[0002] With the booming development of the tourism industry and the increasing frequency of business travel, rolling suitcases, as convenient portable tools, are used more frequently. As the core functional component of rolling suitcases, the adjustability of the handle directly determines the user experience.

[0003] When using existing levers, the inclined block on the button usually acts on the slider, which moves the slider to the left and right. However, there may be a problem of asynchronous left and right movement, which reduces the adjustment accuracy and aggravates the wear of local parts. In severe cases, it may even cause the adjustment function to fail. Summary of the Invention

[0004] The purpose of this invention is to provide an easily adjustable suitcase handle that avoids the problem of asynchronous left and right sliding movements, thereby improving the adjustment accuracy of the handle.

[0005] To achieve the above objectives, an easily adjustable trolley handle is provided, comprising a handle body, the handle body including an upper outer shell and a lower outer shell, the upper outer shell being connected to the upper surface of the lower outer shell by screws, a button being provided on the upper inner surface of the middle part of the upper outer shell, and an adjustment component being provided below the button, the adjustment component including two adjustment blocks movably mounted on the inner surface of the lower outer shell.

[0006] According to the aforementioned adjustable trolley handle, the adjustment assembly further includes a support rod rotatably connected to the upper inner surface of the lower outer shell. A gear is fixedly connected to the outer surface of the support rod, and racks are meshed with the front and rear outer surfaces of the gear. Through the arrangement of the gear and rack, when the left rack slides, the right rack slides synchronously, avoiding the problem of asynchronous left and right movement.

[0007] According to the adjustable trolley handle, both racks are fixedly connected to the outer surface of the movable plate, and the movable plate is fixedly connected to the side outer surface of the adjusting block.

[0008] According to the aforementioned adjustable trolley handle, a limiting plate is provided above the gear. The limiting plate is rotatably connected to the upper end of the support rod and is fixedly connected to the upper surface of the lower outer shell by screws. By setting the limiting plate, the axial displacement of the support rod and the gear is restricted, thereby ensuring the stability of the transmission.

[0009] According to the aforementioned adjustable trolley handle, the button is movably connected to the upper inner surface of the upper outer shell, and inclined blocks are fixedly connected to the lower surfaces of both sides of the button. A slider is slidably connected to the outer surface of the inclined block, and the slider is fixedly connected to the outer surface of one side of the adjusting block. The two inclined blocks are arranged symmetrically, and the inclination angle and length of the inclined blocks are the same, ensuring that the force on the sliders on both sides is consistent. By pressing the button, the inclined blocks are moved downward, thereby moving the slider, which in turn moves the adjusting block, thus adjusting the length of the trolley handle.

[0010] According to the aforementioned adjustable trolley handle, a positioning block is fixedly connected to the outer surface of the slider on the side away from the inclined block, and a reset component is fixedly connected to the outer surface of the other side of the positioning block. The reset component includes a telescopic rod and a reset spring, and a reset spring is fixedly connected to the outer surface of the telescopic end of the telescopic rod.

[0011] According to the aforementioned adjustable trolley handle, a fixing plate is fixedly connected to the upper outer surface of the lower outer shell, and a reset member abuts against one side of the outer surface of the fixing plate.

[0012] This utility model has the following beneficial effects:

[0013] 1. Compared with the existing technology, by pressing the button, the left inclined block moves downward with the button, which in turn moves the left slider to the left, which in turn moves the movable plate to the left, which in turn moves the left rack to the left, which further drives the gear to rotate. Then, through the meshing transmission between the gear and the right rack, the right movable plate moves to the right, which in turn drives the right slider and the adjusting block to move to the right. The reverse is also true, thus ensuring that the left and right sliders move synchronously and realizing the adjustment of the rod length. Attached Figure Description

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model discloses an adjustable trolley handle, comprising a handle body 1, an upper outer shell 2, and a lower outer shell 3. The upper outer shell 2 is connected to the upper surface of the lower outer shell 3 by screws, thus fixing the upper outer shell 2 and the lower outer shell 3. A button 4 is provided on the upper inner surface of the middle part of the upper outer shell 2, and an adjustment component 5 is provided below the button 4. The adjustment component 5 includes two adjustment blocks 51 movably mounted on the inner surface of the lower outer shell 3. The adjustment component 5 also includes a support rod 54 rotatably connected to the upper inner surface of the lower outer shell 3. A gear 53 is fixedly connected to the outer surface of the support rod 54, and a limit plate 55 is provided above the gear 53. The support rod 54 rotates through the upper outer surface of the limiting plate 55, and the limiting plate 55 is fixedly connected to the upper surface of the lower housing 3 by screws. The setting of the limiting plate 55 restricts the axial displacement of the support rod 54 and the gear 53, ensuring the stability of the transmission. The front and rear outer surfaces of the gear 53 are meshed with racks 521. Both racks 521 are fixedly connected to the outer surface of the movable plate 52. The movable plate 52 is fixedly connected to the side outer surface of the adjusting block 51. With the setting of the gear 53 and the two racks 521, when the left rack 521 slides, the right rack 521 slides synchronously, avoiding the problem of asynchronous left and right movement.

[0023] Button 4 is movably connected to the upper inner surface of the outer casing 2, and inclined blocks 41 are fixedly connected to the lower surfaces of both sides of button 4. Slider 511 is slidably connected to the outer surface of inclined blocks 41. Slider 511 is fixedly connected to the outer surface of one side of adjusting block 51. The two inclined blocks 41 are arranged symmetrically, and the inclination angle and length of inclined blocks 41 are the same, ensuring that the force on the sliders 511 on both sides is consistent. By pressing button 4, the inclined blocks 41 are moved downward, thereby moving slider 511, thereby moving adjusting block 51, and adjusting the length of the pull rod.

[0024] A positioning block 512 is fixedly connected to the outer surface of the slider 511 away from the inclined block 41. A reset member 32 is fixedly connected to the outer surface of the other side of the positioning block 512. The reset member 32 includes a telescopic rod and a reset spring. A reset spring is fixedly connected to the outer surface of the telescopic end of the telescopic rod. A fixing plate 31 is fixedly connected to the upper outer surface of the lower outer shell 3. The telescopic end of the telescopic rod of the reset member 32 abuts against the outer surface of one side of the fixing plate 31. By driving the slider 511 to move, the positioning block 512 is driven to move, and the reset member 32 is further driven to move towards the fixing plate 31, squeezing the reset spring inside the reset member 32. Then, through the elastic action of the reset spring, the slider 511 and the positioning block 512 are reset.

[0025] Working principle: In use, pressing button 4 moves the left inclined block 41 downwards, causing the left slider 511 to move to the left, which in turn moves the movable plate 52 to the left, causing the left rack 521 to move to the left, further rotating the gear 53. The gear 53 then meshes with the right rack 521, moving the right movable plate 52 to the right, which in turn moves the right slider 511 and adjusting block 51 to the right. The reverse is also true, ensuring that the left and right sliders 511 move synchronously, thus adjusting the length of the lever. Releasing button 4 causes the reset component 32 to spring back under the support of the fixed plate 31, pushing the positioning block 512 and slider 511 to reset synchronously, which in turn moves button 4 and adjusting block 51 back to their initial positions, completing one adjustment cycle.
