Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology and discloses a badminton net frame for sports teaching. Background Technology

[0002] A badminton net frame is a support structure used to hold a badminton net. It is positioned at the two midpoints of the badminton court's sidelines, responsible for extending the net to its standard height. Most sports venues use fixed frames, which typically have heavy bases and are difficult to move. Portable frames were developed to address the inconvenience of carrying or moving badminton net frames, or their unsuitability for use in ordinary residential areas, grassy areas, beaches, and courtyards. Many different types of portable badminton net frames have been designed and manufactured. Badminton net frames are essential equipment for badminton training and competition. When conducting badminton training outdoors, a portable net frame is necessary. However, existing net frame designs have certain flaws; disassembly and assembly are cumbersome, and the numerous parts make them inconvenient to carry and cause problems during use. Therefore, we have proposed a new type of badminton net frame for sports teaching.

[0003] To address the aforementioned problems, Chinese utility model patent (CN212214531U) discloses a badminton net frame for sports teaching, comprising a first support rod and a second support rod. A balance support plate is fixedly connected to the bottom of both the first and second support rods. A support frame is fixedly connected to the top of both the first and second support rods. A storage compartment is fixedly connected to the front end of the top of the first support rod. A net collector is fixedly connected to one side of the outer wall of the storage compartment. A take-up and release roll is rotatably connected to the center of the storage compartment. An elastic net is wound around the outer wall of the take-up and release roll. A drive motor corresponding to the take-up and release roll is installed at the center of the motor protective cover. Two sets of fixed hooks are fixedly connected to the end of the elastic net away from the take-up and release roll. This device solves the problem of traditional badminton net frames being immobile and inconvenient to transport, and also adds an automatic net collector, allowing for convenient and quick organization and storage of the net.

[0004] However, in actual badminton physical education teaching in primary and secondary schools, although the existing technical solutions can automatically set up and take down the net, a person still needs to hang the net on the corresponding hook on the support frame. It cannot be completely automated in terms of installation and takedown. Furthermore, the existing technical solutions are divided into two sets of net frames and one set of nets, making it difficult for one person to move three pieces of equipment simultaneously. In addition, during daily organization and use of the equipment, the previously organized setup often becomes messy and disorganized due to mistakes such as taking the wrong equipment or leaving it lying around. Utility Model Content

[0005] This invention provides a badminton net frame for physical education, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A badminton net frame for sports teaching includes a base, a net, and a telescopic mechanism. The base is connected to a sleeve, and a first support rod is slidably connected to the inner wall of the sleeve. The first support rod is connected to a storage box, which has a storage opening. A third support rod is connected to the inner wall of the storage box. The storage box is connected to a motor cover, and a motor is connected to the inner wall of the motor cover. The motor output shaft is connected to a driving bevel gear. The telescopic mechanism includes a second threaded rod, which has two sets. Each second threaded rod is connected to a driven bevel gear, which meshes with the driving bevel gear. The second threaded rod is threadedly connected to a first threaded rod. The storage box is connected to a first guide rod, which is threadedly connected to a second guide rod. The first threaded rod is threadedly connected to a slider, which is slidably connected to the second guide rod. The slider is connected to a second support rod. The net is connected to both the second and third support rods.

[0007] Preferably, the first support rod has a limiting through hole on its side wall, and the sleeve is threadedly connected to a limiting rod, which cooperates with the limiting through hole.

[0008] Preferably, the net is connected to hooks, and the hooks are provided in several groups, and the hooks are slidably connected to the second guide rod.

[0009] Preferably, the base is equipped with casters at its bottom.

[0010] Preferably, the outer wall of the sleeve is connected to a rib plate, and the rib plate is connected to the base.

[0011] Preferably, the outer wall of the storage box is connected with a buckle.

[0012] The beneficial effects of this technical solution compared to existing technologies are as follows: This technical solution changes the traditional badminton net frame's "two-pole, one-net" structure to a "one-pole, two-net" structure. Through a fully automated net deployment and retrieval system, it solves the problem of existing technologies, even with the addition of an automatic net-laying and retrieval device, still requiring manual net hanging. When the equipment is not in use, the threaded rod and guide rod in this technical solution can be removed and secured to the storage box with clips, while the net can be stored inside the box. Furthermore, the overall height of the device can be adjusted by changing the fit between the limiting rod and the limiting through-hole, thus accommodating students of different heights.

Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments: like Figures 1 to 4 The diagram shows a badminton net frame for sports teaching, comprising a base, a net, and a telescopic mechanism. A sleeve is connected to the top of the base, and a first support rod is slidably connected to the inner wall of the sleeve. A storage box is connected to the top of the first support rod, and a third support rod is connected to the inner wall of the storage box. A motor cover is connected to the top of the storage box, and a motor is connected to the inner wall of the motor cover. The motor output shaft is connected to a driving bevel gear. The telescopic mechanism includes a second threaded rod, which has two sets. The right second threaded rod is connected to a driven bevel gear, which meshes with the driving bevel gear. The right second threaded rod is screwed to the right first threaded rod. A first guide rod is connected to the side wall of the storage box. Figure 3 The enlarged view of the bevel gear shows that the first guide rod on the right is threadedly connected to the second guide rod on the right, the first threaded rod is threadedly connected to the slider, the slider is slidably connected to the second guide rod on the lower right, the slider on the right is connected to the second support rod, and the ball net on the right is connected to the second support rod on the right and the third support rod in the middle. The motion structure on the left is the same as above.

[0015] The side wall of the first support rod is provided with a limiting through hole, such as Figure 4 As shown in the enlarged view of the limiting rod, there are four sets of limiting through holes, and any one of the limiting through holes is slidably connected to the limiting rod.

[0016] The outer wall of the second guide rod is slidably connected to a hook, and multiple sets of hooks are provided. Any one of the hooks is connected to the net below.

[0017] The base has four sets of omnidirectional wheels attached to its bottom.

[0018] The outer wall of the sleeve is connected to four sets of ribs.

[0019] The storage box has eight sets of buckles on its outer side wall, which are symmetrically distributed. The storage box also has a side opening on its side wall.

[0020] After the motor is powered on and rotates, it drives the active bevel gear to rotate. The active bevel gear drives the driven bevel gear in the telescopic mechanism on the right to rotate. The rotation of the gears in turn drives the second threaded rod to rotate. The first threaded rod has a threaded groove connected to the second threaded rod. Because the second threaded rod rotates, it drives the first threaded rod to rotate. A slider is threadedly connected to the first threaded rod, and the other end of the slider slides on the second guide rod. Thus, the rotation of the first threaded rod can drive the slider to move to the right. The slider is connected to a vertically downward second support rod. Because a net is connected to the second support rod, the movement of the slider drives the movement of the second support rod. Because there is a hook on the second guide rod, the other end of the hook is connected to the net. Thus, the net can always move along the second guide rod when moving, thereby driving the movement of the net. The telescopic mechanism on the left works on the same principle. When the net needs to be retrieved, the slider on the right side of the telescopic mechanism moves to the left on the threaded rod on the right side, thereby driving the net through the retrieval port and back into the retrieval box. The retrieval mechanism on the left side works on the same principle. There are clips on the retrieval box. After the equipment is no longer in use, the threaded rod and guide rod can be removed and fixed to the retrieval box by the clips. Pulling out the limit rod allows the first support rod to slide up and down on the inner wall of the sleeve. Adjust it to the appropriate position, and reinsert the limit rod to fix the first support rod and the sleeve.

[0021] The specific implementation process is as follows: like Figures 1 to 4 The device, as shown, is a badminton net frame for physical education. During badminton classes, one student easily moves the device to the designated area using the wheels at the bottom. Once in position, the limit rod is removed according to the height of the group of students, and the net frame height is adjusted accordingly. After the limit rod is reinserted, the motor switch is turned on, and the sliders on the two sets of threaded rods move in opposite directions, dragging the guide rods connected to them. The net is connected to the third and second support rods, and the net is slowly pulled out of the storage box by the sliders. Students adjust the net length according to the actual size of the court, and then the motor is turned off, and badminton instruction can begin. The device can also be used by two groups. After training, the motor is turned on, the net is retracted into the storage box, the limit rod is removed to reset the net frame height, the sliders move in opposite directions, and the net is pulled through the storage opening and placed into the storage box. The threaded rods and guide rods are then removed and attached to the storage box with clips for subsequent use.

[0022] This technical solution improves upon existing solutions by changing the traditional badminton net frame's "two-pole, one-net" structure to a "one-pole, two-net" structure. Through a fully automated net deployment and retrieval system, it solves the problem of manual net hanging required even with an automatic deployment and retrieval device in existing solutions. When not in use, the threaded rod and guide rod can be detached and secured to a storage box with clips, while the net can be stored inside. The overall height of the device can be further adjusted according to the user's height by changing the relationship between the limiting rod and the limiting through-hole.

[0023] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
