Description

Technical Field

[0001] This utility model relates to the field of keel technology, and in particular to a card-type keel and keel assembly. Background Technology

[0002] Clip-on keel is a new type of building material. With the development of my country's modernization, clip-on keel has been widely used in hotels, airport terminals, passenger stations, train stations, theaters, shopping malls, factories, office buildings, renovation of old buildings, interior decoration and other places in recent years.

[0003] However, reference Figure 1 Existing clip-type keel systems typically include a keel base plate 1', a keel base plate 1' for connecting suspension rods 2', keel sidewalls 3' on both sides of the keel base plate 1', and a positioning edge 4' on the side of the keel sidewall 3' away from the keel base plate 1', with a slot 5' for connecting the covering keel 6'. However, because the positioning edge 4' of the clip-type keel needs to engage with the covering keel 6', it is often subjected to great stress. This causes the positioning edge 4' to be prone to uneven stress on the keel sidewalls 3' on both sides of the keel base plate 1' (specifically, the positioning edges 3' on both sides) during installation or after a period of use, resulting in deformation, slippage, and thus safety hazards. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes a clip-type keel and keel assembly that can avoid the positioning clip edge from twisting, expanding outward or shrinking due to uneven force or excessive local stress.

[0005] This utility model is achieved through the following technical solution.

[0006] A clip-on keel, the clip-on keel including a first keel side plate and a second keel side plate disposed opposite each other, and further comprising:

[0007] The first snap-fit ​​side wing plate is disposed on the lower side of the first keel side plate;

[0008] The second snap-fit ​​side wing plate is disposed on the lower side of the second keel side plate;

[0009] A connecting base plate is configured to connect the lower side of the first snap-fit ​​side wing plate and the lower side of the second snap-fit ​​side wing plate;

[0010] The connecting base plate has several disconnected sections, and the first snap-fit ​​side wing plate and the second snap-fit ​​side wing plate have several snap-fit ​​grooves along their extension direction. The snap-fit ​​grooves correspond one-to-one with the disconnected sections and extend to the disconnected sections to form snap-fit ​​channels for connecting the keel.

[0011] As a further improvement of this utility model, a connecting groove is formed between the first keel side plate and the second keel side plate, and the connecting groove has an opening that allows the connector to slide along its extension direction.

[0012] As a further improvement of this utility model, the inner edges of the first keel side plate and the second keel side plate are provided with limiting edges that bend or curl into the connecting groove, and the limiting edges cooperate with the connecting parts to achieve hanging and locking.

[0013] As a further improvement of this utility model, a keel base plate is provided between the first keel side plate and the second keel side plate, and the first snap-fit ​​side wing plate and the second snap-fit ​​side wing plate are provided on the underside of the base plate.

[0014] As a further improvement of this utility model, the keel base plate includes a first base plate and a second base plate. The first base plate is used to connect the first keel side plate and the first snap-fit ​​side wing plate, and the second base plate is used to connect the second keel side plate and the second snap-fit ​​side wing plate.

[0015] Based on a concept, this utility model also discloses a keel assembly, including a covered keel and a clip-type keel as described above.

[0016] As a further improvement of this utility model, it also includes a connector disposed on the card-type keel. The connector includes two connecting plates spaced apart, a connecting beam disposed between the two connecting plates, and a snap-fit ​​part disposed on the lower side of the connecting plate for sliding into the first keel side plate and the second keel side plate. The snap-fit ​​part is provided with a snap-fit ​​function that engages with the limiting edge.

[0017] As a further improvement of this utility model, a screw is provided on the connecting beam.

[0018] As a further improvement of this utility model, the connector is provided with a vertical keel, and the connector is provided with abutting protrusion for abutting the end of the vertical keel.

[0019] As a further improvement of this utility model, the connecting beam is provided with a clearance notch that cooperates with the vertical keel.

[0020] The beneficial effects of this utility model are as follows: By adding a connecting base plate to the lower side between the first and second snap-fit ​​side wing plates on both sides, the originally independently stressed and easily deformed outward (or inward) side wing plates are rigidly connected into an integral frame. This is equivalent to adding a strong transverse support beam below the side wing plates, greatly improving the overall rigidity and bending resistance of the snap-fit ​​area. When the covering keel is snapped into the snap-fit ​​groove and bears loads (such as ceiling weight, installation stress, or vibration during use), the connecting base plate can effectively share and transmit the force acting on the side wing plates, preventing the side wing plates from twisting, expanding outward, or shrinking inward due to uneven force or excessive local stress.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0036] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0037] Example 1, Reference Figure 2 The present utility model embodiment discloses that:

[0038] A snap-on keel, the snap-on keel 1 includes a keel base plate 102 for connecting a hanging rod 2, a first keel side plate 103 and a second keel side plate 104 disposed opposite each other on both sides of the keel base plate 102, a first snap-on side wing plate 105 disposed below the first keel side plate 103, and a second snap-on side wing plate 106 disposed below the second keel side plate 104; the first snap-on side wing plate 105 and the second snap-on side wing plate 106 are provided with a plurality of snap-on grooves 107 along their extension direction.

[0039] A connecting base plate 108 is configured to connect the lower sides of the first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106.

[0040] The connecting base plate 108 has several disconnection sections, and the snap-fit ​​groove 107 corresponds to each of the disconnection sections and extends to the disconnection sections to form a snap-fit ​​channel for connecting the cover keel 3.

[0041] That is, in this embodiment, by adding a connecting base plate 108 between the first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106 (hereinafter referred to as the two snap-fit ​​side wing plates), the two snap-fit ​​side wing plates, which were originally independently stressed and prone to outward (or inward) deformation, are rigidly connected into an integral frame. This is equivalent to adding a strong transverse support beam under the two snap-fit ​​side wing plates, which greatly improves the overall rigidity and bending resistance of the snap-fit ​​area. When the covering keel 3 is snapped into the snap-fit ​​groove 107 and bears the load (such as the weight of the ceiling, installation stress, or vibration during use), the connecting base plate 108 can effectively share and transmit the force acting on the two snap-fit ​​side wing plates, preventing the two snap-fit ​​side wing plates from twisting, expanding outward, or shrinking inward due to uneven force or excessive local stress.

[0042] It is worth mentioning that, in the production process of this embodiment, a square steel pipe can be selected, one end face of which is the keel base plate 102 in this embodiment. Correspondingly, the end face opposite to the keel base plate 102 is the connecting base plate 108. During processing, firstly, holes are made in the keel base plate 102 to form screw holes that can be connected to the hanging rod 2 (screw). Then, it is only necessary to cut along the width direction of the connecting base plate 108 (cutting the connecting base plate 108 and the two side snap-fit ​​side wing plates) to form the snap-fit ​​channel in this embodiment. At this time, the processing is completed. The structure is simple and the processing is convenient.

[0043] Example 2: Reference Figure 3 The present utility model embodiment discloses that:

[0044] A clip-on keel, the clip-on keel 1 includes a first keel side plate 103 and a second keel side plate 104 disposed opposite to each other, and further includes: a first snap-on side wing plate 105, the first snap-on side wing plate 105 being disposed on the lower side of the first keel side plate 103.

[0045] The second snap-fit ​​side wing plate 106 is disposed on the lower side of the second keel side plate 104; the connecting base plate 108 is configured to connect the lower sides of the first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106; wherein, the connecting base plate 108 has a plurality of disconnection intervals, and the first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106 are evenly provided with a plurality of snap-fit ​​grooves 107 along their extension direction, and the snap-fit ​​grooves 107 correspond one-to-one with the disconnection intervals. Extending to the disconnected section, a snap-fit ​​channel is formed connecting the covering keel 3. In this embodiment, by setting a connecting base plate 108 on the lower side between the first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106 (hereinafter referred to as the two snap-fit ​​side wing plates), the two snap-fit ​​side wing plates, which were originally independently stressed and prone to outward (or inward) deformation, are rigidly connected into an integral frame. This is equivalent to adding a strong transverse support beam below the two snap-fit ​​side wing plates, which greatly improves the overall rigidity and bending resistance of the snap-fit ​​area. When the covering keel 3 is snapped into the snap-fit ​​groove 107 and bears a load (such as the weight of the ceiling, installation stress, or vibration during use), the connecting base plate 108 can effectively share and transmit the force acting on the snap-fit ​​side wing plates, preventing the two snap-fit ​​side wing plates from twisting, expanding outward, or shrinking inward due to uneven force or excessive local stress.

[0046] However, in the existing card-type keel 1 (or relative to Embodiment 1), the keel base plate 102 usually has screw holes with a fixed spacing for connecting the hanging rod 2. However, due to the complex construction conditions on the construction site (such as pipeline avoidance, structural errors, etc.), the actual position of the hanging rod 2 often deviates from the screw holes of the keel base plate 102. Based on this, in this embodiment, a connecting groove 110 is formed between the first keel side plate 103 and the second keel side plate 104. The connecting groove 110 has an opening that allows the connector 4 to slide along its extension direction.

[0047] The inner edges of the first keel side plate 103 and the second keel side plate 104 are provided with limiting edges 109 that bend or curl into the connecting groove 110. The limiting edges 109 cooperate with the connector 4 to achieve hanging and locking. Specifically, in this embodiment, the lower end of the connector 4 should be provided with a receiving part and a hanging part provided on the receiving part. The receiving part can slide into the connecting groove 110 from both ends of the clip-type keel 1 in this embodiment, while the hanging part extends upward from the opening direction of the connecting groove 110. The receiving part abuts against the limiting edge 109 to achieve the function of bearing, while the hanging part connects to the wall. The connecting groove 110 allows the connector 4 to slide. That is, the clip-type keel 1 in this embodiment can be adjusted on the construction site to adapt to the construction conditions on the construction site.

[0048] It is worth mentioning that, in the production process of this embodiment, U-shaped channel steel is selected, and the connecting base plate 108 is the keel base plate 102 of the clip-type keel 1 in this embodiment. During processing, it is only necessary to cut along the width direction of the connecting base plate 108 to form the snap-fit ​​channel in this embodiment. Then, the first keel side plate 103 and the second keel side plate 104 are bent or rolled to form the limiting edge 109, and the processing is completed. The structure is simple and the processing is convenient.

[0049] Example 3: Reference Figure 4 The present utility model embodiment discloses that:

[0050] A snap-on keel, the snap-on keel 1 includes a first keel side plate 103 and a second keel side plate 104 disposed opposite to each other, and further includes: a first snap-on side wing plate 105 disposed on the lower side of the first keel side plate 103; a second snap-on side wing plate 106 disposed on the lower side of the second keel side plate 104; and a connecting base plate 108 configured to connect the lower sides of the first snap-on side wing plate 105 and the second snap-on side wing plate 106; wherein the connecting base plate 108 has a plurality of disconnection intervals, and the first snap-on side wing plate 105 and the second snap-on side wing plate 106 have a plurality of snap-on grooves 107 along their extension direction, the snap-on grooves 107 corresponding one-to-one with the disconnection intervals and extending to the disconnection intervals to form snap-on channels for connecting the cover keel 3.

[0051] In this embodiment, by providing a connecting base plate 108 on the lower side between the first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106 (hereinafter referred to as the two snap-fit ​​side wing plates), the two snap-fit ​​side wing plates, which were originally independently stressed and prone to outward (or inward) deformation, are rigidly connected into an integral frame. This is equivalent to adding a strong transverse support beam below the two snap-fit ​​side wing plates, which greatly improves the overall rigidity and bending resistance of the snap-fit ​​area. When the covering keel 3 is snapped into the snap-fit ​​groove 107 and bears a load (such as the weight of the ceiling, installation stress, or vibration during use), the connecting base plate 108 can effectively share and transmit the force acting on the snap-fit ​​side wing plates, preventing the two snap-fit ​​side wing plates from twisting, expanding outward, or shrinking inward due to uneven force or excessive local stress.

[0052] However, in existing card-type keel 1 (or relative to Embodiment 1), the keel base plate 102 usually has pre-set screw holes at fixed intervals for connecting the hanging rod 2. However, due to the complex construction conditions on the building site (such as pipeline avoidance, structural errors, etc.), the actual position of the hanging rod 2 often deviates from the pre-set screw holes of the keel base plate 102. Based on this, in this embodiment, a connecting groove 110 is formed between the first keel side plate 103 and the second keel side plate 104. The connecting groove 110 has an opening that allows the connector 4 to slide along its extension direction. The inner edges of the first keel side plate 103 and the second keel side plate 104 are provided with the connecting groove. The limiting edge 109, which is bent or curled inward, cooperates with the connector 4 to achieve hanging and locking. Specifically, the lower end of the connector 4 should be equipped with a receiving part and a hanging part set on the receiving part. The receiving part can slide into the connecting groove 110 from both ends of the clip-type keel 1 in this embodiment, while the hanging part extends upward from the opening direction of the connecting groove 110. The receiving part abuts against the limiting edge 109 to achieve the function of bearing, while the hanging part connects to the wall. The connecting groove 110 allows the connector 4 to slide. That is, the clip-type keel 1 in this embodiment can be adjusted on the construction site to adapt to the construction conditions on the construction site.

[0053] As a further improvement, a keel base plate 102 is provided between the first keel side plate 103 and the second keel side plate 104, and the first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106 (by welding) are provided on the underside of the keel base plate 102; that is, in this embodiment, the first keel side plate 103, the second keel side plate 104 and the keel base plate 102 form a U-shaped structure (U-shaped channel steel can be directly selected, the first U-shaped channel steel), and the first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106 are respectively located on the underside of the keel base plate 102. The connecting base plate 108 also has a U-shaped structure (U-shaped steel pipe and second U-shaped channel steel can be directly selected). First, the side wall of the first U-shaped channel steel (i.e., the first keel side plate 103 and the second keel side plate 104 in this embodiment) is bent to form a limiting edge 109. Then, it is cut directly along the width direction of the first U-shaped channel steel (on the side close to the connecting base plate 108) to form a snap-fit ​​channel (snap-fit ​​groove 107 and disconnection section). Finally, the second U-shaped channel steel is welded to the bottom of the first U-shaped channel steel. The structure is simple and easy to process.

[0054] Example 4: Reference Figure 5 , Figure 6 , Figure 12 The present utility model embodiment discloses that:

[0055] A snap-on keel, the snap-on keel 1 includes a first keel side plate 103 and a second keel side plate 104 disposed opposite to each other, and further includes: a first snap-on side wing plate 105 disposed on the lower side of the first keel side plate 103; a second snap-on side wing plate 106 disposed on the lower side of the second keel side plate 104; and a connecting base plate 108 configured to connect the lower sides of the first snap-on side wing plate 105 and the second snap-on side wing plate 106; wherein the connecting base plate 108 has a plurality of disconnection intervals, and the first snap-on side wing plate 105 and the second snap-on side wing plate 106 have a plurality of snap-on grooves 107 along their extension direction, the snap-on grooves 107 corresponding one-to-one with the disconnection intervals and extending to the disconnection intervals to form snap-on channels for connecting the cover keel 3.

[0056] In this embodiment, by providing a connecting base plate 108 on the lower side between the first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106 (hereinafter referred to as the two snap-fit ​​side wing plates), the two snap-fit ​​side wing plates, which were originally independently stressed and prone to outward (or inward) deformation, are rigidly connected into an integral frame. This is equivalent to adding a strong transverse support beam below the two snap-fit ​​side wing plates, which greatly improves the overall rigidity and bending resistance of the snap-fit ​​area. When the covering keel 3 is snapped into the snap-fit ​​groove 107 and bears a load (such as the weight of the ceiling, installation stress, or vibration during use), the connecting base plate 108 can effectively share and transmit the force acting on the snap-fit ​​side wing plates, preventing the two snap-fit ​​side wing plates from twisting, expanding outward, or shrinking inward due to uneven force or excessive local stress.

[0057] However, in the existing card-type keel 1 (or in Embodiment 1), the keel base plate 102 usually has pre-set screw holes at fixed intervals for connecting the hanging rod 2. However, due to the complex construction conditions on the building site (such as pipeline avoidance, structural errors, etc.), the actual position of the hanging rod 2 often deviates from the pre-set screw holes of the keel base plate 102. Based on this, in this embodiment, a connecting groove 110 is formed between the first keel side plate 103 and the second keel side plate 104. The connecting groove 110 has an opening that allows the connector 4 to slide along its extension direction, i.e. Figure 6 As shown, in this embodiment, when the connector 4 slides to a suitable position, it is then fixed by fasteners such as bolts.

[0058] refer to Figure 5 In contrast Figure 6 In a further improvement, the inner edges of the first keel side plate 103 and the second keel side plate 104 are provided with limiting edges 109 that bend or curl into the connecting groove 110. The limiting edges 109 cooperate with the connector 4 to achieve hanging and locking.

[0059] Specifically, the lower end of the connector 4 should be equipped with a receiving part and a hanging part set on the receiving part. The receiving part can slide into the connecting groove 110 from both ends of the clip-type keel 1 in this embodiment, while the hanging part extends upward from the opening direction of the connecting groove 110. The receiving part abuts against the limiting edge 109 to achieve the function of bearing, while the hanging part is used to connect to the wall. The connecting groove 110 allows the connector 4 to slide. That is, the clip-type keel 1 in this embodiment can be adjusted on the construction site to adapt to the construction conditions on the construction site.

[0060] However, in Embodiment 4, two U-shaped channel steels need to be designed and connected by welding. Although the two U-shaped channel steels can be processed separately, the production requires more materials and the production cost is high. Therefore, in this embodiment, a keel base plate 102 is provided between the first keel side plate 103 and the second keel side plate 104. The first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106 (integrated) are provided on the underside of the keel base plate 102. The keel base plate 102 includes a first base plate 111 and a second base plate 112. Of course, as... Figure 5 As shown, the first base plate and the second base plate can simultaneously extend inwards towards the first keel side plate 103 and the second keel side plate 104, making the clip-on keel 1 in this embodiment have an overall "T" shape, similarly as... Figure 12 As shown, it can also extend outwards to the first keel side plate 103 and the second keel side plate 104, so that the clip-on keel 1 in this embodiment is in the shape of an inverted "T"; the first base plate is used to integrally form and connect to the first keel side plate 103 and the first snap-on side wing plate 105, and the second base plate is used to integrally form and connect to the second keel side plate 104 and the second snap-on side wing plate 106.

[0061] In this embodiment, the first keel side plate 103, the first base plate, the first snap-fit ​​side wing plate 105, the connecting base plate 108, the second snap-fit ​​side wing plate 106, the second base plate, and the second keel side plate 104 are integrally formed. Specifically, in the production process, each wall surface can be obtained by bending and forming a single integrally formed plate in sequence. After bending and forming, the connecting base plate 108 is cut along its width direction to form a snap-fit ​​channel (snap-fit ​​groove 107 and disconnection section). The structure is simple and easy to process.

[0062] Example 5, Reference Figure 5 , 7 8, 12, The embodiments of this utility model disclose:

[0063] A keel assembly for use in ceiling structures includes a surface keel 3 (also called a secondary keel or cross brace keel), a clip-on keel 1, and a connector 4. The surface keel 3 has a lower end face for connecting to the ceiling panel, and a hook 301 (protrusion) is provided at the upper end of the surface keel 3, which is connected to the clip-on keel 1. The connector 4 is provided on the clip-on keel 1 for connecting to the wall.

[0064] The clip-on keel 1 includes a first keel side plate 103 and a second keel side plate 104 disposed opposite to each other, and further includes: a first snap-fit ​​side wing plate 105 disposed on the lower side of the first keel side plate 103; a second snap-fit ​​side wing plate 106 disposed on the lower side of the second keel side plate 104; and a connecting base plate 108 configured to connect the lower sides of the first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106; wherein the connecting base plate 108 has a plurality of disconnection intervals, and the first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106 have a plurality of snap-fit ​​grooves 107 along their extension direction, the snap-fit ​​grooves 107 corresponding one-to-one with the disconnection intervals and extending to the disconnection intervals to form snap-fit ​​channels for connecting the cover keel 3.

[0065] In this embodiment, by providing a connecting base plate 108 on the lower side between the first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106 (hereinafter referred to as the two snap-fit ​​side wing plates), the two snap-fit ​​side wing plates, which were originally independently stressed and prone to outward (or inward) deformation, are rigidly connected into an integral frame. This is equivalent to adding a strong transverse support beam below the two snap-fit ​​side wing plates, which greatly improves the overall rigidity and bending resistance of the snap-fit ​​area. When the covering keel 3 is snapped into the snap-fit ​​groove 107 and bears a load (such as the weight of the ceiling, installation stress, or vibration during use), the connecting base plate 108 can effectively share and transmit the force acting on the snap-fit ​​side wing plates, preventing the two snap-fit ​​side wing plates from twisting, expanding outward, or shrinking inward due to uneven force or excessive local stress.

[0066] However, due to the complex construction conditions at the building site (such as pipeline avoidance, structural errors, etc.), the actual position of the connector 4 (hanging rod 2) often deviates from the preset screw hole. Based on this, in this embodiment, a connecting groove 110 is formed between the first keel side plate 103 and the second keel side plate 104. The connecting groove 110 has an opening that allows the connector 4 to slide along its extension direction. The inner edges of the first keel side plate 103 and the second keel side plate 104 are provided with limiting edges 109 that bend or curl into the connecting groove 110. The limiting edges 109 cooperate with the connector 4 to achieve hanging and locking. Specifically, in this embodiment, the connector 4 provided on the card-type keel 1 includes two connectors spaced apart. A connecting beam 402 (corresponding to the aforementioned hanging part) is provided between two connecting plates 401. The lower side of the connecting plate 401 is provided with a snap-fit ​​part (corresponding to the aforementioned receiving part) for sliding into the first keel side plate 103 and the second keel side plate 104. The snap-fit ​​part is provided with a snap-fit ​​groove 403 that snaps into the limiting edge 109. The snap-fit ​​part can slide in the connecting groove 110. The connecting beam 402 is provided with a screw hole. The connecting beam 402 is connected to the hanging rod 2 by bolts. The hanging part is connected to the wall. That is, the snap-fit ​​keel 1 in this embodiment can be adjusted on the construction site (sliding the connecting part 4) to adapt to the construction site conditions.

[0067] In this embodiment, a keel base plate 102 is provided between the first keel side plate 103 and the second keel side plate 104. The first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106 (integratedly formed) are disposed on the lower side of the keel base plate 102. The keel base plate 102 includes a first base plate 111 and a second base plate 112. Of course, as... Figure 5 As shown, the first base plate and the second base plate can simultaneously extend inwards towards the inner side of the first keel side plate 103 and the second keel side plate 104, similarly... Figure 12 As shown, it can also extend outwards from the first keel side plate 103 and the second keel side plate 104. The first bottom plate is integrally formed and connected to the first keel side plate 103 and the first snap-fit ​​side wing plate 105, and the second bottom plate is integrally formed and connected to the second keel side plate 104 and the second snap-fit ​​side wing plate 106.

[0068] In this embodiment, the first keel side plate 103, the first base plate, the first snap-fit ​​side wing plate 105, the connecting base plate 108, the second snap-fit ​​side wing plate 106, the second base plate, and the second keel side plate 104 are integrally formed. During the production process, a single integrally formed plate can be bent and formed sequentially to create each end face. After bending and forming, the connecting base plate 108 is cut along its width to form a snap-fit ​​channel (snap-fit ​​groove 107 and disconnection section). The structure is simple and easy to process.

[0069] Example 6, Reference Figure 5 , 9 10, 11, The embodiments of this utility model disclose:

[0070] A keel assembly, which is a structure applied to a ceiling light shade, includes a covering keel 3 (also called a secondary keel or cross brace keel), a clip-on keel 1, and a connector 4. The covering keel 3 has a lower end face for connecting to the light shade panel, and a hook 301 (protrusion) is provided on the upper end of the covering keel 3, which is connected to the clip-on keel 1. The connector 4 is provided on the clip-on keel 1 for connecting to the wall.

[0071] The clip-on keel 1 includes a first keel side plate 103 and a second keel side plate 104 disposed opposite to each other, and further includes: a first snap-fit ​​side wing plate 105 disposed on the lower side of the first keel side plate 103; a second snap-fit ​​side wing plate 106 disposed on the lower side of the second keel side plate 104; and a connecting base plate 108 configured to connect the lower sides of the first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106; wherein the connecting base plate 108 has a plurality of disconnection intervals, and the first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106 have a plurality of snap-fit ​​grooves 107 along their extension direction, the snap-fit ​​grooves 107 corresponding one-to-one with the disconnection intervals and extending to the disconnection intervals to form snap-fit ​​channels for connecting the cover keel 3.

[0072] In this embodiment, by providing a connecting base plate 108 on the lower side between the first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106 (hereinafter referred to as the two snap-fit ​​side wing plates), the two snap-fit ​​side wing plates, which were originally independently stressed and prone to outward (or inward) deformation, are rigidly connected into an integral frame. This is equivalent to adding a strong transverse support beam below the two snap-fit ​​side wing plates, which greatly improves the overall rigidity and bending resistance of the snap-fit ​​area. When the covering keel 3 is snapped into the snap-fit ​​groove 107 and bears a load (such as the weight of the ceiling, installation stress, or vibration during use), the connecting base plate 108 can effectively share and transmit the force acting on the snap-fit ​​side wing plates, preventing the two snap-fit ​​side wing plates from twisting, expanding outward, or shrinking inward due to uneven force or excessive local stress.

[0073] However, due to the complex construction conditions at the building site (such as pipeline avoidance, structural errors, etc.), the actual position of the connector 4 often deviates from the preset connection position. Therefore, in this embodiment, a connecting groove 110 is formed between the first keel side plate 103 and the second keel side plate 104. The connecting groove 110 has an opening that allows the connector 4 to slide along its extension direction. The inner edges of both the first keel side plate 103 and the second keel side plate 104 are provided with limiting edges 109 that bend or curl into the connecting groove 110. The limiting edges 109 cooperate with the connector 4 to achieve hanging and locking. Specifically, in this embodiment… The connector 4, which is disposed on the card-type keel 1, includes two connecting plates 401 spaced apart. A connecting beam 402 is disposed between the two connecting plates 401. The lower side of the connecting plate 401 is provided with a snap-fit ​​part (corresponding to the aforementioned receiving part) for sliding into the first keel side plate 103 and the second keel side plate 104. The snap-fit ​​part is provided with a snap-fit ​​groove 403 that snaps into the limiting edge 109. The snap-fit ​​part can slide into the connecting groove 110. That is, the card-type keel 1 in this embodiment can be adjusted on the construction site (by sliding the connector 4) to adapt to the construction site conditions.

[0074] In this embodiment, the connector 4 is provided with a vertical keel 5, which is used to connect and install the lampshade side panel. The vertical keel 5 includes a vertical plate and vertical sidewalls 501 on both sides of the vertical plate. An installation groove is formed between the vertical sidewalls 501. During installation, the lower end of the vertical keel 5 is directly sleeved on the connector 4, and the inner wall surface of the vertical sidewall 501 is in contact with the connecting plate 401 and fixed by screws. The connector 4 is provided with an abutment boss for abutting the end of the vertical keel 5 to facilitate installation.

[0075] In this embodiment, the vertical sidewall 501 is also provided with a vertical abutment edge 502 that bends into the mounting groove. The connecting beam 402 has an avoidance notch 6 that cooperates with the vertical keel 5. The avoidance notch 6 cooperates with the vertical abutment edge 502, thereby restricting the connector 4 from sliding along the axial (width) direction of the vertical keel 5 and disengaging from the mounting groove.

[0076] In this embodiment, a keel base plate 102 is provided between the first keel side plate 103 and the second keel side plate 104. The first snap-fit ​​side wing plate 105 and the second snap-fit ​​side wing plate 106 (integral-formed) are disposed on the lower side of the keel base plate 102. The keel base plate 102 includes a first base plate and a second base plate. The first base plate is used to integrally form and connect the first keel side plate 103 and the first snap-fit ​​side wing plate 105, and the second base plate is used to integrally form and connect the second keel side plate 104 and the second snap-fit ​​side wing plate 106.

[0077] In this embodiment, the first keel side plate 103, the first base plate, the first snap-fit ​​side wing plate 105, the connecting base plate 108, the second snap-fit ​​side wing plate 106, the second base plate, and the second keel side plate 104 are integrally formed. During the production process, a single integrally formed plate can be bent and formed sequentially to create each end face. After bending and forming, the connecting base plate 108 is cut in the opposite direction along its width to form a snap-fit ​​channel (snap-fit ​​groove 107 and disconnection section). The structure is simple and easy to process.
