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.
