Description

Technical Field

[0008] ,

[0001] The utility model relates to the technical field of door and window transportation, in particular to a door and window transportation rack. Background Art

[0002] In the production, sales and installation links of doors and windows, the transportation of doors and windows is a crucial link. Since doors and windows are mostly structures composed of glass and frames, the glass is fragile and the frames are easy to deform, and they are extremely prone to damage during transportation due to bumps, collisions, vibrations, etc.

[0003] In the traditional transportation method, the fixation of doors and windows on the transportation rack is not firm enough. Usually, the self-weight and the slopes provided by the transportation rack are used. In the case of long-distance transportation or poor road conditions, even with only the self-weight and the slopes of the transportation rack, there is still a risk of displacement and falling damage, resulting in a significant increase in the probability of door and window damage, bringing unnecessary economic losses to production enterprises and transportation units.

[0004] Therefore, there is an urgent need for a door and window transportation rack that can effectively fix doors and windows to prevent displacement and damage during transportation. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problems in the background art and propose a door and window transportation rack.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A door and window transportation rack includes four columns and a supporting basic truss. The four columns are divided into two groups. Between the upper and lower ends of each group of columns, a reinforcing truss and the basic truss are respectively connected and reinforced by bolts. Short connecting columns are arranged between the two opposite basic trusses. The short connecting column is a concave-shaped steel with a plurality of limiting holes on its outer surface. A long connecting column is connected between the two short connecting columns by bolts. The two ends of the long connecting column are thin columns. The thin columns of the long connecting column are connected to control the distance between the two groups of columns by inserting bolts into the limiting holes at any position on the inner wall of the short connecting column and sliding. A supporting member is arranged between the column and the basic truss to reinforce the connection between the column and the basic truss. Between the columns on the opposite sides, a placing truss is connected by bolts. The two placing trusses are used to place the doors and windows lying flat. A limiting mechanism for preventing the displacement and falling of the doors and windows during transportation is arranged on the placing truss.

[0007] Preferably, the supporting member includes two wide sleeve plates and a short sliding plate. The two ends of the short sliding plate are respectively slidably connected to the wide sleeve plates. A plurality of limiting holes are arranged on the short sliding plate. The two wide sleeve plates are controlled to move along the outer surface of the short sliding plate to any position of the limiting holes by inserting bolts to control the length of the whole supporting member. The ends of the two wide sleeve plates far away from the short sliding plate are respectively movably connected to the column and the basic truss.

[0008] Preferably, the side wall of the column is provided with a number of fixing holes, and the position of the connection node between the wide sleeve plate and the column is controlled by the bolts inserted into the fixing holes on the column through the No. 2 connecting block. The foundation truss is detachably connected to one end of the wide sleeve plate through the No. 1 connecting block using bolts.

[0009] Preferably, the interior of the placement truss is provided with a through groove, the outer surface of the placement truss is provided with a first limiting groove connecting the through groove on both sides, and a circular hole is provided in the first limiting groove on one side of the placement truss.

[0010] Preferably, the limiting mechanism includes a mounting part for connecting to the placement truss and a limiting part for limiting the movement of doors and windows.

[0011] Preferably, the mounting part includes a long threaded pin, on which a limiting plate is connected. The limiting plate on the long threaded pin is aligned with the round hole on the truss and inserted. The long threaded pin moves along the first limiting groove of the truss and drives the limiting plate to move to any position inside the groove, where it is limited by a nut.

[0012] Preferably, the limiting part includes a mounting plate, which is fixed to one end of a long screw. Both sides of the mounting plate are provided with arc-shaped hoops. The inside of the arc-shaped hoops is hollow. An extrusion member is slidably connected to the hollow part of the arc-shaped hoops and extends to the outside of the arc-shaped hoops. An extrusion rod is threadedly connected to the inside of the arc-shaped hoops. Rotating the extrusion rod extends into the inside of the arc-shaped hoops and extrudes the extrusion member inside the arc-shaped hoops, controlling the distance by which the extrusion member extends out of the arc-shaped hoops.

[0013] Preferably, the extrusion rod is a screw, the extrusion component is a rubber pad, and the side in contact with the door or window is a rough surface.

[0014] Preferably, the limiting part includes a mounting base and an elastic strap for binding the door / window to the placement truss for limiting. The mounting base is fixed to one end of a long screw. A rotating rod is rotatably connected to the mounting base. The outer surface of the rotating rod has a second limiting groove. A rotating cylinder is fitted on the outer surface of the rotating rod. The outer surface of the rotating cylinder has several third limiting grooves.

[0016] In summary:

[0017] The door and window transport rack provided by this utility model, through its scientific and reasonable structural design, can effectively solve the problems of unstable fixing and easy displacement and damage in traditional door and window transportation. The specific beneficial effects are as follows:

[0018] The equipped limiting mechanism can securely limit the doors and windows in two ways: one is to use the squeezing rod to push the rubber pad (rough surface) tightly against the doors and windows, increasing friction and preventing slippage during transportation; the other is to use elastic straps to firmly bind the doors and windows to the placement truss, and with the clamping structure of the limiting component, ensure stable binding force.

[0019] The columns and the foundation truss are reinforced by support members. The two ends of the support members are movably connected to the columns and the foundation truss, respectively, forming a stable triangular support structure, which enhances the overall load-bearing capacity and deformation resistance of the transport frame.

[0020] The reinforced truss further enhances the connection strength between the upper and lower ends of the column, preventing the frame from loosening due to excessive stress during transportation, ensuring the structural stability of the transport frame when carrying doors and windows, and reducing the safety hazard of doors and windows falling.

[0028] Example 1: Refer to Figure 1-4 As shown, this utility model provides a technical solution: a door and window transport frame, including four columns 1 and a matching base truss 2. The four columns 1 are divided into two groups. The upper and lower ends of each group of columns 1 are respectively connected by bolts to reinforce the truss 4 and the base truss 2. Short connecting columns 5 are provided between the two base trusses 2. The short connecting columns 5 are U-shaped steels with several limiting holes on their outer surface. Long connecting columns 6 are connected between the two short connecting columns 5 by bolts. The two ends of the long connecting columns 6 are thin columns. The thin columns of the long connecting columns 6 are connected by bolts inserted into the limiting holes on the inner wall of the short connecting columns 5 to slide to any position to control the spacing between the two groups of columns 1. Support members 3 are provided between the columns 1 and the base truss 2 to reinforce the connection between the columns 1 and the base truss 2. Placement trusses 7 are connected between the columns 1 on opposite sides by bolts. The two placement trusses 7 are used to place the doors and windows lying flat. The placement trusses 7 are provided with limiting mechanisms 8 to prevent the doors and windows from shifting and falling during transport.

[0029] The support member 3 includes two wide sleeve plates 31 and a short slide plate 32. The two ends of the short slide plate 32 are slidably connected to the wide sleeve plates 31. The short slide plate 32 is provided with several limiting holes. The two wide sleeve plates 31 are moved along the outer surface of the short slide plate 32 to any position by inserting bolts into the limiting holes to control the length of the entire support member 3. The ends of the two wide sleeve plates 31 away from the short slide plate 32 are movably connected to the column 1 and the foundation truss 2, respectively.

[0030] The side wall of column 1 has several fixing holes 11. The position of the connection node between the wide sleeve plate 31 and column 1 is controlled by the bolts inserted into the fixing holes 11 on column 1 through the second connecting block 33. The foundation truss 2 is detachably connected to one end of the wide sleeve plate 31 through the first connecting block 21 using bolts.

[0031] The interior of the truss 7 has a through groove 71, and the outer surfaces of the truss 7 have first limiting grooves 73 that connect to the through grooves 71 on both sides. The first limiting groove 73 on one side of the truss 7 has a round hole 72.

[0032] The limiting mechanism 8 includes a mounting part 81 for connecting to the placement truss 7 and a limiting part for limiting the movement of doors and windows.

[0033] The mounting part 81 includes a long threaded pin 811, on which a limiting plate 812 is connected. The limiting plate 812 on the long threaded pin 811 is aligned with the round hole 72 on the placement truss 7 and inserted. The long threaded pin 811 moves along the first limiting groove 73 of the placement truss 7 and drives the limiting plate 812 to move to any position inside the through groove 71, where it is limited by a nut 813.

[0034] The limiting part includes a mounting plate 82, which is fixed to one end of a long screw pin 811. Both sides of the mounting plate 82 are provided with arc-shaped hoops 83. The inside of the arc-shaped hoops 83 is hollow. A pressing member 85 is slidably connected to the hollow part of the arc-shaped hoops 83 and extends to the outside of the arc-shaped hoops 83. A pressing rod 84 is threadedly connected to the inside of the arc-shaped hoops 83. Rotating the pressing rod 84 extends into the inside of the arc-shaped hoops 83 and presses the pressing member 85 inside the arc-shaped hoops 83, controlling the distance that the pressing member 85 extends out of the arc-shaped hoops 83, so as to firmly abut against the door and window and limit the door and window.

[0035] The extrusion rod 84 is a screw, and the extrusion part 85 is a rubber pad. The side that contacts the door and window is a rough surface. The rough surface of the rubber pad can increase the friction with the door and window when it comes into contact with it, so as to avoid large displacement of the door and window during transportation.

[0036] Example 2: Refer to Figure 5-6 As shown, the limiting part includes a mounting base 86 and an elastic strap 89 for limiting the door and window to the placement truss 7. The mounting base 86 is fixed to one end of a long screw pin 811. A rotating rod 87 is rotatably connected to the mounting base 86. A second limiting groove 871 is opened on the outer surface of the rotating rod 87. A rotating cylinder 88 is sleeved on the outer surface of the rotating rod 87. A number of third limiting grooves 881 are provided on the outer surface of the rotating cylinder 88. One end of the elastic strap 89 is inserted into the second limiting groove 871 by a limiting member, and the other end is wrapped around the rotating rod 87 several times and extends to the outside through the third limiting groove 881. After the door and window are wrapped and bound to the placement truss 7 several times, they are fixed by inserting the limiting member into the third limiting groove 881.

[0037] The limiting component includes a square rod 891, with an elastic strap 89 fixedly connected to the square rod 891. Both ends of the square rod 891 are hollow, and guide grooves 892 are formed on the outward-facing inner walls of the hollow sections on both sides. Protrusions 895 limit the movement of the guide grooves 892. An extension rod 894, which slides along the hollow inner wall of the square rod 891, is provided on one side of each protrusion 895. An elastic element 893 is positioned between the two extension rods 894. When the two protrusions 895 are pressed together, the elastic element 893 contracts, causing the extension rods 894 to retract into the square rod 891. At this point, the square rod 891 is inserted into the second limiting groove 871, releasing the restraint on the two protrusions 895. The elastic element 893 rebounds, the extension rod 894 resets and extends out of the square rod 891. At this point, the square rod 891 is blocked by the extension rod 894 and cannot detach from the second limiting groove 871. Thus, one end of the elastic strap 89 can be connected to the rotating rod 87. The step of inserting the limiting element into the third limiting groove 881 is the same as the step of inserting into the second limiting groove 871. The elastic element 893 is a spring, and the elastic strap 89 is an elastic band.

[0038] The working principle is as follows: When transporting doors and windows, the transport frame is first assembled. The foundation truss 2 is installed between two columns 1 using bolts. Then, the other two columns 1 and the foundation truss 2 are installed. The long connecting column 6 and the short connecting column 5 are connected by bolts through any limiting holes to control the distance between the two sets of columns 1 to adapt to the size of the transported doors and windows. At this time, the distance between the wide sleeve plate 31 and the short sliding plate 32 is adjusted so that one wide sleeve plate 31 is connected to any node of the column 1 by bolts, and the other wide sleeve plate 31 is installed at the first connecting block 21 of the foundation truss 2, thereby increasing the stability of the connection between the column 1 and the foundation truss 2. Then, the placement truss 7 is installed with bolts according to the thickness of the doors and windows. When the door frame is placed on the placement truss 7, a suitable limiting mechanism 8 (such as the limiting mechanism 8 in embodiment 1 or the limiting mechanism 8 in embodiment 2) is selected to limit the doors and windows, so as to avoid the risk of the doors and windows falling off the placement truss 7 during transportation.

[0039] The connecting components mentioned above are all available on the market. Therefore, the installation and welding between the connecting components are not related to innovation and will not be described in detail. Some components can also be obtained through private customization, so they will not be described in detail either.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
