Description

Technical Field

[0001] This utility model generally relates to the technical field of container structures, and more specifically to a detachable short column assembly and a container having the same. Background Technology

[0002] A rack-mount container, a type of container, consists of a loading platform and end frames at both ends of the platform. The height of a rack-mount container is fixed, meeting the transportation requirements of most conventionally tall cargoes. Terminals can perform lifting and stacking operations on heavily loaded rack-mount containers. However, for some taller cargoes transported using collapsible containers, the cargo will exceed the top of the rack-mount container, making it impossible for terminals to lift and stack heavily loaded collapsible containers. To meet the transportation requirements of these cargoes, existing technology generally involves installing removable extender columns at the top of the end frames to extend the length of the end frames, thereby increasing the loading height of the rack-mount container.

[0003] The existing detachable short column includes a column section and a locking mechanism. The column section includes a corner piece, a short column, and a stacking plate. The locking mechanism includes a rotary lock shaft, a wedge block, a strip, and a bolt. The stacking plate has a rotary lock shaft hole. The rotary lock shaft includes a head and a tail. The tail end of the rotary lock shaft can pass through the rotary lock shaft hole into the short column body, and the tail end has a wedge hole that matches the wedge block. The head of the rotary lock shaft is used to connect with the container. When the tail end of the rotary lock shaft is inserted into the short column, the wedge block can be horizontally inserted into the wedge hole of the rotary lock shaft from the open side of the short column. The small end of the wedge block has a horizontally threaded hole, and the bolt can be screwed into or out of this threaded hole, allowing the wedge block to extend and retract within the wedge hole of the rotary lock shaft, thereby causing vertical displacement of the rotary lock shaft. The large end of the wedge block has a horizontally through hole that connects with the threaded hole.

[0004] The existing wedge block is relatively long overall, and the long wedge surface results in a large amount of machining. The tail of the wedge surface of the wedge block is high and does not contact the wedge hole of the rotary lock shaft during the movement. The threaded hole and through hole are parallel to the length direction of the wedge block. The threaded hole and through hole are relatively long, resulting in a large amount of machining and a long processing time.

[0005] Therefore, there is a need to provide a detachable short column assembly and a container having therein to at least partially solve the above problems. Utility Model Content

Detailed Implementation

[0042] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that embodiments of the present invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the present invention.

[0043] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art.

[0044] like Figures 1 to 8 As shown, this utility model provides a detachable short column assembly 100, which is installed on a container 200, which includes a platform-type container 202 and a rack-type container 203. The installation of the detachable short column assembly 100 effectively increases the cargo capacity of the container 200.

[0045] like Figures 1 to 8 As shown, the detachable short column assembly 100 according to this utility model includes a fixing part and a locking part. The fixing part includes a short column 2 and a stacking plate 3. The locking part includes a rotary lock shaft 4 and a wedge block 5.

[0046] like Figures 1 to 8 As shown, in a preferred embodiment of the present invention, the short column 2 has a hollow cavity 21 inside.

[0047] The stacking plate 3 is located at the bottom end of the short column 2, and the stacking plate 3 has a first through hole 31.

[0048] The rotary lock shaft 4 has a wedge-shaped hole 41. The top end 4a of the rotary lock shaft 4 extends into the hollow cavity 21 of the short column rod 2 through the first through hole 31. The detachable short column rod assembly 100 is rotated so that the bottom end of the rotary lock shaft 4 is locked against the top wall of the top corner piece 201.

[0049] A wedge block 5 is disposed within the hollow cavity 21 of the short column 2. The first end 5a of the wedge block 5 has a slot 51 with an opening facing the top of the hollow cavity 21. The second end 5b of the wedge block 5 is adapted to the wedge hole 41 of the rotary lock shaft 4. A first through hole 31 is provided on the stacking plate 3, through which the top of the rotary lock shaft 4 can pass into the hollow cavity 21 of the short column 2. A wedge hole 41 is provided in the upper region of the rotary lock shaft 4, which matches the wedge block 5. The second end 5b of the wedge block 5 has a first threaded hole 53 extending along the length direction of the wedge block 5. A bolt 6 is inserted into the hollow cavity 21 of the short column 2 and connected to the first threaded hole 53. The detachable short column assembly 100 of this utility model can reduce weight by constructing the above-mentioned empty groove 51 on the wedge block 5, which facilitates installation, saves time and effort, and at the same time greatly shortens the length of the top inclined surface of the wedge block 5, effectively shortens the processing time of the wedge block 5, improves the overall processing efficiency of the detachable short column assembly 100, and saves economic costs.

[0050] The detachable short column assembly 100 of this utility model eliminates the need for guide pins (not shown in the figure), strips (not shown in the figure), and socket head cap screws (not shown in the figure) in the prior art. The detachable short column assembly 100 of this utility model eliminates the need for installation and gluing of strips and socket head cap screws, and the notch in the short column 2 is eliminated. The steel cost, processing cost, and assembly time required for the detachable short column assembly 100 of this utility model are correspondingly reduced.

[0051] like Figure 5 As shown, in some preferred embodiments of this utility model, the wedge block 5 includes a first end 5a, a second end 5b, and a connecting end 5c connecting the first end 5a and the second end 5b. The connecting end 5c is constructed as the bottom wall of the slot 51. It should be noted that the first end 5a is the larger end relative to the original end before the slot 51 was removed, and the second end 5b is the smaller end relative to the original end before the slot 51 was removed.

[0052] like Figure 5 As shown, in some preferred embodiments of the present invention, the second end 5b of the wedge block 5 has a first threaded hole 53 extending along the length direction of the wedge block 5.

[0053] The tail end of the first end 5a has a second through hole 54, the central axis of which coincides with the central axis of the first threaded hole 53. Since the central axis of the second through hole 54 coincides with the central axis of the first threaded hole 53, the second through hole 54 can be machined simultaneously with the threaded hole 53. Therefore, the machining efficiency of the first threaded hole 53 and the second through hole 54 is effectively improved, and the two holes can be machined simultaneously, effectively shortening the machining time of the holes.

[0054] like Figure 1 and Figure 2 As shown, in some preferred embodiments of this utility model, the detachable short column assembly 100 further includes a bolt 6, which passes through the short column 2 and is connected to the first threaded hole 53. The tail 61 of the bolt 6 is disposed in the slot 51 of the wedge block 5. By screwing in or out the bolt 6, the wedge block 5 can be extended or retracted in the wedge hole 41 of the rotary lock shaft 4, thereby causing the rotary lock shaft 4 to be displaced in the vertical direction, so as to facilitate the engagement of the rotary lock shaft 4 with the top wall of the corner piece 201.

[0055] like Figure 2 and Figure 3 As shown, in some preferred embodiments of this utility model, the detachable short column assembly 100 further includes a blocking washer 7. The blocking washer 7 is disposed in the slot 51 and adapted to the tail 61 of the bolt 6. The blocking washer 7 is adapted to reciprocate along the length direction of the slot 51. The blocking washer 7 is installed in the slot 51, thereby effectively preventing the blocking washer 7 from falling off during the disassembly of the bolt 6.

[0056] like Figure 3 As shown, in some preferred embodiments of this utility model, the outer diameter of the blocking washer 7 is larger than the inner diameter of the first threaded hole 53 and the second through hole 54, respectively. Thus, when tightening or loosening the bolt 6, even if the bolt 6 reciprocates along the length of the slot 51, the outer diameter of the blocking washer 7, being larger than the inner diameter of the first threaded hole 53 and the second through hole 54, provides a good stopping effect, preventing the bolt 6, wedge block 5, and rotary lock shaft 4 from falling off during left-right movement.

[0057] like Figure 3 As shown, in some preferred embodiments of the present invention, the tail 61 of the bolt 6 has a third threaded hole 611 extending axially.

[0058] The detachable short rod assembly 100 also includes a fastener 8, which is adapted to the third threaded hole 611. After the bolt 6 is inserted into the wedge block 5, it is threaded into the first threaded hole 53. The tail 61 of the bolt 6 is set in the empty groove 51. The blocking washer 7 is placed between the fastener 8 and the bolt 6. The fastener 8 is extended into the empty groove 51 through the second through hole 54 and tightened into the third threaded hole 611, thereby realizing the installation of the blocking washer 7.

[0059] Preferably, the fastener 6 can be a bolt, rivet, etc.

[0060] The detailed assembly process of the detachable short column assembly 100 provided by this utility model is as follows: A first through hole 31 is provided on the stacking plate 3. The top end of the rotary lock shaft 4 can pass through the first through hole 31 and enter the hollow cavity 21 of the short column 2. A wedge-shaped hole 41 is provided in the upper part of the rotary lock shaft 4. The wedge-shaped hole 41 matches the wedge block 5. The short column 2 has an opening 22. The wedge block 5 is inserted into the wedge-shaped hole 41 through the opening 22. The second end 5b of the wedge block 5 has a first threaded hole 53 extending along the length direction of the wedge block 5. The bolt 6 passes through the short column 2 and connects with the first threaded hole 53. The second through hole 54 of the wedge block 5 is the threaded bottom hole of the first threaded hole 53. The fastener 8 can pass through the second through hole 54 and the washer 7 and connect with the third threaded hole 611 of the tail 61 of the bolt 6. The washer 7 is located in the empty groove 51. Finally, the side sealing plate 9 is covered.

[0061] like Figure 1 , Figure 2 and Figure 7 As shown, in some preferred embodiments of the present invention, one side of the short column 2 has an opening 22 for inserting the wedge block 5.

[0062] The detachable short post assembly 100 also includes a side sealing plate 9, which covers the opening 22. The side sealing plate 9 can be snapped onto the short post 2 with rubber clips to seal the opening 22.

[0063] like Figure 5 As shown, in some preferred embodiments of the present invention, the detachable short column assembly 100 further includes a first transition surface 52, which is disposed in the connection area between the side end face of the first end 5a and the bottom end face of the connecting end 5c.

[0064] The second transition surface 52a is located in the area where the side end face of the second end 5b connects to the bottom end face of the connecting end 5c. The arrangement of the first transition surface 52 and the second transition surface 52a allows the wedge block 5 to play a better guiding role when moving, preventing the wedge block 5 from getting stuck on the edge of the first through hole 31 of the stacking plate 3, and making the movement smoother.

[0065] In some preferred embodiments of this utility model, the detachable short column assembly 100 further includes an upper end sealing plate 10. The upper end sealing plate 10 is disposed at the upper end of the hollow cavity 21 of the short column 2 and is adapted to prevent the rotary lock shaft 4 from moving vertically along the short column 2. The outer contour dimensions of the upper end sealing plate 10 are adapted to the inner contour dimensions of the hollow cavity 21 of the short column 2. The upper end sealing plate 10 can be fixedly disposed at the upper end of the hollow cavity 21 of the short column 2 by welding. The arrangement of the upper end sealing plate 10 can effectively prevent the rotary lock shaft 4 from moving vertically along the short column 2.

[0066] In some preferred embodiments of this invention, the detachable short column assembly 100 further includes a corner plate 1, which is disposed at the top end of the short column 2. The corner plate 1 has a waist-shaped hole 11, which communicates with the hollow cavity 21 inside the short column 2. Compared to the prior art which uses a corner piece at the top end of the short column 2, the detachable short column assembly 100 of this invention replaces the corner piece with the corner plate 1. During hoisting, the lifting device extends through the waist-shaped hole 11 into the hollow cavity 21 of the short column 2 and is engaged with the inner side wall of the corner plate 1, thereby achieving the hoisting function. The detachable short column assembly 100 of this invention replaces the corner piece (not shown in the figure) in the prior art with the corner plate 1, thereby effectively reducing the overall weight of the detachable short column assembly 100, making installation easier and rotating the bolt 6 less strenuous.

[0067] It should be noted that the corner plate 1 can be installed on the top surface of the short column 2 by welding.

[0068] According to a second aspect of the present invention, a container is also provided, including the detachable short column assembly 100 described in the above embodiments. The container 200 can be a platform-type container 202 or a rack-type container 203.

[0069] In summary, according to the detachable short column assembly 100 of this utility model, the stacking plate 3 is provided with a first through hole 31, through which the top end of the rotary lock shaft 4 can pass into the hollow cavity 21 of the short column 2. A wedge-shaped hole 41 is provided in the upper region of the rotary lock shaft 4, which matches the wedge block 5. The second end 5b of the wedge block 5 has a first threaded hole 53 extending along the length direction of the wedge block 5. The bolt 6 passes into the hollow cavity 21 of the short column 2 and connects with the first threaded hole 53. The detachable short column assembly 100 of this utility model, by constructing the aforementioned slot 51 on the wedge block 5, can reduce weight, facilitate installation, and save time and effort during installation. At the same time, it also greatly shortens the length of the top inclined surface of the wedge block 5, effectively shortening the processing time of the wedge block 5, improving the overall processing efficiency of the detachable short column assembly 100, and saving economic costs.
