Description

Technical Field

[0001] This utility model relates to the field of luggage handle technology, specifically a luggage handle structure. Background Technology

[0002] Suitcases are a common tool for people to travel, allowing them to store their personal belongings for carrying and transport.

[0003] Currently, most mainstream suitcases on the market (including rolling suitcases, carry-on suitcases, and other types of suitcases with handles) only have the core functions of length adjustment and gripping and pulling. However, if small items are carried by an additional hand, it will occupy one of the user's hands (or hold the handle and small items at the same time with one hand), which will increase the burden on the user's hand. This is especially inconvenient when other tasks need to be handled at the same time (such as showing tickets, opening doors, using mobile phones, etc.), and may even cause small items to slip and be damaged due to uneven force on the hand.

[0004] In light of this, we have introduced a luggage handle structure. Utility Model Content

[0005] The purpose of this utility model is to provide a luggage handle structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a luggage handle structure, comprising: a sleeve and a top mount;

[0007] One end of the sleeve is provided with a pull rod tube, and the inside of the pull rod tube is provided with a telescopic tube. One end of the telescopic tube is connected to a handle assembly, which is used by the operator to hold it.

[0008] The top seat is mounted on the surface of the sleeve, and the surface of the top seat is provided with a positioning pin A;

[0009] The handle assembly includes a grip connected to one side of a telescopic tube, a hook on the inside of the grip, and a hook groove on the surface of the hook.

[0010] A screw is provided between the grip and the telescopic tube. The screw passes through the side wall of the grip and is threaded to the end of the telescopic tube. The screw fastens the grip and the telescopic tube to achieve a stable connection. At the same time, the threaded connection makes it easy to disassemble, repair or replace the grip later, reducing maintenance costs.

[0011] Preferably, the top seat is provided with a positioning post B on its side for positioning. Positioning post B and positioning post A are symmetrically distributed and together constitute the bidirectional positioning structure of the top seat. When the pull rod is assembled with the housing, positioning post B and positioning post A are respectively inserted into the corresponding positioning holes of the housing to limit the top seat and sleeve from different directions, further enhancing the stability of the pull rod after installation and preventing the pull rod from twisting or displacing due to uneven force during use.

[0012] Preferably, the telescopic tube has an elastic telescopic column inside, and the surface of the tie rod tube has through slots at equal intervals for passing through the elastic telescopic column.

[0013] Preferably, the surface of the grip is provided with an arc-shaped part, which conforms to the curvature of the palm when the human hand holds it, thereby increasing the contact area between the grip and the palm, dispersing hand pressure, and avoiding hand soreness caused by prolonged holding.

[0014] Preferably, the surface of the grip is provided with a button for adjusting the length of the telescopic tube. The button is linked to the elastic telescopic column inside the telescopic tube through a linkage structure. When the button is pressed, the linkage will drive the elastic telescopic column to compress the spring, causing the column to retract from the through groove of the pull rod tube, releasing the locked state of the telescopic tube. At this time, the user can freely pull or push the telescopic tube as needed. After adjusting to the appropriate length, the button is released, and the elastic telescopic column will automatically lock into the corresponding through groove, completing the length locking. The entire adjustment process does not require additional tools and is simple and quick to operate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The design of hooks and hook slots adds the function of carrying small items to the suitcase, so that there is no need to carry them by hand or put them inside the suitcase. It is especially suitable for carrying frequently used items such as personal clothing bags and thermos cup straps, which improves the suitcase's adaptability to various usage scenarios.

[0017] (2) The curved part of the handle surface is designed strictly according to the contour of the human hand, which increases the contact area between the hand and the handle when holding it, disperses the pressure of the pulling force on the local skin of the hand, and significantly reduces hand fatigue after pulling the suitcase for a long time; at the same time, the curved part can improve the grip friction, and even when the hands are sweaty or carrying items, it can ensure that the handle does not slip, thus improving the safety of use.

[0018] (3) Through the linkage design of the button and the elastic telescopic column, the length of the pull rod can be adjusted with one click. The entire adjustment process does not require any additional tools and can be completed with one hand to press, stretch / compress and release the lock. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] Please see Figure 1-5 The present invention provides a technical solution: a luggage pull rod structure, including: a sleeve 13, a pull rod tube 8 is provided at one end of the sleeve 13, a telescopic tube 6 is provided inside the pull rod tube 8, and a handle assembly 1 is connected to one end of the telescopic tube 6 for the operator to hold;

[0028] Top seat 10 is disposed on the surface of sleeve 13, and positioning post A11 is provided on the surface of top seat 10;

[0029] The handle assembly 1 includes an ergonomically designed grip 15 that is adapted to the end of the telescopic tube 6 (a screw 5 is provided between the grip 15 and the telescopic tube 6 to achieve rigid fixation between the two and prevent relative loosening). The inner side of the grip 15 faces the side of the suitcase body and is provided with a hook 3 for hanging small items by means of a buckle. The surface of the hook 3 is recessed along its length to form a hook groove 4 for limiting the hanging strap of the item and preventing it from slipping.

[0030] A screw 5 made of stainless steel is provided between the grip 15 and the telescopic tube 6, which runs through both in a direction perpendicular to the axis of the telescopic tube.

[0031] The side of the top seat 10 extends horizontally and is integrally formed with the top seat 10. It is provided with a positioning post A11 for positioning to achieve bidirectional positioning and a positioning post B12 to prevent the sleeve 13 from rotating.

[0032] The telescopic tube 6 has an elastic telescopic column 7 with elastic reset function installed inside the tube near the tie rod tube and in the radial direction. The surface of the tie rod tube 8 has through slots 9 that are evenly distributed at the same distance along its axial direction to pass through the elastic telescopic column 7, thereby locking the length of the telescopic tube and matching the diameter of the slots with the elastic telescopic column.

[0033] The surface of the grip 15 conforms to the contour of the human hand, and the outward arc-shaped protrusion is provided with an arc-shaped part 14 to improve grip comfort and friction.

[0034] The surface of the grip 15 is close to the area where the operator's fingers hold it and is linked to the elastic telescopic column. It is equipped with a button 2 for adjusting the length of the telescopic tube 6, which controls the extension and retraction of the elastic telescopic column and realizes the adjustment of the length of the pull rod.

[0035] Specifically, when using the device, if the operator needs to adjust the length of the lever to suit different heights or usage scenarios, first hold the handle 15. At this time, the fingers can naturally fit the arc-shaped part 14 on the surface of the handle (the arc-shaped part 14 is ergonomically designed to improve grip stability and reduce hand fatigue). Then press the button 2 on the surface of the handle 15. The button 2 and the elastic telescopic column 7 inside the telescopic tube 6 form a linkage structure. The pressing action will generate axial pressure on the elastic telescopic column 7, forcing the elastic telescopic column 7 to compress and retract into the telescopic tube 6, releasing its restriction on the lever tube 8.

[0036] After the elastic telescopic column 7 is retracted, the fixed relationship between the telescopic tube 6 and the pull rod tube 8 is broken. The operator can pull up or press down the handle 15 as needed to drive the telescopic tube 6 to slide axially inside the pull rod tube 8. Since the surface of the pull rod tube 8 is provided with through grooves 9 at equal intervals, the operator can observe the length of the telescopic tube 6 and select the appropriate position of the through groove 9 to meet the usage needs (for example, taller users can pull the telescopic tube 6 out a longer distance, while shorter users can shorten the length of the pull rod).

[0037] When the telescopic tube 6 is adjusted to the target length, release button 2. At this time, the elastic telescopic column 7 is no longer compressed by external force and resets under its own elastic force. One end of it passes through the corresponding through groove 9 on the surface of the pull rod tube 8 and extends to the outside of the pull rod tube 8, forming a mechanical locking structure. This locking structure can effectively limit the relative sliding between the telescopic tube 6 and the pull rod tube 8, ensuring that the pull rod maintains a stable length during use and avoiding the impact on safety due to accidental sliding.

[0038] The cooperation between the top seat 10 and the positioning post achieves a stable connection between the pull rod structure and the suitcase body. The specific working process is as follows: When the pull rod structure is installed on the suitcase body, the sleeve 13 is first aligned with the preset installation position of the suitcase body. At this time, the top seat 10 on the surface of the sleeve 13 plays a reference positioning role. The positioning post A11 on the surface of the top seat 10 is perpendicular to the surface of the top seat and can be inserted into the positioning hole at the corresponding position of the suitcase body, initially restricting the horizontal displacement of the sleeve 13 on the surface of the suitcase body. At the same time, the positioning post B12 on the side of the top seat 10 extends horizontally and is inserted into the positioning groove on the side of the suitcase body, further restricting the vertical displacement and rotation tendency of the sleeve 13, realizing the bidirectional pre-positioning of the pull rod structure.

[0039] After pre-positioning, the top seat 10 is fastened to the box body with bolts or other fasteners. The dual positioning function of positioning post A11 and positioning post B12 ensures that the sleeve 13 and the pull rod tube 8 maintain axial stability during installation, avoiding the pull rod from jamming or shortening its service life due to installation deviation. In addition, the handle 15 and the telescopic tube 6 are connected by screws 5. The screws 5 pass through the handle and the telescopic tube in a direction perpendicular to the axis of the telescopic tube, forming a rigid fixation, ensuring that the handle 14 will not loosen or fall off relative to the telescopic tube 6 when the suitcase is pulled.

[0040] The design of hook 3 provides additional convenience for the use of the suitcase. Its working principle is as follows: When the operator needs to carry small items (such as handbags, backpacks, etc.), the handle or strap of the item can be placed into the hook groove 4 on the surface of hook 3. The hook groove 4 adopts an arc-shaped groove design, which can limit the strap of the item and prevent the item from slipping off the hook during the movement of the suitcase. At the same time, hook 3 is located on the inside of handle 15, so it will not protrude from the overall structure of the pull rod when not in use, avoiding scratches to the operator and not affecting the normal extension and retraction function of the pull rod.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
