Also, the technical means between each embodiment may be combined with each other, but it must be premised that those skilled in the art can implement it. When the combination of technical means is contradictory to each other or impossible to implement, such a combination of technical means does not exist and is considered not to belong to the scope of the claims of the present invention. 【0025】 The present invention provides a golf practice net. 【0026】 As shown in Figures 1 to 9, in the embodiment of the present invention, the golf practice net comprises a support rod 10 and a support frame 20. 【0027】 Specifically, the support frame 20 includes a mounting base 21, a slide base 22, a plurality of first connecting rods 23, a plurality of second connecting rods 24, a plurality of third connecting rods 25, a plurality of fourth connecting rods 26, and a net cloth 27. The mounting base 21 is slidably mounted on one end of the support rod 10, a plurality of first mounting portions are provided on the circumferential side of the mounting base 21, and the plurality of first mounting portions are spaced apart along the circumferential direction of the mounting base 21. The slide base 22 is fitted onto the support rod 10 and is slidable relative to the connecting rod, a plurality of second mounting portions are provided on the circumferential side of the slide base 22, and the plurality of second mounting portions are spaced apart along the circumferential direction of the slide base 22. 【0028】 One end of each first connecting rod 23 is rotatably attached to one first mounting part, the other end of each first connecting rod 23 is rotatably attached between the ends of each second connecting rod 24, one end of each third connecting rod 25 is rotatably attached to one second mounting part, the other end of each third connecting rod 25 is rotatably attached between the ends of each first connecting rod 23, one end of each fourth connecting rod 26 is rotatably attached between the ends of each third connecting rod, the other end of each fourth connecting rod 26 is rotatably connected to the end of the second connecting rod 24 closest to the first connecting rod 23, and the net The netcloth 27 is connected to a plurality of second connecting rods, and the support frame 20 further has a first deployed state, a second deployed state and a retracted state. In the first deployed state, the plurality of first connecting rods 23, a plurality of second connecting rods 24, a plurality of third connecting rods 25, a plurality of fourth connecting rods 26 and the netcloth 27 are deployed opposite each other, and the netcloth 27 forms a hitting surface for striking a golf ball. In the second deployed state, the netcloth 27 is curved. In the retracted state, the plurality of first connecting rods 23, a plurality of second connecting rods 24, a plurality of third connecting rods 25, a plurality of fourth connecting rods 26 and the netcloth 27 are constricted to the outside of the support rods 10. Here, the netcloth 27 has a certain rebound elasticity, and when a golf ball is struck against the netcloth 27, the netcloth 27 can cause the golf ball to rebound, allowing the user to quickly pick up the struck golf ball. 【0029】 The slide base 22 has a first lock position, a second lock position, and a retracted position, with the second lock position located between the first lock position and the retracted position. In the first lock position, the slide base 22 is positioned close to the mounting base 21 so that the support frame 20 is fixed in a first extended state. In the second lock position, the slide base 22 is positioned close to the mounting base 21 so that the support frame 20 is fixed in a second extended state. In the unlock position, the slide base 22 is positioned away from the mounting base 21 so that the support frame 20 is in a retracted state. 【0030】 In other words, as the user moves the slide base 22 to the first lock position, the multiple first connecting rods 23, multiple second connecting rods 24, multiple third connecting rods 25, multiple fourth connecting rods 26 and the net cloth 27 gradually unfold, and when the slide base 22 moves to the first lock position, the multiple first connecting rods 23, multiple second connecting rods 24, multiple third connecting rods 25, multiple fourth connecting rods 26 and the net cloth 27 are fully unfolded, and the net cloth 27 forms a hitting surface for striking the golf ball. 【0031】 To make it easier to understand, when the slide base 22 is in the first locked position, the support frame 20 is in the first unfolded state, in which case the multiple first connecting rods 23, multiple second connecting rods 24, multiple third connecting rods 25, multiple fourth connecting rods 26 and net cloth 27 are in the fully unfolded state, and when the slide base 22 is in the second locked position, the support frame 20 is in the second unfolded state, and the second locked position is downstream of the first locked position, that is, the support frame When the M20 is in the first unfolded state, the multiple first connecting rods 23, multiple second connecting rods 24, multiple third connecting rods 25, multiple fourth connecting rods 26, and the net cloth 27 are in a half-unfolded state. In this case, the first connecting rods 23 and the second connecting rods 24 are positioned at an obtuse angle, the central part of the net cloth 27 is positioned as a plane, and the peripheral side of the net cloth 27 is positioned as an inclined surface, that is, the net cloth 27 is curved. In other words, when in the second unfolded state, only the central part of the net cloth 27 forms the hitting surface, that is, the hitting area of ​​the net cloth 27 is reduced. 【0032】 As the user moves the slide base 22 from the first or second lock position to the storage position, the multiple second connecting rods 24, multiple third connecting rods 25, multiple fourth connecting rods 26 and the net cloth 27 narrow toward the support rod 10, and when the slide base 22 moves to the storage position, the multiple second connecting rods 24, multiple third connecting rods 25, multiple fourth connecting rods 26 and the net cloth 27 narrow toward the outside of the support rod 10. 【0033】 Specifically, in actual use, if the user is a beginner, the slide base 22 can be slid to the first lock position so that the entire surface of the net cloth 27 forms the hitting surface. In this case, the golf practice net can be placed on the ground and supported by the connecting rod to perform practice. 【0034】 After the user has practiced for a certain period of time and improved their golf skills, the user can slide the slide base 22 to the second lock position during practice, causing the net cloth 27 to curve and forming a hitting surface only in the central part of the net cloth 27. This reduces the hitting area of ​​the net cloth 27, increasing the difficulty of the user's practice and enhancing the effectiveness of the user's practice. 【0035】 After use, the slide base 22 needs to be slid from the first or second lock position to the storage position so that the multiple first connecting rods 23, multiple second connecting rods 24, multiple third connecting rods 25, multiple fourth connecting rods 26 and the net cloth 27 can slide onto the support rod 10. After sliding to the storage position, the multiple first connecting rods 23, multiple second connecting rods 24, multiple third connecting rods 25, multiple fourth connecting rods 26 and the net cloth 27 can be completely retracted, allowing the golf practice net to be stored and effectively reducing the space occupied by the golf practice net. 【0036】 Furthermore, the basic needs of a support and expansion structure can be met simply by having the first connecting rod 23, the second connecting rod 24, and their connection relationships with the third connecting rod 25 and the fourth connecting rod 26. By providing the third connecting rod 25 and the fourth connecting rod 26, the support and expansion structure becomes more three-dimensional and stable. In contrast, the installation of the slide base is also due to the need for more accurate and stable structural positioning. 【0037】 It does not require assembly or attachment during use, nor does it require disassembly or removal after use, thus improving ease of use for the user. Furthermore, since the golf practice net of this invention can be used without assembling any parts, it avoids the problem of losing parts that can occur when attaching or detaching a golf practice net. 【0038】 In the technical means of the present invention, a mounting base 21 of a support frame 20 is attached to one end of a support rod 10, a plurality of first mounting portions are provided on the circumferential side of the mounting base 21, the plurality of first mounting portions are spaced apart along the circumferential direction of the mounting base 21, a slide base 22 is fitted onto the support rod 10 and is slidable relative to the connecting rod, a plurality of second mounting portions are provided on the circumferential side of the slide base 22, the plurality of second mounting portions are spaced apart along the circumferential direction of the slide base 22, one end of each first connecting rod 23 is rotatably attached to one first mounting portion, and the other end of each first connecting rod 23 is attached to each second connecting rod The net cross 27 is connected to a plurality of second connecting rods, with the net cross 27 rotatably mounted between the ends of the groove 24, one end of each third connecting rod 25 rotatably mounted to one second mounting point, the other end of each third connecting rod 25 rotatably mounted between the ends of each first connecting rod 23, one end of each fourth connecting rod 26 rotatably mounted between the ends of each third connecting rod, and the other end of each fourth connecting rod 26 rotatably connected to the end of the second connecting rod 24 closest to the first connecting rod 23. The support frame 20 has a first deployed state, a second deployed state, and a retracted state. In the first deployed state, a plurality of first connecting rods 23, a plurality of second connecting rods 24, a plurality of third connecting rods 25, a plurality of fourth connecting rods 26, and a net cloth 27 are deployed opposite each other, and the net cloth 27 forms a hitting surface for striking a golf ball. In the second deployed state, the net cloth 27 is curved. In the retracted state, the plurality of first connecting rods 23, a plurality of second connecting rods 24, a plurality of third connecting rods 25, a plurality of fourth connecting rods 26, and a net cloth 27 are tapered outwards from the support rod 10.The slide base 22 has a first lock position, a second lock position, and a storage position, with the second lock position located between the first lock position and the storage position. When in the first lock position, the support frame 20 is fixed in the first extended state; when in the second lock position, the support frame 20 is fixed in the second extended state; and when in the unlock position, the support frame 20 is in the stored state. As a result, if the user is a beginner golfer, sliding the slide base 22 to the first lock position allows the entire surface of the net cloth 27 to be used as a hitting surface. In this case, the golf practice net can be placed on the ground and supported by the connecting rod to perform practice. After the user has practiced for a certain period of time and improved their golf skills, when the user practices again, sliding the slide base 22 to the second lock position allows the net cloth 27 to be folded, creating a hitting surface only in the center of the net cloth 27. This reduces the hitting area of ​​the net cloth 27, increasing the difficulty of the user's practice and enhancing the effectiveness of the user's practice, thus effectively improving the practicality of the golf practice net. 【0039】 In some embodiments, the golf practice net further comprises two first shielding plates 30, both of which are attached to the side of the net cloth 27 away from the second connecting rod 24, with the two first shielding plates 30 provided on opposite sides of the net cloth 27, extending away from the net cloth 27, and the two first shielding plates 30 being detachably provided. 【0040】 Specifically, before practice, the user attaches two first shielding plates 30 to opposite sides of the net cloth 27, thereby shielding both sides of the net cloth 27. This allows the first shielding plates 30 on both sides to shield the golf ball when it bounces, preventing it from flying off the sides of the net cloth 27. This allows the golf ball to bounce back to the user's hitting position. At this point, the bounced golf ball approaches the user's hitting position, allowing the user to quickly pick up the golf ball and hit again. Therefore, it does not affect the user's touch when picking up balls from long distances, effectively enhancing the user's practice experience. The two first shielding plates 30 can be attached to the net cloth 27 with adhesive. In other embodiments, the golf practice net does not need to have the first shielding plates 30. 【0041】 The first shielding plates 30 on both sides effectively create a large practice space, ensuring effective practice. At the same time, to ensure accuracy during practice and storage of equipment, the first shielding plates 30 may be detachably attached to the net cloth 27. Furthermore, while providing at least one first shielding plate 30 on each side is sufficient to meet usage needs, multiple plates may be provided depending on the structural requirements to provide a more flexible batting practice space. For example, multiple plates may be combined using a retractable or folding method. 【0042】 In some embodiments, the golf practice net further comprises a second shielding plate 70 which is movably attached to the net cloth 27, the second shielding plate 70 extending away from the net cloth 27, forming a shielding surface for shielding golf balls, and the shielding surface is parallel to the hitting surface. 【0043】 Specifically, if the user is a beginner, the second shielding plate 70 may be attached to the net cross 27. This way, when a golf ball is hit but does not reach the net cross 27 and lies within the shielding range of the second shielding plate 70, the second shielding plate 70 will block the golf ball, causing it to fly far away and preventing loss or increasing the time the user spends retrieving the ball. Furthermore, as the user's skill level increases, the second shielding plate 70 can be removed from the net cross 27 to increase the difficulty of the user's practice. This can significantly improve the user experience. 【0044】 Specifically, the second shielding plate 70 can be attached to either side of the net cloth 27. Users can selectively attach it according to the direction in which they hit their golf ball. For example, if the golf ball hit by the user is biased to the left, the second shielding plate 70 can be attached to the left side of the net cloth 27; if the golf ball hit is biased to the right, the second shielding plate 70 can be attached to the right side of the net cloth 27; and if the golf ball hit is biased towards the higher side, the second shielding plate 70 can be attached to the upper side of the net cloth 27. Specifically, it can be installed according to the actual situation. The present invention does not specifically limit this. 【0045】 In another embodiment, the second shielding plate 70 is provided on the upper side and both sides of the net cloth 27, and the second shielding plate 70 extends away from the net cloth 27, forming a shielding surface for shielding golf balls. In other words, the second shielding plate 70 shields three sides excluding the bottom side. In other embodiments, the golf practice net is not provided with the second shielding plate 70. Here, the second shielding plate 70 may be attached to the net cloth 27 with adhesive. In other embodiments, the golf practice net is not provided with the second shielding plate 70. 【0046】 In some embodiments, the golf practice net further comprises fixing nails 40, which are attached to the end of the support rod 10 away from the mounting base 21 and are elongated in shape, extending away from the support rod 10, and are used to insert into the ground. 【0047】 Specifically, when the golf practice net is placed on the ground, fixing nails 40 can be inserted into the ground. This fixes the position of the golf practice net, preventing it from shifting when a golf ball hits the net cross 27 during practice, thus contributing to an improved user experience. In other embodiments, fixing nails 40 are not provided on the golf practice net. 【0048】 In some embodiments, the support rod 10 is engaged and connected to the fixing nail 40. Regarding the specific engagement method, methods such as engagement slots, engagement protrusions, engagement buckles, and elastic buckles can be flexibly provided according to the connection structure, and other flexible connection methods such as inserts and turnbuckles also fall within the scope of engagement methods as defined herein. 【0049】 In some embodiments, an engaging projection is provided at the end of the support rod 10 away from the mounting base 21, an engaging portion 41 is provided on the circumferential side of the fixing nail 40, an engaging slot is provided in the engaging portion 41, and the engaging slot and the engaging projection are engaged and matched. 【0050】 Specifically, the fixing nail 40 is detachably attached to the support rod 10. When a user practices golf, they can engage the fixing nail 40 with the end of the support rod 10 away from the mounting base 21, and then insert the fixing nail 40 into the ground to secure it. After practice is complete, the fixing nail 40 can be removed from the support rod 10 and stored. This prevents the fixing nail 40 from causing damage to the user and enhances safety during use. In other embodiments, the fixing nail 40 may be attached to the support rod 10 via a screw fixing bracket. 【0051】 In some embodiments, the support rod 10 includes a connecting handle 11 and a sleeve 50, wherein a mounting base 21 is attached to one end of the connecting handle 11, the connecting handle 11 is hollow and forms a mounting passage 1112a, the mounting passage 1112a forms a mounting opening on the end face of the mounting base 11 away from the mounting base 21, the outer circumferential surface of the sleeve 50 is provided with a folded edge 52 which forms an engaging projection, the sleeve 50 is inserted into the mounting passage 1112a through the mounting opening, the sleeve 50 comprises a mounting cavity, the mounting cavity forms a first opening at the end of the sleeve 50 away from the folded edge 52, and the mounting cavity is for housing a fixing nail 40. 【0052】 Specifically, after practice is complete, the sleeve 50 can be removed from the mounting passage 1112a, the fixing nails 40 can be inserted into the mounting cavity and stored, and then the sleeve 50 can be inserted into the mounting passage 1112a and stored. This eliminates the need to store the fixing nails 40 individually with other devices, avoiding the problem of loss due to individual storage and improving the user experience. In other embodiments, the support rod 10 may not be provided with a sleeve 50, and the fixing nails 40 may be directly inserted into the mounting passage 1112a for storage. 【0053】 In some embodiments, a second opening 51 is provided in the side wall of the sleeve 50, the second opening 51 communicates with a mounting cavity, a first elastic engagement projection 53 is provided in the second opening 51, the connecting handle 11 is provided with a stopper engagement slot corresponding to the second opening 51, and the first elastic engagement projection 53 is elastically engaged with the stopper engagement slot. 【0054】 Specifically, when the sleeve 50 is inserted into the mounting passage 1112a, the first elastic engaging projection 53 elastically engages with the stopper engaging slot, fixing the sleeve 50 in place within the mounting passage 1112a. If the user wishes to remove the sleeve 50 from the mounting passage 1112a, they can push the first elastic engaging projection 53 to disengage it from the stopper engaging slot. In this case, applying a tensile force to the sleeve 50 allows it to be removed from the mounting passage 1112a. This method is simple and convenient and contributes to reducing the difficulty of production. In other embodiments, threads may be provided on the outer surface of the sleeve 50, or threads may be provided on the passage wall of the mounting passage 1112a, and the sleeve 50 may be screwed into the mounting passage 1112a. 【0055】 In some embodiments, the connecting handle 11 includes a connecting segment 112 and a support segment 111, wherein a mounting base 21 is attached to one end of the connecting segment 112, the other end of the connecting segment 112 is rotatably connected to the support segment 111, and the support segment 111 is hollow and forms a mounting passage 1112a. 【0056】 Specifically, during use, the user can rotate the support segment 111 or the connecting segment 112 so that the support segment 111 and the connecting segment 112 form an arch structure. This allows the length of the connecting handle 11 to be shortened, contributing to a reduction in the space occupied by the golf practice net. In other embodiments, the support segment 111 and the connecting segment 112 may be fixedly connected. 【0057】 In some embodiments, the support segment 111 includes a first segment 1111 and a second segment 1112, where one end of the first segment 1111 is rotatably connected to a connecting segment 112, the second segment 1112 is hollow and forms a mounting passage 1112a, the mounting passage 1112a passes through both ends of the second segment 1112, and the other end of the first segment 1111 extends into and is extendable from the mounting passage 1112a. The golf practice net further includes a locking mechanism 60, which connects the first segment 1111 and the second segment 1112 and is used to lock the first segment 1111 and the second segment 1112 together. 【0058】 Specifically, a portion of the first segment 1111 extends into the mounting passage 1112a and is expandable and contractible from the mounting passage 1112a. When the first segment 1111 extends out of the mounting passage 1112a, the length of the support segment 111 can be increased, and conversely, when the first segment 1111 retracts into the mounting passage 1112a, the length of the support segment 111 can be shortened. In other words, during use, the user can adjust the length of the support segment 111 by adjusting the expansion and contraction of the first segment 1111, thereby meeting the usage needs of different users. Alternatively, when the user is using it, they can apply a tensile force to the first segment 1111 to extend it out of the mounting passage 1112a to meet the user's desired length. When the user is storing it, they can apply a thrust to the first segment 1111 to retract it into the mounting passage 1112a to reduce the space it occupies. After the user adjusts the required length, the locking mechanism 60 locks the first segment 1111 and the second segment 1112 together, fixing them in place and preventing loosening. In other embodiments, the first segment 1111 and the second segment 1112 may be permanently connected. 【0059】 In some embodiments, a plurality of stopper slots 1111a are recessed in the side wall of the first segment 1111, and the plurality of stopper slots 1111a are spaced apart along the length of the first segment 1111. A third opening is provided in the side wall of the second segment 1112, the third opening corresponds to one of the stopper slots 1111a, and a second elastic engagement projection 1112b is provided in the third opening, the second elastic engagement projection 1112b has a stopper position and an unlock position, in the stopper position the second elastic engagement projection 1112b extends into the stopper slot 1111a, and in the unlock position the second elastic engagement projection 1112b moves away from the stopper slot 1111a. 【0060】 The locking mechanism 60 comprises a fixed base 61 and a contact member 62. The fixed base 61 is provided with a movable slot and mounting holes. The movable slot penetrates both opposing sides of the fixed base 61, and the mounting holes penetrate the side walls of the movable slot. The contact member 62 includes a hinge portion 622, contact portions 621 provided on both opposing sides of the hinge portion 622 corresponding to mounting holes that pivotally connect within the movable slot, and a rotating portion 623. The hinge portion 622 is hinge-connected within the movable slot, the contact portions 621 are installed corresponding to the mounting holes, and the rotating portion 623 is provided outside the movable slot. The contact member 62 has a contact state and a release state. In the contact state, the contact portion 621 abuts against one side of the second elastic engagement projection 1112b, and in the release state, the contact portion 621 is separated from the second elastic engagement projection 1112b. 【0061】 Specifically, if it is necessary to adjust the length of the support segment 111, the turning part 623 can be turned clockwise to move the contact member 62 from the contact state to the release state, and the second elastic engagement projection 1112b can be repelled by elastic force towards the opening. In this case, the user can adjust the length of the support segment 111 by applying tensile or thrust force to the first segment 1111. 【0062】 When the user adjusts the support segment 111 to the desired length, the adjacent stopper slot 1111a moves to the third opening to accommodate it. In this case, the user rotates the turning part 623 counterclockwise, moving the contact member 62 from the released state to the contact state, and the second elastic engaging projection 1112b extends into the stopper slot 1111a due to the contact and push of the contact member 62. The contact between the side of the second elastic engaging projection 1112b and the slot wall of the stopper slot 1111a prevents the expansion and contraction of the first segment 1111. This results in a simple structure for the locking mechanism 60, reliable operation, and contributes to reducing the difficulty of manufacturing. 【0063】 In other embodiments, the first segment 1111 is provided with a plurality of first insertion holes, which are spaced apart along the length of the first segment 1111; the second segment 1112 is provided with a plurality of second insertion holes, which are spaced apart along the length of the second segment 1112; the plurality of first insertion holes and the plurality of second insertion holes correspond one-to-one; the locking mechanism 60 includes a pin, which can be inserted into either the first or second insertion hole. 【0064】 In some embodiments, the first segment 1111 is hollow and forms a cavity, the cavity forming a first through-hole in the side wall of the first segment 1111, and an elastic projection is provided in the first through-hole, and a plurality of second through-holes are provided in the side wall of the second segment 1112, the plurality of second through-holes are spaced apart along the length of the second segment 1112, and a stopper projection can elastically extend out of any of the through-holes. 【0065】 Specifically, when a user applies a tensile or thrust force to the first segment 1111, the elastic projection extends from the through-hole, providing damping for the expansion and contraction of the first segment 1111, preventing the user from directly pulling the first segment 1111 out of the mounting passage 1112a, and thus enhancing the user experience. 【0066】 In some embodiments, a ball receiving hole is provided in the center of the net cloth 27, and a net pocket is provided on the side of the net cloth 27 facing the second connecting rod 24, with the net pocket positioned to correspond to the ball receiving hole. The golf ball can fall through the ball receiving hole into the net pocket. In other words, the user can practice aligning the golf ball with the ball receiving hole, enabling more accurate ball striking practice and effectively enhancing the user's practice effectiveness. In other embodiments, the net cloth 27 does not have a ball receiving hole. 【0067】 The foregoing are merely preferred embodiments of the present invention and do not limit the scope of the claims of the present invention. Any transformation of equivalent structures or direct / indirect application to other related technical fields using the contents of the specification and drawings of the present invention under the concept of the present invention are all included within the scope of the claims of the present invention.
