Schematic truck safety lock

A truck security lock is illustrated in figures 1 to 2 and is used to capture the fasteners 60 of a cargo container.

Specifically, the truck safety lock comprises a base 10, and the base 10 is fixedly connected to the cargo box.

In particular, the truck safety lock further comprises a rotating member 20, and the rotating member 20 is rotatably arranged on the base 10.

Further, the rotating member 20 has a locking head 21 and a locking arm 22, the locking head 21 is rotatably connected to the base 10, wherein the locking arm 22 extends from one end of the locking head 21. It should be noted that the locking head 21 and the locking arm 22 are integrated, and one end of the locking arm 22 is pressed by external force to rotate the locking head 21 by a predetermined angle.

Further, the locking arm 22 has a connecting portion 221 and a holding portion 222, two ends of the connecting portion 221 are respectively connected to the locking head 21 and the holding portion 222, wherein the holding portion 222 extends vertically from one end of the connecting portion 221. It should be noted that the connecting portion 221 extends obliquely upward from one end of the lock head 21, and the holding portion 222 extends vertically from one end of the connecting portion 221, so that when the base 10 is attached to the surface of the cargo box, a distance is left between the holding portion 222 and the cargo box. Since a distance is left between the holding portion 222 and the container, a user can conveniently hold the holding portion 222 and further apply pressure to the holding portion 222 to rotate the rotating member 20. It should be noted that, since the connecting portion 221 extends from one end of the lock head 21 and extends obliquely upward to the holding portion 222, the connecting portion 221 and the lock head 21 and the holding portion 222 can be regarded as a bending structure, and the bending structure can enhance the structural strength of the entire rotating member 20 to prevent the connecting portion 221 from being broken due to external impact. Further, the holding portion 222 extends vertically from one end of the connecting portion 221, so that a user can conveniently hold the holding portion 222, and further, by applying pressure to one end of the holding portion 222, the lock head 21 is rotated. It is worth mentioning that the distance between the force point of the holding portion 222 and the rotation center of the lock head 21 is increased due to the holding portion 222. In other words, the moment arm is lengthened, so that the force required by the user to rotate the locking head 21 is reduced, so that the user can conveniently rotate the locking head 21 through the holding part 222.

Further, the locking head 21, the connecting portion 221 and the holding portion 222 are integrally formed. It should be noted that the lock 21, the connecting portion 221 and the holding portion 222 are integrally formed to improve the structural strength of the rotating member 20, so as to prevent the rotating member 20 from being cracked and broken due to the structural strength when the rotating member 20 is subjected to external impact.

Specifically, the truck safety lock of the rotating member 20 further has a lock catch 23, the lock catch 23 extends out from one end of the lock head 21, the lock catch 23 has an opening 231 and a cavity 232, the opening 231 is close to the lock head 21, and the opening 231 is communicated with the cavity 232. Further, the cavity 232 is used for accommodating a fixing member 60. When the locking head 21 is rotated by a predetermined angle, the fixing member 60 passes through the opening 231 and is disposed in the cavity 232. Further, when the fixing member 60 contacts the surface of the locking buckle 23 forming the cavity 232, the fixing member 60 restricts the locking head 21 from further rotating. It should be noted that, when the lock head 21 rotates by a preset angle to place the fixing member 60 in the accommodating cavity 232, the box body is locked by the rotating member 20, so that the box body cannot be opened.

Specifically, the base 10 has a mounting hole 101.

Specifically, the base 10 has a ramp 11, and the lock head 21 is rotatably disposed on the ramp 11, wherein the surface of the ramp 11 directly contacts with the bottom surface of the lock head 21, so that the lock head 21 is obliquely disposed on the ramp 11. Since the locking head 21 is obliquely arranged on the sloping platform 11, the locking head 21, the connecting part 221 and the holding part 222 are integrally formed. The rotating member 20 is thus obliquely provided to the ramp 11.

Further, the lock head 21 of the stepped hole 2101 has a stepped hole 2101, wherein the bottom surface of the lock head 21 directly contacts the base 10 so that the axis of the stepped hole 2101 is aligned with the axis of the mounting hole 101.

Specifically, the truck safety lock further comprises a connecting member 30, the connecting member 30 is insertably connected to the mounting hole 101, and the connecting member 30 is also insertably connected to the stepped hole 2101, wherein the lock head 21 is located between the base 10 and the connecting member 30, so that the rotating member 20 and the base 10 are mounted together through the connecting member 30. Further, when the connecting member 30 is inserted into the mounting hole 101 and the stepped hole 2101, the axis of the mounting hole 101, the axis of the connecting member 30, and the axis of the stepped hole 2101 are located on the same straight line. It is worth mentioning that the hole diameter of the mounting hole 101 and the hole diameter of the stepped hole 2101 are larger than the sectional diameter of the link 30 so that the link 30 is slidably inserted into the mounting hole 101 and the stepped hole 2101. Further, when the connection member 30 is inserted through the stepped hole 2101 and into the mounting hole 101, the portion of the connection member 30 inserted into the mounting hole 101 fixes the connection member 30 and the mounting hole 101 together by welding.

Further, a boss 31 extends from one end of the connecting member 30, and the boss 31 is disposed in the mounting hole 101. When the connecting member 30 is inserted through the stepped hole 2101 and into the mounting hole 101, the bottom surface of the boss 31 directly contacts the surface of the stepped hole 2101.

Further, the ramp 11 has an inclined surface 111, and since the bottom surface of the lock head 21 directly contacts the inclined surface 111, when the lock head 21 rotates, friction is generated between the bottom surface of the lock head 21 and the inclined surface 111. If the surface of the inclined surface 111 is rough, a user may generate a large friction force between the locking head 21 and the inclined surface 111 when rotating the rotating member 20, thereby causing difficulty in rotating the rotating member 20. In view of the above, further, the inclined surface 111 is implemented as a smooth surface, and the smooth surface is formed by machining to reduce the friction between the bottom surface of the lock head 21 and the inclined surface 111, so that the user can rotate the rotating member 20 very easily through the smooth surface when rotating the rotating member 20. It should be noted that the conventional rotating member 20 basically horizontally mounts the rotating member 20 on the base 10, and manually applies pressure to one end of the holding portion 222 to rotate the rotating member 20. However, the truck safety lock for locking a container is installed at a high position on the container, so that a user applies an oblique force to the end of the holding portion 222 of the rotating member 20, which causes the opening of the stepped hole 2101 to continuously press the surface of the connecting member 30 when the rotating member 20 rotates, thereby deforming the connecting member 30, and causing the rotating member 20 to be locked and unable to rotate. And the utility model discloses an sloping platform 11 with rotate piece 20 tapered end 21 cooperates, works as tapered end 21 with sloping platform 11 when inclined plane 111 is laminated, rotate piece 20 and installed aslope base 10, and then make the user right again when the portion 222 one end of gripping is exerted pressure, the drill way of stepped hole 2101 can not extrude connecting piece 30 surface.

Specifically, the truck safety lock further includes a limiting member 40, the limiting member 40 is rotatably disposed on the base 10, and the limiting member 40 is located on the same side of the lock head, wherein the limiting member 40 can rotate by a predetermined angle, so that the limiting member 40 rotates to the rotation path of the holding portion 222, and further the rotation of the rotating member 20 is limited, so that the rotating member 20 cannot rotate. When the holding portion 222 of the rotating member 20 is rotated to a position perpendicular to the ground, the fixing member 60 passes through the opening 231, and a surface of the fixing member 60 abuts against a surface of the lock catch 23 forming the cavity 232 to limit further rotation of the lock cylinder 21. Therefore, when the holding portion 222 is perpendicular to the ground, the limiting member 40 is manually pulled to rotate the limiting member 40 onto the rotation path of the holding portion 222, so that the lock head 21 cannot rotate, and the rotating member 20 is limited to a position perpendicular to the ground.

Specifically, the base 10 further has two supporting portions 12 for supporting the limiting member 40, the supporting portions 12 extend from the top surface of the base 10, and the supporting portions 12 are located at the lower right corner of the top surface of the base 10 and close to the rotating member 20.

The use process schematic diagram of the truck safety lock is illustrated in the figures 3 and 4. In the using process, firstly, when a user needs to lock the container, the user manually holds one end of the holding part 222 of the rotating part 20 and applies pressure to one end of the holding part 222, so that the rotating part 20 is forced to rotate. When the grip portion 222 of the rotating member 20 is rotated to be perpendicular to the ground, the fixing member 60 passes through the opening 231 of the lock catch 23, and a surface of the fixing member 60 abuts against a surface of the lock catch 23 forming the cavity 232 to limit further rotation of the rotating member 20. At this time, the user manually pulls the limiting member 40 to rotate the limiting member 40 to the rotation path of the holding portion 222 of the rotating member 20, so that the rotating member 20 cannot rotate, and the holding portion 222 of the rotating member 20 is perpendicular to the ground, so that the truck safety lock locks the box body. When the user needs to open the container, the limiting member 40 is manually pulled first, so that the limiting member 40 no longer blocks the rotation path of the holding portion 222 of the rotation member 20. Then, one end of the holding portion 222 of the rotating member 20 is manually held by a person, and a pulling force is applied to one end of the holding portion 222, thereby rotating the rotating member 20. When the rotating member 20 rotates, the fixing member 60 is disengaged from the receiving cavity 232 and passes through the opening 231. At this point, the user may manually open the container.

In summary, the truck safety lock based on the embodiment of the application is clarified, and the truck safety lock has the advantages of convenience in use, limited limiting function, good safety and the like.

It is worth mentioning that in the embodiment of the present application, the truck safety lock has a simple structure, does not involve a complicated manufacturing process and expensive materials, and has high economical efficiency.
