Description

The tapered end that a kind of refrigerator or wine cabinet are used

Technical field

The present invention relates to a kind of refrigerator, wine cabinet tapered end.

Background technology

Present prior art, Chinese patent ZL 02249944.X has proposed a kind of design scheme of tapered end, and its concrete methods of realizing is not done detailed description at this.Adopt the shortcoming of this design scheme as follows: one, tapered end can be done 360 ° of rotations, but can not be spacing, if need to be spacing, need to just can achieve the goal by outside auxiliary component, and this will limit its scope of application, and owing to having increased auxiliary component, cost increases; Two, from the operating principle of this scheme, when at lock-out state, lock pearl 5 is outwards ejected and is reached in the locked groove 101, can prevent lock core 2 rotations, plays the locking purpose; In the time of need to unlocking, by key apical axis 3 is inwardly compressed, lock pearl 5 along the conical surface of cone 301 gradually free-falling finish release until drop out locked groove 101 when interior, this moment, lock core 2 can rotate freely.Here the shortcoming that exists has several: 1 〉, because the lock pearl is realized release by in-migration under the own wt freely falling body, this just means that the one side of dressing lock pearl must make progress, otherwise the lock pearl can't freely drop out in locked groove, the state that can't unlock, and this has just limited the field of employment of this lock greatly; 2〉equally for these reasons, because very light of lock pearl weight own, need to realize release by in-migration under the free falling bodies of own wt, the dimensional accuracy of the parts such as cone of this hole of just lock pearl, lock pearl being passed through, jack-up lock pearl, finish etc. all propose very high requirement, otherwise will cause locking integument because frictional force is excessive stuck and can't freely move down, and causes the tapered end operational failure.

Summary of the invention

The objective of the invention is: the tapered end that provides a kind of refrigerator or wine cabinet to use, it has simple in structure and characteristics self-locking.

The present invention is achieved in that the tapered end that a kind of refrigerator or wine cabinet are used, comprise lock body, lock core, apical axis, spring, banking pin and guide finger, described lock core is arranged in the lock body, the guide and limit groove is arranged on the external surface of described lock core, banking pin is arranged on the lock body, banking pin cooperates with the guide and limit groove, and spring is arranged in the centre bore of lock core, and apical axis and centre bore are slidingly matched; Guide finger is arranged on the apical axis; Its special character is: the annular guide table is arranged in the described lock body, have two gathering sills vertically on the annular guide table at least;

The central angle of described guide and limit groove is 180 degree;

On the external surface of described lock core the level of falling is arranged, a radially-directed hole is across the lock core that falls level left side and right side, and described guide and limit groove is arranged on the lock core that falls the level left side;

Described guide finger and radially-directed hole and gathering sill vertically are slidingly matched;

Fall the inner chamber that the lock core on grade right side and annular guide table key to the lock body passes the lock body between the hole and be rotatably assorted, the annular guide table with fall level and be rotatably assorted.

The tapered end that described a kind of refrigerator or wine cabinet are used, its special character is: described banking pin has two, two banking pin interval 90 degree.

The tapered end that described a kind of refrigerator or wine cabinet are used, its special character is: gathering sill vertically has four.

The tapered end that described a kind of refrigerator or wine cabinet are used, its special character is: described guide and limit grooved ring is around lock core.

The tapered end that a kind of refrigerator of the present invention or wine cabinet are used compared with prior art, has saved an external lock pearl, simplifies the structure; And under the effect of spring, realize self-locking.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing.

Embodiment 1

Such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the tapered end that a kind of refrigerator or wine cabinet are used, comprise lock body 1, lock core 2, apical axis 3, spring 4, banking pin 5, guide finger 6 and strike plate 7, described lock core 2 is arranged in the lock body 1, and guide and limit groove 21 is arranged on the external surface of described lock core 2, and banking pin 5 is arranged on the lock body 1, banking pin 5 has two, two banking pin 5 intervals 90 degree, banking pin 5 cooperates with guide and limit groove 21, and the central angle of guide and limit groove 21 is 180 degree; Spring 4 is arranged in the centre bore of lock core 2, and apical axis 3 is slidingly matched with centre bore; Strike plate 7 is fixed on an end of lock core 2; Guide finger 6 is arranged on the apical axis 3;

As shown in Figure 6, in the described lock body 1 annular guide table 11 is arranged, gathering sill 12 is vertically arranged on the annular guide table 11; There is key to pass hole 13 on the top board of lock body 1.

Have on the external surface of described lock core 2 and fall level 22, one radially-directed holes 23 across the lock core 2 that falls level 22 left sides and right side, described guide and limit groove 21 is arranged on the lock core 2 that falls level 22 left sides; The counterbore of centre bore one end of lock core 2 is key hole 24.

Described guide finger 6 is slidingly matched with radially-directed hole 23 and gathering sill vertically 12;

The inner chamber that lock core 2 and the annular guide table 11 of falling level 22 right sides key to the lock body 1 passes the lock body 1 between the hole 13 is rotatably assorted, annular guide table 11 with fall grades 22 and be rotatably assorted.

As shown in Figure 6, described lock body 1 has 12 4 of gathering sills vertically.

Described lock core 2 a fixedly end of strike plate 7 has circular holder, and the radial protrusion at diameter line two ends is arranged on the circular holder; The draw-in groove that has on fixing hole, the fixing hole at diameter line two ends is arranged on the described strike plate 7, and draw-in groove and radial protrusion are chimeric.One screw passes pad 8 and screws togather with lock core, thereby strike plate 7 is fixed on the lock core 2.

The present invention is when unblanking, and key inserts in the counterbore of lock core 2, and key moves forward an axle 3, Compress Spring 4, and guide finger 6 leaves axial gathering sill 12; As shown in Figure 1, make this moment lock core 2 rotate 90 degree, then strike plate 7 rotates 90 degree and unblanks, and this moment, guide finger 6 was relative with an axial gathering sill 12, if extract key, under the effect of spring 4, apical axis 3 moves, and guide finger 6 enters gathering sill 12 and self-locking;

State as shown in Figure 1, if extract key, under the effect of spring 4, apical axis 3 moves by dotted arrow direction among the figure, guide finger 6 enters gathering sill 12 and self-locking.

Adopt such structure, the axis of lock core 2 is parallel with horizontal plane, perhaps vertically with horizontal plane all can realize self-locking.

Embodiment 2
