Abstract

The utility model relates to a lock head, particularly a T-shaped key lock head which is composed of a lock shell, a lock core, a lock pin, a lock beam, etc. The utility model is characterized in that the key with a T-shaped cross-section is arranged in the lock head; the upper surface of the T-shaped cross-section of the key is provided with grooves, and both faces of the vertical part of the T-shaped cross-section of the key is provided with a geometric shape which is used for matching with difference shapes of lock cores; the outer surface of the lock shell is a label surface; the surface of the T-shaped key is provided with a label surface the same with the outer surface of the lock shell. The utility model has the advantages of reasonable design, simple structure and low cost. Because the T-shaped key lock head has the characteristics of surface label and matched lock shell and key, the T-shaped key lock head is very suitable for storage boxes in a bank, a hotel and a recreation ground, and is matched with a bicycle and a motorcycle which are managed.

Description

The T shaped key tapered end

The utility model relates to tapered end, particularly a kind of T shaped key tapered end.

At present, the mechanical lockset of Sheng Chaning on the market, the cross section of its key is mainly in-line, cross, circle etc., and this kind key is unfavorable for management, and does not also come out in the city for ease of the T shaped key of management.

The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art part, provides a kind of reasonable in design, simple in structure, and cost is low, is beneficial to the T shaped key tapered end that uses and manage.

The purpose of this utility model is to realize like this; A kind of T shaped key tapered end, be made of lock housing 1, lock core 4, lock pin 6 and lock bridge 8 etc., it is characterized in that being provided with in the tapered end cross section is T shaped key 5, is provided with groove 14 above the horizontal shape of described T shaped key 5, its two sides, vertical part is provided with geometry, and geometry is used and joined difform lock core 4; The two sides of the T shape vertical part of T shaped key also is provided with the pearl hole 15 of different depth; The following tongue and groove 16 that also is provided with of vertical part; Lock housing 1 external surface is an index face 17; T shaped key 5 surfaces are provided with the index face 18 identical with lock housing 1 external surface; Also be provided with the geometry suitable geometry set in the lock core 4 with T shaped key 5.

The drawing of accompanying drawing is described as follows:

Fig. 1 is a structural representation of the present utility model,

Fig. 2 is a structural representation of the present utility model,

Fig. 3 is the utility model Key structure schematic diagram,

Fig. 4 is a key geometry schematic diagram.

Below in conjunction with drawings and Examples, the utility model is described in further detail: lock housing 1, alignment pin 2, spring 3,7,9,12, lock core 4, T shaped key 5, lock pin 6, lock bridge 8, flat pearl 10, the decorative pearl on top of an official cap 11, diaphragm seal 13, groove 14, pearl hole 15, tongue and groove 16, index face 17,18.

Shown in Fig. 1～2, a kind of T shaped key tapered end, constitute by lock housing 1, lock core 4, lock pin 6 and lock bridge 8 etc., it is characterized in that being provided with in the tapered end cross section is T shaped key 5, be provided with groove 14 above the horizontal shape of described T shaped key 5, its two sides, vertical part is provided with geometry, and geometry is used and joined difform lock core 4; The two sides of the T shape vertical part of T shaped key also is provided with the pearl hole 15 of different depth; The following tongue and groove 16 that also is provided with of vertical part.Lock core 4 is slidingly matched in lock housing 1, and by the reciprocal position of alignment pin 2 controls, lock pin 6 pumps in lock core 4 and lock bridge 8, turn left when sealed when lock bridge 8, lock pin 6 falls into lock bridge 8 breach, is subjected to the active force of spring 3, key 5 is withstood in lock core 4 slip of turning right, and finishes sealed.When inserting key 5 and promote lock cores 4 and be moved to the left in the lock core 4 breach to last lock pin 6, lock bridge 8 is moved right by the active force of spring 7, promotes lock pin 6 and moves up and finish breakdown action.Seal 13 is slidingly matched in the lock housing groove.When inserting key 5, key 5 contacts with the inclined-plane of diaphragm seal 13, and on diaphragm seal 13 tops, after taking out key 5, diaphragm seal 13 is subjected to the active force of spring 12 and glides, and finishes sealing.

Pearl in the tapered end can be adorned single pearl and become the primary and secondary pearl, and the bead loading orientation can the unit's of allowing bead loading, dibit bead loading or three bead loadings.

Shown in Fig. 3～4, lock housing 1 external surface is an index face 17; T shaped key 5 surfaces are provided with the index face 18 identical with lock housing 1 external surface; Also be provided with the geometry suitable geometry set in the lock core 4 with T shaped key 5.On index face, impression or edge paste various marks or number, the multiple reflectorised paint in surface (can clearly see mark clearly when being convenient to be subjected to night illumination to penetrate).After insertion was key operated, the mark number digital and on the key of the mark on the lock housing matched; When take out key close close lock after, the mark number is imperfect.If other key promptly enables lock is opened after inserting lock, the mark number is also misfitted.

The utility model has reasonable in design compared to existing technology, and is simple in structure, and cost is low, by Have surperficial mark, lock housing, the supporting characteristics of key in the T shaped key tapered end, be well suited for silver Depositing in thing case and bicycle, the motorcycle in row, hotel, the public place of entertainment supports the use and manages.
