Description

Magnetic sleeve

The present invention relates to the technical field of a sleeve, and in particular to a magnetic magnetic sleeve in which a magnetic device is disposed in a sleeve.

Generally, the sleeve can be used to lock or release nuts, bolts, spark plugs and the like. The main structure of the sleeve comprises a sleeve end portion and a sleeve portion at the two ends, wherein the sleeve portion has a polygonal sleeve hole corresponding to the working object specification, and the sleeve portion is formed with a sleeve hole for fitting a suitable driving tool. .

In order to meet the needs and convenience of the work, a magnetic element can usually be mounted in the sleeve hole to magnetically work. For example, Taiwan Patent No. I410306, No. M327772, and No. M429565 disclose that a combination of a magnet holder and a magnet is disposed at one end of the sleeve, so that when the sleeve is moved, the workpiece can move synchronously; however, At this time, the workpiece still protrudes into the sleeve hole for a certain distance, so the extraction is inconvenient.

In order to solve the problem that the workpiece protrudes into the sleeve hole for a certain distance, the Taiwanese Patent No. M459964, the No. M362737 patent and the No. M299621 patent are all disclosed except that the casing is installed in the hole. In addition to the magnetic component, the magnetic component can also be coupled with a spring. When the magnetic component is pushed by the spring, the workpiece can be automatically moved to the port position of the sleeve hole for the operator to take out. It is worth noting that the magnets or magnet holders of the above patents need to correspond to appropriate positioning elements or mechanisms to prevent the magnets from being exposed or dislodged.

The purpose of this creation is to provide an elastic magnetic sleeve which has the advantages of compact structure and convenient assembly.

In order to achieve the above objects and effects, the present invention comprises a magnet holder having an assembly space in the axial direction and an outer surface axially formed with a chute structure; a magnet is mounted in the assembly space of the magnet holder; a spring is mounted In the assembly space of the magnet holder, the spring end abuts against the magnet; the other sleeve body has an accommodating space in the axial direction, and the magnet seat, the magnet and the spring are mounted in the accommodating space. And one end of the spring abuts against the bottom of the accommodating space; a C-shaped buckle is mounted on the inner wall surface of the accommodating space and fits in the chute structure; thus the combination of the magnet seat and the magnet can be accommodated therein The space moves, and the combination of the magnet holder and the magnet is stopped by the C-shaped buckle without coming out of the accommodating space.

Figure 1 is an exploded view of the creation.

Figure 2 is a schematic diagram of the structure of the creation.

Figure 3 is a diagram of the use state of this creation.

Figure 4 is the use state diagram 2 of this creation.

Referring to FIG. 1, the present invention is a combination of a sleeve body 10, a spring 20, a magnet 30, a magnet holder 40 and a C-shaped buckle 50.

Referring to FIG. 2, an axial space is formed in the sleeve body 10 to form an accommodation space. 12, and an annular recess 14 is formed in the inner wall surface of the accommodating space 12. The C-shaped buckle 50 is mounted in the recess 14. The spring 20 is mounted in the accommodating space 12, and one end of the spring 20 abuts against the bottom of the accommodating space 12.

The magnet holder 40 is formed in a cylindrical shape and has an assembly space 42 in the axial direction. A chute structure 44 is formed in the axial direction of the outer peripheral surface of the magnet holder 40. In particular, the two ends of the magnet holder 40 are each formed with a convex ring portion 46 and 48 such that the chute configuration 44 is formed in a concave shape between the convex ring portions 46 and 48 at both ends of the magnet holder 40. The magnet 30 is mounted in the assembly space 42 of the magnet holder 40.

The combination of the magnet holder 40 and the magnet 30 is mounted in the accommodating space 12 of the sleeve body 10. In particular, a portion of the spring 20 extends into the assembly space 42 of the magnet holder 40, and one end of the spring 20 abuts against the magnet 40. And the magnet holder 40 can pass through the central opening of the C-shaped buckle 50, so that the C-shaped buckle 50 fits in the chute configuration 44.

It should be noted that although the C-shaped buckle 50 is located in the slot 14 but still has the ability to elastically open and close, the assembly worker can apply force to pass one end of the magnet holder 40 through the center of the C-shaped buckle 50. The aperture configuration is configured and the C-shaped buckle 50 can be nested in the chute configuration 44. In addition, although the magnet holder 40 is slidable, the C-shaped buckle 50 can abut against the collar portions 46 and 48, so that the magnet holder 40 is restrained from coming out of the accommodating space 12.

Referring to FIG. 3, the user can use the accommodating space 12 of the sleeve body 10 to be combined with a workpiece 60. At this time, the combination of the magnet holder 40 and the magnet 30 moves toward the bottom of the accommodating space 12, thereby further The spring 20 is caused to form a compression shape. Since the C-shaped buckle 50 is fitted in the chute structure 44, the C-shaped buckle 50 and the chute structure 44 can be relatively displaced when the magnet holder 40 moves. Subsequent application of force can be used to tighten or loosen the workpiece 60 by appropriate torque.

Please refer to Fig. 4, taking the work piece 60 as an example, when the user moves the set The barrel body 10 can be attached to the end of the magnet holder 40 by the magnetic force of the magnet 30 and moved away from the original mounting position. Under the restoring force of the spring 20, the magnet holder 40 and the magnet 30 move toward the opening end of the accommodating space 12, thereby simultaneously pushing the workpiece 60 toward the open end of the accommodating space 12, so that The workpiece 60 does not fall off with the movement of the sleeve body 10, and because only a small portion of the workpiece 60 is located in the accommodating space 12 and adjacent to the open end, the user can easily and quickly remove the workpiece 60. The work item 60.

The spring 20, the magnet 30, the magnet holder 40 and the C-shaped buckle 50 are mounted inside the sleeve body 10 according to the present invention, and the structure is simplified, and the combination of the magnet holder 40 and the magnet 30 is only It can be combined with the sleeve body 10 by pressing force, so that it has the convenience of assembling.

The above is a preferred embodiment and a design of the present invention, but the preferred embodiments and the design drawings are merely illustrative and are not intended to limit the scope of the present invention. The scope of the rights covered by the contents of the "Scope of Application for Patent Application" is not within the scope of this creation and is the scope of the applicant's rights.
