Description

Technical Field

[0001] The utility model relates to the technical field of pickup truck rear compartment tray locks, in particular to a tray handle lock. Background Art

[0002] A pickup truck is a small truck with a small cargo box. To facilitate loading and unloading of cargo, a sliding pallet is sometimes installed in the pickup truck cargo box, and a pallet lock is used to secure the pallet to the truck bed.

[0003] The Chinese patent with the patent number 202420053930.2, entitled Aluminum Pallet for Pickup Trucks, discloses a locking device between a pallet and a vehicle compartment. The pallet lock drives the locking mechanism on both sides of the pallet through a pull rope, and the pull rope is passed through a drawstring, which is used to unlock the locking mechanism. When the pallet needs to be pulled out, the drawstring is pulled, which drives the pull rope at the same time to unlock the locking mechanism, and then the force is increased to drag the pallet out of the vehicle compartment through the drawstring and the pull rope. The draw rope is generally made of steel wire rope. When the items placed on the pallet are heavy, a large pulling force is required to drag the pallet out. Since the draw rope is passed through the drawstring, part of the pulling force will be transferred to the draw rope. The draw rope becomes loose during the repeated pulling process, which will seriously affect the flexibility when unlocking and the feel when using it. At the same time, the large pulling force acting on the draw rope will also cause the spring in the locking mechanism to fatigue and fail. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a pallet handle lock in view of the above-mentioned deficiencies in the prior art, which has a good hand feel when unlocking the pallet and does not cause the pull rope to become loose, thereby affecting the unlocking flexibility.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a pallet handle lock, comprising a bracket, a handle, a pull rope and a locking mechanism. The handle is rotatably connected to the bracket through a rotating shaft, and the pull rope is connected or engaged with one end of the handle. When the handle is rotated, the pull rope is tightened to unlock the locking mechanism. It also includes a limiting part for limiting the rotation angle of the handle. When the handle is rotated to the unlocking angle, it conflicts with the limiting part.

[0006] With the above technical solution, during use, the locking mechanism is installed at both ends of the tray, the bracket is installed in the middle of the tray, and the drawstring is connected to or snapped onto the handle. When the handle is rotated, it rotates around the rotating shaft, thereby tightening the drawstring and unlocking the locking mechanism. At the same time, the limiter can limit the rotation angle of the handle. By limiting the rotation angle of the handle, the tightening distance of the drawstring is controlled so that this distance meets the unlocking requirements of the locking mechanism. When the handle is rotated to the unlocking angle to unlock the locking mechanism, the end of the handle and the limiter contact the limiter, and the force of the handle pulling the tray out is not transmitted to the drawstring, thereby preventing the drawstring from being subjected to excessive tension and becoming loose, which affects the flexibility and accuracy of unlocking. When the handle is released, the drawstring is reset by the spring within the locking mechanism.

[0007] As a further solution: the handle is L-shaped, including a gripping section and a resistance section, and the rotating shaft is arranged at the connection between the gripping section and the resistance section.

[0008] Through the above technical solution, when the grip section is pulled, the entire handle can be smoothly driven to rotate, and the hand feel is better when used.

[0009] As a further solution: a slot is provided on the interference section, and the pull rope is passed through the slot.

[0010] With this technical solution, when the handle rotates, the interference section drives the drawstring to move in the direction of the interference section, tightening the drawstring and unlocking the locking mechanism. Furthermore, there is no need for a fixed connection between the drawstring and the handle, making it more convenient to replace the drawstring.

[0011] As a further solution, the bracket is provided with two supporting arms, the handle is rotatably connected between the two supporting arms, and the limiting portion is provided on the upper side of the supporting arms.

[0012] Through the above technical solution: the overall structure is relatively compact and the handle can be fixed relatively stably.

[0013] As a further solution: a return spring is connected between the limiting portion and the gripping section.

[0014] Through the above technical solution, the setting of the reset spring can facilitate the reset of the handle, avoiding relying solely on the spring inside the locking mechanism for reset during long-term use, which causes fatigue of the spring inside the locking mechanism and weakened rebound ability.

[0015] As a further solution: a drawstring hole is provided on the support arm, and the drawstring is passed through the drawstring hole.

[0016] Through the above technical solution, the position of the pull rope on the outside of the support arm can be restricted, and the position of the pull rope will only change in a small section between the two arms, thereby preventing the pull rope from being clamped or bounced against a part of the body or other objects during use.

[0017] As a further solution: the gripping section and the interference section are perpendicular, and the gripping section is longer than the interference section.

[0018] Through the above technical solution, the pulling force required to unlock the locking mechanism is reduced. On the premise of realizing the tray locking function, there is no obvious unlocking feeling when unlocking, which provides a better operating experience and feel.

[0019] As a further solution: a spring hanging hole is provided on the limiting portion, and a spring hanging groove is provided on the gripping section.

[0020] Compared with the prior art, the beneficial effect of the present invention is that the rotation angle of the handle is limited by the limit part, so that the pull rope is only subjected to the tension when the locking mechanism is unlocked, and the force for dragging the tray out of the car is completely transmitted to the tray by the handle through the bracket, thereby avoiding the pull rope from being subjected to a large tension and becoming loose, ensuring a better operating feel.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figure 1-4 As shown, a pallet handle lock is used to be installed on a pallet 14 in the cargo box of a pickup truck. The cargo box of the pickup truck is generally equipped with guide rails 15, and the pallet 14 is installed in the guide rails 15 and can slide along the guide rails 15. The pallet handle lock is installed on the rear edge of the pallet 14 to lock the position of the pallet 14.

[0030] The pallet handle lock comprises a bracket 1, a handle 2, a pull cord 3, and a locking mechanism 4. The locking mechanism 4 is mounted on the rear edge of the tray 14. The pull cord 3 connects the locking mechanism 4 to the handle 2 and unlocks the handle 2 under its control. The locking mechanism 4 is conventional and includes a retractable locking tongue and a spring. Initially, the tongue extends under the action of the spring. When the pull cord 3 is tightened, the tongue retracts under the action of the spring, overcoming the spring force. When the pull cord 3 is released, the tongue extends again under the action of the spring.

[0031] like Figure 5 As shown, the bracket 1 is U-shaped as a whole and includes two arms 10. The handle 2 is rotatably connected between the two arms 10 via a rotating shaft 5, and the handle 2 as a whole can rotate around the rotating shaft 5. The bracket 1 is also provided with a limit portion 6, which is arranged on the upper side of the two arms 10.

[0032] like Figure 6 As shown, the handle 2 is L-shaped and includes a gripping section 7 and an abutting section 8 that are perpendicular to each other. The rotating shaft 5 is disposed at the connection between the gripping section 7 and the abutting section 8. When the gripping section 7 is pulled from the initial position, the handle 2 can rotate to a certain angle, and then the abutting section 8 and the lower surface of the limiter 6 come into contact, thereby limiting the rotation angle of the handle.

[0033] The support arm 10 is provided with a hole for the drawstring 3, and the drawstring 3 is inserted into the hole. The interference section 8 is provided with a slot 9. When the handle is in the initial position, the drawstring 3 hole is opposite the slot 9, and the drawstring 3 is inserted into the drawstring 3 hole and the slot 9. When the handle is pulled to unlock the locking mechanism 4, the handle rotates clockwise as a whole, and the drawstring 3 engaged in the slot 9 bends clockwise along with the interference section 8, thereby tightening the drawstring 3 as a whole and driving the locking mechanism 4 to unlock. When the handle is rotated to the unlocking angle and the locking mechanism 4 is unlocked, the interference section 8 of the handle contacts the limiter 6, which restricts further rotation of the handle. At this time, the pulling force applied to the handle is directly transmitted to the tray 14 through the bracket 1, causing the tray 14 to move backward along the guide rail 15, thereby sliding the tray 14 and the items placed on the tray 14 out of the cargo box for easy transportation or use.

[0034] The length of the gripping section 7 is greater than that of the interference section 8, thereby reducing the pulling force required to unlock the locking mechanism 4. On the premise of realizing the locking function of the tray 14, there is no obvious unlocking feeling when unlocking, which has a better operating experience and feel.

[0035] A return spring (not shown) is connected between the stopper 6 and the gripping section 7. The stopper 6 is provided with a spring hanging hole 12, and the gripping section 7 is provided with a spring hanging slot 13. One end of the return spring hangs in the spring hanging hole 12, and the other end hangs in the spring hanging slot 13. The return spring provides additional restoring force, allowing the handle 2 to return to its original position more quickly when it is released.

[0036] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
