[0032] As Figures 1 to 9As shown in the figure, the present invention relates to a wire-tying controlled luggage case, which includes a case body 1. One side of the case body 1 is provided with a telescopic rod 2, and the telescopic rod 2 is composed of a telescopic rod and a snap fastener. Since this adopts the existing technology, it will not be elaborated here. A number of handles 3 are fixed on the outer periphery of the case body 1. One side of the case body 1 is an opening, and two case covers 4 are arranged on both sides of the opening. The two case covers 4 are movably connected to the case body 1. The movable connection can be fixed by using a movable connecting member, and the movable connecting member can be selected as components such as hinges. In this design, a hinge 9 is adopted. The two case covers 4 are of a split structure, and the two case covers 4 can rotate towards the opening direction until they contact and close. Universal wheels 8 are arranged on the case body 1 and the case covers 4, and the universal wheels 8 play a role in assisting movement. A lock tongue unit 5 is installed at a position close to the side of the case body 1 on the case cover 4. The lock tongue unit 5 includes a fixed block 501. One side of the fixed block 501 is fixed to the case cover 4, and a bent arc-shaped lock tongue curved rod 502 is connected to the side of the fixed block 501 facing the case body 1. A locking unit 6 is provided in the area where the lock tongue unit 5 is close to the case body 1. The locking unit 6 includes a fixed shell 601 fixed to the case body 1. A cavity for the lock tongue curved rod 502 to pass through is opened on the fixed shell 601. A restraint shell 602 is fixed inside the fixed shell 601. Two connecting rods 603 are hinged to the restraint shell 602. The connecting rods 603 are connected with a chuck 604. One side of the chuck 604 is a fan-shaped curved surface, and a semi-circular notch 605 is opened on the other side of the chuck 604. The semi-circular notch 605 can fit with the lock tongue curved rod 502, so that when it is clamped, the constraints on both sides can be increased, and the stability during locking can be improved. An inner cylinder 606 is arranged inside the restraint shell 602. A slider 607 slides inside the inner cylinder 606. The center of one side of the slider 607 is connected with a straight rod 608 passing through the restraint shell 602. Inclined traction plates 609 are hinged between the end of the straight rod 608 and the two connecting rods 603. The two traction plates 609 are symmetrically designed. Through the symmetrical design, the two chucks 604 can be constrained, so that the two chucks 604 open and close synchronously. A pressing spring is arranged on the other side of the slider 607.
[0033] Working principle: When locking is required, move the two case covers 4 to move them to the center. During the process of moving to the closed position, the lock tongue curved rod 502 will pass through the cavity and push against the fan-shaped curved surface on one side of the chuck 604, causing the chuck 604 to open to both sides. At this time, the pressing spring contracts. After insertion, the lock tongue curved rod 502 separates from the fan-shaped curved surface, and the pressing spring returns to its original position, causing the two chucks 604 to close again, and making the semi-circular notch 605 fit with the lock tongue curved rod 502. Thus, automatic locking is achieved during the automatic placement process, reducing the step of manually operating the button, improving the convenience of locking, and solving the problem that the locking process is troublesome and laborious when the luggage is full of items.
[0034] Due to the improved convenience of the above locking, and the need to operate the switches one by one to cancel the locking, the convenience of opening the box will be reduced. In response to this point, a linkage unit 7 for driving the locking unit 6 to open is provided on the box cover 4. The linkage unit 7 includes a housing 701 embedded in the box body 1. Inside the housing 701, a control tie wire 702 is provided. Both ends of the control tie wire 702 are connected with pulling tie wires 703. Two branch tie wires 704 are fixed at the ends of the pulling tie wires 703. The control tie wire 702, the pulling tie wires 703 and the branch tie wires 704 are all routed internally. To protect the tie wires and the box, a wrapping layer can be provided on the outer periphery of the tie wires. The wrapping layer is embedded in the box, and the tie wires are routed internally. The branch tie wire 704 is connected to the slider 607. One end of the control tie wire 702 is slidably limited by the housing 701. The side position of the other end of the control tie wire 702 is connected to the pulling tie wire 703. This end of the pulling tie wire 703 is arranged to bypass the winding post 708. Through the design of winding, when the control tie wire 702 moves, both ends of the pulling tie wires 703 and the branch tie wires 704 are in a state of being pulled and moving.
[0035] To improve safety, a roller password 705 is provided on the housing 701. The roller password 705 is designed to be hollow. A restraint sleeve 706 is installed inside the roller password 705. Convex teeth are provided on the inner wall of the restraint sleeve 706. A plurality of winding posts 708 are installed at one end of the housing 701. A groove is provided in the outer peripheral area of the control tie wire 702 where it is located outside the restraint sleeve 706. The uppermost groove is longer, so as to increase a moving distance. A shifting groove with a straight track is provided at intervals between the plurality of grooves. The shifting groove can fit with the convex teeth. The groove is adapted to the restraint sleeve 706, so that the restraint sleeve 706 can roll on its outer periphery. Combining the cooperation of the shifting groove and the convex teeth, when turning to the required password number, all the convex teeth will be in the position of the shifting groove, which is the unlocking state. A control button 10 is connected to the outer periphery of the control tie wire 702. The control button 10 is slidably limited on the housing 701. Since the distance between the pressing spring and the control tie wire 702 is relatively far, in order to ensure the automatic reset of the control tie wire 702, a restraint ring 709 is provided on the outer periphery of the control tie wire 702 on one side of the spring 707. A spring 707 is provided at one end of the housing 701 away from the winding post 708. The cooperation of the restraint ring 709 and the spring 707 provides elastic force, so that the control button 10 will automatically return to its original position after the box cover 4 is opened.
[0036] Working principle: After turning the password number to make all the convex teeth in the position of the shifting groove to achieve unlocking, then pull the control button 10. The control button 10 pulls the control tie wire 702 to move, driving the pulling tie wires 703 and the branch tie wires 704 at both ends to move, and then synchronously pulling the slider 607 to move, so that the plurality of chucks 604 open synchronously, and moving the box cover 4 can complete opening the box. Thus, the password lock ensures safety, and the linkage of the tie wires realizes the synchronous control of the locking unit 6, making it very convenient to open the box.
[0037] To strengthen the fixation, two intermediate locking structures 11 are provided in the intermediate area between the two lid bodies 4. The intermediate locking structure 11 includes a locking tongue housing 111 fixed to the lid body 4. A sloped locking tongue 112 is tenoned on one side of the locking tongue housing 111. Both sides of the sloped locking tongue 112 are inclined slopes and the bottom is an arc surface. A compression spring 113 is arranged between one end of the sloped locking tongue 112 and the locking tongue housing 111. A locking hook part is arranged on the opposite side of the locking tongue housing 111. Since both sides of the sloped locking tongue 112 are inclined slopes and the bottom is an arc surface, during the process of opening and closing the lid, even if there is an asynchronous deviation, when the slope of the sloped locking tongue 112 is squeezed, it will be subjected to a force. Cooperating with the compression spring 113, it is squeezed into the interior of the locking tongue housing 111 until it pops out after reaching the opening and closing balance for locking, which can avoid running interference during the opening and closing process.
[0038] The locking hook part includes a locking hook housing 114. A rotatable circular shell 115 is arranged inside the locking hook housing 114. A central shaft 116 fixed to the locking hook housing 114 penetrates through the center of the circular shell 115. A torsion spring 117 is connected between the central shaft 116 and the circular shell 115 in a way of snap-fit and bonding. A curved arc locking hook 118 is connected to the outer periphery of the circular shell 115. A recessed part adapted to the curved arc locking hook 118 is opened at the bottom of the sloped locking tongue 112. An auxiliary tie line 119 connected to the pulling tie line 703 is eccentrically connected to the outside of the circular shell 115. Two winding rods are provided at the end where the auxiliary tie line 119 passes through. Through the design of the curved arc locking hook 118, when inserting into the sloped locking tongue 112, the curved arc locking hook 118 will be squeezed by the arc surface at the bottom of the sloped locking tongue 112 and rotate downward. At this time, the circular shell 115 is driven to rotate, and the torsion spring 117 is bent under force. When in the locking position, the torsion spring 117 returns to its original position under the action of the elastic force, and then the recess at the bottom of the sloped locking tongue 112 can be hooked to achieve fixation. It is worth introducing that since the provided auxiliary tie line 119 is connected to the pulling tie line 703, when unlocking further, it is also controlled by a single switch, ensuring convenience.
