Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Fig. 1 to 17, this concealed installation door chain, comprise Button Block 1, slot 2, fixed muffle 3, described slot 2 comprises chain 201 and cuff link 202, described cuff link 202 is fixed on the left end of chain 201, the left end of described fixed muffle 3 is sealed by right baffle-plate 4, right-hand member is sealed by right baffle plate 5, inner barrel 6 is provided with in described fixed muffle 3, the left end of described inner barrel 6 is sealed by fixed head 7 and fixed head 7 and inner barrel 6 are fixed together, the inside of described inner barrel 6 is provided with rebound spring 8, one end of described rebound spring 8 is fixed on right baffle plate 5, the cross section of described chain 201 is rectangle, described right baffle-plate 4 is provided with circular open 9, described fixed head 7 is provided with rectangular through-hole 10, the size of described rectangular through-hole 10 and the cross section of chain 201 match, the right-hand member of described chain 201 is successively through circular open 9, rectangular through-hole 10 is fixed together with the left end of rebound spring 8, the external surface of described inner barrel 6 is provided with the drive unit 11 for driving inner barrel 6 to rotate, described cuff link 202 is strip, the length direction of described cuff link 202 and the length direction of chain 201 orthogonal, the Central Symmetry mask of the position distance cuff link 202 that cuff link 202 is connected with chain 201 has certain distance, the length direction of described Central Symmetry face and cuff link 202 is orthogonal, described Button Block 1 comprises pedestal 101, cavity 102 is provided with in described pedestal 101, described pedestal 101 has the first mounting plane 103 and the second mounting plane 104, described first mounting plane 103 and the second mounting plane 104 orthogonal, described first mounting plane 103 is provided with groove 105, bearing of trend and second mounting plane 104 of described groove 105 are orthogonal, one end of described groove 105 extends to the second mounting plane 104, the other end of described groove 105 extends to cavity 102 and is communicated with cavity 102, the cross section size of described groove 105 and the cross section size of cuff link 202 suitable, described cuff link 202 can to stretch in cavity 102 along groove 105 and cuff link 202 can rotate for axis with chain 201 in cavity 102.The operating principle of this concealed installation door chain is as follows: in pass in front of the door, first inner barrel 6 is driven to rotate by drive unit 11, because the left end of inner barrel 6 to be sealed by fixed head 7 and fixed head 7 and inner barrel 6 are fixed together, thus inner barrel 6 rotation can drive fixed head 7 to rotate, the size of rectangular through-hole 10 simultaneously fixed head 7 arranged and the cross section of chain 201 match, thus chain 201 can be driven when fixed head 7 rotates to rotate simultaneously, chain 201 rotation can drive cuff link 202 to rotate, when cuff link 202 turns to the groove 105 of its cross section aligning Button Block 1, shut the door, cuff link 202 stretches in cavity 102 along groove 105, then by drive unit 11, cuff link 202 is rotated again, because cuff link 202 is strip, and the cross section size of the cross section size of groove 105 and cuff link 202 is suitable, thus, after cuff link 202 is rotated to an angle, cuff link 202 can be stuck in cavity 102, now door chain is in antitheft opening, if now will open the door, chain 201 can be drawn out, due to chain 201 length angle, thus door can only be opened 5 ~ 8 cm, after shutting the door, chain 201 is taken in fixed muffle 3 under the effect of rebound spring 8, if remove anti-theft state, when only cuff link 202 need be made to turn to the groove 105 of its cross section aligning Button Block 1 by drive unit 11, just door can be opened completely, the unlatching of this concealed installation door chain is realized by drive unit 11 with releasing, and drive unit 11 makes to be arranged on inner barrel 6, inner barrel 6 is positioned at door-plate, thus drive unit 11 just can be arranged on the inner side of door-plate, and Button Block 1 does not arrange floatless switch, just the inner side and outer side of door pocket can be arranged on arbitrarily, that inward opening door or outward opening door drive unit 11 are all positioned at an inner side like this, ensure that safety, go for inward opening door and outward opening door, Button Block 1 does not arrange anti-theft switch simultaneously, make the structure of Button Block 1 simpler, only a cavity 102 need be set, groove 105, greatly can reduce the volume of Button Block 1, door sleeve moulding can not be destroyed, the surface area that Button Block 1 exposes also can correspondingly reduce, whole door can be made more attractive in appearance.
In the above-described embodiment, at closing time, can adaptively stretch in cavity 102 along groove 105 in order to cuff link 202 can be made, the intersection of described groove 105 and the second mounting plane 104 passes through arc transition, owing to adopting arc transition, even if the cross section of cuff link 202 does not have alignment indentation 105, under the External Force Acting of closing the door, cuff link 202 also can slip in groove 105 along arc surface is adaptive, without the need to manually adjusting the position of cuff link 202, just can shut the door easily, faster and more convenient operation.
Described drive unit 11 can have various ways to realize, as long as inner barrel 6 can be driven to rotate, because inner barrel 6 is positioned at door-plate inside, in order to control to rotate easily from outside, the utility model provides a kind of convenient preferred embodiment controlled: described drive unit 11 comprises the first angular wheel 1101 being arranged on inner barrel 6 external surface, the surface of described fixed muffle 3 has breach 1102, described first angular wheel 1101 is positioned at breach 1102, the described central axis of the first angular wheel 1101 and the central axes of inner barrel 6, described fixed muffle 3 is provided with axis of rotation 1103, described axis of rotation 1103 is provided with the second angular wheel 1104, the central axis of described axis of rotation 1103 and the central axis of the first angular wheel 1101 orthogonal and the second angular wheel 1104 and the first angular wheel 1101 engage each other.Axis of rotation 1103 only need expose out by this drive unit 11, and miscellaneous part can be hidden in door-plate, to increase the aesthetic property of door.By rotating axis of rotation 1103, axis of rotation 1103 rotation can drive the second angular wheel 1104 to rotate, second angular wheel 1104 and then drive the first angular wheel 1101 rotate, because the first angular wheel 1101 is fixed on inner barrel 6 external surface, thus the first angular wheel 1101 rotation can drive inner barrel 6 to rotate.
Because cuff link 202 is strip, thus when cuff link 202 stretches into after in cavity 102, only need rotate 90 degree just can make cuff link 202 be stuck completely, for the ease of adjusting the anglec of rotation of cuff link 202, described first angular wheel 1101 is 1/4th angular wheels, like this when rotating axis of rotation 1103, also 90 degree can only be rotated, so just, can once adjust to the right place, without the need to repeating adjustment, handled easily.
In addition, for the ease of rotating axis of rotation 1103, the end of described axis of rotation 1103 is provided with the anti-theft switch 1105 for driving axis of rotation 1103 to rotate, because anti-theft switch 1105 is when applying External Force Acting, only have two ultimate limit states, it effectively can be avoided when rotating axis of rotation 1103 to rotate excessively, damage is caused to concealed installation door chain.
