The utility model comprises a fixing seat and a movable hook seat which is hinged with the fixing seat, wherein, the fixing seat is provided with a pit, a torsional spring is fixed in the pit, one end of the torsion spring tightly presses the hook end of the movable hook seat, two pin shafts are side by side arranged in the pit of the fixing seat, one pin shaft fixes the torsion spring, and the other pin shaft fixes the movable hook seat The torsional spring is in an approximate U shape, and the hook end of the movable hook seat is provided with a positioning flange extending towards the both sdes. The blind hinge only has four components, and the utility model has the advantages of simple and reasonable structure, stress is good, firmness, durability, convenient processing, assembling and timing enhanced work efficiency and reduced cost.

Description

The blind hinge of plate fitment

The utility model relates to a kind of blind hinge that mainly is applicable to plate fitment.

The blind hinge kind of existing plate fitment is more, structure is different.Its most of structures are comparatively complicated, and part is more, processing, assembling, adjusting inconvenience.

The purpose of this utility model aim to provide a kind of simple in structure, mounting or dismounting are convenient, the blind hinge of the plate fitment of firm and durable, to overcome the deficiencies in the prior art part.

By the blind hinge of the plate fitment of this purpose design, comprise that holder and the activity hinged with it collude seat, its architectural feature is that described holder is provided with a pit, fixes a torsion spring in the hole, an end of torsion spring presses the end that colludes that seat is colluded in activity.

Two bearing pins have been arranged side by side in the pit of described holder; Bearing pin is torsion spring fixedly, and another root bearing pin fixedly activity colludes seat.Two bearing pins are connected to U-shaped.Described torsion spring is approximate U-shaped.The end that colludes that seat is colluded in described activity is provided with the locating flange that extends to both sides, and the openend of U-shaped torsion spring presses described locating flange.

The part of this blind hinge only has four, and it is simple and reasonable, and is stressed better, firm and durable, and process and assemble and adjustment are all more convenient, can improve work efficiency, reduce cost.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 9-Figure 14 for holder with movable when colluding relative motion U-shaped torsion spring and locating flange the force-bearing situation schematic diagram.

Referring to Fig. 1-Fig. 6, holder 5 central authorities are provided with a pit 4, two bearing pin 3, two bearing pins are set in the hole are connected to U-shaped, insert the pin shaft hole from the outside.Bearing pin by the limit, hole is the movable swivel pin that colludes seat 1, and the end that colludes that seat 1 is colluded in activity is provided with the locating flange 6 that extends to both sides, and the trough rim 7 that turns in the other end is provided with is so that the plank location.Fix an approximate U-shaped torsion spring 2 on the middle bearing pin, an end of torsion spring presses the locating flange 6 that seat is colluded in activity.When holder and activity were colluded seat and relatively rotated, the openend of U-shaped torsion spring 2 pressed the locating flange 6 that seat 1 is colluded in activity all the time, as Fig. 9-shown in Figure 14.

Fig. 7, Figure 8 shows that holder 5 and movable connection status of colluding seat 1 and plank 8.

Holder and activity are colluded seat and are metallic stamping pieces.
