Abstract

The utility model discloses a hang lock with magnetic suction type protection device, which comprises a lock core, a lock body, a lock beam and a key, wherein the lock core is inwardly retracted at a certain distance, a magnetic ball is arranged on exposed face of the lock core, the lock body is provided with a concaved part corresponding to the lock core, a closing cover that shield the whole exposed face of the lock core is sucked in the concaved part by the magnetic ball, the handle of the key is equipped with a magnetic ball for taking the closing cover out, as the closing cover of the hang lock is sucked by the magnetic ball, unless suction force is applied, the closing is difficult to be taken down by hands or other tools, the user only needs to use the magnetic ball on the key to suck the closing cover during normal use so as to perform opening or closing operation, the utility model is very convenient, safe and reliable for application.

Description

The padlock that has magnetic-type lock core protective device

Technical field

The utility model relates to a kind of padlock, a kind of more precisely padlock that has magnetic-type lock core protective device.

Background technology

At present, well-known padlock generally is made up of lock core, lock body, lock bridge and turned parts key, and lock core is as important structure that embodies padlock security performance aspect and the restriction of protector owing to technology or structure, outside generally all being exposed to, tangible origin of force is provided for unlatching of lawless person's technical application or violence damage, thereby brought potential safety hazard for user's use, in dust storm area relatively, also can enter lock core inside and make work such as pellet shot from a slingshot in the lock core malfunctioning and make lock scrap or influence use because of sand and dust.

The utility model content

At the deficiency that existing padlock exists, the purpose of this utility model is to provide a kind of padlock that has magnetic-type lock core protective device.The protective device of this padlock can effectively be protected lock core, lock core is not exposed.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of padlock that has magnetic-type lock core protective device; comprise lock core, lock body, lock bridge and key; the inside indentation certain distance of described lock core; on its exposed face magnetic bead is installed; lock body is provided with and the corresponding recess of lock core; be adsorbed with the capping that the lock core exposed face is all covered by magnetic bead in the recess, the magnetic bead that is used to take out capping is installed on the handle of key.

The size of described recess, shape and capping match.

Described recess and capping are all rounded.

The diameter of described recess and capping is than the big 0.5～2mm of lock core.

Described capping is iron plate or steel disc.

Unless the capping of this padlock is held the back by magnetic bead and with suction its suction evolution can be taken off, otherwise be difficult to get rid of or stick up with other instrument with hand, when normally using, the user only need inhale capping down with magnetic bead on the key, can open or locking work, use very convenient, safe, reliable.

Description of drawings

Fig. 1 is a partial schematic sectional view of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

Description of reference numerals is as follows:

1---lock core 2---lock body

3---lock bridge 4---key

5,5 '---magnetic bead 6---cappings

As shown in Figure 1; this padlock is mainly by lock core 1; lock body 2; lock bridge 3 and key 4 are formed; lock core 1 inside indentation certain distance; a little magnetic bead 5 is installed on its exposed face; lock body is provided with and lock core 1 corresponding recess; suction adsorption by magnetic bead 5 in the recess has capping 6; the lock core exposed face is all covered; thereby lock core is implemented effectively protection; the size of capping 6; shape and recess kissing, all rounded, diameter is than the big 0.5～2mm of lock core; the user only needs can normally open with the 5 ＇ sucking-off cappings 6 of the magnetic bead on the key 4 when opening, and various patterns of capping front Pasting or trade mark increase aesthetic feeling.Certainly, capping 6 is not limited to circle, also can be polygon or other suitable shapes, as long as its thickness can embed recess fully under the prerequisite of guaranteed strength.

The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; though but on its shape or structure, do any variation, every identical with the utility model or akin technical scheme is all within its protection domain.
