Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a three-bead spring-loaded hinge. Background Technology

[0002] Three-bead spring-loaded hinges are a common household component, consisting of a female hinge and female hinges. The female hinge has a hinge pin, while the female hinges are divided into a first female hinge, a second female hinge, and a third female hinge. These female hinges are movably connected to the female hinge on the hinge pin via bearings. Both the first and third female hinges have fixing devices, and springs are installed between these fixing devices, with both ends of the springs fixed to locking rings. This design gives the hinge the function of a spring hinge, eliminating the need for additional door catches after installation and effectively preventing the door panel from being blown open by wind.

[0003] A three-bead spring-loaded hinge, patent number CN105696887A, includes a female hinge and a male hinge. The female hinge has a hinge shaft, and the male hinges include a first male hinge, a second male hinge, and a third male hinge. The first, second, and third male hinges are all movably connected to the female hinge via bearings on the hinge shaft. Each of the female and the first and third male hinges has a fixing device, and a spring is installed between the fixing devices. Each fixing device includes a spindle with an annular groove in its center, and a locking ring is fitted onto the annular groove. Both ends of the spring are fixedly connected to the locking ring. This three-bead spring-loaded hinge, with the locking ring fitted onto the annular groove in the center of the fixing device's spindle, and both ends of the spring fixedly connected to the locking ring, gives the hinge the function of a spring hinge. After installing the hinge, there is no need to install various door catches, effectively preventing wind from blowing the door panel.

[0004] The aforementioned device is difficult to maintain during use, and is prone to rusting after prolonged use. This makes it difficult to close doors and windows, reducing the device's lifespan and effectiveness. It also does not provide adequate support for doors and windows, and is susceptible to deformation due to the downward force of gravity during use. Consequently, it is difficult to repair and can only be replaced, increasing operating costs. Utility Model Content

[0024] Please see Figure 1-3This utility model provides a technical solution: a three-bead spring-loaded hinge, comprising: a mounting shaft 1 with two sets of rubber pads 5 on its outer side; a spring-loaded mechanism 2 located on the outer side of the mounting shaft 1, the spring-loaded mechanism 2 including a mounting plate 201 and a connecting plate 202, the two sets of mounting plates 201 being rotatably mounted on the outer side of the mounting shaft 1, and the connecting plate 202 being fixedly mounted between the two sets of mounting plates 201; and a mounting assembly including a rotating mechanism 3 and a supporting mechanism 4, the rotating mechanism 3 being located on the outer side of the mounting shaft 1 and on one side of the spring-loaded mechanism 2, and the supporting mechanism 4 being located on the outer side of the mounting shaft 1 and between the spring-loaded plate 205 and the connecting plate 202.

[0025] Furthermore, the rebound mechanism 2 also includes a fixed plate 203, a rebound piece 204, and a rebound plate 205. A rebound plate 205 is provided on the outer side of the mounting shaft 1. A set of fixed plates 203 is fixedly installed on the outer side of both the rebound plate 205 and the connecting plate 202. The two sets of fixed plates 203 are located between the rebound plate 205 and the connecting plate 202. A slot is provided on the outer side of the fixed plate 203, and a rebound piece 204 is provided in the slot. The rebound plate 205 is fixedly installed on the outer side of the fixed cylinder 301. Two sets of extension plates 6 are fixedly installed on the outer side of the rebound plate 205. Two sets of openings are provided on the outer side of the extension plates 6 and the mounting plate 201. A threaded hole is provided on the outer side of the fixed plate 203, and a screw is threaded into the threaded hole. Two sets of holes are provided on the outer side of the rebound piece 204, and a screw is located in the hole. By rotating the screw, the rusted rebound piece 204 can be replaced after long-term use, which facilitates the maintenance of the device, extends the service life of the device, and improves the performance.

[0026] The rotating mechanism 3 includes a fixed cylinder 301, a mounting cylinder 302, mounting beads 303, a baffle 304, a rubber plate 305, and a partition 306. The fixed cylinder 301 is fixedly mounted on the outer side of the mounting shaft 1. The mounting cylinder 302 is sleeved on the outer side of the fixed cylinder 301. Multiple sets of mounting beads 303 are arranged between the mounting cylinder 302 and the fixed cylinder 301. Two sets of baffles 304 are fixedly mounted on the inner side of the mounting cylinder 302. The outer sides of the mounting beads 303 are in contact with the outer sides of the fixed cylinder 301, the inner sides of the mounting cylinder 302, and the outer sides of the baffles 304. The outer side of the fixed cylinder 301 has an opening... The opening has a rubber plate 305 fixedly installed inside. The outer side of the rubber plate 305 has pinholes. Two sets of partitions 306 are rotatably installed on the outer side of the mounting cylinder 302. The partitions 306 are rotatably installed on the outer side of the mounting plate 201. Lubricating oil can be injected into the fixed cylinder 301 through the pinholes of the rubber plate 305, so that the lubricating oil enters between the fixed cylinder 301 and the mounting cylinder 302, lubricating the rotation of the mounting bead 303, reducing the friction between the mounting cylinder 302 and the fixed cylinder 301, making the device smoother and less labor-intensive during use, and preventing the inside of the device from rusting.

[0027] Furthermore, the support mechanism 4 includes a support block 401, a support plate 402, and a dividing plate 403. Two sets of support blocks 401 are fixedly installed on the outer side of the spring plate 205, and a support plate 402 is fixedly installed on the outer side of one set of mounting plates 201. The support plate 402 is located between the spring plate 205 and the mounting plate 201. A dividing plate 403 is fixedly installed between the two sets of mounting plates 201. A rubber pad 5 is fixedly installed on the outer side of the support block 401. By rotating the spring plate 205, the support block 401 can be positioned between the two sets of mounting plates 201, so that the outer side of the support block 401 is in contact with the outer side of the mounting plate 201, the dividing plate 403, and the support plate 402. The outer side of the support plate 402 supports the support block 401, thereby supporting the doors and windows installed on the outer side of the spring plate 205, resisting the weight of the doors and windows, and preventing the device from deforming due to the weight of the doors and windows.

[0028] Working principle: The mounting plate 201 is attached to the door frame, and fixing screws are drilled into the opening to fix the mounting plate 201. This ensures that the outer sides of the spring plate 205 and the extension plate 6 are attached to the door. Fixing screws are drilled into the opening to fix the spring plate 205 and the extension plate 6 to the door. Lubricating oil is injected into the mounting cylinder 302 through the pinhole of the rubber plate 305 to lubricate the mounting bead 303. Rotating the door causes the spring plate 205 to rotate, which in turn causes the mounting cylinder 302 to rotate, pulling the spring plate 20. 4. Deformation: The spring sheet 204 rebounds against the spring plate 205, causing the support block 401 to rebound and fit against the outer side of the mounting plate 201, the dividing plate 403, and the support plate 402. This allows the support plate 402 to support the support block 401. The dividing plate 403 prevents the door from swaying left and right. After prolonged use, the screws can be turned to pull the spring sheet 204 out of the slot and replace it. The support mechanism 4 can buffer the door when the support block 401 rebounds, preventing damage to the door frame.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
