Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides an embodiment: a basketball stand with adjustable height for basketball training comprises a base 1, wherein a first fixed cavity 2 and a second fixed cavity 3 are sequentially welded at the upper end of the base 1 from left to right, threaded sleeves 4 are arranged in the first fixed cavity 2 and the second fixed cavity 3 through bearings, belt pulleys 6 are fixed at the bottoms of the two threaded sleeves 4, the two belt pulleys 6 are connected through a belt 7, openings matched with the belt 7 are formed in the inner walls of the first fixed cavity 2 and the second fixed cavity 3, a first bevel gear 8 is fixed at the upper end of the threaded sleeve 4 at the left side, a second bevel gear 25 is meshed with the first bevel gear 8, a third connecting rod 26 is welded on the front side wall of the second bevel gear 25, the third connecting rod 26 is connected with the inner wall at the front side of the first fixed cavity 2 through a bearing, a crank 27 is welded at the third connecting rod 26 passing through the front end of the first fixed cavity 2, all threaded connection has threaded rod 5 in two threaded sleeve pole 4, the distance that two threaded rod 5 moved on threaded sleeve pole 4 equals, its effect can be at horizontal rebound for guaranteeing that bracing piece 10, connect through head rod 9 between the upper end of two threaded rod 5, it is fixed for connecting two threaded rod 5, let two threaded rod 5 more firm at the in-process that removes, the top of two threaded rod 5 all welds on bracing piece 10, the top welding of bracing piece 10 has mount 11, the vertical welding of the lower part of bracing piece 10 left end has backboard 13, and pass through second connecting rod 12 fixed connection between backboard 13's top and the bracing piece 10, the welding has connecting block 14 on the bracing piece 10 of backboard 13 right side tip top, and the left side welding of connecting block 14 has first link 15.

A second connecting frame 16 is fixed at one end of the first connecting frame 15 penetrating through the backboard 13, telescopic rods 17 are symmetrically arranged between the second connecting frame 16 and the first connecting frame 15, the telescopic rods 17 are telescopic hollow cylindrical rods formed by rolling metal strips or plastic sheets, and the telescopic rod is characterized in that the metal strips or plastic sheets are pre-shaped into elastic curling layers with memory function and smaller than the outer diameter of the rod body, so that the elastic curling layers have self-tightening function, the curling layers always have elastic potential energy for applying pressure on the telescopic rods, first strong springs 18 are sleeved on the two telescopic rods 17, the upper ends and the lower ends of the first strong springs 18 are fixed on the telescopic rods 17, a basket 19 is welded at the left side of the second connecting frame 16, a basket net 20 is arranged below the second connecting frame 19, clamping rods 21 are equally connected at the bottom ends of the basket 19 through hinge shafts 23, and the clamping rods 21 and the basket 19 are connected through the hinge shafts 23, all welded between the inner wall of clamping bar 21 has second powerful spring 24, the bottom of clamping bar 21 has all buckled the cable loop 22, its bottom laminating of effect for guaranteeing clamping bar 21 is inseparable, thereby guarantee when the device normal use, cable loop 22 can not fall out from clamping bar 21, and cable loop 22 all installs on basket net 20, basket net 20 and cable loop 22 formula structure as an organic whole, its cooperation that is used for through clamping bar 21, cable loop 22 and articulated shaft 23 is used, simplify basket net 20's installation and the operation process who dismantles, it is more simple and convenient to make basket net 20 install and dismantle, time saving and labor saving.

The working principle is as follows: when the device is normally used, when the height of the basket 19 needs to be increased according to training requirements, the rotary crank 27 drives the third connecting rod 26 at the rear side to rotate, the third connecting rod 26 rotates to drive the second bevel gear 25 to rotate, so as to drive the first bevel gear 8 meshed with the second bevel gear 25 to rotate, the first bevel gear 8 rotates to drive the left threaded sleeve rod 4 fixedly connected with the first bevel gear to rotate, so as to drive the threaded rod 5 connected with the threads of the threaded sleeve rod 4 to rotate, the left threaded sleeve rod 4 rotates to simultaneously drive the left belt pulley 6 to rotate, the left belt pulley 6 rotates to drive the belt 7 to rotate, the belt 7 rotates to drive the right belt pulley 6 to rotate, the right belt pulley 6 rotates to drive the right threaded sleeve rod 4 to rotate, so as to drive the right threaded rod 5 in threaded connection with the right threaded sleeve rod 4 to rotate, so as to simultaneously move upwards through the two threaded rods 5 fixedly connected with, the support rod 10 fixedly connected with the support rod is driven to move upwards, so that the basket 19 fixedly connected with the support rod 10 is driven to move upwards, and the crank 27 is rotated reversely when the basket 19 needs to be lowered.

When the basket is buckled by an athlete, the athlete generally takes the basket 19 down, so that a downward pulling force is applied to the basket 19, the downward pulling force acts on the second connection frame 16 through the basket 19, the second connection frame 16 is pulled to apply a downward pressure to the two expansion rods 17 fixed inside the second connection frame 16, the expansion rods 17 retract downwards after being pressed downwards, so that the first strong springs 18 fixed on the expansion rods 17 are compressed, the first strong springs 18 are compressed and deformed to generate an upward reaction force, the pulling force applied to the second connection frame 16 is indirectly resisted and reduced, and the second connection frame 16 after the basket is buckled by the athlete is restored to the original position.

After the device is used for a long time, when the basket 20 is damaged and needs to be replaced, the clamping rod 21 is in an annular shape, after the basket 19 is lowered, only an outward pulling force needs to be applied to two sides of the clamping rod 21 respectively by hands, two ends of the clamping rod 21 are enabled to rotate towards two sides through the hinge shaft 23 in the middle position of the top end of the clamping rod, two bottom ends of the clamping rod 21 are separated by a certain distance, the rope buckles 22 buckled on the clamping rod 21 are taken out, all the rope buckles 22 buckled on the clamping rod 21 are sequentially taken out, the basket 20 is separated from the basket 19, after a new basket 20 is replaced, two bottom ends of the clamping rod 21 are separated by a certain distance sequentially, then the rope buckles 22 on the replaced basket 20 are sequentially buckled in the clamping rod 21, and the basket 20 and the basket 19 are fixedly connected again.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
