Description

Technical Field

[0001] This utility model relates to the field of ceiling keel connection technology, and in particular to a ceiling keel fixing structure. Background Technology

[0002] With the rapid development of the building decoration industry, lightweight steel keel gypsum board ceilings are widely used in various building interior spaces due to their advantages such as light weight and convenient construction. As the core load-bearing component of the ceiling frame, the stability and adaptability of the connection structure of the keel directly determine the overall quality and construction efficiency of the ceiling.

[0003] In existing technologies, such as the Chinese utility model patent with authorization announcement number CN219710724U, a snap-fit ​​connector, a keel installation structure, and a ceiling installation structure are disclosed. This snap-fit ​​connector achieves vertical connection of the keel through a combination design of multiple snap-fit ​​bodies (first snap-fit ​​body, second snap-fit ​​body, and third snap-fit ​​body). However, this type of connection structure has a relatively simple function and is only suitable for connecting keels that intersect vertically, which has obvious limitations in actual construction. In actual construction, there are often situations where there is a gap between the ends of two secondary keels, requiring the addition of a short secondary keel for intermediate fixation, and situations where the end of a straight keel needs to be connected to the side of a circular keel to adapt to a special shape. This snap-fit ​​connector cannot achieve the above connection operations and requires additional special connectors. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a ceiling keel fixing structure, which solves the technical problem that most physiotherapy patches are designed for single use, resulting in excessively high long-term use costs.

[0005] One of the objectives of this utility model is achieved through the following technical solution: It includes two sets of keel members and a connector for connecting the two sets of keel members. The keel members are provided with an opening groove and a bearing edge that bends inward at the upper end of the groove. The connector includes: A support plate, wherein the support plate is disposed within an opening groove; Two sets of snap-fit ​​brackets are respectively disposed at both ends of the support plate, and the outer ends of the snap-fit ​​brackets are... The part is provided with a first snap-fit ​​part that engages with the opening slot; the lower end of the snap-fit ​​frame is provided with a snap-fit ​​groove, the inner wall of the snap-fit ​​groove is provided with an elastic abutment part, and the snap-fit ​​groove is configured to selectively engage with the groove wall of a set of keel members, or engage with the adjacent groove wall of two sets of coaxially connected keel members. When the snap-fit ​​frame engages with the groove wall of the keel component, the upper end of the elastic abutment portion engages with the lower side of the bearing edge.

[0006] Based on the above technical solution, the present invention is further described as follows: The snap-fit ​​frame includes a first plate and a second plate arranged in parallel, and a connecting plate disposed between the two ends of the first plate and the second plate. The snap-fit ​​groove extends through the connecting plate along the extension direction of the first plate and the second plate, and the support plate is connected to the second plate.

[0007] As a further optimization of this utility model, the second plate body includes two sets of sub-plates, and a gap is provided between the two sets of sub-plates.

[0008] As a further optimization of this utility model, the elastic abutment part is provided with several groups, including an arc-shaped metal plate, the lower end of the arc-shaped metal plate is connected to the lower end of the second plate, the middle part of the arc-shaped metal plate is fitted with the first plate, and the upper end of the arc-shaped metal plate extends towards the upper end of the snap-fit ​​groove.

[0009] As a further optimization of this utility model, the first snap-fit ​​part includes two sets of snap-fit ​​plates arranged in parallel. One end of the snap-fit ​​plate is connected to the first plate body, and the other end of the snap-fit ​​plate is provided with a guide arc-shaped part. The height of the snap-fit ​​plate is the same as the height from the lower side of the bearing edge to the bottom of the opening groove.

[0010] As a further optimization of this utility model, the snap-fit ​​frame is configured as an integrally stamped metal plate.

[0011] As a further optimization of this utility model, the first plate is provided with a first slot that matches the shape of the snap-fit ​​plate, and the snap-fit ​​plate is formed by bending the plate portion in the first slot in a direction away from the support plate.

[0012] As a further optimization of this utility model, the second plate is provided with a second slot that matches the shape of the elastic abutment part, and the elastic abutment part is formed by bending the plate part in the second slot toward the direction close to the first plate.

[0013] As a further optimization of this utility model, the upper end of the arc-shaped metal plate is provided with anti-slip teeth that protrude into the inside of the snap-fit ​​groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is used to complete the load-bearing support of the ceiling frame required for ceiling construction through keel components. It is used to achieve the function of adapting a single structure to two arrangement methods of keel components, namely vertical intersection or coaxial docking, through connectors. It significantly improves construction flexibility and scenario applicability, and reduces the types and quantities of special connectors.

Detailed Implementation

[0017] Below, in conjunction with the appendix Figure 1 To be continued Figure 5 The present invention will be further described in detail below, along with specific implementation methods. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] A ceiling keel fixing structure includes two sets of keel components 1 and connectors for connecting the two sets of keel components 1. The connectors include a support plate 2 and two sets of snap-fit ​​frames 3 disposed at both ends of the support plate. The keel components 1 are used to provide load-bearing support for the ceiling skeleton required for ceiling construction. The connectors are used to adapt a single structure to the arrangement of two types of keel components 1, namely vertically intersecting or coaxially connected, significantly improving construction flexibility and scenario applicability, and reducing the types and quantities of special connectors. Specifically, the support plate 2 provides stable structural support for the two sets of snap-fit ​​frames 3, ensuring connection stability. The snap-fit ​​frames 3 enable rapid positioning of the connection between the two sets of keel components 1 and reliable snap-fit ​​of the load-bearing edges 14 of the two sets of keel components 1, improving assembly efficiency and connection stability.

[0019] Please refer to the attached document. Figure 1 and attached Figure 2 The keel component 1 can be, but is limited to, a secondary keel in a light steel keel for slings. The keel component 1 is made of aluminum profile and has an opening slot 13 and a bearing edge 14 bent inwards at the upper end of the slot. The secondary keel is fixed to the lower end of the main keel through its opening slot 13. During the installation of the secondary keel, one set of keel components 1 needs to be connected to another set of keel components 1. The two sets of keel components 1 include a first keel 11 and a second keel 12. Typical applications include connecting the end of the first keel 11 to the side wall of the second keel component, or coaxially arranging the first keel 11 and the second keel 12. A short keel is added between the two keels 12. Currently, during ceiling construction, workers need to use tools to pre-bend the middle of the short keel before inserting its two ends into the first and second keels 12 to be connected. The connection structure provided in this embodiment eliminates the need for this bending step, enabling rapid installation of the short keel. In addition, this structure can also adapt to the reliable connection between the end of a straight keel and the side wall of an arc-shaped keel. That is, the first keel 11 is a straight keel, the second keel 12 is an arc-shaped keel, and the end of the first keel 11 is fixedly connected to the groove wall 15 of the second keel 12, demonstrating good adaptability and ease of construction.

[0020] For details, please refer to the appendix. Figure 1 The support plate 2 is disposed in the opening groove 13. The support plate 2 is rectangular and its width is adapted to the width of the opening groove 13 of the keel component 1. It is accommodated on the bottom surface inside the opening groove 13, thereby realizing the positioning of the support plate 2 in the opening groove 13, restricting the lateral displacement of the support plate 2 along the opening groove 13, and improving the fit stability of the connector and the keel component 1. It and the snap-fit ​​frame 3 are integrally molded to ensure the structural integrity of the connection between the two. The snap-fit ​​frame 3 provides a stable bottom support reference.

[0021] Please refer to the attached document. Figure 1 and attached Figure 3The two sets of snap-fit ​​frames 3 are respectively disposed at both ends of the support plate 2. Specifically, the snap-fit ​​frame 3 includes a first plate 31 and a second plate 32 arranged in parallel, and a connecting plate 33 disposed between the two ends of the first plate and the second plate. The support plate 2 is connected to the second plate 32. The first plate 31 is a straight plate. The outer end of the snap-fit ​​frame 3 is provided with a first snap-fit ​​part 34 that snaps into the opening slot 13. In some embodiments, the first snap-fit ​​part 34 is snap-fitted into the opening slot 13 of the first keel 11. Specifically, the first snap-fit ​​part 34 includes two sets of parallel snap-fit ​​plates 341. One set of the snap-fit ​​plates 341 is connected to the first plate 31. The other set of the snap-fit ​​plates 341 is provided with a guide arc-shaped part 3411. The middle part of the snap-fit ​​plate 341 is rectangular. The height of the middle part of the snap-fit ​​plate 341 is the same as the height from the lower side of the bearing edge 14 to the bottom of the opening slot 13. The two sets of snap-fit ​​plates 341 are respectively inserted between the bearing edge 14 and the bottom of the slot on both sides of the opening slot 13, thereby realizing the fixed connection between the snap-fit ​​frame 3 and the first keel 11.

[0022] Please refer to the attached document. Figure 3 Appendix Figure 4 and attached Figure 5 The lower end of the snap-fit ​​frame 3 is provided with a snap-fit ​​groove 35 extending from the lower end of the snap-fit ​​frame to the upper end of the snap-fit ​​frame. The snap-fit ​​groove 35 penetrates the connecting plate 33 along the extending direction of the first plate 31 and the second plate 32, thereby realizing the insertion function of the groove walls 15 of the first keel 11 and the second keel 12. The snap-fit ​​groove 35 is configured to selectively snap-fit ​​with the groove walls 15 of a set of keel parts 1, that is, the groove wall 15 of the second keel 12 completely occupies the space in the snap-fit ​​groove 35, or snap-fit ​​with the adjacent groove walls 15 of two sets of coaxially connected keel parts 1, that is, the first keel 11 and the second keel 12 are coaxially arranged. A short keel is provided between the first keel 11 and the second keel 12. The first keel 11 and the short keel each occupy half of the space of the corresponding snap-fit ​​groove 35, and the second keel 12 and the short keel each occupy half of the space of the corresponding snap-fit ​​groove 35. The height of the snap-fit ​​bracket is higher than the height of the opening groove 13 of the first keel 11 and the second keel 12. The height of the snap-fit ​​groove 35 is the same as the height of the groove wall 15 of the first keel 11. When the groove wall 15 of the first keel 11 or the second keel 12 extends into the snap-fit ​​groove 35, that is, when the support plate 2 is in contact with the bottom of the opening groove 13, the bottoms of the first keel 11 and the second keel 12 are at the same height.

[0023] Please refer to the attached document. Figure 3 Appendix Figure 4 and attached Figure 5The inner wall of the snap-fit ​​groove 35 is provided with an elastic abutment part 36. Specifically, the elastic abutment part 36 is disposed on the second plate 32. When the snap-fit ​​frame 3 is snapped into place with the groove wall 15 of the keel member 1, the upper end of the elastic abutment part 36 abuts against the lower side of the bearing edge 14, and the middle part of the elastic abutment part 36 abuts against the groove wall 15 of the keel member 1. Through the abutment between the end of the upper elastic abutment part 36 and the lower side of the bearing edge 14, and the abutment between the middle part of the elastic abutment part 36 and the groove wall 15 of the keel member 1, a bidirectional elastic clamping force is formed, realizing the snap-fit ​​node. The tight fit enhances the anti-loosening ability of the connection structure. Specifically, the elastic abutment part 36 is provided with several sets, including an arc-shaped metal plate 361. The lower end of the arc-shaped metal plate 361 is connected to the lower end of the second plate 32, and the middle part of the arc-shaped metal plate 361 is fitted with the first plate 31. The upper end of the arc-shaped metal plate 361 extends towards the upper end of the snap-fit ​​groove 35. This extension design of the upper end of the arc-shaped metal plate towards the upper end of the snap-fit ​​groove 35 forms a guiding effect during the insertion of the keel part 1 into the snap-fit ​​groove 35, reducing the difficulty of installation alignment and realizing a quick snap-fit ​​guiding function. The upper end of the arc-shaped metal plate 361 is provided with anti-slip teeth protruding towards the inside of the snap-fit ​​groove 35, thereby increasing the contact friction, limiting the relative displacement between the snap-fit ​​frame 3 and the keel part 1, realizing the anti-detachment limiting function, and improving the vibration resistance stability of the connection node.

[0024] Please refer to the attached document. Figure 3 Appendix Figure 4 and attached Figure 5 The second plate 32 includes two sets of sub-plates 321. The two sets of second plates 32 are respectively connected to the two ends of the first plate 31 through the connecting plate 33. A gap is provided between the two sets of sub-plates 321. The connecting plate 33 is provided at one end of the two sets of sub-plates 321, and a bending part 3211 is provided at the other end of the sub-plate 321. The bending part 3211 abuts against the first plate 31 to design the gap between the two sets of sub-plates 321. When adapting to the connection scenario of the arc-shaped keel 1, it provides the first plate 31 with a flexible deformation space, so that the first plate 31 can adaptively adjust with the curvature of the arc-shaped keel 1 under the action of external force, realize the smooth docking function of the arc-shaped keel 1 and the straight keel 1, break through the limitation of traditional rigid structures that can only adapt to straight keels, and improve the adaptability of the connector to irregular ceiling scenarios.

[0025] Please refer to the attached document. Figure 3 Appendix Figure 4 and attached Figure 5The first plate 31 is provided with a first slot 311 that matches the shape of the snap-fit ​​plate 341, and the second plate 32 is provided with a second slot 322 that matches the shape of the elastic abutment part 36. The snap-fit ​​plate 341 is bent from the plate portion in the first slot 311 away from the support plate 2, and the elastic abutment part 36 is bent from the plate portion in the second slot 322 towards the first plate 31. This eliminates the connection gap and strength loss caused by separate assembly, strengthens the overall structural strength of the connector, improves the fracture resistance of the snap-fit ​​plate 341 and the deformation durability of the elastic abutment part 36, simplifies the processing steps and material costs of the connector, improves the production efficiency of the connector, and enhances the feasibility and economy of standardized production of the product.

[0026] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
