Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a handlebar support rod for a fitness bicycle. Background Technology

[0002] An exercise bike is an indoor fitness equipment that simulates cycling. It mainly consists of a frame, flywheel, drive system, seat, and pedals. It works by using the user to pedal to drive the flywheel to rotate, generating resistance to achieve a workout effect. The resistance can be adjusted manually or automatically.

[0003] Most existing exercise bike handlebars can only be adjusted in height, not in the horizontal distance between the handlebar and the user. This makes it difficult to accommodate the body proportions of users with different body types. Differences in height and arm length may cause users to deliberately lean forward or backward to fit the handlebars. Long-term use can easily lead to shoulder and neck pain, and lower back strain, reducing exercise comfort and safety. This is especially unfriendly to special groups such as children and the elderly, limiting the universality of the equipment. The adjustment limit of some handlebars is mostly completed by a single pin. If the pin is not fully engaged, it may suddenly shift or fall off during riding, posing a safety risk. Utility Model Content

[0004] The purpose of this utility model is to provide a handrail support bar for exercise bikes, which can adjust the horizontal distance of the handrail to suit users of different body types, improve exercise comfort and safety, and effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A handlebar support for an exercise bike includes a base, a bracket fixedly connected to the base, a flywheel rotatably connected inside the bracket, a pedal mechanism fixedly connected inside the bracket near the flywheel, and the pedal mechanism and the flywheel being driven by a chain transmission mechanism. A seat is fixedly connected to the bracket, and a damping adjustment mechanism is movably connected to the bracket located above the flywheel. An L-shaped support rod is also fixedly connected to the bracket, and a sliding cover is movably connected inside the L-shaped support rod. Limiting plates are movably connected to both sides inside the sliding cover, and an operating handle is rotatably connected to the sliding cover near the limiting plates via a fixed shaft. A column is fixedly connected to the top of the sliding cover, and a handle is fixedly connected to the top of the column.

[0007] As a further preferred embodiment of this utility model, the top of the L-shaped support rod is provided with a sliding opening, and multiple first limiting grooves are provided on both sides of the L-shaped support rod. After the sliding opening is provided at the top of the L-shaped support rod, the sliding cover can be slidably connected to the L-shaped support rod and drive the column to move synchronously. The opening of the first limiting groove, together with the limiting insert plate, provides conditions for the sliding cover to drive multi-level adjustment and limiting.

[0008] As a further preferred embodiment of this utility model, a second limiting groove is provided on both sides of the sliding cover, and a fixing plate is fixedly connected to both sides of the sliding cover near the second limiting groove. The cooperation between the second limiting groove and the fixing plate can provide conditions for the limiting installation of the limiting plate inside the sliding cover.

[0009] As a further preferred embodiment of this utility model, the limiting insert plate is provided with a first mounting groove and a second mounting groove respectively. The limiting insert plate is inserted into the corresponding second limiting groove, and the fixing plate also passes through the first mounting groove. Multiple connecting bolts are threaded into the first mounting groove, and compression springs are fitted on the connecting bolts. One side of the compression spring abuts against one side of the first mounting groove, and the other side abuts against one side of the fixing plate. After the limiting insert plate is inserted into the second limiting groove, it is limited by the fixing plate to control the maximum reciprocating movement of the limiting insert plate. The compression spring provides power for the reset movement of the limiting insert plate.

[0010] As a further preferred embodiment of this utility model, one end of the operating handle is fixedly connected to two wedges. The wedges are also close to the side of the limiting plate via the operating handle. By rotating the operating handle around the fixed axis, the two wedges can be inserted into the second mounting slots of the corresponding limiting plates, thereby causing the two limiting plates to move relative to each other and causing one side of the two limiting plates to disengage from the corresponding first limiting slot, thus realizing the sliding adjustment of the sliding cover within the L-shaped support rod, thereby adjusting the usage position of the handle.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In this invention, the sliding cooperation between the L-shaped support rod and the sliding cover enables multi-level adjustment of the horizontal distance of the handrail, adapting to users of different heights and arm lengths. This avoids shoulder and neck pain and lumbar strain caused by deliberately leaning forward or backward, improving exercise comfort and safety. At the same time, the wedge block structure of the double-sided limiting plates, compression springs, and operating handle makes adjustment convenient and the limiting is stable and reliable, solving the problem of easy shaking in the existing single pin limiting mechanism.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-5 As shown, the present invention provides a handrail support for a fitness bicycle, including a base 1, a bracket 3 fixedly connected to the base 1, a flywheel 2 rotatably connected inside the bracket 3, a pedal mechanism 4 fixedly connected inside the bracket 3 near the flywheel 2, and the pedal mechanism 4 and the flywheel 2 are connected by a chain transmission mechanism. A seat cushion 5 is fixedly connected to the bracket 3. A damping adjustment mechanism 6 is movably connected to the bracket 3 above the flywheel 2. An L-shaped support rod 7 is fixedly connected to the bracket 3. A sliding cover 8 is movably connected inside the L-shaped support rod 7. Limiting plates 9 are movably connected to both sides inside the sliding cover 8. An operating handle 10 is rotatably connected to the sliding cover 8 near the limiting plates 9 via a fixed shaft 11. A column 12 is fixedly connected to the top of the sliding cover 8, and a handle 13 is fixedly connected to the top of the column 12.

[0021] like Figure 2 As shown, the top of the L-shaped support rod 7 has a sliding opening 14, and multiple first limiting grooves 15 are opened on both sides of the L-shaped support rod 7. After the sliding opening 14 is opened on the top of the L-shaped support rod 7, the sliding cover 8 can be slidably connected to the L-shaped support rod 7 and drive the column 12 to move synchronously. The opening of the first limiting grooves 15, together with the limiting insert plate 9, provides conditions for the sliding cover 8 to drive multi-level adjustment and limiting.

[0022] like Figures 1-5As shown, a second limiting groove 16 is provided on both sides of the sliding cover 8. A fixing plate 17 is fixedly connected to both sides of the sliding cover 8 near the second limiting groove 16. The cooperation between the second limiting groove 16 and the fixing plate 17 provides conditions for the limiting insert 9 to be installed in the sliding cover 8. A first mounting groove 18 and a second mounting groove 19 are respectively provided in the limiting insert 9. The limiting insert 9 is inserted into the corresponding second limiting groove 16, and the fixing plate 17 also passes through the first mounting groove 18. Multiple connecting bolts 20 are threaded in the first mounting groove 18. A compression spring 21 is fitted on the connecting bolt 20. One side of the compression spring 21 abuts against one side of the first mounting groove 18, and the other side abuts against one side of the fixing plate 17. After being inserted into the second limiting groove 16, the limiting plate 9 is limited by the fixing plate 17, which controls the maximum reciprocating movement of the limiting plate 9. The compression spring 21 provides power for the reset movement of the limiting plate 9. One end of the operating handle 10 is fixedly connected to two wedges 22. The wedges 22 are also close to the limiting plate 9 via the operating handle 10. By operating the operating handle 10 to rotate around the fixing shaft 11, the two wedges 22 can be inserted into the second mounting groove 19 of the corresponding limiting plate 9, thereby causing the two limiting plates 9 to move relative to each other and causing one side of the two limiting plates 9 to disengage from the corresponding first limiting groove 15, so as to realize the sliding adjustment of the sliding cover 8 in the L-shaped support rod 7, thereby adjusting the use position of the handle 13.

[0023] It should be noted that this utility model is a handlebar support rod for a fitness bicycle. When the position of the handlebar 13 needs to be adjusted, the user operates the operating handle 10, rotating it around the fixed shaft 11. This causes the two wedges 22 at one end of the operating handle 10 to rotate synchronously. The wedges 22 gradually insert into the second mounting groove 19 of the corresponding limiting plate 9. The thrust of the wedge structure causes the two limiting plates 9 to move relative to each other along the second limiting groove 16, compressing the compression spring 21 on the connecting bolt 20, until the limiting plate 9 moves from the first limiting position inside the L-shaped support rod 7. When the slide cover 8 is completely disengaged from the groove 15, it is unlocked. The user can then push the column 12 to make the slide cover 8 slide along the sliding opening 14 at the top of the L-shaped support rod 7 within the L-shaped support rod 7, causing the handle 13 to move synchronously to adjust the horizontal distance, thereby meeting the needs of users of different body types. After adjusting to the appropriate position, the operating handle 10 is released, the compression spring 21 releases its elastic potential energy, and pushes the limiting plate 9 to move in the opposite direction. The fixing plate 17 restricts the movement of the limiting plate 9, ensuring that the limiting plate 9 is accurately inserted into the corresponding first limiting groove 15, thus completing the locking.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
