Description

Technical Field

[0001] This utility model relates to the field of gate and fence technology, and specifically to a gate and fence. Background Technology

[0002] A gate (also known as a fence, enclosure, or barrier) is a structure installed at a doorway or passageway to provide security and divide space, preventing unauthorized personnel or animals from entering a specific area.

[0003] The existing gate frame is usually rigid and cannot be disassembled or folded. While this design provides high strength and stability, it takes up a lot of space during transportation, making it inconvenient to transport. Utility Model Content

[0004] In view of this, the present invention provides a door frame to solve the problem that the overall frame of the existing door frame cannot be folded, resulting in a large space occupied during transportation and inconvenience for transportation.

[0005] This utility model provides a door frame, including at least one retractable structure; the retractable structure includes:

[0006] A frame comprising multiple rods, wherein the rods are sequentially hinged end to end to form a polygonal structure;

[0007] A locking structure is disposed on the frame, and the locking structure has a locked state and an unlocked state;

[0008] When the locking structure is in the locked state, the locking structure restricts the rotation between two adjacent rods so that the frame forms a first configuration with a fixed shape; when the locking structure is in the unlocked state, the two adjacent rods can rotate so that the frame forms a second configuration that can be folded; the volume of the second configuration is smaller than the volume of the first configuration.

[0009] The beneficial effects of the aforementioned gateposts are:

[0010] In the unlocked state, the frame can transform from a fixed first configuration to a smaller second configuration, significantly reducing the space occupied by the structure in the folded state and facilitating transportation and storage. The folded second configuration can be packaged in smaller boxes, reducing transportation costs.

[0011] When the locking structure is in the locked state, the rotation between adjacent rods is restricted, so that the frame forms a first configuration with a fixed shape, which ensures the stability and rigidity of the structure during use.

[0012] In one optional embodiment, four rods are provided, namely a first rod, a second rod, a third rod, and a fourth rod that are hinged together end to end. The first rod and the third rod are parallel to each other, the third rod is located above the first rod, and the second rod and the fourth rod are parallel to each other.

[0013] When the locking structure is in the locked state, the projection of the first configuration is a rectangle;

[0014] When the locking structure is in the unlocked state, the projection of the second configuration is a parallelogram.

[0015] The beneficial effects of the above technical solution are as follows: In the unlocked state, the frame changes from the first rectangular configuration to the second parallelogram configuration. The projected area of ​​the parallelogram after folding is smaller than the projected area of ​​the rectangle before folding, which significantly reduces the space occupied by the structure in the folded state, facilitates packaging and transportation, and reduces logistics costs.

[0016] In one alternative implementation, when the frame changes from the first configuration to the second configuration, the overall size of the frame decreases in the height direction and the overall size of the frame increases in the width direction, with the decrease in the overall size of the frame in the height direction being greater than the increase in the overall size in the width direction.

[0017] The beneficial effects of the above technical solution are as follows: when using a rectangular packaging box to package the frame, the length of the packaging box remains unchanged. Since the overall size of the frame is reduced in the height direction, which is greater than the size increase in the width direction, the size of the packaging box used is greatly reduced, thereby reducing transportation costs.

[0018] In one optional implementation, the locking structure includes:

[0019] At least one rivet is provided between two adjacent rods to position the two adjacent rods.

[0020] In one optional embodiment, a plurality of grid plates are hinged between the first rod and the third rod, each grid plate being parallel to the second rod and the fourth rod, and a gap being between adjacent grid plates.

[0021] In one alternative embodiment, at least one roller is provided at the bottom end of the first rod.

[0022] In one alternative implementation, the gate further includes:

[0023] A pulley structure, the pulley structure being adapted to be connected to a door frame, wherein the retractable structure is slidably assembled onto the pulley structure.

[0024] In one optional implementation, the retractable structure further includes:

[0025] The fifth rod is fixedly mounted on the top surface of the third rod and is adapted to slide with the pulley structure.

[0026] In one alternative embodiment, at least two retractable structures are provided, and two adjacent retractable structures are detachably connected.

[0027] The beneficial effects of the above technical solution are as follows: when transporting the entire gate, each retractable structure can be disassembled and then folded, thereby greatly reducing the space occupied and facilitating the transportation of the entire gate. Furthermore, the dimensions of the retractable structures can be set according to actual usage requirements, allowing control over the overall dimensions after assembly of each retractable structure.

[0028] In one optional embodiment, each of the first rods has a first insertion interface on its side, and the first insertion interfaces of two adjacent retractable structures are connected by a first pin and fixed by a first locking pin; the fifth rod has a second insertion interface on its side, and the second insertion interfaces of two adjacent retractable structures are connected by a second pin and fixed by a second locking pin.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] The specific embodiments of this utility model are described in detail below with reference to the gate frame of this utility model.

[0042] According to an embodiment of this utility model, a gate is provided, combined with Figures 1 to 7 As shown, the device includes at least one retractable structure. The retractable structure includes a frame 1 and a locking structure 3. The frame 1 includes multiple rods, which are sequentially hinged end-to-end to form a polygonal structure. The locking structure 3 is mounted on the frame 1 and has a locked state and an unlocked state. When the locking structure 3 is in the locked state, it restricts rotation between adjacent rods, allowing the frame 1 to form a first configuration with a fixed shape. When the locking structure 3 is in the unlocked state, adjacent rods can rotate, allowing the frame 1 to form a second foldable configuration. The volume of the second configuration is smaller than the volume of the first configuration.

[0043] The aforementioned collapsible structure offers the advantage of high space utilization. In the unlocked state, the frame can transform from a fixed first configuration to a smaller second configuration, significantly reducing the space occupied by the structure in the folded state and facilitating transportation and storage. The folded second configuration can be packaged in smaller boxes, reducing transportation costs.

[0044] The aforementioned retractable structure offers the advantage of high stability. When the locking structure is in the locked state, rotation between adjacent rods is restricted, causing the frame to form a fixed first configuration, thus ensuring the stability and rigidity of the structure during use.

[0045] This retractable structure can be applied to various occasions according to actual needs, such as doorways and display shelves. The frame and locking structure can be made of different materials to adapt to different application scenarios and technical requirements.

[0046] In a preferred embodiment, four rods are provided: a first rod 11, a second rod 12, a third rod 13, and a fourth rod 14, which are hinged end-to-end. The first rod 11 and the third rod 13 are parallel to each other, with the third rod 13 located above the first rod 11. The second rod 12 and the fourth rod 14 are parallel to each other. When the locking structure 3 is in the locked state, the projection of the first configuration is rectangular, ensuring the rigidity and stability of the structure during use. When the locking structure 3 is in the unlocked state, the projection of the second configuration is a parallelogram.

[0047] In this embodiment, in the unlocked state, the frame 1 changes from a first rectangular configuration to a second parallelogram configuration. The projected area of ​​the parallelogram after folding is smaller than the projected area of ​​the rectangle before folding, which significantly reduces the space occupied by the structure in the folded state, making it easier to package and transport, and reducing logistics costs.

[0048] In some embodiments, when the frame 1 changes from the first configuration to the second configuration, the overall height dimension of the frame 1 decreases, while the overall width dimension of the frame 1 increases. The decrease in height dimension is greater than the increase in width dimension. When the frame 1 is packaged in a rectangular box, the length of the box remains unchanged. Because the decrease in height dimension of the frame 1 is greater than the increase in width dimension, the size of the box used is greatly reduced, thereby lowering transportation costs.

[0049] In some embodiments, the locking structure 3 includes at least one rivet 31, which is disposed between two adjacent rods to position the two adjacent rods. More specifically, rivet holes 32 are respectively provided between two adjacent rods, so that the two rods can be directly fixed by the rivet 31 when it is necessary to fix the two rods. As a preferred embodiment, a rivet hole is provided at each of the left and right ends of the first rod 11, and a rivet hole is provided at the bottom end of the second rod 12 and the bottom end of the fourth rod 14. The first rod 11 and the second rod 12 are riveted and fixed by a rivet, and the first rod 11 and the fourth rod 14 are riveted and fixed by another rivet.

[0050] In this embodiment, the locking and unlocking states can be switched with simple operations, allowing users to quickly adjust the state of the structure and improving ease of use.

[0051] In some embodiments, a plurality of grid plates 2 are hinged between the first rod 11 and the third rod 13, each grid plate 2 being parallel to the second rod 12 and the fourth rod 14, and there is a gap between two adjacent grid plates 2.

[0052] In some embodiments, at least one roller 4 is provided at the bottom end of the first rod 11 to facilitate the overall movement of the frame 1 along the ground.

[0053] In some embodiments, the door frame further includes a pulley structure 5, which is adapted to be connected to the door frame. The retractable structure is slidably mounted on the pulley structure 5, thereby enabling the retractable structure to slide along the pulley structure 5 to realize the door opening and closing operation.

[0054] In some embodiments, the retractable structure further includes a fifth rod 15, which is welded and fixedly disposed on the top surface of the third rod 13, and the fifth rod 15 is adapted to be slidably fitted with the pulley structure 5.

[0055] As a preferred embodiment, combined with Figure 5 and Figure 6 As shown, at least two retractable structures are provided, and adjacent retractable structures are detachably connected. Therefore, when transporting the entire gate, each retractable structure can be disassembled and folded separately, significantly reducing space occupation and facilitating the transport of the entire gate. Furthermore, the dimensions of the retractable structures can be customized according to actual usage requirements to control the overall dimensions after assembly.

[0056] In some embodiments, each first rod 11 has a first insertion interface 16 on its side, and two adjacent retractable structures with first insertion interfaces 16 are connected by a first pin 18 and fixed by a first locking pin. The fifth rod 15 has a second insertion interface 17 on its side, and two adjacent retractable structures with second insertion interfaces 17 are connected by a second pin 19 and fixed by a second locking pin.

[0057] More specifically, taking the second pin 19 as an example, the second pin 19 has two first locking holes 191 on its side wall, and the third rod 13 has one second locking hole 192 on its side wall. The second locking hole 192 is connected to the second insertion interface. When the second pin 19 is inserted into the second insertion interface, a locking pin passes through the first locking hole 191 and the second locking hole 192, thereby locking the second pin 19 to the third rod 13. When it is necessary to disassemble the two adjacent retractable structures, only the two locking pins need to be removed.

[0058] The aforementioned door frame is a double-track door frame. When in use, it unfolds into a rectangle and rolls along the ground via rollers 4. When the door frame needs to be folded, it is folded into a parallelogram, compressing in the height direction and slightly increasing in the width direction, which greatly reduces the packaging size. In actual transportation, the door frame can be rotated 90° and combined with… Figure 8 As shown, the first rod 11 and the third rod 13 are placed in a vertical position before being packaged and transported.

[0059] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
