Description

Technical Field

[0001] This utility model relates to the field of door manufacturing technology, and in particular, to a connection structure between a door leaf and an aluminum profile. Background Technology

[0002] A snap-fit ​​door is a door whose edges are secured by profiles. In actual production, due to processing errors, the openings between the door leaf and the profiles may not match, ultimately preventing them from being securely installed.

[0003] Currently, Chinese patent CN217632091U discloses a door edging fixing structure, including a door leaf, a edging, and a sliding nut. The door leaf has a first through hole and a mounting groove on its side. The sliding nut is slidably fitted into the mounting groove, specifically sliding from the mounting groove towards the first through hole, thereby aligning the third and fourth through holes on the sliding nut with the first through hole. The first through hole is particularly fitted as an oblong hole, allowing for fine adjustment of the fixing points on the side for securing the edging through the sliding of the sliding nut, thus reducing the precision requirements for door leaf manufacturing.

[0004] However, the sliding guide direction of the aforementioned mounting groove is consistent with the length direction of the oblong hole. This means that the fixing point used to secure the retaining edge can only be adjusted along the sliding guide direction of the mounting groove. Furthermore, when there is a lateral machining error between the retaining edge and the door leaf, it can still easily lead to a failure to securely install the retaining edge. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a connection structure between the door leaf and the aluminum profile.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A connection structure between a door leaf and an aluminum profile is disclosed. A through groove is provided on the side of the door leaf, and a sliding nut is fastened within the through groove. A through hole is also provided on the side of the door leaf next to the through groove. The through groove and the through hole are arranged along the length of the side of the door leaf, and both the through hole and the through groove extend along the width of the side of the door leaf to provide lateral movement freedom for the sliding nut. The diameter of the connecting hole of the sliding nut is smaller than the width of the through hole to provide longitudinal movement freedom for the sliding nut.

[0008] Preferably, the longitudinal axis of the through hole is the same as that of the through groove.

[0009] Preferably, the two connecting holes on the slip nut have substantially the same diameter.

[0010] Preferably, at least one of the two snap edges of the slip nut has a bent portion at its end, the bent portion being bent away from the other snap edge, thereby forming a gap between the two snap edges.

[0011] Preferably, the bent portion is formed only on the threaded edge.

[0012] Preferably, the through hole is a waist-shaped hole.

[0013] Preferably, the bent portion of the slip nut has a cut.

[0014] The beneficial effects of this utility model are: the sliding nut can slide laterally along the through groove, thereby changing the position of the fixing point used to fix the clamping edge in the lateral direction; and since the diameter of the connecting hole of the sliding nut is smaller than the width of the through hole, the sliding nut can also move longitudinally to change the longitudinal position of the fixing point. Compared with the prior art, the through groove of this utility model does not require an additional guide groove, and can meet the adjustment of the clamping edge fixing point in both the lateral and longitudinal directions, making it less likely that the door leaf and the clamping edge cannot be securely installed.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] A connection structure between a door leaf and an aluminum profile is disclosed, wherein a through groove 2 and a through hole 4 are provided on the side 1 of the door leaf, similar to those in the prior art, and the through groove 2 and the through hole 4 can be arranged sequentially along the length direction of the side 1, for example. A sliding nut 3 is correspondingly fastened in the through groove 2, and the different way in which the sliding nut 3 and the through groove 2 are matched will be described in detail below.

[0021] Specifically, both the through hole 4 and the through groove 2 extend along the width direction of the side 1, so that the sliding nut 3 can move laterally along the through groove 2; in addition, the diameter of the connecting hole 10 of the sliding nut 3 is also adapted to be smaller than the width of the through hole 4, so that the sliding nut 3 can also move longitudinally.

[0022] Compared with the prior art, the through groove 2 disclosed herein does not require an additional guide groove to guide the sliding of the sliding nut 3. That is, the sliding nut 3 can slide along the through groove 2 by engaging with the side 1 at the through groove 2. Furthermore, based on the unique arrangement of the through groove 2 and the through hole 4, the sliding nut 3 disclosed herein can move in both horizontal and vertical directions to achieve a wider range of adjustment of the position of the locking point.

[0023] Specifically, the edge clamp can be an aluminum profile or other material.

[0024] In some embodiments, the through hole 4 and the through groove 2 are adapted to have the same longitudinal axis, which enables the through hole 4 and the through groove 2 to provide a relatively consistent lateral travel for the slip nut 3.

[0025] The slip nut 3 may specifically include two snap edges 5, which are formed with a U-shaped cross section. Connecting holes 10 are provided on both snap edges 5. Due to the unique arrangement of the through groove 2 and through hole 4 disclosed herein, the two connecting holes 10 can be adapted to have basically the same diameter. This makes the machining process of the connecting holes 10 simpler, because there is no need to process the two connecting holes 10 with different processes.

[0026] The main reason is that in the prior art, the sliding nut 3 needs to slide along the guide groove so that the connecting hole 10 is opposite to the through hole 4. However, the connecting hole 10 disclosed herein always moves within the projection range of the through hole 4, and it is not easy for the connecting hole 10 and the through hole 4 to be misaligned and blocked. Therefore, there is no need to increase the diameter of the connecting hole 10.

[0027] In some embodiments, at least one of the two snap-fit ​​edges 5 has a bent portion 6 at its end, and the bent portion 6 is bent away from the side of the other snap-fit ​​edge 5, thereby forming a notch 7 between the ends of the two snap-fit ​​edges 5. It can be understood that due to the presence of the notch 7, the snap-fit ​​nut 3 will be more conveniently engaged in the through groove 2. In addition, the two snap-fit ​​edges 5 can also be adapted to have a large mutual clamping force, and under the guidance of the notch 7, the two snap-fit ​​edges 5 will automatically open and clamp the inner and outer surfaces of the side 1.

[0028] For example, the bent portion 6 can preferably be adapted to be formed only on the snap edge 5 with the threaded portion 8 of the slip nut 3, while the other snap edge 5 can maintain a relatively straight contact surface to fit with the snap edge, so that the slip nut 3 and the snap edge do not interfere with each other, resulting in an unexpected gap after the snap edge and the side 1 are fastened.

[0029] In a specific example, the through groove 2 can be a square groove, while the through hole 4 is preferably an oblong hole. In addition, the bent portion of the sliding nut 3 also has a notch 9 to prevent the sliding nut 3 from cracking during the bending process.

[0030] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
