TECHNICAL FIELD

[0001] The present application relates to the technical field of mobile house frame structure, in particular to a splicing structure and splicing frame of an easily-assembled mobile house. BACKGROUND

[0002] With the continuous development of society, more and more mobile houses are needed in different places. For example, various outdoor temporary activities have increased a lot, such as various sports competitions, concerts, parties, etc. However, the municipal supporting toilet facilities are not perfect for such activities held outdoors. In order to facilitate people to go to the toilet, some temporary mobile toilet houses need to be set up. For example, on construction sites, temporary houses are needed, which generally use mobile houses. In order to facilitate the assembly of mobile houses, a mobile house of the prior art adopts a site splicing structure, and the mobile house is spliced by frame profiles, boards and accessories, etc. The profiles are spliced into a whole frame on site, then the boards are fixed on the frame, and the accessory parts are installed to assemble the finished mobile house.

[0003] For example, the Chinese patent No. CN208346991U of the prior art discloses a splicing type mobile house frame structure, which is a frame structure connected by a series of profiles. The frame structure includes a base frame, a top frame, and a stand column connecting structure connected between the base frame and the top frame. A bottom plate is installed on the base frame of the frame structure main body, a top cover is installed on the top frame of the frame structure main body, a color steel door plate is installed on one side of the frame structure main body, and color steel plates are installed on the remaining three sides. The splicing type frame structure is used to replace the previous welding type frame structure, which can be quickly spliced on site. In the disclosed splicing frame structure, the stand column and the cross beam are directly connected by bolts. When connecting, the cross beam needs to be supported to maintain the butt joint position, and the bolt needs to be twisted for a long time for connection operation, so that the cross beam needs to be supported for a long time, the labor intensity is large, the operation time is long, and the assembly efficiency is low. SUMMARY

[0004] The present application aims to solve the above technical problems and provide a splicing structure and splicing frame of an easily-assembled mobile house.

[0005] In order to achieve the above-mentioned purpose, the following technical solutions are adopted: A splicing structure of an easily-assembled mobile house, comprising a stand column and a cross beam, a first threaded hole is formed in the side wall of the stand column, a first locking bolt is connected in the first threaded hole through a thread, the cross beam comprises a first sealing plate fixed at the end, a hanging hole is formed in the first sealing plate, the cross beam is hung and buckled on the first locking bolt through the hanging hole, and the cross beam is locked on the side wall of the stand column through the first locking bolt passing through the hanging hole.

[0006] Further, the hanging hole comprises a first locking hole and a first through hole which are in communication with each other, the first locking hole is located at an upper position of the first through hole, the slot width of the first locking hole is smaller than the diameter of the nut of the first locking bolt and larger than the diameter of the stud of the first locking bolt; the first through hole has a width larger than the diameter of the nut of the first locking bolt, so that the nut of the first locking bolt can pass through the first through hole, but the nut cannot pass through the first locking hole.

[0007] Further, the first locking hole is a waist-shaped hole, and the first through hole is a circular arc-shaped hole.

[0008] Further, at least two hanging holes are formed on each first sealing plate at the connection between the cross beam and the column, and the same number of first locking bolts as the number of the hanging holes are arranged on the column.

[0009] Further, a first threading hole is formed on the first sealing plate, a second threading hole is formed on the column, and the first threading hole and the second threading hole are oppositely arranged so that the electric wire in the cross beam passes through the column between the first threading hole and the second threading hole and is arranged in the adjacent cross beam.

[0010] Further, a second locking hole is formed on the first sealing plate, a second threaded hole coaxial with the second locking hole is formed on the column, a second locking bolt passing through the second locking hole is threadedly connected to the second threaded hole, and the second locking bolt locks the sealing plate to the side wall of the column.

[0011] A splicing frame of an easily-assembled mobile house adopts the above splicing structure and comprises the columns and the cross beams as described above; the cross beam comprises a top cross beam close to the upper end of the column and a bottom cross beam close to the lower end of the column, the column is provided with four columns, the cross beam and the column form a rectangular frame structure, and the cross beam and the column are both hollow profiles.

[0012] Further, the top cross beam is provided with two layers in an up-down manner, and the bottom cross beam is provided with two layers in an up-down manner.

[0013] Further, the upper end of the column is fixedly connected with an upper end plate, a third threaded hole is formed on the upper end plate, and the third threaded hole at the upper end of the column is used for connecting a lifting hook.

[0014] Further, the lower end of the column is fixedly connected with a lower end plate, a fourth threaded hole is formed on the lower end plate, and the fourth threaded hole at the lower end of the column is used for mounting a roller assembly.

[0015] Further, a forklift hole passing through the front and the back is formed on the bottom cross beam, and the forklift hole is arranged on the bottom cross beam in the form of a knock-out hole.

[0016] The present invention provides an easy-to-assemble mobile house splicing structure and splicing frame, which has the following beneficial effects: By threading a first locking bolt onto the column, the crossbeam is hung on the first locking bolt through the hanging hole, and then the crossbeam and column are locked by tightening the first locking bolt. During assembly, the crossbeam is briefly supported and suspended on the first locking bolt before tightening the first locking bolt. Since the first locking bolt is pre-installed on the column, the subsequent tightening time is shortened, thereby shortening the time for supporting the crossbeam during the assembly process. This avoids the long time required for bolt tightening and crossbeam support operations required for direct bolt connection between the crossbeam and column in existing methods, reducing the time for aligning and installing the crossbeam and improving installation efficiency. The column and crossbeam are connected by bolts, which is convenient for assembly and disassembly can be achieved by loosening the bolts, thus facilitating disassembly and relocation.

[0019] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] It should be noted that in the embodiments of the present invention, all directional indications (such as up-down-left-right-forward-backward...) are only used to explain the relative positional relationship and movement between the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0022] like Figures 1-4 As shown, an easy-to-assemble mobile house assembly structure includes a column 1 and a crossbeam 2. The column 1 has a first threaded hole 11 on its side wall, and a first locking bolt 3 is threaded into the first threaded hole 11. The crossbeam 2 includes a first sealing plate 21 fixed at its end, and a hanging hole 22 is provided on the first sealing plate 21. The crossbeam 2 is hooked onto the first locking bolt 3 through the hanging hole 22, and the first locking bolt 3 passes through the hanging hole 22 to lock the crossbeam 2 onto the side wall of the column 1.

[0023] Using the above technical solution, the first locking bolt 3 is threaded onto the column 1, and the crossbeam 2 is hung on the first locking bolt 3 through the hanging hole 22. Then, the crossbeam 2 is locked to the column 1 by tightening the first locking bolt 3. During assembly, the crossbeam 2 is briefly supported and suspended on the first locking bolt 3 before the first locking bolt 3 is tightened. No further manual support is required; the first locking bolt 3 provides support. Since the first locking bolt 3 is pre-installed on the column 1, the subsequent tightening time is shortened, thereby reducing the time required to support the crossbeam 2 during assembly. This avoids the long bolt tightening and manual support required in existing methods where the crossbeam 2 is directly connected to the column 1, reducing the alignment and installation time for the crossbeam 2 and improving installation efficiency. The column 1 and crossbeam 2 are connected by bolts, making assembly convenient, and disassembly is achieved by loosening the bolts, facilitating disassembly and transfer. It should be noted that the first threaded hole 11 can be formed by tapping directly on the side wall of the column 1, or by welding a threaded nut to the inner wall of the column 1.

[0024] Specifically, the hanging hole 22 includes a first locking hole 221 and a first through hole 222 that are interconnected. The first locking hole 221 is located above the first through hole 222. The groove width of the first locking hole 221 is smaller than the diameter of the nut 31 of the first locking bolt 3 and larger than the diameter of the stud of the first locking bolt 3. The width of the first through hole 222 is larger than the diameter of the nut 31 of the first locking bolt 3, so that the nut 31 of the first locking bolt 3 can pass through the first through hole 222 but the nut 31 cannot pass through the first locking hole 221. The nut 31 is the head structure of the first locking bolt 3. The diameter of its inscribed circle is larger than the diameter of the screw in the first locking bolt 3. By setting a first through hole 222 below the first locking hole 221, when the crossbeam 2 is suspended, the nut 31 of the first locking bolt 3 extends through the first through hole 222 to the side of the sealing plate near the inside of the crossbeam 2. The crossbeam 2 moves downward, causing the screw in the first locking bolt 3 to be inserted into the first locking hole 221. Then, the first locking bolt 3 is tightened, so that the nut 31 is clamped in the position of the first locking hole 221, so that the first sealing plate 21 is attached and clamped to the column 1, thereby locking the crossbeam 2 and the column 1.

[0025] Specifically, the first locking hole 221 is an oblong hole, and the first through hole 222 is an arc shape. The connected first locking hole 221 and the second locking hole 24 form a gourd-shaped hanging hole 22 structure. The crossbeam 2 is suspended and fixed through the gourd-shaped hanging hole 22. During the fixing process, the nut 31 of the first locking bolt 3 passes through the arc-shaped first through hole 222, and then the screw in the first locking bolt 3 is inserted into the oblong hole 221. The first locking bolt 3 is tightened, and the crossbeam 2 and the column 1 are locked together through the first locking hole 221 and the first locking bolt 3.

[0026] It should be noted that in some embodiments, the first through hole 222 can be configured as an elongated or rectangular structure, which is used to allow the nut 31 of the first locking bolt 3 to extend through the first through hole 222 to the side of the sealing plate near the inside of the crossbeam 2.

[0027] Specifically, each first sealing plate 21 at the connection between the crossbeam 2 and the column 1 has at least two hanging holes 22, and the column 1 has the same number of first locking bolts 3 as the hanging holes 22. Each end connection has two hanging holes 22 and matching first locking bolts 3, thus forming two sets of hooking points to prevent the crossbeam 2 from rotating when hooked onto the first locking bolts 3, thereby maintaining the stability of the crossbeam 2 assembly.

[0028] Specifically, the first sealing plate 21 has a first wire-passing hole 23, and the column 1 has a second wire-passing hole 12. The first wire-passing hole 23 and the second wire-passing hole 12 are arranged opposite to each other so that the wires in the crossbeam 2 pass through the column 1 between the first wire-passing hole 23 and the second wire-passing hole 12 and are routed to the adjacent crossbeam 2. By providing wire-passing holes, it is convenient to run wires from inside the crossbeam 2 and the column 1.

[0029] Specifically, the first sealing plate 21 has a second locking hole 24, and the column 1 has a second threaded hole 13 coaxial with the second locking hole 24. The second threaded hole 13 is threadedly connected to a second locking bolt 4 passing through the second locking hole 24, and the second locking bolt 4 locks the sealing plate to the side wall of the column 1. The crossbeam 2 is suspended and locked by the first locking bolt 3, and the crossbeam 2 is locked by the second locking bolt 4, thereby improving the stability of the lock between the crossbeam 2 and the column 1.

[0030] In some embodiments, such as Figure 5 , Figure 6 As shown, an easy-to-assemble mobile house frame adopts the aforementioned easy-to-assemble mobile house assembly structure, including the columns 1 and beams 2 as described above. The beams 2 include a top beam 2a near the upper end of the columns 1 and a bottom beam 2b near the lower end of the columns 1. Four columns 1 are provided. The beams 2 and columns 1 form a rectangular frame structure. Both the beams 2 and columns 1 are made of hollow profiles. By splicing the beams 2 and columns 1 into a rectangular frame, composite panels are laid around the perimeter, top, and bottom of the frame during the assembly of the mobile house, thereby forming a mobile house with an internal cavity. It can be used as the main body of an outdoor toilet, equipment room, or temporary housing, and has strong versatility.

[0031] Specifically, such as Figure 6As shown, a vertically arranged outward flange 6 is fixedly connected to the column 1, and a horizontally arranged outward flange 6 is fixedly connected to the beam 2. The outward flange 6 is used to fix and limit the composite panel of the enclosed mobile house. At the same time, the composite panel can be secondary fixed to the outward flange 6 with self-tapping screws, which can improve the fixing strength of the composite panel and ensure the stability of the installation and connection of the composite panel.

[0032] In some embodiments, such as Figure 7 As shown, the top crossbeam 2a has two layers, and the bottom crossbeam 2b has two layers. By setting two layers of top crossbeams 2a, composite panels can be installed on the frame during the assembly of the mobile house, thus allowing a top partition to be set on the roof to accommodate electrical wiring after the mobile house is assembled; and by setting two layers of bottom crossbeams 2b, a bottom partition to accommodate bottom water pipes or a water tank can be set at the bottom after the mobile house is assembled.

[0033] In some embodiments, such as Figure 5 As shown, an upper end plate 14 is fixedly connected to the upper end of the column 1. A third threaded hole 141 is provided on the upper end plate 14, and this third threaded hole 141 is used to connect a lifting hook. Thus, a lifting hook can be installed on the column 1 as needed, facilitating the lifting of the entire unit. Alternatively, a plate can be connected through the third threaded hole 141, and the plate can be connected to an adjacent mobile house, thereby fixing two adjacent mobile houses together to form a series of interconnected mobile houses.

[0034] In some embodiments, such as Figure 6 As shown, a lower end plate 15 is fixedly connected to the lower end of the column 1. A fourth threaded hole 151 is provided on the lower end plate 15. The fourth threaded hole 151 at the lower end of the column 1 is used to install and connect the roller assembly. The fourth threaded hole 151 provides a spare assembly roller, which can be used to install the roller assembly at the bottom of the column 1 as needed, thereby facilitating the movement of the mobile house by means of the rollers.

[0035] In some embodiments, such as Figure 8 As shown, the bottom crossbeam 2b has a through forklift hole 5, which is a knockout hole. The forklift hole 5 is provided on the bottom crossbeam 2b to facilitate the lifting and moving of the mobile house by forklift. The knockout hole 5 eliminates the need to knock it out when not in use, leaving no exposed opening. When the forklift hole 5 is needed, it is knocked out to expose it, providing a passage for the forklift forks to insert.

[0036] The parts not covered in this technical solution can be implemented using existing technologies.

[0037] The foregoing has shown and described the basic principles, main features, and characteristics of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed. The scope of protection of this invention includes the appended claims and their equivalents.
