The two lower assembly rods 31 are arranged at intervals and penetrate the two lower assembly holes 14 of the body 10. The free ends of the two lower assembly rods 31 are respectively provided with a screw connection portion 311, and the screw connection portion 311 has an external thread. In this embodiment, the external thread of the screw connection portion 311 of the two lower assembly rods 31 and the external thread of the screw connection portion 211 of the upper assembly rod 21 have the same pitch, so the same four fixing components 40 can be used to connect them, and the upper assembly member 20 and the lower assembly member 30 can be adjusted; in this embodiment, there is an angle θ between the lower sleeve portion 32 and the two lower assembly rods 31, such as Figure 3 As shown, when the lower assembly member 30 is assembled on the body 10, the lower sleeve portion 32 is close to the upper sleeve portion 22. After the upper assembly member 20 and the lower assembly member 30 are assembled on the body 10, a clamping space is formed between the upper assembly member 20 and the lower assembly member 30 and the connecting groove 12 for assembly with the bicycle, and a clamping position is formed between the upper sleeve portion 22 and the lower sleeve portion 32.

[0035] Each of the aforementioned fixing components 40 is formed by a washer 41, an elastic member 42, a screw member 43 and an external screw member 44. The elastic member 42 is preferably an elastic washer, the screw member 43 is preferably a nut, and the external screw member 44 is preferably a so-called round cover nut. The fixing components 40 can connect the screw connection parts 211 of the two upper connecting rods 21 and the screw connection parts 311 of the two lower connecting rods 31. When the two upper connecting rods 21 are inserted into the two upper connecting holes 13 of the body 10 or the two lower connecting rods 31 are inserted into the two lower connecting holes 14, the washer 41 is sleeved on the upper connecting rods 21 and the lower connecting rods 31, and then the elastic member 42 is sleeved on the upper connecting rods 21 and the lower connecting rods 31. The upper assembly member 20 and the lower assembly member 30 are combined and fixed to the body 10, and then the outer screw members 44 are screwed onto the ends of the screw portions 211 and 311 to cover the ends of the screw portions 211 and 311 and prevent the screw portions 211 and 311 from being exposed.

[0036] Two sheet-shaped abutting members 50 , preferably made of metal, are respectively disposed on the top and bottom surfaces of the main body 10 . The two abutting members 50 are respectively provided with two through holes 51 corresponding to the two through holes 15 of the main body 10 .

[0037] A support frame 60 has two frame rods 61 and a support portion 63. The two frame rods 61 are upright and spaced apart. The two frame rods 61 are provided with a shoulder 611 on their shafts. The outer diameter of the two shoulders 611 is larger than the diameter of the through hole 15 of the body 10 and the diameter of the through hole 51 of the two abutting members 50. In this embodiment, the lower half of the frame rod 61 is made into a small diameter section to form the shoulder 611. The two frame rods 61 are passed through the two through holes 15 of the body 10 and the through holes 51 of the two abutting members 50 from top to bottom, and the two shoulders 611 abut against the abutting members 50 on the top surface of the body 10. The bottom ends of the two rack rods 61 are respectively provided with a screw hole 612, and two screw connection elements 64 are respectively screwed to the screw holes 612 at the bottom ends of the two rack rods 61 from the bottom side of the body. Preferably, the two screw connection elements 64 are screw rods, and their heads 641 are clamped against the abutment 50 on the bottom surface of the body 10. Figure 1 One end of the support portion 63 is connected to the top of the two frame rods 61 through an extension portion 62, and extends obliquely upward from the two frame rods 61. The extension portion 62 is a bending portion between the two frame rods 61 and the support portion 63. The width of the support portion 63 is smaller than the width between the two frame rods 61. The width of the extension portion 62 gradually decreases from the two frame rods 61 to the support portion 63. In this embodiment, the two support portions 63 are elongated hollow frames, which are convenient for combining with the bottom surface of the baby seat, but not limited to this. The extension portion 62 is formed by two rod portions.

[0038] A protective cover 70 has two buckle plates 71 formed on both sides. The two buckle plates 71 are buckled on the arc portion 16 of the main body 10 to form a buckled fixation. The protective cover 70 is set in front of the main body 10, and its body is provided with four through holes 72 at positions corresponding to the two upper assembly holes 13 and the two lower assembly holes 14.

[0039] The assembly structure of the utility model can be assembled on the frame of a bicycle or removed from the frame. Figure 5As shown, when the assembly structure of the present invention is to be assembled on a bicycle frame F, the front end of the bicycle frame F has an upper tube F1, a lower tube F2 and a head tube F3. First, the assembly surface 11 of the rear end of the body 10 faces the front end of the head tube F3 so that the connection groove 12 can be combined with the head tube F3. The upper assembly hole 13 and the lower assembly hole 14 of the body 10 are respectively located on two sides of the head tube F3. Then, the upper assembly rod 21 of the upper assembly member 20 is inserted between the upper tube F1 and the lower tube F2. The two upper assembly holes 13 of the main body 10 are inserted from the back to the front, and the two upper assembly rods 21 are located on both sides of the head tube F3, so that the upper sleeve portion 22 of the upper assembly member 20 is located between the upper tube F1 and the lower tube F2, and can cover the periphery of the head tube F3; and the lower assembly member 30 is passed through the head tube F3 from the bottom of the lower tube F2, and the two lower assembly rods 31 are inserted into the lower assembly holes 14 of the main body 10 from both sides of the head tube F3, and the lower sleeve portion 32 can cover the periphery of the head tube F3. Next, the screw connection member 43 of the fixing assembly 40 is screwed to tighten the two upper assembly rods 21 and the two lower assembly rods 31, so that the upper sleeve portion 22 of the upper assembly member 20 and the lower sleeve portion 32 of the lower assembly member 30 are close to the head tube F3, and the clamping space can be gradually reduced, so that the connection groove 12 of the main body 10 and the upper sleeve portion 22 of the upper assembly member 20 and the lower sleeve portion 32 of the lower assembly member 30 can gradually fit the front and rear peripheries of the head tube F3, so that the main body 10 and the upper assembly member 20 and the lower assembly member 30 are tightly fixed between the head tube F3, the upper tube F1 and the lower tube F2, and because the lower sleeve portion 32 has an angle, the clamping position between the upper sleeve portion 22 and the lower sleeve portion 32 gradually clamps and tightens the lower tube F2, so that the main body 10 can be stably set on the head tube F3 at the front end of the frame F.

[0040] Next, the two rods 61 of the support frame 60 are inserted into the through holes 15 of the body 10, and the support portion 63 is directed toward the rear side of the frame F, and the two screwing elements 64 are screwed into the screw holes 612 at the bottom ends of the two rods 61, so that the shoulders 611 of the two rods 61 and the heads 641 of the two screwing elements 64 are respectively pressed against the abutment 50 on the top and bottom surfaces of the body 10. After assembly, the infant seat clamping structure of the utility model is located at the center of the frame F, and the support portion 63 is disposed above the upper tube F1.

[0041] See also Figure 6 As shown, the joint S1 at the bottom of a baby seat S is mounted on the support portion 63 of the support frame 60, so that the baby seat S is detachably fixed to the support frame 60, and the assembly is completed. The connection structure between the baby seat S and the support frame is not the main subject of the present invention and will not be described in detail.

[0042] When the clamping structure is to be disassembled, the baby seat S is first removed from the support frame 60, and then the support frame 60, the lower assembly member 30 and the upper assembly member 20 are sequentially disassembled, and the body 10 can be separated from the frame F. The user can assemble or disassemble it according to the needs, and can use it on different bicycles and can also match different baby seats S.

[0043] The front-mounted baby seat clamping structure of the present invention adds a mounting bracket to the bicycle frame to facilitate the installation of the baby seat. The clamping structure can be fixed to the periphery of the head tube of the bicycle through the combination of the main body, the upper assembly member and the lower assembly member, and can be freely disassembled and installed. Compared with the baby seat on the known bicycle that is set on the upper tube or the seat tube of the frame and is not easy to ride, the present invention is designed to be detachable and assembleable at the position of the head tube, so that the baby seat can be set above the front end of the bicycle. In addition to making it easy to observe the condition of the infant, the interference with riding can also be greatly reduced.

[0044] The above embodiments are only for explaining the technical means of the utility model and are not for limiting. Any equivalent modifications of the utility model shall be deemed as the protection scope of the utility model. The front-mounted infant seat clamping structure of the utility model is the first structure in this field and has improved practical effects, so the application is filed in accordance with the law.
