Description

Technical Field

[0001] This utility model relates to the field of corner code technology, specifically a lightweight composite material frame corner code. Background Technology

[0002] Lightweight composite frame corner brackets are lightweight, high-strength components used to connect and fix frame structures. They are typically made of composite materials (such as carbon fiber reinforced plastic, glass fiber reinforced plastic, or honeycomb sandwich structures) and are widely used in aerospace, automotive manufacturing, building curtain walls, photovoltaic industry, electronic equipment and other fields.

[0003] Publication number CN221597805U discloses a composite material frame corner bracket for photovoltaic products. Through a double-fastening structure, it is simple to install, requires no riveting, and boasts high connection strength. Two rows of interference-fit serrated structures ensure a tight fit with the inner wall of the frame after insertion. The height and number of interference fits have undergone rigorous calculation and experimentation; insufficient interference results in inadequate fastening, while excessive interference can easily cause frame cracking. The positioning pins employ a beveled structure for easy insertion into the frame's inner cavity. However, this patent still has the following problems in practical use:

[0004] The position of the mounting holes is fixed and cannot be adjusted. Since composite material frames come in different specifications, when it is necessary to install other specifications of composite material frames, it is necessary to find the appropriate size of the corner bracket in the toolbar. This makes it inconvenient to install the corner bracket and thus affects the work.

[0005] A lightweight composite material frame corner bracket is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a lightweight composite material frame corner bracket to solve the problem mentioned in the background art that the position of the mounting hole is fixed and cannot be adjusted. Since composite material frames come in different specifications, when it is necessary to install other specifications of composite material frames, it is necessary to find the appropriate size corner bracket in the toolbar, which makes it inconvenient to install the corner bracket and thus affects the work.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lightweight composite material frame corner bracket, comprising an upper corner bracket body and a lower corner bracket body installed at the bottom of the upper corner bracket body;

[0008] Also includes:

[0009] The upper corner code body and the lower corner code body are both provided with adjustment components. The adjustment components include a slot, and the slot is opened inside the upper corner code body. A sliding plate is slidably connected inside the slot, and the sliding plate is provided with mounting holes inside.

[0010] Among them, the upper corner code body has symmetrically opened limit grooves when pulled out, and the limit grooves are slidably connected to limit blocks, and the limit blocks are fixedly connected to the slide plate.

[0011] The limiting block has symmetrically opened sliding grooves inside, and a positioning plate is slidably connected inside the sliding groove. The positioning plate is fixedly connected to the upper corner code body.

[0012] Preferably, the limiting block has a retaining strip on its outside, and a control block is fixedly connected to one side of the retaining strip, and a first retaining groove is formed inside the limiting block.

[0013] Preferably, the positioning plate has a second slot inside, and the first slot communicates with the second slot.

[0014] Preferably, the card strips are adapted to the first card slot and the second card slot respectively.

[0015] Preferably, a locking component is provided on one side of the card strip. The locking component includes a card block, which is fixedly connected to the card strip. Furthermore, movable grooves are provided inside both the upper corner code body and the positioning plate.

[0016] Preferably, the movable slots coincide with the corresponding first and second slots.

[0017] Preferably, the positioning plate has a limiting groove inside, and the locking block can be rotatably locked inside the limiting groove, and a friction surface is installed on the outside of the limiting groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are: this lightweight composite material frame corner bracket can adjust the position of the mounting holes according to the specifications of the frame, thereby adapting to composite material frames of different specifications, while also ensuring the stability of the mounting holes after adjustment. The specific details are as follows:

[0019] 1. When it is necessary to adjust the mounting holes according to the specifications of the composite material frame, the slide plate can be pulled upwards. The slide plate will then move upwards, and the position with the mounting holes will also move upwards. The rise of the slide plate will cause the position of the limiting block to rise. After the slide plate is adjusted to the appropriate position, the locking strip is inserted into the first locking slot. The locking strip will then pass through the first locking slot and enter the second locking slot, thereby limiting the position of the first locking slot, that is, limiting the position of the adjusted mounting holes. This allows the position of the mounting holes to be adjusted, thus adapting to composite material frames of different specifications.

[0020] 2. When the card strip is inserted into the first and second card slots, the card block will also be inserted into the limiting groove. The limiting groove can be circular and can ensure that the card block can rotate inside. Then, the control block can be rotated to make the card strip rotate, which in turn causes the card strip to drive the card block to rotate. Then the card block will rotate 90 degrees. At this time, the card block and the positioning plate form a block, making it difficult for the card strip to fall out. With the friction surface, the friction between the card block and the positioning plate can be increased, which can greatly ensure the stability after the mounting hole is adjusted, thereby further ensuring the stability after the mounting hole is adjusted.

[0027] 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.

[0028] Please see Figure 1 - Figure 5 The present invention provides the following technical solution:

[0029] A lightweight composite material frame corner bracket includes an upper corner bracket body 1 and a lower corner bracket body 2 installed at the bottom of the upper corner bracket body 1. Both the upper corner bracket body 1 and the lower corner bracket body 2 are internally provided with an adjustment component 3. The adjustment component 3 includes a slot 301, which is formed inside the upper corner bracket body 1. A sliding plate 302 is slidably connected inside the slot 301, and the sliding plate 302 has mounting holes 303 inside. The upper corner bracket body 1 has symmetrically formed limiting grooves 304 when pulled out, and limiting blocks 305 are slidably connected inside the limiting grooves 304. The limiting blocks 305 are fixedly connected to the sliding plate 302. The limiting blocks 305 have symmetrically formed sliding grooves 306 inside. Figure 1 , Figure 3 - Figure 4 As shown, the upper corner bracket body 1 and the lower corner bracket body 2 are respectively placed against the two composite material frames, and then the corner brackets can be installed through the mounting holes 303, that is, the composite material frames are connected and installed.

[0030] Secondly, when it is necessary to adjust the mounting hole 303 according to the specifications of the composite material frame, the slide plate 302 can be pulled upward. Then the slide plate 302 will move upward and the position of the mounting hole 303 will move upward. Then the rise of the slide plate 302 will drive the position of the limit block 305 to rise. Then, when the slide plate 302 is adjusted to the appropriate position, the positioning plate 307 is slidably connected inside the slide groove 306, and the positioning plate 307 is fixedly connected to the upper corner code body 1.

[0031] The limiting block 305 has a retaining strip 308 on its exterior, and a control block 309 is fixedly connected to one side of the retaining strip 308. The limiting block 305 has a first retaining groove 310 inside, and the positioning plate 307 has a second retaining groove 311 inside. Figure 2 - Figure 3 As shown, the clip 308 is inserted into the first slot 310, and then the clip 308 passes through the first slot 310 and enters the second slot 311. Furthermore, multiple first slots 310 and second slots 311 can be provided to accommodate the sliding plate 302 moving to different positions. This limits the position of the first slot 310, i.e., limits the position of the adjusted mounting hole 303, thereby allowing the position of the mounting hole 303 to be adjusted to accommodate composite material frames of different specifications. The first slot 310 and the second slot 311 are connected, and the clip 308 is adapted to each other in the first slot 310 and the second slot 311 respectively.

[0032] A locking component 4 is provided on one side of the card strip 308. The locking component 4 includes a card block 401, which is fixedly connected to the card strip 308. Both the upper corner code body 1 and the positioning plate 307 have movable grooves 402 inside. The movable grooves 402 overlap with the corresponding first card slot 310 and second card slot 311, respectively. The positioning plate 307 has a limiting groove 403 inside. Figure 5 As shown, when the card strip 308 is inserted into the first card slot 310 and the second card slot 311, the card block 401 will also be inserted into the limiting slot 403. Furthermore, the number of limiting slots 403 is the same as the number of second card slots 311. The shape of the limiting slot 403 can be circular, and it can ensure that the card block 401 can rotate inside. Then, the control block 309 can be rotated to make the card strip 308 rotate.

[0033] This causes the locking strip 308 to drive the locking block 401 to rotate, and then the locking block 401 will rotate 90 degrees. At this time, the locking block 401 and the positioning plate 307 form a block, making it difficult for the locking strip 308 to fall out. With the cooperation of the friction surface 404, the friction between the locking block 401 and the positioning plate 307 can be increased, which can greatly ensure the stability of the mounting hole 303 after adjustment. This further ensures the stability of the mounting hole 303 after adjustment. The locking block 401 can be rotatably locked inside the limiting groove 403, and the friction surface 404 is installed on the outside of the limiting groove 403.

[0034] Working principle: Before using this lightweight composite material frame corner bracket, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 5 As shown, firstly, the upper corner bracket body 1 and the lower corner bracket body 2 are respectively placed against the two composite material frames. Then, the corner brackets can be installed through the mounting holes 303, that is, the composite material frames are connected and installed. Secondly, when it is necessary to adjust the mounting holes 303 according to the specifications of the composite material frames, the sliding plate 302 can be pulled upward. Then, the sliding plate 302 will move upward and the position of the mounting holes 303 will move upward. Then, the rise of the sliding plate 302 will drive the position of the limiting block 305 to rise. Then, after the sliding plate 302 is adjusted to the appropriate position, the locking strip 308 is inserted into the inside of the first locking slot 310. Then, the locking strip 308 will pass through the first locking slot 310 and enter the inside of the second locking slot 311, thereby limiting the position of the first locking slot 310, that is, limiting the position of the adjusted mounting holes 303. Thus, the position of the mounting holes 303 can be adjusted to adapt to composite material frames of different specifications.

[0035] When the locking strip 308 is inserted into the first locking slot 310 and the second locking slot 311, the locking block 401 will also be inserted into the limiting slot 403. The limiting slot 403 can be circular in shape and can ensure that the locking block 401 can rotate inside. Then the control block 309 can be rotated to make the locking strip 308 rotate, which in turn causes the locking strip 308 to drive the locking block 401 to rotate. Then the locking block 401 will rotate 90 degrees. At this time, the locking block 401 and the positioning plate 307 form a block, making it difficult for the locking strip 308 to fall out. With the cooperation of the friction surface 404, the friction between the locking block 401 and the positioning plate 307 can be increased, which can greatly ensure the stability of the mounting hole 303 after adjustment, thereby further ensuring the stability of the mounting hole 303 after adjustment.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
