Description

Technical Field

[0001] This utility model relates to the field of horizontal bar technology, and in particular to a height-adjustable fixed base for a horizontal bar. Background Technology

[0002] In the fitness industry, the horizontal bar is a common piece of exercise equipment widely used in homes, schools, gyms, and communities. However, traditional horizontal bars are mostly of fixed height, making it difficult to accommodate the needs of people of different heights and limiting their applicability. At the same time, the support range of the fixed base is also fixed, which may lead to insufficient stability under different ground conditions or usage scenarios, potentially causing safety hazards. This is especially true in home fitness settings, where family members have significant height differences and the usage environment is complex, making it difficult for traditional horizontal bars to meet diverse usage needs. Therefore, designing a horizontal bar base that can flexibly adjust its height and provide stable support is key to solving these problems and improving the practicality and safety of the horizontal bar.

[0003] Based on the aforementioned usage context, the design of this adjustable-height fixed base for the horizontal bar must meet the following requirements: First, it must have a height adjustment function, enabling convenient, quick, and precise adjustment of the bar height to accommodate the exercise needs of users of different heights; second, it must have an expandable support structure, allowing for easy adjustment of the base's support range through simple operation, enhancing the stability of the horizontal bar under different ground conditions and usage scenarios; third, the overall structure must be sturdy and durable, ensuring that there will be no loosening or deformation during adjustment and use, thus guaranteeing user safety; fourth, the operation must be simple and easy to understand, requiring no professional tools or complex operating procedures, facilitating use and maintenance by various groups of people, thereby improving the versatility and accessibility of the horizontal bar.

[0004] To address this, we propose a height-adjustable fixed base for a single bar. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a height-adjustable fixed base for a single bar.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable height fixed base for a horizontal bar includes two bases. Two support rods are slidably connected to one end of each base. Two handles are fixedly installed on the upper surface of each support rod. Two support rods are slidably connected to the side of each base away from the support rods. The two support rods are arranged intersecting the two support rods. An extension component is installed inside each base. A reinforcing rod is fixedly installed on the side of each base that is close to each other. Two fixed rods are fixedly installed on the upper surface of each base. Two telescopic rods are slidably connected inside the fixed rods. An adjustment component is installed at the bottom end of each telescopic rod. A horizontal bar is fixedly installed on the side of the top ends of each telescopic rod that is close to each other.

[0008] As a further improvement of this utility model: the extension component includes a groove, and the two bases are provided with grooves, and two gears are rotatably connected inside the grooves.

[0009] As a further embodiment of this utility model: four racks are meshed on both sides of the two gears, and the four racks are fixedly connected to two support rods one and two support rods two respectively.

[0010] As a further embodiment of this utility model: the adjustment component includes a handle, two fixed rods are rotatably connected to the handle on opposite sides, and a worm gear is rotatably connected inside the two fixed rods, the worm gear being fixedly connected to the handle.

[0011] As a further improvement of this utility model: two worm wheels are meshed on one side of the worm gear, and the bottom ends of the two worm wheels are rotatably connected to two fixed rods respectively.

[0012] As a further embodiment of this utility model: two threaded rods are fixedly installed on the upper surfaces of the two worm gears, and the two threaded rods are respectively threadedly connected to two telescopic rods.

[0013] Compared with the prior art, this utility model provides a height-adjustable fixed base for a horizontal bar, which has the following beneficial effects:

[0014] This invention features a base with a groove and a gear and rack structure. Two gears mesh with four racks on each side, and the racks are fixedly connected to support rod one and support rod two. When adjusting the stability of the horizontal bar, simply apply external force to support rod one or support rod two, causing the racks to move. This rotates the gears, and the other meshing racks move accordingly, allowing support rod one and support rod two to expand or contract synchronously outward or inward. This structural design is not only easy to operate but also ensures consistent movement of the support rods on both sides through precise gear and rack transmission, effectively enhancing the stability of the horizontal bar in different usage scenarios. It avoids the risk of swaying due to unreasonable support range, improving user safety and experience.

[0015] This invention features a handle on the outside of a fixed rod that is fixedly connected to an internal worm gear. The worm gear meshes with a worm wheel, and a threaded rod mounted on the worm wheel is threadedly connected to a telescopic rod. By turning the handle, the user rotates the worm gear, which in turn rotates the threaded rod. Utilizing the principle of threaded transmission, the telescopic rod slides up and down within the fixed rod, allowing for precise adjustment of the horizontal bar's height. This adjustment method is effortless and highly accurate, allowing children, teenagers, and adults alike to quickly adjust the horizontal bar to a suitable height, meeting the exercise needs of people of different heights. This greatly expands the applicability of the horizontal bar, enabling it to function effectively in various settings such as home fitness, school physical education classes, and community fitness centers.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example: A height-adjustable fixed base for a horizontal bar, such as... Figures 1-4 As shown, the system includes two bases 1, with two support rods 2 slidably connected to one end of each base 1. Two handles 3 are fixedly installed on the upper surface of the two support rods 2. Two support rods 4 are slidably connected to the side of each base 1 away from the two support rods 2. The two support rods 4 are arranged intersecting with the two support rods 2. An extension component 5 is installed inside each base 1. A reinforcing rod 6 is fixedly installed on the side of each base 1 that is close to each other. Two fixing rods 7 are fixedly installed on the upper surface of each base 1. Two telescopic rods 8 are slidably connected inside the two fixing rods 7. An adjustment component 9 is installed at the bottom of each telescopic rod 8. A single bar 10 is fixedly installed on the side of each telescopic rod 8 that is close to each other.

[0025] like Figures 1-4 As shown, the expansion component 5 includes a groove 11. Two bases 1 have grooves 11. Two gears 12 are rotatably connected inside the grooves 11. Four racks 13 are meshed on both sides of the two gears 12. The four racks 13 are fixedly connected to two support rods 1 2 and two support rods 2 4 respectively. If the support range needs to be adjusted, support rods 1 2 or 2 4 are pushed. At this time, the racks 13 connected to the support rods move in the grooves 11, driving the gears 12 to rotate. The gears 12 then drive the other racks 13 to move, so that support rods 1 2 and 2 4 expand or contract synchronously. This, together with the reinforcing rod 6, enhances the overall stability of the base 1.

[0026] like Figures 1-3 As shown, the adjustment assembly 9 includes a handle 14, two fixed rods 7 rotatably connected to the handle 14 on opposite sides, a worm gear 15 rotatably connected inside the two fixed rods 7, the worm gear 15 being fixedly connected to the handle 14, two worm wheels 16 meshing with one side of the worm gear 15, the bottom ends of the two worm wheels 16 being rotatably connected to the two fixed rods 7 respectively, and two threaded rods 17 being fixedly installed on the upper surface of the two worm wheels 16 respectively, the two threaded rods 17 being threadedly connected to the two telescopic rods 8 respectively. When adjusting the height of the bar 10, rotating the handle 14 on the outside of the fixed rod 7 drives the worm gear 15 to rotate, the worm gear 15 meshes with the worm wheel 16, causing the worm wheel 16 to rotate, which in turn drives the threaded rod 17 to rotate. Since the threaded rod 17 is threadedly connected to the telescopic rod 8, as the threaded rod 17 rotates, the telescopic rod 8 slides up and down inside the fixed rod 7, thereby changing the height of the bar 10 to meet the needs of different users.

[0027] Working principle: When using the adjustable fixed base 1 of the horizontal bar 10, first place the two bases 1 in a suitable position. If the support range needs to be adjusted, push the support rod 1 2 or support rod 2 4. At this time, the rack 13 connected to the support rod moves in the groove 11, driving the gear 12 to rotate. The gear 12 then drives the other racks 13 to move, so that the support rod 1 2 and support rod 2 4 expand or contract synchronously. With the reinforcement rod 6, the overall stability of the base 1 is enhanced. When adjusting the height of the horizontal bar 10, rotate the handle 14 on the outside of the fixed rod 7, driving the worm gear 15 to rotate. The worm gear 15 meshes with the worm wheel 16, causing the worm wheel 16 to rotate, which in turn drives the threaded rod 17 to rotate. Since the threaded rod 17 is threadedly connected to the telescopic rod 8, as the threaded rod 17 rotates, the telescopic rod 8 slides up and down in the fixed rod 7, thereby changing the height of the horizontal bar 10 to meet the needs of different users. Throughout the process, the various components cooperate with each other to achieve flexible adjustment of the height and support range of the horizontal bar 10.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
