Description

Technical Field

[0001] The present invention relates to a folding hinge, a folding roof panel and a folding house. Background Art

[0002] In recent years, due to the gradual increase in transportation, storage and labor costs, folding houses have been widely used in the fields of emergency, military, construction sites, etc. Folding houses mainly rely on the rotational connection of hinges to achieve rapid erection. In actual use, traditional hinges are used for connection, and a sealing strip is set at the rotating part after erection to ensure airtightness. However, for the hinge with a transmission form, the rotation stroke is limited, and the rotation angle of the hinge is limited, which cannot meet the rotation requirements when the roof panels are folded at a large angle, and it is very inconvenient. Summary of the Invention

A first arc-shaped plate and a second arc-shaped plate integrally formed with the partition plate are symmetrically provided on both sides of the partition plate. First limiting blocks and second limiting blocks integrally formed with the partition plate are provided on both sides of the upper end of the partition plate. The first arc-shaped plate, the partition plate and the first limiting block integrally form the first rotating groove after being integrally formed, and the second arc-shaped plate, the partition plate and the second limiting block integrally form the second rotating groove after being integrally formed.

[0006] A first kit with the same radian as the first rotating ear is fixedly provided on the outer wall of the first rotating ear, and a second kit with the same radian as the second rotating ear is fixedly provided on the outer wall of the second rotating ear. Both the first kit and the second kit are plastic parts.

The right end of the second bottom panel is rotatably connected to the lower end of the right roof panel through a hinge member. The left end of the second bottom panel is fixedly connected to the second rotating body.

[0012] The above-mentioned hinge member includes a first hinge body and a second hinge body. The first hinge body is provided with a hinge rotating ear extending along the extending direction of the first hinge body. The second hinge body is provided with a hinge rotating groove extending along the extending direction of the second hinge body. The first hinge body and the second hinge body are rotatably connected through the cooperation of the hinge rotating ear and the hinge rotating groove.

[0013] The third object of the present invention for a patent is to provide a folding house that is convenient to fold, and is convenient for loading, unloading and transportation.

[0014] The technical solution for achieving the object of the present invention for a patent is as follows: The present invention for a patent relates to a folding house, which includes a house body and roof panel groups relatively fixedly arranged on both sides of the house body. Each roof panel group is composed of a plurality of folding roof panels fixedly connected in sequence. The left roof panels and the right roof panels on each folding roof panel are fixedly connected to the right roof panels and the left roof panels on the adjacent folding roof panels on both sides.

[0015] There are communicated outlets on the left roof panel and the right roof panel at the splicing place of two adjacent folding roof panels.

[0016] The present invention for a patent has positive effects: (1) By arranging an intermediate body between the first rotating body and the second rotating body, and providing a first rotating groove and a second rotating groove on the intermediate body for the first rotating ear on the first rotating body and the second rotating ear on the second rotating body to be rotatably connected, the rotational connection between the first rotating ear and the first rotating groove and the rotational connection between the second rotating ear and the second rotating groove effectively solve the problem in the prior art that the rotation angle is limited and cannot meet the folding requirements of the roof panel, which is efficient and practical.

[0017] (2) In the present invention, an intermediate body forms a first rotating groove through a first arc-shaped plate, a partition plate, and a first limiting block, and a second rotating groove is formed by a second arc-shaped plate, a partition plate, and a second limiting block. The first rotating groove and the second rotating groove are arranged opposite to each other, which can ensure that both the first rotating body and the second rotating body can freely control the rotation angle, and can meet the requirements of various folding angles through the cooperation of the rotation angles of the first rotating body and the second rotating body, which is practical and convenient.

[0018] (3) In the present invention, a first kit is arranged on the first rotating ear, and a second kit is arranged on the second rotating ear. By setting the first kit and the second kit, it can effectively avoid the wear of the first rotating ear and the first rotating groove, as well as the second rotating ear and the second rotating groove during rotation. On the other hand, it can also reduce the noise generated during the rotation of the first rotating ear and the first rotating groove, and the second rotating ear and the second rotating groove, which is efficient and practical.

[0019] (4) In the present invention, a first bayonet is arranged on the outer wall of the first rotating ear and a second bayonet is arranged on the outer wall of the second rotating ear. A first clamping block and a second clamping block are arranged on the inner walls of the first kit and the second kit. The first kit and the second kit are fixed on the first rotating ear and the second rotating ear through the connection of the first clamping block and the second clamping block with the first bayonet and the second bayonet. The detachable connection can effectively ensure the connection of the first kit and the second kit, and it is convenient to replace the first kit and the second kit after they are worn, which is very convenient and efficient.

[0020] (5) In the present invention, a first toothed clamping block is arranged on the outer wall of the first rotating ear, a first stop block is arranged on the first arc-shaped plate, a second toothed clamping block is arranged on the outer wall of the second rotating ear, and a second stop block is arranged on the second arc-shaped plate. After the first rotating ear rotates, the first toothed clamping block leans against the first stop block, and after the second rotating ear rotates, the second toothed clamping block leans against the second stop block, which can effectively avoid the rotation back of the first rotating ear and the second rotating ear after rotation, can effectively ensure the rotation stability of the first rotating ear and the second rotating ear after rotation, and can also avoid the serious collision between the first rotating ear and the second rotating ear and the intermediate part due to too fast rotation, which is safe and efficient.

[0021] (6) In the present invention, a first rubber strip and a second rubber strip are arranged on the first rotating body and the second rotating body to press the first arc-shaped plate and the second arc-shaped plate, further ensuring the pressing stability of the first toothed clamping block and the first stop block, and the second toothed clamping block and the second stop block, and further avoiding the rotation back of the first rotating ear and the second rotating ear after rotation, which is efficient and convenient.

[0022] (7) In the present invention, a folding roof plate is provided. The roof plate of the folding house is rotationally connected by a first roof plate and a second roof plate through a hinge for folding houses, and the floor plate of the folding house is rotationally connected by a first floor plate and a second floor plate through a hinge for folding houses, which can ensure that the folding house can be folded to the position occupying the smallest space, thus facilitating loading, unloading, and transportation, which is very convenient.

[0023] (8) The present invention provides a folding house, which is extended and contracted by a set of roof panels fixedly arranged on both sides of the house body. An opening is provided inside the folding roof panel to facilitate people to walk inside, and it is also convenient for transportation after contraction, which is very convenient.
