect clockwise around its bottom end. Thus, the top end of the deflecting arm 204 pushes the pulling plate 301 to the right through the first sliding shaft 206. During the rightward movement of the pulling plate 301, the first torsion spring 304 twists, causing the clamping piece 303 to tilt upward, and the clamping piece 303 and the L-shaped baffle 305 clamp and fix the cable tie. Then, by moving the pulling plate 301 to the right, the cable tie is pulled.

[0064] When the pulling plate 301 moves to the right, the second rack 409 pushes the first rack 408 to the right, driving the deflecting plate 406 to deflect counterclockwise around the second positioning shaft 405, and pushing the hook 401 to deflect counterclockwise through the deflecting plate 406, causing the connecting shaft 201 to move downward. Through the connection of the connecting piece 410, the lever 411 is pushed to deflect clockwise around the third positioning shaft 412. The front end of the lever 411 tilts upward, and the cutter 413 fits and moves upward on the gun head cover 102, cooperating with the gun head cover 102 to block the cable tie from above, thereby cutting the cable tie.

The scope of the present invention is defined by the appended claims and their equivalents.
