Abstract

The utility model relates to a hidden gemel which comprises a blade with a pair of rolling ears and a pin axis positioned in the rolling ear. The utility model is characterized in that the blade is a Z shape curve blade with a curve extending part in the middle; and the curve extending part of one blade is larger than the other. Therefore the utility model can solve the problem of the hidden gemel which has a complex structure, a plurality of components, is inconvenient to be made and has a high cost.

Description

Concealed hinge

Technical field:

The utility model is about the door and window part, is particularly to a kind of hinge.

Background technology:

Hinge, especially hinge-type hinge that known door leaf and doorframe link, its ear-rolling end that wears bearing pin exposes, and is inharmonious with the composite entity of door leaf of closing and doorframe, diminishes its outward appearance.No. 88202207 novel patent in Taiwan that the applicant obtains is a kind of concealed hinge that proposes at thick and heavy door-plate, when door is closed, can't see any part of hinge from appearance, improved the retaining attractive in appearance of door leaf and doorframe composite entity.But this kind concealed hinge exists complex structure, member is various, manufacturing is inconvenient, cost is high shortcoming.

Summary of the invention:

This reality is novel to be to provide a kind of concealed hinge, solves existing concealed hinge complex structure, member is various, manufacturing is inconvenient, cost is high technical problem.

The technical scheme that the utility model solves the problems of the technologies described above is as follows:

A kind of concealed hinge, comprise a pair of blade and the bearing pin that is located in the grasswort with grasswort, it is characterized in that: have approximate Z-shaped tortuous blade of being of tortuous extension in the middle of this a pair of blade is respectively, the tortuous extension of one of them blade is greater than the tortuous extension of another blade.

Above-mentioned concealed hinge is characterized in that: the fixing hole that is arranged on this a pair of tortuous blade one end is and is dislocatedly distributed.

Above-mentioned concealed hinge is characterized in that: this bearing pin upper and lower position is respectively arranged with at least one ball.

Above-mentioned concealed hinge is characterized in that: two outer faces of this a pair of blade grasswort are provided with plug sleeve.

Above-mentioned hidden hinge is characterized in that: be provided with the reinforcing chip that joins with the vanes fixed end; This reinforcing chip is provided with and the corresponding through hole of the fixing hole of blade.

Above-mentioned hidden hinge is characterized in that: can establish a concave groove in the bearing pin stage casing; Grasswort and this concave groove corresponding section are provided with the projection that is embedded in this concave groove.

The utlity model has following advantage:

1, whole hinge is hidden in a doorframe and the upward corresponding slotted eye, has increased door and doorframe overall appearance.

2, simple in structure, part is few, easily manufactured, with low cost.

3, be provided with ball, it is more apparent smooth and easy laborsaving that thick and heavy door-plate is opened and closed.

4, the bearing pin two ends both can have been kept lubricating grease not excessive by the plug sleeve capping, can prevent the dust invasion again.

5, applicable to the installation of the doorframe of different wall and door.

The specific embodiment:

Shown in Fig. 1～3, the utility model comprises a pair of

blade

1 and 2, and a bearing pin 3.The approximate Z-shaped tortuous blade that has

tortuous extension

13 and 23 in the middle of

blade

1 and 2 is respectively.This

complications extension

13 and 23 is divided into

blade

1 and 2 hinged

end

14,24 that fixed

end

11,21 with

fixing hole

12,22 and lateral margin have

grasswort

15,25 respectively.The length of tortuous extension 13 make blade 1 become linear leaf, and blade 2 becomes short blade greater than tortuous extension 23.

Fixing hole

12,22 can be suitably on fixed

end

11,21 respectively and is dislocatedly distributed.Bearing pin 3 runs through in the

grasswort

15 and 25 that is arranged at

blade

1 and 2, and a pair of

blade

1,2 is hinged to one, can make it around bearing pin 3 rotations (referring to Fig. 6).Be respectively provided to few ball 5 in the upper and lower position of bearing pin 3.Be provided with plug sleeve 4, this plug sleeve 4 from axis hole two ends that

grasswort

15,25 forms with ball 5 sealing location (for example plug sleeve 4 being welded on the outer face of following, following two grassworts 15 of blade 1), has less frictional resistance when making a pair of blade rotation, thereby the resistance of motion when having reduced door switch makes its keying more smooth and easy laborsaving.

When the utility model is installed, long blade 1 is fixed on slotted eye 81 inwalls of doorframe 8 (seeing Fig. 4 and Fig. 5), short blade 2 then is fixed on slotted eye 71 inwalls of door 7.If when slotted eye 71 inwalls of slotted eye 81 inwalls of doorframe 8 or door 7 are thin, be provided with reinforcing chip 6.This reinforcing chip 6 be provided with

blade

1,2 on

fixing hole

12,22 corresponding perforation 61.During installation, earlier this reinforcing chip 6 is set firmly (as welding) respectively on slotted

eye

71 or 81 corresponding positions (seeing Fig. 7 and Fig. 8), respectively fixed

end

11,21 contracts of

blade

1,2 are gone into then in the corresponding

slotted eye

71,81, and fit with this reinforcing chip 6, the hold-down screw of screwing on gets final product.So, the utility model just conceals in the slotted

eye

71 and 81 that places door 7 and doorframe 8.

In addition, bearing pin 3 can be provided with a concave groove 31 in its stage casing, and is provided with a projection 251 in the grasswort 25 relative positions of blade 2, and this projection 251 embeds in the above-mentioned concave groove 31 (seeing shown in Figure 6), makes blade 2 be clamped bearing pin 3 and rotates together.This projection 251 can be made with impact style after bearing pin 3 wears

grasswort

15 and 25.
