Abstract
The utility model discloses a magnetic padlock device, which is characterized by comprising a permanent magnet, an attracted part, a screw rod and a screw cap, wherein the screw rod has two ends with different thicknesses, threads are arranged on the thick end and fine end of the screw rod, the permanent magnet is hollow, and round holes are formed in the upper cavity wall and the lower cavity wall of a hollow cavity and are different in sizes; the screw rod having the two ends with different thicknesses and threads penetrates through the large round hole of the permanent magnet and penetrates through the small round hole of the permanent magnet through the fine end of the hollow cavity to be integrated with the screw cap with threads, and the attracted part is a depression and consistent with the permanent magnet in shape. The magnetic padlock device has the beneficial effects of being safe to open and close, firm to combine, and not easy to freely open. The magnetic padlock is safe and practical.
Description
Technical field
The utility model belongs to field of lockset, specifically, relates to a kind of magnetic lock device.
Background technology
It is thousands of year that lockset has been continuous, and it and the mankind's private ownership is almost born simultaneously.Lockset is from its material, shape-designing, mechanical realization, machine-operated structure, painting and calligraphy carved aspects, it relates to multi-door subject, carpentry process, metallurgy and foundry, forge the subjects such as cold-working, fine arts painting and calligraphy, copper woodcarving quarter and power, physics, how much, psychology, can in lockset, find vestige, it has reflected the situation of the aspects such as successive dynasties society and politics, economy, culture, life style and customs.
At first, the mankind just wrap the valuable property of individual simply with animal skin, firmly tie with rope in outside, finally in open place, stamp special knot.Thisly tightly tie dead knot, can only just can choose out with the instrument of " mistake " that cries.Mistake, is again " Xiao ", " cutter ", " bottle opener ".It is made with beast tooth or beast bone, and shape picture is falculate hook, and in fact knot is exactly lockset the earliest, and " mistake " is exactly key the earliest, the blank of Here it is China's lockset.Thisly once be in use to Han dynasty from the Shang dynasty, after use beautiful system instead, develop into baldric on noble's dress ornament along with the progress in epoch, the development of lockset is very fast.On body, in surfacing, in structure, in function, in material application, all to have the development of leap.Various professional with lock arise at the historic moment.Style, kind emerge in an endless stream, thereby make lockset occupy extremely important status in hardware products, security personnel's goods industry.Lockset on case and bag develops like this.Now, along with the raising of people's aesthetic standard, more and more higher to the requirement of the various pattern of case and bag, and then the requirement of lockset is had higher requirement.In order to meet people's demand, magnetic key operated lock arises at the historic moment.The main member of magnetic key operated lock is neodium magnet, neodium magnet (Neodymium magnet), also referred to as ndfeb magnet, is the general designation of strong magnets, and its chemical formula is Nd2Fe14B, a kind of artificial permanent magnet, for to thering is so far the permanent magnet of strong magnetic force.This magnetic key operated lock is not only attractive in appearance, and volume is little, and easy to use.At present, magnetic lock on market is nearly all comprised of the part that can produce the magnetic patch of magnetic force and can be adsorbed, insecure but even this lockset magnetic force is very greatly also locked, in active procedure or in crowded process, all can be opened, so very dangerous.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of magnetic lock device, this device not only opens and closes conveniently, and in conjunction with firmly, is not easy freely to open.
For achieving the above object, the utility model provides following technical scheme: a kind of magnetic lock device, described magnetic lock device comprises permanent magnet, be attracted part, two ends thickness differs and butt end and taper end all screwed screw rod and nut, described permanent magnet is that upper and lower cavity wall hollow and cavity has respectively a circular hole, described circular hole is relative and not of uniform size, described two ends thickness differ and butt end and taper end all screwed screw rod through permanent magnet big hole, by cavity taper end, pass permanent magnet small sircle hole and be integral with screwed nut block, the described part that is attracted is for depression and consistent with permanent magnet shape.
As a kind of improvement of the utility model, the length that the taper end of described screw rod is removed the end of screw thread is at least greater than butt end reach and cavity height, cavity wall thickness, is attracted segment thickness sum, the length of butt end screw thread is less than or equal to the height of cavity, for easy for installation, the utility model length need guarantee above length.
The beneficial effects of the utility model are: it is convenient not only to open and close, and in conjunction with firmly, is not easy freely to open.Safety, practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
the specific embodiment
Below with reference to specific embodiment, technical scheme provided by the invention is described in detail, should understands the following specific embodiment and only for the present invention is described, is not used in and limits the scope of the invention.
The utility model improves a kind of magnetic lock device as shown in Figure 1, described magnetic lock device comprises permanent magnet 1, be attracted part 2, two ends thickness differs and butt end and taper end all screwed screw rod 4 and nut 7, described permanent magnet 1 has respectively a circular hole for upper and lower cavity wall hollow and cavity 3, described circular hole is relative and not of uniform size, described two ends thickness differ and butt end and taper end all screwed screw rod 4 through permanent magnet 1 big hole 5, by cavity 3 taper ends, pass permanent magnet 1 small sircle hole 6 and form one with screwed nut 7, the described part 2 that is attracted is for depression and consistent with permanent magnet 1 shape, the length that the taper end of described screw rod 4 is removed the end of screw thread is at least greater than butt end reach and cavity 3 height, cavity 3 wall thickness, be attracted segment thickness sum, the length of butt end screw thread is less than or equal to the height of cavity 3, for easy for installation, the utility model length need guarantee above length.
The above is the specific embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
