Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a luggage anti-slip device, solving the problems mentioned in the background section. To achieve the above objectives, this utility model is implemented through the following technical solution: a luggage anti-slip device, comprising a luggage body, wherein the bottom of the luggage body is equipped with casters, and the top of the luggage body is equipped with a pull rod;

[0005] The bottom of the suitcase body is provided with an anti-slip component, which includes an arc-shaped compartment and a hydraulic compartment. The arc-shaped compartment contains a gravity ball. One end of the hydraulic compartment is slidably connected to a sensor block, and the other end of the hydraulic compartment is slidably connected to a locking rod. The bottom of the sensor block is fixedly connected to a spring. The bottom of the suitcase body is connected to a sleeve through a strong spring. The side of the sleeve has a locking groove, and the bottom of the sleeve is fixedly connected to a limit plate.

[0006] Preferably, the end of the spring away from the sensing block is fixedly connected to the inner wall of the hydraulic chamber, so that the sensing block can be reset under the action of the spring when no force is applied.

[0007] Preferably, the slot is located on the side of the lever, and the cross-sectional shape of the slot is adapted to the lever, so that the lever can restrict the device when it is in the slot.

[0008] Preferably, an auxiliary component is provided on the side of the suitcase body. The auxiliary component includes a hydraulic compartment two, a pressure rod is slidably connected to the top of the hydraulic compartment two, a baffle is rotatably connected to the inner wall of the hydraulic compartment two, and an elastic rod is fixedly connected to the side of the baffle.

[0009] Preferably, the second hydraulic chamber is located on the side of the first hydraulic chamber, and the second hydraulic chamber is fixedly connected to and communicates with the first hydraulic chamber.

[0010] Preferably, there are two elastic rods, which are symmetrically distributed about the baffle, so that the baffle is subjected to a more uniform force from the elastic rods.

[0011] This utility model provides an anti-slip device for suitcases. It has the following beneficial effects:

[0012] (1) When the luggage body is on an inclined plane, the gravity ball in the arc-shaped compartment moves under the action of gravity. In conjunction with the sensing block, spring one, hydraulic compartment one, lever, sleeve, slot, sleeve and strong spring two, the limiting plate moves to the inclined plane to prevent slipping. No manual operation is required, and the anti-slip effect of the device is improved.

[0013] (2) When the luggage body is used on an inclined plane, the user pulls the lever with his palm to move the luggage body. At this time, the pressure bar on the lever is squeezed by the palm and moves, which increases the pressure in the hydraulic chamber 2. Under the action of this pressure, the baffle in the hydraulic chamber 2 squeezes the elastic rod and rotates. Since the hydraulic chamber 2 is connected to the hydraulic chamber 1, the pressure is then passed into the hydraulic chamber 1 and applied to the locking rod. Therefore, when the sensing block loses its restriction, it will not drive the locking rod to move, making the device easier to use. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0024] Please see Figures 1-5 A luggage anti-slip device includes a luggage body 100, a universal wheel 200 mounted on the bottom of the luggage body 100, and a pull rod 300 mounted on the top of the luggage body 100.

[0025] The bottom of the suitcase body 100 is provided with an anti-slip component 400, which includes an arc-shaped compartment 401 and a hydraulic compartment 402. A gravity ball 403 is provided inside the arc-shaped compartment 401. A sensor block 404 is slidably connected to one end of the hydraulic compartment 402, and a lever 405 is slidably connected to the other end of the hydraulic compartment 402. A spring 406 is fixedly connected to the bottom of the sensor block 404. The end of the spring 406 away from the sensor block 404 is fixedly connected to the inner wall of the hydraulic compartment 402. When the suitcase body 100 is on an inclined plane, the gravity ball 403 inside the arc-shaped compartment 401 moves under the action of gravity. The gravity ball 403 moves away from the sensing block 404, causing the sensing block 404 to move upward under the action of the spring 406. This, in conjunction with the hydraulic compartment 402 slidably connected to the sensing block 404, reduces the pressure inside the hydraulic compartment 402, thereby moving the locking rod 405 slidably connected to the hydraulic compartment 402. A sleeve 408 is connected to the bottom of the suitcase body 100 via a strong spring 407. A slot 409 is provided on the side of the sleeve 408, located on the side of the locking rod 405. The cross-sectional shape of the slot 409 is adapted to the locking rod 405. A limit plate 410 is fixedly connected to the bottom of the sleeve 408. When the locking rod 405 moves out of the slot 409 on the sleeve 408, the sleeve 408 is no longer restricted. The sleeve 408 is then moved towards the inclined plane by the force of the strong spring 407 fixedly connected to it, so as to prevent slipping. No manual operation is required, and the anti-slip effect of the device is improved.

[0026] When in use, when the suitcase body 100 is on an inclined plane, the gravity ball 403 inside the arc-shaped compartment 401 moves under the action of gravity. The gravity ball 403 moves away from the sensing block 404, causing the sensing block 404 to move upward under the action of the spring 406. In conjunction with the hydraulic compartment 402 slidably connected to the sensing block 404, the pressure inside the hydraulic compartment 402 decreases, thereby driving the locking rod 405 slidably connected to the hydraulic compartment 402 to move. The locking rod 405 moves out of the slot 409 on the sleeve 408, thereby causing the sleeve 408 to lose its restraint. The sleeve 408 is then driven by the strong spring 407 fixedly connected to it to move the limiting plate 410 fixedly connected to the sleeve 408 towards the inclined plane for anti-slip. Example

[0027] Please see Figures 1-5Based on Embodiment 1, an auxiliary component 500 is provided on the side of the suitcase body 100. The auxiliary component 500 includes a second hydraulic compartment 501, which is located to the side of the first hydraulic compartment 402. The second hydraulic compartment 501 is fixedly connected to and communicates with the first hydraulic compartment 402. A pressure rod 502 is slidably connected to the top of the second hydraulic compartment 501. When using the suitcase body 100 on an inclined plane, the user pulls the pull rod 300 with their palm to move the suitcase body 100. At this time, the pressure rod 502 on the pull rod 300 moves due to the pressure of the palm. A baffle 503 is rotatably connected to the inner wall of the second hydraulic compartment 501. An elastic rod 504 is fixedly connected to the side of the baffle 503. There are two elastic rods 504, which are symmetrically distributed about the baffle 503. When the pressure rod 502 moves, the pressure inside the hydraulic chamber 2 501, which is slidably connected to the pressure rod 502, increases. Under the action of this pressure, the baffle 503 inside the hydraulic chamber 2 501 squeezes the elastic rod 504 and causes it to rotate. Since the hydraulic chamber 2 501 is connected to the hydraulic chamber 1 402, the pressure is then introduced into the hydraulic chamber 1 402 and applied to the locking rod 405. As a result, when the sensing block 404 is no longer restricted, it will not cause the locking rod 405 to move. When anti-slip is not required, the limiting plate 410 will not move, making the device easier to use.

[0028] In use, based on Embodiment 1, when using the suitcase body 100 on an inclined plane, the user pulls the lever 300 with their palm to move the suitcase body 100. At this time, the pressure bar 502 on the lever 300 moves due to the pressure of the palm, which increases the pressure in the hydraulic chamber 2 501 that is slidably connected to the pressure bar 502. Under the action of this pressure, the baffle 503 in the hydraulic chamber 2 501 squeezes the elastic rod 504 and rotates. Since the hydraulic chamber 2 501 is connected to the hydraulic chamber 1 402, the pressure is then introduced into the hydraulic chamber 1 402 and applied to the locking rod 405. Therefore, when the sensing block 404 is no longer restricted, it will not move the locking rod 405.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
