Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that the installation methods, the communication protocols and the technical terms mentioned in the present invention are technical terms that are already clearly known in the technical field, and therefore, the explanation thereof is not repeated. Moreover, the same reference numerals are used for the same components, which do not affect and should not constitute an exact understanding of the technical solutions for a person skilled in the art.

The first embodiment is as follows:

as shown in fig. 1, a foldable and movable support for sports comprises a support body 1, a locking device 2, a net rack mounting device 3 and an auxiliary fixing device 4;

When the components are installed as shown in fig. 1-3, the locking device 2 can be unlocked only by pressing the locking device handle 18 downwards and the auxiliary fixing device handle 35 can be unlocked by lifting upwards when storage is required; the complete set of devices can then be moved using the universal wheel set 47.

When the device is used, the whole device is moved to a required occasion by using the universal wheel set, and then the support bolt adjusting assembly 48 is adjusted to enable the universal wheel set to be separated from the ground so as to increase the friction force; then, each handle is moved in the direction opposite to the moving direction to realize locking.

In the invention, the counterweight is arranged at the bottom of the support, so that the stability of the support is greatly improved; when the badminton is used in a common badminton use occasion, only the locking device 2 needs to be locked, and at the moment, the impact action of the badminton on the net is buffered by the net, so that the basic requirements of sports games can be met; for tennis or volleyball use occasions, due to the fact that the ball body is large in mass and impact force is large, the lower end of the vertical support 6 of the support body is fixedly connected with the vertical support partition plate 27, the impact force received by the vertical support partition plate 27 is transmitted to the locking wedge block 21, the locking wedge block is in a locking state, the lever effect is generated due to the vertically staggered acting force, the locking effect is better, if the auxiliary fixing device 4 is reused for hooking and locking the extending portion of the first pin shaft 7, the locking effect is better, and the tennis or volleyball match requirements can be greatly met.

In addition, it is obvious to those skilled in the art that since the drawings in the specification of the present invention are not strict engineering drawings, but are only schematic illustration diagrams, it is possible to understand the technical solution of the present invention only by means of the drawings in some spatial arrangements that the problems of motion interference and the like exist (for example, in order to explain the above locking principle, especially the impact resistance effect of the present invention in impact, the state between the horizontal bracket 5 of the seat body and the vertical bracket 6 of the seat body pivoting is not shown, the vertical state of the two is shown, but those skilled in the art can fully understand that they are pivoted with sufficient clearance, the illustration in the drawings should not be limited, and they should be objectively identified and understood according to the written description of the present invention and the capability of those skilled in the art).

It will also be apparent to those skilled in the art that the upper part of the vertical support 6 of the support body or the upper part itself can adopt a telescopic rod piece to facilitate the storage and the height adjustment; the rack mounting means may be in the form of a hook or a sliding seat in a mobile form, all of which are well known and used by those skilled in the art.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. 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.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any minor modifications, equivalent replacements and improvements made to the above embodiment according to the technical spirit of the present invention should be included in the protection scope of the technical solution of the present invention.
