Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
The principle of work of link-type folding joint of the present utility model is identical with prior art, can with reference to prior art, so repeat no more, the utility model and the difference of prior art are that safe locking device structure is different, are described in detail below:
As Figure 1-3, link-type folding joint with automatic safe locking device of the present utility model, described link-type folding joint comprises the first connecting panel 4a and the second connecting panel 4b that are hinged, the hinged handle 3 of opposite side of the first connecting panel 4a, the hinged first connecting rod 1 of opposite side of the second connecting panel 4b, the hinged second connecting rod 2 that is connected of the other end of handle 3, first connecting rod 1 and second connecting rod 2 are threaded, handle 3 front is provided with through slot 9, button 5 to be inserted in through slot 9 and to be positioned on the front of handle 3, Compress Spring 6 is housed between button 5 afterbody and handle, button 5 can be slided along handle 3 outside face in through slot 9 on the handle 3, the touching hook 7 being arranged on handle 3 inboard is connected with button 5, second connecting rod 2 is provided with the touching lever 8 matched with touching hook 7, when link lever type folding box closes up, touching lever 8 promotes touching hook 7 and moves and Compress Spring 6, touching lever 8 enters in touching hook 7, Compress Spring 6 promotes button 5 and touching hook 7 resets, block touching lever 8, first connecting panel 4a and the second connecting panel 4b is locked.Button 5 can slide in through slot 9 on the handle 3, promotes button 7 and makes touching lever 8 depart from touching hook 7, pull handle 3 and just can open folded box.
Described touching hook 7 is L shape, and the touching lever 8 matched with touching hook 7 is cylindrical bar, and touching lever 8 is vertical with second connecting rod 2.
As shown in Figure 4, preferably, described touching hook 7 and touching lever 8 are two, and touching hook 7 is across second connecting rod 2 both sides, and two touching levers 8 are vertical with second connecting rod 2 one-tenth cross.
Above-described embodiment is only for illustration of technological thought of the present utility model and feature, its object is to enable those skilled in the art understand content of the present utility model and implement according to this, only can not limit the scope of the claims of the present utility model with the present embodiment, namely the equal change that the spirit that all the utility model disclose is done or modification, still drop in the scope of the claims of the present utility model.
