Description

Technical Field

[0001] This utility model relates to the field of bicycle frames, and more particularly to a quick-release modular magnesium alloy frame. Background Technology

[0002] The bicycle frame is the core component of a bicycle. It supports and connects various parts, provides mounting positions for wheels, handlebars, and seats, maintains the stability of the bicycle frame and the overall structural integrity, and effectively transmits the rider's power to the drive system, enabling the bicycle to travel smoothly and efficiently.

[0003] Traditional bicycle frames have some shortcomings: on the one hand, the installation of traditional support bars is cumbersome and not secure, requiring multiple adjustments with tools, resulting in low installation efficiency; on the other hand, some traditional frames lack a quick-installation cup holder design, making it difficult to meet the rider's need for convenient drinking water during the journey, thus limiting their practicality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-release modular magnesium alloy frame. This frame utilizes a wedge-shaped block and a sliding groove in the first mounting ring for rapid positioning, combined with a rotating buckle design in the second mounting ring, significantly improving installation efficiency and stability. Simultaneously, a cup holder mounting block is integrated at the bottom of the first support rod, giving the frame a convenient drinking function. This effectively solves the problems of cumbersome installation and limited functionality of traditional bicycle frames, balancing efficient assembly with ease of riding.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A quick-release modular magnesium alloy frame includes: a main support rod and a first mounting sleeve. A second mounting sleeve is fixedly connected to the outer wall of the main support rod. A first mounting ring is slidably connected to the outer wall of the second mounting sleeve. A connecting rod is fixedly connected to the outer wall of the inner ring of the first mounting ring. A quick-fixing component is installed at the bottom of the connecting rod. A first support rod is installed inside the second mounting sleeve. A groove is formed at the bottom of the first support rod. A cup holder fixing component is installed inside the groove. A slot is formed on one side of the first support rod.

[0007] Furthermore, the quick-fixing assembly includes a wedge block slidably connected to the outer wall of the connecting rod, the outer wall of the connecting rod is provided with a first spring, and the outer wall of the second mounting sleeve is provided with four first sliding grooves at equal intervals, the wedge block being slidably connected inside the first sliding grooves.

[0008] Further, a second mounting ring is installed on one side of the outer wall of the second mounting sleeve. A second spring is provided between the second mounting ring and the first mounting ring. The second spring is disposed on the outer wall of the second mounting sleeve. One side outer wall of the first mounting ring is fixedly connected to a first mounting block, and the outer wall of the second mounting ring is fixedly connected to a second mounting block. A circular hole is formed in the first mounting block, and a threaded rod coaxial with the hole is provided on the second mounting block.

[0009] Further, the cup holder fixing assembly includes a cup holder mounting block slidably connected inside the groove. Two second sliding grooves are formed in the inner wall of the first support rod. A fixing block is slidably connected inside the second sliding groove. One side of the second sliding groove is in a "冂" shape.

[0010] Further, one side of the main support rod is fixedly connected to the inner wall of the first mounting sleeve. An installation rod is threadedly connected inside the first mounting sleeve. Two second support rods are installed on one side of the installation rod.

[0011] Further, one side of the first support rod is threadedly connected to the inner wall of the first mounting sleeve. A screw rod is threadedly connected inside the first mounting sleeve. The screw rod passes through the inside of the first support rod.

[0012] Further, one side of the first mounting sleeve is fixedly connected to an installation pipe.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, the rapid installation and fixation of the support rod are realized. When pulling the first mounting ring, the wedge-shaped block on its inner ring slides along the first sliding groove and accurately fits into the clamping groove of the first support rod to complete the preliminary installation. Subsequently, rotating the second mounting ring makes the second mounting block on its outer wall snap into the first mounting block, further realizing firm fixation, reducing the installation time, and improving the installation efficiency.

[0015] 2. In the utility model, by providing a groove at the bottom of the first support rod and internally installing a cup holder mounting block, it is convenient to install the cup holder at its bottom. This design meets the drinking water needs of cyclists, improves the usage experience, and further enhances the convenience during cycling. BRIEF DESCRIPTION OF THE DRAWINGS

An mounting tube 3 is fixedly connected to one side of the first mounting sleeve 4.

[0024] Specifically, the first support rod 2 is installed in the first mounting sleeve 4 at the top of the mounting pipe 3, and then the screw rod 22 is inserted into the preset threaded hole to further fix the first support rod 2. Then, the first support rod 2 is inserted into the second mounting sleeve 7, and the first mounting ring 20 is pushed towards the main support rod 1, so that the wedge block 14 inside it is clamped into the internal card slot 15 to fix the first support rod 2. Subsequently, the mounting rod 6 is fixed inside the first mounting sleeve 4 installed on the rear side of the main support rod 1, and then the second support rod 5 is installed on the rear side of the mounting rod 6, thus completing the installation of the entire vehicle.

[0025] Refer to Figure 1 and Figure 2 , the outer wall of the connecting rod 8 is slidably connected to the wedge block 14. A first spring 9 is arranged on the outer wall of the connecting rod 8. Four first sliding grooves 10 are equidistantly opened on the outer wall of the second mounting sleeve 7. The wedge block 14 is slidably connected inside the first sliding groove 10. A second mounting ring 21 is installed on one side of the outer wall of the second mounting sleeve 7.

Two second sliding grooves 17 are opened on the inner wall of the first support rod 2. A fixing block 18 is slidably connected inside the second sliding groove 17. One side of the second sliding groove 17 is in a "冂" shape.

[0028] Specifically, by sliding the cup holder mounting block 19 into the groove 16 and then clamping the fixing block 18 sliding inside the second sliding groove 17 into the "冂" shaped groove, the fixing of the cup holder mounting block 19 is realized, improving the efficiency of installing the cup holder.

[0029] Working principle: First, the first support rod 2 is installed in the first mounting sleeve 4 at the top of the mounting tube 3, and further fixed by screwing the screw 22 into the threaded hole. Next, the first support rod 2 is inserted into the second mounting sleeve 7, and the first mounting ring 20 is pushed towards the main support rod 1, so that the wedge block 14 is engaged in the slot 15 of the first support rod 2 under the elastic force of the first spring 9, achieving quick fixation. Subsequently, the mounting rod 6 is fixed in the first mounting sleeve 4 on the rear side of the main support rod 1, and then the second support rod 5 is installed on the rear side of the mounting rod 6, completing the frame body installation. For the cup holder installation, the cup holder mounting block 19 is slid into the bottom groove 16 of the first support rod 2, and is engaged in the "U"-shaped groove of the second sliding groove 17 by sliding the fixing block 18, completing the cup holder fixation. The entire frame and cup holder installation process achieves efficient and convenient assembly through modular design and quick-fixing components.
