Abstract

A magnetic gauge stand structurally comprises a base, magnets in an even number, bottom feet, a rotating disk, an upper cover and a handle, wherein the base, the rotating disk and the upper cover are made of non-magnetic material, the bottom feet are made of strong-magnetic material, and the magnets with the upper surfaces and the lower surfaces magnetized are installed in the rotating disk. The magnetic gauge stand has the advantages of being integrated with the base, easy to machine, light in weight and small in switch magnetism angle due to the fact that the ordinary magnets with the upper surfaces and the lower surfaces magnetized are adopted.

Description

Magnetic gauge stand

Technical field

The present invention relates to Magnetic gauge stand, particularly a kind of Magnetic gauge stand.

Background technique

Various measuring tool, miniature instrument etc. are fixed in the common application on platform, the Magnetic gauge stand of the reasonable convenient disassembly again of fixing strength is widely used; Common a kind of Magnetic gauge stand is higher, laterally places one piece of cylindrical radial magnetised magnets, and install the gauge stand main body dimidiation of magnet, centre non-magnet material separates; Another kind of Magnetic gauge stand, with one block of magnetized magnet of cylindrical radial, dimidiation in the middle of base, separates with non-magnet material, also separates with non-magnet material between upper cover and base; The material of main part of two kinds of Magnetic gauge stands is all permeability magnetic material as strong in carbon steel or iron etc., and main body is from middle dimidiation, and weight is large; And magnet is diametrical magnetization, application is few;

Summary of the invention

The object of the invention be to avoid above-mentioned existing Magnetic gauge stand body portion from, weight is large, difficult processing, magnet is the problem of non-generic diametrical magnetization magnet, a kind of Magnetic gauge stand is provided, this Magnetic gauge stand has base one, it is simple, lightweight to process, and adopts the magnetized magnet in common top and bottom, feature that switch magnetic angle is little.

Technical solution of the present invention is as follows:

A kind of Magnetic gauge stand, feature is that its formation comprises base, even number magnet, footing, rotating disk, upper cover and handle, described base, rotating disk and upper cover are that non-magnet material is made, and described footing is that strong permeability magnetic material is made, and the position relationship of above-mentioned component is as follows:

Described base has the also circumference equally distributed multiple base endoporus identical with magnet quantity, and described footing is separately fixed in each base endoporus; Described rotating disk has identical with magnet quantity and circumferential equally distributed rotating disk endoporus, the direction of magnetization of described even number magnet is upper and lower, namely upper and lower surface is S magnetic pole and N magnetic pole, and the magnetic pole of the lower surface of described even number magnet to be arranged in described rotating disk endoporus with adjacent contrary order and to be held up by the thin flange on the lower edge of rotating disk endoporus; The external cylindrical surface of described rotating disk coordinates the rotating machinery of the rotating disk described in forming with the arc surface of described upper cover, described handle and described rotating disk are fixedly linked, described upper cover is fixed together by screw and base, described handle is in the opening between described upper cover and base, pull the described dial rotation described in handle drive, realize switch magnetic.

The upper surface of described footing is more than or equal to the lower surface of magnet, and multiple base endoporus distribution center that the lower surface of described footing has the boss of secundly, described boss to be in described base are in the largest circumference in the center of circle.

Described magnet number is 4,6,8.

The endoporus of rotating disk, the endoporus of base, magnet, footing quantity are all the even number of N(N>=4 mutually), individual, corresponding magnetic switch angle is 180 °/N;

The base one of Magnetic gauge stand of the present invention, need not separate from centre, main body (base, rotating disk, upper cover) is made up of non-magnet material, and adopt common top and bottom magnetised magnets, magnetic switch angle is little, is 180 °/N.

Embodiment

Below in conjunction with accompanying drawing and instantiation, the present invention is further described, but not as a limitation of the invention;

First refer to Fig. 1, stereogram when Fig. 1 is Magnetic gauge stand magnetic force of the present invention unlatching; As shown in Figure 1, now magnetic gauge stand is in opening state, and handle 5 is in the neutral position of upper cover 6 opening;

Stereogram when Fig. 2 is Magnetic gauge stand magnetic force of the present invention closedown; As shown in Figure 2, now magnetic gauge stand is in closed condition, and handle 5 is in the left position of upper cover 6 opening;

As shown in Figure 3, upper cover 6 not magnetic conduction, upper surface has fixing tapped hole 21, and select the size of opening angle a can set Magnetic gauge stand toward an opening/closing frequency during direction rotation, upper cover 6 is directly connected with base 1 by screw 7;

As shown in Figure 4, footing 2 is strong permeability magnetic material, is bonded in base endoporus 16 with glue, and footing boss 15 is as diagram arrangement, and four boss 15 are arranged in outermost circle, to each other apart from maximum;

As shown in Figure 5, rotating disk 4 not magnetic conduction, magnet 4 is blocked by thin flange 10, thus only has disk lower surface 18 to contact with base 1 upper surface 19, blocks when preventing rotating disk 3 from rotating, and reduces accuracy of manufacturing; Fig. 3 is seen with upper cover arc surface 9(in rotating disk cylndrical surface 8) coordinate the rotating shaft forming rotating disk 4; In addition rotating disk cylndrical surface 8 has screw 20(to see Fig. 7) for mounting handle 5; Base plane 13 contacts with foot plane 14 and locates footing 2; Footing upper surface 12 size is identical with magnet lower surface 11, and magnet surface overlaps completely with feet surface, and now Magnetic gauge stand magnetic force is in unlatching;

Magnetic gauge stand is such as shown in Fig. 1, Fig. 5 and Fig. 8 during state, and handle 5 is in upper cover 6 opening neutral position; As shown in Figure 5, now 4 magnet lower surfaces 11 overlap completely with corresponding footing upper surface 12, adjacent magnets 4 magnetic force forms loop by footing boss 15 lower surface and the working platform panel of the magnetic conduction placing Magnetic gauge stand, thus Magnetic gauge stand is adsorbed in working platform, and magnetic force is in opening state; Now, the arrangement state of 4 magnet as shown in Figure 8;

Such as shown in Fig. 2,6 and 9 during state, handle 5 is in the upper cover 6 opening left side, and now 4 magnet lower surfaces 11 overlap with two footing upper surfaces 12 simultaneously; As shown in Figure 6, now magnet 4 magnetic force loop is without the working platform panel of the magnetic conduction of placement Magnetic gauge stand, because every block footing upper surface 12 two ends have two pieces of polarity different magnet 4 overlap, form loop, so now Magnetic gauge stand magnetic force is closed, Magnetic gauge stand separates with working platform panel, does not have suction; Now, the arrangement state of 4 magnet as shown in Figure 9;

If Magnetic gauge stand initial state is as Fig. 2, magnetic force close, do not have suction, then handle 5 rotates 45 °, become as shown in Figure 1 state time magnetic force open, Magnetic gauge stand is adsorbed in working platform, and same direction is rotated further 45 °, then magnetic force is closed again;

Magnet quantity N is got to the even number being greater than 4, change respective seat 1 and rotating disk 3, the switch angle of magnetic force can be made less, when rotating toward a direction, the number of times of switch can be more;
