Description

Technical Field

[0001] This utility model relates to the field of furniture, and in particular to a telescopic rod structure. Background Technology

[0002] Existing garment care machines have a telescopic rod structure.

[0003] For example, patent document CN213232874U discloses a telescopic tube structure and a garment care machine having the same structure. The telescopic tube structure includes a base; a telescopic tube vertically disposed within the base, which can partially extend beyond the base in an extended state; the telescopic tube is formed by at least two sleeves that can be telescopically connected, and a locking mechanism is provided between two adjacent sleeves to position them in an extended state; a positioning mechanism is disposed within the base, in which the lowermost sleeve is positioned by the positioning mechanism in the extended state of the telescopic tube, and there is a gap between the bottom end of the sleeve and the bottom wall of the base.

[0004] However, in the above-mentioned technologies, the telescopic rod structure is prone to slipping after it extends.

[0005] To address these technical problems, a telescopic rod structure is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a telescopic rod structure that has the advantages of not slipping after extension and strong stability.

[0007] The technical solution adopted by this utility model to solve the problem is: a telescopic rod structure, including: a rod body, the rod body including multiple tubes, the multiple tubes being slidably inserted in sequence, wherein the inner tube of two adjacent tubes is an inner tube, and the outer tube is a sleeve, and a limiting hole is opened on one side of the bottom end of the inner tube; it also includes a locking part, the locking part including a mounting seat, the mounting seat being fixedly sleeved on the top end of the sleeve, a handle being rotatably mounted on the mounting seat, a limiting block being fixedly provided on the inner side of the handle, and an avoidance hole being opened at the top end of the sleeve, wherein when the inner tube extends outward to the end, the avoidance hole, the limiting hole and the limiting block correspond to each other.

[0008] As a further improvement to the above technical solution, the locking part also includes a fixing seat, which is inserted and fixed to the top end of the sleeve, and the mounting seat is fixedly connected to the fixing seat.

[0009] As a further improvement to the above technical solution, fixing holes are provided on both sides of the bottom end of the inner tube, and a limiting member is provided at the bottom end of the inner tube. The limiting member is provided with a locking block, and the locking block engages with the fixing hole.

[0010] As a further improvement to the above technical solution, the top of the fixing seat is provided with a folded edge, which overlaps the top edge of the sleeve.

[0011] As a further improvement to the above technical solution, a first through hole is provided on one side of the top end of the sleeve, and a second through hole is provided on the mounting base. A fixing block is movably installed in the second through hole, and the fixing block extends into the first through hole and the second through hole and abuts against the fixing base.

[0012] As a further improvement to the above technical solution, a connecting post is fixedly installed on the handle, a rotating shaft is provided on the connecting post, two connecting ears are fixedly installed on the mounting base, the connecting post is located between the two connecting ears, and the rotating shaft is rotatably connected to the two connecting ears, and the fixing block is located between the two connecting ears.

[0013] The beneficial effects of this utility model are: by setting a locking part, the handle drives the limiting block to limit the inner tube, preventing the inner tube from extending to its maximum length and then sliding relative to the sleeve, thus ensuring strong stability.

[0024] Reference Figures 1 to 4 A telescopic rod structure includes: a rod body 1, which includes multiple tubes that are slidably connected in sequence, wherein the inner tube of two adjacent tubes is an inner tube 11 and the outer tube is a sleeve 12, and a limiting hole 111 is provided on one side of the bottom end of the inner tube 11; it also includes a locking part 2, which includes a mounting base 3, which is fixedly sleeved on the top end of the sleeve 12, and a handle 31 is rotatably mounted on the mounting base 3. A limiting block 32 is fixedly provided on the inner side of the handle 31, and an avoidance hole 121 is provided at the top end of the sleeve 12. When the inner tube 11 extends outward to the end, the avoidance hole 121, the limiting hole 111 and the limiting block 32 correspond to each other. When in use, the inner tube 11 is pulled outward, which can extend the rod 1. When the inner tube 11 extends to the end, the handle 31 is turned, which can cause the limiting block 32 to rotate through the clearance hole 121 and insert into the limiting hole 111, thereby restricting the relative sliding of the inner tube 11 and the sleeve 12. The rod 1 will not slip after it is extended, and the stability is strong.

[0025] In a preferred embodiment, the locking part 2 further includes a fixing seat 4, which is inserted and fixed to the top end of the sleeve 12, and the mounting seat 3 is fixedly connected to the fixing seat 4.

[0026] In a preferred embodiment, fixing holes 112 are provided on both sides of the bottom end of the inner tube 11, and a limiting member 113 is provided at the bottom end of the inner tube 11. A locking block 114 is provided on the limiting member 113, and the locking block 114 engages with the fixing hole 112. When the inner tube 11 is stretched upward to the end, the limiting member 113 abuts against the fixing seat 4, which can prevent the inner tube 11 from extending upward and disengaging from the sleeve 12.

[0027] In a preferred embodiment, the top of the fixing seat 4 is provided with a folded edge, which overlaps the top edge of the sleeve 12. This prevents the fixing seat 4 from falling into the sleeve 12.

[0028] In a preferred embodiment, a first through hole 122 is provided on one side of the top end of the sleeve 12, and a second through hole 33 is provided on the mounting base 3. A fixing block 34 is movably installed in the second through hole 33, extending into the first through hole 122 and the second through hole 33 and abutting against the mounting base 4. In use, the mounting base 4 is inserted into the sleeve 12, and the fixing block 34 is embedded in the first through hole 122 and the second through hole 33 and abuts against the mounting base 4, thereby allowing the mounting base 4 and the mounting base 3 to be installed, making assembly simple and convenient.

[0029] In a preferred embodiment, a connecting post 35 is fixedly mounted on the handle 31, and a rotating shaft 36 is provided on the connecting post 35. Two connecting ears 37 are fixedly mounted on the mounting base 3. The connecting post 35 is located between the two connecting ears 37, and the rotating shaft 36 is rotatably connected to the two connecting ears 37. A fixing block 34 is located between the two connecting ears 37. The fixing block 34 is limited by the connecting post 35 to prevent the fixing block 34 from disengaging from the mounting base 3, which facilitates assembly.

[0030] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
