Description

Magnetic sleeve

This creation is about a sleeve design, especially a magnetic sleeve.

Check, the sleeve is commonly used in the assembly and disassembly of locking components such as bolts, nuts and screws. Whether it is construction, automobile maintenance or furniture assembly, the use of the sleeve is common, but in order to make the lock The locking operation of the component can be carried out quickly, while avoiding excessive shaking of the locking component during the locking process, and solving the problem that in the past when the locking component has a long length, the user must assist in positioning the locking by hand during the locking process The components and the like are missing, so some manufacturers have developed a magnetic sleeve 1 in order to use the magnetic properties of the magnetic sleeve 1 to fix the locking element.

Referring to FIGS. 1A and 1B, the conventional magnetic sleeve 1 includes a sleeve body 11 and a magnetic attraction member 12 disposed in the sleeve body 11; wherein, the sleeve body 11 includes a set of hinges 111, an assembling section 112 opposite to the fitting section 111, a locking hole 113 formed in the assembling section 112, and a connection with the locking hole 113 and corresponding to the size of the magnetic member 12 Mounting hole 114; in view of the fact that the magnetic attraction element 12 is sintered by a powder stamper, which has a hard and brittle texture, if the direct attraction method is used to install the magnetic attraction element 12 in the installation hole 114, It is easy to cause the air in the mounting hole 114 to be unable to be discharged outward, causing the air in the mounting hole 114 to be squeezed to generate a reaction force to push the magnetic attraction element 12, which in turn causes the magnetic attraction element 12 to be compressed Fragmentation occurs. Therefore, a protective material 13 with a softer material is usually coated on the outside of the magnetic element 12, and a plurality of grooves 131 are formed on the periphery of the protective element 13, so the magnetic element 12 is installed During the process, the air in the mounting hole 114 can be discharged outward through the grooves 131 without squeezing the magnetic attraction element 12, however, the arrangement of the protective element 13 not only increases the additional cost, in addition, the magnetic The suction member 12 must be installed in the protective member 13 before the subsequent installation operation can be performed, and the overall processing flow is increased, which is not in line with economic benefits.

In view of this, another manufacturer has developed a magnetic sleeve 2, as shown in FIG. 2A and FIG. 2B, the magnetic sleeve 2 includes a sleeve body 21, and a magnetic suction member disposed in the sleeve body 21 22; wherein, the sleeve body 21 includes a sleeve section 211, an assembly section 212 opposite to the sleeve section 211, a locking hole 213 formed in the assembly section 212, and a lock with the lock A mounting hole 214 communicating with the hole 213 is provided, and the aforementioned mounting hole 214 is composed of six abutment surfaces 2141, and each of the abutment surfaces 2141 extends tangentially along the periphery of the magnetic attraction member 22 and The adjacent abutment surfaces 2141 are in contact so that when the magnetic attraction member 22 is installed in the mounting hole 214, the magnetic attraction member 22 is caught by the abutment surfaces 2141 and creates a gap with the installation hole 214, The air in the mounting hole 214 is discharged outward.

However, after actual use, it is found that the abutment surface 2141 of the mounting hole 214 needs to be precisely matched with the magnetic attraction member 22 to enable the magnetic attraction member 22 to be precisely locked by the abutment surface 2141, but the installation hole The six abutment surfaces 2141 on 214 are directly stamped and formed, which is easy to produce slight dimensional changes during the stamping process, plus the dimensional tolerance of the magnetic attraction member 22, resulting in the magnetic attraction member 22 being installed Can not be caught by the abutment surface 2141, so that the magnetic member 22 can not be firmly fixed and the loss of looseness occurs; if the size of the magnetic member 22 is increased so that the size of the magnetic member 22 is slightly larger than The size of the mounting hole 214 is such that the magnetic attraction member 22 is pressed against the abutment surfaces 2141. During the installation of the magnetic attraction member 22, the abutment surfaces 2141 are prone to cause excessive contact and abrasion of the magnet The suction member 22, and furthermore, the gap formed between the magnetic suction member 22 and the abutment surface 2141 of the mounting hole 214 after installation is too large, so that the magnetic suction member 22 contacts the outside air in a large area to accelerate oxidation, not only As a result, the magnetic decay of the magnetic attraction member 22 is rapidly degraded, which further affects the service life of the magnetic sleeve 2, and excessively large gaps are also likely to accumulate a large amount of metal debris, which indirectly affects the magnetic attraction effect of the magnetic attraction member 22; Therefore, although the conventional magnetic sleeve 2 improves the problem of the protective sleeve 13 added to the previous conventional magnetic sleeve 1, the precise cooperation between the abutment surface 2141 and the magnetic suction member 22 is required, which also causes processing The increased difficulty and the lack of increased production costs need to be improved.

Therefore, the purpose of the present invention is to provide a magnetic sleeve, which effectively avoids the loss of the magnetic suction member being crushed during installation, and at the same time limits the gap between the mounting hole and the peripheral edge of the magnetic suction member to a minimum Space to achieve a stable fixation of the magnetic member.

Therefore, the novel magnetic sleeve includes a sleeve body, and a magnetic suction member disposed in the sleeve body; wherein, the sleeve body includes a set of fitting sections, and an assembly section opposite to the set of fitting sections , A locking hole formed in the connecting section, and a mounting hole communicating with the locking hole, and the aforementioned mounting hole is surrounded by a reference point as a center, and the periphery of the mounting hole is inward At least one latching surface is formed, and the latching surface and the peripheral edge of the mounting hole form two intersections; when the mounting hole is provided with a latching surface, the diameter of the magnetic member is equal to the peripheral edge of the mounting hole passing the reference point to The distance between the latching surfaces, and the joint surface between the two intersections is arranged in an arc shape, and when the mounting hole is provided with at least two latching surfaces, the radius of the magnetic attraction element is equal to the reference point to one of the latching surfaces Distance, and the contact surface between any two clamping surfaces is set in an arc shape; therefore, when installing the magnetic attraction member, the magnetic attraction member is limited by the clamping surface against the top, And cooperate with the peripheral edge of the magnetic suction member and the mounting hole to create a gap for the air to be discharged, and the gap is limited to a minimum space setting, which not only effectively prevents the magnetic suction member from being crushed and crushed during installation, but also avoids the accumulation of metal shavings In the gap, the magnetic attraction effect of the magnetic attraction element is affected, and the magnetic attraction element is stably fixed.
