Description

Technical Field

[0001] The present invention relates to the technical field of construction tools, and more particularly to a magnetic socket wrench and a method of using the same. Background Art

[0002] During the steel structure foundation construction phase, for the on-site construction of the pedestal foundation for embedded column foot nodes, the steel column foot is installed by fastening nuts and anchor bolts. However, due to the size limitations of the pedestal foundation, some pedestals with deep depth and small planar dimensions are too close to the pedestal sidewalls after the steel column foot is installed. In addition, due to the space occupied by the stiffening column stirrups or steel cage, personnel cannot enter the pedestal to tighten the anchor bolt nuts, posing operational safety risks and potential project quality hazards. When using ordinary extended sleeves to install nuts, the nuts are easily dropped due to their own weight during the process of being lowered from the top of the pedestal to the anchor bolt position, making them difficult to connect and install. Summary of the Invention

[0003] In view of the above problems, the purpose of the present invention is to provide a magnetic socket wrench and a method of using the same, which is used to install nuts on bolts in a narrow space where people cannot use ordinary wrenches to install. The installation is convenient and stable, thereby improving construction efficiency.

[0004] The present invention provides a magnetic socket wrench, comprising a socket and a magnetic rod arranged in the socket, wherein:

[0005] The sleeve includes an internal threaded tube and an internal hexagonal tube connected to the lower end of the internal threaded tube, and handles are respectively provided on both sides of the upper end of the internal threaded tube, and the handles are perpendicular to the internal threaded tube;

[0007] The inner diameter of the internal threaded tube is the same as the inscribed circle diameter of the internal hexagonal tube, and the length of the internal threaded tube is not less than 50 cm.

[0008] The depth of the hexagonal inner tube is not less than the thickness of the nut to be installed.

[0009] The length of the adjusting rod is not greater than the length of the internally threaded tube, and the sum of the lengths of the adjusting rod and the permanent magnet rod is greater than the length of the internally threaded tube.

[0011] The permanent magnet rod includes NdFeB-40H circular magnetic blocks connected in sequence.

[0012] The external thread of the adjusting rod is a trapezoidal thread, which is arranged at the lower end of the adjusting rod and has a pitch of 2 mm.

[0013] The adjusting rod is provided with a gear line, and the gear line includes a high gear line, a middle gear line, and a low gear line marked from top to bottom along the outer wall of the adjusting rod;

[0014] When the high-speed position line is flush with the upper end of the internally threaded tube, the suction force of the permanent magnet rod on the nut to be installed is (15-25)N;

[0037] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Example 1

[0039] Figure 1 This is a structural schematic diagram of a magnetic socket wrench according to Example 1 of the present invention; Figure 2 Schematic diagram of the structure of a sleeve according to Example 1 of the present invention; Figure 3 Schematic diagram of the structure of the magnetic rod according to embodiment 1 of the present invention;

[0040] like Figure 1-Figure 3 As shown together, the magnetic socket wrench proposed in this embodiment can be used to install nuts on embedded bolts in narrow spaces that cannot be entered by personnel or ordinary wrenches, and can also be used to install nuts on bolts in other narrow and long spaces.

[0041] The magnetic socket wrench comprises a socket 1 and a magnetic rod 2 arranged in the socket 1. The magnetic rod 2 can move in the socket 1 to magnetically attract and release a nut to be installed that is fixed at the lower end of the socket 1.

[0042] To allow the magnetic rod 2 to move and position within the sleeve 1, the sleeve 1 includes an internally threaded tube 11 and an internal hexagonal barrel 12 connected to the lower end of the internally threaded tube 11. The outer end of the internal hexagonal barrel 12 is used to engage the nut to be installed. The threads within the internally threaded tube 11 are screwed together with the external threads on the magnetic rod 2, allowing the magnetic rod 2 to move within the internally threaded tube 11, thereby moving the magnetic rod 2 closer to or further away from the nut to be installed within the internal hexagonal barrel 12. The magnetic force exerted by the magnetic rod 2 on the nut to be installed varies with the distance between the magnetic rod 2 and the end of the internal hexagonal barrel 12. The closer the magnetic rod 2 is to the end of the internal hexagonal barrel 12, the stronger the magnetic force exerted on the nut to be installed. The farther the magnetic rod 2 is from the end of the internal hexagonal barrel 12, the weaker the magnetic force exerted on the nut to be installed. The distance between the magnetic rod 2 and the end of the internal hexagonal barrel 12 can be adjusted according to specific construction needs.

[0043] In order to facilitate the use of the sleeve 1, handles 3 are respectively provided on both sides of the upper end of the internally threaded tube 11. The handles 3 are perpendicular to the internally threaded tube 11 and are on the same straight line. The handles 3 can be made of steel rods.

[0044] To facilitate magnetic attraction, the magnetic rod 2 includes an externally threaded adjustment rod 21. A permanent magnet rod 22 is connected to the lower end of the adjustment rod 21, and a hexagonal nut 23 is provided at the upper end of the adjustment rod 21. The adjustment rod 21 is screwed into the internally threaded tube 11, and the permanent magnet rod 22 magnetically attracts the nut to be installed within the internal hexagonal tube 12. The external threads on the adjustment rod 21 are compatible with the internal threads of the internally threaded tube 11, allowing for screwing therewith. The permanent magnet rod 22 is used to generate a magnetic attraction force to magnetically attract the nut to be installed. The hexagonal nut 23 at the upper end of the adjustment rod 21 facilitates the use of a conventional wrench to rotate the adjustment rod 21 within the internally threaded tube 11.

[0045] In a specific embodiment of the present invention, the inner diameter of the internal threaded tube 11 is the same as the inscribed circle diameter of the internal hexagonal tube 12. In this way, the inner diameter of the internal threaded tube 11 must be larger than the inner diameter of the nut to be installed. The internal threaded tube 11 can accommodate the upper end of the embedded bolt of the nut to be installed, making it easier for the sleeve 1 to screw the nut to be installed into place.

[0046] The length of the internal threaded tube 11 is not less than 50 cm. The length of the internal threaded tube 11 should be longer than that of an ordinary socket wrench so as to be suitable for operation in a relatively narrow space.

[0047] In a specific embodiment of the present invention, in order to stably secure the nut to be installed, the depth of the hexagonal inner tube 12 is not less than the thickness of the nut to be installed, and the hexagonal inner tube 12 can secure nuts of different lengths.

[0048] In a specific embodiment of the present invention, the length of the adjusting rod 21 is not greater than the length of the internal threaded tube 11, the sum of the lengths of the adjusting rod 21 and the permanent magnet rod 22 is greater than the length of the internal threaded tube 11, the permanent magnet rod 22 is coaxial with the adjusting rod 21, and the outer diameter is smaller than the diameter of the inscribed circle of the inner hexagonal tube 12. The length of the adjusting rod 21 can be less than or equal to the length of the internal threaded tube 11, so that it is easy to screw with the internal threaded tube 11 and adjust the suction force of the permanent magnet rod 22 on the nut to be installed. The length and magnetic force of the permanent magnet rod 22 can be selected according to specific magnetic attraction needs. The sum of the lengths of the adjusting rod 21 and the permanent magnet rod 22 can be greater than the length of the internal threaded tube 11. The permanent magnet rod 22 can be inserted into the inner hexagonal tube 12 to ensure sufficient suction force on the nut to be installed.

[0049] In one embodiment of the present invention, the permanent magnet rod 22 may comprise a series of connected NdFeB-40H circular magnets. The circular magnets are selected with an appropriate magnetic force and radius, depending on the specific situation, to form a permanent magnet rod 22 that can stably attract the nut to be installed. In this embodiment, the magnetic force of the permanent magnet rod 22 can be 30N. The magnetic force should be moderate, ensuring stable attraction and allowing the permanent magnet rod 22 to release the nut after moving upward a certain distance.

[0050] In one embodiment of the present invention, to facilitate adjustment of the magnetic force, the external thread of the adjustment rod 21 is a trapezoidal thread. This thread is located at the lower end of the adjustment rod 21, while the internally threaded tube 11 is fully threaded. This trapezoidal thread allows the adjustment rod 21 to move up and down within the internally threaded tube 11. Simply providing a trapezoidal thread no shorter than 5 cm at the lower end of the adjustment rod 21 ensures a stable screw connection. The trapezoidal thread has a pitch of 2 mm, and setting this pitch appropriately allows for fine-tuning of the magnetic attraction of the nut to be installed.

[0051] In a specific embodiment of the present invention, in order to facilitate the control of the magnetic attraction, a gear line is provided on the adjustment rod 21, and the gear line includes a high gear line, a middle gear line, and a low gear line marked from top to bottom along the outer wall of the adjustment rod 21. When the high gear line is flush with the upper end of the internal threaded tube 11, the permanent magnet rod 22 is closest to the nut to be installed in the inner hexagonal tube 12, and the magnetic attraction force on the nut to be installed is the strongest, and the nut to be installed can be stably sucked into the inner hexagonal tube 12; when the middle gear line is flush with the upper end of the internal threaded tube 11, the magnetic attraction force on the nut to be installed is weakened, and it can be used for adjustment when the nut to be installed has just been screwed onto the embedded bolt; when the low gear line is flush with the upper end of the internal threaded tube 11, there is almost no magnetic attraction on the nut to be installed, and the permanent magnet rod 22 has also moved to the upper half of the internal threaded tube 11, and the nut to be installed can be further screwed onto the embedded bolt.

[0052] The positions of the high-speed position line, the mid-speed position line, and the low-speed position line are set according to specific circumstances. Specifically, when the high-speed position line is flush with the upper end of the internal threaded tube 11, the permanent magnet rod 22 exerts a suction force of (15-25) N on the nut to be installed in the internal hexagonal tube 12, which can stably attract the nut to be installed and prevent it from falling out of the internal hexagonal tube 12; when the mid-speed position line is flush with the upper end of the internal threaded tube 11, the permanent magnet rod 22 exerts a suction force of (8-12) N on the nut to be installed in the internal hexagonal tube 12, which can attract the nut to be installed, but the suction force is not strong; when the low-speed position line is flush with the upper end of the internal threaded tube 11, the permanent magnet rod 22 has a suction force of ≤3 N on the nut to be installed in the internal hexagonal tube 12, which can hardly attract the internal hexagonal tube 12 at this time.

[0053] Some narrow spaces are relatively dark. In a specific embodiment of the present invention, a lighting lamp facing downward is provided on the outer wall of the internally threaded tube 11. The lighting lamp can illuminate the narrow space and facilitate observation and operation by personnel.

[0054] The magnetic socket wrench can be manufactured with hexagonal sockets 12 of different specifications, and is suitable for the installation of nuts of different types.

[0055] Example 2

[0056] Figure 4 This is a flow chart of a method for using a magnetic socket wrench according to Example 2 of the present invention;

[0057] like Figure 4 As shown, the method for using the magnetic socket wrench provided in this embodiment uses the magnetic socket wrench described in Example 1 to install a nut in a narrow space, including the following steps:

[0058] S1: Rotate the hexagonal nut 23 to move the permanent magnet rod 22 toward the inner hexagonal cylinder 12 until the nut to be installed in the inner hexagonal cylinder 12 is magnetically attracted.

[0059] Adjust the suction force of the permanent magnet rod 22 on the nut to be installed so that when the permanent magnet rod 22 approaches the nut to be installed, it can stably absorb the nut to be installed, making it convenient for the magnetic socket wrench to be lowered with the nut to be installed onto the embedded bolt in a narrow space.

[0060] S2: Hold the handle 3 and screw the nut to be installed onto the end of the embedded bolt.

[0061] Connect the sleeve 1 to the embedded bolt, and turn the handle 3 to initially screw the nut to be installed onto the embedded bolt.

[0062] S3: Rotate the hexagonal nut 23 to move the magnetic rod 2 away from the inner hexagonal tube 12 until the magnetic attraction releases the nut to be installed in the inner hexagonal tube 12 .

[0063] The nut to be installed has been screwed onto the embedded screw, so there is no need for magnetic attraction. Rotate the magnetic rod 2 upward along the inside of the sleeve 1 and away from the nut to be installed to release part of the magnetic attraction or release all of the magnetic attraction.

[0064] S4: Hold handle 3 and screw the nut to be installed onto the embedded bolt into place.

[0065] After the magnetic rod 2 moves upward along the inside of the sleeve 1, there is a space in the middle of the internal threaded tube, which can accommodate the insertion of the embedded bolt, making it easy to rotate the nut to be installed into place on the embedded bolt.

[0066] The magnetic socket wrench and its method of use according to the present invention are described above by way of example with reference to the accompanying drawings. However, those skilled in the art will appreciate that various modifications may be made to the magnetic socket wrench and its method of use as described above without departing from the scope of the present invention.
