Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, and in particular to a fastening structure for door and window profiles. Background Technology

[0002] As an important component of building envelope, the ease and stability of door and window installation directly affect construction efficiency and building quality. Currently, there are various ways to connect door and window profiles to installation tracks, with common fastening methods relying on direct screw fastening or pressure.

[0003] Furthermore, many existing fastening structures lack effective pre-positioning functions during installation, making it easy for the profiles to shift before final tightening, which inconveniences manual operation and adjustment. At the same time, traditional screw fastening methods require ample operating space for installation tools, making them difficult to implement in certain narrow or angled conditions, thus limiting their application.

[0004] Therefore, there is an urgent need to design a fastening structure for door and window profiles to solve the problems of lack of effective pre-positioning function in the existing technology, easy displacement of profiles before final fastening, and poor installation applicability. Utility Model Content

[0005] The purpose of this utility model is to provide a fastening structure for door and window profiles to solve the problems of lack of effective pre-positioning function in the prior art, easy displacement of profiles before final fastening, and poor installation applicability.

[0006] The technical solution of this utility model is: a door and window profile fastening structure, comprising: Door and window profiles, wherein hooks are provided on both opposite sides of the installation end of the door and window profiles; The mounting track is provided with two mounting hooks that are adapted to the two hooks respectively. The cavity between the two mounting hooks and the side wall of the mounting track forms a mounting groove for accommodating the mounting end. The mounting end slides into the mounting groove. A threaded component passes through the door / window profile and connects to the mounting track, thereby pressing and fixing the door / window profile in the mounting groove to prevent axial sliding.

[0007] Preferably, the door and window profile has a first cavity, a second cavity, and a third cavity arranged longitudinally on the same plane, and the door and window profile also has a through process hole that passes through the first cavity, the second cavity, and the third cavity; The through-holes are formed sequentially from top to bottom on the four cavity walls separating the first cavity, the second cavity, and the third cavity.

[0008] Preferably, one end of the threaded component is a fixed end, and a fixing hole adapted to the fixed end is provided on the mounting track at the corresponding installation position. The fixed end passes downward through the through process hole and is inserted into the fixing hole, thereby fixing the door and window profile on the mounting track.

[0009] Preferably, only one of the first process hole, the second process hole, the third process hole, and the fourth process hole is a threaded hole, and the threaded component has a threaded section, with the threaded hole and the threaded section being threadedly engaged.

[0010] Preferably, when the threaded hole is the second process hole, the threaded part is inserted from the top end face of the door and window profile or from the first cavity.

[0011] Preferably, when the threaded hole is the third process hole, the threaded component is inserted from the top end face of the door and window profile, or from the first cavity or the second cavity.

[0012] Preferably, when the threaded hole is the fourth process hole, the threaded component is inserted from the top end face of the door and window profile, or from the first cavity, the second cavity, or the third cavity.

[0013] Preferably, the fixed end is a smooth rod section, and the diameter of the fixed end is not greater than the diameter of the threaded rod section.

[0014] Preferably, the hook body has a stepped structure, the stepped structure includes a vertical force-bearing surface and a horizontal force-bearing surface, and the mounting hook has a mating surface that is adapted to the vertical force-bearing surface and the horizontal force-bearing surface.

[0015] Preferably, the inner diameter of all process holes except the threaded hole is larger than the diameter of the shank of the threaded component.

[0016] Compared with the prior art, the advantages of this utility model are: (1) By setting up hooks and mounting clips that cooperate with each other, the door and window profiles can be firmly pre-positioned on the installation track by the quick engagement of the hooks and clips, avoiding displacement before final tightening, facilitating manual operation and position adjustment, and solving the problem of lack of effective pre-positioning function in the prior art.

[0017] (2) By providing through process holes that penetrate multiple cavities, threaded parts can be inserted from the top end face of the profile or from the side cavity according to the actual working conditions, providing flexible and diverse installation paths for threaded parts. This design enables the structure to adapt to narrow or special angle installation environments, improving the applicability and convenience of installation.

[0018] (3) By setting a matching structure with threaded parts and through process holes, after the door and window profile slides to the predetermined position, the fixed end of the profile passes through the track fixing hole by screwing in the threaded part. At the same time, the threaded section is threadedly connected to the profile to form a stable pin locking structure. The operation is simple and the fastening is reliable. It effectively prevents the axial sliding of the profile and ensures the stability of the door and window profile installation. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to specific embodiments: like Figures 1 to 6 As shown, a door and window profile fastening structure includes a door and window profile 1, an installation track 2, and a threaded component 3.

[0021] The door and window profile 1 has hooks 14 on both sides of the installation end of the door and window profile 1. The hooks 14 have a stepped structure, which includes a vertical force-bearing surface and a horizontal force-bearing surface.

[0022] The mounting track 2 is provided with two mounting hooks 21 that are adapted to the two hook bodies 14 respectively. The cavity between the two mounting hooks 21 and the side wall of the mounting track 2 forms a mounting groove for accommodating the mounting end. The mounting end slides into the mounting groove. The mounting hooks 21 have mating surfaces adapted to the vertical force surface and the horizontal force surface.

[0023] Threaded part 3 passes through the door and window profile 1 and connects to the mounting track 2, thereby pressing and fixing the door and window profile 1 in the mounting groove to prevent it from sliding axially.

[0024] Align the mounting end of the door / window profile 1 with the mounting groove of the mounting track 2, align the hook 14 with the mounting clip 21, and apply force to engage them, allowing the door / window profile 1 to slide within the mounting groove. Once the door / window profile 1 has slid to the preset installation position, it is secured by the threaded component 3, thus completing the entire installation process.

[0025] like Figure 2 and Figure 3 As shown, the door and window profile 1 has a first cavity 11, a second cavity 12, and a third cavity 13 arranged longitudinally on the same plane. The door and window profile 1 also has through process holes 15 that penetrate the first cavity 11, the second cavity 12, and the third cavity 13. The through process holes 15 are formed sequentially from top to bottom on the four cavity walls that separate the first cavity 11, the second cavity 12, and the third cavity 13 as the first process hole 151, the second process hole 152, the third process hole 153, and the fourth process hole 154.

[0026] It should be noted that the three cavities shown in this embodiment are only a preferred option. The door and window profile 1 can also be designed with two, four, or other numbers of cavities according to actual needs. This multi-cavity design can not only effectively reduce the weight of the door and window profile 1, but also ensure the structural strength of the door and window profile 1 by forming a reinforcing rib structure between adjacent cavities.

[0027] like Figures 4 to 6 As shown, one end of the threaded component 3 is a fixed end 32, which is a smooth rod section, and the diameter of the fixed end 32 is not greater than the diameter of the rod section of the threaded component 3. A fixing hole adapted to the fixed end 32 is provided on the mounting track 2 at the corresponding installation position. The fixed end 32 passes downward through the through process hole 15 and is inserted into the fixing hole, thereby fixing the door and window profile 1 on the mounting track 2.

[0028] The design of the fixed end 32 having a smaller diameter than the threaded part 3 has two advantages. First, it facilitates the threaded part 3 to pass smoothly through the fixed hole and achieve rapid positioning. Second, since the fixed end 32 and the fixed hole are clearance fit, the diameter of the fixed hole on the mounting rail 2 can be reduced accordingly, which helps to maintain the structural strength of the mounting rail 2 and avoids weakening the load-bearing capacity of the mounting rail 2 due to excessively large openings.

[0029] As another implementation method, when the load-bearing capacity of the mounting rail 2 is large enough, the diameter of the fixed end 32 can be designed to be equal to the diameter of the threaded part 3 rod. In this case, no additional processing is required for the fixed end 32, which helps to reduce costs.

[0030] Among the first process hole 151, the second process hole 152, the third process hole 153 and the fourth process hole 154, only one hole is a threaded hole. The threaded part 3 is provided with a threaded section 31, and the threaded hole and the threaded section 31 are threadedly engaged.

[0031] When the threaded hole is the second process hole 152, the threaded part 3 is inserted from the top end face of the door and window profile 1 or from the first cavity 11.

[0032] When the threaded hole is the third process hole 153, the threaded part 3 is inserted from the top end face of the door and window profile 1, or from the first cavity 11 or the second cavity 12.

[0033] When the threaded hole is the fourth process hole 154, the threaded part 3 is inserted from the top end face of the door and window profile 1, or from the first cavity 11, the second cavity 12 or the third cavity 13.

[0034] like Figure 5 The diagram illustrates the installation scenario when the threaded component 3 is installed in the second cavity 12. The installation principle is the same when the threaded component 3 is inserted from another cavity. This method is applicable to situations where the threaded component 3 cannot be operated from the top. It should be noted that to ensure the threaded component 3 can be smoothly inserted into the cavity, the height of the cavity where the threaded component 3 is installed should be greater than the overall height of the threaded component 3.

[0035] In the through process hole 15, the inner diameter of all process holes except the threaded hole is larger than the shank diameter of the threaded part 3.

[0036] Working principle: First, the hook 14 on the door / window profile 1 engages with the mounting hook 21 on the mounting track 2, pre-positioning the door / window profile 1 and allowing it to slide axially along the mounting track 2 within the mounting groove to adjust to the installation position. Then, the threaded component 3 is screwed into the through-hole 15, with its lower fixed end 32 passing through the fixed hole of the mounting track 2. Simultaneously, its threaded section 31 connects with the pre-drilled threaded hole on the door / window profile 1, forming a stable whole with the entire threaded component 3. At this point, the fixed end 32 passing through the fixed hole of the mounting track 2 acts like a pin, locking the door / window profile 1 and the threaded component 3 together on the mounting track 2, preventing axial sliding of the door / window profile 1 relative to the mounting track 2, thus achieving an effective fastening effect.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
