Description
Technical field
The invention belongs to sports apparatus field, specifically refer to total for the tennis net braces of the sports centers such as tennis or shuttlecock
Into.
Background technology
The motion such as tennis or shuttlecock is a kind of ball game mode that people like, is needed in this kind of sports center
Device net is separately poised for battle the zone of action of both sides to wait, while intercepting undesirable ball;Net by both sides hack lever branch
Support, hack lever is then fixed to be embedded to underground or is connected by mass, and the stability of fixed buried hack lever is good but limits place
Flexible utilization, also the inconvenient net to fluffing be finely adjusted;The hack lever connected by mass often selects a hollow case
Formula thing puts into inside sand to increase weight to increase the stability of hack lever, the stability of this frame net mode can also, but compared with
Big counterweight also make it that its movement is very inconvenient, real situation be the net that tensed originally after using some times because of stress or
Fluffing for natural material aging certainty is sagging, and excessively sagging can influence to use, and frequently changes net for popular
Body building place for be also impossible to, this be accomplished by both sides support net hack lever outwards fine setting with stretching ball
Net makes it return to the state in accordance with the standard of setting, it is clear that larger counterweight make it that hack lever movement is highly difficult, and this place is a variety of
The imperfection of frame net facility is it will be apparent that being sought after improving.
The content of the invention
The purpose of the present invention is the net and the new skill of hack lever for providing a kind of tennis or badminton field apparatus
Art scheme tennis net braces assembly, it can eliminate a variety of not enough problems listed by said apparatus.
The technical proposal of the invention is realized in this way, and it includes net, hack lever, ballast box, is filled under the ballast box
Be equipped with four Load-bearing box wheels, each case wheel have under its side wheel face towards net direction between a wedge-shaped voussoir, voussoir by
I-shaped tapered bar is fixedly connected, and tapered bar passes through two sleeve pipes and its activity for being fixed on that ballast box is gone to the bottom by the bar in the middle of it
Connection, to the bar upper sleeve through between the outer side pole of tapered bar has a helical spring, the inner end bar of tapered bar in the outer end of the sleeve pipe of outside
The inner edge line of ballast box is protruded from inwards, while to be each provided with one round and smooth for the tapered bar lower edge also at two sleeve pipe left end positions
Projection;One fork arm, which is passed down through, to be installed on the fork arm pipe of the inboard facade of ballast box and is flexibly connected with it, at the divergent ends of fork arm
All make inclined-plane oblique surface machining inwards in lower end and termination and non homogeneity end face, the lower end of fork arm also touches the I-shaped wedge under it
The lateral surface of the inner end bar of bar.
The beneficial effects of the invention are as follows that can allow hack lever together with ballast box arbitrarily to adjust movement, stretching net and it can constantly protect
The stability of rack is held, easily net and hack lever, ballast box can also be pushed away and moved during flexible using area, it is convenient real
With.

Embodiment:
Illustrate the design below in conjunction with the accompanying drawings.
Net 1 of the design between each hack lever 2, the hack lever of ballast box 3 and two of the office left and right sides is constituted, and hack lever is solid
Due on ballast box, the hack lever and ballast box symmetrical mounting of both sides, as Fig. 1 the design illustrates the general assembly front view institute of rack assembly
Show;Device has four Load-bearing box wheels 4 as dolly on bottom under ballast box 3, and it can make ballast box light together with hack lever
The movement of pine, each case wheel has a wedge-shaped voussoir 5 i.e. often under the ballast box of side under its side wheel face towards net direction
There are four voussoirs supporting with case wheel, the wheel face wedge angle that it can be filled up between case wheel and ground thereby can effectively prevent case
Wheel is in the rolling that this side up;Between four voussoirs by one vertical view effect be fixedly connected in I-shaped tapered bar 6, as Fig. 2, Fig. 3,
Shown in Fig. 6, Fig. 7(Ballast box and hack lever on the left of using net assembly is example plots), tapered bar 6 also passed through by bar in the middle of it
Two concentric same specification sleeve pipes 9 for being fixed on the bottom of ballast box 3 are flexibly connected with it, the sleeve pipe in outside(Relative to ball
For the direction of net, i.e., the direction of net side is inner, and the sleeve pipe for the inside in two sleeve pipes close to net is away from net
The sleeve pipe of outside)Outer end to tapered bar outer side pole(Left side bar)Between bar upper sleeve through have one be in by the helical spring of compression shape
7(As shown in Figure 6), can thereby allow tapered bar to drive voussoir to stopper case wheel to reach the purpose of stop;The inner end bar of tapered bar(That is work
The bar kept right of font tapered bar)The inner edge line of ballast box is slightly protruded from inwards(As shown in Figure 6), while also at the place of tapered bar lower edge
Position near the left end of two sleeve pipes 9 is each provided with a round and smooth projection 8, and it can slide into sleeve pipe when tapered bar is moved to right
Internal cause footprint characteristic convex under it slightly raise tapered bar and voussoir so that voussoir is separated from the contact with ground(Such as Fig. 3 institutes
Show);One wishbone is that fork arm 11 is passed down through that to be installed on ballast box 3 inboard(Right side)The fork arm pipe 10 of facade immediate vicinity and its
It is flexibly connected, the divergent ends of fork arm 11 are in lower end and inclined-plane is all made inwards in termination(To the right)Oblique surface machining and non homogeneity end face
(As shown in Fig. 2 Fig. 3 Fig. 4 Fig. 5), the lower end of fork arm also touches the lateral surface of the inner end bar of the I-shaped tapered bar under it, thereby
Can when required by it is lower by fork arm by fork arm lower surface inclined-plane inwards(To the right)Support pushes away tapered bar(As shown in Fig. 3, Fig. 5).
So, the basic structure composition of the tennis net braces assembly of the design is just described, and concrete operations are in use, working as needs both sides
Outwards regulation when moving of case wheel(Purpose is that stretching net eliminates the too sagging of net middle part), operator can be first
Original voussoir in lock-out state by fork arm 11 is disengaged it from into open lock-out state by lower, i.e., from Fig. 2, Fig. 4 shape be changed into Fig. 3,
Fig. 5 shapes, as it was previously stated, therefore voussoir 5 regulation can operate and move up some distances to the right, have been separated from and case wheel and ground
Locking contact, case wheel be free to not receive the left-right rotation of limitation, then can push out the segment distance of ballast box one
Net is set to reach tensioning(Only the ballast box of operation side or all outside of both sides it can elapse)Fork arm is moved up after shape again by tapered bar
And voussoir sets back under the resilient force of spring, i.e., the locking state of Fig. 2, Fig. 4 shape is returned to by Fig. 3, Fig. 5 shape, it is complete
Into the regulation operation of once tensioning net;Also it is in addition same when place because flexibly being removed frame net assembly using needs completely
Mode of operation, the light promotion that the hack lever and ballast box for being separated from locking state can be as small handcarts, and once locking
Then can possess sufficient one way stable again, having reached can finely tune and easily push open and can be motionless easily with fixed position
Purpose of design, greatly meet the body building needs of such place people.
