Description

Technical Field

[0001] This utility model relates to the field of connection device technology, and specifically to a hinge stabilizing connection device. Background Technology

[0002] Existing hinges (also called folding hinges) are used to fix doors and door frames, or other components, with screws or pop rivets. They also often include some complex irregular hinges. A search revealed existing technology (publication number: CN211229936U), which describes "a novel hinge connection device comprising an aluminum alloy door body, a limiting block, a blind rivet, and an aluminum alloy door frame. A first connecting plate is welded to the inner side of the aluminum alloy door body, and a fixing block is fixedly connected to the lower inner end of the aluminum alloy door body. The limiting block is fixedly connected to the inner surface of the aluminum alloy door body, and an installation gasket is installed on the inner side of the limiting block. A mating hole is formed on the inner surface of the installation gasket. A connecting shaft is installed on the outer side of the aluminum alloy door body, and a hinge is fixedly connected to the outer surface of the connecting shaft. A blind rivet is installed through the outer side of the hinge. An aluminum alloy door frame is installed at the lower end of the aluminum alloy door body. This novel hinge connection device allows users to install it together with the hinge and stainless steel installation gasket. On the same aluminum alloy door body and door frame structure, it greatly increases the load-bearing capacity and service life of the connection parts, thereby preventing them from easily falling off or being damaged."

[0003] While existing hinge installation technologies have improved load-bearing capacity and service life, they still have some shortcomings: When using blind rivets for fixing, existing hinge connection devices may experience positional displacement of the hinge because the hinge does not initially form a bond with the mounting component (door panel, etc.), and the rivet needs to be pressed against the mounting component during the fixing process with a rivet gun. Secondly, conventional blind rivets have a simple structure, achieving fixation within the hole through their own deformation and expansion. However, some wooden or non-metallic door panels have low internal hardness, which may cause the rivet to expand the inner diameter of the hole during the expansion process, thus making it impossible to achieve a stable connection. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a folding stabilizing connection device is provided to solve the problems of instability caused by rivet installation and limitations on installation materials in existing folding connection devices.

[0005] To achieve the above objectives, a folding stabilizing connection device is provided, comprising: a fixing component and a connecting component. The fixing component includes a connecting plate, with gaskets connected to both sides of the connecting plate and pre-fixed ends connected to both ends of the connecting plate. The fixing component is attached to the surface of the folding body. The connecting component is inserted into the interior of the fixing component and includes a core puller, with an expansion tube sleeved on the outer side of the core puller. A locking block is movably connected to the outer side of the expansion tube, and a compression end is connected to the end of the expansion tube.

[0006] Furthermore, the gasket has a first through hole inside, and the first through hole corresponds to the mounting hole of the hinge body.

[0007] Furthermore, the pre-fixed end is designed as an L-shaped structure, and a second through hole is provided at the outer end of the pre-fixed end, and the pre-fixed end is snapped onto the edge of the folding body.

[0008] Furthermore, the expansion tube passes through the first through hole and the mounting hole of the hinge body, and a limiting block is provided on the outside of the first through hole, and the limiting block is installed at the end of the expansion tube away from the compression end.

[0009] Furthermore, the expansion tube has an inner cavity, and the core puller slides through the limiting block and is inserted into the inner cavity, with the inner end of the core puller connected to the compression end.

[0010] Furthermore, the expansion tube has a groove inside, which is located on the outside of the inner cavity, and a spring is provided in the groove.

[0011] Furthermore, a slider is slidably connected inside the groove, with the inner end of the slider connected to a spring and the outer end of the slider connected to a locking block.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. When using, first snap the pre-fixed end of the connecting component onto the edge of the hinge body, and align the first through hole on the gasket with the mounting hole of the hinge body, and also align it with the three pre-drilled holes in the door panel. Then, use screws to pass through the second through hole inside the pre-fixed end to pre-fix the connecting component and the hinge body. Then, insert the connecting component through the fixing component and the hinge body into the drilled hole. At this time, the locking block on the outside of the expansion tube is squeezed and contracted into the groove by the hole wall. Then, use a rivet gun to clamp the core puller, and then squeeze the expansion tube to deform through the compression end during the process of pulling out the core puller, while squeezing the locking block outward into the wooden material of the door panel to complete the installation.

[0014] 2. The connecting plate and pre-fixed end included in the fixing assembly facilitate the initial fixing of the hinge body to the door panel with screws. This avoids the hinge's position shift caused by the rivet gun used when fixing through the connecting assembly, thus ensuring installation stability. The core puller, expansion tube, locking block, slider, and spring included in the connecting assembly allow for insertion and connection with wooden materials by pressing the locking block during riveting, improving installation stability. It can also be used for riveting metal materials, thus not being limited by the installation material and increasing its versatility. Attached Figure Description

[0021] Reference Figures 1 to 5 As shown, this utility model provides a folding stabilizing connection device, including: a fixing component 1 and a connecting component 3. The fixing component 1 includes a connecting plate 11, and gaskets 12 are connected to both sides of the connecting plate 11. Pre-fixed ends 13 are connected to both ends of the connecting plate 11. The fixing component 1 is attached to the surface of the folding body 2. The connecting component 3 is inserted into the inside of the fixing component 1. The connecting component 3 includes a core puller 31, and an expansion tube 33 is sleeved on the outside of the core puller 31. A locking block 35 is movably connected to the outside of the expansion tube 33, and a compression end 39 is connected to the end of the expansion tube 33.

[0022] In this application, the fixing component 1 and the connecting component 3 constitute the main structure of the hinge stabilizing connection device involved in this application.

[0023] Specifically, the fold includes the fold body 2, which is included in this application, as well as other irregularly shaped folds.

[0024] Specifically, the locking block 35 is designed as a thin-walled right-angled plate structure and is made of metal. Before installation, the locking block 35 protrudes from the outer wall of the expansion tube 33, which is also made of metal and has a notch on its outer wall to facilitate the sliding connection of the locking block 35.

[0025] like Figure 1 and Figure 2 In the middle, the gasket 12 has a first through hole 121 inside, and the first through hole 121 corresponds to the mounting hole position of the folding body 2. The pre-fixed end 13 is set as an L-shaped structure, and the pre-fixed end 13 has a second through hole 131 at its outer end, and the pre-fixed end 13 is snapped into the edge of the folding body 2.

[0026] As a preferred implementation, by setting the fixing component 1, it can be fixed to the hinge body 2 on the door panel with screws, thereby facilitating the subsequent operation of the rivet gun without positional displacement.

[0027] like Figure 2 Placed Figure 4 In the process, the expansion tube 33 passes through the first through hole 121 and the mounting hole of the hinge body 2, and a limiting block 32 is provided on the outside of the first through hole 121. The limiting block 32 is installed at the end of the expansion tube 33 away from the compression end 39. An inner cavity 34 is opened inside the expansion tube 33, and the core puller 31 slides through the limiting block 32 and is inserted into the inner cavity 34. The inner end of the core puller 31 is connected to the compression end 39. A sliding groove 37 is opened inside the expansion tube 33 and is located on the outside of the inner cavity 34. A spring 38 is provided in the sliding groove 37. A slider 36 is slidably connected inside the sliding groove 37. The inner end of the slider 36 is connected to the spring 38, and the outer end of the slider 36 is connected to the locking block 35.

[0028] Specifically, the outer end of the locking block 35 contacts the inner wall of the drilled hole in the door panel. When it is squeezed by the compression end 39, the tip of the locking block 35 can be inserted into the material. During the continuous compression process, a stable locking is achieved until the core puller 31 is pulled off by the rivet gun.

[0029] As a preferred embodiment, by setting up a slider 36 and a groove 37, it is possible to retract a portion into the groove 37 when the locking block 35 is inserted into the door panel drill hole, while keeping the outer tip in contact with the inner wall of the material drill hole.

[0030] In use, first, snap the pre-fixed end of the connecting component onto the edge of the hinge body. Simultaneously, align the first through hole on the gasket with the mounting hole of the hinge body and the three pre-drilled holes in the door panel. Then, pre-fix the connecting component and the hinge body by passing a screw through the second through hole inside the pre-fixed end. Next, insert the connecting component through the fixing component and the hinge body into the drilled holes. At this point, the locking block on the outside of the expansion tube is squeezed and retracted into the groove by the hole wall. Then, clamp the core puller with a rivet gun. During the process of pulling out the core puller, the expansion tube is squeezed and deformed by the compression end, while the locking block is squeezed outward and locked into the wooden material of the door panel, thus completing the installation.

[0031] The folding stabilizing connection device of this utility model can effectively solve the problems of instability of existing folding connection devices using rivet installation and the limitation of installation materials. It achieves increased stability of rivet installation based on existing folding stabilizing connection device technology and is applicable to different installation materials.
