DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] The terms "left, right, upper, lower" etc. of the present invention are relative to Figure 1 the positional relationship shown.

[0025] Embodiment 1

[0026] As shown in Figure 1 and 2As shown in FIGS. 3 and 4, a table tennis net rack with adjustable tension includes a left support 1 and a right support 2 arranged opposite to each other. The left support 1 is fixed to the left side of the table tennis table, and the right support 2 is fixed to the right side of the table tennis table. A vertical left bracket 3 is fixed to the upper end of the left support 1. A left wheel frame 5 is arranged at the upper end of the left bracket 3. A left connecting bolt 6 is fixed to the lower end of the left wheel frame 5. The left connecting bolt 6 passes through the top of the left bracket 3 and is threadedly connected with a locking nut. A left idler wheel 4 is connected to the left wheel frame 5.

[0027] A vertical right bracket 7 is fixed to the upper end of the right support 2. A right wheel frame 8 is arranged at the upper end of the right bracket 7. A suspension ring is fixed to the right side of the upper end of the right wheel frame 8. The right end of the net rope is connected to the suspension ring. A right connecting bolt 10 is fixed to the lower end of the right wheel frame 8. The right connecting bolt 10 is vertically threadedly connected with the right bracket 7. A right idler wheel 9 is connected to the right wheel frame 8.

[0028] A net 11 is arranged between the left bracket 3 and the right bracket 7. A horizontal sliding sleeve (this sliding sleeve belongs to the prior art and is not shown in the figure) is fixed to the upper end of the net 11. A horizontally movable net rope 12 is arranged in the sliding sleeve. The left end of the net rope 12 passes through the upper side of the left idler wheel 4 and then goes downward to be connected to a tension adjuster 13. The right end of the net rope 12 passes through the upper side of the right idler wheel 9 and then goes downward to be connected to the suspension ring. The right end of the net 11 is connected to a right upright post 16 with adjustable horizontal position.

[0029] The using method of the table tennis net rack is as follows: The tension adjuster 13 makes the net rope 12 in a tensioned state, so as to adjust the vertical tension degree of the net 11; by horizontally moving the right upright post 16 left and right, the net 11 is kept in a tensioned state in the horizontal direction, so that the net 11 is flat up and down uniformly, meeting the national standard requirements.

[0030] Embodiment 2

[0031] This embodiment is basically the same as Embodiment 1, the difference being that: as Figure 2 shown, a support plate 27 is fixed inside the left bracket 3. The tension adjuster 13 includes a vertical tension adjusting spring 14 and a tension adjusting bolt 15. The upper end of the tension adjusting bolt 15 threadedly passes through the support plate 27 and is screwed with a first adjusting nut 28. The upper end of the tension adjusting bolt 15 can also slidably pass through the support plate 27. Due to the relatively heavy weight of the tension adjusting bolt 15 itself, the downward movement of the tension adjusting bolt 15 is restricted by the first adjusting nut 28. The top of the tension adjusting bolt 15 is connected to the lower end of the tension adjusting spring 14. The upper end of the tension adjusting spring 14 is connected to the left end of the net rope 12. By adjusting the length of the upper end of the tension adjusting bolt 15 passing through the support plate 27, the vertical height of the tension adjusting spring 14 is adjusted, and further the tension degree of the net rope 12 is better adjusted.

[0032] Embodiment 3

[0033] This embodiment is basically the same as Embodiment 1, except that: as Figure 1 shown, a horizontal sliding groove 17 is provided on the upper end surface of the right support 2, the lower end of the right vertical column 16 is slidably placed in the horizontal sliding groove 17, a connecting frame is provided on the right vertical column 16, the connecting frame includes a vertical connecting rod 18, right arc-shaped clamps 19 are fixed at both the upper and lower ends of the vertical connecting rod 18, the right arc-shaped clamps 19 are clamped and connected to the right vertical column 16, a horizontal adjusting screw 20 is provided on the right support 7, the left end of the horizontal adjusting screw 20 passes through the right support 7 in a threaded manner and is rotationally connected to the vertical connecting rod 18. By rotating the horizontal adjusting screw 20, the right vertical column 16 is driven to move left and right along the horizontal sliding groove 17 through the connecting frame, and then the position of the right end of the net 11 is adjusted to ensure the horizontal tension of the net 11.

[0034] As Figure 2 shown, the left end of the net 11 is connected to the left vertical column 29, a positioning hole 21 is provided on the upper end surface of the left support 1, the lower end of the left vertical column 29 is clamped in the positioning hole 21, a left arc-shaped clamp 22 is fixed on the left support 3, and the left arc-shaped clamp 22 is clamped and connected to the left vertical column 29. Through the positioning hole 21 and the left arc-shaped clamp 22, the position of the left vertical column 29 is positioned to ensure that the position of the left end of the net 11 remains unchanged.

[0035] Embodiment 4

[0036] This embodiment is basically the same as Embodiment 1, except that: as Figure 1 and 3 shown, both the left support 1 and the right support 2 include a horizontal upper plate 23, an L-shaped anti-deflection plate 24 is provided at the lower end of the horizontal upper plate 23, and a table tennis table clamping groove is formed between the horizontal upper plate 23 and the L-shaped anti-deflection plate 24. A vertical clamping screw 25 is screwed at the lower end of the L-shaped anti-deflection plate 24, the upper end of the clamping screw 25 is placed in the L-shaped anti-deflection plate 24, and a clamping pad 26 is rotatably connected. The horizontal upper plate 23 is placed on the upper surface of the table tennis table, the edge of the table tennis table is placed between the horizontal upper plate 23 and the L-shaped anti-deflection plate 24, and by rotating the clamping screw 25, the clamping pad 26 is driven to move upward, so as to clamp the edge of the table tennis table. The structural settings of the left support 1 and the right support 2, on the one hand, realize the fixation of the table tennis net rack and the table tennis table, and on the other hand, after clamping, it can prevent the net rack support from deflecting due to accidental collision during use.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
