Description
Technical Field
[0001] The utility model relates to the technical field of trolley cases, in particular to a horizontal trolley case. Background Art
[0002] A trolley case refers to a suitcase with a handle and wheels. It is widely used because of its convenience. At the same time, trolley cases are also divided into single-tube trolleys and double-tube trolleys because the case has a trolley. The tube of the trolley is also divided into square tubes and round tubes, which makes it easy to drag while walking and greatly reduces the burden.
[0003] However, the following problems still exist in actual use:
[0004] Most of the existing trolley cases are placed vertically, which makes the trolley cases less stable. When affected by external forces, they are prone to tipping over, causing damage to items inside the case. At the same time, the height of the existing trolley case wheels cannot be adjusted as needed, which makes the case prone to slipping when it is stationary, and on rugged roads, the bottom of the case is prone to friction with the ground, damaging the case. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides a horizontal trolley case, which can effectively solve the problem of poor stability of vertical trolley cases and can adjust the height of the running wheels according to needs, thereby solving the problems raised in the background technology.
[0006] The utility model provides the following technical solution: a horizontal trolley case comprises: a base, a bearing plate is movably connected to the inside of the base, two limiting circular grooves are provided on the inner lower surface of the base, a screw is rotatably sleeved inside the two limiting circular grooves, a limiting circular groove is provided on the inside of the bearing plate, a limiting circular block is rotatably sleeved inside the one limiting circular groove, the inside of the limiting circular block is threadedly connected to the outer surface of the screw, an inner groove is provided on the inner lower surface of the screw, an adjusting rod is movably connected to the inside of the inner groove, clamping blocks are fixedly connected to the outer surfaces of the end portions of the adjusting rod, clamping grooves are provided on both sides of the inner groove, and the outer surfaces of the clamping blocks are clamped to the inside of the clamping grooves.
[0007] Preferably, the four corners of the base are movably connected with running wheels, and the four corners of the lower surface of the supporting plate are connected with running wheels.
[0008] Preferably, U-shaped blocks are fixedly connected to both sides of the inner lower surface of the base, a rotating shaft is rotatably connected to the inside of the U-shaped block, and a support plate is fixedly connected to the inside of the rotating shaft.
[0009] Preferably, both sides of the lower surface of the supporting plate are provided with sliding grooves, the interior of the sliding groove is slidably connected with a slider, the lower surface of the slider is fixedly connected with a U-shaped block, the interior of the U-shaped block is rotatably connected with a rotating shaft, and the outer surface of the rotating shaft is fixedly connected with a support plate.
[0010] Preferably, the upper surface of the base is connected to a box body, and a connecting fabric is provided in the middle of the box body.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. For this type of horizontal trolley case, when adjusting the height of the running wheel, firstly, since the outer surface of the adjusting rod is movably connected to the inside of the inner groove, and the outer surfaces of the ends of the adjusting rod are connected with blocks on both sides, the adjusting rod is rotated and pulled downward, so that the blocks arranged at the ends of the adjusting rod are clamped in the inside of the clamping groove. At the same time, since the outer surface of the screw is threadedly connected to the limiting round block, and the limiting round block is rotatably sleeved with the bearing plate through the limiting round groove, the screw is driven to rotate by rotating the adjusting rod, and the screw drives the limiting round block to rotate, so that the limiting round block moves up and down on the outer surface of the screw, and the synchronous bearing plate moves up and down inside the base, so that the running wheels arranged at the four corners of the lower surface of the bearing plate can move synchronously. The travel wheel is gradually retracted into the range of the base when the vehicle moves upward, so that the base can be supported on the ground and the overall device can be prevented from sliding. When the vehicle moves downward, the height of the travel wheel is increased, so that the bottom of the base can be increased away from the ground to avoid the bottom of the base rubbing against the ground when moving, causing wear on the bottom of the base. The arrangement of this structure can effectively improve the protection of the surface of the base and prevent slipping when the vehicle is stationary. At the same time, when the load-bearing plate moves up and down, the U-shaped blocks, rotating shafts, support plates and other components arranged on the opposite sides of the load-bearing plate and the base form an auxiliary support mechanism, thereby ensuring the stability of the load-bearing plate when moving.
[0013] 2. This type of horizontal trolley case, by changing the existing vertical trolley case into a horizontal trolley case as shown in the figure, can effectively prevent the items inside the device from being squeezed against each other, while increasing the capacity of the box body and the distance between each running wheel, thereby ensuring its stability during movement.
