Description

Technical Field

[0001] The present application relates to the technical field of luggage, and in particular to a luggage handle. Background Art

[0002] Currently, luggage is used to store items and is one of the most commonly used items during travel.

[0003] A bag in the related art includes a case body and a case handle, and the case body can be lifted or the case can be pushed or pulled with the help of the case handle.

[0004] Current modes of transportation include airplanes and high-speed trains. Aircraft have weight limits for luggage. After a bag is packed, it's impossible to determine if it's overweight until the passenger checks it in at the airport. If it's overweight, the passenger will incur additional charges. Summary of the Invention

[0005] In order to determine whether a bag is overweight, the present application provides a bag handle.

[0006] The present application provides a bag handle, which adopts the following technical solution:

[0007] A luggage handle comprises a handle body, wherein both ends of the handle body along the length direction are provided with a fixing box for being mounted on a luggage; a measuring structure is provided in the fixing box, the measuring structure includes a display component provided in the fixing box, the display component includes an indicator block provided in the fixing box, a pull rod inserted into the interior of the fixing box is provided on the end face of the handle body facing the fixing box, the pull rod is used to drive the indicator block to move, and an observation window is provided on the fixing box for observing the indicator block.

[0008] By adopting the above technical solution, when the operator lifts the luggage with the help of the handle body, the handle body drives the pull rod to move, and the pull rod drives the indicator block to move. When the indicator block appears in the observation window, it means that the luggage has reached the maximum load-bearing capacity, thereby estimating the weight of the luggage.

[0009] Optionally, the measuring structure includes a first fixing column arranged in the fixing box, the first fixing column is located on a side of the pull rod away from the handle body, and a first tension spring is provided between the pull rod and the first fixing column to connect the two.

[0010] By adopting the above technical solution, the operator drives the pull rod to move when lifting the luggage through the handle body, and the pull rod drives the indicator block to move. When the observation window appears on the indicator block, it means that the luggage has reached the maximum load-bearing capacity.

[0011] Optionally, the measuring structure includes a second fixed column and a slider arranged in a fixed box, the slider is located on the side of the pull rod away from the handle body, the second fixed column is located on the side of the slider away from the pull rod, a second tension spring connecting the second fixed column and the slider is provided between the two, and a clutch assembly for connecting or separating the slider and the pull rod is provided in the fixed box.

[0012] By adopting the above technical solution, the clutch assembly can connect the slider and the pull rod, so that the operator can observe whether the luggage has reached the maximum load-bearing capacity when lifting the luggage; since the second tension spring will experience elastic fatigue after repeated use, the clutch assembly does not connect the slider and the pull rod. When the operator lifts the luggage, the second tension spring will not be deformed, thereby reducing the number of times the second tension spring is deformed and increasing the service life of the second tension spring.

[0013] Optionally, an operating groove is provided on the end face of the slider facing the pull rod, and the clutch assembly includes a round rod rotatably connected to the operating groove, a first fixing rod is provided on the outer circumferential surface of the round rod, and an arc-shaped second fixing rod is provided on the end face of the first fixing rod along the circumference of the round rod, a punching hole is provided on the pull rod for the second fixing rod to be rotated into, and the clutch assembly also includes a positioning piece that makes the round rod difficult to rotate.

[0014] By adopting the above technical solution, when it is necessary to connect the pull rod and the slider, the round rod is driven to rotate to disengage the elastic block from the slot, the pull rod is driven to the specified position, the round rod is driven to rotate in the opposite direction, the second fixed rod passes through the punching hole, and then the pull rod is connected to the slider through the positioning piece, so that the second tension spring can be deformed when the pull rod moves; conversely, the second fixed rod is disengaged from the punching hole, so that the handle body no longer drives the second tension spring to move.

[0015] Optionally, the positioning member includes an elastic block arranged on the first fixing rod and / or the second fixing rod along the axis of the round rod, and a slot for the elastic block to be embedded is provided on the inner wall of the operating groove; when the elastic block is embedded in the slot, the second fixing rod cooperates with the slider to form a closed loop.

[0016] By adopting the above technical solution, when the elastic block is embedded in the slot, the first fixing rod and the second fixing rod are limited, making the second fixing plate difficult to rotate, that is, preventing the pull rod from separating from the slider, so that the pull rod can better drive the second tension spring to deform.

[0017] Optionally, the positioning member also includes a limit spring, which is in a compressed state. The limit spring is arranged at one end of the first fixed rod away from the elastic block, one end of the limit spring abuts against the first fixed rod, and the other end of the limit spring abuts against the bottom wall of the operating slot.

[0018] By adopting the above technical solution, the limit spring applies force to the first fixing rod, making it difficult for the elastic block to separate from the clamping block, thereby improving the connection effect; when the round rod rotates, the first fixing rod can move toward the limit spring, and at the same time the limit spring is compressed and deformed, making it easier for the elastic block to separate from the clamping slot; conversely, when the elastic block is aligned with the clamping slot, the limit spring resets and the elastic block is embedded in the clamping slot.

[0019] Optionally, the positioning member includes a clockwork spring sleeved outside the round rod, one end of the clockwork spring is connected to the round rod, and the other end of the clockwork spring is connected to the bottom wall of the operating slot. When the clockwork spring is not subjected to force, the second fixing rod cooperates with the slider to form a closed loop.

[0020] By adopting the above technical solution, when the round rod rotates to rotate and open the second fixed rod, the clockwork spring is deformed and no longer drives the round rod. The clockwork spring resets and drives the second fixed rod to reset, which has the effect of saving effort. In addition, the clockwork spring can make the second fixed rod difficult to rotate, preventing the pull rod from separating from the second rod.

[0021] Optionally, the fixed box includes a fixed seat, a shell covering the outside of the fixed seat is provided on the fixed seat, the clutch assembly also includes a driving member for driving the round rod to rotate, a guide hole in the shape of a long strip is provided on the side of the shell, the length direction of the fixed seat is the same as the length direction of the guide hole, the driving member includes a driving rod passing through the guide hole, the driving rod can slide in the guide hole, the driving rod is fixedly connected to the end face of the slider with a right prism, the end face of the round rod is provided with a mounting hole for the right prism to be embedded, and the mounting hole is arranged coaxially with the round rod.

[0022] By adopting the above technical solution, when the driving rod is rotated, the driving rod drives the right prism to rotate, and the right prism drives the round rod, the first fixed rod and the second fixed rod to rotate together, which facilitates connecting or separating the slider and the pull rod.

[0023] Optionally, the upper end surface of the fixing seat is fixedly connected to the limiting seat, and a limiting plate is provided on the end surface of the limiting seat away from the fixing seat, and the limiting plate is located on the side of the first tension spring away from the fixing seat.

[0024] By adopting the above technical solution, a limiting plate is set to limit the first tension spring so that when the first tension spring is deformed, the first tension spring is not easily separated from the first fixing column, so that the first tension spring can smoothly measure the weight of the luggage.

[0025] Optionally, a plurality of observation windows are provided, and the plurality of observation windows are distributed in an array along the length direction of the handle.

[0026] By adopting the above technical solution and setting multiple observation windows, the measurement is made more accurate; when the indicator blocks are displayed in different observation windows, they represent different weights of the luggage, allowing people to quickly estimate the weight of the luggage.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. When the operator lifts the bag with the handle, the handle drives the pull rod to move, and the pull rod drives the indicator block to move. When the indicator block appears in the observation window, it means that the bag has reached the maximum load-bearing capacity, thereby estimating the weight of the bag;

[0029] 2. Set up a clutch assembly. When the luggage needs to be measured, connect the pull rod and the slider to measure the weight of the luggage through the second tension spring; conversely, separate the pull rod and the slider to prevent the second tension spring from being stretched, thereby protecting the second tension spring.

[0042] The following is combined with Figure 1-11 This application is described in further detail.

[0043] Example 1

[0044] This embodiment discloses a bag handle. Figure 1 A luggage handle includes a handle body 1 and a fixing box 2.

[0045] Reference Figure 2 Two fixing boxes 2 are provided, and the handle body 1 is positioned between the two fixing boxes 2, with the two fixing boxes 2 being symmetrically arranged relative to each other. Two pull rods 11 are fixedly connected to the end surface of the handle body 1 facing the fixing boxes 2, and the two pull rods 11 are arranged horizontally. In other embodiments, the pull rods 11 can be one, three, or another number. A pull block 12 is fixedly connected between adjacent pull rods 11.

[0046] Reference Figure 1 and Figure 2 The fixing box 2 includes a fixing base 21 and a housing 22. Multiple mounting posts 211 are integrally formed below the fixing base 21. The ends of the mounting posts 211, facing away from the fixing base 21, define mounting grooves 2111 with internal threads on their inner walls. The fixing base 21 can be mounted on a bag using the mounting posts 211 and bolts. The end of the fixing base 21, facing away from the support posts 222, defines two grooves 212, with through-holes 2121 defined in their bottom walls.

[0047] Reference Figure 3 The housing 22 is formed with a receiving groove 221 at one end facing the fixing base 21, and the receiving groove 221 can be embedded in the fixing base 21. The inner wall of the receiving groove 221 is integrally formed with two support columns 222. In other embodiments, the present application provides one, three, or other number of support columns 222.

[0048] Reference Figure 3 The end surface of the support column 222 facing the fixing base 21 defines a support hole 2221, and the inner wall of the support hole 2221 defines an internal thread. The through hole 2121 is aligned with the support hole 2221. When the end of the support column 222 away from the bottom wall of the receiving groove 221 is in contact with the fixing base 21, the end surface of the housing 22 defining the receiving groove 221 is coplanar with the bottom wall of the fixing base 21 away from the support column 222.

[0049] Reference Figure 1 and Figure 3 A first fastener 3 is provided between the housing 22 and the fixing base 21, connecting the two. The first fastener 3 includes a first screw 31. The first screw 31 passes through the groove 212 and the through hole 2121 in sequence and is threadedly connected to the support hole 2221. When the housing 22 and the fixing base 21 are connected by the first screw 31, the head of the first screw 31 is embedded in the groove 212.

[0050] Reference Figure 2 and Figure 3 The end surface of the fixing base 21 away from the mounting post 211 is fixedly connected to a fixing plate 213. The end surface of the fixing plate 213 near the handle body 1 is in contact with the inner wall of the accommodating groove 221 near the handle body 1. When the fixing base 21 is installed in the housing 22, the fixing plate 213 is located between the two support posts 222, and the end surface of the fixing plate 213 away from the mounting post 211 contacts the bottom wall of the accommodating groove 221.

[0051] Reference Figure 2 and Figure 4 The fixing plate 213 has a fixing hole 2131 defined on its end facing the handle body 1. The lower inner wall of the fixing hole 2131 extends through the fixing plate 213, toward the fixing base 21. The fixing hole 2131 allows both the pull rod 11 and the pull block 12 to pass through. A first stop 2132 is integrally formed on the upper inner wall of the fixing hole 2131. The distance between the first stop 2132 and the fixing plate 213 is slightly greater than the thickness of the pull block 12. The first stop 2132 is fixedly connected to the second stop 2133 on the end facing away from the handle body 1.

[0052] Reference Figure 2 and Figure 3A fixing strip 214 is integrally formed on the end surface of the fixing base 21 away from the mounting post 211. The fixing strip 214 is located on the side of the fixing plate 213 away from the handle body 1. The fixing strip 214 surrounds the fixing base 21, and both ends of the fixing strip 214 are fixedly connected to the fixing plate 213. The inner wall of the accommodating groove 221 is in contact with the fixing strip 214.

[0053] Reference Figure 2 and Figure 3 The shell 22 has two through-holes 223 on its end surface facing the handle body 1, and the two through-holes 223 penetrate the shell 22 in a direction away from the bottom wall of the accommodating groove 221. The through-holes 223 are aligned with the fixing holes 2131. When the shell 22 is covered on the fixing seat 21, the through-holes 223 can be used for the pull rod 11 to be embedded, and the support column 222 close to the handle body 1 and the shell 22 both partially block the fixing holes 2131. When the pull block 12 moves toward the fixing plate 213, in the first case, the pull block 12 will be blocked by the second stop block 2133. In the second case, the pull block 12 will be blocked by the support column 222 when passing through the fixing hole 2131, making it difficult for the pull rod 11 to separate from the fixing box 2.

[0054] Reference Figure 1 and Figure 2 The housing 22 is integrally formed with a support block 224 on the end surface facing the handle body 1. When the operator does not use the handle body 1 to carry a bag, the support block 224 contacts the lower end surface of the handle body 1.

[0055] Reference Figure 2 and Figure 4 Two measuring structures 4 are disposed within the fixed housing 2, symmetrically arranged along the central axis of the fixed base 21. The measuring structures 4 include a first fixing post 41, a first tension spring 42, and a display assembly 43. The first fixing post 41 is fixedly connected to the end face of the fixed base 21 facing the fixed plate 213 and is located on the side of the fixed plate 213 facing away from the handle body 1. One end of the first tension spring 42 is connected to the first fixing post 41, and the other end is connected to the pull rod 11.

[0056] Reference Figure 2 and Figure 4 The display assembly 43 includes an indicator block 431 and an insert block 432. The indicator block 431 is colored for easy viewing. The insert block 432 is fixedly connected to the end surface of the indicator block 431 facing the fixed base 21. The pull block 12 has a socket into which the insert block 432 can be inserted. In other embodiments, the pull rod 11 has a socket for inserting the insert block 432, and the indicator block 431 is mounted on the pull rod 11.

[0057] Reference Figure 2 and Figure 4The upper surface of the housing 22 defines two observation windows 225, arranged in an array away from the handle body 1. The indicator block 431 can be observed through the observation windows 225 during movement. Different observation windows 225 represent load-bearing areas of different weights. When the indicator block 431 is observed by different observation windows 225, it indicates that the bag has reached a different weight value. In other embodiments, the number of observation windows 225 may be one, three, or another number.

[0058] Reference Figure 2 and Figure 4 In this application, two measuring structures 4 are connected to each end of the handle body 1. That is, when the handle body 1 is connected to four first tension springs 42, the indicator block 431 appears in the observation window 225 away from the handle body 1, indicating that the luggage weight limit is 20kg; the indicator block 431 appears in the observation window 225 close to the handle body 1, indicating that the luggage weight limit is 40kg. In other embodiments, by replacing the first tension springs 42 with different elastic coefficients, the weight represented by the indicator block 431 when it appears in the observation window 225 can be changed.

[0059] Reference Figure 2 The upper end surface of the fixed seat 21 is fixedly connected to a limit seat 215, which is located between the two first tension springs 42. A limit plate 216 is provided on the end surface of the limit seat 215 away from the fixed seat 21. The limit plate 216 is located on the side of the first tension spring 42 away from the fixed seat 21. A second fastener 5 is provided between the limit plate 216 and the limit seat 215, connecting the two. The second fastener 5 is a second screw 51.

[0060] The implementation principle of Example 1 is as follows: when the operator lifts the bag through the handle body 1, the handle body 1 pulls the pull rod 11, and the pull rod 11 pulls the first tension spring 42 to deform. The operator observes the indicator block 431 through the observation window 225 to determine whether the bag is overweight.

[0061] Example 2

[0062] Reference Figure 5 The difference between this embodiment and embodiment 1 is that the measuring structure 4 includes a second fixing column 44 , a second tension spring 45 and a slider 46 .

[0063] Reference Figure 5 The second fixing post 44 is fixedly connected to the end surface of the fixing base 21 facing the fixing plate 213. The second fixing post 44 is located on the side of the fixing plate 213 away from the handle body 1. One end of the second tension spring 45 is connected to the second fixing post 44, and the other end of the second tension spring 45 is connected to the slider 46.

[0064] Reference Figure 5The upper end surface of the fixed seat 21 is fixedly connected with a positioning bar 217 and a positioning protrusion. The positioning bar 217 is located on the side of the slider 46 away from the handle body 1. When the two sliders 46 are not subjected to the pulling force of the pull rod 11, the end surface of the slider 46 away from the fixed plate 213 collides with the positioning bar 217, and the end surface of the slider 46 away from the fixed seat 21 collides with the limit plate 216, which plays a role of limiting. The positioning protrusion is located on the side of the positioning bar 217 close to the slider 46 and is located between the two sliders 46. Both end surfaces of the positioning protrusion along the axis direction of the round rod 61 are in contact with the slider 46, which plays a role of limiting. In other embodiments, the indicator block 431 can be set on the slider 46.

[0065] Reference Figure 6 and Figure 7 The slider 46 is provided with a clutch assembly 6, which is used to connect and disconnect the slider 46 from the pull rod 11. An operating slot 461 is defined at the end of the slider 46 away from the pull rod 11. The operating slot 461 vertically penetrates the slider 46. Circular holes 462 are defined on the two opposing inner walls of the operating slot 461.

[0066] Reference Figure 6 and Figure 7 The clutch assembly 6 comprises a round rod 61, a first fixing rod 62, a second fixing rod 63, a driving member 64, and a positioning member 65. The round rod 61 is rotatably coupled to the circular hole 462. The first fixing rod 62 is fixedly coupled to the outer circumferential surface of the round rod 61. The second fixing rod 63 is fixedly coupled to the end surface of the first fixing rod 62 along the circumferential direction of the round rod 61 and has an arc-shaped shape. A punched hole is formed in the pull rod 11 to allow the second fixing rod 63 to pass through.

[0067] Reference Figure 7 and Figure 8 The driving member 64 includes a driving rod 641, a right prism 642, and a driving disk 643. A guide hole 226 is defined in the inner wall of the housing 22 along the axis of the round rod 61. The guide hole 226 is elongated, and its length aligns with the length of the fixing base 21. The driving rod 641 is inserted into the guide hole 226 and is slidable therein.

[0068] Reference Figure 6 and Figure 7 The right prism 642 is fixedly connected to the end face of the drive rod 641 facing the slider 46. In the present application, the right prism 642 is a right hexagonal prism. The end face of the round rod 61 is provided with a mounting hole 611. The cross section of the mounting hole 611 is the same as that of the right prism 642. The mounting hole 611 is coaxial with the round rod 61 and can accommodate the right prism 642. The two right prisms 642 located in the same fixed box 2 are close to each other and fit together in the end face. Furthermore, the right prism 642 is fixedly connected to the adjacent right prism 642.

[0069] Reference Figure 6 and Figure 8 The driving disk 643 is fixedly connected to the end face of the driving rod 641 away from the slider 46, and the end face of the driving disk 643 facing the slider 46 is in contact with the outer surface of the housing 22. The two driving disks 643 can limit the movement of the driving rod 641 toward the slider 46.

[0070] Reference Figure 6 and Figure 7 Positioning member 65 includes a spring 651, which is sleeved around rod 61 and located on one side of first fixing rod 62 along the axis of rod 61. One end of spring 651 is connected to rod 61, while the other end is connected to the bottom wall of operating slot 461. When spring 651 is unloaded, second fixing rod 63 and slider 46 form a closed loop.

[0071] The implementation principle of Example 2 is: when the weight of the luggage needs to be measured, the driving disk 643 is rotated, and the driving disk 643 drives the driving rod 641, the round rod 61, the first fixed rod 62, and the second fixed rod 63 to rotate together, and at the same time drives the spring spring 651 to deform. When the operator lifts the luggage through the handle body 1, the handle body 1 pulls the pull rod 11, and the pull rod 11 pulls the second tension spring 45 to deform. The indicator block 431 is observed from the observation window 225 to determine whether the luggage is overweight.

[0072] Example 3

[0073] Reference Figure 9 The difference between this embodiment and embodiment 2 is that the positioning member 65 also includes an elastic block 652, which is fixedly connected to the side of the first fixing rod 62 away from the clockwork spring 651, and the end surface of the elastic block 652 away from the first fixing rod 62 is set to an arc surface.

[0074] Reference Figure 9 The operating slot 461 is provided with two slots 463 on its inner wall, which is provided with a circular hole 462. The two slots 463 are arranged in a circular array along the axis of the circular rod 61. The slots 463 allow the elastic block 652 to be inserted. When the elastic block 652 is inserted into one slot 463, the second fixing rod 63 cooperates with the slider 46 to form a closed loop; when the elastic block 652 is inserted into another slot 463, the second fixing rod 63 opens relative to the slider 46. In other embodiments, the elastic block 652 can be provided on the end surface of the second fixing rod 63 facing the circular hole 462; or the end surfaces of the first fixing rod 62 and the second fixing rod 63 facing the circular hole 462 are both provided with elastic blocks 652.

[0075] The implementation principle of Example 3 is: when the driving disk 643 is rotated, the driving disk 643 drives the driving rod 641, the round rod 61, the first fixed rod 62, the second fixed rod 63, and the elastic block 652 to rotate together. When the elastic block 652 is embedded in the card slot 463, it can limit the rotation of the round rod 61.

[0076] Example 4

[0077] Reference Figure 10 and Figure 11 This embodiment differs from Example 2 in that the positioning member 65 includes an elastic block 652, which is fixedly connected to the end surface of the first fixing rod 62 facing the circular hole 462. The end surface of the elastic block 652 facing away from the first fixing rod 62 is configured as an arcuate surface. Two latching grooves 463 are formed on the inner wall of the operating slot 461, where the circular hole 462 is located. The two latching grooves 463 are arranged in a circular array along the axis of the circular rod 61. The latching grooves 463 accommodate the elastic block 652. When the elastic block 652 is inserted into the latching grooves 463, the second fixing rod 63 and the slider 46 form a closed loop. When the elastic block 652 is inserted into the other latching groove 463, the second fixing rod 63 opens relative to the slider 46. In other embodiments, the elastic block 652 may be provided on the end surface of the second fixing rod 63 facing the circular hole 462, or the elastic block 652 may be provided on the end surfaces of both the first and second fixing rods 62, 63 facing the circular hole 462.

[0078] Reference Figure 10 and Figure 11 Furthermore, the positioning member 65 further includes a limiting spring 653, which is sleeved around the round rod 61 and located at the end of the first fixing rod 62 away from the elastic block 652. When the limiting spring 653 is in a compressed state, one end of the limiting spring 653 abuts the end surface of the first fixing rod 62 away from the elastic block 652, while the other end of the limiting spring 653 abuts the inner wall of the operating slot 461. When the elastic block 652 is inserted into the retaining slot 463, the limiting spring 653 prevents the elastic block 652 from being removed from the retaining slot 463.

[0079] The working principle of Example 4 is as follows: when the pull rod 11 is separated from the slider 46, the driving disk 643 is rotated, which drives the driving rod 641, the round rod 61, the first fixing rod 62, the second fixing rod 63, and the elastic block 652 to rotate together, causing the second fixing rod 63 to disengage from the punched hole in the pull rod 11. At the same time, the elastic block 652 disengages from the slot 463 until the elastic block 652 is embedded in another slot 463. Conversely, the pull rod 11 is connected to the slider 46.

[0080] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present application should be included in the scope of protection of the present application.
