Abstract
Description
Technical Field
[0001] This utility model relates to the field of badminton net frame technology, specifically a badminton net frame. Background Technology
[0002] A badminton net frame typically consists of two bases with uprights fixed on them. The net is stretched between the two uprights. To facilitate moving the bases to different locations, rollers are sometimes installed on the outside of the bases. Generally, the two bases, each with two uprights, are positioned at the two midpoints of the badminton court sideline. They are responsible for stretching the badminton net to the standard height and serving as the boundary of the playing area.
[0003] Most of the rollers remain exposed on the outside of the base when not in use. Long-term exposure to the natural environment can easily cause the rollers to rust. Rusty rollers make it difficult to move the base. In addition, most badminton nets have a fixed length when stretched. In informal competitions, such as family gatherings or recreational activities among friends, multiple people will be arranged to play on both sides of the net. In this case, a fixed-length net is not conducive to extending the playing area. Or, when the court is small, a fixed-length net is not easy to shorten by adjusting the pole to adapt to the court. Utility Model Content
[0004] The purpose of this invention is to provide a badminton net frame to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A badminton net frame, comprising:
[0007] The base consists of two bases, each base including a support box. Mounting boxes are fixed on both sides of the support box. A connecting seat is inserted into the bottom of the mounting box. A roller is rotatably connected to the outside of the connecting seat. A sleeve is fixed to one end of the support box.
[0008] Two uprights are inserted and fixed into the corresponding sleeves, and an arc-shaped receiving groove is provided on the outer side of the uprights;
[0009] There are two shafts, which are movably engaged in the arc-shaped receiving grooves at corresponding positions, and a ball net is wound and fixed between the two shafts.
[0010] Furthermore, the support box contains sandbags, and the open end of the support box is detachably fixed with a cover plate.
[0011] Furthermore, a diagonal brace is fixed between the sleeve and the support box, and a handle is fixed to the top surface of the mounting box.
[0012] Furthermore, a hexagonal protrusion is fixed to the inner bottom surface of the sleeve, and a positioning hole is provided on the bottom surface of the upright.
[0013] Furthermore, the inner top and inner bottom of the arc-shaped receiving groove are both fixed with pins, and both ends of the shaft are provided with rectangular holes for movable insertion with the pins.
[0014] Furthermore, one end of one of the support boxes is fixed with an arc-shaped locking block, and one end of the other support box is provided with an arc-shaped locking groove, wherein the arc-shaped locking block and the arc-shaped locking groove are slidably engaged.
[0015] Furthermore, the central angle corresponding to the arc-shaped slot is greater than 180 degrees.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. By movably inserting the connector with rollers into the mounting box, rollers are installed on both sides of the base, making it easy to move the base on the ground. When the base is moved to the predetermined position and the rollers are no longer needed, the connector with rollers can be removed from the mounting box and stored inside the support box. This can, to some extent, prevent the rollers from being exposed on the outside of the base for a long time when not in use, thus preventing corrosion.
[0018] 2. By winding and fixing multiple rolls of net onto each axle, the net can be released or rolled up by rotating the axle. This allows the net between two axles to be pre-adjusted to a suitable length. The axle is then snapped into the arc-shaped receiving groove of the upright, and the pin inside the arc-shaped receiving groove is inserted and fixed into the rectangular hole of the axle, restricting further rotation of the axle to release or roll up the net. The axle is then inserted into the sleeve to support and tension the net to a suitable length. When multiple people are playing on both sides of the net, the net between the two axles can be pre-released to lengthen it. When the net installation area is narrow, the net between the two axles can be pre-rolled to shorten it, making the net suitable for different playing situations. Attached Figure Description

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1, please refer to Figure 1 - Figure 5 In this embodiment of the utility model, a badminton net frame includes two bases 100. Each base 100 includes a support box 110. Mounting boxes 120 are fixed on both sides of the support box 110. A connecting seat 130 is inserted into the bottom of the mounting box 120. A roller 131 is rotatably connected to the outer side of the connecting seat 130. A sleeve 140 is fixed to one end of the support box 110. A vertical rod 200 is movably inserted into the sleeve 140. An arc-shaped receiving groove 210 is opened on the outer side of the vertical rod 200. A shaft 300 is movably engaged inside the arc-shaped receiving groove 210. A net 310 is wound and fixed between the two shafts 300.
[0027] Specifically, by designing the base as a support box 110, it is convenient to place heavy objects, such as sandbags, inside the support box 110 to increase the weight of the support base 100. When the base 100 is not in use, the counterweights can be removed to reduce its weight and make it easier to carry. When the base 100 needs to be moved, the connecting seat 130 with rollers 131 is pre-installed into the mounting box 120, so that both sides of the base 100 are equipped with rotatable rollers 131, thereby facilitating the movement of the base 100. When the base 100 does not need to be moved... The connecting seat 130, along with the roller 131, can be removed from the base 100 and stored inside the support box 110 to prevent the roller 131 from rusting and being damaged due to long-term exposure to the outdoors. Before installing the net 310, the axle 300 can be rotated to wind up or release the net 310, thereby pre-adjusting the net 310 between the two axles 300 to a preset length. Then, the axle 300 is installed onto the base 100 via the upright 200, which makes it easier for the length of the net 310 to be suitable for playing in different situations.
[0028] like Figure 1 As shown, in this embodiment, the open end of the support box 110 is detachably fixed with a cover plate 111. Opening the cover plate 111 allows the disassembled connecting seat 130 and roller 131 to be stored inside the support box 110, preventing the roller 131 from being exposed to the outdoors for a long time and causing rust and damage, which helps to extend the service life of the roller 131.
[0029] In this embodiment, sandbags are placed inside the support box 110. The sandbags are mainly used as counterweights to improve the stability of the support box 110 fixed to the ground. Of course, other counterweights can also be used. For example, outdoors, bags filled with soil can be placed inside the support box 110. The specific type of counterweight can be flexibly selected according to the usage requirements.
[0030] like Figure 1 and Figure 2 As shown, in this embodiment, a diagonal brace 141 is fixed between the sleeve 140 and the support box 110. The diagonal brace 141 securely mounts the sleeve 140 to the top of the support box 110. A handle is fixed to the top surface of the mounting box 120. During the installation of the roller 131, one end of the support box 110 can be lifted by the handle, and then the connecting seat 130 can be inserted into the mounting box 120, thereby installing the connecting seat 130 with the roller 131 onto the outside of the mounting box 120.
[0031] like Figure 3 As shown, in this embodiment, a hexagonal protrusion is fixed on the inner bottom surface of the sleeve 140, and a positioning hole 230 is provided on the bottom surface of the upright 200. The upright 200 is inserted into the sleeve 140, so that the positioning hole 230 with a hexagonal cross section at the bottom of the upright 200 fits onto the hexagonal protrusion, preventing the upright 200 from rotating inside the sleeve 140.
[0032] like Figure 3 and Figure 4 As shown, in this embodiment, the inner top and inner bottom of the arc-shaped receiving groove 210 are both fixed with pins 220. Both ends of the shaft 300 are provided with rectangular holes 320 that are movably inserted into the pins 220. After the length of the net 310 between the two shafts 300 is adjusted, the positioning holes 230 at both ends of the shaft 300 are respectively inserted into the corresponding pins 220. The pins 220 restrict the shaft 300 from rotating inside the upright 200, so that the two shafts 300 will not automatically rotate to adjust the length of the net 310.
[0033] In this embodiment, a rubber sleeve is fixed to the outer side of the pin 220. The rubber sleeve increases the friction between the pin 220 and the rectangular hole 320, so that the pin 220 can be firmly inserted and fixed inside the rectangular hole 320.
[0034] In Example 2, based on Example 1, in order to combine the support boxes 110 on the two bases 100 together, so that the two bases 100 can be moved at the same time.
[0035] like Figure 1 and Figure 5 As shown, in this embodiment, one end of a support box 110 is fixed with an arc-shaped locking block 150, and one end of another support box 110 is provided with an arc-shaped locking groove 160, and the arc-shaped locking block 150 and the arc-shaped locking groove 160 are slidably engaged.
[0036] Specifically, when it is necessary to move the two bases 100 at the same time, the two bases 100 can be brought close to each other and staggered. The base 100 with the arc-shaped locking block 150 fixed can then slide towards the other base 100, so that the arc-shaped locking block 150 can slide into the arc-shaped locking groove 160, thereby connecting and fixing the two support boxes 110 together. A vertical rod 200 can be inserted into the sleeve 140 of the base 100 to facilitate pushing the two bases 100.
[0037] In this embodiment, the central angle corresponding to the arc-shaped slot 160 is greater than 180 degrees, so that after the arc-shaped card block 150 is slidably inserted into the arc-shaped slot 160, the arc-shaped card block 150 will not separate from the arc-shaped slot 160.
[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
