Description
Technical Field
[0001] This utility model relates to a suitcase handle and belongs to the field of suitcase technology. Background Technology
[0002] A suitcase is a bag or luggage tool used for storing and transporting items. It is typically made of lightweight materials (such as PC, ABS, or aluminum-magnesium alloy) and features multiple internal compartments and straps to optimize space utilization. It is equipped with omnidirectional wheels at the bottom to ensure flexibility and stability during movement. The pull rod, as the core control component of a suitcase, primarily facilitates the user's lifting and moving of the suitcase. It usually consists of a top handle and a retractable pull rod. The pull rod is fixed to the metal frame at the back of the suitcase with screws or rivets to ensure load-bearing capacity and durability. The handle is located at the top of the pull rod and often adopts an ergonomic design, with a surface covered with non-slip soft rubber (such as TPU or rubber) to improve grip comfort. Some high-end models also integrate fingerprint unlocking or USB charging functions, further enhancing practicality.
[0003] Although lever systems are functionally mature, their locking mechanisms still have some significant shortcomings. First, mechanical locking structures (such as spring clips or push-button locking devices) are prone to wear from frequent use or external impacts, leading to insecure locking or jamming, affecting user experience and even posing safety hazards. Second, some locking mechanisms are overly complex, increasing the number of internal components and assembly difficulty, which not only increases the failure rate but also significantly raises maintenance costs. Utility Model Content
[0004] The purpose of this utility model is to provide a luggage handle with a simple, reliable, easy-to-maintain, and low-cost locking mechanism.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows:
[0006] A suitcase handle includes a pull rod and a handle base at the top of the pull rod. The handle base is provided with a handle cover, and a button block is provided between the handle cover and the handle base. The top of the handle cover has a button hole, and the top of the button block has a button located in the button hole. A locking structure is provided on one or both sides of the handle base. The locking structure includes a locking pin groove, which is provided on the handle base. A locking pin is provided in the locking pin groove, and the locking pin slides back and forth along the locking pin groove. An elastic member is provided on the inner side of the locking pin, and the elastic member pushes the head end of the locking pin out of the handle base, so that the head end of the locking pin extends into the locking hole of the suitcase body. The locking pin is provided with an unlocking groove, which has a first unlocking slope. An unlocking pin is provided at the lower part of the button block, and the end of the unlocking pin has a second unlocking slope. The first unlocking slope corresponds to the second unlocking slope.
[0007] When in use, pressing the button causes the unlocking pin to move downwards. The second unlocking ramp of the unlocking pin presses against the first unlocking ramp, causing the locking pin to slide along the locking pin groove, disengaging it from the locking hole and unlocking the button. At this time, the elastic component (such as a spring) is compressed. After the pressure on the button disappears, the elastic component returns to its original state, pushing the locking pin to move back to its original state. At this time, the second unlocking ramp pushes the first unlocking ramp, causing the unlocking pin to move upwards, i.e., the button block moves upwards to reset. The elastic component pushes the head of the locking pin out of the handle seat.
[0008] Of course, an elastic component (such as a spring) can be installed between the button block and the handle base, so that the button can be directly reset upwards under the action of the elastic component after there is no pressure on the button.
[0009] The housing is provided with a handle fixing seat, and the locking hole is provided on the handle fixing seat.
[0010] To guide the up-and-down movement of the button block, the button block is provided with a button guide hole, and a button guide post is provided within the button guide hole. The button block moves up and down between the handle cover and the handle base along the button guide post. Specifically, the button guide post is located at the bottom of the handle cover.
[0011] To prevent the button block from shifting vertically or horizontally, the button guide post includes a left button guide post and a right button guide post. The left button guide post and the right button guide post are located on the left and right sides of the button hole, respectively. The button guide hole includes a left button guide hole and a right button guide hole. The left button guide post is located inside the left button guide hole, and the right button guide post is located inside the right button guide hole.
[0012] Preferably, the locking pin has a main body and a small locking head at the front end of the main body. A locking head hole is provided on the side of the handle base. When the locking pin moves toward the locking head hole, the locking head extends out of the locking head hole. In this way, the main body of the locking pin moves within the locking pin groove, causing the locking head to extend out of the locking head hole, while the main body of the locking pin is confined within the locking pin groove.
[0013] The locking mechanism of this suitcase handle has few internal components, is easy to assemble, simple and reliable, and can reduce maintenance difficulty and cost. Attached Figure Description

[0018] Figure 4 This is a schematic diagram of the handle fixing base structure. Detailed Implementation
[0019] like Figure 1-4 As shown, the luggage handle includes a pull rod 3 and a handle base 4 at the top of the pull rod 3. The handle base 4 is provided with a handle cover 41. A button block 42 is provided between the handle cover 41 and the handle base 4. The button block 42 moves up and down between the handle cover 41 and the handle base 4. A spring (or other type of elastic component) is provided between the button block 42 and the handle base 4. When the button block 42 is pressed, the spring can return it to its original position. The top of the handle cover 41 is provided with a button hole 471. The top of the button block 42 has a button 47, which is located inside the button hole 471. The button block 42 is pressed by pressing the button 47 inside the button hole 471. The spring is located at the bottom of the button 47. One end of the spring is a spring positioning post 472 at the bottom of the button block 42, and the other end of the spring is a spring positioning post 473 on the handle base 4. The spring is confined between the button block 42 and the handle base 4.
[0020] The button block 42 is provided with button guide holes 43, specifically two button guide holes, one on the left and one on the right. A button guide post 431 is provided within each button guide hole 43; that is, the left button guide hole has a left button guide post, and the right button guide hole has a right button guide post. The button guide posts 431 are mounted on the handle cover 41, meaning both the left and right button guide posts are mounted on the handle cover 41. The button block 42 moves along the button guide posts 43 between the handle cover 41 and the handle base 4. The left button guide post is located to the left of the button hole 471, and the right button guide post is located to the right of the button hole 471.
[0021] The handlebar base 4 is provided with a locking structure on one or both sides. For better locking and fixation, the locking structure is provided on both the left and right sides. The locking structure includes a locking pin groove 81, which is provided on the handlebar base 4. A locking pin 8 is provided in the locking pin groove 81. The locking pin 8 slides back and forth along the locking pin groove 81. A spring (or other type of elastic component) is provided at the tail end of the locking pin 8. One end of the spring is the locking pin 8, and the other end is the locking pin groove 81. The spring is confined between the locking pin groove 81 and the locking pin 8. The spring pushes the head end of the locking pin 8 out of the handlebar base 4. After the locking pin 8 extends out of the handlebar base 4, it enters the locking hole 51 of the handlebar fixing seat 5 on the housing, thereby locking the handlebar.
[0022] The locking pin 8 has a main body and a locking head at the front end of the main body. The locking head is relatively small. A locking head hole 84 is provided on the side of the handle base 4. When the locking pin moves toward the locking head hole 84, the locking head extends out of the locking head hole 84. In this way, the main body of the locking pin 8 moves in the locking pin groove 81, driving the locking head in and out of the locking head hole 84. The locking pin groove 81 limits the locking pin 8.
[0023] The upper surface of the locking pin 8 is provided with an unlocking groove 82, the unlocking groove 82 having a first unlocking slope 821. The bottom of the button block 42 is provided with an unlocking pin 45, the bottom end of the unlocking pin 45 having a second unlocking slope 451. The second unlocking slope 451 corresponds to the first unlocking slope 821. When the first unlocking slope 821 moves downward, it can push the second unlocking slope 451 to move inward. Similarly, when the second unlocking slope 451 moves outward, it can push the first unlocking slope 821 to move upward.
[0024] When used on a suitcase, pressing button 47 causes button block 42 to move downward along button guide post 431, and unlocking pin 45 to move downward. The second unlocking ramp 451 presses against the first unlocking ramp 821, pushing locking pin 8 to slide inward along locking pin groove 81. Locking pin 8 (unlocking head) disengages from locking hole 51, thus unlocking the suitcase. At this time, the spring between button block 42 and handle base 4 is compressed, and the spring between locking pin 8 and locking pin groove 81 is also compressed.
[0025] When button 47 is released, the spring between button block 42 and handlebar base 4 returns to its original state, pushing button block 42 upward to reset. Simultaneously, the spring between locking pin 8 and locking pin groove 81 returns to its original state, pushing locking pin 8 to slide outward along locking pin groove 81, pushing the head of locking pin 8 (unlocking head) out of handlebar base 4. Of course, if there is no spring between button block 42 and handlebar base 4, when locking pin 8 slides outward along locking pin groove 81, the first unlocking ramp 821 can push the second unlocking ramp 451 upward, thus pushing button block 42 upward to reset.
[0026] The above embodiments do not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
