Description

Technical Field

[0001] The utility model belongs to the technical field of door and window hinges, and in particular relates to a positionable door and window hinge. Background Art

[0002] Door and window hinges, i.e. hinges, are installed at the joints of structures such as doors, windows, cabinets, etc. that need to be opened and closed frequently, as the connecting structure between the frame and the fan. Usually, door and window hinges include two hinge parts, which are connected by a rotating shaft. Each hinge is connected to the frame and the fan respectively, so as to realize the rotation of the fan relative to the frame.

[0003] In daily use, it is usually hoped that the door body can be fixed after opening to a certain angle, and the door body can be rotated after a certain force is applied. However, the existing door and window hinges only have a simple hinge connection function. After the door body is opened, the position is not fixed, and the door body and the frame can still rotate relative to each other. When there is wind or other objects colliding, the door body will rotate relative to the frame and be closed or rotated to a certain angle. In addition, after the existing door and window hinges connect the door body and the frame, the door body cannot be closed automatically. Utility Model Content

[0054] The clamping plate 35 is arranged on the second hinge 2, and a positioning hole 36 is provided on the clamping plate 35; when the first hinge 1 and the second hinge 2 rotate relatively, the clamping plate 35 can be inserted between the first top bead 33 and the second top bead 34, and the first top bead 33 and the second top bead 34 are inserted into the positioning hole 36, so that the relative rotation of the first hinge 1 and the second hinge 2 is fixed.

[0055] The positionable door and window hinge of this embodiment, when in use, the first hinge is connected to the door body, and the second hinge is connected to the frame body. When the door body is opened, the first hinge rotates relative to the second hinge until the card plate on the second hinge is inserted between the first top bead and the second top bead, and the first top bead and the second top bead are moved to be inserted into the positioning hole, and under the action of the first elastic member and the second elastic member, the first top bead and the second top bead are pressed against each other in the positioning hole. At this point, the first hinge and the second hinge are fixed at this angle, so that the door body can be fixed and positioned when it is opened to this angle; when the door body needs to be closed, a person manually pulls the door body with force, and under the squeezing action of the card plate, the first top bead and the second top bead compress the first elastic member and the second elastic member, so that the card plate is moved out from between the first top bead and the second top bead.

[0057] Preferably, the positioning mechanism 3 further comprises:

[0058] The first guide cylinder 37 is disposed on the first hinge 1. The first elastic member 31 is disposed in the first guide cylinder 37, and the end away from the second elastic member 32 is connected to the first guide cylinder 37.

[0060] The setting of the guide cylinder can guide the first elastic member and the second elastic member, so that the expansion and contraction direction of the elastic member is along the direction of the tightening force of the two top beads, and the stability is stronger.

[0061] Preferably, the positioning mechanism 3 further comprises:

[0062] The first adjusting bolt is connected to the end of the first guide cylinder 37 away from the second guide cylinder 38, and can adjust the position along the length direction of the first guide cylinder 37; the end of the first elastic member 31 is connected to the first guide cylinder 37 through the first adjusting bolt;

[0065] Preferably, the positioning mechanism 3 further comprises:

[0066] A first mounting seat 311 is provided on the first hinge 1, and a first guide cylinder 37 is installed on the first mounting seat 311;

[0067] The second mounting seat 312 is disposed on the first hinge 1 , and the second guide tube 38 is mounted on the second mounting seat 312 .

[0068] Preferably, in the direction of inserting between the first top bead 33 and the second top bead 34, guide slopes 313 are provided on both sides of the front end of the clamping plate 35. The provision of the guide slopes can facilitate the insertion of the clamping plate between the first top bead and the second top bead.

[0069] Preferably, it also includes a shaft cylinder 4 and a rotating shaft 5; the shaft cylinder 4 includes:

[0070] A first upper shaft cylinder 41 is provided at an upper side portion of the first hinge 1;

[0071] A first lower shaft cylinder 42, provided at the lower side of the first hinge 1;

[0072] A second upper shaft cylinder 43 is provided at the upper side of the second hinge 2;

[0073] A second lower shaft cylinder 44 is provided at the lower side of the second hinge 2;

[0076] The torsion spring 6 is sleeved on the rotating shaft 5, and one end of the torsion spring 6 abuts against the first hinge 1, and the other end abuts against the second hinge 2. When the first hinge 1 and the second hinge 2 rotate relatively to open, the torsion spring 6 applies a reverse force to the first hinge 1 and the second hinge 2.

[0077] When the door is opened, the first hinge and the second hinge exert pressure on the torsion spring, and the torsion spring exerts a reverse force on the first hinge and the second hinge due to its own elastic force, so that after the door is opened, the door automatically returns to its original position after the artificial force is removed, and the door is automatically closed. In addition, the speed of automatic door closing can be adjusted by replacing torsion springs with different torque forces to meet different needs.

[0078] Preferably, it also includes:

[0079] An upper end cover 7, covering the upper end of the shaft cylinder 4;

[0080] The lower end cover 8 is covered on the lower end of the shaft cylinder 4.

[0081] After the door body is repeatedly opened and closed, the torsion spring in it is easily damaged or the elastic force is insufficient. After removing the upper end cover and the lower end cover, it is more convenient to pull the rotating shaft out of the shaft tube, remove the torsion spring, and reinstall a new torsion spring. There is no need to remove the two hinges from the door frame and the door body, which saves material costs and simplifies operations.

[0082] Preferably, a plurality of mounting holes 9 are provided on the first hinge 1 and the second hinge 2. The mounting holes are used for mounting the hinges to the door body or door frame.

[0083] Preferably, the first elastic member 31 and the second elastic member 32 are springs.

[0084] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
