Description

Hinge connection structure

The invention relates to a connecting structure, in particular to a connecting structure of a hinge which can bear a large weight and can be applied to a large-sized axially folding folding structure device.

In life, small things that are often inconspicuous will play a major role. The hinge also plays such an inconspicuous but important role. It is used very frequently in daily life. Through the opening and closing of the hinge, the folding is driven. The folding and closing of structural devices are mainly applied to the opening and closing of various doors and windows, whether it is general doors, windows, cabinets, boxes, etc., as long as the objects that need to be folded through the pivot method will mostly need to use hinges To connect.

Please refer to FIG. 1, which is a conventional hinge connection method. Taking the connection between a plurality of door panels 11 in the folded door frame 10 as an example, the most commonly used hinge is also called the world lock 20, and the world lock 20 is also all doors. The most commonly used hinge style in structures that need to be axially folded, such as windows and implements, is mainly composed of a left turn piece 21 and a right turn piece 22, which are connected by the left turn piece 21 and the right turn piece 22. The door panel 11 enables the door panel 11 to be folded through the left turn member 21 and the right turn member 22.

However, the conventional hinge connection method is still applicable to ordinary doors and windows. If it is to be applied to a larger type or heavier, it needs high load-bearing. On objects, it is easy to cause the hinge to have a short life and easy to be damaged due to insufficient load-bearing capacity, and more force must be applied in order to fold, which causes inconvenience in use.

Secondly, the main object of the present invention is to provide a hinge connection structure which has better load-bearing capacity and uses more labor-saving hinges.

In order to achieve the above object, the present invention discloses a hinge connection structure, which is used on a folding structure device that can be folded axially, which includes: a hinge provided with a left turn piece, a right turn piece, and the left turn piece It is pivotally connected with the right turning part through a pivot rod; a unidirectional chain, one end of the unidirectional chain is fixed on the hinge, and the other end is connected with the folding structure device; an elastic part, the elastic part is sleeved on the The unidirectional chain is outside, and the elastic member can expand and contract axially.

Wherein, the folding structure device has a first folding part connected with the left turning part and a second folding part connected with the right turning part.

Wherein, the one-way chain is fixed on the folding structure device through a connecting rod.

Among them, the folding structure device is one of doors and windows.

In this way, according to the present invention, the unidirectional chain can only be bent in one direction, which provides better thrust for the hinge when closed, plus the restoring force after the elastic member contracts, and is used in the heavier folding structure device On the top, the hinge can bear a large weight.

The detailed content and technical description of the present invention are now further described by embodiments, but it should be understood that these embodiments are for illustrative purposes only, and should not be construed as limitations on the implementation of the present invention.

Please refer to Figure 2. The invention discloses a hinge connection structure, which includes: a hinge 100 provided with a left turn member 110 and a right turn member 120, the left turn member 110 and the right turn member 120 are pivotally connected by a pivot lever 130, A one-way chain 200, one end of the one-way chain 200 is fixed on the hinge 100 through a fixing member 140, and an elastic member 300, the elastic member 300 is sleeved outside the chain 200, and the elastic member can be axially retractable .

Among them, the unidirectional chain 200 (also known as anti-bending chain) has directionality, and the difference from the general chain is that it can withstand the thrust in addition to the tensile force, so the unidirectional chain 200 can withstand the thrust when pushing the unidirectional chain 200 And keep it in a straight line without twisting. However, due to the directionality, the bending angle of the unidirectional chain 200 is limited to between 100 degrees and 180 degrees. If the unidirectional chain 200 is bent to a state of less than 100 degrees in use, then the unidirectional chain 200 Chain 200 exerts thrust to push it back to 180 During the process, there will be a jamming phenomenon between the chain meshes at the bend of the one-way chain 200, making it impossible to continue to push. Therefore, the restoring force of the elastic member 300 is needed to help the one-way chain break through the jamming phenomenon .

Please refer to Figure 3 and Figure 4 again. The connecting structure of the hinge of the present invention is mainly used on a folding structure device 400 which can be folded axially. The folding structure device 400 is one of doors and windows. The best embodiment of the folding structure device 400 is described, and the connecting structure of at least one group of hinges is connected to the folding door, and the connecting structure of the group of hinges can also be provided above and below the folding door. The folding structure device 400 has a first folding part 410 (the folding door panel is shown as an example) and a second folding part 420 (the folding door panel is shown as an example).

In practice, the left turning part 110 of the hinge 100 is connected to the first folding part 410 of the folding structure device 400, and the right turning part 120 of the hinge 100 is connected to the second folding part 420, the One end of the one-way chain 200 is fixed to the left turn member 110 of the hinge 100 through a fixing member 140, and the other end is connected to the second folding part 420 of the folding structure device 400, which is shown in the embodiment The upper and lower sides of the folding door are respectively provided with a group of hinge connecting structures, and the upper frames 411, 421 and the lower frame of the second folding door panel serving as the first folding part 410 and the second folding part 420 are respectively connected through the two sets of hinges 100 412 and 422, and hide the one-way chain 200 and the elastic member 300 into the upper frame 411 and the lower frame 421 of the second folding part 420, respectively. Furthermore, in order to save costs, the length of the unidirectional chain 200 can be shortened, and connected to the unidirectional chain 200 and the second folding part 420 through a connecting rod 210.

Please refer to Figure 5 again. Through the above structure, when the door is tightly closed, The one-way chain 200 on the hinge 100 is straight, and the elastic member 300 on the periphery is in a relaxed state. When the door is to be opened, the first folding part 410 is pushed and the second folding part 420 is folded to form an open door status. At this time, the left turning member 110 fixing one end of the one-way chain 200 pulls the one-way chain 200 to rotate to the left as the first folding part 410 moves, so that the connecting rod fixing the other end of the one-way chain 200 210 The elastic member 300 is compressed as the unidirectional chain 200 moves. When the first folding portion 410 and the second folding portion 420 are folded, the unidirectional chain 200 on the first hinge 100 is in a curved state The elastic member 300 on the periphery is in a compressed state.

Please refer to Figure 6 and Figure 7 again. When the opened door is to be closed, the first folding part 410 is pulled apart and the second folding part 420 is driven, and the outer frame of the folding door as the folding structure device 400 is locked together to form a closed state. The one-way chain 200 has directionality, so the one-way chain 200 can withstand the thrust and keep in a straight state without twisting when being pushed. This feature enables the hinge 100 to provide a more stable and smooth door frame closing action. When the first folding part 410 is pulled back, the left turning member 110 is pushed to push the one-way chain 200, so that the one-way chain 200 rotates to the right with the left turning member 110, and is compressed by the elastic member 300 The restoring force of the state returning to the relaxed state helps the connecting rod 210 break the jammed state of the curved unidirectional chain 200, so that the unidirectional chain 200 can smoothly receive the thrust and return to a linear state. The left turn piece 110 and the The right turn 120 can be closed tightly.

Therefore, the above embodiment shows that the advantage of the present invention is that through the combination of the one-way chain 200 and the elastic member 300 and the hinge 100, a greater load-bearing capacity can be achieved, and it can be applied to a larger size that needs to be folded through the hinge 100 Objects.

However, the above are only the preferred embodiments of the present invention. The scope of implementation of the present invention cannot be limited in this way, that is, any simple equivalent changes and modifications made according to the patent application scope and description of the present invention are still covered by the scope of the present invention patent.
