[0001] The present application relates to the technical field of port machinery transformation, and in particular to a side pressure hanging cone. Background Art

[0002] A frame container is a special container that has the top and side walls removed from an ordinary container, leaving only the bottom plate, end walls and four corner columns. It is suitable for loading extra-wide, extra-high and heavy goods with complex and irregular shapes, and plays an important role in the transportation of super-standard containers. In actual use, frame containers are stacked up and down, and the upper and lower frame containers are fixed by locks to prevent the containers from bumping, shifting or tipping over during transportation. Side pressure cones, also known as twist locks, are commonly used locks for fixed frame containers. There is a risk of falling off due to external forces, which not only causes the frame container to shift, but the falling side pressure cones will also damage the goods in the frame container, causing huge losses. Therefore, improvements are needed. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to describe the technical solutions in the embodiments of the utility model in detail. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0020] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] See Figures 1 to 3 As shown, a side-pressure hanging cone includes a lock shell 1 and a lock core 2. The lock core 2 includes a rotating shaft and an upper lock head and a lower lock head respectively arranged at both ends of the rotating shaft. A shaft hole is provided in the middle of the lock shell 1, the rotating shaft is rotatably arranged in the shaft hole, a reset torsion spring corresponding to the rotating shaft is arranged in the shaft hole, and a limit pin 3 is inserted between the lower lock head and the lock shell 1.

[0022] In this technical solution, the structures of the lock shell and the lock core can both utilize existing structures. Among them, the upper lock head and the lower lock head are perpendicular to each other, and in the original state of the lower lock head, it is parallel to the lock shell. The limit pin is a conventional optical axis structure, and when inserted between the lower lock head and the lock shell, it can limit the rotation of the lock core, thereby preventing the side-pressure hanging cone from accidentally falling off. When the side-pressure hanging cone needs to be disassembled and assembled, the limit pin is pulled out to rotate the lock core to complete the disassembly and assembly of the side-pressure hanging cone; when the upper lock head and the lower lock head are both parallel to the lock shell, a limit pin is arranged between the upper lock head and / or the lower lock head and the lock shell, and the rotation of the lock core can also be restricted; for the existing side-pressure hanging cones, without changing their overall structures, etc., they can be transformed and continue to be used; the structure of this side-pressure hanging cone is simple, and the rotation of the rotating shaft is restricted by the limit pin, thereby reducing the possibility of the side-pressure hanging cone accidentally falling off. The overall structure of the side-pressure hanging cone does not need to be changed, which is suitable for the transformation of existing side-pressure hanging cones.

[0023] Exemplarily, see Figure 1 and Figure 2 As shown, a first arc groove 21 is concavely provided in the end face of the lower lock head close to the lock shell 1, and a second arc groove 11 is concavely provided in the end face of the lock shell 1 close to the lower lock head. The first arc groove 21 and the second arc groove 11 form a plugging hole corresponding to the limit pin 3.

[0024] In this technical solution, the first arc groove and the second arc groove are coaxially arranged and form an insertion hole. The limit pin is slidably arranged in the insertion hole. The limit pin is located in the first arc groove and the second arc at the same time, which limits the rotation of the lock core and improves the safety of the side pressure cone.

[0025] For example, see Figures 1 to 3 As shown, an anti-dropout boss 4 is provided at one end of the side surface of the lock housing 1 close to the second arc groove, and an anti-dropout portion 31 slidably engaged with the anti-dropout boss 4 is provided at one end of the limiting pin 3 .

[0026] In this technical solution, after the limit pin is inserted into the plug-in hole, the anti-slip portion is clamped on the anti-slip boss to prevent the limit pin from slipping out of the plug-in hole due to bumps, etc., thereby improving the reliability of the use of the limit pin.

[0027] For example, see Figure 1 and Figure 2 As shown, the anti-dropping boss 4 is staggered with the plug-in hole.

[0028] In this technical solution, the anti-dropout boss is staggered with the plug-in hole in its axial direction to prevent the anti-dropout boss from interfering with the disassembly and assembly of the limit pin.

[0029] For example, see Figures 1 to 3 As shown, a stud 41 protrudes from one end of the anti-dropping boss 4 close to the lock housing 1 and is connected to the lock housing 1 .

[0030] In this technical solution, the anti-drop boss and the stud can directly utilize the existing hexagonal bolts to reduce production costs, and are connected to the lock housing by threaded connection to facilitate installation.

[0031] For example, see Figures 1 to 3 As shown, the anti-dropout boss 4 is spaced from the corresponding side surface of the lock housing 1 , and a slot for snapping into the anti-dropout boss 4 is provided in the anti-dropout portion 31 .

[0032] In this technical solution, the anti-slip portion is fixed to the corresponding end of the limit pin by welding or the like, and two teeth are protruding from the side to form a slot. After the limit pin is installed, the limit pin and the anti-slip portion are rotated to connect the slot to the anti-slip boss to prevent the limit pin from slipping. When the limit pin needs to be removed, the limit pin and the anti-slip portion are rotated to disengage the slot and the anti-slip boss, and the limit pin can be pulled out. The anti-slip boss 4 is spaced apart from the corresponding side of the lock shell 1 to accommodate the corresponding teeth.

[0033] For example, see Figure 1 As shown, a mounting surface corresponding to the anti-slip boss 4 is recessed at one end of the side of the lock housing 1 close to the second arc groove. When the anti-slip portion 31 is snapped onto the anti-slip boss 4, the end surface thereof facing away from the limit pin 3 does not protrude from the corresponding side of the lock housing 1.

[0034] In this technical solution, a plane is milled at the corresponding corner of the lock housing as the mounting surface for the anti-detachment boss, and threaded holes corresponding to the studs are machined in the mounting surface. The insertion hole is also within the range of the mounting surface. After the limit pin is installed, it does not protrude from the corresponding side of the lock housing, avoiding interference with the installation of the side pressure hanging cone and the frame container.

[0035] In summary, the side pressure hanging cone has a simple structure. By restricting the rotation of the rotating shaft with a limit pin, the possibility of accidental detachment of the side pressure hanging cone is reduced. The overall structure of the side pressure hanging cone does not need to be changed, and it is applicable to the transformation of the existing side pressure hanging cone.

[0036] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.

[0037] The above are only specific embodiments of the present application. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
