Description

Technical Field

[0001] The utility model relates to the technical field of high-branch shears, in particular to a scissors extension rod with a power amplification component and the high-branch shears using the same. Background Art

[0002] The applicant previously applied for a Chinese invention application with publication number CN117256339A, “A medium and long distance shearing device and control method”. This type of shearing device uses a soft traction line or traction belt for transmission. While being able to shear objects at high places, it can also be used to achieve insulating shearing.

[0003] Due to the limitation of the tensile strength of the soft wire, it cannot reach the tensile strength of steel parts. Therefore, after the power is transmitted to the soft wire, a specific structure is required to amplify the power transmitted by the soft wire and then transmit it to the end (corresponding to the position of the moving blade) to ensure the service life of the soft wire.

[0004] To this end, the Chinese utility model "Guide rope control structure for high branch shears" with announcement number CN201911086U proposes a similar power amplification and labor-saving design. "The high branch shears have a fixed wheel seat and a slidable movable wheel seat fixed in the extension rod. The fixed wheel seat and the movable wheel seat are respectively provided with a plurality of rollers and a plurality of pulleys, and the guide rope is arranged between the rollers of the fixed wheel seat and the pulley of the movable wheel seat. Pulling the guide rope can link the movable wheel seat to produce sliding and link the shears head to perform shearing. The connection relationship between the guide rope, the fixed wheel seat and the movable wheel seat can control the high branch shears to perform shearing action", achieving the effect of saving shearing force, that is, the power of the guide rope can be amplified, which can provide the scissors with greater shearing force.

[0005] However, this labor-saving design currently requires the installation of a fixed wheel inside the long rod. During installation, the fixed wheel is inserted into the long rod, and after the axial hole of the fixed wheel is aligned with the through hole outside the long rod, a positioning pin is inserted from the through hole outside the long rod into the inside of the long rod, and the positioning pin is matched with the axial hole of the fixed wheel, so that the fixed wheel is limited to rotate at this position. As proposed in CN201911086U, "the fixed wheel seat is placed in the accommodation space of the extension rod, and is fixed by a pin passing through the pin hole and the through hole". During installation, it is necessary to align the corresponding holes from the outside of the rod with the inside of the rod, and the entire installation process is relatively difficult.

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] See also Figure 1-2 A scissors extension rod with a power amplification component is used to transmit the traction input by the traction input component to the moving blade of the scissors. The scissors extension rod includes a rod body 1 and a power amplification component 2.

[0038] One end of the rod body 1 is a blade mating end 101 , and the other end of the rod body 1 is a traction force input end 102 . The rod body 1 is hollow inside, and a first communication port 103 connected to the inside of the rod body 1 is provided on the blade mating end 101 .

[0039] The power amplifying assembly 2 includes a connecting rail 201 penetrating into the rod body 1 from the first connecting port 103 ; a fixing seat 202 is connected to the connecting rail 201 near the traction force input end 102 , and a fixed guide wheel set 203 is connected to the fixing seat 202 .

[0040] A first sliding seat 204 is slidably disposed on the connecting rail 201. The first sliding seat 204 has a positive sliding direction toward the fixed guide wheel set 203 and a reverse sliding direction toward the first connecting port 103 in the rod body 1. A movable guide wheel set 205 is connected to the first sliding seat 204.

[0041] A one-way positioning member 206 is connected to a portion of the connecting guide rail 201 close to the first connecting port 103 , and a stopper 104 is correspondingly provided on the blade mating end 101 to limit the one-way positioning member 206 from continuing to move in the positive sliding direction.

[0042] The power amplification component 2 also includes a traction line 105; the traction line 105 has a free end 1051 and a fixed end 1052, and at least one winding section 1053 is formed between the free end 1051 and the fixed end 1052, and the winding section 1053 is wound on the fixed guide wheel group 203 and the movable guide wheel group 205.

[0043] The free end 1051 penetrates into the traction input end 102 along the length direction of the rod body 1 , and is pulled from the blade mating end 101 to the traction input end 102 by the traction input component.

[0044] The power amplification assembly 2 also includes a linkage power transmission member 106 for linking the first sliding seat 204 with the moving blade of the scissors. The power input end of the linkage power transmission member 106 cooperates with the power of the first sliding seat 204, and the power output end of the linkage power transmission member 106 cooperates with the power of the moving blade of the scissors.

[0045] When the moving blade of the scissors is pulled to move, the traction force applied to the first sliding seat 204 is amplified by the formed winding segment 1053. Ideally, the traction force can be increased by 2 times for each additional winding segment. Taking the traction force applied by the traction force input component to the free end 1051 as F for example, the traction force applied to the first sliding seat 204 can be increased by 2F for each additional winding segment.

[0046] When the traction force input component is pulling, the connecting guide rail 201 is subjected to a pulling force toward the traction force input end 102 , so that the one-way positioning member 206 of the connecting guide rail 201 can generate a resistance limit with the in-place stopper 104 , thereby forming a holding mechanism for the connecting guide rail 201 .

[0047] That is, in fact, both the fixed guide wheel group 203 and the movable guide wheel group 205 can be pre-installed on the connecting guide rail 201, and then the traction line 105 is wound accordingly, and then the connecting guide rail 201 loaded with the fixed guide wheel group and the movable guide wheel group is inserted into the rod body 1, and is positioned and maintained by the one-way positioning member 206 and the in-place stop member 104 during the traction process, so that it is more convenient to install the fixed guide wheel group 203 into the corresponding position in the rod body 1, and it is also more convenient to assemble the connecting guide rail 201 on the rod body 1.

[0048] like Figure 2 As shown, only one wheel is provided for each of the fixed guide wheel group 203 and the movable guide wheel group 205, and the winding section between the fixed guide wheel group 203 and the movable guide wheel group 205 is one circle. Different numbers of winding sections can be provided according to different power amplification requirements, and in order to make the power amplification process smoother, the fixed guide wheel group and the movable guide wheel group can be provided with corresponding numbers of wheels.

[0049] The fixed guide wheel assembly 203 is shown as being held on the fixed seat 202, and it itself may be rotatable or non-rotatable; when the fixed guide wheel assembly 203 has multiple wheels, some of the wheels may be rotatable while the other wheels may not be rotatable.

[0050] The movable guide wheel group 205 is shown to be maintained on the first sliding seat 204 and can move with the first sliding seat 204. It itself can be rotatable or non-rotatable. When the movable guide wheel group 205 has multiple wheels, some of the wheels can rotate while the other wheels cannot rotate.

[0051] Preferably, the free end 1051 of the traction line 105 is connected to the first sliding seat 204, which is equivalent to winding an extra 0.5 turns of the winding section. Ideally, the traction force can be amplified by 1 times.

[0052] See also Figure 1-6 In an embodiment of the utility model, a high branch shear comprises a scissors extension rod of the above embodiment. The high branch shear also comprises a mounting frame 3 and an elastic reset member 6.

[0053] The mounting frame 3 is mounted on the blade matching end 101 of the rod body 1 ; a moving blade 4 and a counter blade 5 are mounted on the mounting frame 3 , and the moving blade 4 matches with the counter blade 5 in a rotational manner.

[0054] Please participate in Figure 3 The movable blade 4 is rotatably connected to the mounting frame 3 through a pin shaft, and is shear-matched with the counter blade 5 in a rotational manner.

[0055] The elastic reset member 6 is arranged between the movable blade 4 and the mounting frame 3; when the movable blade 4 rotates and shears relative to the counter blade 5, the elastic reset member 6 is in an elastic deformation state corresponding to the joint force of the movable blade 4 and the mounting frame 3; the elastic deformation recovery of the elastic reset member 6 correspondingly drives the movable blade 4 to rotate and open relative to the counter blade 5.

[0056] Please participate in Figure 3 The elastic reset member 6 can be a tension spring, one end of which is connected to the movable blade 4, and the other end of which is connected to the mounting frame 3. The tension spring is used to open the movable blade 4 by the elastic force of the tension spring. That is, when the traction force applied by the traction force input component disappears, or when the traction force is weakened to be lower than the elastic force of the tension spring, the elastic reset member can provide power for the opening action of the movable blade.

[0057] A length adjustment rod 7 is provided on the sliding sleeve of the rod body 1 , and a position retaining member 8 is provided between the length adjustment rod 7 and the rod body 1 for positioning and retaining the length adjustment rod 7 on the rod body 1 after sliding to adjust its position.

[0058] The position retaining member 8 comprises a connecting sleeve 801 connected to the length adjusting rod 7, an adjustable locking sleeve 802 sleeved on the rod body 1 is formed on the connecting sleeve 801, and a locking wrench 803 for adjusting the locking degree of the adjustable locking sleeve 802 is arranged on the adjustable locking sleeve 802. By rotating the locking wrench 803, the locking degree of the adjustable locking sleeve 802 can be changed from tightening to loosening or from loosening to tightening.

[0059] The adjustable locking sleeve 802 corresponds to a sleeve body with discontinuous sides, which enables the sleeve body to have elastic clamping characteristics. When the locking wrench 803 is rotated, the sleeve body is clamped and shrunk, thereby clamping the rod body 1.

[0060] The traction force input end 102 is provided with a second communication port 107 connected to the interior of the rod body 1 .

[0061] A traction input component 9 is provided on the end of the length adjustment rod 7 away from the movable blade 4. The traction input component 9 includes a motor bracket 901 installed on the length adjustment rod 7. A traction motor 902 and a winding wheel driven by the traction motor 902 are installed on the motor bracket 901. The winding action of the winding wheel is suitable for driving the free end 1051 of the traction wire 105 to be pulled from the blade mating end to the traction input end.

[0062] A guide rail is formed inside the traction input end 102 along the length direction of the traction input end, a second sliding seat 903 is slidably arranged on the guide rail, and an adapting guide wheel 904 is connected to the second sliding seat 903 ; the free end 1051 of the traction line 105 is connected to the second sliding seat 903 .

[0063] The traction input component 9 also includes an adapter wire 905, one end 905a of the adapter wire 905 is wound on the winding wheel; the other end 905b of the adapter wire 905 passes through the second connecting port 107 from the length adjustment rod 7, continues to penetrate into the adapter guide wheel 904 along the length direction of the rod body 1, and is wound on the adapter guide wheel 904, then changes direction to pass through the second connecting port 107, and after passing through the rod body 1 from the second connecting port 107, continues to change direction along the periphery of the second connecting port 107 to enter the gap 906 between the outer side of the rod body 1 and the inner wall of the length adjustment rod 7, and continues to penetrate into the gap 906 along the length direction of the rod body and in the direction away from the second connecting port 107 in the gap 906, and is finally connected to the length adjustment rod 7.

[0064] When the connecting sleeve of the position retaining member is connected to the length adjusting rod, the other end 905b of the adapter line 905 may be finally connected to the connecting sleeve to reduce the drilling process on the length adjusting rod.

[0065] On the one hand, through the setting of the second sliding seat 903 and the winding of the adapter wire 905, the rotational force of the traction motor 902 on the winding wheel can be amplified to the second sliding seat 903, thereby acting on the free end 1051 of the traction wire connected to the second sliding seat 903; on the other hand, when the rod body 1 cooperates with the length adjustment rod 7 to perform telescopic length adjustment, there is no need to change the winding length of the adapter wire 905 and the unwinding length of the adapter wire 905 of the winding wheel, thereby effectively ensuring the traction accuracy after the telescopic adjustment, that is, effectively ensuring the accuracy of the final shear control of the moving blade.

[0066] Preferably, the guide rail is formed by the outer side of the rod body 1 being recessed inwardly, and the gap 906 through which the adapter line 905 penetrates is formed on the outer side of the rod body 1 by the outer side of the rod body 1 being recessed inwardly, that is, the guide rail and the above-mentioned gap 906 can be obtained simultaneously by one recessing process.

[0067] The linkage power transmission member 106 comprises a pull rod, one end of which is rotatably connected to the first sliding seat 204, and the other end of which is rotatably connected to the lever portion of the movable blade 4. The pull rod can be made of a strong material to be suitable for the traction amplified by the power amplification component.

[0068] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
