Description

Technical Field

[0001] This utility model relates to a trolley, specifically a recessed trolley handle. Background Technology

[0002] In everyday trolleys, the handle is a crucial component, often responsible for operating and controlling the trolley. Traditionally, trolley handles are mostly located on top of the trolley body. While this design is simple, it has some drawbacks. Firstly, traditional handles occupy space on top of the trolley, potentially affecting its aesthetics, ease of use, and storage space. Secondly, exposed handles, their locking mechanisms, and the on / off buttons are susceptible to external impacts, which can lead to unstable handle positioning, locking malfunction, or even damage or misoperation, thus compromising safety and reliability.

[0003] As people's needs for trolley functions diversify and their safety requirements increase, more and more users require trolley designs that are more flexible and have higher safety standards. Especially in logistics, warehousing, and other situations where trolleys are frequently operated, the trolley handles need to have better adjustability and higher stability to ensure stable locking during use and avoid safety hazards caused by accidental operation. Summary of the Invention

[0004] To address the aforementioned issues, this utility model provides a recessed trolley handle. The recessed handle design prevents damage to the locking shaft from impacts by goods, increases the safety of the locking shaft, and also makes better use of the bottom space while reducing the occupancy of the top space.

[0005] This utility model is achieved through the following technical solution: a recessed cart handle, comprising:

[0006] The trolley body has an opening window on one side, and an adjustable plate is movably installed inside the opening window;

[0007] The trolley handle is recessed and hinged to the trolley body. The trolley handle has a locking shaft with two switch buttons. The adjusting plate covers the trolley handle and the locking shaft.

[0008] The trolley handle and the two limit switch lock buttons are stabilized by pressing down the adjustment plate.

[0009] As a preferred technical solution, a locking rod is provided on each of the two sides of the locking shaft, and the switch / lock button is respectively provided on the locking rod. The extension and retraction of the locking rod is controlled by pressing the switch / lock button.

[0010] The trolley body is provided with multiple locking holes, and the locking rod is inserted into the locking holes to achieve the angular position of the trolley handle and the trolley body.

[0011] As a preferred technical solution, a support spring is provided on the opposite surface of the two locking rods, and the two locking rods are pushed out by the support spring.

[0012] As a preferred technical solution, a gap cavity is formed between the two switch lock buttons, and a limiting insert is provided on the lower end face of the adjustment plate corresponding to the position of the gap cavity. When the adjustment plate is adjusted downward along the hinge end, the limiting insert is snapped into the gap cavity.

[0013] As a preferred technical solution, the end of the adjusting plate away from the hinge is the movable end, and a locking groove is provided on the lower end face of the movable end of the adjusting plate. When the adjusting plate is adjusted downward along the hinge end, the locking groove engages with the locking shaft.

[0014] As a preferred technical solution, the bottom surface of the locking groove is an arc-shaped surface, and a rubber contact layer is provided on the inner wall surface of the locking groove.

[0015] As a preferred technical solution, a hinge block is provided at the hinge end of the adjusting plate and the trolley body, a shaft pin is provided through the hinge block, and a locking nut is provided at one end of the adjusting plate.

[0016] The beneficial effects of this utility model are: the handle of this utility model adopts a sunken design and is located at the bottom of the main body of the cart, which can effectively save top space. This is especially important for occasions with limited space or requiring multi-functional use, and avoids the disadvantage of occupying top space in traditional designs.

[0017] Secondly, the adjustment plate can be set to stably lock the position of the trolley handle when it is lowered, avoiding problems such as unstable handle adjustment and locking failure in traditional designs.

[0018] In addition, the adjustment plate protects the locking shaft and the switch / lock buttons from damage or misoperation caused by external impacts, thereby improving the safety of the trolley during use. Especially in high-frequency operation environments, the adjustment plate effectively limits the misoperation of the switch / lock buttons, improving the accuracy and safety of operation. The recessed structure effectively prevents impacts from goods during transportation and effectively prevents damage to the locking shaft, achieving a better locking effect.

[0019] Meanwhile, the adjustable handle of the trolley can be adjusted to change the angle of use according to actual needs, adapting to different work scenarios and increasing the trolley's versatility and applicability. Attached Figure Description

[0027] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0028] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0029] like Figures 1-4 As shown, this utility model provides a sunken cart handle 3. The specific implementation will be described in detail from the following aspects, and the structure and function of each part will be explained in conjunction with the accompanying drawings.

[0030] First, the trolley body 1 of this embodiment is provided with an opening window 5, which is located on one side of the trolley body 1, and an adjustment plate 4 is movably installed inside the opening window 5. The adjustment plate 4, as a structure that can move with the trolley body 1, covers and stabilizes the trolley handle 3 and its locking shaft 13. The recessed hinge design of the trolley handle 3 allows the handle to be placed at the bottom of the trolley body 1 when not in use. This not only saves top space but also avoids the situation in traditional designs where the trolley handle 3 is exposed and easily damaged.

[0031] The trolley handle 3 is hinged to the trolley body 1 via a hinge shaft 8. The trolley handle 3 is locked by a locking shaft 13 connected to the trolley body 1, which has two on / off buttons 2. Each button is connected to a locking rod. Pressing the button controls the extension / retraction of the locking rod, which then inserts into the locking hole 9 of the trolley body 1. The trolley body 1 has a locking plate 10, and the locking holes 9 are located on the locking plate 10. There can be three locking holes 9: one at 0 degrees, one at 90 degrees, and one at 180 degrees. This allows the locking shaft 13 to have three locking positions, enabling adjustment and locking of the handle's angle. In this way, the trolley handle 3 can be adjusted to meet various work requirements, and each adjustment ensures a secure lock, preventing accidental movement during transport.

[0032] To further enhance locking stability, this embodiment also incorporates a support spring. This spring is installed on the opposite surfaces of the two locking rods. Through the action of the support spring, the locking rods can be pushed out, ensuring that they can reliably insert into the locking hole 9 of the trolley body 1, thereby achieving a stronger locking effect. During adjustment, a gap cavity is formed between the lower end face of the adjusting plate 4 and the locking rod. The design of the adjusting plate 4 allows it to be adjusted downwards along the hinge end. When the adjusting plate 4 is pressed down, the limiting insert 12 will engage in the gap cavity, thereby stabilizing the locking shaft 13 and limiting the erroneous operation of the two switch / lock buttons 2.

[0033] In addition, a locking groove 11 is designed on the lower end face of the movable end of the adjusting plate 4. This locking groove 11 is used to cooperate with the locking shaft 13 to ensure that the handle is in a stable position when the adjusting plate 4 is pressed down. The bottom surface of the locking groove 11 is arc-shaped, and the inner wall is covered with a rubber contact layer. This design not only enhances the fitting accuracy between the adjusting plate 4 and the locking shaft 13, but also effectively reduces wear caused by friction and extends service life. Through the contact of the rubber layer, the adjusting plate 4 is more stable during adjustment, avoiding the noise and discomfort caused by direct metal contact.

[0034] Finally, a hinge block 6 is provided at the end where the adjusting plate 4 is hinged to the trolley body 1, and it is fixed by a pivot pin. A locking nut 7 is provided at one end of the pivot pin to ensure the stability of the adjusting plate 4 at the hinge and prevent loosening or instability during adjustment. The cooperation between the pivot pin and the locking nut 7 allows for precise control of the angle of the adjusting plate 4 at the hinge, further improving the adjustment stability and safety of the entire vehicle handle.

[0035] The recessed trolley handle 3 of this embodiment, combined with the above-described structure, not only effectively avoids the safety hazards caused by exposed handles in traditional designs, but also improves the adjustment precision and stability of the trolley handle 3. Its recessed structure saves space, prevents impact from goods during transportation, and protects the switch / lock button 2 via the adjustment plate 4 to prevent accidental operation. Ultimately, this makes the trolley safer and more reliable in practical applications, adaptable to different working environments and usage needs.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
