Abstract
Description
Technical Field
[0001] This utility model relates to the field of keel connector technology, and more specifically, to a secondary keel connector. Background Technology
[0002] Light steel keel is made of cold-formed light steel material, commonly galvanized steel sheet. It typically has a C-shaped or U-shaped cross-section and possesses high strength and stability. Light steel keel is widely used in interior decoration for partition walls, suspended ceilings, soundproof walls, lightweight wall structures, and other building structures. It provides a lightweight, sturdy, and reliable support system for installing gypsum board, sound insulation materials, and other decorative materials.
[0003] Currently, the keel is generally a vertical board with a horizontal groove. This grooving method is relatively simple, but it reduces the overall load-bearing capacity of the vertical board and reduces the practicality of the keel in terms of load-bearing.
[0004] Therefore, in view of this, the existing structure is studied and improved to provide a secondary keel connector, in order to achieve a more practical purpose. Utility Model Content
[0005] 1. Technical problems to be solved
[0006] In view of the problems existing in the prior art, the purpose of this utility model is to provide a secondary keel connector that can form a relatively three-dimensional secondary keel connector, improve the load-bearing capacity of the secondary keel connector, and effectively improve the stability of the secondary keel connector when connected with other structures.
[0007] 2. Technical Solution
[0008] To solve the above problems, the present invention adopts the following technical solution.
[0009] A secondary keel connector includes two grooved connectors that combine to form an L-shaped structure. Each grooved connector includes a base plate, a left side plate, and a right side plate. The left side plate and the right side plate have the same structure and are respectively fixed to both sides of the base plate. The ends of the base plates on the two grooved connectors are fixed to each other.
[0010] The left upright plate has a groove near the bottom plate, and a slot is provided in the groove, with a locking tooth fixedly installed inside the slot.
[0011] The side of the secondary keel connector is fitted with a keel accessory. The keel accessory has several connection holes and several locking holes. The connection holes are aligned with the corresponding connection holes, and the locking teeth are engaged in the corresponding locking holes.
[0012] Furthermore, the length of the base plate on the horizontally arranged groove-shaped connector is greater than the length of the base plate on the vertically arranged groove-shaped connector.
[0013] Furthermore, the bottom ends of the left and right vertical plates of the vertically arranged groove connector are cut to form a right-angled trapezoidal structure.
[0014] Furthermore, the depth of the groove is equal to the depth of the slot.
[0015] Furthermore, the connecting holes and the connecting holes have the same cross-sectional specifications.
[0016] Furthermore, both sides of the keel fitting are fixedly provided with right-angled folded edges, and several of the card holes are evenly distributed on the two right-angled folded edges;
[0017] The right-angled folded edge is inserted into the slot.
[0018] 3. Beneficial effects
[0019] Compared with existing technologies, the advantages of this utility model are:
[0020] This solution uses two mutually fixed groove-shaped connectors to form an L-shaped secondary keel connector. The left and right upright plates of the secondary keel connector are provided with grooves and holes in the grooves. At the same time, a four-centimeter retaining groove is provided at the groove position. This forms a relatively three-dimensional secondary keel connector, which improves the load-bearing capacity of the secondary keel connector and effectively improves the stability of the secondary keel connector when connected with other structures.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0032] Example
[0033] Please see Figure 1 - Figure 4 A secondary keel connector includes two grooved connectors 1, which are combined to form an L-shaped structure. Each grooved connector 1 includes a base plate 2, a left vertical plate 3, and a right vertical plate 4. The left vertical plate 3 and the right vertical plate 4 have the same structure and are respectively fixed to both sides of the base plate 2. The ends of the base plate 2 on the two grooved connectors 1 are fixed to each other.
[0034] A groove 301 is provided on the left upright plate 3 near the bottom plate 2, and a slot 302 is provided on the groove 301, and a locking tooth 303 is fixedly installed inside the slot 302.
[0035] The side of the secondary keel connector is fitted with a keel accessory 5. The keel accessory 5 has several connection holes 501 and several locking holes 502. The connection holes 302 are aligned with the corresponding connection holes 501, and the locking teeth 303 are engaged in the corresponding locking holes 502.
[0036] See Figure 3 , Figure 4 Specifically, the length of the base plate 2 on the horizontally arranged groove-shaped connector 1 is greater than the length of the base plate 2 on the vertically arranged groove-shaped connector 1.
[0037] Specifically, the bottom ends of the left upright plate 3 and the right upright plate 4 of the vertically arranged groove connector 1 are cut to form a right-angled trapezoidal structure.
[0038] By limiting the difference in length between the two base plates 2, and by cutting the left vertical plate 3 and the right vertical plate 4 of the grooved connector 1, the two grooved connectors 1 are prevented from colliding with each other when forming the L-shaped structure of the secondary keel connector.
[0039] See Figure 3 , Figure 4 Specifically, the depth of the groove 301 is equal to the depth of the slot 302.
[0040] By limiting the depth of the groove 301 and the slot 302, the left upright plate 3 and the right upright plate 4 are both guaranteed to form a relatively three-dimensional structure, thereby enhancing the load-bearing capacity of the left upright plate 3 and the right upright plate 4.
[0041] See Figure 1 Specifically, the cross-sectional specifications of connecting hole 302 and connecting hole 501 are the same.
[0042] This ensures that connection hole 302 and connection hole 501 can be aligned.
[0043] See Figure 1 Specifically, both sides of the keel accessory 5 are fixedly provided with right-angled folded edges 503, and several locking holes 502 are evenly distributed on the two right-angled folded edges 503;
[0044] The right-angle folded edge 503 is inserted into the slot 302.
[0045] By inserting the right-angle folded edge 503 into the slot 302 and then using the tooth 303 to pass through the hole 502, a stable connection can be formed between the secondary keel connector and the keel accessory 5.
[0046] Working principle:
[0047] This type of secondary keel connector consists of a three-dimensional structure composed of two grooved connectors 1, which can effectively improve the load-bearing capacity of the secondary keel connector. At the same time, through the slots 302 and teeth on the left and right upright plates 3 and 4 of each grooved connector 1, a stable engagement can be formed with the right-angle folded edge 503 and the locking hole 502 of the keel accessory 5. In addition, the connecting hole 302 can be aligned with the connecting hole 501 of the keel accessory 5, and the stability of the connection between the two can be further improved by adding bolts.
[0048] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
