Description

Technical Field

[0001] The utility model relates to the technical field of waterproof trolley cases, and more specifically, to a waterproof trolley case. Background Art

[0002] In the prior art, there are some defects in the design of waterproof trolley cases, which affect their waterproof performance and overall practicality.

[0003] Firstly, the structural design of many waterproof suitcases is relatively simple, which results in unsatisfactory waterproof effect. Although some suitcases are treated with waterproof coating on the surface of the case body and the case cover, this treatment often cannot completely prevent the penetration of moisture, especially at the connection between the case cover and the case body. Since zippers are usually used for connection, moisture can easily penetrate through the teeth of the zipper or the surface of the chain. This design defect makes the items stored in the suitcase at risk of getting wet, and cannot meet consumers' high requirements for waterproof performance.

[0004] Secondly, in the prior art, most waterproof trolley cases use zippers to close the case lid and the case body. However, the arrangement of the zippers and chain straps easily leads to an unstable overall structure. This instability may cause the case body and the case lid to be misaligned during use, thereby affecting the service life of the trolley case and the safety of the items. In addition, although some devices attempt to solve this problem by replacing the traditional zipper structure, these new structures are often difficult to disassemble and assemble, making the opening and closing operations between the case body and the case lid cumbersome, causing inconvenience to users.

[0005] In addition, although some devices in the prior art achieve quick connection and opening between the box body and the box cover while ensuring the stability of the overall structure, the structure of this mechanism is usually relatively simple, resulting in low stability. This simple design may lead to an unstable connection, resulting in loose connection or disconnection between the box body and the box cover during use, causing inconvenience and safety hazards to users.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the utility model provides a waterproof trolley case, which has the following beneficial effects:

[0019] 1. The beneficial effect of the waterproof device is mainly reflected in its effective waterproof performance. Through the arrangement of components such as the installation groove and the sealing strip, it can effectively prevent rainwater or other liquids from entering the box through the joints between the box body and the box cover. The elastic material and high elasticity of the sealing strip enable it to fit tightly with the installation groove and the sealing groove, thereby improving the overall waterproof effect. At the same time, the arrangement of the card block and the card slot ensures the stable installation of the sealing strip, making it difficult for the sealing strip to fall off or shift during use.

[0020] 2. The beneficial effect of the quick-connect device is reflected in its fast and easy connection and disassembly functions.

[0032] A moving wheel 22 is provided at the bottom of the box body 1 , and the moving wheel 22 can be movably installed on both sides of the box body 1 .

[0033] A telescopic sleeve 23 is detachably provided on one side of the box body 1 , and a telescopic rod 24 is movably provided inside the telescopic sleeve 23 .

[0034] A handle 25 is movably provided on the outer side of the box body 1, and a pull rod 26 is detachably provided on one end of the telescopic rod 24.

[0035] An annular groove 27 is provided in the quick-release sleeve 10 , and the annular groove 27 is opened on the outside of the clamping sleeve 11 .

[0036] A threaded sleeve 28 is disposed on one side of the push plate 14 , and the threaded sleeve 28 is detachably sleeved on the outer side of the quick-release sleeve 10 through threads.

[0037] In this embodiment, when the box cover 2 needs to be opened, the rotating sleeve 20 is first rotated in the corresponding direction, so that the rotating sleeve 20 drives the positioning rod 17 and the push spring 18 to move. When the position of the positioning rod 17 corresponds to the position of the clearance hole 21, the push plate 14 is pushed in the corresponding direction, the positioning rod 17 passes through the clearance hole 21, and the push plate 14 and the rotating sleeve 20 cooperate to squeeze the push spring 18, and then the push plate 14 drives the connecting rod 5 to slide along the sliding groove 7, and at the same time, the push plate 14 drives the unlocking sleeve 6 to move through the connecting rod 5, and then the unlocking sleeve 6 will gradually enter the annular groove 27. At the same time, due to the chamfered structural design of the inner wall of the unlocking sleeve 6 and the rounded structural design of one end of the clamping rod 13, the inner wall of the unlocking sleeve 6 will gradually press the clamping rod 13 into the movable groove 15, so that the clamping rod 13 is gradually collected in the movable groove 15 and squeezes the spring 12. At the same time, one side of the clamping rod 13 will no longer be engaged with one side of the clamping sleeve 11 through the parallel groove 16. Then the quick-release sleeve 10 can be pulled outward to remove the quick-release sleeve 10 from the outside of the quick-release rod 9, and then the box cover 2 can be opened. That is, when the box cover 2 needs to be fixed to one side of the box body 1, the box cover 2 is covered to one side of the box body 1, and then the quick-release sleeve 10 is fitted onto the outside of the quick-release rod 9. During the fitting process, one side of the clamping rod 13 is fitted with the slope 8. Due to the inclined structural design of the slope 8, the clamping rod 13 will be gradually pressed into the movable groove 15. At the same time, the clamping rod 13 will squeeze the spring 12 set on one side. When the outer side of the quick-release sleeve 10 is fitted onto the outer side of the quick-release rod 9, the push plate 14 is released, and the push spring 18 pushes the push plate 14 to reset, and then the push plate 14 is pushed back. The unlocking sleeve 6 is reset by the connecting rod 5, and then the outer side of the locking rod 13 loses the limit of the unlocking sleeve 6, and then the spring 12 pushes the locking rod 13 to reset, so that the locking rod 13 is engaged with one side of the locking sleeve 11 through the parallel groove 16, and then the rotating sleeve 20 is rotated, so that the rotating sleeve 20 drives the positioning rod 17 to push the spring 18 to move, and then the position of the positioning rod 17 and the clearance hole 21 no longer correspond, so that the positioning rod 17 forms a stable support for the push plate 14, thereby effectively preventing the push plate 14 from moving, thereby ensuring the stability of the connecting structure.

[0038] See also Figure 1 and Figure 3 As an implementation of the waterproof device: the waterproof device includes a mounting groove 29, a sealing strip 30 and a sealing groove 31, the mounting groove 29 is opened in the box body 1, the sealing strip 30 is detachably installed in the mounting groove 29, the sealing groove 31 is opened on the inner side of the box cover 2, and one side of the sealing strip 30 is adapted to the sealing groove 31.

[0039] A clamping block 32 is disposed in the installation groove 29 , and clamping grooves 33 are correspondingly provided on both sides of the sealing strip 30 , and the clamping block 32 is adapted to fit into the clamping grooves 33 .

[0040] More specifically, when the pull rod 26 box is needed, the box body 1 and the box cover 2 can be directly pulled by the handle 25 to make them move through the moving wheels 22, or the box body 1 and the box cover 2 can be directly lifted and carried by the handle 25, and the telescopic rod 24 can be pulled out from the telescopic sleeve 23 by the pull rod 26, and then the box body 1 and the box cover 2 are pulled by the pull rod 26 to make them move through the moving wheels 22. The box body 1 and the box cover 2 are made of waterproof material, which can effectively improve the waterproof performance. At the same time, the sealing strip 30 and the sealing groove 31 installed in the installation groove 29 can effectively prevent rainwater from entering the inside of the box body 1 and the box cover 2 from the joints. The setting of the card slot 33 and the card block 32 ensures the stable installation of the sealing strip 30. At the same time, since the sealing strip 30 is made of highly elastic material, the sealing strip 30 can also be conveniently taken out of the installation groove 29 for replacement, thereby further improving the overall waterproof performance of the pull rod 26 box.

[0041] In summary, when the overall device is in use or running: when the box cover 2 needs to be opened, the rotating sleeve 20 is first rotated in the corresponding direction, so that the rotating sleeve 20 drives the positioning rod 17 and the push spring 18 to move. When the position of the positioning rod 17 corresponds to the position of the clearance hole 21, the push plate 14 is pushed in the corresponding direction, the positioning rod 17 will pass through the clearance hole 21, and the push plate 14 will cooperate with the rotating sleeve 20 to squeeze the push spring 18, and then the push plate 14 will drive the connecting rod 5 to slide along the sliding groove 7, and at the same time, the push plate 14 drives the unlocking sleeve 6 to move through the connecting rod 5. The unlocking sleeve 6 is moved, and then one end of the unlocking sleeve 6 will gradually enter the annular groove 27. At the same time, due to the chamfered structural design of the inner wall of the unlocking sleeve 6 and the rounded structural design of one end of the clamping rod 13, the inner wall of the unlocking sleeve 6 will gradually press the clamping rod 13 into the movable groove 15, so that the clamping rod 13 is gradually collected in the movable groove 15 and squeezes the spring 12. At the same time, one side of the clamping rod 13 will no longer be engaged with one side of the clamping sleeve 11 through the parallel groove 16. Then the quick-release sleeve 10 can be pulled outward to remove the quick-release sleeve 10 from the outside of the quick-release rod 9, and then the box can be removed. The cover 2 can be opened. When the box cover 2 needs to be fixed to one side of the box body 1, the box cover 2 is covered to one side of the box body 1, and then the quick-release sleeve 10 is fitted to the outside of the quick-release rod 9. During the fitting process, one side of the clamping rod 13 is fitted with the slope 8. Due to the inclined structural design of the slope 8, the clamping rod 13 will be gradually pressed into the movable groove 15. At the same time, the clamping rod 13 will squeeze the spring 12 set on one side. When the outer side of the quick-release sleeve 10 is fitted to the outer side of the quick-release rod 9, the push plate 14 is released, and the push spring 18 pushes the push plate 14 to reset, and then the push plate 14 drives the unlocking sleeve 6 to reset through the connecting rod 5, and then the outer side of the locking rod 13 loses the limit of the unlocking sleeve 6, and then the spring 12 pushes the locking rod 13 to reset, so that the locking rod 13 is engaged with one side of the locking sleeve 11 through the parallel groove 16, and then the rotating sleeve 20 is rotated, so that the rotating sleeve 20 drives the positioning rod 17 to push the spring 18 to move, and then the position of the positioning rod 17 and the clearance hole 21 no longer correspond, so that the positioning rod 17 forms a stable support for the push plate 14, thereby effectively preventing the push plate 14 from moving, thereby ensuring the stability of the connecting structure.

[0042] When the pull rod 26 box is needed, the box body 1 and the box cover 2 can be directly pulled by the handle 25 to make them move through the moving wheels 22, or the box body 1 and the box cover 2 can be directly lifted and carried by the handle 25. At the same time, the telescopic rod 24 can be pulled out from the telescopic sleeve 23 by the pull rod 26, and then the box body 1 and the box cover 2 are pulled by the pull rod 26 to make them move through the moving wheels 22. The box body 1 and the box cover 2 are made of waterproof material, which can effectively improve the waterproof performance. At the same time, the sealing strip 30 and the sealing groove 31 installed in the installation groove 29 can effectively prevent rainwater from entering the inside of the box body 1 and the box cover 2 from the joints. The setting of the card slot 33 and the card block 32 ensures the stable installation of the sealing strip 30. At the same time, since the sealing strip 30 is made of highly elastic material, the sealing strip 30 can also be conveniently taken out of the installation groove 29 for replacement, thereby further improving the overall waterproof performance of the pull rod 26 box.
