As shown in Figure 4 A and 4 B shown in FIG., in the preferred embodiment of the present invention, receiving hole 43 penetrates the first side of spoon body 4 41 and second side 42, in addition to the inner integument 10 of overcoat pearl 9 and first, key hoodle 6 also has the second inner integument 12, the first spring 11 The other end supports the second inner integument 12.What the first spring 11 the first inner integument 10 of offer and the second inner integument 12 moved to two opposite directions Power, key overcoat pearl 9 are used for the moving range for limiting the first inner integument 10 and the second inner integument 12, it is not departed from key spoon body 4. First inner integument 10 and the second inner integument 12 protrude from first side 41 and second side 42 respectively in the presence of the first spring 11, and The first inner integument 10 and the second inner integument 12 can be bounced back in receiving hole 43 in the presence of external force.
Refer to Fig. 4 B and Fig. 4 C, overcoat pearl 9 can be the cylindrical shape of open at both ends, and the upper end of overcoat pearl 9 formed with For the first annular boss 91 of spacing first inner integument 10, the inwall of receiving hole 43 is formed with for spacing second inner integument 12 Second ring boss 44.First inner integument 10 and the second inner integument 12 are spherical crown shape, and base is respectively equipped with the He of stop part 101 of annular 121, the bottom surface of the second inner integument 12 is provided with the depression 122 that is engaged with the first spring 11, the bottom surface structure of the first inner integument 10 phase therewith Together, two of the first spring 11 is supported in the depression of the first inner integument 10 and the second inner integument 12 respectively.
When key 1 is inserted in the key slot 31 of rotating cylinder 14, the first inner integument 10 and the second inner integument 12 are simultaneously by key The centre that is pressed against of the inwall of groove 31 is drawn close, while compresses the first spring 11.When the first inner integument 10 and the second inner integument 12 all bounce back When in receiving hole 43, key 1 is with regard to that can insert in key slot 31.
Fig. 5 A and Fig. 5 B show the corresponding lock core 2 of key 1 with the present invention, and it includes cylindrical rotating cylinder 14 and therewith The shell 13 being engaged, it also has pin tumbler of lock cylinder 15.As shown in Fig. 6 Fig. 7, pin tumbler of lock cylinder 15 includes:Mobile beads 16, fixed pearl 17th, second spring 18 and block 19, the second receiving hole 24, fixed pearl 17, second spring 18 and block are wherein provided with shell 13 19 are contained in the second receiving hole 24, and block 19 and the inwall of the second receiving hole 24 are fixed, one end of second spring 18 and block 19 are supported, and the other end is supported with fixed pearl 17, formed with the 3rd for spacing fixed pearl 17 on the inwall of the second receiving hole 24 Annular boss 25;The key slot 31 for being used for inserting key 1 is provided with rotating cylinder 14, is offered on rotating cylinder 14 for making the He of key slot 31 The mobile beads through hole of second receiving hole 24 insertion(Do not indicated in figure), mobile beads 16 are movably contained in mobile beads through hole, One end of mobile beads 16 is located in key slot 31, and the other end and the bottom connection of fixed pearl 17 touch;Fixed pearl 17 is in second spring The inner surface of shell 13 is protruded from the presence of 18, and it is fixed in the presence of mobile beads 16 when key 1 acts on mobile beads 16 Pearl 17 can be bounced back in the second receiving hole 24.
As shown in fig. 7, lock core 2 also includes lower pearl 20, upper pearl 21, the 3rd spring 22 and fixed cover pearl 23;Opened in shell 13 Provided with the upper hole of bead for accommodating upper pearl 21, the 3rd spring 22 and fixed cover pearl 23(Do not indicated in figure), the two of the 3rd spring 22 Pearl 21 and fixed cover pearl 23 are supported respectively in end;Insertion key slot 31 and the upper hole of bead are offered in rotating cylinder 14 is used for accommodating lower pearl The 20 lower hole of bead(Do not indicated in figure);Upper pearl 21 protrudes from the hole of bead in the presence of the 3rd spring 22 makes its upper end be located at lower pearl In hole, the first side 41 and second side 42 of inserting the key 1 of key slot 31 are respectively acting on mobile beads 16 and lower pearl 20, When key 1 acts on lower pearl 20, in the presence of the lower pearl 20 on pearl 21 bounce back on described in the hole of bead.
Please continue to refer to Fig. 7, when being not inserted into key 1, fixed pearl 17 stretches into rotating cylinder 14 in the presence of second spring 18 Screens is internally formed, prevents the rotation of rotating cylinder 14.Meanwhile upper pearl 21 is also stretched under rotating cylinder 14 in the presence of the 3rd spring 22 The hole of bead is internally formed screens, the same rotation for preventing rotating cylinder 14.
Fig. 8 is refer to, after key 1 is inserted, key hoodle 6 enters in the key slot 31 of rotating cylinder 14, when the correct position of arrival When putting, the first inner integument 10 and the second inner integument 12 move round about in the presence of the first spring 11, protrude from spoon body 4 respectively First side 41 and second side 42, wherein the first inner integument 10 promote mobile beads 16 to the direction of shell 13 move, mobile beads 16 Promote fixed pearl 17 to leave inside rotating cylinder 14 again, while compress second spring 18.Equally, the second inner integument 12 promotes lower pearl 20 outside The direction of shell 13 is moved, and lower pearl 20 promotes upper pearl 21 to leave the lower hole of bead in rotating cylinder 14, and fixed cover pearl 23 is fixed, the 3rd bullet Spring 22 is compressed.
When whole motion reaches equilbrium position and when stopping, mobile beads 16 and the contact surface of fixed pearl 17, lower pearl 20 with it is upper The contact surface of pearl 21 is tangent with the internal circular surfaces of shell 13, at this moment rotates key 1, rotating cylinder 14 is with regard to energy concomitant rotation, so as to open Open lock core 2.
When insertion without key hoodle 6 key 1 when, can not pushing lock cylinder 2 mobile beads 16 and lower pearl 20 be displaced outwardly, Rotating cylinder 14 is unable to opening lock master 2 at all because screens can not rotate.
The key and corresponding lock core of the present invention can be widely applied in various spring locks, greatly improve the safety of lockset Property.
Certainly, described above is the preferred embodiment of the present invention, it is noted that for the ordinary skill of the art For personnel, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications It is considered as protection scope of the present invention.
