Technical Field

The invention relates to the field of small tools with magnetism, in particular to a magnetic rod.

Background

When various vehicles and machines are subjected to fault maintenance, the phenomenon that iron block scrap iron falls into the bottom of a gear box due to various reasons such as gear breakage, bearing scattering and the like is often encountered, if the iron block scrap iron falling into the bottom of the gear box is taken out without the help of tools, all gear parts in the middle gear box need to be completely disassembled, and the trouble of time and labor is too much to do. Therefore, in this situation, the mechanic generally attaches the iron block iron filings on the bottom of the gear box by inserting the magnetic rods into the gaps between the staggered gear slots in the gear box. The magnetic rod in the prior art is formed by connecting the front end of the micro-elastic steel wire strip with the conical magnet, and because the gaps among the gears which are arranged in the gear box in a staggered mode are complex, the magnetic head of the traditional magnetic rod which is not easy to pass through the gaps among the gears which are arranged in the gear box in a staggered mode does not have flexible deformation performance, the traditional magnetic rod can adsorb iron block scrap iron at the bottom of the gear box, and the process is not satisfactory.

Disclosure of Invention

The invention aims to provide a magnetic rod which can flexibly change the direction of the iron block scrap iron falling into the bottom of a gear box to adsorb and clean the iron block scrap iron and can adsorb the iron block scrap iron in a maximized area. The magnetic rod consists of a control handle, a ladle extension line, a turning spring and a magnetic suction head.

The control handle is a handle part of the magnetic rod, the rear part of the control handle is a main handle, the front part of the control handle is an auxiliary handle, the outer diameter of the rear half part of the main handle corresponds to the outer diameter of the auxiliary handle, the outer diameter of the front half part of the main handle is slightly smaller than the inner diameter of the auxiliary handle, the front half part of the main handle and the auxiliary handle are of a primary-secondary structure, and a front cover body of the front half part of the main handle is provided with a screw thread for connecting an inner core stay wire of a. A steel ladle extension line fixing bolt hole is arranged on the cover body at the front end of the auxiliary handle.

The ladle extension line is structurally equivalent to a hand brake line of an electric two-wheel vehicle or a bicycle, and comprises a hollow outer covering line with micro elasticity and an inner core pull line, and fixing bolts are arranged at two ends of the hollow outer covering line.

The turning spring is an annular spring, the length of the turning spring is preferably three to five centimeters, the bottom end of the turning spring is connected to the upper end of the hollow outer covering wire of the ladle extension wire, and the upper end of the turning spring is connected to the lower end of the magnetic suction head.

The magnetic suction head is a round table-shaped strong magnetic suction head, and the middle part of the end surface of the small head at the bottom end of the magnetic suction head is connected with the upper end of an inner core stay wire of the ladle extension wire.

Detailed Description

In the embodiment of the magnetic rod of the invention, as shown in figure 1, the magnetic rod consists of a control handle 1, a ladle extension line 2, a direction-changing spring 4 and a magnetic suction head 5. As shown in fig. 1 and 2, the control handle 1 is a handle part of a magnetic rod, the rear part of the control handle is a main handle 11, the front part of the control handle is a 12-pair handle, the outer diameter of the rear half part of the main handle 11 corresponds to the outer diameter of the sub-handle 12, the outer diameter of the front half part 111 of the main handle 11 is slightly smaller than the inner diameter of the sub-handle 12, the front half part 111 of the main handle 11 and the sub-handle 12 are of a snap-in structure, and a screw thread 112 for connecting an inner core stay wire 3 of a ladle extension wire 2 is arranged on a front; as shown in fig. 1, a fixing bolt hole 121 of the ladle extension line 2 is arranged on the cover body at the front end of the auxiliary handle 12; as shown in fig. 1, the ladle extension line 2 is composed of a hollow outer covering line 21 and an inner core pull line 3, and fixing bolts are arranged at two ends of the hollow outer covering line 21; as shown in fig. 1, the diversion spring 4 is a ring spring, the length of the diversion spring is preferably three to five centimeters, the bottom end of the diversion spring is connected with the upper end of the hollow outer covering wire 21 of the ladle extension wire 2, and the upper end of the diversion spring 4 is connected with the lower end of the magnetic suction head 5; as shown in figure 1, the magnetic suction head 5 is a round table-shaped strong magnetic suction head, and the middle part of the end surface of a small head at the bottom end of the magnetic suction head is connected with the upper end of an inner core pull wire 3 of a ladle extension wire 2.

When the magnetic rod is used, the magnetic rod extends into the bottom of the gear box along the gaps among the gears which are staggered in the gear box, the rear half part of the main handle is held by the rear palm part of a hand, then the rear part of the auxiliary handle is pinched and pushed forwards by a thumb and a forefinger, at the moment, an inner core pull wire connected with a ladle extension wire on a front cover body of the front half part of the main handle generates a pulling force on the magnetic suction head, a ladle extension wire connected with a cover body at the front end of the auxiliary handle generates a pushing force on a direction-changing spring connected with the top end of the steel extension wire, and the direction-changing spring deforms and turns under the acting force of the types of the magnetic. In the practical operation process, the handle can be rotated, and the main handle and the auxiliary handle can be repeatedly pushed and pulled, so that the repeated direction change of the direction change spring is realized, and finally the purpose of adsorbing iron block scrap iron falling into the bottom of the gear box in the largest area of the magnetic suction head is achieved.
