Description

Technical Field

[0001] The utility model relates to the technical field of bi-door frames, in particular to a novel door frame structure. Background Art

[0002] Currently, the aluminum alloy double doors used in homes are mainly composed of door panels and square aluminum alloy door frames installed on the outside of the door panels. The double doors of this structure are mainly installed in the metal frame by the aluminum alloy door frames on the outside of the door panels.

[0003] Although the existing aluminum alloy double-door bodies can be reliably installed with the help of aluminum alloy door frames, a retaining edge is reserved on one of the door bodies of the double-door body to ensure that the two door bodies on the double-door body are reliably fitted and sealed after closing. However, due to the existence of the retaining edge, the door body that closes first cannot rotate relative to the door body that closes subsequently, making the opening and closing method of the double-door body relatively simple and not flexible enough to use. Utility Model Content

[0004] (1) Technical issues to be resolved

[0005] The technical problem to be solved by the present invention is to provide a new door frame structure based on the current status of the existing technology, which can ensure the convenient rotation and opening and closing of the first closed door body relative to the second closed door body under the premise of achieving reliable closure and sealing of the two door bodies of the double-door.

[0006] (2) Technical solution

[0007] The present invention is realized through the following technical scheme: the present invention proposes a novel door frame structure, comprising an aluminum edge of a door frame, two mounting sleeves symmetrically arranged on the upper and lower sides of an outer corner of the aluminum edge of the door frame, a flip limit assembly commonly installed between the two mounting sleeves, the flip limit assembly comprising a connecting shaft installed in the two mounting sleeves, a wear-resistant rotating sleeve installed at one end of the connecting shaft, an aluminum baffle installed on the outside of the wear-resistant rotating sleeve, a wool strip installed on one side wall of the aluminum baffle, a telescopic spring installed in both ends of the connecting shaft, a clamping bead installed at the end of the telescopic spring facing away from the connecting shaft, a clamping hole opened on the mounting sleeve, and a spiral spring installed in the mounting sleeve at the end of each connecting shaft, and a decorative cover is also installed on the end of the mounting sleeve facing away from the connecting shaft.

[0008] Furthermore, the aluminum edge of the door frame has an arc-shaped groove structure located at the mounting sleeve, a T-shaped plug is installed on the side of the mounting sleeve facing away from the aluminum baffle, a fixing bolt is installed on the upper part of the mounting sleeve, and a T-shaped slot is provided on the aluminum edge of the door frame at the position that cooperates with the T-shaped plug.

[0009] By adopting the above technical solution, the fixing bolt is mainly used to achieve reliable limiting of the T-shaped plug block, so as to achieve reliable installation of the mounting sleeve on the aluminum edge of the door frame.

[0010] Furthermore, the fixing bolt passes through the installation sleeve and the aluminum side wall of the door frame, and the fixing bolt is screwed to the aluminum side wall of the door frame.

[0011] By adopting the above technical solution, it can be ensured that the installation sleeve is reliably installed and fixed under the action of the fixing bolt.

[0012] Furthermore, the wear-resistant rotating sleeve is made of nylon, and the wear-resistant rotating sleeve is plugged and fixed to the connecting shaft.

[0013] By adopting the above technical solution, the wear resistance of the wear-resistant rotating sleeve can be ensured, so that the wear-resistant rotating sleeve can be used stably for a long time, and at the same time, the aluminum baffle can rotate synchronously with the connecting shaft.

[0014] Furthermore, the aluminum baffle is plugged and fixed to the wear-resistant rotating sleeve, and a gap is reserved between the end of the aluminum baffle and the aluminum edge of the door frame.

[0015] By adopting the above technical solution, since the rear-closing double-door body will also be blocked and limited by the lower side of the installation frame, the rear-closing double-door body can be auxiliary-blocked with the help of the aluminum baffle.

[0016] Furthermore, the portion of the connecting shaft where it is connected to the telescopic spring is a concave structure, the telescopic spring is hooked to the connecting shaft, and the telescopic spring is hooked to the card bead.

[0017] By adopting the above technical solution, when the card bead is stuck in the card hole under the action of the telescopic spring, the position of the aluminum baffle is relatively fixed. At this time, the aluminum baffle can assist in blocking the rear-closed door body. When it is necessary to open the first-closed door body without opening the rear-closed door body, as the pulling force acting on the first-closed door body continues to increase, the card bead will retract into the card hole. At this time, the telescopic spring is compressed. As the aluminum baffle flips under the blocking action of the rear-closed door body, the connecting shaft will rotate together. At this time, the spiral spring is compressed. When the first-closed door body is opened relative to the rear-closed door body, the aluminum baffle will be reset under the action of the spiral spring. After the aluminum baffle is reset, the card bead is just opposite the card hole, thereby realizing the reset of the card bead.

[0018] Furthermore, one end of the volute spring is plugged into the connecting shaft, and the other end of the volute spring is plugged into the mounting sleeve.

[0019] By adopting the above technical solution, the spiral spring is mainly used to realize the automatic reset of the aluminum baffle after flipping, so as to ensure the normal use of the corresponding door body.

[0020] (3) Beneficial effects

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In order to solve the problem that the existing aluminum alloy double-leaf door body can be reliably installed with the help of aluminum alloy door frame, a retaining edge is reserved on one of the door bodies of the double-leaf door to achieve reliable sealing of the two door bodies after closing, and the existence of the retaining edge will make the door body closed first unable to rotate relative to the door body closed later, making the opening and closing method of the double-leaf door relatively simple and inflexible to use, the utility model installs a mounting sleeve on the upper and lower sides of the aluminum edge of the door frame on one door body of the aluminum alloy double-leaf door respectively, and installs a flip limit assembly between the two mounting sleeves, and at the same time takes The retaining edge of the other door body on the aluminum alloy double-leaf door eliminates the need for the door frame structure of this structure to not only block the rear-closing double-leaf door body under the action of the limited aluminum baffle when in use, but also can retract the card bead into the card hole by pulling the first-closed double-leaf door body when the rear-closed door body does not move, so that the aluminum baffle can be rotated outward 90 degrees, ensuring that the first-closed door body is conveniently opened relative to the rear-closed door body. After opening, the aluminum baffle will be reset under the action of the spiral spring, ensuring the subsequent normal limiting use of the rear-closed door body, thereby making the opening and closing of the double-leaf door body more flexible.
