As shown in fig. 1 to 3, the luggage case with an external pull rod according to the embodiment of the present invention includes a case body 100, a guide sleeve 120 and a pull rod assembly 200, wherein the outer sidewall of the case body 100 is recessed to form a mounting groove 101, the guide sleeve 120 is fixedly connected with the case body 100 and disposed in the mounting groove 101, and the pull rod assembly 200 includes a guide rod 210 and a handle 220. Specifically, the guide bar 210 is disposed through the guide sleeve 120 and slidably connected to the guide sleeve 120, the handle 220 is fixedly connected to the guide bar 210 and used for driving the guide bar 210 to move along the central line direction of the guide sleeve 120, and the roller 110 is disposed at the bottom of the box 100, and the handle 220 cooperates with the roller 110 to pull the box 100. In some embodiments, the guide sleeve 120 and the mounting groove 101 are square, and the guide bar 210 does not rotate in the guide sleeve 120. It will be readily appreciated that when a user pulls on the luggage case, the user is positioned on the side of the case 100 facing the guide bar 210, and the case 100 is tilted with respect to the ground.
It should be noted that, guide pin bushing 120 is fixed to be set up in the mounting groove 101 of box 100 outer wall, guide arm 210 wears to locate guide pin bushing 120 in order to realize flexible function, incline box 100 pulling when guide arm 210, support box 100 in the time of guide arm 210 tractive, the user stimulates the suitcase more easily, and guide pin bushing 120 and box 100 butt, atress dispersion during the slope, be difficult to damage, guide arm 210's life is higher, in addition, the muscle structure of strengthening box 100 rigidity has been formed when box 100 indent forms mounting groove 101, box 100's rigidity is better.
In some embodiments of the present invention, as shown in fig. 1 and 2, the outer sidewall of the box 100 is recessed to form a receiving groove 102 communicated with the mounting groove 101, and the receiving groove 102 is used for receiving the handle 220. When the handle 220 is retracted into the box 100, the handle 220 can be received in the receiving groove 102, and therefore the integrity of the box 100 is better, and the handle 220 does not protrude out of the box 100, so that the box 100 is more convenient to receive.
In some embodiments of the present invention, as shown in fig. 1 and 3, the pulling rod assembly 200 further includes a connecting rod 230, the connecting rod 230 is sleeved on the guide rod 210, specifically, the connecting rod 230 is fixed to the box 100 and located at one end of the guide sleeve 120 facing the handle 220, and there are two guide sleeves 120, the connecting rod 230 is provided with two fixing portions 231, and the fixing portions 231 are in one-to-one correspondence with the guide sleeves 120 and are connected to the guide sleeves 120. Similar to the guiding function of the guide sleeve 120 on the guide rod 210, the connecting rod 230 also guides the linear motion of the guide rod 210, and the connecting rod 230 connects the two guide sleeves 120, so that the connection between the two guide sleeves 120 is more stable, and the guiding effect on the guide rod 210 is better. For example, the fixing portion 231 is provided with a clamping block 2311, the guide sleeve 120 is provided with a clamping hole 121 corresponding to the clamping block 2311, and the clamping block 2311 is clamped and fixed with the clamping hole 121.
Referring to fig. 4, in some embodiments of the present invention, the inner peripheral wall of the box 100 is fixedly provided with a first reinforcing block 130 and a second reinforcing block 140, the first reinforcing block 130 is located at one end of the guide sleeve 120 and covers a part of the guide sleeve 120, and the second reinforcing block 140 is located at the other end of the guide sleeve 120 and covers a part of the guide sleeve 120, so that the rigidity of the joint between the box 100 and the two ends of the guide sleeve 120 can be effectively enhanced. It can be easily understood that the probability of stress concentration occurring at the two ends of the guide sleeve 120 connected to the box 100 is the greatest, and if the user tilts the box 100 by pulling the handle, the box 100 is stressed the most at the two ends connected to the guide sleeve 120, so by providing the first reinforcing block 130 and the second reinforcing block 140, the box 100 can better withstand the extreme use of the guide bar 210 by the user, such as by prying the guide bar 210 excessively or by other wrong use modes of the guide bar 210.
Alternatively, the guide sleeve 120 and the connecting rod 230 are directly fixed to the outer wall of the box 100 by welding or bonding. Further, in some embodiments, the guide sleeve 120 is fixedly mounted to the box 100 through the first reinforcing block 130, and the connecting rod 230 is fixedly mounted to the box 100 through the second reinforcing block 140. For example, the first reinforcing block 130 is located at an end of the guide sleeve 120 away from the handle 220, the first reinforcing block 130 is provided with a first fixing hole 131, and the first reinforcing block 130 and the guide sleeve 120 are fixed by a screw located in the first fixing hole 131. The second reinforcing block 140 is located at one end of the guide sleeve 120 facing the handle 220, the second reinforcing block 140 is provided with a second fixing hole 141, and the second reinforcing block 140 and the connecting rod 230 are fixed by a screw located in the second fixing hole 141.
Referring to fig. 1 and 2, in some embodiments of the present invention, the mounting groove 101 extends along a height direction of the case 100, and correspondingly, the guide bar 210 is disposed along a vertical direction, so that a user can use the guide bar 210 conveniently. In some embodiments, the box 100 has a narrow top and a wide bottom, so that the center of gravity of the box 100 is located downward, and the user can pull the box 100 more smoothly.
In order to facilitate the user to clearly define and fix the extending and retracting positions of the guide rod 210, referring to fig. 3, the guide sleeve 120 is provided with a first limiting groove 122 and a second limiting groove 123 at intervals along the length direction of the guide sleeve 120, and the guide rod 210 is provided with a limiting block (not shown in the figure) which moves between the first limiting groove 122 and the second limiting groove 123. For example, the limiting block is elastically mounted on the guide rod 210, the first limiting groove 122 is located below the second limiting groove 123, and when the user retracts the guide rod 210 into the box body 100 completely, the limiting block is clamped and fixed with the first limiting groove 122; when the user completely extends the guide rod 210 out of the box 100, the limiting block is fixed to the second limiting groove 123 in a clamping manner.
Optionally, the material of the box 100 is PC material. Compared with three types of box bodies 100 of ABS, PP and ABS + PC, the pure PC box is lighter and thinner and has better flexibility, pressure resistance and impact resistance.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
