Description

Technical Field

[0001] The utility model relates to the technical field of foldable buildings, in particular to a hinged mechanism for a roof plate of a foldable house. Background Art

[0002] The folding house is made of light and thin-walled profiles and has the unique advantages of being detachable, foldable, high-performance, light weight and small footprint. It is widely used in tourism real estate, holiday villas, emergency rescue, car camps, municipal facilities, scenic facilities, commercial streets, etc.

[0003] Folding houses usually use prefabricated panels as the basis for construction, such as A-shaped folding houses. The A-shaped folding house is composed of a house base, a single-side inclined plate, a folding inclined plate and an intermediate fixed plate. The folding inclined plate is formed by connecting two house plates in a hinged manner. Before the A-shaped folding house is built, the house base is hinged to the single-side inclined plate and the folding inclined plate respectively. The hinged connection method not only connects the roofs to each other, but also only needs to be unfolded during construction. After unfolding, the intermediate fixed plate is set between the single-side inclined plate and the folding inclined plate, which has the effect of fixing the entire A-shaped folding house.

[0004] When unfolding the A-shaped folding house, a lifting machine is needed to lift the top of the A-shaped folding house through the lifting rope. At this time, the folding inclined plate is also unfolded together, that is, the process of A1 moving toward A2 in the figure. The lifting process not only needs to maintain the upward feed amount, but also needs to maintain the lateral feed amount. Since the lifting rope itself has poor stability, the position and posture of the lifting machine need to be constantly adjusted during lifting. The overall operation is difficult. The shaking of the lifting rope may cause the folding inclined plate A1 to rotate and fold under the action of gravity, which increases the difficulty of unfolding the A-shaped folding house.

[0005] Therefore, a folding house roof hinge mechanism is proposed to solve the above-mentioned problems. Utility Model Content

[0035] See also Figure 1 The A-shaped folding house 1 comprises a base plate 11, a first inclined roof 12 and a second inclined roof 13 are hingedly connected at both ends of the base plate 11, and a third inclined roof 14 is hingedly connected between the second inclined roof 13 and the first inclined roof 12;

[0036] Based on the above, the A-shaped folding house 1 is an existing structure, wherein the second inclined roof 13 and the third inclined roof 14 correspond to Fig.11 The A1 part, and the first inclined roof 12 corresponds to Fig.11 The A2 part.

[0037] like Figure 4 and Figure 5 As shown, a folding house roof hinge mechanism comprises:

[0038] The hinge seat comprises a first hinge seat 9 and a second hinge seat 10, wherein the first hinge seat 9 and the second hinge seat 10 are respectively arranged on the surfaces of two adjacent roof panels of the A-shaped folding house 1;

[0039] The first hinge seat 9 comprises a first seat body 91, one end of the first seat body 91 is provided with a square hole 92, and the surface of the first seat body 91 is provided with a side hole 93, and the side hole 93 is connected to the square hole 92;

[0040] The second hinge seat 10 comprises a second seat body 101, the first hinge seat 9 is arranged between the second seat bodies 101, a hinge hole 102 and a threaded blind hole 103 are arranged on the surface of the second seat body 101, a mounting housing 3 is arranged at one end of the second seat body 101 by screws, and the first hinge seat 9 and the second hinge seat 10 are respectively arranged at the edges where two adjacent roof panels of the A-shaped folding house 1 contact;

[0041] Based on the above, the hinge hole 102 cooperates with the round rod 2 to achieve a hinged connection with the third inclined roof 14, and the threaded blind hole 103 cooperates with the screw to enable the mounting shell 3 and the mounting cover 4 to be fixed on the surface of the second base body 101. The square hole 92 plays a role in installing the square block 21, and the setting of the side hole 93 enables the screw to be inserted into the interior of the first base body 91.

[0042] like Figure 2 , Figure 3 , Figure 8 and Fig. 9 As shown, the hinged non-return mechanism includes a hinge shaft 2, a mounting shell 3, and a mounting cover 4, wherein:

[0043] The hinge shaft 2 is set inside the first seat body 91 by screws, and the hinge shaft 2 includes a square block 21, and the square block 21 is set inside the square hole 92. Round rods 23 are set at both ends of the square block 21, and the round rods 23 extend to the inside of the hinge hole 102. A prism 24 and a threaded column 25 are sequentially set on the side of the round rod 23 away from the square block 21. A side threaded hole 22 is set on the surface of the square block 21, and the side threaded hole 22 corresponds to the side hole 93;

[0044] An installation housing 3 is installed on one end of the second base body 101 by screws;

[0045] The installation cover 4 includes a cover plate 41, a blocking block 42 is provided on one side of the cover plate 41 close to the installation shell 3, and the cover plate 41 is connected to the installation shell 3 by screws;

[0046] Based on the above, the setting of the articulated shaft 2 plays the role of connecting the first seat body 91 and the second seat body 101, wherein the articulated shaft 2 is fixedly connected to the first seat body 91 under the action of the screw, and the articulated shaft 2 is movably connected to the second seat body 101. The setting of the prism 24 enables the articulated shaft 2 to be relatively fixed when connected to the ratchet 5 to avoid relative movement. The setting of the mounting shell 3 and the mounting cover 4 provides a movable space for the ratchet mechanism, so that the ratchet mechanism can work normally.

[0047] like Figure 8-Figure 10 As shown, the ratchet mechanism includes a ratchet 5, a movable block 7 and a return spring 8, wherein:

[0048] A ratchet 5 is arranged at both ends of the hinge shaft 2 through a fixing nut 6, and the ratchet 5 includes a wheel body 51, and the wheel body 51 is arranged outside the threaded column 25. A positioning prism groove 52 is arranged on one side of the wheel body 51 close to the square block 21, and the prism 24 is arranged inside the positioning prism groove 52;

[0049] A movable block 7 and a return spring 8 are arranged inside the mounting housing 3 and in contact with the ratchet 5. The movable block 7 includes a vertical rod 71, a partition plate 72 is arranged outside the vertical rod 71, an inclined surface 73 is arranged on one side of the vertical rod 71, and a return spring 8 is arranged between the partition plate 72 and the mounting housing 3;

[0050] Based on the above, the ratchet 5 and the hinge shaft 2 are connected and fixed to each other, and the movable block 7 is arranged inside the mounting shell 3. When the first inclined roof 12 and the second inclined roof 13 are unfolded, the second inclined roof 13 drives the hinge shaft 2 and the ratchet 5 to move relative to the first inclined roof 12. In this process, the ratchet 5 squeezes the inclined surface 73, so that the movable block 7 squeezes the reset spring 8 after movement, so that the reset spring 8 is compressed. When the movement stops, the movable block 7 clamps the ratchet 5 under the action of the elastic force, so that the ratchet 5 cannot move in the reverse direction.

[0051] In actual use of this embodiment, when the first inclined roof 12 and the second inclined roof 13 are unfolded, they move from A1 to A2. During this process, the angle between the first inclined roof 12 and the second inclined roof 13 increases, that is, a relative movement occurs between the ratchet 5 and the mounting housing 3. When the ratchet 5 moves, it contacts and squeezes the inclined surface 73. After being squeezed, the movable block 7 moves in a direction away from the ratchet 5, thereby compressing the return spring 8.

[0052] When the first inclined roof 12 and the second inclined roof 13 are deployed, the deployment process stops or even falls back due to pauses and swaying of the lifting rope during actual operation of the lifting machinery. At this time, the movable block 7 clamps the ratchet 5 under the action of the return spring 8, thereby achieving the effect of preliminarily fixing the first inclined roof 12 and the second inclined roof 13, and effectively preventing them from falling back under the action of gravity, resulting in a decrease in the angle between the two.

[0053] The device is provided with a hinged non-return mechanism so that the first inclined roof 12 and the second inclined roof 13 can be fixed when unfolded to avoid falling back due to gravity. When the lifting machinery is adjusted, the posture of the A-shaped folding house is fixed and will not fold again due to gravity, which provides sufficient convenience for the staff of the lifting machinery to achieve the effect of reducing the difficulty of unfolding the A-shaped folding house.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
