Description

magnetic sleeve

【Technical field】

The invention relates to a sleeve, in particular to a magnetic sleeve with reliable magnetic attraction effect and not easy to drop.

【Background technique】

In view of the fact that although the general sleeve has the function of disassembling and locking the screw head and nut, it is limited by working environment factors such as deep or narrow space, which often leads to loose screw heads, nuts, screws, bolts, etc. , It is a defect that falls inside the tool and is not easy to pick up. Therefore, in order to improve work efficiency, there is a magnetic sleeve.

As shown in Figure 1, Taiwan Patent Publication No. 414133 discloses a magnetic sleeve 1, which includes a sleeve body 12 with a groove 11, an insulator 13, and a sleeve that is sheathed inside the insulator 13 and slightly A magnetic component 15 protrudes from an outer end surface 14 of the insulator 13 .

As shown in FIG. 2 , US Patent No. 5,146,814 discloses a magnetic sleeve 2 that can be disassembled according to the size of the sleeve. It includes a hollow sleeve body 21 and an insulating layer 22 placed inside the sleeve body 21 . And a magnetic component 23 fixed on the bottom of the insulating layer 22 .

As shown in Figure 3, U.S. Patent No. 5,542,320 further discloses a magnetic sleeve 3 that can prevent magnetization, including a hollow sleeve body 31, an insulating block 32, and an insulating block 32 covered The magnetic component 33 is in a space 321 , and an outer end surface 331 of the magnetic component 33 is formed with an insulating thin layer 34 protruding from the lower end surface 332 of the insulating block 32 .

The above-mentioned three kinds of magnetic sleeves 1, 2, and 3 all disclose a function of using magnetic components to achieve the function of absorbing and disassembling components. However, as shown in FIG. 4, taking the third conventional magnetic sleeve 3 as an example, in fact In the past, various magnetic sleeves all had the following problems, that is, when loading and unloading a nut 37, if the length of a screw 38 or bolt on it was too long, although the sleeve body 31 with a longer size could be replaced, in order to increase High sleeve length I, to achieve the purpose of loading and unloading, but, but cause the magnetic suction range of magnetic assembly 33 to be less than nut 37 places, and can't effectively absorb nut 37, therefore, when in deeper or narrower working environment When doing actions such as loading and unloading the nut 37, although the purpose of loading and unloading can be achieved, the magnetic element 33 cannot be used to absorb and take out the nut 37, which causes the nut 37 to fall and be difficult to pick up.

【Content of invention】

【Detailed ways】

As shown in Fig. 5 and Fig. 6, the preferred embodiment of the magnetic sleeve 4 of the present invention comprises a sleeve body 5, an insulator 6 arranged inside the sleeve body 5, and several screws for adsorption. Head 7 (see Fig. 7) and a magnetic part 9 of a nut 8 (see Fig. 8).

As shown in Fig. 5 and Fig. 7, the sleeve body 5 has an upper end face 51 and a lower end face 52 opposite to each other for connecting a tool 10 (hand tool or pneumatic tool), and from the upper end face 51 downwards The end surface 52 extends and passes through a central hole 53 along a central axis. The central hole 53 also has a step 54 close to the upper end surface 51. The bottom of the step 54 is surrounded by an inner wall 55 of the central hole 53 to define a set. Space 56.

The insulator 6 is made of plastic material, is detachably installed in the sleeve space 56 of the sleeve body 5, and has an upper end surface 61 and an upper end surface 61 connected to the step 54 opposite to each other.

The lower end surface 62 , a through hole 63 extending from the upper end surface 61 to the lower end surface 62 along the central axis, and two accommodating grooves 64 extending from the lower end surface 62 toward the upper end surface 61 . The insulator 6 further has an outer slope 65 extending gradually from the periphery of the upper end surface 61 toward the periphery of the lower end surface 62 (see FIG. 6 ).

These magnetic parts 9 are a magnet, and have an inner end face 91 and an outer end face 92 opposite to each other, these magnetic parts 9 are implanted from an open end 66 of these accommodation grooves 64 and make the inner end 91 is connected to a closed end 67 , and its outer end surface 92 is extended in the receiving grooves 64 .

As shown in FIG. 7 , when the mounting and dismounting component is the screw head 7 , the magnetic sleeve 4 can be easily placed on the top of the screw head 7 by the magnetic sleeve 4 through the auxiliary operation of the tool 10 . The magnetic parts 9 are directly in contact with the screw head 7, so after the screw head 7 is loosened by rotation, the magnetic attraction effect of the magnetic parts 9 can be used to suck up the screw head 7 and take it out. Therefore, When in a deep or narrow working environment, the screw head 7 can be effectively taken out by magnetic suction without falling off.

As shown in Fig. 8, when the assembly and dismounting assembly is the nut 8, the magnetic sleeve 4 can also be easily placed on the top of the nut 8 by the magnetic sleeve 4 through the auxiliary operation of the tool 10, At this time, even if the nut 8 is locked on a screw 81, when the locking is completed and the length of the screw 81 beyond the surface of the nut 8 is too long, the screw 81 can temporarily penetrate into the through hole of the insulator 6 63 to make the magnetic parts 9 directly contact with the nut 8, so after the nut 8 is gradually loosened through rotation, the screw 81 is also gradually released from the through hole 63 relative to the insulator 6. Waiting for the magnetic attraction effect of the magnetic part 9, the nut 8 is sucked up and taken out. Therefore, when in a deep or narrow working environment, the nut 8 can be effectively magnetically taken out without falling .

As shown in Figure 9, in addition, another embodiment of the magnetic sleeve 4 is different from the above-mentioned embodiment in that the accommodating groove 64 of the insulator 6 is made into a connection between its lower and upper end surfaces 61, 62, and the magnetic piece 9 can be implanted in the through accommodating groove 64, so that the screw head 7 or the nut 8 can be assembled and unloaded with the auxiliary operation of the tool 10 (see FIG. 8 ), and the The functions and purposes of the above-mentioned embodiments are the same and will not be further described.

It can be seen from the above description that the advantage of the magnetic sleeve of the present invention is that, due to the magnetic sleeve 4 of the present invention, when the screw head 7 is to be assembled and disassembled, the magnetic parts 9 can be directly connected with the magnetic parts 9 after the auxiliary installation and disassembly operation of the tool 10. The screw head 7 is magnetically attracted. When the nut 8 is to be loaded and unloaded, and the protruding screw rod 81 is too long, it can temporarily penetrate into the through hole 63 of the insulator 6 during use, so that the magnetic parts 9 can be directly Contact with the nut 8 and attract each other. After the loading and unloading action is completed, the screw head 7 and the nut 8 can be easily magnetically attracted and taken out. Therefore, compared with the existing magnetic sleeve, it cannot effectively absorb the nut. The lack of the device, the present invention is simple and easy to use and can achieve the desired effect.
