Description

Technical Field

[0001] This invention relates to a pickup truck accessory, and more particularly to a locking structure for a pickup truck bed cover. Background Technology

[0002] Pickup truck beds are typically used for transporting goods, and since there's no roof covering, cargo is easily exposed to rain or strong winds. Therefore, pickup truck bed covers have emerged on the market to cover the cargo bed. These covers are usually fixed around the perimeter of the bed and covered with leather in the center. However, standard pickup truck bed covers are often rigidly fixed, requiring the entire cover to be removed and installed, which is very time-consuming.

[0003] Currently, US Patent Application No. US10500934B1 discloses a locking structure and a pickup truck hood including the locking structure. The locking structure and the pickup truck hood including the locking structure include a control box, a sliding handle, and a cable member via a sliding box assembly. The sliding handle is slidably mounted in the control box along a direction perpendicular to the longitudinal direction of the locking frame. The two ends of the cable member are respectively connected to the locking members of the two locking box assemblies, and the cable member abuts against the sliding handle. When the locking frame is installed at the end portions of the two fixed side frames, at least one reset member can push the latch to be clamped into the locking groove, and the sliding handle can drive the cable member to disengage the latch from the locking groove. However, this method of driving the cable member by pulling the sliding handle is prone to damage, making operation inconvenient and the structure complex. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to address the shortcomings of the prior art.

[0005] A locking structure for a pickup truck bed cover is provided.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a locking structure for a pickup truck bed cover, comprising two fixed side frames and a locking frame. The inner wall of the fixed side frame is provided with a locking groove. A positioning seat is provided at one end of the locking groove near the locking frame. A positioning clamping groove is provided at one end of the positioning seat facing the locking frame. The locking frame includes a horizontal frame body and two connectors respectively installed at both ends of the horizontal frame body. The connectors are connected to the fixed side frames. A locking box is provided at one end of the connector facing the positioning seat. The other end of the locking box is movably connected to the positioning clamping groove. The locking box is characterized in that: a locking element and a reset element are provided inside the locking box. The reset element is connected to the locking element. A first button and a second button are provided on the locking box. When the first button abuts against the locking groove, the reset element causes the locking element to pop out, and the second button protrudes outward. When the second button protrudes, pressing the second button causes the locking element to retract, causing the locking box to spring open upward.

[0007] Using the above technical solution, the initial state of the present invention is the retracted state. When the horizontal frame is installed on the end of the fixed side frame, the first button abuts against the locking groove. Under the action of the reset member, the locking member will pop out and insert into the locking groove of the fixed side frame to lock the locking structure. At this time, the second button will protrude outward. When the second button protrudes, pressing the second button will automatically cause the locking member to retract, causing the locking box to pop up. This structure is convenient to operate, simple in structure, and not easily damaged.

[0008] A further provision of the above technical solution is as follows: the locking box includes a limiting groove and a locking cover plate covering the limiting groove. The limiting groove has mounting grooves at both ends for placing locking components. The mounting groove has a first opening adapted to the locking component at one end facing the locking groove, and a third opening adapted to the second button at the other end. The second button has a sliding groove at one end facing the locking cover plate. A second opening adapted to the first button is provided between the first opening and the third opening. The position of the second opening is parallel to the position of the locking groove.

[0009] By adopting the above technical solution, the mounting groove can prevent the locking component from damaging the locking box. By making the position of the second opening parallel to the position of the locking groove, when the horizontal frame is installed on the end of the fixed side frame, the first button abuts against the locking groove, which is convenient to operate and has a simple structure.

[0010] A further configuration of the above technical solution is as follows: the first button includes a placement groove, a locking spring is provided in the placement groove, and outwardly extending convex plates are provided at both ends of the placement groove. The length of the convex plates is greater than that of the first opening. A positioning slide groove is provided in the placement groove toward the first opening, and a slider adapted to the positioning slide groove is provided in the second opening.

[0011] By adopting the above technical solution, the outwardly extending convex plates at both ends of the placement groove can better prevent the locking structure from popping out.

[0012] A further provision of the above technical solution is that: the locking cover plate is provided with a fixing block for fixing the placement groove and a movable block adapted to the sliding groove at one end facing the limiting groove, and the fixing block and the movable block are parallel.

[0013] By adopting the above technical solution, the reset component can be better fixed by the fixing block, and the movable block adapted to the sliding groove can further limit the second button from being damaged.

[0014] A further provision of the above technical solution is that: one end of the locking member is provided with a locking tongue, and the other end is provided with a spring groove for connecting the reset member, and the reset member is connected to the other end of the locking member and abuts against the locking box.

[0015] By adopting the above technical solution, by having one end of the reset component abut against the locking box, the locking component can be better ejected and inserted into the locking groove of the fixed side frame.

[0016] A further configuration of the above technical solution is as follows: the spring groove is provided with a boss extending toward the third opening, the boss is provided with an upwardly extending protrusion, the boss is provided with a limiting member, one end of the protrusion facing the first opening abuts against one end of the limiting member, the other end of the limiting member abuts against the second button, the limiting member is provided with a limiting hole, and the limiting groove is provided with a movable member for connecting the limiting hole.

[0017] Using the above technical solution, when the horizontal frame is installed on the end of the fixed side frame, the first button abuts against the locking groove and moves towards the limiting groove. The boss on the locking member moves under the convex plate and engages with it. The locking tongue of the locking member pops out through the reset member and inserts into the locking groove of the fixed side frame to lock the locking structure. At this time, the second button will protrude outward. Pressing the protruding second button will push the limiting member inward by the second button. The end of the protrusion facing the first opening abuts against one end of the limiting member, and the other end of the limiting member abuts against the second button. The limiting member will drive the locking member to retract inward, causing the locking box to pop open upward. This method is convenient to operate, simple in structure, and not easily damaged.

[0018] A further setting of the above technical solution is that the second button is T-shaped.

[0019] By adopting the above technical solution, the T-shaped shape of the second button can better facilitate the retraction of the locking component.

[0020] The beneficial effects achieved by this invention are as follows: when the horizontal frame is installed on the end of the fixed side frame, the locking member will be pushed out and inserted into the locking groove of the fixed side frame by the action of the first button against the locking groove under the action of the reset member, so as to lock the locking structure. At this time, the second button will protrude outward. When the second button protrudes, pressing the second button will automatically cause the locking member's locking tongue to retract, so that the locking box will pop up. This structure is convenient to operate, simple in structure, and not easily damaged. Attached Figure Description
