Detailed implementation manners

[0030] The technical solution provided by the present invention will be further described below with reference to the accompanying drawings.

[0031] As Figures 1 to 14As shown in the figure, a multifunctional tennis net includes a main body bracket 1. The main body bracket 1 includes a supporting bottom rod 102. A net support rod 101 is slidably installed in the supporting bottom rod 102. The upper and lower halves of the net support rod 101 are respectively provided with transverse chutes. A sliding mechanism 2 is rotatably installed in the chutes. The sliding mechanism 2 includes a movable rod 201. The movable rod 201 is rotatably installed in the sliding chute of the net support rod 101. A chute is provided in the movable rod 201. A moving slider 202 is slidably installed in the chute of the movable rod 201. Springs are fixedly installed between the two sides of the moving slider 202 and the movable rod 201 respectively. A short cylindrical rod is fixedly installed on the moving slider 202. The short cylindrical rod on the moving slider 202 is slidably matched with the chute on the net support rod 101. When the movable rod 201 is at a horizontal angle, the chute in the movable rod 201 and the chute on the net support rod 101 are at the same angle, so that the moving slider 202 can slide freely in the movable rod 201. When the movable rod 201 is at a vertical angle, the chute on the movable rod 201 and the chute on the net support rod 101 are perpendicular to each other, so that the cylindrical rod on the moving slider 202 is at the intersection of the two chutes, making the moving slider 202 unable to slide on the movable rod 201, which is used to fix the position of the moving slider 202. A cylindrical groove is provided on the moving slider 202. The sliding mechanism 2 includes a clamping rod 203. Cylindrical keys are fixedly installed on the upper and lower halves of the outer side of the clamping rod 203 respectively. The cylindrical keys on the clamping rod 203 are rotatably matched with the cylindrical groove on the moving slider 202. A net 3 is clamped and installed between the two clamping rods 203. The net 3 is clamped and supported by the two clamping rods 203. When playing tennis on a windy day outdoors, by rotating the movable rod 201 to a horizontal angle, the moving slider 202 can slide in the movable rod 201. The wind pushes the net 3 to drive the moving slider 202 to slide downward in the movable rod 201 in the downwind direction, making the player in the downwind direction closer to the net 3. When the player in the downwind direction hits the ball against the wind, the tennis ball is more likely to cross the net. The moving distance of the net is controlled by the magnitude of the wind force, making the tennis activities on a windy day more fair.

[0032] As Figures 1 to 14As shown in the figure, positioning grooves are provided at the left and right ends of the movable rod 201. A pair of second positioning sliders 108 are longitudinally and slidably installed in the middle part of the net support rod 101. A tension spring is fixedly installed between the second positioning slider 108 and the net support rod 101. The second positioning slider 108 is slidably engaged with the positioning groove on the movable rod 201, which is used to fix the rotation angle of the movable rod 201. When used in outdoor windless weather or indoors, the movable rod 201 is fixed at a vertical angle to fix the position of the net 3, facilitating the normal use of the net 3. A rectangular groove is provided in the second positioning slider 108, and an inclined groove is provided in the rectangular groove of the second positioning slider 108. A pair of adjusting rods 109 are transversely and slidably installed in the middle part of the net support rod 101. The adjusting rod 109 is slidably engaged with the rectangular groove on the second positioning slider 108. A cylindrical key is fixedly installed on the adjusting rod 109, and the cylindrical key on the adjusting rod 109 is slidably engaged with the inclined groove on the second positioning slider 108. The second positioning slider 108 is driven by the tension spring to slide in the net support rod 101 and cooperate with the positioning groove on the movable rod 201. When the angle of the movable rod 201 needs to be adjusted, by pressing the adjusting rod 109, the cylindrical key on the adjusting rod 109 cooperates with the inclined groove in the second positioning slider 108 to drive the second positioning slider 108 to slide reversely on the net support rod 101, so that the second positioning slider 108 no longer cooperates with the positioning groove on the movable rod 201, and the movable rod 201 can be rotated and adjusted in angle on the net support rod 101.

[0033] As Figures 1 to 14 shown in the figure, a plurality of first positioning sliders 107 are transversely and slidably installed on the net support rod 101. A compression spring is fixedly installed between the first positioning slider 107 and the net support rod 101. The first positioning slider 107 is slidably installed at the upper and lower ends of the chute on the net support rod 101. The upper and lower sides of the first positioning slider 107 are respectively in contact and cooperation with the upper and lower sides of the movable rod 201, which is used to fix the angle of the movable rod 201 at a horizontal angle when the movable rod 201 is in a horizontal angle.

[0034] As Figures 1 to 14 shown in the figure, the net 3 includes a nylon net 301. The nylon net 301 is clamped and installed between two clamping rods 203 and fixed by fixing bolts 204. A pair of closing zippers 302 are provided on both the upper and lower sides of the nylon net 301. When storing the net, the racket and tennis balls are wrapped by folding the net in half, and the upper and lower sides of the net are respectively closed by the closing zippers 302. Other tennis equipment is uniformly stored while folding and storing the net, which is convenient for timely access during use.

[0035] As Figures 1 to 14As shown in the figure, a hollow connection block 103 is fixedly installed on the outside of the support bottom rod 102. A third positioning slider 111 is horizontally slidably installed in the hollow connection block 103 on the outside of one of the support bottom rods 102. A compression spring is fixedly installed between the third positioning slider 111 and the hollow connection block 103. A pair of positioning pawls 112 are longitudinally slidably installed at the front end of the third positioning slider 111. A compression spring is fixedly installed between the positioning pawl 112 and the third positioning slider 111. When the net is folded and stored, the two support bottom rods 102 are combined. The positioning pawls 112 on the third positioning slider 111 are engaged with the ratchet teeth of another hollow connection block 103 to fix the two support bottom rods 102 together, which is convenient for storage and handling. When the net is needed, by pressing the two positioning pawls 112 to make them approach each other, the positioning pawls 112 no longer cooperate with the hollow connection block 103, and the two support bottom rods 102 are separated for placement and use.

[0036] As Figures 1 to 14 shown, an adjusting screw rod 110 is longitudinally rotatably installed in the support bottom rod 102. The net support rod 101 is in screw thread fit with the adjusting screw rod 110. A rocker 104 is horizontally rotatably installed at the bottom of the support bottom rod 102. A bevel gear is fixedly installed on the rocker 104. The adjusting screw rod 110 is fixedly installed with a bevel gear at the bottom. The bevel gear at the bottom of the adjusting screw rod 110 is meshed with the bevel gear on the rocker 104. By rotating the rocker 104, the adjusting screw rod 110 is driven to rotate, which is used to adjust the height of the net support rod 101 on the support bottom rod 102, so as to facilitate the adjustment of the height of the net 3.

[0037] As Figures 1 to 14As shown in the figure, on both sides of the bottom of the supporting bottom rod 102, there are horizontally rotatably installed supporting bottom plates 105. The supporting bottom plates 105 are used to support the supporting bottom rod 102. On the supporting bottom plates 105, there are rotatably installed connecting rods 106. At the top of the connecting rods 106, there are fixedly installed cylindrical keys. On both sides of the bottom of the supporting bottom rod 102, there are longitudinally arranged chutes. The cylindrical keys at the top of the connecting rods 106 are in sliding fit with the chutes at the bottom of the supporting bottom rod 102. Horizontally slidably installed on the bottom of the supporting bottom rod 102 is a fourth positioning slider 113. Between the fourth positioning slider 113 and the supporting bottom rod 102, there is fixedly installed a compression spring. The bottom of the fourth positioning slider 113 is in contact and cooperation with the top of the connecting rod 106. By the fourth positioning slider 113, the sliding of the cylindrical keys on the connecting rods 106 in the chutes at the bottom of the supporting bottom rod 102 is restricted, so that the supporting bottom plates 105 maintain an angle perpendicular to the supporting bottom rod 102, facilitating the supporting bottom plates 105 to support the supporting bottom rod 102. When it is necessary to store the ball net, by pressing the fourth positioning slider 113, the fourth positioning slider 113 retracts into the supporting bottom rod 102 and no longer contacts the connecting rod 106, enabling the cylindrical keys at the top of the connecting rod 106 to slide in the chutes at the bottom of the supporting bottom rod 102, allowing the supporting bottom plates 105 to rotate at the bottom of the supporting bottom rod 102, and making the supporting bottom plates 105 fit with the supporting bottom rod 102, facilitating storage.

[0038] Working principle: When it is necessary to carry out tennis activities outdoors, first open the closing zipper 302 so that the upper and lower ends of the nylon net 301 are no longer closed. Then press the two pairs of positioning pawls 112 to separate the two supporting bottom rods 102. Then rotate the supporting bottom plates 105 to an angle perpendicular to the supporting bottom rods 102, and place the supporting bottom rods 102 vertically at the required position. Then rotate the rocker 104 as needed to adjust the height of the ball net 3, and it can be used normally.

[0039] When encountering windy weather, by pressing the two adjusting rods 109, the second positioning slider 108 no longer restricts the rotation of the movable rod 201. Rotate the movable rod 201 to a horizontal angle, so that the first positioning slider 107 pops up through the compression spring to fix the angle of the movable rod 201, enabling the ball net 3 to slide downward along the wind direction on the movable rod 201 by the push of the wind, making the distance between the players in the downwind direction and the nylon net 301 closer, facilitating the players in the downwind direction to hit the ball over the net and making it more fair when carrying out activities in windy weather.

[0040] When the activity ends, press the first positioning slider 107 to retract it into the net support rod 101. Then rotate the movable rod 201 to a vertical angle and fix it with the second positioning slider 108. Then press the fourth positioning slider 113 to press it into the support bottom rod 102, so that the support bottom plate 105 rotates and fits against the bottom of the support bottom rod 102 to lay down the net. Then place the racket and other sports equipment in the nylon net 301. Then fold the nylon net 301 in half and close the closing zippers 302 at both the upper and lower ends to store the sports equipment in the nylon net 301. Then press the third positioning slider 111 in the hollow connecting block 103 to make the positioning pawl 112 engage with the ratchet teeth of the hollow connecting block 103 on another support bottom rod 102 to fix the two support bottom rods 102 together for storage.
