[0020] 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.

[0021] Reference Figures 1 to 4 , an embodiment of a sliding door handle structure of the present invention is proposed, which is installed on both sides of the door body of the sliding door, and the sliding door handle structures on both sides are connected by a square core.

[0022] The sliding door handle structure includes an inner ring that can be embedded and fixed on the side of the door body, a base plate 200 installed at the inner bottom of the inner ring, a knob 300 that passes through the base plate 200 and is fixed to the bottom of the inner ring, and an outer cover 400 that is adapted to the inner ring and covers the outside of the inner ring.

[0023] A mounting post 301 extends inward from the knob 300 . A first annular slot 302 is provided on the side wall of the mounting post 301 . A square core hole 303 is provided inside the mounting post 301 for a square core card to be inserted and connected and fixed.

[0024] The bottom plate 200 is provided with a bottom plate hole 202 through which the mounting post 301 of the knob 300 can pass.

[0025] The inner ring includes a hollow cylindrical shell portion 101 and an outer edge portion 102 extending outward from the opening of the cylindrical shell portion 101. The bottom of the inner ring is provided with a knob mounting hole adapted to and snap-fit ​​with the first annular clamping groove 302. The knob mounting hole is provided with a plurality of first notch grooves 103 toward the outside to increase the tension and elasticity of the knob mounting hole, so that the first annular clamping groove 302 and the knob mounting hole can be snap-fitted and fixed easily and quickly. A plurality of separate first clamping blocks 104 are formed between adjacent first notch grooves 103, and the first clamping blocks 104 are snap-fitted and fixed with the first annular clamping groove 302. Among them, the first notch groove 103 can increase the tension and elasticity of the knob mounting hole, so that the first annular clamping groove 302 and the knob mounting hole can be snap-fitted and fixed easily and quickly. Such a structural design is simple and novel, forming a snap-fit ​​assembly structure with tension, while saving materials and effectively reducing production costs. Such a simple structural change can bring such a huge effect without adding any additional cost and can even effectively reduce production costs. It can solve the common problem of difficult snap-on operations, greatly improve assembly efficiency, and has strong practicality and creativity.

[0026] The inner end of the first clamping block 104 is configured as an inclined surface to facilitate the first annular clamping groove 302 to be clamped and fixed to the first clamping block 104 .

[0027] The inner side wall of the cylindrical shell part 101 of the inner ring is provided with a plurality of second clamping blocks 105, and the outer side wall of the outer cover 400 is provided with a second annular clamping groove 401 correspondingly adapted to the second clamping blocks 105 and for the second clamping blocks 105 to be clamped into so that the outer cover 400 is clamped and fixed on the inner ring.

[0028] The outer edge portion 102 of the inner ring is provided with a stopper 106 facing outward, and the outer cover 400 is provided with a stopper slot 402 that is adapted to and can be engaged with the stopper block 106. When installing the outer cover 400, it is only necessary to align the stopper slot 402 of the outer cover 400 with the stopper block 106 of the inner ring, and then snap the outer cover 400 into the inner ring so that the second block 105 is engaged and fixed with the second annular slot 401. The assembly is simple and convenient, and the assembly efficiency is high.

[0029] A plurality of second notches 107 are provided at the bottom edge of the cylindrical shell portion 101 and the inner edge of the outer edge portion 102. Such a structural design is simple and novel, and forms a snap-on assembly structure with tension. The second notches 107 at the bottom edge of the cylindrical shell portion 101 can increase the tension of the knob mounting hole, so that when the mounting post 301 of the knob 300 is inserted into the knob mounting hole, the mounting post 301 will have an outward squeezing effect on the knob mounting hole. In the present application, the first notches 103 and the second notches 107 at the bottom edge of the cylindrical shell portion 101 are provided, so that the knob mounting hole has a certain tension, and can be slightly deformed with the squeezing effect of the mounting post 301. When the first clamping block 104 is clamped and fixed with the first annular clamping groove 302, the knob mounting hole will return to its original state, so that the installation and disassembly is very simple and convenient, and the installation efficiency is high. The bottom edge of the cylindrical shell part 101 and the inner edge of the outer edge part 102 can increase the tension of the side wall of the cylindrical shell part 101. In this way, when the outer cover 400 is engaged with the inner ring, the outer cover 400 will have an outward extrusion effect on the side wall of the cylindrical shell part 101. The setting of the second notch groove 107 makes the side wall of the cylindrical shell part 101 have a certain tension, which can be slightly deformed with the extrusion of the outer cover 400. After the second clamping block 105 is engaged and fixed with the second annular clamping groove 401, the side wall of the cylindrical shell part 101 will return to its original state, so that the installation and disassembly is very simple and convenient, and the installation efficiency is high. At the same time, the second notch groove 107 can save materials and effectively reduce production costs. Moreover, such a simple structural change can bring such a huge effect without any additional cost, and can even effectively reduce production costs. It can solve the common problem of difficult buckle operation, greatly improve assembly efficiency, and have strong practicality and creativity.

[0030] The outer edge 102 of the inner ring is provided with a plurality of screw holes 108 for fixing the inner ring to the side of the door body by screw connection. The outer cover 400 covers the screws on the inner ring, and the screws are not visible from the outside, making the surface of the sliding door buckle structure simple and elegant with high aesthetics.

[0031] The bottom of the inner ring is provided with a bottom annular groove 109 which is adapted to the bottom plate 200 and can be inserted into the bottom plate 200. The bottom annular groove 109 is provided with a plurality of limiting protrusions 110 facing inward. The bottom plate 200 is provided with limiting notches 201 corresponding to the limiting protrusions 110, so as to facilitate the rapid positioning and fixing of the bottom plate 200.

[0032] The thickness of the first clamping block 104 is smaller than the overall thickness of the inner bottom of the inner ring, thereby effectively increasing the tension of the knob mounting hole, thereby making it easier and faster to buckle and fix the first annular clamping groove 302 to the knob mounting hole.

[0033] The thickness of the side wall of the inner cylindrical shell portion 101 corresponding to the second clamping block 105 is relatively thin, which can effectively increase the tension at the second clamping block 105. If the side wall of the entire cylindrical shell portion 101 is of uniform thickness, the second clamping block 105 is not easy to open even if squeezed, which will affect the convenience of the buckle operation and is not durable enough.

[0034] The inner ring is an integrally formed structure and can be made of different materials. In this embodiment, the inner ring is made of plastic.

[0035] In addition, the existing sliding door handle structure generally only has a groove at the handle position, and the user extends a finger to hold the groove to drive the door body to move. This driving method makes the sliding door operation more laborious, and the finger is easy to slip out of the groove, which is generally not practical. However, the sliding door handle structure adopts a knob method. When the door needs to be moved, the user extends a finger to grab the knob 300 to operate the door body. At this time, the knob 300 plays the role of a door handle, making the sliding door easy and easy to operate, not easy to slip out, and highly practical.

[0036] During installation, first embed the base plate 200 into the inner bottom of the inner ring, and then buckle the knob 300 so that the first annular groove 302 on the mounting column 301 of the knob 300 is buckled and fixed with the first groove, and then use screws, screw holes 108 on the outer edge portion 102 of the inner ring, and screw holes 108 on the door body to screw the inner ring to the side of the door body, and finally align the limiting groove 402 of the outer cover 400 with the limiting block 106 of the inner ring. After alignment, buckle the outer cover 400 into the inner ring so that the second block 105 is buckled and fixed with the second annular groove 401. The assembly is simple and convenient, and the installation efficiency is high.

[0037] The present invention realizes a simple and novel structural design, a snap-on assembly structure with tension, which makes installation and disassembly simple and quick, with high installation efficiency, and there are no screws on the product surface, making the appearance simple and elegant with high aesthetics. The sliding door is easy and simple to operate, not easy to slide out, and has a sliding door buckle structure with strong practicality.
