When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
[0032] This utility model proposes a basket retraction and extension linkage mechanism 1.
[0033] In this embodiment of the utility model, such as Figures 1 to 6 As shown, the retraction linkage mechanism 1 includes a first connector 11, a second connector 12, and a locking mechanism 13 for locking and unlocking the first connector 11 and the second connector 12. The first end of the first connector 11 is pivotally connected to the upper enclosure tube 221, and the first end of the second connector 12 is pivotally connected to the lower enclosure tube 222. The second ends of the first connector 11 and the second ends of the second connector 12 are pivotally connected. The locking mechanism 13 is disposed between the second ends of the first connector 11 and the second ends of the second connector 12. When the first connector 11 and the second connector 12 are locked by the locking mechanism 13, the basket retraction is locked. When the first connector 11 and the second connector 12 are unlocked by the locking mechanism 13, the retraction linkage mechanism 1 can retract and extend the basket in conjunction.
[0034] In some embodiments of this utility model, the locking mechanism 13 includes a handle 131, a first connector 11 and a second connector 12 that overlap at least partially, and the handle 131 can move between the overlapping portion and the position away from the overlapping portion. When the handle 131 is in the position of the overlapping portion, the first connector 11 and the second connector 12 are locked and relative rotation is not allowed. When the handle 131 is in the position of the overlapping portion, the first connector 11 and the second connector 12 are unlocked and relative rotation is allowed.
[0035] Specifically, the locking mechanism 13 also includes a first limiting member 132 for preventing the pull handle 131 from sliding down. The first limiting member 132 is located at the position of the first connector 11 corresponding to the bottom end of the pull handle 131. Preferably, in order to produce a stable limiting effect, the first limiting member 132 is integrally formed on the first connector 11.
[0036] Specifically, the handle 131 includes a body, a first receiving chamber 1311 disposed inside the body, and a second receiving chamber 1312. The first receiving chamber 1311 is used for the first connector 11 to be sleeved, and the second receiving chamber 1312 is used for the second connector 12 to be sleeved.
[0037] Specifically, a wrench 1315 is provided on the outer side of the handle 131 body. The main purpose of providing the wrench 1315 is to provide a better grip and ease of operation. In addition, the wrench 1315 can increase the contact area of the user's fingers, making it more stable and comfortable for the user to operate the handle 131.
[0038] Specifically, the pull handle 131 also includes a third receiving chamber 1313 located inside the body. The third receiving chamber 1313 is provided with a reset component (not shown). The locking mechanism 13 also includes a second limiting member 133 for limiting the ejection of the reset component. The second limiting member 133 is located at the top end of the first connecting member 11 corresponding to the pull handle 131.
[0039] Specifically, the reset component is preferably a spring. In some other embodiments, the reset component can also be replaced by common components with certain elastic functions such as rubber, sponge, silicone, and fiber. This is prior art and will not be described in detail.
[0040] In some embodiments of this utility model, the locking mechanism 13 further includes a third limiting member 134 disposed on the second connecting member 12. The third limiting member 134 is used to restrict the first connecting member 11 from moving in a non-predetermined direction. In order to conform to daily operating habits during the closing process, in some preferred embodiments, the rotation direction of the first connecting member 11 is limited to a fixed direction. The third limiting member 134 is provided on the second connecting member 12 to prevent the first connecting member 11 from rotating in the opposite direction, thereby avoiding the first connecting member 11 from falling into an abnormal working state and affecting the closing process.
[0041] In some embodiments of this utility model, the second connector 12 is formed with a bent structure, including a first bent portion 121 and a second bent portion 122. The first connector 11 is mated to the first bent portion 121. The function of the first bent portion 121 and the second bent portion 122 is to make the rotation of the first connector 11 around the hinge point of the second connector 12 smoother. In order to further improve the rotation effect of the first connector 11, in some preferred embodiments of this utility model, the second connector 12 is bent in the opposite direction of the rotation of the first connector 11.
[0042] This utility model also proposes a retractable basket 2, such as Figure 1 and Figure 6As shown, the retractable basket 2 includes the aforementioned retractable linkage mechanism 1, handle 21, basket body 22, and support assembly 23. The basket body 22 includes the aforementioned upper surrounding tube 221 and lower surrounding tube 222. The handle 21 is pivotally connected to the basket body 22. The first end of the support assembly 23 is pivotally connected to the upper surrounding tube 221, and the other end is pivotally connected to the lower surrounding tube 222. The structure of the retractable linkage mechanism 1 is as described in the above embodiment. Since this retractable basket 2 adopts all the technical solutions of all embodiments of the retractable linkage mechanism 1 described above, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.
[0043] Specifically, the retractable basket 2 also includes a sliding joint seat 24 and / or a fixed joint seat 25. The first connector 11, the second connector 12, and the support assembly 23 are pivotally connected to the upper enclosure tube 221 and the lower enclosure tube 222 respectively through the corresponding sliding joint seat 24 and / or fixed joint seat 25. Preferably, in order to save assembly, in the actual assembly of the retractable basket 2, only one fixed joint seat 25 is required to achieve the basic purpose of use.
[0044] Specifically, in order to improve the efficiency of folding by moving the support component 23 installed on the retractable basket 2 synchronously, a linkage 26 for coordinating the folding and unfolding of the support component 23 is provided between the parallel sliding joint seats 24 on opposite sides.
[0045] Understandably, when it is necessary to unfold the retractable basket 2, lifting the handle 21 will return the retractable basket 2 to the unfolded state, at which time the aforementioned unfolding linkage mechanism 1 will snap back to its initial position.
[0046] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
