[0005] The present invention provides a quick installation structure for the handle of the base, including a handle rubber, a handle card seat inserted into the handle rubber, and a transmission rod snap-fitted and fixed into the handle card seat. The handle rubber and the handle card seat, and the handle card seat and the transmission rod are both assembled by snap-fastening structures through snap-fitting; there are 2 corresponding card slots and 2 corresponding card strips on the handle card seat, a card block protrudes outward from the card strip, the outer side surface of the card block is an inclined surface, a hollow cylindrical groove adapted to the handle card seat is provided in the handle rubber, a convex strip adapted to the card slot is provided on the inner side wall of the hollow cylindrical groove, a groove adapted to the card strip is provided on the inner side wall of the hollow cylindrical groove, and a snap hole that can be snap-fastened with the card block of the card strip is provided at the end of the groove; during assembly, the transmission rod is snap-inserted into the handle card seat and snap-fixed, and then the handle card seat is snap-inserted into the hollow cylindrical groove of the handle rubber. When snap-inserting, the card slot of the handle card seat corresponds to the convex strip for positioning, the card strip of the handle card seat corresponds to the groove, and when snap-inserted until the card block snaps into the snap hole.

[0006] Preferably, a plurality of snap-fit strips are provided on the outer side of the transmission rod, and a snap-fit groove corresponding to and adapted to the snap-fit strips and capable of being snap-fastened is provided on the inner side wall of the handle card seat.

[0007] The present invention realizes a quick installation structure for the handle of a base, which has a simple and scientific structure, a split design, can be quickly installed, is easy to assemble, requires a small packaging volume, reduces packaging materials, lowers packaging costs and transportation and storage costs, is convenient for maintenance and replacement, and effectively extends the service life of the product.

[0015] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0016] Referring to Figures 1 to 6 , an embodiment of the quick installation structure for the handle of the base of the present invention is proposed, which includes a handle rubber 101, a handle card seat 102 installed in the handle rubber 101, and a transmission rod 103 inserted and fixed in the handle card seat 102. The handle rubber 101 and the handle card seat 102, and the handle card seat 102 and the transmission rod 103 are both assembled by snap structures.

[0017] The handle base 102 is provided with 2 corresponding card slots 104 and 2 corresponding card strips 105. The card strip 105 protrudes outwardly with a locking block 106. The outer side surface of the locking block 106 is an inclined surface. The handle rubber 101 is provided with a hollow cylindrical groove adapted to the handle base 102. The inner side wall of the hollow cylindrical groove is provided with a rib 107 adapted to the card slot 104. The rib 107 and the card slot 104 are mutually engaged to play a positioning role. The inner side wall of the hollow cylindrical groove is provided with a groove 108 adapted to the card strip 105. At the end of the groove 108, there is a snap hole 109 that can be snap-fixed to the locking block 106 of the card strip 105.

[0018] The transmission rod 103 is provided with a plurality of engaging strips 110 outwardly. The inner side wall of the handle base 102 is provided with an engaging groove corresponding to and adapted to the engaging strips 110 and capable of being snap-fixed.

[0019] During assembly, the transmission rod 103 is inserted into the handle base 102 and snap-fixed. Then, the handle base 102 is inserted into the hollow cylindrical groove of the handle rubber 101. During insertion, the card slot 104 of the handle base 102 corresponds to the rib 107 for positioning, and the card strip 105 of the handle base 102 corresponds to the groove 108. It is okay when the locking block 106 is snapped into the snap hole 109. Such a structure is scientific and simple. Installation can be completed without using tools such as screwdrivers. The assembly is simple and fast. The split design of the handle is realized, and at the same time, the fast installation structure of the handle is realized. The packaging volume required for the split structure is smaller, greatly reducing the packaging materials, effectively reducing the packaging cost, improving the market competitiveness of the product, and being convenient for transportation and effectively reducing the transportation cost. At the same time, it saves storage space, is energy-saving and environmentally friendly, and effectively reduces the costs of production, packaging, transportation and storage. Even if individual components of the fast installation structure of the handle are damaged, it is convenient for maintenance and replacement. The components can be recycled, without wasting materials and without scrapping the entire product due to the breakage of a certain component, effectively extending the service life of the handle structure and even the swivel chair.

[0020] The present invention realizes a fast installation structure of the handle of the base with a scientific and simple structure, a split design, fast installation, simple and fast assembly, a small required packaging volume, reduced packaging materials, reduced packaging costs and transportation and storage costs, convenient maintenance and replacement, and effectively extending the service life of the product.

[0021] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
