Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Moreover, repeated reference numerals or designations may be used in various embodiments. These iterations are merely for simplicity and clarity of describing the present invention, and are not intended to represent any correlation between the different embodiments or configurations discussed.
As shown in fig. 1-2, the present invention provides a corner fitting locking mechanism 2 for fixing a corner fitting 9 at the bottom of a container to a support frame or transportation equipment below, which in this embodiment includes a fixing frame 10 as shown in fig. 1, a platform or other container, etc. The container holder 10 is used for holding a container 90, and, in general, the container holder 10 includes a frame body 1 and the corner fitting locking mechanism 2, where the frame body 1 fixes the container 90 on the frame body 1 through the corner fitting locking mechanism 2.
The container 90 generally comprises corner fittings 9 arranged at the ends, and the corner fitting locking mechanism 2 fixes the corner fittings 9 and the frame body 1 through connection, so that the container 90 is fixed on the container fixing frame 10. Typically, the corner fitting locking mechanism 2 is used to secure four corner fittings 9 at the bottom of the container 90.
As shown in fig. 3, the corner fitting 9 is a generally rectangular square body with a hollow interior, and the corner fitting 9 includes a bottom wall 91, and a substantially oval through hole 92 is formed in the bottom wall 91.
As shown in fig. 4, in particular, the corner fitting locking mechanism 2 includes:
a base body 3;
the locking piece 4 comprises a lock head 41 and a connecting shaft 42 fixed with the lock head 41, and part of the connecting shaft 42 is accommodated in the seat body 3;
the rotary driving part 5 comprises a connecting rod sleeved and fixed on the radial outer side of the connecting shaft 42 and a rotary power source 51 for driving the connecting rod to enable the connecting shaft 42 to rotate along the axis of the connecting shaft, and the rotary power source 51 is fixed on the frame body 1;
the vertical driving element 6 comprises a pulling element 61 arranged along the axial direction of the connecting shaft 42 and connected with the connecting shaft, and a vertical power source 62 for driving the pulling element 61 to move along the axial direction of the connecting shaft 42, wherein the vertical power source 62 is fixed on the seat body 3.
The locking head 41 is substantially flat and hemispherical and has a pointed end, so that the locking head 41 can pass through the through hole 92 on the bottom wall 91 of the corner fitting 9 and be accommodated inside the corner fitting 9. If the lock head 41 is not firmly limited, a movable gap exists between the lock head 41 and the corner fitting 9, and in the process of supporting and turning over the container 90, the falling gravity of the container 90 is completely pressed on the lock head 41, so that strong shearing force is generated, and the lock head 41 is easily broken and accidents are easily caused.
However, in the present embodiment, after the lock head 41 is inserted into the corner fitting 9, the connecting shaft 42 is driven to rotate by the rotation power source 51, and the lock head 41 is also rotated by a certain angle so that it cannot move from the corner fitting 9 to the outside of the corner fitting 9. Then the lock 41 is tensioned towards the direction of the vertical power source 62 by the vertical power source 62, so that the distance between the lock 41 and the bottom wall 91 of the corner fitting 9 can be shortened, the lock 41 is prevented from loosening, the bottom wall 91 of the corner fitting 9 can also be firmly fixed between the lock 41 and the frame body 1, the shearing force caused by the falling of the container 90 in the process of overturning the container 90 is also avoided, and the operation process is safer and more reliable.
A locking hole (not shown) is formed through the frame body 1, and the connecting shaft 42 passes through the locking hole. The lock head 41 is arranged above the lock hole and is used for being connected and fixed with the corner piece 9, and the connecting rod, the pulling piece 61 and the like are arranged below the lock hole.
The base body 3 comprises two first fixing portions 31 fixed on the frame body 1 and a second fixing portion 32 fixed between the two first fixing portions 31, and the two first fixing portions 31 extend from one side of the frame body 1 departing from the corner fitting 9. The seat body 3 is used for protecting the connecting shaft 42, the pulling part 61 and the like so as to prevent external objects from directly colliding with the connecting shaft 42, the pulling part 61 and the like. Of course, the seat body 3 is not limited to the above structure, the seat body 3 plays a role of stability and protection, and if the seat body 3 is of other structures, the conditions of the present invention can be satisfied as long as the above purpose can be achieved.
In the present embodiment, the pulling member 61 is movably connected to the connecting shaft 42, but the pulling member 61 can still pull the connecting shaft 42, so that the rotation of the connecting shaft 42 will not drive the rotation of the pulling member 61 and the vertical power source 62.
Of course, if other methods are adopted, the pulling element 61 is fixed to the connecting shaft 42, and when the connecting shaft 42 is driven and rotated, the pulling element 61 is also driven to rotate, so as to achieve the purpose of the present invention. The vertical power source 62 is also fixed to the pulling member 61, and when the pulling member 61 is driven to rotate, the vertical power source 62 is also driven to rotate correspondingly.
As shown in fig. 4, the corner fitting locking mechanism 2 further includes a vertical limiting member 63, and the vertical limiting member 63 is fixed on the base 3 and located between the pulling member 61 and the locking head 41 to limit the displacement of the pulling member 61. Specifically, in the present embodiment, the vertical limiting member 63 is disposed on the first fixing portion 31 of the seat body 3. The vertical limiting member 63 determines the distance between the lock head 41 and the bottom wall 91 of the corner piece 9 by determining the moving distance of the pulling member 61, so as to ensure that the lock head 41 is completely and stably fixed on the bottom wall 91 of the corner piece 9. The vertical position-limiting member 63 is a photoelectric switch or a travel switch, and is connected to the control device of the container holder 10, so as to determine the displacement distance of the pulling member 61.
As shown in fig. 4, in the rotary driving member 5, the connecting rod includes a first rod 511 and a second rod 512 movably connected, and the first rod 511 and the second rod 512 are connected by a shaft pin, so that both the first rod 511 and the second rod 512 can rotate along the shaft pin. The first rod 511 is fixed to the radial outer side of the connecting shaft 42 in a sleeved manner and can rotate around the axis of the connecting shaft 42, and the rotary power source 51 is connected with the second rod 512 and can drive the second rod 512 to move along the axial direction of the second rod 512. Therefore, in the process of the axial movement, the second rod 512 can drive the first rod 511 to rotate around the axis of the connecting shaft 42, so as to drive the connecting shaft 42 to rotate.
An angle X is formed between the first rod 511 and the second rod 512, wherein X is more than or equal to 0 degrees and less than or equal to 90 degrees, so that the first rod 511 can be pulled by the second rod 512. Moreover, the angle X formed between the first rod 511 and the second rod 512 is an acute angle, 0 or a right angle, and if the angle X is too large, the length of the second rod 512 extending outward is too long, which is not favorable for the structure to be tight.
Since the rotation of the locking head 41 only needs to be within 180 ° to prevent the locking head 41 from falling out of the corner fitting 9, the rotation angle of the first lever 511 is also within 180 °. Typically, the angle of rotation of the locking head 41 and the first lever 511 is about 90 °.
The rotary power source 51 is any one of an oil cylinder, an air cylinder or an electric push rod, and the rotary power source 51 is converted into the rotary motion of the first rod 511 by controlling the linear motion of the second rod 512, so as to drive the connecting shaft 42 to rotate.
The corner fitting locking mechanism 2 further includes a rotation limiting member 52, and the rotation limiting member 52 is fixed on the base body 3 and located on the same horizontal plane with the connecting rod to limit the rotation angle of the connecting rod. Specifically, in the present embodiment, the rotation limiting member 52 is fixed to the first fixing portion 31 of the seat body 3 and corresponds to the first rod 511. The rotation limiting member 52 is a photoelectric switch or a travel switch, and is connected to the control device of the container holder 10, so as to determine the rotation angle of the first rod 511.
The corner fitting locking mechanism 2 is sequentially provided with a lock head 41, a connecting rod, a pulling piece 61 and a vertical power source 62 from top to bottom, the connecting shaft 42 connects the lock head 41, the connecting rod and the pulling piece 61 from top to bottom, and the structure is compact and simple.
In summary, the corner fitting locking mechanism 2 and the container fixing frame 10 comprising the same of the present invention can fix the container 90 on the container fixing frame 10 through the corner fitting locking mechanism 2. The rotary driving member 5 rotates the locking head 41 to movably fix the locking head 41 in the corner fitting 9. The vertical driving element 6 drives the pulling element 61 to pull the lock head 41 tightly, so that the gap between the lock head 41 and the bottom wall 91 of the corner element 9 is eliminated, the container 90 is pulled tightly in the longitudinal direction, the container 90 is prevented from loosening, and the safety in operation is improved.
It should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art will be able to make the description as a whole, and the embodiments may be appropriately combined to form other embodiments as will be appreciated by those skilled in the art.
