The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for explanation the present invention, but are not used for limiting the scope of the invention.
Fig. 1 shows the decomposing schematic representation of present embodiment rotating latch, and Fig. 2 is the structural representation of rotary locking cylinder among Fig. 1, and with reference to diagram, this rotating latch comprises: locking sleeve 1, and it is the column cylinder of an end opening; Card column 4 is arranged on the inwall of described locking sleeve 1; Rotary locking cylinder 5 comprises with described locking sleeve 1 shape being complementary and coaxial sticking department 52 that offer the recessed road of bent of an end opening on described sticking department 52 outer walls, described card column 4 is passed the recessed road of described bent and is locked in its end.Wherein, when the rotating latch of present embodiment is used for connecting two connectors, two decorations as shown in Figure 3, locking sleeve 1 is used for being installed in wherein the first decoration 6, rotary locking cylinder 5 is installed on the second decoration 7, sticking department 52 inserts in the described locking sleeve 1, card column 4 is corresponding with the opening in the recessed road of bent, by rotation with move up and down described rotary locking cylinder 5, namely can realize card column 4 to pass the recessed road of bent and reach its end, realize the locking between locking sleeve 1 and the rotary locking cylinder 5, when needs were taken locking sleeve 1 and rotary locking cylinder 5 apart, the opposite direction when installing was rotated and gets final product.This rotating latch overall structure is simple, and easy accessibility can not come off easily, and safety coefficient is high.
Further, fixing when locking between rotary locking cylinder 5 and the locking sleeve 1 in order to strengthen, be provided with spring 2 in described locking sleeve 1, the inner end of spring 2 is positioned at described locking sleeve 1, the outer end of spring 2 by described card column 4 blocks in described locking sleeve 1.Rotary locking cylinder 5 relies on the elastic force effect of spring 2 after locking with card column 4, rotary locking cylinder 5 can be held out against, and makes between rotary locking cylinder 5 and the card column 4 and can not arbitrarily relatively move, and the structure of locking is more firm.
Be provided with the pressure block piece between the outer end of described spring 2 and the described card column 4, described pressure block piece presses gear on described spring 2 by described rotary locking cylinder 5, by described pressure block piece, in the time of can avoiding rotary locking cylinder 5 holddown spring 2 between the two discontinuity and that spring stress distortion is produced is unusual.Described pressure block piece can be the steel disc 8 shown in the steel ball 3 shown in Fig. 1 or Fig. 4, when pressing block piece to be steel ball 3, not only can reduce the use length of spring 2, reduce the length of whole locking sleeve 1, dwindle the overall dimensions of rotating latch, the operation in the time of can also making things convenient for rotating latch to install.
In the present embodiment, described card column 4 is two, these two card columns, 4 coaxial settings; The position in the recessed road of bent of offering on described sticking department 52 outer walls and quantity are corresponding one by one with position and the quantity of described card column 4, can guarantee the stability of recessed road and card column 4 lockings.As shown in Figure 2, the recessed road of described bent comprises the first recessed road 56 with described sticking department 52 axially parallels, with 56 connected vertically second recessed roads 57, the described first recessed road, with 57 the connected vertically the 3rd recessed roads 58, the described second recessed road, one end opening in the described first recessed road 56, the described the 3rd recessed road 58 and the first recessed road 56 are positioned at the same side in the described second recessed road 57.The recessed road setting of this kind bent, when rotary locking cylinder 5 is installed with locking sleeve 1, opening with the first recessed road 56 is corresponding with the position of card column 4 first, the elastic force that overcomes spring 2 firmly presses down rotary locking cylinder 5, make card column 4 pass the described first recessed road 56, then described rotary locking cylinder 56 is rotated, make card column 4 pass the second recessed road 57, make at last card column 4 enter the 3rd recessed road 58, do not need the people for applying active force this moment, only rely on the elastic force effect of spring 2, just can make card column 4 pass the 3rd recessed road 58 and be locked in the end in the 3rd recessed road 58, the time simple in structure, locking is installed also very convenient, and it is firm to lock, and carries out opposite operation during dismounting and gets final product.
When locking sleeve 1 being installed on the first decoration 6, only need to perforate on the first decoration 6, locking sleeve 1 is fixed in the hole gets final product.When rotary locking cylinder 5 being installed on the second decoration 7, present embodiment is provided with the fixed part 51 that is connected with its one at the other end of described sticking department 52, the fixed installation that fixed part 51 is used between rotary locking cylinder 5 and the second decoration 7, described fixed part 51 and described sticking department 52 coaxial settings, axially offer jack hole 53 perpendicular to it on the described fixed part 51, jack hole 53 is used for being connected with the second decoration 7.And, also be provided with the groove that is connected respectively with described jack hole 53 both ends opens on described fixed part 51 outer walls, axial and the length of described groove is corresponding consistent with the axial and length of described fixed part 51, be convenient to when the rotating latch with present embodiment is used for the connection of necklace or bangle, the cotton rope of wearing chain can be fixed in the jack hole 53, then make cotton rope pass through groove, can not cause the part protrusion of cotton rope on fixed part 51 outer walls, affect attractive in appearance.
Also be provided with projection 55 on the outer wall of fixed part 51, when rotary locking cylinder 5 being installed on the second decoration 7, the projection 55 firm intensity that can strengthen between the two are difficult for making rotary locking cylinder 5 to come off from the second decoration 7.The diameter of described sticking department 52 and fixed part 51 junctions is greater than the opening diameter of described locking sleeve 1, to carry out spacing to the locking between rotary locking cylinder 5 and the locking sleeve 1.
The rotating latch of present embodiment, the first-selected snap close that can be used for pearl, jade, agate and the passementerie necklace such as quartzy or bangle, whole snap close can be built in the inside such as pearl, jade, agate and crystal, makes whole piece necklace or bangle jewellery outward appearance more complete, more attractive in appearance.When being produced on this snap close on the above-mentioned ornaments, a plurality of ornaments can be arranged in pairs or groups arbitrarily connects combination, realizes the variation of ornaments pattern.
As can be seen from the above embodiments, rotary locking cylinder of the present invention is by its upper recessed road of bent that arranges, can kayser on card column, the locking of realization locking sleeve and rotary locking cylinder, it is simple in structure, easy to use; The design in the recessed road of bent, can avoid arbitrarily coming off between rotary locking cylinder and the locking sleeve, only have artificial bending rule according to the recessed road of bent to be rotated, locking sleeve can be separated dismounting with rotary locking cylinder, snap close is firm, difficult threads off, and safety coefficient is high.
The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the technology of the present invention principle; can also make some improvement and replacement, these improvement and replacement also should be considered as protection scope of the present invention.
