Description

Technical Field

[0001] The invention relates to the technical field of electrical engineering, and in particular to a wire stripper. Background Art

[0002] The traditional definition of electrical engineering is the sum of related disciplines used to create electrical and electronic systems. This definition was originally very broad, but with the rapid development of science and technology, the current concept of electrical engineering has far exceeded the scope of the above definition. A professor at Stanford University pointed out: "Today's electrical engineering covers almost all engineering behaviors related to electronics and photons." It is the tremendous progress in electronic technology that has promoted the arrival of the information age based on computer networks and changed all aspects of human life and work. The electrical engineering discipline in American universities, also known as the Department of Electrical Engineering, the Department of Electrical Engineering and Information Science, the Department of Electrical Engineering and Computer Science, etc., mainly focuses on computer and information technology. In electrical engineering construction, it is often necessary to cooperate with some instruments and tools to enable various electrical engineering tasks to proceed in an orderly manner. Wire strippers are a tool that electrical engineering workers often need to use.

[0003] The springs of existing electrical engineering wire strippers are mostly connected in a clip-on manner, which results in the spring being easily detached due to repeated expansion and contraction when the workers use the wire strippers to strip wires. Once the spring detaches, the use of the wire strippers will be very troublesome, affecting the subsequent wire stripping work and causing inconvenience to the workers. Moreover, most of the existing electrical engineering wire strippers cannot be folded and stored, which makes it extremely inconvenient for the workers to carry the wire strippers with them. The wire strippers cannot be put into the pocket of their work clothes and they need to be equipped with a tool box or tool bag, which increases the burden on the workers.

[0004] In addition, wires are made of various materials and models. When using wire strippers, if you are not careful, it is easy to cut the conductor inside the wire, affecting the performance of the wire.

[0005] Moreover, a return spring is arranged between the two handles of the wire stripper, and the spring is pressed when the handle is pressed. After the hand is released, the two handles will be separated quickly due to the elastic force of the spring, which may easily injure the hands of the staff. Summary of the invention

[0006] In view of the deficiencies in the prior art, the invention solves the technical problem of providing a wire stripper to solve the problem that the spring on the wire stripper easily falls off.

[0007] In order to solve the above problems, the technical solution adopted by the invention is: a wire stripper, comprising a wire stripping part, a hinge part and a handle, wherein a second spring is arranged on the handle of the wire stripper; the two ends of the second spring are respectively connected to the parts of the two handles of the wire stripper close to the hinge part; the handle of the wire stripper is in the shape of a rectangular parallelepiped, and the second spring is installed on the handle through a fixing assembly; the fixing assembly comprises an installation cavity provided at a position corresponding to the second spring on the handle, and a connecting groove is provided on the parts of the handle located on both sides of the installation cavity, one end of the connecting groove is communicated with the installation cavity, and the other end of the connecting groove passes through the other outer side wall of the handle; a sliding block is slidably connected inside the connecting groove, and a mounting block is slidably connected inside the mounting cavity, and the mounting block passes through the other side wall of the handle; an installation groove is provided on the mounting block, and a telescopic rod is arranged inside the installation groove, and the outer surface of the telescopic rod is sleeved with a first spring, and one end of the telescopic rod is fixedly connected to a fixing block, and the fixing block is slidably matched with the connecting groove and the mounting groove at the same time; the number of the installation cavities is set to 2 and they are relatively arranged on the two handles; the two ends of the second spring are respectively fixed on the two mounting blocks.

[0008] The technical principle of this technical solution is:

[0009] 1. The wire stripper comprises a wire stripping part, a hinge part and a handle, wherein the handle of the wire stripper is provided with a second spring; the two ends of the second spring are respectively connected to the parts of the two handles of the wire stripper close to the hinge part;

[0010] 2. Set up the installation cavity, installation block and other structures, and the two ends of the second spring are fixed on the two installation blocks, so the second spring is not easy to fall off; when the second spring needs to be replaced, press the sliding block inward, and the sliding block pushes the fixed block inward to move inward. The fixed block moves inward to shrink the telescopic rod and the first spring. At this time, the installation block loses its limit, and the two installation blocks together with the second spring can be removed. After the new geothermal spring is installed on the two installation blocks, align the installation block with the installation cavity and insert it. The fixed block will move inward and shrink the telescopic rod and the first spring. Continue to push the installation block until the telescopic rod and the first spring return to their original length, push the fixed block into the connecting groove, and the replacement of the second spring can be completed.

[0011] The beneficial effect of the present invention is that the invention optimizes the spring connection method of the wire stripper for electrical engineering. By setting the wire stripper, the sliding block and the fixed block, the sliding block is pressed inward, and the sliding block pushes the fixed block to move inward. The fixed block moves inward to contract the telescopic rod and the first spring. At this time, the installation block loses its limit, so that the second spring will not fall off easily after installation and is easy to replace, which reduces unnecessary trouble for the staff and makes the wire stripper more convenient to use.

[0012] Furthermore, the mounting cavity and the mounting block are both configured to be rectangular parallelepiped, and the cross section of the fixing block is a right-angled trapezoidal shape.

[0013] The mounting cavity and the mounting block are both set in a rectangular parallelepiped shape to facilitate taking out the mounting block or installing the mounting block into the mounting cavity. The cross section of the fixing block is a right-angle trapezoidal shape to facilitate the installation of the mounting block.

[0014] Furthermore, the cross sections of the connecting groove and the sliding block are both arranged in an I-shape. The sliding block can slide relative to the connecting groove but cannot completely slide out of the connecting groove.

[0015] Furthermore, a storage assembly is provided on the handle of the wire stripper, and the storage assembly includes a connecting block fixed on the wire stripping part, a first sliding groove and a second sliding groove are provided inside the connecting block, the size of the first sliding groove is smaller than the size of the second sliding groove, the first sliding groove and the second sliding groove are connected and form a T-shaped sliding through groove, a fixing rod is slidably connected inside the sliding through groove, and the fixing rod passes through the first sliding groove and the second sliding groove to the outside of the connecting block, a third spring is sleeved on the outer surface of the fixing rod, a fixing ring is sleeved on the outer surface of the fixing rod, and the fixing ring is slidably connected to the second sliding groove; the storage assembly also includes a connecting rod hinged on the handle, a fixing hole matching the fixing rod is provided on the connecting rod; the number of the connecting blocks is set to two and they are centrally symmetrically distributed on the wire stripping part; the number of the connecting rods is set to two and they are symmetrically distributed on the two handles.

[0016] The connecting rod is rotated relative to the handle to achieve folding of the connecting rod, and then the fixing rod is pulled to align the fixing hole with the fixing column, and then the fixing rod is released, and the third spring pushes the fixing ring and the fixing rod into the fixing hole on the connecting rod, so that the connecting rod can be limited, thereby achieving the folding and storage of the wire strippers, so that the volume occupied by the wire strippers when not in use can be reduced, making the wire strippers more portable and providing convenience for electrical engineering work.

[0017] Furthermore, the cross section of the connecting block is "L" shaped. The connecting rod is folded and placed on the connecting block, which is convenient for limiting the connecting rod.

[0018] Furthermore, a handle is fixed on the fixing rod to facilitate pulling the fixing rod.

[0019] Furthermore, the handle includes a first handle and a second handle arranged opposite to each other; the buffer mechanism includes a cavity on the first handle, the interior of the cavity is slidingly sealed with a sliding plug, the sliding plug divides the cavity into an upper cavity and a lower cavity, the sliding plug is provided with a through hole, and the cavity is filled with a non-Newtonian fluid; a first groove is provided on the portion of the first handle located below the cavity, and a second groove is provided on the second handle, the openings of the first groove and the second groove are arranged opposite to each other, a rotating rod is hinged at the upper end of the second groove, an end of the rotating rod away from the second groove is stuck in the first groove and can slide up and down along the first groove; the portion of the rotating rod located in the first groove is hinged to the sliding plug through a connecting rod; a fourth spring is provided inside the upper cavity, one end of the fourth spring is fixed to the top of the upper cavity, and one end of the fourth spring is fixed to the sliding plug.

[0020] Non-Newtonian fluids flow when subjected to a slow force, but become hard solids when subjected to a sudden external force.

[0021] When the operator's hand presses the two handles to bring the two handles together, the rotating rod rotates downward relative to the first groove, and the part of the rotating rod located in the first groove slides along the first groove. The first groove pulls the sliding plug downward through the connecting rod, and the non-Newtonian fluid in the lower cavity enters the upper cavity, and the fourth spring is stretched; when the staff releases their hands, due to the elastic force of the second spring, the two handles will automatically separate quickly, and the sliding plug is no longer limited. The elastic force of the fourth spring instantly pulls the sliding plug to slide upward. Due to the characteristic properties of the non-Newtonian fluid, the non-Newtonian fluid in the upper cavity is subjected to an instantaneous impact force, and the non-Newtonian fluid becomes solid, and the sliding plug cannot move upward quickly, so that the sliding plug limits the rotating rod through the connecting rod, and the rotating rod limits the two handles to prevent the two handles from quickly resetting and bouncing onto the operator's hands; then, the sliding plug slowly squeezes the non-Newtonian fluid upward, the sliding plug slowly resets, the rotating rod resets, and the two handles reset.

[0022] Furthermore, a first permanent magnet and a second permanent magnet are fixed on the first handle and the second handle respectively, the first permanent magnet and the second permanent magnet are arranged opposite to each other, and the magnetic poles of the first permanent magnet and the second permanent magnet on the opposite sides are opposite; a coil is arranged inside the rotating rod, and during the rotation of the rotating rod, the coil can cut the magnetic flux lines between the first permanent magnet and the second permanent magnet; the wire stripping part includes a first pliers head and a second pliers head arranged opposite to each other, and a first conductive sheet and a second conductive sheet are fixed on the opposite sides of the first pliers head and the second pliers head respectively; an electromagnet is fixed on the side wall of the cavity, and the electromagnet, the first conductive sheet and the second conductive sheet are all electrically connected to the coil; the sliding plug is a magnet; when a conductor connects the first conductive sheet and the second conductive sheet, the electromagnet, the first conductive sheet and the second conductive sheet form a passage; when the first conductive sheet and the second conductive sheet are separated, the electromagnet, the first conductive sheet and the second conductive sheet form a short circuit.

[0023] When the first and second pliers heads of the wire stripper come into contact with the conductor in the wire, the conductor in the wire can connect the first conductive sheet and the second conductive sheet to form a path; the rotating rod rotates up and down to drive the coil to cut the magnetic flux lines between the first permanent magnet and the second permanent magnet to generate current. Relative to the generator, when a conductor connects the first conductive sheet and the second conductive sheet, the electromagnet, the first conductive sheet and the second conductive sheet form a path, the generator supplies power to the electromagnet, the electromagnet is energized, the electromagnet can absorb the sliding plug to prevent the sliding plug from sliding, and the operator cannot continue to press the two handles, thereby preventing the conductor of the wire from being injured; after the wire is removed, the electromagnet, the first conductive sheet and the second conductive sheet form a short circuit, the electromagnet is powered off, and the sliding plug can slide, thereby preventing the conductor in the wire from being injured.

[0035] The right end of the connecting rod 307 is rotated relative to the handle 100 to realize the folding of the connecting rod 307, and then the fixing rod 304 is pulled to align the fixing hole 308 with the fixing column, and then the fixing rod 304 is loosened, and the third spring 305 pushes the fixing ring 306 and the fixing rod 304 into the fixing hole 308 on the connecting rod 307, so that the connecting rod 307 can be limited, thereby realizing the folding and storage of the wire stripper, so that the volume occupied by the wire stripper when not in use can be reduced, making the wire stripper more portable, which provides convenience for electrical engineering work.

[0036] like Figure 2 As shown, a cylindrical handle 100 is fixed on the fixing rod 304 to facilitate pulling the fixing rod 304 .

[0037] like Figure 5As shown, the handle includes a first handle 101 and a second handle 102 arranged opposite to each other; the buffer mechanism includes a rectangular cavity on the first handle 101, and a rectangular sliding plug 403 is slidingly and sealingly connected inside the cavity, and the sliding plug 403 divides the cavity into an upper cavity 400 and a lower cavity 405, and two through holes 402 are provided on the sliding plug 403, and a non-Newtonian fluid is filled inside the cavity; a first groove 407 is provided on the portion of the first handle 101 located below the cavity, and the first groove 407 is arranged in the vertical direction, and a second groove 411 is provided on the second handle 102, and the first groove 407 and the second groove 411 are arranged in the vertical direction. 1 are arranged relatively, the upper end of the second groove 411 is hinged with a rotating rod 408, the left end of the rotating rod 408 is stuck in the first groove 407 and can slide up and down along the first groove 407; the left part of the rotating rod 408 is hinged with the sliding plug 403 through the connecting rod 404, the connecting rod 404 cannot be deformed, the connecting rod 404 is slidably sealed and connected with the part of the first handle 101 located between the cavity and the first groove 407, the connecting rod 404 can only slide up and down, and a fourth spring 412 is arranged inside the upper cavity 400, the upper end of the fourth spring 412 is fixed to the top of the upper cavity 400, and the lower end of the fourth spring 412 is fixed to the sliding plug 403. A first permanent magnet 406 and a second permanent magnet 409 arranged in a vertical direction are fixed to the left side of the first handle 101 and the right side of the second handle 102, respectively. The first permanent magnet 406 and the second permanent magnet 409 are arranged opposite to each other, and the magnetic poles of the first permanent magnet 406 and the second permanent magnet 406 on the opposite sides are opposite; a coil 410 is arranged inside the rotating rod 408, and during the rotation of the rotating rod 408, the coil 410 can cut the magnetic flux lines between the first permanent magnet 406 and the second permanent magnet 409; the wire stripping part includes a first pliers head and a second pliers head arranged opposite to each other, The first and second conductive sheets are fixed on opposite surfaces of the first and second pliers respectively; an electromagnet 401 arranged in a vertical direction is embedded in the left wall of the cavity, and the electromagnet 401, the first conductive sheet and the second conductive sheet are all electrically connected to the coil 410; the sliding plug 403 is made of iron; when a conductor connects the first conductive sheet and the second conductive sheet, the electromagnet 401, the first conductive sheet and the second conductive sheet form a passage; when the first conductive sheet and the second conductive sheet are separated, the electromagnet 401, the first conductive sheet and the second conductive sheet form a disconnection.

[0038] Non-Newtonian fluids flow when subjected to a slow force, but become hard solids when subjected to a sudden external force.

[0039] When the operator's handle presses the two handles to bring the two handles together, the rotating rod 408 rotates relative to the first groove 407, and the part of the rotating rod 408 located in the first groove 407 slides along the first groove 407. The first groove 407 pulls the sliding plug 403 to slide downward through the connecting rod 404, and the non-Newtonian fluid in the lower cavity 405 enters the upper cavity 400, and the fourth spring 412 is stretched; when the staff releases their hands, due to the elastic force of the second spring 206, the two handles will automatically and quickly separate, and the sliding plug 403 is no longer limited. The elastic force of 12 instantly pulls the slide plug 403 to slide upward. Due to the characteristic properties of the non-Newtonian fluid, the non-Newtonian fluid inside the upper cavity 400 is subjected to an instantaneous impact force, and the non-Newtonian fluid becomes solid, and the slide plug 403 cannot move upward quickly, so the slide plug 403 limits the rotating rod 408 through the connecting rod 404, and the rotating rod 408 limits the two handles to prevent the two handles from quickly resetting and bouncing onto the operator's hands; then, the slide plug 403 slowly squeezes the non-Newtonian fluid upward, the slide plug 403 slowly resets, the rotating rod 408 resets, and the two handles reset.

[0040] When the first and second pliers of the wire stripper contact the conductor in the wire, the conductor in the wire can connect the first conductive sheet and the second conductive sheet to form a path; the rotating rod 408 rotates up and down to drive the coil 410 to cut the magnetic flux lines between the first permanent magnet 406 and the second permanent magnet 409 to generate current. Relative to the generator, when the conductor in the wire connects the first conductive sheet with the second conductive sheet, the electromagnet 401, the first conductive sheet and the second conductive sheet form a path, the generator supplies power to the electromagnet 401, the electromagnet 401 is energized, the electromagnet 401 can absorb the sliding plug 403 to prevent the sliding plug 403 from sliding, and the operator cannot continue to press the two handles, thereby preventing the conductor of the wire from being injured; after the wire is removed, the electromagnet 401, the first conductive sheet and the second conductive sheet form a circuit break, the electromagnet 401 is powered off, and the sliding plug 403 can slide. In this way, the conductor in the wire can be prevented from being injured.

[0041] The specific implementation process is as follows:

[0042] When the second spring 206 needs to be replaced, the sliding block 207 is pressed inward, and the sliding block 207 pushes the fixed block 205 inward to move inward. The fixed block 205 moves inward to shrink the telescopic rod 203 and the first spring 204. At this time, the mounting block 201 loses its limit, and the two mounting blocks 201 together with the second spring 206 can be removed. After the new geothermal spring is installed on the two mounting blocks 201, the mounting block 201 is aligned with the mounting cavity 101 and inserted. The fixed block 205 will move inward and shrink the telescopic rod 203 and the first spring 204. The mounting block 201 is continuously pushed until the telescopic rod 203 and the first spring 204 restore their original lengths, and the fixed block 205 is pushed into the connecting groove 102, and the replacement of the second spring 206 is completed.

[0043] When the wire strippers need to be folded and stored, the right end of the connecting rod 307 is rotated relative to the handle 100 to achieve the folding of the connecting rod 307, and then the fixing rod 304 is pulled to align the fixing hole 308 with the fixing column, and then the fixing rod 304 is released, and the third spring 305 pushes the fixing ring 306 and the fixing rod 304 into the fixing hole 308 on the connecting rod 307, so that the connecting rod 307 can be limited, thereby achieving the folding and storage of the wire strippers.

[0044] During the wire stripping process, when the operator's hands press the two handles to bring the two handles together, the left end of the rotating rod 408 slides downward, and the rotating rod 408 pulls the sliding plug 403 to slide downward through the connecting rod 404, and the non-Newtonian fluid inside the lower cavity 405 enters the upper cavity 400, and the fourth spring 412 is stretched; when the operator releases his hands, the fourth spring 412 resets and instantly pulls the sliding plug 403 to slide upward, and the non-Newtonian fluid in the upper cavity 400 instantly becomes solid, preventing the sliding plug 403 from moving upward quickly, and the two handles cannot be reset quickly, and then, the sliding plug 403 slowly squeezes the non-Newtonian fluid upward, the sliding plug 403 slowly resets, the rotating rod 408 resets, and the two handles slowly reset.

[0045] During the wire stripping process, when the first and second pliers heads of the wire strippers come into contact with the conductor in the wire, the conductor in the wire can connect the first conductive sheet and the second conductive sheet to form a path; the rotating rod 408 rotates up and down to drive the coil 410 to cut the magnetic flux lines between the first permanent magnet 406 and the second permanent magnet 409 to generate current, relative to the generator, the generator supplies power to the electromagnet 401, the electromagnet 401 is energized, the electromagnet 401 can absorb the sliding plug 403 to prevent the sliding plug 403 from sliding, and the operator cannot continue to press the two handles, thereby preventing the conductor of the wire from being injured; after the wire is removed, the electromagnet 401, the first conductive sheet and the second conductive sheet form a short circuit, the electromagnet 401 is powered off, and the sliding plug 403 can slide.

[0046] The above is only an embodiment of the invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the invention, which should also be regarded as the scope of protection of the invention, and these will not affect the effect of the implementation of the invention and the practicality of the patent.
