Description

Technical Field

[0001] This invention relates to the field of luggage, specifically to a positionable adjustable angle device for a pull rod and a luggage including the positionable adjustable angle device for the pull rod. Background Technology

[0002] In modern society, people often rely on luggage with handles for travel to save time and effort. Existing luggage generally includes vertically pull-out handles that are integrated with the luggage body, and handles with a base on which the luggage is placed. However, regardless of the type, the handle is always perpendicular to the luggage body and cannot be adjusted. This results in uneven force distribution when dragging the luggage, leading to a poor user experience. Summary of the Invention

[0003] The purpose of this invention is to provide a positionable and adjustable angle device for a pull rod, which has a simple structure, can realize multi-angle adjustment of two hinged parts, can be stable and not fall back after adjustment, has convenient reset operation, and is easy to store. It is also a pull rod accessory structure and a bag using this accessory.

[0004] The present invention is achieved through the following technical solution: a positionable and adjustable angle device for a pull rod, comprising a first rotating member and a second rotating member rotatably connected thereto. The first rotating member is fixedly provided with a meshing part, the meshing part having an arc surface with a plurality of tooth grooves, and a rotary member rotatably connected to one side of the meshing part; the second rotating member is rotatably connected with a locking member, the locking member being fixedly provided with a pawl that meshes with the tooth grooves; the second rotating member is also provided with an elastic support member for preventing the pawl from reversing.

[0005] When the engaging part rotates, the pawl moves within the teeth of the engaging part to achieve angle-level adjustment and positioning. Restricted by the elastic support, the pawl can only move in a single direction. When the pawl disengages from the last tooth, the rotating component rotates, causing the locking component to rotate and disengage from the teeth. The first and second rotating components can then rotate relative to each other and reset. After reset, the pawl re-engages with the engaging part through the elastic force of the elastic support, achieving a reset and locking mechanism.

[0006] Furthermore, the elastic support element is an elastic tab, spring, or elastic protrusion.

[0007] Furthermore, the rotating component is provided with a driving part, and the distance from the driving part to the locking part on the side facing the locking part is greater than the distance from the engaging part to the locking part on the side facing the locking part.

[0008] Furthermore, when the drive unit contacts the locking member and drives it to rotate, it uses contact friction, gear meshing, or snap-fit ​​methods.

[0009] Furthermore, the rotating component is also provided with a stop position and an initial position; the included angle between the stop position, the initial position and the rotation axis of the rotating component is adapted to the angle range of the engagement adjustment between the pawl and the meshing part.

[0010] Furthermore, the present invention also includes a limiting part, which is interference connected with the interval position and the initial position, so that the rotatable range of the rotating part is the angle between the interval position, the initial position and the rotation axis of the rotating part.

[0011] Furthermore, one of the first rotating component and the second rotating component is designated as a fixed component, and the other is designated as a moving component.

[0012] Furthermore, the present invention also relates to a trolley bag including the above-mentioned adjustable angle device for the trolley rod. The trolley bag further includes a fixing frame with a through receiving hole, the receiving hole being able to accommodate the above-mentioned adjustable angle device for the trolley rod in its initial or reset state.

[0013] Furthermore, a blocking part is provided inside the receiving hole, and the fixing member is restricted by the blocking part.

[0014] Furthermore, the mounting bracket is installed on the bag body or the bag base frame.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0016] 1. The adjustable angle device for a pull rod of the present invention not only allows for adjustable gear positions, but also ensures stability and prevents the pull rod from falling back after adjustment, and allows for quick reset. It is simple to operate and can be used in multiple parts of pull rod-type luggage products, thereby improving the practicality of using the adjustable angle device.

[0017] 2. This invention relates to a trolley bag with an adjustable angle device, which allows for various angle adjustments between the trolley and the bag, greatly improving user comfort and freedom of use. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example

[0025] like Figure 1-6 As shown, this invention discloses a technical solution for a positionable and adjustable angle device for a pull rod, including a first rotating member 20 and a second rotating member 30 rotatably connected thereto. The first rotating member 20 has a meshing portion 21 fixedly disposed at one end facing the second rotating member 30. The meshing portion 21 has an arc surface with multiple toothed grooves 22. A rotating member 23 is rotatably connected to one side of the meshing portion 21. A locking member 31 is rotatably connected to the second rotating member 30 at one end facing the first rotating member 20. The locking member 31 extends towards the first rotating member 20 and has a pawl 32 that meshes with the meshing portion 21. The second rotating member 30 also has an elastic support member 33 to prevent the pawl 32 from reversing. The meshing portion 21 and the first rotating member 20 can be two separate components fixedly connected, or the two components can be integrated into one unit.

[0026] When the first rotating member 20 and the second rotating member 30 rotate relative to each other, the pawl 32 engages and moves on the teeth of the meshing part 21 to achieve angle-level adjustment and positioning. Its working principle is equivalent to ratchet meshing motion. The elastic support member 33 is placed behind the pawl 32 to restrict the reverse rotation of the pawl 32 and disengage it from the meshing part 21, thereby realizing unidirectional angle adjustment and locking of the first rotating member 20 and the second rotating member 30. When the pawl 32 disengages from the last tooth, the rotating member 23 rotates, causing the locking member 31 to rotate, causing the pawl 32 to disengage from the tooth. The elastic support member 33 is in a deformed state, and the first rotating member 20 and the second rotating member 30 can rotate back to their original positions. During rotation, the rotating member 23 drives the locking member 31 to reset. Through the elastic force of the elastic support member 33, the pawl 32 engages with the initial teeth of the meshing part 21 to achieve reset and locking.

[0027] Specifically, the elastic support member 33 can be an elastic material such as an elastic tab, spring, elastic protrusion, or bump that can provide support for the locking member 31. The elastic support member 33 and the second rotating member 30 can be two separate components fixedly connected together, or the two components can be integrated into one unit. In this embodiment, the elastic tab that integrates the two components is used in the accompanying drawings.

[0028] Specifically, the rotating part 23 is provided with a driving part 24. The closest distance from the end of the driving part 24 facing the locking part 31 to the locking part 31 is greater than the closest distance from the end of the engaging part 21 facing the locking part to the locking part 31, so that when the driving part 24 is linked with the locking part 31, the driving part 24 can push the pawl 32 away from the tooth groove 22. When the driving part 24 contacts the locking part 31 and drives it to rotate, it adopts contact friction, gear meshing, or snap-fit. The contact friction can be any one or a combination of point, line, and surface contact. This embodiment discloses a preferred contact friction driving method. The driving part 24 facing the locking part 31 adopts a multi-segment arc surface connected end to end, with the middle being higher and the two sides being lower. During rotation and reset, the driving part, the locking part, and the pawl on the locking part have a surface contact and a line contact. The contact area is large, the contact is smooth and stable, and the parts are not prone to jumping or collision. The relative rotation process of the first rotating part 20 and the second rotating part 30 is smoothly connected. The overall structure is compact, the user experience is good, the practicality is strong, and the service life of the parts is extended.

[0029] Specifically, the rotating member 23 can only rotate at a certain angle, and its rotation range is determined by the stop position 26 and the initial position 25 on the rotating member 23. Specifically, this embodiment also includes a limiting part 27, which interferes with the stop position 26 and the initial position 25, such that the rotatable range of the rotating member 23 is the angle between the stop position 26, the initial position 25, and the rotation axis of the rotating member 23. In some embodiments, a limiting groove of a certain angle is provided on the meshing part 21 or the first rotating member 20, and a matching protrusion is provided on the rotating member 23; when the rotation range is achieved, the stop position 26 and the initial position 25 are located on opposite sides of the protrusion. This embodiment provides a preferred implementation, in which protrusions are provided on the stop position 26 and the initial position 25 of the rotating member 23, and a protrusion interfering with them is provided on the first rotating member 20. The included angle between the stop position 26, the initial position 25, and the rotation axis of the rotating component 23 engages with the pawl 32 and the meshing part 21 to adjust the relative rotation angle range of the first rotating component 20 and the second rotating component 30. The working principle of this embodiment is as follows: when the first rotating component 20 and the second rotating component 30 rotate relative to each other, the pawl 32 engages and moves on the teeth of the meshing part 21 to achieve angle-level adjustment and positioning. When the pawl 32 runs to the last tooth groove of the meshing part 21 or the stop position 26 of the rotating component 23 abuts against the limiting part 27, the first rotating component 20 and the second rotating component 30 continue to rotate relative to each other. The locking part 31 and the driving part 24 are linked, the pawl 32 leaves the tooth groove 22, and there is no longer any interference between it and the meshing part 21. At this time, the elastic support member 33 is compressed and deformed. The first rotating member 20 and the second rotating member 30 can be reset relative to each other. After reset, the pawl 32 returns to the initial tooth position of the meshing part 21, or when the initial position 25 of the rotating member 23 abuts against the limiting part 27, the first rotating member 20 and the second rotating member 30 continue to rotate relative to each other. The locking part 31 and the driving part 24 are disengaged from the linkage state. Under the elastic action of the elastic support member 33, the pawl 32 re-engages with the meshing part 21, realizing reset and locking, and waiting for the next angle adjustment.

[0030] This embodiment achieves level adjustment and positioning of the rotation angle of the first rotating part 20 relative to the second rotating part 30 through the movement of the teeth of the meshing part 21. The number of tooth slots in the meshing part 21 represents the level of angle adjustment, and the tilt angle is determined by the position of each tooth. Therefore, this embodiment not only enables adjustable tilt angle levels but also locks the levels, thereby improving the practicality of the product using the angle adjustment locking device. The method for resetting the adjustment level is very simple and ingenious, allowing the positioning and adjustment angle structure to be reset to its original level without manual operation, thus facilitating the next round of tilt angle adjustment.

[0031] Specifically, the present invention also relates to a trolley bag with transport rollers comprising the above-described embodiments, wherein a first rotating member 20 and a second rotating member 30 are selected as fixed members, and the other is a moving member; the fixed member is installed in a part of the bag where rotation is not manipulated, and the moving member is installed in a part where rotation is manipulated; the adjustable angle device involved in the present invention can be installed at the junction of the pull rod and the bag body, or at the junction of the pull rod and its extension rod, or even at the junction of the pull rod and the handle, to achieve multi-dimensional adjustment of the trolley bag to adapt to the usage needs of different people when pulling the trolley bag. For example, it can be installed at the junction of the pull rod and the bag body, with the fixed member installed on the bag body, one end of the moving member rotatably connected to the fixed member, and the other end connected to the pull rod, so that the angle of the pull rod relative to the bag body can be adjusted and reset by rotating the pull rod.

[0032] Specifically, the present invention also relates to a trolley bag with transport wheels, comprising the above-described embodiments, including a fixing frame 10, which is mounted on the bag body or a bag base frame. The bag base frame is shaped like a trolley, with wheels mounted at the bottom and the bag body mounted on the upper frame. The pull rod is mounted on one side of the frame, such as in commercially available pet transport bags. The fixing frame 10 has a through-hole accommodating hole 11, which can accommodate the adjustable angle device for the pull rod in the reset state as described in the above embodiments. A blocking part 12 is provided within the accommodating hole 11, and the fixing member is constrained by the blocking part.

[0033] Specifically, one of the first rotating member 20 and the second rotating member 30 is designated as a fixed member, and the other is designated as a moving member. As shown in the accompanying drawings, this embodiment of the invention discloses a positionable and adjustable angle device with a fixed frame 10. The blocking part 12 is an annular stepped platform within the receiving groove 11. The first rotating member 20 is designated as a fixed member. The end of the first rotating member 20 is restricted by the annular stepped platform, and the front end passes through the annular stepped platform and connects to one end of the second rotating member 30. The other end of the second rotating member 30 is connected to the pull rod. When the pull rod, the second rotating member 30, and other linkage components are in the reset state, they conform to the size of the stepped platform and can pass smoothly through the annular stepped platform, and be stored in the back of the bag body or the bottom of the bag rack, saving space and making storage convenient.
