Description

Technical Field

[0001] This utility model relates to a luggage structure, and more particularly to a trolley case with a diagonal pull rod. Background Technology

[0002] A rolling suitcase is a travel bag equipped with a retractable handle and wheels. It is one of the most common and convenient travel items in modern life, allowing users to easily move the suitcase by simply pulling it along the handle without having to carry it by hand.

[0003] like Figure 7 As shown, a typical suitcase usually includes a first case shell 10a and a second case shell 20a arranged opposite to each other, a set of wheels 30a mounted on the first case shell 10a, another set of wheels 30a mounted on the second case shell 20a, and a pull rod 40a, with the pull rod 40a located on the side of the second case shell 20a facing away from the first case shell 10a.

[0004] For traditional rolling suitcases, it's best to tilt them and drag them forward. However, this puts the weight on the user's hands, making dragging the suitcase difficult. Therefore, some users try pushing it horizontally. However, when pushing a rolling suitcase horizontally, it tends to tilt forward, potentially causing it to tip over and inconvenience the user. Utility Model Content

[0005] Therefore, it is necessary to provide a trolley case with a diagonal pull rod to address the shortcomings of existing technologies.

[0006] A trolley case with a diagonal pull rod includes two case shells and a pull rod assembly mounted on both case shells. The pull rod assembly is adjustable in length on both case shells. Each case shell is also provided with a guide groove that extends into the interior of the case shell in a forward and downward inclined direction. The pull rod assembly includes two guide sleeves, two pull rod bodies that slide on the two guide sleeves respectively, a first handle mounted on one of the pull rod bodies, a second handle mounted on the other pull rod body, a positioning head mounted on the first handle, and a positioning sleeve movably mounted on the first and second handles. The first and second handles are arranged opposite each other in the horizontal direction. During assembly, the two guide sleeves are installed in the guide grooves along the extension direction of the guide grooves. The pull rod bodies correspond one-to-one with the guide sleeves and are inserted into the guide sleeves. The pull rod bodies of the pull rod assembly are inclined forward and downward.

[0007] In one embodiment, both the outer peripheral surfaces of the first handle and the second handle are provided with drum-shaped protrusions arranged side by side.

[0008] In one embodiment, the positioning sleeve includes a main body and an adhesive part mounted on the main body. Both the main body and the adhesive part are hollow tubular structures, and the adhesive part is made of silicone or rubber.

[0009] In one embodiment, the first handle has a fixing hole at one end near the second handle, and the second handle has a positioning hole at one end near the first handle; the positioning head has a first positioning segment and a second positioning segment at both ends, and the shapes of the first positioning segment and the second positioning segment correspond to the fixing hole and the positioning hole, respectively; the first positioning segment of the positioning head is fixedly installed in the fixing hole of the first handle, and when the two shells are in the closed state, the second positioning segment of the positioning head is inserted into the positioning hole of the second handle.

[0010] In one embodiment, the shell includes a shell body, a rear side plate connected to the rear edge of the shell body, a front side plate connected to the front edge of the shell body, a top plate connected to the top edge of the shell body, and a bottom plate connected to the bottom edge of the shell body. The front side plate, rear side plate, top plate, and bottom plate together form an inner groove with an opening.

[0011] In one embodiment, the housing is further provided with a functional surface and a functional block at the junction of the top plate and the rear side plate. The functional surface is inclined backward and downward, and the functional block is connected to the functional surface near the main body of the housing. When the pull rod body is fully inserted into the guide sleeve, the first handle and the second handle are located between the two functional blocks.

[0012] In one embodiment, the guide groove is inclined through the functional block in a forward-downward direction.

[0013] In one embodiment, the assembly further includes a frame edge assembly mounted on the two shells, the frame edge assembly consisting of two frame edges, one frame edge being mounted on the edge of the inner groove opening of one shell and the other frame edge being mounted on the edge of the inner groove opening of the other shell.

[0014] The beneficial effects of this utility model of a trolley case with a slanted pull rod are as follows: By setting a guide groove on the case shell, the guide groove extends into the case shell in a forward and downward inclined direction. The pull rod assembly is installed in the guide groove, and the pull rod body of the pull rod assembly is set in a forward and downward inclined direction. During use, when the user pushes the first handle or the second handle forward and downward, since the pull rod body is set in a forward and downward inclined direction, the forward and downward pushing force can be decomposed into two forces in the forward and downward directions, so that the trolley case can be pushed more easily. At the same time, it effectively prevents the trolley case from tipping forward. The overall structure is flexible and highly practical. Attached Figure Description

[0026] Please see Figures 1 to 6 This utility model provides a trolley case with a diagonal pull rod, including two case shells 10, a frame assembly 20 and a lock 30 installed on the two case shells 10, a first pulley group 40 installed on one of the case shells 10, a second pulley group 50 installed on the other case shell 10, and a pull rod assembly 60 installed on both case shells 10. The pull rod assembly 60 can be length adjusted on the two case shells 10, so that it is in an inward retracted state or an outward open state.

[0027] The shell 10 includes a shell body 11, a rear side plate 12 connected to the rear edge of the shell body 11, a front side plate 13 connected to the front edge of the shell body 11, a top plate 14 connected to the top edge of the shell body 11, and a bottom plate 15 connected to the bottom edge of the shell body 11. The front side plate 13, rear side plate 12, top plate 14, and bottom plate 15 together form an inner groove with an opening (not shown in the figure). A first pulley assembly 40 is installed on the bottom plate 15 of one shell 10, and a second pulley assembly 50 is installed on the bottom plate 15 of the other shell 10.

[0028] The frame assembly 20 consists of two frames, one of which is installed on the edge of the inner groove of one housing 10, and the other is installed on the edge of the inner groove of another housing 10. The lock 30 is divided into two parts and is installed on the rear side plates 12 of the two housings 10 respectively. After the lock 30 is opened, the housing 10 can be further opened. Conversely, when the lock 30 is in the locked state, the lock 30 locks the two housings 10, and the shell bodies 11 of the two housings 10 are arranged opposite each other.

[0029] In addition, the shell 10 is provided with a functional surface 16 and a functional block 17 at the junction of the top plate 14 and the rear side plate 12. The functional surface 16 is inclined backward and downward, and the functional block 17 is connected to the functional surface 16 near the shell body 11. The shell 10 is also provided with a guide groove 18, which is inclined forward and downward, passes through the functional block 17, and extends into the interior of the shell 10.

[0030] The pull rod assembly 60 includes two guide sleeves 61, two pull rod bodies 62 respectively slidably mounted on the two guide sleeves 61, a first handle 63 mounted on one of the pull rod bodies 62, a second handle 64 mounted on the other pull rod body 62, a positioning head 65 mounted on the first handle 63, and a positioning sleeve 66 movably mounted on the first handle 63 and the second handle 64. The first handle 63 and the second handle 64 are arranged opposite each other in the horizontal direction. The outer peripheral surfaces of the first handle 63 and the second handle 64 are provided with bulging protrusions (631, 641) arranged side by side. The first handle 63 has a square fixing hole 632 at one end near the second handle 64, and the second handle 64 has a circular positioning hole 642 at one end near the first handle 63. The positioning head 65 has a first positioning segment 651 and a second positioning segment 652 at both ends, and the shapes of the first positioning segment 651 and the second positioning segment 652 correspond to the fixing hole 632 and the positioning hole 642, respectively. The positioning sleeve 66 includes a main body 661 and an adhesive part 662 installed on the main body 661. Both the main body 661 and the adhesive part 662 are hollow tubular structures. The adhesive part 662 is silicone or rubber with certain elastic properties.

[0031] During assembly, the two guide sleeves 61 are installed in the guide groove 18 along the extension direction of the guide groove 18. The pull rod body 62 corresponds one-to-one with the guide sleeve 61 and is inserted into the guide sleeve 61. The first positioning section 651 of the positioning head 65 is fixedly installed in the fixing hole 632 of the first handle 63. When the two housings 10 are in the closed state, the second positioning section 652 of the positioning head 65 is inserted into the positioning hole 642 of the second handle 64. When the pull rod body 62 is fully inserted into the guide sleeve 61, the first handle 63 and the second handle 64 are located between the two functional blocks 17.

[0032] When the bag needs to be moved, the pull rod body 62 is pushed outward until it is locked to the guide sleeve 61 by the locking mechanism (the setting of the locking mechanism is well known to those skilled in the art and will not be described in detail here). Then, the positioning sleeve 66 is moved horizontally so that its two ends are respectively fitted onto the first handle 63 and the second handle 64. By fitting the positioning sleeve 66 onto the first handle 63 and the second handle 64, the connection strength between the first handle 63, the second handle 64, and the positioning head 65 can be improved. Furthermore, a protrusion 631 is provided on the first handle 63, a protrusion 641 is provided on the second handle 64, and a rubber part 662 is provided on the positioning sleeve 66. Through the cooperation between the rubber part 662 and the protrusions (631, 641), the rubber part 662 is effectively prevented from sliding freely on the first handle 63 or the second handle 64.

[0033] The beneficial effects of this utility model of a trolley case with a diagonal pull rod are as follows: By providing a guide groove 18 on the case shell 10, the guide groove 18 extends into the case shell 10 in a forward and downward inclined direction. The pull rod assembly 60 is installed in the guide groove 18, and the pull rod body 62 of the pull rod assembly 60 is inclined forward and downward. During use, when the user pushes the first handle 63 or the second handle 64 forward and downward, since the pull rod body 62 is inclined forward and downward, the forward and downward pushing force can be decomposed into forces in the forward and downward directions, thus making it easier to push the trolley case. At the same time, it effectively prevents the trolley case from tipping forward. The overall structure is flexible and highly practical.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
