Abstract

The magnetic sleeve includes one sleeve body to define one sleeving space, one insulating part inside the sleeve body, and one magnetic assembly for absorbing one assembling and disassembling module. The detachable insulating part is mounted inside the sleeving space and has one upper end surface and one lower end surface in the opposite direction, one hole through the central axle and several holding grooves extending from the lower end surface to the upper end surface. The magnetic parts are set inside the holding grooves of the insulating part to adsorb screw parts in determined adsorbing effect without falling off.

Description

Magnetic sleeve

[technical field]

The present invention relates to a kind of sleeve, is meant the magnetic sleeve that a kind of magnetic effect is certain and be difficult for dropping especially.

[background technology]

Because though general sleeve has the function of dismounting, locking screw head and nut, but be subject to dark or than working environment factors such as narrow spaces, screw terminal after often causing getting loose, nut, screw rod, bolt etc., drop inner and defective that be difficult for picking up at facility, therefore, in order to promote operating efficiency, a kind of sleeve with magnetic is arranged then.

As shown in Figure 1, the Taiwan patent announcement discloses a kind of magnetic sleeve 1 No. 414133, comprise sleeve body 12, the insulating part 13 with a groove 11, and one is set on the magnet assembly 15 that the inner and dimplings of this insulating part 13 go out an outer face 14 of this insulating part 13.

As shown in Figure 2, United States Patent (USP) the 5th, 146, then disclose for No. 814 a kind of can be in response to the magnetic sleeve 2 of sleeve dimensions dismounting, the sleeve body 21, one that includes a hollow is placed in the insulating barrier 22 of these sleeve body 21 inside, and a magnet assembly 23 that is fixed in these insulating barrier 22 bottoms.

As shown in Figure 3, United States Patent (USP) the 5th, 542, but further disclose a kind of magnetic sleeve 3 of antimagnetizing for No. 320, the sleeve body 31, the collets 32 that include a hollow, and one by this collets 32 space 321 that is coated on magnet assembly 33, an and outer face 331 of this magnet assembly 33 and be formed with and protrude the heat insulating lamina 34 of a lower surface 332 of collets 32.

Above-mentioned three kinds of magnetic sleeves 1,2,3 all disclose a kind of function of utilizing magnet assembly to reach absorption loading and unloading assembly that has, but, as shown in Figure 4, act with the third in the past magnetic sleeve 3 be example, in fact, various in the past magnetic sleeves all have following point, promptly when loading and unloading one nut 37, if the length of screw rod 38 on it or bolt is oversize, though the sleeve body 31 of replaceable longer dimension, so as to increasing length sleeve I, to reach the purpose of loading and unloading, still, the magnetic scope that but causes magnet assembly 33 is not as good as nut 37 places, and can't effectively adsorb nut 37, therefore, when in darker or narrower actions such as working environment do loading and unloading nut 37, though can reach the loading and unloading purpose, but can't utilize this magnetic element 33 with 37 absorption of this nut and take out of, and cause nut 37 to drop and the puzzlement that is difficult to pick up.

[summary of the invention]

The object of the present invention is to provide a kind of magnetic sleeve that nut can be adsorbed really and is difficult for dropping.

In order to achieve the above object, the invention provides a kind of magnetic sleeve, comprise the insulating part that a sleeve body, is arranged on this sleeve body inside, and several magnetic parts, it is characterized in that:

[specific embodiment]

As Fig. 5, shown in Figure 6, the preferred embodiment of magnetic sleeve 4 of the present invention is to comprise the insulating part 6 that a sleeve body 5, is placed in these sleeve body 5 inside, and several can be for the magnetic part 9 of absorption one screw terminal, 7 (see figure 7)s and a nut 8 (see figure 8)s.

As Fig. 5, shown in Figure 7, this sleeve body 5 has reverse each other a upper surface 51 and a lower surface 52 for connection one instrument 10 (hand-held tool or pneumatic tool), and by this upper surface 51 toward lower surfaces 52 centre bores 53 that extend and run through along a central axis, this centre bore 53 also has a class 54 near this upper surface 51, and these class 54 bottoms borrow an inwall 55 of this centre bore 53 around defining a sheathed space 56.

This insulating part 6 is made for plastic material, removably is installed in the sheathed space 56 of this sleeve body 5, and have reverse each other one for the upper surface 61 that is engaged on this class 54 and

One lower surface 62, by this upper surface 61 toward lower surfaces 62 through hole 63, two storage tanks 64 that extend towards these upper surface 61 directions from this lower surface 62 that extend and run through along central axis.And this insulating part 6 has more inclined-plane, the outside 65 (see figure 6)s that increase gradually and extend towards these lower surface 62 peripheries from the periphery of this upper surface 61.

These magnetic parts 9 are a magnet, and have a reverse each other inner face 91 and an outer face 92, these magnetic parts 9 are implanted from an open end 66 of these storage tanks 64 and its inner face 91 are connected on a blind end 67, and 92 of its outer faces are stretched and are located in these storage tanks 64.

As shown in Figure 7, its use is when the loading and unloading assembly is this screw terminal 7, this magnetic sleeve 4 is via the auxiliary operation of instrument 10, just can at an easy rate this sleeve body 5 be nested with at this screw terminal 7 tops, these magnetic parts 9 are directly contacted with this screw terminal 7, so through behind this screw terminal 7 of rotation pine oil, can utilize the magnetic effect of these magnetic parts 9, this screw terminal 7 is picked up and takes out of, so, when being in darker or narrower working environment, unexpected dropping can effectively screw terminal 7 magnetic be taken out.

As shown in Figure 8, and when the loading and unloading assembly is this nut 8, this magnetic sleeve 4 is again via the auxiliary operation of instrument 10, also can at an easy rate this sleeve body 5 be nested with at this nut 8 tops, at this moment, even if these nut 8 lockings are on a screw rod 81, locking is finished and this screw rod 81 exceeds the length on nut 8 surfaces when oversize, 81 of its screw rods can temporarily conceal the through hole 63 that penetrates this insulating part 6, these magnetic parts 9 are directly contacted, so through after rotating gradually this nut 8 of pine oil, this screw rod 81 is this insulating part 6 and deviate from this through hole 63 gradually relatively also with this nut 8, then utilize the magnetic effect of these magnetic parts 9 this moment, this nut 8 is picked up and takes out of, so, when being in darker or narrower working environment, can effectively nut 8 magnetic be taken out, and can not drop.

As shown in Figure 9, in addition, another embodiment of this magnetic sleeve 4, not not existing together of itself and the foregoing description, be the slotted eye of the storage tank 64 of this insulating part 6 being made its upper and lower end face 61,62 of connection, this magnetic part 9 is then implantable in the storage tank 64 that connects, but so just screw terminal 7 or nut 8 (see figure 8)s are loaded and unloaded in the auxiliary operation of engagement tool 10, and reach effect and purpose same as the previously described embodiments, no longer add explanation.

Through the advantage of magnetic sleeve of the present invention as shown in the above description be, because magnetic sleeve 4 of the present invention, when desire is loaded and unloaded this screw terminal 7, can be through behind the auxiliary charge and discharge operations of instrument 10, make these magnetic parts 9 direct and these screw terminal 7 magnetic, when desire loading and unloading nut 8, and when the screw rod that protrudes on it 81 is long, can temporarily conceal in the through hole 63 that penetrates this insulating part 6 during use, impel these magnetic parts 9 directly to contact and absorption mutually with this nut 8, after treating that the loading and unloading action finishes, just can be easily with screw terminal 7, nut 8 magnetic are also taken out of, so, comparing in the past that magnetic sleeve has the disappearance that can't effectively adsorb nut, the present invention is then to install simple and easy to use and can reach the effect of expection.
