Abstract
The utility model discloses a cylinder hole shield structure of lock, which is composed of a covering cap, a covering sheet, a barrier chip contacted by an elastic element and some magnetic pin columns contacted by a little spring. The end face of the lock base of the lock is provided with the barrier chip and the magnetic pin columns, and the barrier chip and the magnetic pin columns are covered by the covering sheet. The covering cap is installed outside the covering sheet. Otherwise, the handle part of the key is provided with a lock-open part with a magnetic body, and the magnetic body is provided with the same magnetic pole as the opposite end of the magnetic pin column. The barrier chip can cover the cylinder hole and be convexly contacted and locked by the magnetic pin column, which makes the key correspondingly dismiss the magnetic pin column with the lock-open part of the handle part. The barrier chip is pushed off by the elastic element and opens the cylinder hole for the inserting or unlocking of the key.
Description
The utility model relates to a kind of lockset, refers to a kind of lock core hole masking device of lockset especially.
Lockset is directed at the keying difficulty for avoiding foreign matter to enter core at present, is at the core place one dust cap to be set mostly, to avoid core G-card sand dust or to get rusty; But the more common people who feels agaainst the law or mischief deliberately plugs sticker or fast Ganlei's viscose glue at the lock core hole of other people vehicle, making the car owner normally insert core with key unblanks, and need from newly changing lock, yet the dustproof cover structure of general lockset seldom is designed to the form of tool Lock structure, is opened arbitrarily by the people and lock core hole is sabotaged so still exist; General burglar has the general-purpose key more, and lockset commonly used can't prevent by its illegal pirate of the open.
The purpose of this utility model provides a kind of lock core hole masking device of lockset, and the masking structure that it can make lock core hole have last locking-type is to reach the effect that two-bolt lock is pulled and protected lock core hole.
For achieving the above object, solution of the present utility model is: the lock core hole masking device of lockset, at least including a block, covers sheet, and has the lock leading section that the catch of flexible member contact and magnetic pin and the structure of little spring composition are located at lockset, and plan a key that is used, wherein the lock front end face forms concave face and groove, and forms irregular appearance hole on the concave face; Block a shot relative lock lock core hole with spread all over the zone that holds the hole and form one and bore a hole and hollow slots; Covering sheet is a lamellar body greater than the lock concave face; Catch is one the vertical press section and the horizontal lamellar body of shielding portion to be arranged, its shielding portion one end butt flexible member, and end extends suitable long corresponding appearance hole at lock in addition; The magnetic pin is the magnetic that two ends are positive-negative polarity; The portion that undoes the lock of body and the corresponding block hollow slots shape of being magnetic in establishing on the key, end face in opposite directions of magnetic and magnetic pin is a same pole in this; Catch is kept out flexible member with its shielding portion and is opposed at lock concave face and groove, the magnetic pin is to meet the Rong Kongzhong that little spring is installed with at lock in the positive and negative extreme form outwardly of any difference, cover butt sheet and magnetic lock to cover sheet, the block noose is on lock.
After adopting such scheme; because catch is to protrude out to ending locking with the magnetic pin when hiding lock core hole; when using key opposed during in the block hollow slots with the shank portion that undoes the lock; undo the lock magnetic in the portion and magnetic pin just making contracting in the magnetic pin with the same sex effect of repelling each other and no longer supports static joining-pin; thereby make catch automatically springed open by the flexible member pushing and pressing; open for key is slotting to open lock core hole, and reach the effect that two-bolt lock is pulled and protected lock core hole.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the combination lock of the present utility model schematic diagram () of pulling;
Fig. 3 is the combination lock of the present utility model schematic diagram (two) of pulling;
Fig. 4 is the view that undoes the lock of the present utility model ();
Fig. 5 is the view that undoes the lock of the present utility model (two).
At first, see also shown in Figure 1, when the utility model is used in the main switch lock of general locomotive, main with the leading section of structural planning of the present utility model at its lock 1, include a block 2, and cover catch 4 and the some magnetic pins 6 and little spring 7 that sheet 3, has flexible member 5 contacts, and establish a key that is used 8; Wherein:
Lock 1 front end face forms a concave face 11 and a groove 12, and the appearance hole 13 of the some irregular alignments of moulding on the concave face 11;
Block 2 relative locks 1 lock core holes 14 with spread all over the zone that holds hole 13 and form one and bore a hole 21 and hollow slots 22;
Covering sheet 3 is L matrix bodies of generally relative lock 1 concave face 11;
Catch 4 is inverted T shape lamellar bodies of vertical press section 41 of a tool and horizontal shielding portion 42, and its shielding portion 42 1 ends form a convex body 421 and support for elasticity element 5 covers, and other holds 13 positions, appearance hole of corresponding lock 1 to form rabbet 422 at upper limb;
The portion that undoes the lock 81 of key 8 tool magnetic 82 and corresponding block 2 hollow slots 22 shapes in its shank is provided with, this inner magnet gonosome 82 is a same pole with the end face in opposite directions of above-mentioned magnetic pin 6;
During combination, shown in Fig. 2,3, catch 4 supports flexible member 5 and opposed concave face 11 and groove 12 places at lock 1 front end face with its shielding portion 42 convex bodys 421 covers, magnetic pin 6 is installed with in lock 1 appearance hole 13 to connect little spring 7 in the positive and negative extreme form outwardly of difference, cover sheet 3 butt joint locks 1 front end face and keep out sheet 4 and magnetic pin 6, again with the 2 noose locks 1 of blocking a shot to cover; When catch 4 moves down when hiding lock core holes 14 with shielding portion 42, make magnetic pin 6 be subjected to little spring 7 ejections and protrude out to support to end and fix at catch 4 rabbets 422.
When use key 8 undoes the lock portion's 81 opposed 2 hollow slots 22 of blocking a shot with shank when, shown in Fig. 4,5, the principle of repelling mutually with same polarity by magnetic 82 in the portion of undoing the lock 81 and magnetic pin 6, move compression little spring 7 in its repulsive force ejection magnetic pin 6 and no longer support and decide catch 4, thereby make catch 4 upwards flicked automatically by flexible member 5 pushing and pressing, open by block 2 perforation 21 insertions for key 8 to open lock core hole 14; Again, after catch 4 flicked, its press section 41 was and protrudes out, if think to cover again lock core hole 14, only need compress the press section 41 drive catch 4 that protrude out and move down, can close lock core hole 14, and make this lockset pull the structure except that having original core lock, also form a locking device of implementing in the mode of covering.
In addition, other all can use masking device of the present utility model as independent padlock, the Automotive lock that uses.
