Fig. 2 is the explosive view of Fig. 1 embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
In conjunction with see shown in Fig. 1, Fig. 2, a kind of safe lock strap, it comprises a belt body 1, and one end of described belt body 1 is connected on mount pad 3 by connector 2, and the other end is fastened and connected by fastener 4 and permulation lock 5; Described permulation lock 5 is that knob is to code button lockset.Concrete, described permulation lock 5 comprises button 51, knob 52, rotation set 53, housing 54, bottom plate 55, fixing buckle 56, Elastic buckle 57; Described button 51 is arranged in described rotation set 53, and the periphery of described button 51 is provided with lug boss 511, and correspondingly, the periphery of described rotation set 53 is provided with the vertical guide groove 531 that can pass for lug boss 511, and described button 51 moves along on described vertical guide groove 531; Described housing 54 is provided with the through hole 541 coordinated with described rotation set 53, button 51 shape complementarity; The upper end of described rotation set 53 is fixedly connected with described knob 52, and lower end is provided with the circumferential guide groove 532 fastened with described fixing buckle 56; Described fixing buckle 56 is fixed in the cavity of housing 54; Described bottom plate 55 coordinates with housing 54, forms a socket that can insert for described fastener 4 after coordinating; Described Elastic buckle 57 is arranged on described bottom plate 55; When described fastener 4 inserts described socket, described Elastic buckle 57 is fastened and connected with described fastener 4, and rotate knob 52 after fastening and make lug boss 511 leave the position of corresponding through hole 541, button 51 is by locking; During unblock, rotate the position that knob 52 makes the upper through hole 541 of lug boss 511 correspondence, button 51 is released, and when button 51 depresses Elastic buckle 57, described Elastic buckle 57 departs from described fastener 4.Its operating principle is as follows: when fastener 4 inserts the socket that bottom plate 55 formed with housing 54, fastener 4 fastens with the latch 571 in the middle part of Elastic buckle 57, thus it is sealed to realize safety lock band; Meanwhile, the free end of Elastic buckle 57 is just to the lower end of button 51 and by button 51 jack-up, the lug boss 511 on button 51 is made to leave housing 54, then turning knob 52, after rotation set 53, button 51 are gone to certain angle, lug boss 511 is constrained between housing 54 surface and knob 52 inner cavity top, button 51 can not be moved up and down, thus realize the locking of button 51 action; During unblock, turning knob 52, to the position of setting, makes the lug boss 511 of button 51 pass housing 54 and to depress Elastic buckle 57 and departs from fastener 4, thus realize the unblock of safe lock strap.Visible, implement the utility model, by the design of knob to code button lockset, the switch motion of conventional security lock strap can be made to become twice switch motion and can untie safe lock strap, prevent children from opening voluntarily because of curious, avoid hand clamping or article to drop and accidentally injure the generation of the accidents such as children.
More preferably, described lug boss 511 is evenly distributed with three on the periphery of described button 51, wherein, has at least the projection length of a lug boss 511 to be greater than the projection length of other lug boss 511, make permulation lock 5 have unique unlocked position, improve the disguise that this product unlocks.
More preferably, described Elastic buckle 57 is formed in one with bottom plate 55, and in an embodiment, Elastic buckle 57 is the seesaw blocks by cutting, bending tilting on bottom plate 55.Like this, without the need to adding buckle separately in housing 54 inside, simplify the internal construction of permulation lock 5, cost-saving.During installation, directly bottom plate 55 is connected on housing 54 by screw 58, easy for installation.
More preferably, described belt body 1 be provided with multiple longitudinal separation arrangement adjustment hole 11, this adjustment hole 11 for adjusting the length of belt body 1, to adapt to the installation of different spans position.Further, described connector 2 is one with the turncap 21 of screw; Belt body 1 can be fastened on described turncap 21 and mount pad 3 through described adjustment hole 11 by described screw.Like this, by the turncap 21 with screw, can conveniently one end of belt body 1 be fixed on mount pad 3, conveniently can remove again and regulate belt body 1 length, and then improve the flexibility of this product.
When needs use safety lock strap, first the position that suitable is selected, by double faced adhesive tape or glass cement, mount pad 3 is fixed on the crack between a door and its frame side of the door needing snap close, then the tape body length of prediction needed for reality, is fastened on turncap 21 and mount pad 3 through adjustment hole 11 by one end of belt body 1 by the screw on turncap 21; Then fastened by the Elastic buckle 57 of belt body 1 one end and permulation lock 5 with fastener 4, after fastening, random turning knob 52 just can lock button 51, thus permulation lock 5 and belt body 1 is fixed together; Strain belt body 1 afterwards, permulation lock 5 is arranged on the corresponding position of the opposite side of crack between a door and its frame by double faced adhesive tape or glass cement, at this moment just defines and connected by belt body 1 in crack between a door and its frame both sides, door can not be opened.When needs are opened, only need turning knob 52 to the position of setting, make the lug boss 511 of button 51 pass housing 54 and to depress Elastic buckle 57 and depart from fastener 4, safe lock strap is opened.Such unfolding mode is not a simple mode for children, but for easily simple adult.Therefore can well play and prevent children because curiosity goes to open furniture, the article of playing in furniture, avoid hand clamping or article and drop and accidentally injure the generation of the accidents such as children.
Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
