Specific embodiments

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] As Figure 1 shown, a luggage pull rod box with a climbing mechanism includes a bottom box 1, the left side of the bottom box 1 is fixedly connected with a box cover 2 through a zipper, the right side of the bottom box 1 is slidably connected with a pull rod 3, two power mechanisms 4 distributed symmetrically front and back are movably installed on the lower right side of the bottom box 1, a stair-climbing mechanism 5 is fixedly connected to the lower side of the bottom box 1, and a support mechanism 6 is fixedly connected to the position near the bottom on the right side of the bottom box 1.

[0027] It should be noted that the power mechanism 4 contains components such as a power assembly and rollers, and the power assembly drives the rollers to rotate, so that the whole moves.

[0028] As Figure 2 shown, the stair-climbing mechanism 5 includes a bottom frame 51, the inner lower surface of the bottom frame 51 is fixedly connected to the lower side of the bottom box 1, two limiting plates 510 distributed symmetrically front and back are fixedly connected to the position near the bottom inside the bottom box 1, a linkage frame 52 is slidably connected to the inside of the limiting plates 510, and the left convex block on the right wall of the linkage frame 52 is slidably connected to the limiting groove opened on the left wall of the limiting plate 510.

[0029] It should be noted that the limiting plate 510 is used to limit the linkage frame 52 to prevent the front and back sides of the linkage frame 52 from deflecting when the linkage frame 52 moves up and down.

[0030] As Figure 2 、 Figure 3As shown in the figure, two symmetrically distributed rotating frames 53 are rotatably connected to the front and rear sides of the linkage frame 52 near the left side of the bottom box 1, and the rotating frames 53 are located outside the bottom box 1. Three annularly distributed first runners 54 are rotatably connected to the positions near the edges of the two sides of the rotating frames 53 away from the bottom box 1. Two symmetrically distributed screws 56 are slidably connected to the front and rear walls of the bottom frame 51. The ends of the two screws 56 close to each other are rotatably connected to a top plate 55, and the top plate 55 is located inside the bottom box 1. Two annularly distributed butterfly plates 58 are fixedly connected to the outer sides of the outer walls of the two screws 56 away from each other. The outer walls of the two screws 56 are movably sleeved with the screws 56, and the clamping plate 57 is located on the side of the bottom frame 51 away from the bottom box 1. The upper side of the top plate 55 is fixedly connected to the lower sides of the front and rear walls of the linkage frame 52.

[0031] It should be noted that by rotating the butterfly plate 58, the screw 56 rotates, causing the top plate 55 and the clamping plate 57 to loosen the clamping of the bottom frame 51, enabling the linkage frame 52 to move up and down. Move the rotating frame 53 to the lowest position, and then rotate the butterfly plate 58 again to fix the linkage frame 52 in this position.

[0032] As Figure 3 shown, two symmetrically distributed chutes 59 are opened on the outer sides of the front and rear walls of the bottom frame 51. The convex blocks on the side of the clamping plate 57 close to the bottom box 1 are slidably connected to the inside of the chutes 59.

[0033] It should be noted that the chute 59 is used to limit the clamping plate 57. When the clamping plate 57 and the top plate 55 loosen the clamping of the bottom frame 51, the clamping plate 57 deflects itself, affecting the operation.

[0034] As Figure 1 、 Figure 4 shown, the support mechanism 6 includes a mounting frame 61. The left side of the mounting frame 61 is fixedly connected to the position near the bottom on the right side of the bottom box 1. The front and rear ends of the mounting frame 61 are rotatably connected to hollow rods 62. The inner sides of the two hollow rods 62 are movably sleeved with support rods 63. The upper ends of the two support rods 63 are fixedly connected to first springs 64, and the first springs 64 are located inside the hollow rods 62. The lower ends of the two support rods 63 are rotatably connected to second runners 65.

[0035] It should be noted that when the second runner 65 touches the ground, the whole is in an inclined state, and part of the mass is pressed on the second runner 65. The first spring 64 is a shock-absorbing spring, which contains a damping mechanism to reduce the vibration generated by the whole during movement on the second runner 65.

[0036] As Figure 4 、 Figure 5As shown, on the side of the hollow rods 62 close to each other and near the upper end, there is a transmission rod 66 fixedly connected. At a position near the middle of the outer wall of the transmission rod 66, there is a first bevel gear 67 fixedly connected. In the middle of the right side of the inner side of the mounting bracket 61, there is a second bevel gear 68 rotatably connected. The front side of the second bevel gear 68 is meshed and connected with the right side of the first bevel gear 67. On the right side of the second bevel gear 68, there is a knob 610 fixedly connected.

[0037] It should be noted that when the knob 610 is rotated, the second bevel gear 68 is caused to rotate. When the second bevel gear 68 rotates, it drives the first bevel gear 67 to rotate. When the first bevel gear 67 rotates, it drives the transmission rod 66 to rotate. When the transmission rod 66 rotates, the hollow rods 62 on both sides rotate synchronously.

[0038] As Figure 5 shown, the outer wall of the knob 610 is provided with friction lines.

[0039] It should be noted that the friction lines are used to increase the friction force of the hand on the knob 610, facilitating the user to rotate the knob 610.

[0040] As Figure 1 、 Figure 5 shown, on the right side of the bottom box 1 and near the bottom, there is a self-locking component 69 fixedly connected. The self-locking component 69 includes a fixed block 691. The left side of the fixed block 691 is fixedly connected to the middle of the right side of the bottom box 1 near the bottom. The inner side of the fixed block 691 is movably sleeved with a limiting rod 692. The upper end of the limiting rod 692 is fixedly connected with a top block 693. The shape of the top block 693 is a right trapezoid, and the inclined surface of the top block 693 faces upward. At a position near the edge of the front side of the first bevel gear 67, there are several annularly distributed clamping blocks 694 fixedly connected. The outer wall of the limiting rod 692 is movably sleeved with a second spring 695, and the second spring 695 is located above the fixed block 691. The lower end of the limiting rod 692 is fixedly connected with a sliding button 696.

[0041] It should be noted that when the transmission rod 66 rotates counterclockwise, the clamping block 694 pushes the inclined surface on the upper side of the top block 693, causing the top block 693 to move downward, so that the top block 693 does not affect the rotation of the transmission rod 66. When the transmission rod 66 rotates clockwise, the clamping block 694 abuts against the lower side of the top block 693, causing the first bevel gear 67 to be unable to rotate, so that the transmission rod 66 is fixed. Pull down the sliding button 696, causing the top block 693 to move downward, so that the top block 693 and the clamping block 694 are separated, causing the transmission rod 66 to be able to rotate clockwise.

[0042] The working principle of the utility model is as follows: first, the power mechanism 4 contains a power assembly, a roller and other components. The power assembly drives the roller to rotate, so that the whole moves. When the second rotating wheel 65 contacts the ground, the whole is in an inclined state, and a part of the mass is pressed on the second rotating wheel 65. The first spring 64 is a shock-absorbing spring, which contains a damping mechanism to reduce the vibration of the whole on the second rotating wheel 65 when it moves. Turn the knob 610 to cause the second bevel gear 68 to rotate. When the second bevel gear 68 rotates, it drives the first bevel gear 67 to rotate. When the first bevel gear 67 rotates, it drives the transmission rod 66 to rotate. The transmission rod When the transmission rod 66 rotates, the hollow rods 62 on both sides rotate synchronously. When the transmission rod 66 rotates counterclockwise, the block 694 pushes the inclined surface on the upper side of the top block 693, so that the top block 693 moves down, so that the top block 693 does not affect the rotation of the transmission rod 66. When the transmission rod 66 rotates clockwise, the block 694 supports the lower side of the top block 693, so that the first bevel gear 67 cannot rotate, so that the transmission rod 66 is fixed. The sliding button 696 is pulled down to move the top block 693 downward, so that the top block 693 and the block 694 are separated, so that the transmission rod 66 can rotate clockwise. By turning the knob 610, the hollow rod 62 is rotated to tilt the suitcase, so that the roller and the second rotating wheel 65 on the power mechanism 4 are in contact with the ground, and the power assembly on the power mechanism 4 drives the roller to rotate, making the whole body lighter when climbing a slope. At the same time, the user can reduce the load of the power mechanism 4 as a whole by pulling the pull rod 3, so as to avoid a large amount of weight relying entirely on the power mechanism 4 to move, so that the service life of the power mechanism 4 is reduced. Finally, the limiting plate 510 is used to limit the linkage frame 52 to prevent the front and rear sides of the linkage frame 52 from deflecting when the linkage frame 52 moves up and down, and the butterfly piece 58 is rotated to cause the screw 56 to rotate, so as to cause The top plate 55 and the clamping plate 57 release their clamping on the bottom frame 51, so that the linkage frame 52 can move up and down, and the rotating frame 53 is moved to the lowest side. The butterfly piece 58 is rotated again to fix the linkage frame 52 there, and the screw rod 56 is rotated to make the top plate 55 and the clamping plate 57 release their clamping on the bottom frame 51, and the top plate 55 is moved downward to cause the linkage frame 52 to move downward, and the rotating frame 53 to move downward, so that the rotating frame 53 and the first rotating wheel 54 jointly support the overall mass. When climbing stairs, the pull rod 3 is pulled to support the rotating frame 53 and the first rotating wheel 54 on the steps, thereby reducing the impact of the steps on the suitcase.

[0043] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
