Abstract
A net fixing rack structure includes a base, a fixing tube, and a mounting tube. The base is formed with an oblique through hole. The fixing tube has a first end formed with a pin rod and a screw portion and a second end formed with a transverse through hole. The mounting tube is mounted on the fixing tube. The oblique through hole of the base has a determined inclined angle, so that the fixing tube is fixed in the ground with a determined inclined angle. Thus, after the whole net fixing rack structure is assembled, the mounting tube is inclined relative to the ground with a determined angle, thereby enhancing the supporting effect of the net fixing rack structure.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a net fixing rack structure, and more particularly to a net fixing rack structure that after assembly is inclined relative to the ground with a determined angle, thereby enhancing the supporting effect of the net fixing rack structure.
2. Description of the Related Art
A conventional net fixing rack structure in accordance with the prior art shown in
FIGS. 1 and 2
is mounted on each of two opposite sides of a net
50
A, and comprises a tube
20
A having an upper end secured on each of the two opposite sides of the net
50
A, and a fixing block
40
made of steel material secured on a lower end of the tube
20
A. However, the fixing block
40
is fixed on the ground by a tool, such as a hammer, thereby easily injuring the user by the hammer. In addition, the friction between the fixing block
40
and the ground is insufficient, so that the fixing block
40
easily detaches from the ground.
SUMMARY OF THE INVENTION
The present invention has arisen to mitigate and/or obviate the disadvantage of the conventional net fixing rack structure.
The primary objective of the present invention is to provide a net fixing rack structure, wherein the oblique through hole of the base has a determined inclined angle, so that the fixing tube is fixed in the ground with a determined inclined angle. Thus, after the whole net fixing rack structure is assembled, the mounting tube is inclined relative to the ground with a determined angle, thereby enhancing the supporting effect of the net fixing rack structure.
Another objective of the present invention is to provide a net fixing rack structure, wherein when the fixing tube is fixed in the ground, the screw portion of the fixing tube has a better grabbing effect, thereby enhancing the combination effect between the fixing tube and the ground, so that the fixing tube is fixed in the ground rigidly and stably.
A further objective of the present invention is to provide a net fixing rack structure, wherein the fixing tube is successively rotated and moved downward until the transverse through hole of the fixing tube is flush with the oblique through hole of the base, so that the user may assure that the fixing tube is inserted into the ground to a determined depth, thereby enhancing the safety of mounting the net fixing rack structure.
In accordance with the present invention, there is provided a net fixing rack structure, comprising a base, a fixing tube, and a mounting tube, wherein:
the base is mounted on the ground, and is formed with an oblique through hole having a proper height;
the fixing tube is mounted on the base, and has a first end formed with a pin rod and a second end formed with a transverse through hole, the fixing tube includes a screw portion mounted on a periphery of the pin rod, the screw portion and the pin rod of the fixing tube are extended through the oblique through hole of the base; and
the mounting tube is mounted on the fixing tube, and has a distal end connected to the oblique through hole of the base.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings and initially to
FIGS. 3-6
, a net fixing rack structure in accordance with a first embodiment of the present invention is mounted on each of two opposite sides of a net
50
(see FIG.
6
), and comprises a base
30
, a fixing tube
10
, and a mounting tube
20
.
The base
30
is mounted on the ground, and is formed with an oblique through hole
31
having a proper height.
The fixing tube
10
is mounted on the base
10
, and has a first end formed with a pin rod
13
and a second end formed with a transverse through hole
14
. The fixing tube
10
includes a screw portion
11
mounted on a periphery of the pin rod
13
. In addition, the screw portion II and the pin rod
13
of the fixing tube
10
are extended through the oblique through hole
31
of the base
30
.
The mounting tube
20
is mounted on the fixing tube
10
, and has a distal end connected to the oblique through hole
31
of the base
30
.
As shown in
FIG. 4
, the base
30
is initially placed on the ground. Then, the screw portion
11
and the pin rod
13
of the fixing tube
10
are extended through the oblique through hole
31
of the base
30
. Then, an object (not shown), such as a rod, is inserted into the transverse through hole
14
of the fixing tube
10
to rotate the fixing tube
10
, so that the screw portion
11
of the fixing tube
10
is rotated by rotation of the fixing tube
10
and is displaced downward into the ground in a helical manner. Then, the fixing tube
10
is successively rotated and moved downward until the transverse through hole
14
of the fixing tube
10
is flush with the oblique through hole
31
of the base
30
, thereby accomplishing the fixing operation, so that the screw portion
11
and the pin rod
13
of the fixing tube
10
are fixed in the ground.
As shown in
FIG. 5
, the mounting tube
20
is mounted on the fixing tube
10
, thereby assembling the net fixing rack structure in accordance with the present invention.
As shown in
FIG. 6
, each of the two opposite sides of the net
50
is secured on the upper end of the mounting tube
20
of the net fixing rack structure in accordance with the present invention.
Referring to
FIG. 7
, the net fixing rack structure in accordance with a second embodiment of the present invention is shown, wherein the screw portion
11
of the fixing tube
10
is enlarged, and presents a flat and smooth face.
Referring to
FIG. 8
, the net fixing rack structure in accordance with a third embodiment of the present invention further comprises an elongated rod
16
extended through the transverse through hole
14
of the fixing tube
10
. Preferably, the elongated rod
16
is integrally formed in the transverse through hole
14
of the fixing tube
10
. In addition, the screw portion
11
and the pin rod
13
of the fixing tube
10
are integrally formed with each other.
Accordingly, the net fixing rack structure in accordance with the present invention has the following advantages.
1. The oblique through hole
31
of the base
30
has a determined inclined angle, so that the fixing tube
10
is fixed in the ground with a determined inclined angle. Thus, after the whole net fixing rack structure is assembled, the mounting tube
20
is inclined relative to the ground with a determined angle, thereby enhancing the supporting effect of the net fixing rack structure.
2. When the fixing tube
10
is fixed in the ground, the screw portion
11
of the fixing tube
10
has a better grabbing effect, thereby enhancing the combination effect between the fixing tube
10
and the ground, so that the fixing tube
10
is fixed in the ground rigidly and stably.
3. The fixing tube
10
is successively rotated and moved downward until the transverse through hole
14
of the fixing tube
10
is flush with the oblique through hole
31
of the base
30
, so that the user may assure that the fixing tube
10
is inserted into the ground to a determined depth, thereby enhancing the safety of mounting the net fixing rack structure.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
