Description

Technical Field

[0001] This utility model relates to the field of folding door technology, and in particular to an upward folding door. Background Technology

[0002] Folding doors are mainly suitable for partitioning or screening in workshops, shopping malls, office buildings, showrooms, and home decoration. They can be installed as interior or exterior doors.

[0003] Currently, traditional folding doors have some shortcomings in use. For example, common side-folding doors require a large space on the side for storage after folding, which can be a waste of space in places with limited space. While bottom-folding doors save side space to some extent, the bottom folding structure is prone to accumulating dust and debris during use, and may affect the flatness of the floor, making them difficult to clean and use daily.

[0004] Therefore, it is necessary to propose an upward folding door to address the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an upward folding door to solve the above problems.

[0006] A folding door includes a folding door body, a door track, and a lifting drive mechanism. The two sides of the folding door body are connected to the door track. The folding door body includes a first door leaf, a second door leaf, and a third door leaf. The upper part of the first door leaf is connected to the door track via a first hinge shaft. The lower part of the first door leaf is hinged to the second door leaf via a second hinge shaft. The second door leaf is hinged to the door track via a third hinge shaft. The lifting drive mechanism is located within one of the door tracks, and the output end of the lifting drive mechanism is connected to one end of the third hinge shaft.

[0007] Preferably, both ends of the second hinge shaft are connected to first pulleys.

[0008] Preferably, the two ends of the third hinge shaft are connected to second pulleys.

[0009] Preferably, the other end of the third hinge shaft is connected to a shock-absorbing block, which is made of rubber or silicone material.

[0010] Preferably, an auxiliary shock absorber is provided in another door track.

[0011] Preferably, the auxiliary shock absorber includes a shock absorber cylinder, a shock absorber rod, and a sliding plug. The shock absorber rod is connected to the shock absorber cylinder through the sliding plug. A first shock absorber spring is provided between the sliding plug and the shock absorber cylinder. A second shock absorber spring is fitted onto the shock absorber rod.

[0012] Preferably, the third hinge shaft is connected to a push-pull rod.

[0013] Preferably, a sound-insulating and vibration-damping pad is provided inside the door track, and the sound-insulating and vibration-damping pad is made of EPDM rubber.

[0014] Compared with the prior art, the present invention has the following advantages: The present invention is provided with a folding door body, a door track and a lifting drive mechanism. The lifting drive mechanism can drive the folding door body to rise and fall along the door track. The auxiliary shock-absorbing frame plays an auxiliary shock-absorbing role. The door track is provided with sound insulation pads and shock-absorbing pads, which can play a role in shock absorption, sound insulation and noise reduction. Attached Figure Description

[0028] like Figure 1 and combined Figures 2 to 8 As shown, an upward folding door includes a folding door body 1, a door track 2, and a lifting drive mechanism 3. The two sides of the folding door body 1 are connected to the door track 2. The folding door body 1 includes a first door leaf 101 and a second door leaf 102. The upper part of the first door leaf 101 is connected to the door track 2 through a first hinge shaft 104, and the lower part of the first door leaf 101 is hinged to the second door leaf 102 through a second hinge shaft 105. The second door leaf 102 is hinged to the door track 2 through a third hinge shaft 105. The lifting drive mechanism 3 is placed inside one of the door tracks 2, and the output end of the lifting drive mechanism 3 is connected to one end of the third hinge shaft 106.

[0029] Furthermore, both ends of the second hinge shaft 105 are connected to first pulleys 107.

[0030] Furthermore, the two ends of the third hinge shaft 106 are connected to second pulleys 108.

[0031] The benefits of adopting a further technical solution are that the first pulley 107 and the second pulley 108 facilitate the lifting and lowering of the hinge shaft along the door rail 2.

[0032] Furthermore, the other end of the third hinge shaft 106 is connected to a shock absorber 109, which is made of rubber or silicone material.

[0033] The adoption of further technical solutions has the following benefits: the shock-absorbing block 109 plays a shock-absorbing role when the folding door body 1 descends and resets.

[0034] Furthermore, an auxiliary shock absorber 4 is installed inside another door track 2.

[0035] Furthermore, the auxiliary shock absorber 4 includes a shock absorber cylinder 401, a shock absorber rod 402, and a sliding plug 403. The shock absorber rod 402 is connected to the shock absorber cylinder 401 through the sliding plug 403. A first shock absorber spring 404 is provided between the sliding plug 403 and the shock absorber cylinder 401. A second shock absorber spring 405 is fitted onto the shock absorber rod 402.

[0036] The benefits of adopting further technical solutions include: the auxiliary shock absorber 4 further enhances its shock absorption and buffering function.

[0037] Furthermore, the third hinge shaft 106 is connected to a push-pull rod 110.

[0038] The benefits of adopting a further technical solution: the push-pull rod 110 facilitates manual pushing and pulling of the folding door 1.

[0039] Furthermore, a sound insulation and vibration damping pad 201 is provided inside the door track 2, and the sound insulation and vibration damping pad 201 is made of EPDM rubber.

[0040] The benefits of adopting further technical solutions include: the sound insulation and vibration damping pad 201 reduces the noise from the contact between the pulley and the door track, and the EPDM rubber has a good vibration damping effect.

[0041] Compared with the prior art, the present invention has the following advantages: The present invention is provided with a folding door body 1, a door track 2 and a lifting drive mechanism 3. The lifting drive mechanism 3 can drive the folding door body 1 to rise and fall along the door track 2. The auxiliary shock absorber 4 plays an auxiliary shock absorption role. The door track 2 is provided with a sound insulation and shock absorption pad 201, which can play a role in shock absorption, sound insulation and noise reduction.

[0042] Working principle: The two sides of the folding door body 1 are connected to the door rail 2. The folding door body 1 includes a first door leaf 101, a second door leaf 102 and a third door leaf 103. The upper part of the first door leaf 101 is connected to the door rail 2 through the first hinge shaft 104. The lower part of the first door leaf 101 is hinged to the second door leaf 102 through the second hinge shaft 105. The second door leaf 102 is hinged to the third door leaf 103 through the second hinge shaft 105. The third door leaf 103 is connected to the door rail 2 through the third hinge shaft 106. The lifting drive mechanism 3 is placed in one of the door rails 2. The output end of the lifting drive mechanism 3 is connected to one end of the third hinge shaft 106.

[0043] When the folding door 1 is opened, the lifting drive mechanism 3 is activated, pushing out the lifting cylinder, which in turn drives the third hinge shaft 106 to rise, thereby opening the folding door 1. When the folding door 1 is closed, the lifting drive mechanism 3 drives the lifting cylinder to fall, which in turn drives the third hinge shaft 106 to fall, thereby closing the folding door 1.

[0044] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
