Description

Technical Field

[0001] This utility model relates to the field of luggage accessories technology, specifically to a detachable luggage wheel seat. Background Technology

[0002] With the continuous improvement of people's living standards and consumption levels, various kinds of bags have become indispensable items in people's lives. Suitcases are commonly used items for people traveling or on business trips. In order to save energy during long journeys, people generally choose wheeled suitcases to carry their luggage. This is because wheeled suitcases not only have a large capacity to hold items, but also have wheels on the bottom and a handle on the body, allowing users to freely drag the suitcase. This makes them not only convenient to carry, but also saves time and effort.

[0003] Currently, most swivel casters on the market use fasteners between the wheel base and the wheel frame to allow the wheel frame to rotate around the wheel base. However, the fastener connection structure requires each screw to be unscrewed or inserted during disassembly and assembly, making the process cumbersome and inefficient. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a detachable bag wheel seat that is easy to assemble and disassemble and improves efficiency, in order to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable luggage wheel seat, comprising a housing and a connector detachably connected to the housing and mounted on a wheel frame, wherein the housing is provided with an mounting hole for mounting the connector, characterized in that: an annular groove is provided on the outer wall of one end of the connector, and a toggle switch is provided on the side of the housing located at the mounting hole, wherein the toggle switch is linked to a locking structure that can engage with the annular groove and cause the connector to be fixed in the mounting hole.

[0006] Using the above technical solution: During use, when installation is required, simply insert the connector into the mounting hole, then slide the toggle switch to engage the locking structure with the annular groove on the connector, thus fixing the connector in the mounting hole and completing the installation. When disassembly is required, simply slide the toggle switch in the opposite direction to disengage the locking structure from the annular groove. Once the force fixing the annular groove disappears, the connector can be removed, thus facilitating disassembly and improving disassembly and assembly efficiency.

[0007] A further feature of this invention is that the locking structure includes a linkage component that is linked to the toggle switch. The linkage component has symmetrically arranged locking blocks that can engage with the annular slot at one end near the connector, and a locking space is formed between the locking blocks for the connector to slide into. The locking blocks can abut against the upper surface of the annular slot.

[0008] The above technical solution is adopted as follows: by setting the locking block on the linkage, when locked, the toggle switch drives the linkage to move towards the connector, so that the connector enters the locking space. At the same time, the locking blocks on both sides are located in the annular slot. At this time, the upper end of the annular slot abuts against the locking block, realizing the locking and thus enabling the connector to be fixed in the mounting hole.

[0009] A further feature of this invention is that: sliding blocks extend upward from both sides of the toggle switch; first sliding grooves for sliding blocks to slide are provided on both sides of the linkage member; a first limiting block is provided on the first sliding groove; a second limiting block that can abut against the first limiting block is provided on one side of the sliding block opposite to the first sliding groove; a locking member is provided on the other side of the sliding block; and a locking groove that engages with the locking member is provided on the housing.

[0010] The above technical solution employs a toggle switch that allows the linkage to move up and down. During unlocking, pressing the toggle switch causes the sliding block on it to move upwards along the first sliding groove, disengaging the locking element from the locking groove. Only then can the toggle switch be slid to unlock. Conversely, to lock, the toggle switch is slid in the opposite direction. When slid to a certain position, the locking element, along with the sliding block moved by the linkage, falls into the locking groove. At this point, the locking block engages with the annular locking groove. This locking element and locking groove configuration further strengthens the locked state structure, preventing the toggle switch from sliding due to vibration while the suitcase is in motion, thus avoiding self-unlocking. Simultaneously, the first and second limit blocks prevent the toggle switch from falling out.

[0011] A further feature of this invention is that: the upper end face of the toggle switch located between the sliding blocks has a first spring cavity, the lower end face of the linkage member has a second spring cavity opposite to the first spring cavity, and a first spring is provided between the first spring cavity and the second spring cavity. A guide post is provided in the middle of the first spring cavity, and the first spring is arranged around the guide post.

[0012] The above technical solution is adopted as follows: By setting the first spring, when unlocking is required, the toggle switch is pressed and slid, at which time the first spring is compressed and elastic potential energy is stored. When locking, when the locking part moves to the locking groove position, the elastic potential energy stored in the first spring is released, which drives the locking part to reset into the locking groove, thus completing the locking.

[0013] A further feature of this invention is that the upper surface of the linkage component extends upward on both sides of the first sliding groove and is provided with abutting blocks that can abut against the sliding blocks.

[0014] The above technical solution is adopted: by setting the abutment block, when the toggle switch is pressed and the sliding block moves upward along the first sliding groove, the sliding block can abut against the abutment block, thereby ensuring that even after the sliding block moves upward, the sliding block can still drive the linkage to move through the abutment block when the toggle switch is slid, while preventing the sliding block from shifting position.

[0015] A further feature of this invention is that: the lower end face of the housing is provided with a toggle groove for sliding the toggle switch, and the upper end face of the housing is provided with a second sliding groove for sliding the linkage component, the second sliding groove communicating with the mounting hole.

[0016] By adopting the above technical solution, the use effect of the toggle switch and the linkage can be guaranteed by setting the toggle groove and the second sliding groove.

[0017] A further feature of this invention is that: an installation groove is provided on the upper surface of the other end of the linkage component away from the connector; a spring seat is provided on the end of the installation groove near the connector; a second spring is provided in the installation groove; one end of the second spring abuts against the spring seat; and the other end abuts against the inner wall of the housing.

[0018] The above technical solution is adopted as follows: By setting the second spring, when the connecting part is installed after the sliding toggle switch is unlocked, the toggle switch drives the linkage to move away from the connecting part. At this time, the second spring is compressed and the elastic potential energy is stored. When the user releases the sliding toggle switch, the second spring will drive the toggle switch to reset, which can prevent the user from forgetting the switch status and failing to lock the wheel seat and the connecting part.

[0019] A further feature of this invention is that the housing is detachably connected to a cover plate above the linkage component via fasteners, and the cover plate can cover the second spring.

[0020] The above technical solution aims to prevent foreign objects from entering and affecting the performance of the second spring or linkage components by using a cover plate.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0031] In the accompanying drawings of this specific embodiment and the disclosed embodiments, only the structures involved in the disclosed embodiments are involved. Other structures can be referred to with ordinary design. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of this utility model, they are protected by patent law.

[0032] Example 1:

[0033] like Figure 1-7 The detachable luggage wheel seat shown includes a housing 1 and a connector 2 detachably connected to the housing 1 and mounted on a wheel frame. The housing 1 has a mounting hole 11 for mounting the connector 2. One end of the outer wall of the connector 2 has an annular groove 21. The housing 1 has a toggle switch 3 on the side of the mounting hole 11. The toggle switch 3 is linked to a locking structure 4 that can engage with the annular groove 21 and fix the connector 2 in the mounting hole 11.

[0034] like Figure 2-5 The locking structure 4 shown includes a linkage member 41 that is linked with the toggle switch 3. The linkage member 41 has symmetrically arranged locking blocks 411 that can engage with the annular slot 21 at one end near the connector 2. A locking space 412 is formed between the locking blocks 411 for the connector 2 to slide into. The locking blocks 411 can abut against the upper surface of the annular slot 21.

[0035] like Figure 3-5The toggle switch 3 shown has sliding blocks 31 extending upward on both sides. The linkage 41 has first sliding grooves 413 on both sides for the sliding blocks 31 to slide. The first sliding groove 413 has a first limiting block 413a. The sliding block 31 has a second limiting block 311 on one side opposite to the first sliding groove 413, which can abut against the first limiting block 413a. The other side of the sliding block 31 has a locking member 312. The housing 1 has a locking groove 12 that engages with the locking member 312.

[0036] like Figure 4-5 The toggle switch 3 shown has a first spring cavity 32 on its upper end face between the sliding blocks 31. The lower end face of the linkage 41 has a second spring cavity 42 opposite to the first spring cavity 32. A first spring 321 is provided between the first spring cavity 32 and the second spring cavity 42. A guide post 322 is provided in the middle of the first spring cavity 32. The first spring 321 is arranged around the guide post 322.

[0037] like Figure 6-7 The upper end face of the linkage 41 shown is provided with abutment blocks 43 extending upward on both sides of the first sliding groove 413, which can abut against the sliding block 31; the lower end face of the housing 1 is provided with a toggle groove 13 for the toggle switch 3 to slide, and the upper end face of the housing 1 is provided with a second sliding groove 14 for the linkage 41 to slide, and the second sliding groove 14 communicates with the mounting hole 11.

[0038] During use, when installation is required, the toggle switch 3 is in the unlocked state. At this time, the linkage 41 is away from the mounting hole 11, and the connector 2 is inserted into the mounting hole 11. Sliding the toggle switch 3 drives the linkage 41 to move closer to the connector 2, so that the connector 2 enters the engaging space 412. At the same time, the locking blocks 411 on both sides of the linkage 41 are located in the annular locking groove 21. At this time, the upper end surface of the annular locking groove 21 abuts against the locking block 411, realizing the engagement and thus enabling the connector 2 to be fixed in the mounting hole 11. When disassembly is required, pressing the toggle switch 3 causes the sliding block 31 on the toggle switch 3 to move upward along the first sliding groove 413, so that the locking member 312 can disengage from the locking groove 12, and then the toggle switch 3 can be slid to unlock, further improving the stability of the locking.

[0039] Example 2:

[0040] like Figure 1 , 8As shown, the structure of Embodiment 2 is basically the same as that of Embodiment 1. The difference is that the upper surface of the other end of the linkage 41 away from the connector 2 is provided with a mounting groove 44. A spring seat 441 is provided on the end of the mounting groove 44 near the connector 2. A second spring 442 is provided in the mounting groove 44. One end of the second spring 442 abuts against the spring seat 441, and the other end abuts against the inner wall of the housing 1. A cover plate 15 is detachably connected to the housing 1 above the linkage 41 by fasteners. The cover plate 15 can cover the second spring 442.

[0041] In use, the user first presses the toggle switch 3 to disengage the locking member 312 from the locking groove 12, then slides the toggle switch to unlock it. Next, the connecting member 2 is inserted into the mounting hole 11. At this time, the user's hand cannot release the toggle switch. Simultaneously, as the toggle switch 3 drives the linkage member 41 to move away from the connecting member 2, the second spring 442 is compressed, and elastic potential energy is stored. When the user releases the sliding toggle switch 3, the second spring 442 will drive the toggle switch 3 to reset, which can prevent the user from forgetting the switch state and failing to lock the wheel seat and the connecting member 2.
