Description

Technical Field

[0001] This utility model relates to the field of composite honeycomb panel technology, specifically a composite honeycomb panel that is easy to clamp and fix. Background Technology

[0002] Composite honeycomb panels are a type of board made with honeycomb-shaped boards as the middle layer. They are stronger than ordinary boards and are not easily bent. They are generally used in the aerospace industry. With the development of composite honeycomb panels, their performance has also been improved, and they are also suitable for building construction, decoration and other fields.

[0003] A search revealed a patent document CN201822033671.4 which discloses "a composite honeycomb panel with male and female slots", including a face panel, a back panel, and a honeycomb clamp between the face panel and the back panel. The honeycomb clamp is provided with male and female slots on both sides, which makes it easy to clean and prevents dirt from accumulating. It is also quick and easy to install, has a solid structure, high strength, and stable physical properties.

[0004] This patent uses a slot-insertion method to splice two composite honeycomb panels, which cannot achieve a fixed connection at the splice point. As a result, it is prone to falling off after long-term use, and the large gap at the connection point makes its assembly stability poor. To address this, we propose a composite honeycomb panel that is easy to clamp and fix, in order to solve the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this invention is to provide a composite honeycomb panel that is easy to clamp and fix, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a composite honeycomb panel that is easy to clamp and fix, comprising a face panel, a back panel, a honeycomb clamp, and an edge sealing connecting frame. The honeycomb clamp is installed between the face panel and the back panel. The face panel, the back panel, and the honeycomb clamp are all installed on the side wall of the edge sealing connecting frame. A main connecting block is fixedly installed on the right side of the edge sealing connecting frame, and a main slot adapted to the main connecting block is opened on the left side of the edge sealing connecting frame.

[0007] Furthermore, the main connecting plug has connecting grooves at both the top and bottom, and secondary connecting plugs are fixedly connected to the inner wall of the connecting grooves by a number of elastic elements. The sealing connecting frame has secondary slots that are adapted to the secondary connecting plugs at both the top and bottom of the inner wall of the main slot.

[0008] Furthermore, the side of the secondary connecting block away from the edge sealing connecting frame is an inclined surface, and the left side of the edge sealing connecting frame is symmetrically provided with oblique grooves that communicate with the main slot. The oblique grooves and the corresponding secondary slots are interconnected through connecting channels.

[0009] Furthermore, the top and bottom of the edge sealing connector are provided with unlocking holes that communicate with each other at the positions corresponding to the secondary slots.

[0010] Furthermore, the sealing connection frame has side reinforcement holes on both the front and rear sides corresponding to the sub-slots. The side reinforcement holes are equipped with reinforcement bolts, one end of which passes through the side reinforcement hole and extends into the sub-connecting block for insertion.

[0011] Furthermore, the surface of the reinforcing bolt is provided with external threads, and a through screw hole adapted to it is provided between the side reinforcing hole and the sub-slot and at the position corresponding to the reinforcing bolt.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention, when splicing two composite honeycomb panels, establishes primary positioning through the insertion and engagement of the main connecting block and the main slot. Simultaneously, a secondary connecting block driven by an elastic element engages with the secondary slot, forming a secondary elastic locking structure. When subjected to lateral tension, the secondary connecting block and the inner wall of the secondary slot generate a self-locking effect, effectively resisting pull-out force. Furthermore, the reinforcing bolts in the side reinforcing holes form an insertion connection with the secondary connecting block, further enhancing the installation stability of the secondary connecting block. When it is necessary to remove the two connected panels, the reinforcing bolts can be removed first, and the locking mechanism can be unlocked by inserting a tool through the unlocking hole and pressing down on the secondary connecting block, allowing them to be pulled out. This composite honeycomb panel, which facilitates clamping and fixing, has a reasonable structural design and is easy to use. Employing both elastic clamping and bolt fixing methods, it enables rapid clamping and fixing of two composite honeycomb panels while ensuring the stability of the connection and preventing them from detaching. Simultaneously, the connection is gap-free, preventing dust infiltration. The contact surfaces of the two panels are closely fitted, further improving assembly stability. Attached Figure Description

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

[0020] Please see Figure 1-4 A composite honeycomb panel that is easy to clamp and fix includes a face panel 1, a back panel 2, a honeycomb clamp 3, and an edge sealing connecting frame 4. The honeycomb clamp 3 is installed between the face panel 1 and the back panel 2. The face panel 1, the back panel 2, and the honeycomb clamp 3 can be bonded together by adhesive or hot pressing to form a composite honeycomb panel. The face panel 1 and the back panel 2 are made of aluminum alloy plates, and the honeycomb clamp 3 is an aluminum honeycomb core. The face panel 1, the back panel 2, and the honeycomb clamp 3 are all installed on the side wall of the edge sealing connecting frame 4. After the composite honeycomb panel is formed, the edge sealing connecting frame 4 is bonded to its outer surface by adhesive. A main connecting plug 5 is fixedly installed on the right side of the edge sealing connecting frame 4, and a main slot 6 adapted to the main connecting plug 5 is opened on the left side of the edge sealing connecting frame 4. The primary positioning of the two panels is formed by the insertion and cooperation of the main connecting plug 5 and the main slot 6.

[0021] The main connecting plug 5 has connecting grooves 7 at both the top and bottom. The inner wall of the connecting groove 7 is fixedly connected to the auxiliary connecting plug 9 by several elastic elements 8. The elastic elements 8 can be made of 304 stainless steel springs or polyurethane elastomers, which have a long service life. The edge sealing connecting frame 4 has auxiliary slots 10 at the top and bottom of the inner wall of the main slot 6 that are adapted to the auxiliary connecting plug 9. The auxiliary connecting plug 9 driven by the elastic elements 8 is inserted into the auxiliary slot 10 to form a two-stage elastic locking structure. When subjected to lateral tension, the auxiliary connecting plug 9 and the inner wall of the auxiliary slot 10 generate a self-locking effect.

[0022] The side of the secondary connecting block 9 away from the edge sealing connecting frame 4 is an inclined surface. The left side of the edge sealing connecting frame 4 is symmetrically provided with a beveled groove 11 corresponding to the position of the main slot 6, which is connected to it. The contact angle α between the inclined surface and the secondary slot 10 is preferably 45°. The beveled groove 11 and the corresponding secondary slot 10 are connected to each other through the connecting channel 12. By setting the beveled groove 11 and the connecting channel 12, when the main connecting block 5 is pushed into the main slot 6, it is convenient to squeeze the secondary connecting block 9 to move towards the connecting groove 7. When the secondary connecting block 9 moves to the deepest point, the elastic member 8 pushes it back to its original position and inserts it into the secondary slot 10 to achieve secondary locking.

[0023] The top and bottom of the edge sealing connector 4 are provided with unlocking holes 13 that communicate with the sub-slot 10. The tool is inserted through the unlocking hole 13 to press down the sub-connecting block 9 to unlock it.

[0024] Side reinforcement holes 14 are provided on both the front and rear sides of the edge sealing connecting bracket 4, corresponding to the positions of the secondary slots 10. Reinforcing bolts 15 are provided inside the side reinforcement holes 14. One end of the reinforcing bolts 15 passes through the side reinforcement holes 14 and extends into the secondary connecting block 9 to be inserted therein.

[0025] The surface of the reinforcing bolt 15 is provided with external threads. The side reinforcing hole 14 and the sub-slot 10 are provided with through screw holes that are compatible with it. After the sub-connecting plug 9 is inserted into the sub-slot 10, the reinforcing bolt 15 in the side reinforcing hole 14 forms a plug-in connection with the sub-connecting plug 9, and locking it further improves the installation stability of the sub-connecting plug 9.

[0026] This composite honeycomb panel, which is easy to clamp and fix, has a reasonable structural design and is convenient to use. It adopts a dual method of elastic clamping and bolt fixing, which can realize the quick clamping and fixing of two composite honeycomb panels and ensure the stability of the connection. It is not easy for them to fall off each other. At the same time, there are no gaps at the connection, which can prevent dust from seeping in. The contact surfaces of the two panels fit together, which can further improve the assembly stability.

[0027] Working principle: When splicing two composite honeycomb panels, the primary positioning is formed by the insertion and cooperation of the main connecting plug 5 and the main slot 6. At the same time, the secondary connecting plug 9 driven by the elastic element 8 is inserted into the secondary slot 10 to form a secondary elastic locking structure. When subjected to lateral tension, the secondary connecting plug 9 and the inner wall of the secondary slot 10 generate a self-locking effect, effectively resisting the pull-out force. Then, the secondary connecting plug 9 is connected by the reinforcing bolt 15 in the side reinforcing hole 14, which further improves the installation stability of the secondary connecting plug 9. When it is necessary to remove the two connected panels, the reinforcing bolt 15 can be removed first, and the secondary connecting plug 9 can be released by inserting a tool through the unlocking hole 13 and pressing it down. Then, they can be pulled out.
