DETAILED DESCRIPTION

[0030] The embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application. In the description of the present application, it should be understood that the terms "upper", "lower", "front", "upper surface" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0031] Please refer to Figures 1-13 The present application provides an embodiment: a roller shutter device for a pickup truck box, comprising a first guide seat 1 mounted on one side of the truck bed, a second guide seat 2 mounted on the other side of the truck bed, and a roller shutter 4 arranged between the first guide seat 1 and the second guide seat 2; a locking mechanism 3 is further arranged between the first guide seat 1 and the second guide seat 2, and the locking mechanism 3 controls the unfolding of the roller shutter 4 and the locking of the position after unfolding; the locking mechanism 3 comprises a crossbeam 30 transversely arranged between the first guide seat 1 and the second guide seat 2, and the crossbeam 30 is provided with a locking piece 31 at both ends; the locking piece 31 comprises a mounting frame 317 mounted on the end of the crossbeam 30, and the mounting frame 317 is further provided with a lock tongue 319; the lock tongue 319 located on both sides of the crossbeam 30 abuts on the first guide seat 1 and the second guide seat 2 respectively, so as to prevent the crossbeam 30 from sliding between the first guide seat 1 and the second guide seat 2.

[0032] In summary, when the two locking tongues 319 are abutted in the corresponding guide seats, the locking mechanism 3 can be fixed between the two guide seats, and the locking mechanism 3 is linked with the roller shutter 4, so that the continued rolling of the roller shutter 4 can be prevented by the locking mechanism 3 to adjust the coverage range of the roller shutter 4 to the container.

[0033] Specifically, the middle part of the cross beam 30 is provided with a lock 32; the lock 32 comprises a lock shell 36, a first pulling member 37 and a second pulling member 38 rotatably installed in the lock shell 36; and the first pulling member 37 and the second pulling member 38 are caused to move away from each other by a linkage member 39 provided in the lock shell 36; the locking tongue 319 on one side of the cross beam 30 is connected with the first pulling member 37 through a steel wire rope, and the locking tongue 319 on the other side of the cross beam is also connected with the second pulling member 38 through a steel wire rope. Therefore, the rotation of the linkage member 39 in the lock shell 36 can cause the two pulling members to move away from each other, and then cause the locking tongue 319 to retract into the mounting frame 317.

[0034] Further, the spring 318 is provided between the locking tongue 319 and the mounting frame 317, and the spring 318 is sleeved outside the steel wire rope and is used to cause the locking tongue 319 to extend outwardly of the mounting frame 317 after the external force disappears. Therefore, when the external force driving the rotation of the linkage member 39 disappears, the spring 318 resets, causes the corresponding locking tongue 319 to extend outwardly, and also drives the two pulling members to move towards each other, so as to reset the first pulling member 37, the second pulling member 38 and the linkage member 39.

[0035] In addition, the linkage member 39 causes the first pulling member 37 to rotate through the first abutting portion 314, and the linkage member 39 causes the second pulling member 38 to rotate through the second abutting portion 315. Therefore, the two abutting portions are in contact with the corresponding pulling members, so that the linkage member 39 can reliably push the two pulling members away, to ensure the reliable linkage between the two pulling members and the linkage member 39.

[0036] On the basis of the above-mentioned scheme, the lock shell 36 is provided with a support frame 311, and a hook assembly 310 is rotatably installed on the support frame 311; the hook assembly 310 comprises a linkage seat 328 and a hook 327, and the hook 327 is rotatably installed on the linkage seat 328 through the shaft pin 324 provided thereon, one side of the lock shell 36 is also provided with a press lock 322, and the bottom surface of the press lock 322 is in contact with the contact surface 325 provided on the linkage seat 328.

[0037] Therefore, when the press lock 322 is unlocked, the lock core of the press lock 322 is pressed downward until the lock core is in contact with the contact surface 325, and as the pressing continues, the lock core can drive the linkage seat 328 to rotate, thereby driving the hook 327 to disengage from the lock catch on the rear wall of the cargo box, and the unlocking action of the lock 32 is completed. Based on this, when the roller shutter 4 covers the cargo box, the press lock 322 can be used to improve the anti-theft capability of the device. The press lock 322 is a prior art, and therefore will not be described here.

[0038] Further, since the end of the hook 327 away from the shaft pin 324 passes through the cross beam 30 and is exposed outside the cross beam 30, the hook 327 can be hooked on the lock catch provided on the tail plate of the cargo box. In addition, since the cross beam 30 is also provided with a buffer block 34, and the buffer block 34 is symmetrically arranged on both sides of the hook 327, the buffer block 34 can also be used to protect the hook to avoid the problem that the hook 327 is deformed or damaged by the direct impact of the locking mechanism 3 on the tail plate of the cargo box. The material of the buffer block 34 is preferably rubber material.

[0039] Further, in order to realize the automatic reset of each component inside the locking mechanism 3, the linkage 39 is also provided with a rear reset pin 316. One end of the rear reset pin 316 passes through the cross beam 30 and is exposed outside the cross beam 30, and the other end of the rear reset pin 316 is in contact with the stress part 326 provided on the linkage seat 328 through the provided protrusion 323, and the stress part 326 is pushed by the protrusion 323 to drive the hook 327 to rotate on the shaft pin 324.

[0040] In summary, when the rear reset pin 316 is driven by external force or is in contact with the tail plate of the cargo box, the rear reset pin 316 drives the linkage 39 to rotate in the lock shell 36, thereby driving each part in the lock shell 36 to automatically reset.

[0041] In order to ensure that the locking mechanism 3 can also be opened in an emergency, the cross beam 30 is also provided with an emergency reset key 35, and the linkage 39 is driven to rotate in the lock shell 36 by the emergency reset key 35. Therefore, the emergency reset key 35 can also drive the linkage 39 to rotate in the lock shell 36, thereby completing the unlocking action of the locking mechanism 3.

[0042] Further, the emergency reset key 35 is connected with the notch 312 of the linkage 39 through the provided toggle pin 320. In specific use, usually a rope is tied to one end of the emergency reset key 35, and the rope is pulled to rotate the emergency reset key 35, at this time, the toggle pin 320 clamped in the notch 312 drives the linkage 39 to rotate, and then the unlocking action of the locking mechanism 3 is completed through the emergency reset key 35. In addition, in order to ensure the reliable work of the emergency reset key 35, the shaft is connected with the cross beam 30 after passing through the shaft pin hole 321, so that the emergency reset key 35 rotates along the shaft.

[0043] Further, since the front reset pin 33 is further provided on the cross beam 30, and one end of the front reset pin 33 passes through the back of the cross beam 30 and faces the baffle 313 provided on the linkage 39, therefore, the user can press the front reset pin 33 at any time to make the locking tongue 319 abut against the corresponding guide seat, so as to realize the adjustment of the opening size of the roller shutter 4 at any time.

[0044] The above describes the embodiments of the present application in detail in combination with the drawings, but the present application is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the present application, and still fall within the protection scope of the present application.
