Description

Technical Field

[0001] This utility model relates to the field of metal bracket technology, specifically a foldable metal bracket. Background Technology

[0002] Metal supports are structural frames made of metal that provide structural support. They are rod-type support structures made of metal materials and are widely used in industry, medicine, construction, and other fields. They offer advantages such as providing long-term stability and adaptability to complex environments. For example: Chinese Patent Publication No. CN220192568U discloses a foldable metal bracket with multi-level height adjustment, including a base and a metal bracket. The base has sliding grooves on both sides of its top, with sliding blocks slidably installed within each groove. One end of each sliding block extends into the groove, and the other end extends out of the groove. A first rotating shaft is rotatably mounted on the end of the sliding block extending out of the groove. A connecting rod is fixedly mounted on the first rotating shaft, and a second rotating shaft is rotatably mounted on the other end of the connecting rod. Short rods are fixedly mounted on both sides of the bottom of the metal bracket, with the other ends of the short rods fixedly connected to the second rotating shaft. A sliding hole is formed on one inner wall of the sliding groove, and a sliding rod is slidably installed within the sliding hole. This utility model features a sliding rod within the base, with multiple fixed grooves on the sliding rod, allowing for easy and quick height adjustment according to the desired height.

[0003] Based on existing solutions and actual production and processing, current metal brackets still have some problems, such as: 1. When folding the metal bracket, the sliding rod and connecting rod are used to fold the metal bracket. Since the sliding rod is located on both sides of the base, the sliding rod on both sides needs to be pushed at once when folding, which makes the folding process of the metal bracket longer and more complicated. 2. Since the metal bracket is fixedly installed on the short rod, the disassembly and replacement of the folding structure will be ineffective. Therefore, this utility model provides a folding metal bracket to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a foldable metal bracket to solve the problems mentioned in the background art, which involve folding the metal bracket by means of sliding rods and connecting rods. Since the sliding rods are located on both sides of the base, the sliding rods on both sides need to be pushed at once when folding, which results in a long and complicated folding process for the metal bracket. Also, since the metal bracket is fixedly installed on the short rod, the disassembly and replacement of the folding structure is not effective.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a foldable metal bracket, including a fixed base plate, on which an mounting plate is movably mounted; Also includes: The first movable plate is installed on the upper outer side of the mounting plate, and the upper end of the first movable plate is connected to a lifting structure. The lifting structure includes a movable plate, a mounting rod, and a second movable plate. The movable plate is installed on the upper side of the first movable plate, the middle part of the movable plate is movably connected to the mounting rod, and the upper side of the movable plate is connected to the second movable plate. A connecting plate is installed on the upper side of the lifting structure, and a metal bracket plate is provided on the upper side of the connecting plate. A fixed positioning rod is installed on the lower outer side of the metal bracket plate, and a limiting structure is connected to the lower middle side of the metal bracket plate. The limiting structure includes a movable block and a mounting limiting rod. The movable block is installed on the lower middle side of the metal bracket plate, and the lower side of the movable block is connected to the mounting limiting rod.

[0006] Preferably, an installation block is also fixedly installed on the upper middle side of the fixed base plate, and the installation block and the installation plate are connected by a snap-fit ​​connection.

[0007] Preferably, a connecting spring is fixedly provided on the upper middle side of the mounting plate, and a movable limiting rod is connected through the middle of the connecting spring, and a fixing rod is movably installed on the lower inner side of the mounting plate.

[0008] Preferably, the mounting rod and the movable plate are connected by a thread, and the movable plate and the second movable plate are connected by a rotatable connection.

[0009] Preferably, the movable block and the metal support plate are rotatably connected, the vertical cross-section of the movable block is an "L" shape, and the movable block and the mounting limit rod are threadedly connected.

[0010] Preferably, the fixing rod and the mounting plate are connected by a thread and the fixing rod also serves to limit the position of the mounting plate.

[0011] Preferably, the movable limiting rod and the mounting plate are telescopically sliding connected, and the lower rear end of the movable limiting rod is inclined.

[0012] Preferably, the connecting plate and the fixed positioning rod are connected by a snap-fit ​​connection, and the vertical cross-section of the fixed positioning rod is a triangular structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the foldable metal bracket is provided with a lifting structure, which can lift the metal bracket, thereby folding the metal bracket; and a limit structure is provided, which can install the lifting structure. 1. By installing the mounting plate on the upper side of the fixed base plate, the mounting plate moves backward on the outer side of the mounting block, causing the mounting block to push the moving limit rod upward. This causes the moving limit rod to extend the connecting spring, allowing the mounting plate to engage with the outer side of the mounting block. The connecting spring then moves the moving limit rod downward to the upper side of the mounting block for engagement. Rotating the fixing rod causes it to be threaded on the inner side of the lower end of the mounting plate, allowing the fixing rod to move outward and then be threaded on the inner side of the mounting block. This facilitates the installation of the mounting plate and the fixed base plate. 2. By moving the connecting plate to the lower side of the metal bracket plate, the connecting plate is engaged with the lower outer side of the fixed positioning rod. Then, the movable block is rotated so that it rotates outward from the middle side of the lower end of the metal bracket plate, thereby engaging with the lower inner side of the connecting plate. The installation limit rod is rotated so that it is threadedly connected to the lower outer side of the movable block, thereby moving the installation limit rod upward and threading it with the lower side of the connecting plate, which facilitates the installation between the connecting plate and the metal bracket plate. 3. By rotating the mounting rod, the movable plate that is threadedly connected to the mounting rod moves outward, thereby causing the first movable plate that is rotatably connected to the movable plate to rotate outside the mounting plate. This, in turn, causes the second movable plate that is rotatably connected to the movable plate to rotate at the lower end of the connecting plate, causing the connecting plate to move downward. This, in turn, causes the connecting plate to move the metal bracket plate downward, facilitating the folding of the metal bracket plate. Attached Figure Description

[0016] 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.

[0017] Please see Figure 1-6 This utility model provides a technical solution: a foldable metal bracket, comprising a fixed base plate 1, a mounting plate 2, a first movable plate 3, a moving plate 4, a mounting rod 5, a second movable plate 6, a metal bracket plate 7, a movable block 8, a mounting block 9, a fixed rod 10, a connecting spring 11, a moving limit rod 12, a connecting plate 13, a fixed positioning rod 14, and a mounting limit rod 15. In operation, it is specifically designed as follows... Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a mounting block 9 is fixedly installed on the upper middle side of a fixed base plate 1. A mounting plate 2 is movably installed on the upper outer side of the mounting block 9. A connecting spring 11 is fixedly installed on the upper middle side of the mounting plate 2. A movable limiting rod 12 is connected through the middle of the connecting spring 11. A fixing rod 10 is movably installed on the lower inner side of the mounting plate 2. When the mounting plate 2 is manually placed on the upper side of the fixed base plate 1, the mounting plate 2 slides backward on the outer side of the mounting block 9. This causes the mounting block 9 to push the movable limiting rod 12 upward, which in turn causes the movable limiting rod 12 to drive the connecting spring 11 to extend, so that the mounting plate 2 engages with the outer side of the mounting block 9, thereby enabling the mounting plate 2 to be installed. The pushing force of block 9 on the moving limit rod 12 disappears, and then under the elastic action of the connecting spring 11, the connecting spring 11 drives the moving limit rod 12 to move downward in the middle of the mounting plate 2, so that the moving limit rod 12 is engaged on the upper side of the mounting block 9. Then tighten the fixing rod 10, so that under the tightening action, the fixing rod 10 is threaded on the lower inner side of the mounting plate 2. Thus, under the thread action between the fixing rod 10 and the mounting plate 2, the fixing rod 10 moves inward, and under the inward movement of the fixing rod 10, the fixing rod 10 is threaded on the inner side of the mounting block 9, which facilitates the mounting plate 2 to be installed on the upper side of the fixed base plate 1. Specific examples Figure 1 , Figure 3 and Figure 4 As shown, a fixed positioning rod 14 is fixedly installed on the outer side of the lower end of the metal bracket plate 7. A connecting plate 13 is movably installed on the lower end of the fixed positioning rod 14. A movable block 8 is movably installed on the middle side of the lower end of the metal bracket plate 7. A mounting limit rod 15 is movably connected to the inner side of the lower end of the movable block 8. The connecting plate 13 is moved to the lower side of the metal bracket plate 7, so that the connecting plate 13 is engaged with the outer side of the lower end of the fixed positioning rod 14. Then, the movable block 8 is manually rotated outward, so that the movable block 8 rotates on the middle side of the lower end of the metal bracket plate 7 under the action of rotation. Under the rotation of the movable block 8, the movable block 8 is engaged and installed on the lower outer side of the connecting plate 13. Then, the installation limit rod 15 is tightened, so that the installation limit rod 15 is threadedly connected to the lower inner side of the movable block 8 under the tightening action. Thus, under the thread action between the installation limit rod 15 and the movable block 8, the installation limit rod 15 moves upward, and then the installation limit rod 15 is threadedly connected to the lower outer side of the connecting plate 13, which facilitates the installation between the connecting plate 13 and the metal bracket plate 7, and thus facilitates the assembly of the metal bracket. Specific examples Figure 1 , Figure 4 and Figure 6 As shown, a first movable plate 3 is movably installed on the outer side of the upper end of the mounting plate 2; a movable plate 4 is movably connected to the outer side of the upper end of the first movable plate 3; a mounting rod 5 is movably installed in the middle of the movable plate 4; a second movable plate 6 is movably connected to the outer side of the upper end of the movable plate 4; and a connecting plate 13 is movably connected to the inner side of the upper end of the second movable plate 6. Manually rotating the mounting rod 5 installed in the middle of the movable plate 4 causes the mounting rod 5 to be threaded in the middle of the movable plate 4. Under the threaded action between the mounting rod 5 and the movable plate 4, the movable plate 4 slides outward. Furthermore, under the inward movement of the movable plate 4, the first movable plate 3... The lower side of the movable plate 4 rotates, causing the first movable plate 3, which is rotatably connected to the movable plate 4, to rotate outside the mounting plate 2. As the movable plate 4 moves inward, the second movable plate 6 rotates above the movable plate 4. Furthermore, the rotation between the second movable plate 6 and the movable plate 4 causes the second movable plate 6 to rotate outside the lower end of the connecting plate 13, causing the connecting plate 13 to move downward. This causes the connecting plate 13 to drive the metal support plate 7 to move downward, thereby reducing the distance between the metal support plate 7 and the fixed base plate 1, making it easier to fold the metal support plate 7.
