Technical Field

The utility model belongs to the technical field of screw disassembling tools, and relates to a wrench, in particular to a novel magnetic wrench.

Background

The method is characterized in that emulsion water and wastewater for cooling, spraying, supporting and pump stations of equipment of a coal mine fully-mechanized mining face are discharged, various pipelines need to be arranged on a top plate of a belt roadway of the fully-mechanized mining face, and in order to keep the safety and standardization of the roadway, the drainage pipeline is usually installed at a position 0.6 m away from the top of the belt roadway and fixed by 10# channel steel and an anchor rod. The drainage pipeline consists of 3 pipes of 4 inches and 3 pipes of 2 inches, wherein the 4-inch pipes are respectively used for drainage, sprinkling and standby, the 2-inch pipes are respectively used for emulsion, sprinkling and forced air, each pipeline is 6 meters long, adjacent pipelines are fixed by a flange plate, 4 or 6 holes are evenly distributed on the flange plate and are connected by M16 bolts. According to the working schedule of a coal mining machine of our company, the coal mining machine is 1.8-2 meters a day, generally, the assembly and disassembly work is carried out once within 2 days, when each bolt is disassembled and assembled, two hands of workers are occupied simultaneously, the two wrenches are matched together, one hand holds one wrench to fix the head of the bolt, the other hand holds the other wrench to screw the nut matched with the nut thread, the operation cannot be strong, the assembly and disassembly of the workers are unsafe and inconvenient due to the fact that the top plate of the working face is too high, the workers cannot grasp the handrail and the like when the bolts and the nuts are screwed, the labor intensity of the workers is increased, and the production schedule of the working face is influenced.

SUMMERY OF THE UTILITY MODEL

The present invention is directed to solve the above problems in the background art, and provides a novel magnetic wrench.

The technical means for solving the technical problems of the utility model is as follows: the utility model provides a novel magnetic force spanner, includes handle, spanner and connects the slope high neck of the two, and handle place plane parallels with spanner place plane, opens on the spanner have with the plum blossom hole of nut or bolt adaptation, has linked firmly on the handle and is in with one side and be used for adsorbing the magnetic part on the metal surface with the spanner, and magnetic part's height equals the difference in height of handle and spanner. The height of the magnetic component is equal to the height difference between the handle and the wrench head, and because the magnetic component and the wrench head are located on the same side, when the wrench head is placed on the plane, the magnetic component is also located on the plane, the lower end face of the magnetic component is flush with the lower surface of the wrench head, the quincuncial holes in the wrench head are clamped with the head of the bolt, under the action of attraction of the magnetic component, the whole magnetic wrench can be adsorbed on the surface of the flange, and after the magnetic wrench is contacted with the pipe wall and clamped, the magnetic wrench can be prevented from rotating, the resistance of magnetic force and the pipe wall to the magnetic wrench is utilized, a worker can unscrew the nut by using a single-hand common wrench, the other free hand can grab a wall surface or some fixed objects, the balance of the worker is ensured, and the disassembling work is completed.

Preferably, magnetic part includes and parallels with the cylindrical sleeve of handle looks welded, cylindrical sleeve's axis and the axis in plum blossom hole, is provided with magnet in the cylindrical sleeve, and embedded countersunk head bolt of installing on the handle, the other end of countersunk head bolt runs through behind handle and the magnet screw-thread fit have the nut that is used for fastening magnet, and nut and countersunk head bolt all do not surpass cylindrical sleeve's tip. Cylindrical sleeve plays the guard action to magnet, can fix the magnet through cylindrical sleeve, countersunk head bolt and nut moreover, and nut and countersunk head bolt do not all exceed cylindrical telescopic tip is in order to guarantee the level and smooth of magnetic part terminal surface.

Preferably, the magnet is of the same height as the cylindrical sleeve, and the end faces of the magnet and the cylindrical sleeve which are in contact with the metal surface are coated with a protective layer. Magnet and cylindrical sleeve are equal height for the terminal surface of magnetic part is level and smooth, guarantees the adsorption effect of magnet, and the structure is more reasonable, and is more preferred, and the protective layer is made by silica gel or plastics. This is because the magnet material is more fragile, in order to protect the magnet not to be knocked for bad, so set up the protective layer, and then guaranteed magnetic spanner's life uses silica gel or plastics to make the protective layer, because silica gel or plastics not only wear-resisting but also light.

Preferably, the magnetic part is made of a whole magnet, and the magnet is fixed on the handle through an adhesive layer, so that the structure is simple, and the manufacturing cost is reduced.

Preferably, the magnet is externally coated with a protective layer made of silicone or plastic. This is in order to protect the magnet not to be collided, prolongs the life of magnetic spanner.

Preferably, the handle, the wrench head and the inclined stem are integrally formed. This is for the magnetic wrench to be more structurally stable.

Preferably, the length of the wrench in the horizontal direction is 60-80 mm. The height of the wrench in the vertical direction is 25-35 mm. The structure is small and exquisite, and the device can be used in a narrow space and is very convenient.

Preferably, the inclined high neck forms an obtuse angle with the handle and the wrench head respectively. The arrangement structure is reasonable.
